Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering technology, specifically to an anti-overturning vibration isolation building. Background Technology
[0002] In recent years, subways have become the preferred mode of transportation for many urban residents due to their large capacity, high speed, and lack of traffic congestion. Subway stations, with their high passenger volume and concentrated population, exhibit significant commercial value. Therefore, many cities have begun investing in exploring the commercial potential of properties above subway stations, achieving substantial economic benefits. To further improve intensive land use, subway-related properties often include numerous high-rise buildings. To enhance the environmental comfort of these properties and prevent adverse effects of subway vibrations on residents, vibration isolation measures are typically implemented for sensitive areas, such as the enhanced vibration isolation components described in patent publication number CN117005551A. However, taller vibration-isolated buildings, especially high-rise buildings using steel spring vibration isolation, experience significant horizontal swaying during strong winds and earthquakes, affecting comfort and safety during major earthquakes. This also significantly limits the overall height of the building structure, negatively impacting economic viability.
[0003] In conclusion, the market urgently needs a vibration-isolated building structure that offers higher land utilization, better comfort, safety, and economy. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned defects and provide an anti-overturning and vibration isolation building that can effectively improve the limitations of floor height, comfort, safety and economy.
[0005] This utility model of an anti-overturning vibration isolation building is implemented as follows: It includes a vibration isolation building body supported on a foundation by elastic vibration isolation devices, an external support structure, and an anti-overturning structure. The external support structure includes soil and rock around the vibration isolation building body, a retaining wall, or an external support structure fixedly connected to the ground foundation. The anti-overturning structure includes at least two layers of horizontal elastic support groups arranged vertically between the vibration isolation building body and the external support structure. The lower layer of horizontal elastic support group is located between the bottom floor slab of the vibration isolation building body and the external support structure, while the upper layer of horizontal elastic support group is located between the highest floor slab of the vibration isolation building body within the height range of the external support structure and the external support structure. Each horizontal elastic support group includes multiple horizontal elastic support devices spaced apart in the horizontal direction, with each horizontal elastic support device corresponding to at least two long sides of the vibration isolation building body between the external support structure and the external support structure.
[0006] The lateral elastic support device includes a housing and an elastic element, wherein the elastic element includes at least one of a helical steel spring, a disc spring, a leaf spring, a rubber elastomer, or a polyurethane elastomer.
[0007] The lateral elastic support device of this invention may further include a pre-tightening structure, which includes a pre-tightening adjusting shim and / or a pre-tightening shoulder. If necessary, a pre-tightening adjusting rod and a locking nut may also be provided on the pre-tightening shoulder.
[0008] To ensure that the vibration-isolated building body has reliable anti-overturning capability during an earthquake, while also having good vertical vibration reduction capability under normal use conditions, a vertical sliding friction pair with a friction coefficient of less than 0.12 can be set in the lateral elastic support device of this utility model, or a vertical sliding friction pair with a friction coefficient of less than 0.12 can be set between the lateral elastic support device and the outer supporting building, or a vertical sliding friction pair with a friction coefficient of less than 0.12 can be set between the lateral elastic support device and the vibration-isolated building body.
[0009] In addition, to prevent solid-borne acoustic short circuits or vibration short circuits, a sound-insulating elastic layer can be installed in the lateral elastic support device, or between the lateral elastic support device and the surrounding supporting building, or between the lateral elastic support device and the vibration-isolated building body. Generally, the sound-insulating elastic layer is made of a polymer elastic material.
[0010] To improve energy dissipation, damping elements can also be incorporated into the lateral elastic support device. These damping elements include orifice throttling dampers, eddy current dampers, viscous dampers, viscous elastic dampers, or friction dampers. As an exception, the damping element and the elastic element can be the same component.
[0011] Preferably, the external support structure adopts a horizontal shear-strengthened design.
[0012] The anti-overturning vibration isolation building of this utility model may also include an equalizing plate, which is fixedly installed on the main body of the vibration isolation building and / or the surrounding supporting building, and the equalizing plate is correspondingly installed with the lateral elastic support device. Typically, the equalizing plate can be fixedly installed on the main body of the vibration isolation building and / or the surrounding supporting building in the form of a pre-embedded steel plate.
[0013] This utility model relates to an anti-overturning vibration isolation building. By setting up an outer supporting building and an anti-overturning structure around the vibration isolation building body, the anti-overturning structure includes at least two layers of transverse elastic support groups arranged vertically between the vibration isolation building body and the outer supporting building. This provides the following main advantages: 1) The transverse elastic support devices in the transverse elastic support groups provide transverse elasticity, effectively preventing vibration short circuits and further improving the vibration isolation effect; 2) The transverse stiffness and damping provided by the transverse elastic support devices in the transverse elastic support groups can reduce the horizontal swaying or swinging amplitude of the vibration isolation building body during strong winds or earthquakes, effectively preventing the vibration isolation building body from overturning, improving the seismic resistance of the vibration isolation building body, making it safer and more reliable, and thus effectively increasing the height limit of the vibration isolation building; 3) The transverse elastic support devices in the transverse elastic support groups ensure that the vibration isolation performance of the elastic vibration isolation device is fully utilized, while also giving the vibration isolation building body good anti-seismic overturning capability, truly achieving a dual vibration control effect.
[0014] It should be noted that the horizontal and vertical directions mentioned in this utility model refer to the vibration isolation building body. The vertical direction corresponds to the vertical direction of the vibration isolation building body, and the horizontal direction corresponds to the horizontal direction of the vibration isolation building body.
[0015] In summary, this utility model of anti-overturning vibration isolation building can significantly improve the safety and reliability of the main body of the vibration isolation building during earthquakes. It has good vibration and seismic control performance, simple structure, good economy, high cost performance, and safety and reliability. It can be widely used in various vibration isolation building projects with external support structures. Attached Figure Description

[0032] Example 1
[0033] like Figure 1 , Figure 2 and Figure 3The present invention, a vibration-isolated anti-overturning structure, includes a vibration-isolated building body 1, which is supported on a foundation by an elastic vibration isolation device 4. The vibration-isolated building body 1 is a subway-adjacent property. The foundation includes a ground foundation 3 and a base plate 5 above a tunnel (not specifically shown in the figure). It also includes an external support structure and an anti-overturning structure. The external support structure is specifically an external support building 2 fixedly connected to the ground foundation 3. The external support building 2 is correspondingly located on the outer side of the long side of the vibration-isolated building body 1, and has an underground fixed structure embedded in the ground foundation 3. The anti-overturning structure... The structure includes two layers of horizontal elastic support groups arranged vertically between the vibration-isolated building body 1 and the outer supporting building 2. The lower layer of horizontal elastic support group is located between the bottom floor slab 7 of the vibration-isolated building body 1 and the outer supporting building 2. The upper layer of horizontal elastic support group is located between the highest floor slab 7 of the vibration-isolated building body 1 and the outer supporting building 2 within the height range of the outer supporting building. The horizontal elastic support group includes multiple horizontal elastic support devices 6 arranged at intervals in the horizontal direction. The horizontal elastic support devices are correspondingly arranged between the two long sides of the vibration-isolated building body 1 and the outer supporting building 2. The horizontal elastic support device 6 includes a shell and an elastic element 8. The shell includes an inner shell 9 and an outer shell 10. The inner shell 9 is in contact with the floor slab 7, and the outer shell 10 is in contact with the outer supporting building 2. The elastic element 8 is specifically a helical steel spring.
[0034] It should be noted that in engineering applications, after the transverse elastic support device 6 is installed, anchor bolts (not specifically shown in the figure) can be installed on the floor slab 7 and / or the outer supporting building 2 to fix the transverse elastic support device 6 and prevent it from accidentally slipping and falling off. Of course, other protruding and concave structures can also be set on the floor slab or the outer supporting building to limit the transverse elastic support device. These are some conventional measures in engineering, which are only explained in words here and no additional figures are attached.
[0035] Compared with existing technologies, this utility model of an anti-overturning vibration isolation building, by setting up an outer supporting building and an anti-overturning structure around the vibration isolation building body, wherein the anti-overturning structure includes at least two layers of transverse elastic support groups arranged vertically between the vibration isolation building body and the outer supporting building, can bring the following main advantages: 1) Utilizing the elastic deformation capability of the elastic elements in the transverse elastic support device in the vertical direction of the vibration isolation building body, it can ensure that the elastic vibration isolation device can normally perform its vibration isolation function on the vibration isolation building body. At the same time, the transverse elastic support device in the transverse elastic support group provides transverse elasticity, which can effectively avoid vibration short circuits and further improve the vibration isolation of the elastic vibration isolation device on the vibration isolation building body. 1) Vibration control effect; 2) By utilizing the lateral stiffness provided by the lateral elastic support device in the lateral elastic support group, the swaying or swinging amplitude of the vibration isolation building body along its short side in the horizontal direction (i.e., lateral) during strong winds or earthquakes can be effectively limited, thereby improving the comfort of the vibration isolation building, effectively preventing the overturning of the vibration isolation building body, improving the stability and seismic resistance of the vibration isolation building body, making it safer and more reliable, and thus effectively increasing the height limit of the vibration isolation building; 3) By utilizing the lateral elastic support device in the lateral elastic support group, the vibration isolation performance of the elastic vibration isolation device can be fully utilized, while enabling the vibration isolation building body to have good seismic overturning resistance, truly achieving the dual control effect of vibration and seismicity.
[0036] It should be noted that the terms "horizontal" and "vertical" in this utility model refer specifically to the vibration-isolated building body. "Vertical" corresponds to the vertical direction of the vibration-isolated building body, and "horizontal" corresponds to the horizontal direction. Furthermore, this example uses a subway-adjacent property as an example of a vibration-isolated building body. In practice, however, the vibration-isolated building body can also be other building structures that employ vibration isolation technology and are not convenient for underground fixed structures; these are also within the scope of protection claimed by this utility model.
[0037] In summary, this utility model of anti-overturning vibration isolation building can significantly improve the safety and reliability of the main body of the vibration isolation building during earthquakes. It has good vibration and seismic control performance, simple structure, good economy, high cost performance, and safety and reliability. It can be widely used in various vibration isolation building projects with external support structures.
[0038] It should be noted that, in this utility model, the elastic element in the transverse elastic support device can be not only the helical steel spring mentioned above, but also other types of elastic elements such as disc springs, leaf springs, rubber elastomers, or polyurethane elastomers, which can also achieve good technical effects. In practice, the appropriate element can be selected according to the engineering needs. Furthermore, this example uses an external support structure fixed to the ground foundation as an example. In actual engineering, depending on the type of vibration-isolated building, the external support structure can also be the surrounding rock and soil or retaining walls, etc., achieving the same technical effect. These are simple variations based on the technical principles of this utility model, and are described in words only without accompanying drawings, all within the scope of protection claimed by this utility model.
[0039] Example 2
[0040] like Figure 4 The anti-overturning vibration isolation building shown in this utility model differs from Embodiment 1 in that the lateral elastic support device 6 further includes a pre-tightening structure. Specifically, the pre-tightening structure is a pre-tightening adjustment shim 14, which is made of steel plate and is disposed between the outer shell 10 and the outer supporting building 2. The outer shell 10 and the pre-tightening adjustment shim 14 are fixed together to the outer supporting building 2 using fasteners 15.
[0041] Compared to Embodiment 1, the technical solution described in this example incorporates pre-tightening adjustment shims. On one hand, these shims can compensate for dimensional errors caused during construction. On the other hand, they can pre-compress the elastic elements in the lateral elastic support device, allowing the elastic restoring force output by the lateral elastic support device to react on the vibration-isolated building body, ensuring a tight fit between the lateral elastic support device and the vibration-isolated building body under normal operating conditions. Furthermore, since the outer shell of the lateral elastic support device is fixed to the surrounding supporting building with fasteners, it ensures that the lateral elastic support device will not slip unexpectedly. The structure is simple, safe, and reliable.
[0042] Of course, based on the technical principle of this example, the pre-tightening adjustment shim can also be placed between the inner shell and the floor slab to achieve the same technical effect. This is only described in words and will not be shown in any additional drawings. It is also within the protection scope of this utility model.
[0043] Example 3
[0044] like Figure 5 and Figure 6The anti-overturning vibration isolation building of this utility model differs from Embodiment 2 in that the outer supporting building 2 is arranged around the vibration isolation building body 1, and anti-overturning structures are simultaneously arranged between the long and short sides of the vibration isolation building body 1 and the outer supporting building 2. The lateral elastic support device 6 in the lateral elastic support group is also simultaneously arranged between the long side of the vibration isolation building body 1 and the outer supporting building 2, and between the short side of the vibration isolation building body 1 and the outer supporting building 2. Furthermore, the lateral elastic support device 6 also includes a pre-tightening structure, which includes pre-tightening shoulders 11 correspondingly arranged on the inner shell 9 and the outer shell 10, and pre-tightening adjusting rods 13 and locking nuts 12 arranged on the pre-tightening shoulders 11. In addition, the lateral elastic support device 6 also includes a damping element 16, specifically a small-hole throttling damper.
[0045] Compared with Embodiment 1, in the technical solution described in this example, since anti-overturning structures are simultaneously set between the long and short sides of the vibration-isolated building body and the surrounding supporting building, the swaying or swinging amplitude of the vibration-isolated building body along its long and short sides in the horizontal direction (i.e., laterally) can be effectively limited when strong winds or earthquakes occur, thereby effectively preventing the vibration-isolated building body from overturning and further improving the stability and wind and earthquake resistance of the vibration-isolated building body. Since damping elements are added to the lateral elastic support device, the lateral elastic support device can not only provide lateral stiffness but also provide damping. Therefore, the energy dissipation capacity of the lateral elastic support device is stronger. It can better isolate vibrations and effectively dissipate the external impact energy transmitted by the surrounding supporting building, thereby significantly reducing the impact impact on the vibration-isolated building body and making it safer and more reliable. Furthermore, the use of the pre-tightening adjustment rod 13, the locking nut 12, and the pre-tightening shoulder 11 for fixed connection facilitates the use and transportation of the transverse elastic support device 6. In engineering applications, after the transverse elastic support device 6 is installed, the locking nut 12 can be loosened, allowing the transverse elastic support device 6 to be in a free working state. The significance of retaining the pre-tightening adjustment rod 13 and the locking nut 12 is twofold. Firstly, when the transverse elastic support device 6 needs to be removed, the locking nut 12 can be tightened again to compress the transverse elastic support device 6, causing the shell of the transverse elastic support device 6 to disengage from the floor slab and the surrounding supporting structure, making it convenient to remove the transverse elastic support device 6 for maintenance, replacement, and other operations. Secondly, when extreme situations such as earthquakes occur and the relative position of the surrounding supporting structure and the floor slab changes, the elastic element 8 in the transverse elastic support device 6 can automatically rebound to compensate for this spacing change. Due to the presence of the pre-tightening adjustment rod 13 and the locking nut 12, the range of spacing change between the inner shell and the outer shell can be controlled, avoiding problems such as the elastic element tipping over and falling off due to excessive spacing changes, making it safer and more reliable.
[0046] Of course, based on the technical principles of this example, a preload shoulder can also be provided only on the inner or outer shell, for example... Figure 7 As shown, only the outer shell 10 is provided with a pre-tightening shoulder 11. The pre-tightening adjusting rod 13, which is composed of fasteners, cooperates with the pre-tightening shoulder 11 to fix the inner shell 9, the outer shell 10 and the floor slab 7 together. After the elastic element is pre-tightened and compressed to the position, the inner shell 9 and the floor slab 7 are locked together by the locking nut 12, which can also achieve a good technical effect. In addition, in addition to the small-hole throttling damper, the damping element can also adopt other forms of damping structure such as eddy current damper, viscous damper, viscous elastic damper or friction damper, which can also achieve a good effect. In practice, it can be selected according to needs. Here, only the text is given as an explanation, and no additional drawings are provided. These are all simple changes based on the technical principle of this utility model, and they are all within the protection scope of this utility model.
[0047] Example 4
[0048] like Figure 8 The anti-overturning vibration isolation building of this utility model differs from Embodiment 3 in that the pre-tightening structure of the lateral elastic support device includes a pre-tightening adjustment shim 14 and a pre-tightening shoulder 11, wherein the pre-tightening shoulder 11 is provided on the outer shell 10, and the pre-tightening adjustment shim 14 is provided between the outer shell 10 and the outer supporting building 2.
[0049] Compared to Embodiment 3, the technical solution described in this example utilizes the pre-tightening shoulder to provide space for placing the jack. After ensuring that the elastic restoring force output by the lateral elastic support device reaches its optimal state, the compression amount of the elastic element 8 in the lateral elastic support device is locked using the pre-tightening adjusting shim 14. This technical solution, with the use of the pre-tightening adjusting shim, offers more precise adjustment and is more convenient to operate. It should be noted that the technical solution described in this example does not preclude the use of pre-tightening adjusting rods and locking nuts. For example, threaded holes can be correspondingly provided on the pre-tightening shoulder of the outer shell and the inner shell. The pre-tightening adjusting rod and locking nut are then used to engage with the threaded holes to pre-tighten and compress the lateral elastic support device. After compressing the elastic element and placing the pre-tightening adjusting shim, the pre-tightening adjusting rod and locking nut can be removed.
[0050] Example 5
[0051] like Figure 9 , Figure 10The anti-overturning vibration isolation building of this utility model differs from Embodiment 1 in that the anti-overturning structure includes a three-layer horizontal elastic support group arranged vertically between the vibration isolation building body 1 and the outer supporting building 2. The outer supporting building 2 surrounds the vibration isolation building body 1. The horizontal elastic support device 6 in the horizontal elastic support group is also simultaneously arranged between the long side of the vibration isolation building body 1 and the outer supporting building 2, and between the short side of the vibration isolation building body 1 and the outer supporting building 2. In addition, the horizontal elastic support device 6 is provided with a vertical sliding friction pair with a friction coefficient of less than 0.12. The vertical sliding friction pair includes a friction plate 18 and a connecting seat 19, wherein the connecting seat 19... The inner shell 9 is fixed to the floor slab 7 by anchor bolts 20, the friction plate 18 is fixed to the connecting seat 19, the surface of the inner shell 9 is precision machined, and the inner shell 9 presses against the surface of the friction plate 18 made of polytetrafluoroethylene material, and the two are tightly fitted together; in addition, the elastic element 8 in the transverse elastic support device 6 is a rubber elastomer, and the rubber elastomer is vulcanized and fixed together with the inner shell 9 and the outer shell 10; fourth, the anti-overturning vibration isolation building described in this example also includes a pressure equalizing plate 17, which is made of steel plate and is pre-embedded and fixed in the outer supporting building 2. The pressure equalizing plate 17 is set correspondingly to the transverse elastic support device 6, and the outer shell 10 and the pressure equalizing plate 17 are fixed together by fasteners 15.
[0052] In the technical solution described in this example, because anti-overturning structures are simultaneously installed between the long and short sides of the vibration-isolated building body and the surrounding supporting structure, the swaying or swinging amplitude of the vibration-isolated building body along its long and short sides in the horizontal direction (i.e., laterally) during an earthquake can be effectively limited, thereby effectively preventing the vibration-isolated building body from overturning and further improving the stability and seismic resistance of the vibration-isolated building body. Furthermore, because the technical solution described in this example adds a sliding friction pair to the lateral elastic support device, it can effectively avoid the harmful effects of large vertical relative displacements caused by earthquakes on the lateral elastic support device. When the relative amplitude is small, the vertical deformation of the elastic elements in the lateral elastic support device adapts to the relative displacement between the vibration-isolated building body and the surrounding supporting structure during vibration. When the amplitude is large, the sliding friction between the friction plate and the inner shell in the sliding friction pair adapts to the relative displacement between the vibration isolation building body and the outer supporting building during the vibration process. At this time, the lateral elastic support device provides a vertical guiding function, ensuring that the elastic vibration isolation device can fully play its vibration isolation role. In addition, the elastic element adopts a rubber elastomer. Since the rubber elastomer can provide both elasticity and damping, the same element in this type of scheme can be used as both an elastic element and a damping element. Moreover, the rubber elastomer can also play a technical role in blocking solid-borne sound transmission. In addition, due to the addition of the equalizing plate, the lateral load reduction force of the lateral elastic support device can be evenly applied to the outer supporting building, which can effectively avoid damage caused by excessive local load.
[0053] Based on the technical principles of this example, the anti-overturning structure can also be installed only on some floors of the multi-story floor slabs within the height range of the surrounding supporting building, for example... Figure 9 In the illustrated technical solution, transverse elastic support groups can also be installed only on the floor slab closest to the ground and the lowest floor slab, without installing transverse elastic support groups on the middle floor slab, which can also achieve good results. The advantage of setting transverse elastic support groups between the floor slabs of this partially vibration-isolated building body and the outer supporting building is that it can optimize the stress on the vibration-isolated building body and the outer supporting building and can better reduce economic costs. Of course, in practical applications, the number of floor slabs of the vibration-isolated building body within the height range of the outer supporting building can also exceed three layers, such as four, five or even more layers. The above arrangement principle can also be followed when setting up the anti-overturning structure; in addition, based on Figure 10 The technical principles recorded in it, such as Figure 11 As shown, the equalizing plate 17 can also be fixedly installed on the floor slab 7 using a pre-embedded steel plate, and the friction plate 18 can be in contact with the outer shell 10 to achieve relative sliding when the amplitude exceeds the limit. The connecting seat 19 is fixed to the outer supporting building 2 by anchor bolts 20, which can also achieve the same technical effect. It should be noted that the friction plate material and equalizing plate material mentioned in this example are only to illustrate the commonly used materials for these components, and are not specific limitations on the materials. For example, the equalizing plate can also be made of stainless steel, the friction plate can also be made of copper alloy material with a low coefficient of friction, and even the friction plate can be made by electroplating or spraying a wear-resistant functional layer with a low coefficient of friction on the surface of the steel plate, which can also achieve good results. In practical applications, the choice can be made according to the engineering conditions. Similarly, the elastic element can also be made of elastic polyurethane, which also has good elastic buffer performance and damping characteristics, and can also achieve the technical effect of blocking vibration and solid sound transmission at the same time. These are all simple variations based on the technical principle of this utility model, and are all within the protection scope of this utility model.
[0054] It should be noted that when the total height of the vibration isolation building is relatively high, in order to ensure that the external supporting building can effectively limit the swaying or swinging amplitude of the vibration isolation building and play a reliable anti-overturning role, it is preferable to make horizontal shear reinforcement on the external supporting building to improve the structural strength of the external supporting building.
[0055] Example 6
[0056] like Figure 12The anti-overturning vibration isolation building of this utility model differs from Embodiment 5 in that a pressure equalizing plate 17 can be simultaneously fixed on the outer supporting building 2 and the floor slab 7. In addition, a vertical sliding friction pair with a friction coefficient of less than 0.12 is set between the transverse elastic support device and the outer supporting building 2. Specifically, the friction plate 18 is fixed on the pressure equalizing plate 17 fixed in the outer supporting building 2, and the inner shell 9 in the transverse elastic support device is fixed on the pressure equalizing plate 17 fixed in the floor slab 7 by fasteners 15. The surface of the outer shell 10 in contact with the friction plate 18 is finely finished and smooth, and the outer shell 10 and the friction plate 18 are tightly fitted to form the vertical sliding friction pair.
[0057] Compared with the technical solution described in Example 5, the sliding friction pair structure in this example is simpler and more compact, with fewer parts and less space occupied, which helps to reduce the overall cost.
[0058] Of course, based on the technical principles of this example, a vertical sliding friction pair with a friction coefficient of less than 0.12 can also be installed between the lateral elastic support device and the floor slab within the height range of the external supporting building, for example... Figure 13 As shown, the friction plate 18 is fixed on the pressure equalizing plate 17 fixedly installed in the floor slab 7. The outer shell 10 of the transverse elastic support device is fixed on the pressure equalizing plate 17 fixedly installed in the outer supporting building 2 by fasteners 15. The surface of the inner shell 9 that contacts and cooperates with the friction plate 18 is smoothly finished. The inner shell 9 and the friction plate 18 are tightly fitted to form the vertical sliding friction pair, which can also achieve the same technical effect and is also within the protection scope of this utility model.
[0059] It should be noted that, under normal circumstances, a friction coefficient of less than 0.12 is sufficient to achieve the vertical sliding function of the vertical sliding friction pair. However, in order to minimize the adverse effects on vibration isolation performance, it is preferable to select a friction pair with a friction coefficient of around 0.05. In addition, in this utility model, the equalizing plate on the floor slab and / or the external supporting building can be set one-to-one for the transverse elastic support device, or two transverse elastic support devices can share one equalizing plate (preferably, the equalizing plate is made of pre-embedded steel plate). Of course, three or even more transverse elastic support devices can share one equalizing plate, all of which can achieve the same technical effect. In engineering, the design and arrangement can be carried out according to actual needs.
[0060] Example 7
[0061] like Figure 14The anti-overturning and vibration isolation building of this utility model differs from Embodiment 6 in that the elastic element 8 in the transverse elastic support device is a helical steel spring; in addition, the transverse elastic support device is also provided with a sound-insulating elastic layer, which is disposed between the elastic element 8 and the outer shell 10. The sound-insulating elastic layer includes a sound-insulating elastic pad 21 and a connecting plate 23. The rubber sound-insulating elastic pad 21 and the steel plate connecting plate 23 are vulcanized and fixed together. The elastic element 8 is disposed between the connecting plate 23 and the inner shell 9.
[0062] In the technical solution described in this example, the lateral elastic support device uses a combination of helical steel springs and sound-insulating elastic layers. This fully leverages the advantages of helical steel springs, such as their strong load-bearing capacity, stable performance, and long service life. At the same time, the sound-insulating elastic layer blocks the transmission path of solid-borne sound through the helical steel springs, which helps to further improve the vibration reduction performance of the system.
[0063] Based on the technical principles of this example, the location and structure of the sound-insulating elastic layer can vary greatly, for example, such as... Figure 15 As shown, the sound-insulating elastic layer can also be set between the lateral elastic support device and the outer supporting building. Specifically, the sound-insulating elastic layer is set between the outer shell 10 and the equalizing plate 17. The sound-insulating elastic layer is composed of a sound-insulating elastic pad 21 made of polyurethane material. To prevent solid-borne sound from being transmitted between the outer supporting building and the lateral elastic support device via the fastener 15, a rubber elastic isolator 22 is also provided between the fastener 15 and the outer shell 10; of course, as Figure 16 As shown, the sound-insulating elastic layer can also be set between the transverse elastic support device and the floor slab 7.
