Description
Vorrichtung zur Herstellung doppelwandiger Dachziegel aus thermoplastischem Kunststoff In der Bauindustrie wurden Dachziegel der verschiedensten Formen bisher durch Brennen keramischer Massen hergestellt. Es ist auch bekannt, Dachziegel aus Kunststoffen durch Gießen oder Pressen herzustellen. Nach den bisherigen Verfahren konnte man nur einwandige Dachziegel anfertigen.Device for the production of double-walled roof tiles from thermoplastic Plastic In the construction industry, roof tiles of the most varied shapes have been used up to now produced by firing ceramic masses. It is also known to be made from roof tiles Manufacture plastics by casting or pressing. According to the previous procedure you could only make single-walled roof tiles.
Es wurde gefunden, daß in der neuen Vorrichtung doppelwandige Dachziegel aus thermoplastischen Kunststoffen nach dem Rotationsgußverfahren hergestellt werden können. Die neue Vorrichtung besteht aus den Formteilen 1 und 2 mit den Hohlbolzen 5 bzw. Hohlrippen 6, den Schrauben 3 und dem Gewindestück 4.It has been found that double-walled roof tiles in the new device made of thermoplastics by the rotational molding process can. The new device consists of the molded parts 1 and 2 with the hollow bolts 5 or hollow ribs 6, the screws 3 and the threaded piece 4.
Die Wirkungsweise der Vorrichtung läßt sich aus den in den Abbildungen 1 und 2 dargestellten Ausführungsformen entnehmen. In das Formteil 1 wird der thermoplastische Kunststoff (7) eingebracht. Als thermoplastische Kunststoffe sind dabei z. B. Polyvinylchlorid-Plastisole mit 20 bis 50 % Weichmacher geeignet. Die zu verwendende Menge richtet sich nach der erwünschten Wandstärke, wobei selbstverständlich in jedem Falle das Formteil 1 nur zum Teil mit der Kunststoffpaste zu füllen ist. Danach wird das Formteil 2 mit Hilfe der Schrauben 3 mit dem Teil 1 fest verbunden. Die auf diese Weise verschlossene Hohlform wird nun durch das Gewindestück 4 mit der Kopfplatte einer Rotationsgußmaschine verbunden und in 2 zueinander senkrechten Ebenen unter Beheizung mit einem heißen Luftstrom bewegt. Dabei geliert die Kunststoffpaste an den Innenflächen zu einem Hohlkörper mit gleicher Wandstärke. Die Höhe der Hohlbolzen 5 bzw. Hohlrippen 6 ist so zu bemessen, daß sich die daran angelierte Kunststoffpaste mit der Wandung des Hohlkörpers verbindet, um ihn dadurch biegungssteif zu machen. Die Anordnung der Versteifungsbolzen-bzw. Versteifung. s rippen kann man aus den Abbildungen 3 und 4 entnehmen. Wird als Kunststoff beispielsweise Polyvinylchlorid verwendet, soll die Temperatur in der Vorrichtung etwa 170° C bei einer Gelierzeit von 10 bis 20 Minuten je nach Wandstärke betragen. Nach ausreichender Abkühlung kann die Vorrichtung geöffnet und der doppelwandige Dachziegel entnommen werden. Mit der vorliegenden Vorrichtung können Dachziegel der handelsüblichen Formen hergestellt werden, die wegen der Ausbildung als Hohlkörper besonders gut sowohl gegen Kälte als auch gegen Wärme isolieren.The mode of operation of the device can be seen in the figures 1 and 2 shown embodiments. In the molded part 1 is the thermoplastic Plastic (7) introduced. As thermoplastics are z. B. polyvinyl chloride plastisols suitable with 20 to 50% plasticizer. The amount to be used depends on the desired wall thickness, of course in each case the molded part 1 only has to be partially filled with the plastic paste. Then the molded part 2 firmly connected to part 1 with the aid of screws 3. The one locked in this way The hollow shape is now made by the threaded piece 4 with the head plate of a rotary casting machine connected and in 2 mutually perpendicular planes under heating with a hot Moving airflow. The plastic paste gels on the inner surfaces one Hollow body with the same wall thickness. The height of the hollow bolts 5 or hollow ribs 6 is to be dimensioned in such a way that the plastic paste that has gelled on it adheres to the wall of the hollow body connects in order to make it flexurally rigid. The order the stiffening bolt or. Stiffening. s can be seen in Figures 3 and 4. If the plastic used is, for example, polyvinyl chloride, the temperature in the device should be around 170 ° C with a gel time of 10 to 20 minutes depending on the wall thickness. After cooling down sufficiently, the device can opened and the double-walled roof tiles removed. With the present Device can be produced roof tiles of the commercially available forms, the because of the design as a hollow body particularly good against both cold and against Insulate heat.
