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

On the other hand, in recent years, it has been proposed that a wall panel pw forming an outer wall of a house is built near the eaves tip e of the roof panel p to expand an indoor space to 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 new structure that can easily achieve the above-mentioned construction.

According to the present invention, a plurality of joint beams having inner ends bolted to the roof beam and supporting the roof panel and extending toward the eaves of the roof, and a front beam extending in parallel with the roof beam at the tip of the joint beam are provided. While being connected by a connecting metal fitting, the front beam supports the upper end of a wall panel that forms the outer wall of the house space provided below the eaves of the roof. 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 extend 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 in parallel with the roof beam at the tip of the joint 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.
