Description

Technical Field

[0001] The utility model relates to the technical field of steel tube bundle shear walls and provides a detachable auxiliary tool for installing a steel tube bundle shear wall. Background Art

[0002] When the steel tube bundle shear wall is manufactured by the processing plant, the welded ear plates are installed on site at the component hoisting position. Since the ear plates are only connected to the wall surface by welding and are not connected to the internal structure of the wall, the ear plate structure connection is poor in firmness, which poses a safety hazard during the hoisting process. In addition, it is difficult to play a role in straightening the wall when the steel tube bundles are connected, and misalignment problems are prone to occur, affecting the quality of the wall connection.

[0003] During the processing and after the installation of the steel tube bundle shear wall, the components need to be welded and cut, which will cause irreversible damage to the steel tube bundle components with a wall thickness of only 4mm, affecting the quality of the structure. After the installation is completed, the ear plate is removed by gas welding and cutting. There are also large sparks when the ear plate is cut. The gap between the fire connection device and the welding surface is large, and the welding sparks cannot be effectively connected, affecting fire safety. Utility Model Content
