Description

Technical Field

[0001] The present application relates to a method for using a lifting hook that does not damage the H-shaped cross structure, and belongs to the field of building structural components. Background Art

[0002] In steel structure projects, there is a node of the H-shaped steel cross structure. The node of the H-shaped steel cross structure is a cross structure formed by the intersection of two H-shaped steels. During the fabrication of components, due to different processes, it is necessary to transfer the components. During the transfer process, a lifting tong is usually used. After using the lifting tong, there will be scratches on the component, causing damage to the structural member, and subsequent repair and grinding treatments are required.

[0003] Therefore, to solve the above technical problems, it is indeed necessary to provide a lifting hook that does not damage the H-shaped cross structure to overcome the defects in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for using a lifting hook that does not damage the H-shaped cross structure, ensuring that during the process of lifting components, the H-shaped cross structure will not be damaged and the safety of lifting can be ensured.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a method for using a lifting hook that does not damage the H-shaped cross structure. The lifting hook includes a hook body. The hook body includes two hook walls. One end of the hook wall is provided with a hook end. The other ends of the two hook walls are connected to form a bending part. Between the hook wall and the hook end is a hook cavity. The shape of the hook cavity matches the cross angle of the flange of the H-shaped steel cross structure. The method for using the lifting hook includes the following steps: 1), Place the two hook bodies at two opposite cross angles of the flange of the H-shaped steel cross structure. The hook ends of the hook bodies are located inside the H-shaped steel cross structure, and the bending parts of the hook bodies are located outside the H-shaped steel cross structure; 2), Pass a sling through the bending parts of the two hook bodies; 3), Lift the sling upward so that the hook ends of the two hook bodies push against the H-shaped steel cross structure in the moving direction of the lifting rope to form a self-locking, and complete the lifting of the H-shaped steel cross structure.

[0006] By adopting the above technical solution, the hook body is composed of two hook ends, increasing the contact area with the H-shaped steel cross structure. The two hooks are installed on both sides of the H-shaped steel cross structure, and a sling passes through the bending parts of the two hook bodies. The usage method is simple.

[0007] The method for using a lifting hook that does not damage the H-shaped cross structure of the present invention is further provided as: the hook body is formed by bending a shaped plate 180 degrees from the middle position, and the bending place is the bending part.

[0008] By adopting the above technical solution, the structure of the hook body is simpler and more convenient to manufacture compared with the existing perforated structure.

[0009] The usage method of a lifting hook for an H-shaped cross structure without damage according to the present invention is further set as: the two hook walls of the hook body are parallel to each other.

[0010] By adopting the above technical solution, the parallelism ensures that the lifting rope can easily enter the bending part.

[0011] The usage method of a lifting hook for an H-shaped cross structure without damage according to the present invention is further set as: the distance between the two hook walls is greater than 3 cm.

[0012] By adopting the above technical solution, 3 cm is greater than the diameter of the lifting rope.

[0013] The usage method of a lifting hook for an H-shaped cross structure without damage according to the present invention is further set as: the side of the hook end close to the H-shaped steel cross structure is a straight and flat structure.

[0014] By adopting the above technical solution, the contact area with the H-shaped steel cross structure is increased to reduce the loss of the H-shaped steel cross structure during transportation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The lifting hook for an H-shaped cross structure without damage in the present invention has a simple and convenient structure for manufacturing and a stable structure;

[0016] 2. The usage method of the lifting hook for an H-shaped cross structure without damage in the present invention has a simple usage method and effectively solves the problem of damage to the H-shaped cross structure. BRIEF DESCRIPTION OF THE DRAWINGS
