Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof of a middle- and low-rise house, and more particularly, to a structure of a dormitory and a gabled roof whose area under the eaves can be freely selected.

[0002]

2. Description of the Related Art As shown in FIG. 7, a gabled roof of a general medium-to-low-rise house has a rafter 55 fixed to a column 51, a beam 52, and a girder beam 53 on the column 51. Supporting bundle 5
4 is provided in necessary parts). The dimension from the outer wall surface 59 around the house to the tip of the gutter (not shown) of the eaves, that is, the protruding dimension 58 of the eaves is made constant so that the height of the tip of the roof is the same everywhere.

[0003]

Recently, in urban areas, there has been a demand for housings that maximize the use of a limited site that has many restrictions and an appearance that matches a mature cityscape. I would like to build a high-class house on a small site with a dormitory or gable roof as the exterior. At this time, it is necessary to freely combine the protruding sizes of the eaves. For example, when the outer wall surface comes close to the boundary line of the site, the eaves extension dimension must be eliminated or shorter than the eaves extension dimension of other outer wall surfaces. In addition, in order to effectively use the eaves space on the outer wall of the south side, 1
There is also a growing need to make it about m or more than 1 m.

In the above-mentioned conventional house, when it is attempted to change the eaves size for each outer wall surface in order to meet such needs,
Since it is necessary to extend a rafter with a downward slope from a girder with a constant height, the height of the eaves varies, which makes the house aesthetically unfavorable. Moreover, in order to extend the strength rafters for a long time, the rafter cross section must be enlarged. Also, the types of rafters must be diverse.
As the number of types of rafters increases, many problems arise, such as the roof nose piece, the installation of gutters, and the simplicity of eaves processing. Naturally, the number of parts is also large, which causes many problems in terms of cost and construction work. Furthermore, in terms of living environment,
Since the tip of the eaves is lowered, the lighting under the eaves deteriorates, which also obstructs ventilation. The present invention, while the height of the eaves tip of the house is the same, while freely selecting the protruding size of the eaves, the roof and especially the eaves position can be arranged without being restricted by the position of the skeleton. It provides a roof structure for a house.

[0005]

The present invention is as follows. The first nose tip beam is arranged at the tip part of the take-out beam of any size from the first body of the first outer wall of the house, and the beam is brought out on the first body of the first outer wall. A beam with integrated beams is hung, and is placed outside the second outer wall surface of the house opposite to the first outer wall surface, which is parallel to the first outer wall surface, and at a position that is an integral multiple of the module from the first nose tip beam. The second nose beam is arranged to connect the second nose beam by bringing out the nose beam from the second body of the second outer wall surface in accordance with the protruding size of the roof eaves. Is a roof structure in which a roof rafter is arranged between the second nose beam at the same height as.

Further, in the above-mentioned roof structure, in a house having four or more outer wall surfaces, there are two or more types of roof eaves, and the eaves are attached to the ends of carry-out beams fixed to the body. It is a roof structure in which the tip of the rafters of the roof is hung on the nose beam or frame girder beam.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view of one embodiment showing the design, construction and roof structure of the present invention, FIG. 2 is a detailed view of the first outer wall surface side of FIG. 1, and FIG. 3 is a second outer wall surface of FIG. FIG. 4 is a detailed view of another embodiment, FIG. 4 is a detailed view of another embodiment, FIG. 5 is a view of an embodiment showing the relationship between the outer wall surface of the house and the tip of the eaves, and a floor plan of the roof, and FIG. It is a detailed view at the time of making the protrusion size of the eaves minimum in the example.

FIG. 1 shows a cross section of a house cut in north and south. The first outer wall surface 11 is on the north side, and there is no room on the site, and the projecting dimension of the eaves, that is, the size from the outer wall surface to the tip of the gutter (not shown in all the figures below) is not so large, and is about 85 cm. . The second outer wall 12 is on the south side, and the eaves have a protruding size of about 207 in order to form a roofed veranda under the eaves.
It is in cm. In this house, first, a skeleton position is determined, and a take-out beam 17 having an eave-out size is arranged from the first outer wall surface 11 side of the first skeleton 15 to the north side. Then first on the tip
The nose bridge 13 is placed. A second nose beam 14 is arranged at a position that is an integral multiple of the module from the first nose beam 13 and becomes the roof tip of the south veranda on the opposite side of the house, and the second nose beam and the second frame A take-out beam 17 is arranged between 16. After that, hang a rafter. In this way, at least the projecting size of the eaves on the north side can be freely selected. That is, it becomes possible to determine the layout of the roof regardless of the layout of the skeleton.

In this case, if the length of the take-out beam is set to an integral multiple of the module, the entire module can be configured by the module. If several types of take-out beams are prepared in advance and the ones that meet the needs are used, the number of parts is reduced, which is advantageous for design and construction. Practically, it is good to prepare 4 to 5 kinds of take-out beams with the eaves' extension size of about 60 cm to 180 cm. In this embodiment, the module is 30.5 cm, and the length of the take-out beam, that is, the distance between the girder beam and the tip of the nose beam is an integral multiple of the module.

If the projected size of the eaves on the north side is desired to be as small as possible, the girder beam of the first skeleton 15 may also serve as the first nose tip beam 13 and the carry-out beam 17 may be omitted. In this case, the protruding size of the eaves is about 24 cm. An example thereof is shown in FIG. Then, the leading end of the rafter 5 is hung on the take-out beam 17 or the nose beam 13 attached to the take-out beam 17 to complete the roof. The rafter may be a rafter of a panel made of a plurality of rafters or a rafter of a panel made of a rafter and a face material.

FIG. 2 is a detail of the north side of FIG. In the frame, a beam 2 and a girder beam 3 are fixed to the side surface of a pillar 1. Furthermore, this pillar 1
Alternatively, the carry-out beam 7 is fixed to the girder beam 3, and the nose beam 6 is fixed to the tip thereof. A bundle 4 is fixed to the beam 2 and the nose beam 4, and a rafter 5 is hung on it. The gutter at the tip of the rafter 5 serves as the tip of the eaves, and the dimension from the outer wall surface 9 is the protruding dimension 8 of the eaves.

FIG. 3 is a detailed view of the south side of FIG. 1 and has the same contents as FIG. 2 except that the protruding size 8 of the eaves and the length of the carry-out beam 7 are different. In this example, the bundle 4 is not at the tip of the rafter 5.

FIG. 4 has substantially the same size and configuration as FIG. 2, but the structure of the frame is such that the beam 2 and the carry-out beam 7 are integrated on the pillar 1. This is more advantageous in construction than retrofitting the take-out beam, and the number of parts can be reduced. In this case, the girder beam 3 is connected to a beam in which the beam 2 and the carry-out beam 7 are integrated.

FIG. 5 is a plan view of the house, and A is an eaves tip 10.
The relationship between the outer wall surface 9 and the outer wall surface 9, that is, the eaves projection size 8 differs depending on the location of each outer wall surface, and is also shown as a floor plan. The ridgeline 18 of the roof is shown to consist of ridges and valleys.

B indicates that the outer circumference of the eaves tip 10 can be made rectangular (shaped) even if the outer wall surface 9 has a complicated shape. That is, according to the present invention, the roof can be simply shaped regardless of how complicated the outer wall surface of such a skeleton is. In this example, the ridge 18 has an extremely simple roof without a valley.

C is an example of the floor plan in the wall surface. In short, it is an example of a flat surface of a house in which the height of the tip of the eaves is the same and the protruding size of the eaves is changed to achieve the above object.

As can be seen from this example, the flat surface of an ordinary house is rarely rectangular, that is, the outer wall surface has six or more surfaces, and accordingly, the eaves may have three or more kinds of sizes. In many cases, applying the present invention is advantageous in design and construction.

FIG. 6 shows an embodiment in which the carry-out beam is omitted in the description of FIG. The point is that the girder beam 3 also functions as a nose beam. Such needs are extremely high in urban areas.

Although the above example has been described based on a steel frame house, the present invention can also be applied to a wooden structure. However, in terms of the strength of the material, it is more advantageous to apply it to a steel frame system. The present invention can be applied to a dormitory and a gabled roof, but it is the dormitory that makes it easy to exert an aesthetically superior effect by making the eave tips the same height.

[0020]

EFFECTS OF THE INVENTION According to the roof structure of the present invention, the eaves can be freely combined in size while the height of the eaves is the same, so that the limited site can be maximized.
Moreover, it is not inferior in terms of aesthetics.

In the present invention, since the roof can be shaped, the roof can be made large and the building can be magnificently seen, which is aesthetically advantageous. In addition, the roof structure can be simplified, and the valley portion, which is a weak point of the waterproof surface of the roof, can be reduced or eliminated, so that the house can be provided with no waterproof defect. As a result, it becomes possible to provide more durability.

The present invention can solve all the problems described above. That is, it is technically superior in construction and structure, and having several types of eaves dimensions without changing the height of the eaves means that the environment of the room under the eaves depends on the length of the eaves dimension. Not only can we do well, but we can also provide housing that meets the needs of future housing such as aesthetics.
