Steel structure joint used when cable penetrates through steel beam and construction method of steel structure joint

Abstract

The invention relates to the technical field of construction of steel structures and cables, in particular to a steel structure joint used when a cable penetrates through a steel beam. Comprising a joint body (1) with a C-shaped projection, a joint closing piece (2), a variable cross-section piece (3) and a steel beam joint piece (4). Wherein the joint body (1), the joint closing piece (2), the variable cross-section pieces (3) and the steel beam joint pieces (4) are all of box beam structures, the joint closing piece (2) is arranged at an opening of the joint body (1) and enables the joint body (1) to be closed, the variable cross-section pieces (3) are arranged at the two ends of the joint body (1), and the steel beam joint pieces (4) are connected with the variable cross-section pieces (3) at the two ends respectively. According to the node construction method, the collision conflict between the cable and the beam can be effectively solved, the construction difficulty is reduced, and it is guaranteed that the beam and the cable do not affect each other during construction and actual use. In addition, the singleness and limitation of the structure type can be effectively solved, and a cable structure system can be perfectly fused into a steel structure system.

Description

technical field [0001] The invention relates to the technical field of steel structure and cable construction, in particular to a steel structure node when cables pass through steel beams and a construction method thereof. Background technique [0002] Due to the rapid development of steel structures, the structural forms are becoming more and more complex, and the unit types in the same structure are complex and diverse. Due to their different characteristics and construction methods, it is difficult to avoid collisions or influences in the structure itself or in actual construction. The cable unit is pre-tensioned in actual use, so the cable is generally straight in most cases, so there cannot be other structures or rods at the position where the cable passes. [0003] At present, generally in the curtain wall structure, the cable structure will collide with the main structure. In most cases, the cables are arranged vertically. At the intersecting position with the beam, o...

Problems solved by technology

[0003] At present, generally in the curtain wall structure, the cable structure will collide with the main structure. In most cases, the cables are arranged vertically. At the intersecting position with the beam, only opening holes in the beam flange can avoid collision. When the arrangement is in other states, The opening may affect the bearing capacity of the steel beam, but in some places it cannot be avoided that the cables collide with other components or affect each other, and because of local influences, the joint section of the steel beam may be made particularly large, which in turn affects the overall steel structure Aesthetics and even design layout
