Description

Technical Field

[0002] Steel structure connectors for construction are metal parts used to connect steel components. Currently, existing steel structure connectors on the market are mainly improved in terms of functionality and other aspects.

Under the friction between the T-shaped compression bolts 11 and the corresponding hard rubber, the disc 9 is fixed, thereby fixing the connecting steel rod 1. The adjustment is completed. The adjustable connection angle can be applied to steel components with different angle deviations, thereby improving the scope of application. In addition, the adjustable length and angle of the connecting piece do not require personnel to perform separate welding operations during connection, thereby reducing labor intensity, facilitating personnel operation, and improving operating efficiency.
