[0045] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.

[0046] The energy dissipation assembly and the self-resetting support device of the embodiments of the utility model are described below in combination with the drawings.

[0047] As Figures 1-3 shown, the energy dissipation assembly 6 of the embodiments of the utility model includes a center plate 61, a clamping plate component, and a connecting piece 63.

[0048] The number of at least one of the center plate 61 and the clamping plate component is multiple, the center plate 61 and the clamping plate component are arranged alternately in the first direction, the clamping plate component includes two clamping plates 62 arranged in parallel, and a part of the center plate 61 is located between the two clamping plates 62, and the connected center plate 61 and clamping plate component are relatively movable in the first direction. For example, the number of the center plate 61 is at least one, and the number of the clamping plate component is at least two, so that the adjacent center plate 61 and clamping plate component can realize friction energy dissipation through the relative movement therebetween.

[0049] The connecting piece 63 is connected between the two clamping plates 62 to clamp the central plate 61, and the connecting piece 63 is a bolt optionally. By adjusting the pre-tightening force applied between the clamping plate 62 and the central plate 61 by the connecting piece 63, the friction between the clamping plate 62 and the central plate 61 can be adjusted. When the force acting on the connected central plate 61 and clamping plate component in the first direction is greater than the start sliding force of the connected central plate 61 and clamping plate component in the first direction, the central plate 61 and the clamping plate component can move relatively, and the start sliding force of at least one group of connected central plate 61 and clamping plate component in the first direction is greater than that of other connected central plate 61 and clamping plate component in the first direction, so that each group of connected central plate 61 and clamping plate 62 component can form a stage of friction energy dissipation, thereby achieving two-stage or more-stage friction energy dissipation.

[0050] The start sliding force is a force that can drive the connected central plate 61 and clamping plate component to move from a static state to a relative movement state in the first direction.

[0051] Further, when the energy dissipation assembly 6 can realize multi-stage friction energy dissipation, the pre-tightening force applied between the central plate 61 and the clamping plate component by the connecting piece 63 can be adjusted to make the start sliding force of at least one group of connected central plate 61 and clamping plate component in the first direction greater than that of other connected central plate 61 and clamping plate component in the first direction, thereby playing a role in different earthquake magnitudes.

[0052] The energy dissipation assembly 6 of the embodiment of the utility model can adjust the pre-tightening force between the central plate 61 and the clamping plate component through the connecting piece 63, thereby controlling the start sliding force between different groups of connected central plate 61 and clamping plate component, realizing multi-stage energy dissipation, and meeting the fortification level requirements of multi-stage seismic resistance.

[0053] Further, the central plate 61 and the clamping plate component are each provided with a connecting hole 64, and the connecting piece 63 is arranged in the corresponding connecting hole 64 between the central plate 61 and the clamping plate component. Among the connected central plate 61 and clamping plate component, the connecting hole 64 in at least one of the two is a long slot extending in the first direction. The maximum displacement value between the central plate 61 and the clamping plate component in different stages is controlled by the size of the long slot, so as to control the displacement value of the self-resetting support device in small earthquakes, medium earthquakes and large earthquakes. The length of the long slot in the first direction limits the displacement range of the connected central plate 61 and clamping plate component, so as to ensure the effective and stable connection of the central plate 61 and the clamping plate component while controlling the displacement value of the corresponding energy dissipation stage.

[0054] When the earthquake magnitude is small, the force acting on both ends of the energy dissipation assembly 6 is small, the center plate 61 and the clamping plate component with small pre-tightening force slide first, and as the earthquake magnitude increases, the force acting on both ends of the energy dissipation assembly 6 increases, and after the center plate 61 and the clamping plate component with small pre-tightening force reach the maximum displacement value, the center plate 61 and the clamping plate component with large pre-tightening force start to slide.

[0055] In order to cope with the uncertainty of the earthquake and realize an efficient anti-seismic system, in the case of small earthquakes, the center plate 61 and the clamping plate component with small pre-tightening force slide first, and in the case of large earthquakes, after the center plate 61 and the clamping plate component with small pre-tightening force reach the maximum displacement, the center plate 61 and the clamping plate component with large pre-tightening force slide and provide large load and energy dissipation capacity.

[0056] Further, the energy dissipation assembly 6 further comprises a sliding block 65, the sliding block 65 is arranged in the long hole, the sliding block 65 is movable in the first direction in the long hole, the sliding block 65 is provided with a through hole, and part of the connecting piece 63 is arranged in the through hole.

[0057] The sliding block 65 can be filled in the long hole, the sliding block 65 moves together with the connecting piece 63 (high-strength bolt), the sliding block 65 is limited by abutting against the end of the long hole, direct collision of the connecting piece 63 with the side wall of the long hole is avoided, the sliding block 65 can play a protection role on the connecting piece 63, and the abutting area can be improved. When the connecting piece 63 arranged between the center plate 61 and the clamping plate component is multiple, the multiple connecting pieces 63 are arranged through the same sliding block 65, so that the multiple connecting pieces 63 are basically the same in stress, and the problem of fracture of a single connecting piece 63 due to excessive stress is prevented.

[0058] In addition to controlling the length of the long hole in the connected center plate 61 and clamping plate component, the displacement value of each friction energy dissipation stage can be changed by controlling the size of the sliding block 65, so as to control the displacement value of the self-resetting support device in different earthquake magnitudes.

[0059] In order to increase the friction energy dissipation effect between the clamping plate 62 and the center plate 61, the energy dissipation assembly 6 of the embodiment of the utility model further comprises a friction plate 66, and the friction plate 66 is arranged between the clamping plate 62 and the center plate 61. The friction plate 66 can be a brass plate, the brass plate has strong wear resistance, reduces the friction loss between the clamping plate 62 and the center plate 61, and guarantees the stability of the friction load.

[0060] As shown in FIG. 1, Figures 4-9 The self-resetting support device of the embodiment of the utility model comprises the energy dissipation assembly 6 of any one of the above.

[0061] Specifically, the self-resetting support device further comprises a first support body 1, a second support body 2, a first end plate 3, a second end plate 4 and a reset member 5. The first support body 1 and the second support body 2 are oppositely arranged along a first direction, and are movable relative to each other along the first direction. The first end plate 3 abuts against an end of the first support body 1 away from the second support body 2 and an end of the second support body 2 close to the first support body 1. The second end plate 4 abuts against an end of the second support body 2 away from the first support body 1 and an 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 parallelly and oppositely arranged along the first direction. That is, when the first support body 1 and the second support body 2 move away from each other along the first direction, the first end plate 3 moves synchronously with the first support body 1, and the second end plate 4 moves synchronously with the second support body 2. When the first support body 1 and the second support body 2 move towards each other along the first direction, the first end plate 3 moves synchronously with the second support body 2, and the second end plate 4 moves 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.

[0062] The reset member 5 is connected between the first end plate 3 and the second end plate 4. Therefore, no matter whether the first support body 1 and the second support body 2 move away from each other or move towards each other along the first direction, the reset member 5 is always stretched by the pulling of the first end plate 3 and the second end plate 4 along the first direction, so as to exert a reset force between the first end plate 3 and the second end plate 4, and drive the first support body 1 and the second support body 2 to reset.

[0063] Optionally, the reset member 5 is a shape memory alloy wire. Preferably, the shape memory alloy wire is twisted from a Ni-Ti shape memory alloy wire, and the specification of the shape memory alloy wire is 1*7 or 7*7.

[0064] Optionally, the reset member 5 is a plurality of reset members 5, and the plurality of reset members 5 are connected between the first end plate 3 and the second end plate 4 and are arranged along the circumference of the first end plate 3 and the second end plate 4. This can ensure that the first end plate 3 and the second end plate 4 are parallel, and the force between the first end plate 3 and the second end plate 4 is always parallel to the first direction.

[0065] The energy consumption assembly 6 is connected to the first support body 1 and the second support body 2 at both ends along the first direction. 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 along the first direction, the energy consumption assembly 6 can consume a part of the external force. When the external force disappears, the self-resetting support device will return to the initial state as much as possible under the action of the reset member 5.

[0066] The first support body 1 and the second support body 2 in the embodiment of the utility model are arranged between beams, columns and other components of a building structure, when an earthquake occurs, the first support body 1 and the second support body 2 will move relatively with the vibration, deformation or damage of the building structure, by adjusting the pre-tightening force of the connecting piece 63 applied between the clamping plate 62 and the center plate 61, the friction energy dissipation capacity of the energy dissipation assembly 6 can be adjusted, so that the preset anti-seismic level requirement is reached, in addition, the reset piece 5 can provide a reset force for the first support body 1 and the second support body 2, and drive the building structure to restore to the original state as far as possible with the reset of the first support body 1 and the second support body 2, and the post-earthquake damage degree of the building structure is reduced or avoided.

[0067] The self-resetting support device in the embodiment of the utility model can adjust the energy dissipation capacity between the clamping plate 62 and the center plate 61 by adjusting the pre-tightening force between the clamping plate 62 and the center plate 61, has good anti-seismic effect, and can be controlled and adjusted in rigidity, the reset piece 5 between the first end plate 3 and the second end plate 4 can realize the self-resetting function, and the residual deformation of the structure is reduced.

[0068] Figures 1-3 The self-resetting support device shown in the figure comprises two clamping plate components and a center plate 61, the two clamping plate components are located at two ends of the center plate 61, and can realize two-stage friction energy dissipation, of course, two center plates 61 and one clamping plate component can also be arranged, so that the two center plates 61 are located at two ends of the clamping plate component, and two-stage friction energy dissipation is realized. The work of the self-resetting support device is divided into two stages: in the first stage, the center plate 61 with smaller pre-tightening force and the clamping plate component start to work, the center plate 61 and the clamping plate 62 realize friction energy dissipation through mutual movement, this stage aims to realize the low energy dissipation target of the damper under the action of small earthquakes, 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 in the first stage is completed. The self-resetting support device enters the second stage of work, the center plate 61 with larger pre-tightening force and the clamping plate component start to work, the center plate 61 and the clamping plate 62 realize energy dissipation through sliding friction, the load in the second stage is greater than that in the first stage, and the energy dissipation capacity in the second stage is also greater than that in the first stage.

[0069] In the whole loading process, the reset piece 5 is always elongated whether in the tension stage or the compression stage, so that sufficient recovery force can be provided in the unloading stage, and the reset of the self-resetting support device is ensured.

[0070] The start-up sliding force of different stages in the energy dissipation assembly 6 can be adjusted by controlling the friction coefficient, the pre-tightening force, the number of bolts, etc., or by changing the material of the friction plate 66 between the center plate 61 and the clamping plate 62 to control the friction coefficient, such as using brass sheets, brake pads, and fiber composite materials, etc. The start-up sliding force of different stages can be changed by changing the pre-tightening force, and the start-up sliding force of the friction device can also be adjusted by adjusting the number of bolts.

[0071] In order to ensure the working mechanism of the damper of the utility model, the start-up sliding forces of the friction energy dissipation of multiple stages are different, that is, the start-up sliding force between at least part of the connected center plate 61 and the clamping plate 62 is different from the start-up sliding force between other parts of the connected center plate 61 and the clamping plate 62.

[0072] In some embodiments, the first support body 1 includes first side plates 11 and a first vertical plate 12, the two first side plates 11 are arranged in parallel and opposite to each other, and the first vertical plate 12 is connected between the two first side plates 11; the second support body 2 includes second side plates 21 and a second vertical plate 22, the two second side plates 21 are arranged in parallel and opposite to each other, and the second vertical plate 22 is connected between the two second side plates 21, the first side plates 11 and the second side plates 21 correspond one by one and are attached in the direction perpendicular to the first direction, which can realize lateral limiting and avoid lateral deviation of the first support body 1 and the second support body 2.

[0073] The structures of the first support body 1 and the second support body 2 are substantially the same, but since they need to be aligned and assembled 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 on both sides of the width direction of the second vertical plate 22 by welding, and the two first side plates 11 of the first support body 1 are provided with a connecting rod 14 between the ends away from the second support body 2, and the first vertical plate 12 is also connected with 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 size 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 connecting part 13, the second vertical plate 22 has a second connecting part 23, and the two ends of the energy dissipation component 6 are connected with the first connecting part 13 and the second connecting part 23 respectively. The first connecting part 13 is arranged on the section of the first vertical plate 12 between the two first side plates 11, and the second connecting part 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 the clamping plate part or the center plate 61, and when the energy dissipation component 6 is connected with the first connecting part 13 and the second connecting part 23, it is necessary to ensure that the clamping plate 62 and the center plate 61 are parallel to the first direction, and if there is a non-parallel condition, a pad 67 can be arranged to ensure the stability of the assembly structure and the parallelism between the components. The first connecting part 13 and the second connecting part 23 can be an ear plate, and the center plate 61 or the clamping plate 62 in the energy dissipation component 6 can be connected with the ear plate through a fixing member such as a bolt. The end of the first vertical plate 12 away from the second support body 2 and the end of the second vertical plate 22 away from the second support body 2 can be used to connect with the building structure.

[0075] The self-resetting support device in the embodiment of the utility model is a damping control device, mainly used as a support in a beam-column frame, can provide different energy dissipation capacities for different levels of earthquakes, thereby realizing efficient earthquake resistance level, and can continue to be put into use after the earthquake without repair or simple repair, improves the earthquake resistance cost and earthquake resistance performance in the whole life cycle of the building structure, and provides an efficient and reliable damping solution for structure damping.

[0076] The self-resetting support device is a multi-stage working mechanism, that is, different levels of energy dissipation strategies are adopted at different earthquake levels to realize multi-level earthquake prevention level, improve the earthquake resistance capacity, and have the earthquake prevention level of "small earthquake and small energy dissipation, large earthquake and large energy dissipation".

[0077] In the related art, the yield load of the buckling energy dissipation restraining support is large, the buckling restraint remains elastic under the action of a small earthquake, cannot provide energy dissipation capacity for the structure, and only reflects under the action of a large earthquake. Compared with the related art, the self-resetting support device can play a good energy dissipation effect under small earthquakes and large earthquakes due to the action of the two-stage variable stiffness.

[0078] Compared with the traditional variable stiffness damper, the self-resetting support device can realize the purpose of two-stage control through simple pre-tightening force control, and can realize the self-resetting function of the structure through the control of the SMA wire, and reduce the residual deformation of the structure.

[0079] The utility model mainly uses friction energy dissipation, all components remain elastic in the whole working process, do not need to be replaced after the earthquake or only need to be replaced by simple friction plate to work again, and the maintenance cost and post-earthquake repair cost are reduced.
