Prefabricated composite floor component

Abstract

The invention discloses a prefabricated composite floor component which comprises high-precision dismounting-free form boards, combined formed steel bar products and connecting screws. The bottom faceof a floor is formed by the multiple high-precision dismounting-free form boards, rectangular grooves are adopted by the single faces of the high-precision dismounting-free form boards to achieve galling, the combined formed steel bar products are placed above the bottom face of the floor and are connected together through n-shaped profile steel, the open sides of the n-shaped profile steel are connected to the bottom faces of the combined formed steel bar products, concrete is poured after the closed sides of the n-shaped profile steel are connected with the galling faces of the rectangulargrooves of the floor through connecting screws, and a prefabricated is formed. Reserved wire box wire pipes are arranged on the high-precision dismounting-free form boards and in the combined formed steel bar products. According to the prefabricated composite floor component, the concept is ingenious, the structure is compact and reasonable, prefabricated parts are thin and light, lifting and transporting are facilitated, cost is reduced, by means of the design of the dismounting-free form boards, workloads are reduced, and the requirement for high levelness of a combined beam is guaranteed.

Description

technical field [0001] The invention relates to the field of assembled concrete structure buildings, in particular to an assembled prefabricated composite floor component. Background technique [0002] In prefabricated concrete structure buildings, prefabricated laminated floors are often used as horizontal load-bearing components. The prefabricated laminated floor is a formwork-free floor. The thickness of the prefabricated part is generally 6 cm. It is poured after hoisting and installation. The post-cast concrete is effectively laminated with the precast part, and the thickness of the post-cast part is generally 7 cm. Prefabricated laminated floor slabs are heavy, difficult to transport and hoist, and costly. In addition, the survival thickness of the prefabricated laminated floor slab is generally 13 cm, which is about 3 cm thicker than the traditional cast-in-place floor slab, which affects the net height of the floor. Therefore, how to develop a novel floor slab to r...
