- 1. Field of the Invention
- The present patent application concerns building components, and, more specifically, a plugging and connecting element for modular floor construction.
- 2. Description of Related Art
- Modular elements for the construction of raised or aerated floors are generally dome-shaped and have an upper surface supported by four or more legs divided by arch-shaped openings. These modular elements are juxtaposed and connected to each other to produce a continuous grid structure. Reinforcing iron rods, such as an electro-welded net or ribbed bars, are positioned over such grid structure, and concrete is then poured. It is then possible to obtain a monolithic floor slab, aerated in the lower part and suitable for inserting pipes, ducts, cables and similar building components within the aerated space.
- These modular elements have modular dimensions and, once installed, fill a surface determined by multiples of the modular dimension.
- Often, the floors to be produced have surface dimensions that are not precise multiples of the modular elements, leaving one or more floor strips uncovered. Connecting elements to fill the uncovered area are known in the prior art and are shaped substantially like a box with an open side. Because of their configuration, these connecting elements cannot carry the weight of a person, so are not suited for walking on. Further, the connecting elements in the prior art are affixed to the modular elements by means of deep lateral notches, preventing their ability to slide and to be adjusted in position in the event they are too wide or too narrow for the application at hand.
- Other connecting elements in the prior art consist of blocks of expanded material, typically expanded polystyrene, having a square or rectangular base and lateral walls connected to an upper arch-shaped surface matching the arch-shaped openings of the modular elements. A connecting element of this type is inserted inside an arch-shaped opening of the last modular elements in order to achieve complete coverage of the floor surface.
- The above described connecting elements are preferably positioned in a central area of the floor, that is, modular elements are placed in positions starting from the floor edges and are the then joined with the connecting elements in the middle of the floor.
- Other types of connecting and plugging elements are also known in the prior art, and are generally manufactured with expanded materials generating high storage volumes, material requirements, and costs. Further, these connecting and plugging elements typically have smooth surfaces and no means for connecting to each other during positioning and/or during the pouring of the concrete, therefore, these connecting and plugging elements can slide during application making them totally or partially useless.
- A connecting and plugging element for modular floor construction is provided comprising a linear element having a substantially U-shaped cross section defined by two lateral walls connected by an arched surface, and further having two head walls each connecting the two lateral walls on opposing sides of the linear element. The connecting and plugging element is preferably made of a thermoplastic material, and the two lateral walls and one of the head walls may have free edges that extend to form an enlarged bearing base with holes for connecting to the floor base and also with couplers or relieves for connecting to reinforcing bars or to adjacent connecting and plugging elements.
- It is an object of the present invention to provide a connecting element to be used in the manufacture of aerated or elevated floors that plugs the arch-shaped openings of the modular elements and does not slide while the formwork is being or during pouring of the concrete.
- It is another object of the present invention to provide a connecting element to be used in the manufacture of aerated or elevated floors, on which operators can walk safely.
- These and other advantages of the present invention will become apparent from a reading of the following description, and may be realized by means of the instrumentalities and combinations particularly pointed out in the appended claims.
- The drawings constitute a part of this specification and include exemplary embodiments of the invention, which may be embodied in various forms. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged to facilitate an understanding of the invention.

- Turning now to
FIGS. 1-2 , a connecting and plugging element (P) comprises a linear element with a substantially U-shaped cross-section, matching the shape of the arch-shaped opening of a modular element (M). The linear elements has two lateral walls (P1) and an arched surface (P2) connecting the two lateral walls, the lateral walls (P1) being typically inclined while the arched surface (P2) has a shape corresponding to the opening in modular elements (M). The lateral walls (P1) are connected, on opposing sides, by head walls (P3) that are substantially vertical. Connecting and plugging element (P) made be manufactured from a thermoplastic material. - The free edges of connecting and plugging element (P) may have extensions (P4) protruding outwards laterally in a horizontal direction, so as to form an enlarged bearing base.
- In one embodiment, extensions (P4) of the free edges are present on three sides of connecting and plugging elements (P), that is, on lateral walls (P1) and one head wall (P3), while there is no extension on the opposite head wall (P3).
- Various holes (P4 f) may be present on extensions (P4), in order to enable the affixing of connecting and plugging element (P) to the lower floor slab. Moreover, on extension (P4) of one head wall, relieves or couplers (P4 a) may be present of a shape suitable for securing connecting and plugging element (P) to one or more concrete reinforcing bars, in order to prevent connecting and plugging element (P) from sliding toward the inside of modular element (M). On head walls (P3), on arched surface (P2) and/or on lateral walls (P1), stiffening ribs (Pa) may be present, in order to provide connecting and plugging element (P) with sufficient mechanical strength to withstand the weight of a walking person.
- Connecting and plugging element (P) is suitable for positioning on a lower floor slab and, because of its shape and mechanical properties, and because it can be prevented from sliding sideways, connecting and plugging element (P) performs its function in a variety of situations that occur in the manufacture of aerated or elevated floors of dimensions different from entire multiples of modular elements (M).
- Connecting and plugging element (P) needs only inserting in the arch-shaped hole of the last modular element (M) of the floor grid, so to extend to the edge of the floor.
-
FIG. 3 illustrates an application of connecting and plugging element (P) when a foundation wall is present. If that situation, connecting and plugging element (P) may be positioned against the foundation wall, with the edge of head wall (P3) that is extension-free abutting against the foundation wall. -
FIGS. 4-4 a show an application of connecting and plugging element (P) in conjunction with reinforcing bars (Ar) that are used to produce beams of the same thickness as the floor. If the beam has not been poured yet, when beams and floor slab are poured at the same time, connecting and plugging element (P) may be positioned so to have the couplers (P4 a) on extension (P4) of head wall (P3) mate with reinforcement bars (Ar). - Connecting and plugging element (P) may also be positioned between two modular elements (M) in different areas of the floor surface, so to connect two modular elements (M) that are spaced apart.
-
FIG. 5 shows three aligned connecting and plugging elements (P), positioned with their heads walls next to each other and having the extension-free edge of the head wall of one element secured to couplers (P4 a) on the extension of the head wall of the adjacent element. - While the invention has been described in connection with the above described embodiment, it is not intended to limit the scope of the invention to the particular forms set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the scope of the invention.
