Abstract

PURPOSE:To narrow an opening between juxtaposed elevators so as to decrease elevator space occupying a building by parallelly providing two or more lift paths each partitioned by an intermediate beam folded and formed into a crank shape, and mounting guide rails in the vicinity of a fold part of the beam. CONSTITUTION:Two lift paths 1, 1a are parallelly provided and partitioned by an intermediate beam 30 folded almost at a right angle at a central part in the lengthwise direction and thereafter again at a right angle in an opposite direction and formed into a crank shape. Guide rails 6b, 6c, 7b, 7c are mounted in the vicinity of the folded parts and weights 5, 5a or hydraulic jack are arranged at space parts 34, 35 formed by the folded parts. By this constitution, width between guide rails 6, 6b and 6c, 6a in a side of both cages 4, 4a can be substantially decreased, and elevator space, occupying a building, can be deceased by shortening opening width W of an elevator.

A small hole is made in each of the hoistways (1) and (la) along c) (the figure shows the case where the weight side guide rail (7a) is attached to the intermediate beam (3)).

Among the car side guide rails (6) to (6C) and the weight side guide rails (7) to (7C), one of the guide rails (6), (8a), (7), and (7a) is, for example, the sixth As shown in Figure (a), the hoistway (1), (la
) around! ! (2) is fixed with a clip or the like (10) to a bracket (8) attached to the hoistway (L), <la) so as to slightly protrude inside.

Also, the other guide rail (8b), (Be) (7

from the intermediate beam (3) to the hoistway (1) in such a way that it does not come in contact with (4a) or the intermediate beam (3) and cause any trouble.

It is necessary to protrude by h within (la) (Jikko Sho 62

[Problems to be Solved by the Invention] As described above, the conventional guide rail bracket (9) fixed to the intermediate beam (3) is
a) Hoistway (1) so that there is no problem in going up and down.

(la), the hoistway opening W1 becomes wider, which causes the problem that the elevator space occupied in the building becomes larger. This becomes more noticeable as the number of elevators installed in parallel increases.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to obtain an elevator system that can narrow the openings of elevators installed in parallel, and thus can reduce the space occupied by the elevators in a building.

[Means for Solving the Problems] An elevator system according to the present invention has two or more hoistways arranged in parallel, and a part or all of an intermediate beam that partitions each hoistway is approximately central in the length direction. After being bent at a right angle, it is bent again at a right angle in the opposite direction to form a crank shape, and a guide rail is attached near this bent portion.

[Function] A weight or hydraulic jack is arranged in the space formed by the bending part of the intermediate beam, and guides the elevator car, weight, plunger, etc., which is raised and lowered by a guide rail attached to the peripheral wall and the intermediate beam.

[Embodiment] FIG. 1 is a plan sectional view of an embodiment of the present invention, and FIG. 2 is an enlarged plan view of the main part thereof. Note that this is the same as the conventional example shown in Fig. 5.
Or corresponding parts are given the same reference numerals and their explanations are omitted. In the figure, (30) is an intermediate beam made of, for example, H-beam steel, the central part of which is bent at right angles to have a bent part (31), and the straight parts (31) extending in the opposite direction on both sides. 32
), (33) are formed, and the bent part (31) and the straight part (32) and the bent part (31) and the straight part (33) form a space part (34), respectively.
(35) is formed. (3B) is the intermediate beam (3
0) on the hoistway (1) side, the bracket is fixed to the bent part (31) and the straight part (33), and (37) is the bent part (37) on the hoistway (la) side of the intermediate beam (30). Department (
31) and a bracket fixed to the straight part (32),
Each guide rail (eb

(6c), (7b), and (7c) are installed. And the weights (5) and (5a) are the space part (
34), a basket (4) housed in (35),
(4a), and the weight side guide rail (7),
(7b), and a space (34) along (7a) and (7c).

(35) Go up and down inside. The bracket (8) shown in FIG. 6(a) is used as the bracket fixed to the peripheral wall (2).

In the present invention, since the intermediate beam (30) is configured as described above, the width W2 between the car side guide rails (8b) and (Be) is significantly larger than the width W3 between the conventional car side guide rails. It can be made shorter, and therefore the opening width W of the elevator can be made narrower.

In addition, conventionally, in the machine room provided above the hoistway (1), (la), a machine platform for mounting the hoisting machine, etc., was provided for each hoistway (1), (la). However, according to the present invention, the opening width W of the elevator can be narrowed as described above, so one machine stand (12) can be placed above both hoistways (1) and (la) as shown in FIG. The hoisting machines (13) and (1) of the respective hoistways (1) and (la)
3a), hoisting machine (14), (14a), etc. can be mounted and used for both purposes. As a result, not only can the space in the machine room (11) be reduced, but also one machine stand (one
2) can be used for the two hoistways (1) and (la), so costs can be reduced.

FIG. 4(a) is a plan sectional view of another embodiment of the present invention, FIG. 4(b)
is a longitudinal sectional view thereof. In this example, the present invention was implemented in a hydraulic side plunger type elevator.

(35) Go up and down inside. (1B) is a hydraulic jack (15

In this example, the intermediate beam (

5) and (15a), the opening width of the elevator can be narrowed.

In the above description, the present invention is applied to an elevator system in which two hoistways are installed in parallel, but the present invention can also be implemented in a case in which two or more hoistways are installed in parallel.

Further, although the guide rail is attached to the peripheral wall and intermediate beam using the illustrated brackets and clips, the present invention is not limited to this, and other means may be used.

[Effects of the Invention] The present invention provides two or more hoistways in parallel, and an intermediate beam that partitions each hoistway is bent at a substantially right angle at the center in the length direction, and then bent again at a right angle in the opposite direction. It is bent to form a crank shape, a guide rail is attached near the bent part, and a weight or hydraulic jack is placed in the space formed by the bent part, so the width between the guide rails on both ζ sides can be reduced. can be made significantly shorter than in the past, and as a result, the opening width of the elevator can be narrowed, making it possible to reduce the space occupied by the elevator in the building.

In addition, since the opening width of the elevator has been narrowed, the hoisting machine stand and the machine stand on which the hoisting machine is mounted can be used as two hoistways, which not only reduces the space in the machine room but also reduces costs. An additional effect of reducing the amount of water is also obtained.
