PROBLEM TO BE SOLVED: To impart weed-proof function easily and at a low cost to a concrete block with a bottom surface on the side for imparting weed-proof function shallow from a road surface without causing strength degradation.SOLUTION: A weed-proof plate 1A comprises a weed-proof guide part 10 provided to the outer peripheral surface side of boundary blocks 50 and 60 in close contact with a road surface formation material and exhibiting weed-proof function by using phototropism and geotropism of weed. The weed-proof plate is shaped by bending a rectangular flat plate at a folding line 10a that extends over the entire length of a longer direction in a midway position of a short side direction so as to make an obtuse inner angle. With the folding line 10a as a boundary, one flat plate part is an inserted fixing part 11 inserted from the side of the boundary blocks 50 and 60 placed on an installation position into the space between the bottom surface of the blocks and an installation surface to be fixed, and the other flat plate part is the weed-proof guide part 10 that is buried in the road surface formation material in a state of being bent in an obliquely upward direction with the folding line 10a as a starting point from the inserted fixing part 11 fixed horizontally and that exhibits weed-proof function.SELECTED DRAWING: Figure 3
【課題】防草機能を賦与する側の底面が路面から浅くなるコンクリートブロックに対し強度低下を招くことなく低コストで容易に防草機能を賦与する。【解決手段】路面形成材と密着する境界ブロック５０，６０の外周面側に付設されて雑草の屈光性及び屈地性を利用して防草機能を発揮する防草誘導部１０を備えた防草板１Ａであって、その形状を長方形の平板を短径方向中途位置で長手方向全長に亘る折り線１０ａで鈍角の内角となるように屈曲してなるものとし、折り線１０ａを境界として、一方の平板部分が設置位置に置いた境界ブロック５０，６０の側方からその底面と設置面との間に挿入して固定される挿入固定部１１となり、他方の平板部分が水平に固定された挿入固定部１１から折り線１０ａを起点にして斜め上向きに屈曲した状態で路面形成材中に埋設されて防草機能を発揮する防草誘導部１０となるものとした。【選択図】図３
