Description

Die Erfindung betrifft ein Bauelement zur Erstellung von Grundelementen bei Baukonstruktionen mit der Grundform eines flachen, rechteckigen Quaders, in dessen Grundfläche eine Nut in Form eines Trapezes vorgesehen ist, dessen längere Seite den Nutboden bildet, und der wenigstens eine sich entlang einer seiner kurzen Kanten erstreckende Ausnehmung aufweist.The invention relates to a component for creating basic elements in building structures with the basic shape of a flat, rectangular cuboid, in the base of which a groove in the form of a trapezoid is provided, the longer side of which forms the groove bottom, and the at least one extending along one of its short edges Has recess.

Aus der FR-A-2 370 142 ist ein Bauelement als Bestandteil einer Deckenkonstruktion bekannt, dessen äußerer Umriß den tragenden Elementen, mit denen es zusammenwirkt, genau angepaßt ist. Sämtliche gegeneinander abgewinkelte Flächen des Bauelements haben dabei zueinander rechte oder deutlich stumpfe Winkel. Die durch Anpassung an die benachbarten Elemente vorgegebenen Vorsprünge und Ausnehmungen unterliegen keinem einheitlichen Gestaltungsprinzip. Das bekannte Bauelement kann deshalb immer nur für eine einzige, bei der Gestaltung seiner äußeren Form zu berücksichtende Baukonstruktion verwendet werden. Außerdem ist seine Außenform kompliziert, empfindlich gegen Transportbeschädigungen und schwierig herzustellen.From FR-A-2 370 142 a component is known as part of a ceiling construction, the outer contour of which is precisely adapted to the load-bearing elements with which it interacts. All surfaces of the component that are angled relative to one another have right angles or clearly obtuse angles to one another. The projections and recesses given by adaptation to the adjacent elements are not subject to a uniform design principle. The known component can therefore only ever be used for a single construction structure to be taken into account when designing its external shape. In addition, its outer shape is complicated, sensitive to transport damage and difficult to manufacture.

Aus der FR-A-2 441 693 ist weiterhin ein Bauelement bekannt, das auf seiner einen Oberfläche eine trapezförmige Nut sowie seitliche Ausnehmungen aufweist. Diese seitlichen Ausnehmungen befinden sich jedoch auf der gleichen Seite wie die trapezförmige Nut, so daß der Einsatzbereich dieses Bauelements sehr eingeschränkt ist. Die Ausnehmung bildet außerdem einen rechten Winkel.From FR-A-2 441 693 a component is also known which has a trapezoidal groove on one surface and lateral recesses. However, these lateral recesses are on the same side as the trapezoidal groove, so that the area of use of this component is very limited. The recess also forms a right angle.

Die der Erfindung zugrunde liegende Aufgabe besteht deshalb darin, das Bauelement der eingangs genannten Art so auszubilden, daß es bei einfacher Form, die die direkte Herstellung an der Baustelle ohne die Verwendung schwerer spezieller Maschinen ermöglicht, universell für die verschiedenstens Baukonstruktionen einsetzbar ist.The object on which the invention is based is therefore to design the component of the type mentioned at the outset in such a way that it can be used universally for a wide variety of building constructions in a simple form which enables direct manufacture at the construction site without the use of heavy special machines.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Ausnehmung auf der der Grundfläche mit der Nut gegenüberliegenden Seite vorgesehen ist und daß die beiden Flächen, welche gemeinsam die Ausnehmung bilden, einen spitzen Winkel einschließen.This object is achieved in that the recess is provided on the side opposite the base with the groove and that the two surfaces which together form the recess form an acute angle.

Das erfindungsgemäß ausgestaltete Bauelement ermöglicht nicht nur die Errichtung von Decken sondern darüber hinaus auch beispielsweise von Wänden, Pfeilern, Sturzbalken, Tragbalken und Fundamenten. Unter alleiniger Verwendung des erfindungsgemäßen Bauelements können also komplette Bauwerke errichtet werden. Aufgrund seiner äußerst einfachen konstruktiven Gestaltung ist es für eine Massenproduktion hervorragend geeignet. Infolge des Fehlens weit ausragender Teile ist das Bauelement gegenüber Stoßkräften beim Transport unempfindlich. Bei einem Deckenaufbau entsteht bei Verwendung des erfindungsgemäßen Bauelements zwischen jeweils zwei nebeneinanderliegenden Bauelementen ein sich nach oben hin verjüngender Hohlraum, der durch Tragbalken ausgefüllt werden kann. Durch die zustandekommende Hinterschneidung des Zwischenraums zwischen den einzelnen Bauelementen ergibt sich eine formschlüssige Verbindung mit den zwischengelegten Längselementen. Beim Aufbau einer horizontalen Wand unter Verwendung des erfindungsgemäßen Bauelements ergibt sich durch die schwalbenschwanzartige Verkeilung mit zwischengelegten Balken eine ausgezeichnete Stabilität des fertigen Bauwerks.The component designed according to the invention enables not only the erection of ceilings but also, for example, walls, pillars, lintel beams, supporting beams and foundations. Complete structures can thus be erected using only the component according to the invention. Due to its extremely simple structural design, it is ideally suited for mass production. Due to the lack of protruding parts, the component is insensitive to impact forces during transport. In the case of a ceiling structure, when the component according to the invention is used, a cavity which tapers towards the top is created between two adjacent components and can be filled by supporting beams. The resulting undercut of the space between the individual components results in a positive connection with the interposed longitudinal elements. When building a horizontal wall using the structural element according to the invention, the dovetail-like wedging with interposed beams results in excellent stability of the finished structure.

Vorteilhafterweise beträgt der spitze Winkel ungefähr 80°.The acute angle is advantageously approximately 80 °.

Das in Fig. 1 gezeigte Bauelement P, wie es zur Erstellung von Grundelementen bei Baukonstruktionen verwendet wird, hat die Grundform eines flachen rechteckigen Quaders, in dessen Grundfläche eine Nut 1 in Form eines Trapezes ausgespart ist, dessen längere Seite den Nutboden bildet. Längs einer der kurzen Kanten des Bauelements P erstreckt sich eine Ausnehmung 2 auf der der Grundfläche mit der Nut 1 gegenüberliegenden Seite. Die beiden Flächen, welche gemeinsam die Ausnehmung 2 bilden, schließen einen spitzen Winkel 2, der bei dem gezeigten Ausführungsbeispiel 80° beträgt. Das Bauelement P kann mit Kammern K versehen sein. Auf der der Nut 1 gegenüberliegenden Fläche kann, wie in Fig. 1 gezeigt ist, eine Wärmedämmung N aufgebracht werden, die mit einem entsprechend ausgeformten Abschnitt in die Ausnehmung 2 eingreift.The component P shown in FIG. 1, as it is used to create basic elements in building constructions, has the basic shape of a flat rectangular cuboid, in the base area of which a groove 1 in the form of a trapezoid is recessed, the longer side of which forms the groove bottom. A recess 2 extends along one of the short edges of the component P on the side opposite the base area with the groove 1. The two surfaces, which together form the recess 2, close an acute angle 2, which is 80 ° in the exemplary embodiment shown. The component P can be provided with chambers K. On the surface opposite the groove 1, as shown in FIG. 1, thermal insulation N can be applied, which engages in the recess 2 with a correspondingly shaped section.

Bei der in Fig. 2 gezeigten Deckenkonstruktion werden die Bauelemente so verwendet, daß jeweils zwei Nuten 1 einander zugewandt sind, wodurch sich ein Hohlblockelement ergibt, an dessen vier Längskanten sich die Ausnehmungen 2 befinden. Diese Hohlblockelemente werden in zwei parallelen Reihen im Abstand hintereinander so angeordnet, daß die Ausnehmungen in jeder Reihe einander zugewandt sind. Die Ausnehmungen 2 der unten liegenden Bauelemente liegen auf parallelen Deckenbalken 4 auf. In die oberen, einander zugewandten Ausnehmungen 2 greifen Tragbalken 5 ein, wobei eine schwalbenschwanzartige Verkeilung mit den entsprechend gestalteten Tragbalken 5 und den gegenüberliegenden Ausnehmungen 2 erreicht wird.In the ceiling construction shown in Fig. 2, the components are used so that two grooves 1 face each other, resulting in a hollow block element, on the four longitudinal edges of which the recesses 2 are located. These hollow block elements are arranged in two parallel rows at a distance one behind the other so that the recesses in each row face each other. The recesses 2 of the components located below lie on parallel ceiling beams 4. Support beams 5 engage in the upper, mutually facing recesses 2, wherein a dovetail-like wedging is achieved with the appropriately designed support beam 5 and the opposite recesses 2.

Bei der Ausführungsform von Fig. 3 werden unter Verwendung der Bauelemente P Vollwände hergestellt. In die einander zugewandten Ausnehmungen 2 der einandergesetzten Bauelemente P sind dabei Leisten 15 eingepaßt, an denen eine Wandverkleidung angebracht werden kann. In die Nuten 1 greifen dabei Vorsprünge eines wärmedämmenden Materials 13 oder von Gegensteinen 14 ein, die genauso wie die Bauelemente P geformt sein können.In the embodiment of FIG. 3, solid walls are produced using the components P. In the mutually facing recesses 2 of the components P placed one another strips 15 are fitted, to which a wall covering can be attached. Protrusions of a heat-insulating material 13 or of counter-stones 14 engage in the grooves 1, which can be shaped in the same way as the components P.

Bei der Hohlwandkonstruktion von Fig. 4 sind die Bauelemente P auf der Raumseite wie bei Fig. 3 angeordnet, wobei anstelle der eine Wandverkleidung tragenden Latten 15 auch Wandverkleidungsplatten 16 über die Ausnehmungen 2 gehalten werden können. Zwischen einer durch Distanzträger auf Abstand gehaltenen Außenwand, die aus Bauelementen P zusammengesetzt sein kann, in deren Ausnehmungen Wärmedämmstreifen 22 eingesetzt sein können und die auf ihrer Außenseite 19 mit Ziegeln 24 und Verputz 23 versehen werden können, ist ein wärmedämmendes Füllmaterial 20 eingebracht.4, the components P are arranged on the room side as in FIG. 3, it being possible for wall cladding panels 16 to be held over the recesses 2 instead of the slats 15 carrying a wall cladding. A heat-insulating filler 20 is introduced between an outer wall which is kept at a distance by spacers and which can be composed of components P, in whose recesses thermal insulation strips 22 can be inserted and which can be provided with bricks 24 and plaster 23 on its outer side 19.

Bei der in Fig. 5 gezeigten Ausführungsform sind die Bauelemente P wie in Fig. 2 einander gegenüberliegend in Reihen angeordnet, bei denen die Ausnehmungen 2 einander zugewandt sind. Zwischen den Reihen von Bauelementen P sind Keilsteine 3 eingesetzt, die in die Ausnehmungen 2 deckend eingreifen. Die Nuten 1 zwischen den Bauelementen P können dabei einen Lüftungskanal 25 oder einen Rauchgaskanal 27 bilden. Zwischen den Keilsteinen kann ein Kanal 26 für die Belüftung vorgesehen werden.In the embodiment shown in FIG. 5, the components P are arranged opposite one another in rows, as in FIG. 2, in which the recesses 2 face one another. Wedge stones 3 are inserted between the rows of components P, which engage in the recesses 2 in a covering manner. The grooves 1 between the components P can form a ventilation duct 25 or a flue gas duct 27. A channel 26 for ventilation can be provided between the wedge stones.
