Problems solved by technology

[0005] The object of the present invention is to provide a parallel installation type elevator installation in which a passenger elevator and an emergency elevator are arranged in parallel. In this parallel installation, even if the passenger elevator and the emergency elevator are installed in parallel, The eddy current sound generated when the car of the passenger-carrying elevator is raised and lowered can improve the situation of declining service quality for passengers

Embodiment Construction

[0032] based on the following figure 1 The standard floor of the emergency elevator shown is a description of the first embodiment of the parallel installation type elevator equipment of the present invention.

[0033] In the juxtaposed elevator installations of the present invention, a shared hoistway space 2 is formed in a building 1, and an emergency elevator 3 and a passenger elevator 4 are arranged side by side in the shared hoistway space 2.

[0034] The shared hoistway space 2 is divided by a fire-resistant wall 5 , and inside the space, the hoistway space 3A of the emergency elevator 3 communicates with the hoistway space 4A of the passenger elevator 4 . Furthermore, between the hoistway space 3A and the hoistway space 4A in the common hoistway space 2, intermediate beams 2S are provided at a plurality of positions in the height direction. In addition, an entrance 7 communicating with the elevator hall space 6 of the emergency elevator 3 is formed on the fire-resistan...

Abstract

The invention provides a elevator device arranged in parallel, even arranged passenger elevator and emergency elevator in parallel, also can repress the passenger elevator generating vortex sound during normal lifting running, can improve coniditon of degradation of quality of service for panssengers. In the invention, lifting passage space 3A of the emergency elevator and lifting passage space 4A of the passenger elevator is arranged in a sharing lifting passage space 2 composed by fire-protecting wall 5, 5A, 5B. According to the structure, having no use for arranging interval fire-protecting wall between two lifting passage space 3A, 4A, the passenger elevator can use the two lifting passage space 3A, 4A when lifting, so can repress elevator car generating vortex sound during lifting ina strait space. Moreover, because can repress vortex sound, the elevator car can lift with high speed, thereby impossible cause degradation of quality of service for panssengers.

Description

technical field [0001] The present invention relates to a side-by-side elevator equipment and its operation method in which a plurality of elevators are arranged adjacent to each other, in particular to a side-by-side elevator equipment and its operation method in which a passenger elevator and an emergency elevator are arranged adjacent to each other . Background technique [0002] In general, emergency elevators are obliged to be installed in buildings whose height and floor area meet certain conditions. In this emergency elevator, it is necessary to adopt a fire-resistant wall made of non-combustible materials and a fire door with the function of blocking flames and smoke from passing through the entrance and exit of the elevator hall space of the emergency elevator (herein, it will have this type of fire door). Performance doors or rolling shutter doors are collectively referred to as fire doors) to enclose the space of the lift passage of the emergency elevator and the...
