The invention relates to storage containers for liquids with horizontally lying bottom and Cover plate and with these connected, outwardly curved side walls, on their outer surfaces vertical stiffeners are attached. The walls run between the corner connections in known way in a continuous arc. The stiffeners are around a third of the half Side wall lengths attached away from the corner joints. These stiffeners allow storage containers with curved side walls can also be made for very large content, with the advantage what is achieved is that the inside of the container is free of disruptive supports and struts that would otherwise when applying corrosion protection, when walking on the containers and when cleaning them in Ways are.

So far, storage containers for liquids were mostly used as cylindrical containers or as containers with made flat walls. The cylindrical ao containers can only be delivered to the installation site as prefabricated containers are brought, whereby there are limits to their size. The cuboid Containers with flat walls require complex and intricate reinforcements inside the container are to be attached and therefore when cleaning and attaching interior linings interfere with corrosion protection and make the containers more difficult to walk on. - So it was fine proposed containers in a lying or standing design with a flat bottom and top plate as well run between these arranged bowl-shaped arched panels, in which in the corners of the Container additional stiffeners are arranged. In addition, they are arched from several Panels composed of walls, the channel-shaped depressions between the panels with in Provided longitudinally arranged stiffening ribs. - In another known container design The walls run between the corner connections with a flat floor and ceiling plate in a continuous arc. Here, however, prepare the strength calculations, especially for the corner connections, difficulties so that the. There are limits to the size of such containers.

According to the invention, storage containers with curved Scitenwäiiden on the outer surfaces vertical stiffeners attached to the side walls. These stiffeners that are inside the about the Seitenwändc protruding outer edges of the floor and ceiling panels are with these as well as welded to the walls.

wise are the stiffeners in the vicinity of the corner connections, but at least so that they are about attached at a third of the half length of the side wall from the corner joints of the side walls are. As a result, an effective support of the corner connections is achieved, and the from Forces resulting from the internal pressure of the container are absorbed by the stiffeners. With very Large containers can also have several stiffeners next to each other be attached. - A further improvement can be made to storage containers with curved side walls can be achieved with regard to the detection of the balance of forces that as corner connections the side walls rounded spacers are provided and attached by inside and outside Welds are connected to the side walls.

Both the external reinforcements of the side walls and the rounded design of the corners leave the inside of the tank free of disruptive installations, so that a perfect lining as corrosion protection, easy cleaning and easy access to the inside of the container are.

In the drawing, an embodiment of the invention is shown, namely shows

1 shows a storage container in side view,

FIG. 2 shows a cross section of the storage container along the line AB in FIG. 1 and

Fig. 3 and 4 different possibilities of Design of the corner connections,

The storage container has horizontally lying floor and ceiling panels 3, 4, with which the vertical, outwardly curved side walls 1, 2 are connected. The curvature of the side wall ^ 1, 2 gclit evenly on both sides from the center CD or from the center /.'-/· ', and the corner edges butt

vertically together. In support of the Eek connections are near the outside of the side walls 1, 2 stiffeners 7, 8 attached, the inside the contour edges of the floor and ceiling panels 3, 4 lie and with these and with the walls 1,2 are welded.

The stiffeners 7, 8 preferably have a T-shaped cross section, and the central webs lie against the outer surfaces of the side walls. The position of the stiffeners 7, 8 in relation to the corner connections is about such that it is one-third the length of the side wall from the eek joints remotely attached.

On the right side of the storage container shown in Fig. 2 meet the vertical side edges of the Walls 2 against the slightly protruding ends of the walls 1 and are through internal and external Welds connected. On the left of the FIG. 2 and in FIGS. 3 and 4 are examples of one preferred corner connection shown. The corners are formed by rounded spacers 9 or 10 formed, which are inserted between the side walls 1, 2 or placed on them and through Welds 11, 12 are connected to these. The rounded spacers 10 can inside or placed on the outside of walls 1, 2:

The rounded spacers 9 and 10 result in a better "calculation basis for the Eek connections, but especially with larger containers for safety reasons, the Stiffeners 7, 8 are not superfluous, but provide a further guarantee for the proper construction the storage container. In the context of the invention, it is also possible, instead of the intermediate pieces 9 or 10 Insert closed pipes as corner connections and weld them to the side walls 1, 2.

The interior of the container, e.g. B. is accessible via a manhole 6, can through the smooth walls can be provided with corrosion protection without difficulty. - The invention Storage container is particularly suitable as a basement tank for heating oil that is in place can be assembled.
