Description

Technical Field

[0001] This invention relates to the field of earthquake-resistant equipment technology, specifically to an adaptive earthquake-resistant damper for prefabricated structures. Background Technology

[0002] With the development trend of industrialized and green construction, prefabricated structures have become the mainstream structural form in urban and rural construction due to their advantages such as factory prefabrication, rapid on-site assembly, energy saving, and environmental protection. They are widely used in residential buildings, public buildings, and industrial plants. As a core seismic energy dissipation component, the performance of dampers directly determines the seismic response control effect of the structure.

[0003] In earthquake disasters, the joints and connections of prefabricated components in prefabricated structures are prone to becoming weak points. Traditional seismic design often relies on the stiffness of the components themselves to resist seismic forces, resulting in low energy dissipation efficiency and insufficient control over structural deformation. Therefore, dampers, as key devices for passively or actively controlling seismic energy, are widely used in beam-column joints, wall panel connections, and bracing systems of prefabricated structures to reduce structural vibration response and minimize component damage by dissipating seismic energy.

[0004] Patent CN120139562A discloses a replaceable energy-dissipating metal damper for a novel multi-structured tensile metamaterial. The device includes a fixed base; the fixed base is an integral structure with a diagonal support mounting groove; a plate-shaped tensile support is mounted on the diagonal support mounting groove on the side of the fixed base; the fixed base is snapped and fixedly installed on both sides of a foam filling core; a columnar double deformation mechanism novel tensile metamaterial is sleeved and fixed to the outside of the foam filling core.

[0005] The fixing base in the above technical solution is an integrated structure. The connection interface with the prefabricated components lacks standardized design. Installation requires on-site adjustment, welding or drilling, which cannot match the factory production and rapid on-site assembly process of prefabricated components, and is difficult to adapt to the assembly errors of prefabricated structures.

[0006] As prefabricated structures expand into high-intensity seismic zones and large-span, high-rise buildings, higher demands are placed on the adaptability and ease of maintenance of dampers. Existing technologies can no longer meet the engineering requirements of rapid assembly and convenient maintenance; therefore, there is an urgent need for prefabricated structure adaptive seismic dampers to solve the aforementioned problems. Summary of the Invention

[0007] The purpose of this invention is to provide an adaptive seismic damper for prefabricated structures to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated adaptive seismic damper, comprising a damping body, wherein standardized connecting components are respectively provided at both ends of the damping body, and a control mechanism is assembled between the damping body and the connecting components;

[0030] The sensing component includes a first sensor fixedly embedded in the side wall of the cover, and the output end of the first sensor is fixedly connected to a sensing block that fits against the side of the adjustment disc.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] (1) The prefabricated structure adaptive seismic damper has the ends of the steel bars bent into a U-shape to avoid local concrete cracking and pre-embedded parts tilting caused by the single force direction of the anchors in the same direction, ensuring the integrity of the pre-embedded parts and components, providing a stable foundation for the subsequent accurate installation of the damping body, forming a root connection system between the damping body and the prefabricated components, and greatly improving the anchoring reliability.

[0033] (2) For the prefabricated structure adaptive seismic damper, the hanging plate is inserted into the second assembly slot, and then the assembly mechanism is attached to the pre-embedded mechanism. The operator does not need to hold the assembly mechanism continuously, and can immediately free his hands to carry out subsequent connection preparations, so that a single person can independently complete the process from connection to stable connection, reduce the installation labor cost, and improve the construction collaboration efficiency.

[0034] (3) The prefabricated structure adaptive seismic damper further restricts longitudinal displacement by screwing in the nut to abut the plate against the outer surface of the embedded part, forming a stable connection of the assembly mechanism. At the same time, the original outward-pulled slide is pushed inward along the guide of the slide groove and the slider, so that the plug is inserted into the second slot to lock the abutment plate and form a closed-loop interlock. This forms a cross-interlock of the structure from multiple aspects, improving the overall resistance to seismic reciprocating loads.

[0035] (4) The prefabricated structure adaptive seismic damper can absorb seismic impact energy through its own compression deformation, which greatly reduces the rigid impact between the damping body and the connecting components; at the same time, the elasticity of the foam material can assist in post-earthquake reset, avoid component deformation caused by hard collision, and extend the seismic impact resistance life of the connecting components.

[0036] (5) The prefabricated structure adaptive seismic damper has foam material and sliding plate passed through the inner end of the fastener in sequence and screwed to the embedded part, thus forming a three-dimensional stable structure of the connecting component. The newly added four corner tie increases the longitudinal pull-out force, and the force transmission path changes from local transmission to three-dimensional mesh transmission. The working load can be quickly transmitted to the connecting component through the fastener, avoiding plastic deformation caused by load accumulation in the assembly mechanism, reducing the peak concrete stress at the embedded part of the embedded part, and improving the connection stability.

[0037] (6) The prefabricated structure adaptive seismic damper has a connection design of pre-embedded mechanism, assembly mechanism and assembly mechanism, so that the connecting components do not need to be welded or drilled on site. The assembly mechanism can directly connect with the pre-embedded mechanism in the prefabricated component, which solves the pain point of inconsistent interfaces and the need for on-site adjustment, improves the compatibility with prefabricated components, shortens the installation time of a single unit, improves construction efficiency, and at the same time reduces the technical dependence on construction personnel and improves the installation qualification rate.

[0038] (7) The prefabricated structure adaptive seismic damper can adapt and adjust the position of the connector assembly in the cover by adjusting the extension and retraction of the telescopic column of the component. At the same time, the turntable is driven to rotate by starting the motor, so that the angle of the connector assembly can be adjusted by the contact between the turntable and the adjustment plate, thereby improving the scene coverage, eliminating the need to customize special connectors for different parts, reducing component inventory and design costs, and improving the flexibility and adaptability of multi-scene and multi-angle connection.

[0039] (8) The prefabricated structure adaptive seismic damper adjusts the damping gas in the pressure pipe through the pipe to solve the problems of fixed damping coefficient and poor adaptability. The adjustment of the damping gas makes the vibration acceleration decay faster during small earthquakes and the energy dissipation capacity enhanced during large earthquakes, meeting various earthquake requirements and optimizing the seismic performance under all working conditions.

[0068] The assembly plate 301 has trapezoidal slots 309 on both sides of the center.

[0069] Two sets of assembly mechanisms 4 are inserted and connected between the assembly plate 301 and the back plate 304;

[0070] Each assembly mechanism 4 includes an assembly shell 401. The assembly shell 401 has an arc pit 402 that is adapted to the nut 308 on the side near the stud 302. A sponge 403 is attached to the inner wall of the arc pit 402.

[0072] The inner end of the fastener 310 passes through the foam material 406 and the slide plate 207 in sequence and is screwed to the embedded part 201.

[0073] Please see Figure 1 , Figure 11 , Figure 12 , Figure 13 The connector assembly includes an adjustment plate 509, a second sensor 510 is fixedly embedded in the middle of the inner surface of the adjustment plate 509, a ring seat 511 is fixedly connected to the inner surface of the second sensor 510, and a connecting pipe 512 is fixedly connected to the middle of the inner surface of the second sensor 510.

[0075] The two air valves 109 are connected to the connecting pipes 512 on different sides respectively.

[0076] The control component includes a telescopic column 503 fixedly embedded in the side wall of the cover 501, an L-shaped tray 504 fixedly connected to the output end of the telescopic column 503, the tray 504 supporting the edge of the adjustment plate 509; a motor 505 fixedly embedded in the tray 504, the output end of the motor 505 extending out of the tray 504 and fixedly connected to a turntable 506 abutting against the side of the adjustment plate 509;

[0077] The sensing component includes a first sensor 507 fixedly embedded in the side wall of the cover 501, and the output end of the first sensor 507 is fixedly connected to a sensing block 508 that fits against the side of the adjustment disc 509.

[0078] The working principle of this invention is as follows:

[0079] The embedded part 201 is embedded in the inner surface of the component and is fixedly connected with steel bars 202 at equal intervals. When the component is poured with concrete, the steel bars 202 are also poured into the component. The ends of the steel bars 202 are bent into a U-shape. After the concrete is poured and solidified, the U-shaped structure forms an embedded mechanical interlock with the concrete, which can effectively resist the longitudinal tensile force generated when the damping body 1 is working. The bending directions of the ends of adjacent steel bars 202 are opposite, so that the anchoring force is evenly distributed on the inner surface of the embedded part 201. This avoids local concrete cracking and tilting of the embedded part 201 caused by the single force direction of the anchor in the same direction, ensuring the integrity of the embedded part 201 and the component. It provides a stable foundation for the subsequent accurate installation of the damping body 1, forming a root connection system between the damping body 1 and the prefabricated component, which greatly improves the reliability of the anchoring.

[0080] The connecting component includes a pre-embedded mechanism 2 embedded in the component and an assembly mechanism 3. During connection, the hanging plate 303 is aligned with the first slot 205 and inserted into the first assembly slot 203. Then, the assembly mechanism 3 is rotated 90 degrees to snap the hanging plate 303 into the second assembly slot 204. The assembly mechanism 3 is then attached to the pre-embedded mechanism 2. The operator does not need to hold the assembly mechanism 3 continuously and can immediately free their hands to carry out subsequent connection preparations. This allows a single person to independently complete the process from connection to stable connection, reducing installation labor costs and improving construction collaboration efficiency.

[0081] Inserting the abutment block 306 into the embedded part 201, the inner end of the abutment block 306 is adapted to fit into the second assembly groove 204, and the outer end of the abutment block 306 is adapted to fit into the first slot 205, thereby improving the radial pull-out resistance of the structure. The interlocking of the buckle groove 307 and the hanging plate 303 can resist the lateral shear force. Then, by screwing in the nut 308, the abutment plate 304 is abutted against the outer surface of the embedded part 201, which further restricts the longitudinal displacement and forms a stable connection of the assembly mechanism 3. At the same time, the originally pulled outward sliding plate 207 is pushed inward along the guide of the sliding groove 206 and the slider 208, so that the plug 209 is inserted into the second slot 305 to fasten the abutment plate 304 and form a closed-loop interlock. This forms a cross-interlock of the structure from multiple aspects, thereby improving the overall resistance to seismic reciprocating loads.

[0082] The assembly shell 401 is filled with foam material 406 through injection port 404. The foam material 406 further enhances the seismic performance of the connecting components. During an earthquake, the foam material 406 can absorb the seismic impact energy through its own compression deformation, which greatly reduces the rigid impact between the damping body 1 and the connecting components. At the same time, the resilience of the foam material 406 can assist in post-earthquake reset, avoid component deformation caused by hard collision, and extend the seismic impact resistance life of the connecting components.

[0083] Two sets of assembly mechanisms 4 are inserted between the assembly plate 301 and the back plate 304. The two sets of assembly mechanisms 4 are locked together by the engagement of the locking block 405 and the locking groove 309, forming a double lateral lock, which improves the lateral shear bearing capacity and can effectively resist the lateral reciprocating load during earthquakes. The symmetrical arrangement of the two sets of assembly mechanisms 4 ensures that the lateral force is evenly distributed, avoiding the failure of the engagement caused by the concentration of force. Combined with the buffering effect of the foam material 406, the lateral displacement of the connection part is controlled, improving the accuracy of displacement control.

[0084] Meanwhile, fasteners 310 are screwed to the four corners of the outer surface of the assembly plate 301. The inner end of the fastener 310 passes through the foam material 406 and the sliding plate 207 in sequence and is screwed to the embedded part 201, thereby forming a three-dimensional stable structure of the connecting component. The newly added four corner ties improve the longitudinal pull-out resistance, and the force transmission path changes from local transmission to three-dimensional mesh transmission. The working load can be quickly transmitted to the connecting component through the fasteners 310, avoiding plastic deformation of the assembly mechanism 4 due to load accumulation, reducing the peak concrete stress at the embedded part of the embedded part 201, and improving the connection stability.

[0085] The connection design of the pre-embedded mechanism 2, the assembly mechanism 3 and the assembly mechanism 4 eliminates the need for on-site welding and drilling of the connecting components. The assembly mechanism 3 can directly connect with the pre-embedded mechanism 2 pre-embedded in the prefabricated component, which solves the pain points of inconsistent interfaces and the need for on-site adjustment, improves the compatibility with prefabricated components, shortens the installation time of a single unit, improves construction efficiency, reduces the reliance on the technical skills of construction personnel, and improves the installation qualification rate.

[0086] Based on the position of the pre-embedded mechanism 2 of the connecting component embedded in the component, the position of the connector component in the cover 501 can be adapted and adjusted by controlling the extension and retraction of the telescopic column 503 of the component. At the same time, the turntable 506 is driven to rotate by starting the motor 505, so that the angle of the connector component can be adjusted by the contact between the turntable 506 and the adjustment plate 509. This improves the scene coverage, eliminates the need to customize special connectors for different parts, reduces component inventory and design costs, and enhances the flexibility and adaptability of multi-scene and multi-angle connections.

[0087] In an earthquake scenario, the sensing block 508 of the sensing component on the outside of the receiving assembly is attached to the adjustment plate 509 to sense vibration. Then, the control component is activated to adjust the receiving assembly, thereby making targeted adjustments to the damping body 1 during the actual vibration. At the same time, the second sensor 510 senses the vibration intensity, and the damping gas in the pressure pipe 103 is adjusted through the connecting pipe 512 to solve the problems of fixed damping coefficient and poor adaptability. By adjusting the damping gas, the vibration acceleration decays quickly during small earthquakes and the energy dissipation capacity is enhanced during large earthquakes, meeting various earthquake requirements and optimizing the seismic performance under all working conditions.
