Supportless construction method for cast-in-place floor of high-rise steel structure house

Abstract

The invention relates to the field of template construction, in particular to a supportless construction method for a cast-in-place floor of a high-rise steel structure house. The supportless construction method for the cast-in-place floor of the high-rise steel structure house comprises the steps that a load on a supportless template is calculated according to the condition of an actual high-rise steel structure, and steel tubes and support rods are selected; multiple steel tubes are fixed between a pair of steel beams which are arranged in parallel through locking devices. Each steel tube and a pair of steel beams are vertically arranged. The locking devices are a pair of locking devices. The pair of locking devices clamp one ends of the steel tubes in the middle and limit one ends of the steel tubes in installing spaces of the steel beams. Multiple support rods are fixed above the multiple steel tubes. Two ends of each support rod are fixed in the installing space that a pair of steel beams and the other pair of steel beams are vertically arranged. A bottom die template is arranged above the multiple support rods and is fixed with two pairs of steel beams simultaneously. The supportless construction method for the cast-in-place floor of the high-rise steel structure house has the advantages that the construction period is shortened, safety hazards caused by template collapse due to instability of a scaffold are eradiated completely, at the same time, the construction cost is saved, and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of formwork construction, in particular to an unsupported construction method for a cast-in-place floor slab of a high-rise steel structure residence. Background technique [0002] Due to its light weight, low foundation cost, good seismic performance, suitable for weak foundations, easy installation, fast construction period, fast investment recovery, less environmental pollution during construction, reduction of overcapacity, and good seismic performance, steel structures are known as the second most comprehensive advantages. One of the "green buildings" of the eleventh century. At this stage, the floor slabs of the steel structure building system mainly adopt cast-in-place concrete structures. After the steel beams are installed, the floor slabs need to be erected full of scaffolding, and then formwork is supported, steel bars are bound, and concrete is poured. It is necessary to wait until the concrete reaches a c...

AI Technical Summary

Problems solved by technology

If the floor slab is not poured, the installation of the next steel column cannot be carried out, which directly affects the installation speed of the steel structure

[0003] In recent years, template collapse accidents have occurred frequently due to the instability of scaffolding. Due to the large number of scaffolds erected under the template, the probability of scaffold collapse is high. Once a collapse occurs, it is very difficult to carry out rescue.
