JP6784474B2 - Elevator installation method in existing apartments and their existing apartments - Google Patents

Description

The present invention relates to an elevator installation method in an existing apartment house without an elevator and an existing apartment house in which the elevator is installed.

Conventionally, there are many cases where there is no elevator in low- and middle-rise apartments such as old condominiums, apartments, and housing complexes built in the 1950s and 1940s. For example, as shown in FIG. 4, adjacent dwelling units 21 and 22 and dwelling units 23 and 24 are combined into a set, and stairs 25a and 25b are provided between them, and both dwelling units 21 and 22 are provided in the landing 26a on each floor. There is known a low- and middle-rise staircase type apartment house provided with entrances 27a and 27b of dwelling units 23 and 24.

Elderly people often live in such old apartments, so in order to make them friendly to the elderly, we will install elevators to make them barrier-free, and the declining birthrate and aging society and diversifying needs In response to this, renewal of dwelling units to serviced housing for the elderly is being carried out.

The ones described in Patent Documents 1 to 3 are known as examples of regeneration by installing an elevator in an existing apartment house without an elevator.

However, the conventional method of installing an elevator in an existing apartment building is, for example, a landing type (see Fig. 5), but this is completely barrier-free because you have to go up and down the stairs after getting off the elevator. It does not become a barrier and is not suitable for the elderly. In addition, there is a staircase renovation type (see FIG. 6), but this not only requires the installation of an elevator for each staircase, but also requires the renovation of the staircase, which increases the repair cost. In addition, there is an external (single) corridor extension type (see Fig. 7), which is newly established for the extension of single corridors / staircases 25a and 25b such as corridors 28 and crossing corridors 30 and the renovation of staircases. The part becomes large, and the repair cost for making it completely barrier-free increases significantly.

In each of the above elevator installation methods, considering that many elderly people are occupying old existing apartments, it is necessary to minimize the impact on daily life and reduce the burden of construction costs. The elevator installation method for an existing apartment house and the existing apartment house according to the present invention have been proposed in order to solve such a problem.

The gist of the method of installing an elevator in an existing apartment house according to the present invention and the method of installing an elevator in the existing apartment house in order to solve the above problems and achieve the object is the number of rooms in the apartment house. A common corridor is formed inside while leaving the outer wall and the wall part of the stairs, and the opening is expanded so that the common corridor and the elevator hall can pass through, and they are connected by an expansion joint, and the window. Only the elevator hall and the elevator room that formed the part were added to the outside of the apartment building.

The common corridor is formed by remodeling a part of the living space, and the end of the common corridor is formed by communicating with the stairs, and a fire door is installed on the wall of the stairs at the communicating position. It is that you are.

The opening as a window in the existing apartment house is removed, and the window is secured in the landing for the elevator connected to the opening.

The gist of the existing apartment house according to the present invention is that an elevator room is added to the existing apartment house by the elevator installation method for the existing apartment house according to the present invention.

According to the method of installing an elevator in an existing condominium according to the present invention and the existing condominium, the construction cost is suppressed, the construction period is shortened, and the elderly is friendly by reducing the removal of the existing skeleton and the extension of the new skeleton as much as possible. Barrier-free is achieved. As a result, the old low- and middle-rise existing apartment buildings will be renovated into high-value-added services for the elderly.

In addition, since a part of the living space will be renovated in the common corridor, it will be a preferable renovation work in the building corridor from the viewpoint of resource saving and cost saving. Since the common corridor protrudes from the outside of the existing apartment building and is not expanded, it is a suitable elevator installation method for a small housing complex on an urban site.

Furthermore, since there is a staircase at the end of the common corridor and this staircase is not repaired, some of the dwelling units will be repaired as they are. Therefore, it has little effect on daily life for residents such as the elderly.

As for the removal work of the existing apartment house, only the opening as a window, that is, the waist wall (bearing wall) and the eaves at the joint part with the elevator building to be expanded will be removed, which will be the minimum necessary repair work. The removed opening will be secured as a window even in the joint and landing after the repair, and the lighting and ventilation of the extension building will be secured.

In addition, since the renovation work of the existing apartment house and the extension work of the elevator landing and the elevator room are carried out at the same time and in parallel, the renovation work period is shortened, which has many excellent effects. Is.

As shown in FIGS. 1-A and 1-B, the elevator installation method for an existing apartment house and the existing apartment house according to the present invention form a common corridor inside the existing apartment house and form a corridor inside the building. It is an installation type repair work.

As shown in FIGS. 1-A to 2, the method for installing an elevator in an existing apartment house according to the present invention is an existing apartment house 20 (FIG. 4) without an elevator, such as a housing complex built in the low- and middle-rise buildings in the 1955's. (See) will be made barrier-free in preparation for an aging society.

Therefore, a common corridor is formed inside the existing apartment house 20. For this purpose, a part of the adjacent dwelling units (including bedroom, living room, hall, washroom, bathroom, etc., hereinafter the same) 22 and 23 is made into a common corridor 2. That is, as the first embodiment, as shown in FIG. 1-A, the new wall 6 is constructed while leaving the wall 5 between the adjacent dwelling units 22 and 23 as it is. As a result, a new entrance 8 is formed, and doors 27a and 27b for the entrance 8 are provided at the opening.

The end of the common corridor 2 is connected to the landing 26a on the floor in the stairs 25a and 25b. Further, at the boundary between the common corridor 2 and the landing 26a, the entrance doors 27a and 27b of the dwelling units 22 and 23 are removed, and instead, a fire door (door) 7 is provided, for example, in a closed manner at any time. Has been done.

Since the common corridor 2 was provided by renovating a part of the dwelling units 22 and 23, the usable area was reduced compared to before the renovation, but for the elderly living alone or two people, there is sufficient living space. It is secured and does not pose a major obstacle.

In the communication portion between the common corridor 2 and the elevator hall 3, the waist wall and the eaves are removed from the window portion 29 which is the opening shown in FIG. As shown in FIG. 1, this communication portion has an opening that allows people to pass through and is connected by an expansion joint. Reinforcing bars will be installed and existing reinforcing bars will be repaired at the opening extension. Further, a window portion 9 which is an opening is provided to ensure daylighting and ventilation of the extension portion.

Along with the renovation of the existing apartment house 20, only the elevator hall 3 and the elevator room 4, which are the landings for elevators communicating with the common corridor 2, will be expanded outside the existing apartment house 20. As shown in FIG. 2, the renovation work of the existing building of the existing apartment house 20 and the extension work of the elevator room 4 are carried out simultaneously. Residents of dwelling units 21 and 24 will be constructed with their residences even during the renovation work. Therefore, the labor and cost of moving can be saved.

As a result, since there are few large-scale skeleton removal works or new concrete works, it is possible to start interior finishing work early, and the construction period of the entire repair work can be shortened.

In the communication portion between the common corridor 2 and the elevator hall 3, the waist wall and the eaves are removed from the window portion 29 which is the opening shown in FIG. As shown in FIG. 1, this communication portion has an opening expanded so that people can pass through it, and is connected by an expansion joint (continuously closed state to the outer wall) . Reinforcing bars will be installed and existing reinforcing bars will be repaired at the opening extension. Further, a window portion 9 which is an opening is provided to ensure daylighting and ventilation of the extension portion.

As shown in FIGS. 1 and 4, the conventional existing apartment house 20 has staircase portions 25a and 25b on the left and right sides. Therefore, there are stairs communicating with each other on both sides of the common corridor 2, and the elevator room 4 to be expanded is arranged between the stairs 25a and 25b on both sides. As shown in the figure, as an example, the elevator room 4 is arranged at an intermediate position between the stairs on both sides.

After the renovation of the existing apartment building, the interior and exterior repairs, and the extension work of the elevator room 4, each interior is finished, the exterior walls are painted, and then the scaffolding is dismantled and the outdoor maintenance is performed to renovate the residential building. Is completed.

As a method of installing an elevator in an existing apartment house according to the present invention, as shown in FIG. 1-B, a method of further reducing the area of new skeleton extension is proposed. This is to remove a part of the wall 5 which is the partition wall of the adjacent dwelling units 22 and 23 when constructing the common corridor 2 in the building installation type.

In the second embodiment, the common corridor 2 is entirely installed in the building and is not projected outside the existing apartment house 20. Therefore, the new skeleton extension area (m ² ) is only the elevator hall 3 and the elevator room 4, which is the smallest area as shown in FIG. 3 as compared with the conventional elevator installation method. Therefore, in an urban area where there are many small-area apartments, there is no problem in securing site space for renovation and regulating the building coverage ratio.

Others are the same as in the first embodiment, and the dwelling units 21 and 24 are constructed with a residence, the repair cost is low, and the cost burden associated with the repair for the elderly and the like is small.

According to the method of installing an elevator in an existing apartment house according to the present invention, the existing apartment house 20 having no elevator in the low and middle layers is expanded into an existing apartment house 1 which is friendly to the elderly by expanding the elevator room.

According to the method of installing an elevator in an existing apartment house and the existing apartment house according to the present invention, there is little dismantling / removal work of the existing skeleton even in an old housing complex where elderly people live, the cost is suppressed, and an elevator to be added is added. Since the required area of the room and the hall is small, it can be widely applied.
