Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roof with balconies, and more particularly, to a roof with balconies in which inclined roof surfaces inclined from the ridge toward the eaves are provided on both sides of the ridge, and balconies are provided at the ends in the ridge direction.
[0002]
[Background]
Many roofs of buildings have inclined roof surfaces that are inclined from the ridge toward the eaves, and gable roofs, side roof roofs, and the like in which the inclined roof surfaces are provided on both sides of the ridge are known.
In such a roof, in order to effectively use the internal space of the building, the back space may be used as a living room.
In the attic space, which is considered to be a living room, lighting and ventilation are required, and in particular, when the living room in the attic is on the third floor of the building, the building becomes a three-story building, facing the road. It is necessary to provide an emergency entrance that can safely reach the backroom of the hut on the third floor.
[0003]
For this reason, a balconi is provided on the roof so that it can enter and exit the cabin space from outside the building.
At this time, when providing a balconi on the gable face of the gable roof, as shown in FIG. 3 , a cantilever ridge 91 is provided on the gable face 9 </ b> A of the gable roof 9 so as to enter and exit the shed space. This cantilevered cone 91 is constituted by cantilevering a balconi unit assembled in advance at a factory or the like on the end face 9A (see Japanese Patent Laid-Open No. 4-261932).
[0004]
On the other hand, the cantilever cone 91 described above cannot be provided on the close-up roof because there is no gable face like the gable roof 9.
For this reason, when providing a balconi on the roof of the close-up building, a part of the roof can be used as a roof balconi so that it can enter and exit the shed space.
That is, the roof is constructed by arranging an inclined roof portion having a roof space and a roof balcony on the building body.
[0005]
[Problems to be solved by the invention]
However, since the above-mentioned cantilever 91 has a cantilever support structure, the durability against load is relatively small, and the dimensions in the protruding direction (building direction) from the end face 91A and the dimensions in the end direction are limited. There was a problem that the area of Balconi could not be secured sufficiently.
In addition, when a part of the roof is a roof balcony, one roof is composed of two different types of structures, an inclined roof and a roof balcony, which complicates the roof structure. There was a problem.
[0006]
The objective of this invention is providing the roof with a balcony which can provide the balconi of sufficient width by a simple structure.
[0007]
[Means for Solving the Problems]
The present invention will be described with reference to the drawings. Inclined roof surfaces 13 inclined from the ridge 11 toward the eaves edge 12 are provided on both sides of the ridge, and a balconi 4 is provided at the end in the ridge direction. The roof with balconies 10 and 50, and the balconi 4 includes a cantilever part 4A protruding outward from the outer wall and a roof balcony part 4B provided on the indoor side from the outer wall. These cantilever parts 4A and roof balcony part 4B are united to form a balconi space, and the eaves 32 arranged along the eaves edge 12 are lowered from the edge of the ridge along the edge of the inclined roof surface. wherein a pair of diagonal structural members 33 that are coupled to the ends of the eaves geta 32, and a support member 34 which is bridged between the lower ends or between the vicinity of the lower end portion of these diagonal structural members, wherein this support Wherein the floor 40 of Rukoni is supported.
[0008]
In the present invention, since a support material is bridged between the lower end portions of the diagonal structural material which is the structural material of the roof, and the floor of the balconi is supported on this support material, excellent durability against load can be obtained. The balconi is not limited to a small size, and the balconi can be formed sufficiently wide.
Further, since the support material is constructed between the diagonal structural materials as the structural material of the roof, it can be used as both the structural material of the roof and the framework of the balcony. Therefore, unlike the conventional roof balcony, it is not necessary to incorporate a special structure for the balcony in order to form the balcony on the roof. Therefore, the balcony can be provided with a simple structure.
Furthermore, since the balconi is formed over the outer wall, the size of the balconi can be sufficiently secured.
[0009]
In this case, the roof with a balcony is a gable roof whose end in the ridge direction is a wife surface 14 orthogonal to the inclined roof surface, and the balconi is a hut back surrounded by the inclined roof surface and the wife surface. It may be provided in a space and open to the wife surface.
[0010]
Alternatively, the roof with a balcony is a roof ridge roof formed as a wife side roof surface 54 whose end in the ridge direction is inclined, and the balconi is in a shed space surrounded by the inclined roof surface and the wife side roof surface. It may be provided and may open to the wife side roof surface.
Thus, if the balconi is provided in the cabin space, the balconi can be formed without impairing the outer shape of the roof.
[0012]
In the above, each floor of the cantilevered part and the roof balcony part is supported by a common joist 41 provided continuously to these balconies, and the end part of the joist is connected to the support material. It is desirable.
In this way, by sharing the joists of the cantilever and the roof balcony parts, the number of members can be reduced and the assembly work of the balcony can be facilitated.
Moreover, since the edge part of joist is connected with the support material, the floor of a balconi can be reliably supported by a support material.
[0013]
In the above, it is preferable that the drain hole 43 for discharging water is formed in the vicinity of the longitudinal end portion of the support member in the floor of the balconi.
[0014]
Thus, the drainage hole is formed in the vicinity of the end of the eaves by forming the drainage hole in the vicinity of the longitudinal end of the support member. Since the end of the eaves is close to the corner of the building body 2 provided under the roof, the drainage hole is formed near the corner of the building body.
Therefore, the drainage path can be shortened because the water of the balconi can be drained along the corners of the building body without interfering with the external equipment such as the windows 22 and 23 just by guiding the water of the balconi downward. And can be designed easily.
[0015]
Moreover, it is desirable that a living room is formed in the attic space covered by the inclined roof surface, and a window portion 15 is provided at a boundary portion between the living room and the balcony.
If it does in this way, sufficient lighting and ventilation can be ensured in the room of a hut space through a window part.
[0016]

[0024]
According to this embodiment, there are the following effects.
That is, since the support member 34 is bridged between the lower end portions of the oblique structure member 33 that is the structure member of the roof 10 and the floor 40 of the balconi 4 is supported on the support member 34, the durability against load is excellent. Thus, the balconi 4 is not limited to a small size, and the balconi 4 can be formed sufficiently wide.
[0025]
Further, since the support member 34 is constructed between the diagonal structural members 33 as the structural member of the roof 10, it can be used as both the structural member of the roof 10 and the framework of the balcony 4. Therefore, unlike the roof balcony, it is not necessary to incorporate a special structure for the balcony in order to form the balcony, so that the balcony 4 can be provided with a simple structure.
[0026]
Furthermore, since the balconi 4 is provided in the shed space surrounded by the inclined roof surface 13 and the wife surface 14, the balconi 4 can be formed without impairing the outer shape of the gable roof.
[0027]
Moreover, since the balconi 4 is formed by integrating the cantilevered part 4A and the roof balcony part 4B and is formed across the end face 2A of the building body 2, the size of the balcony 4 can be sufficiently secured.
Further, since the joists 41 of the floor 40 of the balconi 4 are shared by the cantilevered balconies 4A and the roof balconies 4B, the number of members can be reduced and the assembly work of the balconies 4 can be facilitated.
Moreover, since the edge part of the joist 41 is connected with the support material 34, the floor 40 of the balconi 4 can be reliably supported by the support material 34.
[0028]
And since the drain hole 43 of the balconi 4 is formed in the longitudinal direction end part of the support material 34 of the floor 40, the drain hole 43 is formed in the vicinity of the end part of the eaves edge 12. Since the edge part of this is close to the corner | angular part of the building main body 2, the drainage hole 43 comes to be formed in the corner | angular part vicinity of the building main body 2. FIG.
Accordingly, the water of the balconi 4 can be flowed down along the corners of the building body 2 without interfering with the external equipment such as the windows 22 and 23 only by guiding the water of the balconi 4 from the drainage hole 43 to the lower side through the ridge 44. The drainage path can be shortened and designed easily.
[0029]
Further, a living room (not shown) is formed in the attic space, and a window portion 15 is provided at the boundary between the living room and the balcony 4, so that sufficient lighting is provided to the living room in the attic space through the window portion 15. And can secure ventilation.
