Auxiliary adjusting device for assembling type prefabricated stair installation

Abstract

The invention discloses an auxiliary adjusting device for assembling type prefabricated stair installation, and relates to the technical field of building construction. The problems that in a hoistingprocess of an existing prefabricated stair, a steel wire rope is generally adopted for hoisting, certain potential safety hazards exist during the hoisting, the hoisting stability is poorer, and meanwhile, when inclination adjustment is conducted on the stair, the accuracy of the inclination angle is hard to guarantee, and the installation operation is convenient is solved. The auxiliary adjusting device comprises a lifting support frame, the front portion and the rear portion of the lower portion of the hoisting supporting frame are connected to angle adjusting supporting rods through hinges, the front portion and the rear portion inside the hoisting supporting frame are each rotationally connected to angle adjusting driving lead screws, and the left side and the right side of the angleadjusting supporting rods are slidably connected with hoisting sliding blocks. According to the auxiliary adjusting device for the assembling type prefabricated stair installation, the lifting safetyis higher, meanwhile, the installation angle of the stair can be finely adjusted, the angle of the stair can be accurately controlled, it is guaranteed that the angles of the two sides of the stair are uniform, better conditions are provided for stair construction, use is easy, and operation is convenient.

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
