Problems solved by technology

When pouring concrete, according to the division of the construction section, the formwork is usually supported to the structural slab, the concrete is poured on the slab, and then the column formwork is supported, and the construction of the next construction section is carried out, so that it is easy to form a wrong platform at the floor, resulting in The flatness of the shear wall in the stairwell cannot meet the specification requirements

Embodiment Construction

[0031] The embodiments of the present invention are further described below in conjunction with the accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this:

[0032] Such as figure 1 as shown, figure 1 Shown is the situation that the present invention is used in the construction of the shear wall in the stairwell of a high-rise building. In the figure, the shear wall in the stairwell is supported by multi-layer wooden formwork, the inner formwork 5 in the stairwell is integrally supported, and the outer formwork 3 is set up to the elevation of the floor slab. The length of the multi-layer wood formwork is 1830mm, the width of the multi-layer wood formwork is 915mm, and the thickness of the multi-layer wood formwork is 15mm.

[0033] The stairwell shear wall of the present invention supports formwork twice and pours twice, with stairwell shear wall reinforcement binding, s...

Abstract

The invention provides a construction method of a shear wall of a staircase through one-time formwork erecting and two-time pouring. The method comprises the following steps that formworks are manufactured according to the size of the shear wall of the staircase, and the formwork erecting height of one-time formwork erecting and two-time pouring exceeds the construction height of a structure layer, and reaches the bottoms of a beam and a plate of a rest platform of the upper layer of the structural construction layer for formwork matching; then, according to the height of floors, formwork arrangement of the next construction segment is conducted, an erecting upper port of the formwork of the shear wall of the last construction segment is used as the basis of next-time formwork erecting, the process is conducted step by step, the sides, close to the staircase, of the formworks of the shear wall are continuously arranged from bottom to top, two-layer formworks are arranged on membranes of the shear wall close to the staircase during construction, and other formworks are erected according to a traditional method. The construction method has the advantages that the principle is simple,the operation is conducted conveniently, the common quality problem of staggering tables of the staircase is solved, and a certain economic benefit and a certain social benefit are achieved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and construction methods, and in particular relates to a construction method for a stairwell shear wall with one-time formwork support and two-time pouring. Background technique [0002] In the process of stair construction, the stair and the structural slab are usually divided into the same construction section. When pouring concrete, according to the division of the construction section, the formwork is usually supported to the structural slab, the concrete is poured on the slab, and then the column formwork is supported, and the construction of the next construction section is carried out, so that it is easy to form a wrong platform at the floor, resulting in The flatness of the shear wall in the stairwell cannot meet the specification requirements. Contents of the invention [0003] The problem to be solved by the present invention is to provide a construction method; espec...
