Description

Technical Field

[0001] The present invention relates to a building having a number of floors, such as an office building or a commercial building.

Background Art

[0002] Buildings such as office buildings and commercial buildings are generally in the form of multi-story buildings having a number of floors.

[0003] Such a building having a number of floors is subject to the oblique line limit or sky rate limit under the Building Standards Law when it exceeds a predetermined height depending on the usage area.

[0004] Conventionally, as a building having a number of floors, in order to clear the oblique line limit or sky rate limit under the Building Standards Law, there is known a structure in which the upper floor part is set back stepwise with respect to the lower floor part with respect to the road (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, when the structure is such that the upper floor part is set back stepwise with respect to the lower floor part as in the above conventional building, there is a problem that the floor area of the upper floor becomes narrower by the amount of the setback, and it becomes difficult to secure the floor area of the entire building.

[0007] The present invention has been made in view of such problems, and an object thereof is to provide a building that can easily secure a floor area while clearing the oblique line limit or sky rate limit.

Means for Solving the Problems

[0008] The present invention relates to a building having multiple floors, wherein the exterior wall is inclined upward, and the front An inner wall provided on the inside of the outer wall and arranged parallel to the outer wall, and a window provided adjacent to the outer wall and the inner wall and arranged parallel to the outer wall and the inner wall, A column provided on the interior side of the interior wall and arranged parallel to the interior wall, It is characterized by having the following features. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a building that can easily secure floor area while clearing restrictions on setback lines or sky ratio. [Brief explanation of the drawing]

[0011] [Figure 1] This is a front view of a building relating to one embodiment of the present invention. [Figure 2] Figure 1 is a side view of the building shown. [Figure 3] This is an enlarged view of area A of the building shown in Figure 1. [Figure 4] This is a cross-sectional view of the upper floors of the building shown in Figure 1. [Figure 5] This is a schematic cross-sectional view of the comparative example building. [Modes for carrying out the invention]

[0012] The following describes in detail an example of a building according to one embodiment of the present invention, with reference to the drawings.

[0013] As shown in Figures 1 and 2, the building 1 according to this embodiment is a multi-story building that can be used, for example, as an office building or a commercial building.

[0014] In the lower floors of Building 1, from the first floor (ground floor) to the third floor, the exterior wall 2a on the front (the side shown in Figure 1), the exterior wall 2b on the side (the side shown in Figure 2), and the exterior wall 2c at the corner between the front and side are all perpendicular to the ground 3. These exterior walls 2a on the front, 2b on the side, and 2c at the corner are walls facing the road.

[0015] In contrast, the front exterior wall 4a, side exterior wall 4b, and corner exterior wall 4c of the upper floors of Building 1, above the fourth floor, are inclined upward at a predetermined fixed angle with respect to the direction perpendicular to the ground 3 (vertical direction) in order to comply with the setback regulations or sky ratio regulations under the Building Standards Act.

[0016] As shown in Figure 1, the front exterior wall 4a of the upper floors of the building 1, above the fourth floor, is provided with window sections 5 and exterior wall panels 6 that extend inclined in the vertical direction. More specifically, in this embodiment, multiple striped window sections 5 and exterior wall panels 6 are arranged alternately in a horizontal line on the exterior wall 4a, each extending inclined from the lower end to the upper end of the exterior wall 4a. Note that the building 1 can also be configured without exterior wall panels 6, for example, by providing window sections 5 across the entire exterior wall 4a without any exterior wall panels 6.

[0017] As shown in Figure 3, each window section 5 has a configuration in which two vertically elongated, parallelogram-shaped, plate-like windows 5a are arranged vertically on each floor. However, the window section 5 may also have a configuration in which one vertically elongated, parallelogram-shaped window 5a is arranged on each floor, or a configuration in which three or more vertically elongated, parallelogram-shaped windows 5a are arranged vertically on each floor, or a configuration in which one vertically elongated, parallelogram-shaped window 5a is arranged across multiple floors.

[0018] Each outer wall panel 6 has a configuration in which a plurality of vertically long parallelogram panel units 6a are arranged vertically side by side through slits 7. Each panel unit 6a has a vertical length corresponding to each layer and is arranged adjacent to the two windows 5a of each layer. Note that the panel unit 6a may have a vertical length spanning a plurality of layers, or the entire outer wall panel 6 may be composed of a single panel unit 6a.

[0019] As shown in FIG. 4, the building 1 has an inner wall 8 provided inside the outer wall 4a. The inner wall 8 is inclined at the same angle as the outer wall 4a and is arranged parallel to the outer wall 4a.

[0020] The building 1 has columns 9 that form its structure on the indoor side with respect to the inner wall 8. The columns 9 are formed of concrete-filled steel pipes and, as shown in FIG. 3, inside the outer wall panel 6, they are inclined at the same angle in the same direction as the window portion 5 with respect to the vertical direction and extend along the window portion 5 or window 5a. Note that the columns 9 may have other configurations such as reinforced concrete.

[0021] In this embodiment, the building 1 is configured such that the window portion 5 to window 5a extends obliquely in the left-right direction in FIG. 1 with respect to the vertical direction, but the window portion 5 to window 5a may extend without being inclined in the left-right direction in FIG. 1 along the vertical direction.

[0022] As shown in FIG. 4, on each floor of the upper layer where the outer wall 4a and the inner wall 8 of the building 1 are inclined, the windows 5a provided adjacent to the outer wall 4a and the inner wall 8 are each arranged parallel to the outer wall 4a and the inner wall 8. That is, when viewed from the outside of the building 1, the windows 5a are inclined upward in the same manner as the outer wall 4a.

[0023] Thus, in the building 1 of this embodiment, the slope restrictions or sky ratio restrictions under the Building Standards Act can be cleared by sloping the exterior wall 4a of the upper floors upward. Furthermore, in the building 1 of this embodiment, the interior wall 8 and windows 5a are arranged parallel to the exterior wall 4a, so on each floor, the lower end of the windows 5a is positioned further outward from the building 1 than the upper end. As a result, compared to the comparative example building 20 shown in Figure 5, where the exterior wall 4a and interior wall 8 and windows 5a are arranged vertically and each floor is set back in a stepped manner, the floor 12 of each floor can be configured to project further outward from the ceiling 11, thereby increasing the floor area of ​​each floor.

[0024] As shown in Figure 4, in the building 1 of this embodiment, the column 9 is provided on the interior side relative to the interior wall 8, and is positioned parallel to the interior wall 8, inclined at the same angle as the exterior wall 4a and the interior wall 8.

[0025] If the column 9 is configured to extend vertically inside the interior wall 8, a triangular or trapezoidal dead space will be created between the column 9 and the interior wall 8, thereby reducing the effective floor area. In contrast, in the building 1 of this embodiment, the column 9 is configured to be arranged parallel to the interior wall 8, so that the dead space is not created and the effective floor area can be increased.

[0026] The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from its spirit.

[0027] For example, in this embodiment, all floors above the fourth floor of building 1 are considered upper floors, and the exterior walls 4a, 4b, and 4c of these upper floors are inclined upwards. However, as long as the requirements of the Building Standards Act regarding setbacks or sky ratio can be met, the upper floors may be defined as any floor above a desired floor other than the fourth floor, and the exterior walls 4a, 4b, and 4c of these upper floors may be inclined upwards. Alternatively, only the exterior walls 4a of several intermediate floors between the desired floor and the top floor may be inclined upwards.

[0028] Furthermore, in this embodiment, all exterior walls 4a, 4b, and 4c on the front, sides, and corners of the building 1 are constructed with an upward inclination. However, it is sufficient to construct only the exterior walls that are subject to the setback regulations or sky ratio regulations under the Building Standards Act with an upward inclination.
