Problems solved by technology

The above-mentioned technical solution can be applied to heavier bolted joints, but it needs to be transported by the tower crane or the auxiliary traction of the chain to be in place, because it will take more time for the tower crane or the chain to be used, which will affect the overall installation period.
In addition, the above-mentioned installation method requires a large amount of auxiliary measures for installation. After the steel structure is installed, the auxiliary measures need to be disassembled, which will consume part of the man-hour and increase the cost of labor and machinery.

Abstract

The invention discloses an installation switching device for a large-scale bolt gusset plate of a steel structure. The device includes a steel beam and a gusset plate body, and the gusset plate body is rotatably in pivot connection with the steel beam through a switching device body; the switching device body includes multiple fixing sleeve bases and overturning shafts matched with the fixing sleeve bases, the lateral surfaces of the fixing sleeve bases are fixedly connected to the surfaces of steel beam webs, one section of each L-shaped overturning shaft is inserted into a central hole of the corresponding fixing sleeve base, and the end portion of the other section of each overturning shaft is fixedly connected with the gusset plate body. According to the technical scheme, compared withthe prior art, the installation switching device for the large-scale bolt gusset plate of the steel structure can increase the safety coefficient of installation of the large-scale bolt gusset plate,improve the construction efficiency and save the manpower and cost.

Description

technical field [0001] The invention relates to the technical field of steel structure installation, in particular to an opening and closing device and an installation method for installing a large bolt gusset plate of a steel structure. Background technique [0002] With the continuous development of my country's economy, the construction height of buildings is constantly being refreshed, and in high-rise buildings, steel structures are usually used as the body of high-rise buildings. In addition, the current steel structure engineering is gradually developing towards high, large, new, sharp, special and heavy steel structures, among which large high-strength bolt joints are more and more widely used. [0003] Since large high-strength bolted gusset plates are often large in steel plate thickness and length and width, and the gusset plate is overweight, there is a greater risk of falling from high altitudes when using traditional manual handling and installation of gusset p...
