Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a sliding connection structure between a masonry wall and a main structure steel column. Background Art

[0002] The masonry structure is one of the main building structure forms. Due to the disadvantages of low material strength, poor ductility, weak integrity, etc. of the masonry structure, the seismic performance of the masonry structure is poor. Therefore, in construction engineering, the masonry wall and the main structure steel column are usually reliably tied to ensure the seismic performance and stability of the masonry wall.

[0003] At present, most of the masonry walls and the main structure steel columns adopt a rigid tie form. However, this rigid tie structure will cause sudden changes in stiffness and strength distribution on the steel structure, which has an adverse impact on the earthquake resistance of the main structure. Summary of the Utility Model

[0004] Aiming at the above defects, the technical problem to be solved by the utility model is to provide a sliding connection structure between a masonry wall and a main structure steel column to solve the problem that the existing technology using a rigid tie form has an adverse impact on the earthquake resistance of the main structure.

[0005] To this end, the first aspect of the embodiments of the present application provides a sliding connection structure between a masonry wall and a main structure steel column for tying between the main structure steel column and the masonry walls on both sides, including:

[0006] An anchor bolt is embedded in the masonry wall, and the outer end of the anchor bolt extends out of the surface of the masonry wall;

[0007] A connecting steel plate is provided with an oblong hole. Two connecting steel plates are respectively symmetrically welded and fixed on both sides of the main structure steel column, and the inner side surface of the connecting steel plate is flush with the inner side surface of the main structure steel column; the outer end of the anchor bolt passes through the oblong hole on the connecting steel plate and is fixed by a nut and a gasket;

[0008] A plastic sliding sheet is arranged between the masonry wall and the main structure steel column and the connecting steel plate.

[0009] Based on the above technical solutions, a sliding connection structure is used to tie between the masonry wall and the main structure steel column, replacing the rigid connection structure of the existing technology. During an earthquake, sliding can occur between the masonry wall and the main structure steel column to relieve the destructive force of the earthquake and avoid damaging the masonry wall.

[0010] In the above technical solution, preferably, two layers of plastic sliding sheets are provided. In this implementation manner, the sliding performance is further improved.

[0011] In the above technical solution, preferably, the inner end of the anchor bolt is bent. The fixing strength of the anchor bolt is improved.

[0012] In the above technical solution, preferably, the main structural steel column is made of I-shaped steel. The thickness of the connecting steel plate is less than the thickness of the flange of the I-shaped steel. This saves the material of the connecting steel plate and reduces the cost.

[0013] In the above technical solution, preferably, the connecting steel plate is rectangular, the plastic sliding sheet is also rectangular, and the outer edge of the plastic sliding sheet protrudes from the side of the connecting steel plate. This ensures that the connecting steel plate will not separate from the plastic sliding sheet during sliding.

[0014] As can be seen from the above technical solution, the sliding connection structure of the masonry wall and the main structural steel column provided by the present invention solves the problem that the rigid connection form in the prior art has an adverse impact on the seismic resistance of the main structure. Compared with the prior art, the present invention has the following beneficial effects:

[0015] A long hole is provided on the connecting steel plate, and the outer end of the anchor bolt passes through the long hole on the connecting steel plate and is fixed by a nut and a gasket. During an earthquake, the anchor bolt can move in the long hole, so that a sliding can occur between the masonry wall and the main structural steel column, eliminating the problem of sudden changes in the stiffness and strength of the overall structure caused by the rigid connection between the masonry wall and the steel structure, being able to reduce the earthquake hazard and ensure the seismic fortification goal of the main structure.
