Abstract: The composite wall element comprises linear or curved plate segments made of mineral cast with integrated armor and with a piping system (4) for transmitting a liquid or gaseous heat distribution medium or a cooling agent. A reinforcement grating is inserted in a gap between the plates and an intermediate gap is poured with a filling mass. An inner wall (1) of the composite wall element is equipped with the piping system for the heat distribution medium or the cooling agent. An outer wall (2) of the composite wall element is positioned with a distance to the inner wall. The composite wall element comprises linear or curved plate segments made of mineral cast with integrated armor and with a piping system (4) for transmitting a liquid or gaseous heat distribution medium or a cooling agent. A reinforcement grating is inserted in a gap between the plates and an intermediate gap is poured with a filling mass. An inner wall (1) of the composite wall element is equipped with the piping system for the heat distribution medium or the cooling agent. An outer wall (2) of the composite wall element is positioned with a distance to the inner wall. A heat insulator (7) is arranged on the inner side of the inner wall and the free surfaces in the intermediate gap are structured. The reinforcement grating is displaced and integrated against the plate joints between the composite wall elements in an overlapping manner. A tie rod is inserted parallel to the bridging struts and stiffening strips are mounted on the inner side of the outer wall. The anchorage of the composite wall element is carried out on a base plate by a supporting pillar, which is fitted in the intermediate gas of the composite wall element and is anchored below the base plate. The bridging struts consist of reinforced mineral cast, and are adhesively welded and/or bolted in a positive and non-positive manner. Profile struts made of metal and glass fiber reinforced plastic are provided as the bridging struts, and are stuck together and/or screwed with the inner and outer walls in a positive and non-positive manner. The bores of the tie rod are concisely locked with mineral cast filler. The stiffening strips consist of mineral cast, metal or glass fiber reinforced plastic, and are adhesively welded or screwed with the outer wall. The heat insulator is pressure-resistant and the heat insulating material consists of igneous rocks, pumice stone, tuff stone, glass foam body, gas-, light-weight concrete or slag stone. The inner side of the outer wall and the heat insulator is structured with nipples, polygon recesses and/or grooves and bulges. The structure of the free perforated surfaces has a grain size of 10-60 mm. A structural carrier (12) is rolling gravel, broken glass, rough structured cinder or shredded metal or plastic scrap iron, is directly embedded in the mineral cast mass of the outer wall or adhesively welded in a film of polymethmethylacrylate, polyester, epoxide resin or phenyl ester resin fixed with the inner side of the outer wall, and has an undercut against a bearing surface to the halves. The filling mass consists of concrete, lean concrete or concrete mixture. The aggregate consists of cinder granulates, broken glass, shredded rubber from scrap tires, shredded plastic- or scrap metal and/or consumed molding sands. Anchor pins are used for fixing and fastening the reinforcement grating in the inner wall. Individual fields of the reinforcement grating are welded, clampingly screwed, riveted or wired with one another. The connector for the piping system and remaining supply lines and/or control lines are arranged on the container wall top. Tubular channels are arranged in the intermediate gap directly or between the inner wall and the heat insulator for the supply- and/or control lines. The supporting pillar is anchored below the base plate in single foundations.
