Problems solved by technology

[0003] The reinforced concrete shear walls built in the prior art are thicker and occupy a larger area. At the same time, air bubbles will be generated on the surface and inside, resulting in poor pouring quality. Therefore, we propose a thin-walled reinforced concrete shear wall. Construction method for solving the above problems

Abstract

The invention discloses a construction method of a thin-walled steel concrete shear wall. The construction method comprises the following steps that S1, a foundation is dug firstly and then compacted, and the original foundation is backfilled with concrete of 40 cm after compaction; S2, then the size of the constructed reinforced concrete shear wall is measured; S3, a scaffold is constructed according to the measured size; S4, then formworks are laid on the outer side of a support and fixed; S5, then reinforcing steel bars are used for fixing; S6, shear wall concrete is poured on the basis of the step S5; and S7, after pouring is completed, the formworks are vibrated to remove bubbles in the shear wall. According to the construction method, the strength of the shear wall is enhanced by reinforcing raw materials of the shear wall, and thus the thickness of the shear wall can be decreased; and meanwhile, after pouring is completed, the formworks are vibrated to remove the bubbles in the shear wall, thus the strength of the shear wall is enhanced, the service life is greatly prolonged, and the construction method is suggested to be popularized energetically.

Description

technical field [0001] The invention relates to the technical field of steel-concrete scissor walls, in particular to a construction method for thin-walled steel-concrete shear walls. Background technique [0002] Reinforced concrete shear wall refers to the piece of reinforced concrete wall set in the building structure with the main purpose of bearing horizontal load (and also bears the vertical load within the corresponding range); in high-rise and super high-rise building structures, horizontal The load will play a major role, and the house needs a large anti-sway capability; the anti-sway capability of the frame structure is weak, and the hybrid structure is only used in multi-storey buildings due to the low strength of the wall material and its own weight, so it is used in high-rise and In the super high-rise building structure, a new structural system needs to be adopted, which is the shear wall structure system; the shear wall can be divided into reinforced concrete ...
