X-shaped rib steel beam-column joint reinforcing device

Abstract

The invention relates to an X-shaped rib steel beam-column joint reinforcing device, which comprises a steel beam member, an H-shaped steel column member, horizontal rib plates and an X-shaped rib plate, wherein the left and right flange side walls of the H-shaped steel column member are welded with a steel beam member. Two horizontal rib plates are disposed on the two sides of a web of the H-shaped steel column member respectively at the same height as the upper and lower flanges of the steel beam member. The three sides of the horizontal rib plates are welded on the left and right flanges and web of the H-shaped steel column member. The outwardly extending ends of the X-shaped rib plate are fixedly mounted on the inner side walls parallel to the two horizontal rib plates by high-strengthbolts. The X-shaped rib steel beam-column joint reinforcing device is fixed by high-strength bolts through X-shaped rib plate and joints, which is not only simple and easy to operate, but also suitable for different beam-column sections. The X-shaped rib steel beam-column joint reinforcing device is also used as a replaceable component in the case of small earthquakes and medium earthquakes, which is beneficial to the repair work after the earthquake. The X-shaped rib steel beam-column joint reinforcing device as certain economic benefit.

Description

Technical field [0001] The invention relates to the technical field of steel structure node reinforcement, in particular to an X-shaped rib steel beam-column node reinforcement device. Background technique [0002] Compared with the traditional brick-concrete structure, the steel structure has the characteristics of light weight, high strength and superior seismic performance. It can be reused during the construction process and conforms to the national sustainable development policy. Therefore, it is widely used in domestic steel structure buildings. [0003] The traditional steel frame beam-column joints are complicated in force, which directly determines the reliability of the structure's bearing capacity. At present, most of the existing steel structure buildings still adopt the form of butt welding of beam and column sidewalls, and there will be cracks, pores and other defects in the weld during the welding process, which causes the joint area of ​​the steel structure building...

[0003] The traditional steel frame beam-column joints are under complex stress, which directly determines the reliability of the structure's bearing capacity

At present, most of the existing steel structure buildings still adopt the form of welded beams and column side walls, and there will be defects such as cracks and pores in the welds during the welding process, which leads to the first occurrence of joints in the steel structure building during the load-bearing process. Brittle failure, which violates the design idea of ​​"strong joints, weak components", so it is necessary to strengthen and improve the welded joints of beams and columns
