Description

Technical Field

[0001] The utility model relates to the technical field of steel structure fittings, in particular to a cantilever steel structure connection node. Background Technique

[0002] A cantilever beam is a beam with one end connected to a support and the other end extending out of the support, which is extremely important in buildings. To meet the styling requirements of buildings, many existing buildings will design cantilever shapes with large spans, and the structural dimensions are relatively large. Therefore, steel structure beams are used for cantilevers. In related technologies, in the steel structure cantilever beam structure, the connection between the steel structure cantilever beam, the floor slab and the concrete beam is of utmost importance. Generally, the connection between the floor slab and the steel structure cantilever beam is achieved by bolts, and the connection between the floor slab and the concrete beam is carried out by the chemical anchoring method, so that the steel structure cantilever beam is stably connected to the floor slab and the concrete beam. When building the roof of a house, first drill holes in the floor slab and the steel structure cantilever beam, then inject high-strength anchoring glue, and then insert steel bars or profiles. After the glue cures, the steel bars are bonded to the floor slab and the concrete beam as a whole, and then one end of the steel structure cantilever beam is connected to the floor slab by ordinary bolts. However, the floor slab and the concrete beam are connected separately, and the steel structure cantilever beam and the floor slab are connected separately, so the connection stability of the steel structure cantilever beam is relatively low, which is prone to the defect of engineering accidents.

[0003] A steel structure cantilever beam connector with the publication number of CN205206049U includes a connection main board, with stiffeners arranged on the connection main board, and a connection side board is arranged on each side of the connection main board. The connection side board is perpendicularly arranged to the connection main board, and bolt holes are arranged on the connection side board. The utility model improves the connection strength between the cantilever beam and the concrete column by connecting the connection side board to the concrete column and using the connection main board to connect the cantilever beam. The structure of the utility model is reasonable and meets the requirements of diversified architectural appearance design.

[0004] The above technical solution has some problems in practical applications. This technical solution can only realize the installation of cantilever beams at fixed angles. However, in the actual construction process, the angles of cantilever beams are diverse, and it is difficult to apply this technical solution to the installation of cantilever beams at various angles.

[0005] Therefore, it is very necessary to invent a cantilever steel structure connection node to solve the above problems. Content of the Utility Model
