Description

  The present invention relates to a wall-type building suitable for a middle- and low-rise apartment house.

  Medium- and low-rise apartments may employ a wall-type structure that supports buildings with flat structures such as walls and floorboards. In the wall-type structure, the amount of the load-bearing wall that supports the building is determined in accordance with the size of the floor area in each of the crossing direction and the spanning direction of the building. In an apartment house, a wall that serves as a partition with a neighboring house usually extends in the spanning direction. By using this wall as a bearing wall, the amount of the bearing wall in the spanning direction is easily secured. On the other hand, openings such as daylighting windows and entrance / exit openings are formed on the walls in the row direction, so that the amount of load-bearing walls in the row direction cannot be sufficiently secured only by the walls forming the indoor space. For this reason, a part of the partition of the floor space in the indoor space is configured by a load bearing wall, thereby securing the amount of the load bearing wall in the beam running direction.

  However, in the conventional design in which the partition of the floor space in the indoor space is made the bearing wall and the amount of the bearing wall in the direction of the beam is supplemented, for example, it is not possible to form a large living space with a small floor space, and there is a degree of freedom in planning the living space. small. In addition, if the partition of the floor plan in the indoor space is configured with a load bearing wall, the load bearing wall cannot be removed due to the structure, so that the floor plan cannot be freely changed during the renovation.

  The problem to be solved by the present invention is to provide a wall-type structure building that can form a wide living space with a small floor plan and has a high degree of freedom in planning at the time of design and renovation.

  In order to solve the above-described problems, a wall-type structure building according to the present invention is a wall-type structure building that supports a building by a planar structure including a load-bearing wall, and a wall that forms an indoor space is configured by a load-bearing wall that supports the building. In addition, the gist of the present invention is that a load-bearing wall that supports the building is further installed in an external space outside the indoor space in the building across a wall that forms the indoor space.

  In this case, it is desirable not to install a bearing wall in the indoor space. And it is preferable that the load-bearing wall arrange | positioned in external space comprises the outer wall of a corridor or a balcony. At this time, a load-bearing wall that supports the building may be further installed between the wall forming the indoor space and the outer wall of the hallway or balcony. For example, you may comprise the wall which covers the piping space or storage space arrange | positioned in external space with the load-bearing wall which supports a building.

  According to the wall-type structure building according to the present invention, the wall forming the indoor space is constituted by the load-bearing wall that supports the building, and the external space outside the indoor space in the building is separated by the wall forming the indoor space. By installing a load bearing wall that supports the building, it is possible to form a large living space with less floor space and to increase the degree of freedom in planning during design and renovation.

It is a planar view conceptual diagram of the wall-type structure building which concerns on this invention. It is the sectional view on the AA line of the wall-type structure building in FIG. It is a planar view conceptual diagram of the conventional wall-type structure building. It is the BB sectional view taken on the line of the wall-type structure building in FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual plan view of a wall-type structure building according to the present invention. FIG. 2 is a cross-sectional view taken along line AA of the wall-type structure building in FIG.

  As shown in FIGS. 1 and 2, the living space S of the wall-type structure building 10 includes a pair of walls 12 a and 12 b in the crosswise direction, a pair of walls 14 a and 14 b (or 14 a and 14 c) in the spanning direction, and upper and lower floorboards. It consists of a space surrounded by (ceiling) 16. All of the walls 12a, 12b in the crossing direction and the walls 14a, 14b, 14c in the spanning direction are made of load bearing walls that support the building. The bearing wall is made of reinforced concrete.

  In the living space S1 on the left side in FIG. 1, one wall 14a in the spanning direction is a partition between the neighboring house and the other wall 14b is a partition between the outside of the building. Moreover, in the living space S2 on the right side in FIG. 1, both walls 14a and 14c in the span direction are partitions between the neighboring houses. Although the wall 14b serving as a partition between the outside of the building has a window W, it extends in the entire span direction. Moreover, the walls 14a and 14c, which are partitions between the neighbors, have no windows and extend in the entire span direction. For this reason, the amount of the load-bearing walls in the span direction is sufficiently secured by using these walls as the load-bearing walls.

  On the other hand, openings X such as a daylighting window and an entrance / exit opening are formed in the walls 12a and 12b in the column direction. For this reason, it is difficult to secure the amount of the load-bearing wall only with the walls 12a and 12b that form the living space S in the girder direction. As shown in FIGS. 3 and 4, in the conventional wall-type structure building 30, a part or all of the floor space partition 32 in the indoor space S is configured with a load-bearing wall, thereby securing the amount of the load-bearing wall in the beam direction. Yes. However, in the conventional design in which the amount of the load-bearing wall in the crossing direction is supplemented by the floor space partition 32 in the indoor space S, for example, it is not possible to form a wide living space with a small floor space, and the degree of freedom in planning the living space is small. In addition, when the floor space partition 32 in the indoor space is configured by a load bearing wall, the load bearing wall cannot be removed because of the structure, and thus the floor plan cannot be freely changed during the renovation.

  Therefore, in the present invention, as described above, the walls forming the indoor space S (for example, 12a, 12b, 14a, 14b, 14c, etc.) are constructed of bearing walls that support the building, and the walls that form the indoor space S are A bearing wall that supports the building is further installed in an external space outside the indoor space S. The external space is not a space outside the building but a space outside the indoor space in the building, and includes a (shared) corridor 18 and a balcony 20 of the housing complex as shown in FIGS. In the (shared) corridor 18 and the balcony 20 of the apartment house, long outer walls 18a and 20a are formed in both the beam direction and the span direction, particularly in the direction of the beam, so that the outer walls 18a and 20a can be used as bearing walls. The amount of the load-bearing wall in the column direction can be increased as compared with the conventional case.

  In addition, a load bearing wall is further installed between the wall 12a in the crossing direction that forms the indoor space S and the outer wall 18a of the (shared) corridor 18, or between the wall 12b in the crossing direction and the outer wall 20a of the balcony 20. May be. (Shared) The corridor 18 may be provided with piping spaces such as electric piping and gas piping. In addition, in the (shared) corridor 18 and the balcony 20, a storage space serving as a storage may be installed. For example, FIG. 1 shows an example in which a meter box M and a trunk room T are installed in the (shared) corridor 18. The piping space and the accommodation space are usually partitioned by a simple partition and are not constituted by a load bearing wall. When installing such a space, the amount of the load-bearing wall in the direction of travel can be increased by using a wall that partitions the space and using this as the load-bearing wall.

  By installing the load bearing walls in the external space in the building in this way, the amount of the load bearing walls in the beam running direction can be increased as compared with the conventional case, and the amount of the load bearing walls in the beam running direction can be sufficiently secured. Thereby, it can be set as the structure which does not install a bearing wall in the interior space S. FIG. In the present invention, it is preferable to install a bearing wall in the external space and increase the amount of the bearing wall in the beam direction so that the bearing wall is not installed in the indoor space S. A load bearing wall may be installed at an arbitrary location in the indoor space S as long as a large living space can be formed in which a degree of freedom is secured.

  As described above, according to the wall-type structure building 10 according to the present invention, the wall forming the indoor space S is configured by the load-bearing wall that supports the building, and the indoor space S in the building is separated by the wall forming the indoor space S. By installing a load-bearing wall that supports the building in the external space outside, it is possible to form a large living space with less floor space, and to increase the degree of freedom in planning during design and renovation.
