Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to a fireproof component for a seismic isolation bearing and its usage method. Background Technology

[0002] Seismic isolation bearings are placed in the seismic isolation layer and are mainly used to support the superstructure. They possess seismic isolation deformation capabilities, absorbing and isolating seismic waves or other external vibrations, reducing the impact of vibrations on the building, thereby improving the structure's seismic performance and safety. However, when rubber seismic isolation bearings are exposed to fire or high temperatures, the flammability and heat-induced deformation of rubber, coupled with the excellent thermal conductivity of the steel plates within the bearings, will rapidly accelerate the damage to the rubber. Therefore, when using rubber-based seismic isolation bearings, special attention must be paid to their fire-resistant design.

[0003] In the current installation process of fireproof panels for seismic isolation bearings, the fireproof panels are connected to the upper and lower supports using self-tapping screws, and the fireproof panels are connected with fireproof sealant. The fireproof sealant must be inspected and maintained regularly to ensure its normal working condition. If the fireproof sealant cracks, deteriorates, or peels off during use, it must be replaced in time. Replacing the sealant requires removing the fireproof panels to ensure complete removal and replenishment of the sealant. This requires multiple replacements during the building's service life. The relatively small floor height and clear height of the seismic isolation layer further complicate the sealant replacement process. Therefore, a better fireproof component is needed. To this end, a fireproof component for seismic isolation bearings and its usage method are proposed. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a fireproof component for seismic isolation bearings and its usage method.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fireproof component for a seismic isolation bearing, comprising fireproof cloth, a fireproof cloth winding assembly, a fireproof cloth winding and fixing assembly, and a fireproof board assembly;

[0006] The fireproof cloth is wrapped around the outside of the support. The fireproof cloth winding assembly is connected between the two ends of the fireproof cloth and pulls the two ends of the fireproof cloth tight and fixed. The fireproof cloth winding and fixing assembly is set inside the fireproof cloth winding assembly. The fireproof cloth winding and fixing assembly pushes the two ends of the fireproof cloth winding assembly in the opposite direction. Several fireproof board groups are provided, and the several groups of fireproof board groups are arranged at equal intervals on the surface of the fireproof cloth.

[0007] Preferably, the fireproof cloth winding assembly includes a fixing component body, an adjusting slide groove, and a fireproof cloth tensioning rod. The fixing component body is attached to the surface of the support block. The adjusting slide groove is opened at one end of the back of the fixing component body. The fireproof cloth tensioning rod is disposed inside the adjusting slide groove. The adjusting slide groove provides space for the fireproof cloth tensioning rod to slide laterally. One side of the fireproof cloth tensioning rod is fixedly connected to one end of the fireproof cloth.

[0008] Preferably, the fireproof cloth winding assembly further includes a fireproof cloth clearance groove and a fireproof cloth fixing rod. The fireproof cloth clearance groove is opened on both sides of the back of the fixing assembly body. A nesting groove is opened inside one side of the fireproof cloth clearance groove. The fireproof cloth fixing rod is nested in the nesting groove and is connected to the other end of the fireproof cloth.

[0009] Preferably, there is a space between the fireproof cloth fixing rod and the fireproof cloth clearance groove for the end of the fireproof cloth to pass through, and the two ends of the fireproof cloth are cross-stacked under the pull of the fireproof cloth tensioning rod and the fireproof cloth fixing rod.

[0010] Preferably, the fireproof cloth tensioning rod has a fixing component connection part in the middle, and the fixing component connection part is connected to one end of the fireproof cloth winding fixing component.

[0011] Preferably, the fireproof cloth winding and fixing assembly includes a movable rod, an elastic plate, and a screw. The movable rod is disposed inside the main body of the fixing assembly. Two sets of elastic plates are provided, with the ends of the two sets of elastic plates respectively sleeved and connected to the two ends of the movable rod. The other end of the elastic plate is sleeved and connected to the connecting part of the fixing assembly. The screw is threadedly connected to the middle of the movable rod, and the end of the screw is connected to the inner wall of the main body of the fixing assembly.

[0012] Preferably, the two sets of elastic plates are symmetrically arranged with the center line of the movable rod as the axis, and a deformation space is left between the elastic plates and the inner wall of the main body of the fixing component.

[0013] Preferably, the fireproof board assembly includes a fixing buckle, a fireproof board, and a fixing nut. Several fixing buckles are provided, arranged in two parallel rows at equal intervals on the surface of the fireproof cloth. Two vertical fixing buckles form a corresponding group. Several fireproof boards are provided, and the fireproof boards are placed between corresponding groups consisting of two fixing buckles. The fixing nut is threadedly connected to the fixing buckle.

[0014] Preferably, there is a gap between the two sets of fireproof boards for the fireproof cloth to be bent, and the bendable angle of the fireproof cloth is in the range of 0-90°.

[0015] A method for using a seismic isolation bearing fireproof component includes the following steps:

[0016] Step S1: Measure the perimeter of the support pier, cut fireproof cloth according to the measured perimeter, the length of the cut fireproof cloth is longer than the perimeter of the support pier, connect one end of the cut fireproof cloth to the fireproof cloth fixing rod by wrapping and sewing, and connect the other end of the cut fireproof cloth to the fireproof cloth tensioning rod by wrapping and sewing.

[0017] Step S2: Insert the fireproof cloth fixing rod into the nested groove inside the fireproof cloth clearance groove on one side, and pull the fireproof cloth horizontally so that the fireproof cloth passes through the fireproof cloth clearance groove on the other side.

[0018] Step S3: Temporarily place the main body of the fixing component on the surface of the support. The fireproof cloth clearance groove, together with the fireproof cloth fixing rod, presses and fixes the fireproof cloth. Pull the fireproof cloth tension rod so that the fireproof cloth tension rod drives the other end of the fireproof cloth to circle the support, thereby completely sealing the support. During the circling process, adjust the setting position of the main body of the fixing component on the surface of the support so that the setting position of the fixing buckle on the surface of the fireproof cloth is adjusted synchronously until a corresponding set of fixing buckles is assigned to each side of the corner of the support.

[0019] Step S4: Insert the other end of the fireproof cloth tensioning rod through the space left by the fireproof cloth fixing rod and the fireproof cloth clearance groove into the main body of the fixing component. The fireproof cloth tensioning rod enters into the adjusting slide groove by tilting and rotating and is restricted by the adjusting slide groove. The fireproof cloth completes the winding and stacking under the action of the fireproof cloth tensioning rod. At this time, the main body of the fixing component is fixed to the surface of the support by screws.

[0020] Step S5: Place the movable rod inside the fixed component body, connect the elastic plates at both ends of the movable rod to the connecting part of the fixed component respectively, and rotate the screw to make the screw move laterally into the fixed component body through the threaded connection with the movable rod.

[0021] Step S6: Continuously rotate the screw. Rotating the screw causes the screw to drive the movable rod to move laterally inside the main body of the fixed component through the threaded connection with the movable rod. The movable rod synchronously compresses the two sets of elastic plates. During the compression process, the other end of the elastic plate pushes the fireproof cloth tensioning rod to move laterally along the adjusting slide. During the lateral movement, the fireproof cloth tensioning rod pulls the end of the fireproof cloth.

[0022] Step S7: With one end of the fireproof cloth fixed in a position by the fireproof cloth fixing rod, a set of fireproof cloth ends move in the opposite direction to tighten. The fireproof cloth is fixed on the outside of the support. After the fireproof cloth tightening rod reaches the maximum movable position, it stops moving. The elastic plate deforms as the movable rod continues to push. The deformed elastic plate provides continuous pressure to the fireproof cloth tightening rod. The setting position of the fireproof cloth tightening rod remains fixed.

[0023] Step S8: Install fireproof boards on the fixing buckles of each corresponding group in sequence, and connect fixing nuts to the fixing buckles after the fireproof boards are installed. The fireproof boards are fixed by connecting the fixing nuts to the fixing buckles.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. This invention provides a fireproof cloth winding assembly and a fireproof cloth winding fixing assembly. The fireproof cloth winding assembly winds the fireproof cloth around the surface of the support and the outside of the shock absorber, providing fire protection for the shock absorber. The fireproof cloth winding fixing assembly fixes the fireproof cloth winding assembly, keeping the fireproof cloth in place. By using the fireproof cloth winding method to replace the original method of fixing the fireproof board with self-tapping screws, the disassembly efficiency and convenience when replacing the sealant are improved. It is also less affected by the size of the installation space and has better adaptability to different support sizes.

[0026] 2. This invention also includes a fireproof board assembly. By fixing the fireproof board assembly to the outside of the fireproof cloth, the fireproof cloth's fire resistance can be further improved, thus forming a rigid protection for the fireproof cloth. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0037] Example:

[0038] like Figure 1 - Figure 7 As shown, the present invention provides a fireproof component for a seismic isolation bearing, including a fireproof cloth 1, a fireproof cloth winding assembly 2, a fireproof cloth winding and fixing assembly 3, and a fireproof board assembly 4;

[0039] Fireproof cloth 1 is wrapped around the outside of the support. Fireproof cloth winding assembly 2 is connected between the two ends of fireproof cloth 1 and pulls the two ends of fireproof cloth 1 tight and fixed. Fireproof cloth winding fixing assembly 3 is set inside fireproof cloth winding assembly 2. Fireproof cloth winding fixing assembly 3 is set inside fireproof cloth 1 and pushes the two ends of fireproof cloth winding assembly 2 in the opposite direction. Several fireproof board groups 4 are provided. Several groups of fireproof board groups 4 are arranged at equal intervals on the surface of fireproof cloth 1.

[0040] Fireproof cloth winding assembly 2 includes a fixing assembly body 21, an adjusting slide 22, and a fireproof cloth tensioning rod 23;

[0041] The main body 21 of the fixing component is attached to the surface of the support. The adjusting groove 22 is opened at one end of the back of the main body 21 of the fixing component. The fireproof cloth tensioning rod 23 is set inside the adjusting groove 22. The adjusting groove 22 provides space for the fireproof cloth tensioning rod 23 to slide laterally. One side of the fireproof cloth tensioning rod 23 is fixedly connected to one end of the fireproof cloth 1. The fireproof cloth 1 can move a certain distance under the pull of the fireproof cloth tensioning rod 23, thereby completing the wrapping and tightening of the fireproof cloth 1.

[0042] The fireproof cloth winding assembly 2 also includes a fireproof cloth clearance groove 24 and a fireproof cloth fixing rod 25;

[0043] Fireproof cloth clearance grooves 24 are provided on both sides of the back of the fixing component body 21. One side of the fireproof cloth clearance groove 24 has a nesting groove inside, and the fireproof cloth fixing rod 25 is nested in the nesting groove. The fireproof cloth fixing rod 25 is connected to the other end of the fireproof cloth 1. There is a space between the fireproof cloth fixing rod 25 and the fireproof cloth clearance groove 24 for the end of the fireproof cloth 1 to pass through. The two ends of the fireproof cloth 1 are cross-stacked under the pull of the fireproof cloth tensioning rod 23 and the fireproof cloth fixing rod 25. When the fixing component body 21 is fixed in its setting position, the end of the fireproof cloth 1 connected to the fireproof cloth fixing rod 25 is fixed along with it. The main body 21 of the fixed component remains in a fixed position. The end of the fireproof cloth 1 connected to the fireproof cloth tensioning rod 23 can move synchronously with the fireproof cloth tensioning rod 23 as it moves laterally inside the adjusting groove 22. By overlapping the fireproof cloth 1, both ends of the fireproof cloth 1 are covered by each other, with no exposed areas, thus forming a sealed space to protect the support. At the same time, the fireproof cloth tensioning rod 23 can pull the end of the fireproof cloth 1 laterally to store the fireproof cloth 1, so that the fireproof cloth 1 can be stored by overlapping it to better adapt to the outside of supports of different specifications.

[0044] The fireproof cloth tensioning rod 23 has a fixing component connection part 231 in the middle. The fixing component connection part 231 is connected to one end of the fireproof cloth winding fixing component 3. The fireproof cloth winding fixing component 3 includes a movable rod 31, an elastic plate 32 and a screw 33.

[0045] The movable rod 31 is located inside the fixed component body 21. Two sets of elastic plates 32 are provided, with the ends of the two sets of elastic plates 32 respectively sleeved and connected to both ends of the movable rod 31. The other end of the elastic plate 32 is sleeved and connected to the fixed component connecting part 231. The screw 33 is threadedly connected to the middle of the movable rod 31, and the end of the screw 33 is connected to the inner wall of the fixed component body 21. The two sets of elastic plates 32 are symmetrically arranged about the center line of the movable rod 31. A deformation space is left between the elastic plate 32 and the inner wall of the fixed component body 21. During the process of fixing the position of the end of the fireproof cloth 1, the screw 33 is rotated. The rotation of the screw 33 causes the movable rod 31 to move horizontally inside the fixed component body 21 through the threaded connection between the screw 33 and the movable rod 31. During the movement, the movable rod 31 simultaneously compresses the two sets of elastic plates 32. During the compression, the other end of the elastic plate 32 pushes the fireproof cloth tensioning rod 23 to move laterally along the adjusting slide 22. During the lateral movement, the fireproof cloth tensioning rod 23 pulls the end of the fireproof cloth 1. With one end of the fireproof cloth 1 fixed in position by the fireproof cloth fixing rod 25, the end of one set of fireproof cloth 1 moves in the opposite direction and is tightened, so that the fireproof cloth 1 is fixed on the support. After the fireproof cloth tensioning rod 23 reaches the maximum movable position, it stops moving. The elastic plate 32 deforms as the movable rod 31 continues to push. The deformed elastic plate 32 provides continuous pressure to the fireproof cloth tensioning rod 23 to ensure that the setting position of the fireproof cloth tensioning rod 23 remains fixed.

[0046] During the rotation of the elastic plate 32, both ends of the elastic plate 32 can rotate relative to the movable rod 31 and the fixed component connection part 231 respectively, so as to adjust the connection state in a timely manner and avoid rigid deformation.

[0047] Fireproof board assembly 4 includes a fixing buckle 41, a fireproof board 42, and a fixing nut 43;

[0048] Several fixing buckles 41 are provided, arranged in two parallel rows at equal intervals on the surface of the fireproof cloth 1. Two vertical fixing buckles 41 form a corresponding group. Several groups of fireproof boards 42 are provided, and the fireproof boards 42 are placed between the corresponding groups formed by two fixing buckles 41. Fixing nuts 43 are threadedly connected to the fixing buckles 41. After the fireproof cloth 1 is installed around the support and fixed, the fireproof boards 42 are installed on each corresponding group in sequence, and fixing nuts 43 are connected to the fixing buckles 41 after the fireproof boards 42 are installed. The fireproof boards 42 are fixed by the connection between the fixing nuts 43 and the fixing buckles 41. The fireproof boards 42, which are set and fixed along the surface of the fireproof cloth 1, form a rigid protection for the support, so as to further improve the support's ability to protect against fire.

[0049] There is a gap between the two sets of fireproof boards 42 for the fireproof cloth 1 to bend. The fireproof cloth 1 can be bent at an angle of 0-90°. When the fireproof cloth 1 is installed around the support, the fireproof cloth 1 can be attached to the surface of the support and bend synchronously along the surface of the support. After bending, the two sets of fireproof boards 42 located on both sides of the corner form protection for the corner of the support.

[0050] Instructions for use of fireproof components for seismic isolation bearings:

[0051] The perimeter of the support is measured, and a fireproof cloth 1 is cut according to the measured perimeter. The length of the cut fireproof cloth 1 is longer than the perimeter of the support. One end of the cut fireproof cloth 1 is connected to the fireproof cloth fixing rod 25 by wrapping and sewing. The other end of the cut fireproof cloth 1 is connected to the fireproof cloth tensioning rod 23 by wrapping and sewing. The fireproof cloth fixing rod 25 is inserted into the nested groove opened inside the fireproof cloth clearance groove 24 on one side, and the fireproof cloth 1 is pulled laterally so that the fireproof cloth 1 passes through the fireproof cloth clearance groove 24 on the other side.

[0052] The main body 21 of the fixing component is temporarily placed on the surface of the support. The fireproof cloth clearance groove 24, together with the fireproof cloth fixing rod 25, presses and fixes the fireproof cloth 1. Pulling the fireproof cloth tensioning rod 23 causes the other end of the fireproof cloth 1 to wrap around the support, thus completely sealing the support. During the wrapping process, the setting position of the main body 21 of the fixing component on the surface of the support is adjusted so that the setting position of the fixing buckles 41 on the surface of the fireproof cloth 1 is adjusted synchronously until a corresponding set of fixing buckles 41 is assigned to each side of the corner of the support. The other end of the wrapped fireproof cloth tensioning rod 23 is then connected to the fireproof cloth through the fireproof cloth fixing rod 25. The space left by the cloth clearance groove 24 is inserted into the fixed component body 21. The fireproof cloth tensioning rod 23 enters into the adjusting slide 22 by tilting and rotating and is restricted by the adjusting slide 22. The fireproof cloth 1 completes the winding and stacking under the drive of the fireproof cloth tensioning rod 23. At this time, the fixed component body 21 is fixed to the support surface by screws. The movable rod 31 is placed inside the fixed component body 21. The elastic plates 32 at both ends of the movable rod 31 are connected to the fixed component connection part 231 respectively. The screw 33 is rotated so that the screw 33 is moved laterally and nested into the fixed component body 21 through the threaded connection with the movable rod 31.

[0053] Continuously rotating the screw 33 causes it to drive the movable rod 31 to move laterally inside the fixed assembly body 21 via a threaded connection. The movable rod 31 synchronously compresses the two sets of elastic plates 32. During the compression process, the other end of the elastic plate 32 pushes the fireproof cloth tensioning rod 23 to move laterally along the adjusting slide groove 22. During the lateral movement, the fireproof cloth tensioning rod 23 pulls the end of the fireproof cloth 1. With one end of the fireproof cloth 1 fixed in position by the fireproof cloth fixing rod 25, one set of fireproof cloth 1 ends moves in the opposite direction and tightens. 1. Fixed to the outside of the support, the fireproof bracing tension rod 23 stops moving after reaching its maximum movable position. The elastic plate 32 deforms as the movable rod 31 continues to push, and the deformed elastic plate 32 provides continuous pressure to the fireproof bracing tension rod 23. The setting position of the fireproof bracing tension rod 23 remains fixed. Fireproof plates 42 are installed on the fixing buckles 41 of each corresponding group in sequence, and fixing nuts 43 are connected to the fixing buckles 41 after the fireproof plates 42 are installed. The fixing nuts 43 and fixing buckles 41 are connected to fix the fireproof plates 42 to complete the fixing.

[0054] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
