Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more particularly to a vibration isolation connection system. Background Technology

[0002] As the main evacuation route, the seismically isolated elevator is one of the key components of a seismically isolated building. It must meet the requirements for large deformation during an earthquake, not impede the free movement of the seismically isolated building, and also allow for the passage of people during evacuation. Seismic isolation joints need to be installed between the elevator and surrounding components, making the connection design between the seismically isolated elevator and the surrounding components extremely important. Traditional seismically isolated elevator methods, in order to meet the requirements for large deformation during seismic isolation, often employ designs that are easily damaged (to break during an earthquake to avoid hindering the movement of the seismically isolated building) or simple flexible connections, and have not formed a complete system.

[0003] Therefore, the current connection of seismic isolation elevators has the following problems: First, the connection is not systematic, with various connections to the ground, walls, and ceiling, resulting in inconsistent seismic isolation effects and failing to fully consider issues such as preventing falls after large deformations during earthquakes; second, traditional connection designs that are easily damaged do not consider normal use under seismic loads, requiring modifications after earthquakes; and third, traditional simple soft connection methods have low stiffness, affecting aesthetics and lacking rigidity during normal use. Summary of the Invention

[0004] The purpose of this invention is to provide a seismic isolation connection system that, through the cooperation of fixed and movable hinges, meets the requirements for large deformation during earthquakes, does not hinder the free movement of the seismically isolated building, and maintains structural stability through the hinge connection. The specific technical solution is as follows: A seismic isolation connection system for movable connection between an elevator shaft and a building structure includes a wall panel assembly, a first fixed hinge mounted on the elevator shaft, a second fixed hinge mounted on the building structure, and a movable hinge positioned between the first and second fixed hinges. The two ends of the movable hinge are connected to the first and second fixed hinges respectively via the wall panel assembly, so that the two ends of the wall panel assembly can move with the first elevator shaft and the building structure respectively.

[0005] Furthermore, the wall panel assembly includes a first plate portion disposed between a first fixed hinge and a movable hinge, and a second plate portion disposed between a second fixed hinge and a movable hinge, the second plate portion being disposed corresponding to the elevator shaft, and the first plate portion being disposed perpendicular to the second plate portion.

[0006] Furthermore, it also includes a sliding part; the movable hinge includes a rod, and a sliding part is provided on the end of the rod.

[0007] Furthermore, the width of the first plate is greater than the width of the second plate, and the thickness of the first plate is less than the thickness of the second plate.

[0008] Furthermore, it also includes a first fireproof section, the two ends of which are connected to the elevator shaft and the building structure, respectively, and the first fireproof section is set in correspondence with the first panel section.

[0009] Furthermore, it also includes a cover plate assembly disposed above the wall panel assembly, the cover plate assembly including a third plate portion, one end of the third plate portion being slidably connected to the elevator shaft, and the other end of the third plate portion being rotatably connected to the building structure.

[0010] Furthermore, it also includes an arc-shaped wall, which is installed on the elevator shaft, and the cover plate assembly also includes casters, which are correspondingly installed with the arc-shaped wall.

[0011] Furthermore, it also includes cables, the two ends of which are connected to the upper side of the third plate and the building structure, respectively.

[0012] Furthermore, it also includes a second fireproof section, the two ends of which are connected to the elevator shaft and the building structure, respectively. The second fireproof section is set up in correspondence with the third panel section.

[0013] Furthermore, it also includes a base plate assembly, which is located below the wall panel assembly. The base plate assembly includes interlocking comb tooth structures and pulley structures located at both ends of the comb tooth structures. The gaps on the comb tooth structures correspond to the curved walls, and the tracks on the pulley structures correspond to the casters.

[0014] The seismic isolation connection system of the present invention has the following advantages: 1. By cooperating with the first fixed hinge, the second fixed hinge, and the movable hinge, the two ends of the wall panel assembly can move flexibly with the elevator shaft and the building structure, respectively. This achieves a movable connection between the elevator shaft and the building structure, meets the requirements for large deformation during earthquakes, does not hinder the free movement of the seismic isolation building, maintains structural stability through the hinge connection, avoids damage caused by rigid transmission in traditional connection methods, and ensures the safety of personnel passage during evacuation.

[0015] 2. The L-shaped wall panel assembly, through its mutually perpendicular first and second panels, precisely fills the corner gap between the elevator shaft and the building structure without occupying the elevator door passage space. It also enhances connection stability with the rigidity of the L-shaped structure, preventing swaying during normal use. At the same time, with the movable hinge as the core linkage, it achieves bidirectional movement without dead points under seismic action. It does not hinder the relative deformation of the two, and the corresponding setting of the second panel and the elevator shaft forms a protective barrier, effectively preventing the risk of falling after large deformation.

[0016] 3. The sliding part at the end of the movable hinge rod enables low-friction horizontal relative sliding between the wall panel assembly and the base plate assembly. The movable and fixed hinges arranged in parallel further expand the range of seismic isolation deformation adaptation. It can flexibly respond to the bidirectional relative displacement of the two during an earthquake, avoid motion interference or structural jamming, reduce deformation resistance, protect connection nodes, and maintain the vertical connection rigidity between the wall and the base plate, thereby improving the flexibility and durability of the seismic isolation connection.

[0017] 4. The wide and thin design of the first plate not only allows for sufficient horizontal deformation travel to accommodate the relatively large dynamic deformation on one side of the elevator shaft, but also enhances flexibility to better respond to seismic deformation. The narrow and thick design of the second plate not only accommodates the small deformation requirements on the building side and avoids spatial redundancy, but also strengthens the connection rigidity, solving the problem of insufficient stiffness in traditional soft connections. Together, they balance deformation flexibility in seismic isolation scenarios with connection stability during normal use, ensuring both traffic safety and seismic isolation effectiveness.

[0018] 5. The first fireproof section forms a fireproof flexible connection with the elevator shaft and building structure at both ends, effectively achieving fire isolation between the elevator entrance and the elevator shaft, and preventing the building's fire compartment from failing due to the vertical connection of the elevator shaft; at the same time, it works with the first fixing plate to enhance stability and aesthetics, and improve the safety performance of the vibration isolation elevator.

[0019] 6. The cover plate assembly above the wall panel assembly is designed to slide with one end of the third plate to the elevator shaft and rotate with the building structure. This design not only fills the gap between the upper side of the elevator shaft and the building structure, strengthening fall protection, but also flexibly adapts to the lateral or longitudinal relative displacement of the two on the horizontal plane, avoiding movement interference or structural jamming during deformation. At the same time, it works in conjunction with the wall panel assembly to form a closed system, further consolidating the airtightness of the fire compartment and blocking the flow of smoke, thus solving the shortcomings of traditional connections in terms of ceiling protection and seismic isolation.

[0032] To better understand the purpose, structure, and function of this invention, the seismic isolation connection system of this invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 4 As shown, the seismic isolation connection system of the present invention is used to connect the elevator shaft 1 and the building structure 2. The elevator shaft 1 is fitted inside the passage of the building structure 2 and is spaced apart from the passage wall so that the elevator shaft 1 has space for displacement in the passage during an earthquake. The elevator shaft 1 is vertically connected to form an elevator shaft 6. The elevator 3 runs in the elevator shaft 6. An elevator door is provided on the side where the elevator shaft 1 is connected to the building structure 2 for passage.

[0034] It is understandable that the seismic isolation connection system consists of two symmetrical structures set on both sides of elevator door 4. Therefore, the following description will only focus on one side, while the other side will be set symmetrically and will not be elaborated further.

[0035] like Figure 2 As shown, the seismic isolation connection system includes a wall panel assembly 5. One side of the wall panel assembly 5 is fixedly connected to the left wall 8 of the elevator shaft 1 via a first fixed hinge 7, and the other side of the wall panel assembly 5 is fixedly connected to the first wall 10 of the building structure 2 via a second fixed hinge 9. A movable hinge 11 is also provided on the wall panel assembly 5. The movable hinge 11, the first fixed hinge 7, and the second fixed hinge 9 are arranged parallel to each other and perpendicular to the horizontal plane.

[0036] It is important to emphasize that the first fixed hinge 7 is fixedly connected to the wall panel assembly 5 and the left cylindrical wall 8, and will undergo seismic isolation deformation synchronously with the left cylindrical wall 8; the second fixed hinge 9 is fixedly connected to the wall panel assembly 5 and the first wall 10, and will move synchronously with the first wall 10; while the movable hinge 11, as the middle movable node on the wall panel assembly 5, can rotate around its own axis. At the same time, in conjunction with the rotation of the first fixed hinge 7 and the second fixed hinge 9, the wall panel assembly 5 can flexibly rotate and adjust its posture in the horizontal direction, thereby adapting to the horizontal relative displacement between the elevator shaft 1 and the building structure 2 during an earthquake. This not only blocks the rigid transmission of seismic energy through flexible rotation and avoids structural collision damage, but also maintains the connection stability of the wall panel assembly 5, ensuring the safety of passage in the elevator door area, and achieving a unity of connection stability and seismic isolation flexibility.

[0037] Preferably, the wall panel assembly 5 is L-shaped, including a first plate portion 12 located between the first fixed hinge 7 and the movable hinge 11, and a second plate portion 13 located between the second fixed hinge 9 and the movable hinge 11. The second plate portion 13 is correspondingly arranged with the left side cylinder wall 8, while the first plate portion 12 is perpendicular to the left side cylinder wall 8. This not only fills the corner gap without occupying the passage space near the elevator door, but also improves the connection stability by utilizing the rigidity of the L-shaped structure, avoiding shaking during normal use. At the same time, the first plate portion 12 and the second plate portion 13 are linked with the movable hinge 11 as the core, and can synchronously adapt to the rotation and translation of the movable hinge 11 and the rotation of the fixed hinge, realizing bidirectional mobility without dead points under seismic action. This does not hinder the relative deformation of the elevator shaft 1 and the building structure 2, and the corresponding arrangement of the second plate portion 13 with the left side cylinder wall 8 forms a protective barrier to prevent the risk of falling after large deformation.

[0038] Furthermore, the wall panel assembly 5 is arranged perpendicular to the base plate assembly 14, and the wall panel assembly 5 is connected to the base plate assembly 14 via a sliding part 18, such as... Figure 3 As shown, the sliding part 18 is located at the end of the rod of the movable hinge 11. The sliding part 18 can adopt a structure such as a ball bearing or a miniature roller 25 to achieve low-friction horizontal relative sliding between the wall panel assembly 5 and the base plate assembly 14. It works in conjunction with the parallel-arranged movable hinge 11 and fixed hinge to further expand the range of seismic isolation deformation adaptation. It not only cooperates with the rotation and translation of the hinge to allow the wall panel assembly 5 and the base plate assembly 14 to flexibly respond to the bidirectional relative displacement of the elevator shaft 1 and the building structure 2 during an earthquake, avoiding motion interference or structural jamming, but also reduces deformation resistance and protects the connection nodes through the low-friction characteristics of the ball bearing, while maintaining the vertical connection rigidity between the wall and the base plate.

[0039] Furthermore, the width of the first plate 12 in the horizontal direction is greater than the width of the second plate 13, and the thickness of the first plate 12 is less than the thickness of the second plate 13. The first plate 12, with its longer width, provides sufficient horizontal deformation travel, which, together with the movable hinge 11, enables rotation and translation, avoiding interference or structural damage during large deformation of the elevator shaft 1. Its thinner design is to improve flexibility and better adapt to the relatively large dynamic deformation on one side of the elevator shaft 1. The second plate 13, with its shorter width, adapts to the small deformation requirements on the building side and avoids space redundancy. Its greater thickness strengthens the connection rigidity and solves the problem of insufficient rigidity in traditional soft connections. The two work together to ensure the deformation flexibility in the seismic isolation scenario and maintain the connection stability during normal use, taking into account both traffic safety and the effect of seismic isolation.

[0040] Furthermore, it also includes a first fireproof section 15 and a first fixing plate 16. The two ends of the first fireproof section 15 in the horizontal direction are fixedly connected to one end of the left cylindrical wall 8 and the second wall 17 of the building structure 2 respectively through metal rectangular tubes. The first fireproof section 15 is correspondingly located on the left side of the first plate section 12. The first fireproof section 15 adopts folded fireproof roller shutter cloth, and its bottom is provided with elastic plastic cloth tightly attached to the bottom plate assembly 14, thereby forming a fireproof soft connection with closed sides, so that a fireproof isolation is formed between the elevator entrance / exit and the elevator shaft 6, ensuring that the building fire compartment will not be vertically connected due to the elevator shaft 6. The first fixing plate 16 is connected to both ends of the first fireproof section 15 and is located between the first fireproof section 15 and the first plate section 12 to enhance the stability and aesthetics of the first fireproof section 15.

[0041] Preferred, such as Figure 4 and Figure 5 As shown, it also includes a cover plate assembly 19 disposed above the wall panel assembly 5. The cover plate assembly 19 includes a third plate portion 20 corresponding to the bottom plate assembly 14. The elevator shaft 1 includes an upper cylinder wall 23 and a boss 22 disposed on the upper cylinder wall 23. One end of the third plate portion 20 is slidably connected to the boss 22 through multiple universal wheels 21, and the other end is connected to the third wall 24 of the building structure 2. When there is a lateral or longitudinal relative displacement between the upper cylinder wall 23 and the third wall 24 on the horizontal plane, the universal wheels 21 can make one end of the third plate portion 20 slide relative to the boss 22, which not only avoids motion interference or structural jamming during deformation, but also ensures the smoothness of seismic deformation through low friction characteristics. At the same time, it fills the gap between the upper cylinder wall 23 and the third wall 24, strengthens the safety protection against falls, and further consolidates the sealing of the fire compartment to block the passage of smoke.

[0042] The structure of the universal wheel 21 is as follows: Figures 8 to 10As shown, the caster wheel 21 includes a metal hub fixed to one end of the third plate 20, and multiple rubber rollers 25 evenly distributed around the hub. The rollers 25 are fixed to the hub by metal brackets and screws, and the rollers 25 can roll independently. By decomposing the rolling direction of the rollers 25 and cooperating with the rotation of the hub, the third plate 20 can slide horizontally back and forth and left and right. The rubber rollers 25 take into account both grip and cushioning, adapting to the seismic isolation requirements between the elevator shaft 6 and the building structure 2 in earthquake-prone areas. They can accurately respond to bidirectional relative displacement in the horizontal and longitudinal directions. While ensuring smooth sliding of the third plate 20 with low friction and avoiding structural interference or jamming, the cushioning characteristics of the rubber rollers 25 absorb vibration impact and protect the connection nodes. Together with the cover plate assembly 19 and the wall panel assembly 5, they form a fully enclosed protection, enhancing the effects of preventing falls, preventing debris intrusion, and fireproof sealing.

[0043] Furthermore, the other end of the third plate 20 away from the caster 21 is rotatably connected to the third wall 24 of the building structure 2, so that the third plate 20 can rotate with this end as the axis. At the same time, an arc-shaped wall 26 is provided at the connection between the boss 22 and the upper cylindrical wall 23. The arc-shaped wall 26 has a downwardly concave arc surface. The caster 21 is correspondingly provided with the arc-shaped wall 26. The arc surface of the arc-shaped wall 26 plays a guiding role, guiding the end of the third plate 20 where the caster 21 is provided to slide smoothly from the boss 22 to the upper cylindrical wall 23, so as to cope with the further reduction of the distance between the elevator shaft 1 and the third wall 24, and increase the range of motion of the elevator shaft 1.

[0044] Furthermore, it also includes a cable 27, the two ends of which are connected to the upper side of the third plate 20 and the building structure 2, respectively. When an earthquake causes the distance between the elevator shaft 1 and the third wall 24 to continue to increase, it can firmly hold the end of the third plate 20 where the caster 21 is installed, preventing it from falling off the boss 22, and also ensure that the third plate 20 always remains in a horizontal position. At the same time, it does not hinder the rotational freedom of the third plate 20 and the low-friction sliding of the caster 21 along the arc-shaped wall 26. It forms a dual effect of flexible constraint and rigid guidance with the hard limit of the arc-shaped wall 26, which not only meets the requirements of two-way deformation of seismic isolation, but also strengthens the connection stability of the cover plate assembly 19. Furthermore, it also includes a second fireproof section 28 and a second fixing plate 29. The two ends of the second fireproof section 28 in the horizontal direction are connected to the upper wall 23 of the elevator shaft 1 and the third wall 24 of the building structure 2 via metal rectangular tubes, respectively. The second fireproof section 28 is positioned above the third plate section 20. The second fireproof section 28 uses folded fireproof roller shutter fabric, with elastic plastic fabric tightly attached to the building structure 2 around its perimeter, thus forming a fireproof flexible connection that creates a fireproof barrier between the elevator entrance / exit and the elevator shaft 6, ensuring that the building's fire compartments are not vertically connected by the elevator shaft 6. The second fixing plate 29 is connected to both ends of the second fireproof section 28 and is located below the second fireproof section 28 to enhance its stability and prevent it from sagging downwards.

[0045] Preferred, such as Figure 6 and Figure 7 As shown, the base plate assembly 14 is located below the wall panel assembly 5. The base plate assembly 14 includes a comb structure 30 that is interlocked with each other and a pulley assembly located at both ends of the comb structure 30. The gaps on the comb structure 30 are arranged at intervals and the extension direction is perpendicular to the arc wall 26. It can flexibly expand and contract with the relative displacement of the elevator shaft 1 and the building structure 2, which not only ensures that the upper and lower interlocking do not detach to maintain connection stability, but also fills the bottom gap to prevent falling and debris intrusion. The pulley assembly includes a load-bearing rail 34 and a load-bearing pulley 33 located in the load-bearing rail 34. The extension direction of the load-bearing rail 34 corresponds to the direction in which the multiple casters 21 are arranged. The comb structure 30 includes an upper tooth 31 and a lower tooth 32 that are inserted into each other. The gaps between the comb structure 30 are perpendicular to the arc-shaped wall 26 to guide the base plate to slide along a preset trajectory with low friction, so as to avoid motion interference or jamming during deformation. Together with the wall panel assembly 5 and the cover plate assembly 19, they form a fully enclosed system, which not only ensures the smoothness of the seismic isolation deformation, but also consolidates the fireproof sealing effect, achieving multiple goals of "deformation adaptation, protective sealing, and stable guidance".
