Abstract

The invention discloses a construction method applied to a lifting platform in an elevator shaft in constructional engineering. The construction method includes the following steps that a workbench iserected in the elevator shaft, the length and the width of the workbench are set according to the length and the width of the elevator shaft, and a gap is reserved between the edge of the workbench and the side wall of the elevator shaft; a supporting bracket is erected at the bottom of the workbench, and the height of the supporting bracket is larger than that of a door opening of the elevator shaft; shear keys are mounted on the lower portion of the supporting bracket, long holes for mounting of the shear keys are formed in the lower portion of the supporting bracket, and after stretching out, the bottoms of the shear keys abut against the bottom face of the door opening of the elevator shaft; and a lifting drive device is mounted between the workbench and the bottom face of the door opening of the elevator shaft, the top of the lifting drive device is fixedly connected with the bottom of the workbench, the bottom of the lifting drive device abuts against the bottom face of the dooropening of the elevator shaft, and the lifting drive device drives the workbench and the supporting bracket to vertically move in the elevator shaft up and down through telescopic motion. By means ofthe lifting platform, the erecting and lifting efficiency of an operating platform is improved.

Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a construction method applied to an elevator shaft lifting platform in construction engineering. Background technique

[0002] In the building high-rise construction process, the formwork support of the four walls of the elevator shaft of each floor in the room mainly adopts the method of erecting an operation platform. At present, there are mainly the following construction methods for the formwork support operation platform on the inner wall of the indoor elevator shaft: the first layer of vertical poles are directly landed to build the frame body operation platform layer by layer to carry out the formwork support construction work; The formwork support construction work is carried out on the triangular steel frame platform through hoisting by tower crane equipment; the formwork support construction work is carried out on the lifting steel platform, etc.
