TREADBOARD OF STEEL STAIRCASE AND STEEL STAIRCASE HAVING THE SAME
PROBLEM TO BE SOLVED: To provide a treadboard of a steel staircase filled with an inorganic filler which can ensure high quietness and load strength at low cost while easily created without causing deformation of the treadboard.SOLUTION: A treadboard 1 of a steel staircase is formed by filling a cavity 10 of a treadboard body 2 made of steel plate, in which a cavity 10 is formed inside while surrounded by a bottom face plate 3a, a front face plate 3b, a rear face plate 3c and a treadboard plate 4, with an inorganic filler, and solidifying the inorganic filler. In the treadboard body 2, at least one girder member 6 arranged in a major axis direction so as to partition a range occupying the most of the major axis direction in the space by a predetermined position in the minor axis direction is provided in the cavity 10, and the girder member 6 is fixed to the bottom face plate 3a and the treadboard plate 4 in a predetermined portion, and the bottom face plate 3a and the treadboard plate 4 are integrated with each other through the girder member 6.SELECTED DRAWING: Figure 2
【課題】内部に無機質充填剤を充填した鋼製階段の踏板について、踏面の変形を伴うことなく容易に作成可能なものとしながら、低コストで高い静音性と荷重強度を確保できるようにする。【解決手段】底面板３ａ・前面板３ｂ・後面板３ｃ・踏面板４で囲みながら内部に空洞１０を形成した鋼板製の踏板本体２の空洞１０に無機質充填剤を充填・固化してなる鋼製階段の踏板１であって、その踏板本体２は、空洞内１０にその空間のうち長径方向の大部分を占める範囲を短径方向の所定位置で仕切るように長径方向に配置された少なくとも１本の桁部材６を備えており、その桁部材６が底面板３ａと踏面板４に所定箇所で固定されて底面板３ａと踏面板４が桁部材６を介し一体化されていることを特徴とするものとした。【選択図】図２
