The utility model realizes the convenience of adjusting the length of the steel structure through the driving worm, bidirectional screw, worm gear center plate and extension plate, and is suitable for different occasions. The curved plate, buffer frame, buffer plate and buffer spring are used to achieve buffering while providing strong supporting force, thereby improving the seismic resistance of the support. The support legs and fixed plates are used to fix the device to the ground or wall to improve the stability of the steel structure;

[0004] However, the above method still has the following defects in actual use: given the limited ability of the spring to absorb energy under strong earthquakes, the structure may suffer significant deformation and damage under strong earthquakes, which will have a negative impact on its stability and reliability. Utility Model Content

[0005] The utility model aims to provide a seismic-resistant hyperbolic steel frame structure to solve the problem in the above-mentioned background technology that the spring has limited ability to absorb energy under strong earthquakes and may be greatly deformed and damaged under strong earthquakes.

[0012] As a preferred technical solution of the utility model, a mounting hole is provided on the surface of each mounting plate.

[0013] Compared with the related art, the earthquake-resistant hyperbolic steel frame structure provided by the utility model has the following beneficial effects:

[0014] 1. In order to ensure that the hyperbolic steel frame structure is not prone to large deformation and damage under strong earthquakes, a number of triangular frames are set on the inner walls of the two curved steel plates through connecting columns. The triangular frames have good anti-deformation and anti-damage performance, high bearing capacity and rigidity. At the same time, connecting rods are set inside to enable them to withstand large external loads. A fixed frame is set between two adjacent triangular frames. The fixing rods inside the fixed frame increase the stability of the connection, making it more firm and reliable;

[0015] 2. In order to increase the firm strength of the connection between the two curved steel plates, a number of reinforcing ribs are arranged inside the reinforcement frame through the reinforcement plate. The reinforcing ribs have good ductility and can undergo certain plastic deformation during the force process, thereby absorbing energy and improving the seismic performance of the structure. At the same time, reinforcement rods are arranged on the surface of the reinforcement frame to improve the surface support performance. BRIEF DESCRIPTION OF THE DRAWINGS
