COMPOSITE FLOOR SLAB
To provide a deck plate which can constitute a composite floor slab excellent in strength.SOLUTION: A deck plate 2 includes: a substrate 21; a plurality of first reinforcement bars 3 which are arranged so as to be parallel to each other at the same height position on the substrate 21; lattice bars 4A and 4B which show wavy shapes as to oscillate on the same plane with the same amplitude and the same cycle and are arranged so as to face each other in am inclined posture in an opposite direction at both side positions sandwiching the first reinforcement bars 3; and a plurality of second reinforcement bars 5 which are provided so as to be perpendicular to the first reinforcement bars 3 on the plurality of first reinforcement bars 3. Projections 22A and 22B to which bent portions 41 on the lower side of the respective lattice bars 4A and 4B are fixed are formed integrally on the surface of the substrate 21 with such an inclination as to coincide with the inclination of the lattice bars 4A and 4B. The respective bent portions 41 of the lower side of the respective lattice bars 4A and 4B overlap the inner surfaces of the respective projections 22A and 22B and are welded to a position above a bent end. The respective bent portions 40 on the upper side are made to abut on the side faces of the first reinforcement bars 3, and are welded at a position below the bent end.SELECTED DRAWING: Figure 2
【課題】優れた強度の合成床版を構成できるデッキプレートを提供する。【解決手段】デッキプレート２は、基板２１と、基板２１上の同じ高さ位置に互いに平行に配置される複数の第１鉄筋３と、同一平面上を同じ振幅、同じ周期で振動する波形形状を呈し第１鉄筋３を挟む両側位置に逆方向に傾いた姿勢で対向配置されるすラチス筋４Ａ，４Ｂと、複数の第１鉄筋３上に第１鉄筋３と直交して設けられる複数の第２鉄筋５とを備える。基板２１の表面には各ラチス筋４Ａ，４Ｂの下側の屈曲部分４１が固定される突条２２Ａ，２２Ｂがラチス筋４Ａ，４Ｂの傾きと一致する傾きで一体に形成される。各ラチス筋４Ａ，４Ｂの下側の各屈曲部分４１は、各突条２２Ａ，２２Ｂの内面に重ねられて屈曲端より上方の位置で溶接される。上側の各屈曲部分４０は第１鉄筋３の側面に当てられて屈曲端より下方の位置で溶接される。【選択図】図２
