Steel structure beam-column joint

Abstract

The invention discloses a steel structure beam-column joint, which comprises a bearing column, a steel beam, a buffer steel block, a protective steel sleeve, a reinforcing bolt, a reinforcing nut, anda bearing supporting plate. The protective steel sleeve sleeves outside the bearing column; the bearing supporting plate is arranged vertically and horizontally on the outer side of the bearing column and is arranged on the lower edge of the protective steel sleeve; the buffer steel block is arranged between the steel beam and the protective steel sleeve, and is placed above the bearing supporting plate; the buffer steel block is internally provided with a groove; and the upper end of the reinforcing bolt is movably arranged in the groove, the lower end of the reinforcing bolt penetrates through the buffer steel block and the bearing supporting plate successively, and the buffer steel block and the bearing supporting plate are fixedly connected by using the reinforcing nut. According to the steel structure beam-column joint, extension treatment of the connection point between the bearing supporting column and the steel beam is realized, at the same time, it is greatly convenient to disassemble and recycle the bearing column and the steel beam, the reinforcing bolt is mounted movably on the inner side of the buffer steel block, thus prefixing of the steel beam and the bearing supporting plate is realized, hole finding time is shortened, and the assembly efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of steel structures, in particular to a beam-column node of a steel structure. Background technique [0002] The existing beam-column joints of steel structures are mostly fixed by welding when they are fixed to the steel beams. Although the stability is extremely strong, it is extremely inconvenient to disassemble and recycle, resulting in great economic waste. At the same time, the steel beams fixed by bolts Beams can easily lead to the fracture of the connection point between the steel beam and the load-bearing column, which has caused great trouble to the user, and when the general steel beam is installed, the stagnation phenomenon of the clamping point often occurs, which leads to deformation of the clamping point, reducing the The problem of node service life. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the purpose of the present invention is to pro...
