Hoisting method for three-layer combined steel column sandwich heat preservation external wall panel of fabricated steel structure house

Abstract

The invention discloses a hoisting method for a three-layer composite steel column sandwich heat preservation external wall panel of a fabricated steel structure house, belongs to the field of hoisting. The hoisting method for the three-layer composite steel column sandwich heat preservation external wall panel of the fabricated steel structure house is characterized in that inner adjusting bags are arranged in the multi-layer external wall panels, before the multi-layer outer wall plate is vertically fixed on the wall body, the sunken part can be inflated and bulged until the sunken part is flush with the surface of the adjacent fixed heat preservation external wall panel, and then cement slurry is filled, so that compared with the prior art, the position of the multi-layer external wallpanel can be adjusted, the mounting perpendicularity of the multi-layer external wall panel is further remarkably improved, the mounting effect is better after hoisting, meanwhile, through cooperationwith the effect of pre-degradation rubber balls, after long-time use, the connecting strength between the multi-layer external wall panel and the wall body can be effectively enhanced, the situationthat after long-time use, the connecting strength is reduced, and loosening occurs is effectively avoided, and the potential safety hazard that the wall panel falls off is remarkably reduced.

Description

technical field [0001] The invention relates to the field of hoisting, more specifically, to a hoisting method of a three-layer composite steel column sandwich thermal insulation outer wall panel of a prefabricated steel structure house. Background technique [0002] For the installation of traditional prefabricated exterior wall panels, the exterior wall panels are erected on the exterior wall panel storage racks during installation, and can be lifted and installed directly. This method is only applicable to the case where the height of the prefabricated exterior wall panels is not large. This patent relates to the installation and fixation technology of multi-layer prefabricated exterior wall panels of prefabricated steel structure houses. Prevent the outer pages of multi-layer exterior wall panels from cracking and fix them with multi-layer exterior wall panels. [0003] In the installation and construction of prefabricated residential exterior wall panels, the tradition...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a method for hoisting the three-layer composite steel column sandwich thermal insulation exterior wall panels of prefabricated steel structure houses. Before the first-layer outer wallboard is vertically fixed on the wall, it can be processed by inflating the inner part until the inner part is flush with the surface of the adjacent fixed thermal insulation outer wallboard, and then filled with cement Compared with the existing technology, the slurry can realize the adjustment of the position of the multi-layer exterior wall panels, thereby significantly improving the installation verticality of the multi-layer exterior wall panels, so that the installation effect after hoisting is better, and at the same time, it is combined with pre-degraded rubber balls After a long time of use, it can effectively enhance the connection strength between the multi-layer exterior wall panels and the wall, effectively avoid the loosening of the connection strength after a long period of time, and significantly reduce the safety hazard of the wall panels falling off
