Cast-in-situ reinforced concrete hollow slab and construction method thereof

Abstract

The invention discloses a cast-in-situ reinforced-bar concrete hollow building slab and construction method, wherein the hollow building slab comprises a hollow internal mold with mounting frames provided with fastening grooves on the lower end, so as to fasten the spacer bars into the fastening grooves, and fasten the spacer bars with the bottom reinforced bars. The construction method consists of determining position of the hollow internal mold spacer bars, fixing the bottom reinforced bars onto the baffle plate, placing spacer bars onto the bottom reinforcing bars by means of the position of the hollow internal mold spacer bars, bonding the spacer bars with bottom reinforced bars, and finally fixing the hollow internal molds.

Description

Technical field: [0001] The invention relates to a cast-in-place reinforced concrete hollow slab, in particular to a reinforced concrete hollow slab manufactured by a hollow inner mold which can be integrated with a steel bar through an installation bracket, and also relates to a construction method of the hollow slab. Background technique: [0002] The cast-in-place reinforced concrete hollow slab is widely used in engineering structures because it reduces the amount of concrete and optimizes the slab structure. At present, the production of cast-in-place reinforced concrete hollow floors is mainly through setting hollow inner molds in the concrete. Its main function is to evacuate the concrete through the inner molds, reduce weight and save materials, improve the mechanical performance of the floor structure, and improve the use of the entire building. Function, with energy saving, environmental protection and other significant advantages. [0003] At present, an inner mo...

AI Technical Summary

Problems solved by technology

The main problem is that the positioning of the inner mold is not accurate, and the position of the inner mold is prone to shift; the second is that the components need to be connected and fixed during construction, and the work efficiency is low and the cost is high; the third is that the anti-floating ability of the inner mold is poor during the concrete pouring process
