Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel structure fastening component for rapid building construction. Background Technology

[0002] Steel structure fastening components for rapid construction are connection devices specifically designed for the efficient assembly needs of steel structure buildings. They typically consist of a main body that adapts to the interfaces of steel components and matching locking components. Their core function is to achieve rapid alignment and reliable fixation of steel structure components. Through standardized structural design, they simplify the traditionally complex connection process, significantly reducing component installation time while ensuring the load-bearing strength of the nodes. They are mainly used in steel structure engineering scenarios requiring rapid assembly, such as factories, modular buildings, and temporary bridges, significantly improving construction efficiency and reducing labor and time costs.

[0003] A search revealed that CN222685699U discloses a steel structure node connector for building construction, belonging to the field of building construction technology. It includes an installation plate, two positioning plates are mounted on one side of the installation plate, a connecting plate is mounted between the two positioning plates, an installation frame is mounted on one side of the connecting plate, an installation groove is opened on the surface of the installation frame, and two rectangular grooves are opened inside the installation frame, with the two rectangular grooves located on the upper and lower sides. Two sets of fastening components are also mounted on the installation frame.

[0004] The steel structure node connector in the prior art document, although it is installed by inserting it into the steel beam through the installation slot, strengthening the bolt fixation, and cooperating with the moving plate to press against the steel beam to complete the installation, thereby improving the node strength and reducing loosening, the installation process is cumbersome and not convenient for quickly connecting two steel structures, which limits the efficiency of the device.

[0005] Therefore, we propose a steel structure fastening component for rapid building construction. Utility Model Content
