A construction method for installing and fixing prefabricated building components

Abstract

The invention relates to a construction method for installing and fixing prefabricated building parts, which includes a sling, a lateral displacement mechanism, a longitudinal displacement mechanism, a connecting mechanism and a limit mechanism. The bottom of the sling is connected with a lateral displacement mechanism, and There is a longitudinal displacement mechanism, the bottom of the longitudinal displacement mechanism is correspondingly equipped with a connecting mechanism, the side walls of the lateral displacement mechanism and the longitudinal displacement mechanism are equipped with limit mechanisms, the upper end surface of the first fixed shell is connected with the bottom of the sling, and the first fixed shell The bottom of the horizontal displacement groove is provided with a lateral displacement groove, and the first T-shaped connecting block is sleeved inside the lateral displacement groove. The first V-shaped roller shaft is installed on both ends of the top of the first T-shaped connected block, and the bottom of the first V-shaped roller shaft Cooperate with the installation of the first linear track, the first linear track is fixed inside the first fixed shell by bolts, the present invention can conveniently realize the precise hoisting of the prefabricated stairs, and has the characteristics of high safety performance and strong practicability.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a construction method for installing and fixing prefabricated building components. Background technique [0002] Prefabricated building parts are a general term for building accessories that are partially prepared in advance in a non-building environment. Among them, prefabricated stairs are one of them. Prefabricated stairs serve as elements for vertical circulation between floors. It is used for traffic connection between floors and when the height difference is large. Stairs should also be provided in multi-storey and high-rise buildings with elevators and escalators as the main vertical means of transportation. Although elevators are used as the main vertical means of transportation in high-rise buildings, stairs are still reserved for escape in case of fire. When installing the presupported stairs, they are all installed by hoisting [0003] ...

AI Technical Summary

Problems solved by technology

[0003] However, the surface finishing treatment process of the sealing rubber ring in the current market has the following problems in the operation process: a. Due to the installation and fixing construction method of the prefabricated building prefabricated parts, when the prefabricated stairs are hoisted, because the crane operator cannot effectively Observing the position of the prefabricated stairs, the prefabricated stairs cannot be accurately placed on the installation point connecting the floor, and the operator needs to repeatedly adjust the hoist to align, which makes the alignment process of the whole prefabricated stairs more cumbersome; b. Due to the traditional assembly In the prefabricated building installation and fixed construction method, when the prefabricated staircase is hoisted, ropes are used as the connector between the prefabricated staircase and the lifting hook, and when the prefabricated staircase is hoisted by a single rope, the prefabricated staircase connected by the rope will move. It is easy to shake during the process, which not only makes the alignment work of hoisting more difficult, but at the same time, the safety cannot be guaranteed, and the length of the rope is fixed, so it is impossible to effectively hoist prefabricated stairs of different sizes, and the practicability is poor
