A floor assembly is provided. The floor assembly is configured to form or be positioned on a floor of an enclosed space. The floor assembly includes a grid, a pan, and a surround member. The grid has an array of openings configured to allow passage of liquid. The pan is disposed beneath the grid and defines a cavity. The pan includes a pan floor and a frame. The frame is disposed laterally outward of the pan floor and supports the grid. The surround member is supported by the frame. The surround member is disposed laterally outward of the grid, and the surround member and grid do not overlap.

A supporting element for cylindrical or column-shaped elements of modular elements for making raised and/or ventilated floors, includes a substantially plane base configured to be rested on the underlying floor, two or more lateral extensions arranged at sides of the plane base and coplanar with the plane base, coupling elements arranged on the portions of said lateral extensions that are far from the plane base. The supporting element includes a first series of projections arranged along a circle centered on the plane base, defining a seat in which a lower end of the cylindrical or column-shaped elements is inserted and housed, and wherein the projections of the first series are configured to adhere to the surface of the cylindrical or column-shaped element housed in the seat.

A double-shelled load-bearing structure module of any geometric shape, is formed from top and bottom secondary shell elements. A double-shelled load-bearing structure in the form of a primary shell structure is joined with the module, made of individual assembled load-bearing structure modules of this kind having statically necessary filling rods. The secondary shell elements have, in each corner, a connection pocket, which is open at the top or bottom or is open at the top and bottom, of appropriate size for connecting a plurality of load-bearing structure modules. The connection pocket, at least on the outside, on the outer vertical surfaces of the secondary shell elements, is delimited by preferably metal profiles or metal sheet. Connection tabs can also be disposed in each corner instead of connection pockets. The connection tabs are formed from angular surfaces, preferably metal sheet, protruding towards the intermediate space between the secondary shell elements.

An anchor assembly for riser pipes uses a plate and sleeve to support a stub pipe which penetrates a floor of a structure, such as a building, in which the riser is located. Studs extending from the plate and the sleeve engage the floor and enhance the local structural strength of the floor. A bracket which engages the plate is used to mount the stub pipe within the sleeve. The riser pipe elements are attached to the ends of the stub pipe. Fire insulation material is positioned between the stub pipe and the sleeve.

An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.

Disclosed is a modular building system including, in some embodiments, one or more wall panels, one or more floor panels, and one or more roof panels. The modular building components of the modular building system including the one or more wall panels, the one or more floor panels, and the one or more roof panels can form housing or storage structures with electrical wiring, plumbing, or both wiring and plumbing. The housing or storage structures can be erected by one or more persons without a need for a plumber, an electrician, or power tools. Also disclosed is a method for erecting one or more housing or storage structure in accordance with the modular building system.

A sleeve assembly for poured concrete decks has a tubular sleeve connected to a base flange by stiffeners or an optional base wall. An intumescent ring and fire ring plate are fastened to the base flange. The stiffeners and optional base wall are configured so concrete passes between the stiffeners to entrain a fire ring plate and ring of intumescent material in the concrete by passing through a gap between the base wall and the sleeve or through open windows in the base wall to entrain the base wall when it is present.
