Connecting joint structure of steel pipe column and side wall invading into side wall

Abstract

The invention provides a connecting joint structure of a steel pipe column and a side wall invading into the side wall. The connecting joint structure comprises the steel pipe column and the side wall, wherein at least two rows of horizontal steel bars are arranged in the side wall and are respectively close to the surfaces of two sides of the side wall; the steel pipe column invades into the side wall, so that one row of steel bars are broken at the invading part of the steel pipe column; a connecting plate which is connected with the broken steel bars in parallel is arranged on the steel pipe column; a T-shaped plate is also connected to the steel pipe column; a web plate of the T-shaped plate is perpendicular to the side wall; and one end of the web plate is connected with the top of the steel pipe column invading into the side wall, and the other end of the web plate is perpendicularly connected with a flange of the T-shaped plate. The connecting joint structure has the characteristics that the steel pipe column and the side wall are integrally deformed, the force transmission of the steel bars of the side wall is coherent, the structure of the steel pipe column is complete and the like, and the integral safety and stability of a wall column component can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of structural engineering design, and particularly relates to a connection node structure of a concrete-filled steel tube column and a reinforced concrete side wall intruding into the side wall. Background technique [0002] With the development of urban rail transit, some large-scale underground hub projects have gradually begun to use concrete-filled steel tubular columns with higher bearing capacity for design. However, due to the particularity of the underground structure, reinforced concrete side walls must be installed near the soil to resist water and soil pressure. At the same time, under the influence of traffic, environment, construction methods, investment and other factors, the outer contour of the underground project is greatly limited, and it is inevitable to begin with The occurrence of side-span steel pipe columns intruding into reinforced concrete side walls. The connection between the steel pipe col...

Problems solved by technology

However, due to the particularity of the underground structure, reinforced concrete side walls must be installed near the soil to resist water and soil pressure. At the same time, under the influence of traffic, environment, construction methods, investment and other factors, the outer contour of the underground project is greatly restricted, and it is inevitable at the beginning The occurrence of side-span steel pipe columns intruding into the reinforced concrete side wall

The joints between the steel pipe column and the side wall are prone to structural incongruity, deformation, unstable force transmission, etc., and the structural safety needs to be improved
