    • PROBLEM TO BE SOLVED: To provide a floor slab which can improve performance of insulating floor impact sound downstairs and is easy in construction.SOLUTION: A floor slab 1 comprises: a flat plate part 7; and projections 6 projecting from the upper surface 4 or lower surface 5 of the flat plate part 7 or from the upper and lower surfaces 4, 5 thereof, and the projections 6 are not directly connected to a beam. The projections 6 are installed so as to project from the upper surface 4 or lower surface 5 of the flat plate part 7 located below a corridor area 3 of a dwelling unit. The flat plate part 7 is designed to have a characteristic frequency capable of obtaining desired performance of insulating floor impact sound downstairs from a habitable room 8, and a ratio of the total weight of the projections 6 to the total weight of the floor slab 1 is determined so that a characteristic frequency of the floor slab 1 with the projections 6 is within a range capable of obtaining the desired performance of insulating floor impact sound downstairs from the habitable room 8.
    • 要解决的问题:提供一种能够提高楼下的绝缘地板撞击声的性能的楼板,并且容易施工。解决方案:地板1包括:平板部分7; 并且从平板部7的上表面4或下表面5突出的凸起6或其上表面4,5的下表面和凸起6不直接连接到梁上。 突起6安装成从位于住宅单元的走廊区域3下方的平板部7的上表面4或下表面5突出。 平板部7被设计成具有能够从居住室8获得楼下的绝缘地板撞击声的期望性能的特征频率,并且突起6的总重量与楼板1的总重量的比率为 使得具有突起6的地板坯1的特征频率在能够从可居住的房间8获得楼下的绝缘地板撞击声的期望性能的范围内。

    • PROBLEM TO BE SOLVED: To provide a double floor which is low in cost and can maintain the same strength of a substrate in comparison with a structure in which the whole of upper and lower substrate plate layers composing a substrate is formed with a structural plywood.SOLUTION: A double floor 1 includes a floor slab 2, support legs 3 with a rubber vibration isolator 31 disposed on the floor slab 2 at predetermined intervals, and a floor board constituting part 4 formed on the support legs 3. The floor board constituting part 4 includes a base material 40 formed on the support legs 3, a substrate 50 formed on the base material 40, and a floor finish part 60 formed on the substrate 50. The substrate 50 includes a lower substrate plate layer 51 formed by horizontally arranging a plurality of plates on the base material 40, and an upper substrate plate layer 51 formed by horizontally arranging a plurality of plates on the lower substrate plate layer 51. At least one of the upper and lower substrate plate layers 51, 52 is formed of plates other than plywood.
