Description

Technical Field

[0001] This utility model belongs to the technical field of steel-wood structure rafters, specifically relating to a steel-wood structure rafter connection node. Background Technology

[0002] Steel-wood rafter joints are a structural connection method that effectively combines steel and wood, making them particularly suitable for architectural scenarios that require a balance between strength and aesthetics. A steel-wood rafter joint mainly consists of three parts: steel beams, wooden rafters, and custom-made steel connectors. The steel connectors, as key components, act as a bridge, firmly connecting the steel beams and wooden rafters together.

[0003] When connecting existing steel beams and wooden rafters, the traditional method involves welding or using fasteners such as self-drilling screws, steel nails, or twist nails, which pass through pre-drilled holes in the steel connectors to secure them. This connection method is cumbersome because it lacks any assembly guidance structure, which may lead to instability and positional deviation. Therefore, we propose a steel-wood rafter connection node. Summary of the Invention

[0004] The purpose of this utility model is to provide a steel-wood rafter connection node to solve the problems of inconvenience and instability in connecting steel beams and wooden rafters mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel-wood structure rafter connection node, including a rafter, a steel beam provided at one end of the rafter, a connection and fixing mechanism provided between the steel beam and the rafter, and an assembly guide mechanism provided at the end between the steel beam and the rafter, the connection and fixing mechanism including: a connection clip assembly and a locking assembly.

[0006] Preferably, the connecting clip assembly includes a connecting node sleeved on the end surface of the rafter and the steel beam.

[0007] Preferably, the surfaces of the rafters and the steel beams are symmetrically provided with connecting grooves, and connecting rods are symmetrically fixed to the inner side of the connecting nodes, and the connecting rods are engaged with the connecting grooves.

[0008] Preferably, the end of the connecting rod is provided with a mating groove, and the inner wall of the rafter is symmetrically fixed with mating blocks, which are engaged with the mating groove.

[0009] Preferably, the docking block has symmetrical slots on both sides, and the inner wall of the docking slot is symmetrically fixed with buckles, which engage with the slots.

[0010] Preferably, the locking assembly includes a locking hole on one side of the connecting rod and through holes symmetrically formed through the inner wall of the rafter. Screw holes are symmetrically formed through both ends of the connecting node. A locking rod is provided at the top of the connecting node, passing sequentially through the screw holes and the through holes. The end of the locking rod is screwed into and fixedly connected to the locking hole.

[0011] Preferably, the assembly guide mechanism includes a guide groove formed on one end surface of the steel beam and a guide block fixed on one end surface of the rafter, wherein the guide block is engaged with the guide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through its designed connecting nodes, connecting grooves, connecting rods, mating grooves, mating blocks, slots, and buckles, enables accurate connection and positioning of rafters and steel beams. Simultaneously, the designed locking holes, through holes, screw holes, and locking rods ensure secure locking and positioning after connection. Compared to existing technologies, this greatly simplifies the connection process between rafters and steel beams. Attached Figure Description
