CONCRETE COMPACTION EFFECTIVE RANGE EVALUATION METHOD
PROBLEM TO BE SOLVED: To provide a concrete compaction effective range evaluation method which specifies the outside of a compaction effective range from a concrete compaction effective range by grasping an insertable/withdrawal range of a vibrator in advance prior to the arrangement of reinforcing bars by using a three-dimensional CAD figure, and can contribute to the review of a reinforcing bar arrangement schedule or the like upon necessity.SOLUTION: In a concrete compaction effective range evaluation method, a three-dimensional CAD figure A is created from a reinforcing bar arrangement figure by using a CAD system on a personal computer, an arrangement of a concrete vibrator is decided by laminating a plurality of pieces of vibration parts 1 to/from which a concrete vibrator can be inserted and withdrawn in a space between reinforcing bars in a plane view of the CAD figure A, and a range of the outside of the effective range 3 is specified by making a center of a compaction effective range circle 2 corresponding to a compaction capacity of the concrete vibrator coincide with and overlapped on a center of the vibration part 1 to/from which the concrete vibrator can be inserted and withdrawn.SELECTED DRAWING: Figure 1
【課題】３次元ＣＡＤ図面を利用して、配筋を組む前に、予めバイブレータの挿入出可能範囲を把握することで、コンクリートの締固め有効範囲から、締固め有効範囲外を特定し、必要に応じて配筋計画等の見直しに役立てることができるコンクリート締固め有効範囲評価法を提供すること。【解決手段】パーソナルコンピュータ上でのＣＡＤシステムを利用して、配筋図面から３次元ＣＡＤ図面Ａを作成し、ＣＡＤ図面Ａの平面視鉄筋のあきにコンクリートバイブレータの挿入出可能な振動部１を複数重ねることで該コンクリートバイブレータの配置を決定し、各挿入出可能な振動部１の中心に前記各コンクリートバイブレータの締固め能力に応じた締固め有効範囲円２の中心を合わせるように重ねることで該有効範囲外３の範囲を特定することを特徴とするコンクリート締固め有効範囲評価法。【選択図】図１
