[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, as Figures 1-4 As shown, this utility model provides a seismic-resistant energy-saving steel structure, including a column 1 and a base plate 2. The base plate 2 is located directly below the column 1. Mounting holes 21 are provided at the four corners of the base plate 2. Connecting blocks 22 are fixedly installed at both ends of the upper middle part of the base plate 2. Transmission rods 23 are rotatably connected to the upper ends of the connecting blocks 22. Fixed sliding rods 24 are fixedly installed at both ends of the lower middle part of the column 1. Sliding sleeves 25 are slidably engaged on the surfaces of the two fixed sliding rods 24. Buffer springs 26 are sleeved on the outer sides of the two fixed sliding rods 24. The buffer springs 26 are located in the middle of the two sliding sleeves 25. The lower ends of the four sliding sleeves 25 are rotatably connected to the transmission rods 23 respectively. Dampers 27 are fixedly installed at the four corners of the upper middle part of the mounting holes 21. The upper ends of the four dampers 27 are fixedly connected to the lower ends of the column 1 respectively. Rock wool layer 18 is pasted on the upper end of the column 1.
[0023] The specific settings and functions of this embodiment are described in detail below. When vibration occurs, the column 1 will drive the two fixed sliding rods 24 to shake continuously. During this process, the two sets of transmission rods 23 and the two sets of sliding sleeves 25 will slide back and forth along the fixed sliding rods 24, making them move closer or further apart. This will cause the buffer spring 26 to contract or rebound, thereby achieving the effect of shock absorption. In conjunction with the four sets of internal dampers 27, the shaking force from the left and right and up and down can be effectively counteracted. While ensuring shock absorption, the rigidity of the steel structure is improved, ensuring that it will not collapse and making it safer. The through hole 17 opened in the middle of the column 1 can reduce the manufacturing cost of the column 1 and can distribute the load more evenly, avoiding excessive local stress.
[0024] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pre-set hole 11 is provided in the center of the upper and lower ends of the column 1, and a pre-set hole 12 is provided on both sides of the center of the upper and lower ends of the column 1. A connecting plate 13 is threaded around the upper and lower ends of the column 1. A fixing plate 14 is fixedly installed at one end of the connecting plate 13. Screws 15 are threaded on both sides of the center of the fixing plate 14. A hinge 16 is rotatably engaged in the center of the fixing plate 14. The screws 15 are threadedly connected to the pre-set hole 12, and the hinge 16 is rotatably engaged with the pre-set hole 11. A through hole 17 is provided in the center of the column 1. A rubber pad 19 is pasted at the connection between the connecting plate 13 and the fixing plate 14 and the column 1. The hinge 16 and the screws 15 pass through the rubber pad 19 respectively.
[0025] The overall effect of this embodiment is that by opening pre-set holes 11 and 12 around the upper and lower ends of the column 1, the device is easier and faster to assemble with the connecting plate 13. Furthermore, the screws 15 and hinge pins 16 allow the components to rotate relative to each other when subjected to external forces, thereby adapting to structural deformation requirements and improving the overall seismic performance and flexibility of the structure. When vibration occurs, the column 1 will drive the two fixed sliding rods 24 to shake continuously. During this process, the two sets of transmission rods 23 and the two sets of sliding sleeves 25 will slide back and forth along the fixed sliding rods 24, bringing them closer together or further apart. The buffer spring 26 can contract or rebound, thereby achieving a shock absorption effect. Together with the four sets of internal dampers 27, it can effectively counteract the swaying forces from the left, right and up and down. While ensuring shock absorption, it also improves the rigidity of the steel structure, ensuring its stability so that it will not easily collapse, thus giving it higher safety. Rubber pads 19 are also set at the connection between the connecting plate 13 and the fixing plate 14 and the column 1. The rubber pads 19 have good elasticity and damping characteristics, which can effectively reduce the transmission of vibration and reduce the deformation of the connecting plate 13 and the fixing plate 14 and the column 1 when vibration occurs.
[0026] The device's usage and working principle are as follows: By opening pre-set holes 11 and 12 around the upper and lower ends of the column 1, the device is easier and faster to assemble with the connecting plate 13. The screws 15 and hinge pins 16 allow the components to rotate relative to each other when subjected to external forces, thereby adapting to the deformation requirements of the structure and improving the overall seismic performance and flexibility of the structure. When vibration occurs, the column 1 will drive the two fixed sliding rods 24 to shake continuously. During this process, the two sets of transmission rods 23 and the two sets of sliding sleeves 25 will slide back and forth along the fixed sliding rods 24, bringing them closer or further apart. This allows the buffer springs 26 to contract or rebound, thereby achieving a shock absorption effect. In conjunction with the four sets of internal dampers 27, the shaking forces from the left, right, up, and down can be effectively counteracted. While ensuring shock absorption, the rigidity of the steel structure is improved, ensuring its stability and preventing it from easily collapsing, thus providing higher safety. The through hole 17 opened in the middle of the column 1 can reduce the manufacturing cost of the column 1 and distribute the load more evenly, avoiding excessive local stress.
