Description

Technical Field

[0001] The present invention belongs to the field of vibration control technology and is applicable to isolating environmental vibrations in high-rise buildings. The device of the present invention not only controls environmental vibrations but also ensures the safety of the building under earthquake action. Background Art

[0002] External environmental vibrations can cause discomfort to people inside buildings, disrupting their normal work and daily lives. They can also damage the building's decorative layers, such as cracking and peeling. Long-term, high-intensity vibrations can also cause structural damage, such as wall cracks and foundation deformation and subsidence.

[0003] Installing vibration isolation supports between a building structure and its foundation effectively isolates the propagation of external vibrations into the building. However, in tall buildings, due to their large height-to-width ratio, earthquakes often place significant tensile stresses on the vertical components of the structure. Currently, commonly used vibration isolation supports lack sufficient tensile strength. Ensuring that these supports effectively isolate vertical vibrations while ensuring structural safety during earthquakes remains an international challenge in the field of vibration control. Summary of the Invention

[0004] The present invention aims to provide a vibration isolation device which can isolate vibration, eliminate structure-borne sound and has large pull-out resistance and horizontal bearing capacity, and is suitable for high-rise buildings in earthquake zones.

[0005] The present invention is implemented by adopting the following technical solutions.

[0006] A tensile vibration isolation device, comprising a lower connecting member 2, an upper connecting member 1, an anti-pulling mechanism, and a limiting ring mechanism;

[0007] The upper connecting piece 1 and the lower connecting piece 2 are arranged in a knotted manner, and the anti-pullout mechanism is arranged between the upper connecting piece 1 and the lower connecting piece 2 to prevent the upper connecting piece 1 and the lower connecting piece 2 from separating; the limiting ring mechanism is arranged on the lower connecting piece 2.

[0009] The upper portion of the upper connecting member 1 is provided with a groove for accommodating the tensile plate 4.

[0010] A tensile elastic body is provided between the tensile plate 4 and the upper connecting member 1;

[0011] A threaded through hole is provided at the center of the tensile plate 4;

[0012] The tensile shaft 3 passes through the lower connecting piece 2 and is threadedly connected to the tensile plate 4 .

[0013] The limiting ring mechanism of the present invention is composed of a plurality of limiting ring hoops 8, which form a circular ring shape and are connected in pairs to form a ring through ring hoop connectors 11;

[0014] The present invention also includes an elastic component, which includes an elastic body and a steel plate. A plurality of elastic bodies and a plurality of steel plates are sequentially superimposed and fixedly connected; the elastic component is arranged between the upper connecting member 1 and the lower connecting member 2.

[0015] The present invention also includes a prestressed elastic ring; the prestressed elastic ring is arranged at the knotted position between the upper connecting member 1 and the lower connecting member 2; the upper connecting member 1 and the lower connecting member 2 are horizontally isolated.

[0016] The upper end surface of the limiting ring hoop 8 of the limiting ring mechanism of the present invention is further provided with a hoop elastic body.

[0017] The upper part of the upper connecting member 1 of the present invention is provided with an upper embedded plate 12a, and the upper part of the upper embedded plate 12a is provided with an upper embedded sleeve 13a and an upper embedded rod 14a in sequence from bottom to top; an upper shear member 16 is further provided between the upper embedded plate 12a and the upper connecting member 1;

[0018] A lower embedded plate 12b is provided at the lower portion of the lower connecting member 2, and a lower embedded sleeve 13b and a lower embedded rod 14b are provided at the lower portion of the lower embedded plate 12b in sequence from top to bottom; a lower shear member 17 is further provided between the lower embedded plate 12b and the lower connecting member 2.

[0019] The lower end surface of the tensile shaft 3 described in the present invention is configured as a regular polygon, and the lower connecting member 2 is matched with the lower end surface of the tensile shaft 3 .

[0020] The upper portion of the lower connecting member 2 of the present invention is arranged in a circular shape, and a convex stop A is arranged concentrically on the upper end surface thereof; the elastic component is arranged at the convex stop A.

[0021] The lower portion of the upper connecting member 1 of the present invention is circular, and a circular cavity is concentrically processed on its lower end surface, and a convex stop B is concentrically processed on the circular cavity of the lower end surface; the prestressed elastic ring is arranged at the convex stop B.

[0022] The beneficial effects of the present invention are as follows: (1) the tensile vibration isolation device proposed in this patent can be used in combination with multiple devices, and the number of models and arrangements can be flexibly selected according to the load distribution of the building structure.

[0023] (2) Vibration isolation effect: The upper connector 1 connected to the building structure and the lower connector 2 connected to the foundation or non-protective structure are vertically flexibly isolated through the vibration isolation rubber 5. The vibration isolation rubber 5 mainly plays the role of adjusting the frequency, isolating vibration and eliminating solid noise. It isolates vibration through its own vertical reciprocating deformation. Since the horizontal rubber ring 7 is made of a polymer elastic material and its extrusion amount is controlled within the set range, the vertical stiffness is small. Compared with the vertical stiffness of the vibration isolation rubber 5, the vertical stiffness of the horizontal rubber ring 7 is negligible. The tensile shaft 3, the tensile plate 4 and the tensile rubber 6 form an anti-pulling mechanism, and are placed on the upper connector 1 through the tensile rubber 6, which is equivalent to flexible isolation between the tensile mechanism and the upper connector 1, and does not affect the normal operation of the vibration isolation device.

[0024] (3) Anti-pullout function: The tensile shaft 3, tensile plate 4 and tensile rubber 6 form an anti-pullout mechanism. When the upper pier 18 generates an upward pulling force, the upper connector 1 fixedly connected to it is also subjected to an upward pulling force. At this time, the upper connector 1 transmits the pulling force to the tensile plate 4 through the tensile rubber 6. The tensile plate 4 transmits the pulling force to the tensile shaft 3 connected to it by a serrated thread. Since the tensile shaft 3 is restricted from upward movement by the lower connector 2, the tensile shaft 3 transmits the pulling force to the lower connector 2. The lower connector 2 transmits the pulling force to the lower pier 19 fixed to it, thus realizing the overall anti-pullout function. At the same time, the tensile rubber 6 can be compressed as an elastic body to achieve a buffering effect.

[0025] (4) Integrated protection and isolation measures: A horizontal rubber ring 7 is provided between the upper connector 1 and the lower connector 2. The horizontal rubber ring 7 is appropriately squeezed as needed to form a prestressed state, thereby ensuring the integrity of the vibration isolation device. When the vibration isolation device is subjected to a horizontal load, the horizontal rubber ring 7 can also achieve horizontal load transfer between the upper connector 1 and the lower connector 2.

[0026] (5) Vertical limiting function: The limiting ring mechanism of the vibration isolation device proposed in this patent is a post-installed component, that is, it is installed after the high-rise building structure is completed and the upper static load is in a stable state. The purpose is to operate the limiting ring mechanism when the upper connecting member produces a downward displacement exceeding the set displacement to control the vertical deformation of the vibration isolation device. The hoop rubber 9 on the limiting ring mechanism improves the vertical stiffness of the vibration isolation device.

[0027] When used on high-rise building structures, high-rise building structures are prone to generating large overturning moments under the action of earthquakes, that is, the vibration isolation device on one side is subjected to an upward dynamic load, and the vibration isolation device on the other side is subjected to a downward dynamic load. When the vibration isolation device is subjected to an upward dynamic load, it is easy to enter a tensile state. In this state, the upward limit is achieved by the tensile mechanism. When the vibration isolation device is subjected to a downward dynamic load, the upper connecting member 1 moves downward, but because there is only a normal working gap reserved between the lower end face of the upper connecting member 1 and the hoop rubber 9 of the limiting ring mechanism, when the lower end face of the upper connecting member 1 moves downward beyond this gap, the limiting ring mechanism controls the vertical movement of the upper connecting member 1, and the hoop rubber 9 increases the vertical stiffness of the vibration isolation device.

[0041] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 shown.

[0043] Example 1:

[0044] A tensile vibration isolation device includes a set of elastic components, a lower connecting member 2, an upper connecting member 1, a prestressed elastic ring, a set of anti-pulling mechanisms and a set of limiting ring mechanisms;

[0045] The upper connecting member 1 and the lower connecting member 2 are circular or square in shape.

[0046] The elastic component is circular or square in shape with a circular hole in the middle. It is composed of an elastic body [such as vibration isolation rubber 5] and a steel plate. Multiple elastic bodies and multiple steel plates are sequentially superimposed and fixed.

[0047] The elastic component is concentrically mounted on the lower connecting member 2, and the lower connecting member 2 is connected to the non-protective structure.

[0048] The upper connecting member 1 is concentrically mounted on the elastic component. The upper connecting member 1 is connected to the protected structure. The elastic component can adjust the frequency, isolate vibration and eliminate solid noise under pressure.

[0049] The anti-pullout mechanism passes through the upper connecting member 1 and the lower connecting member 2. When the upper connecting member 1 and the lower connecting member 2 are in tension, the anti-pullout mechanism works to prevent the upper connecting member 1 and the lower connecting member 2 from separating.

[0050] The prestressed elastic ring is horizontally arranged between the upper connecting member 1 and the lower connecting member 2 to horizontally isolate the upper connecting member 1 and the lower connecting member 2. Moreover, when the vibration isolation device is subjected to a horizontal load, the horizontal load transfer function is achieved;

[0051] The limit ring mechanism is horizontally arranged on the lower connecting member 2. When the upper connecting member 1 produces a downward displacement exceeding a set value, the limit ring mechanism works to increase the vertical stiffness of the vibration isolation device and control the vertical deformation of the vibration isolation device.

[0052] The anti-pulling mechanism includes a tensile shaft 3, a tensile plate 4 and a tensile elastic body [such as tensile rubber 6];

[0053] The tensile elastic body is concentrically mounted on the upper connecting member 1.

[0054] When the vibration isolation device changes from a compressed state to a tensile state, the tensile elastic body works to prevent impact;

[0055] At the same time, when multiple devices of the present patent application are used in a building, the elastic body can coordinate the tensile function of each device.

[0056] The tensile plate 4 is concentrically arranged on the tensile elastic body, and a threaded through hole is provided at the center of the tensile plate 4 .

[0057] The tensile shaft 3 passes through the lower connecting piece 2 , the elastic component and the upper connecting piece 1 in sequence from bottom to top and is threadedly connected to the tensile plate 4 .

[0058] The lower end of the tensile shaft 3 is mounted on the lower connecting member 2 from bottom to top.

[0059] The prestressed elastic ring [such as the tensile rubber 6] can generate prestress by being squeezed and deformed between the upper connecting member 1 and the lower connecting member 2. The generated prestress can be 0 to 10 MPa.

[0060] The limiting ring mechanism is composed of a plurality of limiting ring hoops 8 , which form a circular ring shape and are connected in pairs to form a ring through ring hoop connectors 11 .

[0061] The upper end surface of the limiting ring hoop 8 of the limiting ring mechanism is also provided with a hoop elastic body [such as: hoop rubber 9], which plays a buffering role when the upper connecting member 1 contacts the limiting ring mechanism and provides greater vertical rigidity for the device.

[0062] The protected structure is connected to the upper connecting member 1 via the upper embedded plate 12a.

[0063] The upper embedded plate 12a is fixedly connected to the upper column pier 18 of the protected structure.

[0064] At the same time, an upper shear member 16 is provided between the upper embedded plate 12a and the upper connecting member 1;

[0065] Similarly, the non-protective structure and the lower connecting member 2 are connected via a lower embedded plate 12b, which is fixedly connected to the lower pier 19 of the non-protective structure. A lower shear member 17 is also provided between the lower embedded plate 12b and the lower connecting member 2.

[0066] The thread between the tensile shaft 3 and the tensile plate 4 may also be a sawtooth thread.

[0067] The lower end face of the tensile shaft 3 can also be a regular polygon. At the same time, the lower connecting member 2 is also a matching regular polygon, so that when the tensile shaft 3 is installed on the lower connecting member 2 from bottom to top, the rotation of the tensile shaft 3 is restricted to achieve the anti-loosening function.

[0068] There is a distance between the limiting ring mechanism and the lower end surface of the upper connecting member 1. The distance meets the working performance requirements of the device and is determined based on design and calculation.

[0069] The upper end surface of the lower shear member 17 has a concave platform that is larger than the lower end surface plane of the tensile shaft 3. The depth of the concave platform meets the working performance requirements of the device and is determined based on design and calculation.

[0070] Example 2:

[0071] A tensile vibration isolation device consists of an upper connecting piece 1, a lower connecting piece 2, a tensile shaft 3, a tensile plate 4, a vibration isolation rubber 5, a tensile rubber 6, a horizontal rubber ring 7, a limiting hoop 8, a hoop rubber 9, a hoop bolt 10, and a hoop connecting piece 11.

[0072] The vibration isolation rubber 5 is an annular laminated rubber, comprising two layers of rubber rings, two steel ring plates at the upper and lower end faces, and a steel ring plate in the middle, wherein the rubber rings are placed between the steel ring plates.

[0073] The lower portion of the lower connecting member 2 is square with round holes at the four corners. The connecting bolts 15 pass through the round holes of the lower connecting member 2 to connect the lower connecting member 2 to the lower column pier 19 .

[0074] The upper part of the lower connecting piece 2 is circular, and a convex stop A is concentrically processed on its upper end surface.

[0075] The inner circle of the vibration isolation rubber 5 is coaxially mounted with the convex stop A and is arranged on the upper end surface of the lower connecting member 2 .

[0076] The center of the lower connecting member 2 is processed with a circular hole that passes through the upper and lower end surfaces. At the same time, the lower end surface of the lower connecting member 2 is also processed with two levels of concave platforms, the first level concave platform is a circular concave platform, and the second level concave platform is a square concave platform.

[0077] The upper portion of the upper connecting member 1 is square with round holes at the four corners. The connecting bolts 15 connect the upper connecting member 1 to the upper column pier 18 through the round holes of the upper connecting member 1 .

[0078] The lower part of the upper connecting member 1 is circular, and a circular concave cavity is concentrically processed on its lower end face, and a convex stop B is concentrically processed on the circular concave cavity of the lower end face. The upper connecting member 1 is concentrically arranged on the upper end face of the vibration isolation rubber 5, and the vibration isolation rubber 5 is inserted into the circular concave cavity of the lower end face of the upper connecting member 1, and the inner circle of the vibration isolation rubber 5 is concentrically matched with the convex stop B of the circular concave cavity of the lower end face of the upper connecting member 1.

[0079] The upper end face of the upper connector 1 is also concentrically machined with a circular cavity, and the circular cavity of the upper end face is also concentrically machined with a convex stop B. The tensile rubber 6 is a circular rubber sheet, which is arranged on the circular cavity of the upper end face of the upper connector 1, and the inner ring of the tensile rubber 6 is concentrically mounted with the convex stop B on the circular cavity of the upper end face.

[0080] A circular hole is machined at the center of the upper connecting piece 1 and passes through the upper and lower end surfaces.

[0081] A circle of the horizontal rubber ring 7 is bonded or vulcanized on the outer circle of the upper end face of the lower connecting member 2. The cross section of the horizontal rubber ring 7 is a "7" shape. The horizontal portion of the cross section of the horizontal rubber ring 7 is bonded or vulcanized to the upper end face of the lower connecting member 2, and the vertical portion is bonded or vulcanized to the outer cylindrical surface of the lower connecting member 2. At the same time, the upper connecting member 1 is installed, and the inner wall of the circular concave cavity of the lower end face of the upper connecting member 1 is also inserted into the outer cylindrical surface of the horizontal rubber ring 7. That is, the horizontal rubber ring 7 is set between the inner wall of the circular concave cavity of the lower end face of the upper connecting member 1 and the outer cylindrical surface of the lower connecting member 2, so that the horizontal load can be transferred between the upper connecting member 1 and the lower connecting member 2. At the same time, the horizontal rubber ring 7 can be prestressed by adjusting the diameter of the horizontal rubber ring 7 as needed.

[0082] As attached Figure 4As shown, one end of the circular shaft of the tensile shaft 3 is processed with a serrated external thread, and the other end is processed with a square boss. The square boss is coaxially arranged with the circular shaft. The diameter of the circular shaft is smaller than the diameter of the through hole in the center of the upper connecting member 1 and the lower connecting member 2, and the thickness of the square boss is slightly smaller than the second-level concave platform on the lower end face of the lower connecting member 2 is a square concave platform.

[0083] The threaded end of the tensile shaft 3 is installed upward from the bottom surface of the lower connecting member 2 through the through hole. At the same time, the square boss of the tensile shaft 3 is embedded in the square concave platform of the lower connecting member 2, and the end of the tensile shaft 3 with a serrated external thread passes through the circular concave platform on the upper end surface of the upper connecting member 1.

[0084] The tensile plate 4 is annular, and its inner circle is processed with a serrated internal thread that matches the serrated external thread of the tensile shaft 3. The tensile plate 4 is threadedly connected to the tensile shaft 3, and the tensile plate 4 is placed on the tensile rubber 6.

[0085] The upper end surface of the tensile plate 4 is processed with an annular hole for fastening.

[0086] The weight of the building structure, or static load, is transferred to the upper connector 1 via the upper pier 18. The upper connector 1 then transfers the static load to the lower connector 2 via the vibration-isolating rubber 5. The lower connector 2 then transfers the static load to the lower pier 19. During this process, the vibration-isolating rubber 5 is compressed and deformed under the load, ultimately reaching a stable state. Specifically, the distance between the lower end face of the upper connector 1 and the upper end face of the square plate of the lower connector 2 remains relatively stable. At this point, six limiting hoops 8 are installed on the upper end face of the square plate of the lower connector 2 to form a limiting ring, which fits over the outer cylindrical surface of the lower connector 2.

[0087] The limiting hoops 8 are connected in pairs by hoop bolts 10 and hoop connectors 11 to form a circular ring. At the same time, a hoop rubber 9 of equal thickness is bonded or vulcanized to the upper end face of each limiting hoops 8. When installed, the hoop rubber 9 faces upward and faces the end face of the upper connector 1 with a certain gap therebetween.

[0088] The upper embedded plate 12a is cast integrally with the upper column pier 18. A circular through-hole is formed in the center of the upper embedded plate 12a. The diameter of the circular through-hole is larger than the diameter of the circular concave cavity on the upper end face of the upper connector 1. Conversely, a concave stopper with a diameter equivalent to the circular through-hole of the upper embedded plate 12a is concentrically machined at the opening of the circular concave cavity on the upper end face of the upper connector 1. The upper shear member 16 is cylindrical, with an outer diameter equivalent to the diameter of the circular through-hole of the upper embedded plate 12a. The upper shear member 16 is simultaneously embedded in the concave stopper of the circular concave cavity on the upper end face of the upper connector 1 and the circular through-hole of the upper embedded plate 12a, thereby achieving horizontal shear resistance between the upper connector 1 and the upper embedded plate 12a.

[0089] The embedded plate 12b is cast integrally with the lower column pier 19. A circular through-hole, concentrically machined in the center of the embedded plate 12b, is sized to match the diameter of the circular concave portion of the lower end face of the lower connector 2. The lower shear member 17 is cylindrical, with an outer diameter corresponding to the diameter of the circular through-hole of the embedded plate 12b. The lower shear member 17 is embedded in both the circular concave portion of the lower end face of the lower connector 2 and the circular through-hole of the embedded plate 12b, providing horizontal shear resistance between the lower connector 2 and the embedded plate 12b.

[0090] A circular concave portion is formed at the center of the upper end surface of the lower shear member 17. The diameter of the concave portion is greater than the diagonal length of the plane of the square boss at the lower end of the tensile shaft 3. The depth of the concave portion is greater than the gap between the rubber hoop 9 and the lower end surface of the upper connector 1.

[0091] The four corners of the upper embedded plate 12a are processed with circular holes corresponding to the four corner circular holes of the upper connecting member 1, and the diameter of the circular holes is larger than the diameter of the four corner circular holes of the upper connecting member 1. The upper embedded sleeve 13a is processed with internal threads inside, and a circular boss is processed at one end. The upper embedded sleeve 13a embeds the circular boss into the four corner circular holes of the upper embedded plate 12a, and the contact part of the upper embedded sleeve 13a and the upper embedded plate 12a is fixed by welding. The connecting bolt 15 connects the upper connecting member 1 and the upper embedded plate 12a by threading with the upper embedded sleeve 13a. One end of the upper embedded rod 14a is processed with external threads and is threadedly connected to the upper embedded sleeve 13a, and the other end is processed with a circular boss. At the same time, each embedded component is connected to the steel bars of the upper column pier 18 according to the specifications (the steel bars of the upper column pier 18 are not drawn in the accompanying drawings).

[0092] The four corners of the lower embedded plate 12b are processed with circular holes corresponding to the four corner circular holes of the lower connecting member 2, and the diameter of the circular holes is larger than the diameter of the four corner circular holes of the lower connecting member 2. The lower embedded sleeve 13b is processed with internal threads inside, and a circular boss is processed at one end. The lower embedded sleeve 13b embeds the circular boss into the four corner circular holes of the lower embedded plate 12b, and the contact part of the lower embedded sleeve 13b and the lower embedded plate 12b is fixed by welding. The connecting bolt 15 connects the lower connecting member 2 and the lower embedded plate 12b by threading with the lower embedded sleeve 13b. One end of the lower embedded rod 14b is processed with external threads and is threadedly connected to the lower embedded sleeve 13b, and the other end is processed with a circular boss. At the same time, each embedded component is connected to the steel bars of the lower column pier 19 according to the specifications (the steel bars of the lower column pier 19 are not drawn in the attached figure).
