Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure connecting piece. Background Art

[0002] Steel structure is mainly made of steel materials such as steel plates. It is a type of building structure. Due to the high strength of steel structure, it is widely used in the construction field and is often used as a support for some buildings.

[0003] Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength and better earthquake resistance. In addition, since the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Since steel is reusable, it can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely used in countries around the world and is used in industrial and civil buildings. Building steel structures are installed quickly and are quick to construct, and connectors are needed to firmly connect the steel.

[0004] During use, the steel structure connectors in the prior art cannot limit the bolts and nuts used for connection, making the bolts and nuts susceptible to excessive temperature differences caused by rapid changes in the surrounding environment, causing the materials of the bolts and nuts themselves to easily expand or contract. At the same time, after the connector is connected to the steel, the steel is hit by external force, causing the bolts and bolts of the connector body to vibrate, which can easily cause the bolts and nuts to loosen and fall off, thereby affecting the effect of the steel connection. For this reason, a steel structure connector is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a steel structure connector, which aims to improve the problem in the prior art that the bolts and nuts used for connection cannot be limited, resulting in the bolts and nuts becoming loose and falling off when the steel is hit by external force, thereby affecting the connection effect of the steel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A steel structure connector, comprising a steel material, a fixing ring is arranged on the outer periphery of the steel material, a connecting block is fixedly connected to the top of the fixing ring, a fastening bolt is arranged in the middle of the connecting block, a fixing shell is fixedly connected to one side of the connecting block, a shifting block is slidably connected to the middle of the fixing shell, a clamping block is fixedly connected to one side of the shifting block, and a reset assembly is arranged on the side of the shifting block away from the clamping block;

[0008] As a further description of the above technical solution:

[0009] The reset assembly includes a spring, the spring is fixedly connected to one side of the shift block, and two springs are specifically provided, and the two springs are both arranged inside the fixed shell;

[0012] As a further description of the above technical solution:

[0013] The connecting assembly includes a turning handle, and the turning handle is fixedly connected to one end of the threaded rod;

[0014] As a further description of the above technical solution:

[0015] Specifically, two shifting blocks are provided, and both shifting blocks are slidably connected to the middle part of the fixed shell;

[0016] As a further description of the above technical solution:

When the card block is separated from the card slot, the fixation of the fastening bolt can be released. On the contrary, the fastening bolt can be fixed and limited, thereby preventing the fastening bolt from loosening and falling off when the steel is hit by external force, thereby improving the connection effect of the steel.

[0024] 2. In the utility model, the threaded rod is driven to rotate by turning the handle, and when the threaded rod rotates, the fixing block is driven to move, so that after the connecting piece fixes the steel, the connection can be further stabilized.
