Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shock isolation, in particular to a tensile shock isolation device. BACKGROUND

[0002] Among many shock absorption systems, the shock isolation system is widely used in building engineering. The shock isolation device as an important component should have the following characteristics: load bearing capacity characteristics, restoring force characteristics, shock isolation characteristics, and energy dissipation characteristics. That is, during normal use, the shock isolation device should have sufficient vertical load bearing capacity to support the load transmitted from the upper structure to ensure that the building meets its basic requirements during construction and normal use. Under the action of horizontal earthquake, the shock isolation device needs to have sufficient restoring force to restore its original shape after horizontal deformation, and should also have sufficient horizontal stiffness to ensure that the shock isolation structure does not deform significantly under the action of small horizontal force (such as microseismic, wind load, and other external vibrations), and can play a shock isolation role under the action of medium or large earthquakes.

[0003] In order to reduce the seismic force on the upper structure, a shock isolation structure is usually arranged between the upper structure and the lower structure to reduce the seismic force on the upper structure by using the shock isolation structure. The shock isolation structure generally includes a rubber shock isolation support and a tensile structure arranged around the rubber shock isolation support. The tensile structure resists the tensile action during the vibration to prevent the rubber shock isolation support from being torn and damaged by the tensile action. However, the tensile structure in the prior art is generally fixedly arranged around the rubber shock isolation support, and cannot be flexibly adjusted in position, so that the tensile structure cannot produce good tensile effect in any direction, which reduces the use effect of the tensile structure.

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0047] Please refer to Figure 1As shown, the anti-tension isolation device in the embodiment of the present application comprises: oppositely arranged first and second connecting structures 1 and 2; an elastic support structure 3 arranged between the first and second connecting structures 1 and 2; and an adaptive anti-tension mechanism 4 comprising a first sliding structure 41, a second sliding structure 42, and a plurality of anti-tension connecting pieces 43, the first sliding structure 41 being arranged on the first connecting structure 1 in a circumferential ring along the elastic support structure 3, the second sliding structure 42 being arranged on the second connecting structure 2 in a circumferential ring along the elastic support structure 3, and the plurality of anti-tension connecting pieces 43 being slidably arranged between the first and second sliding structures 41 and 42.

[0048] Overall, when the anti-tension isolation device is in use, the first and second connecting structures 1 and 2 can be connected to the upper structure 100 and the lower structure 200, respectively, and the elastic support structure 3 is arranged between the first and second connecting structures 1 and 2. Under the action of vibration, the elastic support structure 3 can deform to buffer the vibration. After the vibration stops, the elastic support structure 3 can automatically restore its original shape.

[0049] Further, in order to prevent the elastic support structure 3 from being stretched and torn by the vibration, the adaptive anti-tension mechanism 4 is arranged between the first and second connecting structures 1 and 2. The adaptive anti-tension mechanism 4 can be adaptively adjusted under the action of vibration, thereby better resisting the stretching damage force of the vibration and avoiding the elastic support structure 3 from being stretched and torn by the vibration.

[0050] Specifically, the first sliding structure 41 is arranged on the first connecting structure 1, the second sliding structure 42 is arranged on the second connecting structure 2, and the plurality of anti-tension connecting pieces 43 can slide between the first and second sliding structures 41 and 42. As shown in Figure 7 、 Figure 8 and Figure 9 When the vibration acts, the vibration displacement will occur between the upper structure 100 and the lower structure 200. At this time, the plurality of anti-tension connecting pieces 43 will automatically adjust the anti-tension position under the action of the vibration displacement, and then re-distribute the anti-tension connecting pieces 43 on the longitudinal separation position between the upper structure 100 and the lower structure 200, so that the plurality of anti-tension connecting pieces 43 can resist the stretching force of the upper structure 100 and the lower structure 200 on the elastic support structure 3, and avoid the elastic support structure 3 from being stretched and torn.

[0051] The upper structure 100 and the lower structure 200 can be a column structure, a plate structure, a beam structure, or a frame structure, and the specific structure of the upper structure 100 and the lower structure 200 can be determined according to the needs of use, which is not specifically limited here.

[0052] In an embodiment, the upper structure 100 is a upper column, the lower structure 200 is a lower column, and the tensile isolation device is arranged between the upper column and the lower column to serve as an isolation device.

[0053] In an embodiment of the present application, as shown in the embodiment of Figure 4 and Figure 5 the tensile isolation device further comprises a plurality of elastic return members 5 arranged in the first sliding structure 41 and / or the second sliding structure 42, each elastic return member 5 being arranged between adjacent tensile connectors 43.

[0054] By arranging the elastic return members 5 between the adjacent tensile connectors 43, the elastic return members 5 can push the adjacent tensile connectors 43 apart, so that the adjacent tensile connectors 43 slide in opposite directions, preventing each tensile connector 43 from sliding to the same position during movement, thereby avoiding eccentric tension of the tensile isolation device and improving the tensile effect.

[0055] In a specific embodiment, a plurality of elastic return members 5 are arranged in the first sliding structure 41 and the second sliding structure 42. For example, when two tensile connectors 43 are arranged between the first sliding structure 41 and the second sliding structure 42, two elastic return members 5 are arranged in the first sliding structure 41 and two elastic return members 5 are arranged in the second sliding structure 42, so that the elastic return members 5 can provide elastic resistance between the adjacent tensile connectors 43, thereby preventing the two tensile connectors 43 from sliding to the same position.

[0056] In other embodiments, the designer can adjust the number of tensile connectors 43 between the first sliding structure 41 and the second sliding structure 42 according to the needs of use, such as 3, 4 or more, which is not specifically limited herein.

[0057] In an embodiment of the present application, the elastic return member 5 comprises a flexible spring 51, which is slidably arranged in the first sliding structure 41 and / or the second sliding structure 42 and connected to the adjacent tensile connector 43.

[0058] By arranging the flexible spring 51 between the adjacent tensile connectors 43, the flexible spring 51 can push the adjacent tensile connectors 43 apart, thereby preventing each tensile connector 43 from sliding to the same position. The flexible spring 51 has a larger adjustment range, does not hinder the sliding of the tensile connector 43, and is also easy to slide in the first sliding structure 41 and the second sliding structure 42, having better adjustment flexibility.

[0059] In an embodiment of the present application, as shown in the embodiment of Figure 2The first sliding structure 41 includes a first sliding rail 411 and a first sliding groove 412 arranged on the upper end surface of the first sliding rail 411. The bottom of the first sliding groove 412 is provided with a first annular channel 413 penetrating through the first sliding rail 411. One end of the tensile connecting member 43 is arranged in the first sliding groove 412 through the first annular channel 413.

[0060] As shown in the embodiment, Figure 3 The second sliding structure 42 includes a second sliding rail 421 and a second sliding groove 422 arranged on the lower end surface of the second sliding rail 421. The bottom of the second sliding groove 422 is provided with a second annular channel 423 penetrating through the second sliding rail 421. The other end of the tensile connecting member 43 is arranged in the second sliding groove 422 through the second annular channel 423.

[0061] Specifically, as shown in the embodiment, Figure 5 The first sliding rail 411 is arranged along the circumference of the elastic support structure 3, so that the first sliding groove 412 is arranged along the axis of the elastic support structure 3 in the static state. In addition, the second sliding rail 421 is also arranged along the circumference of the elastic support structure 3, so that the second sliding groove 422 is also arranged along the axis of the elastic support structure 3 in the static state.

[0062] By arranging the two ends of the tensile connecting member 43 in the first sliding rail 411 and the second sliding rail 421 respectively, each tensile connecting member 43 can be infinitely adjusted along the circumference of the elastic support structure 3, and has better adjustment flexibility.

[0063] For example, when the upper structure 100 and the lower structure 200 are arranged in the vertical direction, if the lower structure 200 is affected by horizontal vibration, the elastic support structure 3 can deform in the horizontal direction to play a role of shock isolation between the upper structure 100 and the lower structure 200.

[0064] As shown in the embodiment, Figure 6 The tensile connecting member 43 has a small deformation amount in the vertical direction. During the process of separating the upper structure 100 and the lower structure 200 in the horizontal direction, the elastic support structure 3 will deform horizontally. At this time, the tensile connecting member 43 can spontaneously and infinitely slide along the first sliding groove 412 and the second sliding groove 422, so that the tensile connecting member 43 remains in the vertical state between the first sliding groove 412 and the second sliding groove 422, and does not affect the horizontal deformation process of the elastic support structure 3.

[0065] And, each tensile connector 43 can play a tensile role between the upper structure 100 and the lower structure 200, when the lower structure 200 is affected by vertical vibration, each tensile connector 43 can be pulled instead of the elastic support structure 3, so as to avoid tensile layered tearing damage to the elastic support structure 3 caused by vertical vibration. By setting multiple tensile connectors 43, a synergistic effect can be achieved, and the tensile performance is significantly enhanced.

[0066] In the embodiments of the present application, as shown in the examples of Figure 2 、 Figure 3 and Figure 4 , the two ends of the tensile connector 43 are respectively provided with a first sliding block 431 and a second sliding block 432, one end of the tensile connector 43 is slidably arranged in the first sliding groove 412 through the first sliding block 431, and the other end of the tensile connector 43 is slidably arranged in the second sliding groove 422 through the second sliding block 432.

[0067] By respectively setting the first sliding block 431 and the second sliding block 432 at the two ends of the tensile connector 43, the first sliding block 431 and the second sliding block 432 can be used to limit the position, preventing the two ends of the tensile connector 43 from being separated from the first sliding groove 412 and the second sliding groove 422. And the first sliding block 431 and the first sliding groove 412, the second sliding block 432 and the second sliding groove 422 have smaller sliding friction, and have better sliding adjustment effect.

[0068] When horizontal vibration acts on the lower structure 200, the upper structure 100 and the lower structure 200 will be separated in the horizontal direction, and the upper structure 100 and the lower structure 200 will transmit horizontal tensile force to the two ends of the tensile connector 43, so that the tensile connector 43 has a tendency to tilt.

[0069] When the horizontal component force acting on the tensile connector 43 is greater than the friction between the sliding block and the sliding groove, the sliding block will slide along the sliding groove under the driving of the component force, so that the tensile connector 43 always maintains a vertical state. When the tensile connector 43 is in a vertical state, it can be considered that the tensile connector 43 is not pulled, and will not affect the normal use of the elastic support structure 3.

[0070] When vertical vibration acts on the lower structure 200, it will cause the upper structure 100 and the lower structure 200 to separate or approach along the vertical direction. When the upper structure 100 and the lower structure 200 are separated, each tensile connector 43 can be pulled instead of the elastic support structure 3, so as to avoid the elastic support structure 3 from being damaged by being pulled.

[0071] In an embodiment of the present application, the tensile connecting member 43 is a cable. The cable has a first sliding block 431 and a second sliding block 432 at two ends thereof. One end of the cable is slidably arranged in the first sliding groove 412 through the first sliding block 431, and the other end of the cable is slidably arranged in the second sliding groove 422 through the second sliding block 432.

[0072] When the cable is installed, the cable is in a taut state between the first sliding groove 412 and the second sliding groove 422, so that the cable can play a tensile effect.

[0073] In another embodiment, the tensile connecting member 43 is a tension rod. The tension rod has a first sliding block 431 and a second sliding block 432 at two ends thereof. One end of the tension rod is slidably arranged in the first sliding groove 412 through the first sliding block 431, and the other end of the tension rod is slidably arranged in the second sliding groove 422 through the second sliding block 432.

[0074] In other embodiments, the tensile connecting member 43 can be a combination of a cable and a tension rod, for example, two cables are arranged at two ends of the tension rod, or a cable is arranged between two tension rods, which is not limited specifically herein.

[0075] In the embodiment of the present application, the first sliding structure 41 further comprises a first cover body 414 covering the first sliding rail 411, and the first sliding block 431 is arranged in the first cover body 414; the second sliding structure 42 further comprises a second cover body 424 arranged on the second sliding rail 421, and the second sliding block 432 is arranged in the second cover body 424.

[0076] By covering the first sliding rail 411 with the first cover body 414, foreign matter can be prevented from entering the first sliding groove 412, thereby improving the stability of the first sliding groove 412 and the first sliding block 431. Similarly, by arranging the second cover body 424 on the second sliding rail 421, the stability of the second sliding groove 422 and the second sliding block 432 is improved.

[0077] Furthermore, by covering the first sliding rail 411 with the first cover body 414 and covering the second sliding rail 421 with the second cover body 424, the first sliding rail 411 can be easily embedded in the upper structure 100, and the second sliding rail 421 can be easily embedded in the lower structure 200, thereby having better installation stability.

[0078] In the embodiment of the present application, the first sliding groove 412 has an arc-shaped cross section, and the first sliding block 431 has a spherical shape; the second sliding groove 422 has an arc-shaped cross section, and the second sliding block 432 has a spherical shape.

[0079] By setting the first slider 431 and the second slider 432 as spherical shapes and setting the cross sections of the first sliding groove 412 and the second sliding groove 422 as arc shapes, the contact areas of the first slider 431 and the first sliding groove 412 and the contact areas of the second slider 432 and the second sliding groove 422 can be reduced, and the frictional forces between the first slider 431 and the first sliding groove 412 and between the second slider 432 and the second sliding groove 422 can be reduced.

[0080] In other embodiments, the specific structures of the sliders and the sliding grooves can be adjusted according to the needs of use, which are not specifically limited herein.

[0081] In the embodiments of the present application, the first connecting structure 1 comprises a first embedded plate 11 connected to the upper structure 100, and the second connecting structure 2 comprises a second embedded plate 21 connected to the lower structure 200.

[0082] In a specific embodiment, the upper structure 100 is set as an upper column pier, and the lower structure 200 is set as a lower column pier. The first embedded plate 11 comprises an upper connecting plate and an upper side plate arranged at the side edge of the upper connecting plate, and the upper connecting plate and the upper side plate are clamped to form a first clamping groove, so that the first embedded plate 11 can be more firmly connected to the upper structure 100 by the first clamping groove.

[0083] The second embedded plate 21 comprises a lower connecting plate and a lower side plate arranged at the side edge of the lower connecting plate, and the lower connecting plate and the lower side plate are clamped to form a second clamping groove, so that the second embedded plate 21 can be more firmly connected to the lower structure 200 by the second clamping groove.

[0084] In the embodiments of the present application, the first sliding structure 41 is embedded in the upper structure 100 and connected to the first embedded plate 11, one end of the tensile connecting piece 43 can pass through the first embedded plate 11 and be slidably connected to the first sliding structure 41; the second sliding structure 42 is embedded in the lower structure 200 and connected to the second embedded plate 21, the other end of the tensile connecting piece 43 can pass through the second embedded plate 21 and be slidably connected to the second sliding structure 42.

[0085] By embedding the first sliding structure 41 in the upper structure 100, the first sliding structure 41 can move synchronously with the upper structure 100, and has better structural stability.

[0086] Similarly, by embedding the second sliding structure 42 in the lower structure 200, the second sliding structure 42 can move synchronously with the lower structure 200, and has better structural stability. Moreover, during the synchronous movement of the second sliding structure 42 and the lower structure 200, the second sliding structure 42 can more accurately transmit the vertical tensile force on the lower structure 200 to the tensile connecting piece 43.

[0087] Further, after the first sliding structure 41 is embedded in the upper structure 100, the upper structure 100 can form horizontal limiting for the side of the first sliding structure 41 and axial limiting for the upper end of the first sliding structure 41. Moreover, the bottom of the first sliding structure 41 can be overlapped with the first embedded plate 11, and the first embedded plate 11 can perform axial limiting for the lower end of the first sliding structure 41.

[0088] Similarly, after the second sliding structure 42 is embedded in the lower structure 200, the lower structure 200 can form horizontal limiting for the side of the second sliding structure 42 and axial limiting for the lower end of the second sliding structure 42. Moreover, the top of the second sliding structure 42 can be overlapped with the second embedded plate 21, and the second embedded plate 21 can perform axial limiting for the upper end of the second sliding structure 42.

[0089] In the embodiment of the present application, the elastic support structure 3 comprises a rubber support 31 arranged between the first connecting structure 1 and the second connecting structure 2.

[0090] The rubber support 31 has good horizontal deformation performance, and by arranging the rubber support 31 between the first connecting structure 1 and the second connecting structure 2, good shock isolation can be achieved, and the upper structure 100 and the lower structure 200 can be effectively prevented from being damaged by horizontal vibration, thereby improving the anti-seismic performance between the upper structure 100 and the lower structure 200.

[0091] In a specific embodiment, one rubber support 31 is arranged between the upper structure 100 and the lower structure 200. The designer can adjust the size of the rubber support 31 according to the need for shock isolation, which is not specifically limited here.

[0092] In other embodiments, a plurality of rubber supports 31 can be arranged between the upper structure 100 and the lower structure 200, and the plurality of rubber supports 31 can be cooperatively used for shock isolation. The designer can adjust the number and position of the rubber supports 31 according to the need for use, which is not specifically limited here.

[0093] In the embodiment of the present application, the rubber support 31 is provided with an upper end plate 32 between the first connecting structure 1, and the rubber support 31 is provided with a lower end plate 33 between the second connecting structure 2.

[0094] Specifically, the upper end plate 32 is fixedly arranged at the top end of the rubber support 31, and the rubber support 31 is connected to the upper connecting plate of the first connecting structure 1 through the upper end plate 32. The upper end plate 32 increases the connection strength between the rubber support 31 and the first connecting structure 1.

[0095] The support lower end plate 33 is fixedly arranged at the lower end of the rubber support 31, and the rubber support 31 is connected with the lower connecting plate of the first connecting structure 1 through the support lower end plate 33. The support lower end plate 33 increases the connecting strength between the rubber support 31 and the second connecting structure 2.
