GRATING AND PRODUCTION METHOD OF GRATING
To provide a grating and a production method of the grating, wherein the grating has a good balance of the various characteristics of weight, component strength and component stiffness.SOLUTION: A grating 1 comprises a plurality of bearing bars 10 and a plurality of connecting members. The plurality of bearing bars 10 comprises: a vertical plate part 10A that is made of a high-strength steel plate having a yield stress of 295 MPa or more and extends in a vertical direction; a bending part 10K that is connected to an upper end part of the vertical plate part 10A; and a load receiving part 10B that has at least a portion extending in a direction crossing a vertical direction, is connected to the vertical plate part 10A via the bending part 10K, constitutes a part of an upper surface part, and can receive a load acting from above.SELECTED DRAWING: Figure 2
【課題】重量、部品強度および部品剛性の各特性のバランスに優れたグレーチングおよびグレーチングの製造方法を提供する。【解決手段】グレーチング１は、複数のベアリングバー１０と、複数の接続部材とを備える。複数のベアリングバー１０は、降伏応力２９５ＭＰａ以上の高強度鋼板からなり、上下方向に延びる縦板部１０Ａと、前記縦板部１０Ａの上端部に接続される曲げ部１０Ｋと、少なくとも上下方向と交差する方向に延びる部分を有し曲げ部１０Ｋを介して縦板部１０Ａに接続される荷重受け部であって、前記上面部の一部を構成し上方から作用する荷重を受けることが可能な荷重受け部１０Ｂとを含む。【選択図】図２
