Aluminum alloy large-model hoisting construction process

Abstract

The invention relates to an aluminum alloy large-model hoisting construction process which comprises the following steps: determining positions of transverse and vertical axes, mounting a rear steel plate according to the positions of the transverse and vertical axes, determining and mounting transverse and vertical steel keels at left and right positions and in and out positions of keels, reliably connecting the keels and the rear steel plate and performing full-length welding, cutting aluminum alloy square tubes to enable the aluminum alloy square tubes to have 45-degree splicing angles, and then an aluminum alloy large-model finished product is assembled, the aluminum alloy large-model finished product is hoisted to the installation position and fixedly installed with the keel, and a mold opening decorative cover is adopted to hide a fixing point. By means of the construction technology, the installed aluminum alloy large model has the advantages of being large in span, long in overhanging distance, high in precision and clean and tidy in overall visual sense of the outer curtain wall.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a large-scale aluminum alloy hoisting construction technology. Background technique [0002] With the continuous improvement of people's living standards in our country, the requirements for living conditions have also increased accordingly. At this stage, urban residences are mainly improved, and the appearance of external curtain walls is improved. The development models of various real estate companies are also based on bungalows and villas. Most of them have cantilevered structures such as balconies, air-conditioning panels, and bay window panels in all types of residences, and there is a certain deviation between the cantilevered structures and the overall exterior wall and facade profile of the building.

[0002] With the continuous improvement of people's living standards in our country, the requirements for living conditions have also increased accordingly. At this stage, urban residences are mainly improved, and the appearance of external curtain walls is improved. The development models of various real estate companies are also based on bungalows and villas. Most of them have cantilevered structures such as balconies, air-conditioning panels, and bay window panels in all types of residences, and there is a certain deviation between the cantilevered structures and the overall exterior wall and facade profile of the building. In order to improve the overall appearance of the building's facade, Generally, the decorative wall foundation is built on the back town soil around the main building, and then the wall is built to connect to the bottom of the cantilever structure to achieve the effect of consistent exterior facade contours. However, the construction accuracy of this ordinary exterior curtain wall is not high and insufficient. It is firm, and after a long time, cracks will appear at the connection between the part of the decorative wall and the overhanging structure. It is not suitable for construction and installation with large spans and long overhangs, and the overall exterior curtain wall after installation is not beautiful enough.
