method of producing a montagebauteils for self-supporting dachtafeln or paving

摘要

A process for the preparation of a mounting member made of porous concrete for the production of a self-supporting roof panel or wall panel, comprising a mineral, with at least one, at least one lower chord element (10, 11), at least one upper chord element (14), as well as at least one web element (12, 13) between the lattice girder (9) having a reinforced plate element, on which a heat insulation element in the form of layers is arranged, the lower chord element of the reinforcement carrier is embedded in the plate element and the web element of the reinforcement carrier passes through the plate element and the heat insulation element, according to the per se known pores concrete technology, wherein a water-containing, pourable, hydro thermal consolidated calciumsilikathydratphasen simultaneously end, that is formed into a distiller''s wash is fed auftreibbare having a hardness bottom, trough-like pores concrete the form of cast, area and to a pores concrete cake is allowed to time, then the stiffened pores concrete cake is acted upon in an autoclave hydrothermally, so that, as a result of calcium silicate hydrate phases formation is solidified, and then removed and the autoclave is cooled,characterized in thata) the lattice girder (9) into the pores of concrete are provided in the form of,b) the pores concrete shape and the lattice girder (9) to temperatures between 40..
