    摘要： Complex, three-dimensional, variable section casts with a high level of dimensional control can be made from molds consisting of two flat or tailored sheets of flexible material (such as fabric) held between rigid clamps. The clamping materials control the shape and dimension of the mold in the X and Y directions while the flexible sheets are allowed to deflect in the Z direction. Void shapes in the truss can be obtained when the clamping material presses the two sheets together.

    摘要： A device for use in casting concrete piles in a mold consisting of a bottom section and two side walls. The piles are formed with lengthwise reinforcement rods, on the ends of which are attached interconnecting members passing through the end fittings of the pile. The device is characterized by an alignment member arranged to be positioned in the mold. Abutment faces on the alignment member are arranged in engagement with the side walls and the bottom section of the mold at right angles to the longitudinal extension thereof. The alignment member is provided with shoulders forming points of abutment for engagement with the ends of the interconnecting members. A pulling means is arranged to engage in the center of said end fitting members and with the aid of a support means provided in said alignment member to urge the ends of the interconnecting members into abutment against the shoulders of the alignment member, when said tightening means is tightened. The device facilitates alignment of the end fitting members in an exactly right-angled position to the longitudinal direction of the mold and ensures that the aligned relationship is maintained throughout the entire casting operation.

    摘要： A process for producing reinforced concrete building units such as concrete floor panels having coffer-like inner holes with smooth upper and lower surfaces, comprises providing a layer of reinforced concrete on the lower edges of a building unit comprised by an upper panel and joining ribs intersecting each other. A reinforcing steel mat is secured to the lower edges of the ribs which is then immersed in a layer of concrete resting on a plate. The assembly is vibrated to consolidate the concrete around the mat and after hardening, the plate is removed, leaving a smooth undersurface on the resulting hollow construction. The panel can be prestressed to a downwardly convex shape, in which case the plate is given a corresponding upwardly concave curvature.

    摘要： The present invention relates to a method and apparatus for fabricating a reinforced concrete cylinder, and more specifically to a method for centering a reinforcing frame within a form used during the placement of a concrete slurry. One embodiment of the present invention includes a plurality of centering arms that are adapted for selective engagement with the reinforcing frame, thus maintaining it in the predetermined radial location during the fabrication process.
