Embodiment Construction

[0013] The specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0014] First, weld the shear connector 2 on the inner side of the connecting steel plate 1. The shear connector 2 is arranged at least one row along the longitudinal direction of the connecting steel plate 1. The shear connector 2 can be made of Q235 or Q345 steel studs, channel steel or bent bar members . Then, the connecting steel plate 1 welded with the shear connector 2 and the steel pipe 3 of the circular steel pipe concrete column are connected by welding. At the construction site, after the steel pipe 3 in the circular steel tube concrete column is installed and positioned, the longitudinal reinforcement 4 in the reinforced concrete shear wall, the U-shaped horizontal distribution reinforcement 5 at the end and the horizontal distribution reinforcement 6 at the non-node are arranged, and the reinforcement is carried out. Binding and positioning, then...

Abstract

The invention provides a node connection method for a circular steel tube concrete column and a reinforced concrete shear wall, and belongs to the field of a building structure. By the method, the problem that when connected, the conventional connected circular steel tube concrete column and reinforced concrete wall cannot work synergically can be solved. The method comprises the following steps of: welding a connection steel plate on the connecting part of the circular steel tube concrete column with the reinforced concrete shear wall; welding a shearing resistant connection member in the connection plate; arranging a U-shaped horizontally distributed reinforcing steel bar at the end of the reinforced concrete shear wall; and casting concrete to make the shearing resistant connection member, the connection steel plate and the U-shaped reinforcing steel bar and concrete at the end of the reinforced concrete shear wall work together and stressed synergically. By the method, the bearingcapacity and the energy consumption capability of the structural system can be improved, so the breakage of the structure under the action of rare load can be avoided. During construction, no weldingworking capacity is provided, the convenient and quick construction is ensured, and the method has better economic benefit.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a node connection mode at the intersection of a circular steel pipe concrete column and a reinforced concrete shear wall. Background technique [0002] Circular concrete-filled steel tube columns and reinforced concrete shear walls are two commonly used structural components in high-rise buildings, especially as the height of buildings increases, reinforced concrete shear walls and circular steel-filled concrete frames are used in the structure at the same time, forming a circular Steel tube concrete frame-reinforced concrete shear wall structure, or circular steel tube concrete frame-reinforced concrete cylinder structure. In the structure, how to ensure the effective connection and joint work of the two is one of the urgent problems to be solved when the circular steel pipe concrete column and the reinforced concrete wall are used together. In previous engineerin...
