Description

  The present invention is applicable to various roof surfaces or wall surfaces regardless of whether they are newly installed or repaired, and relates to a side-facing exterior structure that is constructed from the eave side toward the ridge side and a construction method thereof.

The construction of the horizontal roof is mainly done from the eave side to the ridge side, but for various reasons, a construction method has been proposed that goes from the ridge side to the eave side.
For example, Patent Document 1 discloses a roof structure that can be constructed from the ridge side toward the eaves side or from the eaves side toward the ridge side. The groove formed in the ridge side molding part of the roof board is elastically fitted.
However, the fitting of the exterior material due to the elasticity limits the material and thickness of the exterior material, and if there is an error in the molding of the exterior material, it causes a fitting failure or the exterior material is deformed to cause rain. There was a problem of being affected. Moreover, in this structure, since the exterior material fitted to the suspension and the exterior material adjacent to the ridge side are assembled to the suspension in a state of being assembled, specifically, at least the goby portion of the two exterior materials It was necessary to assemble a goby in a floating state, and workability was poor.

Patent Document 2 discloses an exterior structure intended to be constructed from the ridge side toward the eaves side, and this exterior structure fits the hanging members by using two hanging members as upper and lower members. The upper suspension is attached to the ridge side molding portion of the exterior material, and the exterior material adjacent to the ridge side is further engaged with the lower suspension.
However, in this construction, the construction is a structure that is fitted to the suspension in a state combined with the exterior material adjacent to the ridge side, and the upper suspension is attached to the ridge side molding portion of the exterior material. In order to engage the exterior material adjacent to the laid side of the ridge, specifically, it is necessary to combine the assembled parts of the two exterior materials in a floating state, and the workability is poor.
In addition, both proposals have a problem that the eaves edge of the exterior material is not attached to the ground during laying, which causes a flutter due to a blowing wind or the like, causing an accident or the like.
