The reinforced skeleton includes a number of truss strips arranged in an orderly manner. The front of each truss strip has a continuous wave-shaped equilateral triangle structure. The two outer sides of each truss strip are welded with vertical and horizontal steel bars to form a whole steel skeleton; In the bending part of the oblique bar, a block-shaped thermal insulation and sound insulation layer is placed between the reinforcement skeleton to form a board core, and the upper and lower layers of the reinforcement skeleton are poured with concrete and/or cementitious materials to form the upper and lower layers.

The purpose of this utility model can also be achieved through the following measures:

The steel skeleton is a grid structure, which is welded by a number of juxtaposed truss bars on its upper and lower outer sides; the truss bars are composed of three components: The rods are welded with steel bars to form a grid-like cavity to form an upper grid, and the lower chords are welded with steel bars to form a grid-like cavity to form a lower grid.

The upper and lower chords are monofilament and/or double-filament structures.

Diagonal wires are assembled and welded between the upper and lower grids of the steel mesh sheet.

The top view shape of the floor slab can be any one of strip shape, rectangle shape, circle shape, flat shape shape, polygon shape, and polygon shape.

The material of the thermal insulation layer is polystyrene board, polyurethane foam board, phenolic foam board, perlite, rock wool, slag wool, fly ash wool, glass wool, foamed concrete, and aerated concrete of any kind.

The utility model has the following positive and beneficial effects:

The composite floor slab of the utility model adopts a structure composed of a reinforced plastic core skeleton, a thermal insulation layer and an upper and lower layer. The truss strips are connected as a whole, and the upper and lower layers expose the bending parts of the truss strips. A heat insulation and sound insulation layer is placed in the skeleton cavity. Concrete or cementitious materials are poured around the skeleton to form a strip structure with upper and lower layers. This structure realizes light weight, large span, good anti-corrosion and fire-proof effects, and solves the problems of heat preservation and sound insulation of the floor slab. , but also factory prefabricated, fast construction, easy hoisting.
