Description

  The present invention relates to a building in which an elevator apparatus including a basket and a counterweight connected via a rope is installed over the upper and lower levels.

Conventionally, in this type of building, a drive type elevator device that uses a counterweight is installed, and the cage and counterweight are attached to both ends of the rope hung on the hoisting drum, and the hoisting is performed. In some cases, the cage and the counterweight are formed to move relative to each other in the up-down direction in the elevator shaft as the drum rotates (see, for example, Patent Document 1 and Patent Document 2).
Patent Document 1 describes a building in which an elevator shaft composed of a partition wall made of a glass screen is provided in an atrium (blowout space). This building is configured so that the cage that moves up and down the elevator shaft and the counterweight can be seen through from the atrium side.
Patent Document 2 describes an elevator apparatus in which a counterweight is attached to a movable pulley and suspended in order to secure a device installation space in an inner space (upper end portion) of an elevator shaft surrounded by a partition wall. Has been. This building is designed so that the lifting and lowering dimensions of the counterweight are reduced by the difference in the roping ratio between the cage and the counterweight, and the range where the counterweight does not move up and down is set at the upper end of the elevator shaft. The range can be used as the equipment installation space.

According to the building described in Patent Document 1 described above, an elevator shaft that is normally closed and cannot be seen from the outside has a feature that an open design feeling can be obtained by being configured to be seen through. However, the cages, counterweights, and the complicated appearances of the ropes, rails, cables, etc. associated with them are too obvious, which is not preferable from the viewpoint of aesthetics.
According to the building described in Patent Document 2 described above, the elevator shaft itself has a closed structure. For example, as in Patent Document 1, a partition wall is formed of a glass screen or the like and can be seen through an atrium. Even in this case, there are various equipment installed in the moving pulley and the equipment installation space in addition to the cage and counterweight, and the related ropes, rails and cables, so it is still aesthetic. There was an unfavorable problem from the point of view.

  Accordingly, an object of the present invention is to provide a building that solves the above-described problems and can provide an open design feeling and good aesthetics in the surrounding environment including the elevator apparatus.

A first characteristic configuration of the present invention is a building in which an elevator apparatus including a cage and a counterweight connected via a rope is installed over the upper and lower tiers, and at least a ventilated space leading to the upper and lower tiers is provided. It is formed in a part of the hierarchy, an elevator hall part is arranged facing the blowout space, a boundary part between the elevator hall part and the blowout space, and the cage includes the elevator hall part It is formed in a state where it can be seen from each other with the blowout space, the blowout space is disposed below the hoistway of the counterweight, and the elevator apparatus is configured so that the balance is in the blowout space. The weight is in a place where only the basket is moved up and down without moving up and down.

According to the first characteristic configuration of the present invention, the blowout space leading to the upper and lower layers is formed in at least a part of the hierarchy, and an elevator hall portion is arranged facing the blowout space, and the elevator hall portion And the blow-off space are formed so that they can be seen from each other. Therefore, when there is no cage on the floor, the blow-off space side from the elevator hall and the lift-hole portion from the blow-off space are provided. Each can be seen through, and an open design feeling that does not feel the presence of the elevator apparatus can be obtained. Similarly, the cage is also formed so that the elevator hall and the ventilated space can be seen from each other, so even if the cage exists on the floor, the visibility of the elevator hall and the ventilated space is mutually visible. Can be ensured, and an open design feeling can be obtained.
Furthermore, a person on the basket can see the elevator hall side and the atrium space side, and can enjoy a changed scenery as compared with a conventional closed car. In addition, as the basket is raised and lowered, it is possible to obtain a sensation of moving in the space in a floating state.
Moreover, the open design feel spreads between each level that communicates with the ventilated space in addition to the two-dimensional spread of each level, and three-dimensional continuity between each level and the ventilated space is obtained. It becomes easy to be done.
Therefore, when looking at each level from the atrium space side, it seems that each level and basket floats in the space. When looking at the atrium space from each level side, it is as if your own viewpoint position is in the space. You can feel as if you are floating, and you can get an inside view with a unique feeling of floating.
On the other hand, in the elevator space, in the blowout space, the balance weight is not moved up and down, and only the basket is moved up and down, so the presence of a balance weight from the elevator shaft portion in the blowout space. It can be lost. Therefore, it is difficult to impair the unique floating feeling as described above.
Further, in order to prevent the counterweight from appearing in the blowout space, for example, a method of roping so that the balance weight moves up and down only in a range above the blowout space, in addition to a normal elevator shaft, In addition to the counterweight, the existence of ropes, rails, pulleys, etc. related to it, in addition to the counterweight, can be achieved by adopting a method that links and installs another shaft where only the counterweight moves up and down. It can be eliminated from the elevator shaft portion in the blowout space. Therefore, the aesthetics around the elevator shaft portion can be improved, and at the same time, the above-mentioned open design feeling can be realized in a more preferable state.
As a result, an open design feeling and good aesthetics can be obtained in the surrounding environment including the elevator apparatus.

  According to a second characteristic configuration of the present invention, the roping of the elevator apparatus is set so that only the car moves up and down in the blowout space by suspending the car and the counterweight with different roping ratios. There is somewhere.

According to the second characteristic configuration of the present invention, it can be realized by a simple configuration in which the roping ratio is different in setting so that only the cage moves up and down in the blow-out space, and the object is economical. Can be achieved.
In addition, since the basket and the counterweight can be positioned in the same elevator shaft and can be realized with a configuration that adds a movable pulley, maintenance such as inspection and repair is not time-consuming.
Therefore, not only the initial cost but also the running cost can be reduced.

  The third characteristic configuration of the present invention is the presence of the counterweight from below at the boundary between the elevator shaft portion in the blow-out space and the elevator shaft portion in which the cage and the counterweight move up and down. There is a blindfold that makes it difficult to see.

  According to the third characteristic configuration of the present invention, when the elevator shaft portion is looked up from the blow-off space or a layer adjacent thereto, the upper view is blocked by the blindfold portion, and the presence of the counterweight is confirmed. It can be difficult to see. Therefore, it is possible to conceal a realistic backstage, and it is possible to make it appear as if it is lifted up and down with only a basket without a counterweight.

  Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of a building according to the present invention. Building B is composed of a plurality of layers, and an atrium (atrium space) 1 is formed over a plurality of layers in the lower layer portion. .
In addition, an elevator device 2 that extends across the entire upper and lower levels of the building B is provided at the planar position of the atrium 1.
On each floor of the ventilated floor Ba where the atrium 1 is formed, an elevator hall portion 3 is arranged facing the atrium 1.

In each floor of the above-described air-blowing layer Ba, the portion surrounding and facing the atrium 1 avoids opaque walls so as not to block the line of sight as much as possible, and mainly includes handrails 4 and transparent glass walls (not shown). Thus, each floor and the atrium 1 can be seen through each other while preventing fall (see FIG. 2).
The same applies to the elevator hall 3, and as shown in FIG. 2, the elevator outer door 5A serving as the boundary 5 between the elevator hall 3 and the atrium 1 and the decorative walls 5B located on the left and right thereof are made of transparent glass. The elevator hall 3 and the atrium 1 and the front and rear floors sandwiching the atrium 1 are not easily obstructed and are visible from each other.

As shown in FIG. 1, the elevator apparatus 2 includes a cage 2B and a counterweight 2C linked via a rope 2A.
The elevator device 2 can be lifted and lowered by rotating the hoisting drum 2D with a motor while the rope 2A is hung on the hoisting drum 2D.
Further, in this embodiment, by using the movable pulley 6, the roping ratio between the basket 2 </ b> B and the counterweight 2 </ b> C is made different, and as shown in the figure, the lifting / lowering stroke H <b> 1 of the counterweight 2 </ b> C is It is set to be 1/2 of the 2B lifting stroke H2. And while the raising / lowering stroke H2 of the cage 2B extends over all levels, the raising / lowering stroke H1 of the counterweight 2C is set in the upper layer portion.
In the elevator shaft portion S1 located above the atrium 1, both the cage 2B and the counterweight 2C are raised and lowered. In the elevator shaft portion S2 located in the atrium 1, only the cage 2B is raised and lowered. To do.
Accordingly, a cage rail R2 serving as a guide for the cage 2B is installed across the upper and lower elevator shaft portions S, while a weight rail R1 serving as a guide for the counterweight 2C is also provided on the upper elevator shaft portion S1. is set up. In addition to the rails R, the rope 2A, cable (not shown), the movable pulley 6 and the like are provided as accessory parts provided in the elevator shaft portion S. The elevator shaft portion S2 is provided with a minimum number of rails R for raising and lowering the cage 2B, a rope 2A, and a cable (not shown).
Moreover, in the atrium 1, the said rail R is installed in the back side of the decorative wall 5B of the said boundary part 5 (refer FIG. 2).
The cage 2B includes a cage body 9 having a rectangular box shape, and includes a peripheral surface portion including an elevator inner door 9a that simultaneously opens and closes the elevator outer door 5A while being stopped at a stop position on each floor. 9b is formed of transparent glass.
Therefore, even in a state where the basket 2B is stopped, it is difficult to obstruct the field of view between the elevator hall portion 3, the atrium 1, and the floors before and after the atrium 1, and an open atmosphere can be maintained. In addition, the field of view from within the basket 2B can be secured over the entire circumference.

  Incidentally, a plate-like projecting portion (corresponding to a blindfold) 10 projecting toward the center of the shaft at the boundary between the elevator shaft portion S1 located above the atrium 1 and the elevator shaft portion S2 located on the atrium 1 is a floor surface. (See FIG. 1), so that the presence of the counterweight 2A is difficult to see from below.

According to the building B of the present embodiment, the elevator hall unit 3 can be seen through the atrium 1 side, and the atrium 1 through the elevator hall unit 3 and the floors on both sides sandwiching the atrium 1 can be seen through, respectively. An open design feeling that does not feel the presence of 2 is obtained.
Moreover, the open design feeling extends in addition to the planar spread for each level, and also spreads between each level communicating with the atrium 1, so that the three-dimensional continuity between each level and the atrium 1 is obtained. It becomes easy to be done.
Therefore, when each level is viewed from the atrium 1 side, it is felt that each level is floating in the space, and when each level is viewed from the level (or from the level side through the atrium 1 When looking at each level), you can feel as if your point of view is floating in the space, and you can get an introspection with a unique floating feeling.
And in the atrium 1, since the counterweight 2C does not move up and down, but only the cage 2B moves up and down, it is difficult to impair the peculiar floating feeling as described above.
As a result, an open design feeling and good aesthetics can be obtained in the surrounding environment including the elevator apparatus 2.
