Description

Technical Field

[0001] This invention relates to the field of earthquake-resistant foundations, specifically a device that can be used for both foundation earthquake resistance and seismic resistance of seismic layers. Background Technology

[0002] An earthquake is a natural phenomenon caused by the rapid release of energy in the Earth's crust, generating seismic waves. The collision and compression between tectonic plates, causing faulting and fracturing along plate boundaries and within plates, is the primary cause of earthquakes. As a natural disaster, earthquakes pose a real threat to human safety, making earthquake-resistant construction essential.

[0003] Chinese Publication No. CN113863403A discloses a seismic reinforcement device for building foundations, comprising: a frame including a ground surface, with load-bearing columns inserted into the inner side of the ground surface; and a movable mechanism including a fixing block, a support rod, a fixing plate, a through rod, a rotating groove, a rotating rod, and a rubber plate, with the movable mechanism connected to the surface of the ground surface. This seismic reinforcement device for building foundations effectively buffers the swaying of load-bearing columns, thereby increasing the stability and strength of the load-bearing columns, improving the seismic resistance of the building foundation, preventing building collapse due to earthquakes, reducing or even avoiding earthquake damage, and protecting life and property. While the above solution effectively buffers the load-bearing columns through the movable mechanism, it only considers the buffering of the foundation and load-bearing columns, and does not take into account the issue that the swaying of the foundation during an earthquake makes high-rise buildings most susceptible to collapse first.

[0004] In summary, the present invention provides an earthquake-resistant foundation device to solve the above-mentioned problems. Summary of the Invention

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] This invention provides an earthquake-resistant foundation device, comprising:

[0030] The device has an outer plate 1, which includes a center of gravity block 2 inside. A metal ring 11 is fixedly connected to the top of the center of gravity block 2. A horizontal telescopic rod 31 is fixedly connected to one side of the metal ring 11. A fixed column 22 is fixedly connected to the inner wall of the top of the device outer plate 1. One end of the fixed column 22 away from the inner wall of the device outer plate 1 is fixedly connected to the top of the center of gravity block 2. A first spring 21 is sleeved on the fixed column 22. A telescopic base 13 is fixedly connected to the top of the center of gravity block 2. A first telescopic column 14 is slidably connected to the top of the first telescopic column 14. A top plate 15 is fixedly connected to the top of the first telescopic column 14. The top plate 15 is pushed against the top of the inner wall of the foundation by the action of the first telescopic column 14 driven by the telescopic base 13.

[0031] The lifting plate 3 has an inclined telescopic rod 32 fixedly connected to its bottom. The end of the inclined telescopic rod 32 away from the lifting plate 3 is slidably connected to the top of the outer plate 1 of the device. The function of the lifting plate 3 is to fix the top of the device.

[0032] Fixed plate 4, a second telescopic column 41 is fixedly connected to one side of the fixed plate 4, and the end of the second telescopic column 41 away from the fixed plate 4 is fixedly connected to one side of the outer plate 1 of the device. A second spring 42 is installed on the second telescopic column 41. The function of the fixed plate 4 is to make the two sides of the device firmly fixed to the inner wall of the foundation.

[0033] As one embodiment of the present invention: an arched hole is provided in the middle of the metal ring 11. The length and width of the arched hole are both greater than the length and width of the telescopic base 13. The main function of the arched hole is to provide installation space for the telescopic base 13, which solves the problem that the first telescopic column 14 will not cause obstruction when it retracts into the telescopic base 13.

[0034] As one embodiment of the present invention: a square notch is provided at the top of the outer plate 1 of the device. The width of the square notch is greater than the width of the telescopic base 13. The square notch is mainly used to provide installation space for the metal ring 11, which solves the problem that the fixing ring at the bottom of the lifting plate 3 will not be blocked when it slides down and gets stuck on the metal ring 11.

[0035] As one embodiment of the present invention: a square hole is provided in the middle of the lifting plate 3, the length and width of the square hole are the same as those of the telescopic base 13, the lifting plate 3 is slidably connected to the outer wall of the telescopic base 13, and the square hole allows the lifting plate 3 to slide on the outer wall of the telescopic base 13.

[0036] As one embodiment of the present invention: a fixing ring 33 is fixedly connected to the bottom of the lifting plate 3. The length and width of the fixing ring 33 are both greater than the length and width of the metal ring 11. When the top plate 15 descends onto the lifting plate 3 under pressure, the lifting plate 3 will move downward until the fixing ring 33 at the bottom of the lifting plate 3 is stuck on the metal ring 11.

[0037] As one embodiment of the present invention: a slide rail is fixedly installed on the top of the outer plate 1 of the device, and one end of the oblique telescopic rod 32 is slidably connected to the slide rail. The slide rail is mainly used to allow the oblique telescopic rod 32 to slide.

[0038] As one embodiment of the present invention: a square groove 151 is provided on the top of the outer plate 1 of the device. The square groove 151 is the same size as the top plate 15. When the top plate 15 receives pressure, the square hole will descend into the square groove 151 on the lifting plate 3.

[0039] In one embodiment of the present invention: the bottom of the outer plate 1 of the device is slidably connected to a base plate 12, and the bottom of the base plate 12 is slidably connected to an unfolding piece 16. The unfolding piece 16 is in an unfolded state when placed in the foundation or seismic layer, and is used to fix the bottom.

[0040] Specific working principle:

[0041] like Figure 1-4As shown, this invention involves installing the device in the load-bearing columns of the foundation or in the seismic layer. Multiple second telescopic columns 41 extend to push the fixing plate 4 against the inner wall of the foundation or seismic layer, fixing both sides of the plate inside the foundation. As the telescopic base 13 drives the first telescopic column 14 to push the top plate 15 upward, the top plate 15 will be pressed against the top of the foundation. The unfolding piece 16 unfolds and fixes the bottom. Then the entire device is fixed inside the foundation. In reality, during the construction process, the basic shape of the foundation is first enclosed with wooden boards, then poured and shaped. After the foundation is shaped, the device is placed inside, and then the top is sealed.

[0042] In the case of low magnitude earthquakes, most buildings will not collapse, but it is unavoidable to feel the vibration. The present invention fixes the center of gravity block 2 inside the outer plate 1 of the device. When shaking, the outer plate 1 of the device slides back and forth on the bottom plate 12. Because of the second telescopic column 41, the center of gravity block 2 and the outer plate 1 of the device will shake, but the shaking frequency is not large, so that they shake at the same time, reducing the amplitude of the building shaking.

[0043] In the event of a high magnitude earthquake, building collapses typically begin from the top, so the top seismic layer must be stable. Similarly, when this invention is installed in the top seismic layer, upon the arrival of a seismic shear wave, the device placed in the seismic layer flips over, with the fixing plate 4 pressing against the inner wall of the top of the seismic layer, and then the top plate 15 pressing against one side of the inner wall of the seismic layer. During the lateral vibrations caused by the seismic shear wave, as the top plate 15 senses the pressure and retracts towards the center of gravity block 2 into the square groove 151 at the top of the lifting plate 3, the lifting plate 3 will slide further towards the center of gravity block 2. Simultaneously, the oblique telescopic rod 32 retracts and moves along the slide rail towards... The outer side extends until the fixing ring 33 at the bottom of the lifting plate 3 is locked onto the metal ring 11, stabilizing the building above the seismic layer. After the earthquake ends, the lifting plate 3 will slide upward again, and the top plate 15 will return to its original position to fix the seismic layer. When the seismic longitudinal wave arrives, the vertical swaying amplitude is small. At this time, the oblique telescopic rod 32 and the horizontal telescopic rod 31 begin to extend and retract with the left and right vibrations, causing the center of gravity block 2 to sway slightly up and down with the horizontal telescopic rod 31 connected to the metal ring 11. As the center of gravity block 2 is driven by the lifting plate 3 above, the oblique telescopic rod 32 contracts and extends at the same time, achieving a stabilizing effect.

[0044] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
