Quick template supporting construction method of elevator shaft

Abstract

The invention discloses a quick template supporting construction method of an elevator shaft. Firstly, a supporting frame which comprises a bottom stretcher, middle vertical posts and a top workbench is constructed in the bottom of the elevator shaft; the top workbench is matched with the elevator shaft in size; the lower end of the bottom stretcher is butted on an elevator door; the upper end is built on an elevator shaft wall which is opposite to the elevator door; the upper ends of the middle vertical posts are articulated together with the bottom surface of the top workbench; the lower end of one group of the middle vertical posts is articulated together with the upper stretcher body of the bottom stretcher; the lower end of the other group of the middle vertical posts is clamped on the bottom stretcher; then, an inner and an outer wall templates and an outer scaffold are constructed on the top workbench for casting the elevator shaft wall; after one layer of elevator shaft is cast, the inner wall template is moved inwards to leave a wall surface; the outer wall template is removed; the supporting frame is integrally lifted upwardly by one layer by vertical lifting equipment; then, the inner wall template is moved outwardly to be near the wall surface; the outer wall template is repeatedly constructed; and the casting of a previous elevator shaft wall is finished.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a construction method for an elevator shaft, in particular to a rapid formwork construction method for the elevator shaft. Background technique [0002] In the construction process of high-rise buildings, the elevator shaft construction methods currently used are relatively complicated. The concrete pouring of the walls, columns, and beams of the elevator shaft requires a large number of formwork for support. All the templates and supporting frames used are removed and taken out. When pouring the upper layer of the elevator shaft, another frame is built and the template is installed. This process needs to be repeated continuously throughout the construction process of the high-rise building.

Problems solved by technology

[0002] In the process of high-rise building construction, the elevator shaft construction methods currently used are relatively complicated. The concrete pouring of the walls, columns, and beams of the elevator shaft requires a large number of formwork for support. All the templates and supporting frames used are removed and taken out. When pouring the elevator shaft on the upper floor, another frame and template are installed. This process needs to be repeated continuously throughout the construction process of high-rise buildings.

This construction in a special environment such as an elevator shaft with narrow construction space, high depth, few fixed points, and difficulty in sweeping frame and formwork is not only very cumbersome, but also time-consuming and labor-intensive, resulting in high construction costs and labor-intensive workers. Big, inconvenient to operate, unsafe to work with
