Abstract

A laminated plate to keep rising damp away from the foundations of buildings consists of a baseplate with projections on the side contacting the foundation so that vertical drainage channels are formed. This baseplate is covered on the outside by a drainage layer, protected by a perforated sheet of metal or plastics material. The baseplate can be made of metal or a rigid plastics. The porous drainage layer consists of glass fibre, rock wool or open-celled plastics foam. Such a laminated plate is easy to manufacture and achieves optimum protection against rising damp. PS.

Description

der Grundmauer 1 abgewandten Hohlräume der Rippen 3 vollständig oder teilweise frei vom Material der Dränierschicht 6, wodurch auf der Außenseite der Tafel 2 vfnikale Dränierkanäle 8 gebildet werden. Bei den Ausführungsbeispielen gemäß Fig.3 und 4 sind vertikale Dränierkanäle 8 dadurch gebildet, daß das Material der Dränierschicht 6 an dem tafelförmig^^ Element 2 entsprechende Ausnehmungen aufweist.The cavities of the ribs 3 facing away from the foundation wall 1 are completely or partially free of the material of the drainage layer 6, whereby vfnical drainage channels 8 are formed on the outside of the panel 2. Both Embodiments according to FIGS. 3 and 4 are vertical Drainage channels 8 formed in that the material of the drainage layer 6 on the tabular ^^ element 2 has corresponding recesses.

Vom außen an der Tafel angeschütteten Erdreich (in den Figuren jeweils rechts) andrängende Feuchtigkeit wird teils durch die Dränierschicht 6 und teils nach Passieren der Drärisrschicht 6 durch die Dränierkanäle 8 nach unten abgeleitet, vergleiche die in F i g. 1 eingezeichneten Pfeile. Im Vergleich zu einer Tafel ohne Dränierkanäle 8 kann die Dränierschicht 6 dünner sein.Moisture pressing in from the soil on the outside of the board (on the right in each of the figures) is partly through the drainage layer 6 and partly through the drainage channels 8 after passing the drainage layer 6 derived downwards, compare that in FIG. 1 drawn arrows. Compared to a board without drainage channels 8, the drainage layer 6 can be thinner.

Bei der Ausführungsform gemäß F i g. 3 ist außen auf der Dränierschicht 6 ein gelochtes Abdeckblech 7 vorgesehen, das die Dränierschicht 6 schützt Statt des Abdeckblechs 7 kann auch eine gelochte Kunststoffschicht vorgesehen sein.In the embodiment according to FIG. 3 a perforated cover plate 7 is provided on the outside of the drainage layer 6, which protects the drainage layer 6 Instead of the cover plate 7, a perforated plastic layer can also be used be provided.

Beim Ausführungsbeispiel gemäß F j g. 4 ist ein seitlicher Randabschnitt 2* der Tafel nicht mit dem Material 'der Dränierschicht 6 belegt Die benachbarte Tafel ist unter Überlappung der tafelförmigen Elemente 2 ange-In the embodiment according to FIG. 4 is a side one Edge section 2 * of the board is not covered with the material of the drainage layer 6 The adjacent board is overlapping the tabular elements 2

setzt, so daß ein Randabschnitt der benachbarten Tafel über den von der Dränierschicht 6 freien Randabschnitt 2' greift Dabei greifen die Nasen 3 der benachbarten Tafel in die Rückseiten der Nasen 3' ein. Dies ergibt einen guten Zusammenhalt der benachbarten Tafelnsets so that an edge portion of the adjacent panel engages over the edge section 2 'free of the drainage layer 6. The noses 3 of the adjacent ones engage Plate in the back of the noses 3 '. This results in good cohesion of the neighboring panels

ίο und zugleich eine verbesserte Abdichtung gegen Durchdringen von Wasser an dieser Stelle.ίο and at the same time an improved seal against penetration of water at this point.

Das tafelförmige Element 2 und/oder die Abdeckschicht 7 können auch dadurch gebildet werden, daß ein poröser Werkstoff, beispielsweise Schaumkunststoff,The tabular element 2 and / or the covering layer 7 can also be formed in that a porous material, for example foam plastic,
