Description

Technical Field

[0001] The present invention belongs to the technical field of seismic isolation bearing structures, and in particular relates to a tensile friction damping seismic isolation rubber bearing and an integrated vulcanization production method. Background Art

[0002] Seismic isolation bearings are supporting devices installed in structures to meet seismic isolation requirements. They add an isolation layer between the superstructure and the foundation, installing rubber isolation bearings to create a soft connection with the ground. This technology can offset approximately 80% of the energy of an earthquake. For example, laminated rubber bearings (also known as seismic isolation rubber bearings, sandwich rubber pads, etc.) are structural components with low horizontal stiffness and high vertical stiffness. They can withstand large horizontal deformations and can serve as part of a load-bearing system. This seismic resistance technology originated from the development of rocket engines.

[0003] At present, a Chinese patent with publication number CN217974876 and publication date December 6, 2022 discloses a seismic isolation bearing with a protective structure, including a lower connecting steel plate and an upper connecting steel plate, an upper connecting steel plate is provided on the outside of the lower connecting steel plate, an upper sealing plate is provided at the center position of the bottom end of the upper connecting steel plate, a lower sealing plate is provided at the center position of the top end of the lower connecting steel plate, a lead core is provided at the center position of the top end of the lower sealing plate, and the top end of the lead core extends to the interior of the upper sealing plate, a lower annular groove block is provided at the top end of the lower connecting steel plate on one side of the lower sealing plate, an upper annular groove block is provided at the bottom end of the upper connecting steel plate above the lower annular groove block, an annular protective plate is provided inside the upper annular groove block, an annular telescopic protective plate is provided at the bottom end of the annular protective plate, and the top end of the annular telescopic protective plate extends to the interior of the annular protective plate, and the bottom end of the annular telescopic protective plate extends to the interior of the lower annular groove block.

[0004] A lead core is provided at the center of the top of the lower sealing plate. However, lead is a toxic substance that harms the human body and pollutes the environment. Currently, some countries and regions have issued clear restrictions on the use of lead. At the same time, lead is prone to fatigue shear failure under low-cycle loads. The lead-core seismic isolation rubber bearing generates a lot of heat during large-displacement horizontal shearing, which squeezes the rubber during the shearing process, causing damage to the rubber layer, shear failure of the lead core, increased residual deformation of the bearing, and impaired ultimate performance. Summary of the Invention

[0005] The purpose of the present invention is to provide a tensile friction damping seismic isolation rubber bearing that can conveniently replace the lead core to provide damping.

[0006] The above technical object of the present invention is achieved through the following technical solutions: A tensile friction damping isolation rubber bearing, comprising an upper connecting plate, a lower connecting plate, a rubber bearing body located between the upper connecting plate and the lower connecting plate, mounting holes opened at the four corners of the upper connecting plate and the lower connecting plate, and mounting bolts passing through the mounting holes. The rubber bearing body includes multiple steel plates, multiple rubber sheets respectively embedded between the upper and lower adjacent steel plates, and a rubber protective layer located outside the multiple steel plates and the multiple rubber sheets. A first through hole extending in the vertical direction is opened between the multiple steel plates and the multiple rubber sheets, and multiple friction plates stacked together in the vertical direction are arranged in the first through hole. A disc spring is arranged at the upper ends of the multiple friction plates.

[0007] By adopting the above technical solutions, the friction force generated by the friction plates when the rubber bearing body undergoes shear deformation is used to provide the yield force and damping for the rubber bearing body, which can directly replace the lead core isolation rubber bearing and the high damping rubber bearing; at the same time, it also avoids the lead harming the human body and polluting the environment after adopting the lead core isolation rubber bearing.

[0008] The further setting of the present invention is: A tensile anti-overturning component is further arranged between the upper connecting plate and the lower connecting plate. The tensile anti-overturning component includes a second through hole opened at the center of the multiple friction plates, a pressing plate arranged on the upper connecting plate and located at the position of the friction plates, a threaded hole opened at the center of the pressing plate, a tensile bolt threadedly connected in the threaded hole, and a tensile rope with one end fixed to the lower connecting plate and the other end fixed to the tensile bolt.

[0009] By adopting the above technical solutions, a tensile anti-overturning component is additionally provided while providing damping. When a large shear deformation generates an overturning force, the tensile rope can provide a tensile effect, broadening the application range of the bearing, and enabling it to play a role in tensile anti-overturning when used under high-rise buildings or buildings with a cantilever structure.

[0010] The further setting of the present invention is: A fireproof cloth sleeve is wrapped outside the rubber protective layer.

[0011] By adopting the above technical solutions, the fireproof cloth sleeve can play a fireproof effect, thereby providing fire protection for the rubber protective layer.

[0012] The further setting of the present invention is: It further includes two "U-shaped" support wooden boards for temporarily protecting the periphery of the rubber bearing body during construction operations. The fireproof cloth sleeve includes two semi-circular cloth belts respectively corresponding to the two support wooden boards, and a limiting component for limiting the support wooden boards on the peripheries of the upper connecting plate and the lower connecting plate is arranged between the cloth belt and the support wooden board.

[0013] By adopting the above technical solution, when the rubber bearing body has just been constructed, the area outside the rubber bearing body is often still under construction. At this time, the limiting component is used to connect the cloth belt and the supporting wooden board, so that the two supporting wooden boards are spliced and wrapped around the circumference of the rubber bearing body. Finally, the supporting wooden board can be used to temporarily protect the circumference of the rubber bearing body, thereby reducing the possibility of damage to the rubber bearing body after being knocked during the building operation.

[0014] The further setting of the present invention is that: the limiting component includes connecting springs arranged on the upper and lower sides of the end of the cloth belt, connecting sleeves arranged at the ends of the connecting springs away from the cloth belt, adjusting bolts whose one end is circumferentially rotatably connected and axially fixedly connected in the connecting sleeves, internal thread sleeves threadedly connected to the adjusting bolts, and pressing plates arranged on the side walls of the internal thread sleeves and used for pressing against the outer wall of the supporting wooden board.

[0015] By adopting the above technical solution, one end of the connecting spring is connected to the side position of the end of the cloth belt and the other end is connected to the adjusting bolt. By rotating the adjusting bolt, the pressing plate can be made to press against the outer wall of the supporting wooden board. Subsequently, the supporting wooden board can press against the circumferences of the upper connecting plate and the lower connecting plate, and the two supporting wooden boards can be spliced to form a wrapped protection around the circumference of the rubber bearing body.

[0016] The further setting of the present invention is that: the connecting sleeve is provided with a "冂"-shaped movable arm for connecting the end of the connecting spring away from the cloth belt, movable columns are arranged at both ends of the movable arm, connecting holes for the movable columns to be embedded are opened on both sides of the connecting sleeve, and annular grooves for the ends of the movable columns to be embedded are opened on the circumferences of the ends of the adjusting bolts.

[0017] By adopting the above technical solution, the movable arm relies on the movable column passing through the connecting hole and being embedded in the annular groove. At this time, the movable arm can swing around the central axis of the connecting hole; at the same time, the movable column can position the axial movement of the adjusting bolt, and the movable column can also move circumferentially along the annular groove, so that the adjusting bolt is circumferentially rotatably connected and axially fixedly connected in the connecting sleeve. At this time, it can be ensured that the connecting spring is not rotated when the adjusting bolt is rotated.

[0018] The further setting of the present invention is that: the pressing plate is provided with a wrapping groove for the head end of the mounting bolt at the corner of the upper connecting plate or the lower connecting plate to be embedded.

[0019] By adopting the above technical solution, when the building operation around the circumference of the rubber bearing body is completed, the supporting wooden board needs to be removed. After loosening the adjusting bolt, the pressing plate can be detached from the supporting wooden board, and at this time, the supporting wooden board can be disassembled;

[0020] The wrapping groove opened on the clamping plate is used to move the clamping plate to the corner of the upper connecting plate or the lower connecting plate, and then the head end of the mounting bolt can be embedded in the wrapping groove, so that the head end of the mounting bolt is wrapped and protected by the clamping plate, thereby delaying the aging process of the mounting bolt.

[0021] The present invention is further configured such that the length of the cloth belt is greater than half the cross-sectional circumference of the rubber protective layer, and when the head end of the mounting bolt is embedded in the wrapping groove, the adjusting bolt is rotated so that the connecting sleeve is pressed tightly against the outer wall of the rubber protective layer.

[0022] By adopting the above technical solution, firstly, the length of the cloth belt is greater than half of the circumference of the cross section of the rubber protective layer, so that the ends of the two cloth belts can be overlapped together, thereby facilitating the two cloth belts to completely wrap the circumference of the rubber protective layer, wherein the connecting spring on the inner cloth belt is inserted from the side of the cloth belt;

[0023] After the head end of the mounting bolt is inserted into the wrapping groove, the adjusting bolt can be rotated so that the connecting sleeve is pressed against the outer wall of the rubber protective layer. At this time, the connecting spring can be tightly fitted to the peripheral side of the rubber protective layer, which is conducive to the close fit of the end of the cloth belt against the outer wall of the rubber protective layer and prevents the end of the cloth belt from warping on the rubber protective layer.

[0024] At the same time, after the connecting sleeve is pressed against the rubber protective layer, the reaction force generated can make the head end of the mounting bolt press against the inner wall of the wrapping groove, which is conducive to the stable wrapping connection between the clamping plate and the mounting bolt.

[0025] The purpose of the present invention is to provide an integrated vulcanization production method for a tensile friction damping seismic isolation rubber bearing, which can facilitate the processing of the seismic isolation rubber bearing.

[0026] The above technical objectives of the present invention are achieved through the following technical solutions: a method for producing an integrated vulcanization of a tensile friction damping and seismic isolation rubber bearing, including the following steps:

[0027] S1. Place the lower connecting plate in the mold, and set a tension rope connection point inside the lower connecting plate;

[0028] S2. Stack the friction plate and the disc spring on the lower connecting plate in sequence, so that the friction plate and the disc spring are compressed and fitted to form an integral friction damping component;

[0029] S3. By using a sufficiently large preload force to constrain the friction damping component, all parts are compressed and fitted together;

[0030] S4. Stack the rubber sheet and steel plate in the mold, then buckle the connecting plate and use external positioning pins to position and close the mold, and place it in a flat vulcanizer or other vulcanizing device to complete vulcanization. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0041] A tensile friction damping isolation rubber bearing, referring to Figure 1 、 Figure 2 、 Figure 3 , this tensile friction damping isolation rubber bearing includes an upper connecting plate 1, a lower connecting plate 2, a rubber bearing body 3, mounting holes 4, mounting bolts 41, and supporting wooden boards 8. Among them, the rubber bearing body 3 is located between the upper connecting plate 1 and the lower connecting plate 2, and the mounting holes 4 are opened at the four corners of the upper connecting plate 1 and the lower connecting plate 2, and two mounting holes 4 are opened at each corner. At the same time, the mounting bolts 41 are used to connect the building after passing through the mounting holes 4; and there are two supporting wooden boards 8 arranged in a "U" shape, and the two supporting wooden boards 8 are used to temporarily protect the periphery of the rubber bearing body 3 during construction operations.

[0042] Referring to Figure 1 、 Figure 2 , the rubber bearing body 3 includes multiple steel plates 31, multiple rubber sheets 32 respectively embedded between the upper and lower adjacent steel plates 31, and a rubber protection layer 33 located outside the multiple steel plates 31 and the multiple rubber sheets 32. Among them, a first through hole 5 extending in the vertical direction is opened between the multiple steel plates 31 and the multiple rubber sheets 32, and a friction plate 51 is arranged in the first through hole 5. At the same time, multiple friction plates 51 are stacked together in the vertical direction, and two disc springs 52 are arranged at the upper ends of the multiple friction plates 51, and the two disc springs 52 are also stacked together in the vertical direction.

[0043] Referring to Figure 1 、 Figure 2 , a tensile anti-overturning component 6 is further arranged between the upper connecting plate 1 and the lower connecting plate 2. This tensile anti-overturning component 6 includes a second through hole 61, a pressing plate 62, a threaded hole 63, a tensile bolt 64, and a tensile rope 65. Among them, the second through hole 61 is opened at the center of the multiple friction plates 51, and the pressing plate 62 is connected to the upper connecting plate 1 by bolts and is located at the position of the friction plate 51. At the same time, the threaded hole 63 is opened at the center of the pressing plate 62, and a counterbore is opened at the upper end of the threaded hole 63. Among them, the tensile bolt 64 is threadedly connected in the threaded hole 63, and one end of the tensile rope 65 is fixed to the lower connecting plate 2 and the other end is fixed to the tensile bolt 64. The end of the tensile rope 65 is connected and fixed to the lower connecting plate 2 and the tensile bolt 64 by means of a hanging ring or an opening.

[0044] Referring to Figure 3 、 Figure 4 、 Figure 5 , Figure 6 , a fireproof cloth sleeve 7 is further wrapped outside the rubber protection layer 33. The fireproof cloth sleeve 7 is a silicone rubber coated fiberglass cloth. The fireproof cloth sleeve 7 includes two semicircular cloth belts 71 corresponding to the two support wooden boards 8 respectively, and the length of the cloth belt 71 is greater than half of the cross-sectional perimeter of the rubber protection layer 33. At the same time, a limiting component 9 is also arranged between the cloth belt 71 and the support wooden board 8. The limiting component 9 is used to limit the support wooden board 8 on the circumferences of the upper connecting plate 1 and the lower connecting plate 2. The limiting component 9 includes a connecting spring 91, a connecting sleeve 92, an adjusting bolt 93, an internal thread sleeve 94, and a pressing plate 95. The connecting spring 91 is arranged on the upper and lower sides of the end of the cloth belt 71. At this time, there are corresponding connecting springs 91 at the four corners of each cloth belt 71. The connecting sleeve 92 is arranged at the end of the connecting spring 91 away from the cloth belt 71. At the same time, the connecting sleeve 92 is provided with a "冂"-shaped movable arm 921 for welding the end of the connecting spring 91 away from the cloth belt 71, and movable columns 922 are integrally arranged at both ends of the movable arm 921. Connecting holes 923 for the movable columns 922 to be embedded are opened on both sides of the connecting sleeve 92.

[0045] Refer to Figure 4 , Figure 6 , Figure 7 , the adjusting bolt 93 is connected to the inside of the connecting sleeve 92 at one end. A ring groove 931 for the end of the movable column 922 to be embedded is opened on the circumferential side of the end of the adjusting bolt 93. At this time, the end of the adjusting bolt 93 can be circumferentially rotatably connected and axially fixedly connected to the inside of the connecting sleeve 92. At the same time, the internal thread sleeve 9 is threadedly connected to the adjusting bolt 93, and the pressing plate 95 is welded to the side wall of the internal thread sleeve 94. The pressing plate 95 can be used to press against the outer wall of the support wooden board 8. A wrapping groove 951 is further opened on the side of the pressing plate 95 away from the internal thread sleeve 94. The wrapping groove 951 can be used for the head end of the mounting bolt 41 at the corner of the upper connecting plate 1 or the lower connecting plate 2 to be embedded. At the same time, when the head end of the mounting bolt 41 is embedded in the wrapping groove 951, the connecting sleeve 92 is made to abut against the outer wall of the rubber protection layer 33 after the adjusting bolt 93 rotates.

[0046] Principle: When the rubber bearing body 3 has just been constructed, the areas outside the rubber bearing body 3 are often still in the construction state. At this time, one end of the connecting spring 91 is connected to the side position of the end of the cloth belt 71 and the other end is connected to the adjusting bolt 93. The adjusting bolt 93 is rotated, so that the pressing plate 95 abuts against the outer wall of the support wooden board 8. Subsequently, the support wooden board 8 can abut against the circumferences of the upper connecting plate 1 and the lower connecting plate 2. The two support wooden boards 8 can be spliced to form a wrap-around protection for the circumferential side of the rubber bearing body 3. Finally, the circumferential side of the rubber bearing body 3 can be temporarily protected by the support wooden board 8, thereby reducing the possibility of the rubber bearing body 3 being damaged after being knocked during the building operation.

[0047] When the construction work on the side of the rubber bearing body 3 is completed, the supporting wooden board 8 needs to be removed. By loosening the adjusting bolt 93, the clamping plate 95 can be detached from the supporting wooden board 8, and the supporting wooden board 8 can be removed at this time.

[0048] Then, the clamping plate 95 can be moved to the corner of the upper connecting plate 1 or the lower connecting plate 2 by using the wrapping groove 951 opened on the clamping plate 95, and then the head end of the mounting bolt 41 can be embedded in the wrapping groove 951, so that the head end of the mounting bolt 41 is wrapped and protected by the clamping plate 95, and the aging process of the mounting bolt 41 is delayed; wherein, after the head end of the mounting bolt 41 is embedded in the wrapping groove 951, the adjusting bolt 93 can be rotated so that the connecting sleeve 92 is pressed against the outer wall of the rubber protective layer 33, and the connecting spring 91 can be tightly fitted on the peripheral side of the rubber protective layer 33, which is conducive to the end of the cloth belt 71 being tightly fitted on the outer wall of the rubber protective layer 33, thereby preventing the end of the cloth belt 71 from warping on the rubber protective layer 33.

[0049] At the same time, after the connecting sleeve 92 is pressed against the rubber protective layer 33, the reaction force generated can make the head end of the mounting bolt 41 press against the inner wall of the wrapping groove 951, which is conducive to the stable wrapping connection between the clamping plate 95 and the mounting bolt 41.

[0050] At this time, after removing the supporting wooden board 8 , two cloth belts 71 can be used to form a fireproof cloth cover 7 to wrap around the outside of the rubber protective layer 33 , thereby providing fire protection for the rubber protective layer 33 .

[0051] An integrated vulcanization production method for a tensile friction damping and seismic isolation rubber bearing includes the following steps:

[0052] S1. Place the lower connecting plate in the mold, and set a tension rope connection point inside the lower connecting plate;

[0053] S2. Stack the friction plate and the disc spring on the lower connecting plate in sequence, so that the friction plate and the disc spring are compressed and fitted to form an integral friction damping component;

[0054] S3. By using a sufficiently large preload force to constrain the friction damping component, all parts are compressed and fitted together;

[0055] S4. Stack the rubber sheet and steel plate in the mold, then buckle the connecting plate and use external positioning pins to position and close the mold, and place it in a flat vulcanizer or other vulcanizing device to complete vulcanization.

[0056] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
