Description

Technical Field

[0001] This utility model specifically relates to the field of steel connection technology, and more specifically to a quick connection structure for steel components. Background Technology

[0002] Steel components refer to structural parts made of steel plates, sections, pipes and other steel materials through welding, bolting or riveting, used in engineering fields such as construction, bridges and machinery. When using steel components, in order to improve construction efficiency, ensure construction quality, enhance structural performance and save costs, quick connection methods are generally used for connection.

[0003] Most quick-connect systems currently use specialized high-strength bolts to link steel components together. The principle is to utilize the preload of the bolts to generate friction on the contact surfaces of the connected parts, thereby transmitting force and torque. In bridge construction, high-strength bolts are commonly used to connect steel box girders. During construction, tools such as electric wrenches are used to quickly tighten the bolts, enabling connections to be completed in a short time, with high connection strength and reliability.

[0004] However, in practice, due to the different placement of the two steel structures, the connecting parts required at the connection point are also different. Workers need to select different connecting parts according to the placement of the two steel structures and then fix the connection point. This requires time to find suitable connecting parts, resulting in a lot of time being spent on the connection and affecting the connection efficiency. Utility Model Content
