  The preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the same reference numerals are used for the same elements in the drawings, and description thereof may be omitted as appropriate.

  FIG. 1 is a plan view of a reference floor of a building 1 which is an embodiment to which a corner portion of a building according to the present invention is applied. The building 1 is a cylindrical high-rise apartment building in which a plurality of layers are provided with an atrium 2 in the center, and the planar shape of the reference floor is substantially rectangular.

  The central part of the building 1 is provided with an atrium 2 that penetrates the floor in the vertical direction. , 15 are arranged. The dwelling unit 5 is a dwelling unit located at the corner of the building, and the dwelling unit 15 is a dwelling unit located at the side of the building. Reference numeral 4 denotes a core portion formed by an elevator, a staircase, or the like. The common corridor 3 faces the rectangular blow-off 2 and is bent at a right angle at a bending corner portion (a point where the traveling direction changes) 3a and is formed in a square shape in plan view. The building 1 is composed of a frame structure having earthquake resistance, but the structure type is not limited at all. There are four corner portions of the building 1, and the present invention is applied to each corner portion.

The floor part in the corner part of the building 1 is demonstrated with reference to FIG.
A corner cut portion 11 is provided at a corner portion (corner portion) of the building 1. That is, in the corner portion of the building 1, the floor portion 10 in which the internal space of the dwelling unit is formed is cut out by the corner cutting portion 11. The corner cutting part 11 cuts the inside of the intersection (CP) where the virtual extension planes of a pair of adjacent outer wall surfaces 6a, 6a in the corner part of the building 1 intersect among the outer wall surfaces 6 that define the outer periphery of the floor part 10. It is formed in a lacking manner. In this example, the corner cut portion 11 is linearly cut at an angle of 45 ° with respect to the outer wall surfaces 6a, 6a that are orthogonal to each other. The outer wall surface 6 is usually formed as a frame surface of the housing, and a floor portion for forming an internal space of the dwelling unit is formed inside thereof. The balcony is usually disposed outside the outer wall surface 6, but may be partially disposed inside the outer wall surface 6 (not shown).

A pair of extended floor portions 20 are provided to project outward from the outer wall surfaces 6a, 6a from both end portions 11a of the corner cut portion 11. On the extended floor 20, an interior space of a dwelling unit having a height from the floor to the ceiling is formed. The front surface side of the extended floor portion 20 is defined by a front surface portion 21 that is continuous with the corner cutting portion 11. Further, the extended floor portion 20 is defined by a front face portion 21 that is linearly continuous with the corner cut portion 11 in plan view.
The extended floor portion 20 is defined by a front surface portion 21 and a side surface portion 22 that extends from the outer end portion 21a of the front surface portion 21 substantially orthogonally to the outer wall surface 6a. For this reason, the extended floor part 20 has comprised the right angle isosceles triangle shape in planar view. A window is provided in the corner cutting part 11 and the front part 21 and the side part 22 of the extended floor part 20 so that a view can be obtained.
When the length of the corner cut portion 11 is L0, the length of the front surface portion 21 of the extended floor portion 20 is L3, and the length of the side surface portion 22 of the extended floor portion 20 is L2, the length L0 of the corner cut portion 11 is set. And a length (L1) obtained by multiplying the sum of the length L3 of the front surface portion 21 of the pair of extended floor portions 20 by 1/2 is formed to be larger than the length L2 of the side surface portion 22. That is, L1 = (L0 + L3 × 2) × 1/2, and L1> L2. The length of L1 is a length that can form one side of one room, and is usually 2.7 m or more, preferably 5.4 m or more.
Moreover, the linear door boundary wall 30 substantially orthogonal to the corner cutting part 11 is provided, the corner part of a building is divided | segmented, and the two dwelling units 5 and 5 are arrange | positioned. The boundary wall 30 connects the substantially central part of the corner cutting part 11 and the corner part 3a of the common corridor 3, and as shown in FIG. If the portion is a reference axis direction, it is formed so as to be along an axis swung by 45 °.

Such a characteristic configuration will be described based on FIG. 3 in comparison with the one described in Patent Document 1 (FIG. 5C) as a comparative example. FIG. 3A is a plan view of a corner portion of the building 1 of Example 1, and FIG. 3B is a plan view of the one described in Patent Document 1 as a comparative example.
In the first embodiment, the extended floor portion 20 is defined by a front surface portion 21 that is linearly continuous with the corner cut portion 11 in plan view, and the expanded floor portion 20 includes the front surface portion 21 and the outer end portion of the front surface portion. Since it is defined by the side surface portion 22 extending substantially orthogonally from 21a to the outer wall surface 6a, a wide view and abundant daylight with the view direction orthogonal to the corner cut portion 11 are obtained. And the door boundary wall 30 substantially orthogonal to the corner cut part 11 can be provided in the corner part of the building 1, and two dwelling units can be arrange | positioned in a corner part. The dwelling units 5 and 5 do not match each other, and can perform two-sided lighting (the direction in which the corner cut portion 11 faces and the direction in which the side surface portion 22 faces).

  Further, the length (L1) obtained by multiplying the sum of the length L0 of the corner cut portion 11 and the length L3 of the front surface portion 21 of the pair of extended floor portions 20 by 1/2 is greater than the length L2 of the side surface portion 22. Zone A (shaded hatched portion) formed into a square shape by the corner cut portion 11 and the extended floor portion 20 at the corner cut portion 11 (inner side) despite being a large dwelling unit. ) Is formed. This zone A is a horizontally long rectangular shape with a long corner cutting direction of the corner cutting portion 11 and has a wide view surface. Therefore, a room (such as a living room canteen) facing the wide view surface can be arranged. It is easy to deal with both the case where two dwelling units are arranged at the corner of the building and the case where one dwelling unit having a large exclusive area is arranged, and it is easy to plan layout and dwelling unit arrangement and has a high degree of freedom. . The fact that two dwelling units with excellent view environments are obtained at each corner greatly increases the commercial value of the building.

  On the other hand, in the comparative example, since the overhang portion (25) is formed further outside the intersection (CP), the overhang portion (25) greatly protrudes outside the floor portion with the outer wall surface 6a as a reference line. An increase in area is inevitable. The length m1 of the hypotenuse corresponding to L1 of the present invention is smaller than L1, and the length of the side portion 22 corresponding to the length L2 is the length of the hypotenuse (m1 + m2). It becomes larger than the length m1. When the building area is constant, the overhanging part (25) is a narrow and narrow space with a narrow frontage compared to the example, so that it can be constructed as a bay window, but as in Example 1. A wide view and abundant daylight cannot be obtained, and a corner wall is provided at the corner of the building as in Example 1 so as to be almost orthogonal to the corner cutout (in a manner in which the overhang (25) is divided). It is difficult to place two dwelling units in the department.

  FIG. 4 is a plan view of the reference floor of the building 1 (a collective housing) according to the second embodiment to which the corner portion of the building according to the present invention is applied. Unlike the first embodiment, the building 1 of the second embodiment is not cylindrical, and its planar shape is substantially C-shaped.

The building 1 of the third embodiment is different from the first embodiment in that it is not cylindrical, has no blow-by in the central portion, and is a so-called center core type building provided with a core portion 4 formed by an elevator, stairs, etc. in the central portion. It is.
There are four corner portions of the building, and the same configuration as in the first embodiment is applied to each corner portion. It is a building with a relatively small area, and the corner portion of the building of the present invention is applied to all the dwelling units on one floor. Since one floor is occupied by a corner dwelling unit with excellent living environment and high product value, the product value of the entire apartment can be significantly improved.

FIG. 6 is a plan view of the reference floor of the building 1 (collective housing) according to the fourth embodiment to which the corner portion of the building according to the present invention is applied. The building 1 of the fourth embodiment is basically the same in configuration as the first embodiment, but is a building having a larger building area, and also illustrates a configuration example of columns and balconies constituting the frame. There are four corner portions of the building, and the same configuration of the present invention as in the first embodiment is applied to each corner portion.
Inner pillars 7, 7,... Constituting the inner frame are arranged inside the shared hallway 3. The outer pillars 8, 8,... Constituting the outer frame are disposed outside the floor 10 that forms the internal space of the dwelling unit 5, and the outer wall surface 6 is formed along the outer pillars 8, 8,. . A balcony 9 is disposed outside the outer wall surface 6, and a balcony 9 a is disposed outside the corner cut portion 11 at the corner portion of the building.
