Description
Bauelement des Sandwichtyps sowie Verfahren zu dessen HerstellungComponent of the sandwich type and process for its manufacture
Die Erfindung betrifft ein Bauelement des Sandwichtyps wie z.B. ein Wandelement für Aufbau von grossen Baukonstruktionen, und mit zwei Aussenschichten aus verhältnismässig dichtem, vorzugsweise feuerhemmendem Material, und mindestens einer Kernschicht aus aufgeblähtem Material, vorzugsweise erhärtetem Kunststoffschaum.The invention relates to a sandwich type building element such as a Wall element for the construction of large building structures, and with two outer layers made of relatively dense, preferably fire-retardant material, and at least a core layer made of inflated material, preferably hardened plastic foam.
Ein Bauelement dieser Art mit zwei Aussenschichten und einer Kernschicht aus aufgeschäumtem Kunststoff ist bekannt, wobei die Aussenschichten durch einen über die Ränder der Aussenschichten greifenden Rahmen mechanisch voneinander getrennt gehalten werden. Dieser Rahmen weist der Bauelementmitte zugekehrte Spuren zur Aufnahme einer Kupplungsvorrichtung auf, durch die sich das Bauelement mit einem zweiten entsprechenden Bauelement verkoppeln lässt. Dieses Bauelement ist aber aufgrund des speziellen Rahmens verhältnismässig teuer, und der Rahmen bildet eine Kältebrücke zwischen den beiden Aussenschichten des Bauelements.A component of this type with two outer layers and one core layer from foamed plastic is known, the outer layers by a Mechanically separated frames that extend over the edges of the outer layers being held. This frame has tracks facing the middle of the component for recording a coupling device through which the component with one second corresponding component can be coupled. However, this component is due the special frame relatively expensive, and the frame forms a cold bridge between the two outer layers of the component.
Der Erfindung liegt die Aufgabe zugrunde, ein Bauelement der obigen Art zu schaffen, das besonders einfach aufgebaut und leicht herzustellen ist, und das ferner keine Kältebrücken zwischen seinen Aussenschichten bildet.The invention is based on the object of a component of the above To create kind that is particularly simple in structure and easy to manufacture, and which also does not form cold bridges between its outer layers.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Kernschicht nahe am Rand des Bauelements durch einen umlaufenden profilierten Randkörper aus hochisolierendem, schwer anzündbarem, erhärtetem Kunststoffschaum mit einem hauptsächlich trapezförmigen Querschnitt abgegrenzt ist, wobei die kurze Seite des Trapezes der Kernschicht zugekehrt ist, während die schrägen Seiten den Aussenschichten derart zugekehrt sind, dass die den schrägen Trapezseiten entsprechenden Flächen des Randkörpers zusammen mit den Aussenschichten einen keilförmigen Spalt beiderseits des Randkörpers abgrenzen, welche Spalte, wenn sie mit Kernmaterial gefüllt sind, den Randkörper an die Aussenschichten anleimen. Hierdurch wird ein sehr einfacher Aufbau erreicht. Da der Randkörper aus hartem Kunststoff ist, entstehen keine Kältebrücken zwischen den Aussenschichten des Elements. Der Randkörper klebt, aufgrund des Leimens an den erwähnten keilförmigen Spalten, an den Aussenschichten gut fest.This object is achieved according to the invention in that the core layer close to the edge of the component by a circumferential profiled edge body highly insulating, hard to ignite, hardened plastic foam with a mainly trapezoidal cross-section is delimited, the short side of the trapezoid being the Core layer is facing, while the sloping sides of the outer layers on the other hand, the surfaces of the edge body corresponding to the inclined trapezoidal sides together with the outer layers a wedge-shaped gap on both sides of the edge body delimit which gaps, when filled with core material, form the edge body glue to the outer layers. This results in a very simple structure. Since the edge body is made of hard plastic, there are no cold bridges between the outer layers of the element. The edge body sticks due to the gluing the wedge-shaped gaps mentioned, firmly attached to the outer layers.
Gemäss der Erfindung kann die freie Fläche des Randkörpers eine längs verlaufende Versenkung zur Aufnahme tragender Säulen oder Balken in der Baukonstruktion aufweisen. In dieser Weise wird erreicht, dass das Element sich zu einer tragenden Konstruktion befestigen lässt, ohne dass dies sichtbar ist. Tragende Säulen und/oder Balken lassen sich auch zwischen zwei aneinander angrenzenden Bauelementen verstehen.According to the invention, the free surface of the edge body can be longitudinal running countersink to accommodate supporting columns or beams in the building structure exhibit. In this way it is achieved that the element becomes a load-bearing The construction can be attached without this being visible. Supporting pillars and / or Bars can also be understood between two adjoining components.
Ausserdem kann, gemäss der Erfindung, der Randkörper mindestens eine Aussparung zur Aufnahme von Verbindungsleisten aufweisen. Hierdurch lassen sich zwei nebeneinander angeordnete Bauelemente leicht zusammenfügen, ohne dass die Verbindungsvorrichtungep sichtbar sind, da die obigen Leisten teils in eine Aussparung in einem Bauelement und teils in eine gegenüberliegende Aussparung in einem benachbarten entsprechend ausgebildeten Bauelement hineinragen können.In addition, according to the invention, the edge body can have at least one Have recess for receiving connecting strips. This allows Easily join two components arranged next to one another without the connecting device are visible, because the above strips are partly in a recess in a component and partly in an opposite recess in an adjacent one formed accordingly Can protrude component.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung des Bauelements gemäss der Erfindung, und dieses Verfahren ist dadurch gekennzeichnet, dass ein Formkasten angewendet wird, der hauptsächlich wie das Bauelement geformt ist, und in dem die beiden Aussenschichten mit gegenseitigem Abstand derart angeordnet werden, dass ein profilierter, vorzugsweise hauptsächlich trapezförmiger Randkörper zwischen den Aussenschichten an deren Rändern angeordnet wird, wonach ein klebendes Kernmaterial in den Raum zwischen den Aussenschichten hineingespritzt und zum Aufschäumen gebracht wird, wobei es in die keilförmigen Spalte zwischen Aussenschichten und Randkörper hinausdrängt und dadurch den Randkörper an die Aussenschichten klebt. Dieses Verfahren ist besonders einfach, da das expandierende Kernmaterial den Randkörper spontan zwischen die Aussenschichten in korrekte Stellung presst und ihn darauf effekt festklebt. Kältebrücken am Randkörper werden auch hier vermieden.The invention also relates to a method for producing the component according to the invention, and this method is characterized in that a Mold box is applied, which is mainly shaped like the component, and in which the two outer layers are arranged at a mutual distance in such a way that that a profiled, preferably mainly trapezoidal edge body between the outer layers is arranged at their edges, after which an adhesive core material injected into the space between the outer layers and caused to foam being, it being in the wedge-shaped gap between the outer layers and the edge body pushes out and thereby sticks the edge body to the outer layers. This method is particularly simple, since the expanding core material spontaneously touches the edge body presses between the outer layers in the correct position and glues it onto it effectively. Cold bridges on the edge body are also avoided here.
Fernerhin kann, gemäss der Erfindung, das angewendete Kernmaterial einer Art sein, das zu einem Volumen aufschäumt, das 25 bis 30 Mal dem Anfangsvolumen entspricht. Hierdurch presst das Kernmaterial besonders effektiv auf den Randkörper und füllt dadurch auch die keilförmigen Spalte effektiv aus.Furthermore, according to the invention, the core material used be of a type that foams up to a volume 25 to 30 times the initial volume is equivalent to. As a result, the core material presses particularly effectively on the edge body and thereby also effectively fills the wedge-shaped gaps.
Ausserdem kann, gemäss der Erfindung, das angewendete Kernmaterial Mineralwolle sein, der an ihren den Aussenschichten bzw. dem Randkörper zugekehrten Seiten eine Schicht von aufschäumbarem Leim, vorzugsweise des Zwei-Komponenten-Typs, aufgetragen worden ist, wobei das Bauelement besonders feuerhemmend wird.In addition, according to the invention, the core material used Be mineral wool, the one facing the outer layers or the edge body Sides a layer of foamable glue, preferably of the two-component type, has been applied, the component being particularly fire-retardant.
Schliesslich gemäss der Erfindung können die angewendeten Aussenschichten aus Metall, Holz wie z.B. Sperholz, Kunststoff, gegebenenfalls armiertem Kunststoff, Steinmaterialien oder Asbestzement hergestellt sein, wobei die Feuerheständigkeit auch erhöht wird.Finally, according to the invention, the outer layers used can made of metal, wood such as plywood, plastic, possibly reinforced plastic, Stone materials or asbestos cement can be made with fire resistance is also increased.

Schliesslich wird das Bauelement dem Formkasten 21 entnommen.Fig. 3 shows an open molding box 21 for the production of a component according to the invention. First, an outer layer such as an asbestos-cement board placed in it, see the dotting in ib. On this outer layer and near the The edge body or bodies 3 are then arranged on walls of the molding box. A part such a body is also indicated by dotted lines. On this one or this one Edge body 3 is then arranged the second outer layer la, which is also dotted is indicated. Thereafter, the molding box is closed by a lid, not shown. A core material in the form of a foamed is then through an opening 23 in the molding box Plastic, preferably of the two-component type, injected into it. It can for example modified two-component polyurethane. This is expanding and becomes hard under high pressure. It is best if the core material of the species that foams to a volume 25 to 30 times the initial volume. During the foaming, the core material pushes into the column 6a and 6b, cf. Fig. 1, in addition, it the edge body 3 to the outer layers la and lb very much effectively sticks. There are no special external facilities for It is necessary to hold the outer layers 1 a and 1 b together. Finally the component becomes taken from the molding box 21.
An Stelle aufgeschäumten Kunststoffes kann das Kernmaterial auch Mineralwolle sein, der auf ihren den Aussenschichten bzw. dem Randkörper zugekehrten Seiten eine Schicht von aufschäumbarem Leim aufgetragen worden ist. Dieser Leim klebt dann den Randkörper und die Mineralwolle effektiv an die Aussenschichten fest, ohne dass Kältebrücken entstehen. Das Bauelement kann entweder gross oder klein sein. Es eignet sich beispielsweise gut als Wandelement in Typenhäusern, wobei es eine ganze Wand bilden kann. Es lässt sich aber auch in Decken und Böden anwenden.Instead of foamed plastic, the core material can also be mineral wool be, the one on their sides facing the outer layers or the edge body Layer of foamable glue has been applied. This glue then sticks the Edge body and the mineral wool effectively adhere to the outer layers without Cold bridges arise. The component can either be large or small be. It is, for example, well suited as a wall element in type houses, where there is a can form whole wall. But it can also be used in ceilings and floors.
Die Erfindung lässt sich in vielen Weisen variieren, ohne dass man hierdurch von ihrer Idee abweicht. Die Randkörper lassen sich beispielsweise aus vielen Typen von aufgeschäumtem Kunststoff herstellen. Am besten werden sie in besonders konstruierten Aluminiumformen gegossen. Zwei Randkörper lassen sich beispielsweise auf einmal giessen. Nach dem Abformen und dem Erhärten wird der Randkörper dann durchgeschnitten, wobei zwei Stücke der erwünschten Randkörper entstehen.The invention can be varied in many ways without one thereby deviates from their idea. The edge bodies can be omitted, for example manufacture many types of foamed plastic. They are best in special constructed aluminum molds. Two edge bodies can be, for example pour at once. After the molding and hardening, the edge body is then cut through, creating two pieces of the desired edge body.
Wie in Fig. 2 dargestellt, lassen die Bauelemente sich durch eine Leimfuge 25 zusammenfügen.As shown in Fig. 2, the components can be through a Put glue joint 25 together.
