Semi-fabricated concrete floor

Abstract

The semi-fabricated concrete floor mainly comprises a finished reinforced concrete bottom plate, a silk screen, a finished reinforcing mesh, an inner concave round opening, a reinforcing steel bar drag hook, a post-cast reinforced concrete top plate, an upper reinforcing mesh, an inserting reinforcing steel bar, a connecting reinforcing steel bar and a connecting plate. The bottom layer structure of the semi-fabricated concrete floor slab is formed by splicing a plurality of finished reinforced concrete bottom plates and connecting plates; the upper layer structure of the semi-fabricated concrete floor slab is a post-cast reinforced concrete top plate; a finished reinforcing mesh is arranged in the middle of the finished reinforced concrete bottom plate; a concave round opening is formed in the upper surface of the finished reinforced concrete bottom plate; during application, the finished reinforced concrete bottom plates and the connecting plates are combined and spliced on a formwork on the side edge of a beam, all the finished reinforced concrete bottom plates are connected together through the inserting reinforcing steel bars and the connecting reinforcing steel bars, then the upper-layer reinforcing steel bar net is arranged on the upper sides of the finished reinforced concrete bottom plates, and finally concrete is poured on the upper-layer reinforcing steel bar net. Therefore, the construction work of the semi-fabricated concrete floor slab can be completed.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and relates to a semi-assembled concrete floor slab. Background technique [0002] Traditional building slabs are generally constructed by first supporting the formwork, arranging steel bars, and finally pouring concrete. Although the strength of the constructed concrete slab is relatively high, it has poor thermal insulation performance, long construction period, loud construction noise, and resulting buildings. Excessive waste, serious pollution, and high construction costs. Modern prefabricated buildings have shortcomings during construction: difficult transportation, excessively large components, difficult hoisting, and high construction costs. In view of the above-mentioned problems, the present invention provides a semi-fabricated concrete floor slab, the technical features of which are: reducing formwork links, reducing construction costs, simple hoisting, improving build...

AI Technical Summary

Problems solved by technology

[0002] When constructing traditional building slabs, the formwork is usually set up first, then the steel bars are arranged, and finally the concrete is poured in. Although the concrete slabs constructed in this way have relatively high strength, they have poor thermal insulation performance, long construction period, large construction noise, and building problems. Disadvantages such as excessive garbage, serious pollution, and high construction costs

Modern prefabricated buildings have disadvantages during construction: difficult transportation, oversized components, difficult hoisting, and high construction costs.
