Jacking installation method for large-span single-layer aluminum alloy circular reticulated shell

Abstract

The invention relates to a jacking installation method for a large-span single-layer aluminum alloy circular reticulated shell, and belongs to the technical field of building construction. According to the construction method, a local ladder-step-shaped supporting frame is erected on the lower portion of a latticed shell, the latticed shell is assembled on the upper portion of a frame body, a hydraulic jacking machine is erected, the assembling method of lifting while expanding is adopted till the latticed shell is jacked to the in-place height, and finally shape finding and folding are conducted at the high altitude, stainless steel bolts at joints are finally screwed, positioning and seating are conducted, and graded synchronous unloading is conducted to complete latticed shell installation. According to the method, the purposes of low construction cost, high construction speed, advanced technology, safety, reliability and excellent quality are achieved, the method is applied to installation of the large-span single-layer aluminum alloy latticed shell for the first time in China, and the method is of great significance to improvement of engineering construction safety, guarantee of engineering quality and reduction of engineering cost and has good application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to the construction of a single-layer aluminum alloy reticulated shell, in particular to a method for jacking and installing a large-span single-layer aluminum alloy circular reticulated shell. Background technique [0002] With the rapid development of my country's economy and people's pursuit of high-quality urban buildings, buildings with large-span aluminum alloy single-layer reticulated shell structures have appeared in some cities in my country, becoming the highlight of architectural art quality and improving the quality of cities. At the same time, the aluminum alloy reticulated shell structure adopts factory production, and the on-site assembly construction is in line with the national policy orientation of developing assembly buildings and green construction. The structure of the single-layer aluminum alloy reticulated shell is simple and clear in...

AI Technical Summary

Problems solved by technology

The structure of the single-layer aluminum alloy reticulated shell is simple and clear in shape, beautiful in color and texture, and has certain application prospects. However, the installation of aluminum alloy reticulated shells is mainly based on the full-height bracket method, which has high construction costs, heavy work at heights, and long construction periods. Therefore, the research on its construction technology is of great significance to improve the construction safety, ensure the quality of the project and reduce the cost of the project.
