The standardization and industrialization of components such as steel pipe concrete columns, H steel beams, joints and the like meet the development requirements of green buildings.
The beam-column connection node is used as a force transmission center of a column and a beam, and the construction measure and the calculation method of the beam-column connection node are one of main problems in frame structure design and are also one of key problems directly influencing the mechanical property of the frame structure. Therefore, the node form has the advantages of simple structure, good integrity, definite force transmission, safety, reliability, material saving and convenient construction.
The unreasonable design of beam column nodes can cause the condition of 'strong member weakness', so that the structure is seriously damaged under the action of earthquake load, and the life and property safety of people is threatened.
At present, the traditional connection node mainly takes welding as a main part and takes bolt connection as an auxiliary part. Because the on-site welding quality is not easy to control, the complete detection of the brittle fracture part has difficulty, and the welding time is longer, thereby limiting the advantage of quick construction of the fabricated steel structure. On the other hand, the connecting node in the prior art also has the phenomenon that the transmission path is not clear, which causes unnecessary waste.
