    摘要: An anchor on a tendon twisted of a number of steel wires has at least one double-cone widening, the biggest diameter of which is at least three times bigger than the diameter of the unfanned tendon part. The method for producing the anchor comprises seizing the tendon on two spaced apart places and bulging it between these places to form a widening. On the frame of the device for carrying out the above method there are provided two means for seizing the tendon on two places spaced apart whereby one of the means is actuated to exert an axial load on the tendon.

    摘要: An apparatus for anchoring a ring tensioning member in a circular container, especially a concrete tank or a concrete tube, characterized by a hemispherical anchorage body being located in a recess in the wall thickness of the container in overhung position having on its circumference at least one slot and through bores for a bracing cable. The bracing cable which has been inserted in the wall of said container and prestressed by a stretching mechanism will be anchored in said anchorage body, whereafter the recess will be covered in such a way as to be in alignment with the surface of said container.

    摘要: A preserving element (5) formed as a synthetic material mould part has preserving troughs (6) in which the bent end sections (3b) of connecting bars (3), later to be bent out, are embedded with a brittle mass (7). The device has the advantage that after the anchoring of the connecting bars (at 3a) in the structural member (2), the element (5) and the mass (7) can be easily removed. The device forms an easily transported and handled structural unit which is usable in the production of construction joints of steel concrete structures of any kind.

    摘要: A method for anchoring a ring tensioning member in a circular container, especially a concrete tank or a concrete tube is characterized by cutting out at least one recess in the wall thickness of said container for locating therein a hemispherical anchorage body in overhung position having on its circumference at least one slot and through bores for a bracing cable. The bracing cable which has been inserted in the wall of said container and prestressed by a stretching mechanism will be anchored in said anchorage body, whereafter the recess will be covered in such a way as to be in alignment with the surface of said container.
