[0002] In recent years, subway becomes the preferred mode of transport for a large number of urban residents due to large capacity, fast speed and no traffic jams. Due to large passenger flow and personnel concentration, subway stations show significant commercial value, so many cities start to invest in exploring the commercial potential of subway overlying properties and have achieved obvious economic benefits. In order to further improve land intensification, subway overlying properties include a large number of high-rise buildings. In order to improve the environmental comfort of subway overlying properties and avoid the adverse effects of subway operation vibration on the personnel inside the properties, vibration isolation measures need to be taken for some sensitive subway overlying properties, such as the enhanced vibration isolation assembly disclosed in patent No. CN117005551A. However, higher vibration isolation buildings, especially high-rise vibration isolation buildings using steel spring vibration isolation, have large horizontal sway in strong wind and earthquake, which affects the comfort and safety of vibration isolation buildings in large earthquakes, and the overall height of the building structure is also greatly limited, which has a great adverse effect on economy.
[0003] In summary, there is an urgent need in the market to provide a vibration isolation building structure with higher land utilization rate, better comfort, safety and economy. SUMMARY
[0004] The present application aims to overcome the above-mentioned defects and provide an anti-overturning vibration isolation building that can effectively improve the height restriction, comfort, safety and economy.

[0013] The anti-overturning vibration isolation building of the present invention is realized by arranging a peripheral 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 up and down between the vibration isolation building body and the peripheral supporting building, which can bring the following main advantages: 1) The transverse elastic support device in the transverse elastic support group provides transverse elasticity, which can effectively avoid vibration short circuit and further improve the vibration isolation effect; 2) The transverse stiffness and damping provided by the transverse elastic support device in the transverse elastic support group can reduce the shaking or swing amplitude of the vibration isolation building body in the horizontal direction (i.e., transverse direction) when strong winds or earthquakes occur, effectively prevent the vibration isolation building body from overturning, improve the seismic resistance of the vibration isolation building body, make it safer and more reliable, and thus effectively increase the height limit of the vibration isolation building; 3) The transverse elastic support device in the transverse elastic support group can ensure that the vibration isolation performance of the elastic vibration isolation device is fully utilized, and at the same time, the vibration isolation building body has good seismic overturning resistance, truly realizing the vibration and vibration dual control effect.

[0032] Example 1 As shown in Figure 1 , Figure 2 and Figure 3The illustrated anti-overturning vibration isolation building of the present application comprises a vibration isolation building body 1 supported on a foundation through elastic vibration isolation devices 4, the vibration isolation building body 1 is a subway overlying property, the foundation comprises an earth foundation 3 above a tunnel (not specifically shown in the figure) and a bottom plate 5; in addition, it also comprises a peripheral support structure and an anti-overturning structure, the peripheral support structure is specifically a peripheral support building 2 fixedly connected with the earth foundation 3, the peripheral support building 2 is correspondingly arranged outside the long side of the vibration isolation building body 1, and the peripheral support building 2 is provided with an underground fixed structure embedded in the earth foundation 3; the anti-overturning structure comprises two layers of transverse elastic support groups arranged above and below between the vibration isolation building body 1 and the peripheral support building 2, wherein the transverse elastic support group located in the lower layer is arranged between the floor slab 7 of the bottom layer of the vibration isolation building body 1 and the peripheral support building 2, and the transverse elastic support group located in the upper layer is arranged between the highest floor slab 7 of the vibration isolation building body 1 within the height range of the peripheral support building and the peripheral support building 2, the transverse elastic support group comprises a plurality of transverse elastic support devices 6 arranged in the horizontal direction, and the transverse elastic support devices are correspondingly arranged between the two long sides of the vibration isolation building body 1 and the peripheral support building 2.

[0033] It should be noted that in engineering applications, after the transverse elastic support device 6 is arranged, the anchor bolt (not specifically shown in the figure) can be installed on the floor slab 7 or / and the peripheral support building 2 to fix the transverse elastic support device 6, so as to prevent the transverse elastic support device 6 from accidentally slipping off; of course, other convex-concave structures can also be arranged on the floor slab or the peripheral support building to limit the transverse elastic support device, these are some common measures in engineering, which are only described in words here and no additional drawings are provided.
[0034] Compared with the prior art, the anti-overturning vibration isolation building of the present application can bring the following main advantages: 1) by utilizing the elastic deformation capability of the elastic element in the lateral elastic support device in the vertical direction of the vibration isolation building body, the elastic vibration isolation device can ensure normal vibration isolation effect on the vibration isolation building body, and by utilizing the lateral elasticity provided by the lateral elastic support device in the lateral elastic support group, the vibration short circuit can be effectively avoided, and the vibration isolation effect of the elastic vibration isolation device on the vibration isolation building body is further improved; 2) by utilizing the lateral stiffness provided by the lateral elastic support device in the lateral elastic support group, the lateral elastic support device can effectively limit the swing or swing amplitude of the vibration isolation building body in the horizontal direction (i.e. lateral direction) along the short side of the vibration isolation building body during strong wind or earthquake, improve the comfort of the vibration isolation building, effectively prevent the vibration isolation building body from overturning, improve the stability and seismic resistance of the vibration isolation building body, and be more safe and reliable, so as to effectively improve 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, and the vibration isolation building body has good anti-seismic overturning capability, and truly realizes the vibration and seismic double control effect.
[0035] It should be pointed out that the lateral and vertical directions in the present application are for the vibration isolation building body, wherein the vertical direction corresponds to the vertical direction of the vibration isolation building body, and the lateral direction corresponds to the horizontal direction of the vibration isolation building body. In addition, in this example, the vibration isolation building body is taken as a subway overlying property, and in practice, the vibration isolation building body can also be other building structures which are not convenient to set underground fixed structures and use vibration isolation technology, and also within the protection scope of the present application.
[0036] In summary, the anti-overturning vibration isolation building of the present application can greatly improve the safety and reliability of the vibration isolation building body during an earthquake, has good vibration and seismic double control performance, has simple structure, good economy, high cost performance, safety and reliability, and can be widely applied to various vibration isolation building projects with peripheral support structures.
[0037] It should be noted that in the present application, the elastic element in the transverse elastic support device can be a coil spring, a disc spring, a leaf spring, rubber, an elastomer, or a polyurethane elastomer, and good technical effects can be achieved. In practice, the selection and use can be made according to the engineering needs. In addition, the peripheral support structure in this example is fixed to the ground foundation, and the peripheral support building is taken as an example for description. In actual engineering, according to the different vibration isolation building bodies, the peripheral support structure can also be a specific structure form of rock-soil or retaining wall around the vibration isolation building body, and the same technical effects can be achieved. These are simple changes based on the technical principles of the present application, and are only described in words, and are not described one by one in the drawings, and are all within the protection scope required by the present application.
[0038] Example two As Figure 4 shown, the anti-overturning vibration isolation building of the present application is different from example one in that the transverse elastic support device 6 further comprises a pre-tightening structure, which is specifically a pre-tightening adjusting gasket 14. The pre-tightening adjusting gasket 14 is made of a steel plate and is arranged between the outer shell 10 and the peripheral support building 2. The outer shell 10 and the pre-tightening adjusting gasket 14 are fixed on the peripheral support building 2 by a fastener 15.
[0039] Compared with example one, in the technical solution of the present example, the pre-tightening adjusting gasket is added, which can compensate for the size error caused during construction on the one hand, and can pre-compress the elastic element in the transverse elastic support device on the other hand. The elastic recovery force output by the transverse elastic support device acts on the vibration isolation building body, so as to ensure that the transverse elastic support device and the vibration isolation building body are always in close cooperation under normal working conditions. In addition, since the outer shell of the transverse elastic support device is fixed to the peripheral support building by the fastener, it can be ensured that the transverse elastic support device will not slip accidentally, and the structure is simple, safe and reliable.
[0040] Of course, based on the technical principles of the present example, the pre-tightening adjusting gasket can also be arranged between the inner shell and the floor, and the same technical effects can be achieved. Here, only the description is given in words, and no additional drawings are provided, and it is also within the protection scope required by the present application.
[0041] Example three As Figure 5 and Figure 6The anti-overturning vibration isolation building shown in the application is different from the second embodiment in that the peripheral support building 2 is arranged around the vibration isolation building body 1, and the anti-overturning structure is arranged between the long side and the short side of the vibration isolation building body 1 and the peripheral support building 2. The transverse elastic support device 6 in the transverse elastic support group is also arranged between the long side and the short side of the vibration isolation building body 1 and the peripheral support building 2. In addition, the transverse elastic support device 6 also includes a pre-tightening structure, which includes a pre-tightening shoulder 11 arranged on the inner housing 9 and the outer housing 10, and a pre-tightening adjusting rod 13 and a locking nut 12 arranged on the pre-tightening shoulder 11. In addition, the transverse elastic support device 6 is also provided with a damping element 16, wherein the damping element 16 is a small hole throttling damper.
[0042] Compared with the first embodiment, in the technical solution of the present embodiment, the anti-overturning structure is arranged between the long side and the short side of the vibration isolation building body and the peripheral support building, so that the shaking or swinging amplitude of the vibration isolation building body in the horizontal direction (i.e. transverse direction) along its long side and short side can be effectively limited when strong wind or earthquake occurs, thereby effectively preventing the vibration isolation building body from overturning, and being conducive to further improving the stability and wind and earthquake resistance of the vibration isolation building body. Since the damping element is added to the transverse elastic support device, the transverse elastic support device can not only provide transverse stiffness but also provide damping, so the energy dissipation capacity of the transverse elastic support device is stronger, which can better isolate vibration and effectively dissipate the external impact energy transmitted by the peripheral support building, thereby greatly reducing the impact on the vibration isolation building body, and being more safe and reliable. In addition, the pre-tightening adjusting rod 13, the locking nut 12 and the pre-tightening shoulder 11 are fixedly connected by cooperation, which can facilitate the use and transportation of the transverse elastic support device 6. In engineering application, after the transverse elastic support device 6 is arranged, the locking nut 12 can be loosened, so that the transverse elastic support device 6 is in a free working state. The pre-tightening adjusting rod 13 and the locking nut 12 are reserved, on the one hand, when the transverse elastic support device 6 needs to be taken out, the locking nut 12 can be tightened again to compress the transverse elastic support device 6, so that the housing of the transverse elastic support device 6 is separated from the floor and the peripheral support building, facilitating the operation of taking out, repairing, replacing and the like of the transverse elastic support device 6, on the other hand, when extreme conditions such as earthquake occur, the relative position of the peripheral support building and the floor changes, the elastic element 8 in the transverse elastic support device 6 can automatically rebound to compensate for the change in the distance, and due to the existence of the pre-tightening adjusting rod 13 and the locking nut 12, the distance change range between the inner housing and the outer housing can be controlled, avoiding the problem that the elastic element is tilted and falls off due to too large distance change, and being more safe and reliable.
[0043] Of course, based on the technical principle of the present embodiment, the pre-tightening shoulder can also be arranged on the inner housing or the outer housing, for example, as shown inFigure 7 As shown in the figure, only the outer shell 10 is provided with a pre-tightening shoulder 11, and the inner shell 9, the outer shell 10 and the floor 7 are fixed together by the pre-tightening adjustment rod 13 composed of fasteners and the pre-tightening shoulder 11. After the elastic element is pre-tightened and compressed into place, the inner shell 9 and the floor 7 are locked together by the locking nut 12, which can also achieve a good technical effect; in addition, in addition to using a small-hole throttling damper, the damping element can also use other forms of damping structures such as eddy current dampers, viscous dampers, viscoelastic dampers or friction dampers, which can also achieve good effects. In practice, it can be selected as needed. It is only explained in text here without additional drawings. These are simple changes based on the technical principles of the present invention and are all within the scope of protection required by the present invention.
[0044] Example 4 like Figure 8 The anti-overturning vibration isolation building of the present invention shown is different from the third embodiment in that the pre-tightening structure of the lateral elastic support device includes a pre-tightening adjustment gasket 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 gasket 14 is provided between the outer shell 10 and the peripheral supporting building 2.
[0045] Compared with the third embodiment, in the technical solution described in this example, the pre-tightening shoulder can be used to provide space for placing the jack, ensuring that the elastic restoring force output by the transverse elastic support device reaches the optimal state, and then the pre-tightening adjustment gasket 14 is used to lock the compression of the elastic element 8 in the transverse elastic support device. This technical solution uses the pre-tightening adjustment gasket for more precise adjustment and more convenient operation. It should be pointed out that the technical solution described in this example does not exclude the use of pre-tightening adjustment rods and locking nuts. For example, threaded holes can be provided on the pre-tightening shoulder of the outer shell and the inner shell respectively, and then the pre-tightening adjustment rod and the locking nut can be used in conjunction with the threaded holes to perform pre-tightening compression on the transverse elastic support device. After the elastic element is compressed and the pre-tightening adjustment gasket is placed, the pre-tightening adjustment rod and the locking nut can be removed.
[0046] Example 5 like Figure 9 、 Figure 10The anti-overturning vibration isolation building shown in the application is different from the first embodiment in that the anti-overturning structure comprises three layers of transverse elastic support groups arranged between the vibration isolation building body 1 and the peripheral support building 2, the peripheral support building 2 is arranged around the vibration isolation building body 1, and the transverse elastic support devices 6 in the transverse elastic support groups are also arranged between the long side of the vibration isolation building body 1 and the peripheral support building 2 and between the short side of the vibration isolation building body 1 and the peripheral support building 2 at the same time; in addition, the transverse elastic support device 6 is provided with a vertical sliding friction pair with a friction coefficient less than 0.12, the vertical sliding friction pair comprises a friction plate 18 and a connecting seat 19, wherein the connecting seat 19 is fixed on the floor 7 by anchor bolts 20, the friction plate 18 is fixed on the connecting seat 19, the surface of the inner housing 9 is finished, the inner housing 9 is pressed against the surface of the friction plate 18 made of polytetrafluoroethylene material, and the two are tightly attached; 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 with the inner housing 9 and the outer housing 10 to form an integral whole; fourthly, the anti-overturning vibration isolation building in the example also comprises an equalizing plate 17, the equalizing plate 17 made of steel plate is embedded and fixed in the peripheral support building 2, the equalizing plate 17 is arranged corresponding to the transverse elastic support device 6, and the outer housing 10 and the equalizing plate 17 are fixed together by fasteners 15.
[0047] In the technical solution of the example, because the anti-overturning structure is arranged between the long side and the short side of the vibration isolation building body and the peripheral support building at the same time, the shaking or swinging amplitude of the vibration isolation building body in the horizontal direction (i.e. transverse direction) along the long side and the short side can be effectively limited when an earthquake occurs, thereby effectively preventing the vibration isolation building body from overturning, and being conducive to further improving the stability and anti-seismic ability of the vibration isolation building body; in addition, because the sliding friction pair is additionally arranged in the transverse elastic support device, the harmful effect of the relatively large vertical relative displacement generated by an earthquake on the transverse elastic support device can be effectively avoided, when the relative amplitude is small, the vertical deformation of the elastic element in the transverse elastic support device is used to adapt to the relative displacement between the vibration isolation building body and the peripheral support building during vibration, and when the amplitude is large, the sliding between the friction plate and the inner housing in the sliding friction pair is used to adapt to the relative displacement between the vibration isolation building body and the peripheral support building during vibration, at this time, the transverse elastic support device provides a vertical guiding function, ensuring that the elastic vibration isolation device can fully play a vibration isolation role; in addition, the elastic element adopts a rubber elastomer, because the rubber elastomer can provide elasticity and damping, therefore the same element in this scheme can be used as an elastic element and as a damping element, and the rubber elastomer can also play a technical effect of blocking sound transmission through solid; in addition, because the equalizing plate is additionally arranged, the transverse load reduction force of the transverse elastic support device can be uniformly applied to the peripheral support building, and damage caused by local overloading can be effectively avoided.
[0048] Based on the technical principle of the example, the vibration isolation building body located in the height range of the outer supporting building can also be provided with the anti-overturning structure only at part of the floor slabs, for example Figure 9 In the technical solution shown, the transverse elastic support groups can also be respectively provided only at the floor slab close to the ground and the lowermost floor slab, and not provided at the middle floor slab, which can also achieve good results. The advantage of providing the transverse elastic support groups between the floor slabs of the vibration isolation building body and the outer supporting building is that the stress of the vibration isolation building body and the outer supporting building can be optimized, and the economic cost can be reduced better. Of course, in actual application, the number of floor slabs of the vibration isolation building body located in the height range of the outer supporting building can also be more than three, for example, four, five or even more, and the anti-overturning structure can also be arranged according to the above arrangement principle. In addition, based on the technical principle described in Figure 10 Figure 11 In the technical solution shown, the equalizing plate 17 can also be fixed on the floor slab 7 by using a pre-embedded steel plate, the friction plate 18 is in contact with the outer shell 10 and can slide relatively when the amplitude exceeds the limit, and the connecting seat 19 is fixed on the outer supporting building 2 by the anchor bolt 20, which can also achieve the same technical effect. It should be particularly noted that the materials of the friction plate and the equalizing plate in the example are only used to illustrate the commonly used materials of these components, and are not a special limitation on the materials. For example, the equalizing plate can also be made of stainless steel or other materials, the friction plate can also be made of copper alloy material with low friction coefficient, or the friction plate can also be made of steel plate with a wear-resistant functional layer with low friction coefficient by electroplating or spraying, which can all achieve good results. In actual application, the selection can be made according to the engineering conditions. Similarly, the elastic element can also be made of elastic polyurethane, which also has good elastic buffering performance and damping characteristics, and can also achieve the technical effects of blocking vibration and solid sound transmission. These are simple changes based on the technical principle of the application, and are within the protection scope of the application.
[0049] It should be particularly noted that when the total height of the vibration isolation building body is high, in order to ensure that the outer supporting building can effectively limit the swing or swing amplitude of the vibration isolation building body and play a reliable anti-overturning role, preferably, the outer supporting building needs to be designed for horizontal shear strengthening to improve the structural strength of the outer supporting building.
[0050] Example six As shown in Figure 12 The anti-overturning vibration isolation building shown in the present application is different from example five in that the equalizing plates 17 are fixed on the peripheral support building 2 and the floor 7 correspondingly and simultaneously; in addition, a vertical sliding friction pair with a friction coefficient less than 0.12 is arranged between the lateral elastic support device and the peripheral support building 2, specifically, the friction plate 18 is fixed on the equalizing plate 17 fixed in the peripheral support building 2, the inner housing 9 in the lateral elastic support device is fixed on the equalizing plate 17 fixed in the floor 7 through the fastener 15, the surface of the outer housing 10 in contact with the friction plate 18 is finely finished smooth, and the outer housing 10 and the friction plate 18 are tightly fitted to form the vertical sliding friction pair.
[0051] Compared with the technical solution of example five, the sliding friction pair structure in the technical solution of the present example is more simple and compact, the total number of parts is less, and the occupied space is also less, which is beneficial to reduce the overall cost.
[0052] Of course, based on the technical principle of the present example, a vertical sliding friction pair with a friction coefficient less than 0.12 can also be arranged between the lateral elastic support device and the floor within the height range of the peripheral support building, for example Figure 13 In the present example, the friction plate 18 is fixed on the equalizing plate 17 fixed in the floor 7, the outer housing 10 in the lateral elastic support device is fixed on the equalizing plate 17 fixed in the peripheral support building 2 through the fastener 15, the surface of the inner housing 9 in contact with the friction plate 18 is finely finished smooth, and the inner housing 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 the present application.
[0053] It should be pointed out that in general, the vertical sliding friction pair with a friction coefficient less than 0.12 can realize the vertical sliding function, but in order to reduce the adverse effect on the vibration isolation performance as much as possible, it is preferred to select a friction pair with a friction coefficient of about 0.05; in addition, in the present application, the equalizing plate on the floor and / or the peripheral support building can be arranged one-to-one for the lateral elastic support device, or two lateral elastic support devices can share one equalizing plate (preferably, the equalizing plate is made of a pre-embedded steel plate), of course, three or even more lateral elastic support devices can also share one equalizing plate, which can also achieve the same technical effect, and in engineering, it can be designed and arranged according to actual needs.
[0054] Example seven As Figure 14The anti-overturning vibration isolation building shown in the application is different from example six in that the elastic element 8 in the lateral elastic support device is a spiral steel spring; in addition, a sound insulation elastic layer is also arranged in the lateral elastic support device, the sound insulation elastic layer is arranged between the elastic element 8 and the outer shell 10, the sound insulation elastic layer comprises a sound insulation elastic pad 21 and a connecting plate 23, the sound insulation elastic pad 21 made of rubber is vulcanized and fixedly connected with the connecting plate 23 made of steel plate, and the elastic element 8 is arranged between the connecting plate 23 and the inner shell 9.
[0055] In the technical solution of the example, the spiral steel spring and the sound insulation elastic layer are used in cooperation in the lateral elastic support device, the advantages of the spiral steel spring such as strong load bearing capacity, stable performance and long service life can be fully played, and the transmission path of the solid sound through the spiral steel spring is blocked by the sound insulation elastic layer, which is beneficial to further improve the vibration reduction performance of the system.
[0056] Based on the technical principle of the example, the position and structure of the sound insulation elastic layer can be various, for example, as shown in Figure 15 The sound insulation elastic layer can also be arranged between the lateral elastic support device and the peripheral support building, specifically, the sound insulation elastic layer is arranged between the outer shell 10 and the pressure equalizing plate 17, the sound insulation elastic layer is composed of a sound insulation elastic pad 21 made of polyurethane material, and in order to prevent the solid sound from being transmitted between the peripheral support building and the lateral elastic support device through the fastener 15, an elastic isolator 22 made of rubber is arranged between the fastener 15 and the outer shell 10; of course, as shown in Figure 16 The sound insulation elastic layer can also be arranged between the lateral elastic support device and the floor 7, specifically, the sound insulation elastic layer is arranged between the inner shell 9 and the pressure equalizing plate 17, the sound insulation elastic layer is composed of a sound insulation elastic pad 21 made of rubber material, and an elastic isolator 22 made of rubber is arranged between the fastener 15 and the inner shell 9, the structure of the sound insulation elastic layer in such a technical solution is more simple and compact, and a good sound insulation effect can also be achieved, all of which are within the protection scope of the application.
