Description

Technical Field

[0001] The present invention relates to the technical field of protection devices, in particular to a fire protection device for a building seismic isolation support. Background Art

[0002] Seismic isolation technology for building structures aims to reduce the impact of earthquakes by absorbing and absorbing seismic energy, emphasizing the use of softness to overcome hardness. Laminated rubber bearing seismic isolation technology is one of these technologies, and it has the following characteristics: First, the isolation bearing has high vertical load-bearing characteristics and very small compression deformation, which can ensure the safety of the building; second, the isolation bearing also has a large horizontal deformation capacity, and the shear deformation can reach 100% without damage; third, the rubber isolation bearing has elastic reset characteristics, which can automatically restore the building to its original position after an earthquake. Seismic isolation bearings have multiple functions in the seismic isolation structure system, including vertical force transmission components and horizontal seismic isolation components, and are the most important components in seismic isolation buildings. Currently, rubber isolation bearings are the most commonly used type of isolation bearings in seismic isolation buildings. The rubber and steel plates are bonded together through a hot vulcanization process, and rubber isolation bearings have a natural fire resistance disadvantage.

[0003] Chinese Utility Model Publication No. CN216787509U, a fire protection device for building seismic isolation bearings, describes a fire protection device for seismic isolation bearings that prevents damage to the rubber gaskets inside the bearings during fires. The device utilizes water bladders placed on the upper and lower piers, with a telescopic rebound assembly positioned between them. This prevents the upper and lower piers from moving closer together during earthquakes. The telescopic rebound assembly adjusts the distance between the two bladders based on the vibrations.

[0004] However, in the existing device, a telescopic assembly is placed between the two water bags during use. Therefore, in the event of a fire, the area between the two water bags is not insulated by the water bags, and the water bags themselves do not have the same good insulation effect, which will allow heat to be transferred, resulting in poor insulation. Therefore, to address the above-mentioned issues, a seismic isolation support fire prevention device with better insulation effect has been designed. Summary of the Invention

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] See Figure 1-5A fire protection device for a seismic isolation support of a building, comprising: a lower pier 11, a seismic isolation support body 12 is arranged on the top of the lower pier 11; an upper pier 13 is arranged on the top of the seismic isolation support body 12; mounting plates 14 are symmetrically arranged on the outer side walls of the lower pier 11 and the upper pier 13; a heat insulation component 2 is symmetrically arranged on the top of the mounting plates 14, and the heat insulation component 2 includes a water tank 1 21, which is arranged on the top of the lower mounting plate 142; a water tank 2 22 is arranged at the bottom of the upper mounting plate 141, and the bottom is inserted into the interior of the water tank 1 21 and the inner The two water tanks 21 and 22 are connected to each other and contain water; a sealing strip 23 is provided on the bottom outer wall of the water tank 22 to seal the gap between the water tank 1 21 and the water tank 2 22 to prevent water from flowing out; a water storage tank 24 is provided on the top of the lower mounting plate 142 and is tightly attached to the water tank 1 21 and is connected to each other internally; a piston 25 is provided inside the water storage tank 24; a support rod 26 has its bottom inserted into the top of the water storage tank 24 and is connected to the piston 25; a weight block 27 is provided on the top of the support rod 26 to press the support rod 26 to push the piston 25 downward. The thermal insulation assembly 2 also includes a partition groove 28 provided on the bottom of the upper mounting plate 141. The thermal insulation assembly 2 also includes a telescopic plate 29 provided on the top of the weight block 27, and the top of the telescopic plate 29 is inserted into the interior of the partition groove 28.

[0034] When in use, when an earthquake occurs, the seismic isolation support body 12 will expand and contract, and the gap between the upper pier 13 and the lower pier 11 will change. When the upper pier 13 is close to the lower pier 11, water tank 2 22 will be inserted into water tank 1 21. Because water tank 2 22 and water tank 1 21 are both full of water, the internal space becomes smaller when water tank 22 is inserted into water tank 1 21, allowing water to flow into the water tank 24 through the holes at the bottom of water tank 1 21. At this time, the water rises upward inside the water tank 24, which will push the piston 25 to rise upward as well. When the upper pier 13 is away from the lower pier 11, water tank 22 is pulled out from the inside of water tank 1 21, and at the same time, the weight block 27 presses the support rod 26 to move downward, pushing the piston 25 to move inside the water tank 24 and squeeze the internal water back into the inside of water tank 1 21. When a fire occurs, water tank 1 21 and water tank 2 22 form a water wall, which makes the heat insulation effect better. At the same time, the setting of the partition groove 28 and the telescopic plate 29 can further isolate the transfer of heat and protect the seismic isolation support body 12.

[0035] Example 2

[0036] A rotating assembly is added based on the first embodiment;

[0037] participate Figure 1-5A rotating component 3 is provided inside the water tank 1 21. The rotating component 3 can stir the internal water flow to avoid sedimentation when the water tank 2 22 is inserted into the water tank 1 21. At the same time, it can clean the holes connecting the water tank 1 21 and the water storage tank 24 to prevent blockage.

[0038] Preferably, the rotating assembly 3 includes: a bracket 31 fixedly mounted on the inner side wall of the water tank 1 21, wherein the bracket 31 is hollow and does not affect the flow of water inside the water tank 1 21; a rod 32, one end of which passes through the bracket 31 and is rotatably connected to the bracket 31; a threaded groove 33 formed on the outer side wall of the rod 32; a positioning block 34, which is mounted on the inner side wall of the bottom of the water tank 2 22 and has its other end inserted into the threaded groove 33; and fan blades 35 symmetrically mounted on the outer side wall of the rod 32. The fan blades 35 are tilted downward and agitate the bottom of the water tank 1 21 when the rod 32 rotates. The rotating assembly 3 further includes a bevel gear 1 36 fixedly mounted on the bottom of the rod body 32; a worm 37 having one end extending through the connection hole between the water tank 1 21 and the water storage tank 24 and rotatably connected to the inner wall of the water storage tank 24; and a bevel gear 2 38 mounted on the other end of the worm 37 and meshing with the bevel gear 1 36. The rotating assembly 3 further includes a ball 39 mounted on one end of the positioning block 34 and sliding within the threaded groove 33.

[0039] When used for a long time, the inner walls of water tank 1 21 and water tank 2 22 may drop some impurities. To prevent these impurities from clogging the hole between water tank 1 21 and water storage tank 24, a rotating assembly is added. When the upper pier 13 approaches the lower pier 11, water tank 2 22 is inserted into the interior of water tank 1 21 and drives the positioning block 34 to slide inside the thread groove 33, which can rotate the rod 32. The setting of the ball 39 can reduce the friction between the positioning block 34 and the thread groove 33 during the sliding. When the rod 32 rotates, it drives the fan blades 35 to rotate with it, stirring the water flow inside water tank 1 21 and preventing impurities from settling. At the same time, because the fan blades 35 are tilted downward, they can stir the water flow to align with the bottom of water tank 1 21, making the stirring effect better. As the rod 32 rotates, it also drives the bevel gear 1 36 to rotate simultaneously, engaging the bevel gear 2 38, causing the worm 37 to rotate, clearing impurities in the gap between water tank 1 21 and water storage tank 24 and preventing clogging.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
