Auxiliary adjustment device for installation of prefabricated stairs

Abstract

The invention discloses an auxiliary adjusting device for the installation of prefabricated prefabricated stairs, relates to the technical field of building construction, and solves the problem that the existing prefabricated stairs generally use steel wire ropes for hoisting during the hoisting process, and there are certain safety hazards during hoisting. The hoisting stability is poor, and at the same time, when adjusting the inclination of the stairs, it is difficult to ensure the accuracy of the inclination angle, and the installation and operation are inconvenient, including the hoisting support frame; the lower part of the hoisting support frame is hinged at the front and back. A support rod; a set of angle adjustment drive screws are rotatably connected to the front and rear of the hoisting support frame; a set of hoisting sliding blocks are slidably connected to the left and right sides of the angle adjustment support rod. The invention has higher hoisting safety, can finely adjust the installation angle of the stairs, can precisely control the angle of the stairs, ensure that the angles on both sides of the stairs are uniform, provide good conditions for the construction of the stairs, and is simple to use and easy to operate.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an auxiliary adjusting device for the installation of prefabricated prefabricated stairs. Background technique [0002] Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and fabricated, and transported to the construction site. Reliable connection method The prefabricated staircase is an important component of the building assembled and installed on site. When installing the prefabricated staircase, the prefabricated staircase needs to be hoisted in place first, and then fixed and grouted. [0003] For example, the application number: CN201310353010.9 is a prefabricated suspended wooden staircase, which belongs to the technical field of housing construction. It includes s...

Problems solved by technology

[0005] The purpose of the present invention is to provide an auxiliary adjustment device for the installation of prefabricated stairs, to solve the problem that the existing prefabricated stairs proposed in the background technology generally use steel wire ropes for hoisting during the hoisting process, and when hoisting, the prefabricated stairs are horizontal Placement, the stairs need to be placed on an incline during installation. During the hoisting process, the steel wire rope is in an inclining state, which has certain safety hazards, and the hoisting stability is poor. At the same time, it is difficult to ensure the accuracy of the inclination angle when adjusting the inclination of the stairs. Sex, the problem of inconvenient installation and operation
