Description

[Detailed description of the invention] This invention relates to an improved structure of an elevator hoistway.

Conventional elevator hoistways were generally constructed of reinforced concrete cast in a rectangular cross-section.
For this reason, the cost of installing an elevator increases, and when an elevator is installed in an existing building, it requires complicated construction work.

This invention solves the above-mentioned drawbacks and aims to provide an elevator hoistway that can be easily constructed.

An embodiment of this invention will be explained below with reference to FIG.

In the figure, 1 is a load-bearing wall made of the outer wall of the building, 2 is a landing provided on one side of the wall corresponding to the floor of the building, and 2a is a landing 2 provided on the load-bearing wall 1.
The opening, 3, is a stringer made of H-beam steel that is fixed to the load-bearing wall 1 and erected, placed on the side of the load-bearing wall 1 opposite to the landing area 2, and placed on both sides of the opening 2a in the frontage direction; Reference numeral 4 is a U-shaped support in a plane, and a plurality of supports are arranged spaced apart from each other in the vertical direction, and the open ends of the U-shape are fastened to the longitudinal members 3 facing each other; A side shroud plate 6 made of a slate plate is fastened to the stringer 3 and covers one side of the support 4 and is supported on this side. A back shroud made of a slate board supported by the slate board with both edges in the width direction in contact with the edge of the side shroud 5 on the side opposite to the stringer 3; A car is placed in the space formed by the plates 5 and 6, 7a is a guide provided on the car and movably engaged with one side of the stringer 3, and 7b is a guide provided on the car 7. This is a car entrance/exit that faces the opening 2a when necessary.

That is, a hoistway is constituted mainly of the load-bearing wall 1, the support body 4, and the side and back shrouds 5 and 6, and the car 7 moves within the hoistway. Therefore, the hoistway can be constructed easily and with less materials, and the cost of the elevator can be reduced. Further, when an elevator is installed along the outer wall of an existing building, the hoistway can be constructed by particularly simple construction.

It is clear that the same effect can be obtained even if the support 4 in this embodiment is made up of three rods assembled in a U-shape. Also, the sides,
It is obvious that the same effect as in the embodiment shown in FIG. 1 can be obtained even if the back shrouding plates 5, 6 are formed into a single U-shape in cross section.

Figure 2 shows another embodiment of this invention.
In the figure, the same reference numerals as in Figure 1 indicate corresponding parts, and 4 indicates that the open end of the U-shape is directly connected to the load-bearing wall 1 near the stringer 3.
The support body 2b fastened to is a landing device provided in the opening 2a.

That is, in this embodiment as well, the load-bearing wall 1,
Since the hoistway is mainly composed of the side and back shrouding plates 5 and 6, it is clear that the same effect as the embodiment shown in FIG. 1 can be obtained, although detailed explanation will be omitted.

As explained above, this invention supports a load-bearing wall with a landing on one side and supports a stringer that guides the car on the other side, and also connects the U-shaped opening end of the U-shaped support to the load-bearing wall and the longitudinal member. By fixing it to one of the threads and providing side shrouds and back shrouds on this support, the hoistway can be constructed easily and with less materials, reducing the cost of the elevator. Moreover, when an elevator is installed along the outer wall of an existing building, an elevator hoistway that can be constructed with particularly simple construction is realized.
