JP4256239B2 - Extension method of apartment complex and extension structure of apartment complex - Google Patents

Description

  The present invention relates to an extension method in an apartment complex in which a plurality of apartment houses are constructed in parallel, and an extension structure of an apartment complex obtained by extending the apartment complex.

In Japan, many housing complexes were built from the 1950s to the 1940s in which multiple apartments were built in parallel.
Many of these apartments are so-called staircase type apartments with an outdoor staircase connected to the entrance to each unit between adjacent units. Many of these apartments are aging and are urgently needed. Rebuilding is desired. However, rebuilding all existing residences is not easy because of the problems such as the generation of a huge amount of building waste and the moving of residents accompanying the rebuilding.
In addition, since there are many elderly people living in the existing staircase-type apartment houses, it is difficult for the elderly living on the upper floors to go up and down the stairs, which also requires rebuilding. This is one major factor.

Therefore, in view of such circumstances, a method has been proposed in which an existing staircase type apartment house is remodeled into a one-way corridor type apartment house and an elevator is newly installed (for example, see Patent Document 1).

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an extension method for an apartment complex and an extension structure for an apartment complex according to the present invention will be described with reference to the drawings.
INDUSTRIAL APPLICABILITY The present invention can be suitably applied to an apartment complex in which a plurality of apartment houses are constructed in parallel, and in particular, an apartment complex composed of a staircase type apartment house. An example will be described in which an existing staircase type apartment house is expanded to a 10-story one-way corridor apartment house.
However, the present invention is not limited to the following examples. In the case where the existing apartment is 4 stories or less, 6 stories or more, or a one-way corridor apartment, the newly added apartment is 9 stories or less. It can be applied to the case of 11 stories or more.

FIGS. 1 to 13 are diagrams showing an extension method according to the present invention. FIGS. 1 to 6 are plan views, and FIGS. 7 to 13 are elevation views. Show.
FIG. 1 is a plan view showing a state before construction of the extension method according to the present invention, and FIG. 7 is an elevation view showing a state before construction of the extension method according to the present invention. Although the figure shows a state where two existing apartment houses are arranged in parallel, the present invention is also applicable to a case where three or more existing apartment houses are arranged in parallel.
In the illustrated example, the existing apartment house (1) is a staircase type apartment house having a structure including an outdoor staircase (3) connected to the entrance to each residence unit (2) between adjacent residence units (2). In the extension method according to the present invention, when the existing apartment house (1) is a staircase type apartment house, the existing apartment house (1) is reconstructed into a one-way corridor type apartment house.

In the extension method according to the present invention, first, as shown in FIG. 2 and FIG. 8, existing apartment houses (1) located between a plurality (two in the illustrated example) of the existing apartment houses (1) and at both ends. A new foundation (5) is provided on the outside. This new foundation (5) shall be a foundation with seismic isolation function.
In the illustrated example, since there are two existing apartment buildings (1) in parallel, it is sufficient to provide at least three new foundations (5), but in the case of three buildings, at least four, in the case of four buildings, At least five are provided.

  These new foundations (5) are preferably provided so as to be located on the same straight line and parallel to each other as shown in FIG. And when each new foundation (5) is connected with a straight line like illustration, this straight line is made to cross the existing apartment house (1). The crossing angle at this time, that is, the crossing angle between the straight line and the straight line connecting the dwelling units of the existing apartment is not particularly limited, and may be a right angle or a non-right angle. An angle (angle on the acute angle side) is appropriate, and is about 75 ° in the illustrated example.

In the present invention, when a plurality of existing apartment houses (1) are arranged so that their longitudinal directions are parallel to each other in plan view, particularly as shown in FIG. 2, adjacent existing apartment houses (1). This is preferably applied when the positional deviation in the longitudinal direction is small. This is because the interval between the new foundations (5) can be shortened, so that the construction work of the extension is excellent and the structure of the extension part is stable in strength.
However, the present invention is also applicable when a plurality of existing apartment houses (1) are arranged differently from FIG. FIG. 14: is a schematic plan view which shows the example from which arrangement | positioning of several existing apartment houses (1) differs, and the extension constructed | assembled in the upper part of the position of the new foundation (5) in each case, and a new foundation (5) The part (illustrated by a straight line) is shown.
(A) is a case where a plurality of existing apartment houses (1) are arranged so that the longitudinal directions in the plan view are parallel to each other and the longitudinal positions thereof coincide with each other; When arranged on the line, (c) shows a case where the longitudinal direction is a right angle and the existing apartment house (1) is arranged in a T shape in plan view, and (d) shows a plurality of existing apartment houses (1). Is a case where the longitudinal directions in the plan view are arranged so as to be parallel to each other and the positions in the longitudinal direction are greatly shifted.

In addition to the new foundation (5), as shown in FIGS. 2 and 8, the foundation (6) (hereinafter referred to as the following) The extension foundation (referred to as “6”) is newly installed on the outdoor staircase (3) side of the existing foundation of the existing apartment house (1).
This extension foundation (6) may be installed either before or after the new foundation (5) is installed, or in parallel with the installation of the new foundation (5).
Next, a column (7) made of a steel column or the like is erected on the extension foundation (6), and a beam (4) is provided between these columns (7) (see FIG. 2). ) On each floor of the existing apartment house (1), a new corridor (8) facing all adjacent dwelling units (2) is provided (see FIGS. 3 and 9). In addition, an evacuation stairs (9) is newly installed at the outer position facing the hallway (8) as shown in FIG.

  Then, the existing outdoor staircase (3) is removed, and the newly provided hallway (8) and the existing apartment house (1) are connected by an expansion joint (see FIG. 10). Of the two existing apartment houses shown in FIG. 10, the right side shows the construction completion state of this process, the left side shows the state during construction of this process, and the left side (A) part shows the outdoor staircase ( 3) is removed and a floor is added to the removed part. In part (B), the new hallway (8) and the existing apartment house (1) are connected by an expansion joint.

Through the above construction process, the existing apartment building of the staircase type (1) is expanded to a one-way corridor type apartment house, which makes it easier for residents to evacuate and ensures privacy among residents. It becomes easy.
In addition, when the existing apartment house (1) is a one-way corridor type apartment house from the beginning, this reconstruction process becomes unnecessary, and the corridor (8) can be used instead of a new one.

In addition, on the upper part of the new foundation (5), a core-type support pillar (10) made of a steel frame or the like for supporting the extension floor constructed above the existing apartment house (1) is erected (FIG. 3). And see FIGS. The standing of the support pillar (10) may be performed in parallel with the standing of the pillar (7), or may be performed before or after that.
Next, a beam (11) is installed between the support columns (10) above the existing apartment house (1) so as to straddle a plurality (two in the illustrated example) of existing apartment houses (1) in parallel ( (See FIG. 4 and FIG. 11).
And by providing a roof (12), a floor (13), and a hallway (14) on the upper part of these beams (11), as shown in FIGS. A new residence floor (16) with 15) is formed. In the illustrated example, a state in which new residence floors (16) for five floors are formed is shown.

  As the beam (11), a steel beam may be used. However, since the beam has a large span, a structure in which a shaft made of carbon fiber or basalt fiber solidified with synthetic resin is combined with a three-dimensional solid truss structure. It is preferable to use a material. A structural material having such a three-dimensional space truss structure is light in weight because the shaft itself has both high tensile strength due to fibers and high compressive strength due to resin, and the load is dispersed by the three-dimensional space structure. This is because extremely high strength can be exhibited.

In addition, an elevator (17) that reaches the rooftop of the expanded floor from the ground is installed between the adjacent existing apartment houses (1). This elevator (17) can be boarded / exited from either the newly-established corridor (8) in the existing apartment house (1) or the corridor (14) provided on the newly expanded residence floor (16). Thus, it installs in the position (For example, position where both corridors (8) and (14) cross | intersect) which faces both corridors (8) and (14).
Furthermore, an evacuation stairs (18) capable of descending to the ground is provided at a position facing the corridor (14) provided on the newly-extended new residence floor (16).
The elevator (17) and the evacuation stairs (18) are preferably installed at the same time as the beam (11) or before or after the beam (11). More preferably, it is performed in any of the steps before and after the roof (12), the floor (13), and the hallway (14) are provided on the upper part of the above.

And finally, as shown in FIG.6 and FIG.12, the connection channel | path (19) which connects adjacent existing apartment houses (1) is provided. As shown in the figure, the communication passage (19) preferably connects the rooftops, but it is also possible to connect other floors. Moreover, the existing housing parts of another apartment house extended by the said method can also be connected.
In this way, by connecting existing apartment houses in parallel with each other through a communication passage, the extended apartment house is regarded as one building as a whole, and clears the shade regulations of the Building Standards Act. It becomes easy.
In particular, in an apartment complex where multiple apartments are built side by side at relatively narrow intervals, if you intend to add each apartment building upward individually, you will need to consider the shading regulations for each individual building. However, by expanding each apartment building so that it can be regarded as a single building, it is not necessary to examine the shading regulations for each building in the expanded building. It will be necessary to consider only the shade control, and it will be easy to perform an upward extension.

Moreover, the resident who lives in an existing apartment house (1) goes to the rooftop of another existing apartment house through a connection passage (19) by going up to the rooftop using the evacuation stairs (9) or the elevator (17). Therefore, safe evacuation is possible in the event of a fire or the like.
At this time, as shown in FIG. 13, if the evacuation stairs (20) and the elevator (21) are installed at appropriate locations along the communication passage (19), evacuation to the ground can be performed more quickly. This is preferable. FIG. 12 and FIG. 13 are both diagrams showing the completion of the extension, but the layout of the escape stairs (19) and the like is slightly different.

  As shown in FIG. 6, it is preferable that the rooftop of the existing apartment house (1) and the rooftop of the newly-extended new residence floor be green. As a result, it is possible to alleviate the heat island phenomenon in summer and to save energy by suppressing the temperature rise in the apartment house.

  According to the extension method described above, the dwelling unit (2) of the existing apartment house (1) can be renewed by moving the residents who lived in the existing apartment house (1) to the newly added upper floor. It becomes possible. When the renewal is over, the residents may move to the lower floor where they originally lived, or in some cases they can live on the upper floor as they are. The person should be resident. Therefore, existing residents do not need to move out to the outside, and daily life is prevented from being hindered by construction noise and the like.

  According to the apartment house extended in this way, the resident who lives in the lower floor, that is, the existing apartment house (1), and the resident who lives in the upper floor, that is, the extended residence floor, face each dwelling unit. It is possible to go back and forth from the hallway (8) (14) by using the elevator (17), and residents who originally lived in different existing apartment houses (1) go back and forth using the communication passage (19). In addition, since residents living on the extended residence floor can go back and forth through the corridor (14), exchange between residents is facilitated, and convenience in daily life is greatly improved.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used when a plurality of apartment houses, in particular, an apartment complex in which a staircase type apartment house is constructed in parallel, is added.
