[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a house eaves part capable of expanding the indoor space by providing a house space below the eaves part by using a connecting beam for supporting a roof panel.

[0002]

2. Description of the Related Art In recent years, houses of so-called panel construction method, in which walls, floors and the like are formed by using panels, have been widely used. The roof of a house of such a panel construction method is also formed by using a so-called roof panel, and the roof panel p is arranged with a slope on the upper end of the roof beam a via a support bracket b as shown in FIG. In addition, the eaves tip e of the roof panel p protruding outward from the roof beam a is supported by a joint beam b having an inner end bolted to the roof beam a and extending toward the eaves at the same inclination as the roof panel p. Was there.

On the other hand, in recent years, it has been proposed that a wall panel pw forming the outer wall of a house is built near the eaves tip e of the roof panel p to expand the indoor space and improve the habitability. .

[0004]

However, in the conventional structure as shown in FIG. 4, the roof beam a supports the upper end of the wall panel pw and the eave ceiling c is arranged below the joint beam b. Has no simple means for locating and building the wall panel pw near the eaves tip e, and therefore the wall panel pw
There has been a strong demand for the appearance of a novel structure that can easily achieve the above-mentioned construction.

According to the present invention, a plurality of joint beams having inner ends bolted to a roof beam and supporting a roof panel and extending toward the eaves of the roof, and a front beam extending at a tip of the joint beam in parallel with the roof beam are provided. In addition to being connected by connecting metal fittings, the front beam supports the upper end of the wall panel that forms the outer wall of the house space provided below the eaves of the roof, and the wall panel has a simple structure using a joint beam. The purpose is to provide the structure of the front of the house that can be built outside and can expand the indoor space.

SUMMARY OF THE INVENTION The present invention is a structure of a house eaves part in which a house space is provided below a eaves part of a roof formed by arranging a roof panel at the upper end of the roof beam so as to protrude from the roof beam. A plurality of joint beams having inner ends bolted to the roof beam and supporting the roof panel and extending toward the eaves, and a front beam extending at the tip of the joint beam in parallel with the roof beam. The beam and the front beam are connected to each other by connecting metal fittings having mounting pieces bolted to each other, and the front beam supports an upper end of a wall panel forming an outer wall of the house space.

[0007]

[Function] A house space is provided below the eaves portion of the roof formed by arranging the roof panel so as to extend from the roof beam. An upper end of a wall panel forming an outer wall of the house space is supported by a front beam having an inner end bolted to the roof beam and coupled to a joint beam supporting the roof panel with a connecting fitting. In this way, since the front beam that supports the upper end of the wall panel is arranged by using the joint beam for supporting the roof panel, the house space can be formed with a simple structure, and the indoor space can be constructed without impairing the workability. Can be expanded.
