VOID FORMWORK, PANEL WITH VOID FORMWORK, AND CONCRETE SLAB
To reliably suppress a resonance phenomenon occurring on the surface of a void formwork.SOLUTION: A void formwork 10 includes a corrugated portion 11 and a rectangular portion 12, embedded in a concrete slab, and having unevenness on an upper surface 13 side. When one of the directions perpendicular to a vertical direction (z-axis direction) that is the thickness direction of the void formwork 10 is a width direction (x-axis direction), and the direction perpendicular to both the thickness direction and the width direction is a length direction ( y-axis direction), the unevenness has a shape in which a width direction waveform z(x) extending in the width direction of the void formwork and a length direction waveform (y) extending in the length direction overlap.SELECTED DRAWING: Figure 1
【課題】ボイド型枠の表面で生じていた共振現象を確実に抑制することを目的とする。【解決手段】波型部分１１と矩形部分１２とを備え、コンクリートスラブ内に埋設される、上面１３側に凹凸を有するボイド型枠１０において、ボイド型枠１０の厚さ方向である上下方向（ｚ軸方向）に垂直な方向の一つを幅方向(ｘ軸方向)、厚さ方向と幅方向の両方に垂直な方向を長さ方向（ｙ軸方向）としたとき、前記凹凸を、ボイド型枠の幅方向に延長する幅方向波形ｚ（ｘ）と長さ方向に延長する長さ方向波形（ｙ）とを重ねた形状とした。【選択図】図１
