Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

System for fixing to the ground walls of a building includes a plurality of supporting elements interposed between a concrete foundation of the building and the walls, connecting elements for connecting at least two supporting elements that are aligned on one another, adjusting elements for adjusting a distance of the supporting elements from the foundation and for correcting a possible tilt of the supporting elements with respect to a horizontal reference plane, anchoring elements for anchoring the supporting elements to the foundation, the supporting elements being made of plastics.

Systems and methods for supporting a concrete slab are disclosed. The disclosed systems and methods may comprise an array of coupled hollow boxes to support a concrete slab monolithically poured on the array. The array of hollow boxes may be particularly suited for supporting a concrete slab to be emplaced at a construction site on expansive, collapsible, compressible, and/or rocky soils. The disclosed systems and methods may be more economically feasible and more reliable than other methods of preventing damage to a concrete slab in an expansive soil setting.

Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

A concrete ceiling has a lower reinforcing mesh and an upper reinforcing mesh between which a plurality of displacement bodies are arranged, wherein the lower and upper reinforcing mesh and the displacement bodies are embedded in concrete and each displacement body at least partially surrounds at least one channel which establishes a connection between the concrete at the lower reinforcing mesh and the concrete at the upper reinforcing mesh.

A floor construction on a subsurface has a screed with a reinforcement made of a 3D textile with a lower and an upper textile ply which are connected together by one or more pile threads, wherein the lower textile ply is arranged in the lower half of the screed and the upper textile ply is arranged in the upper half of the screed, wherein an insulation layer is preferably furthermore arranged between the subsurface and the screed. The reinforced screed of the floor construction allows thin screed layers with good load-bearing capacity. Good footfall sound insulation can be achieved with the floor construction containing an insulation layer.

A slab filler, and method for implementing fillers in a two-way concrete slab for building structures, are disclosed. The filler comprises an upper keeper tray and a lower keeper tray, and a volumetric filling element. The upper keeper tray is attached to a top of the volumetric filling element and the lower keeper tray is attached to a bottom of the volumetric filling element. The filler comprises a plurality of indicators positioned on all corners of the keeper tray to indicate an amount or level of a concrete fed on the filler. The filler further comprises grooves at an end of the spacer, configured to securely hold one or more belts. Spacers and belts are configured to receive one or more rebar. Further, the volumetric filling element is a high-density material, where the filler is incorporated without upper keeper tray and lower keeper tray.

A support for installing facing materials such as ceramic tiles on a substrate, such as, floors, walls and ceilings. The support plate has a plurality of spaced apart raised portions and recesses in the plate material, and a plurality of openings extending through the top surface and bottom surface of the plate material. The openings exposing a mat layer attached to the bottom of the support plate. Support plates of the invention are used for tile installations between a substrate and tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the openings forming a continuous bond between the mortar, openings and mat layer to provide a strong bond between the support plate, mortar and the tiles.

A support for installing facing materials such as ceramic tiles on a substrate such as floors, walls and ceilings wherein the support plate has a plurality of spaced apart recesses in the plate material, with the recesses being open at the top surface and have solid sidewalls and a base, and a plurality of slots in the non-recessed portions of the plate material extending through the top surface and bottom surface, the slots joining one or more adjacent recesses. The support plate of the invention is used for tile installations between the substrate and such tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the slots forming a continuous bond between the mortar and the adjacent slots providing for a strong bond between the support plate, mortar and the tiles.
