- Referring to
FIGS. 1-10 , a stackable rebar support chair, noted by thenumeral 10 is provided for supporting rebar above a surface such as dirt, rocks, sand, and the like. Referring toFIG. 1 , the stackablerebar support chair 10 includes achair support 12 and asupport plate 30 made of a generally rigid material such as plastic or metal. However, any type of material capable of supporting rebar and other construction materials can be utilized. In one example embodiment, the chair support 12 and thesupport plate 30 can be detachably coupled together for supporting rebar on soft surfaces such as sand. However, thesupport chair 12 can also be used without thesupport plate 30 to support rebar or other construction materials above harder surfaces such as rock, cement or concrete. - Referring now to
FIG. 2 , thesupport chair 12 includes abase 14 that is oriented generally horizontal to the surface or ground. The base includes anupper surface 15 and alower surface 16 oriented generally parallel to each other. Thebase 14 can include at least onehole 18 extending through the upper 15 and lower 16 surfaces to define at least onecross support 19. The at least onehole 18 permits the free flow of concrete or cement around thesupport chair 12. The free flow of concrete or cement prevents shear plans from developing and impacting the quality of the hardened concrete or cement. As illustrated in the Figures, multiple holes can be formed in thebase 14 to define multiple cross supports. The size and shape of the holes can vary depending upon the amount of free flowing concrete desired. - Referring to
FIGS. 1 , 2, and 4-6, thebase 14 includes multipleupstanding posts 20 extending from itsupper surface 15 and multiple downwardly extendinglegs 21 extending from itslower surface 16. Respectiveupstanding posts 20 andlegs 21 are generally axially aligned to each other and generally perpendicular to thebase 14 such that thebase 14 is suspended above the ground surface between theupstanding posts 20 andlegs 21. In one example embodiment, theupstanding posts 20 andlegs 21 are positioned at corners of thebase 14. However, theupstanding posts 20 and thelegs 21 can be positioned anywhere on thebase 14, thus allowing for multiple configurations. - As particularly illustrated in
FIGS. 1 , 2 and 5, theupstanding posts 20 each include asocket 22 extending therein for receiving acorresponding leg 21 when onesupport chair 12 is stacked upon anothersupport chair 12. Each of the downwardly extendinglegs 21 generally have a smaller diameter than theupstanding posts 20 to permit relatively easy insertion into thesockets 22 of theupstanding posts 20. In example embodiments of the invention, the ends of each of thelegs 21 can be generally pointed, tapered or blunt. - Referring to
FIGS. 1 , 2, and 5-6, each of theupstanding posts 20 includes at least one centering support bracket orgusset 24. Each of thecentering support brackets 24 extends between and is coupled to theupper surface 15 of thebase 14 and anupstanding post 20. Referring particularly toFIG. 6 , a pair ofcentering support brackets 24 forms a V-shape, which is designed to permit gravity assisted positioning of the rebar to a central position on thebase 14. By positioning the rebar over the central portion of thebase 14, it permits the automatic proper weight distribution over thesupport chair 12. - Referring to the example embodiment of
FIGS. 1 and 2 , there can be a plurality of centeringsupport brackets 24 such that there is a centeringbracket support system 23 to facilitate centering the rebar and supporting the posts. The centeringbracket support system 32 can include a firstcentering support bracket 24 a and a secondcentering support bracket 24 b extending between each of theupstanding posts 20 and theupper surface 15 of thebase 14 to provide increased structural rigidity to theupstanding posts 20 posts and automatic positioning of the rebar. The first centeringsupport bracket 24 a can extend in a first direction proximate a peripheral edge of thebase 14. The second centeringsupport bracket 24 b can extend in a second direction proximate the peripheral edge of thebase 14. In one embodiment, the first centeringsupport bracket 24 a and the second centeringsupport bracket 24 b are positioned generally orthogonal to each other. - The centering
bracket support system 23 can also include a third centeringsupport bracket 24c that can also extend between each of theupstanding posts 20 and across support 19 to provide increased structural rigidity to theupstanding posts 20 and automatic centering of the rebar. In this embodiment, a length of the third centeringsupport bracket 24 c can be greater than a length of the first centeringsupport bracket 24 a and the second centeringsupport bracket 24 b. However, any configuration of length, size, or position of theupstanding posts 20,legs 21,base 14, cross supports 19 and centeringsupport brackets - Referring to
FIGS. 3 and 4 ,ribs 26 can extend from thelower surface 16 of the base 14 to provide additional support when the rebar is positioned thereon. Theribs 26 can be positioned on the cross supports 19 or on the cross supports 19 and portions of the base 14 extending around a perimeter of thebase 14. In one example embodiment, as illustrated inFIGS. 3 and 4 , each of theribs 26 is connected to and extends between aleg 21 and acentral post 27 that extends from thelower surface 16 of thebase 14. The use of the centeringsupport brackets 24 and theribs 26 provide increased structural rigidity to theupstanding posts 20, legs andbase 14 such that installers are able to walk on installed support chairs 12 and rebar without fear of shifting the rebar or breaking the support chairs 12. - Referring to
FIGS. 7-9 , thesupport plate 30 includes a generallyplanar panel 32 having a configuration of a rectangle or square. In one embodiment of the invention, thepanel 32 will have the same footprint or area as the base 14 such that when the two are connected together the base 14 is position generally parallel over thepanel 32. Thepanel 32 can be constructed with the same generally rigid material as thesupport chair 12. The thickness of thepanel 32 can vary depending upon the amount of support needed during use. - The
panel 32 can include a plurality ofpegs 34 extending from itsupper surface 35 for receiving and support thelegs 21. Each of thepegs 34 includes abore 36 extending therein having a size and shaped to receive each of thelegs 21. Thelegs 21 and theupstanding posts 20 or thelegs 20 and thepegs 34 can be loosely fitted together to ensure easy assembly and disassembly or they can be tightly fitted together to ensure that they will not become disconnected during use. In another embodiment, thelegs 20 and thepegs 34 can be fixed together such that thesupport chair 12 and thesupport plate 30 are one unit. - Referring to
FIGS. 7-9 , each of thepegs 34 can include a support bracket orgusset 38 extending between and coupled to thepegs 34 and theupper surface 35 of thepanel 32 to provide structural rigidity to thelegs 21 when they are connected to thesupport plate 30. Each pair ofsupport brackets 38 extending from each peg 34 includes long axes that intersect in a center of thepegs 34 such that a pair ofcorresponding support brackets 38 of each peg 34 is generally oriented orthogonally to each other. Additionally, as particularly illustrated inFIGS. 7 and 9 , thesupport brackets 38 of thepegs 34 are disposed proximate a lateral or peripheral edge of thepanel 32 such that eachsupport bracket 38 of thepegs 34 lies in a plane generally parallel to a plane of one of the perimeter edges of thepanel 32. - In use, the installer decides if the
support chair 12 needs to be connected to thesupport plate 30. If needed, the installer inserts thelegs 21 of thesupport chair 12 into thebores 36 of each of thepegs 34 on thesupport plate 30. Once thesupport chair 12 and thesupport plate 30 are connected the installer lines them in the form where the concrete will be poured. Once in position, the installer lays rebar or other construction material on to the support chairs 12. The V-shape formed by thesupport brackets 24 extending between each of theupstanding posts 20 and theupper surface 15 of the base 14 cause each rebar to automatically find a center of thesupport chair 12 between theposts 20 and thelegs 21. The installer can also install rebar on the support chairs 12 such that they cross each other or such that a long axis of each of the rebar intersect each other at a center of thesupport chair 12. - In some uses, where a thicker layer of concrete is needed, there is a need to have multiple layers of rebar. During this use the installer inserts the
legs 21 of additional support chairs 12 into thesockets 22 of the upstanding posts 20. The installer is then able to lay pieces of rebar on top of the new layer of support chairs 12. These steps can be repeated until the desired number of rebar in place. Once all of the support chairs 12 and the rebar are in place, the installer is able to pour the concrete. The concrete then flows around the support chairs 12, through theholes 18, between theupstanding posts 20 and thelegs 21, and over thesupport plate 30, thereby ensuring that they are fixed in place. The orientation and number ofsupport brackets 24 and 28 extending between theupstanding posts 20 and thebase 14 and between thepegs 34 and thepanel 32 ensure that the lower support chairs 12 do not buckle or break under the weight of the rebar and concrete. - The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
