FIBER REINFORCED RESIN WALKWAY
To provide an FRP walkway with fewer parts of the main girder and easy to secure strength of the main girder.SOLUTION: There is provided FRP walkway comprising a main girder 1, a support pillar 2 erected on both sides of the main girder 1, and a handrail 3 attached to the support pillar 2, in which the main girder 1, the support pillar 2 and the handrail 3 are each formed of FRP. The main girder 1 is formed of a hollow plate shape composed of a surface portion 11, a back surface portion 12 and both side surface portions 13. By using an integrally molded product having ribs 14 extending in the longitudinal direction between the surface portion 11 and the back surface portion 12 at a plurality of positions in the width direction, the number of parts of the main girder 1 can be reduced and the strength of the main girder 1 can be secured easily as compared with the case of using a main girder integrating a plurality of parts.SELECTED DRAWING: Figure 4
【課題】主桁の部品点数が少なく、かつ主桁の強度を確保しやすいＦＲＰ製歩廊を提供する。【解決手段】主桁１と、主桁１の両側に立設される支柱２と、支柱２に取り付けられる手摺３とからなり、その主桁１、支柱２および手摺３がそれぞれＦＲＰで形成されているＦＲＰ製歩廊において、その主桁１として、表面部１１と裏面部１２と両側面部１３とからなる中空の板状をなし、幅方向の複数箇所に表面部１１と裏面部１２との間で長手方向に延びるリブ１４を有する一体成形品を用いることにより、複数の部品を一体化した主桁を用いる場合に比べて、主桁１の部品点数を減らすことができ、主桁１の強度の確保も容易に行えるようにしたのである。【選択図】図４
