LEDGER FRAME WITH FLOOR
To provide a ledger frame with a floor eliminating a gap formed between a horizontal member and a beam member and capable of suppressing the falling-down deformation without providing a new reinforcement member even when an unexpected impact load is applied to a gripping metal fitting.SOLUTION: A ledger frame with a floor comprises a floor plate member 1, a cloth member 2, a beam member 3, and a gripping metal fitting. The beam member 3 comprises: an upper side flange 3a whose rear end portion is fixed to the floor plate member 1 and whose tip portion extends toward the outside of the floor plate member 1; a lower side flange 3b fixed to a terminal flange portion 1b of a leg portion 1a provided in the floor plate member 1; and a web 3c having a Y-shaped cross section connected respectively with at least two places of the upper side flange 3a and a tip portion of the lower side flange 3b.SELECTED DRAWING: Figure 7
【課題】横架材とはり材との間に形成される隙間をなくすとともに、つかみ金具に予期しない衝撃荷重が作用したとしても、新たに補強部材を設けることなしにその倒れ込み変形を抑制することができる床付き布わくの提案。【解決手段】床板材１と、布材２と、はり材３と、つかみ金具とを備えた床付き布わくにおいて、はり材３は、後端部が床板材１に固定され、先端部が床板材１の外方へ向けて延出する上側フランジ３ａと、床板材１に設けられた脚部１ａの末端フランジ部１ｂに固定される下側フランジ３ｂと、上側フランジ３ａの少なくとも２箇所および下側フランジ３ｂの先端部にそれぞれつながるＹ字状断面をなすウエブ３ｃからなる。【選択図】図７
