Description

Die Erfindung betrifft Verbundbauteile aus einem Metalldrahtgitter und einer Kunststoffabdeckung, die an den Kreuzungspunkten des Metalldrahtgitters Über Verbindungsschellen mit diesem starr verbunden ist. Verbundbauteile dieser Art sind aus der DE-PS 22 47 358 bekant. Sie erhalten ihre statische Steifigkeit dadurch, daß sie tonnenförmig gewölbt sind und die plattenförmige Kunststoffabdeckung im Abstand von dem Metalldrahtgitter ageordnet ist. Bei der Belastung der bekannten Verbundbauteile treten Drehmomente an den Verbindungsstellen zwischen den Kreuzungspunkten des Metalldrahtgitters und der Kunststoffab deckung auf. Diese Momente sind umso größer, je größer der Abstand zwischen dem Metalldrahtgitter und der Kunststoffabdeckung ist. Um den Bruch der Kunstoff abdeckung a den Verbindungspunkten zu vemeiden, müssen die Verbindungsstellen möglichst momentenfrei auf den Kreuzungspunkten des Metalldrahtgitters agebracht werden, was namentlich dann wenn mit den Verbundbauelementen größere Flächen überdeckt werden sollen, zu einer aufwendigen Gestaltung der Verbindungsschellen führt.The invention relates to composite components made of a metal wire mesh and a plastic cover which is rigidly connected to the metal wire mesh at the crossing points by means of connecting clamps. Composite components of this type are known from DE-PS 22 47 358. They obtain their static rigidity from the fact that they are barrel-shaped and the plate-shaped plastic cover is arranged at a distance from the metal wire mesh. When loading the known composite components, torques occur at the junctures between the intersections of the metal wire mesh and the plastic cover. The greater the distance between the metal wire mesh and the plastic cover, the greater these moments. In order to avoid the breakage of the plastic cover a the connection points, the connection points must be installed on the crossing points of the metal wire mesh as free of torque as possible, which leads to a complex design of the connection clamps, especially when larger areas are to be covered with the composite components.

Ein Verbundbauteil bei dem beide Seiten des Traggitters mit Deckflächen ausgerüstet sind ist in der US-PS 3 672 022 beschrieben. Die Deckflächen werden an dem Traggitter durch Schweißen, durch Löten oder durch Verkleben befestigt.A composite component in which both sides of the support grid are equipped with cover surfaces is described in US Pat. No. 3,672,022. The cover surfaces are attached to the support grid by welding, soldering or gluing.

Die beiden oben anegebenen den Stand der Technik ausweisenden Patentschrifte beschreiben Verbundbauelemente aus einem Tragitter mit einseitiger bzw.beidseitiger Bedeckung von gleicher Größe. Die einzelnmen Verbundbauelemente können dann nur durch geeignete, aufwendige Hilfskonstruktion en zu einem größeren Bauteil zusammengesetzt werden.The two state of the art patent documents cited above describe composite components made of a trellis with one-sided or two-sided covering of the same size. The individual composite components can then only be put together to form a larger component using suitable, complex auxiliary structures.

Der Erfindung liegt die Aufgabe zugrunde, die bekannten Verbundbauteile bezüglich ihrer Steifigkeit zu verbessern ohne daß an den Verbindungsstelen zwischen dem Metalldrahtgitter und der Kunststoffabdeckung Drehmomente auf treten oder aufwendige Verbindungsschellen zur Aufnahme solcher Drehmomente erforderlich werden. Weiterhin sollen die Verbundbaiteile in einfacher Weise aus kleineren Elementen zusammengesetzt werden ohne daß die Einzelelemente verbindende Hilfskonstruktionen erforderlich werden. Die Aufgabe wird da-durch gelöst, daß das Traggitter beidseitig mit je einer Kunsstoffabdeckung starr verbunden ist, und daß das Verbundbauteil aus aneinandergerihten Einzelementen, die kleiner als das Verbundbauteil selbst sid, zusammengestzt ist, wobei die Stoßstellen zwischen den Einzelementen in der Gesamtfläcke des Verbundbauteils versetzt gegeneinander angeordnet sindThe invention has for its object to improve the known composite components in terms of their rigidity without that torques occur at the connecting steles between the metal wire mesh and the plastic cover or complex connection clamps are required to accommodate such torques. Furthermore, the composite components should be assembled in a simple manner from smaller elements without the need for auxiliary structures connecting the individual elements. The object is achieved in that the support grid is rigidly connected on both sides to a plastic cover, and that the composite component is made up of individual elements arranged side by side, which are smaller than the composite component itself, with the joints between the individual elements in the overall area of the composite component are staggered

Dadurch ist es jetzt möglich, Verbundbauteile von nahezu beliebiger Größ aus Einzelelementen aufzubauen, die kleiner als das Verbundbauteil selbs sind. Dieses Bauteil kann als Ganzes Zug-und Schubkräfte aufnehmen und übertragen obwohl weder in den Kunststoffabdeckungen noch in den Traggittern eine durchgehende kraftschlüssige Verbindung besteht. Das wir dadurch möglich, daß die beidseitig starr mit Einzelelementen des Traggitters verbundenen Kunststoffdeckflächen versetzt gegen die Elemente des Traggitters angeordnet sind.This makes it possible to build composite components of almost any size from individual elements that are smaller than the composite component itself. This component as a whole can absorb and transmit tensile and shear forces even though there is no continuous positive connection neither in the plastic covers nor in the supporting grids. This is made possible by the fact that the plastic cover surfaces rigidly connected on both sides to individual elements of the support grid are arranged offset against the elements of the support grid.

Die neuen Verbundbauteile sind nach dem Prinzip des. Gitterträgers, jedoch in flächiger Ausführung, aufgebaut. Zwei Kunststoffabdeckungen (1) und (2) bilden Ober-und Untergurt des Gittertragwerks. Das aus Mefitall drähten bzw. stäben gebildete Traggitter (3) übernimmt die Funktion des stützenden Steges zwischen Ober-und Untergurt. Im Falle geringer Belastung oder hoher Eigensteifigkeit des Traggitters kann dieses flach ausgebildet sein wie z. B. eine herkömmiiche Baustahlmatte. Wenn eine höhere statische Steifigkeit gefordert wird, wird ein dreidinensionales Gitterwerk verwendet. In diesem sind die Metalldrähte bzw. stäbe etwa senkrecht zur Ebene der Kunststoffabdeckungen periodisch gebogen und an den Scheitelpunkten (4) mit der jeweils anliegenden Kunststoffabdeckung starr verbunden. Im Regelfall besteht das Gitter aus rechtwinklig zueinander verlaufenden Metallstäben. Um die erforderliche Steifigkeit zu erreichen, kann es genügen,-die Metallstäbe in einer der Gitterrichtungen in beschriebenen Sinne periodisch zu biegen. Vorzugsweise sind die Metallstäbe in beiden Gitterrichtungen in dieser Weise gebogen. Durch die periodische Biegung wird der Abstand zwischen dem Ober-und Untergurt des Gittertragwerks vergrößert und dadurch seine statische Steifigkeit erhöht. Um Drehmomente, die auf die kunststoffabdeckungen einwirken, weitgehend auszuschließen, werden die Kunststoffabdeckungen möglichst dicht an den Metall stäbe; . den Scheitelpunkten der Metallstäbe

Figure imgb0001
. 3 zeigt eine Detaillösung, bei u- t se Verbindung mit ein em geringen Abstand zwischen der Kunststoffabdeckung und dem Metallstabgitter verwirklicht wird. Vorzugsweise sind benachbarte, in gleicher Richtung verlaufende Metallstäbe jeweils gegenläufig gekrümmt, so daß inre Scheitelpunkte jeweils um eine halbe Periodenlänge P gegeneinader versetzt sind. Vorzugsweise sind die Metallstäbe in beiden Gitterrichtungen in dieser Weise gegenläufig gekrümmt und an den jeweiligen Scheitelpunkten zu Kreuzungspunkten miteinander verbunden. Bei dieser Gestaltung folgen bei jedem Metallstab jeweils ein hochliegender und ein tiefliegender Kreuzungspunkt aufeinander. Die Metallstäbe können an den Kreuzungspunkten verschweißt sein. Zweckmäßiger ist eine Verbindungsschelle (10), die gleichzeitig zur Verbindung mit der Kunststoffabdeckung dient.The new composite components are based on the principle of the lattice girder, but in a flat design. Two plastic covers (1) and (2) form the upper and lower chord of the lattice structure. The supporting grid (3) formed from wire or rod takes over the function of the supporting web between the upper and lower chord. In the case of low load or high rigidity of the support grid, this can be flat such. B. a conventional structural steel mat. If a higher static rigidity is required, a three-dimensional lattice is used. In this the metal wires or rods are periodically bent approximately perpendicular to the plane of the plastic covers and rigidly connected at the apexes (4) to the plastic cover in each case. As a rule, the grille consists of metal bars running at right angles to one another. In order to achieve the required rigidity, it may be sufficient to periodically bend the metal bars in one of the lattice directions in the sense described. The metal rods are preferably bent in this way in both grating directions. The periodic bending increases the distance between the upper and lower chord of the lattice structure and thereby increases its static rigidity. To largely exclude torques that act on the plastic covers, the plastic covers are as close as possible to the metal rods; . the vertices of the metal bars
Figure imgb0001
. 3 shows a detailed solution in which the connection is realized with a small distance between the plastic cover and the metal bar grille. Adjacent metal rods running in the same direction are preferably each curved in opposite directions, so that their apexes are offset by half a period length P from one another. The metal rods are preferably in opposite directions in both grating directions curved and connected to each other at the respective vertices to intersection points. With this design, a high and a low-lying crossing point follow each other for each metal rod. The metal bars can be welded at the crossing points. A connection clamp (10), which also serves for connection to the plastic cover, is more expedient.

Vorzugsweise werden die Metallstäbe etwa in Form einer Sinuskurve gebogen, wie in Fig. 1 dargestellt. Sie können jedoch auch zickzacktrapez-oder rechteckförmig mit kleinen Krümmugsradien an den Scheitelpunkten gebogen sein; vgl. Fig. 2.The metal rods are preferably bent approximately in the form of a sine curve, as shown in FIG. 1. However, they can also be curved in a zigzag trapezoidal or rectangular shape with small radii of curvature at the vertices; see. Fig. 2.

Im Falle eines erfindungsgemäßen Verbundbauteils von gleichförnger Gesamtdicke ist die Biegung der Metallstäbe in jeder Periode gleich hoch und vorzugsweise jede Periode P gleich lang. Diese Gestaltungsweise eiget sich für große ebene oder tonnenförmig gewölbte Verbundbau teile. Für frei vorkragende ebene oder gewölbte Dachflächen kann eine schwache Neigung der Kunststoffabdeckungen (5) und (5 ') gegeneinader vorteilhafter sein. In diesem Falle können die Längen der einzelnen Biegurgsperioden (P1. P2, P3 ...) der Metallstäbe mit abnehmender Gesamtdicke ebenfalls kleiner werden, wie in Fig. 2 dargestellt.In the case of a composite component according to the invention of the same overall thickness, the bending of the metal bars is the same in every period and preferably each period P is of the same length. This design is suitable for large flat or barrel-shaped arched composite parts. For freely projecting flat or curved roof surfaces, a slight inclination of the plastic covers (5) and (5 ') can be more advantageous. In this case, the lengths of the individual bending cycle periods (P 1. P 2 , P 3 ...) of the metal bars can also become smaller with decreasing overall thickness, as shown in FIG. 2.

Die neuen Verbundbauteile haben nicht nur eine erhöhte statische Steifigkeit, sondern gewähren durch das Vorhandensein von zwei im Abstand angeordneten Kunststoffabdeckungen gleichzeitig eine erhöhte Wärme-und Schalldämmung. Sie eignen sich daher zur Errichtung von selbst tragenden, großflächigen Bauwerken oder Teilen davon, wie Lichtwärden Schalls chut zwänden, Lichtdäche rn Gewächshäusern, Schallschutzturneln für Straßen und Eisenbahren, Fabrikhallen usw. Bei der Errichtung großflächiger Bauteile dieser Art werden sowohl die Kunststoffabdeckungen als auch die Metallstäbe aus kleinen Einzelelementen an einandergereiht. Die Steifigkeit und Tragfähigkeit des gesamten Bauteils wird dadurch nicht beeinträchtigt, vorausgesetzt, daß die Stoßstellen zwischen den einzelnen Teilelementen in der Gesamtfläche des Bauteils versetzt gegeneinander angeordnet sind. In allgemeinen ist es nicht erforderlich, die Elemente so miteinander zu verbinden, daß die Verbindungsstelle auf Zug beansprucht werden kann. So können die Enden von aneinander stoßenden Meatallstäben durch lose aufgesteckte Rohrhülsen miteinander verbunden werden. Die Ränder von benachbarten Kunststoffabdeckelementen können durch geeignete Klemmpfirofile verbunden werden.The new composite components not only have an increased static rigidity, but at the same time ensure increased thermal and acoustic insulation due to the presence of two plastic covers arranged at a distance. They are therefore suitable for the erection of self-supporting, large-area structures or parts thereof, such as light walls, noise insulation, light roofs in greenhouses, soundproofing gates for streets and iron stretchers, factory halls, etc. When building large-area components of this type, both the plastic covers and the metal rods are used made up of small individual elements. The rigidity and load-bearing capacity of the entire component is not adversely affected, provided that the joints between the individual sub-elements in the total surface of the component are offset from one another. In general, it is not necessary to connect the elements to one another in such a way that the connection point can be subjected to tension. The ends of butting metal bars can be connected to each other by loosely attached tubular sleeves. The edges of neighboring plastic cover elements can be connected using suitable clamp profiles.

Die Kunststoffabdeckungen und die Metallstäbe müssen den aufzunehmenden Verkehrslasten entsprechend dimensioniert sein. Das Traggitter besteht vorzugsweise aus Stahlstäben, jedoch können auch Stäbe aus Alumium oder anderen Metallen Verwendung finden. Je nach der Größe des Gesamtbauwerks und den auftretenden Verkehrslasten kommen Stahlstäbe von beispielsweise 5 20 mm Durchmesser in Betracht. Die Stahlstäbe werden vorzugsweise verzinkt oder korrosionsfest beschichtet.The plastic covers and the metal bars must be dimensioned according to the traffic loads to be absorbed. The support grid is preferably made of steel bars, but bars made of aluminum or other metals can also be used. Depending on the size of the overall structure and the traffic loads that occur, steel bars of, for example, 5 20 mm in diameter can be considered. The steel rods are preferably galvanized or coated in a corrosion-resistant manner.

Die Verbindungsschellen für die.Kreuzungspunkte des Traggitters bestehen vorzugsweise ebenfalls aus Metall und können beispielsweise durch Druckguß aus Aluminium hergestellt sein. Zweckmäßig ist eine Gestaltung gemäß Fig. 3, bei der die Mefitallstäbe (6), (7) in kreuzweise angeordnete Schlitze (8) eingeschoben und durch einen Gewindering (9) unverrückbar verklemmt sind. Die Kunststoffabdeckung (1) wird an der gleichen Verbindungs schelle (10) befestigt. Zu diesem Zweck trägt sie einen Gewindeschaft (11), der durch eine entsprechende Bohrung in der Kunststoffabdeckung führt. Eine starre und zugleich Wasserdichte Befestigung der Kunststoffabdeckung wird erreicht, wenn sie mit Dichtungsscheiben (12), (13) aus elastischem Material, einer Klemmscheibe (14) und einer Hutmutter (15) befestigt wird. Gegebenenfalls kan auch der Gewindeschaft (11) mit einem elastischen Material überzogen sein .The connecting clamps for the crossing points of the supporting grid are preferably also made of metal and can be made, for example, by die-casting from aluminum. A design according to FIG. 3 is expedient, in which the metal rods (6), (7) are inserted into crosswise arranged slots (8) and are immovably clamped by a threaded ring (9). The plastic cover (1) is fastened to the same connection clamp (10). For this purpose, it carries a threaded shaft (11) which leads through a corresponding hole in the plastic cover. A rigid and at the same time watertight fastening of the plastic cover is achieved if it is fastened with sealing washers (12), (13) made of elastic material, a clamping washer (14) and a cap nut (15). If necessary, the threaded shaft (11) can also be covered with an elastic material.

Als Kunststoffabdeckung eignen sich Hohlkamertafeln oder Vollprofiltafeln, die flach oder gewellt sein können. Hohlkamertafeln beispielsweise extrudierte Stegdoppelplatten haben den Vorteil einer hohen Eigensteifigkeit bei geringem Gewicht. Als Kunststoffe eignen sich Poly carbonate, Polymethylmethacrylat Polyvinylchlorid, glasfaserverstärkte Polyester oder Polyolefine. Bei Verwendung von Hohlkammerprofilen werden extrudierte Stegdoppelplatten aus Polycarbonat bevorzugt. Vollprofilplatten können in einer Stärke von beispielsweise 2 8 mm eingesetzt werden. Geeignete Hohlkammerprofile können Dicken von 8 40 mm haben. Die obere und die untere Abdeckung können aus gleichartigem oder verschiedenem Kunststoffmaterial bestehen.Hollow camera panels or solid profile panels, which can be flat or corrugated, are suitable as plastic covers. Hollow camera panels, for example, extruded double-wall sheets have the advantage of high inherent rigidity with low weight. Suitable plastics are poly carbonates, polymethyl methacrylate, polyvinyl chloride, glass fiber reinforced polyesters or polyolefins. When using hollow chamber profiles, extruded double-wall sheets made of polycarbonate are preferred. Solid profile panels can be used in a thickness of, for example, 2 8 mm. Suitable hollow chamber profiles can have a thickness of 8 40 mm. The top and bottom covers can be made of the same or different plastic material.
