The invention relates to a method for producing the support of a container to be insulated, in particular a cylindrical storage container with a cambered bottom/ opposite a housing,

The object of the invention is to create a particularly solid, load-bearing and well-insulated support for the container through a sensible and purposeful selection and sequence of the process steps, which on the one hand ensures an exact target position of the supports, and on the other hand can be adjusted without any special effort in terms of skill.

According to the invention, at least three supports are first attached to the top of the housing base by means of a push-in screw that passes through the housing base and are connected to one another at the desired distance, then the container is placed on these supports and finally the space remaining between the container and the housing base is filled with insulating material.

If these supports are made of a material that is not or only slightly heat-conductive, such as plastic,

This method not only provides a support that is desirable and solid and stable, but also extremely effective in ensuring the insulation of the container. The supports do not in any way hinder the foaming of the cavity formed between the container and the housing base*, which is to be filled with the insulating material.

In addition, the individual supports, which are connected to one another at a specified distance, can be used advantageously to ensure the container is centered within its housing.

When supporting such containers of the type described above, the problem also arises that supports arranged between the container bottom and the housing bottom tend to move outwards under the high load from the water-filled container, for example, due to the curvature of the container bottom, or are therefore subjected to excessive stress in their connection with the container bottom and tend to tear off.

A further essential feature of the method according to the invention is therefore that the supports, which are distributed centrally symmetrically around the circumference of the container, are connected to one another at a distance via a ring or similar tensile support before the foaming.

Such a ring or similar then serves both as a cover during foaming and as a torsion protection for the housing base, on which or rests snugly.

D 06-Ob-O:

The invention also extends to supports produced by the method according to the invention, and in particular it relates to such a support, the individual supports of which each consist of a pillar-like pressure-transmitting plate and a web adjoining this plate, serving to connect it to the ring, which is directed radially towards the central axis of the container bottom.

This connection creates a solid support for the container, embodied by the individual supports and the common ring, which is particularly suitable for centering the curved base and is characterized, among other things, by the fact that the individual supports do not require a connection to the container base that is difficult to produce, the manufacture of which could also weaken the container base locally.

The components of such a support according to the invention can advantageously be used equally for containers of different diameters; it is only necessary to vary the diameter of the ring connecting the supports and the number of supports (depending on the maximum load).

For the sake of better comprehensibility, numerous other design features of such a support are explained below with reference to the drawings and form the subject matter of the subclaims.

The drawings show an embodiment of a container support according to the invention, namely in

i The container bottom 1 to be supported of a container within a

Housing 2 and surrounded by an insulating layer 3

enclosed cylindrical container, e.g. a hot water tank.

The storage tank rests on (for example) four supports 4 made of non- heat -conducting material, such as plastic, which are distributed peripherally and centrally symmetrically over the circumference of the container base 1 and are detachably connected to one another by a ring 5 also made of non-heat-conducting material. Just like the circumference (diameter) of the ring 5, the number of supports 4 can also be chosen as desired within the scope of the invention and adapted to the respective requirements.

Preferably, the connection of the supports 4 with the ring 5 is positively locked, so that after the support has been made to fit precisely before the foaming with the insulating material 3, the container only needs to be placed on these supports 4 and automatically centers itself. In the embodiment shown, a hook-shaped part 6 of the support 4 overlaps the upper edge of the ring 5.

&Ggr;&igr; :' i I: &igr; \ '"Ii

The lower edge of the ring 5 rests snugly on the housing base 10, so that it serves to protect it against twisting.

Each individual support 4 consists of a pillar-like, pressure-transmitting, for example cross-shaped profiled upright 7 and a web 8 connected to this upright 7, which serves to connect to the ring 5 and is directed radially inwards towards the central container axis and whose free inner end embodies the above-mentioned hook 6 serving to connect to the ring 5.

The free end of this web 8 is also designed as an additional support body 9 and has a vertical threaded hole into which the shaft of a screw 11 serving to fix this support body 9 to the housing base 10 can be screwed.

Furthermore, a web 12 directed radially outwards is attached to the upright 7 of each support 4, which serves to center this support 4 within the housing 2, and a web 13 which is directed inwards and centers the container base 1 within the peripheral supports 4 as soon as it is placed on the supports 4.

Each support 7 has a central threaded hole for the detachable fastening of a foot screw 14 which fixes the support 4 to the housing base 10 and which is itself designed as a height-adjustable base and for adjustment

the position of the container or can be replaced with such a stand at any time.

To produce the support according to the invention, the supports 4 are first attached to the housing base 10 in the required number and in the desired position determined by them and the container diameter, then the container with its container base 1 is simply placed on the supports 4 prepared in this way, with the webs 13 of these supports 4 inevitably fixing and centering it in its desired position. The space remaining between the container base 1 and the housing base 10 can then be filled with insulating material 3 - possibly at the same time as the casing of the container made of the same material - with the ring 5 resting snugly on the housing base 10 serving as a foam cover and as protection against distortion of this housing base 10.

The fixing foot screws 14 can now be used as height-adjustable feet or replaced with separate feet in order to set up the housing 2 and the container contained therein at its intended location simply and easily after the foaming process.
