Description

Technical Field

[0001] The utility model relates to the technical field of steel structure fixing structures, in particular to a clamping and fixing structure for steel structure installation. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel and steel plates. In construction, the steel structure needs to be hoisted. During the hoisting, the construction workers need to use corresponding equipment and fixed structures for steel structure installation to assist the operation;

[0003] When installing steel structures, construction workers use lifting equipment to lift the steel structures for installation. The lifting equipment needs to fix the steel structures first when lifting them, and then lift the steel structures to the designed height for installation. Lifting equipment generally fixes the steel structures with steel wire ropes or hooks, but it is difficult to effectively fix the steel structures with steel wire ropes and hooks, and the process of fixing the steel structures is relatively cumbersome, which is not only inconvenient for construction workers to use, but also has certain safety hazards in the process of lifting the steel structures. Utility Model Content

[0004] In order to solve the problem that it is difficult to effectively fix the steel structure, the utility model aims to provide a clamping and fixing structure for installing the steel structure.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: it includes a lifting plate, a gear is rotatably provided inside the lifting plate, a rotating rod is fixedly inserted in the gear, both ends of the rotating rod are rotatably installed with the inner wall of the lifting plate, both sides of the gear are meshed with tooth plates, the tooth plates are diagonally distributed, one end of the tooth plate slides through the two side walls of the lifting plate respectively, the ends of the tooth plates away from each other are fixed with connecting blocks, the sides of the connecting blocks away from each other are fixed with connecting plates, and the bottom ends of the connecting plates are fixed with clamping plates.

[0006] Preferably, a placement plate is fixedly provided at the bottom end of each of the clamping plates, one end of the placement plate is inclined, and the placement plates are distributed in a mirror image.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. This application can effectively fix the steel structure, making it convenient for construction workers to clamp and fix the steel structure, and avoiding safety hazards during the lifting of the steel structure.

[0009] 2. The present application can achieve the effect of supporting the steel structure. During the lifting process of the steel structure, by placing the steel structure on the placement plate, the clamping plate can fix the steel structure more firmly.

[0010] 3. The present application can achieve the goal of retracting the tooth plate into the lifting plate when the present structure is not in use, which can effectively reduce the floor space occupied by the present structure. BRIEF DESCRIPTION OF THE DRAWINGS
