Description

Technical Field

[0001] This invention relates to the field of vibration damping and reinforcement structure technology for nodes of prefabricated buildings, specifically a vibration damping and reinforcement structure for the connection parts of nodes in prefabricated buildings. Background Technology

[0002] The vibration damping and reinforcement device at the joint of prefabricated building is a device specifically designed to enhance the seismic performance of prefabricated building structures. By optimizing the joint connection method and energy dissipation mechanism, it absorbs or dissipates seismic energy, reduces structural damage, and improves the overall seismic resistance. In order to extend the service life of each structure in the vibration damping and reinforcement device, a waterproof coating is usually sprayed on the surface of each structure to avoid corrosion.

[0003] However, this method can only prevent corrosion of the materials of each structure itself, and it is difficult to reduce the corrosion rate at the connection of each structure. This reduces the comprehensiveness of protection against water corrosion of the damping device. Moreover, the damping rods of the damping device usually need to be replaced in time to ensure the safety of the building due to various factors such as performance degradation, physical damage, exceeding the design life, and post-earthquake damage. However, the damping rods are usually connected by welding and screws. For welded damping rods, they need to be cut with a cutting device, which will increase the vibration of the building structure and increase the risk of accidents. For damping rods connected by screws, each screw needs to be removed, which significantly increases the inconvenience for maintenance personnel during disassembly and assembly.

[0004] Combining the above issues, we find that existing building joint damping devices on the market are difficult to simultaneously avoid the problems mentioned above when in use. Even if they can solve the problems, they require external tools to solve them, thus failing to achieve the desired effect. Therefore, we propose a damping and reinforcement structure for the joint connection of prefabricated buildings. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: a vibration damping and reinforcement structure for the joint connection of a prefabricated building, including a main body 1, the main body 1 including a base plate 11, a top plate 12 provided above the base plate 11, the bottom of the base plate 11 and the top of the top plate 12 are fixedly connected to the components of the prefabricated building, four damping components 13 are provided between the base plate 11 and the top plate 12, a waterproof mechanism 2 is provided on the surface of the base plate 11 and the top plate 12, and a disassembly and assembly mechanism 3 is provided on the top of the base plate 11; The waterproofing mechanism 2 is used to provide water protection for the structure between the bottom plate 11 and the top plate 12. The waterproofing mechanism 2 includes a waterproof membrane 203, which is made of EPDM rubber. The disassembly and assembly mechanism 3 includes an adjustment unit 31, which is located on the top of the base plate 11. The adjustment unit 31 is used to adjust the height of the damping component 13 during disassembly and assembly. The disassembly and assembly mechanism 3 also includes a clamping unit 32, which works in conjunction with the adjustment unit 31. The clamping unit 32 is used to laterally clamp the damping component 13, which has been adjusted to the height by the adjustment unit 31.

[0023] As a further limitation of the waterproof mechanism 2 of the present invention, the waterproof mechanism 2 also includes a first engaging groove 201 and a second engaging groove 202. The first engaging groove 201 is formed on the surface of the bottom plate 11, and the second engaging groove 202 is formed on the surface of the top plate 12. The bottom end and the top end of the waterproof membrane 203 are respectively engaged with the inner cavities of the first engaging groove 201 and the second engaging groove 202. A wear-resistant layer 204 is fixedly connected to the surface of the waterproof membrane 203. The wear-resistant layer 204 is made of fluorocarbon resin. The inner wall of the waterproof membrane 203 is fixedly connected with... An antioxidant protective layer 205 is attached, which is made of aluminum foil. Water-stop strips 206 are fixedly connected between the surface of the waterproof membrane 203 and the first locking groove 201 and the second locking groove 202, respectively. By setting up the waterproof mechanism 2, the damping component 13 can be sealed and waterproofed by the waterproof membrane 203 in conjunction with the top plate 12 and the bottom plate 11, so as to prevent external water from entering the damping component 13 and causing corrosion and loss of shock absorption effect, thereby enhancing the waterproofness of the shock absorption device and extending the service life of the shock absorption device.

[0024] The specific implementation of this embodiment is as follows: the first locking groove 201 and the second locking groove 202 are respectively opened along the perimeter of the bottom plate 11 and the top plate 12, ensuring that the waterproof membrane 203 can surround and seal the bottom plate 11 and the top plate 12. The height of the waterproof membrane 203 is slightly higher than the longitudinal stroke of the shock-absorbing device, ensuring that the waterproof membrane 203 will not be pulled and damaged by the longitudinal movement of the shock-absorbing device itself. The waterproof membrane 203 is made of EPDM rubber, which can increase the tensile strength of the waterproof membrane 203. The service life of the waterproof membrane 203 made of EPDM rubber can reach 40 to 50 years. The addition of the wear-resistant layer 204 can improve the chemical corrosion resistance and wear resistance of the waterproof membrane 203, while keeping the surface smooth and reducing dirt adhesion. The addition of the antioxidant protective layer 205 can effectively isolate oxygen and moisture, extend the antioxidant life, thereby extending the service life of the waterproof membrane 203, and ultimately achieving long-term protection for the shock-absorbing device.

[0025] Example 2: Please refer to Figures 1-10 The present invention provides a technical solution: a vibration damping and reinforcement structure for the joint connection of prefabricated buildings. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0026] As a further limitation of the disassembly and assembly mechanism 3 of the present invention, the adjustment unit 31 includes four screws 3101, all of which are fixedly connected to the top of the base plate 11, and each of the four screws 3101 corresponds to one of the four damping components 13. The surface of the screws 3101 is threadedly connected to a sleeve 3102, and the surface of each of the four sleeves 3102 is fixedly connected to a first gear 3103. The top of the base plate 11 is rotatably connected to a gear ring 3104 through a bearing, and the teeth of the four first gears 3103 mesh with the teeth of the gear ring 3104. By setting the adjustment unit 31, the sleeves 3102 can be rotated on the surface of the screws 3101 to make the sleeves 3102 vertically displaced, thereby realizing the adjustment of the vertical height of the damping components 13. The rotation of one gear ring 3104 drives the rotation of the four first gear rings 3104, thereby realizing the adjustment of the height of the four damping components 13, improving the disassembly and assembly efficiency of maintenance personnel.

[0027] The sleeve 3102 has a groove 3105 on its surface, and the bottom of the damping component 13 is fixedly connected to a locking strip 3106. The locking strip 3106 contacts the inner cavity of the groove 3105. By setting the groove 3105 and the locking strip 3106, the damping component 13 and the sleeve 3102 can be fitted together by the locking strip 3106 and the groove 3105, thereby achieving the positioning of the bottom of the damping component 13.

[0028] An extension ring 3107 is fixedly connected to the top of the toothed ring 3104. Several fitting holes 3108 are opened on the surface of the extension ring 3107. By setting the extension ring 3107 and the fitting holes 3108, a rod-shaped tool such as a screwdriver can be inserted into the fitting hole 3108 to make the extension ring 3107 rotate, thereby driving the toothed ring 3104.

[0029] The specific implementation method of this embodiment is as follows: When it is necessary to replace the damping component 13, firstly, the building structure bearing the load of the shock absorber is supported by an external jack. Then, the clamping unit 32 is used to release the clamping of the damping component 13. Then, an external rod-shaped tool is used to sequentially insert into each fitting hole 3108. The extension ring 3107 is rotated, and the rotation of the extension ring 3107 drives the toothed ring 3104 to rotate. The rotation of the toothed ring 3104 drives the four first toothed rings 3104 to enter the groove. As the screw rotates, the rotation of the first toothed ring 3104 causes the sleeve 3102 to rotate and move downward on the surface of the screw 3101. The damping assembly 13 and the sleeve 3102 are limited by the slot 3105 and the engaging strip 3106. The downward movement of the sleeve 3102 causes the damping assembly 13 to move downward until the damping assembly 13 moves to the specified height. The damping assembly 13 is moved laterally so that the engaging strip 3106 moves out of the inner cavity of the slot 3105, and the damping assembly 13 that needs to be replaced can be taken out.

[0030] Example 3: Please refer to Figures 1-10The present invention provides a technical solution: a vibration damping and reinforcement structure for the joint connection of prefabricated buildings. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0031] As a further definition of the disassembly and assembly mechanism 3 of the present invention, the clamping unit 32 includes two bow-shaped rods 3201 slidably connected to the bottom of the top plate 12. The two bow-shaped rods 3201 are arranged opposite to each other. Two sets of insert rods 3202 are fixedly connected to one side of each bow-shaped rod 3201. Each set of insert rods 3202 consists of two rods. Four positioning cylinders 3203 are rotatably connected to the bottom of the top plate 12 via bearings. The four positioning cylinders 3203 are respectively located on the top of four damping assemblies 13. A conical block 3204 is fixedly connected to the top of each damping assembly 13. The surface of the conical block 3204 contacts the inner cavity of the positioning cylinder 3203. Two through holes 3205 are opened on the surface of each positioning cylinder 3203. The surface of each set of insert rods 3202 contacts the inner cavity of each pair of through holes 3205. The top of the insertion rod 3202 contacts the bottom of the conical block 3204. Two racks 3206 are fixedly connected to opposite sides of the two bow-shaped rods 3201. A short rod 3207 is rotatably connected to the bottom of the top plate 12 via a bearing. A second gear 3208 is fixedly connected to the bottom of the short rod 3207. The teeth of the two racks 3206 mesh with the teeth of the second gear 3208. A telescopic rod 3209 is fixedly connected to the bottom of the second gear 3208. The bottom of the telescopic rod 3209 is rotatably connected to the top of the bottom plate 11 via a bearing. By setting the locking unit 32, vibration caused by cutting and replacing the damping components 13 is avoided, while simultaneously locking and unlocking the four damping components 13 is achieved, improving the speed and convenience of disassembling and assembling the damping components 13.

[0032] Three extension rods 3210 are fixedly connected to the top of each of the two bow-shaped rods 3201, and guide blocks 3211 are fixedly connected to the top of each of the three extension rods 3210. A guide groove 3212 is correspondingly provided at the bottom of the top plate 12, and the guide block 3211 is slidably connected to the inner cavity of the guide groove 3212. By setting the extension rods 3210, guide blocks 3211 and guide grooves 3212 in cooperation, the guide grooves 3212 can guide the movement trajectory of the guide blocks 3211, ensuring the stability and smoothness of the movement of the guide blocks 3211, thereby ensuring the stability of the extension rods 3210 when they move, and finally realizing the guidance of the movement of the two bow-shaped rods 3201.

[0033] A ratchet ring 3213 is fixedly connected to the top of the base plate 11. The ratchet ring 3213 is located in the inner ring of the gear ring 3104. The telescopic rod 3209 is located in the inner ring of the ratchet ring 3213. A support frame 3214 is fixedly connected to the surface of the telescopic rod 3209. A pawl 3215 is rotatably connected to the surface of the support frame 3214. The pawl 3215 meshes with the teeth of the ratchet ring 3213. A torsion spring 3216 is sleeved on the surface of the support frame 3214. One end of the torsion spring 3216 is fixedly connected to the surface of the support frame 3214, and the other end of the torsion spring 3216 is fixedly connected to the top of the pawl 3215. By setting the ratchet ring 3213, the support frame 3214, the pawl 3215, and the torsion spring 3216... In use, when the telescopic rod 3209 rotates, the outer and inner rods of the telescopic rod 3209 are engaged by a block and a slot to limit the relative rotation between them, ensuring consistency during rotation. The rotation of the telescopic rod 3209 drives the support frame 3214 and the pawl 3215 to rotate. The pawl 3215 moves within the tooth groove of the ratchet ring 3213 and generates torque on the torsion spring 3216. When the telescopic rod 3209 stops rotating, the pawl 3215 is engaged within the tooth groove of the ratchet ring 3213, thus limiting the rotation of the telescopic rod 3209. When it is necessary to remove the limitation on the rotation of the telescopic rod 3209, the pawl 3215 is moved upward away from the tooth groove cavity of the ratchet ring 3213.

[0034] The damping assembly 13 includes a damping rod 1301, the top of which is fixedly connected to the bottom of the conical block 3204. Two limiting plates 1302 are fixedly sleeved on the surface of the damping rod 1301, and a spring 1303 is slidably sleeved on the surface of the damping rod 1301. The two ends of the spring 1303 are fixedly connected to the opposite sides of the two limiting plates 1302 respectively. The bottom of the lower limiting plate 1302 contacts the top of the locking block, and the upper limiting plate 1302 contacts the bottom of the positioning cylinder 3203. By setting the damping rod 1301, the limiting plates 1302 and the spring 1303 to work together, a complete damping system can be formed to achieve vibration reduction at the joint of the prefabricated building.

[0035] Several locking rods 3217 are fixedly connected to the top of the upper limiting plate 1302, and a limiting groove 3218 is correspondingly opened at the bottom of the positioning cylinder 3203. The surface of the locking rod 3217 contacts the inner cavity of the limiting groove 3218. By setting the locking rod 3217 and the limiting groove 3218 to work together, the damping component 13 and the positioning cylinder 3203 can be rotated in a consistent manner, thereby ensuring smooth disassembly and assembly. Furthermore, the engagement of the locking rod 3217 and the limiting groove 3218 can increase the limiting force of the damping component 13 in the horizontal direction, ensuring the firmness of the damping component 13 during use.

[0036] The specific implementation of this embodiment is as follows: When it is necessary to clamp the damping component 13, the telescopic rod 3209 is rotated. The telescopic rod 3209 rotates at the bottom of the top plate 12 via the short rod 3207 and the second gear 3208. The rotation of the second gear 3208 causes the two racks 3206 to move away from each other. The movement of the two racks 3206 causes the two bow-shaped rods 3201 to move. The movement of the bow-shaped rods 3201 causes the insertion rod 3202 to move into the insertion hole 3205 on the surface of the positioning cylinder 3203 until the insertion rod 3202 is embedded in the insertion hole 3205 and one end of the insertion rod 3202 contacts the inner wall of the positioning cylinder 3203. The damping component 13 has been adjusted to a suitable height by the adjustment unit 31, and the insertion hole 3205 has also been adjusted. In the correct position, the top of the conical block 3204 contacts the inner top of the positioning cylinder 3203, the locking rod 3217 engages with the corresponding limiting groove 3218, and when the insert rod 3202 is inserted into the insertion hole 3205, the insert rod 3202 simultaneously contacts the bottom of the conical block 3204, supporting the conical block 3204 and thus achieving vertical support for the damping assembly 13. At the same time, the engagement of the insert rod 3202 with the insertion hole 3205 limits the rotation angle of the positioning cylinder 3203, increasing the stability of the damping assembly 13 during use. Furthermore, the extension rod 3209 increases the connection between the top plate 12 and the bottom plate 11, and the extension and retraction of the extension rod 3209 can flexibly match the extension and retraction movement of the damping assembly 13 during operation.
