Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a roof eave member that is provided at the eave end of a horizontal roof to hold a tip roof board.

<Prior Art> As is well known, when a roof is constructed by horizontally covering roofing sheets, the front end of the roofing sheet located at the tip of the eaves must be fixed to a member for the eaves.

Therefore, conventionally, a member for the eaves is fixed to the tip of the rafter, and the tip of the roof board material is latched to the eave edge member.

As the above-described member for the eaves, there is, for example, one described in Japanese Utility Model Application Publication No. 60-28133.

Further, in the eaves using the conventional eaves eaves member, a step is formed because the fascia and the outer wall are located at the rear of the eaves eaves member due to the structure of the eaves eaves member.

<Problems to be Solved by the Invention> However, with the above-mentioned conventional members for the eaves, it is not possible to securely secure the roofing board with high strength, and the roofing board may be rolled up by strong winds. This also made it difficult to position the front end of the roofing board when laying the roofing board.

In addition, if a worker stands on the eaves and a vertical load is applied, there is a risk that the upper end of the eaves member may break through the roof shingles. Furthermore, the above-mentioned structural steps appear large when viewed diagonally from below, which is extremely unsightly in terms of appearance, and particularly in modern buildings, this significantly reduces the value of the building.

Furthermore, since it is difficult to attach a decorative board to the surface of the eaves member, the aesthetic appearance is also impaired from this point of view. Furthermore, eavestrough members having complicated cross-sectional shapes cannot be produced because they are subject to mold restrictions during molding.
