Description

  The present invention relates to a narrow building.

  In recent years, especially in urban areas where housing is concentrated, there are many buildings known as so-called narrow houses where houses are built on relatively narrow land. In such a small building, it is highly desired to increase the total floor area in the building with a multi-layer structure, or to efficiently arrange living rooms and stairs to expand living space.

  For example, in a house that is built on a narrow, narrow land in a plan view, the width of the room is expanded to the width of the short direction of the house to form a wide space with a sense of openness. It is desirable to form a space.

The following Patent Document 1 discloses a house having a substantially rectangular shape in a plan view, and the central portion of the house and one end side along the short direction of the house are orthogonal to the longitudinal direction of the house A U-shaped staircase is provided. In addition, on the other end side opposite to the one end side provided with the U-shaped staircase, rooms such as a dining room and a washroom are formed.
Japanese Patent Application Laid-Open No. 11-22211

  According to the above-mentioned prior art, since the step portion is folded back in a U-shape, the space of the step portion in the longitudinal direction of the house becomes larger than in the case of forming the straight step. Therefore, the space in which the width of the living room can be expanded to the full width of the short direction of the house becomes smaller. In addition, in a house provided on a narrow narrow land, it is difficult to secure a space that can be used as a living room on the other end side opposite to one end side in the short direction of the house provided with a U-shaped staircase. There is a risk that the limited space can not be used efficiently.

  SUMMARY OF THE INVENTION In view of the above-described facts, the present invention aims to expand a living space, for example, in a multi-story narrow building provided on a narrow narrow land.

And the stairway opening 66 and the laundry space 68 are divided by the side wall 66A. The height of the side wall 66A is set to, for example, approximately half the height from the floor plate (symbols omitted) to the ceiling plate (symbols omitted) of the third floor portion 20, and the light from the roof balcony 69 It is excellent in sex.

  (Action / effect)

  Next, the operation and effects of the first embodiment will be described.

  In the house 10 which concerns on this embodiment, it is formed in substantially rectangular shape by planar view, and is provided with the building main body 12 made into multiple floors.

  In this case, it is necessary to form a staircase connecting the lower floor and the upper floor. Here, in the house 100 shown in FIG. 9, a U-shaped staircase 102 is formed at one side in the short direction of the house 100 with the direction perpendicular to the longitudinal direction of the house 100 as the elevating direction. In this case, since the U-shaped staircase 102 is structured to be bent in a substantially U-shape in plan view, the space occupied by the U-shaped staircase 102 in the longitudinal direction of the house 100 is increased. Therefore, the space which can expand the width of the living room to the full width in the short direction of the house 100 is reduced.

  By the way, securing a space where the width of the room can be expanded to the full width of the short direction of the house 100 is an important theme especially when the house 100 is a narrow building provided on a narrow narrow land. It becomes. The reason is that such a small building is already small in size in the short direction of the building, so when creating a large living room such as a living room or dining room, it is necessary to widen the room fully along the short direction of the building. It is desirable.

  When the U-shaped staircase 102 is provided, as shown in FIG. 9, one side opposite to the one side of the housing 100 in which the U-shaped staircase 102 is formed becomes a dead space. Sometimes limited floor space can not be used efficiently.

  Also, in the house 100, the dining 104 is formed on the front side of the house 100 with the U-shaped staircase 102 in between, and the living 106 is formed on the far side of the house 100. Can see most of the rooms of each other. For this reason, the privacy of each living room may not be ensured, and the whole floor may be given a cluttered impression.

  On the other hand, in the present embodiment, as shown in FIGS. 4 to 5, in the building body 12, a direction substantially orthogonal to the longitudinal direction of the building body 12 is the elevation direction, and the lower floor and the upper floor A straight staircase 30 connecting the two straightly is disposed. Thereby, the space of the stairs which occupies in the longitudinal direction of the building body 12 can be reduced. Therefore, the living space of the house 10 can be expanded first at this point.

  Furthermore, as shown in FIG. 4, in the second floor portion 18 of the house 10, the second stairs 30B are formed in a substantially central portion in the longitudinal direction of the building main body 12 in plan view, so A second staircase 30B linearly connecting serves as a partition between the dining room 54 and the living room 56. As a result, it is possible to omit the space, such as a corridor, which is conventionally required when separately providing a partition wall between the stairs and the living room, and thus the living space of the house 10 can be further expanded. In addition, building materials can be reduced as compared with the case of separately providing partition walls.

  That is, in the house 10 which concerns on this embodiment, it can be said that the function which performs space partitioning is added structurally to the stairs as a means to move each floor in a multi-storey building. As a result, it is possible to reduce the restriction that the stairs have on the floor space in the building, and to omit the space for providing the partition wall which divides the stairs and the living space. As a result, in the house 10 provided on a narrow and narrow land, a room can be efficiently formed, and a wide space can be secured in which the width in the short direction of the building body 12 can be the width of the room. be able to.

  Further, in the present embodiment, the first step 30A and the second step 30B which are configured by the plurality of building units 14 made of steel and configure the straight stairs 30 are one building unit 14 in a plan view. It is formed inside. Moreover, these are each formed in the inside of one building unit, and have connected the lower floor and the upper floor linearly. That is, since the straight stairs 30 requiring high assembly accuracy can be produced in advance in the factory for each building unit, the construction period of the house 10 is completed, and depending on the environment of the construction site, the quality of the stairs is Variation is prevented from occurring. Furthermore, it becomes easy to perform construction work in a narrow building site where it is difficult to secure a place for temporary placement of building materials.

  Further, as shown in FIG. 4, in the second floor portion 18 of the house 10, since the side wall portions 70 are provided on both sides in the longitudinal direction of the building main body 12 in the second step 30B, the second step 30B is used for dining The effect of partitioning between 54 and the living room 56 is improved.

  Here, since the side wall portion 70 is composed of a lattice-shaped lattice wall 72 and a waist wall 78 of a predetermined height erected vertically upward from the floor plate (reference numeral omitted) of the second floor portion 18, For example, a resident who is on the dining 54 side across the second step 30B can visually recognize a part of the living room 56 through the side wall 70. Further, elevator ports 40B and 40C are respectively formed on both sides of the building main body 12 in plan view of the second stairs 30B in the short direction, and the dining room 54 and the living room 56 are communicated through the elevator ports 40B and 40C.
