[0026] The present invention will be further described in detail below with reference to specific embodiments.
[0027] Please see Figure 1-5 This embodiment provides a bottom mounting kit for a steel structure column, including a base 1, a supporting steel structure column 2 on the outside of the base 1, and a shock-absorbing structure 3 and an auxiliary fixing structure 4 between the base 1 and the supporting steel structure column 2.
[0028] The base 1 has a mounting groove that runs through it, and extension grooves are provided on both sides of the mounting groove. The shock-absorbing structure 3 includes a mounting block 301, which is a cubic block. The top two sides of the mounting block 301 have outwardly protruding lugs 311. Part of the mounting block 301 is located in the mounting groove, and the bottom of the mounting block 301 extends outward from the bottom of the base 1 through the mounting groove. The lugs 311 are inserted into the extension grooves. The top of the mounting block 301 has a recessed movable groove 315, and the vertical cross-section of the movable groove 315 is rectangular. When the lugs 311 are inserted into the extension grooves, the mounting groove is sealed by a cover plate 316, and the mounting groove opening is sealed by connecting bolts 317 that pass through the cover plate 316, the mounting block 301, and the base 1 in sequence, and then fixed by nuts. The cover plate 316 has a through groove that matches the support block 306, so that the support block 306 can extend out of the base 1 from the lifting plate 305 to support and fix the steel structure column 2. The support block 306 is a cubic structure fixed to the mounting plate. The number of connecting bolts 317 connecting the cover plate 316, the mounting block 301 and the base 1 is four. The four bolts are arranged in a rectangle to connect and fix the cover plate 316, the mounting block 301 and the base 1, ensuring that the cover plate 316, the mounting block 301 and the base 1 are firmly connected.
[0029] The auxiliary fixing structure 4 includes multiple reinforcing ribs 401, which are evenly fixed to the bottom of the mounting block 301 and extend outwards towards the bottom of the base 1. The auxiliary fixing structure 4 also includes four triangular support plates 402, each supporting the sidewalls of the steel column 2 and surrounding the column 2. Each triangular support plate 402 has a horizontal plate 403 on both sides, which is fixedly connected to the base 1 by fixing bolts 404. The triangular support plates 402 are supported by abutting against the sidewalls of the steel column 2. By providing reinforcing ribs 401, the stability of the overall structure after installation on the ground is increased. The four triangular support plates 402 are installed using fixing bolts 404, providing auxiliary restraint for the steel column 2, thereby increasing the overall structural stability and fixing the mounting block 301.
[0030] The damping structure 3 also includes a spring damper 310 and a lifting plate 305. The movable groove 315 has groove segments with different widths. The width of the groove segment at the bottom of the groove is smaller than the width of the groove segment at the opening, that is, the groove segment at the opening and the groove segment at the bottom of the groove form a step. The edge of the groove opening is provided with a limiting block 314 extending towards the center of the groove opening. The end plane of the limiting block 314 extending towards the center of the groove opening is flush with the side wall of the bottom of the groove. The limiting block 314 corresponds to the step. The area between the limiting block 314 and the step forms the installation area 312 of the first buffer component, that is, both side walls of the groove segment at the opening are... The system includes an installation area 312 with a first buffer component; a lifting plate 305 is slidably connected to a movable groove 315, the width of which corresponds to the groove segment of the movable groove 315, meaning the lifting plate 305 can only slide within the groove segment of the movable groove 315 and is restricted by a limiting block 314 from sliding out of the installation block 301; a spring damper 310 is disposed between the lifting plate 305 and the bottom of the movable groove 315, with both ends of the spring damper 310 fixedly connected to the bottom of the lifting plate 305 and the bottom of the movable groove 315, respectively. A support block 306 is fixed to the top of the lifting plate 305, supporting the bottom of the steel structure column 2. The spring damper 310 is a device that uses elastic deformation to generate damping effect. Its main function is to consume vibration energy, making the vibration of machines or structures smooth. The main uses of the spring damper 310 include vibration reduction and buffering, motion control, energy absorption and dispersion, and protection of structures and equipment. Therefore, by utilizing the characteristics of the spring damper 310, it can buffer and absorb vibration forces when the steel structure column 2 is subjected to them. Specifically, a shock-absorbing rubber plate 313 is installed between the spring damper 310 and the lifting plate 305.
[0031] The shock absorption structure 3 also includes a first buffer assembly and a second buffer assembly. The first buffer assembly is installed in the mounting area 312 of the first buffer assembly between the limiting block 314 and the lifting plate 305. The first buffer assembly includes an extension sleeve 302, a tension spring 303 and an extension rod 304. One end of the extension sleeve 302 is fixedly connected to the bottom of the limiting block 314, and one end of the extension rod 304 is fixedly connected to the top of the lifting plate 305. The other end of the extension rod 304 is inserted into the extension sleeve 302 and is slidably connected relative to the extension sleeve 302. The two ends of the spring are respectively connected to the extension rod 304 and the extension sleeve 302. The spring is located inside the extension sleeve 302 and between the extension rod 304 and the extension sleeve 302.
[0032] A second buffer assembly is provided between the lifting plate 305 and the bottom of the movable groove 315. The second buffer assembly includes a sliding rod 318, a base block 307, a shock-absorbing spring 308, and a hinge rod 309. The base block 307 is fixed between the spring damper 310 and the bottom of the movable groove 315. There are two sliding rods 318, two shock-absorbing springs 308, and two hinge rods 309. The two sliding rods 318 are symmetrically fixed on both sides of the base block 307. One end of each of the two hinge rods 309 is slidably connected to the two sliding rods 318, and the other end of each hinge rod 309 is hinged to the lifting plate 305. The two hinge rods 309 are symmetrically distributed along the base block 307. The two shock-absorbing springs 308 are respectively sleeved on the two sliding rods 318. The shock-absorbing springs 308 are located between the base block 307 and the hinge rods 309. The two ends of the shock-absorbing springs 308 are fixedly connected to the base block 307 and one end of the hinge rod 309, respectively.
[0033] When implementing this procedure, please follow these steps:
[0034] 1) When subjected to vibration, the tension spring 303 will extend appropriately, causing the extension rod 304 and the lifting plate 305 to descend appropriately;
[0035] 2) Then, the lifting plate 305 drives the support block 306 and the steel structure column 2 downward, and absorbs or weakens part of the vibration force through the shock-absorbing rubber plate 313 and the spring damper 310.
[0036] 3) The descent of the lifting plate 305 causes the hinge rod 309 to move along the sliding rod 318;
[0037] 4) The damping spring 308 is compressed by the hinge rod 309, thereby absorbing and weakening the remaining vibration force through the damping spring 308.
[0038] In summary, when the bottom mounting kit of the steel structure column is subjected to vibration, the tension spring 303 will extend appropriately, causing the extension rod 304 and the lifting plate 305 to descend appropriately, which in turn drives the support block 306 and the steel structure column 2 to move downward. During the descent of the lifting plate 305, it will first absorb or weaken part of the vibration force through the shock-absorbing rubber plate 313 and the spring damper 310. Then, during the descent of the lifting plate 305, it will drive the hinge rod 309 to move along the sliding rod 318 and compress the shock-absorbing spring 308, thereby absorbing and weakening the vibration force again through the shock-absorbing spring 308, thus achieving the purpose of shock absorption.
