Definitions
- the present invention encompasses a building component used to form a corner in a wall system and, more particularly, a corner for a system that is used to construct a concrete wall.
- Concrete walls in building construction are often produced by first setting up two parallel form walls and pouring concrete into the space between the forms. After the concrete hardens, the builder then removes the forms, leaving the cured concrete wall.
- the present invention comprises a panel connector for making corner structures in building form systems, particularly for systems used to construct concrete walls.
- the panel connector defines two channels into which respective portions of the side panels are inserted, preferably at the construction site. These panel connectors are designed to form a corner having a predetermined angle to which the inserted side panels are positioned.
- the panel connector includes a first base wall, a first pair of side walls, and a second pair of side walls.
- the first pair of side walls extend from the first base wall and are spaced apart to define a first channel of a size to complementarily receive a portion of one side panel.
- One of the side walls of the first pair of side walls forms a second base wall, and the second pair of side walls extend from the second base wall to form the second channel.
- the second channel is also of a size to complementarily receive a portion of another side panel.
- the side panels are usually oriented at right angles to each other in plan view.
- the panel connector comprises a pair of connected channels.
- Each channel includes a first side wall, a second side wall, and a back wall. Both channels have corners formed between the first side wall and the back wall and those corners are connected to each other.
- the side walls for each channel that do not form the corner of that respective channel may extend beyond the connection point of the respective back wall to a distal edge.
- the distal edges of the second side walls of both channels are also connected.
- the panel connector may be formed so that the connected corners of the channels are coextensive and integral with each other and the distal edges of the connected channels are also coextensive and integral with each other.
- the back walls of the respective channels are at an angle with each other in plan view that is less than 180 degrees.
- the back walls are at angles of either 45 or 90 degrees and the side panels accordingly, are at that same angle in plan view.
- the panel connector may also include a fastening means for forming a stronger connection between the panel connector and the respective inserted side panels.
- the fastening means assists in maintaining the side panels within the respective channels during the construction process and after its completion.
- the present invention also includes a method of constructing a portion of a form wall system having at least one panel connector described herein and at least two side panels.
- FIG. 1 is a perspective view of one embodiment of the present invention shown being used with an exemplary wall system.
- FIG. 2 is a perspective side view of a FIG. 1 taken along line 2 - 2 .
- FIG. 2A is an alternative view of FIG. 2 showing concrete disposed between the two opposed side panels.
- FIG. 3 is a perspective view of connector shown in FIG. 2.
- FIG. 4 is a perspective view of a first exemplary embodiment of a panel connector of the present invention.
- FIG. 5 is a top plan view of the panel connector of FIG. 4 having a portion of a respective side panel disposed within each of the two channels.
- FIG. 6 is a top plan view of T-wall formed using two panel connectors shown in FIG. 4.
- FIG. 7 is a perspective view of a second exemplary embodiment of a panel connector of the present invention.
- FIG. 8 is a top plan view of the panel connector of FIG. 7 having a portion of a respective side panel disposed within each of the two channels, in which the side panels are oriented at an approximately 45 degree angle to each other.
- FIG. 9 is a top plan view of a panel connector similar to that of FIG. 7, in which the side panels are oriented at an angle of approximately 90 degrees instead of at 45 degrees.
- the present invention comprises a corner system 10 used for constructing buildings and the like.
- exemplary components that are used to form the associated concrete form wall are addressed to provide context.
- each side panel 20 has a top end 24 , a bottom end 26 , a first end 28 , a second end 30 , an exterior surface 32 , and an interior surface 34 .
- the illustrated side panel 20 has a thickness (separation between the interior surface 34 and exterior surface 32 ) of approximately two and a half (21 ⁇ 2) inches, a height (separation between the bottom end 26 and the top end 24 ) of sixteen (16) inches, and a length (separation between the first end 28 and second end 30 ) of forty-eight (48) inches.
- the dimensions may be altered, if desired, for different building projects, such as increasing the thickness of the side panel 20 for more insulation.
- Half sections of the side panels 20 can be used for footings.
- the interior surface 34 of one side panel 20 faces the interior surface 34 of another side panel 20 and the opposed interior surfaces 34 are laterally spaced apart from each other a desired separation distance so that a cavity 38 is formed therebetween.
- the opposed interior surfaces 34 are usually parallel to each other.
- the volume of concrete received within the cavity 38 is defined by the separation distance between the interior surfaces 34 , the height of the side panels 20 , and the length of the side panels 20 .
- the illustrated side panels 20 are constructed of expanded polystyrene (“EPS”), which provides thermal insulation and sufficient strength to hold the poured concrete C until it substantially cures.
- EPS expanded polystyrene
- the formed concrete wall using expanded polystyrene with the poured concrete C has a high insulating value so that no additional insulation is usually required.
- the formed walls have a high impedance to sound transmission.
- the side panels may be formed of the same material or different materials.
- other materials including, but not limited to, other polystyrene materials, wood, plywood, combined steel frame and plywood center (commonly known as a steel-ply panel), or any other solid material that can be coupled to either a web member 40 or a connector 50 and can withstand the forces exerted by the fluid concrete when poured into the cavity 38 without substantial bowing, warping, breaking, or other type of failure.
- the opposed side panels may be formed of the same material or different materials.
- each side panel 20 has at least one web member 40 formed into it.
- Each web member 40 formed within one side panel 20 is usually separated a predetermined longitudinal distance from other web members 40 , which is typically eight (8) inches. Based on the preferred length of the side panel 20 of forty-eight (48) inches, six web members 40 are formed within each side panel 20 .
- each web member 40 is shown integrally formed within one side panel 20 and is to be cured within the concrete C so that the web member 40 strengthens the connection between the side panel 20 and the concrete C. That is, since the web member 40 is an integral part of the side panel 20 , it bonds the side panel 20 to the concrete C once the concrete is poured and substantially cures within the cavity 38 .
- other designs are contemplated to be used with the present invention, such as systems in which the web member is not integrally formed into the side panel and, for example, the web member is slid into slots precut into the side panel at the construction site.
- Still another design with which the present invention may be used includes systems having the web members, side panels, and connectors shipped to the construction site as an integral unit. Such exemplary designs are disclosed in U.S. Pat. Nos. 4,901,494, 5,390,459, and 5,497,592, which are also incorporated herein in by reference.
- each web member 40 that extend through the interior surface 34 of the side panel 20 forms one or more attachment points 44 .
- the attachment points 44 are disposed within the cavity 38 and are spaced apart from the interior surface 34 of the side panels 20 .
- the attachment points 44 may take any of a number of alternate designs formed by or independentl of the web members 40 , including as examples: slots, channels, grooves, projections or recesses formed in the side panels; hooks or eyelets projecting from or formed into the side panels; twist, compression or snap couplings; or other coupling means for engaging cooperating ends of the connectors.
- the illustrated attachment points 44 of the web members 40 extend into the cavity 38 and the attachment points 44 of each web member 40 formed within one side panel 20 are spaced apart from the attachment points 44 of the web members 40 formed within the opposed side panel 20 .
- the web members 40 in this illustrative design do not directly contact each other; instead, each attachment point 44 independently engages the connector 50 that interconnects the web members 40 and, accordingly, the side panels 20 .
- the illustrated connector 50 has opposed ends 52 and a length extending therebetween.
- the ends 52 of the connectors 50 are each of a shape to engage one attachment point 44 of two respective web members 40 within opposed panels.
- each end 52 of the connector 50 has a track 54 into which the attachment point 44 is complementarily and slidably received.
- the illustrated connectors 50 engage two attachment points 44 on opposed web members 40 , which position the interior surfaces 34 of the side panels 20 at a desired separation distance and support the side panels 20 when the fluid concrete is poured into the cavity 38 .
- the connector 50 thus makes a two-point connection with opposed web members 40 because each connector has two ends 52 that each couple to one attachment point 44 , although it is contemplated making a four-point connection (i.e., each connector 50 engages four attachment points 44 instead of two as illustrated in the figures).
- the web members and connectors can be formed as an integral unit for use with the present invention.
- the connectors 50 also define an aperture 56 of a size to complementary receive a re-bar (not shown) therein.
- the re-bar provides reinforcing strength to the formed wall.
- the diameter of the re-bar can be one-quarter (1 ⁇ 4) inch or other dimension as required for the necessary reinforcement, which depends on the thickness of the concrete wall and the design engineering requirements.
- the connectors 50 usually have two or more apertures 56 and re-bar can be positioned in any of the apertures 56 before the concrete is poured into the cavity 38 .
- the apertures 56 can be designed so that the re-bar is securably snapped into place for ease of assembly.
- different connectors 50 can have varying lengths.
- the width of the cavity 38 can be two (2), four (4), six (6), eight (8) inches or other separation.
- Different connectors 50 are sized accordingly to obtain the desired width of the cavity 38 .
- the fire rating, sound insulation, and thermal insulation increase as the width of the cavity 38 , which is filled with concrete, increases.
- the cavity 38 may only be partially filled with concrete, but such an embodiment is usually not desired.
- the web members 40 and connectors 50 are usually constructed of a thermoplastic, but other materials may be used. Factors used in choosing the material include the desired strength of the web member 40 and connector 50 , the compatibility with the material used to form side panels 20 and with the concrete, and cost. Another consideration is that the end plates of the web members (positioned adjacent the exterior surface of the side panel 20 ) should be adapted to receive and frictionally hold a metal fastener, such as a nail or screw, therein, thus providing the “strapping” for a wall system that provides an attachment point for gypsum board (not shown), interior or exterior wall cladding (not shown), or other interior or exterior siding (not shown).
- a metal fastener such as a nail or screw
- a plurality of side panels 20 can be longitudinally aligned to form a predetermined length and be vertically stacked to form a predetermined height.
- first end 28 of one side panel 20 abuts the second end 30 of another side panel 20 and the bottom end 26 of one side panel 20 is disposed on the top end 24 of another side panel 20 .
- a series of side panels 20 can be aligned and stacked to form the concrete system into which concrete C is poured to complete the construction of the wall.
- the side panels 20 are not vertically stacked too high and filled at once so that the pressure on the bottom side panel 20 is greater than the yield strength of the web members 40 or side panels 20 .
- the stacked wall of panels 20 can be filled and cured in stages so that the static and dynamic pressures are not excessive on the lower side panels 20 .
- the side panels 20 are optionally provided with a series of projections 35 and indentations 37 that complementarily receive offset projections 35 and indentations 37 from another side panel 20 (i.e., a tongue-and-groove-type system) to facilitate the stacking of the components.
- the projections 35 and indentations 37 in the adjacent side panels 20 mate with each other to form a tight seal that prevents leakage of concrete C during wall formation and prevents loss of energy through the formed wall.
- the present invention comprises a panel connector 60 that is used to form a corner of the wall structure.
- the panel connector 60 which is shown in FIGS. 1 and 4- 9 , joins or interconnects two or more side panels 20 in a fixed or stationary relationship relative to each other.

Description
- This patent application claims priority to U.S. Provisional Application Serial No. 60/271,827, which was filed on Feb. 27, 2001, and which is fully incorporated herein by reference.
- 1. Field of the Invention
- The present invention encompasses a building component used to form a corner in a wall system and, more particularly, a corner for a system that is used to construct a concrete wall.
- 2. Background Art
- Concrete walls in building construction are often produced by first setting up two parallel form walls and pouring concrete into the space between the forms. After the concrete hardens, the builder then removes the forms, leaving the cured concrete wall.
- This prior art technique has drawbacks. Formation of the concrete walls is inefficient because of the time required to erect the forms, wait until the concrete cures, and take down the forms. This prior art technique, therefore, is an expensive, labor-intensive process.
- Accordingly, techniques have developed for forming concrete walls that use a foam insulating material. The modular form walls are set up parallel to each other and connecting components hold the two form walls in place relative to each other while concrete is poured therebetween. The form walls, however, remain in place after the concrete cures. That is, the modular walls, which are constructed of foam insulating material, are a permanent part of the building after the concrete cures. The concrete walls made using this technique can be stacked on top of each other many stories high to form all of a building's walls. In addition to the efficiency gained by retaining the form walls as part of the permanent structure, the materials of the form walls often provide adequate insulation for the building.
- In prior art systems, however, the corners for form systems have proven to be difficult to manufacture and construct. Often a specific side panel must be manufactured and used, in which the side panels are non-linear to form an angle equal to that required for the building (i.e., 90 degrees). These corner panels necessary to make a corner structure in the prior art concrete form systems are expensive which, in turn, increases the cost of the formed wall.
- The present invention comprises a panel connector for making corner structures in building form systems, particularly for systems used to construct concrete walls. The panel connector defines two channels into which respective portions of the side panels are inserted, preferably at the construction site. These panel connectors are designed to form a corner having a predetermined angle to which the inserted side panels are positioned.
- In one exemplary embodiment, the panel connector includes a first base wall, a first pair of side walls, and a second pair of side walls. The first pair of side walls extend from the first base wall and are spaced apart to define a first channel of a size to complementarily receive a portion of one side panel. One of the side walls of the first pair of side walls forms a second base wall, and the second pair of side walls extend from the second base wall to form the second channel. The second channel is also of a size to complementarily receive a portion of another side panel. With this embodiment, the side panels are usually oriented at right angles to each other in plan view.
- In a second exemplary embodiment, the panel connector comprises a pair of connected channels. Each channel includes a first side wall, a second side wall, and a back wall. Both channels have corners formed between the first side wall and the back wall and those corners are connected to each other. The side walls for each channel that do not form the corner of that respective channel (e.g., the second side panel) may extend beyond the connection point of the respective back wall to a distal edge. For structural integrity, it is preferred that the distal edges of the second side walls of both channels are also connected. In fact, the panel connector may be formed so that the connected corners of the channels are coextensive and integral with each other and the distal edges of the connected channels are also coextensive and integral with each other.
- In this second embodiment, the back walls of the respective channels are at an angle with each other in plan view that is less than 180 degrees. In specific preferred embodiments, the back walls are at angles of either 45 or 90 degrees and the side panels accordingly, are at that same angle in plan view.
- The panel connector may also include a fastening means for forming a stronger connection between the panel connector and the respective inserted side panels. The fastening means assists in maintaining the side panels within the respective channels during the construction process and after its completion.
- The present invention also includes a method of constructing a portion of a form wall system having at least one panel connector described herein and at least two side panels.

- The present invention is more particularly described in the following examples that are intended as illustrative only since numerous modifications and variations therein will be apparent to those skilled in the art. As used in the specification and in the claims, “a,” “an,” and “the” can mean one or more, depending upon the context in which it is used. The preferred embodiment of the present invention is now described with reference to the figures, in which like numbers indicate like parts throughout the figures.
- As shown in FIGS.1-9, the present invention comprises a
corner system 10 used for constructing buildings and the like. Before describing illustrative embodiments of the present invention, however, exemplary components that are used to form the associated concrete form wall are addressed to provide context. - As best shown in FIG. 2,
side panels 20 are used to form the wall, in which eachside panel 20 has atop end 24, abottom end 26, afirst end 28, asecond end 30, anexterior surface 32, and aninterior surface 34. The illustratedside panel 20 has a thickness (separation between theinterior surface 34 and exterior surface 32) of approximately two and a half (2½) inches, a height (separation between thebottom end 26 and the top end 24) of sixteen (16) inches, and a length (separation between thefirst end 28 and second end 30) of forty-eight (48) inches. The dimensions may be altered, if desired, for different building projects, such as increasing the thickness of theside panel 20 for more insulation. Half sections of theside panels 20 can be used for footings. - Referring now to FIGS. 1 and 2, the
interior surface 34 of oneside panel 20 faces theinterior surface 34 of anotherside panel 20 and the opposedinterior surfaces 34 are laterally spaced apart from each other a desired separation distance so that acavity 38 is formed therebetween. Concrete—in its fluid state—is poured into thecavity 38 and allowed to substantially cure (i.e., harden) therein to form the wall structure, as shown in FIG. 2A. The opposedinterior surfaces 34 are usually parallel to each other. The volume of concrete received within thecavity 38 is defined by the separation distance between theinterior surfaces 34, the height of theside panels 20, and the length of theside panels 20. - The illustrated
side panels 20 are constructed of expanded polystyrene (“EPS”), which provides thermal insulation and sufficient strength to hold the poured concrete C until it substantially cures. The formed concrete wall using expanded polystyrene with the poured concrete C has a high insulating value so that no additional insulation is usually required. In addition, the formed walls have a high impedance to sound transmission. However, other materials may be used to form the side panels, including, but not limited to, other polystyrene materials, wood, plywood, combined steel frame and plywood center (commonly known as a steel-ply panel), or any other solid material that can be coupled to either aweb member 40 or aconnector 50 and can withstand the forces exerted by the fluid concrete when poured into thecavity 38 without substantial bowing, warping, breaking, or other type of failure. The opposed side panels may be formed of the same material or different materials. - As shown in FIG. 2 and disclosed more completely in U.S. Pat. Nos. 6,170,220 and 6,336,301 and in U.S. patent application Ser. No. 09/848,398 (all of which are incorporated herein in their entireties), each
side panel 20 has at least oneweb member 40 formed into it. Eachweb member 40 formed within oneside panel 20 is usually separated a predetermined longitudinal distance fromother web members 40, which is typically eight (8) inches. Based on the preferred length of theside panel 20 of forty-eight (48) inches, sixweb members 40 are formed within eachside panel 20. A portion of eachweb member 40 is shown integrally formed within oneside panel 20 and is to be cured within the concrete C so that theweb member 40 strengthens the connection between theside panel 20 and the concrete C. That is, since theweb member 40 is an integral part of theside panel 20, it bonds theside panel 20 to the concrete C once the concrete is poured and substantially cures within thecavity 38. However, other designs are contemplated to be used with the present invention, such as systems in which the web member is not integrally formed into the side panel and, for example, the web member is slid into slots precut into the side panel at the construction site. Still another design with which the present invention may be used includes systems having the web members, side panels, and connectors shipped to the construction site as an integral unit. Such exemplary designs are disclosed in U.S. Pat. Nos. 4,901,494, 5,390,459, and 5,497,592, which are also incorporated herein in by reference. - Referring still to FIG. 2, portions of each
web member 40 that extend through theinterior surface 34 of theside panel 20 forms one or more attachment points 44. The attachment points 44 are disposed within thecavity 38 and are spaced apart from theinterior surface 34 of theside panels 20. However, as one skilled in the art will appreciate, the attachment points 44 may take any of a number of alternate designs formed by or independentl of theweb members 40, including as examples: slots, channels, grooves, projections or recesses formed in the side panels; hooks or eyelets projecting from or formed into the side panels; twist, compression or snap couplings; or other coupling means for engaging cooperating ends of the connectors. - The illustrated attachment points44 of the
web members 40 extend into thecavity 38 and the attachment points 44 of eachweb member 40 formed within oneside panel 20 are spaced apart from the attachment points 44 of theweb members 40 formed within theopposed side panel 20. Thus, theweb members 40 in this illustrative design do not directly contact each other; instead, each attachment point 44 independently engages theconnector 50 that interconnects theweb members 40 and, accordingly, theside panels 20. - Referring now to FIG. 3, the illustrated
connector 50 has opposed ends 52 and a length extending therebetween. The ends 52 of theconnectors 50 are each of a shape to engage one attachment point 44 of tworespective web members 40 within opposed panels. In conjunction, eachend 52 of theconnector 50 has atrack 54 into which the attachment point 44 is complementarily and slidably received. Thus, the illustratedconnectors 50 engage two attachment points 44 onopposed web members 40, which position theinterior surfaces 34 of theside panels 20 at a desired separation distance and support theside panels 20 when the fluid concrete is poured into thecavity 38. Theconnector 50 thus makes a two-point connection withopposed web members 40 because each connector has two ends 52 that each couple to one attachment point 44, although it is contemplated making a four-point connection (i.e., eachconnector 50 engages four attachment points 44 instead of two as illustrated in the figures). As also noted above, however, the web members and connectors can be formed as an integral unit for use with the present invention. - Referring now to FIGS. 2 and 3, the
connectors 50 also define anaperture 56 of a size to complementary receive a re-bar (not shown) therein. The re-bar provides reinforcing strength to the formed wall. The diameter of the re-bar can be one-quarter (¼) inch or other dimension as required for the necessary reinforcement, which depends on the thickness of the concrete wall and the design engineering requirements. Theconnectors 50 usually have two ormore apertures 56 and re-bar can be positioned in any of theapertures 56 before the concrete is poured into thecavity 38. Theapertures 56 can be designed so that the re-bar is securably snapped into place for ease of assembly. - To alter the width of the cavity38 (i.e., the separation between the
interior surfaces 34 of the opposed side panels 20),different connectors 50 can have varying lengths. The width of thecavity 38 can be two (2), four (4), six (6), eight (8) inches or other separation.Different connectors 50 are sized accordingly to obtain the desired width of thecavity 38. Also, as one skilled in the art will appreciate, the fire rating, sound insulation, and thermal insulation increase as the width of thecavity 38, which is filled with concrete, increases. One skilled in the art will appreciate that thecavity 38 may only be partially filled with concrete, but such an embodiment is usually not desired. - The
web members 40 andconnectors 50 are usually constructed of a thermoplastic, but other materials may be used. Factors used in choosing the material include the desired strength of theweb member 40 andconnector 50, the compatibility with the material used to formside panels 20 and with the concrete, and cost. Another consideration is that the end plates of the web members (positioned adjacent the exterior surface of the side panel 20) should be adapted to receive and frictionally hold a metal fastener, such as a nail or screw, therein, thus providing the “strapping” for a wall system that provides an attachment point for gypsum board (not shown), interior or exterior wall cladding (not shown), or other interior or exterior siding (not shown). - Referring back to FIGS. 1 and 2, one skilled in the art will appreciate that a plurality of
side panels 20 can be longitudinally aligned to form a predetermined length and be vertically stacked to form a predetermined height. For example, thefirst end 28 of oneside panel 20 abuts thesecond end 30 of anotherside panel 20 and thebottom end 26 of oneside panel 20 is disposed on thetop end 24 of anotherside panel 20. Thus, a series ofside panels 20 can be aligned and stacked to form the concrete system into which concrete C is poured to complete the construction of the wall. One consideration, however, is that theside panels 20 are not vertically stacked too high and filled at once so that the pressure on thebottom side panel 20 is greater than the yield strength of theweb members 40 orside panels 20. Instead, the stacked wall ofpanels 20 can be filled and cured in stages so that the static and dynamic pressures are not excessive on thelower side panels 20. - Still referring to FIGS. 1 and 2, the
side panels 20 are optionally provided with a series ofprojections 35 andindentations 37 that complementarily receive offsetprojections 35 andindentations 37 from another side panel 20 (i.e., a tongue-and-groove-type system) to facilitate the stacking of the components. Theprojections 35 andindentations 37 in theadjacent side panels 20 mate with each other to form a tight seal that prevents leakage of concrete C during wall formation and prevents loss of energy through the formed wall. - In the context of these exemplary components, the present invention is disclosed, which comprises a
panel connector 60 that is used to form a corner of the wall structure. Thepanel connector 60, which is shown in FIGS. 1 and 4-9, joins or interconnects two ormore side panels 20 in a fixed or stationary relationship relative to each other. As noted above, theinterconnected side panels 20 can employ any design used in the art, ranging from plywood panels to the illustrative EPS panels illustrated in the Figures. - In a preferred embodiment, the
panel connector 60 comprises first andsecond channels back wall side walls second channels back wall side wall edges edge side wall respective end back wall side walls interconnected back wall respective channel second channels side panel 20 therein. As discussed below, thechannels side panel 20 retained within to the respective channel once interconnected. - It is also preferred that the back and
side walls side walls back wall channel side panels 20 inserted into that channel. Of course, the shape and orientation of thechannels opposed side walls back wall - For purposes of discussing the present invention, the
first channel 70 will be disclosed as receiving afirst side panel 20A and thesecond channel 80 as receiving asecond side panel 20B. The illustrated first andsecond side panels 20 are of the same design, but one skilled in the art will appreciate that thefirst side panel 20A may be an EPS panel and thesecond side panel 20B formed of a different material. Similarly, the first andsecond side panels exterior surfaces - The present invention also preferably includes a means for positioning the first and
second channels first channel 70 to a portion of thesecond channel 80. More specifically, it is preferred that thepanel connector 60 be formed or extruded so that the first andsecond channels - Similar to the exemplary web members and connectors described above, the
panel connectors 60 may be formed of plastic, more preferably high-density plastic such as high-density polyethylene or high-density polypropylene, although other suitable polymers may be used. Other contemplated plastics include acrylonitrile butadiene styrene (“ABS”) and glass-filled polyethylene or polypropylene. Likewise, other materials that may be used are other plastics and thermoplastics (including polyvinyl chloride (P.V.C.), polytetrafluoethylene (P.T.F.E.), polyamides such as nylon), metal, and natural and other synthetic materials. Factors used in choosing the material include the desired strength of thepanel connector 60, the compatibility with the material used to formside panels 20 and with the concrete C, and cost. - In the first exemplary embodiment of the present invention shown in FIGS.4-6, the positioning means comprises one
side wall 74 of thefirst channel 70 also forming theback wall 82 of thesecond channel 80 so that the first andsecond channels first back wall 72 and a first pair ofside walls 74 extending from thefirst base wall 72 to define thefirst channel 70. One of those twoside walls 74 of thefirst channel 70 forms asecond back wall 88. The second pair ofside walls 84 extend substantially perpendicular from thesecond back wall 88. Similar to the first set of side walls, the second pair ofside walls 84 are also spaced apart from each other to define thesecond channel 80. The first andsecond channels second side panels - Referring now to FIGS. 1 and 7-9, a second exemplary embodiment of the present invention is shown, in which the two channels are interconnected at one of their respective corners. Specifically, for the
first channel 70, the intersection of oneend 73 of theback wall 72 and oneedge 85 of onerespective side wall 84 forms afirst channel corner 76, and, similarly for thesecond channel 80, the intersection of oneend 83 of thatback wall 82 and anedge 85 of onerespective side wall 84 forms asecond channel corner 86. The positioning means in this embodiment comprises a portion of thefirst channel corner 76 being attached to a portion of thesecond channel corner 86. As noted above, the first andsecond channel corners panel connector 60, but other designs of the positioning means are contemplated as mentioned above. - It is preferred that that the
back walls second channels second side panels panel connector 60 form the same sized angle in plan view as the angle formed by the back walls in the illustrated embodiments. - Although not required, it is preferred for structural strength of the
panel connector 60 of this second exemplary embodiment that the channels interconnect at another point besides the first andsecond channel corners second channels - In another embodiment illustrated in FIGS.7-9, the channels include respective first and
second side extensions first side extension 90 is connected to theside wall 74 that is opposed to the side wall that forms the first channel corner 76 (i.e., the corner not connected to the second channel 80) and, likewise, thesecond side extension 94 is connected to theside wall 84 that is opposed to the side wall that forms thesecond channel corner 86. Both the first andsecond side extensions first channel 70 toward thesecond channel 80 and terminate at a respectivedistal edge distal edge 92 of thefirst side extension 90 contacts thedistal edge 96 of thesecond side extension 94 and, more preferably, the twodistal edges - Referring still to FIGS.7-9, the
first side extension 90 is substantially linear in plan view and oriented substantially perpendicular to theback wall 72 of thefirst channel 70. Likewise, thesecond side extension 94 is substantially linear in plan view and is also oriented substantially perpendicular to theback wall 82 of thesecond channel 80. The extending portion of thefirst side extension 90 and the extending portion of thesecond side extension 94 form a non-linear angle Φ therebetween. That angle Φ between the first andsecond side extensions back walls second channels 70, 80 (i.e., collectively the angles (θ+Φ) total 180 degrees). This embodiment is presently preferred because the exterior surface of the formed wall is aesthetically pleasing and provides a contiguous mounting surface when covered, such as with stucco or the like. As noted above, however, other embodiments are contemplated, such as arcuate shapes, to address all architectural designs. - As noted above, the present invention may optionally further comprise a fastening means associated with at least one of the first and
second channels respective side panel 20 within that respective channel. The embodiment of the fastening means shown in FIGS. 4, 5, and 7-9 comprises at least oneprotrusion 100 that engages theside panel 20 inserted into the channel. As illustrated, each of theside walls opposed side wall protrusions 100 are formed on the engaging surfaces of theside walls protrusion 100 is saw-tooth shaped in plan view, in which the saw-tooth shape has opposite steep and gradual sides. The gradual side generally faces the front of theside wall respective back wall channel - It is also contemplated that the
side panels 20 include anindentation 39 or detent in their respective exterior surfaces 32 of a size to receive onerespective protrusion 100 therein when theside panel 20 is fully inserted into the channel. In use, when theside panel 20 is inserted into the respective channel, at least oneindentation 39 within the interior and/or exterior surface of theside panel 20 engages the steep side of theprotrusion 100 to secure the receivedside panel 20 to the respective channel. There may be a plurality of spaced-apartprotrusions 100 on the mating surface of eachside wall indentations 39 to engage eachprotrusion 100. - Additionally, each
side wall protrusion 100 may extend substantially the lateral height of the side wall, which is greater than half the lateral height, more preferably greater than three-quarters of the lateral height, and most preferably substantially the entire lateral height. Further, eachprotrusion 100 may extend substantially parallel to theback edge - Other fastening means are also contemplated. One example of an alternative fastening means may comprise at least one orifice (not shown) in each of the side walls of the first and the second pairs of side walls and a plurality of fasteners (not shown). After the first and
second side panels second channels side panel 20. In another design, the fastening means may comprise at least one starter indentation (not shown) in each of the side walls of the first and the second pairs of side walls and a plurality of fasteners (not shown) so that one fastener may be driven through the starter indentation and into the received side panel. It is also contemplated that the fastening means may include chemical adhesives as well as other types of mechanical fasteners such as rivets, nails, screws, bolts and the like if the materials allow (i.e., when using plywood side panels). - Referring back to FIGS. 4 and 5, one of the
side walls 74 of the first pair of side walls and one of theside walls 84 of the second pair of side walls each may define a laterally extendinglip 78 formed at the front edge of the respective side wall. As one skilled in the art will appreciate, when thefirst side panel 20A is received into thefirst channel 70 and when thesecond side panel 20B is received into thesecond channel 80, the definedlips 78 extend outwardly away from theinterior surface 34 of the respective receivedside panels 20 so that a portion of thepanel connector 60 extends into thecavity 38 to be substantially cured within the concrete C. Since thelips 78 are an integral part of thepanel connector 60, the lip, assists in “locking” thepanel connector 60 to the concrete C once the concrete is poured and substantially cures within thecavity 38 around the exposed portions of thepanel connector 60. - As illustrated in FIG. 1,
multiple panel connectors 60 can be used in conjunction with each other to form the wall structure. Another example is the formation of a T-wall, which is illustrated in FIG. 6. There are two panel connectors shown: aright panel connector 60R and aleft panel connector 60L. The embodiment of thepanel connector 60 illustrated in FIGS. 4 and 5 is shown, but one skilled in the art will appreciate that other panel connector designs may similarly be used, including the embodiment shown in FIG. 9. This T-wall system also uses four side panels, including a first, a second, a third, and a fourth side panel, in which the first andsecond side panels left panel connector 60L and the third andfourth side panels side panel connector 60R. To form the T-wall, the right and leftpanel connectors first side panel 20A is oriented substantially linearly with thethird panel 20C and the second andfourth side panels fourth side panels cavity 38. As further disclosed in U.S. patent application Ser. No. 09/848,398 (which is incorporated by reference herein in its entirety),flexible linking members 62 andextenders 64 can be used to interconnect theside panels 20 and to assist in preventing bowing when fluid concrete fills thecavity 38. - Although the present invention has been described with reference to specific details of certain embodiments thereof, it is not intended that such details should be regarded as limitations upon the scope of the invention except as and to the extent that they are included in the accompanying claims. For example, as noted above, the present invention is described with reference to a system incorporating the depicted concrete form system, it will be understood by those skilled in the art that the present invention is applicable to other types of concrete form systems utilizing one or more form panels or other concrete retaining and/or molding elements retained in position by one or more connectors or other relative position-fixing elements. Also, although the present invention is described with reference to a system, method and components thereof for use in the forming of concrete building components, the present invention may also find application in the formation of various other types of products of concrete and/or other moldable and curable materials such as, for example, structural and nonstructural building components and consumer products of concrete, plastics, and other synthetic and natural materials.
