Steel beam bolting joint structure of horizontal cross-core plate type concrete-filled steel tubular column

Abstract

The invention belongs to the technical field of steel-concrete structures in constructional engineering, particularly relates to a steel beam bolting joint structure of a horizontal cross-core plate type concrete-filled steel tubular column. Aiming at the problems that a beam-column joint is a key part of a fabricated building structure, the performance of the beam-column joint directly influencesthe bearing capacity, anti-seismic property and the like of the structure, and meanwhile the construction and fabricating progress is directly influenced by the structural form of the beam-column joint, the following scheme is proposed, the steel beam bolting joint structure comprises an outer steel pipe and inner pipe concrete which form a steel pipe concrete column, a horizontal elongated slotis formed in the long edge of the outer peripheral surface of the outer steel pipe corresponding to a steel wing, horizontal core penetrating plates are arranged in the short edge direction of the outer steel pipe through the horizontal elongated slot and are connected with the outer steel pipe through welding; and two horizontal core penetrating plates are located on the same side of the outer steel pipe. The horizontal core penetrating plated are adopted to connect a beam with a column, the stress of a beam flange is transmitted to the concrete filled steel tubular column, the structure is simple, the force transmission is clear, and meanwhile concrete pouring is facilitated.

Description

technical field [0001] The invention relates to the technical field of steel-concrete structures in construction engineering, in particular to a steel beam bolted node structure of a horizontal core-piercing steel pipe concrete column. Background technique [0002] In recent years, the state has adopted various policies to advocate the transformation of the construction industry to the direction of green energy conservation, and an important step is to promote the development of prefabricated buildings. The concrete-filled steel tube structure is one of the important systems of prefabricated buildings. The cross-section of the traditional concrete-filled steel tube column is much larger than the width of the inner wall, which causes problems such as external corners and column flutes in the interior, which affects the aesthetics. The width of the narrow-section concrete-filled steel tube column is less than or equal to that of the inner wall, and it can be "hidden in the wal...
