Precast high-strength building beam and column node component

Abstract

A precast high-strength building beam and column node component is used for connection of steel structure building beam and column nodes, and overcomes the defects that labor is wasted, accuracy is poor, and intensity is low in existing connecting methods. The precast high-strength building beam and column node component is composed of lap joints which are precast on the end of a beam and the end of a column, a collection joint collecting all the lap joints on a node and an anti-separation component. Each lap joint comprises a tenon seat, a lap tenon and an inserting tenon, each lap tenon is welded on one side, facing the node, of the corresponding tenon seat, each inserting tenon is welded on one side, facing the beam or the column, of the corresponding tenon seat, and each lap tenon is formed by an inner side plate, an outer side plate, an archy supporting plate and a butt joint end socket. The collection joint is composed of a regular hexahedron multidirectional node tenon seat and all bearing tenons in needed directions of the node tenon seat, the end face of the node tenon seat and the end face of the tenon seat in each lap joint are identical in structure, and the bearing tenons and the lap tenons are identical in structure. The precast high-strength building beam and column node component has the advantages that eventually formed lap joints and the collection joint are standard in shape and size, the beam and the column are high in assembly accuracy and large in intensity at the node position, and the high-efficiency construction mode that the connecting components of the node position of the beam and the column are precast in factories and assembled in construction sites simply and conveniently is achieved.

Description

technical field [0001] The invention belongs to building components, and in particular relates to a connection method for beams and columns of a steel structure or frame structure building at intersection nodes. Background technique [0002] In the past, the joints of beams and columns in steel structures were mostly welded, rivets or bolts on site. The connection is directly welded on site. Direct welding connection, there are difficulties in component suspension and support stability, poor installation accuracy and uncertainty, fast cooling and large deformation during welding, large stress is easily formed at the weld, uneven metallographic structure at the weld, and material Embrittlement and many other factors reduce strength, reduce safety, low seismic performance, and high construction cost. Although the metallographic structure of the connection points of the components has not changed in the riveting and bolt connections, the workload of component preprocessing is...
