Glasfasern gelegt. Diese Verbundplattenkonstrul (tion, als innerer Behälter ausgebildet, hat folgende Auf- gaben :
Durch eine freihängende oder freistehende Befestigung auf der inneren Tankwandung des äusseren Be- halters, z.

EMI2.2
innere Behälter ist für sich treibstoff- und heizöldicht und-beständig, so dass er gegenüber dem äusseren
Behälter alsDichtung für das Füllgut wirkt, wogegen der äussere Behälter die statische Belastung des Füll- igutes übernimmt ; d. h. der statische Druck überträgt sich vom inneren Behälter direkt auf die Beton- oder
Stahltankkonstruktion.
Das erfindungsgemässe Verfahren zur Erreichung einer freistehenden oder freihängenden kunstharz- beschichteten Schaumstoffauskleidung besteht darin, dass man die einzelnen Platten stumpf aneinander- legt oder aber mit Nut oder Falz an den Stirnflächen verlegt, worauf dann die Fuge mit einer Epoxyd- harzspachtelmasse überstrichen wird, welche vorzugsweise mit flüssigen Polysulfid-Verbindungen, welche mit der Epoxydhärterkomponente reagieren, elastifiziert werden, und ein Deckstreifen, bestehend aus einer epoxydharzbeschichteten Schaumstoffmatte mit der gleichen Spachtelmasse aufgeklebt wird.
Der so fertiggestellte innere Behälter wird hierauf nochmals mit einer Deckschicht Epoxydharz, die vorzugsweise thixotrop und lösungsmittelhaltig ist. eingestellt, bestrichen, wobei diese Deckschicht auf die Platten. auf die Fugenbänder und auf dieStirnflächen derFugenbänder gestrichen oder gespritzt wird, so dass eine ho- mogene Schicht die ganze innere Tankwandung überdeckt.
Um eine eventuelle Undichtheit im inneren Tankraum bzw. in der beschichteten Schaumstoffmatte sofort feststellen zu können, wird erfindungsgemäss am tiefsten Punkt der Tankanlage ein Ablaufrohr nach aussen geführt, welches dann auf die Höhe des vorgesehenen Füllgutes vertikal an der äusseren Tankwan- dung in Form einer kommunizierenden Röhre wieder emporsteigt. Hiebei wird die Bohrung durch die äussere Tankwandung geführt, nicht aber durch den 5chaumstoffinnenbehälter. Im senkrechten Teilstück der kommunizierenden Röhre wird, vorzugsweise mit elektromagnetischer Steuerung durch einen even- tuellen Flüssigkeitsspiegel eine optische oder akustische Warnanlage betätigt. Tritt Flüssigkeit in das senkrechte Rohrstück, so zeigt dies automatisch eine Undichtheit des inneren Behälters an.
Aus Sicherheitsgründen kann auch die innere Tankwandung des äusseren Behälters mit einer oder zwei
Schichten Epoxydharz beschichtet werden, so dass bei einer eventuellen Undichtheit des inneren Behäl-

EMI2.1
To change the ductility of the foam mats in such a way that they can be walked on without the risk of notches, according to the invention a mat, a fleece or a woven fabric of epoxy resin is used between the individual layers
Glass fibers laid. This composite panel construction, designed as an inner container, has the following tasks:
A freely hanging or free-standing attachment on the inner tank wall of the outer container, e.g.
B. by fixing the mats point by point with elastic synthetic resin adhesives, especially adhesive
EMI2.2
inner container is fuel- and heating oil-tight and -resistant, so that it is against the outer
The container acts as a seal for the product, whereas the outer container takes on the static load on the product; d. H. the static pressure is transferred from the inner container directly to the concrete or
Steel tank construction.
The method according to the invention for achieving a free-standing or free-hanging synthetic resin-coated foam lining consists in laying the individual panels butt against each other or laying them with a groove or fold on the end faces, after which the joint is then coated with an epoxy resin filler, which is preferably with liquid polysulphide compounds, which react with the epoxy hardener component, are elasticized, and a cover strip consisting of an epoxy resin-coated foam mat is glued with the same filler.
The inner container finished in this way is then covered again with a cover layer of epoxy resin, which is preferably thixotropic and contains solvents. set, coated, this top layer on the plates. is painted or sprayed on the waterstops and on the front surfaces of the waterstops so that a homogeneous layer covers the entire inner tank wall.
In order to be able to immediately detect a possible leak in the inner tank space or in the coated foam mat, according to the invention a drain pipe is led to the outside at the lowest point of the tank system Tube rises again. The hole is made through the outer tank wall, but not through the inner foam container. In the vertical section of the communicating tube, an optical or acoustic warning system is activated, preferably with electromagnetic control, by a possible liquid level. If liquid enters the vertical pipe, this automatically indicates a leak in the inner container.
For safety reasons, the inner tank wall of the outer container can also have one or two
Layers of epoxy resin are coated so that in the event of a leak in the inner container
