Description

Technical Field

[0001] The present invention relates to the technical field of structural engineering, and in particular to a multi-order buckling restrained energy dissipation support device. Background Art

[0002] Earthquakes are an unavoidable natural disaster. The casualties and economic losses caused by earthquakes are mainly due to excessive deformation or collapse of building structures. In order to control the dynamic response of building structures under earthquakes, a passive control technology that combines safety, reliability and economy has been proposed in the field of architecture. Passive control technology mainly adopts two methods: energy dissipation and shock absorption and seismic isolation. Among them, the energy dissipation and shock absorption method is to dissipate the energy introduced by the earthquake when the structure is deformed by setting energy dissipation components or devices, so as to achieve the purpose of protecting the main structure from earthquakes.

[0003] At present, the buckling restrained energy dissipation brace device is a commonly used energy dissipation and shock absorption device, which has the advantages of simple structure, good ductility and stable energy dissipation performance. The buckling restrained energy dissipation brace device is usually composed of an energy dissipation core plate and a constraint unit. When the structure is subjected to a certain external force, the load on the device is all borne by the energy dissipation core plate, and the constraint unit only constrains the compressive buckling of the energy dissipation core plate, so that the energy dissipation core plate can enter the yield state under tension and compression, thereby dissipating energy through the yielding of the energy dissipation core plate. It is suitable for both new buildings and seismic reinforcement.

[0004] However, the existing buckling restrained energy dissipation support device maintains elasticity before the energy dissipation core plate yields, and the bearing capacity is constant after the energy dissipation core plate yields, which cannot adaptively provide the required bearing capacity and energy dissipation requirements when the main structure encounters different levels of external excitation. Moreover, after the buckling restrained energy dissipation support device yields, it needs to be replaced as a whole, which is very costly. Summary of the invention

[0017] The beneficial effects brought by the multi-order buckling restrained energy dissipation support device of the present invention are:

[0018] By setting up a multi-order buckling restrained energy-absorbing support device which is mainly composed of an energy-absorbing unit, a first support, a second support and a constraint unit, when the axial loads on the first support and the second support change, causing the first support and the second support to produce relative displacement along the first direction, the load will be transferred to the first core plate through the first sliding plate and the second sliding plate, causing the first core plate to yield; since there is a gap between the two ends of the high-order core plate and the first support and the second support, the first support and the second support will not contact the high-order core plate in the initial stage of relative sliding, and the first connecting component will not contact the hole wall of the first long hole, and the second connecting component will not contact the hole wall of the second long hole, so the high-order core plate does not participate in the work in the initial stage.

[0019] The following is an example in which there are two high-order core plates with different adjustable gaps. When the yield deformation of the first core plate causes the first support and the second support to come into contact with the high-order core plate with a smaller adjustable gap, or the first connecting component connected to the high-order core plate moves with the first sliding plate to come into contact with the hole wall of the corresponding first long hole, and the second connecting component connected to the high-order core plate moves with the second sliding plate to come into contact with the hole wall of the corresponding second long hole, the high-order core plate with a smaller adjustable gap will yield, that is, at this stage, the first core plate and the high-order core plate deform together to dissipate energy.

[0020] When the yield deformation of the first core plate and the above-mentioned high-order core plate causes the first support and the second support to contact the high-order core plate with a larger adjustable gap, or the first connecting component connected to the high-order core plate moves with the first sliding plate to contact the hole wall of the corresponding first long hole, and the second connecting component connected to the high-order core plate moves with the second sliding plate to contact the hole wall of the corresponding second long hole, the high-order core plate with a larger adjustable gap will yield, that is, at this stage, the first core plate and multiple high-order core plates deform together to dissipate energy. In this way, adaptive regulation of different bearing capacities and energy dissipation performances of the energy dissipation unit is achieved, so that the multi-order buckling restrained energy dissipation support device can adaptively provide the required bearing capacity and energy dissipation requirements when the main structure encounters different levels of external excitations.

[0021] It can be seen from this that the multi-order buckling constrained energy dissipation support device can flexibly regulate the overall bearing capacity and energy dissipation capacity of the device in the initial stage by adjusting the mechanical properties of the first core plate, thereby giving it multi-order energy dissipation capacity and meeting the different bearing capacity and energy dissipation requirements of the main structure when encountering different levels of external excitations.

[0047] Please continue to refer to Figure 1 , and combined with Figures 2 to 5 In this embodiment, the constraint unit 400 may include a first sliding plate 410, a second sliding plate 420, a first connecting component 431 and a second connecting component 432. The energy consumption unit 300 includes a first core plate 310 and a plurality of high-order core plates arranged side by side with the first core plate 310. The first sliding plate 410 is fixedly connected to the first end of the first core plate 310 and the first support 100, and the second sliding plate 420 is fixedly connected to the second end of the first core plate 310 and the second support 200; the two ends of the high-order core plate are respectively spaced from the first support 100 and the second support 200 to form a space between the first support 100 and the second support 200. Adjustable gap 500, a first long hole 340 is opened at the first end of the high-order core plate, and a second long hole 350 is opened at the second end of the high-order core plate, and the first long hole 340 and the second long hole 350 both extend along the first direction; the first sliding plate 410 is opened with a first connecting hole 411 opposite to the first long hole 340, and the first connecting component 431 passes through the first connecting hole 411 and the first long hole 340, and the second sliding plate 420 is opened with a second connecting hole 421 opposite to the second long hole 350, and the second connecting component 432 passes through the second connecting hole 421 and the second long hole 350; multiple high-order core plates have at least one adjustable gap 500.

[0048] It should be noted that, in this embodiment, the “first direction” mentioned above can be Figures 1 to 3 The arrows ab in the figure indicate that the “second direction” mentioned below can be represented by Figures 1 to 3 The arrow cd in the figure indicates that the “third direction” can be represented by Figures 1 to 3 It is represented by the arrow ef in the figure.

[0049] Figure 6 This is a partial structural front view of the multi-order buckling restrained energy dissipation support device provided in this embodiment. Please continue to refer to Figure 1 and Figure 2 , and combined with Figure 6 In this embodiment, the number of high-order core plates is two, namely the second core plate 320 and the third core plate 330, wherein the adjustable gap 500 formed between the second core plate 320 and the corresponding support is different from the adjustable gap 500 formed between the third core plate 330 and the corresponding support.

[0050] Figure 7 The multi-stage buckling restrained energy dissipation support device provided in this embodiment is a partial structural front view in which only the first core plate 310 undergoes buckling deformation in the initial stage. Figure 7As shown, when the axial loads on the first support 100 and the second support 200 change, causing the first support 100 and the second support 200 to produce relative displacement along the first direction, the load will be transferred to the first core plate 310 through the first sliding plate 410 and the second sliding plate 420, causing the first core plate 310 to yield; since there is a gap between the two ends of the second core plate 320 and the third core plate 330 and the first support 100 and the second support 200, the first support 100 and the second support 200 will not contact the second core plate 320 and the third core plate 330 in the initial stage of relative sliding, and the first connecting component 431 will not contact the hole wall of the first long hole 340, and the second connecting component 432 will not contact the hole wall of the second long hole 350, so the second core plate 320 and the third core plate 330 do not participate in the work in the initial stage.

[0051] Figure 8 A partial structural front view of the multi-order buckling restrained energy dissipation support device provided in this embodiment in which the first core plate 310, the second core plate 320 and the third core plate 330 all buckle and deform in the subsequent stage. When the yielding deformation of the first core plate 310 causes the first support 100 and the second support 200 to contact the high-order core plate with a smaller adjustable gap 500, or the first connecting component 431 connected to the high-order core plate moves with the first sliding plate 410 to contact the hole wall of the corresponding first long hole 340, and the second connecting component 432 connected to the high-order core plate moves with the second sliding plate 420 to contact the hole wall of the corresponding second long hole 350, the high-order core plate with a smaller adjustable gap 500 will yield, that is, at this stage, the first core plate 310 and the high-order core plate deform together to dissipate energy.

[0052] When the yield deformation of the first core plate 310 and the above-mentioned high-order core plate causes the first support 100 and the second support 200 to contact the high-order core plate with a larger adjustable gap 500, or the first connecting component 431 connected to the high-order core plate moves with the first sliding plate 410 to contact the hole wall of the corresponding first long hole 340, and the second connecting component 432 connected to the high-order core plate moves with the second sliding plate 420 to contact the hole wall of the corresponding second long hole 350, the high-order core plate with a larger adjustable gap 500 will yield, that is, at this stage, the first core plate 310 and multiple high-order core plates deform together to dissipate energy. In this way, adaptive regulation of different bearing capacities and energy dissipation performances of the energy dissipation unit 300 is achieved, so that the multi-order buckling restrained energy dissipation support device can adaptively provide the required bearing capacity and energy dissipation requirements when the main structure encounters different levels of external excitations.

[0053] It can be seen from this that the multi-order buckling constrained energy dissipation support device can flexibly regulate the bearing capacity and energy dissipation capacity of the entire device in the initial stage by adjusting the mechanical properties of the first core plate 310, thereby giving it multi-order energy dissipation capacity and meeting the different bearing capacity and energy dissipation requirements of the main structure when encountering different levels of external excitations.

[0054] In addition, in the present application, by arranging the first core plate 310 and the higher-order core plate side by side, there is an overlapping length area between the first core plate 310 and the higher-order core plate in the first direction, so that when the multi-order buckling restrained energy dissipation support device is working, the breakage of a certain energy dissipation core plate will not cause the device as a whole to lose its energy dissipation function, thereby improving the adaptability and safety reserve of the multi-order buckling restrained energy dissipation support device of this embodiment under the action of strong earthquakes, and ensuring that the device can still work normally after the failure of a single energy dissipation core plate.

[0055] Moreover, the present application sets the first core plate 310 in parallel with the high-order core plate, which can achieve different deformations through the support effect to activate different energy-consuming core plates in sequence, thereby achieving the purpose of multi-order yielding, wherein the adjustable parameters include the strength of the energy-consuming core plate, the cross-sectional area of ​​the energy-consuming core plate, and the deformation conditions for activating the high-order core plate, etc. Compared with the prior art scheme of connecting multiple energy-consuming core plates in series, which can only adjust the strength and cross-sectional area of ​​the energy-consuming core plate, it is more convenient for structural design. In addition, this setting can also reduce the space occupied in the first direction, and is suitable for building structures with limited space.

[0056] In addition, by arranging the first core plate 310 in parallel with the higher-order core plate, the axial bearing capacity of the multi-order buckling restrained energy-absorbing support device is the sum of the bearing capacities of all core plates. Compared with the prior art scheme of connecting multiple energy-absorbing core plates in series, in which the axial bearing capacity is only the maximum bearing capacity of a single energy-absorbing core plate, the bearing capacity of this scheme can be significantly improved according to design requirements.

[0057] Fig. 9 This is an enlarged view of the local structure of the multi-order buckling restrained energy dissipation support device provided in this embodiment. Fig. 9 As shown, the adjustable gap 500 between the second core plate 320 and the first support 100 is recorded as δ1, the distance between the first connecting component 431 penetrating the first long hole 340 of the second core plate 320 and the hole wall of the first long hole 340 is recorded as δ2, the adjustable gap 500 between the third core plate 330 and the first support 100 is recorded as δ3, and the distance between the first connecting component 431 penetrating the first long hole 340 of the third core plate 330 and the hole wall of the first long hole 340 is recorded as δ4. Among them, δ1=δ2, δ3=δ4.

[0058] The above-mentioned "adjustable gap 500 formed between the second core plate 320 and the corresponding support is different from the adjustable gap 500 formed between the third core plate 330 and the corresponding support", that is: δ1≠δ3. The following is an example of δ1<δ3. At this time, the multi-order buckling restrained energy dissipation support device adopts three-stage energy dissipation to adaptively provide multiple levels of bearing capacity and energy dissipation capacity under different earthquake levels. The specific working mechanism is as follows.

[0059] Fig.10 The load-displacement relationship diagram of the multi-order buckling restrained energy dissipation support device provided in this embodiment when the adjustable gap 500 formed between the second core plate 320 and the third core plate 330 and the corresponding support is different. Fig.10 As shown, under the action of small earthquakes or wind loads: the interlayer deformation of the structure is small, the axial deformation of the support is less than 2 times of δ1, the second core plate 320 and the third core plate 330 are not in contact with the first support 100 and the second support 200, and the energy dissipation effect of the multi-order buckling restrained energy dissipation support device is only provided by the first core plate 310. At this time, the maximum bearing capacity is F1.

[0060] Under the action of moderate earthquake: the interlayer deformation of the structure is slightly increased compared with the interlayer deformation during small earthquake, the axial deformation of the support is still less than 2 times δ1, and the two ends of the second core plate 320 and the third core plate 330 are still not in contact with the first support 100 and the second support 200. The energy dissipation effect of the multi-order buckling restrained energy dissipation support device is still provided by the first core plate 310. At this time, the maximum bearing capacity is F1.

[0061] Under the action of a large earthquake: the interlayer deformation of the structure is significantly increased compared to the interlayer deformation during a moderate earthquake, the axial deformation of the support is greater than 2 times δ1 and less than 2 times δ2, and the two ends of the second core plate 320 are in contact with the first support 100 and the second support 200 respectively. The energy dissipation effect of the multi-order buckling restrained energy dissipation support device is provided jointly by the first core plate 310 and the second core plate 320. At this time, the maximum bearing capacity is F2.

[0062] Under the action of a super-large earthquake: the interlayer deformation of the structure is significantly increased compared to the interlayer deformation during a large earthquake, the axial deformation of the support is greater than 2 times δ2, and the two ends of the second core plate 320 and the third core plate 330 are respectively in contact with the first support 100 and the second support 200. The energy dissipation effect of the multi-order buckling restrained energy dissipation support device is jointly provided by the first core plate 310, the second core plate 320 and the third core plate 330. At this time, the maximum bearing capacity is F3.

[0063] It is understood that in other embodiments, the adjustable gap 500 formed between the second core plate 320 and the corresponding support may be set to be the same as the adjustable gap 500 formed between the third core plate 330 and the corresponding support. Fig. 9That is to say, δ1=δ2=δ3=δ4. At this time, the multi-order buckling restrained energy dissipation support device adopts two-stage energy dissipation to adaptively provide multi-level bearing capacity and energy dissipation capacity under different earthquake levels. The specific working mechanism is as follows.

Fig.11 As shown, under the action of small earthquakes or wind loads: the interlayer deformation of the structure is small, the axial deformation of the support is less than 2 times of δ1, the second core plate 320 and the third core plate 330 are not in contact with the first support 100 and the second support 200, and the energy dissipation effect of the multi-order buckling restrained energy dissipation support device is only provided by the first core plate 310. At this time, the maximum bearing capacity is F1.

[0065] Under the action of moderate earthquake: the interlayer deformation of the structure is slightly increased compared with the interlayer deformation during small earthquake, the axial deformation of the support is still less than 2 times δ1, and the two ends of the second core plate 320 and the third core plate 330 are still not in contact with the first support 100 and the second support 200. The energy dissipation effect of the multi-order buckling restrained energy dissipation support device is still provided by the first core plate 310. At this time, the maximum bearing capacity is F1.

[0066] Under the action of a large earthquake: the interlayer deformation of the structure is significantly increased compared to the interlayer deformation during a moderate earthquake, the axial deformation of the support is greater than 2 times of δ1, and the two ends of the second core plate 320 and the third core plate 330 are in contact with the first support 100 and the second support 200 respectively. The energy dissipation effect of the multi-order buckling restrained energy dissipation support device is provided by the first core plate 310, the second core plate 320 and the third core plate 330. At this time, the maximum bearing capacity is F2.

[0067] It can be seen that the multi-order buckling constrained energy dissipation support device can achieve a variety of staged energy dissipation characteristics by flexibly designing the lengths of the first long holes 340 and the second long holes 350 opened in the second core plate 320 and the third core plate 330, as well as the size of the adjustable gap 500 between the first support 100 and the second support 200, so as to adaptively provide variable stiffness, bearing capacity and energy dissipation capacity under different deformation levels.

[0068] Please continue to refer to Figure 2 , Figure 3 and Figure 6 In this embodiment, the second core plate 320 and the third core plate 330 are respectively arranged on both sides of the first core plate 310 along the second direction, and the first core plate 310, the second core plate 320 and the third core plate 330 are arranged side by side.

[0069] The above-mentioned arrangement of the first core plate 310, the second core plate 320 and the third core plate 330 enables the first core plate 310 that begins to bend and deform in the initial stage to be located in the middle of the energy-consuming unit 300, while the second core plate 320 and the third core plate 330 that begin to bend and deform in the subsequent stage are located on both sides. This not only effectively constrains both sides of the first core plate 310 along the second direction, but also ensures the uniformity of the energy-consuming unit 300 during the load-bearing process.

[0070] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the constraint unit 400 may also include a constraint plate arranged on the side of the energy consumption unit 300. Specifically, the lateral constraint plate 440 is provided with a first limiting groove 441 at a position adjacent to the first support 100 and the energy consumption unit 300, and is provided with a second limiting groove 442 at a position adjacent to the second support 200 and the energy consumption unit 300; the first sliding plate 410 is accommodated in the first limiting groove 441, and the second sliding plate 420 is accommodated in the second limiting groove 442; wherein, along the first direction, the sliding distance of the first sliding plate 410 in the first limiting groove 441 and the sliding distance of the second sliding plate 420 in the second limiting groove 442 are both greater than the sliding distance of the first connecting component 431 in the first long hole 340 and the sliding distance of the second connecting component 432 in the second long hole 350; the lateral constraint plate 440 and the energy consumption unit 300 are arranged along a third direction, and the third direction is perpendicular to both the first direction and the second direction.

[0071] The setting of the above-mentioned lateral constraint plate 440 can constrain the bending deformation of the energy consumption unit 300 along the third direction. Specifically, by setting a first limiting groove 441 for accommodating the first sliding plate 410 and a second limiting groove 442 for accommodating the second sliding plate 420 on the lateral constraint plate 440, it is also possible to avoid interference between the first sliding plate 410 and the second sliding plate 420 and the lateral constraint plate 440 during the bending deformation of the energy consumption unit 300. At the same time, the sliding action of the first sliding plate 410 in the first limiting groove 441 and the sliding action of the second sliding plate 420 in the second limiting groove 442 can be utilized to guide the movement process of the first sliding plate 410 and the second sliding plate 420, thereby avoiding the first sliding plate 410 and the second sliding plate 420 from moving along the second direction.

[0072] Please continue to refer to Figure 2 In this embodiment, the number of the lateral restraining plates 440 is two, and the two lateral restraining plates 440 are respectively arranged on both sides of the energy consumption unit 300 along the third direction.

[0073] By providing the lateral restraining plates 440 on both sides of the energy consuming unit 300 along the third direction, restraining effects can be formed on both sides of the energy consuming unit 300 along the third direction, and the restraining effect is good.

[0074] Please continue to refer to Figure 2 In this embodiment, the constraint unit 400 may further include a third connecting component 451 and a fourth connecting component 452. Specifically, a first safety hole 443 extending along the first direction is formed at one end of the lateral constraint plate 440, and a first support hole 111 opposite to the first safety hole 443 is formed at the first support 100. The third connecting component 451 passes through the first support hole 111 and the first safety hole 443, and along the first direction, the sliding stroke of the third connecting component 451 in the first safety hole 443 is greater than the sliding stroke of the first connecting component 431 in the first long hole 340 and the sliding stroke of the second The sliding stroke of the connecting component 432 in the second long hole 350; the other end of the lateral constraint plate 440 is provided with a second safety hole 444 extending along the first direction, and the second support 200 is provided with a second support hole 211 opposite to the second safety hole 444. The fourth connecting component 452 passes through the second support hole 211 and the second safety hole 444, and along the first direction, the sliding stroke of the fourth connecting component 452 in the second safety hole 444 is greater than the sliding stroke of the first connecting component 431 in the first long hole 340 and the sliding stroke of the second connecting component 432 in the second long hole 350.

[0075] By respectively setting a first safety hole 443 and a second safety hole 444 at both ends of the lateral constraint plate 440, and passing the third connecting component 451 connected to the first support 100 through the first safety hole 443, and passing the fourth connecting component 452 connected to the second support 200 through the second safety hole 444, when the multi-order buckling restraint energy dissipation support device utilizes the buckling deformation of the energy absorbing unit 300 to dissipate energy, when the first connecting component 431 moves to the maximum stroke in the first long hole 340 and the second connecting component 432 moves to the maximum stroke in the second long hole 350, as the energy absorbing unit 300 continues to deform, the first safety hole 443 and the second safety hole 444 can play a further limiting role to prevent the multi-order buckling restraint energy dissipation support device from supporting damage.

[0076] Please continue to refer to Figure 2In this embodiment, the first core plate 310 may include a first necking section 311 and a first connecting section 312 arranged at both ends of the first necking section 311, and the first connecting section 312 is used to connect with the first support 100 and the second support 200; the second core plate 320 may include a second necking section 321 and a second connecting section 322 arranged at both ends of the second necking section 321, and the second connecting section 322 is used to connect with the first support 100 and the second support 200; the third core plate 330 may include a third necking section 331 and a third connecting section 332 arranged at both ends of the third necking section 331, and the third connecting section 332 is used to connect with the first support 100 and the second support 200. 32 is used to connect with the first support 100 and the second support 200; wherein, a first constraint space 600 is formed between the first necked section 311 and the second necked section 321, and a second constraint space 700 is formed between the first necked section 311 and the third necked section 331; the constraint unit 400 also includes a first intermediate constraint plate 460 and a second intermediate constraint plate 470, the first intermediate constraint plate 460 is in the first constraint space 600, the second intermediate constraint plate 470 is in the second constraint space 700, and the first intermediate constraint plate 460 and the second intermediate constraint plate 470 are both fixedly connected to the lateral constraint plate 440.

[0077] By setting necking sections in the first core plate 310, the second core plate 320 and the third core plate 330, and setting a first intermediate restraint plate 460 and a second intermediate restraint plate 470 in the space between the necking sections of any two adjacent core plates, the bending deformation of the first core plate 310 on both sides along the second direction can be restrained, as well as the downward bending deformation of the second core plate 320 and the upward bending deformation of the third core plate 330 can be restrained, thereby ensuring the restraining effect on the energy consumption unit 300.

[0078] Please continue to refer to Figure 2 In this embodiment, the parts where the first necked section 311, the second necked section 321 and the third necked section 331 are connected to the corresponding connecting sections are all provided with arc chamfers. This setting can effectively alleviate the stress concentration between the necked sections and the corresponding connecting sections, so as to extend the service life of the energy consumption unit 300.

[0079] Please continue to refer to Figure 2 In this embodiment, along the first direction, the size of the first constraint space 600 is larger than the size of the first middle constraint plate 460, and the size of the second constraint space 700 is larger than the size of the second middle constraint plate 470, that is, the lengths of the first necked section 311 and the second necked section 321 are larger than the length of the first middle constraint plate 460, and the lengths of the first necked section 311 and the third necked section 331 are larger than the length of the second middle constraint plate 470. This configuration provides a space margin for the buckling deformation of the energy consumption unit 300 along the first direction.

[0080] In this embodiment, along the third direction, the size of the first middle restraining plate 460 and the second middle restraining plate 470 are 0.5-3 mm larger than the size of the energy consumption unit 300. In other words, the thickness of the first middle restraining plate 460 and the second middle restraining plate 470 is 0.5-3 mm larger than the thickness of the energy consumption unit 300.

[0081] The above arrangement allows the projection profile of the energy consumption unit 300 in the second direction to completely fall into the first intermediate restraining plate 460 and the second intermediate restraining plate 470, so that the deformation of the energy consumption unit 300 in the second direction can be effectively restrained by the first intermediate restraining plate 460 and the second intermediate restraining plate 470. By setting the thickness of the first intermediate restraining plate 460 and the second intermediate restraining plate 470 to be 0.5 to 3 mm greater than that of the energy consumption unit 300, it is not only possible to avoid the first intermediate restraining plate 460 and the second intermediate restraining plate 470 being too thin to achieve an effective restraining effect, but also to avoid the waste of materials and the overall thickness of the device due to the first intermediate restraining plate 460 and the second intermediate restraining plate 470 being too thick.

[0082] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the constraint unit 400 may also include a top constraint plate 480 and a bottom constraint plate 490. Specifically, the top constraint plate 480 and the bottom constraint plate 490 are respectively arranged on both sides of the energy consumption unit 300 along the third direction and abut against the energy consumption unit 300; the top constraint plate 480 and the bottom constraint plate 490 are both fixedly connected to the lateral constraint plate 440.

[0083] The provision of the top constraint plate 480 and the bottom constraint plate 490 realizes the constraint of the buckling deformation of the energy consuming unit 300 as a whole on both sides along the third direction, which is beneficial to the buckling deformation of the energy consuming unit 300 along the first direction.

[0084] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the cross-sections of the top constraint plate 480 and the bottom constraint plate 490 are both T-shaped, wherein the vertical section of the T-shape abuts against the energy consumption unit 300 , and the horizontal section of the T-shape is fixedly connected to the lateral constraint plate 440 .

[0085] This structural form of the top restraint plate 480 and the bottom restraint plate 490 can not only exert an effective restraining force on the energy consumption unit 300 in the second direction, but also achieve a reliable connection with the lateral restraint plate 440 .

[0086] Please continue to refer to Figure 2 and Figure 3In this embodiment, the cross-section of the lateral constraint plate 440 is [-shaped, the vertical section of the [-shaped is connected to the first support 100, the energy consumption unit 300 and the second support 200, and the horizontal section of the [-shaped is fixedly connected to the top constraint plate 480 and the bottom constraint plate 490.

[0087] This structural form of the lateral restraint plate 440 can not only exert an effective restraining force on the energy consumption unit 300 in the third direction, but also achieve a reliable connection with the top restraint plate 480 and the lateral restraint plate 440 .

[0088] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the first support 100 may include a first connecting plate 110 and a plurality of first ribs 120 disposed on the first connecting plate 110 , wherein the first connecting plate 110 is used to connect with the energy consumption unit 300 .

[0089] This arrangement of the first support 100 can not only achieve effective connection with one end of the energy consumption unit 300, but also has a high structural strength.

[0090] Similarly, the second support 200 may include a second connecting plate 210 and a plurality of second ribs 220 disposed on the second connecting plate 210 , wherein the second connecting plate 210 is used to connect with the energy consumption unit 300 .

[0091] This arrangement of the second support 200 can not only achieve effective connection with the other end of the energy consumption unit 300, but also improve the structural strength.

[0092] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the energy consumption unit 300 is detachably connected to the first support 100, the second support 200 and the constraint unit 400.

[0093] By setting the energy absorbing unit 300 to be detachably connected to the first support 100, the second support 200 and the constraint unit 400, on the one hand, the multi-order buckling restrained energy absorbing support device can be installed with an energy absorbing unit 300 of appropriate strength according to the use conditions to meet the use requirements under various working conditions. On the other hand, after the energy absorbing unit 300 is damaged, the multi-order buckling restrained energy absorbing support device can be maintained by only replacing the energy absorbing unit 300, without the need for overall replacement, thereby greatly reducing maintenance costs.
