Description

Technical Field

[0001] The present application relates to the field of building structure design, and in particular to a building cantilever system. Background Art

[0002] The building cantilever system is a common structural form in construction. It uses cable structures or other structures to cantilever building components from the main structure to form a cantilever structure. This structural form is widely used in buildings, such as awnings, eaves, external balconies, cantilevered corridors, etc. Among them, cantilevered corridors refer to the load-bearing structures of the second floor and above in the building that can be cantilevered from the outer wall of the building to form a continuous corridor space. With the rapid development of modern commerce and the rapid rise of shopping malls in various places, cantilevered corridors are increasingly widely used in shopping malls.

[0003] The existing cantilever corridor structure usually includes a cantilever beam for mainly bearing the load, a connecting beam for evenly distributing the load on each cantilever beam, and a steel support structure for firmly supporting the cantilever beam and the connecting beam; the current steel support structure is mostly ordinary steel structure, which is formed by splicing and welding various steel rods. Its mechanical behavior is unstable. When encountering natural disasters such as earthquakes, it reacts strongly and is prone to buckling when struck by earthquakes, resulting in a sharp drop in the mechanical properties of the steel support structure, which in turn causes the cantilever corridor structure to buckle and deform or even form local cracks, affecting the safety of the cantilever corridor structure and the overall building, and forming an adverse factor for the safety of people's lives and property. Summary of the invention

[0004] Based on this, the present application provides a building cantilever system, which can improve the seismic resistance of the cantilever corridor structure and reduce the possibility of bending and deformation of the cantilever corridor structure after an earthquake.

[0005] The application provides a building cantilever system that adopts the following technical solutions: A building cantilever system, comprising a building main body with multiple floors and a cantilevered corridor structure arranged on the side of two or more floors, wherein the cantilevered corridor structure comprises a concrete foundation, a connection system, a load-bearing system and a steel structure system arranged in sequence from top to bottom, the load-bearing system comprises a plurality of cantilevered beams vertically arranged on the building main body, and adjacent cantilevered beams are arranged equidistantly; the cantilevered beam comprises a plurality of beam-column plates, each beam-column plate is connected to an adjacent beam-column plate through a connecting member, and a displacement joint is reserved between adjacent beam-column plates; an elastic reset mechanism is arranged between two connecting members; The steel structure system includes a bottom support cantilever beam fixed to the main body of the building and multiple groups of support mechanisms slidably arranged on the bottom support cantilever beam, the support mechanism includes a sliding sleeve, a vertical column rotatably arranged on the sliding sleeve, and an adjusting column rotatably connected to the sliding sleeve, the length of the adjusting column is set to be adjustable, and a rotating seat is rotatably connected between two adjacent adjusting columns, and the rotating seat is fixed to the bottom of the beam-column plate; the length of the vertical column is set to be adjustable, the top end of the vertical column is vertically connected to the connecting member, and a first energy dissipation shock absorber is arranged inside the vertical column.

[0006] By adopting the above-mentioned technical scheme, the concrete foundation of the present application serves as the surface structure of the cantilevered corridor structure, which is firmly supported by the load-bearing system and the steel structure system, and the bearing force is dispersed to each cantilever beam and each steel structure system through the connection system, so that the cantilevered corridor structure can have good structural stability to ensure the safety of the overall building.

[0007] Among them, by adjusting the length of the adjusting column so that the rotating seat is close to and fixed to the beam-column plate, one end of the adjusting column is against the sliding sleeve and the other end supports the rotating seat, which can play a major bearing role; by adjusting the vertical column so that it is vertically fixed to the connecting member, the first energy dissipation shock absorber arranged inside the vertical column is used to absorb vibrations from above the concrete foundation when people walk or large items are transported by passing; in addition, adjacent beam-column plates can be connected to each other by connecting members to form a displacement joint, which is used as the displacement deformation interval of the beam-column plate when an earthquake occurs, and absorbs vibration energy through an elastic reset mechanism, which can greatly reduce the possibility of bending and deformation of the cantilever corridor structure and even the formation of local cracks, thereby ensuring the safety and bearing capacity of the cantilever corridor structure and the overall building, and protecting people's lives and property.

[0008] Optionally, the connecting member includes a steel structure sleeve mounted on the beam-column plate and a side extension plate integrally formed on the side of the steel structure sleeve, the side extension plate extends to the side of the adjacent beam-column plate, is arranged between adjacent side extension plates of two connecting members, and is partially opposite to each other and fixed by a first high-strength bolt; wherein, the side extension plate is provided with a through hole, and the other side extension plate is provided with a waist-shaped hole, the first high-strength bolt is sequentially passed through the through hole, the beam-column plate and the waist-shaped hole, and both ends of the first high-strength bolt are respectively locked with locking nuts.

[0009] By adopting the above technical solution, the first high-strength bolt is passed through the through hole of one of the side extension plates and is installed in the beam-column plate, and passes through the waist-shaped hole of the other side extension plate, and the two ends of the first high-strength bolt are respectively locked and fixed by locking nuts. The locking force of the locking nut and the positioning support of the bottom steel structure system can keep the two adjacent beam-column plates firmly connected. When an earthquake occurs, the first high-strength bolt can move in the waist-shaped hole, thereby forming a relative displacement between adjacent beam-column plates. At this time, the adjacent beam-column plates do not contact each other due to the setting of the displacement joint, which can reduce the possibility of bending and deformation of the beam-column plates after the earthquake, thereby reducing the possibility of bending and deformation of the cantilever corridor structure and even the formation of local cracks.

[0010] Optionally, side panels are respectively provided on both side end faces of the side extension plate, each side panel is integrally formed with the side extension plate, and a C-shaped structure is formed between the side extension plate and the two side panels; the side panels are arranged in a triangular shape, and in the assembled state, the long side of the side panel is arranged opposite to the long side of another adjacent side panel, and the long sides of the two side panels are arranged at intervals to form a displacement space.

[0011] By adopting the above technical scheme, in the assembled state, after the connecting member is fixed to the adjacent beam-column plate and the two connecting members are fixed to each other, the long side of the side plate can be spaced apart from the long side of the adjacent side plate; when an earthquake occurs, the beam-column plate is displaced toward the other beam-column plate under the action of vibration, and finally the long sides of the two side plates can abut against each other, thereby limiting the displacement range of the beam-column plate; since the two side plates are in surface contact, the impact force received by the connecting member is small, and the impact force transmitted to the beam-column plate is also small, which is conducive to reducing the bending deformation or local cracking of the beam-column plate after being subjected to force, so that the cantilevered corridor structure maintains good structural stability.

[0012] Optionally, the elastic reset mechanism includes a second energy dissipation shock absorber, two movable rods and two reset springs. An outer edge plate is provided on the side of the steel structure sleeve, and the movable rod is movably passed through the outer edge plate; a stop plate and a limit plate are respectively fixed at both ends of the movable rod, the stop plate is located on the side of the outer edge plate away from the other outer edge plate, and the limit plate is located between the two outer edge plates; the reset spring is arranged between the stop plate and the adjacent outer edge plate, and the reset spring is used to force the limit plate to rest against the adjacent outer edge plate; the second energy dissipation shock absorber is fixed between the two limit plates.

[0013] By adopting the above-mentioned technical scheme, the setting of the reset spring can always generate an elastic force acting on the resistance plate, thereby forcing the movable rod to normally stay in the extreme position where the limit plate is against the outer edge plate; when an earthquake occurs, the beam-column plate is displaced in the direction close to the adjacent beam-column plate, and the second energy dissipation shock absorber can absorb the vibration energy; at this time, the reset spring is compressed and can provide a reset force to restore the beam-column plate to its original position after the earthquake, and has a self-reset function, thereby ensuring that the cantilevered corridor structure maintains good structural stability and the service life of the overall building can be maintained for a long time.

[0014] Optionally, the vertical column includes a first pillar hinged to the sliding sleeve and a first movable column movably inserted in the first pillar, the bottom end of the first movable column is fixedly provided with a suspension plate, and the first energy dissipation shock absorber is located between the suspension plate and the first movable column; the side of the first pillar is provided with a plurality of first sockets connected to the interior, and all the first sockets are arranged at intervals along the extension direction of the first pillar; a second high-strength bolt is inserted into the first socket, and in the assembled state, the second high-strength bolt is against the side of the suspension plate away from the first energy dissipation shock absorber.

[0015] By adopting the above-mentioned technical solution, the length of the vertical column can be adjusted by moving the first movable column along the extension direction of the first support column; after the vertical column is adjusted to the required length, the second high-strength bolt is inserted into the first plug hole, and the suspension plate can be pressed against the second high-strength bolt under the elastic force of the first energy dissipation shock absorber to keep the length of the vertical column fixed; and when the concrete foundation is subjected to force above and the cantilevered corridor structure is subjected to vertical vibration, the first energy dissipation shock absorber can be deformed to absorb the vibration energy, thereby reducing the adverse effects of the vibration on the cantilevered corridor structure.

[0016] Optionally, a strip groove is provided on the side of the first pillar, and the extension direction of the strip groove is arranged in the same direction as the extension direction of the first pillar; a connecting rod is fixed on the side of the first energy dissipation shock absorber, and the connecting rod passes through the strip groove and is partially exposed from the first pillar; a rope threading barrel is provided at the end of the connecting rod, and a tensioning rope is passed through each rope threading barrel, one end of the tensioning rope is connected to the main body of the building and is located below the load-bearing system, and the other end is connected to the main body of the building and is located above the load-bearing system.

[0017] By adopting the above technical scheme, one end of the tensioning rope is connected to the main body of the building and is located below the load-bearing system, and the other end is successively passed through each rope threading drum and then bypasses the load-bearing system and is connected to the main body of the building so that it can be located above the load-bearing system; because when the cantilever corridor structure is subjected to gravity load from above, the side of the cantilever corridor structure away from the main body of the building is more prone to deformation and bending. When the load-bearing system has a tendency to bend downward, the tension of the tensioning rope will increase, thereby increasing the reaction force acting on the load-bearing system, which can overcome the downward deformation of the load-bearing system and further reduce the possibility of bending and deformation of the cantilever corridor structure and even the formation of local cracks.

[0018] Optionally, the sliding sleeve is provided with inner sleeve grooves penetrating on both sides, and the sliding sleeve is slidably sleeved on the bottom support suspension beam through the inner sleeve grooves; the two side ends of the sliding sleeve are respectively slidably connected with movable frame plates, and an elastic member is provided between the movable frame plate and the sliding sleeve; the movable frame plate is provided with a first positioning hole, and the bottom support suspension beam is provided with a second positioning hole. In the assembled state, the two movable frame plates are in extreme positions away from each other, and the first positioning hole and the second positioning hole are arranged opposite to each other and are jointly penetrated and fixed with a third high-strength bolt.

[0019] By adopting the above technical scheme, the sliding sleeve is arranged on the bottom support suspension beam through the inner sleeve groove, and the position of the sliding sleeve on the bottom support suspension beam can be easily adjusted; by setting the movable frame plate, after the first positioning hole of the movable frame plate is aligned with the second positioning hole of the bottom support suspension beam, the movable frame plate is fixedly connected to the bottom support suspension beam using the third high-strength bolt, and the sliding sleeve can move between the two movable frame plates, and then when an earthquake occurs and the beam-column plate is vibrated and lateral displacement occurs, the sliding sleeve can move slightly with the beam-column plate, and use the elastic member to absorb the vibration energy, thereby reducing the possibility of bending deformation or even local cracks in the cantilever corridor structure.

[0020] Optionally, the elastic member is configured as a tension spring, one end of which is hooked and fixed to the movable frame plate, and the other end of which is hooked and fixed to the sliding sleeve.

[0021] By adopting the above technical solution, the setting of the tension spring can always generate elastic force acting on the sliding sleeve, and the two tension springs on both sides of the sliding sleeve can be in a force balance state, which is also conducive to the automatic resetting of the sliding sleeve after the earthquake, ensuring that the cantilevered corridor structure maintains good structural stability.

[0022] Optionally, the bottom support cantilever beam is arranged in an arc shape, and the distance between the bottom support cantilever beam and the cantilever beam gradually increases from one end of the bottom support cantilever beam close to the building body to the other end; an auxiliary support frame is provided on the side of the building body, and the auxiliary support frame is connected to the middle position of the bottom support cantilever beam.

[0023] By adopting the above-mentioned technical scheme, by setting the bottom support cantilever beam in an arc shape, the distance between the side of the bottom support cantilever beam away from the main body of the building and the load-bearing system is larger, which can improve the supporting strength of the load-bearing system and ensure the structural stability of the cantilever corridor structure; the distance between the side of the bottom support cantilever beam close to the main body of the building and the load-bearing system is smaller, which can reduce the situation where the bottom of the auxiliary support frame is lower than the bottom support cantilever beam, and facilitate the installation of decorative panels after the cantilever corridor structure is completed to hide the load-bearing system and the steel structure system, thereby improving the aesthetics of the cantilever corridor structure.

[0024] Optionally, the adjustment column includes a second pillar hinged to the sliding sleeve and a second movable column movably inserted in the second pillar, and the end of the second movable column is rotatably connected to the rotating seat; the side of the second support is provided with a plurality of second sockets connected to the interior, and all the second sockets are arranged at intervals along the extension direction of the second pillar; a fourth high-strength bolt is inserted into the second socket, and in the assembled state, the fourth high-strength bolt abuts against the side end surface of the second movable column away from the rotating seat.

[0025] By adopting the above-mentioned technical solution, the length of the adjustment column can be adjusted by moving the second movable column along the extension direction of the second support column, thereby adjusting the height of the rotating seat; after the rotating seat is adjusted to the required length, the rotating seat is fixed to the beam-column plate, and then the fourth high-strength bolt is inserted into the second plug hole, and the end of the second movable column away from the rotating seat can abut against the fourth high-strength bolt, thereby keeping the length of the adjustment column fixed, which is used to firmly support each beam-column plate and ensure the structural stability of the cantilevered corridor structure.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Connect adjacent beams, columns and slabs through connecting components to form displacement joints. The displacement joints can serve as the displacement deformation interval of beams, columns and slabs when an earthquake occurs, and absorb vibration energy through elastic reset mechanisms, which can greatly reduce the possibility of buckling and deformation of the cantilevered corridor structure and even the formation of local cracks; 2. The first energy dissipation shock absorber arranged inside the vertical column can absorb the vibration energy from above the concrete foundation when people walk or when large items are transported, thereby reducing the adverse effects of vibration on the cantilever corridor structure; 3. By setting up the tension ropes, when the load-bearing system has a tendency to bend downward, the tension of the tension ropes will increase, thereby increasing the reaction force acting on the load-bearing system, which can overcome the downward deformation of the load-bearing system and further reduce the possibility of bending and deformation of the cantilever corridor structure or even the formation of local cracks.

[0029] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0030] The embodiment of the present application discloses a building cantilever system.

[0031] Reference Figure 1 A building cantilever system includes a building main body 1 with multiple floors and a cantilever corridor structure arranged on the sides of two or more floors; the cantilever corridor structure includes a concrete foundation 2, a connection system 3, a load-bearing system 4 and a steel structure system 5 arranged in sequence from top to bottom. During the construction of the cantilever corridor structure, it is usually constructed in the order of the steel structure system 5, the load-bearing system 4, the connection system 3 to the concrete foundation 2, from bottom to top.

[0032] Among them, the steel structure system 5 includes a bottom support suspension beam 51 and a supporting mechanism. The bottom support suspension beam 51 is fixed to the side of the building body 1, and the bottom support suspension beam 51 is arranged in an arc shape as a whole. The height from the bottom support suspension beam 51 to the ground gradually decreases from one end of the bottom support suspension beam 51 close to the building body 1 to the other end; an auxiliary support frame 11 is fixedly installed on the side of the building body 1, the auxiliary support frame 11 is located below the bottom support suspension beam 51, and the auxiliary support frame 11 is partially fixed to the middle position of the bottom support suspension beam 51, which is used to provide auxiliary support for the bottom support suspension beam 51.

[0033] There are multiple groups of support mechanisms, and each group of support mechanisms is slidably arranged on the bottom support suspension beam 51; it should be noted here that the fixed connection between the auxiliary support frame 11 and the bottom support suspension beam 51 needs to be after the support mechanism is slidably arranged and fixed on the bottom support suspension beam 51. Figure 2 The supporting mechanism includes a sliding sleeve 52, a vertical column 53 and an adjusting column 54. The sliding sleeve 52 is an arc-shaped sleeve member. An inner sleeve groove 521 is provided in the middle of the sliding sleeve 52. The inner sleeve groove 521 passes through two opposite side surfaces of the sliding sleeve 52. The inner size of the inner sleeve groove 521 is set to be equal to the outer size of the bottom support suspension beam 51, so that the sliding sleeve 52 can be slidably sleeved on the bottom support suspension beam 51 through the inner sleeve groove 521.

[0034] In addition, movable frame plates 522 are respectively provided on the end surfaces of both sides of the sliding sleeve 52, and each movable frame plate 522 is slidably connected to the sliding sleeve 52 through a telescopic connecting rod 523, and the movable frame plate 522 can also be slidably sleeved on the bottom support suspension beam 51; an elastic member is provided between each movable frame plate 522 and the sliding sleeve 52, and the elastic member in this embodiment is a tension spring 524, one end of the tension spring 524 is hooked and fixed to the sliding sleeve 52, and the other end is hooked and fixed to the movable frame plate 522; in the initial state, the tension spring 524 can normally generate an elastic force acting on the movable frame plate 522, thereby making the movable frame plate 522 located in a position abutting against the sliding sleeve 52.

[0035] Reference Figure 3 The movable frame plate 522 is provided with a first positioning hole 5221 which passes through both sides, and the bottom support suspension beam 51 is provided with a second positioning hole 511 which passes through both sides, and the first positioning hole 5221 and the second positioning hole 511 are jointly connected and fixed with a third high-strength bolt 525; when the sliding sleeve 52 moves to a specific position of the bottom support suspension beam 51, the first positioning hole 5221 of the movable frame plate 522 in the initial state can be misaligned with the second positioning hole 511; at this time, the movable frame plate 522 is forced to move so that the first positioning hole 5221 and the second positioning hole 511 are in a position facing each other, and then the third high-strength bolt 525 is connected and fixed to the first positioning hole 5221 and the second positioning hole 511, so that the two movable frame plates 522 can be firmly fixed to the bottom support suspension beam 51 respectively; at this time, the tension spring 524 is in a tensioned state, and the sliding sleeve 52 can make a small displacement in the area between the two movable frame plates 522.

[0036] Back to Figure 1The adjustment column 54 includes a second pillar 541 and a second movable column 542. The second pillar 541 is hinged to the top of the sliding sleeve 52. The second pillar 541 is provided with a second movable slot at one end away from the sliding sleeve 52. The second movable column 542 is movably inserted in the second movable slot. The length of the adjustment column 54 can be adjusted by moving the second movable column 542 in the second movable slot. The second movable column 542 is rotatably connected to a rotating seat 543 at one end away from the second pillar 541. The two second movable columns 542 respectively located in the two sets of sliding sleeves 52 are rotatably connected to the rotating seat 543. The rotating seat 543 is used to be fixed to the load-bearing system 4, so that the adjustment column 54 plays a major supporting role for the load-bearing system 4.

[0037] Specific reference Figure 4 A plurality of second insertion holes 5411 are provided on the side of the second pillar 541, each of the second insertion holes 5411 is connected to the second movable slot, and all the second insertion holes 5411 are equidistantly arranged along the extension direction of the second pillar 541; a fourth high-strength bolt 544 is inserted into the second insertion hole 5411, and when the second movable column 542 moves in a direction away from the second pillar 541 and the length of the adjustment column 54 is determined, the fourth high-strength bolt 544 is inserted into the second pillar 541, and the distance between adjacent second insertion holes 5411 is reduced, so that the side end face of the second movable column 542 away from the rotating seat 543 can be firmly pressed against the fourth high-strength bolt 544, so that the adjustment column 54 can provide good support for the load-bearing system 4.

[0038] It should also be noted that here, by designing the gap between adjacent second holes 5411 to be narrower and arranging each second hole 5411 on two opposite sides of the second pillar 541, it is possible for each fourth high-strength bolt 544 to be able to abut against each other in sequence after being correspondingly inserted into each second hole 5411, thereby greatly improving the bearing capacity of the adjustment column 54, so as to ensure that the steel structure system 5 provides stable support for the load-bearing system 4.

[0039] Back to Figure 1 The vertical column 53 includes a first support column 531 and a first movable column 532. The first support column 531 is hinged to the top of the sliding sleeve 52, and the rotation connection between the first support column 531 and the sliding sleeve 52 can be staggered with the rotation connection between the second support column 541 and the sliding sleeve 52. The first support column 531 is provided with a first movable slot at one end away from the sliding sleeve 52, and the first movable column 532 is movably inserted inside the first movable slot. The length of the vertical column 53 can be adjusted by moving the first movable column 532 in the first movable slot. The end of the first movable column 532 away from the first support column 531 can be fixed to the load-bearing system 4.

[0040] Reference Figure 5A suspension plate 533 is fixedly mounted on the bottom end of the first movable column 532, and the suspension plate 533 is spaced apart from the bottom end surface of the first movable column 532, and a first energy dissipation shock absorber 535 is fixedly installed between the suspension plate 533 and the first movable column 532; a plurality of first plug holes 5311 are opened on the side of the first pillar 531, each first plug hole 5311 is connected to the first movable slot, and all the first plug holes 5311 are equidistantly arranged along the extension direction of the first pillar 531; the first plug holes 5311 are arranged on the side of the first pillar 531, each first plug hole 5311 is connected to the first movable slot, and all the first plug holes 5311 are equidistantly arranged along the extension direction of the first pillar 531; A second high-strength bolt 534 is inserted into the hole 5311. When the first movable column 532 moves away from the first support column 531 and the length of the vertical column 53 is determined, the second high-strength bolt 534 is inserted into the first insertion hole 5311. The suspension plate 533 can be tightened against the second high-strength bolt 534 under the elastic force of the first energy dissipation shock absorber 535, thereby keeping the length of the vertical column 53 fixed, so as to facilitate the vertical column 53 to be vertically connected to the load-bearing system 4.

[0041] Back to Figure 1 The load-bearing system 4 includes a plurality of cantilever beams vertically arranged on the side of the building body 1, and adjacent cantilever beams are arranged equidistantly; wherein, the cantilever beams include a plurality of beam-column plates 41, and the side end faces of each beam-column plate 41 are fixedly connected to the adjacent beam-column plates 41 through connecting members 42. It should be noted here that the length of the beam-column plates 41 can be predetermined before construction, and the length of the beam-column plates 41 can be used to determine the position of each second positioning hole 511 on the bottom support cantilever beam 51, satisfying the relationship: the distance between the midpoint between two adjacent second positioning holes 511 and the midpoint between another group of adjacent second positioning holes 511 can be equal to the length of the beam-column plates 41.

[0042] When the steel structure system 5 is completed and the load-bearing system 4 is constructed, the beam-column plate 41 is fixedly installed on the rotating seat 543 so that the connection position between the beam-column plate 41 and the rotating seat 543 is located in the center of the beam-column plate 41. At this time, the vertical column 53 can be aligned with the distance between two adjacent beam-column plates 41, so that the vertical column 53 can be vertically connected to the connecting member 42.

[0043] Reference Figure 6 The connecting member 42 includes a steel structure sleeve 421, a side extension plate 422, a side plate 423 and an outer edge plate 424, wherein the side extension plate 422 is integrally formed on the side of the steel structure sleeve 421. When the steel structure sleeve 421 is matched and sleeved on the beam-column plate 41, the side extension plate 422 can extend to the side of the adjacent beam-column plate 41; at this time, the adjacent side extension plates 422 respectively arranged on the two connecting members 42 can be partially opposite, and the two side extension plates 422 are fixedly connected by the first high-strength bolts 43, and the first high-strength bolts 43 can be penetrated through the beam-column plate 41.

[0044] Specific reference Figure 7, one of the side extension plates 422 is provided with a through hole 4221, and the other adjacent side extension plate 422 is provided with a waist-shaped hole 4222; the beam-column plate 41 is provided with a through hole 411 that passes through both sides. By passing the first high-strength bolt 43 through the through hole 4221, the through hole 411 and the waist-shaped hole 4222 in sequence, and locking the locking nuts 431 at both ends of the first high-strength bolt 43 respectively, the connecting member 42 can be fixed to the beam-column plate 41 where it is located, and the connecting member 42 and the adjacent connecting member 42 can also be fixed to each other. At this time, by utilizing the cooperation of the first high-strength bolt 43 and the waist-shaped hole 4222, a small displacement can be allowed after the two connecting members 42 are connected to each other, thereby allowing a small displacement between adjacent beam-column plates 41.

[0045] Back to Figure 6 It should be noted here that after the adjacent beam-column plates 41 are fixed to each other by the connecting members 42, a displacement gap 412 will be arranged and reserved between the two beam-column plates 41 to play a deformation buffering effect when an earthquake occurs, thereby reducing the possibility of deformation or cracking of the beam-column plates 41 under stress.

[0046] There are two side panels 423, which are respectively located on two opposite sides of the side extension plate 422, and each side panel 423 is integrally formed with the side extension plate 422 and the steel structure sleeve 421; the side extension plate 422 and the two side panels 423 together form a C-shaped structure. In this embodiment, the side panels 423 are in the shape of a triangle, and the long sides of the side extension plates 422 are directly opposite to the long sides of the adjacent side extension plates 422 on another connecting member 42, and the two side panels 423 are spaced apart to form a displacement space. Based on this, when the adjacent beam-column plates 41 are laterally displaced, the long sides of the two side panels 423 can abut against each other to limit the lateral displacement range of the beam-column plates 41, so that the cantilevered corridor structure maintains good structural stability.

[0047] There are also two outer edge plates 424, which are respectively arranged on both sides of the width direction of the steel structure sleeve 421, and each outer edge plate 424 is integrally formed with the steel structure sleeve 421; an elastic reset mechanism 6 is arranged between the outer edge plate 424 and the adjacent outer edge plate 424 of another connecting member 42, which can absorb the vibration energy during an earthquake and ensure the support stability of the cantilevered corridor structure.

[0048] Specifically, the elastic reset mechanism 6 includes a second energy dissipation shock absorber 61, two movable rods 62 and two reset springs 63. Each movable rod 62 is movably arranged in the corresponding outer edge plate 424. A stop plate 621 and a limit plate 622 are fixed to both ends of the movable rod 62. The stop plate 621 is located on the side of the outer edge plate 424 away from the other outer edge plate 424, and the limit plate 622 is located between the two outer edge plates 424. The second energy dissipation shock absorber 61 is installed between the two limit plates 622. The second energy dissipation shock absorber 61 is configured to absorb vibration energy when an earthquake occurs, so as to reduce the possibility of bending and deformation of the cantilever corridor structure or even the formation of local cracks.

[0049] The two return springs 63 are respectively correspondingly mounted on the two movable rods 62, one end of the return spring 63 abuts against the stop plate 621 of the movable rod 62, and the other end of the return spring 63 abuts against the outer edge plate 424; the return spring 63 can always generate elastic force acting on the stop plate 621, thereby forcing the limit plate 622 to normally abut against the side edge plate. At this time, the two beam-column plates 41 are in extreme positions away from each other; after an earthquake occurs, the setting of the return spring 63 can force the beam-column plate 41 to automatically reset, so as to ensure that the cantilevered corridor structure maintains good structural stability, and the service life of the overall building can be maintained for a longer time.

[0050] In addition, back to Figure 5 A strip groove 5312 is provided on the side of the first pillar 531, and the extension direction of the strip groove 5312 is arranged in the same direction as the extension direction of the first pillar 531; a connecting rod 536 is fixed on the side of the first energy dissipation shock absorber 535, and the connecting rod 536 passes through the strip groove 5312 and is partially exposed on the first pillar 531, and a rope threading barrel 537 is welded and fixed to the exposed end of the connecting rod 536. Figure 1 , each rope tube 537 is connected with a tension rope 538, one end of the tension rope 538 is fixedly connected to the building main body 1 and is located below the beam-column slab 41, and the other end of the tension rope 538 is fixedly connected to the building main body 1 and is located above the beam-column slab 41; when the cantilever corridor structure is subjected to gravity load and the side of the cantilever corridor structure away from the building main body 1 has a tendency to bend downward, the tension of the tension rope 538 will increase, thereby increasing the reaction force acting on the load-bearing system 4, which can overcome the downward deformation of the load-bearing system 4 and further reduce the possibility of bending and deformation of the cantilever corridor structure or even the formation of local cracks.

[0051] Back to Figure 1The connection system 3 includes a plurality of connection beams 31 arranged on the top of the cantilever beams, each connection beam 31 is arranged across each cantilever beam, and all the connection beams 31 are arranged equidistantly along the extension direction of the cantilever beams. The concrete foundation 2 is obtained by laying templates and pouring concrete on the top of each connection beam 31, and is used as the surface foundation of the cantilever corridor structure. When the cantilever corridor structure is subjected to load, the load can be dispersed to each group of cantilever beams and each group of steel structure systems 5 through the connection beams 31, so as to ensure the structural stability of the cantilever corridor structure.

[0052] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
