SCAFFOLD BOARD

To provide a scaffold board lighter and stronger than the conventional one.SOLUTION: For a scaffold board 1, five hollow shape materials made of aluminium extending in a long side direction are arranged in a short side direction and fitted each other and shaped in a board shape. These hollow shape materials are composed of a central material 11 situated in a center of the short side direction, intermediate materials 12, 13 situated at both sides of this central material 11, a first end material 14 situated at one end in the short side direction and a second end material 15 situated at the other end in the short side direction. A fitting part between the central material 11 and the intermediate materials 12, 13 and a fitting part between the intermediate materials 12, 13 and the first end material 14 and the second end material 15 are sliding fitting parts formed slidably in a width direction in the state that the materials are fitted each other. The scaffold board 1 can be formed in a long fan shape in which one short side is shorter and the other short side is longer due to adjustment of the sliding fitting part.SELECTED DRAWING: Figure 1 【課題】従来よりも軽量かつ強度の高い足場板を提供する。【解決手段】足場板１は、長辺方向に延在する５個のアルミニウム製の中空形材が短辺方向に配列して互いに嵌合され、板状に形成されている。これらの中空形材は、短辺方向の中央に位置する中央材１１と、この中央材１１の両側に位置する中間材１２，１３と、短辺方向の一端に位置する第１端材１４と、短辺方向の他端に位置する第２端材１５で構成されている。中央材１１と中間材１２，１３との間の嵌合部分と、中間材１２，１３と第１端材１４及び第２端材１５との間の嵌合部分は、互いの部材が嵌合した状態で幅方向に摺動可能に形成された摺動嵌合部となっている。足場板１は、摺動嵌合部の調整により、一方の短辺が短く、他方の短辺が長い扇形に形成することができる。【選択図】図１
