Embodiment Construction
[0015] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
[0016] figure 1 It shows the steel structure hoisting lug cutting method provided by the present invention, including the following content: A. Cut off the backing plate 1 through the hoisting lug 3 of the steel structure 2 and stick it on the surface of the steel structure 2, so that the hoisting lug 3 is exposed Cut off the backing plate 1; B. Cut off the hoisting ear plate 3 outside the backing plate 1.
[0017] The butt steel structures 2 connect and align their hoisting lugs 3 through splints 4 , and weld the joints of the two steel structures 2 to complete the connection and installation of the steel structures. Cut off the backing plate 1 and attach it to the surface of the steel structure 2. When cutting off the hoisting lug 3, cut off the lifting lug 3 along the surface of the cut off backing plate 1, whi...

Abstract
The invention discloses a method for cutting off a hoisting ear plate of a steel structure and a cutting backing plate used therefor, and belongs to the technical field of steel structure installation and construction, and includes the following contents: A. passing the cutting backing plate through the hoisting ear plate of the steel structure and sticking it on On the surface of the steel structure, the hoisting ear plate is exposed to the cutting backing plate; B. Cut off the hoisting ear plate outside the cutting backing plate. Use the cutting backing plate to isolate the steel structure from the high temperature generated by cutting, protect the steel structure, prevent the deformation of the steel column due to high temperature during the cutting process, and ensure the quality. Moreover, the surface of the steel structure after cutting does not need to be repaired, which improves the quality of the steel structure. efficiency.
Description
technical field [0001] The invention relates to the technical field of steel structure installation and construction, in particular to a method for cutting off a steel structure hoisting lug plate and a cutting backing plate used therefor. Background technique [0002] In the installation process of the steel structure, in order to facilitate the hoisting and connection correction of the steel structure, the hoisting lug plate is usually welded at the end of the steel structure, and the hoisting lug plate bolts of the adjacent steel structures are connected through the splint to make the steel structure straightened and aligned. Then weld the butt joints of the two steel structures to realize the connection and installation of the steel structures. After the on-site steel structure butt welding is completed and the flaw detection is qualified, the hoisting lugs need to be cut off. Nowadays, the hoisting lugs are usually cut off directly from the steel structure, but the high...
