DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an apartment house,
In particular, the present invention relates to a floor plan of an apartment house suitable for a one-hall corridor apartment house having a frontage of 5 m or less and a housing area of 50 m ² or less.

[0002]

2. Description of the Related Art In Japan, 1960 apartments are used.
Construction began in earnest around the year, and many of the apartments constructed around this time have become difficult to use now due to the improvement in living standards following changes in socioeconomic conditions.

[0003] In particular, it is known that many public rental housings are deteriorated, and those that are more than 40 years old are rapidly increasing in the future. Many of these houses are narrow, about 30 m ² , and most of the residents are elderly (1-2).

[0004] In such a situation, the scale of newly built dwelling units has become a major problem in rebuilding. In other words, as a public business entity, we want to supply 65 to 70 m ² (family type) based on the principle of “type supply (providing various types of plans and housing of various sizes)” and future demand forecasts. Given the rent burden of previous residents, lies in supply forced situation the narrow dwelling units (45m ² before and after).

[0005] Therefore, an apartment house of about 45 m ² per house is constructed for the time being, and if necessary, it will be replaced by 70 m ² per house as needed.
It is reasonable to be able to expand to the extent.

However, single units 45 m ² before and after the apartment, for example, frontage below 5 m, residential area of 50 m ² or less (depth over 10m) provided outside the corridor along the elongated dwelling unit group of a balcony on the opposite side In a typical single-hall corridor apartment house, such renovation is very difficult for the following reasons.

For example, each house is about 45 m ² (the frontage is about 4.
Taking a 2K plan as an example in a one-hall corridor type apartment house (5 m, depth about 10 m), the limitation due to the narrowness of the frontage is large, and the layout has to be almost as shown in FIG. That is, as shown in FIG. 6, living rooms (room 1 and living room 2) are arranged one by one on the external corridor side and the balcony side, and water places such as kitchen, toilet, bathroom and washroom are arranged in the center. I have to do it.

[0008] Of the water fountains, bathrooms, washrooms, and toilets are gathered in one place and arranged to one side of the dwelling unit.
This is because it is necessary to make the entrance 4 as close as possible to one door wall 1A in order to make the room (the living room 2) on the outside corridor wide.

In order to effectively utilize the depth of the elongated dwelling unit, the toilet and the bathroom / bathroom are arranged vertically (in the depth direction), and the kitchen is opposed to the toilet / bathroom / bathroom. At the position, it is disposed vertically (long in the depth direction) along the other door wall 1B.

[0010] The door border wall 1A, which is constructed on the structure in the direction between the beams,
1B are all structural walls made of RC and are structurally advantageous, so that they are arranged linearly.

From the above 2K plan, in order to expand each house to about 70 m ² , one door wall 1A is を of the frontage H.
In the case of moving about (approximately 2.25 m) and remodeling to, for example, a 3LDK, the following problems will occur. Since the doorway wall 1A is made of RC, it takes a lot of time and effort to remove it. Moreover, since the structural wall is to be removed, large-scale reinforcement is required so as not to affect the strength of the structure of the whole building. is necessary. Since the kitchen, which is a water hole, is placed in contact with the doorway wall 1A, the doorway wall 1A is removed as it is, and the frontage wall 1A is removed.
/ 2 (approximately 2.25m)
Two slender and inconvenient rooms 8a and 8b and the accommodating portion 9 associated therewith are formed, and the movement of the kitchen (change of water place) is inevitably required.

From the above, remodeling is very difficult, and even if remodeling is carried out, a large amount of cost is required for skeleton work (removal, movement, and reinforcement of the border wall) and renovation work around the water area. Because it is necessary, it is very uneconomical and noise during construction is also a major problem.

As a countermeasure, the use of a skeleton house, which has recently become a hot topic, can be considered. However, the skeleton house, which is generally referred to, has no structural wall and has a pipe shaft on which a common vertical pipe is disposed outside. In order to cope with long horizontal pulling pipes with drainage slopes, large double floors and double ceilings are used to pursue freedom of plans and response to changes. This has resulted in significant cost increases, and under the current tight financial situation of public enterprises, this measure is completely unacceptable.

[0014]

SUMMARY OF THE INVENTION In view of the above situation, the present invention provides a simple and inexpensive multi-unit housing that can be remodeled from three to two, in other words, it can easily and inexpensively reduce the area of a house to one. The present invention provides a multi-family housing with a floor plan that can be expanded by a factor of five.

[0015]

The technical measures taken by the present invention to solve the above-mentioned problems are as follows. That is, in the apartment house according to the present invention, the door wall of the three adjacent dwelling units is a dry non-structural wall and is bent in a crank shape, and the lavatory facing the inner corridor of the dwelling unit is arranged so as to protrude to the next door side, A living room is arranged at each end in the depth direction, and a bathroom / washroom and a kitchen are arranged side by side in the depth direction at the center in the depth direction, with the toilet separated from the corridor. Features.

According to the above configuration, since the door wall is a dry non-structural wall, it is troublesome to remove or relocate the door wall when expanding the housing area by changing the position of the door wall. In addition, there is no need to reinforce the skeleton during removal, and the occurrence of noise problems can be suppressed.

In particular, since the doorway wall, which is a dry type non-structured wall, is bent in a crank shape and the toilet facing the corridor in the dwelling unit is arranged so as to protrude to the adjacent door side, an area other than the toilet is limited by the protruding area. The next door will enter the location. Therefore, in order to renovate three houses to two houses and expand the housing area by 1.5 times, when the door boundary wall is moved about 1/2 of the frontage, the extended part can be moved without moving the toilet. Since the width of the two rooms formed in the area can be secured, the toilet does not need to be moved, and the unused water areas (toilet, bathroom / washroom, It is only necessary to remove the kitchen, etc., and the renovated 2 dwelling units do not need to change the location of the toilet, bathroom / washroom, and kitchen (the location of the water place). We can save.

Further, since it is not necessary to change the position of the water place, the pipe shaft can be provided in the dwelling unit, and the horizontal drawing pipe is shorter than the case where the pipe shaft is provided outside. The floor height is kept low, the construction cost for new construction is not high, the relocation of air supply / exhaust ducts that require beam penetration is not required, and spare sleeves are not required. is there.

Further, depending on the planning, the replacement work of the outer wall and the sash of the expanded portion can be achieved by simply replacing the entrance door of the adjacent door before the renovation with the window sash, and the cost can be further reduced.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the present invention is shown in FIG.
It will be described conceptually based on. Figure 1 shows the exterior corridor-type apartment complex before renovation (2K plan) and after renovation (3LD)
2 shows a schematic plan view of a dwelling unit of the (K plan). In the figure, only the left one of the three adjacent dwellings is shown. The dwelling unit before renovation is a slender dwelling unit having a housing area of about 45 m ² , for example, a frontage of 5 m or less and a housing area of 50 m ² or less. In the figure, 1A and 1B are door border walls,
The door wall 1A on one side is a dry non-structural wall. As the dry non-structural wall, for example, a gypsum board, an extruded cement board, a slate board, an ALC board, a composite material thereof and the like are used. The other door wall 1B is a linear structure wall made of RC.

As shown in FIG. 1 (A), the door wall 1A, which is a dry non-structural wall, is bent in a crank shape before renovation, and the toilet 3 facing the corridor 2 in the dwelling unit is provided. It is located on the side of the next door. Reference numeral 4 denotes an entrance facing the external corridor. Living rooms 5a and 5b are provided at both ends in the depth direction, respectively.
(Room 1 and Room 2) are arranged one by one, that is, one room (Room 2) is arranged on the outside corridor side, and one room (Room 1) is arranged on the balcony side. A bathroom / lavatory 6 and a kitchen 7 are arranged side by side in the depth direction at the center in the depth direction with the toilet 3 separated from the corridor 2.

Then, three houses are remodeled into two houses to expand the housing area about 1.5 times, and the 2K plan shown in FIG. 1A is replaced with the one shown in FIGS. 1B and 1C. When remodeling to the 3LDK plan, as shown in Fig. 1 (B) and (C), the door boundary wall 1A is removed and this is made into a linear shape.
By moving about half the width of the frontage, the area of the house is expanded, and two rooms 8a and 8b (room 1 and room 3) and a storage 9 attached to the rooms 8a and 8b are formed in the expanded portion.

In this case, as shown in FIG. 1 (A), the border wall 1A is bent in a crank shape, and the toilet 3 facing the corridor 2 is disposed so as to protrude to the adjacent door side. The next door will enter the location other than the toilet 3 minutes.
Therefore, as shown in FIG. 1B and FIG.
When A is moved about 間 of the frontage, the two rooms 8a and 8b formed in the expanded part can be moved without moving the toilet 3
Since the width of the toilet can be secured, the toilet 3 does not need to be moved, and the position of the water place does not need to be changed at all, and the repair work cost around the water place can be reduced. In addition, since the doorway wall 1A is a dry non-structural wall, the removal and relocation of the doorway wall 1A does not require any trouble, and the removal of the skeleton is not required.
Noise problems can also be suppressed.

FIG. 1B is a plan in which the toilet 3 in the dwelling unit before the renovation is used as it is, and FIG. 1C is a plan of the dwelling unit in the adjacent unit before the renovation and the dwelling unit in the dwelling unit after the renovation. 3
It is a plan to use as. In either plan, the toilets that are no longer needed will be removed, but the location of the toilet 3 to be used (the location of the water place) will remain the same, and the locations of the bathroom / toilet 6 and kitchen 7 to be used will be the same. Since it does not change, it is only necessary to remove unnecessary water stations (toilets, bathrooms / washrooms, kitchens), and the cost of repair work around the water stations can be reduced.

Next, an embodiment of the present invention will be specifically described with reference to FIGS. FIG. 2 shows three dwelling units in an external corridor-type apartment house before renovation. Renovation previous 3 dwelling units are all in frontage 5m or less (3 dwelling units of frontage is set to be equal.), Residential area is 50 m ² or less elongated dwelling unit. Of the three dwelling units, the two dwelling units on both sides have a contrasting layout of the 2K plan, and the one dwelling unit in the center has a 1LDK plan layout. FIG. 3 shows a state where three dwelling units in the apartment house of FIG. 2 have been renovated into two dwelling units having a housing area of 1.5 times.

The apartment house shown in FIG. 2 is about 45 m ² to about 50 m.
It is framed with 3 units of ² dwelling units as 1 structural unit,
Doors 1A, 1 on the construction surface in the direction between beams (in the depth direction of dwelling units)
B has been constructed. Of the border walls 1A and 1B, the border wall 1B located every three spans is a linear structure wall made of RC, and the two border walls 1A located therebetween are dry non-structural walls. It has been. Examples of dry non-structural walls include gypsum board, extruded cement boards, slate boards,
ALC plates, composites thereof, and the like are used. 10 is a pillar,
The broken lines between the columns 10 indicate beams.

As shown in FIG. 2, the door wall 1A, which is a dry non-structural wall, is bent in a crank shape, and
Toilet 3 facing the door is overhanging to the next door. 4
Is an entrance facing the external corridor, and 11 is a balcony provided on the opposite side of the external corridor, which is partitioned by an evacuation partition 12. Living room 5 at each end in the depth direction
a and 5b are arranged one by one, and in the central part in the depth direction, the toilet 3 is separated from the corridor 2 by a bathroom / toilet (a bathroom 5a and a toilet 5b composed of a unit bath) and a kitchen 7. Are arranged side by side in the depth direction. 13 is a sink,
Kitchen unit consisting of stove, etc., 14 closet, 1
Reference numeral 5 denotes a closet, PS denotes a pipe shaft provided in each dwelling unit, and MB denotes a meter box provided for each dwelling unit facing the external corridor.

The two dwelling units on both sides shown in FIG. 2 have a 2K plan, so the kitchen and the living room are partitioned by a partition 16. However, since one dwelling unit in the center has a 1LDK plan, the kitchen 7 and the living / dining room are separated. (Room 5a) is one room. In addition, in the illustrated example, since the span in the direction between beams is large, the independent pillar 10a is constructed at a position overlapping with the door border wall 1A.
0a is omitted.

As shown in FIG. 3, the above-mentioned apartment house is obtained by removing the crank-shaped door wall 1A and providing the linear door wall 1A at a position which is moved by half of the frontage. The area is expanded, and two rooms 8a and 8b are formed in the expansion part, and storage units (closet 9a and walk-in closet 9b) 9 for those rooms 8a and 8b are formed. Can be remodeled into two dwelling units.
The newly renovated 2 dwelling units have a 3LDK plan layout, but the room 8a on the balcony 11 side of the expanded part and the LDK plan
(Room 5a) can be a single room.

In addition, the outer wall on the outer corridor side of the two renovated dwelling units is provided with a window sash 1 at the entrance door of the central dwelling unit before renovation.
The only change was to replace it with a 7, and the other entrances 4 and window sashes were left as they were, reducing the cost of renovation work related to the outer walls. The meter box MB provided for the central dwelling unit before the renovation becomes unnecessary after the renovation, but is left as it is because wiring and piping penetrating the upper and lower floors are provided. In addition, balcony 11
With regard to, only the unnecessary evacuation partition 12 is removed, and the evacuation partition 12 is installed at the position of the new doorway wall 1A.

In the left dwelling unit after the rebuilding shown in FIG. 3, the original toilet 3 is removed and the plan is to use the next toilet (center dwelling unit) 3 before the renovation. As is clear from the comparison in FIG. 3, even if the unnecessary toilet is removed, the position of the toilet 3 (the location of the water place) to be used after the remodeling has not changed, and the bathroom 5a and the washroom to be used. 5
Since b and the position of the kitchen (the position of the water fountain) do not change, it is only necessary to remove unnecessary water fountains, thereby reducing the cost of repair work around the water fountain.

In particular, since the door wall 1A is a dry non-structural wall, removing and relocating the door wall 1A is not troublesome.
There is no need to reinforce the skeleton during removal, and noise generation can be suppressed. In the example shown in the figure, the replacement of the outer wall and sash of the extension portion is only required by replacing the entrance door of the adjacent door (center dwelling unit) with the window sash 17 before the renovation, which further reduces the cost. It is possible.

FIG. 4 shows another embodiment. As shown in FIG. 5, when three dwelling units are remodeled into two dwelling units, the left dwelling unit has a plan in which the original toilet 3 is used as it is. There is. In this apartment house, of the doorway wall 1A bent in a crank shape, a portion located from the toilet 3 to the balcony 11 side is linear and greatly enters the central dwelling unit side, so that among the three dwelling units, Only the central unit,
Although the frontage is set slightly wider than the two dwelling units on both sides, the layout and number of rooms and the location of water holes are the same as those in the embodiment shown in FIG. In addition, in the central dwelling unit, the kitchen unit 13 is vertically arranged along the border wall 1A, but may be horizontally arranged along the bathroom 6a as in the dwelling units on both sides.
