[0003] For example, the Chinese patent with publication number CN213654404U discloses a construction steel structure with seismic buffering function, including an external steel structure body, the lower surface of the external steel structure body is respectively fixedly connected with steel structure support legs, the lower end of the steel structure support leg is provided with a placement base, the steel structure support leg is located inside the placement base and fixedly connected with a connecting base at one end, a spring is fixedly connected between the lower surface of the connecting base and the bottom inner wall of the placement base, a rotating block is fixedly connected to the connecting base, a connecting rod is rotatably connected to the rotating block, and a supporting rotating block is fixedly connected to the bottom inner wall of the placement base. The construction steel structure with seismic buffering function effectively reduces the vibration force on the external steel structure body, avoids damage to the external steel structure body, and also ensures the safety of personnel in the external steel structure body.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the rotation range of the connecting rod in the above device is limited, which further leads to the limited shock-absorbing effect of the overall device, and can only buffer smaller vibrations, and the scope of use is limited. In view of this, we propose a steel structure with a seismic-resistant structure. Utility Model Content
