Description

The present invention relates to a building structure that includes a building section having a room that is rectangular or approximately rectangular in plan view.

In building structures having building sections such as wall structures constructed of slabs and earthquake-resistant walls (wall columns) (see, for example, Patent Documents 1 and 2), earthquake resistance is ensured by arranging earthquake-resistant walls that extend in at least two directions that are perpendicular in a plan view.
In building sections such as wall structures in which rectangular or approximately rectangular rooms with simple shapes and easy to use are arranged in succession, earthquake-resistant walls extending in a direction perpendicular to the extension direction of the outdoor side of the rooms in a planar view are generally arranged in the partition walls between adjacent rooms in order to resist earthquake forces in a direction perpendicular to the extension direction of the outdoor side of the rooms in a planar view, and earthquake-resistant walls extending in the extension direction of the outdoor side of the rooms in a planar view are arranged in the wall portions of the outdoor sides of the rooms, etc. in order to resist earthquake forces in the extension direction of the outdoor side of the rooms in a planar view.

Patent No. 6463901 Patent No. 6482887

In the above conventional building structure, although the room shape is simple and easy to use, the earthquake-resistant wall that resists earthquake forces in the extension direction of the outdoor side of the room occupies part of the wall on the outdoor side of the room, making it difficult to secure a large opening area on the outdoor side of the room, and the room tends to become a closed space.

In light of this situation, the main objective of the present invention is to provide a technology that can create an open living space by making the opening area on the outdoor side of a room large in a building structure that includes a building section having a room that is rectangular or approximately rectangular in plan view.

The present invention is provided with a building portion having a room that is rectangular or approximately rectangular in plan view,
It is preferable that the earthquake-resistant wall of the building portion be an oblique earthquake-resistant wall extending in a direction that intersects obliquely with the extension direction of the outdoor side of the living space in a plan view, and that the oblique earthquake- resistant wall is arranged in the outer portion of the outdoor side of the living space in the building portion.

In other words, the diagonal earthquake-resistant wall extending in a direction that crosses the extension direction of the outdoor side surface of the living room in a plan view has a lower resistance efficiency than the earthquake-resistant wall extending in the extension direction of the outdoor side surface of the living room in a plan view, but can resist the earthquake force in the extension direction of the outdoor side surface of the living room. According to this configuration, by arranging the diagonal earthquake-resistant wall in such an oblique posture to resist the earthquake force in the direction perpendicular to the extension direction of the outdoor side surface of the living room, for example, in the partition wall portion between the living rooms, the earthquake-resistant wall and the earthquake-resistant wall extending in the direction perpendicular to the extension direction of the outdoor side surface of the living room can cooperate to appropriately ensure the earthquake resistance performance of the building part. And, since the diagonal earthquake-resistant wall that resists the earthquake force in the extension direction of the outdoor side surface of the living room is arranged in the outer part of the outdoor side surface of the living room in the building part, it is possible to prevent the earthquake-resistant wall that resists the earthquake force in the extension direction of the outdoor side surface of the living room from occupying the wall part of the outdoor side surface of the living room.
Therefore, in a building structure that has a building section with a room that is rectangular or approximately rectangular in plan view, it is possible to provide a technology that can increase the opening area on the outdoor side of the room, creating an open living space.

In the present invention, it is preferable that the oblique attitude of the oblique earthquake-resistant wall is set to an attitude in which the wall surface faces an object to be blocked.

With this configuration, the diagonal earthquake-resistant wall is set in a position that faces the wall surface toward the object to be blocked, so that the view from the living room in the extension direction of the diagonal earthquake-resistant wall is secured, while the object to be blocked is appropriately blocked, preventing the object from reaching the inside of the living room.

In the present invention, it is preferable that the object to be blocked is a line of sight from an adjacent building portion adjacent to the building portion.

With this configuration, the diagonal earthquake-resistant wall can adequately block views from adjacent buildings, ensuring privacy within the room.

A first characteristic configuration of the present invention is a building portion having a room that is rectangular or approximately rectangular in plan view,
As a seismic wall of the building section, an oblique seismic wall extending in a direction obliquely intersecting with an extension direction of the outdoor side surface of the living room in a plan view is disposed in an outer portion of the outdoor side surface of the living room in the building section,
The adjacent building portion adjacent to the building portion is arranged in a state in which it extends along a direction intersecting the building portion in a plan view,
The inclined earthquake-resistant wall is arranged in an oblique position extending at an intermediate angle between the intersection angle between the building portion and the adjacent building portion in a plan view, on the side of the building portion facing the outdoor space surrounded by the building portion and the adjacent building portion.

According to this configuration, the shape of a building consisting of a building portion and an adjacent building portion can be made L-shaped or cross-shaped, which makes it easy to arrange earthquake-resistant walls in two directions, making it easier to ensure earthquake resistance.
Furthermore, the diagonal earthquake-resistant wall is arranged in a diagonal position at an intermediate angle (e.g., 30 degrees to 60 degrees) between the intersection angle (e.g., 90 degrees) between the building part and the adjacent building part in a plan view, on the side of the outdoor space surrounded by the building part and the adjacent building part.Therefore, it is possible to ensure a view to the outdoor space side, which is the extension direction of the diagonal earthquake-resistant wall, while blocking the view from the adjacent building part, thereby ensuring good privacy within the living room.

A second characteristic configuration of the present invention is a building portion having a room that is rectangular or approximately rectangular in plan view,
As a seismic wall of the building section, an oblique seismic wall extending in a direction obliquely intersecting with an extension direction of the outdoor side surface of the living room in a plan view is disposed in an outer portion of the outdoor side surface of the living room in the building section,
The inclined earthquake-resistant wall is disposed so as to extend outward from a middle portion of the exterior side surface of the living room in an extension direction,
The air supply section that supplies air to the living space and the exhaust section that exhausts air from the living space are arranged separately at one end and the other end in the extension direction of the outdoor side of the living space, with the connection part of the inclined earthquake-resistant wall on the outdoor side of the living space as the boundary.

According to this configuration, the diagonal earthquake-resistant wall is arranged to extend outward from the middle of the extension direction of the outdoor side of the living room, which can prevent short circuits between the air intake section and the exhaust section that are arranged separately at one end side and the other end side of the extension direction of the outdoor side of the living room, separated by the connection part of the diagonal earthquake-resistant wall on the outdoor side of the living room, and can provide good ventilation of the living room through the air intake section and the exhaust section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a building structure according to the present invention will be described with reference to the drawings.
As shown in Fig. 1, building B in which this building structure is adopted is constructed of a wall structure such as reinforced concrete construction in which earthquake-resistant walls (wall columns) 1 that bear vertical and horizontal forces are arranged between the slabs of each floor, and is constructed as a mid- to high-rise dormitory or apartment building with many rooms 2 such as dormitory rooms and dwelling units on each floor. In Fig. 1, the earthquake-resistant walls 1 are shown by thick solid lines. In the following explanation, the left-right direction in Fig. 1 is defined as the X direction, and the up-down direction is defined as the Y direction.

This building B is provided with first to fourth building sections b1 to b4 as multiple residential building sections Ba in which many rooms 2 are arranged consecutively in the longitudinal direction. In addition, between the first to fourth building sections b1 to b4, a fifth building section b5 is provided as a common space building section Bb in which a common space for residents is arranged.

Specifically, on the Y1 side of building B (upper side in the figure), a first building section b1 whose longitudinal direction is in the X direction and a second building section b2 whose longitudinal direction is in the Y direction are arranged in a left-right inverted L-shape when viewed in a plan view, forming a modified L-shaped building section.
In addition, on the Y2 side of building B (lower side in the figure), a third building section b3 whose longitudinal direction is in the X direction and a fourth building section b4 whose longitudinal direction is in the Y direction are arranged in a state in which the letter L is inverted upside down when viewed in a plan view, forming a modified L-shaped building section.
The fifth building section b5, which is rectangular in plan view, is positioned between the modified L-shaped building section consisting of the first building section b1 and the second building section b2, and the modified L-shaped building section consisting of the third building section b3 and the fourth building section b4, connecting and integrating both modified L-shaped building sections.
Therefore, this building B is constructed with a well-balanced planar shape that is point-symmetric or approximately point-symmetric, with the center of rigidity and center of gravity approximately coinciding when viewed from above.

As shown in Figure 2, in each residential building section Ba (first to fourth building sections b1 to b4), a number of rooms 2 are arranged in two rows on either side of the corridor 3 in the short direction (up and down direction in Figure 2), and are arranged consecutively in the longitudinal direction (left and right direction in Figure 2). In this embodiment, each room 2 is configured to be rectangular in plan view. Incidentally, the shape of the room 2 in plan view may have a concave or convex part on a very small part of the outer periphery, or part of the outer periphery may be slightly curved, as long as it is approximately rectangular in plan view.

In addition, in the partition wall portion 21 between the living rooms 2, a non-diagonal earthquake-resistant wall 11 is arranged as an earthquake-resistant wall 1, which extends in a direction perpendicular to the extension direction of the outdoor side surface 22 of the living room 2 in a plan view (the longitudinal direction of the residential building section Ba, the girder direction) in a plan view. In addition, in the outer portion of the outdoor side surface 22 of the living room 2 (the outer portion open to the outdoor space), an oblique earthquake-resistant wall 12 is arranged as an earthquake-resistant wall 1, which extends in a direction that intersects obliquely with the extension direction of the outdoor side surface 22 of the living room 2 in a plan view (a direction that intersects at an angle other than 90 degrees).

Since such an obliquely oriented diagonal earthquake-resistant wall 12 can resist earthquake forces in the extension direction of the outdoor side surface 22 of the living room 2 in a plan view, it can cooperate with the non-diagonal earthquake-resistant wall 11 extending in a direction perpendicular to the extension direction of the outdoor side surface 22 of the living room 2 in a plan view to ensure appropriate earthquake resistance performance. Furthermore, since this oblique earthquake-resistant wall 12 is arranged in the outer part of the outdoor side surface 22 of the living room 2 in each residential building section Ba, it is possible to prevent the earthquake-resistant wall 1 from occupying the wall part of the outdoor side surface 22 of the living room 2, and it is possible to create an open living space by making the opening area of the outdoor side surface 22 of the living room 2 large. Incidentally, this oblique earthquake-resistant wall 12 is also arranged in the outer part of the common space building section Bb (fifth building section b5) as shown in FIG. 1.

Returning to FIG. 1, in the first to fifth building sections b1 to b5, the orientation of the diagonal earthquake-resistant walls 12 is set so that the wall faces toward the line of sight from the adjacent building section (an example of an object to be blocked). Specifically, the diagonal earthquake-resistant walls 12 are arranged on the outdoor space side of the building section surrounded by the building section in question and the adjacent building section, in an oblique orientation extending at an intermediate angle (0 degrees < intermediate angle < intersection angle α) between the building section in question in plan view and the intersection angle α between the adjacent building section in question and the building section in question that is arranged to extend in a direction that intersects with the building section in plan view.

Specifically, on one side of the short side of the first building part b1 (upper side, Y1 side in the figure) whose longitudinal direction is the X direction, the second building part b2 whose longitudinal direction is the X direction is adjacent at an intersection angle α (α1: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S1 side surrounded by the first building part b1 and the second building part b2 in an oblique posture extending at an angle of 45 degrees (the central angle of the intersection angle α) to the X1 side and the Y1 side (upper left in the figure) as an intermediate angle between the intersection angles α. Therefore, on one side of the short side of this first building part b1, while ensuring a view to the outdoor space S1 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outline arrow), the wall surface of the diagonal earthquake-resistant wall 12 can block the view from the second building b2, ensuring good privacy in the living room 2.

In addition, on the other side of the short side of the first building part b1 (the lower side in the figure, the Y2 side), the fifth building part b5 and the fourth building part b4 are adjacent with an intersection angle α (α2: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S2 side surrounded by the first building part b1, the fifth building part b5, and the fourth building part b4 in an oblique posture extending at an angle of 45 degrees to the X1 side and the Y2 side (lower left in the figure) as an intermediate angle between the intersection angles α. Therefore, on the other side of the short side of the first building part b1, the view to the outdoor space S2 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outlined arrow), is secured, while the wall surface of the diagonal earthquake-resistant wall 12 can block the view from the fifth building part b5 and the fourth building part b4, ensuring good privacy in the living room 2.

On one side of the short side of the second building part b2 (left side in the figure, X1 side), the first building part b1 is adjacent at an intersection angle α (α1: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S1 side surrounded by the first building part b1 and the second building part b2 in an oblique position extending at an angle of 45 degrees to the X1 side and the Y1 side (upper left in the figure) as an intermediate angle between the intersection angles α. Therefore, on one side of the short side of this second building part b2, while ensuring a view (see the white arrow) to the outdoor space S1 side, which is the extension direction of the diagonal earthquake-resistant wall 12, the wall surface of the diagonal earthquake-resistant wall 12 can block the view from the first building part b1, ensuring good privacy within the living room 2.

In addition, on the other short-side side (right side in the figure, X2 side) of the second building part b2, the fifth building part b5 and the third building part b3 are adjacent with an intersection angle α (α3: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S3 side surrounded by the second building part b2, the fifth building part b5, and the third building part b3 in an oblique position extending at an angle of 45 degrees to the X2 side and the Y1 side (upper right in the figure) as an intermediate angle between the intersection angles α. Therefore, on the other short-side side of this second building part b2, the view to the outdoor space S3 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outlined arrow), is secured, while the wall surface of the diagonal earthquake-resistant wall 12 can block the view from the fifth building part b5 and the third building part b3, ensuring good privacy in the living room 2.

On one side of the short side of the third building section b3 (upper side in the figure, Y1 side) with the X direction as the longitudinal direction, the fifth building section b5 and the second building section b2 are adjacent with an intersection angle α (α3: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S3 side surrounded by the third building section b3, the fifth building section b5, and the second building section b2 in an oblique position extending at an angle of 45 degrees to the X2 side and the Y1 side (upper right in the figure) as an intermediate angle between the intersection angles α. Therefore, on one side of the short side of this third building section b3, the view to the outdoor space S3 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outlined arrow), is secured, while the wall surface of the diagonal earthquake-resistant wall 12 blocks the view from the fifth building section b5 and the second building section b2, ensuring good privacy in the living room 2.

In addition, on the other short-side side (lower side, Y2 side in the figure) of the third building section b3, the fourth building section b4 is adjacent at an intersection angle α (α4: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S4 side surrounded by the third building section b3 and the fourth building section b4 in an oblique position extending at an angle of 45 degrees to the X2 side and the Y2 side (lower right in the figure) as an intermediate angle between the intersection angles α. Therefore, on the other short-side side of this third building section b3, while ensuring a view (see the white arrow) to the outdoor space S4 side, which is the extension direction side of the diagonal earthquake-resistant wall 12, the wall surface of the diagonal earthquake-resistant wall 12 can block the view from the fourth building section b4, ensuring good privacy in the living room 2.

On one side of the short side of the fourth building section b4 (left side in the figure, X1 side), whose longitudinal direction is the Y direction, the fifth building section b5 and the first building section b1 are adjacent to each other at an intersection angle α (α2: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S2 side surrounded by the fourth building section b4, the fifth building section b5, and the first building section b1 in an oblique position extending at an angle of 45 degrees to the X1 side and the Y2 side (lower left in the figure) as an intermediate angle between the intersection angles α. Therefore, on one side of the short side of this fourth building section b4, the view to the outdoor space S2 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outlined arrow), is secured, while the wall surface of the diagonal earthquake-resistant wall 12 blocks the view from the fifth building section b5 and the first building section b1, ensuring good privacy in the living room 2.

In addition, on the other short-side side (right side in the figure, X2 side) of the fourth building section b4, the third building section b3 is adjacent at an intersection angle α (α4: 90 degrees in the illustrated example), so the diagonal earthquake-resistant wall 12 is arranged on the outdoor space S4 side surrounded by the fourth building section b4 and the third building section b3 in an oblique position extending at an angle of 45 degrees to the X2 side and the Y2 side (lower right in the figure) as an intermediate angle between the intersection angles α. Therefore, on the other short-side side of this fourth building section b4, while ensuring a view (see the white arrow) to the outdoor space S4 side, which is the extension direction of the diagonal earthquake-resistant wall 12, the wall surface of the diagonal earthquake-resistant wall 12 can block the view from the third building section b3, ensuring good privacy in the living room 2.

Similarly, on the X1 side (left side in the figure) and Y2 side (lower side in the figure) of the fifth building section b5, it is arranged on the outdoor space S2 side surrounded by the fifth building section b5, the first building section b1, and the fourth building section b4, in a diagonal posture extending at an angle of 45 degrees to the X1 side and the Y2 side (lower left in the figure) as an intermediate angle with respect to the intersection angle α (α2: 90 degrees in the illustrated example) with the adjacent building sections (the first building section b1 and the fourth building section b4). Therefore, on the X1 side and Y2 side of this fifth building section b5, the view to the outdoor space S2 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outline arrow), can be secured, while the wall surface of the diagonal earthquake-resistant wall 12 can block the line of sight from the adjacent building sections (the first building section b1 and the fourth building section b4).

In addition, on the X2 side (right side in the figure) and Y1 side (upper side in the figure) of the fifth building section b5, it is arranged on the outdoor space S3 side surrounded by the fifth building section b5, the second building section b2, and the third building section b3 in a diagonal posture extending at an angle of 45 degrees to the X2 side and the Y1 side (upper right in the figure) as an intermediate angle with respect to the intersection angle α (α3: 90 degrees in the illustrated example) with the adjacent building sections (the second building section b2 and the third building section b3). Therefore, on the X2 side and Y1 side of this fifth building section b5, the view to the outdoor space S3 side, which is the extension direction side of the diagonal earthquake-resistant wall 12 (see the outline arrow), can be secured, while the wall surface of the diagonal earthquake-resistant wall 12 can block the line of sight from the adjacent building sections (the second building section b2 and the third building section b3).

Next, the arrangement of the diagonal earthquake-resistant walls 12 in each residential building section Ba will be described.
As shown in Fig. 2, the diagonal earthquake-resistant walls 12 are arranged at a predetermined pitch in the extension direction of the outdoor side surface 22 in the outer portion of the outdoor side surface 22 of the living room 2 in each residential building portion Ba. The arrangement pitch of the diagonal earthquake-resistant walls 12 can be set, for example, so as to block the line of sight from all portions of the adjacent building portions.

In this embodiment, two (one example of multiple) diagonal earthquake-resistant walls 12 are arranged corresponding to one living room 2. Of the two diagonal earthquake-resistant walls 12 for each living room 2, one diagonal earthquake-resistant wall 12A is arranged in a state where it extends outward (toward the outdoor space) from the end in the extension direction of the outdoor side surface 22 of the living room 2 in which the non-diagonal earthquake-resistant wall 11 is arranged in the partition wall portion 21. Of the two diagonal earthquake-resistant walls 12 for each living room 2, the other diagonal earthquake-resistant wall 12B is arranged in a state where it extends outward from the middle in the extension direction of the outdoor side surface 22 of the living room 2.

The air supply section 23 that supplies air to the living room 2 and the exhaust section 24 that exhausts air from the living room 2 are arranged separately at one end side and the other end side in the extension direction of the outdoor side surface 22 of the living room 2, with the connection part of the diagonal earthquake-resistant wall 12B on the outdoor side surface 22 of the living room 2 as the boundary. The air supply section 23 and the exhaust section 24 can be configured, for example, by providing an opening or a fan on the outdoor side surface 22.

Therefore, in the outer portion of the outdoor side surface 22 of the living room 2, the intake space to the air supply section 23 and the exhaust space by the exhaust section 24 can be separated by the inclined earthquake-resistant wall 12B, which suppresses short circuits between the air supply section 23 and the exhaust section 24 and allows for good ventilation of the living room 2 by the air supply section 23 and the exhaust section 24.

In addition, in this embodiment, between adjacent living rooms 2 in the extension direction of the outdoor side surface 22, the air intake section 23 of one living room 2 is not adjacent to the air exhaust section 24 of the other living room 2, but the air exhaust sections 24 of both adjacent living rooms 2 are adjacent to each other, so that short circuits between the air intake section 23 of one living room 2 and the air exhaust section 24 of the other living room 2 can also be suppressed. Note that, instead of this, the air intake sections 23 of both adjacent living rooms 2 may be configured to be adjacent to each other.

[Another embodiment]
Other embodiments of the present invention will be described below. Note that the configurations of the embodiments described below are not limited to being applied alone, but may also be applied in combination with the configurations of other embodiments.

(1) In the above embodiment, the present invention is applied to a building B with a wall structure in which the slab and earthquake-resistant wall (wall column) 1 are the main structure, but the present invention may also be applied to buildings with a rigid frame structure in which slabs and earthquake-resistant walls are arranged around columns and beams as the main structure.

(2) In the above embodiment, the oblique earthquake-resistant wall 12 blocks the line of sight from the adjacent building, and the oblique earthquake-resistant wall 12 is set in a position to face the wall surface toward the adjacent building. However, for example, the oblique earthquake-resistant wall 12 may block the western sun, and the oblique earthquake-resistant wall 12 may be set in a position to face the wall surface toward the western sun. The object that the oblique earthquake-resistant wall 12 blocks can be set according to the building use, surrounding environment, etc.
