Abstract: A method of constructing a poured concrete structure protected from corrosive agents includes applying large-surface sealing elements to one surface of the structure before pouring the concrete. The sealing elements are attached to anchoring elements extending into a region into which concrete is to be poured. When the concrete is poured inside the sealing elements, the sealing elements are anchored in place by the anchoring elements which become set in the concrete. The sealing elements may have a high modulus of elasticity and be relatively rigidly affixed to the structure of may have a low modulus of elasticity and thus require overlapping perimeter areas for sealing of adjacent sealing elements.

The body (1) is designed for releasable fastening to the shuttering for the structural member that is to be cast first of all. In this respect, the half, averted from the shuttering, of the threaded hole serves to receive an end, provided with an external thread, of a reinforcing part (9) that is to be embedded into the structural member that is to be cast first of all, and the other half of the threaded hole serves, after removal of the shuttering, to receive an end, provided with an external thread, of a reinforcing part (11) that is to be embedded into the structural member that is to be cast after that.

Abstract: Before a main wall is prepared by pouring concrete, a profile element with anchor steel rods extended through its bottoms is fitted to a planking in such a way that a cavity is created between the bottoms of the profile element and the planking. The profile element has two side walls and two bottoms lying in the same plane. The anchor steel rods extended through the bottoms form U-shaped loops on the one side of the element, whereas the end portions of the anchor steel rods bent in right angles from the legs of the U-shaped portions lie on the other side of the element. The surface of the profile element is roughened and its side walls enclose each a sharp angle with the bottoms. By means of the profile element locked in the concrete of the completed main wall a groove is formed in the outer face of the concrete main wall out of which groove the end portions of the anchor steel rods can be bent outward without additional works, such as scratching-out of a plastic body as per the prior art.

Abstract: A low cost, structurally superior bridge and fabrication method are described which take maximum advantage of the compressive strength of concrete, and the tensile strength of steel, to give a bridge structure having the lowest allowable depth-to-span ratio and good dead load/live load ratios, as well as minimum deflection under impacting, moving concentrated loads. The bridge is most preferably shop cast in sections which include lowermost, substantially planar structural metallic plates (e.g., 5/16" thick self-rusting steel) of length and width dimensions substantially equal to that of the sections; a separate layer of concrete is then composited to each plate, preferably by means of upstanding studs secured to the plate and embedded within the concrete. Monolithic bridge sections are thus formed which can be transported to the bridge site, erected and connected, typically by welding the respective section plates together at regular intervals.

Abstract: A method for the manufacture of reinforcement members, in which steel rods are first bent into a U shape and the two arms of the U-shaped piece are then bent off at right angle, at a particular distance from the cross bar of the U. These steel rods are placed at preselected intervals of the U-shaped portion and with their bent-off arms lowermost, into a trough-shaped basin with outward sloping side walls. A liquid foam material is then brought into the basin so that the preshaped reinforcing rods will be immersed with their bent-off arms in the solidified foam material, while the brackets project with their cross bar from the foam material.
