Description

Technical Field

[0001] This utility model relates to the field of building steel structure technology, specifically to a seismic-resistant building steel structure. Background Technology

[0002] Steel structures are structural systems composed primarily of steel components (such as beams, columns, and trusses) used to support and bear the loads of buildings. Steel structures offer advantages such as high strength, light weight, good ductility, short construction periods, and industrial production capabilities, and are widely used in high-rise buildings, factories, bridges, stadiums, and other projects.

[0003] Existing steel structures used in seismic applications commonly suffer from problems such as excessive rigidity in node connections, simplistic energy dissipation structures, and complex component assembly. These issues lead to insufficient structural ductility under seismic loads, making them prone to brittle failure or permanent deformation, and resulting in difficult and costly post-earthquake repairs. Particularly in multi-story or composite structures, the lack of efficient energy absorption and buffering mechanisms between beams and columns makes it difficult to simultaneously meet structural strength requirements while dispersing and automatically resetting seismic impacts.

[0004] Therefore, it is necessary to design a seismic-resistant steel structure for buildings to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant steel structure for buildings, comprising two columns, with a second horizontal column and two first horizontal columns slidably inserted between the two columns. Each of the two first horizontal columns and one second horizontal column has a connecting block fixed to both ends. A first connecting column is slidably inserted into the interior of each of the three connecting blocks on the same side. A mounting plate is fixedly attached to the top of each of the two first connecting columns. The mounting plate is threadedly bolted to the top of the upper first horizontal column. Connecting square openings are provided on all four sides of each of the two columns. Furthermore, each of the two columns has a groove above the multiple square insertion openings at the top.

The first U-shaped block is rotatably fitted with a second rotating block. The bottom end of the second rotating block is fixed with a second insertion post. The bottom end of the second insertion post is fixed with a honeycomb sheet. The second U-shaped block is rotatably fitted with a first rotating block. The first rotating block has a liquid filling groove inside, and a spring is fixed inside the liquid filling groove.

[0007] Preferably, a sealing ring is fixedly connected to the top of the first rotating block, and the inner wall of the sealing ring is in contact with the outer surface of the second insertion post, and the second insertion post is slidably disposed inside the sealing ring.

[0008] Preferably, the outer surface of the first rotating block is connected to a liquid inlet pipe, and the internal movable plug of the liquid inlet pipe is equipped with a piston, and the honeycomb sheet is slidably disposed inside the liquid filling tank.
