Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above conventional building structure, although there is an advantage that the shape of the living room is simple and easy to use, since the seismic wall that resists seismic forces in the extending direction of the outdoor side surface of the living room occupies a part of the wall portion of the outdoor side surface of the living room, it is difficult to increase the opening area of the outdoor side surface of the living room, and there is a problem that the living room tends to become a closed space.

[0005] In view of this situation, the main problem of the present invention is to provide a technology that can increase the opening area of the outdoor side surface of a living room and create an open living room space in a building structure provided with a building part having a living room that is rectangular or substantially rectangular in plan view.

Means for Solving the Problems

[0006] The present invention is is provided with a building part having a living room that is rectangular or substantially rectangular in plan view, As a seismic wall of the building part, a diagonal seismic wall extending in a direction obliquely intersecting the extending direction of the outdoor side surface of the living room in plan view is arranged at an outer part of the outdoor side surface of the living room in the building part. suitable with There is.

[0007] That is, although the diagonal seismic wall extending in a direction obliquely intersecting the extending direction of the outdoor side surface of the living room in plan view has a lower resistance efficiency than a seismic wall extending in the extending direction of the outdoor side surface of the living room in plan view, it can resist the seismic force in the extending direction of the outdoor side surface of the living room. According to this configuration, in order to resist the seismic force in the direction orthogonal to the extending direction of the outdoor side surface of the living room, by arranging such a diagonal seismic wall in an oblique posture, for example, at a door boundary wall portion between living rooms, etc., a seismic wall extending in the direction orthogonal to the extending direction of the outdoor side surface of the living room and the diagonal seismic wall cooperate with each other to appropriately ensure the seismic performance of the building part. And, since the diagonal seismic wall that resists the seismic force in the extending direction of the outdoor side surface of the living room is arranged at an outer part of the outdoor side surface of the living room in the building part, it is possible to avoid the seismic wall that resists the seismic force in the extending direction of the outdoor side surface of the living room from occupying the wall portion of the outdoor side surface of the living room. Therefore, in a building structure provided with a building part having a living room that is rectangular or substantially rectangular in plan view, it is possible to provide a technology that can increase the opening area of the outdoor side surface of the living room and create an open living room space.

[0008] The present invention is The diagonal posture of the diagonal seismic wall is set to a posture in which the wall surface faces the object to be blocked. suitable with There is.

[0009] According to this configuration, the diagonal seismic wall set in a posture facing the wall surface with respect to the shielding target can appropriately shield the shielding target while ensuring the view from the living room in the extending direction of the diagonal seismic wall, and suppress the shielding target from reaching the interior of the living room.

[0010] The present invention is wherein the shielding target is a line of sight from an adjacent building part adjacent to the building part suitable with exists.

[0011] According to this configuration, the diagonal seismic wall can appropriately shield the line of sight from the adjacent building part, and can ensure good privacy in the living room.

[0012] The 1 characteristic configuration of the present invention is a building part having a living room that is rectangular or substantially rectangular in plan view is provided, as a seismic wall of the building part, a diagonal seismic wall in a diagonal posture extending in a direction obliquely intersecting the extending direction of the outdoor side surface of the living room in plan view is arranged at an outer part of the outdoor side surface of the living room in the building part, adjacent to the building part wherein the adjacent building part is arranged in a state of extending along a direction intersecting with the building part in plan view, and the diagonal seismic wall is arranged on the outdoor space side surrounded by the building part and the adjacent building part in the building part in a diagonal posture extending at an intermediate angle between the intersection angles of the building part and the adjacent building part in plan view.

[0013] According to this configuration, the shape of the building composed of the building part and the adjacent building part can be made into an L-shape, a cross-shape, etc. where it is easy to arrange seismic walls in two directions, and it is easy to ensure seismic performance. And since the diagonal seismic wall is arranged on the outdoor space side surrounded by the building part and the adjacent building part in the building part in a diagonal posture at an intermediate angle (for example, 30 degrees to 60 degrees) between the intersection angles (for example, 90 degrees) of the building part and the adjacent building part in plan view, while ensuring the view to the outdoor space side on the extending direction side of the diagonal seismic wall, the line of sight from the adjacent building part can be shielded and good privacy in the living room can be ensured.

[0014] The 2 characteristic configuration of the present invention is a building part having a living room that is rectangular or substantially rectangular in plan view is provided, as a seismic wall of the building part, a diagonal seismic wall in a diagonal posture extending in a direction obliquely intersecting the extending direction of the outdoor side surface of the living room in plan view is arranged at an outer part of the outdoor side surface of the living room in the building part, The diagonal seismic wall is arranged so as to extend outward from the middle part in the extending direction of the outdoor side surface of the living room. There is a point that an air supply part for supplying air to the living room and an exhaust part for exhausting air from the living room are separately arranged on one end side and the other end side in the extending direction of the outdoor side surface of the living room with the connection part of the diagonal seismic wall on the outdoor side surface of the living room as a boundary.

[0015] According to this configuration, the diagonal seismic wall arranged so as to extend outward from the middle part in the extending direction of the outdoor side surface of the living room can suppress a short circuit between the air supply part and the exhaust part separately arranged on one end side and the other end side in the extending direction of the outdoor side surface of the living room with the connection part of the diagonal seismic wall on the outdoor side surface of the living room as a boundary, and can perform good ventilation of the living room by the air supply part and the exhaust part.

Embodiments for Carrying Out the Invention

[0017] An embodiment of the building structure of the present invention will be described with reference to the drawings. As shown in FIG. 1, a building B adopting this building structure is configured by a wall type structure such as a reinforced concrete structure in which seismic walls (wall columns) 1 for bearing vertical forces and horizontal forces are arranged between slabs on each floor, and is configured as a mid-rise dormitory or apartment house having a number of living rooms 2 such as dormitory rooms and dwelling units on each floor. In FIG. 1, the seismic walls 1 are shown by thick solid lines. Hereinafter, in FIG. 1, the left-right direction will be referred to as the X direction and the up-down direction will be referred to as the Y direction for explanation.

[0018] The building B is provided with first to fourth building parts b1 to b4 as a plurality of residential building parts Ba in which a large number of living rooms 2 are arranged continuously in the longitudinal direction. Further, between the first to fourth building parts b1 to b4, a fifth building part b5 is provided as a common space building part Bb in which a common space for residents is arranged.

[0019] Specifically, on the Y1 side (upper side in the figure) of the building B, a first building part b1 with the X direction as the longitudinal direction and a second building part b2 with the Y direction as the longitudinal direction are arranged in a state where the L shape is reversed left and right in plan view and configured as a deformed L-shaped building part. Also, on the Y2 side (lower side in the figure) of the building B, a third building part b3 with the X direction as the longitudinal direction and a fourth building part b4 with the Y direction as the longitudinal direction are arranged in a state where the L shape is reversed up and down in plan view and configured as a deformed L-shaped building part. And a fifth building part b5 having a rectangular shape in plan view is arranged between the deformed L-shaped building part composed of the first building part b1 and the second building part b2 and the deformed L-shaped building part composed of the third building part b3 and the fourth building part b4, connecting and integrating both deformed L-shaped building parts. Therefore, this building B is configured in a well-balanced planar shape that is point-symmetric or substantially point-symmetric with the rigid center and the center of gravity substantially coinciding in plan view.

[0020] As shown in FIG. 2, in each residential building part Ba (first to fourth building parts b1 to b4), a large number of living rooms 2 are arranged continuously in the longitudinal direction (left and right direction in FIG. 2) in a two-row arrangement located on both outer sides in the short direction (up and down direction in FIG. 2) with the corridor 3 in between. In this embodiment, each living room 2 is configured to have a rectangular shape in plan view. Incidentally, the shape of the living room 2 in plan view may have concave or convex portions at a very small part of the outer periphery, or a part of the outer periphery may be slightly curved, as long as it is substantially rectangular in plan view.

[0021] And in the door boundary wall portion 21 between the living rooms 2, as a seismic wall 1, a non - diagonal seismic wall 11 extending in a direction orthogonal to the extending direction of the outdoor side surface 22 of the living room 2 (the longitudinal direction of the residential building part Ba, the girder row direction) in plan view is arranged. Also, in the outer part of the outdoor side surface 22 of the living room 2 (the outer part opened to the outdoor space), as a seismic wall 1, a diagonal seismic wall 12 with a diagonal posture extending in a direction obliquely intersecting the extending direction of the outdoor side surface 22 of the living room 2 in plan view (a direction intersecting at an angle other than 90 degrees) is arranged.

[0022] Such a diagonal seismic wall 12 with a diagonal posture can resist the seismic force in the extending direction of the outdoor side surface 22 of the living room 2 in plan view. Therefore, it can cooperate with the non - diagonal seismic wall 11 extending in a direction orthogonal to the extending direction of the outdoor side surface 22 of the living room 2 in plan view to appropriately ensure the seismic performance. And since this diagonal seismic wall 12 is arranged in the outer part of the outdoor side surface 22 of the living room 2 in each residential building part Ba, it is possible to avoid the seismic wall 1 occupying the wall part of the outdoor side surface 22 of the living room 2, and a large opening area of the outdoor side surface 22 of the living room 2 can be taken to create an open living space. Incidentally, as shown in FIG. 1, this diagonal seismic wall 12 is also arranged in the outer part of the building part Bb (the fifth building part b5) for the shared space.

[0023] Returning to FIG. 1, in the first to fifth building parts b1 to b5, the posture of the diagonal seismic wall 12 is set to face the wall surface with respect to the line of sight from the adjacent building part (an example of an object to be blocked). Specifically, the diagonal seismic wall 12 extends in a diagonal posture at an intermediate angle (0 degrees < intermediate angle < intersection angle α) between the building part where it is installed in plan view and the intersection angle α with the adjacent building part extending along the direction intersecting with it in plan view, and is arranged on the outdoor space side surrounded by the building part and the adjacent building part in the building part.

[0024] Specifically, on one side in the short side direction (the upper side in the figure, Y1 side) of the first building part b1 with the X direction as the longitudinal direction, since the second building part b2 with the X direction as the longitudinal direction is adjacent at an intersection angle α (α1: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends in a diagonal posture at an angle of 45 degrees obliquely to the X1 side and the Y1 side (the upper left in the figure) as an intermediate angle between the intersection angles α, and is arranged on the outdoor space S1 side surrounded by the first building part b1 and the second building part b2. Therefore, on one side in the short side direction of this first building part b1, while ensuring a view (refer to the white arrow) to the outdoor space S1 side which is the extending direction side of the diagonal seismic wall 12, the line of sight from the second building b2 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy in the living room 2 can be ensured.

[0025] Also, on the other side in the short side direction (the lower side in the figure, Y2 side) of the first building part b1, since the fifth building part b5 and the fourth building part b4 are adjacent at an intersection angle α (α2: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends in a diagonal posture at an angle of 45 degrees obliquely to the X1 side and the Y2 side (the lower left in the figure) as an intermediate angle between the intersection angles α, and 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. Therefore, on the other side in the short side direction of this first building part b1, while ensuring a view (refer to the white arrow) to the outdoor space S2 side which is the extending direction side of the diagonal seismic wall 12, the line of sight from the fifth building part b5 and the fourth building part b4 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy in the living room 2 can be ensured.

[0026] On one side in the short side direction of the second building part b2 (the left side in the figure, X1 side), since the first building part b1 is adjacent at an intersection angle α (α1: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends obliquely 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, and is arranged on the outdoor space S1 side surrounded by the first building part b1 and the second building part b2. Therefore, on one side in the short side direction of this second building part b2, while securing a view to the outdoor space S1 side which is the extending direction side of the diagonal seismic wall 12 (refer to the white arrow), the line of sight from the first building part b1 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy inside the living room 2 can be ensured.

[0027] Also, on the other side in the short side direction of the second building part b2 (the right side in the figure, X2 side), since the fifth building part b5 and the third building part b3 are adjacent at an intersection angle α (α3: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends obliquely 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, and 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. Therefore, on the other side in the short side direction of this second building part b2, while securing a view to the outdoor space S3 side which is the extending direction side of the diagonal seismic wall 12 (refer to the white arrow), the line of sight from the fifth building part b5 and the third building part b3 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy inside the living room 2 can be ensured.

[0028] On one side in the short side direction (the upper side in the figure, Y1 side) of the third building part b3 with the X direction as the longitudinal direction, since the fifth building part b5 and the second building part b2 are adjacent to each other at an intersection angle α (α3: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends obliquely 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, and is arranged on the outdoor space S3 side surrounded by the third building part b3, the fifth building part b5, and the second building part b2. Therefore, on one side in the short side direction of this third building part b3, while ensuring a view (refer to the white arrow) to the outdoor space S3 side which is the extending direction side of the diagonal seismic wall 12, the line of sight from the fifth building part b5 and the second building part b2 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy in the living room 2 can be ensured.

[0029] Also, on the other side in the short side direction (the lower side in the figure, Y2 side) of the third building part b3, since the fourth building part b4 is adjacent to each other at an intersection angle α (α4: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends obliquely 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, and is arranged on the outdoor space S4 side surrounded by the third building part b3 and the fourth building part b4. Therefore, on the other side in the short side direction of this third building part b3, while ensuring a view (refer to the white arrow) to the outdoor space S4 side which is the extending direction side of the diagonal seismic wall 12, the line of sight from the fourth building part b4 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy in the living room 2 can be ensured.

[0030] On one side in the short side direction of the fourth building part b4 with the Y direction as the longitudinal direction (the left side in the figure, the X1 side), since the fifth building part b5 and the first building part b1 are adjacent in a state where the intersection angle α (α2: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends at an angle of 45 degrees obliquely on the X1 side and the Y2 side (lower left in the figure) as an intermediate angle between the intersection angles α, and is arranged on the outdoor space S2 side surrounded by the fourth building part b4, the fifth building part b5, and the first building part b1. Therefore, on one side in the short side direction of this fourth building part b4, while ensuring the view to the outdoor space S2 side which is the extending direction side of the diagonal seismic wall 12 (refer to the white arrow), the line of sight from the fifth building part b5 and the first building part b1 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy in the living room 2 can be ensured.

[0031] Also, on the other side in the short side direction of the fourth building part b4 (the right side in the figure, the X2 side), since the third building part b3 is adjacent in a state where the intersection angle α (α4: 90 degrees in the illustrated example), the diagonal seismic wall 12 extends at an angle of 45 degrees obliquely on the X2 side and the Y2 side (lower right in the figure) as an intermediate angle between the intersection angles α, and is arranged on the outdoor space S4 side surrounded by the fourth building part b4 and the third building part b3. Therefore, on the other side in the short side direction of this fourth building part b4, while ensuring the view to the outdoor space S4 side which is the extending direction side of the diagonal seismic wall 12 (refer to the white arrow), the line of sight from the third building part b3 can be blocked by the wall surface of the diagonal seismic wall 12, and good privacy in the living room 2 can be ensured.

[0032] Similarly, on the X1 side (the left side in the figure) and the Y2 side (the lower side in the figure) of the fifth building part b5, it extends at an angle of 45 degrees obliquely on 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 parts (the first building part b1 and the fourth building part b4), and is arranged on the outdoor space S2 side surrounded by the fifth building part b5, the first building part b1, and the fourth building part b4. Therefore, on the X1 side and the Y2 side of this fifth building part b5, while ensuring the view to the outdoor space S2 side which is the extending direction side of the diagonal seismic wall 12 (refer to the white arrow), the line of sight from the adjacent building parts (the first building part b1 and the fourth building part b4) can be blocked by the wall surface of the diagonal seismic wall 12.

[0033] Also, on the X2 side (right side in the figure) and Y1 side (upper side in the figure) of the fifth building part b5, as an intermediate angle with respect to the intersection angle α (α3: 90 degrees in the illustrated example) with the adjacent building parts (the second building part b2 and the third building part b3), it is arranged on the outdoor space S3 side surrounded by the fifth building part b5, the second building part b2, and the third building part b3 in an oblique posture extending at an angle of 45 degrees obliquely to the upper right in the figure on the X2 side and Y1 side. Therefore, on the X2 side and Y1 side of this fifth building part b5, while securing a view to the outdoor space S3 side, which is the side in the extending direction of the diagonal seismic wall 12 (refer to the white arrow), the line of sight from the adjacent building parts (the second building part b2 and the third building part b3) can be blocked by the wall surface of the diagonal seismic wall 12.

[0034] Next, an explanation will be added regarding the arrangement of the diagonal seismic wall 12 in each residential building part Ba. As shown in FIG. 2, the diagonal seismic wall 12 is arranged at a predetermined pitch in the extending direction of the outdoor side surface 22 at the outer part of the outdoor side surface 22 of the living room 2 in each residential building part Ba. The arrangement pitch of the diagonal seismic wall 12 can be set, for example, so as to block the line of sight from all parts of the adjacent building part.

[0035] In the present embodiment, two (an example of a plurality) of diagonal seismic walls 12 are arranged corresponding to one living room 2. Among the two diagonal seismic walls 12 for each living room 2, one diagonal seismic wall 12A is arranged in a state of extending outward (toward the outdoor space) from the end in the extending direction of the outdoor side surface 22 of the living room 2 where the non-diagonal seismic wall 11 is arranged at the door boundary wall part 21. Among the two diagonal seismic walls 12 for each living room 2, the other diagonal seismic wall 12B is arranged in a state of extending outward from the middle part in the extending direction of the outdoor side surface 22 of the living room 2.

[0036] And the air supply part 23 that supplies air to the living room 2 and the exhaust part 24 that exhausts air from the living room 2 are arranged separately on one end side and the other end side in the extending direction of the outdoor side surface 22 of the living room 2 with the connection part of the diagonal seismic wall 12B on the outdoor side surface 22 of the living room 2 as a boundary. Note that the air supply part 23 and the exhaust part 24 can be configured, for example, by providing openings, fans, etc. on the outdoor side surface 22.

[0037] Therefore, in the outer part of the outdoor side surface 22 of the living room 2, the intake space for the air supply part 23 and the exhaust space by the exhaust part 24 can be partitioned by the diagonal seismic wall 12B, suppressing the short circuit between the air supply part 23 and the exhaust part 24 and enabling good ventilation of the living room 2 by the air supply part 23 and the exhaust part 24.

[0038] Moreover, in this embodiment, between the living rooms 2 adjacent in the extending direction of the outdoor side surface 22, the air supply part 23 of one living room 2 and the exhaust part 24 of the other are not adjacent to each other, but the exhaust parts 24 of both adjacent living rooms 2 are adjacent to each other. Therefore, a short circuit between the air supply part 23 of one living room 2 and the exhaust part 24 of the other living room 2 can also be suppressed. Instead of this, the air supply parts 23 of both adjacent living rooms 2 may be configured to be adjacent to each other.

[0039] 〔Alternative Embodiment〕 Another embodiment of the present invention will be described. Note that the configurations of the embodiments described below are not limited to being applied alone, and can also be applied in combination with the configurations of other embodiments.

[0040] (1) In the above-described embodiment, the case where the present invention is adopted for the building B having a wall-type structure with the slab and the seismic wall (wall column) 1 as the main body is shown as an example. However, the present invention may also be adopted for a building such as a ramen structure in which columns and beams are the main body and slabs and seismic walls are arranged.

[0041] (2) In the above-described embodiment, the case where the shielding target of the diagonal seismic wall 12 is the line of sight from the adjacent building part and the diagonal seismic wall 12 is set in a posture facing the wall surface with respect to the adjacent building part is shown as an example. However, for example, the shielding target of the diagonal seismic wall 12 may be the western sun, and the diagonal seismic wall 12 may be set in a posture facing the wall surface with respect to the western sun. The shielding target of the diagonal seismic wall 12 can be set according to the building use, the surrounding environment, etc.
