Description

[Technical field]

[0001] The present invention relates to buildings suitable for use as, for example, apartment buildings, educational facilities, office buildings, commercial facilities, leisure facilities, medical and welfare facilities, and accommodation facilities. [Background technology]

[0002] A tower-type apartment building that adopts a rigid-frame structure and has balconies that extend outward from the outer walls of the dwelling units arranged on the periphery is widely known as a conventional building. In such conventional buildings, an in-frame construction method is adopted in which the outer frame (columns and beams) is installed on the outer wall of the dwelling unit (the boundary between the interior of the dwelling unit and the balcony) (see, for example, Patent Document 1), or an out-frame construction method is adopted in which the outer frame is arranged on the outermost periphery of the building (the outer edge of the balcony) and the beams are inverted (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-129124 [Patent Document 2] JP 2003-314081 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the former (in-frame construction), the outer perimeter columns and beams appear inside the dwelling, restricting the dwelling (room) plan, while in the latter (out-frame construction), the outer perimeter framework that appears on the building's outer perimeter restricts the exterior appearance.

[0005] The present invention has been made with the above-mentioned considerations in mind, and its purpose is to provide a building which increases the freedom of room plans to be set up on the outer periphery, while minimizing the constraints imposed by the structure in terms of the exterior, making it easy to improve the appearance. [Means for solving the problem]

[0006] In order to achieve the above object, the building according to the present invention is characterized in that the outer periphery columns and beams are located at the middle of the inside and outside direction of the balcony that protrudes outward from the outer wall of the dwelling unit at the outer periphery, the thickness of the columns in the inside and outside direction of the balcony is smaller than the thickness in the direction perpendicular thereto in a plan view, and an evacuation partition is installed on the balcony. The pillar is located on the balcony at an equal distance from the exterior wall of the dwelling unit and the outer edge of the balcony. (Claim 1 )。

[0007] In the above-mentioned building, an intake / exhaust vent or a downspout may be placed in the space on the dwelling unit side of the outer perimeter columns and beams so that it cannot be seen from the outside (claim Section 2 ). In addition, in the building of the present invention, the outer peripheral columns and beams are located in the middle in the inward / outward direction of a balcony that protrudes outward from the outer wall of the dwelling unit on the outer periphery, and in a plan view, the thickness of the columns in the inward / outward direction of the balcony is smaller than the thickness in a direction perpendicular to this, an evacuation partition is installed on the balcony, and intake and exhaust vents or downspouts are placed in the space on the dwelling unit side of the outer peripheral columns and beams so as not to be visible from the outside (Claim 3). Effect of the Invention

[0008] The present invention provides a building that allows greater freedom in room plans on the outer periphery, while reducing the constraints imposed by the structure in terms of the exterior appearance, making it easy to improve the appearance.

[0009] That is, in a building with a balcony that projects outward from the exterior wall of a room (e.g., a dwelling unit) on the periphery of the building, in an in-frame construction method in which an outer periphery frame is installed on the exterior wall of the room, the outer periphery frame comes into contact with the exterior wall or appears inside the room, restricting the room plan, but in the building of the invention according to each claim of this application, the outer periphery frame does not come into contact with the exterior wall or appear inside the room, so the room plan is not restricted and the degree of freedom can be increased. Also, in an out-frame construction method in which the outer periphery frame is placed on the outermost periphery of the building (the outer edge of the balcony), the outer periphery frame that appears on the outer periphery of the building restricts the appearance, but in the building of the present invention, the outer periphery frame does not appear on the outer periphery of the building, so the appearance is not restricted and the degree of freedom can be increased.

[0010] Furthermore, in the building of the present invention, intake and exhaust vents, downspouts, etc. can be placed in the space on the occupant side of the outer peripheral frame (or in the outer wall of the occupant room) so that they are not visible from the outside, thereby achieving a neat appearance.

[0011] In the building of the invention as claimed in claim 1, by making the outer peripheral columns located in the middle of the balcony in the inward and outward directions thinner in the inward and outward directions, it becomes easy to ensure a sufficient width for an evacuation passage on the balcony. [Brief description of the drawings]

[Diagram 3] 13(A) and (B) are a longitudinal cross-sectional view and a plan view of a main part of a building that employs an in-frame construction method according to a comparative example. [Figure 4] 13(A) and (B) are a longitudinal cross-sectional view and a plan view of the main parts of a building that employs an out-frame construction method relating to a comparative example. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An embodiment of the present invention will be described below.

[0014] FIG. 1 is an explanatory diagram (perspective view) conceptually showing the overall structure of the building of this example. As shown in this figure, the building of this example is equipped with a core wall (multiple-story earthquake-resistant wall) 1 that is provided in the core part and continues in the vertical direction (across multiple floors), and outrigger earthquake-resistant walls 2 and 3 located at the top and middle parts (in FIG. 1, the outer shape of the building is shown by a dashed line to easily show the core wall 1 and the outrigger earthquake-resistant walls 2 and 3). The building of this example is constructed as a super-high-rise apartment building with a rigid frame structure, and its planar shape is a tower shape that is approximately square. The columns and beams that make up the rigid frame structure can be made of reinforced concrete or steel.

[0015] The core wall 1, which is roughly square in plan view, bears most of the seismic force and is constructed as a highly rigid earthquake-resistant wall. Common areas such as an elevator hall and stairwell are provided inside the core wall 1, and multiple dwelling units 4 (see Figures 2(A) and (B)) are provided outside the core wall 1 (i.e., on the perimeter of the building).

[0016] The outrigger earthquake-resistant walls 2, 3 are intended to prevent the building from rising up, and are rigidly connected, for example, to the core wall 1 and to the framework around the building periphery. In this example, the outrigger earthquake-resistant walls 2, 3 are provided so as to form a roughly "I" shape in plan view with the core wall 1. Also, in this example, the outrigger earthquake-resistant wall 3 in the middle is made thicker in both the vertical direction than the outrigger earthquake-resistant wall 2 at the top.

[0017] In this example, as shown in Figures 2(A) and (B), the outer periphery columns 5 and beams 6 are located in the middle in the inward and outward direction of the balcony 8 that protrudes outward from the outer wall 7 of the dwelling unit 4 on the outer periphery. That is, the columns 5 are located in a position on the balcony 8 that is separated from both the outer wall 7 and the outer edge of the balcony 8 (in the illustrated example, the columns 5 are located at a position approximately equidistant from the outer wall 7 and the outer edge of the balcony 8, but they may be located closer to the inside or the outside), and the top end of the beams 6 is located halfway up the water gradient of the floor of the balcony 8. It is preferable that the size, position, and arrangement of reinforcement of the columns 5 and beams 6 are carefully considered so that they do not become a visual restriction from the opening of the dwelling unit 4 and do not interfere with the installation of an evacuation bulkhead on the balcony 8.

[0018] Here, in a building with a balcony 8 extending outward from the exterior wall 7 of the dwelling unit 4 on the periphery of the building, as shown in Figs. 3(A) and (B), in an in-frame construction method in which an outer periphery frame is installed on the dwelling unit exterior wall 7, the outer periphery frame comes into contact with the exterior wall 7 or appears inside the dwelling unit 4, restricting the dwelling unit plan, but in the building of this example, the outer periphery frame does not come into contact with the exterior wall 7 or appear inside the dwelling unit 4, so the dwelling unit plan is not restricted and the degree of freedom can be increased. Also, as shown in Figs. 4(A) and (B), in an out-frame construction method in which the outer periphery frame is arranged on the outermost periphery of the building (the outer edge of the balcony 8), the outer periphery frame (columns 5 and beams 6) that appears on the outer periphery of the building restricts the appearance, but in the building of this example, the outer periphery frame (columns 5 and beams 6) does not appear on the outer periphery of the building, so the appearance is not restricted and the degree of freedom can be increased.

[0019] Furthermore, in the building of this example, the intake and exhaust vents, downspouts, etc. are placed in the space on the dwelling unit 4 side of the outer peripheral structure (columns 5 and beams 6) (or in the dwelling unit exterior wall 7) so that they are not visible from the outside, achieving a neat and tidy exterior.

[0020] In addition, in the building of this example, as shown in Figure 2 (B), in plan view, the pillars 8 located in the middle of the balcony 8 in the inward and outward directions are flattened so that their thickness in the inward and outward directions is smaller than their thickness in the direction perpendicular to the inward and outward directions. By making the outer perimeter pillars 5 located in the middle of the balcony 8 in the inward and outward directions thinner in this way, it becomes easy to ensure a sufficient width for an evacuation passage in the balcony 8.

[0021] It is to be noted that the present invention is not limited to the above-described embodiment, and can be modified in various ways without departing from the spirit and scope of the present invention. For example, the following modifications can be mentioned.

[0022] The present invention is not limited to the building of this example, but can be widely applied to buildings that have dwelling units 4 and living rooms with balconies 8 attached to the periphery. That is, the building of this example has an advantage that the number and members of columns, beams, and earthquake-resistant walls that are constraints on the dwelling unit plan can be minimized by resisting earthquake forces with the core wall 1 and the outrigger earthquake-resistant walls 2, 3 provided at the top and middle parts, but the present invention is not limited to this, and can be applied to, for example, buildings with multiple floors that do not have the core wall 1 or the outrigger earthquake-resistant walls 2, 3. In addition, the building of this example has a substantially square planar shape, but the planar shape may be another shape.

[0023] Here, examples of habitable rooms include living rooms, dining rooms, bedrooms and studies in a residence, classrooms and staff rooms in an educational facility, administrative rooms, conference rooms, executive rooms and guard rooms in an office, sales floors, offices and break rooms in a retail store, seating areas in a restaurant, patient rooms, examination rooms and nurse stations in a hospital, guest rooms and lobbies in a hotel, work rooms in a factory, and laboratories in a research institute, etc.

[0024] In this example, all of the columns 8 located in the middle of the balcony 8 in the inward and outward directions are flat columns whose thickness in the inward and outward directions in a plan view is smaller than the thickness in the direction perpendicular to the inward and outward directions. However, this is not limited to the above, and some or all of the columns 8 may have a thickness in the inward and outward direction that is greater than the thickness in the direction perpendicular to the inward and outward directions, or the two thicknesses may be equal.

[0025] Furthermore, the present invention can be widely applied to buildings that have dwelling units 4 or rooms with eaves instead of balconies 8 on the outer periphery.

[0026] It goes without saying that the modified examples given in this specification may be combined as appropriate. [Explanation of symbols]
