[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure in which a vertical frame material of a roof panel can be used as a load bearing material without reducing horizontal rigidity against horizontal force.

[0002]

2. Description of the Related Art As shown schematically in FIG. 7, for example, a roof frame structure a for forming a gable roof includes a plurality of pillars b ...
And a horizontal roof beam c spanned between these pillars b ...
, A plurality of mountain-shaped climbing beams d ... Which are arranged in parallel with the gable face and whose lower ends are supported by the columns b, b, and parallel purlin beams e ... (Including the master beam f).

Further, a brace g for bearing a horizontal force is bridged in an X-shape between the adjacent parallel purlin beams e and e, but as shown schematically in FIG. Conventionally, between the beam e1 and the roof beam c, not a brace, but a tomb house h extending in the direction of the roof inclination is erected, whereby a high horizontal rigidity for bearing a larger horizontal force than other parts is provided on the eaves. It was secured in the vicinity.

[0004]

On the other hand, with the widespread use of so-called panel construction houses in which the roof is formed by using integrally portable roof panels p ..., the frame material of the roof panels p extends in the direction of inclination of the roof. More cases are being distributed.

The present inventor has completed the present invention by paying attention to the fact that the frame material of the roof panel p arranged in the inclination direction of the roof can be used as a substitute for the above-mentioned tomb house h.

That is, according to the present invention, vertical frame members of a plurality of roof panels arranged in the direction of inclination of the roof are arranged next to each other in the house frame structure, and adjacent vertical frame members are located between the climbing beams. The purpose is to provide a roof structure in which vertical frame members can be effectively used as load bearing materials that bear horizontal force, based on bolt connection.

[0007]

In order to achieve the above object, the roof structure of the present invention is a frame structure in which upper and lower ends of parallel vertical frame members arranged in a tilt direction of the roof are joined by horizontal frame members. A plurality of roof panels with field boards attached to the upper surface, vertical frame members side by side, and adjacent vertical frame members are tilted upward from the eaves toward the ridge and supported by the house frame structure. together disposed in a house framework body by the Noboru beams and the inclined is positioned parallel registration Harima, between the Noborihari near the frame member near the longitudinal adjacent only One bolted to vertical frame member the adjacent Place the brace on.

[0008]

Function: Adjacent vertical frame members arranged in the roof tilt direction of a plurality of roof panels are positioned between the climbing beams, and the roof panels are arranged in the house frame structure, and the adjacent vertical frame members are arranged. Connect with bolts. Therefore, the adjacent vertical frame members work in the same way as the conventional climbing house h shown in FIG. 7 between climbing beams, that is, they can bear the horizontal force and can be effectively used as a load bearing material, and the climbing house h is unnecessary. Therefore, the cost can be reduced.

[0009] or the longitudinal frame member near the adjacent for placing a brace between the Noborihari vicinity, with can ensure horizontal rigidity against horizontal force by the the braces and vertical frame member, the brace, Prevents deviation of horizontal force to one vertical frame member.
