Connecting joint structure for steel structure beam column

Abstract

The invention discloses a connecting joint structure for a steel structure beam column. The structure comprises a steel structure column which comprises a plurality of layers of column bodies, wherein every two adjacent layers of column bodies are connected through a connection device; a steel structure beam which comprises a box girder; flange partition plates which are arranged at the end, connected with the steel structure column, of the box girder, wherein the flange partition plates comprise a plurality of partition plates which are continuously arranged in the circumferential direction of the section of the end of the box girder, and any partition plate extends outwards along the edge of the box girder; and a joint connecting mechanism which is arranged outside the connecting device in a sleeving mode in the circumferential direction of the steel structure column, wherein the joint connecting mechanism is connected with the steel structure column and the steel structure beam, and forms a closed space jointly formed with the joint connecting mechanism, the flange partition plates and the outer side wall of the steel structure column. The joint connecting mechanism is arranged between the steel structure beam and the steel structure column, so that the box girder can be directly connected with the joint connecting mechanism through the flange partition plates conveniently; the single-point stress of the steel structure beam is converted into the circumferential stress of the steel structure column while the connecting strength of the steel structure beam and the steel structure column is improved, so that the stress structure is optimized, and the stress stability is improved.

Description

technical field [0001] The invention relates to the technical field of steel structure foundation construction. More specifically, the present invention relates to the construction of steel structural beam-to-column joints. Background technique [0002] With the development of science and technology, building steel structures are becoming more and more complex. How to safely and reasonably realize complex structures and joints has become the difficulty and focus of in-depth design. When the box girder is connected to the column, rigid connection is usually used, and the diaphragm corresponding to the beam flange runs through the box column. Since the cross section of the steel beam connected to the column is not exactly the same, some diaphragms are very close to each other, and the steel column is covered by the transverse diaphragm. The diaphragm is divided into a small section, and there are many welds in the joint area of ​​the steel column, and the stress concentration...

AI Technical Summary

Problems solved by technology

When the box girder is connected to the column, rigid connection is usually used, and the diaphragm corresponding to the beam flange runs through the box column. Since the cross section of the steel beam connected to the column is not exactly the same, some diaphragms are very close to each other, and the steel column is covered by the transverse diaphragm. The partition is divided into a small section, and there are many welds in the joint area of ​​the steel column, and the stress concentration is obvious, resulting in poor stress stability of the steel column, and the overall stability of the beam-column connection cannot be guaranteed
