Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Bauteilen aus mindestens einer Platte aus gebranntem Ton, abgebundenem Gips oder gebundenem Schieferpulver mit z. B. längsverlaufenden Rippen und einer Schicht eines Phenolharz-SchaumstoffS; bei dem die Platten im Rahmen ihrer Herstellung erwärmt und eine Schäummasse auf der Basis des Phenolharzes aufgetragen, aufgeschäumt und ausgehärtet wird.The invention relates to a method for producing components from at least one plate Fired clay, set plaster of paris or bound slate powder with z. B. longitudinal ribs and a layer of phenolic resin foam S; in which the panels are heated as part of their manufacture and a foaming compound based on the phenolic resin is applied, foamed and cured.
Im Rahmen der Entwicklung der Fertigbauweise hat man sich bemüht, große Bauteile vorzufertigen, die ein schnelles Aufziehen von Mauern, Wänden und Böden ermöglichen. Zu diesem Zwecke wurden Profile und Platten oder Füllungen aus Beton geformt. Dann hat man versucht, diese Bauteile leichter zu machen und ihre Isoliereigenschaften zu verbessern. Infolgedessen wurden Bauteile aus Leichtbeton oder Bauteile mit Hohlräumen hergestellt. Im Rahmen einer Verbesserung der Hohlblöcke hat man versucht, diese mit einem Schaumstoff, beispielsweise mit einem geschäumten Kunststoff in Form von Granulat oder Bändern, zu füllen.As part of the development of prefabricated construction, efforts have been made to prefabricate large components that contain a enable walls, walls and floors to be erected quickly. For this purpose profiles and Slabs or fillings molded from concrete. Then an attempt was made to make these components lighter and theirs To improve insulation properties. As a result, components were made of lightweight concrete or components with Cavities produced. As part of an improvement in the hollow blocks, attempts have been made to use a Foam, for example with a foamed plastic in the form of granules or ribbons, too to fill.
Eine andere Möglichkeit zur Industrialisierung des Bauwesens beruht auf der Verwendung von großen Profilen und Platten auf der Basis von Terracotta, von Gips aus der Phosphorsäureherstellung oder der Herstellung von Dachplatten, die das Aussehen von Schiefer haben. Beispiele für Produkte aus Terracotta bzw. gebranntem Ton sind solche, die nach dem Verfahren von »Centre Technique des Tuiles et Briques« hergestellt werden. Diese Produkte aus gebranntem Ton oder Terracotta haben verbesserte mechanische Eigenschaften; die Ausgangsstoffe sind reichlich vorhanden und billig und die Herstellung einfach und kostensparend, weil der Energieaufwand wenig ins Gewicht fällt. Im Rahmen der Herstellung solcher Platten kommt es beim Abbinden zu exothermen Reaktionen, so daß die Platten noch warm von der Fertigungsstraße kommen. Keramikplatten müssen gebrannt werden und verlassen mit erhöhter Temperatur den Brennofen. Es stehen somit Platten zur Verfügung, die mit etwa 40 bis 800C aus ihrer Fertigung kommen.Another way of industrializing construction is to use large profiles and panels based on terracotta, gypsum from phosphoric acid production or the production of roofing panels that have the appearance of slate. Examples of products made from terracotta or baked clay are those manufactured using the “Center Technique des Tuiles et Briques” method. These baked clay or terracotta products have improved mechanical properties; The starting materials are abundant and cheap and the production is simple and cost-saving because the energy consumption is negligible. In the course of the production of such panels, exothermic reactions occur during setting, so that the panels come off the production line while still warm. Ceramic plates have to be fired and leave the kiln at a higher temperature. There are thus plates available that come out of their production with about 40 to 80 ° C.
Phenolharz-Schaumstoffe und deren Herstellung sind allgemein bekannt und werden für die verschiedensten Zwecke angewandt. Die Schäummassen können pulverige oder faserige anorganische Füllstoffe wie Talkum, Glimmer, Kreide, Kieselsäure, Asbest, Glasfasern oder Asbestfasern enthalten.Phenolic resin foams and their production are well known and are used for the most diverse Purposes applied. The foam compounds can be powdery or fibrous inorganic fillers such as talc, Contains mica, chalk, silica, asbestos, glass fibers or asbestos fibers.
Die Phenolharz-Schäummasse enthält üblicherweise einen sauren Katalysator und ein Treibmittel. Für die Herstellung des Phenolharzes werden Phenol, substituierte Phenole wie Kresole, Xylenole oder Diphenole (Resorcin, Hydrochinon) angewandt Anstelle von wäßrigem oder polymerisiertem Formaldehyd kann auch Hexamethylentetramin, Acetaldehyd, Butyraldehyd und Aceton dienen. Das Resol kann durch Furfurylalkohol, Polyvinylalkohol oder dessen Ester, Nitrilkautschuk, Catechuöl oder Holzteer modifiziert sein.The phenolic resin foam composition usually contains an acidic catalyst and a blowing agent. For the Phenolic resin is produced using phenol, substituted phenols such as cresols, xylenols or diphenols (Resorcinol, hydroquinone) can be used instead of aqueous or polymerized formaldehyde Hexamethylenetetramine, acetaldehyde, butyraldehyde and acetone are also used. The resol can go through Modified furfuryl alcohol, polyvinyl alcohol or its esters, nitrile rubber, catechu oil or wood tar be.

Es sind ferner Bauteile bekannt, die aus einer Schicht aus einem Phenolharz-Schaumstoff und einer Platte oder dergleichen bestehen. Für die Herstellung sind zwei Verfahren bekannt.There are also known components that consist of a layer of a phenolic resin foam and a plate or the like exist. Two processes are known for the production.

F i g. 1 ist ein Schnitt durch ein Bauteil mit einer Platte.F i g. 1 is a section through a component with a plate.
Fig.2 ist ein Schnitt durch ein Bauteil mit zwei Platten.Fig.2 is a section through a component with two Plates.
Das in F i g. 1 gezeigte Element 1 weist als eine Platte einen Grundteil mit Seitenteilen, Längsrippen 2 und T-förmige Rippen 3 auf. Selbstverständlich kann auch eine Platte ohne Seitenteile vorgesehen sein. Die Schäummasse wird in diesem Fall während des Aufschäumens durch entfernbare Wände begrenzt. Beim Austritt der Platte aus dem Brennofen wird, solange sie noch warm ist, in den Raum 4 auf die Platte 1 die Grundierung 5 (stark ausgezogen) aufgebracht und dann die Schäummasse eingegossen. Auf den Schaumstoff, der den Raum 4 ausfüllt, kann man nach dem Beschneiden noch eine Abdeckung 6, beispielsweise in Form von Aluminium-Kraftpapier, einem Gewebe, einer Gipsbauplatte oder einer Platte aus Faserzement oder aus Sperrholz, auflegen.The in Fig. 1 shown element 1 has as a plate a base part with side parts, longitudinal ribs 2 and T-shaped ribs 3 on. Of course, a plate without side parts can also be provided. the Foaming compound is in this case limited by removable walls during foaming. When the plate emerges from the kiln, as long as it is still warm, it enters space 4 on plate 1 the primer 5 (strongly drawn out) applied and then poured the foam compound. On the foam, who fills the room 4, you can after the Trimming another cover 6, for example in the form of aluminum kraft paper, a fabric, a plasterboard or a board made of fiber cement or plywood.
