Description

  The present invention relates to a triangular prism type building unit.

Conventionally, in some cases, an open space such as a piloti used as an entrance, a garage, a terrace, or the like is provided in a lower floor corner portion of a building such as a house. As a method of providing an open space such as a piloti in a building, for example, a system is adopted in which the inside of a frame of a box-shaped building unit is an open space such as a piloti (see Patent Document 1).
In other words, if you want to form a concave open space in the lower corner of the box-shaped building body, and omit the building unit for that part, you can directly connect the balcony, room, roof, etc. The upper part cannot be supported, affecting the strength of the entire building. However, as described above, if the inside of the frame of the building unit is used as an open space such as a piloti, it is possible to avoid disrupting the unit configuration arranged in a normal box shape and hardly affect the strength of the entire building. There is.

  In addition, four substantially rectangular parallelepiped building units are arranged in such a way that one column-omitted corner portion determined for each building unit is abutted to form a large space without columns across the four building units. A unit type building is known in which reinforcing beams are provided between adjacent building units to reinforce the entire building (see Patent Document 2).

Japanese Patent Laid-Open No. 08-128110 JP 2002-054236 A

By the way, when the inside of the building unit is used as an open space such as a piloti, the pillars constituting the building unit are visible, and there is a demand for omitting the pillars in consideration of the feeling of openness and landscape.
Therefore, it is conceivable to use a building unit having a column omitting corner as described in Patent Document 2. However, it is not easy to attach reinforcing beams along the outer periphery of the unit type building, and if the pillars are omitted, it will be difficult to support the upper part of the room or balcony located directly above. There was a problem.

  In addition, as described in Patent Document 2, in forming a large space without pillars inside a unit-type building, each building unit is brought into contact with each other by omitting the respective pillar omitted corners, The unit and the reinforcing beam must be connected. Furthermore, the reinforcing beam has a special shape that is different from other beam members constituting the building unit. For this reason, it may take time and cost to manufacture the reinforcing beam, and it may take time to construct the reinforcing beam on site.

  In view of the above points, there is a request to omit one pillar of the building unit, change the appearance of the unit type building, or expand the internal space of the unit type building, but omit the pillar In order to adopt the unit, the reinforcing beam must also be adopted as a set. However, when reinforcing beams are used as a set, it is difficult to easily adopt a building unit that omits pillars in terms of cost and labor.

  As described above, the oblique floor beams 23, the auxiliary floor beams 24 and 25, the oblique ceiling beams 33, and the auxiliary ceiling beams 34 and 35 are arranged to be shifted downward, so that floor materials and joists are placed in the building units 1E to 1H. It is effective when installing. This will be specifically described below.

  As shown in FIG. 11, when a plurality of joists 41,... Are attached to the building unit 1H, the following is performed. First, the building unit 1H is assembled. Specifically, both ends of the long-side floor beam 21 are rigidly connected to the lower ends of the columns 11 and 12, and both ends of the long-side ceiling beam 31 are rigidly connected to the upper ends of the columns 11 and 12. Both ends of the beam 22 are rigidly coupled to the lower ends of the columns 11 and 13, and both ends of the short side ceiling beam 32 are rigidly coupled to the upper ends of the columns 11 and 13. The hypotenuse floor beam 23 is disposed at a position lower than the floor beams 21 and 22, and both ends of the hypotenuse floor beam 23 are pin-coupled to the columns 12 and 13. The auxiliary floor beams 24 and 25 are disposed at positions lower than the floor beams 21 and 22, and both ends of the auxiliary floor beams 24 and 25 are joined to the beams 21 and 23. The auxiliary ceiling beams 34 and 35 are arranged at positions lower than the ceiling beams 31 and 32, and both ends of the auxiliary ceiling beams 34 and 35 are joined to the beams 31 and 33.

Here, since the oblique side ceiling beam 33 of the building unit 1F is provided at a position lower than the ceiling beams 31, 32, the oblique side floor beam 23 of the building unit 1H is provided at a position lower than the floor beams 21, 22. However, the oblique side ceiling beam 33 of the building unit 1F and the oblique side floor beam 23 of the building unit 1H do not interfere with each other.

  The combination of the building unit 1H and the building unit 1F to which the column 19, the floor beams 28 and 29 and the ceiling beams 38 and 39 are attached is used for a unit type building, and the building unit 1F constitutes a part of the first floor of the unit type building. The building unit 1H, the pillar 19, the floor beams 28 and 29, and the ceiling beams 38 and 39 constitute a part of the second floor. The second floor portion of the unit type building (particularly, the column 19, the floor beams 28 and 29 and the ceiling beams 38 and 39) protrudes outside the first floor portion (particularly the portion of the building unit 1F). This structure is called overhang. For example, the building unit 1F is used for a piloti on the first floor, and the building unit 1H is used on a piloti.

On the east side of the entrance porch 53, a carport entrance / exit 55 (that is, an open space) in a state where a column corresponding to the lower floor corner portion C2 of the unit type building 50 is removed is disposed. A car port 56 is disposed on the north side of the car port entrance 55.
In addition, the piloti 54 and the carport entrance 55 which are open spaces in a state where the pillars are removed are configured by the building units 1 and 1R. That is, the upper portions of normal rectangular parallelepiped building units 80, 80, etc. are installed on the building units 1, 1R.
Further, the entrance porch 53, the piloti 54, and the carport entrance 55 are recognized as a continuous piloty space in the front of the building.

There is an indoor space of the unit building 50 on the north side of the entrance porch 53 and the piloti 54 and on the west side of the carport 56. On the north side of the entrance porch 53 in the indoor space, an entrance 57 including an entrance soil and an entrance hall is disposed. The entrance 57 is provided with a stairs 57a for going back and forth between the first floor and the second floor.
From the north side to the west side of the entrance 57, a community pouch 58 formed in a substantially L shape in plan view is disposed. A plurality of windows are provided on the outer wall around the community pouch 58. By opening the windows, the community pouch 58 can be recognized as an open space opened outdoors.

A hole 59 located at the center of the second floor is disposed at the top of the stairs 57a. On the south side of the hall 59, a sanitary 60 having a bathroom, a washroom, and a toilet is disposed. Further, on the south side of the sanitary 60, a balcony 60a is disposed.
A kitchen 61 is disposed on the north side of the hall 59. Further, on the west side of the kitchen 61, the hall 59, the sanitary 60, and the balcony 60a, a room 62 in which functions of a living room and a dining room coexist is provided. Further, a balcony 62 a is arranged on the west side of the room 62.
A main bedroom 63 is arranged on the east side of the hall 59, the sanitary 60, the balcony 60a, and the kitchen 61. In addition, a balcony 63a is disposed on the east side of the main bedroom 63, and a north side portion of the main bedroom 63 is a slightly raised tatami space 63b.

Storage parts 62b and 62b for the room 62 are provided on the north side and the south side of the balcony 62a. These balconies 62a and storage portions 62b, 62b protrude outward from the west end of the first floor of the building body 52, and are overhanging.
Storage portions 63c, 63c, 63c for the main bedroom 63 are provided on the north side and the south side of the balcony 63a. These balconies 63a and storage parts 63c, 63c, and 63c protrude outward from the east end of the first floor of the building body 52, and are overhanging.

As the building unit constituting these overhang portions, a hanger unit 90 that is set smaller in size than the rectangular parallelepiped building unit 80 and connected to the adjacent rectangular parallelepiped building unit 80 is used. The hanger unit 90 is configured by a member having substantially the same shape as that of the rectangular parallelepiped building unit 80 although the overall size is smaller than that of the rectangular parallelepiped building unit 80.
In the unit type building 50, the rectangular parallelepiped building unit 80 is used except for the piloti 54, the carport entrance 55, and the hanger unit 90.

That is, the rectangular parallelepiped building unit 80 that constitutes the south end of the main bedroom 63 is provided as an upper portion of the building unit 1 that constitutes the carport entrance 55.
In the present embodiment, the rectangular parallelepiped building unit 80 (the rooms 62 and 63 provided therein) is taken as an example of the upper part, but the present invention is not limited to this and can be changed as appropriate. For example, a balcony unit or a roof for forming a balcony may be set directly above.

Since such a unit type building 50 is configured to include the building unit 1, in constructing the unit type building 50, for example, a column can be easily omitted without using a conventional reinforcing beam. it can.
In other words, since the building unit 1 is formed as a structure by itself, it can be applied to various places in the unit type building 50. As a result, for example, the appearance of the unit-type building 50 can be changed, or a large space can be formed inside the building without using a reinforcing beam, which is realized only with a normal rectangular parallelepiped building unit 80 formed in a substantially rectangular parallelepiped shape. It is possible to construct a unit building 50 having a configuration that is difficult to perform.
Moreover, since the normal rectangular parallelepiped building unit 80 is installed on the building unit 1, the normal rectangular parallelepiped building unit 80 can be installed so as to overhang the building unit 1, and the normal rectangular parallelepiped building unit 80 can be installed. An open space with no pillars can be formed below the mold building unit 80. As a result, it is possible to improve the feeling of openness and landscape at the lower corner portions C1, C2.
In addition, although the unit type building 50 of this Embodiment assumed that it was multi-story, it is not restricted to this, A unit type building of a one-story may be sufficient. In that case, the lower floor corner portions C1 and C2 indicate the corner portions on the first floor in a one-story unit type building. Further, as the directly upper part of the building unit 1, not the rectangular parallelepiped building unit 80 but another directly upper part such as a roof unit or a fence constituting the roof 64 is provided.

  The normal rectangular parallelepiped building unit 80 and the building unit 1 are arranged up and down, and the normal rectangular parallelepiped building unit 80 and the building unit 1R are arranged up and down. The rectangular parallelepiped building units 80, 80 can be overhanged.

  Since the rigidity of the building units 1, 1 </ b> R is high, it is possible to install the cuboid building unit 80 or the like directly above the building units 1, 1 </ b> R by overhanging them, and to support them reliably. Therefore, an open space with no pillars can be formed directly below the upper part, and it is possible to improve the sense of openness and landscape at the lower floor corner portions C1 and C2.

A modification of the unit type building 50 will be described.
FIG. 17 is a schematic plan view of a unit building 50 </ b> A obtained by changing a part of the unit building 50. As shown in FIG. 17, the building unit 1 is arranged in the corner part C3 of the first floor and the second floor of the unit type building 50A with the oblique sides facing outward, and the building unit 1 is along its own oblique side ceiling beam 33. Thus, the outer wall surface 42 is arranged. A balcony 67 is provided on the outer wall surface 42 of the building unit 1 on the second floor. That is, the balcony 17 is provided in a direction (90 degrees) orthogonal to the outer wall surface 42 in plan view.
In addition, although the balcony 17 is formed in the planar view rectangular shape in the example of illustration, other shapes may be sufficient.
If the balcony 17 is provided on the outer wall surface 42 of the building unit 1 on the second floor as described above, the balcony 17 that is disposed obliquely can be installed at the corner portion C3 of the unit type building 50A. Thereby, the external appearance of the unit type building 50A is different from the external appearance of the unit type building 50. That is, the external appearance of the unit type building 50A is difficult to be realized only by the rectangular parallelepiped type building unit 80, and the unit type building 50A having such an external appearance can be easily constructed.

FIG. 18 is a schematic plan view of a unit building 50B obtained by changing a part of the unit building 50. FIG.
More specifically, as the normal rectangular parallelepiped building unit 80 installed on the building unit 1, one having an outer wall surface 89 arranged along the oblique side ceiling beam 33 of the building unit 1 is used.
Then, the balcony 18 that is disposed outside the outer wall surface 89 at the corner of the rectangular parallelepiped building unit 80 at the corner portion C4 of the unit-type building 50 and has no support portion below and formed in a substantially right triangle shape in plan view. Try to provide it. That is, the rectangular parallelepiped building unit 80 having the balcony 18 can be reliably supported by the building unit 1 on the first floor.
Accordingly, the balcony 18 having a substantially right triangle shape in a plan view and having no support portion below can be installed in the corner portion C4 of the unit type building 50B. Thereby, the external appearance of the unit type building 50B is changed from the external appearance of the unit type building 50. That is, the external appearance of the unit type building 50B is difficult to realize with only the rectangular parallelepiped building unit 80, and the unit type building 50B having such an external appearance can be easily constructed. Moreover, the open space of the state which does not have a pillar under the balcony 18 can be formed.

[Specific example of unit type building constructed by unit method (2)]
Two or more building units 1 (in place of building unit 1, any of building units 1 </ b> A to 1 </ b> I may be used. The same shall apply hereinafter) are combined. Alternatively, two or more building units 1R (in place of the building unit 1R, any symmetric body of the building units 1A to 1I may be used. The same shall apply hereinafter) are combined. Alternatively, one or more building units 1 are combined with one or more building units 1R. Alternatively, one or more rectangular parallelepiped building units 80 and one or more building units 1 are combined. One or two or more rectangular parallelepiped building units 80 are combined with one or more building units 1R. Alternatively, one or two or more rectangular parallelepiped building units 80, one or two or more building units 1 and one or two or more building units 1R are combined. Various combinations as described above improve the diversity of the shape of the unit type building.
Hereinafter, some examples will be described.

  As shown in FIG. 19, if two building units 1 and 1 and two building units 1R and 1R are used, a large space S1 having no pillar in the center can be formed as shown in FIG. . That is, the first pillars 11 and 11 of the building units 1 and 1 are arranged at a diagonal of the rectangle, the first pillars 11 and 11 of the buildings 1R and 1R are arranged at another diagonal of the rectangle, and the rectangular short side The third pillars 13 and 13 of the building units 1 and 1R adjacent to each other are adjacent to each other, the second pillars 12 and 12 of the building units 1 and 1R adjacent to each other along the short side of the rectangle are adjacent to each other, and the building unit 1 The oblique sides of the building units 1 and 1 face each other, and the oblique sides of the building units 1R and 1R face each other. A space S1 formed inside the building units 1, 1, 1R, 1R is a large space S1 having no pillar in the center. An upper part of a normal rectangular parallelepiped building unit 80 or the like can be provided on any of the building units 1, 1, 1R, and 1R.

  In the example shown in FIG. 19, the building units 1, 1, 1R, 1R are arranged on the front, back, left and right so that the outer shape is rectangular in plan view. It arrange | positions so that the beam 33, ... may comprise a rhombus side. If the building units 1, 1, 1R, 1R are arranged in this way, the space S1 formed inside the building units 1, 1, 1R, 1R inevitably becomes a large space without a column in the center. If the building units 1, 1, 1 </ b> R, 1 </ b> R are arranged, a large space without a column at the center can be formed in the unit type building 50 without using, for example, a conventional reinforcing beam. As a result, it is possible to easily construct a unit type building 50 having a configuration that is difficult to achieve with only a normal rectangular parallelepiped building unit 80 formed in a substantially rectangular parallelepiped shape.

  If three building units 1, 1, 1R are used, as shown in FIG. 20, it is possible to form a large space without a pillar in the corner. The arrangement of building units 1, 1, 1R shown in FIG. 20 is obtained by removing one building unit 1R from the arrangement of building units 1, 1, 1R, 1R shown in FIG. The space S2 formed inside the building units 1, 1, 1R is a large space that is substantially L-shaped in plan view and has no pillars in the substantially L-shaped corner portion La. A direct upper part of a normal rectangular parallelepiped building unit 80 or the like can be provided on any of the building units 1, 1R, 1R.

  In the example shown in FIG. 20, the building units 1, 1, 1 </ b> R are arranged in the front / rear / left / right direction so that the outer shape is substantially L-shaped in plan view. If three building units 1 are arranged in this way, the space S2 formed inside the building units 1, 1, 1R inevitably becomes a large space without a column in the corner portion La. If the three building units 1, 1, 1R are arranged in this way, a large space having a substantially L shape in plan view can be formed in the unit type building 50 without using, for example, a conventional reinforcing beam. Can do. As a result, it is possible to easily construct the unit type building 50 having a configuration that is difficult to realize with the normal rectangular parallelepiped building unit 80 formed in a substantially rectangular parallelepiped shape.

  As shown in FIG. 21, when two building units 1 and 1 and two building units 1R and 1R are used, a unit type building having a rhombus shape in plan view is constructed. That is, the first pillars 11, 11, 11, and 11 of the building units 1, 1, 1R, and 1R are placed at the center of the rhombus shape, and the oblique ceiling beams 33 and 33 of the building units 1 and 1 are arranged on one side of the rhombus shape. The oblique ceiling beams 33, 33 of the building units 1R, 1R are placed on the other side. Then, the short sides of one building unit 1 and one building unit 1R are adjacent to each other, the short sides of the other building unit 1 and the other building unit 1R are adjacent to each other, and one building unit 1 and the other building unit are adjacent to each other.
