[0039] See also Figure 1 and Figure 2 The present invention provides a recoverable box-plate steel structure system, comprising: a structural main body 1, the structural main body 1 includes a wall 11 formed by a plurality of enclosed blocks and a plurality of reserved openings 12 provided on the wall 11; and a self-resetting energy-absorbing component, comprising a first component 21, a second component 22 and a third component 23, wherein a plurality of vertically arranged first components 21 are connected between two adjacent walls 11 in the same plane, a plurality of vertically arranged second components 22 are connected at a corner formed by two adjacent walls 11, and a third component 23 is provided at a load-bearing edge 121 of the reserved opening 12 to form a support for the wall 11 at the load-bearing edge 121, so as to constitute a self-resetting energy-absorbing device of the box-plate steel structure system.

[0040] From the foregoing, it is readily apparent that, in the box-panel steel structure system of the present invention, to enhance the self-resetting energy dissipation capability of the structural columns 1, self-resetting energy dissipation components are installed correspondingly to the walls 11 and the reserved openings 12 therein, thereby forming a self-resetting energy dissipation device for the box-panel steel structure system. This effectively addresses issues such as severe buckling and large deformation in the bottom reinforcement zone. Specifically, by installing the first component 21 between two adjacent walls 11 in the same plane, it provides energy dissipation and, after an earthquake, automatically restores the two adjacent walls 11 in the box-panel steel structure system to their original positions, thus providing a self-resetting mechanism. By installing the second component 22 at the corner formed by two adjacent walls 11, it prevents fractures at the corner due to stress concentration and also allows the corner to automatically return to its original position after deformation following an earthquake. By supporting the wall 11 at the load-bearing edge 121 of the reserved opening 12 with the third component 23, it prevents severe deformation of the corresponding reserved opening 12. By utilizing the above-mentioned first component 21, second component 22 and third component 23, a recoverable box plate steel structure system energy dissipation system can be jointly formed, which plays a good self-resetting role. At the same time, the first component 21, second component 22 and third component 23 are easy to install and dismantle.

[0041] In addition, the reserved opening 12 in the present invention can be a reserved door opening or window opening. When the reserved opening 12 is a door opening, the load-bearing edge 121 can be located only at the top of the door opening. Therefore, the third component 23 can be installed only on the load-bearing edge 121 at the top of the reserved opening 12. Of course, if the bottom of the door opening also has a load-bearing edge 121, the third component 23 can also be installed on the load-bearing edge 121 at the bottom of the door opening. When the reserved opening 12 is a window opening, the load-bearing edge 121 is located on the upper and lower sides of the window opening. Therefore, the third component 23 can be installed on the corresponding load-bearing edges 121 on the upper and lower sides of the window opening. Of course, the load-bearing edge 121 of the window opening can also be set at other positions of the window opening as needed.

[0042] See also Figure 1 , Figure 1 In one embodiment, the structural body 1 of the recoverable box-panel steel structure of the present invention comprises a plurality of enclosed walls 11, a plurality of pre-reserved openings 12 provided in the walls 11, and a top plate 13 mounted on top of the walls 11. The pre-reserved openings 12 comprise door openings formed in the walls 11. Adjacent walls 11 in the same plane are connected by a first assembly 21 to dissipate energy during an earthquake and automatically restore the walls 11 to their original positions after an earthquake.

[0043] See also Figure 2 , Figure 2 In one embodiment, the structural body 1 of the resilient box-panel steel structure of the present invention comprises a plurality of enclosed walls 11 and a plurality of pre-reserved openings 12 provided in the walls 11. The pre-reserved openings 12 include door openings and window openings provided in the walls 11. Adjacent walls 11 within the same plane are connected by a first assembly 21 to dissipate energy during an earthquake and automatically restore the walls 11 to their original positions after an earthquake. The corners formed by adjacent walls 11 are connected by a second assembly 22 to prevent fractures due to stress concentration at the corners and to automatically restore the corners to their original positions if deformed after an earthquake. The load-bearing edges 121 above and below the window openings, as well as the load-bearing edge 121 at the top of the door opening, support the walls 11 via the second assembly 22, preventing severe deformation of the corresponding door or window openings during an earthquake.

[0044] like Figure 3 As shown, the first component 21 includes: a compression energy dissipation component 211; an inner core plate component 212, the inner core plate component 212 is arranged on both sides of the compression energy dissipation component 211 along the compression energy dissipation direction; a connector 213, the connector 213 is connected between the compression energy dissipation components 211, and part of the connector 213 passes through the inner core plate component 212; an end plate 214, one side of the end plate 214 is snap-connected to the outer side of the inner core plate component 212, and the other side of the end plate 214 is connected to the stiffening rib on the wall 11; and a folding memory member 215, the folding memory member 215 is connected between the end plates 214, when subjected to earthquake loads, the bottom reinforcement area will be subjected to reciprocating cyclic loads, during which the compression energy dissipation component 211 begins to compress and dissipate energy, at which time the folding memory member 215 folds back and forth to generate heat, and self-recovers and straightens after heating, playing a self-resetting role.

[0045] In this embodiment, when the first assembly 21 is installed between two adjacent walls 11 in the same plane, a portion of the connector 213 is sequentially passed through the inner core panel assembly 212, the compression energy dissipation assembly 211, and the inner core panel assembly 212 on the other side, and another portion of the connector 213 is then passed through the inner core panel assembly 212 on both sides of the compression energy dissipation assembly 211, thereby achieving the installation of the inner core panel assembly 212 on both sides of the compression energy dissipation assembly 211. Then, the end plates 214 are snap-fitted to the outer sides of the inner core panel assembly 212, and the foldable memory member 215 is connected between the two symmetrically arranged end plates 214. During an earthquake, the compression energy-absorbing component 211 will be compressed to absorb energy. At the same time, the folding memory component 215 will fold and generate heat when the compression energy-absorbing component 211 is compressed to absorb energy. In the process of heat dissipation from the heated state, the folding memory component 215 will self-recover, thereby achieving a self-resetting energy-absorbing effect by utilizing the compression energy-absorbing component 211, the inner core plate component 212, the connector 213, the end plate 214 and the folding memory component 215.

[0046] See also Figure 5 , Figure 5 In one embodiment, the foldable memory member 215 may be a foldable memory alloy. The foldable memory alloy is configured as a foldable structure. When the first component 21 begins to consume energy, the foldable memory alloy begins to heat up. After heating, the foldable memory alloy straightens, thereby achieving a self-resetting effect.

[0047] like Figure 4 、 Figure 6 and Figure 7 As shown, the compression energy dissipation assembly 211 includes: a compressible central column 2111; compression columns 2112 connected at both ends of the compressible central column 2111; first compression elastic members 2113, a plurality of which are connected between the compression columns 2112 to adjust the deformation of the compressed compressible central column 2111 and achieve self-recovery; and a compression plate 2114 mounted on the outside of the compression columns 2112. The outside of the compression plate 2114 is connected to the inner core plate assembly 212, and the compression plate 2114 is provided with a first through-hole 21141 for a portion of the connecting member 213 to pass through. The first compression elastic members 2113 can be compression springs, or other elastic structural members.

[0048] In this embodiment, the compression energy dissipation assembly 211 primarily comprises a compressible central column 2111, a compression column 2112, a first compression elastic member 2113, and a compression plate 2114. Compression columns 2112 are mounted at both ends of the compressible central column 2111. Multiple first compression elastic members 2113 are arranged between the two compression columns 2112. The compression plate 2114 is then mounted on the outside of the compression columns 2112. The outside of the compression plate 2114 is connected to the inner core plate assembly 212. This allows the compression column 2112 to dissipate energy through compression. The first compression elastic members 2113 and the compression column 2112, as well as the connection between the connector 213 and the first through-hole 21141, adjust the deformation of the compressible central column 2111 and the foldable memory member 215, thereby achieving a self-resetting effect. Furthermore, the compressible central column 2111 enhances the overall rigidity of the compression energy dissipation device.

[0049] like Figure 4 、 Figure 6 、 Figure 8 and Figure 9 As shown, the inner core plate assembly 212 includes: a cross plate 2121, a second through-hole 21211 for the connecting member 213 to pass through is provided on the cross plate 2121, and one side of the cross plate 2121 is connected to the compression energy dissipation assembly 211; a compressible sleeve 2122, which is installed in the middle of the other side of the cross plate 2121, and the compressible sleeve 2122 is provided with a plurality of hanging holes 21221 along the circumference; a stretching and dragging frame 2123, one end of which is detachably inserted into the hanging hole 21221, and the stretching and dragging frame 2123 The other end extends to the corresponding end of the cross plate 2121; and the limiting buckle 2124, the limiting buckle 2124 detachably buckles the other end of the stretching and dragging frame 2123 and the corresponding end of the cross plate 2121 to put the compressible sleeve 2122 in a compressed state; wherein, when the end plate 214 is installed on the compressible sleeve 2122, the limiting buckle 2124 and the stretching and dragging frame 2123 are removed, so that the compressible sleeve 2122 elastically extends out to cooperate with the end plate 214, and the end plate 214 forms a buckle connection with the hook hole 21221.

[0050] In this embodiment, during the installation of the inner core plate assembly 212, the second perforation 21211 on the cross plate 2121 is utilized to enable the connector 213 to slide through. The cross plate 2121 may be obtained by first splicing a horizontal plate and a vertical plate. Of course, it may also be a "cross" shape punched or cut out from a whole plate. In order to improve the stability after installation, it may also be other shapes, such as a "rice" shape. Before installing the connector 213, the cross plate 2121 is first installed with the compression plate 2114 of the compression energy dissipation assembly 211. Specifically, the compression plate 2114 may be connected along the horizontal direction of the cross plate 2121 by welding. Of course, other installation methods may also be used along other directions of the cross plate 2121 to achieve installation and fixation. On the cross plate 2121, in order to facilitate the installation of the end plate 214, the stretching and dragging frame 2123 can be inserted into each hook hole 21221 of the compressible sleeve 2122, and then squeezed toward one side of the cross plate 2121 to put the compressible sleeve 2122 into a compressed state, and then the relative position of the stretching and dragging frame 2123 and the cross plate 2121 is fixed by using the limiting buckle 2124. After the end plate 214 and the foldable memory member 215 are installed and connected and placed at the corresponding position outside the cross plate 2121, the limiting buckle 2124 and the stretching and dragging frame 2123 are removed, so that the compressible sleeve 2122 can be elastically extended, thereby correspondingly cooperating with the end plate 214, for example, cooperating with the hanging column 2143 on the end plate 214, and then forming a snap connection through the end plate 214 and the hook hole 21221 to ensure the stability of the connection between the end plate 214 and the inner core plate assembly 212.

[0051] In addition, in order to facilitate the stretching and dragging frame 2123 to apply force toward the side of the cross plate 2121, a frame hole 21231 is opened on the stretching and dragging frame 2123 to facilitate the sliding passage of the connecting member 213, which can also realize the movement guidance of the stretching and dragging frame 2123 when applying force.

[0052] like Figure 3 、 Figure 4 and Figure 6 As shown, the connecting member 213 includes: a prestressed tendon 2131; and a nut 2132, the nut 2132 is threadedly connected to both ends of the prestressed tendon 2131, and the nut 2132 is located on a side of the inner core plate assembly 212 away from the compression energy dissipation assembly 211.

[0053] In the embodiment, the connecting piece 213 mainly comprises two parts, one part is sequentially penetrating through the second through hole 21211 on the one side cross plate 2121, the first through hole 21141 on the compression plate 2114, and the second through hole 21211 on the other side cross plate 2121, so as to simultaneously assemble the inner core plate assembly 212 and the compression energy dissipation assembly 211, and the other part is penetrating through the second through hole 21211 on the cross plate 2121 on both sides. When the connecting piece is installed, the pre-stressed tendon 2131 is penetrated through the first through hole 21141 or the first through hole 21141 and the second through hole 21211, and then the nut 2132 is locked at both ends of the pre-stressed tendon 2131 and located on the side of the cross plate 2121 of the inner core plate assembly 212, so as to realize the installation of the inner core plate assembly 212 and the compression energy dissipation assembly 211.

[0054] As shown in Figure 4 , Figure 6 , Figure 10 , the end plate 214 comprises a base plate 2141, a plurality of mounting grooves 21411 are arranged on the base plate 2141, a fixing bolt 2142 is arranged to connect the mounting groove 21411 and the stiffening rib on the wall body 11, and a hanging column 2143 is arranged on the middle of one side of the base plate 2141 to be buckled with the outer side of the inner core plate assembly 212.

[0055] In the embodiment, when the end plate 214 is assembled with the inner core plate assembly 212, the stretching pull frame 2123 is first forced to the side of the cross plate 2121, so that the compressible sleeve 2122 is in a compressed state, thereby facilitating the arrangement of the base plate 2141 and the hanging column 2143 on both sides of the cross plate 2121 and the compressible sleeve 2122. Then, the stretching pull frame 2123 is removed, and the compressible sleeve 2122 is elastically stretched out at this time, so that the hanging column 2143 is inserted into the compressible sleeve 2122, and the hanging column 2143 is further buckled with the hanging buckle hole 21221 on the compressible sleeve 2122 to increase the connection stability.

[0056] Specifically, when the other side of the base plate 2141 is connected with the end wall of the wall body 11, the fixing bolt 2142 can be used to penetrate through the mounting groove 21411 to assemble with the T-shaped rib web on the side end of the wall body 11, thereby facilitating disassembly.

[0057] As shown in Figure 10 , the hanging column 2143 comprises a column body 21431 and a compressible protrusion 21432 arranged on the side surface of the column body 21431 in the circumferential direction to be buckled with the inner core plate assembly 212.

[0058] After the stretching and dragging frame 2123 is removed, the compressible sleeve 2122 will elastically extend, allowing the column 21431 to be inserted into the compressible sleeve 2122. At the same time, the compressible protrusion 21432 on the column 21431 will be further inserted into the hook hole 21221 arranged along the radial direction of the compressible sleeve 2122, thereby forming a snap connection, thereby increasing the stability of the end plate 214 and the inner core plate assembly 212 after assembly.

[0059] like Figure 11 As shown, the second component 22 includes: a second compression elastic member 221; and a sector block 222. The center positions of the plurality of sector blocks 222 correspond to each other, and adjacent two sector blocks 222 form a preset initial angle with each other. The plurality of second compression elastic members 221 are connected between adjacent two sector blocks 222 at the preset initial angle. The outer surfaces of the two outermost sector blocks 222 are connected to the wall 11 at the corner to achieve self-reset energy dissipation at the corner of the wall 11. The second compression elastic member 221 can be a compression spring, or of course, other elastic structural members.

[0060] In this embodiment, when the second component 22 is installed at the corner formed by two adjacent walls 11, a plurality of sector blocks 222 can be provided, each of which is sector-shaped and arranged along a common center circumference. A preset initial angle is left between each two adjacent sector blocks 222 to facilitate connection with the second compressive elastic member 221. Because the second compressive elastic member 221 needs to match the preset initial angle between adjacent sector blocks 222, the length of the second compressive elastic member 221 connected sequentially along the radial direction of the sector blocks 222 continuously decreases. Then, on the two outermost fan-shaped blocks 222, when the side that is not connected to the second compression elastic member 221 is connected to the wall 11 at the corner, it can be a welding connection, of course, it can also be a fixed connection in other ways to achieve self-resetting energy dissipation at the corner of the wall 11, which can be used to prevent the corner from being fractured due to stress concentration, and at the same time, it can also make the corner automatically return to its original position when it is deformed after an earthquake, thereby playing a self-resetting role and reducing stress concentration.

[0061] like Figure 12As shown, the third component 23 includes: an anti-bending rectangular memory block 231; a rectangular steel beam 232, the rectangular steel beam 232 is respectively arranged on both sides of the length direction of the anti-bending rectangular memory block 231, and the end surface of the rectangular steel beam 232 is against the two sides of the anti-bending rectangular memory block 231; and an anti-torsion memory connector 233, the anti-torsion memory connector 233 is connected to the load-bearing edge 121, the anti-torsion memory connector 233 is blocked on both sides of the width direction of the anti-bending rectangular memory block 231, and the two ends of the anti-torsion memory connector 233 are respectively connected to the rectangular steel beams 232 on both sides of the width direction of the anti-bending rectangular memory block 231, so as to self-recover after deformation and energy consumption at the same time as the anti-bending rectangular memory block 231.

[0062] In this embodiment, the anti-bending rectangular memory block 231 can be a solid rectangular block of memory alloy, the anti-torsion memory connector 233 can be a memory alloy connector piece to achieve rollover prevention, and the rectangular steel beam 232 is a solid rectangular steel column. The rectangular steel beam 232 serves as the primary load-bearing mechanism for the third component 23, bearing the pressure exerted by the wall 11 and earthquakes. When an earthquake causes the third component 23 to bend, the anti-bending rectangular memory block 231 and the anti-torsion memory connector 233 bend first. After the effect has subsided, the anti-bending rectangular memory block 231 and the anti-torsion memory connector 233 automatically reset.

[0063] Specifically, the anti-bending rectangular memory block 231 and the anti-torsion memory connector 233 will be squeezed and deformed during an earthquake. At the same time, the bending and twisting deformations will generate heat, causing the temperature to rise. After cooling down, the anti-bending rectangular memory block 231 and the anti-torsion memory connector 233 will automatically reset.

[0064] See also Figure 13 The present invention also provides an assembly method for the aforementioned recoverable box plate steel structure system, comprising:

[0068] The first component 21, the second component 22 and the third component 23 are assembled to form a self-resetting energy dissipation device of the box plate steel structure system.

[0069] In addition, before assembly, the walls 11 and the top plate 13 of the structural body 1 and the reserved opening 12 can all be prefabricated in a factory in advance.

[0070] In summary, the present invention discloses a recoverable box-panel steel structure system and assembly method. By utilizing a first component 21 installed between two adjacent walls 11 in the same plane, the system can dissipate energy and automatically restore two adjacent walls 11 in the same plane to their original positions after an earthquake, thus achieving a self-resetting effect. By utilizing a second component 22 installed at the corner formed by two adjacent walls 11, the system can prevent stress concentration at the corner from causing fractures and automatically restore the corner to its original position after deformation. By utilizing a third component 23 to support the wall 11 at the bearing edge 121 of the reserved opening 12, the system can prevent severe deformation of the corresponding reserved opening 12. Furthermore, by utilizing the first, second, and third components 21, 22, and 23, the system can form an energy-dissipating box-panel steel structure system, enabling the entire system to dissipate energy and self-reset before and after an earthquake. Furthermore, the first, second, and third components 21, 22, and 23 are also very easy to install and remove. Therefore, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
