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.

Abstract: An upstanding side wall comprises wood plank members having opposite planar outwardly facing vertical surfaces. The longitudinal side edges are bifurcated symmetrically with respect to a vertical central plane bisecting the two planar surfaces. The bifurcations are curved in horizontal cross-section to form a pair of curved tongues with an intermediate concave curved recess between the tongues. Each recess receives a mating tongue of an adjacent vertical plank member. Each member is symmetrical about the central plane and also about a midplane perpendicular to the central plane and midway between the bifurcations. Alternate members may comprise members corresponding substantially to a half of such a member cut along the central plane. A low density soft foam sealant is applied in a groove at the bottom of each recess.
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.
Abstract: An apparatus and method for covering the ridge or peak of a metal roof system is disclosed. After the metal roofing panels are set in place on the sloping surfaces of the roof and seamed together, mating halves of a ridge panel are positioned along the ridge and parallel thereto. The mating halves have cut-outs corresponding to the rib seams of the roofing panels, the cut-outs each being covered by a seam cap. After the ridge panel halves are secured to the roofing panels, the interlocking joint between them is folded over and permanently seamed together. Finally, the areas at the ends of the ridge adjacent the rakes of the building are covered by filler panels. The filler panels have cut-outs corresponding to the rib seam of the ridge panel, and the cut-outs are similarly covered by seam caps.
