Description

  The present invention relates to a landing door installation structure for an elevator used in a seismic isolation building having a seismic isolation device in an intermediate part.

  The seismic isolation building has a seismic isolation device in the middle, and in the event of an earthquake, the seismic energy is distributed by allowing relative displacement in the horizontal direction between the upper floor and the lower floor of the seismic isolation device. It is intended to prevent damage to things. In an elevator installation installed in such a base-isolated building, due to a large relative displacement between the floor where the base isolation device is installed (the base isolation layer) and the floor immediately above it (the upper adjacent floor). The hoistway will also be deformed. If the distance between the guide rail and the landing door changes greatly due to the deformation of the hoistway at this time, it becomes impossible for the elevator cars to pass through these floors and passengers to get on and off the elevator cars. Therefore, an elevator installation installed in a base-isolated building is required to have a structure in which the distance between the guide rail and the elevator car in the base isolation floor and the upper adjacent floor is not changed as much as possible (for example, Patent Document 1). reference).

  FIG. 5 is an explanatory diagram of the prior art disclosed in Patent Document 1. In FIG. In this figure, a low-rise part 52 is constructed on a foundation 51, and a high-rise part 54 is constructed above the low-rise part 52 via a seismic isolation device 53. A hoistway 55 penetrating through the inside in the vertical direction is formed in the central portion of the low layer portion 52 and the high layer portion 54. A guide rail 56 is provided inside the hoistway 55, and a car 57 moves up and down in the hoistway 55 along the guide rail 56.

  A lifting column body 58 is provided in the hoistway 55 in the vertical direction centering on the seismic isolation device 53. The lower side of the lifting column body 58 is fixed to the hoistway wall 61 by restraining members 59 and 60. Further, a landing door 62 is provided on the lifting column body 58.

  The lower layer side height H1 and the higher layer side height H2 of the lifting column body 58 centering on the seismic isolation device 53 are equal, and the lifting column body 58 and the lower layer side and higher layer side hoistway wall 61 are The clearances between them are L1 and L2.

When the earthquake occurs, the lifting column body 58 is deformed and the seismic isolation device 53 causes relative displacement between the high-rise part side and the low-rise part side, and the maximum displacement position of the high-rise part 54 is a position indicated by a broken line. Become. The clearances L1 and L2 can be set to a half of the displacement L0 of the high-rise portion 54 at this time.
JP-A-10-88847

  However, when the lifting column body 58 is disposed in the hoistway 55 as shown in FIG. 5, the cross-sectional area of the hoistway 55 must be increased by the amount of the lifting column body 58, Moreover, the floor having the hoistway 55 having such a large cross-sectional area spans a plurality of floors (floors in the range of H1 and H2 in FIG. 5). Therefore, the floor area that can be effectively used in the building is reduced by that amount, leading to a decrease in the value of the building. For this reason, the configuration using the lifting column as in Patent Document 1 is mainly applied only to large-scale buildings, and is not often applied to buildings of medium or smaller scales.

  In the configuration of FIG. 5, the guide rail 56 is supported by the lifting column body 58 over a plurality of floors, but the lifting column body 58 is also deformed so as to follow the deformation of the guide rail 56 at the time of the occurrence of an earthquake. There must be. However, it is difficult to ensure rigidity for enabling such deformation, and there is a problem in that the mounting structure of the lifting column body 58 and other components is complicated.

  This invention is made | formed in view of the said situation, and it can suppress that the floor area which can be used effectively in a building is reduced as much as possible, and can avoid complication of the attachment structure of a component.

  The invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the landing door on the upper adjacent floor of the seismic isolation floor is formed between the landing door and the landing when an earthquake occurs.

  ADVANTAGE OF THE INVENTION According to this invention, it is suppressed as much as possible that the floor area which can be used effectively in a building is reduced, and the landing door of the elevator for seismic isolation buildings which can avoid the complication of the mounting structure of a component is possible. An installation structure can be provided.

  FIG. 1 is a longitudinal sectional view around a hoistway showing a landing door installation structure according to the first embodiment of the present invention, and FIG. 2 is an arrow view taken along line II-II in FIG. In these drawings, a hoistway 2 is formed by a hoistway wall 1, and guide rails 3 and 4 are supported by a support member 5 and disposed in the hoistway 2. A car 6 moves up and down in the hoistway 2 along the guide rail 3, and a counterweight 7 moves up and down in the hoistway 2 along the guide rail 4 in the direction opposite to the car 6. .

  In the building according to this embodiment, the N floor is a seismic isolation layer, and the seismic isolation device 8 is installed on the N floor. Since the relative displacement with the N + 1 floor (upper adjacent floor) increases at the Nth floor when an earthquake occurs, the hoistway wall 1a is shifted outward by the dimension L to ensure a large hoistway area. Further, as is apparent from FIGS. 1 and 2, in consideration of the magnitude of this relative displacement, the spacing between the support members 5 between the Nth floor and the N + 1th floor is the support member in the other floors. It is larger than the interval between the five. Thereby, when the guide rails 3 and 4 between the N floor and the N + 1 floor are deformed when an earthquake occurs, it is avoided that a large stress is applied.

  The landing doors 9 are installed in the elevator halls on each floor, but the installation structure of the landing doors 9 on the Nth floor, which is the seismic isolation floor, and the N + 1 floor, which is the upper adjacent floor, is different from other floors. Yes. Specifically, the lower part of the Nth floor landing door 9 is attached to the floor via the floor-side pivot member 10, and the upper part of the N + 1 floor landing door 9 is attached to the ceiling via the ceiling-side pivotal support member 11. ing. In this embodiment, a universal joint that can rotate in any direction on three-axis coordinates is used as the floor-side pivot member 10 and the ceiling-side pivot member 11, and the mounting position is a landing. It is the center part of the door 9 (refer FIG. 2).

  A plurality of the support members 5 described above are attached to the guide rails 3 and 4, but as shown in FIG. 1, the positions of the floor side support member 10 and the ceiling side support member 11 are the attachment positions of the support member 5. And almost the same height.

  A shaft support member 12 is attached to the upper part of the Nth floor landing door 9, and a shaft support member 13 is attached on the guide rail 3 having the same height as the mounting position of the shaft support member 12. One end side and the other end side of the first coupling member 14 are pivotally supported on the members 12 and 13, respectively. Further, a shaft support member 15 is attached to the lower part of the landing door 9 on the N + 1 floor, and a shaft support member 16 is attached on the guide rail 3 having the same height as the mounting position of the shaft support member 15. One end side and the other end side of the second coupling member 17 are pivotally supported on the materials 15 and 16, respectively.

  A plate member 18 is attached to the lower part of the front side of the landing door 9 on the (N + 1) th floor, and its front end portion is slidable in a groove portion 19 formed in the floor portion. As a result, even if the relative displacement between the Nth floor and the (N + 1) th floor becomes large and a gap G occurs when an earthquake occurs, the plate member 18 always covers this gap G. In FIG. 1 and FIG. 2, for simplicity of explanation, the plate member 18 is illustrated as being attached only to the lower part of the landing door 9. Therefore, consideration is given so that there is no gap between the side and the ceiling. Moreover, this plate member 18 can be attached not only to the floor of the (N + 1) th floor but also to the ceiling of the Nth floor.

  Next, the operation of the first embodiment configured as described above will be described. During normal times, that is, when there is no earthquake, there is almost no relative displacement between the Nth floor and the (N + 1) th floor, and therefore the guide rails 3 and 4 extend straight up and down in the hoistway 2 without deformation. It is in a state.

  However, when an earthquake occurs, the amount of relative displacement between the Nth floor and the (N + 1) th floor increases as shown in FIGS. 1 and 2 due to the action of the seismic isolation device 8, and the guide rails 3 and 4 are also positioned at normal times. Displaces horizontally in the horizontal direction. At this time, as described above, the distance between the support members 5 between the Nth floor and the N + 1th floor is larger than the distance between the support members 5 at the other floors. It can be avoided that a large stress is applied to the guide rails 3 and 4 between the two.

  When the guide rail 3 is displaced in the horizontal direction, the upper part of the Nth floor landing door 9 and the lower part of the N + 1 floor landing door 9 are pushed or pulled by the first coupling member 14 and the second coupling member 17, respectively. It pivots about the side support member 10 and the ceiling side support member 11. At this time, the relative displacement between the Nth floor and the N + 1th floor occurs in all directions in the front, rear, left, and right directions of each landing door 9, but the floor side pivot member 10 and the ceiling side pivot member 11 have universal joints. Since it is used, each landing door 9 can smoothly rotate in any direction. Since the positions of the floor-side pivot member 10 and the ceiling-side pivot member 11 are substantially the same as the mounting position of the support member 5, as described above, the floor-side pivot member 10 and the ceiling-side pivot The distance in the horizontal direction between the support member 11 and the support member 5 facing each other does not change so much as before the occurrence of the earthquake.

  However, although the amount of relative displacement in the vertical direction between the guide rail 3 and each landing door 9 is not necessarily small, the first coupling member 14 and the second coupling member 17 are supported by the shaft support members 12, 13, Since it is pivotally supported by 15, 16, it can be absorbed by the rotation of the first coupling member 14 and the second coupling member 17.

  As described above, in the configuration shown in FIGS. 1 and 2, even if the guide rails 3 and 4 are greatly deformed by the relative displacement between the N floor and the N + 1 floor due to the action of the seismic isolation device 8 when an earthquake occurs, Each of the landing doors 9 on the floor is pivoted about the floor-side pivot member 10 and the ceiling-side pivot member 11 and changes its posture so as to follow the horizontal displacement of the guide rails 3 and 4. Therefore, the distance between the guide rail 3 and the car 6 can be prevented from greatly fluctuating, and the car 6 can pass between the Nth floor and the N + 1th floor without hitting the landing door 9. Further, since it is avoided that a large force is applied to each landing door 9 due to the posture change at this time, the opening and closing operation of the door is performed without any trouble, and passengers between the car 6 and the elevator landing are not affected. Getting on or off is not hindered.

  Furthermore, in this embodiment, the plate member 18 is attached to the lower part of the front (and side) side of the (N + 1) th floor landing door 9 so as to cover the gap G generated by the rotation of the landing door 9. It is possible to prevent an accident where a passenger waiting for an elevator in front of the vehicle falls into the gap G.

  The configuration shown in FIGS. 1 and 2 does not use a lifting column unlike the conventional configuration shown in FIG. 5, so there is no need to increase the area of the hoistway 2 and it is effective in the building. There is no reduction in available floor space.

  Further, the constituent members are also a few such as the floor-side pivot member 10, the ceiling-side pivot member 11, the first coupling member 14, the second coupling member 17, the pivot members 12, 13, 15, 16 and the like. Yes, and its mounting structure is not complicated. Therefore, the configuration shown in FIGS. 1 and 2 can be used not only for a new building but also for an existing building having a seismic isolation structure. It can be adopted regardless of the case.

  FIG. 3 is a longitudinal sectional view around a hoistway showing a landing door installation structure according to a second embodiment of the present invention, and FIG. 4 is an arrow view taken along line IV-IV in FIG. 3 and 4 is different from FIGS. 1 and 2 in the upper mounting structure of the Nth floor landing door 9 and the lower mounting structure of the N + 1 floor landing door 9. In other words, a shaft support member 20 is attached to the lower part of the landing door 9 on the N + 1 floor, and a shaft support member 21 is attached on the guide rail 3 having the same height as the mounting position of the shaft support member 20. One end side and the other end side of the coupling member 22 composed of one member are supported on the members 20 and 21, respectively.

  Further, the lower part of the (N + 1) th floor landing door 9 and the upper part of the Nth floor landing door 9 are connected by a connecting member 23. Accordingly, the upper part of the Nth floor landing door 9 is coupled to the guide rail 3 via the connecting member 23 and the coupling member 22. Here, at the upper end of the connecting member 23, for example, a long hole is provided in the vertical direction, and a bolt member or a pin member fixed to the lower part of the landing door 9 on the N + 1 floor is inserted into the long hole. The upper end of the connecting member 23 and the lower part of the (N + 1) th floor landing door 9 are attached.

  Next, the operation of the second embodiment configured as described above will be described only for parts different from the first embodiment. Since the operation of other parts is the same as that of the first embodiment, description thereof is omitted.

  When the guide rail 3 is displaced in the horizontal direction, the lower part of the (N + 1) th floor landing door 9 is pushed or pulled by the coupling member 22 and thus rotates around the ceiling side support member 11. Further, the upper part of the Nth floor landing door 9 is also pushed or pulled by the connecting member 23, and thus rotates around the floor side support member 10.

  In this way, when the N + 1 floor landing door 9 and the Nth floor landing door 9 rotate about the ceiling side pivot support member 11 and the floor side pivot support member 10, respectively, the landing is performed according to the pivoting operation at this time. Since the distance in the vertical direction between the doors 9 varies, the landing doors 9 are likely to collide or pull each other. However, as described above, since a long hole is used for attachment between the upper end of the connecting member 23 and the lower part of the (N + 1) th floor landing door 9, it is possible to absorb the variation in distance in the vertical direction at this time. It is possible to smoothly change the posture of each landing door 9 according to the deformation of the guide rail 3.

  Therefore, as in the case of the first embodiment, even if the guide rails 3 and 4 are greatly deformed due to the relative displacement between the Nth floor and the N + 1th floor due to the action of the seismic isolation device 8 when an earthquake occurs, these floors Each of the landing doors 9 can rotate around the floor-side pivot member 10 and the ceiling-side pivot member 11 and change its posture so as to follow the horizontal displacement of the guide rails 3 and 4. It is possible to prevent the distance between the guide rail 3 and the car 6 from fluctuating greatly.

  However, as is clear from a comparison between FIG. 3 and FIG. 1, the turning radius of the upper part of the Nth floor landing door 9 is between the floor side support member 10 and the support member 20 in FIG. 3. In contrast to the distance, in FIG. 1, it is a smaller distance between the floor side support member 10 and the support member 12. Therefore, the amount of variation in the distance between the guide rail 3 and the car 6 can be made smaller in the first embodiment than in the second embodiment. On the other hand, since the number of constituent members in the second embodiment is smaller than that in the first embodiment, it can be said that the second embodiment is more advantageous in terms of cost.
