Description
"Verfahren zur Herstellung von Grabmälern" Die Erfindung betrifft ein Verfahren zur Herstellung von Grabmälern oder ähnlichen Monumenten aus ktinstlichen Werk-Stoffen, insbesondere Kunststoff, sowie die nach dem Verfahren hergestellten Grabmälern oder Monumente."Process for the production of tombs" The invention relates to a process for the production of tombs or similar monuments from artificial ones Work materials, especially plastic, as well as those produced by the process Tombs or monuments.
Die Herstellung von Grabmälern aus gegossenen Kunststoffen ist bekannt. Der im allgemeinen verwendete Kunststoff besteht aus Polyesterharzen. Besitzt der herzustellende Gegenstand eine große Masse, werden durch innere Spannungen Verformungen und Risse verursacht, und zwar hauptsächlich deshalb, weil die Grabmäler eine Gewölbeform besitzen. Diese Nachteile können durch die Verwendung geeigneter FUllstoffe für die Masse verringert werden, wodurch Jedoch nur eine sehr geringe verbessernde Wirkung erzielt wird.The production of tombs from cast plastics is known. The plastic generally used is made of polyester resins. Does the The object to be manufactured has a large mass, deformations are caused by internal stresses and caused cracks, mainly because the tombs have a vault shape own. These disadvantages can be avoided by using suitable fillers for the mass can be reduced, whereby however only a very small improving effect is achieved.
Die Aufgabe der Erfindung besteht in der Schaffung eines Grabmals oder eines ähnlichen Monumentes, das die beschriebenen Nachteile nicht aufweist und sich mechanisch einwandfrei verhält.The object of the invention is to create a tomb or a similar monument that does not have the disadvantages described and behaves mechanically perfectly.
Bei dem üblichen Gießverfahren wird das Polyesterharz einfach zwischen eine Form und eine Gegenform gegossen; das auf diese Weise erzeugte Gußstück ist jedoch zerbrechlichß besitzt Ansätze zur Rißbildung in den Ecken und neigt dazu, sich unter seinem eigenen Gewicht durch Fließen oder Kriechen zu setzen bzw. zu senken.In the usual casting process, the polyester resin is simply between a mold and a counter-mold cast; is the casting produced in this way however, fragile has approaches to cracking in the corners and tends to to sit or crawl under one's own weight by flowing or crawling reduce.
Nach einem anderen bekannten Verfahren wird der Kunststoff zwischen eine Form und eine verlorene Gegenform (Kern) gegossen. Bei diesem Verfahren wird zwar die Setzneigung ausgeschaltet, doch erhöht sich die Gefahr der Rißbildung.According to another known method, the plastic is between a mold and a lost counter-mold (core) are cast. In this procedure, Although the tendency to settle is eliminated, the risk of cracking increases.
Bei dem Verfahren gemäß der Erfindung wird sowohl das Setzen als auch die Rißbildung ausgeschlossen. Die Erfindung besteht demgemäß im wesentlichen darin, daß zunächst vor dem Gießvorgang auf der Form und der Gegenform starre Schalen bildende Verkleidungen angebracht werden und hierauf der Werkstoff, insbesondere Kunststoff, zwischen die beiden, von der Form bzw.In the method according to the invention, both the setting and cracking excluded. The invention accordingly consists essentially in that first of all, before the casting process, rigid shells are formed on the mold and the counter-mold Cladding are attached and the material, in particular plastic, between the two, on the shape or
der Gegenform getragenen Schalen gegossen wird, derart, daß der Werkstoff die Verbindung zwischen den beiden Schalen herstellt. Wird nach dem Erstarren der Kunststoff entformt, sind die beiden Schalen durch diesen miteinander verbunden und bilden so das Grabmal bzw. das entsprechende Monument.the counter-mold supported shells is poured in such a way that the material establishes the connection between the two shells. Will solidify after the When plastic is removed from the mold, the two shells are connected to one another by this and thus form the tomb or the corresponding monument.
Man erhält auf diese Weise ein Grabmal oder Monument> das sich in gewölbter Form darstellt und aus dem ausgehärteten Kunststoff als Zwischenschicht-zwischen zwei starrenSehalen besteht.In this way one obtains a tomb or monument> that itself represents in a curved shape and made of the cured plastic as an intermediate layer-between consists of two rigid shells.
Als Kunststoff wird vorzugsweise Polyesterharz verwendet, während die beiden Schalen vorzugsweise aus glasfaserverstärktem Polyester bestehen.Polyester resin is preferably used as the plastic, while the two shells are preferably made of glass fiber reinforced polyester.
Die der Gagenform entsprechende, als Verkleidung dienende Schale wird vorteilhaft mit Veratärkungsrippen in Form von Hohlrippen verstehen, in welche das Gießharz nicht eindringen kann, so daß man auf diese Weise ein leichtes und gleichzeitig mechanisch festes Grabmal oder Monument erzielt.The shell, which corresponds to the shape of the fee and serves as a cladding, is understand advantageous with reinforcement ribs in the form of hollow ribs into which the Cast resin can not penetrate, so that you can easily and at the same time in this way mechanically solid tomb or monument achieved.
Zum leichteren Verständnis wird nachfolgend ein Beispiel für die Durchführung des erfindungsgemäßen Verfahrens beschrieben. In der Zeichnung zeigt Fig. 1 eine perspektivische Ansicht eines Grabmals gemäß vorliegender Erfindung, Fig. 2 und 3 einen Querschnitt bzw. Längsschnitt des Grabmals während des Ausformvorgangs.To make it easier to understand, an example of the implementation is shown below of the method according to the invention described. In the drawing, Fig. 1 shows a perspective view of a tomb according to the present invention, FIGS. 2 and 3 shows a cross-section or longitudinal section of the tomb during the shaping process.
Das Grabmal gemäß Fig. 1 besitzt eine im wesentlichen gewölbte Form und ist mit erfindungsgemäß hergestellten Versteifungen versehen.The tomb according to FIG. 1 has a substantially curved shape and is provided with stiffeners produced according to the invention.
Für das Formen verwendet man eine Form 1 und eine Gegen form 2, wobei der verwendete Kunststoff 5 zwischen diese beiden Formen gegossen wird. Zum Zentrieren der Gegenform 2 mit Bezug auf die Form 1 werden in der Formtechnik bekannte Zentriermittel vorgesehen. Der Kunststoff besteht vorzugsweise aus Polyesterharz. Vor dem Gießen des Kunststoffes werden passend gefärbte Polyesterharztröpfchen (Gelcoat) aufgetragen, um z.B.A form 1 and a counter-form 2 are used for molding, whereby the plastic 5 used is poured between these two molds. For centering of the counter-mold 2 with respect to the mold 1 are centering means known in molding technology intended. The plastic is preferably made of polyester resin. before When the plastic is poured, appropriately colored polyester resin droplets (gelcoat) applied to e.g.
Granit zu imitieren.Imitating granite.
Bei dem Verfahren gemäß Erfindung versieht man die Form 1 mit einer starren Verkleidung 4, die eine Art Außenschale bildet. Auf gleiche Weise erhält die Gegenform 2 eine starre Innenverkleidung 5. Diese Verkleidungen bestehen aus glasfaserverstärktem Polyester und können mit der Spritzpistole aufgetragen werden. Anschließend wird die Form 1 mit einer bestimmten Menge Kunststoff 7 gefüllt, die ausreicht, um den Zwischenraum zwischen den beiden Schalen 4, 5 auszufüllen, wenn die Gegenform 2 unter Druck in die dargestellte Stellung gepreßt wird.In the method according to the invention, the mold 1 is provided with a rigid cladding 4, which forms a kind of outer shell. Received in the same way the counter-form 2 a rigid inner lining 5. These linings consist of glass fiber reinforced polyester and can be applied with a spray gun. Then the mold 1 is filled with a certain amount of plastic 7, the sufficient to fill the space between the two shells 4, 5, if the counter-mold 2 is pressed under pressure into the position shown.
Die Innenschale 5 besitzt vorzugsweise zwei Rippen- 6 und 7, die gleichzeitig mit der Schale 5 hergestellt werden. Mit anderen Worten, die Gegenform 2 und ebenso die Schale 5 weisen zwei hohle Einbuchtungen zur Bildung dieser Rippen auf. Die Rippen werden dann bei 8 so verschlossen, daß das Harz 3 beim Ausformvorgang nicht in die Rippen eindringen kann. Das Verschließeh läßt sich auf einfache Weise dadurch erzielen, daß eine Platte geeigneter Größe aufgebracht wird, deren Befestigung durch Aufbringen des gleichen Schichtmaterials (z.B.The inner shell 5 preferably has two ribs 6 and 7, which at the same time can be made with the shell 5. In other words, the counter-form 2 and likewise the shell 5 have two hollow indentations to form these ribs. the Ribs are then closed at 8 so that the resin 3 does not occur during the molding process can penetrate the ribs. The closure can be done in a simple manner achieve that a plate of suitable size is applied, its attachment by Applying the same layer material (e.g.
aus glasfaserverstärktem Polyester) wie für die Schale an den Kanten mittels einer Pistole erfolgt. Vor dem Verschließen kann vorteilhaft eine Holzleiste auf den Grund der Rippen eingelegt werden, um deren Festigkeit zu erhöhen.made of glass fiber reinforced polyester) as for the shell on the edges done by means of a pistol. Before closing it can be advantageous to use a wooden strip placed on the bottom of the ribs to increase their strength.
Nachdem der Kunststoff 3 erstarrt ist, wird die Gegenform 2 entfernt und das auf diese Weise hergestellte Grabmal aus der Form 1 entnommen, indem man es an den Oeffnungen 9 in den Rippen 6, 7 herauszieht. Das Vorhandensein der Holzleisten ist besonders für diesen Arbeitsgang von Vorteil.After the plastic 3 has solidified, the counter-mold 2 is removed and the tomb thus produced is removed from mold 1 by it pulls out at the openings 9 in the ribs 6, 7. The presence of the wooden battens is particularly advantageous for this operation.
Das so hergestellte Grabmal besteht aus einer Kunststoffmasse 5 als Zwischenschicht zwischen den beiden Schalen 4 und 5. Dieser Aufbau ist für Grabmale von Vorteil, da dadurch für einen Gegenstand aus Kunststoff in gewölbter Form eine besonders hohe mechanische Festigkeit erzielt wird.The tomb produced in this way consists of a plastic compound 5 as Intermediate layer between the two shells 4 and 5. This structure is for grave monuments This is advantageous because it has a curved shape for an object made of plastic particularly high mechanical strength is achieved.
Bei einer anderen Ausführungsart des erfindungsgemäßen Verfahrens wird die Innenschale (entsprechend der Gegenform 2) auf einer Gußform hergestellt, die die gleiche Form wie die Gegenform 2 hat, wobei die Gegenform 2 erst im Augenblick des Formvorgangs mit dieser Schale versehen wird. Diese TechnikXermöglioht eine kürzere Belegung der Formvorrichtung für die Herstellung der Schalen.In another embodiment of the method according to the invention the inner shell (corresponding to counter shape 2) is made on a mold, which has the same shape as the counter-shape 2, the counter-shape 2 only at the moment of the molding process is provided with this shell. This technology allows one shorter occupancy of the molding device for the production of the shells.
