A shear wall with integrated section steel as the skeleton and its on-site construction method

Abstract

The invention discloses a shear wall with integrated section steel as a skeleton and an on-site construction method. The shear wall includes: an integrated section steel module as the skeleton of the whole wall body and its inner cavity as a main pouring cavity for pouring concrete; The formwork is detachably arranged on the periphery of the integrated steel module at intervals through the spacing components, and an auxiliary pouring cavity for pouring concrete is formed between the pouring formwork and the outer wall of the integrated steel module; the outer wall of the integrated steel module is provided with There are several grout holes connecting the main pouring cavity with the auxiliary pouring cavity and several threading holes for setting threading pipes, and the auxiliary pouring cavity is provided with a reinforcing mesh. On the premise of ensuring the tensile and compressive properties of the wall, the above-mentioned shear wall with integrated section steel as the skeleton is not only convenient for construction and later decoration, reduces the amount of steel used, and has low cost; it also has good fire protection, anti-corrosion and heat insulation properties. .

Description

Technical field [0001] The present invention relates to an integrated steel residential construction technique, in particular, involving a shear wall and on-site construction method with integrated steel as a skeleton. Background technique [0002] The own advantages of integrated steel residential products have been recognized in the construction process, with broad application prospects. At present, existing integrated steel residential products are generally universally shortcoming in specific construction processes: [0003] 1) The concrete and steel pipe binding are completely dependent on the pushing effect, the steel pipe is at the end, and since the steel and concrete is different from the difference in thermal shrinkage coefficients, once the strength of the force, the strength of the force is weakened, it will affect the pressure-resistant load of the entire system, and tensile Force, it is easy to form a shell with concrete, affecting structural power; [0004] 2) The ...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a shear wall with integrated section steel as the skeleton, so as to solve the existing problems of integrated section steel houses in the prior art that the steel pipe bundles are easily peeled off from the concrete, poor fireproof and anti-corrosion performance, poor thermal insulation effect and use. The problem of large amount of steel

[0010] Another object of the present invention is to provide a method for on-site construction of a shear wall with integrated section steel as the skeleton, so as to solve the problem of poor overall structural strength in the construction process of integrated section steel houses in the prior art, and the need for anti-corrosion and fire prevention treatment in the later stage. The problem of large amount of steel
