Description

Technical Field

[0001] This utility model relates to the field of modular steel structure technology, and in particular to a connection node for a modular steel structure component and its modular steel structure. Background Technology

[0002] Modular steel structures are a common building structure that uses modular design to splice together multiple steel structures to create steel structures of different sizes according to actual needs. In practical use, modular steel structures generally only use bolts to fix one side of two modular steel structures, lacking a redundancy mechanism. If a bolt at the connection fails, the safety of the entire connection will be greatly reduced, affecting the stability of the entire structure. A Chinese patent discloses a "connection node of modular steel structural components and its modular steel structure", with application number "CN202221702108.1". It realizes the function of further calibration and initial fixation of the splicing plate position, and realizes the connection function of the splicing plate with fixing holes and through holes. However, it cannot solve the problem of only using bolts to fix one side of two modular steel structures, lacking a redundancy mechanism, and the problem that if a bolt at the connection fails, the safety of the entire connection will be greatly reduced, affecting the stability of the entire structure.

Two modular steel structure bodies are then fixed by a hinged fixing plate on a connecting frame one, providing double fixation for the two modular steel structure bodies. Even if one fixing method fails, the other fixing method can still provide support and stability. By rotating the nut on the outer surface of the threaded rod one, the connecting block can be rotated or fixed. At the same time, the connecting block can rotate 90 degrees, allowing the connecting frame one to be connected horizontally or vertically to other connecting frames one through the outer connecting frame two, adapting to different usage requirements.
