Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a wall-type damper and its installation method. Background Technology

[0002] A damper is a device that provides resistance to motion and reduces the energy of motion. Various types of dampers (or shock absorbers) have long been used in industries such as aerospace, aviation, military, guns, and automobiles to reduce vibration and dissipate energy. Traditional dampers rely on the elastic force of springs to slow down vibration and dissipate energy, or on the vibration of the rigid structure itself. It is difficult to flexibly adjust their stiffness and damping characteristics, and they cannot well match the needs of different structures under different working conditions. Moreover, under long-term use or extreme loads, local stress concentration is prone to occur, leading to premature damage of the damper and affecting its service life and performance stability. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wall-type damper and its installation method. It can not only reduce vibration and dissipate energy by using energy dissipation boxes individually, but also dissipate energy by using connecting components to connect two energy dissipation boxes, thereby improving the damping effect.

[0004] To achieve the above objectives, the present invention adopts a wall-type damper, comprising two energy dissipation boxes and a connector detachably connected between the two energy dissipation boxes. Each energy dissipation box has a cavity, and at least one partition is connected within the cavity to divide it into at least two independent spaces. Each independent space is filled with a viscoelastic material for vibration damping and energy dissipation. One end of each energy dissipation box is connected to a connecting lug for connection to an existing structure, and the other end of each energy dissipation box is fixed with a slot. The two ends of the connector are detachably and movably inserted into the slots of the two energy dissipation boxes, and the ends of the connector and the corresponding slots are configured such that when the ends of the connector are inserted into the corresponding slots, they can move relative to each other within a certain range.

[0005] A further improvement of the wall-type damper of the present invention is that a limiting block that can elastically extend and retract along a direction perpendicular to the insertion direction is connected to the side of the end of the connector, and a limiting hole is provided on the side wall of the slot for the corresponding limiting block to be engaged; when the end of the connector is inserted into the corresponding slot and the limiting block is facing the limiting hole, the limiting block automatically engages in the limiting hole under elastic action, and there is a margin between the end of the connector and the bottom of the slot to satisfy the relative movement within a certain range. The side of the limiting block facing the bottom of the slot is formed as a slope to allow the end of the connector to move relatively within the certain range, and the side of the limiting block facing away from the bottom of the slot is formed as a straight surface to prevent the end of the connector from moving relatively outside the certain range.

[0006] A further improvement of the wall damper of the present invention is that an installation groove is provided on the side of the end of the connector, and the limiting block is elastically and telescopically connected to the installation groove through an elastic member. The elastic member has a reset state and a compression state, and the compression state is satisfied to allow the limiting block to retract into the installation groove. The reset state is satisfied to allow the limiting block to extend out of the installation groove and be engaged in the limiting hole when the end of the limiting block is inserted into the slot and the limiting block is aligned with the limiting hole.

[0007] A further improvement of the wall-type damper of the present invention is that the elastic element is a spring, located in the mounting groove, and the two ends of the spring are respectively connected to the limiting block and the bottom of the mounting groove.

[0008] A further improvement of the wall damper of the present invention is that the connecting component is a strip plate, the two ends of the strip plate are respectively used to be inserted into the slots of the two energy dissipation boxes, the two opposite sides of each end of the strip plate are connected to the limiting block, and the two opposite sides of each slot are provided with limiting holes for the corresponding two limiting blocks to be engaged.

[0009] A further improvement of the wall damper of the present invention is that sliders are connected to both sides of the limiting block, and limiting grooves extending along the depth direction of the mounting groove are provided on the inner walls of both sides of the mounting groove to allow the corresponding sliders to slide.

[0010] A method for installing a wall-mounted damper includes the following steps: Step 1: Provide the above-mentioned wall-mounted damper; Step 2: Insert both ends of the connector into the slots of the two energy dissipation boxes respectively; Step 3: Connect the connecting lugs of the two energy dissipation boxes to the corresponding existing structures respectively.

[0011] A further improvement of the installation method of the wall damper of the present invention is that a limiting block that can elastically extend and retract along a direction perpendicular to the insertion direction is connected to the side of the end of the connector, and a limiting hole is provided on the side wall of the slot for the corresponding limiting block to be inserted. The side of the limiting block facing the bottom of the slot is formed as a slope, and the side of the limiting block facing away from the bottom of the slot is formed as a straight surface. When performing step 2 above, the end of the connector is inserted into the corresponding slot, so that the end of the slot presses against the slope and causes the limiting block to retract inward. When the limiting block is facing the limiting hole, the limiting block resets and is locked into the limiting hole.

[0012] Compared with the prior art, the advantages of the present invention are: The two energy dissipation boxes are reliably and flexibly connected by a connecting component, enabling them to move smoothly and collaboratively when facing structural vibrations, and to work effectively together under different working conditions to meet the needs of complex environments.

[0020] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The wall-type damper and its installation method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1-5 As shown, the wall damper includes two energy dissipation boxes 1 and a connector detachably connected between the two energy dissipation boxes 1. Each energy dissipation box 1 has a cavity, and at least one partition 7 is connected inside the cavity to divide the cavity into at least two independent spaces. Each independent space is filled with viscoelastic material 8 for vibration damping and energy dissipation. One end of each energy dissipation box 1 is connected to a connecting lug 3 for connecting to an existing structure, and the other end of each energy dissipation box 1 is fixed with a slot 5. The two ends of the connector are detachably and movably inserted into the slots 5 of the two energy dissipation boxes 1, and the ends of the connector and the corresponding slots 5 are configured such that when the ends of the connector are inserted into the corresponding slots 5, they can move relative to each other within a certain range.

[0023] The two energy dissipation boxes 1 are reliably and flexibly connected by the connecting components, so that the two energy dissipation boxes 1 can move smoothly and coordinately when facing structural vibrations, and work together effectively under different working conditions to meet the needs of complex environments.

[0024] When the energy dissipation box 1 is subjected to vibration transmission from the existing structure, the energy dissipation box 1 and the internal partition 7 will also vibrate, thereby causing the viscoelastic material 8 in each independent space to vibrate and dissipate energy.

[0025] Specifically, the viscoelastic material 8 is a viscoelastic rubber.

[0026] Preferably, the side of the end of the connector is connected to a limiting block 4 that can elastically extend and retract along a direction perpendicular to the insertion direction. The side wall of the slot 5 is provided with a limiting hole 6 for the limiting block 4 to be engaged. When the end of the connector is inserted into the slot 5 and the limiting block 4 is aligned with the limiting hole 6, the limiting block 4 automatically engages with the limiting hole 6 under elastic action. A certain amount of space is left between the end of the connector and the bottom of the slot 5 to allow relative movement within a certain range. The side of the limiting block 4 facing the bottom of the slot 5 is formed as a slope 11 to allow the end of the connector to move relatively within a certain range. The side of the limiting block 4 facing away from the bottom of the slot 5 is formed as a straight surface to prevent the end of the connector from moving relatively outside the certain range.

[0027] When the two energy dissipation boxes 1 are inserted into the connector, when relative inward stress is generated between the two energy dissipation boxes 1, the position can be adjusted adaptively. The limiting hole 6 of the slot 5 will squeeze the slope 11, forcing the limiting block 4 to be pressed into the limiting hole 6. Then the end of the connector can move further towards the bottom of the slot 5, realizing relative sliding between the energy dissipation box 1 and the connector, avoiding stress concentration damage to the structure, and avoiding rigid impact between the two energy dissipation boxes 1.

[0028] By setting the slope 11 and the straight surface, the connector can slide relative to the slot 5 while preventing the connector from detaching from the slot 5.

[0029] Preferably, the side of the end of the connector is provided with a mounting groove 9, and the limiting block 4 is elastically and telescopically connected to the mounting groove 9 by an elastic member. The elastic member has a reset state and a compressed state. The compressed state is sufficient to allow the limiting block 4 to retract into the mounting groove 9, and the reset state is sufficient to allow the limiting block 4 to extend out of the mounting groove 9 and be engaged in the limiting hole 6 when the end of the limiting block 4 is inserted into the slot 5 and the limiting block 4 is aligned with the limiting hole 6.

[0030] When the limiting hole 6 of the slot 5 presses against the slope 11, the limiting block 4 will compress the elastic element and be forced to move into the mounting groove 9 until the limiting block 4 is fully compressed into the mounting groove 9, at which point the connector will slide relative to the slot 5.

[0031] By setting a limiting block 4 and cooperating with the elastic element, the energy dissipation box 1 and the strip plate 2 can be detachably connected.

[0032] Specifically, the depth of the mounting groove 9 is adapted to the height of the limiting block 4.

[0033] Preferably, the elastic element is a spring 10, located in the mounting groove 9, with both ends of the spring 10 connected to the limiting block 4 and the bottom of the mounting groove 9, respectively.

[0034] The reciprocating extension and retraction of the spring 10 can also absorb and dissipate some energy, further dissipating energy and improving the damping effect.

[0035] Preferably, the connecting component is a strip-shaped insert plate 2, the two ends of which are respectively used to be inserted into the slots 5 of the two energy dissipation boxes 1. Each end of the strip-shaped insert plate 2 has a limiting block 4 connected to its opposite sides. Each slot 5 has a limiting hole 6 on its opposite sides for the corresponding two limiting blocks 4 to be inserted into.

[0036] By setting four limiting blocks 4 on the strip plate 2, the connection stability between the strip plate 2 and the two energy dissipation boxes 1 is ensured.

[0037] Preferably, sliders are connected to both sides of the limiting block 4, and limiting grooves extending along the depth direction of the mounting groove 9 are provided on the inner walls of both sides of the mounting groove 9 to allow the sliders to slide.

[0038] By setting the slider and the limiting groove, the sliding stability of the limiting block 4 is ensured.

[0039] Specifically, a friction plate is connected inside the limiting groove, and the slider slides in cooperation with the friction plate.

[0040] By setting this friction plate, the friction between the slider and the friction plate is increased, providing additional resistance to the sliding of the limit block 4 to further dissipate energy and improve the damping effect.

[0041] A method for installing a wall-mounted damper includes the following steps: Step 1: Provide the above-mentioned wall-mounted damper; Step 2: Insert both ends of the connector into the slots 5 of the two energy dissipation boxes 1 respectively; Step 3: Connect the two connecting ears 3 of the energy dissipation box 1 to the corresponding existing structures respectively.

[0042] Preferably, the side of the end of the connector is connected to a limiting block 4 that can elastically extend and retract along the direction perpendicular to the insertion. The side wall of the slot 5 is provided with a limiting hole 6 for the limiting block 4 to be inserted. The side of the limiting block 4 facing the bottom of the slot 5 is formed as a slope 11, and the side of the limiting block 4 facing away from the bottom of the slot 5 is formed as a straight surface. When performing step 2 above, the end of the connector is inserted into the corresponding slot 5, so that the end of the slot 5 presses against the slope 11 and causes the limiting block 4 to retract inward. When the limiting block 4 is aligned with the limiting hole 6, the limiting block 4 resets and is locked into the limiting hole 6.
