[0025] like Figures 1 to 5 As shown, the present invention provides a seismic-resistant structure for a subway station, comprising a seismic-resistant frame 100, wherein a plurality of first support assemblies 200 are provided at the bottom of the seismic-resistant frame 100 and connected to the ground 101, wherein:

[0026] Each group of first supporting components 200 is provided with a first fixing member, which is a U-shaped structure formed by connecting a first horizontal plate 201 and first vertical plates 202 on both sides. Two first rotating shafts 203 are vertically connected between the two first vertical plates 202. A through hole is opened on the first horizontal plate 201, and a first telescopic rod 204 is movably inserted into the through hole. The top of the first telescopic rod 204 is hinged with two first connecting plates 205 in parallel. The top of each first connecting plate 205 is hinged with an L-shaped first clamping plate. Each first clamping plate is composed of a first clamping arm 206 and a second clamping arm 207. The bent portion of each first clamping plate is rotatably sleeved on the outer periphery of any first rotating shaft 203. The two first clamping plates are symmetrical to each other. The first clamping arms 206 of the two first clamping plates are close to each other, and the second clamping arm 207 extends out of the top of the first fixing member. The bottom of the first telescopic rod 204 is connected with a first spring 208;

[0027] The second clamping arms 207 of the two first clamping plates of each set of first support assemblies 200 clamp the bottom of the earthquake-resistant frame 100 , and the first fixing member together with the first telescopic rod 204 and the first spring 208 are located below the ground 101 .

[0028] In the present technical solution, the seismic structure of the subway station is provided with a seismic frame 100. The seismic frame 100 can be used directly or the outer layer can be poured with concrete to form a seismic wall. A plurality of first support assemblies 200 are provided at the bottom of the seismic frame 100. Each group of first support assemblies 200 is provided with two first clamping plates for clamping the bottom of the seismic frame 100. Each first clamping plate is an L-structure, which is vertically connected by a first clamping arm 206 and a second clamping arm 207. The two second clamping arms 207 are relatively located on both sides of the seismic frame 100. The two first clamping arms 206 are located in the first fixing member and are close to each other. The first fixing member includes The first horizontal plate 201 and the two upwardly extending first vertical plates 202 connected to the two ends thereof, two first rotating shafts 203 are provided at the two ends above the inner walls of the two vertical plates, the first clamping arms 206 and the second clamping arms 207 of the two first clamping plates are movably sleeved on the outer periphery of the first rotating shaft 203 at the connection point, so that the first clamping plates can rotate around the axis, the free end of each first clamping arm 206 is hinged to the first connecting plate 205, the free ends of the two first connecting plates 205 are hinged to the top of the first telescopic rod 204, the hinged parts of the two are parallel to each other, the first telescopic rod 204 moves through the first horizontal plate 201, and is coaxially connected to the first spring 208 at its end. During construction, the ground 101 is opened, and the first fixing member, along with the first clamping arm 206 of the first clamping plate, the first rotating shaft 203, the first connecting plate 205, the first telescopic rod 204, the first spring 208, and other structures, are placed within the opening in the ground 101, with the bottom of the first spring 208 abutting the bottom wall of the opening and the second clamping arm 207 extending out of the ground 101. The seismic frame 100 is then vertically placed above the plurality of first support assemblies 200, with the two first clamping arms 206 clamping the two sides of the seismic frame 100 relative to each other. During an earthquake, the seismic frame 100 shakes, and the first spring 208 contracts under the buffering force, pressing the first telescopic rod 204 downward, pulling the two first clamping plates inward, and thus bringing the two second clamping arms 207 closer together, further clamping the seismic frame 100, thereby stabilizing the seismic frame 100. At the same time, the elastic action of the spring acts as a buffer for the seismic frame 100, improving its earthquake resistance.

[0029] In another technical solution, the bottom of the earthquake-resistant frame 100 is further provided with multiple groups of second support assemblies 210 connected to the ground 101, wherein:

[0030] The second support assembly 210 of each group includes a second fixing member, which is a U-shaped structure formed by connecting a second horizontal plate 211 and second vertical plates 212 on both sides. Two second rotating shafts 213 are vertically connected between the two second vertical plates 212. A hole is opened on the second horizontal plate 211, and a second telescopic rod 214 is movably inserted into the hole. Two fixing plates 215 extending vertically outward are relatively provided at the top of the side wall of the second telescopic rod 214. The outer ends of the two fixing plates 215 are hinged to a second connecting plate 216. The top of each second connecting plate 216 is hinged to a second splint. Each second splint is composed of a first swing arm 217 and a second swing arm 218. The connecting parts of the two swing arms are rotatably sleeved on the outer periphery of the two second rotating shafts 213. The two second splints are symmetrical to each other. The first swing arms 217 of the two second splints are away from each other, and the second swing arm 218 extends out of the top of the second fixing member. The bottom of the second telescopic rod 214 is connected to a second spring 219.

[0031] The second swing arms 218 of the two second clamping plates of each set of second support assemblies 210 clamp the bottom of the earthquake-resistant frame 100 , and the second fixing member together with the second telescopic rod 214 and the second spring 219 are located below the ground 101 .

[0032] In the present technical solution, a plurality of second support assemblies 210 are further provided at the bottom of the seismic-resistant frame 100. The second support assemblies 210 have a similar structure to the first support assemblies 200, and are provided with a second fixing member, a second telescopic rod 214, and a second rotating shaft 213. The difference is that fixed plates 215 extending outward are relatively arranged on both sides of the top end of the second telescopic rod 214, and the first swing arms 217 of the second clamping plates arranged on the outer periphery of the two second rotating shafts 213 are away from each other in an eight-shaped shape. The two second swing arms 218 extend upward beyond the second fixing member and are clamped on both sides of the seismic-resistant frame 100. The lower ends of the two first swing arms 217 are hinged to the two second connecting plates 216, and the lower ends of the two second connecting plates 216 are hinged to the two fixed plates 215. During construction, the ground 101 is opened, and the second fixing member as a whole, together with the second swing arm 218 of the second clamping plate, the second rotating shaft 213, the second connecting plate 216, the second telescopic rod 214, the second spring 219 and other structures, are placed in the opening of the ground 101, so that the bottom of the second spring 219 abuts the bottom wall of the opening, and the second swing arm 218 extends out of the ground 101. The seismic frame 100 is placed vertically above the multiple second support assemblies 210, and the two first swing arms 217 are relatively clamped on both sides of the seismic frame 100. When an earthquake occurs, the seismic frame 100 shakes, and the second spring 219 is stretched by the buffering force, and the second telescopic rod 214 rises, pushing the two second clamping plates to swing outward, thereby bringing the two second swing arms 218 closer to each other, further clamping the seismic frame 100. The first support assembly 200 and the second support assembly 210 cooperate with each other. When affected by the longitudinal wave of an earthquake, the seismic anti-frame 100 swings up and down. The first support assembly 200 and the second support assembly 210 alternately clamp the seismic anti-frame 100 to achieve the purpose of stabilizing the seismic anti-frame 100. At the same time, the elastic effect of the spring acts as a buffer for the seismic anti-frame 100, thereby improving the seismic resistance of the seismic anti-frame 100.

[0033] In another technical solution, the angle between the first swing arm 217 and the second swing arm 218 of each second clamping plate is an obtuse angle. In this technical solution, the two swing arms of the second clamping plate are connected at an obtuse angle, which ensures the clamping effect of the second clamping plate on the anti-seismic frame 100.

[0034] In another technical solution, multiple groups of first support assemblies 200 and second support assemblies 210 are arranged alternately and spaced apart. In this technical solution, the first support assemblies 200 and the second support assemblies 210 are arranged alternately at the bottom of the seismic resistant frame 100, which effectively buffers the upward and downward impact of earthquake longitudinal waves and effectively improves the seismic resistance of the seismic resistant frame 100.

[0035] In another technical solution, seismic assemblies are further provided on both sides of the seismic resistant frame 100 and connected to the side walls 301. Each seismic resistant assembly includes two mutually symmetrical semi-elliptical buffers 302, with a plurality of first connecting members 303 connected between the two buffers 302. Each seismic resistant assembly is pre-embedded in the side wall 301 and connected to both sides of the seismic resistant frame 100 via a plurality of second connecting members 304. In this technical solution, the buffers 302 are cast into the side walls 301. The buffers 302 are two relatively connected semi-elliptical structures with a cavity formed in the middle, which makes their connection with the side walls 301 more stable and has a good buffering and seismic resistance effect against the left and right shaking caused by the shear waves of the earthquake.

[0036] In another technical solution, each buffer member 302 is made of steel. In this technical solution, the buffer member 302 is made of bent steel to improve structural stability.

[0037] In another technical solution, the seismic frame 100 comprises a steel frame, with multiple diagonally or vertically extending reinforcement rods 102 connected therein. In this technical solution, the seismic frame 100 is made of steel and can be rectangular or arched to accommodate the actual construction environment of a subway station. The seismic frame 100 can be used directly or can be poured with concrete on the outer layer to form a seismic wall. Multiple vertically or horizontally extending reinforcement rods 102 are connected and installed therein to provide structural stability to the seismic frame 100.

[0038] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
