Abstract: The joining and welding profile (3) for producing a storage container (1) consisting of cylindrical container sections (2, 2') serially arranged one after another, comprises a cylinder ring, and a cone ring connecting itself to the cylinder ring. The cylinder ring and the cone ring are connected by using a welding seam. The cylinder ring is fastened to the outer sheath of two adjacent container sections and axially extends between the adjacent container sections, so that a radially inwardly pointing annular groove lies in the cylinder ring in the area of its oppositely-lying front sides. The joining and welding profile (3) for producing a storage container (1) consisting of cylindrical container sections (2, 2') serially arranged one after another, comprises a cylinder ring, and a cone ring connecting itself to the cylinder ring. The cylinder ring and the cone ring are connected by using a welding seam. The cylinder ring is fastened to the outer sheath of two adjacent container sections and axially extends between the adjacent container sections, so that a radially inwardly pointing annular groove lies in the cylinder ring in the area of its oppositely-lying front sides of the ends of the adjacent container sections. The cone ring opens away from radially inside to radially outside from the container section with the cylinder ring fastened to it towards the adjacent container section, and completely lies on the side of the container section, which is opposite to the container section with the cylinder ring fastened to it. The cylinder ring is detachably frictionally or positively fixed at the outer sheath surface of the container section by using a clamping device. The annular groove is engraved as bead by roller radially outside at the welding seam and/or its welding seam root between the opposite front sides of the ends of the two adjacent container section. The clamping device represents a steel cable shortenable by a knee lever in its acting length. The cylinder ring and the cone ring are opened and a gap is formed between the both ends, where the gap is reducible by the clamping device. A flat guide is arranged between the both ends and always holds the ends axially at same height. A rupture safeguard is arranged between the ends and always secures the ends to each other, so that a maximum gap is not exceeded. The joining and welding profile is formed in one-piece made of non-alloyed construction steel plate, alloyed stainless steel plate or aluminum with a plate thickness of 5-10 mm, and the annular groove is engraved as bead by roller radially outside at the welding seam and/or its welding seam root between the opposite front sides of the ends of the two adjacent container section and is incorporated radially outside at the welding seam and/or its welding seam root of its oppositely-lying front sides of the ends of the two adjacent container section by machine cutting treatment e.g. milling. Three longitudinally-adjustable spacing bars that are evenly distributed over the circumference of the joining and welding profile are arranged at the cylinder ring. The spacing bars are fixed to the cylinder ring with its one end and supports at the ground or an assembly ring (9) with its other end, so that the profile is axially secured to the outer sheath of the container section. The spacing bars are changeable in their lengths by bolt connection, positive latching connection or hydraulic and/or pneumatic cylinder piston construction. An independent claim is included for a method for constructing a storage container consisting of cylindrical container sections serially arranged one after another.
