  • Patent number: 4497153
    Abstract: Proposed is a method for the erection of structures, such as bridges, that display pre-fabricated concrete beams, according to which the individual pre-fabricated beams are produced, on the spot, on a feed rigging within the corresponding work area of the structure, in a heated and laterally tiltable form. After removal from the form, the thusly produced pre-fabricated beams are transferred sidewardly into their final position by means of gantry cranes. During concretizing of the individual pre-fabricated beams, flexure of the feed rigging carrying the form is equalized in continuous fashion, in correspondence with the progressing, concretizing process, by transfer pumping of ballast liquid.

  • Patent number: 4468906
    Abstract: The dimensions of the blocks or bricks are, first, derived from the side lengths a, b of the tiles and, second, from the thickness d of the corner tiles, whereby an amount (a/2)-d, or (b/2)-d is obtained for the wall thickness of the blocks. The two-shell structure as well as the usual staggered arrangement by half the tile length provides a sequence of blocks of the following lengths: (a/2)-d, a/2, a-d, a, (3a/2)-d, 3a/2, 2a-d, 2a, etc. A further sequence of blocks of the following heights is obtained: (b/2)-d, b/2, b-d, b, (3b/2)-d, 3b/2, 2b-d, 2b, etc. Further sequences in respect of height and length are obtained from the two basic sequences, each smallest member being a member of a basic sequence. In a preferred embodiment, the tiles have a square visible face and the thickness a/4. Hence, the blocks have the same wall thickness and the length and heights a/4, a/2, 3a/4, a, 5a/4, 3a/2, 7a/4, 2a, etc.
