Description

Technical Field

[0001] This invention relates to the field of vibration damping equipment technology, and specifically to a suspended vibration damper suitable for low-rise buildings. Background Technology

[0002] When low-rise buildings are subjected to earthquakes, the ceiling systems in these buildings are prone to malfunction and loss of function. Therefore, there is a need for a seismic isolation device suitable for low-rise buildings. However, existing seismic isolation devices are relatively complex in structure and installation. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a suspended shock absorber suitable for low-rise buildings.

[0004] This invention proposes a suspended shock absorber suitable for low-rise buildings, comprising a support member, a compression member, a spring, and a connecting member. The two ends of the spring are detachably connected to the support member and the compression member, respectively. The connecting member is connected to the spring and is connected to at least one of the support member and the compression member to limit the spring's movement. One of the compression member and the connecting member can be connected to the ceiling, and the support member can be connected to a hanging element. When at least one of the compression member and the support member is subjected to a compressive force, they move towards each other to compress the spring, causing the spring to shorten. When at least one of the support member and the compression member is subjected to a tensile force, they move towards each other to pull the spring, causing the spring to lengthen.

[0005] Furthermore, the support member includes a support plate, the extrusion member includes an extrusion plate, and also includes a limiting structure for limiting the compression length of the spring. The two ends of the limiting structure are used to abut against the support plate and the extrusion plate respectively when the spring is compressed to a preset length.

[0006] Furthermore, the limiting structure includes a first protective frame fixedly connected to the side of the support plate near the spring, and a first receiving groove formed by the support plate and the first protective frame. A portion of the spring near the support plate can be inserted into the first receiving groove, and the first protective frame is used to protect the portion of the spring near the support plate.

[0007] Furthermore, the area of ​​the support plate is larger than the cross-sectional area of ​​the first protective frame, and the portion of the support plate located outside the projection area of ​​the first protective frame is provided with a first fixing hole, which can be fixedly connected to the hanging component.

[0008] Furthermore, there are multiple first fixing holes arranged symmetrically.

[0009] Furthermore, the limiting structure also includes a second protective frame fixedly connected to the side of the extrusion plate near the spring, and a second receiving groove formed by the extrusion plate and the second protective frame. A portion of the spring near the extrusion plate can be inserted into the second receiving groove, and the second protective frame is used to protect the portion of the spring near the extrusion plate.

[0010] Furthermore, the support plate has a first mounting hole through it, and the extrusion plate has a second mounting hole through it. The axis of the second mounting hole coincides with the axis of the first mounting hole. The connector includes a screw and a stop plate connected to the screw near one end of the extrusion plate. The end of the screw away from the extrusion plate passes through the second mounting hole, the spring, and the first mounting hole in sequence and extends to the side of the support plate away from the spring. The stop plate abuts against the side of the extrusion plate away from the spring. The end of the screw away from the extrusion plate can be fixedly connected to the ceiling.

[0011] Furthermore, the connector also includes a noise-reducing pad for reducing noise generated by the spring, the noise-reducing pad being disposed within the first receiving groove and located on the outer periphery of the spring.

[0012] Furthermore, when neither the compression plate nor the support plate is subjected to external pressure, the spring is in a first state, the axes of the second protective frame and the first protective frame coincide, the cross-sectional area of ​​the second protective frame is larger than the cross-sectional area of ​​the first protective frame, and when the spring is in the first state, the end of the first protective frame away from the support plate is inserted into the second receiving groove.

[0013] Furthermore, the sound-absorbing pad is fixedly connected to the side of the support plate near the spring, and the height of the sound-absorbing pad is less than or equal to the height of the first protective frame.

[0014] The suspended shock absorber of the present invention, suitable for low-rise buildings, has the following beneficial effects:

[0015] The connector can limit the spring to prevent it from tilting during extension and compression. When at least one of the extrusion and support components is subjected to extrusion force, it moves toward each other to compress the spring, causing it to shorten. When at least one of the support and extrusion components is subjected to tension force, it moves toward each other to pull the spring, causing it to extend. The structure is simple and easy to install. The spring can be replaced, and springs with different stiffnesses can be selected, making this application highly applicable, compact in structure, with fewer components, and enhancing the versatility of the components.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0024] Please see Figures 1 to 5An embodiment of the present invention provides a suspended shock absorber suitable for low-rise buildings, comprising a support member 1, a compression member 2, a spring 4, and a connecting member 3. The two ends of the spring 4 are detachably connected to the support member 1 and the compression member 2, respectively. The connecting member 3 is connected to the spring 4 and is connected to at least one of the support member 1 and the compression member 2 to limit the movement of the spring 4. One of the compression member 2 and the connecting member 3 can be connected to a suspended ceiling 5, and the support member 1 can be connected to a hanging member 6. When at least one of the compression member 2 and the support member 1 is subjected to a compressive force, they move towards each other to compress the spring 4, causing the spring 4 to shorten. When at least one of the support member 1 and the compression member 2 is subjected to a tensile force, they move towards each other to pull the spring 4, causing the spring 4 to lengthen.

[0025] Here, the extrusion member 2 and the support member 1 are arranged vertically. The support member 1 is connected to one end of the hanging member 6, and the other end of the hanging member 6 is fixedly connected to the wall and ceiling, thus fixing the support member 1. When either the connecting member 3 or the extrusion member 2 is connected to the ceiling 5, the extrusion member 2 is subjected to extrusion force, causing it to move towards the support member 1. The extrusion member 2 and the support member 1 move towards each other, and the spring 4 is compressed to prevent the ceiling 5 from being squeezed. When the wall and ceiling shake, the wall and ceiling cause the hanging member 6 to move downward, which in turn causes the support member 1 to move downward. The support member 1 is then subjected to tension, and the support member 1 and the extrusion member 2 move away from each other, causing the spring 4 to extend, thus preventing damage to the ceiling 5. This achieves shock absorption for the ceiling 5. When a low-rise building is subjected to earthquakes, this solves or reduces the functional impairment of the ceiling 5, prevents the ceiling 5 from losing its function, and ensures the stable operation of the ceiling 5.

[0026] Specifically, the connector 3 is connected to at least one of the support member 1 and the extruder 2, which can be achieved in the following ways: 1. Holes are provided through the support member 1 and the extruder 2 respectively. One end of the connector 3 is placed on one side of the extruder 2, and the other end passes through the hole on the extruder 2, the spring 4, and the hole on the support member 1 in sequence. The other end of the connector 3 protrudes from one side of the support member 1. A connector 3 of a preset length is selected to ensure that the support member 1 and the extruder 2 are still connected to the connector 3 when the spring 4 is extended to its maximum length; 2. Connectors are provided on the inner side of both the support member 1 and the extruder 2. The connector 3 has one end inserted into the connecting groove on the extruder 2 and the other end passing through the spring 4 and inserted into the connecting groove on the support 1. The connector 3 is selected with a preset length to ensure that the spring 4 is compressed when the extruder 2 and the support 1 are close to each other. When the spring 4 is compressed to its minimum length, at least one of the two ends of the connector 3 does not abut against the bottom wall of the two connecting grooves. When the extruder 2 and the support 1 move in opposite directions, the spring 4 extends. When the spring 4 extends to its maximum length, at least one of the two ends of the connector 3 does not detach from the two connecting grooves.

[0027] Specifically, the two ends of spring 4 are detachably connected to support 1 and compression member 2, respectively, making spring 4 easy to replace. Spring 4 can be a metal spring. Spring 4 is a shock-absorbing spring.

[0028] The axes of the extrusion member 2, the connector 3, the spring 4, and the support member 1 can coincide.

[0029] The support member 1 may include a support plate 11, the extrusion member 2 includes an extrusion plate 21, and also includes a limiting structure for limiting the compression length of the spring 4. The two ends of the limiting structure are used to abut against the support plate 11 and the extrusion plate 21 respectively when the spring 4 is compressed to a preset length.

[0030] Specifically, the extrusion plate 21 can be parallel to the support plate 11. When one of the extrusion plate 21 and the support plate 11 is extruded, the support plate 11 and the extrusion plate 21 move toward each other, and the spring 4 will be compressed. After the spring 4 is compressed to a certain length, the two ends of the limiting structure abut against the support plate 11 and the extrusion plate 21 respectively, and the spring 4 cannot be compressed at this time, thus protecting the spring 4.

[0031] The limiting structure may include a first protective frame 12 fixedly connected to the support plate 11 near one side of the spring 4, and a first receiving groove formed by the support plate 11 and the first protective frame 12. A portion of the spring 4 near the support plate 11 can be inserted into the first receiving groove. The first protective frame 12 is used to protect the portion of the spring 4 near the support plate 11.

[0032] Specifically, the extrusion member 2 and the support member 1 are arranged vertically. The axis of the first protective frame 12, the axis of the first receiving groove, and the axis of the spring 4 coincide, so that the lower part of the spring 4 can be placed in the first receiving groove. The first protective frame 12 is an annular body. At this time, the first protective frame 12 can protect the lower part of the spring 4, and at the same time, the first protective frame 12 can limit the spring 4 when the spring 4 is compressed.

[0033] The area of ​​the support plate 11 can be larger than the cross-sectional area of ​​the first protective frame 12. The part of the support plate 11 located outside the projection area of ​​the first protective frame 12 is provided with a first fixing hole 111, which can be fixedly connected to the hanging part 6.

[0034] Specifically, the first protective frame 12 is perpendicular to the support plate 11, and the support plate 11 is horizontally arranged. The support plate 11 includes a first part on which the first protective frame 12 is projected and a second part located outside the first part. The first fixing hole 111 is provided on the second part of the support plate 11. The hanging member 6 is fixedly connected to the first fixing hole 111, so that one end of the hanging member 6 is fixedly connected to the support plate 11. When the other end of the hanging member 6 is fixedly connected to the top of the wall, the support plate 11 is fixed.

[0035] The first fixing hole 111 can be multiple holes arranged symmetrically.

[0036] Specifically, multiple hanging components 6 are connected to multiple first fixing holes 111, thereby fixing the hanging components 6 and the support plate 11 together and improving the stability of the connection between the hanging components 6 and the support plate 11. The first fixing holes 111 can be two symmetrically arranged, providing greater stability with double-sided fixing.

[0037] The limiting structure may also include a second protective frame 22 fixedly connected to the extrusion plate 21 near one side of the spring 4, and a second receiving groove formed by the extrusion plate 21 and the second protective frame 22. A portion of the spring 4 near the extrusion plate 21 can be inserted into the second receiving groove. The second protective frame 22 is used to protect the portion of the spring 4 near the extrusion plate 21.

[0038] Specifically, the axis of the second protective frame 22, the axis of the second receiving groove, and the axis of the spring 4 coincide, which makes it easy for the upper part of the spring 4 to be placed in the second receiving groove. The second protective frame 22 is an annular body, so at this time the second protective frame 22 can protect the upper part of the spring 4, and at the same time, the second protective frame 22 can also limit the spring 4 when the spring 4 is compressed.

[0039] The support plate 11 has a first mounting hole, and the extrusion plate 21 has a second mounting hole. The axis of the second mounting hole coincides with the axis of the first mounting hole. The connector 3 includes a screw 31 and a stop plate 32 connected to the screw 31 near the end of the extrusion plate 21. The end of the screw 31 away from the extrusion plate 21 passes through the second mounting hole, the spring 4, and the first mounting hole in sequence and extends to the side of the support plate 11 away from the spring 4. The stop plate 32 abuts against the side of the extrusion plate 21 away from the spring 4. The end of the screw 31 away from the extrusion plate 21 can be fixedly connected to the ceiling 5.

[0040] Specifically, a sleeve groove is provided through the inner side of the spring 4. The end of the screw 31 away from the extrusion plate 21 passes through the second mounting hole, the sleeve groove, and the first mounting hole in sequence, and extends to the side of the support plate 11 away from the spring 4. A third mounting hole can be provided on the ceiling 5, which includes a keel. The third mounting hole is provided through the keel. The end of the screw 31 away from the extrusion plate 21 extends out of the outside of the support plate 11 and passes through the third mounting hole. The end of the screw 31 away from the extrusion plate 21 is fixedly connected to the ceiling 5 by two fastening nuts. The stop plate 32 abuts against the side of the extrusion plate 21 away from the spring 4, thereby limiting the extrusion plate 21. By selecting a suitable length of screw 31, when the wall and ceiling are not shaken by external force, the distance between the bottom end of the support plate 11 and the ceiling 5 is a suitable length. This ensures that when the wall and ceiling shake, the length by which the hanging part 6 drives the support plate 11 downward to its maximum length, the support plate 11 still does not abut against the ceiling 5, thus avoiding damage to the ceiling 5.

[0041] The connector 3 may also include a noise-reducing pad 33 for reducing noise generated by the spring 4. The noise-reducing pad 33 is disposed in the first receiving groove and located on the outer periphery of the spring 4.

[0042] Specifically, the noise-absorbing pad 33 can be a rubber pad. The noise-absorbing pad 33 can be a ring-shaped body, and the axis of the noise-absorbing pad 33 coincides with the axis of the first protective frame 12. The noise-absorbing pad 33 is set in the first receiving groove, that is, the noise-absorbing pad 33 is set between the spring 4 and the first protective frame 12, so as to prevent noise from being generated when the spring 4 is in action or reduce the noise generated by the spring 4.

[0043] When neither the pressing plate 21 nor the support plate 11 is subjected to external pressure, the spring 4 is in the first state. The axes of the second protective frame 22 and the first protective frame 12 coincide. The cross-sectional area of ​​the second protective frame 22 is larger than that of the first protective frame 12. When the spring 4 is in the first state, the end of the first protective frame 12 away from the support plate 11 is inserted into the second receiving groove.

[0044] Specifically, the first protective frame 12 and the second protective frame 22 are cut along a plane parallel to the support plate 11, with the cross-sectional area of ​​the second protective frame 22 being larger than that of the first protective frame 12. The first and second protective frames 12 are selected at appropriate heights. When neither the pressing plate 21 nor the support plate 11 is subjected to external pressure, the application is in its initial state, and the spring 4 is in its first state. At this time, the top of the first protective frame 12 is inserted into the second receiving groove, ensuring that the first and second protective frames 12 are not disconnected, thus better protecting the spring 4. When both the pressing plate 21 and / or the support plate 11 are subjected to external force, the spring 4 is stretched to its maximum length, and the spring 4 is in its second state. At this time, the top of the first protective frame 12 is still inserted into the second receiving groove, ensuring that the first and second protective frames 12 are not disconnected when the spring 4 is stretched, thus better protecting the spring 4.

[0045] The sound-absorbing pad 33 can be fixedly connected to the support plate 11 on one side near the spring 4. The height of the sound-absorbing pad 33 is less than or equal to the height of the first protective frame 12.

[0046] Specifically, the sound-absorbing pad 33 is fixedly connected to the top of the support plate 11 to prevent the sound-absorbing pad 33 from moving. The height of the sound-absorbing pad 33 is less than or equal to the height of the first protective frame 12 to prevent the top of the sound-absorbing pad 33 from protruding from the top of the first protective frame 12 and affecting the limiting of the compression of the spring 4 by the first protective frame 12.

[0047] Specifically, the spring 4 is cylindrical, while the first protective frame 12, the second protective frame 22, and the sound-absorbing pad 33 are all annular. The cross-sections of the first protective frame 12 and the second protective frame 22 are circular, as is the cross-section of the sound-absorbing pad 33, thus better matching the spring 4. Alternatively, the first protective frame 12 and the second protective frame 22 can both have square cross-sections.

[0048] Specifically, in this application, the extrusion member 2 and the support member 1 serve as the main load-bearing structures, with the support member 1 and the connector 3 together forming a connection structure with the outside. The metal spring 4 serves as the main damping element, with a rubber pad at its lower part to prevent noise from being generated when the metal spring 4 is in operation. This application uses damping springs 4 with different stiffnesses internally, making it suitable for ceilings 5 ​​with different suspension weights and installation spaces. It has strong applicability and a wide range of applications, reduces the number of components, enhances the versatility of components, and has a compact structure.
