The present invention improves the workability of the time all the time, entanglement of the coating material, crack, supporter of extremely economical wire and the coating material to eliminate the fear of wear, etc., support tool mounting strut, to provide a stretched timber. The A top surface to the position of the lower end from the upper part of the hemisphere surface 11 of the semi-spherical surface 11 shaped to buildup bulge is made of synthetic resin substrate 10 was, it passes under a vertical of the spherical surface of the vertex 13, is inserted through the through hole 2 on the wire 3 in the upper portion of the support 1 provided with a through hole 2 which crosses the padding portion 12, a support column 4 is attached to the fitting portion 14 provided in the lower part, these heavenly It stretched a coating material 5 of the net-like to drive. .BACKGROUND【課題】始終時の作業性を向上させ、被覆材の絡み、破れ、摩耗等の危惧を解消する極めて経済的な線材と被覆材の支持具、支持具装着支柱、展張用材を提供する。【解決手段】上面を半球面11状に肉盛り膨出させた合成樹脂製の基材10の半球面11の上側部から下側端部の位置に、球面の頂点13の垂直下を通り、肉盛り部12を横断する一つの貫通孔2を設けた支持具1の上側部の貫通孔2に線材3を挿通し、下部に設けた嵌合部14に支柱4を装着させ、これらの天部にネット状の被覆材5を展張する。【選択図】図1
