た。Further, as a trough for the roof, a trough plate extending over the valley side edge portions of two sets of roof materials is arranged below the facing edge portion to prevent rainwater flowing down the two sets of roof materials. In some cases, water was collected on the valley plate and discharged from the roof eaves into a gutter or the like.

ある。Generally, the valley part of the roof is a part where the lower parts of two sets of roof material gather, rainwater and snow flowing down the two sets of roof material are concentrated, and other than the valley part. Often has a gentler slope than the roofing material. For this reason, water leaks easily to the indoor side in the valley of the roof, and like the conventional roof described above, a water leak prevention plate is placed below the roof material via the space for drainage. Even if you prevent water leakage,
Water leakage may occur in the valley part of the roof in the conventional trough.

題点があった。In other words, in the conventional roof troughing, the valley side edge of the roof material made of a metal plate is raised or folded down to be engaged with the side edge of the valley plate. There is a lot of reliance on it, and it is easy for water to leak from the joint between the roofing material and the valley plate to the inside due to poor construction. In addition, the troughs are often spliced in the longitudinal direction, water leakage occurs in the spliced portion, and further, the troughs are partially damaged during a windstorm, resulting in water leakage. In particular, when tiles or natural slate is used as a roofing material and these are roofed in a building with a steel frame structure, or in the case of a roof in a special environment where the connection of the roofing material is flooded in a snowy area, water leaks into the valley. There was a problem that was frequent.

You can surely prevent this water from leaking to the inside of the valley,
It is an object of the present invention to provide a trough housing structure suitable for a roof in which water leakage such as tiles is likely to occur and a roof in an environment where the connection portion of the roof material is flooded.

Water leak prevention so that both sides of the valley plate for water leak prevention overlap
A trough plate is provided, and both side portions are connected to the base member.
Supported and fixed on top, between the valley plate and the water leakage prevention plate
The water leakage prevention plate above the drainage space and to the eaves section.
Since a space for drainage is formed , even if water such as rainwater leaks below the valley plate arranged below the back surface of the valley-side facing edges of the two pairs of roof materials that sandwich the valley , it leaks. Water should be stored in the drainage space using the water leakage prevention troughs or water leakage prevention troughs and edge ridges.
The water leak prevention plate has a portion near the water leakage prevention valley plate and flows down , so the water that leaks due to water leakage can be reliably discharged from the eaves of the drainage space to the outside of the roof. To be done . Obey
Part of the valley plate due to poor construction or storms.
Even if water such as rainwater enters the bottom of the valley plate ,
It is possible to reliably prevent the water from leaking into the interior of the valley.

It is connected to the eaves part above the drainage space of the water leakage prevention plate.
Since a large space is formed, there is no risk of water stagnation between the valley plate and the water leakage prevention plate due to the capillary phenomenon.
Ri, water Mori prevention for the valley plate is less susceptible to the adverse effects of moisture.
