Description

  The present invention relates to a building.

  For example, if a 2-story house with a ceiling height of about 2.4m (about 2.8m) in each floor and an LDK with an integrated living room, dining room, and kitchen is provided on the first floor, the outer wall Often, a sweep window is provided at the portion facing the LDK to allow the LDK and the outdoor space to enter and exit. In such a configuration, the LDK and the outdoor space are more integrated, and the resident can effectively use the outdoor space as a place for meals, gatherings, sunbathing, and the like.

  In such a house, a private living room such as a bedroom is mainly provided on the second floor, and a balcony that can be swept out of the living room through a window may be provided to protrude from the outer peripheral wall (for example, the following patent document). 1). A balcony can be made to function as a fence by providing it above the outdoor space mentioned above. Furthermore, in order to adjust the amount of solar radiation to the second-floor room, a ridge may be provided above the sweep-out window so as to overlap the balcony.

JP 2009-91753 A

  In general, the above-described balcony and tub are often set so that the amount of protrusion from the outer peripheral wall is, for example, about half (0.91 m). In such balconies and fences, it is considered that the increase in room temperature can be suppressed by blocking the entry of sunlight with a large incident angle into the room. However, when the incident angle of sunlight is small compared to before and after the summer solstice, such as in the extremely hot season and the remaining summer season (for example, mid-August to mid-September), it is not possible to sufficiently block the sunlight by the balcony or hail. . Also, during the intensely hot and late summer periods, there is a great influence of the reflection of sunlight reflected from the floor of the balcony.

  In order to increase the sunshade effect in the hot and late summer season, if the amount of protrusion of the balcony or ridge directly above the target room is increased unnecessarily, the sun entering the target room will be increased, especially in the winter when the incident angle of sunlight is small. It becomes difficult to ensure the amount of incident light. In addition, if the amount of protrusion of the balcony or ridge directly above the target room is increased, the sky view from the target room or outdoor space is blocked by the balcony or ridge, and there is a problem that the feeling of opening is impaired.

  Therefore, the present invention has been made in consideration of the above-described circumstances, and an object thereof is to provide a building that can improve the indoor thermal environment without impairing the feeling of opening.

  In order to solve the above problems, the present invention employs the following aspects.

The horizontal strength member 95 is provided in each of the first floor portion and the second floor portion of the inside of the east wall portion 10E and the south wall portion 10S.

  As shown in FIG. 2 and FIG. 6, the roof portion 4 of the building 2 is located immediately above the internal space on the second floor (the region surrounded by the outer peripheral wall 10) and covers the main roof portion 100 that covers the internal space on the second floor. , And a protruding portion 101 taken out from the main body roof portion 100. The protruding portion 101 includes a cantilevered roof portion 110 and a flange portion 111. The cantilevered roof part 110 is an extension line of the east side peripheral part (periphery part above the east side wall part 10E) in the main body roof part 100 and an extension line of the south side peripheral part (periphery part above the south side wall part 10S). The main body roof portion 100 and the cantilever roof portion 110 are formed in a rectangular shape in plan view as a whole, and are semi-outdoored. It is possible to cover the entire space 75 from above without standing up pillars or the like.

  The main body roof portion 100 is attached to a roof slab composed of an ALC panel or the like placed on a roof beam spanned by a plurality of second-floor pillars, a heat insulating material laid on the upper surface of the roof slab, and a heat insulating material upper surface. It is comprised with the waterproof sheet etc. which were made. On the other hand, the cantilevered roof part 110 is configured in the same layer configuration as the main body roof part on the cantilevered roof beam formed by bringing out the roof beam constituting the main body roof part 100 in the direction of the cantilevered roof part. Is done. With this configuration, a continuous substantially flat roof surface is formed. Moreover, the main body roof part 100 and the cantilevered roof part 110 are designed on the assumption that people walk or load heavy objects. The upper surface of the cantilevered roof part 110 is used as a part of the power generation space 72 as described above, and the cantilevered roof part 110 contributes not only to control of solar radiation but also to securing and increasing the power generation space. .

  As shown in FIGS. 1 and 4, the eaves portion 111 has an L shape in plan view, and is taken out to the south side and the east side along the two sides on the front end side of the cantilevered roof portion 110. The west side end portion of the buttock 111 is extended to a position reaching the south side rim of the main body roof portion 100, and the north side end portion of the buttock 111 is extended to a position reaching the east side rim of the main body roof portion 100. The amount of protrusion from the tip of the cantilevered roof portion 110 of the flange portion 111 is about 0.8 m, and the amount of protrusion of the entire protruding portion 101 from the main body roof portion 100 (first corner wall portion 81) to the south side is It is about 2.6 m.

  Unlike the cantilevered roof part 110, the collar part 111 is a part that does not assume human walking or loading of heavy objects, and does not require strength or rigidity compared to the cantilevered roof part 110. Therefore, the collar 111 is lighter than the cantilevered roof 110. Moreover, as shown in FIG. 6, the thickness T2 of the collar 111 is thinner than the thickness T1 of the cantilevered roof 110, giving a sharp impression. 2 and 6, the eaves ceiling of the eaves part 111 and the eaves ceiling of the cantilevered roof part 110 are configured using the same material so that no step or seam is generated. It has sex. In addition, the eaves ceiling of the eaves part 111 and the eaves ceiling of the cantilevered roof part 110 are set to be substantially equal to the ceiling surface of the hole 43. Unlike the cantilevered roof portion 110, the collar portion 111 has a relatively simple configuration, and the amount of solar radiation can be adjusted by appropriately adjusting the protruding amount of the collar portion 111 without changing the overall configuration of the building 2 at the time of design. Can be optimized.

  As described above, in the present embodiment, the semi-outdoor space 75 is covered with the cantilevered roof part 110, so that the cantilevered roof part is also used in the extreme heat and remaining heat periods when the incident angle of the sun is smaller than before and after the summer solstice. 110 can suppress the incidence of sunlight into the LDK 23 and the hall 43, and a sufficient awning effect can be obtained. In addition, no balcony or fence is provided immediately above the LDK 23, and the cantilevered roof portion 110 is provided above the hole 43. Therefore, even if the cantilevered roof portion 110 protrudes greatly, sunlight with a small incident angle is generated. It is easy to enter the LDK 23, it is easy to secure the amount of solar radiation in the winter, and the influence of the summer reflection in the hall 43 can be suppressed. Furthermore, by forming a semi-outdoor space 75 defined by continuous walls without balconies or walls from the first floor to the second floor, a balcony or an overhead space is provided directly above the LDK23 (LDK window 86) for awning the LDK23. Compared to the case where a fence is provided, the view of the sky from the LDK 23 is less likely to be obstructed, and an open feeling can be given.

  In addition, since the cantilevered roof portion 110 protrudes in a cantilevered manner, the construction cost can be reduced compared to a configuration in which the tip of the cantilevered roof portion 110 is supported by a pillar or the like, and the semi-outdoor space 75 can be Since no structure is arranged, the semi-outdoor space 75 can be used effectively, and the view can be provided without being blocked by a pillar or the like.

  Moreover, since the upper surface of the main body roof part 100 and the cantilevered roof part 110 forms the continuous substantially flat roof surface in the rooftop floor (the rooftop terrace 71 and the electric power generation space 72), it can make it easy to do a rooftop floor. it can.

  In addition, since the flange 111 that is thinner than the cantilevered roof part 110 protrudes from the tip part of the cantilevered roof part 110, the amount of protrusion of the entire protruding part 101 from the main body roof part 100 can be further increased. The awning effect can be further improved. Moreover, by making the collar part 111 thinner than the cantilevered roof part 110, the weight of the collar part 111 can be reduced and the design of the building 2 can be improved. Furthermore, since the eaves ceilings of the cantilevered roof part 110 and the eaves part 111 are arranged flush with each other, the design of the building 2 can be further improved.

  Moreover, since it was set as the structure by which the photovoltaic power generation panel 73 was installed in the area | region containing the cantilevered roof part 110 among the roof parts 4, compared with the case where a photovoltaic power generation panel is installed only on the main body roof part 100. Thus, it is possible to increase the private power generation amount or to provide the rooftop terrace 71 while maintaining a constant private power generation amount.

  Further, by arranging the first corner wall portion 81 so that the direction indicated by the normal line extending outward from the first corner wall portion 81 coincides with the south direction, the lighting performance into the LDK 23 and the hole 43 is reliably improved. Can be made.

  Furthermore, since the horizontal strength members 95 that restrain the horizontal deformation of the building 2 are provided on the first and second floors of the south side wall 10S and the east side wall 10E, the building 2 around the semi-outdoor space 75 Strength (earthquake resistance) can be secured.

  The technical scope of the present invention is not limited to the above-described embodiments, and includes various modifications made without departing from the spirit of the present invention. For example, in the above-described embodiment, the building 2 has a two-story structure, but the same configuration as that of the above-described embodiment can be applied to two consecutive levels of a three-story or more building. For example, when applied to the second floor and the third floor in a three-story building, an outdoor floor can be provided using the roof portion of the first floor.

  In the above-described embodiment, the lower floor room is an LDK and the upper floor room is a hall. However, the lower floor room and the upper floor room may be rooms for other purposes. In the floor lighting window and the upper floor lighting window, the open / close format may be a sliding format, a slide-out format, an open format, or the like, as long as the glass type has translucency. The height dimension (height from the lower end to the upper end) and the width dimension of the lower-floor daylighting window and the upper-floor daylighting window can also be appropriately changed according to the required daylighting area.

  Moreover, the horizontal direction length of a 1st corner wall part or a 2nd corner wall part is not specifically limited, either. However, in order to ensure a certain degree of blockage, the former is preferably in the range of 2.7 to 5.4 m, and the latter is preferably in the range of 1.5 to 2.0 m. Moreover, the direction of the building may swing from east to west. However, it is preferable that the angle formed between the azimuth indicated by the normal line extending outward from the surface of the first corner wall portion and the south azimuth is within 45 °.

  Moreover, the horizontal strength member should just be provided in the lower floor part of the 1st wall part and the 2nd wall part, and a collar part is 1 direction (for example, the same direction as the extension direction of a 1st corner wall part). It may be taken out only from the side, or may be taken out from a part of one side of the cantilevered roof portion.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modification examples may be appropriately combined.
