HORIZONTALLY ROOFING ROOF BOARD MATERIAL
PROBLEM TO BE SOLVED: To provide a horizontally roofing roof board material for simplifying a shape in a ridge directional joint part of a roof board material and improving waterproofness thereof.SOLUTION: A horizontally roofing roof board material comprises a pair of left-right short side parts 1a and 1b and a pair of long side parts 1c and 1d, and constitutes a roof board material body 1. A ridge side long side part is provided with a lower seam 2 fittable to the roof board material adjacently arranged along the eaves or ridge direction, and an eaves side long side part is provided with an upper seam 3 fittable to the lower seam 2 of the roof board material adjacently arranged along the eaves or ridge direction. A lower joint 4 is provided in one short side part. The lower joint 4 comprises at least one projection strip 6b extending toward the lower seam 2 or the upper seam 3 and a pair of recessed strips for sandwiching the projection strip 6b on both sides, and forms one or more horizontal groove(s) 8 respectively communicating with the pair of recessed strips by crossing the projection strip 6b in its width direction. In the horizontal groove 8, a groove side wall positioned on the long side part 1c side provided with at least the upper seam 3, has a downward pitch inclined toward a central part in the longitudinal direction in a plan view of the roof board material body 1.
【課題】屋根板材の桁行き方向継手部分における形状の簡素化、防水性の改善を図る横葺き用屋根板材を提供する。【解決手段】横葺き用屋根板材は、左右一対の短辺部１ａ、１ｂと、一対の長辺部１ｃ、１ｄとを有し、屋根板材本体１を構成する。棟側の長辺部に、軒乃至棟方向に沿って隣接配置する屋根板材に嵌合可能な下ハゼ２を設け、軒側の長辺部に、軒乃至棟方向に沿って隣接配置する屋根板材の下ハゼ２に嵌合可能な上ハゼ３を設ける。一方の短辺部に下継手４を設ける。下継手４は、下ハゼ２乃至上ハゼ３に向けて伸延する少なくも一つの凸条６ｂと、凸条６ｂを両側に挟む一対の凹条を備え、凸条６ｂをその幅方向に沿って横断して一対の凹条にそれぞれ連通する一または二以上の横溝８を形成する。横溝８には、少なくとも上ハゼ３が設けられた長辺部１ｃ側に位置する溝側壁が、屋根板材本体１の平面視において長手方向中央部へ向けて傾斜した下り勾配を有する。【選択図】図７
