    摘要： Pin point foundations are formed, the ground is flattened and levelled at the level of these foundations, peripheral recoverable shuttering is disposed on the ground and continuous rows of non recoverable shuttering defining the ribs are disposed at the center. The rows of shuttering are spaced apart by baryte cardboard elements providing sealing and insulation. On the upper face of the non recoverable shuttering are disposed means for spacing the trellis work reinforcing the floor. Then the concrete is poured by pumping and, after drying out the floor, only the peripheral shuttering is recovered.

    摘要： This disclosure relates to a floor construction comprising a concrete slab which is supported adjacent its edges of the slab. A plurality of cellular raceways are embedded in the slab, and at least one intermittently bottomless trench runs across the raceways. The trench is located along a line where the bending moment on the slab is substantially zero. The construction further comprises a plurality of post-tensioned tendons which extend across the slab, underneath the trench and between the raceways.

    摘要： This specification relates to apparatus and method for improving construction joints in reinforced concrete structures. A coupling member extends a short distance beyond the joint between two pours and has edges which mechanically couple to joining or adaptor members on the ends of reinforcing bars.

    摘要： A steel joist formwork and a composite steel and concrete floor structure provided with a top chord, a bottom chord and a web joining the top and bottom chords with the top chord being serpentine shaped like an S or Z and including top and bottom, generally horizontal portions and an intermediate portion integrally connecting opposite edges of the top and bottom portions with the top and intermediate portions substantially being adapted to be embedded in the concrete floor to cause the floor and steel joists to act structurally as a composite beam. Either the web or a leg depends vertically from the free end of the bottom portion of the top chord, and the web joining the top and bottom chords is substantially solid or is, an open web formed of a zig-zag bar member. There is also disclosed a building system and erecting method utilizing steel joists spaced apart by spanner bars which also support rigid panels which act as formwork for the pouring of concrete. The spanner bars and the joists are so arranged to cooperate that the spanner bars may be removed together with the rigid panels after the concrete has been poured, and the spanner bars, the rigid panels and if desired the steel joists may be reused for formwork for additional poured concrete construction. Alternatively the joists may be left in place either with the top chords embedded in the poured concrete to provide a composite action, or merely supporting the concrete slab in the conventional fashion. A novel cold rolled sheet steel joist may be advantageously used to form a particularly economical composite system. This steel joist is shaped in an I-beam configuration with an upper top chord bent to have the appearance of the letter Z in cross-section for bonding with the concrete floor.

    摘要翻译： 钢托梁模板和复合钢筋混凝土地板结构，其具有顶弦，底弦和连接顶弦和弦杆的腹板，顶弦与S或Z形成蛇形，并包括顶和底，大致水平 部分和中间部分整体连接顶部和底部的相对边缘，顶部和中间部分基本上适于嵌入在混凝土地板中，以使地板和钢托梁在结构上作为复合梁起作用。 腹板或腿部从顶弦的底部的自由端垂直地取向，并且连接顶部和底部弦杆的腹板基本上是固体的，或者是由之字形杆构件形成的开放腹板。 还公开了一种建筑系统和竖立方法，其利用由扳手杆间隔开的钢托梁，其还支撑用作浇注混凝土的模板的刚性板。 扳手杆和托梁被布置成配合，以便在浇筑混凝土之后，扳手杆可以与刚性板一起被移除，并且扳手杆，刚性面板以及如果需要，钢托梁可以重新用于模板 额外浇筑混凝土施工。 或者，可以将托梁放置在适当位置，将顶部和弦嵌入浇注的混凝土中以提供复合作用，或仅以常规方式支撑混凝土板。 一种新颖的冷轧钢板托梁可以有利地用于形成特别经济的复合系统。 这种钢托梁成形为I型梁结构，上顶部弦杆弯曲成具有字母Z的外观，横截面用于与混凝土地板接合。
