CONCRETE GUARD FENCE
PROBLEM TO BE SOLVED: To provide a concrete guard fence by which a block in the middle of the lengthwise direction can be removed independently and easily.SOLUTION: A concrete guard fence comprises a lower projecting block 2 in which a lower projecting part 5 is protruded at the lower part of both sides of the lengthwise direction, an upper projecting block 3 in which an upper projecting part 6 arranged on the lower projecting part 5 is protruded at the upper part of both sides of the lengthwise direction, and a steel pipe 15 which connects the lower projecting block 2 with the upper projecting block 3 in a state that the upper projecting part 6 of the upper projecting block 3 is arranged on the lower projecting part 5 of the lower projecting block 2. By releasing the connection by the steel pipe 15, the upper projecting block 3 in the middle can be lifted and removed. By removing the upper projecting blocks 3 and 3 on both sides, the lower projecting block 2 between the upper projecting blocks can be lifted and removed.SELECTED DRAWING: Figure 4
【課題】長さ方向途中のブロックを単独で容易に取り外しできるコンクリートガードフェンスを提供する。【解決手段】下張出部5を長さ方向両側下部に突設した下張出ブロック2と、下張出部5の上に配置する上張出部6を長さ方向両側上部に突設した上張出ブロック3と、下張出ブロック2の下張出部5の上に上張出ブロック3の上張出部6を配置した状態で、下張出ブロック2と上張出ブロック3を連結する鋼管15とを備える。鋼管15による連結を解除することにより、途中の上張出ブロック3を持ち上げて取り外すことができる。また、両側の上張出ブロック3,3を取り外すことにより、間の下張出ブロック2を持ち上げて取り外すことができる。【選択図】図4
