Construction method of steel structure formwork-free self-insulation floor slab

Abstract

The construction method is characterized in that steel beams, a main beam and secondary ridges are included, the steel beams comprise upper wing plates, lower wing plates and webs, the upper wing plates and the lower wing plates are parallel, the webs are perpendicularly connected between the upper wing plates and the lower wing plates, the main beam is arranged between the steel beams, the two ends of the main beam are arranged on the lower wing plates of the steel beams, and the secondary ridges are arranged on the main beam; and a heat-preservation non-dismantling formwork or a heat-preservation laminated plate is laid on the secondary ridges, steel bars are arranged on the heat-preservation non-dismantling formwork or the heat-preservation laminated plate, and then concrete is poured. The construction progress is accelerated, the floor does not need to be additionally provided with a heat preservation layer, and heat preservation and structure integration is achieved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building slabs, and in particular relates to a construction method for steel structure formwork-free self-insulating slabs. Background technique [0002] Steel structure building is a new type of building system. At present, the application of steel in high-rise buildings is becoming more and more mature, and it has gradually become the mainstream construction technology. Steel structure buildings have the following advantages: it can greatly save construction time, and construction is not affected by seasons; it can increase the use of residential space, reduce construction waste and environmental pollution; building materials can be reused, driving the development of other new building materials industries; earthquake resistance Well, it is easy to transform, flexible and convenient in use, and brings comfort to people, etc., so it has been more and more widely used. One type of floor sla...

AI Technical Summary

Problems solved by technology

[0003] The defect of this technical scheme is: First, the steel plate at the bottom end of the reinforced truss floor deck cannot be disassembled and cannot be reused, and a large amount of steel plates are consumed

[0005] The defect of this technical solution is that the floor needs to be insulated

[0007] The prior art solutions mentioned above have the following defects: First, during the floor slab assembly process, the floor slab usually needs to be hoisted for installation. This solution needs to first insert the adjacent two side edges of the floor slab into a pair of adjacent first I-beams. on the lower flange of the floor, and then slowly lower the edges of the other two sides of the floor to directly fall on the upper flanges of the corresponding two second I-beams. The floor needs to be adjusted more in the air before the floor can be installed , making the slab installation process slower

[0009] The disadvantages of this technical solution are, firstly, the concrete laminated slab has a large area, is heavy, has high hoisting costs, and is time-consuming and laborious to operate.

Second, the site needs to be equipped with a special transport channel for large trailers, the turning radius must be large, there must be a special load-bearing stockyard, and the roof of the basement needs to be specially strengthened.
