Novel steel structure connecting piece

Abstract

The invention belongs to the field of steel structures, and particularly relates to a novel steel structure connecting piece. The novel steel structure connecting piece comprises a shell, wherein a feeding hole is formed in the shell; a conical hole is formed in the bottom surface of the feeding hole; a circular hole is formed in the bottom surface of the conical hole; a second air bag is fixedly connected to the interior of the shell, and the second air bag is located on the bottom surface of the conical hole; the second air bag is fixedly connected with a second air guide pipe; a first air bag is fixedly arranged in the circular hole; the first air bag is fixedly connected with a first air guide pipe; the upper end of the first air bag is fixedly connected with a base plate; the upper end of the second air bag is fixedly connected with a limiting block; a sliding groove is formed in the inner side wall of the shell; and a connecting block is arranged in the sliding groove in a sliding mode. The novel steel structure connecting piece is simple in structure, materials to be connected can be locked without damaging the materials to be connected, and meanwhile, the connecting materials can be conveniently unlocked.

Description

technical field [0001] The invention belongs to the field of steel structures, in particular to a novel steel structure connector. Background technique [0002] The members or parts of the steel structure are usually connected by welds, bolts, rivets or clamps, and the connection methods of welding and rivets are generally irreversible connections. The production here caused loss, and at the same time, the bolt connection method was adopted, which required opening holes between the components or parts of the steel structure; after dismantling, it was necessary to remove the opening part and re-open the hole for positioning when it was reused, resulting in loss of steel. At the same time, the clamp can only connect tubular steel, and the diameter of the clamp limits the diameter of the material to be connected, so this connection method has limitations. [0003] There are also some technical solutions for new steel structure connectors in the prior art. For example, a Chines...

Problems solved by technology

[0004] In order to make up for the shortcomings of the existing technology, it is difficult to open holes when connecting steel structure materials. At the same time, the connection is cumbersome and inconvenient to disassemble. When reusing steel structure materials, the opening part needs to be removed, which causes loss of materials. , the present invention proposes a new type of steel structure connector
