Description

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.

A tower-type apartment building with a rigid-frame structure and balconies that jut out from the exterior walls of the dwelling units located on the perimeter is widely known as a conventional building. In such conventional buildings, an in-frame construction method is used in which the outer perimeter framework (columns and beams) is installed on the exterior walls of the dwelling units (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 used in which the outer perimeter framework is placed on the outermost perimeter of the building (the outer edge of the balcony) and the beams are inverted (see, for example, Patent Document 2).

Japanese Patent Application Publication No. 6-129124 JP 2003-314081 A

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

The present invention was made with the above in mind, and its purpose is to provide a building that allows greater freedom in the room plans on the periphery, while minimizing the constraints imposed by the structure on the exterior, making it easy to improve the appearance.

In order to achieve the above-mentioned objective, the building of the present invention has outer perimeter columns and beams 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 perimeter, 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 thereto, an evacuation partition is installed on the balcony , and the columns are located on the balcony at a position equidistant from the outer wall of the dwelling unit and the outer edge of the balcony (Claim 1 ).

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 as not to be visible from the outside ( Claim 2 ).
In addition, the building of the present invention may be configured so that 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).

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

In other words, in a building with a balcony that projects outward from the exterior walls of rooms (e.g., dwelling units) on the periphery of the building, in an in-frame construction method in which an outer periphery frame is installed on the exterior walls of rooms, the outer periphery frame comes into contact with the exterior walls or appears inside the rooms, restricting the room plan, but in the buildings of the inventions according to the claims of this application, the outer periphery frame does not come into contact with the exterior walls or appear inside the rooms, 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 this 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.

Furthermore, in the building of the present invention, the intake and exhaust vents, downspouts, etc. can be placed in the space on the room side of the outer frame (or in the outer wall of the room) and hidden from view from the outside, resulting in a neat and tidy appearance.

In the building of the invention described in claim 1, by making the outer perimeter 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 the escape route on the balcony.

1 is an explanatory diagram of a building according to an embodiment of the present invention. 1A and 1B are a vertical cross-sectional view and a plan view of a main part of the building. 1A and 1B are a vertical 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. 1A and 1B 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.

The following describes an embodiment of the present invention.

Figure 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 vertically (across multiple floors), and outrigger earthquake-resistant walls 2 and 3 located at the top and middle parts (in Figure 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.

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. Inside the core wall 1, common areas such as an elevator hall and stairwell are provided, and outside the core wall 1 (i.e., the outer perimeter of the building), multiple dwelling units 4 (see Figures 2 (A) and (B)) are provided.

The outrigger earthquake-resistant walls 2, 3 are intended to prevent the building from rising up, and are rigidly attached to the core wall 1, for example, and are also connected to the outer perimeter framework of the building. In this example, the outrigger earthquake-resistant walls 2, 3 are arranged to form a roughly "I" shape with the core wall 1 in a plan view. 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.

In this example, as shown in Figures 2(A) and (B), the outer periphery columns 5 and beams 6 are positioned in the middle 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 positioned in the balcony 8 away from both the outer wall 7 and the outer edge of the balcony 8 (in the illustrated example, they are positioned approximately equidistant from the outer wall 7 and the outer edge of the balcony 8, but they may be positioned closer to the inside or the outside), and the top of the beams 6 is positioned midway up the water gradient of the balcony 8 floor. It is preferable that the size, position, and reinforcement of the columns 5 and beams 6 are designed 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.

Here, in a building with a balcony 8 that extends outward from the exterior wall 7 of the dwelling unit 4 on the periphery of the building, as shown in Figures 3(A) and (B), in an in-frame construction method in which the outer periphery frame is installed on the dwelling unit exterior wall 7, the outer periphery frame touches 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 touch 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 Figures 4(A) and (B), 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 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.

Furthermore, in this example building, the exhaust vents and downspouts are placed in the space on the dwelling unit 4 side of the outer frame (columns 5 and beams 6) (or in the dwelling unit exterior wall 7) and are not visible from the outside, resulting in a neat and tidy exterior.

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. In this way, by making the outer peripheral pillars 5 located in the middle of the balcony 8 in the inward and outward directions thinner, it becomes easier to ensure a sufficient width for the evacuation passage on the balcony 8.

The present invention is not limited to the above embodiment, and can be modified in various ways without departing from the spirit of the present invention. For example, the following modifications can be mentioned:

The present invention is not limited to the building in this example, but can be widely applied to buildings that have dwelling units 4 and living spaces with balconies 8 attached to the perimeter. That is, the building in this example has the advantage of being able to minimize the number of columns, beams, and earthquake-resistant walls and members that are constraints on the dwelling plan by resisting earthquake forces with the core wall 1 and the outrigger earthquake-resistant walls 2, 3 provided at the top and middle, but the present invention is not limited to this, and can be applied to, for example, buildings with multiple floors that do not have a core wall 1 or outrigger earthquake-resistant walls 2, 3. In addition, although the building in this example has a roughly square planar shape, it may have other planar shapes.

Here, examples of rooms include living rooms, dining rooms, bedrooms, and studies in residential buildings, classrooms and staff rooms in educational facilities, administrative offices, conference rooms, executive offices, and guard rooms in offices, sales floors, offices, and break rooms in retail stores, seating areas in restaurants, patient rooms, examination rooms, and nurse stations in hospitals, guest rooms and lobbies in hotels, work rooms in factories, and laboratories in research institutes.

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 plan view is smaller than the thickness in the direction perpendicular to the inward and outward directions, but this is not limited to the above, and some or all of the columns 8 may have a thickness in the inward and outward directions that is greater than the thickness in the direction perpendicular to the inward and outward directions, or the two thicknesses may be equal.

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

It goes without saying that the variations described in this specification may be combined as appropriate.
