Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, and in particular to a modular steel structure wedge-nail-mortise and tenon type connection node structure. Background Art

[0002] Prefabricated steel structure building is a new type of construction technology, which is characterized by the use of prefabricated steel structure modules, which are assembled on site. The main connection method between traditional steel structure modules is bolt connection. Bolt connection requires a large operating space on site, and the number of bolts required is large, which is labor-intensive, low in safety, and poor in flexibility. The reasons are as follows: 1) The forces between the components of the bolt connection node are complex. Therefore, when designing the connection node, for safety reasons, more bolts need to be set. Too many bolts consume more bolts, increase steel costs, extend construction time, and increase labor costs. 2) Too many bolts are set at the connection, indicating that there are too many openings. Too many openings lead to stress concentration and uneven force at the node, and low safety; 3) Bolt connection nodes are difficult to install and disassemble, and have poor flexibility. Therefore, there is an urgent need for a connection structure that can connect steel structure modules tightly and is easy to disassemble. Summary of the invention

[0003] In view of this, the present invention provides a modular steel structure wedge-nail-tenon type connection node structure to solve the problem of lack of a connection structure that can connect steel structure modules tightly and easily be disassembled.
