Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator car corresponding to displacement of an elevator shaft caused by a shake such as an earthquake.
[0002]
[Prior art]
One method of retrofitting existing buildings is to add seismic isolation structures. In this construction method, axial support materials are placed on existing columns on the intermediate floor, the columns are temporarily separated from each other, the columns are connected to the separated intermediate parts by seismic isolation devices such as seismic isolation rubber, and then the axial force support is performed. It is a construction method that removes materials, and in the renovation, the construction scope is a seismically isolated floor and can be limited only to the periphery of the pillar, so there is an advantage that construction can be performed without hindering daily use of the building .
[0003]
And in this construction method, after making the column a seismic isolation structure, a seismic isolation slit is formed in the wall etc. along the line of the column cutting level, so that the top and bottom of the building are completely separated, and only the seismic isolation device is used. Support building loads.
[0004]
As shown in FIG. 6 (a), a building subjected to this type of renovation is also provided with a seismic isolation slit 2a on a wall 2 constituting the elevator shaft 1. In the figure, reference numeral 3 is an intermediate floor column, 4 is a seismic isolation device interposed between the columns 3, and 5 is an elevator car that moves up and down in the shaft 1.
[0005]
[Problems to be solved by the invention]
In a building with the above seismic isolation structure, the building is relatively displaced in the horizontal direction at the position of the intermediate floor as shown in FIG. There may be a case where the car 5 passes or stops through the intermediate floor or is stopped by an emergency stop device. In such a case, the relative displacement may cause the wall 2 of the shaft 1 to collide with the car 5 and damage it.
[0006]
In order to avoid such fears, the shaft 1 on the intermediate floor is widened by shifting the wall 2 by the assumed maximum displacement w as shown by the broken line in FIG. It is necessary to take one of the measures to replace the car 5 with a smaller vertical and horizontal dimension corresponding to the maximum displacement.
[0007]
However, in the case of the former widening work, the floor area used for the building such as the elevator hall is reduced by the wide shaft 1, and the construction burden is also increased. This type of widening work is not possible in the case of an old building.
[0008]
In addition, when the latter is replaced with a volume-reduced type car, the capacity of the car is reduced, the transportation capacity is reduced correspondingly, and the mechanical equipment in the shaft 1 corresponds to the downsized car. Must be replaced with a new structure, which still requires significant renovation.
[0009]
The present invention solves the above-mentioned problems, and its purpose is to have the same volume as before the seismic isolation repair, and to reduce the collision impact due to the relative displacement at the time of the earthquake as described above, thereby damaging the car. The present invention also provides an elevator car suitable for a building subjected to seismic isolation repair, which can prevent accidents caused by personal injury.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a rectangular parallelepiped car composed of a floor, a ceiling, and four walls , each of which is divided into a vertical dividing line, Dividing into a plurality of panels in which the ceiling and floor constituent parts that are continuous with the constituent parts are integrated , and the width of the car parts orthogonal to each other between the ceiling constituent parts of the adjacent panels and the floor constituent parts. And connecting the constituent parts of the walls on both sides in the depth direction of adjacent panels so that they can move relative to each other in the width direction. The constituent parts of the walls on both sides in the direction are coupled so as to be relatively movable in the depth direction, and the panels on both sides in the width direction and the panels on both sides in the depth direction are connected at the upper position and the lower position of the car. And connected by a connecting member provided with cushioning material, the connecting member is contracted and displaced in a direction in which the panel to each other to be connected by the connecting member is adjacent, elongated and displaced in a direction between the panel is separated, the buffer The elevator car according to claim 1, wherein the material absorbs an impact when the connecting member contracts and generates a repulsive force that extends the connecting member .
[0011]
As described above, in the present invention, when the upper and lower walls constituting the shaft are relatively displaced, the wall of the car collides with the wall, but the shock at the time of the collision is alleviated by the buffer material. On the other hand, the panels move in the moving direction of the wall via the expansion joint, thereby preventing the car from being damaged by the impact pressure and at the same time protecting the passengers inside from the impact. Furthermore, since the expansion joint is provided in two directions, that is, a depth direction and a width direction perpendicular to the car, the car can be expanded and contracted with respect to all horizontal swings.
[0012]
Moreover, in this invention, the said expansion joint can comprise an expansion joint with a comparatively simple structure by connecting the said panels in a nested manner.
[0013]
Further, the connecting member includes a pair of pistons, a cylinder inserted through both pistons on both sides, and a cushioning material filled in a gap of the cylinder, and the pair of pistons are respectively connected to a panel to be connected. It may be connected .
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Since the structure of the elevator shaft and the like are exactly the same as the structure shown in FIG. 6, the same portions are denoted by the same reference numerals, and only newly added portions are described using new reference numerals.
[0015]
FIG. 1 shows a car 10 according to the present invention. The car 10 is guided so as to be able to be raised and lowered along a fixed guide 12 provided on the inner wall of the elevator shaft 1 and can be lifted and lowered by a wire rope 16. A suspended box-shaped car body 18 and a connecting member 22 for connecting upper ends and lower ends of connecting bars 20 fixedly arranged vertically on both sides of the car body 18 are provided.
[0016]
The connecting member 22 includes a pair of pistons 24 each having one end fixed to the upper and lower ends of the connecting bar 20, a cylinder 26 inserted through both pistons 24 on both sides, and a cushioning material 28 filled in the gap of the cylinder 26. It is made up of. The connecting bar 20 and the connecting member 22 are not only provided above and below in the width direction of the car body 18, but also arranged in the depth direction above and below although not shown.
[0017]
FIG. 1 shows a state where the car 10 passes through the seismic isolation device installation floor of the shaft 1 or is stopped on the seismic isolation device installation floor, and the wall 2 of the shaft 1 has the seismic isolation slit 2a. The fixed guides 12 that are separated from each other through the wall 2 and are disposed in the wall 2 are also joined to each other at the same level by a pin joint 12a.
[0018]
FIG. 2 shows the car body 18. As shown in FIG. 1A, the car body 18 is divided into a front panel 30, a rear panel 32, a pair of front corner panels 34, and a pair of rear corner panels 36. These members are combined together by the connecting member 22.
[0019]
Each of the panels 30 to 36 is made by integrating a floor, a wall, and a ceiling, and the front panel 32 has a front center with an opening 32a into which a door 38 (see FIG. 1) is assembled. It is a shape having a substantially U-shaped cross section in which a floor and a ceiling are integrally formed above and below a wall.
[0020]
The back panel 34 has a substantially U-shaped shape in which a floor and a ceiling are formed above and below the back center wall.
[0021]
The front corner panel 36 has a floor and a ceiling integrated above and below a front wall portion formed by cutting out an opening portion corresponding to the opening portion 32a on one side and a front side wall formed orthogonal thereto. Shape.
[0022]
The rear corner panel 38 has a shape in which a floor and a ceiling are integrated on the upper and lower sides of a rear wall and a rear side wall formed orthogonal thereto.
[0023]
And these each member is combined so that expansion / contraction is possible via a telescopic expansion joint part.
[0024]
That is, the ceilings and floors of the front and back panels 30, 32 are overlapped with each other and are slidably connected. In addition, the front and rear corner panels 34 and 36 have their side walls, floor and ceiling overlapped with each other and are slidably connected to each other, and each front wall portion and rear wall portion and each floor and ceiling are respectively connected to each other. The front and rear panels 30 and 32 are overlapped and slidably connected to each other.
[0025]
Therefore, as shown in FIG. 2B, the maximum size of the assembled state of the expansion member is, for example, three times the floor area of the front panel 30. Further, the minimum area is reduced to a size comparable to the floor area of the front panel 30.
[0026]
Note that in FIGS. 2B and 2C described above, the overlap is not taken into consideration, so that the shape is extremely deformed. Therefore, in actual design, the expansion / contraction dimensions corresponding to the maximum horizontal displacement during an earthquake and the overlap allowance in the nesting portion of each panel corresponding to this are set, and the volume of the normal state is set by the connecting member 22 described above. Retained in shape.
[0027]
Further, in the normal state, the opening is opened in the front corner panel 36 in FIG. 5B, but the dimensions are set so as not to actually open.
[0028]
Next, a case where a swing having a predetermined seismic intensity occurs while the car having the above configuration passes through the seismic isolation device installation floor of the shaft 1 or stops will be described with reference to FIGS.
[0029]
First, as shown in FIG. 3 (a), the volume of the car body 18 is maintained at the maximum, and has a normal cross-sectional area corresponding to the cross-sectional area of the shaft 1, so that passengers can be accommodated. It can be accommodated. In the figure, reference numeral 40 denotes a hall side door provided in the opening 42 of the elevator hall.
[0030]
From this state, when horizontal displacement occurs in the width direction (XX) direction and the upper and lower sides of the wall 2 are shifted to the left and right as shown in FIG. One side wall is pressed, and the upper wall 2 presses the other side wall. By this pressing force, the left and right side walls are reduced in width so as to be close to each other in a nested manner as indicated by the arrows while reducing the connecting portion 22. When the connecting member 22 is reduced, the cushioning effect of the cushioning material 28 (see FIG. 1) provided inside reduces the impact of the collision, so that a passenger in the main body can be injured during an earthquake. To prevent.
[0031]
Further, as shown in FIG. 3B, even when displacement in the depth direction (Y-Y) direction occurs, the front and rear wall surfaces shrink in a nested manner as shown in FIG. A collision impact is prevented in advance by a buffering effect when the connecting member 22 to be joined is reduced.
[0032]
Furthermore, since the main body 18 can be expanded and contracted in each direction, not only in the X and Y directions, it is needless to say that the main body 18 can be reduced in response to relative displacements in all horizontal directions.
[0033]
Although omitted in the figure, in order to prevent the influence on passengers due to the relative displacement of the wall and floor of the main body 18, it is preferable to dispose a telescopic interior floor material and an interior wall material. In addition, when the passengers are fully seated, even if the main body is reduced due to this type of relative displacement, the amount of displacement is such that the passengers actually come into contact with each other.
[0034]
Shaking blind, when returning again to the upper and lower walls 2 each other straight, the resilience of the cushioning material 28 provided on the connecting member 2 2, the body 18 is spread on the original volume, typically shown in FIG. 3 again (a) Return to the state.
[0035]
【The invention's effect】
As is clear from the above description, in the elevator car according to the present invention, it is not necessary to widen the shaft width of the seismic isolation device installation floor or to replace it with a small car, so the number of construction work, Since there is no need to replace the equipment in the shaft, and the car only needs to be replaced with the structure of the present invention, it is possible to carry out without reducing the available floor area around the shaft.
[0036]
In addition, since the car of the present invention can be designed with the same volume as before the seismic isolation of the building, there is an advantage that the transport capacity is not reduced.
