Internally reinforced square pipe column body joint and installation method thereof

Abstract

The invention provides an internally reinforced square pipe column body joint and an installation method thereof, and belongs to the field of steel structures. According to the internally reinforced square pipe column body joint and the installation method thereof, the problem of low strength of existing square pipe column body joints is solved. The internally reinforced square pipe column body joint comprises a column body, a square-pipe-shaped internally reinforced pipe, a locating piece and a compression spring. The column body comprises four column plates, and the square-pipe-shaped internally reinforced pipe is embedded in the column body in a matched mode. The internally reinforced pipe is sleeved with the column body in a matched mode, the internally reinforced pipe comprises four internally reinforced plates, and a lifting ring is fixed to the inner side face of one of the internally reinforced plates. A plurality of connecting holes are formed in the column plates, and a plurality of reinforced holes are formed in the internally reinforced plates. The locating piece comprises a locating rod and a locating pipe, wherein the locating rod is sleeved with the locating pipe, anexternal thread is arranged on the outer wall of the front end of the locating pipe, the front end of the locating pipe is connected to the outer end of one of the connecting holes in a threaded mode, and a spring groove is formed in the inner wall of the locating pipe. A moving block is arranged on the rod wall of the locating rod, and the locating rod is sleeved with the compression spring. Theinternally reinforced square pipe column body joint can achieve later reinforcement.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to an internally reinforced square tube cylinder node and an installation method thereof. Background technique [0002] In the steel structure buildings that are widely used at present, it is usually necessary to install the beam body on the side of the column. If the column is a closed member such as a square tube, a square tubular external reinforcing tube is generally placed on the outside of the column to strengthen the structure of the node. , during construction, fixing the end of the beam body on the external reinforcing tube can significantly improve the beam-column connection structure, but the external reinforcing tube on the outside of the column is limited by the column itself. Putting the external reinforcing tube, or only cutting the middle of the cylinder, and then inserting the external reinforcing tube can not play the role of strengthening the strength of th...

[0002] In the steel structure buildings that are widely used at present, it is usually necessary to install the beam body on the side of the column. If the column is a closed member such as a square tube, a square tubular external reinforcing tube is generally placed on the outside of the column to strengthen the structure of the node. , during construction, fixing the end of the beam body on the external reinforcing tube can significantly improve the beam-column connection structure, but the external reinforcing tube on the outside of the column is limited by the column itself. Set the external reinforcing tube, or only cut the middle of the cylinder, and then insert the external reinforcing tube, which can not play the role of strengthening the joint strength, and the joint is easy to be damaged, so it is necessary to improve
