[0024] See also Figures 1 to 5 The present invention provides an anti-seismic device for soft soil foundation, comprising a plate body 1, two horizontal plates 2, two vertical plates 3, a cross plate 4, a first fixing ring 5, a second fixing ring 6, a column 7 and a connecting piece 8, wherein the two horizontal plates 2 and the two vertical plates 3 are connected to each other to form a tic-tac-toe support plate 9, the tic-tac-toe support plate 9 is fixedly connected to the plate body 1 and is located above the plate body 1, the cross plate 4 is fixedly connected to the tic-tac-toe support plate 9, and the end arm of the cross plate 4 is arranged at the connection between the horizontal plate 2 and the vertical plate 3, the first fixing ring 5 and the second fixing ring 6 are both arranged on the tic-tac-toe support plate 9 with the center of the tic-tac-toe support plate 9 as the center point, and the second fixing ring 6 is sleeved and enclosed on the outside of the first fixing ring 5, the number of the columns 7 is four, the four columns 7 are respectively fixedly connected to the plate body 1, and are respectively located at the bottom corners of each plate body 1, and the connecting piece 8 is arranged between each column 7 and the second fixing ring 6.

[0025] In this embodiment, the two horizontal plates 2 and the two vertical plates 3 are connected to each other to form a tic-tac-toe support plate 9, and the tic-tac-toe support plate 9 is fixed on the plate body 1, and then the end arm of the cross plate 4 is set at the connection between the horizontal plate 2 and the vertical plate 3, the first fixing ring 5 and the second fixing ring 6 are both set on the tic-tac-toe support plate 9 with the center of the tic-tac-toe support plate 9 as the center, and the second fixing ring 6 is sleeved and enclosed on the outside of the first fixing ring 5, the four columns 7 are respectively fixedly connected to the plate body 1, and are respectively located at the bottom corners of each plate body 1, and the connecting piece 8 is arranged between each column 7 and the second fixing ring 6. Through the above-mentioned structural arrangement, the structural strength of the foundation can be increased, and the seismic resistance of the foundation can be increased, so that the foundation structure is more stable, so that the building structure is supported by a device with good seismic resistance in a weak foundation, and serious engineering accidents can be avoided.

[0026] Furthermore, the anti-seismic device for soft soil foundation further includes a support column 10 , and the support column 10 is arranged between two adjacent columns 7 .

[0027] In this embodiment, the provision of the support column 10 can increase the structural strength between two adjacent columns 7, improve the overall structural stability of the device, and provide better anti-seismic performance.

[0028] Further, the anti-seismic device for soft soil foundation also includes a bottom plate 11 and four first anti-seismic components 12, the bottom plate 11 is arranged below the plate body 1, and the first anti-seismic component 12 is arranged at each bottom corner of the bottom plate 11. Each of the first anti-seismic components 12 includes an outer cylinder 13, an inner cylinder 14, a support block 15, a convex column 16 and a first elastic member 17, the outer cylinder 13 is fixedly connected to the bottom plate 11, the support block 15 is slidably connected to the outer cylinder 13 and is located inside the outer cylinder 13, the inner cylinder 14 is fixedly connected to the support block 15, the convex column 16 is fixedly connected to the support block 15 and is located at one end of the support block 15 away from the inner cylinder 14, one end of the first elastic member 17 is fixedly connected to the support block 15, the other end of the first elastic member 17 is fixedly connected to the inner top wall of the outer cylinder 13, and the first elastic member 17 is sleeved on the outside of the convex column 16.

[0029] In this embodiment, by setting the first seismic-resistant component 12, when subjected to vibration, the supporting block 15 slides inside the outer tube 13, thereby causing the boss 16 to move toward the inner top wall end close to the outer tube 13, and at the same time, the first elastic member 17 is compressed after being subjected to force, and the first elastic member 17 is deformed to improve the seismic resistance. If the shock force is too large, the boss 16 will be in contact with the inner top wall of the outer tube 13, and can also have a certain seismic resistance, thereby increasing the seismic resistance of the foundation, making the foundation structure more stable, and allowing the building structure to be supported by a device with good seismic resistance in a weak foundation, thereby avoiding serious engineering accidents.

[0030] Furthermore, each of the first anti-seismic components 12 further includes a buffer pad 18 , which is fixedly connected to the boss 16 and is located at an end of the boss 16 away from the abutment block 15 .

[0031] In this embodiment, when the boss 16 abuts against the inner top wall of the outer tube 13, the buffer pad 18 can play a certain role in buffering, thereby improving the seismic resistance of the device and increasing the seismic resistance of the foundation.

[0032] Furthermore, the bottom plate 11 has a groove 19, and the seismic device for soft soil foundation also includes a second seismic component 20, which is arranged between the plate body 1 and the bottom plate 11. The second seismic component 20 includes a fence 21, a frame 22, two connecting rods 23, two sliders 24 and two second elastic members 25. The fence 21 is fixedly connected to the plate body 1 and is located below the plate body 1. The fence 21 is provided with a slide groove 26. One end surface of the frame 22 is connected to the second elastic member 25. The enclosure 21 is slidably connected, and one end face of the frame 22 is located in the slide groove 26, and the other end face of the frame 22 is fixedly connected to the bottom plate 11. The two connecting rods 23 are symmetrically arranged in an eight-shaped shape, and one end of each connecting rod 23 is hinged to the plate body 1, and the other end of each connecting rod 23 is hinged to the corresponding slider 24. Each slider 24 is slidably arranged in the slot 19, and each slider 24 is connected to the side wall of the slot 19 through the second elastic member 25. The second anti-seismic component 20 also includes two movable bars 27, one end of the two movable bars 27 is hinged to each other, and the other end of the two movable bars 27 is hinged to the corresponding connecting rod 23. The second anti-seismic component 20 also includes a third elastic member 28, the two ends of the third elastic member 28 are respectively fixedly connected to the enclosure 21 and the frame 22, and the third elastic member 28 is located in the slide groove 26.

[0033] In this embodiment, by arranging the second anti-seismic component 20 between the plate body 1 and the base plate 11, when subjected to vibration, the frame body 22 further contracts to the inside of the enclosure 21, that is, the distance between the top of the frame body 22 and the inner top wall of the slide groove 26 is reduced, and the third elastic member 28 is compressed after being subjected to force, thereby playing an effective shock-absorbing and anti-seismic role. At the same time, the eight-shaped angle between the two connecting rods 23 is increased, and the angle between the two movable bars 27 is increased. The connecting rod 23 resists the corresponding slider 24 to slide in the groove body 19, and then the second elastic member 25 is compressed after being resisted by the slider 24, thereby reducing the vibration received, thereby increasing the anti-seismic property of the foundation, making the foundation structure more stable, and allowing the building structure to be supported by a device with good anti-seismic ability in a weak foundation, thereby avoiding serious engineering accidents.
