H type steel beam and H type steel column major axis assembled joint and construction method

Abstract

The invention relates to an H type steel beam and H type steel column major axis assembled joint and a construction method. The joint comprises an H type steel beam and an H type steel column. The H type steel beam comprises an upper wing plate, a lower wing plate and a web plate. The joint also comprises a first connecting part, a second connecting part and a third connecting part; the first connecting part comprises a first plate, a second plate and a first insertion block; the first plate is connected to the H type steel column by a bolt; the second plate is fixed to the web plate by a bolt; the first insertion block is arranged on the first plate, and the wing plate of the H type steel column is provided with a first insertion slot; the second connecting part comprises a first verticalplate, a first transverse plate and a second insertion block, and the first vertical plate is connected to the H type steel column by a bolt; the first transverse plate is connected to the lower wingplate by a bolt; the second insertion block is arranged on the first vertical plate, and the wing plate of the H type steel column is provided with a second insertion slot; and the third connecting part is fixedly arranged on the upper wing plate, and the third connecting part is connected to the H type steel column by a bolt. The joint is constructed and mounted on site conveniently, the shearing force of the bolt can be reduced, and a condition that the connecting stability of a beam column is affected as the bolt is damaged is reduced.

Description

technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to an H-shaped steel beam and H-shaped steel column strong shaft assembled node and a construction method. Background technique [0002] As a representative of green buildings, steel structure has the characteristics of good material comprehensive performance, high material utilization rate and superior safety performance. In multi-story and high-rise steel structures, H-shaped steel beams and H-shaped steel columns are used as the main load-bearing components, and the nodes used to connect H-shaped steel beams and H-shaped steel columns are mainly used to transmit bending moments and The effect of shear force is the key to affect the mechanical properties of steel structure houses. [0003] At present, the most commonly used beam-to-column joints in prefabricated steel structure houses are bolted welded joints. The bolt-welded connection node is to w...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: in the process of using bolts to connect the steel column and the connecting plate, it is necessary to maintain the abutment of the opposite end faces of the steel column and the connecting plate and the alignment of the corresponding bolt installation holes and place the bolts at the same time , it is very inconvenient for the staff to construct and install on site; at the same time, there is serious stress concentration at the bolt connection between the end plate and the steel column, and the force perpendicular to the length direction of the steel beam is subjected to the corresponding shear force by the bolt , when the steel beam is under a large force, the bolts may be damaged and affect the stability of the beam and column connection
