holder base for inner container,

The invention is seen on a container base for Inner container of double-walled standing storage containers ■ with one liquid each, covers welded-on cover and ■ with a Lvokansaigvorriohtung for storage in particular von fittaaigan Kraftatoffen «consisting of one for the Exftvs AuSeabehaiters made of thinner sheet metal on the rough floor dimensioned to withstand loads standing inner container

In these known double-walled storage containers the ZVlsohenraua between the outer container and the inner container according to the regulations with a control liquid filled, the change of which is monitored by the leak detection device However, the fuel level affects the column of control fluid alt the overpressure from the outside on the jacket and on the floor of the corresponding to their free height Inner container · There is a risk that the shell and bottom of the inner container dented becomes »if the latter is not a priori for those to be included Is adequately dimensioned to withstand the stresses and strains. This is particularly the case when the inner container contains little fuel or is completely empty

In order to make the storage container not too heavy and in terms of weight To make it not too expensive to manufacture, the jacket of the inner container can, for example, on the inside Stiffened by Sine · with an L-f »fBig * a profile will. The one to achieve good health However, flat ground is mainly dimensioned so strongly that denting is not possible. Of course, it can be made of a thinner material and also by means of welded profile elements However, these hinder the cleaning of the inner container and cause the welding process warping of the container bottom and thus additional machinable marks

The invention is therefore intended to solve the problem the well-known container bottom for inner containers from dcppelwandigen standing storage containers with the other features of the genus explained at the beginning in the first paragraph by means of simple and economically feasible measures to develop so that despite an αβη static Not completely absorbing the pressure of the control liquid Sheet thickness of the inner bottom not even when the inner container is empty due to the pressure of the control liquid • Get dented »

This task is solved in simple terms by that the water-tight welded to the interior mast Xnneiaboden of daehzlegelartie arranged one on top of the other.

Neten material «or sheet metal strips formed and with the outer bottom, which is welded to the outer casing in a liquid-tight manner, is liquid-permeable.

In particular, the training can be carried out so that the outer floor from one with the uneven side inwardly or upwardly directed checker plate is formed, on which an outer material or sheet metal strip of the inner bottom on both long sides, the following strips of material or sheet metal, however, only with the Each long side lying on the outer floor is fastened in a fluid-permeable manner by tack welding are «The material- or sheet metal strips of the inner booth are along their free long sides are welded to one another and to the inner jacket along its foot edge in a liquid-tight manner The arrangement or design can be such that the inner bottom has one of the clear widths of the inner container has a corresponding contour shape · Finally, however, the inner bottom can be used to hold the outer jacket with a corresponding approximately to the clear width of the outer container Outline shape and size. · Um-. first In the case of the inner bottom is welded into the jacket of the inner container, in the second case, however, is the inner jacket welded to the interior floor

These measures create a floor that is not rigid

for the main or «inner container created» without the Thickness of the soil can be made so large that through the material thickness of the flat inner bottom is only slightly filled or empty inner container, the denting under the influence of the control liquid column is prevented A construction of the inner bottom carried out according to the invention for double-walled standing storage containers is particularly important »if the standing storage containers have a relatively large height · The one above the other lying and welded together areas of the sheet metal strips of the inner floor have an air »reinforcement strip— fen or "as reinforcing ribs, whereas the white spots" This welding of the metal strips was used to stiffen the inner floor is without, however, washing around the inner floor with the control liquid completely surrounding the inner container is obstructed or interrupted «The space formed by the height of the warts of the outer floor is sufficient «about the tightness of the inner container too La floor area to be monitored reliably · In this way becomes an interior floor that takes account of all demands with relatively little construction effort created for double-walled standing storage containers »which are characterized by a high level of economic efficiency.

The invention is intended below with the aid of two embodiments

examples are explained in more detail · In the associated Drawing show:

The illustrated double-walled and upright storage container 1 is used to hold mainly liquid ICraftetoffen _t heating oils or the like. Such double-walled storage containers have to be used to protect the groundwater, whereby the storage container serves as a collecting container for any leakage liquid that may leak out of the main container and which collects in the double-walled space between the two containers, however, single-walled storage containers can also be provided In this case, however, such a storage container must be brewed or set up in a concrete tub of the same volume. In both exemplary embodiments, there is a cylindrical cross-section shape for the storage container

In this plate, the outer shell can be liquid-tightly k along its bottom edge to be welded _e in this case is the outer bottom 8 h somewhat over the periphery of the outer shell.
