Steel structure building beam or pillar node interface

Abstract

The invention relates to a steel structure building beam or a steel structure pillar node interface, which is used for connecting convergent nodes of a steel structure building beam or a steel structure pillar and overcoming the shortages of toilsome assembly, bad accuracy, low connection strength, and the like in the existing connection mode. The steel structure building beam or pillar node interface is composed of joints of the end part of the beam or the pillar and joint seats converged on the node, wherein the joints lack a half at the end part in the horizontal direction to form a ladder shape. The shape and the size of the joint seats are the same with that of the joints. A connection insertion tenon is arranged on a mutual faying surface formed when the joint is butt jointed with the joint seat, the connection insertion tenon is vertical to the faying surface and a fastening structure for preventing the joint and the joint seat from horizontally separating is arranged at the faying position of the joint and the joint seat. According to invention, the steel structure building beam or pillar node interface has the beneficial effects that the faying mode bearing of the interface has large bearing capacity; the steel structure building beam-pillar node interface has high longitudinal tensile strength, is provided with the fastening member for preventing the joint and the joint seat from horizontally separating so that the connection of the node of the beam and the pillar has multi-directional higher anti-breaking strength, has a simple structure, and is convenient to manufacture and install; and with the adoption of the steel structure building beam or pillar node interface, the conditions are created for modularization, standardization and serialization of steel structure housing construction.

Description

technical field [0001] The invention belongs to building components, and in particular relates to the connection of steel structure building beams and columns at nodes. Background technique [0002] In the past, the joints of beams and columns in steel structures were mostly welded, rivets or bolts on site. On-site welding is used. During welding, the suspension of components and the stability of support are required to be high. During welding, the cooling is fast and the deformation is large. Large stress is easily formed at the weld, the metallographic structure of the weld is uneven, and the material is brittle, etc. Many factors reduce the strength, the safety is reduced, the seismic performance is low, and the construction cost is high. Although the metallographic structure of the connection points of components has not changed during riveting and bolt connection, due to the large amount of rivets (screws) at the joints, the workload of component preprocessing is large...
