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
