Abstract: The invention relates to a form for producing concrete rails for rubber-tired vehicles which are guided on a track. In contrast to steel rails, concrete rails no longer bend after production, so that numerous different molds are required for curves, transition curves, super elevations, and the like. This drawback is avoided with the form according to the invention, wherein the form makes it possible to produce both straight rail sections, as well as rail sections having varying curvatures, using the same mold. As a result, the expenditure for rail forms is considerably reduced.

Abstract: The invention is directed to a recessible guide rail for guiding a wheel-supported vehicle along a roadway structure. The vehicle is equipped with flangeless wheels or the like for coacting with a side wall of the rail to laterally guide the vehicle along the roadway structure. It is necessary to remove the guide rail from time to time in order to realize the advantages of such a vehicle on its special rail-like roadway structure and on conventional roads. With the guide rail removed, it is possible to remove the laterally guided vehicle from its roadway structure. Also, it is possible to permit other vehicles to cross the special roadway structure of the guided vehicle. With the invention, supporting devices having lateral holding pockets which can be moved in elevation are installed where the guide rail is to be removable. Straight or curved guide rail segments which can be made of steel reinforced concrete are inserted into the pockets.

Abstract: A method of and arrangement for correcting the height of a railway upper structure with a reinforced concrete plate thereon into which plate a reinforced concrete part as support for rail holding members is so inserted that the reinforced concrete part is positioned above a just finished or poured concrete section of the reinforced concrete plate in conformity with its end position and is subsequently lowered and jarred into the not yet hardened concrete of the reinforced concrete plate.

Abstract: A space framework for building up dismountable ceilings and walls which comprises pyramid-shaped elements each including reinforced concrete slabs with corners connected to steel profiles which are adapted to be subjected to tensile and pressure forces and come together at a joint. The pyramid-shaped elements are at the corners of the pertaining reinforced concrete slabs put together by means of connecting elements to form a space confining surface adapted in its plane to take up pressure forces. The joints at the tips of the respective pyramids are connected to tension members extending substantially parallel to the reinforced concrete slabs.

Abstract: An anchoring arrangement, especially for pre-stressed concrete constructions, for anchoring reinforcing means in the form of ropes, cables, wires and rods, by means of a sleeve and an intermediate layer arranged within the sleeve and defining an axially extending hollow space substantially filled by the reinforcing means to be anchored. The intermediate layer which tightly engages the sleeve and the reinforcing means comprises granular material and a binding substance therefor, while the intermediate layer is harder than the reinforcing means.
