SUBSTRATE CORNER MATERIAL

PROBLEM TO BE SOLVED: To provide a substrate corner material of which a volume is reduced only a little, even when a putty material is dried sufficiently after being smoothed using a putty spatula.SOLUTION: A substrate corner material is a long material disposed along an intersecting line at an internal corner or an external corner where two wall surfaces with a finishing material intersect, and includes a bent part along a central part of the long substrate corner material in a longer-side direction, a pair of flat plate parts formed on both sides of the central part, and a plurality of open holes through front and rear surfaces of the pair of flat plates. All of the plurality of open holes are long holes with a greatest length along the longer-side direction of the long substrate corner material greater than a greatest width in a direction orthogonal to the longer-side direction.SELECTED DRAWING: Figure 2 【課題】 パテベラ等によるパテ剤の平滑化を行って充分に乾燥させた場合でも、ヤセの少ない下地コーナー材を得る。【解決手段】 クロス張りされる２つの壁面が交わる入隅部又は出隅部の交線に沿って配される長尺体である下地コーナー材であって、長尺体の長手方向に沿った中央部に沿った曲折部と、中央部の両側に形成された一対の平板部と、一対の平板部に表裏面を貫通する多数の貫通孔とを備え、多数の貫通孔の全てが、長手方向に直交する方向の最大横幅長に対して、長尺体の長手方向に沿った最大縦幅長が長い長孔であるもの。【選択図】 図２
