Abstract

New building elements for building constructions made of brick or concrete hollow blocks, the cavities in the bricks or blocks being filled with Styrofoam (polystyrene and the like). To manufacture these building elements, the hollow bricks are lined up on a perforated silicone sheet with their cavities vertical. Dull-edged polystyrene particles are poured in from above. A perforated sheet of silicone plastic is then likewise laid on top. Steam under pressure or another source of heat is then applied, as a result of which the polystyrene particles expand (foam) and thus fill all the cavities. Insulating but at the same time strong building elements are thus obtained in a simple, inexpensive manner and the buildings produced therefrom do not need to be insulated with a separate layer of insulating material. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Konstruktionselements nach Anspruch 1 bzw. danach hergestellte Konstruktionselemente oder Bauteile für das Bauwesen, insbe­sondere den Hochbau.The invention relates to a method for producing a construction element according to claim 1 or construction elements or components produced according to it for the building industry, in particular building construction.

Im Bauwesen ist bekanntlich die Schall- und Wärmeisolierung sehr wichtig. Bischer müssen zur thermischen und akustischen Isolierung einer Wohnung bzw. eines Gebäudes die Wände mit einer Schicht aus Iso­liermaterial verkleidet werden. Dies ist sehr teuer, ferner werden die Wände entsprechend dicker, d.h. die Wohnfläche wird entsprechend kleiner.It is well known that sound and heat insulation is very important in construction. For thermal and acoustic insulation of an apartment or building, the walls must be clad with a layer of insulating material. This is very expensive, and the walls become correspondingly thicker, i.e. the living space is correspondingly smaller.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, Bau­elemente bzw. ein Verfahren zur Herstellung von Bauelementen zu schaffen, welche gleichzeitig tragen und isolieren, mit denen also ausreichend isolierte Gebäude ohne äußere, gesonderte Isolationshaut erstellt werden können. Dabei sollen der größtmögliche Raum für die Statik sowie die kleinstmögliche Wärmeübertragung erreicht werden.In contrast, the invention has for its object to provide components or a method for producing components that support and isolate at the same time, with which therefore sufficiently insulated buildings without external, separate insulation skin can be created. The largest possible space for the statics and the smallest possible heat transfer should be achieved.

Die Lösung dieser Aufgabe ist im Patentanspruch 1 angegeben; das Verfahren nach Anspruch 1 wird durch die Verfahren nach Ansprüchen 2 und 3 weiter ausgestaltet. Die Ansprüche 4 und 5 sind auf die so hergestellten Bauelemente selbst gerichtet.The solution to this problem is specified in claim 1; the method according to claim 1 is further developed by the method according to claims 2 and 3. Claims 4 and 5 are directed to the components thus produced themselves.

Gemäß der Erfindung wird im allgemeinen eine Reihe von Hohl­steinen auf eine Schicht oder Platte aus fein durchlöchertem Silikonmaterial aufgereiht, und zwar so, daß die durchgehenden Hohlräume vertikal angeordnet sind. In die Hohlräume werden ungeschäumte Styroporpartikel gefüllt. Die Styroporkörner können unterschiedliche Dichte haben und ergänzen sich gegenseitig. Oben auf die Reihe wird eine weitere Schicht oder Platte aus perforiertem Silikon aufgebracht. Durch die besagte, perforierte Silikonplatte bzw. Schicht bzw. durch beide Schichten wird Wasserdampf unter Druck aufgebracht, also in die mit Styroporkörnchen gefüllten Hohlräume injiziert: Hierdurch wird das Styropormaterial ausgeschäumt, so daß es den gesamten Hohlraum ausfüllt, insebesondere sich an die inneren Wände der Hohlsteine anlegt und anhaftet.According to the invention, a series of hollow stones is generally lined up on a layer or plate of finely perforated silicone material, in such a way that the continuous cavities are arranged vertically. Non-foamed polystyrene particles are filled into the cavities. The styrofoam grains can have different densities and complement each other. Another layer or plate of perforated silicone is applied to the top of the row. Through said perforated silicone plate or layer or through both layers, water vapor is applied under pressure, i.e. injected into the cavities filled with polystyrene granules: this foams the polystyrene material so that it fills the entire cavity, especially on the inner walls of the Hollow stones put on and attached.

Mit dieser Erfindung werden weitreichende Vorteile erreicht. Insbesondere erhält man eine bessere Wärmeisolation, man spart Baustoff, insbesondere Zement, die erfindungsgemäßen Bauelemente sind auch weniger zerbrechlich. Die erfindungsgemäßen Konstruktionselemente/Bauelemente können in Form von Ziegelsteinen, Hohlsteinen, Deckenziegel als Hourdisteine für Dachböden oder Trennwände ausgebildet sein als Blöcke aus Stahlbeton, Wabenziegel etc..Far-reaching advantages are achieved with this invention. In particular, better heat insulation is obtained, construction material, in particular cement, is saved, and the components according to the invention are also less fragile. The construction elements according to the invention can be designed in the form of bricks, hollow stones, ceiling tiles as hour stone for attics or partitions as blocks made of reinforced concrete, honeycomb bricks etc.

Vorzugsweise haben die Silikonplatten eine soche Steifig­leit und werden mit solchem Druck aufgebracht, daß das Slikonmaterial um ein paar Millimeter in die Hohlräume der Bausteine eindringt. Beim Ausschäumen mit Styropor erhält man also jeweils eine Einwölbung, d.h. der Styropor­schaum tritt um einige Millimeter unter die Stirnseiten des Steins zurück. Diese Einwölbungen werden beim Ver­mauern mit Mörtel ausgefüllt, so daß sich der Mörtel gut mit den Steinen verzahnt, damit wird die Festigkeit der Mauer erhöht.The silicone plates preferably have such stiffness and are applied with such pressure that the silicone material penetrates into the cavities of the building blocks by a few millimeters. When foaming with polystyrene, you get a bulge, i.e. the styrofoam foam recedes a few millimeters below the face of the stone. These vaults are filled with mortar during bricking so that the mortar interlocks well with the stones, thus increasing the strength of the wall.

Derartige Bauelemente können mit bekannten mechanischen Hilfsmitteln bzw. automatisch hergestellt werden, mittels üblicher Greifer werden die Elemente stapelweise bzw. reihen­weise gehandhabt. Aus einem Dosiertrichter läßt man die ungeschäumten Styropor­perlen in die Löcher fließen; das überflüssige Material wird außen abgenommen und von neuem in den Kreislaut eingeleitet. Wenn die zweite Silikon-Schicht oben aufgebracht ist, inji­ziert man die Hitze mittels Wasserdampf von einer oder von beiden Seiten, also von oben und/oder von unten dieser Anordnung. Der mit Druck außen aufgebrachte Wasserdampf tritt durch das perforierte Silikon-Abdeckmaterial in das Innere der Steine, wodurch die Styroporperlen aufgeschäumt werden, insbesondere aufgrund des in ihnen enthaltenen Penthans (als Treibmittel). Der Schaum füllt das gesamte Hohlvolumen aus.Components of this type can be produced using known mechanical aids or automatically, and the elements are handled in stacks or rows by means of conventional grippers. The unfoamed polystyrene beads are allowed to flow into the holes from a metering funnel; the superfluous material is removed from the outside and reintroduced into the circular sound. When the second silicone layer is applied at the top, the heat is injected by means of water vapor from one or both sides, that is to say from the top and / or bottom of this arrangement. The water vapor, which is applied externally with pressure, passes through the perforated silicone covering material into the interior of the stones, as a result of which the polystyrene beads are foamed, in particular due to the pentane contained in them (as a blowing agent). The foam fills the entire hollow volume.

Auf der beigefügten Zeichnung wird die Erfindung nochmals erläutert:

  • Fig. 1 zeigt ein erfindungsgemäßes Bauelement in Draufsicht.
  • Fig. 2 zeigt schematisch eine Anordnung zur Durchführung des Verfahrens Gemäß der Erfindung.
The invention is explained again on the accompanying drawing:
  • 1 shows a top view of a component according to the invention.
  • Fig. 2 shows schematically an arrangement for performing the method according to the invention.

Gemäß Fig. 1 sind die Hohlräume C eines Vielkammer-Hohl-­blocksteins A mit Styriporschaum ausgeschäumt.1, the cavities C of a multi-chamber hollow block A are filled with Styripor foam.

Gemäß Fig.2 ist eine Reihe von Hohlsteinen, beispielsweise gemäß Fig. 1, nebeneinander auf einer Platte B1 aus Silikon­material aufgereiht. Die Silikonplatte ist fein perforiert und hat eine gewisse Plastizität. Die Hohlräume sind dabei vertikal angeordnet. In die Hohl­räume wird eine ausreichende Menge Polystyrolkörner (Styropor) eingefüllt. Sodann wird eine eben solche Platte aus Silikon­material B2 oben auf die Reihe von Hohlsteinen aufgelegt. Das Material und der Druck der Abdeckplatten B1, B2 ist derart, daß das Silikonmaterial um einige Millimeter in die Hohlräume eindringt. Beim Ausschäumen erhält man somit Vertiefungen oder Einwölbungen - für die bessere Verzahnung mit dem Mörtel beim Mauern. Von oben oder von oben und wird Wasserdampf (Pfeile V) aufgebracht. Der Wasserdampf dringt durch die perforierten Platten B1, B2 hindurch in das Innere; die Wärmeeinwirkung schäumt das Polystyrol, so daß der ge­samte Hohlraum ausgefüllt wird, wobei das geschäumte Poly­styrol fest an den Wandungen der Steine haftet.According to FIG. 2, a row of hollow stones, for example according to FIG. 1, is lined up next to one another on a plate B1 made of silicone material. The silicone plate is finely perforated and has a certain plasticity. The cavities are arranged vertically. A sufficient amount of polystyrene grains (polystyrene) is filled into the cavities. Then such a plate made of silicone material B2 is placed on top of the row of hollow stones. The material and the pressure of the cover plates B1, B2 is such that the silicone material penetrates the cavities by a few millimeters. When foaming, recesses or concavities are obtained - for better interlocking with the mortar when bricking. From above or from above and water vapor (arrows V) is applied. The water vapor penetrates through the perforated plates B1, B2 into the interior; the action of heat foams the polystyrene so that the entire cavity is filled, the foamed polystyrene firmly adhering to the walls of the stones.
