INSTALLATION STRUCTURE OF LIGHTWEIGHT COVERING PLATE

To provide an installation structure of a lightweight covering plate that is highly versatile, can be used in various places, and facilitates accurate installation without misalignment with respect to a target location to be covered.SOLUTION: A lightweight covering plate 1 includes a rectangular flat top plate, a rectangular flat bottom plate, a plurality of columnar first reinforcement materials whose upper surface and lower surface are respectively joined to the top plate and the bottom plate, and a plurality of second reinforcement materials whose upper surface and lower surface are respectively joined to the top plate and the bottom plate, in which the top plate, the lower plate, the plurality of first reinforcement materials, and the plurality of second reinforcement materials are all made of a fiber reinforced plastic. The lightweight covering plate is bridged between a plurality of receiving members 30 arranged at intervals from each other. A positioning part 20 for positioning the lightweight covering plate in a bridging direction when the lightweight covering plate is bridged between the plurality of receiving members is formed along the plurality of receiving members on the lower surface of the bottom plate.SELECTED DRAWING: Figure 5 【課題】汎用性に優れて様々な場所で活用でき、覆工すべき対象箇所に対して位置ずれなく正確に設置しやすくする軽量覆工板の設置構造を提供する。【解決手段】矩形平板状の上板と、矩形平板状の下板と、上面及び下面がそれぞれ上板と下板に接合された柱状の複数の第一補強材と、上面及び下面がそれぞれ上板下板に接合された複数の第二補強材と、を備え、上板と、下板と、複数の第一補強材と、複数の第二補強材が、いずれも繊維強化プラスチック製とされた軽量覆工板１が、互いに間隔を空けて配置された複数の受部材３０間に架け渡されており、下板の下面には、軽量覆工板が複数の受部材間に架け渡された場合の架け渡し方向において軽量覆工板の位置決めを行うための位置決め部２０が、複数の受部材に沿うようにして設けられている。【選択図】図５
