Environment-friendly concrete composite floor slab

Abstract

The invention provides an environment-friendly concrete composite floor slab. The environment-friendly concrete composite floor slab is characterized in that the environment-friendly concrete composite floor slab comprises a connecting steel bar support, a bottom plate steel bar support, four connecting steel bars, a bottom plate steel bar, a tie steel bar, a top steel bar, anti-shearing keys, anouter frame, positioning steel bars, positioning pipes, stirrups and a bottom plate steel bar casing pipe; outer frame connecting holes are formed in the two ends of the outer frame, outer frame positioning holes are formed in the two sides of the outer frame, and the anti-shearing keys are arranged on the inner sides of the connecting steel bars and the bottom plate steel bar; the bottom plate steel bar and the upper sides and the lower sides of the connecting steel bars are subjected to concrete pouring to form composite floor slab concrete layers; the positioning pipes penetrate into the space between the composite floor slab concrete layers through the positioning steel bars for fixed connection; the stirrups are arranged on the outer sides of the top ends of the four connecting steelbars in an embracing mode and fixedly connected with the connecting steel bars. Distributed bars in the composite floor slab are distributed evenly, the steel bars are aligned accurately, the structure is simple, the manufacturing process is easy and convenient, manufacturing is easy, the structure strength is high, and construction and mounting are easy.

Description

technical field [0001] The invention belongs to the field of prefabricated concrete buildings, in particular to a green and environment-friendly concrete laminated floor slab. Background technique [0002] The laminated slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. The laminated floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for decoration of the facing layer, and is suitable for high-rise buildings and large-bay buildings that require high overall rigidity. The prestressed main reinforcement of the thin slab is the main reinforcement of the laminated floor, and the upper concrete cast-in-place layer is only equipped with negative moment reinforcement and structural reinforcement. The prestressed slab is used as the bottom form for the cast-in-place concrete course, and it is not necessary to support the formwork for the cast-in-place ...

AI Technical Summary

Problems solved by technology

[0003] There are many types of laminated slabs in the existing technologies, and the structural forms of the laminated floors are also relatively diverse. The laminated floors in the prior art have the following technical defects: the manufacturing process of the existing laminated floors is complicated, and the existing technology center stacks The splicing and alignment between the laminated slabs and the laminated slabs is not accurate enough, which causes difficulties in the actual construction and installation process. Now there is a need for a laminated floor slab that has high structural strength, is easy to manufacture, and can ensure accurate splicing between laminated slabs
