Description

  The present invention relates to a building such as a house.

In recent years, the construction of houses has been industrialized. For example, in prefabricated houses, rectangular plates such as floor panels, wall panels, roof panels, etc. manufactured in advance without using columns, beams, etc. There is known a construction method (hereinafter referred to as a panel construction method) for forming floors, walls, ceilings, and the like by arranging shaped panels.
Panels for floors, walls, roofs, etc. assembled at the factory are brought to the construction site by trucks. In a construction site, a basic structure of a house such as a floor, a wall, and a roof can be constructed in a short period of time simply by arranging the panels and joining the panels.
In a house constructed with a panel method, for example, when a wide opening is required, such as a garage under a house, a gate consisting of a beam extending horizontally and pillars extending vertically downward from both ends of the beam A mold panel is applied. In addition, there is a type using a gate-type panel unit in which a pair of portal panels are opposed to each other at a predetermined interval, both pillar portions are coupled by wall panels, and beam portions are coupled by floor panels (for example, patents). Reference 1).

Japanese Patent No. 2565626

By the way, when living in a completed house for a long period of time, it is necessary to change the layout and specifications for the growth and independence of the family. For this reason, a house has been designed in which a large space for a room is provided in advance, and a partition wall for non-bearing walls is provided therein so that the floor plan can be easily changed even after completion.
However, if a large room space is provided in accordance with a load-bearing wall such as an outer wall, the amount of the wall decreases, so the structural strength of the building may decrease. On the other hand, in order to improve the structural strength of the building, if bearing walls are provided in various places, not only a large room space cannot be provided in the building, but also the live activity line becomes complicated or In some cases, it becomes limited, and for example, efficient movement for housework becomes impossible.
In general, in a building such as a house, there is a demand not only for the above-described demand but also for improving the solar radiation adjustment such as lighting and shading, and for improving the ventilation.
Therefore, development of a technology that can maintain the necessary structural strength and can provide a large room space in accordance with the load-bearing wall is highly desired, while comprehensively considering the formation of a comfortable living environment. It was rare.

  An object of the present invention is to provide a building capable of maintaining a necessary structural strength and capable of providing a large room space in accordance with a load-bearing wall while comprehensively considering the formation of a comfortable living environment. The purpose is to provide.

In the invention according to claim 1, for example, as shown in FIGS. 1 and 2, a building body 1 having an upper floor and a lower floor is divided into a first area 1a having a rectangular shape in plan view, and the first area 1a. In a building constituted by the second region 1b that is arranged adjacent to and has a rectangular shape in plan view,
The building body 1 includes a recess 2 located at one corner C1 of the building body 1,
The concave portion 2 is arranged such that the main daylighting surface S2 of the second region 1b is set back with respect to the main daylighting surface S1 of the first region 1a, and the outer walls 10, 20 of the first region 1a, which is a load bearing wall. And the outer walls 30, 40 of the second region 1b, which are load bearing walls, are formed in an L shape in plan view by being orthogonal to each other,
Between the first area 1a and the second area 1b of the lower floor, the load bearing wall 14 arranged on the same straight line as the outer wall 10 of the first area 1a forming the recess 2 forms the recess 2. To the outer wall 10 of the first region 1a and the outer walls 13, 32 of the first and second regions 1a, 1b arranged to face the main lighting surfaces S1, S2 of the first and second regions 1a, 1b. It is erected at a predetermined interval from
The first area 1a on the lower floor includes a shared living space including a living room 50, a kitchen 51, a dining 52, and the like, and a stairway 53 that is arranged in accordance with the load-bearing wall 14 and communicates the upper floor and the lower floor. Have

According to the first aspect of the present invention, the main lighting surface S2 of the second region 1b is disposed so as to recede from the main lighting surface S1 of the first region 1a, and the first region is a bearing wall. The outer walls 10 and 20 of 1a and the outer walls 30 and 40 of the second region 1b, which is a load bearing wall, are orthogonal to each other to form a L-shaped recess 2 in plan view. The load-bearing wall 14 arranged on the same straight line as the outer wall 10 of the first region 1a that forms the recess 2 between the region 1a and the second region 1b is the outer wall of the first region 1a that forms the recess 2 10 and a predetermined distance from the outer walls 13 and 32 of the first and second regions 1a and 1b disposed opposite to the main lighting surfaces S1 and S2 of the first and second regions 1a and 1b. Since it is erected, the outer walls 10, 20, 30 as the load-bearing walls 40 and the load-bearing wall 14 can maintain necessary structural strength, and the first region 1a and the first region 1a can be formed without forming a wall that blocks the view between the first region 1a and the lower floor room 64. The lower floor room 64 can be communicated.
For example, in the case of a rectangular building in plan view that does not have the concave portion 2, in order to maintain the required structural strength, a load bearing wall is provided on the outer wall on the main lighting surface side so as to be orthogonal, and the T shape in plan view. However, if a T-shaped wall in plan view is formed in this way, the room inside the building is necessarily partitioned by the wall, and the field of view is blocked. In addition, there is a restriction that the floor plan must be considered based on this wall.
Therefore, a wall that blocks the field of view is formed between the first region 1a and the lower floor room 64 while maintaining the necessary structural strength by the outer walls 10, 20, 30, and 40 that are the bearing walls. Moreover, a large room space can be formed on the lower floor of the building body 1 by communicating the first area 1a with the lower floor room 64.

It is possible to easily go back and forth between them and secure a live activity line that can be moved efficiently.
Furthermore, since the wind taken in from any direction of the building can be circulated through the circulation passage 70, the ventilation between the shared living space and the shared facility space can be improved with certainty.
In addition, since the main lighting surface S2 is disposed so as to recede from the main lighting surface S1, the main lighting surface S2 is more likely to be shaded than the main lighting surface S1. That is, the lower floor room 64 arranged facing the concave portion 2 has higher light shielding performance than the room arranged on the main lighting surface S1 side of the first area 1a, and the main lighting of the first area 1a. The room arranged on the surface S1 side has higher daylighting performance than the lower floor room 64. Therefore, for example, the habitability of the lower floor room 64 can be improved in the summer, and the habitability of the room arranged on the main lighting surface S1 side of the first region 1a can be improved in the winter.
This makes it possible to maintain the necessary structural strength in a comprehensive manner while taking into account the formation of a comfortable living environment. The floor plan in the building body can be easily changed.

  In addition, as shown in FIG. 2, a circulation passage 80 is also arranged around the load bearing wall 24 and the opening 26 on the upper floor. As with the circulation passage 70, the circulation passage 80 can be turned clockwise or counterclockwise, and a door or a partition wall is provided as appropriate.

Furthermore, in the first area 1a and the second area 1b on the upper floor, rooms 55 to 57, 65, and 66 are disposed so as to be adjacent to the circulation passage 80.
That is, in the present embodiment, as shown in FIG. 2, a room 55 is disposed on the main lighting surface S1 side of the first region 1a, and a room 56 is disposed adjacent to the room 55. A toilet 57 is disposed between 56 and the outer wall 23.
Further, a room 65 is disposed on the side of the main lighting surface S2 of the second region 1b, and a walk-in closet 66 is disposed on the side of the outer wall 42 facing the outer wall 40 of the main lighting surface S2. The room 65 and the walk-in closet 66 are not separated by a door.

  In addition, it arrange | positions on the same straight line as the outer wall 40 and the load-bearing wall 24 of the 1st area | region 1a which forms the said recessed part between the room 55 of the said 1st area | region 1a, and the room 65 of the said 2nd area | region 1b. The load bearing wall 27 is erected so as to be separated from the load bearing wall 24 by a predetermined distance from the outer wall 40 of the first region 1 a forming the recess.

Moreover, as shown in FIG. 1, the recessed part 2 located in the lower floor of the said building main body 1 is provided with the wood deck 3 projected ahead from the outer wall 30 of the main lighting surface S2 of the said 2nd area | region 1b.
Further, as shown in FIG. 2, the recess 2 located on the upper floor of the building body 1 is located above the wood deck 3 and from the outer wall 30 of the main lighting surface S2 of the second region 1b. A balcony floor 4 projecting forward from the outer wall 11 of the main lighting surface S1 of the first region 1a is provided.
The balcony floor 4 is supported at its lower end by a column 4 a embedded in the site so as to penetrate the wood deck 3.

According to the present embodiment, the main daylighting surface S2 of the second region 1b is disposed so as to recede from the main daylighting surface S1 of the first region 1a, and the outer wall of the first region 1a that is a load bearing wall 10 and 20 and the outer walls 30 and 40 of the second region 1b, which are load-bearing walls, are orthogonal to each other to form the L-shaped concave portion 2 in plan view, so that the outer walls 10, 20, 30 and 40 can maintain the necessary structural strength, and the first region 1a and the lower floor room 64 can be formed without forming a wall that blocks the field of view between the first region 1a and the lower floor room 64. Can communicate with each other.
For example, in the case of a rectangular building in plan view that does not have the concave portion 2, in order to maintain the required structural strength, a load bearing wall is provided on the outer wall on the main lighting surface side so as to be orthogonal, and the T shape in plan view. However, if a T-shaped wall in plan view is formed in this way, the room inside the building is necessarily partitioned by the wall, and the field of view is blocked. In addition, there is a restriction that the floor plan must be considered based on this wall.
Therefore, a wall that blocks the field of view is formed between the first region 1a and the lower floor room 64 while maintaining the necessary structural strength by the outer walls 10, 20, 30, and 40 that are the bearing walls. Moreover, a large room space can be formed on the lower floor of the building body 1 by communicating the first area 1a with the lower floor room 64.

  In addition, the load-bearing wall 14 is erected between the first region 1a and the second region 1b on the lower floor with a predetermined distance from the outer wall 10 and the outer walls 13 and 32. In addition, since a circulation passage 70 is provided around the bearing wall 14 and the stairs 53 to connect the shared living space and the shared equipment space, the shared living space and the shared equipment space are connected through the circular passage 70. It is possible to easily go back and forth between them and secure a live activity line that can be moved efficiently.

  Furthermore, since the wind taken in from any direction of the building can be circulated through the circulation passage 70, the ventilation between the shared living space and the shared facility space can be improved with certainty.

  In addition, since the main lighting surface S2 is disposed so as to recede from the main lighting surface S1, the main lighting surface S2 is more likely to be shaded than the main lighting surface S1. That is, the lower floor room 64 arranged facing the concave portion 2 has higher light shielding performance than the room arranged on the main lighting surface S1 side of the first area 1a, and the main lighting of the first area 1a. The room arranged on the surface S1 side has higher daylighting performance than the lower floor room 64. Therefore, for example, the habitability of the lower floor room 64 can be improved in the summer, and the habitability of the room arranged on the main lighting surface S1 side of the first region 1a can be improved in the winter.

  Moreover, since the utility part 54 used as a multipurpose space for hobbies, housework, etc. is arranged on the circuit 70, for example during cooking or washing, the shared living space or shared equipment space is more than necessary. The utility unit 54 can perform work related to other housework and hobbies without leaving. Furthermore, since it becomes possible to easily go back and forth between the shared living space and the shared equipment space including the utility unit 54, a live activity line that can move more efficiently can be secured.

  In the second area 1b, an entrance 60 is disposed on the lower floor room 64 side. In the first area 1a, a living room 50 is disposed on the main lighting surface S1 side, and the main lighting surface. A kitchen 51 is arranged in accordance with the outer wall 13 facing S1, and a dining 52 is arranged between the living room 50 and the kitchen 51, and the ascending entrance of the stairs 53 is the dining 52 in the first area 1a. Since it is located in the vicinity, in order to reach the ascending entrance of the staircase 53 from the entrance 60, the user always enters the first region 1a. Thereby, the opportunity of communication between residents can be increased reliably.

In addition, the load-bearing wall 24 is erected between the first region 1a and the second region 1b on the upper floor with a predetermined distance from the outer wall 20 and the outer walls 23 and 42. In addition, since the circulation passage 80 is disposed around the bearing wall 24 and the opening 26, the first floor 1a and the second region 1b on the upper floor can be easily traversed through the circulation passage 80. Thus, even on the upper floor of the building body 1, a live activity line that can be moved efficiently can be secured.
Furthermore, since the rooms 55, 56, 57, 65, 66 are arranged in the first area 1 a and the second area 1 b on the upper floor so as to be adjacent to the circulation path 80, through the circulation path 80, It becomes possible to easily go back and forth between the rooms 55, 56, 57, 65, 66.
Moreover, since the wind taken in from any direction of the building can be circulated through the circulation passage 80, the air permeability between the first area 1a and the second area 1b on the upper floor is reliably improved. be able to. Furthermore, the ventilation between the upper and lower floors can be improved through the opening 26 of the upper floor.

Moreover, it protrudes ahead from the outer wall 30 of the main lighting surface S1 of the said 1st area | region 1a from the outer wall 30 of the main lighting surface S2 of the said 2nd area | region 1b to the recessed part 2 located in the upper floor of the said building main body 1. Since the balcony floor 4 is provided, the balcony floor 4 can reliably block the solar radiation below the balcony floor 4. Thereby, in summer, for example, the comfortability of the lower floor room 64 arranged facing the recess 2 can be further improved.
Further, since the balcony floor 4 can be reduced in the forward projecting dimension compared to the case where the balcony floor 4 is provided so as to project forward in a portion that is not the concave portion 2, for example, in a narrow site in an urban area. Can also be supported.

  This makes it possible to maintain the necessary structural strength in a comprehensive manner while taking into account the formation of a comfortable living environment. The floor plan in the building body can be easily changed.
