Description

  The present invention relates to an elevator structure in a medium-high-rise building such as an office building, a hotel, or an apartment house.

  In general elevators in medium- and high-rise buildings such as office buildings, hotels, and apartment buildings, an elevator shaft is provided in the core portion of the building, and the elevator cage moves up and down in the enclosed space.

  On the other hand, for example, in Patent Document 1, as a view elevator apparatus that can expand the field of view of a person riding in a cage and improve the appearance of the building, a lift passage for raising and lowering the see-through cage is formed in a recess on the outer wall surface of the building. It has been described.

  Further, in Patent Document 2, two high-rise and low-rise elevator banks in which two elevator shafts face each other across a high-rise floor or a low-rise floor entrance / exit lobby are arranged in parallel along a shared hallway, The high-rise floor and low-rise floor entrance / exit lobbies are connected to the common corridor for each floor via the separated portions of the high-rise and low-rise elevator banks and adjacent to the low-rise elevator bank on the opposite side of the high-rise elevator bank. An elevator core structure for a high-rise building is described in which an atrium connecting from a lower floor to a higher floor is formed, and a space between two elevator shafts of an elevator bank for a high-rise building formed on the lower floor is connected to the atrium. ing.

  In Patent Document 2, with the above configuration, the space between the two elevator shafts of the high-rise elevator bank can be made part of the floor surface, so that the floor-to-floor efficiency can be improved accordingly. As a result, the office space can be increased, the space efficiency is relatively good, and the shape and landscape of the atrium from the lower floor are completely different from the shape and landscape of the atrium from the higher floor. It is going to increase.

  Patent Document 3 discloses that an elevator cage is lifted and lowered in a colonnade space for the purpose of obtaining a sense of freedom and effectively using the atrium space for a two-story or three-story private house. Is described.

Japanese Patent Application Laid-Open No. 07-025565 JP-A-11-269994 JP-A-11-343664

  In a general form of elevator in medium- and high-rise buildings, the area of the elevator shaft portion is included in the volume of each floor, so that the elevator shaft portion is as small as possible with respect to the flat section of the cage in order to increase the efficiency. In general, it is designed to have a cross section.

  However, if the gap between the elevator shaft and the cage is small, the space for maintenance work is limited, which is disadvantageous in terms of work efficiency and work safety.

  In addition, in the event of an elevator failure or an accident, it may be difficult to rescue the passenger.

  The invention described in Patent Document 1 is originally an invention from the aspect of design such as securing a landscape from an elevator and improving the appearance of a building, and is not considered for ease of maintenance, failure or accident.

  The invention described in Patent Document 2 is intended to ensure the superiority in the volume ratio, but the merit in the effective ratio is slight, and in the relationship between the plane section of the elevator shaft and the plane section of the cage, There is no particular difference from conventional ones, and there are similar problems to conventional elevators in terms of maintenance, breakdowns and accidents.

  The invention described in Patent Document 3 seeks comfort through the design of the interior space in low-rise private houses, and is considered for ease of maintenance related to elevators for medium- and high-rise buildings, as well as breakdowns and accidents. is not.

  The present invention is intended to solve the above-mentioned problems in elevators for medium- and high-rise buildings, is easy to perform maintenance work, and repairs malfunctions and rescues passengers in the event of a malfunction. It is an object to provide an elevator for a medium- and high-rise building that can secure a sufficient space.

The elevator for medium- and high-rise buildings according to claim 1 of the present application is 2 of the total area of the flat cross-sections of one or a plurality of elevator cages installed as a space for installing the elevator in the flat cross-section of the medium- and high-rise buildings A blow-off space without an elevator shaft having a flat cross section of not less than 10 times and not more than 10 times is formed, and an opening / closing door for getting on and off is formed on at least one surface of the cage of the elevator, and the surface on which the opening / closing door is formed At least one surface other than is directly facing the atrium space.

  Since at least one surface of the cage faces the blow-through space, at least for that surface, a sufficient space can be secured between the cage and the wall. By using the space, maintenance work and repair work are facilitated, and it is easy to ensure the safety of workers. In addition, when the passenger needs to be rescued due to an accident or the like, the rescue operation can be performed using the space.

  In addition, the presence of the atrium space means that there is a larger cavity in the building than the conventional elevator shaft, but by using the shape and size of the cavity, the degree of freedom of design is expanded, and it is not always negative. Must not. In addition, there is a merit in the daylighting surface using the atrium portion.

  In order to ensure sufficient effects and superiority over the prior art for the elevators for middle and high-rise buildings of the present invention, the area of the flat section of the atrium space should be at least twice the total area of the flat section of the cage. desirable.

  In addition, if the blow-through space is too large, the significance as a work space for maintenance will be reduced, and access to the inside of the elevator from other than the opening / closing doors may be inconvenient, about 10 times or less Is considered desirable.

A second aspect of the present invention is the elevator for a medium- and high-rise building according to the first aspect , wherein the atrium space has a function of a living space where people can go in and out.

  For example, if the design is made to allow people to enter and exit as a living space, such as a refresh corner, on the first floor of the atrium (or the basement or the second floor or higher), the upper part of the atrium is included in the floor area. There is no room to do so, and the entire office building can be designed efficiently.

According to a third aspect of the present invention, in the elevator for a medium to high-rise building according to the first or second aspect , a part of the atrium space is provided as an arrangement space for equipment piping and / or equipment wiring.

  In this case, in addition to the advantage that it is not necessary to design the space for equipment piping and equipment wiring separately, there is an advantage that a wide space can be secured and maintenance and renewal work are easy.

According to a fourth aspect of the present invention, in the elevator for a medium- and high-rise building according to the first, second, or third aspect , an entrance that allows entry and exit between the blow-out space and the outside of the blow-off space is provided at the bottom of the blow-off space. It is a feature.

For example, in the case where the atrium space is provided with the function of a living space as in the second aspect, of course, some kind of enclosure for avoiding contact with the entrance and the elevator is necessary. Further, in general elevators, because there is not enough space, maintenance workers often go in and out of the elevator. However, in the present invention, a space as a blow-through is secured. By providing a doorway between the two, it can be used by maintenance workers. In addition, this doorway can be used as a passage for rescue and evacuation.

  Note that the lowest floor of the elevator stop may be the bottom of the atrium space or may be above the bottom.

  An atrium space provided as a space for installing an elevator in a flat section of a medium- to high-rise building can be used for maintenance work or repair of a failure.

  In addition, a part of this atrium space can be used as a living space, or it can be used as a space for facility piping and facility wiring, thereby enabling efficient design.

  In the event of an accident, rescue and evacuation can be made using the atrium.

  In the conventional structure, the plane section of the elevator shaft is included in the volume at each floor, whereas in the present invention, since there is no elevator shaft, only the floor area of the cage 12 needs to be included in the volume, thereby increasing efficiency. Design is possible, leading to an increase in floor space.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention, where (a) is a plan sectional view of a first floor portion, and (b) is a plan sectional view of a reference floor portion. FIG. 2 is a vertical sectional view corresponding to FIG. 1. It is the figure which contrasted and showed the prior art example ((a) figure) and this invention ((b) figure).

  Hereinafter, embodiments of the present invention will be described in detail. Note that the present invention is not limited to the embodiments described below.

  1 and 2 show an embodiment of the present invention. FIG. 1 (a) is a plan sectional view of a first floor portion, FIG. 1 (b) is a plan sectional view of a reference floor portion, and FIG. It is a vertical sectional view.

  In the present embodiment, an atrium space 11 having a sufficiently large plane cross section as a space for installing an elevator in a plane cross section of a medium to high-rise building is larger than the total area of the plane cross sections of the four cages 12 to be installed. Is formed.

  Each cage 12 is formed with an opening / closing door 12a for getting on and off at the elevator hall 13 side, and the surface on the opposite side faces the above-described blow-off space 11.

  If a window is provided on the surface of the cage 12 or a see-through is provided, the feeling of closing in the cage 12 can be alleviated, and the light in the blow-through space 11 can be taken into the cage 12. If this is not necessary, the cost of the cage can be reduced by using four surfaces of the cage 12 as walls.

  Further, in the present embodiment, as shown in FIG. 1A, a refresh corner 11a as a living space is provided on the first floor portion of the atrium space 11, and a person can enter and exit from the side entrance 11c. ing.

  In the refresh corner 11a, for example, a chair or table for a break, a vending machine, or the like can be installed, or a smoking space can be provided.

  Furthermore, in this embodiment, rationalization of the design is achieved by using a portion close to the wall of the atrium space 11 as a facility piping or wiring space 11b.

  The entrance 11c can be used not only as an entrance to the refresh corner 11a but also as a maintenance work or an emergency exit.

  FIG. 3 shows the structure and function when an elevator shaft 1 is provided in a conventional general elevator (FIG. 3 (a)) and when a blow-off space 11 is provided at the elevator position of the present invention (FIG. 3 (b)). It is shown in contrast.

  In the case of Fig. 3 (a), which is a conventional structure, there is only a small space between the wall of the elevator shaft 1 and the cage 2, so that the maintenance work is performed only in the cage 2 or above and below the cage 2. I can't.

  In addition, the volume calculation of the elevator part in an office building, an apartment house, etc. is calculated on the assumption that each floor has a floor area corresponding to the plane section of the elevator shaft 1.

  On the other hand, in the case of FIG. 3 (b) of the present invention, since the atrium space 11 is formed, a sufficient space is secured, for maintenance work and repair, rescue of an occupant in an emergency, and evacuation. It can also be used as a space.

  Further, since there is no elevator shaft, only the floor area of the cage 12 needs to be included in the volume, thereby enabling efficient design. That is, the floor area can be increased in the comparison between the rental room 4 in FIG. 3A and the rental room 14 in FIG.

  The present invention can be applied to elevator facilities in medium- and high-rise buildings such as office buildings, hotels, and apartment houses.
