CONSTRUCTION METHOD OF SOUND INSULATION FLOOR STRUCTURE, SOUND INSULATION FLOOR STRUCTURE, FLOOR PANEL BODY, AND BUILDING WITH SOUND INSULATION FLOOR STRUCTURE
PROBLEM TO BE SOLVED: To improve a heavy impact sound insulation performance of a floor structure, while preventing workability degradation of the floor structure.SOLUTION: An example of this invention is a construction method of a sound insulation floor structure 1, in which an additional beam 3 separating a prescribed span S1 into two separated spans S2 with a same beam interval is placed between main beams 2A, 2B placed parallel to each other across the prescribed span S1, and a floor panel body 4 is placed with the separated span S2. This construction method comprises following processes: making use of a beam interval to calculate a natural frequency of a panel body part 6 included in the floor panel body 4; installing stiffener parts 7a, 7b which cooperate with the panel body par 6 to define a cross-sectional property of the floor panel body 4 when the natural frequency is equal to a lower limit natural frequency or higher, on an undersurface 6a and an uppersurface 6b of the panel body part 6.
【課題】床構造の施工性の劣化を抑制しつつ、床構造の重量衝撃音の遮断性能を向上させる。【解決手段】本発明の一例は、所定スパンＳ１をもって互いに平行に配置された主梁２Ａ，２Ｂ間に、所定スパンＳ１を互いに等しい梁間隔の分割スパンＳ２に分割する追加梁３が配置され、分割スパンＳ２を跨いで床パネル体４が配置された遮音床構造１の施工方法である。この施工方法は、梁間隔を利用して、床パネル体４に含まれたパネル本体部６の固有振動数を算出する工程と、固有振動数が下限固有振動数以上である場合に、パネル本体部６と協働して床パネル体４の断面性能を規定する補剛部７ａ，７ｂをパネル本体部６の下面６ａに設ける工程と、を有する。【選択図】図１
