A seismic bearing for building engineering

Abstract

This invention discloses a seismic bearing for building engineering in the field of seismic bearing technology, comprising a frame, a pressure rod slidably connected to the top of the frame, a support plate fixedly connected to the top of the pressure rod, a buffer spring for resetting the pressure rod inside the frame, and a buffer resetting assembly inside the frame. The buffer resetting assembly is used to absorb the potential energy of the buffer spring after the pressure rod is compressed into the frame by an external force, so that the pressure rod can be buffered during resetting. By using the buffer resetting assembly, when the support plate is subjected to pressure, the buffer spring will push the pressure rod upward again under the action of elastic potential energy. At this time, the buffer resetting assembly will limit the resetting speed of the pressure rod, so that the pressure rod rises slowly, and the elastic potential energy of the buffer spring is released slowly. The purpose of this is to absorb the elastic potential energy of the buffer spring through the buffer resetting assembly, so that the pressure rod can be buffered during resetting.

Description

Technical Field

[0001] This invention relates to the field of seismic bearing technology, specifically to a seismic bearing for building engineering. Background Technology

[0002] Seismic bearings are support devices that have a seismic resistance effect. Seismic bearings used in buildings are designed to provide a certain buffering effect when subjected to earthquakes or other vibrations.

[0003] Existing technologies disclose several invention patents in the field of building bearing technology. Among them, invention patent application number CN111926923A discloses a seismic bearing for buildings, including a support base and a damping mechanism. The support base includes an upper support and a lower support, and a support column disposed between the upper and lower supports. The damping mechanism includes an upper top block, a support block, a support platform, and a buffer structure. The upper top block is fixed to the top of the upper support. The support block is disposed between the upper top block and the support platform. A damping spring is disposed between the lower part of the support block and the support platform. The lower part of the support platform is connected to the lower support through a support rod, and damping springs are evenly disposed around the support rod between the support platform and the lower support. The buffer structure is disposed between the support platform and the lower support, which can achieve the effects of convenient installation, structural stability, and strong seismic resistance.

[0004] However, the following problems exist: While shock-absorbing springs, in conjunction with flexible rubber pads, can indeed provide some cushioning when impacted, the elastic potential energy of the shock-absorbing springs causes them to rebound after being compressed by external forces. The greater the external force, the stronger the rebound force. In other words, after the shock-absorbing springs are deformed by pressure, they will rebound the external object under the action of elastic potential energy. Furthermore, the elastic potential energy of the shock-absorbing springs will be released multiple times. This may cause secondary damage to the building when subjected to shock.

[0005] Based on this, the present invention designs a seismic bearing for building engineering to solve the problem that the seismic bearing, which uses damping springs for damping, cannot absorb the elastic potential energy of the springs, thus causing secondary damage to the building. Summary of the Invention

[0006] The purpose of this invention is to provide a seismic bearing for building engineering to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seismic bearing for building engineering, comprising a frame, a pressure rod slidably connected to the top of the frame, a support plate fixedly connected to the top of the pressure rod, a buffer spring for resetting the pressure rod inside the frame, and a buffer resetting assembly inside the frame, wherein the buffer resetting assembly is used to absorb the potential energy of the buffer spring after the pressure rod is compressed into the frame by an external force, so that the pressure rod can be buffered when resetting.

[0008] As a further embodiment of the present invention, the buffer reset assembly includes a connecting rod, one end of which is fixedly connected to the bottom of the pressure rod. A cavity is provided inside the frame, and a push plate is slidably connected inside the cavity. A slide rail is provided inside the frame, and one end of the connecting rod passes through the slide rail and is fixedly connected to the bottom of the cavity. A first fixed shaft is fixedly connected inside the top of the cavity, and a sliding cone is slidably connected to the first fixed shaft. A docking groove for engaging with the sliding cone is provided on the pressure rod. An exhaust port communicating with the cavity is provided at the top of the frame, and an air inlet window is embedded in the top of the frame. Connecting shafts are fixedly connected to the four corners at the bottom of the air inlet window. A sealing plate is slidably connected to the four connecting shafts, and a first spring for resetting the sealing plate is fixedly connected to the connecting shafts.

[0009] As a further embodiment of the present invention, a fixed seat is fixedly connected to each of the two side walls of the pressure rod, a transmission rod is rotatably connected to the fixed seat, a second fixed shaft is fixedly connected inside the frame, a sliding seat is slidably connected to the second fixed shaft, a second spring for resetting the sliding seat is sleeved on the second fixed shaft, and one end of the transmission rod is rotatably connected to the side wall of the sliding seat.

[0010] As a further embodiment of the present invention, a flange base is fixedly connected to the bottom of the frame, and the flange base has a plurality of threaded holes.

[0011] As a further embodiment of the present invention, a sealing gasket is fixed to the top of the sealing plate.

[0012] As a further embodiment of the present invention, the sliding cone block is fitted with an anti-slip pad for a high coefficient of friction.

[0013] As a further embodiment of the present invention, a silicone pad is fixedly connected to the top of the support plate.

[0014] As a further embodiment of the present invention, when the push plate slides to the bottom of the cavity, the top of the push plate is above the slide rail.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention employs a buffer reset component. When the support plate is subjected to pressure, the buffer spring, under the action of elastic potential energy, will push the pressure rod upward again. At this time, the buffer reset component will limit the reset speed of the pressure rod, so that the pressure rod rises slowly, allowing the elastic potential energy of the buffer spring to be released slowly. By absorbing the elastic potential energy of the buffer spring through the buffer reset component, the pressure rod can be buffered during reset, thereby preventing the support plate from rebounding quickly and causing secondary damage to the building, thus playing an effective shock absorption and buffering role.

[0017] 2. When the pressure rod is compressed downwards to break the buffer spring, the pressure rod will simultaneously drive the transmission rod to rotate, causing the bottom of the transmission rod to slide on the second fixed shaft, thus compressing the second spring. The transmission rods on both sides further activate the buffering effect of the pressure rod, which can effectively improve the impact resistance of the support plate. Attached Figure Description

[0026] Please see Figure 1-6The present invention provides a technical solution: a seismic support for building engineering, comprising a frame 4, a pressure rod 2 slidably connected to the top of the frame 4, a support plate 1 fixedly connected to the top of the pressure rod 2, a buffer spring 9 for resetting the pressure rod 2 is provided inside the frame 4, and a buffer resetting assembly is provided inside the frame 4. The buffer resetting assembly is used to absorb the potential energy of the buffer spring 9 after the pressure rod 2 is compressed into the frame 4 by an external force, so that the pressure rod 2 can be buffered when resetting.

[0027] When the above solution is put into practical use, such as Figure 1-2 As shown, the frame 4 is installed at the designated position, and the support plate 1 is in contact with the part that needs to be supported. When the top of the support plate 1 is impacted, the pressure will drive the pressure rod 2 to slide into the frame 4 through the support plate 1, causing the buffer spring 9 inside the frame 4 to be compressed, thereby buffering the impact pressure. When the pressure is greater than the elastic potential energy of the buffer spring 9, the buffer spring 9 cannot reset. When the pressure is less than the elastic potential energy of the buffer spring 9, the buffer spring 9 will push the pressure rod 2 upward again under the action of the elastic potential energy. At this time, the buffer reset component will limit the reset speed of the pressure rod 2, so that the pressure rod 2 rises slowly, and the elastic potential energy of the buffer spring 9 is released slowly. The purpose of this is to absorb the elastic potential energy of the buffer spring 9 through the buffer reset component, so that the pressure rod 2 can be buffered when resetting, thereby preventing the support plate 1 from rebounding quickly and causing secondary damage to the building, thus playing an effective shock absorption and buffering role.

[0028] As a further embodiment of the present invention, the buffer reset assembly includes a connecting rod 8, one end of which is fixedly connected to the bottom of the pressure rod 2. A cavity 13 is provided inside the frame 4, and a push plate 7 is slidably connected inside the cavity 13. A slide rail 14 is provided inside the frame 4. One end of the connecting rod 8 passes through the slide rail 14 and is fixedly connected to the bottom of the cavity 13. A first fixed shaft 11 is fixedly connected inside the top of the cavity 13. A sliding cone block 12 is slidably connected to the first fixed shaft 11. A docking groove 6 for docking with the sliding cone block 12 is provided on the pressure rod 2. An exhaust port 10 communicating with the cavity 13 is provided at the top of the frame 4. An air intake window 3 is embedded in the top of the frame 4. Connecting shafts 17 are fixedly connected to the four corners at the bottom of the air intake window 3. A sealing plate 15 is slidably connected to the four connecting shafts 17. A first spring 16 for resetting the sealing plate 15 is fixedly connected to the connecting shafts 17. When the push plate 7 slides to the bottom of the cavity 13, the top of the push plate 7 is above the slide rail 14.

[0029] When the above solution is put into practical use, such as Figure 2 , 3As shown in Figure 6, when the support plate 1 is subjected to external force, the pressure rod 2 compresses the buffer spring 9 and slides down. At the same time, the pressure rod 2 drives the push plate 7 to slide downward inside the cavity 13 through the connecting rod 8. The cavity 13 is sealed inside. The sliding of the push plate 7 creates a negative pressure inside the cavity 13. The pressure will attract the sealing plate 15, causing it to compress the first spring 16 and slide downward, thus opening the air intake window 3. This allows air from outside the frame 4 to enter the cavity 13 through the air intake window 3. When the buffer spring 9 releases its elastic potential energy and pushes the pressure rod 2 back to its original position, the pressure rod 2 also drives the push plate 7 to slide upward through the connecting rod 8. However, because the cavity 13 is sealed inside and the air intake window 3 restricts the sealing plate 15, air cannot be discharged from the air intake window 3. Furthermore, the slide 14 cannot connect with the cavity 13 from the top of the push plate 7, so the gas inside the cavity 13 cannot be discharged from the slide 14 either. It can only be slowly discharged through the exhaust port 10. Under pressure, the sliding cone 12 is pushed to slide along the first fixed axis 11 to the position where it connects with the docking groove 6. When the pressure rod 2 slides upward, it pushes the sliding cone 12 to slide into the cavity 13. The air pressure in the cavity 13 pushes the sliding cone 12 to squeeze the pressure rod 2. As the exhaust port 10 slowly discharges gas, the pressure inside the cavity 13 gradually decreases. Under the action of the buffer spring 9, the pressure rod 2 pushes the sliding cone 12 to slide into the cavity 13, thus achieving the effect of the pressure rod 2 slowly rising. Under the action of the buffer spring 9, as the exhaust port 10 continuously discharges gas from the cavity 13, the support plate 1 and the pressure rod 2 will eventually return to their initial positions. In this way, when the support plate 1 is subjected to pressure less than the elastic force of the buffer spring 9, causing the buffer spring 9 to contract, the buffer spring 9 will slowly drive the pressure rod 2 to return to its original position, effectively preventing the buffer spring 9 from causing secondary damage to the building under its own elastic force.

[0030] As a further embodiment of the present invention, a fixed seat 18 is fixedly connected to each of the two side walls of the pressure rod 2, and a transmission rod 19 is rotatably connected to the fixed seat 18. A second fixed shaft 21 is fixedly connected inside the frame 4, and a sliding seat 20 is slidably connected to the second fixed shaft 21. A second spring 22 for resetting the sliding seat 20 is sleeved on the second fixed shaft 21, and one end of the transmission rod 19 is rotatably connected to the side wall of the sliding seat 20.

[0031] When the above solution is put into practical use, such as Figure 4-5 As shown, when the pressure rod 2 is compressed downwards to break the buffer spring 9, the pressure rod 2 will drive the transmission rod 19 to rotate, causing the bottom of the transmission rod 19 to drive the sliding seat 20 to slide on the second fixed shaft 21, thus compressing the second spring 22. The transmission rods 19 on both sides further activate the buffering effect of the pressure rod 2, which can effectively improve the impact resistance of the support plate 1.

[0032] As a further embodiment of the present invention, a flange base plate 5 is fixedly connected to the bottom of the frame 4, and a plurality of threaded holes are provided on the flange base plate 5.

[0033] When the above solution is put into actual use, the flange base 5 makes it easier and more secure to install the frame 4.

[0034] As a further embodiment of the present invention, a sealing gasket is fixed to the top of the sealing plate 15;

[0035] When the above solution is put into actual use, the sealing plate 15 can achieve an effective sealing effect when it is fitted with the air intake window 3 by means of a sealing gasket.

[0036] As a further embodiment of the present invention, the sliding cone block 12 is externally fitted with an anti-slip pad for a high coefficient of friction;

[0037] When the above solution is put into practical use, the anti-slip pad increases the surface friction of the sliding cone 12, so that when the pressure rod 2 pushes the sliding cone 12 to slide into the cavity 13, the sliding cone 12 has a better buffering effect on the pressure rod 2, and at the same time, it can further improve the sealing effect of the sliding cone 12 on the cavity 13.

[0038] As a further embodiment of the present invention, a silicone pad is fixedly connected to the top of the support plate 1;

[0039] When the above solution is put into actual use, the silicone pad on the top of the support plate 1 can buffer the impact effect and play an effective buffering role on the surface of the support plate 1.

[0040] Working principle: The frame 4 is installed at the designated position, and the support plate 1 contacts the part that needs support. When the top of the support plate 1 is impacted, the pressure will drive the pressure rod 2 to slide into the frame 4 through the support plate 1, causing the buffer spring 9 inside the frame 4 to be compressed, thereby buffering the impact pressure. When the support plate 1 is subjected to external force, the pressure rod 2 compresses the buffer spring 9 and slides down. At the same time, the pressure rod 2 drives the push plate 7 to slide downward inside the cavity 13 through the connecting rod 8. The cavity 13 is sealed inside, and the sliding of the push plate 7 makes the cavity 13... A negative pressure is generated inside, which attracts the sealing plate 15, causing it to compress the first spring 16 and slide downwards, opening the air intake window 3. This allows air from outside the frame 4 to enter the cavity 13 through the air intake window 3. When the buffer spring 9 releases its elastic potential energy and pushes the pressure rod 2 back to its original position, the pressure rod 2 also drives the push plate 7 to slide upwards via the connecting rod 8. However, because the cavity 13 is sealed and the air intake window 3 restricts the sealing plate 15, air cannot escape from the air intake window 3, and the slide 14 cannot exit from the top of the push plate 7. The connection with cavity 13 prevents the gas inside cavity 13 from escaping through slide 14, allowing it to slowly escape through exhaust port 10. Under air pressure, sliding cone 12 is pushed along the first fixed axis 11 to the position where it aligns with docking groove 6. When pressure rod 2 slides upward, it pushes sliding cone 12 into cavity 13. The air pressure in cavity 13 pushes sliding cone 12 to compress pressure rod 2. As gas slowly escapes through exhaust port 10, the pressure inside cavity 13 gradually decreases. Pressure rod 2, under the action of buffer spring 9... The downward movement will push the sliding cone 12 to slide into the cavity 13, thereby achieving the effect of the pressure rod 2 slowly rising. Under the action of the buffer spring 9, as the gas inside the cavity 13 is continuously discharged from the exhaust port 10, the support plate 1 and the pressure rod 2 will eventually return to their initial positions. In this way, when the support plate 1 is subjected to pressure less than the elastic force of the buffer spring 9, causing the buffer spring 9 to contract, the buffer spring 9 will slowly drive the pressure rod 2 to return to its original position, effectively preventing the buffer spring 9, which has a buffering effect, from causing secondary damage to the building under its own elastic force.
