Description

  

  Verfahren zur Herstellung eines Gipskörpers, welcher zur Aufnahme einer nassen,  nach Erstarrung fest anhaftenden Schicht aus Zement oder anderem ähnlichen  Stoff geeignet ist.    Die vorliegende Erfindung betrifft ein  Verfahren     zurHerstellung    eines<B>G</B>     1-"köi-pei-s,     welcher     zur    Aufnahme einer nassen, nach  Erstarrung fest     anhaftenden-    Schicht aus  Zement oder anderem ähnlichen Stoff ge  eignet ist.

   Dieses Verfahren kennzeichnet  sieh dadurch,     dass    man zur Herstellung von  zu     Verankerungszwecken    dienenden Vorsprün  gen und Vertiefungen am Gipskörper diesen  an eine mit entsprechenden Vertiefungen und  Vorsprüngen versehene     biegsameForniplatte          berangiesst    und dieselbe nach Erstarren des  Gipskörpers von diesem abzieht, so     dass    am  Gipskörper die für direkte Verankerung ei  ner Deckschicht nötigen Vorsprünge und Ver  tiefungen blossgelegt werden.  



  Das Abziehen der Formplatte     lässt    sich  vermöge der Biegsamkeit derselben leicht       und    ohne Beschädigung der Profilform der  am Gipskörper vorhandenen     Verankerungs-          vorsprünge    vornehmen. Zweckmässig verwen  det man als Formplatte eine Gummiplatte    mit abwechselnden     schwalbenschwanzförmig     profilierten Rippen und     Nut6D,    so     dass    am  Gipskörper ebensolche Rippen und Nuten  entstehen, wobei in diesem Falle die Rippen  der Platte beim Abziehen derselben vermöge  der Elastizität des Materials leicht zwischen  den Rippen des Gipskörpers herausgezogen  werden können.

   Auf diese blossgelegte ge  rippte Oberfläche des Gipskörpers kann dann  direkt eine nasse., nach Erstarrung fest an  haftende Schicht aus Zement oder anderem  ähnlichen Stoff aufgebracht werden.  



  Die beiliegende Zeichnung dient zur Er  läuterung eines Ausführungsbeispiels des  Verfahrens. A ist ein Gipskörper und B eine  mit     schwalbenschwanzförmigen    Rippen und  Nuten versehene     Cxummiplatte,    an welche  der Gipskörper     herangegossen    ist, um die  Rippenform derselben anzunehmen, und die  von ihm dadurch leicht entfernt werden  kann,     dass    man sie     an    einem vorspringenden  Ende     erfasst    und vom     Gipshörper    abzieht.



  Process for the production of a plaster of paris, which is suitable for receiving a wet, firmly adhering layer of cement or other similar material after solidification. The present invention relates to a method for the production of a G 1- "köi-pei-s, which is suitable for receiving a wet layer of cement or other similar material that is firmly adhering after solidification.

   This method is characterized by the fact that in order to produce projections and depressions on the plaster of paris, which are used for anchoring purposes, this is poured onto a flexible form plate provided with corresponding depressions and projections and, after the plaster of paris body has solidified, the same is removed from the plaster body so that the plaster of paris body with direct ner cover layer necessary projections and depressions Ver are exposed.



  Due to its flexibility, the molding plate can be pulled off easily and without damaging the profile shape of the anchoring projections present on the plaster body. It is advisable to use a rubber plate with alternating dovetail-shaped ribs and grooves6D as the molding plate, so that the same ribs and grooves are created on the plaster body, in which case the ribs of the plate are easily pulled out between the ribs of the plaster body when they are pulled off due to the elasticity of the material can.

   On this exposed, ribbed surface of the plaster of paris, a wet layer of cement or other similar material can then be applied directly after it has solidified.



  The accompanying drawing is used to explain one embodiment of the method. A is a plaster of paris body and B is a cxum plate with dovetail-shaped ribs and grooves, onto which the plaster of paris is cast to assume the rib shape of the same, and which can easily be removed from it by grasping it at a protruding end and pulling it off the plaster body .
