[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Referring to Figures 1-7 , a steel structure with good seismic performance of the present utility model includes a seat body and a steel structure column 3 installed on the seat body. When this structure is in use, according to the construction specifications of existing steel structure buildings, reinforced concrete is used as the foundation, and this structure is embedded in the reinforced concrete foundation so that the top surface of the base is exposed above the ground. The load-bearing column of the steel structure building is fixedly connected to the steel structure column 3 to resist the vibration effect when the ground vibrates and achieve a better seismic effect.

[0031] Among them, gaps are provided between the steel structure column 3 and the seat body in both the horizontal and vertical directions, and a buffer pad 6 for supporting the steel structure column 3 is arranged in the gaps. The buffer pad 6 is made of hard rubber. When an earthquake occurs, there are mainly longitudinal vibrations and lateral vibrations. The buffer pad 6 is used to buffer the transmission of longitudinal vibrations and lateral vibrations, so that when the steel structure vibrates, there is a certain moving space on the steel structure column 3, thereby avoiding the direct transmission of vibration energy to the steel structure and causing excessive external force on the steel structure and damage.

[0032] The steel structure column 3 includes a support sphere 301 and a support column body 302 welded to the top of the support sphere 301. Among them, a flange 303 is welded to the top of the support column 302. When in use, the load-bearing column of the steel structure building is also screwed and fixed to the flange 303 through a flange;

[0033] A buffer pad 6 is provided between the upper part of the supporting sphere 301 and the base, and between the outer wall of the supporting column 302 and the base. When longitudinal vibration occurs, the supporting sphere 301 makes a slight up-and-down displacement in the gap between it and the base. When lateral vibration occurs, the supporting column 302 can have a slight inclination offset with respect to the base, squeezing the shock-absorbing spring 604 to resist the vibration effect.

[0034] The seat body includes a base 1 and a cushion block 5. A hemispherical supporting groove 104 corresponding to the supporting sphere 301 is machined in the middle of the top of the base 1. The depth of the hemispherical supporting groove 104 is the radius value of the supporting sphere 301. During use, first place the supporting sphere 301 into the supporting groove 104.

[0035] One end of the cushion block 5 close to the steel structure column 3 is machined with a spherical surface groove 503 corresponding to the supporting sphere 301 and a cylindrical surface groove 504 corresponding to the supporting column 302. The buffer pad 6 is located between the spherical surface groove 503, the cylindrical surface groove 504 and the steel structure column 3.

[0036] The height of the spherical surface groove 503 is equal to the radius value of the supporting sphere 301, while the radius value of the spherical surface groove 503 is greater than the radius value of the supporting sphere 301. The radius value of the cylindrical surface groove 504 is greater than the radius value of the supporting column 302, so that a gap is formed between the spherical surface groove 503 and the supporting sphere 301, and a gap is also left between the cylindrical surface groove 504 and the outer wall of the supporting column 302. During use, the spherical surface groove 503 is buckled on the outside of the upper half of the supporting sphere 301, and the cylindrical surface groove 504 surrounds the outside of the supporting column 302.

[0037] The cushion block 5 includes a cushion block body 501. A cushion block bottom block 505 is integrally formed at the bottom of the cushion block body 501. A cushion block bottom groove 102 corresponding to the cushion block bottom block 505 is machined on the top of the base 1. During use, the cushion block bottom block 505 is inserted into the cushion block bottom groove 102 to initially install the cushion block 5 on the base 1, facilitating the positioning and installation of the cushion block 5.

[0038] The buffer pad 6 includes a spherical surface sealing pad 601 installed between the spherical surface groove 503 and the supporting sphere 301, and a cylindrical surface shock-absorbing pad 602 installed between the cylindrical surface groove 504 and the supporting column 302. The spherical surface sealing pad 601 is used to reduce the entry of foreign objects into the gap between the supporting groove 104 and the supporting sphere 301. The number of buffer pads 6 can correspond to or not correspond to the number of cushion blocks 5. During use, first stick the buffer pad 6 on the surface of the steel structure column 3, and then install the cushion block 5 to compress the buffer pad 6.

[0039] The cylindrical shock pad 602 includes an outer ring 603 and an inner ring 605 that are concentrically arranged. The outer ring 603 and the inner ring 605 are connected together by shock springs 604. During use, the outer ring 603 is welded and fixed to the bump 506, and the inner ring 605 is welded and fixed to the steel structure column 3. When vibration occurs, the shock springs 604 are used to absorb the kinetic energy generated by the swaying of the steel structure, reduce the resonance of the steel structure, and improve the seismic performance of the steel structure.

[0040] The peripheral side walls of the cylindrical shock pad 602 are wrapped with rubber pads to prevent foreign objects from entering between the outer ring 603 and the inner ring 605.

[0041] There are multiple spacer blocks 5, and the multiple spacer blocks 5 are spliced together to enclose the outside of the steel structure column 3.

[0042] The spacer block 5 is processed with a second bolt hole 502. The second bolt hole 502 vertically penetrates the top seat body 201 and the spacer block body 501. The base 1 is processed with a first bolt hole 103 corresponding to the second bolt hole 502. A fixing bolt 4 is screwed into the second bolt hole 502 and the first bolt hole 103 to press down the spacer block body 501 with the fixing bolt 4 and screw and fix the top seat body 201 and the base body 101 together.

[0043] The top of the spacer block 5 is detachably installed with a top seat 2. The top seat 2 is processed with a third bolt hole corresponding to the second bolt hole 502. The fixing bolt 4 is installed on the top seat 2. During use, the fixing bolt 4 passes through the third bolt hole, the second bolt hole 502, and the first bolt hole 103 to screw and fix the top seat 2.

[0044] In this application, a bump 506 is integrally formed at one end of the top of the spacer block body 501 close to the steel structure column 3. The cylindrical groove 504 is located on the end face of the bump 506 close to the steel structure column 3. The steel structure column 3 is located above the spherical groove 503. The top seat 2 includes a top seat body 201, an intermediate sleeve hole 202, and a spacer block groove 203. The inner wall size of the intermediate sleeve hole 202 corresponds to the outer wall size of the bump 506, and the horizontal size of the inner wall of the intermediate sleeve hole 202 is larger than the radial size of the flange 303.

[0045] In this application, it is optional to enclose the outside of the steel structure column 3 with four spacer blocks 5. When installing the top seat body 201, the intermediate sleeve hole 202 is sleeved outside the four bumps 506, and one end of the spacer block body 501 away from the steel structure column 3 is located in the spacer block groove 203.

[0046] Working principle: Before using this structure, first place the supporting sphere 301 into the supporting groove 104, stand the steel structure column 3 on the base body 101, then attach the buffer pad 6 to the surface of the steel structure column 3, and then place the four cushion blocks 5 into the cushion block bottom groove 102 in sequence. Use the cushion block body 501 to press the buffer pad 6 and support the steel structure column 3. Finally, from top to bottom, pass the steel structure column 3 through the middle sleeve hole 202, and put the top seat body 201 on the tops of the base body 101 and the cushion block body 501, and the outer wall of the convex block 506 is engaged with the inner wall of the middle sleeve hole 202. Then tighten the fixing bolt 4, which is convenient for assembly;

[0047] During use, according to the construction specifications of existing steel structure buildings, use reinforced concrete to make the foundation, and embed this structure in the reinforced concrete foundation, so that the top surface of the top seat body 201, the upper part of the support column body 302, and the flange 303 are exposed above the ground, and fixedly connect the load-bearing column of the steel structure building with the steel structure column 3;

[0048] When the steel structure shakes due to vibration; the supporting sphere 301 rotates slightly in the supporting groove 104, and the support column body 302 makes a slight swing with the center of the supporting sphere 301 as the center point. At this time, the support column body 302 squeezes the shock-absorbing spring 604 in the swinging direction, and the shock-absorbing spring 604 absorbs the kinetic energy generated by the shaking, achieving better seismic performance.
