    • A method and apparatus for improving the shape of the underside of ribbed concrete slab-on-ground foundations, the foundation having earthen pads and trenched ribs, that includes positioning one or more shoring panels adjacent to at least one of the earthen pads along at least part of one vertical side of a rib, wherein the shoring panels are made from expanded polystyrene treated with a termiticide, backfilling sand in the void between the shoring panels and the earthen pad, dragging a screed across the top portion of the shoring panels to smooth the backfilled sand over the earthen pads, and pouring concrete within a perimeter defined by outer forms and over the earthen pads, backfilled sand, shoring panels, and trenched ribs. The ability to cut and form the panels provides a wide range of structurally efficient cross-sectional shapes with the concrete not possible with traditional methods.
    • 一种用于改进肋肋混凝土板坯地面基础的底面形状的方法和装置,该基础具有土层和沟槽肋,其包括至少沿着至少一个土层定位一个或多个支撑板 肋的一个垂直侧的一部分,其中支撑板由用杀白蚁处理的膨胀聚苯乙烯制成,在支撑板和土垫之间的空隙中的回填砂,将熨平板拖过支撑板的顶部以平滑 在土垫上的填充沙子,以及在由外部形式限定的周界内,并在土垫,回填砂,支撑板和沟槽肋之上浇注混凝土。 切割和形成面板的能力提供了广泛的结构上有效的横截面形状,而混合物不可能采用传统方法。
