Problems solved by technology
[0002] At present, there are many connection technologies between the structural members of various fabricated truss supports. Most of the connection node technologies, including buckle joint connection technology, require the use of connecting bolts to lock the connection. When transferring stress, the connecting bolts need to be directly tensioned, compressed or sheared, which is unsatisfactory in terms of safety, reliability, and durability. The assembly and construction process of structural members has high technical requirements for workers and high labor intensity. The latest connecting head that does not require connecting bolts is a sleeve joint, but because the sleeve joint is a complete cylindrical structure, its assembly and construction are subject to many restrictions, and it must be inserted by the end of the connecting rod to be connected. And because it is a complete cylinder, the connecting rods formed by it cannot implement the extension connection between the same levels, and the application and assembly construction of the socket joint is extremely inconvenient

Embodiment Construction
[0015] A self-fastening bar connector, which includes: a long joint (1) and a short joint (2); the long joint and the short joint are respectively placed at both ends of a long bar body and fixedly connected to form a connecting bar. The long joint (1) described above includes: a long connecting part (3), a long fastening slope (7), and a long fastening part (4); the short joint (2) includes: a short connecting part (5), a short Fasten the bevel (8), the short buckle (6), the short connection reinforcement (10+18); the long buckle (4) on the two connecting rods and the short buckle ( 6) The upper and lower dislocations are closely attached to the connecting rod (14) to be connected, and the buckles are slid toward each other along the axial direction of the connecting rod (14). The long fastening slope (7) and the short fastening slope (8) ) press each other to order the long fastening part (4) and the short fastening part (6) to form a shrinking cavity and connect the connect...

The invention provides a self-fastening rod connecting head. The self-fastening rod connecting head comprises a long connecting head and a short connecting head, the long connecting head is provided with a long fastening oblique face, and the short connecting head is provided with a short fastening oblique face. The long connecting head and the short connecting head accomplish self-fastening connection and fastening connection with communicating rods that need to be connected through the interaction of the long fastening oblique face and the short fastening oblique face, the long connecting head and the short connecting head that accomplish fastening connection do not need connection bolts to transmit stress, the assemble and construction are easier and the work load is smaller; the self-fastening rod connecting head is higher in safety, reliability and durability, and at the same time has high strength of sleeved heads and better and more convenient assemble characteristic than buckle heads, and is a revolutionary and breakthrough node technology.
Description
technical field [0001] The invention relates to the connection technology of joints between the structural members of the truss support body. After the connecting members of the invention are extended and connected at the same level, the connecting members do not need to rely on the connecting bolts to transmit tension or pressure to each other. Direct transmission, effectively improving safety, reliability, and durability, is an important node connection technology for stable support trusses with high load-bearing capacity. It is suitable for industrial production, easy and convenient to assemble, takes up little space after assembly, and has excellent mechanical properties of the structure . Background technique [0002] At present, there are many connection technologies between the structural members of various fabricated truss supports. Most of the connection node technologies, including buckle joint connection technology, require the use of connecting bolts to lock the ...
