[0047] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0048] The self-resetting support device according to the embodiment of the present invention is described below with reference to the accompanying drawings.

[0049] like Figure 1-Figure 9 As shown, the self-resetting support device of the embodiment of the present invention includes a first support body 1, a second support body 2, a first end plate 3, a second end plate 4, a reset member 5 and an energy dissipation component 6.

[0050] The first support body 1 and the second support body 2 are arranged relative to each other along the first direction, and the first support body 1 and the second support body 2 can move relative to each other in the first direction. The first end plate 3 abuts against the end of the first support body 1 away from the second support body 2 and the end of the second support body 2 close to the first support body 1. The second end plate 4 abuts against the end of the second support body 2 away from the first support body 1 and the end of the first support body 1 close to the second support body 2. The first end plate 3 and the second end plate 4 are arranged parallel and relative to each other in the first direction. That is to say, Figure 1-Figure 3As shown, when the first support body 1 and the second support body 2 move away from each other in the first direction, the first end plate 3 will move synchronously with the first support body 1, and the second end plate 4 will move synchronously with the second support body 2. When the first support body 1 and the second support body 2 approach each other in the first direction, the first end plate 3 will move synchronously with the second support body 2, and the second end plate 4 will move synchronously with the first support body 1. In the above two cases, the first end plate 3 and the second end plate 4 are always away from each other.

[0051] like Fig. 9 As shown, the reset member 5 is connected between the first end plate 3 and the second end plate 4. Therefore, no matter the first support body 1 and the second support body 2 are away from or close to each other along the first direction, the reset member 5 will always be pulled by the first end plate 3 and the second end plate 4 in the first direction and stretched, thereby applying a reset force between the first end plate 3 and the second end plate 4, driving the first support body 1 and the second support body 2 to reset.

[0052] Optionally, the reset member 5 is a shape memory alloy stranded wire. Preferably, the shape memory alloy stranded wire is made of Ni-Ti shape memory alloy wire, and the specification of the shape memory alloy stranded wire is 1*7 or 7*7;

[0053] Optionally, there are multiple reset members 5, and the multiple reset members 5 are connected between the first end plate 3 and the second end plate 4. The multiple reset members 5 are evenly distributed along the circumference of the first end plate 3 and the second end plate 4, which can ensure that the first end plate 3 and the second end plate 4 are parallel, and the force between the two is always parallel to the first direction.

[0054] The two ends of the energy-absorbing component 6 in the first direction are respectively connected to the first support body 1 and the second support body 2. When the first support body 1 and the second support body 2 are not subjected to external force, the self-resetting support device is in an initial state. When the first support body 1 and the second support body 2 are subjected to external force and move relative to each other in the first direction, the energy-absorbing component 6 can offset part of the external force through its own energy consumption. When the external force disappears, under the action of the reset member 5, the self-resetting support device will restore to its initial state as much as possible.

[0055] Among them, Figure 4-Figure 6As shown, the energy dissipation assembly 6 includes a center plate 61, a clamping plate component and a connecting member 63. The center plate 61 and the clamping plate component are arranged along the first direction. The clamping plate component includes two parallel clamping plates 62. A partial section of the center plate 61 is located between the two clamping plates 62. The connecting member 63 is connected between the two clamping plates 62 so that the two clamping plates 62 clamp the center plate 61. The connected center plate 61 and the clamping plate component can move relative to each other in the first direction. Optionally, the connecting member 63 is a bolt. By adjusting the preload force applied by the connecting member 63 between the clamping plate 62 and the center plate 61, the friction force between the clamping plate 62 and the center plate 61 can be adjusted. When the force applied to the first support body 1 and the second support body 2 in the first direction is greater than the sliding force of the connected center plate 61 and the clamping plate component in the first direction, the center plate 61 and the clamping plate component can move relative to each other.

[0056] The sliding force is a force that can drive the connected center plate 61 and the clamping plate component to move from a static state to a relatively moving state in the first direction.

[0057] The first support body 1 and the second support body 2 in the embodiment of the present invention are arranged between beams, columns and other components of the building structure. When an earthquake occurs, the first support body 1 and the second support body 2 will move relative to each other as the building structure vibrates, deforms or is damaged. By adjusting the preload force applied by the connecting member 63 between the clamping plate 62 and the center plate 61, the friction energy dissipation capacity of the energy dissipation component 6 can be adjusted to meet the preset earthquake resistance level requirements. In addition, the reset member 5 can provide a reset force for the first support body 1 and the second support body 2, driving the building structure to be restored to its original state as much as possible as the first support body 1 and the second support body 2 are reset, thereby reducing or avoiding the degree of post-earthquake damage to the building structure.

[0058] The self-resetting support device of the embodiment of the present invention can adjust the energy dissipation capacity between the splint 62 and the center plate 61 by adjusting the preload force between the splint 62 and the center plate 61, has good anti-seismic effect, and can perform controllable adjustment of stiffness. The reset member 5 between the first end plate 3 and the second end plate 4 can realize the self-resetting function and reduce the residual deformation of the structure.

[0059] The energy consumption component 6 is further described below in conjunction with the accompanying drawings.

[0060] In some embodiments, at least one of the center plate 61 and the clamping plate components is multiple in number, and the center plate 61 and the clamping plate components are alternately arranged in the first direction. For example, the number of the center plate 61 is at least one, and the number of the clamping plate components is at least two, so that the adjacent center plates 61 and clamping plate components can achieve friction energy dissipation through relative movement between the two, thereby achieving dual-stage or more-stage friction energy dissipation.

[0061] Furthermore, when the energy dissipation component 6 is capable of achieving multi-stage friction energy dissipation, the preload force applied between the center plate 61 and the clamping plate component by adjusting the connecting member 63 can make the sliding force of at least one group of connected center plates 61 and clamping plate components in the first direction greater than the sliding force of other connected center plates 61 and clamping plate components in the first direction. At this time, the self-resetting support device can function in earthquakes of different magnitudes, and at the same time, the maximum displacement value between the center plate 61 and the clamping plate component at different stages can be controlled to control the displacement value of the self-resetting support device in small, medium and large earthquakes.

[0062] Specifically, connecting holes 64 are provided on the center plate 61 and the splint component, and the connecting parts 63 are provided in the corresponding connecting holes 64 between the center plate 61 and the splint component. The connecting hole 64 in at least one of the connected center plate 61 and the splint component is a long hole extending along the first direction. The length of the long hole limits the displacement range of the connected center plate 61 and the splint component, so that the displacement value of the corresponding energy consumption stage can be controlled while ensuring the effective and stable connection between the center plate 61 and the splint component.

[0063] When the displacement of the first support plate and the second support plate in the self-resetting support device is small, the center plate 61 with smaller preload and the clamping plate component first slide relative to each other. As the displacement of the first support plate and the second support plate in the self-resetting support device continues to increase, the center plate 61 with smaller preload and the clamping plate component reach the maximum displacement value, and then the center plate 61 with larger preload and the clamping plate component begin to slide relative to each other.

[0064] In order to cope with the uncertainty of earthquakes and realize an efficient earthquake-resistant system, in the case of a small earthquake, the center plate 61 and the splint component with a smaller preload force in the embodiment of the present invention first slide relative to each other. In the case of a large earthquake, after the center plate 61 and the splint component with a smaller preload force reach the maximum displacement, the center plate 61 and the splint component with a large preload force slide and provide a larger load and energy dissipation capacity. During the entire self-resetting support loading process, the reset member 5 provides a reset force to enable the energy dissipation component 6 to achieve self-reset.

[0065] Furthermore, the self-resetting support device also includes a sliding block 65, which is arranged in the elongated hole, and the sliding block 65 is movable in the elongated hole along the first direction. The sliding block 65 is provided with a through hole, and a part of the section of the connecting member 63 is penetrated in the through hole. The sliding block 65 can be filled in the elongated hole, and the sliding block 65 will move together with the connecting member 63 (high-strength bolt). The sliding block 65 abuts against the end of the elongated hole to limit the position, so as to avoid the connecting member 63 directly colliding with the side wall of the elongated hole. The sliding block 65 can play a protective role for the connecting member 63 and can increase the abutment area. When there are multiple connecting members 63 arranged between the center plate 61 and the clamping plate component, the multiple connecting members 63 are all penetrated by the same sliding block 65, so as to ensure that the multiple connecting members 63 are subjected to basically the same force, and to prevent the problem of a single connecting member 63 being broken due to excessive force.

[0066] In addition to controlling the length of the long holes in the connected center plate 61 and the clamping plate components, the displacement value of each energy consumption stage can also be changed by controlling the size of the sliding block 65 to control the displacement value of the self-resetting support device in different earthquake magnitudes.

[0067] like Figure 1 As shown, the self-resetting support device shown in the figure includes two clamping plate components and a center plate 61. The two clamping plate components are located at both ends of the center plate 61, which can realize double-stage friction energy consumption. Of course, two center plates 61 and a clamping plate component can also be arranged so that the two center plates 61 are located at both ends of the clamping plate component to realize double-stage friction energy consumption. The work of the self-resetting support device is divided into two stages: in the first stage, the center plate 61 and the clamping plate component with a smaller preload force start to work, and the center plate 61 and the clamping plate 62 realize friction energy consumption by mutual movement. This stage aims to achieve the low energy dissipation target of the damper when a small earthquake occurs. In this process, the sliding block 65 slides in the long hole. After the sliding block 65 contacts the wall surface at one end of the long hole, the work of the first stage ends. The self-resetting support device enters the second stage of work, and the center plate 61 and the clamping plate component with a larger preload force start to work. The center plate 61 and the clamping plate 62 consume energy through sliding friction. The load in the second stage is greater than the load in the first stage, and the energy consumption capacity is also greater than the energy consumption capacity in the first stage.

[0068] During the entire loading process of the self-resetting support device, the reset member 5 is always stretched regardless of the tension stage or the compression stage. Therefore, sufficient restoring force can be provided in the unloading stage to ensure the reset of the self-resetting support device.

[0069] The starting force of the energy dissipation component 6 at different stages can be adjusted by controlling the friction coefficient, preload force and the number of bolts, etc. The friction coefficient can also be controlled by changing the material of the friction plate 66 between the center plate 61 and the clamping plate 62, for example, brass plates, brake pads and fiber composite materials can be used. The starting force of different stages can be changed by changing the preload force, and the starting force of the friction device can also be adjusted by adjusting the number of bolts.

[0070] In order to ensure the working mechanism of the damper of the present invention, the starting forces of the friction energy consumption in multiple stages are different, that is, the starting force between at least partially connected center plates 61 and clamping plates 62 is different from the starting force between other partially connected center plates 61 and clamping plates 62.

[0071] In order to increase the friction energy dissipation effect between the clamping plate 62 and the center plate 61, the self-resetting support device of the embodiment of the present invention further includes a friction plate 66, which is arranged between the clamping plate 62 and the center plate 61. The friction plate 66 can be a brass plate, which has strong wear resistance, reduces the friction loss between the clamping plate 62 and the center plate 61, and ensures the stability of the friction load.

[0072] In some embodiments, Figure 7 and Figure 8 As shown, the first support body 1 includes a first side panel 11 and a first vertical panel 12, the two first side panels 11 are parallel and oppositely arranged, and the first vertical panel 12 is connected between the two first side panels 11; the second support body 2 includes a second side panel 21 and a second vertical panel 22, the two second side panels 21 are parallel and oppositely arranged, and the second vertical panel 22 is connected between the two second side panels 21. The first side panels 11 and the second side panels 21 correspond one to one and fit together in a direction perpendicular to the first direction, so as to achieve lateral limitation and prevent the first support body 1 and the second support body 2 from lateral deviation.

[0073] The structures of the first support body 1 and the second support body 2 are roughly the same, but because they need to be aligned with the first end plate 3 and the second end plate 4, the two second side plates 21 of the second support body 2 can be directly fixed to both sides of the width direction of the second vertical plate 22 by welding, and a connecting rod 14 is provided between the ends of the two first side plates 11 of the first support body 1 away from the second support body 2, and the first vertical plate 12 is also connected to the connecting rod 14. At this time, the first vertical plate 12 is located between the two first side plates 11, and there is a gap between the first side plate 11 and the first vertical plate 12, the size of the gap is not less than the thickness of the second side plate 21, so that the end of the second side plate 21 close to the first support body 1 can abut against the first end plate 3.

[0074] Further, the first vertical plate 12 has a first connection portion 13, the second vertical plate 22 has a second connection portion 23, and the two ends of the energy dissipation component 6 are respectively connected to the first connection portion 13 and the second connection portion 23. The first connection portion 13 is arranged on the section of the first vertical plate 12 between the two first side plates 11, and the second connection portion 23 is arranged on the section of the second vertical plate 22 between the two second side plates 21. The two ends of the energy dissipation component 6 can be a clamping plate component or a center plate 61. When the energy dissipation component 6 is connected to the first connection portion 13 and the second connection portion 23, it is necessary to ensure that the clamping plate 62 and the center plate 61 are parallel to the first direction. If there is a non-parallel situation, a pad 67 can be provided to ensure the stability of the assembly structure and the parallelism between the components. The first connection portion 13 and the second connection portion 23 can be ear plates, and the center plate 61 or the clamping plate 62 in the energy dissipation component 6 can be connected to the ear plate by bolts and other fixings.

[0075] One end of the first vertical plate 12 away from the second supporting body 2 and one end of the second vertical plate 22 away from the second supporting body 2 can be used to be connected to a building structure.

[0076] The self-resetting support device in the embodiment of the present invention is a shock-absorbing control device, which is mainly used as a support in a beam-column frame. It can achieve a high level of earthquake resistance by providing different energy dissipation capabilities for earthquakes of different levels, and can continue to be put into use after an earthquake without repair or with simple repair, thereby improving the earthquake resistance cost and earthquake resistance performance of the building structure throughout its life cycle, and providing an efficient and reliable shock-absorbing solution for structural shock absorption.

[0077] The self-resetting support device of the present invention has a multi-stage working mechanism, that is, different levels of energy consumption strategies are adopted at different earthquake magnitudes to achieve multi-level earthquake-resistant fortification levels, improve earthquake resistance, and have a fortification level of "small earthquake, small energy consumption, large earthquake, large energy consumption".

[0078] In the related art, the yield bearing capacity of the buckling energy dissipation restraint support is large. Under the action of a small earthquake, the buckling restraint remains elastic and cannot provide energy dissipation capacity for the structure, which is only reflected in the action of a large earthquake. Compared with the related art, the self-resetting support device of the present invention can play a better energy dissipation role in both small and large earthquakes due to the effect of dual-stage variable stiffness.

[0079] Compared with the traditional variable stiffness damper, the self-resetting support device of the present invention can achieve the purpose of dual-stage control through simple preload control, and through the control of the SMA stranded wire, the self-resetting function of the structure can be realized to reduce the residual deformation of the structure.

[0080] The present invention mainly uses friction to dissipate energy, and all components maintain elasticity throughout the entire working process. After an earthquake, they do not need to be replaced or can resume working by simply replacing the friction plate, thereby reducing maintenance costs and post-earthquake repair costs.
