SIDE DITCH COVER
To provide a side ditch cover having a drainable and high-strength structure.SOLUTION: A plurality of slender materials 1 are made of FRP and have an I-shaped cross section. Each slender material 1 has an end open hole 1a on the side of each end and two intermediate open holes 1b and 1c on an intermediate part of the side. Each slender material 1 is arranged in parallel with spacing for drainage between the sides. A plurality of end reinforcements 2 are made of FRP and have an end open hole 2a on the side. Each end reinforcement 2 is fitted between the sides of each end of each slender material 1 and is fixed with an adhesive. A pair of core materials 3 is made of FRP, and is fixedly penetrated to the end open hole 1a at both ends of each slender material 1 and the side open hole 2a of each end reinforcement 2. Two interval holding materials 4 pass the intermediate open holes 1b and 1c, and have a plurality of grooves 4a fitted with each slender material 1. Two fixing materials 5 fix the interval holding materials 4 to the intermediate open holes 1b and 1c.SELECTED DRAWING: Figure 1
【課題】排水可能で強度が大きい構造の側溝蓋を提供する。【解決手段】複数の細長材1がFRP製で断面I字型の形状を有する。各細長材1は、両端の側部に端部貫通孔1aを有し、側部の中間部に2つの中間貫通孔1b、1cを有する。各細長材1は、側部間に排水用の間隔をあけて並列に配置される。複数の端部補強材2がFRP製で、側部に側部貫通孔2aを有している。各端部補強材2は、各細長材1の両端の側部間に嵌合され、接着剤で固定されている。1対の芯材3がFRP製で、それぞれ各細長材1の両端の端部貫通孔1aおよび各端部補強材2の側部貫通孔2aに貫通して固定される。2本の間隔保持材4が中間貫通孔1b、1cを貫通し、各細長材1と嵌合する複数の溝部4aを有する。2本の固定材5が間隔保持材4を中間貫通孔1b、1cに固定している。【選択図】図1
