Jede Drahtgittermatte 1 bzw. 2 besteht aus mehreren Längsdrähten 3, 4 und aus mehreren Querdrähten 5, 6, die einander kreuzen und an den Kreuzungspunkten miteinander verschweißt sind. Der gegenseitige Abstand der Längsdrähte 3, 4 und der Querdrähte 5, 6 zueinander wird entsprechend den sta- tischen Anforderungen an das Bauelement gewählt und liegt beispielsweise im Bereich von 50 bis 150 mm, wobei die Abstände im Rahmen der Erfindung gleich groß oder unterschiedlich sein können. Die Durchmesser der Längs- und Querdrähte 3, 4 bzw. 5, 6 sind ebenfalls entsprechend den statischen Erfordernissen an das Bauelement wählbar und liegen vorzugsweise im Bereich von 2 bis 7 mm. Die Oberfläche der Gittermattendrähte 3, 4, 5, 6 kann im Rahmen der Erfindung glatt oder gerippt sein. Die beiden Drahtgittermatten 1, 2 sind miteinander durch mehrere Stegdrähte 7, 7' zu einem formstabilen Gitterkörper verbunden. Die Stegdrähte 7, 7' sind an ihren Enden jeweils mit den Drähten der beiden Drahtgittermatten 1, 2 verschweißt, wobei im Rahmen der Erfindung die Stegdrähte 7, 71 entweder, wie in Fig. 1 dargestellt, mit den jeweiligen Längsdrähten 3, 4 oder mit den Querdrähten 5, 6 verschweißt werden. Die Stegdrähte 7, 7' sind alternierend gegensinnig schräg, d.h. fach- werkartig angeordnet, wodurch der Gitterkörper gegen Scherbe- anspruchung versteift wird.The component shown schematically in Fig. 1 is used to form partitions and partitions of a building. The component consists of two wire mesh mats 1, 2, which are arranged at a predetermined distance parallel to each other. Each wire mesh mat 1 or 2 consists of a plurality of longitudinal wires 3, 4 and a plurality of transverse wires 5, 6, which intersect each other and are welded together at the crossing points. The mutual distance of the longitudinal wires 3, 4 and the transverse wires 5, 6 to each other is selected according to the static requirements of the component and is for example in the range of 50 to 150 mm, wherein the distances in the invention may be the same or different , The diameters of the longitudinal and transverse wires 3, 4 and 5, 6 are also selected according to the static requirements of the component and are preferably in the range of 2 to 7 mm. The surface of the lattice mat wires 3, 4, 5, 6 may be smooth or ribbed in the context of the invention. The two wire mesh mats 1, 2 are connected to one another by a plurality of web wires 7, 7 'to a dimensionally stable grid body.

The web wires 7, 7 'are alternately inclined in opposite directions, that is, arranged like a truss, whereby the grid body is stiffened against shearing stress.
Die Abstände der Stegdrähte 7, 71 zueinander und ihre Verteilung im Bauelement hängen von der statischen Anforderung an das Bauelement ab und betragen beispielsweise entlang der Längsdrähte 200 mm und entlang der Querdrähte 100 mm. Die ge- genseitigen Abstände der Stegdrähte 7, 71 in Richtung der Gittermatten-Längsdrähte 3, 4 und der Gittermatten-Querdrähte 5, 6 betragen zweckmäßig ein Vielfaches der Maschenteilung.The distances between the webs 7, 7 1 to each other and their distribution in the device depend on the static requirement of the device and be, for example, along the longitudinal wires 200 mm and along the transverse wires 100 mm. The mutual distances of the web wires 7, 7 1 in the direction of the grid mesh longitudinal wires 3, 4 and the grid mesh transverse wires 5, 6 are expediently a multiple of the mesh pitch.
Im Zwischenraum zwischen den Drahtgittermatten 1, 2 ist in einem vorgegebenen Abstand von den Drahtgittermatten 1, 2 ein formstabiler Isolierkörper 8 angeordnet, dessen Deckflächen 9, 91 parallel zu den Drahtgittermatten 1, 2 verlaufen. Der Isolierkörper 8 dient zur Wärmeisolierung und Schalldämmung und besteht beispielsweise aus Schaumkunststoffen, wie Polystyrol- oder Polyurethanschaum. Die Dicke des Isolierkör- pers 8 ist frei wählbar und liegt beispielsweise im Bereich von 20 bis 200 mm. Die Abstände des Isolierkörpers 8 zu den Drahtgittermatten 1, 2 sind ebenfalls frei wählbar und liegen beispielsweise im Bereich von 10 bis 30 mm. Der Isolierkörper 8 ist mittig zu den beiden Drahtgittermatten 1, 2 angeordnet, wobei der Abstand zu jeder Drahtgittermatte 1, 2 vorzugsweise 10 bis 50 mm beträgt. Im Rahmen der Erfindung kann der Abstand des Isolierkörpers 8 zu einer Drahtgittermatte 1 bzw. 2 größer als der Abstand des Isolierkörpers 8 zur anderen Drahtgitter- matte 2 bzw. 1 sein. Des weiteren ist es im Rahmen der Erfindung möglich, daß zumindest eine Drahtgittermatte 1, 2 den Isolierkörper 8 an zumindest einer Seitenfläche des Isolierkörpers 8 seitlich überragt. Außerdem ist es im Rahmen der Er- findung möglich, daß der Isolierkörper 8 an zumindest einer Seitenfläche des Isolierkörpers 8 zumindest eine Drahtgittermatte 1; 2 seitlich überragt.In the space between the wire mesh mats 1, 2, a dimensionally stable insulating body 8 is arranged at a predetermined distance from the wire mesh mats 1, 2, the cover surfaces 9, 9 1 parallel to the wire mesh mats 1, 2 extend. The insulating body 8 is used for thermal insulation and sound insulation and consists for example of foamed plastics, such as polystyrene or polyurethane foam. The thickness of the insulating body 8 is freely selectable and is for example in the range of 20 to 200 mm. The distances of the insulating body 8 to the wire mesh mats 1, 2 are also freely selectable and are for example in the range of 10 to 30 mm. The insulating body 8 is arranged centrally to the two wire mesh mats 1, 2, wherein the distance to each wire mesh mat 1, 2 is preferably 10 to 50 mm. In the invention, the distance between the insulating body 8 to a wire mesh mat 1 and 2 greater than the distance of the insulating body 8 to the other wire mesh mat 2 or 1 be. Furthermore, it is possible within the scope of the invention that at least one wire mesh mat 1, 2 projects laterally beyond the insulating body 8 on at least one side surface of the insulating body 8. Moreover, it is possible within the scope of the invention for the insulating body 8 to be provided on at least one side surface of the insulating body 8 with at least one wire mesh mat 1; 2 surmounted laterally.
Das Bauelement ist in beliebiger Länge und Breite herstellbar, wobei sich auf Grund des Herstellungsverfahrens eine Mindestlänge von 100 cm und Standardbreiten von 60 cm, 100 cm, 110 cm und 120 cm als vorteilhaft erwiesen haben.The component can be produced in any desired length and width, with a minimum length of 100 cm and standard widths of 60 cm, 100 cm, 110 cm and 120 cm having proven to be advantageous on the basis of the manufacturing process.
Wie in Fig. 1 schematisch dargestellt ist, werden an beiden Drahtgittermatten 1, 2 je eine Schale 10 bzw. 11 aus Leichtbaumaterial, vorzugsweise aus mit Glasfasern verstärktem Gips, aufgebracht, die an den Isolierkörper 8 anschließt und die jeweilige Drahtgittermatte 1 bzw. 2 umschließt. Die Dicke der Schalen 10, 11 wird entsprechend den baulichen Anforderungen an das Bauelement gewählt und beträgt beispielsweise 20 bis 200 mm. Die beiden Schalen 10 und 11 werden vorzugsweise am Verwendungsort des Bauelementes aufgebracht, beispielsweise im Naßverfahren aufgespritzt, wobei dies vorzugsweise in mehreren Arbeitsgängen geschieht. Im Rahmen der Erfindung ist es jedoch auch möglich, die beiden Schalen 10, 11 oder zumindest eine Schale 10 bzw. 11 in einer entsprechenden Gußform zu gießen, wobei dies im Rahmen der Erfindung bereits im Herstellerwerk oder am Verwendungsort des Bauelementes geschehen kann.As shown schematically in FIG. 1, a shell 10 or 11 of lightweight construction material, preferably of glass-fiber-reinforced plaster, is applied to both wire mesh mats 1, 2, which adjoins the insulating body 8 and encloses the respective wire mesh mat 1 or 2 , The thickness of the shells 10, 11 is selected according to the structural requirements of the device and is for example 20 to 200 mm. The two shells 10 and 11 are preferably applied at the point of use of the component, for example sprayed by wet method, which is preferably done in several operations. In the context of the invention, however, it is also possible to cast the two shells 10, 11 or at least one shell 10 and 11 in a corresponding mold, which can be done within the invention in the factory or at the point of use of the device.
Um die Haftung der Schalen 10, 11 an den Deckflächen 9, 9' des Isolierkörpers 8 zu verbessern, können die Deckflächen 9, 9' des Isolierkörpers 8 im Rahmen der Erfindung aufgerauht sein und/oder Vertiefungen aufweisen. Des weiteren ist es im Rahmen der Erfindung zur Verbesserung der Haftfähigkeit der Schalen 10, 11 an den Deckflächen 9, 9' des Isolierkörpers 8 möglich, an diesen ein Putzträgergitter anzubringen.In order to improve the adhesion of the shells 10, 11 to the cover surfaces 9, 9 'of the insulating body 8, the cover surfaces 9, 9' of the insulating body 8 may be roughened within the scope of the invention and / or have recesses. Furthermore, it is within the scope of the invention to improve the adhesion of the Shells 10, 11 on the top surfaces 9, 9 'of the insulating 8 possible to attach a plaster carrier grid to this.
Der für die Schalen 10, 11 verwendete glasfaserverstärkte Gips muß in seiner Zusammensetzung und in seinem Mischungsver- hältnis an den Verwendungszweck und die Verarbeitungsbedingungen angepaßt sein. Die Grundrezeptur besteht aus handelsüblichem Gipspulver, Wasser, Glasfasern und Additiven, wobei die Glasfasern und die Additive nur in geringen Mengen beigemischt werden. Die Hauptbestandteile Gipspulver und Wasser werden im Verhältnis 2 zu 1 zusammengemischt, wobei dies in Abhängigkeit von den Mengen der beigemischten Glasfasern und Additiven für das Gipspulver einen Gewichtsanteil im Bereich von 60 bis 65 % und für Wasser im Bereich von 30 bis 35 % ergibt. Der Anteil der Glasfasern ist gering und liegt im Bereich von 1 bis 2 Ge- wichtsprozenten. Die Glasfasern werden aus einem Faserbündel („rovings") von endlosen, gestreckten Fasern mit einem Längengewicht, d.h. einer Tex-Zahl („roving density")/ von 2400 g/km hergestellt, wobei das Vormaterial eine spezifische Dichte von 1,2 bis 1,3 g/cm3 hat, und jede Faser einen Durchmesser von 10 bis 15 μm aufweist. Die Glasfasern werden durch geeignete Verfahren von dem Faserbündel abgeschnitten, wobei die Länge der einzelnen vom Faserbündel abgetrennten Glasfasern im Bereich von 10 bis 20 mm liegt. Im Rahmen der Erfindung können alle Arten von Glasfasern Verwendung finden, wobei aus Kostengrün- den vorzugsweise die Standardfasern aus E-Glas verwendet werden.The glass-fiber-reinforced gypsum used for the shells 10, 11 must be adapted in its composition and in its mixing ratio to the intended use and the processing conditions. The basic recipe consists of commercial gypsum powder, water, glass fibers and additives, whereby the glass fibers and the additives are admixed only in small amounts. The main components gypsum powder and water are mixed together in a ratio of 2: 1, depending on the amounts of the admixed glass fibers and additives for the gypsum powder, a weight fraction in the range of 60 to 65% and for water in the range of 30 to 35%. The proportion of glass fibers is low and is in the range of 1 to 2% by weight. The glass fibers are made from a roving of continuous, elongated fibers having a length weight, ie a roving density, of 2400 g / km, the starting material having a specific gravity of from 1.2 to 1.3 g / cm 3 , and each fiber has a diameter of 10 to 15 microns. The glass fibers are cut off from the fiber bundle by suitable methods, the length of the individual glass fibers separated from the fiber bundle being in the range of 10 to 20 mm. In the context of the invention, all types of glass fibers can be used, and for reasons of cost, preferably the standard fibers made of E glass are used.
Die Verwendung von Gips anstelle der bisher üblichen Betonwerkstoffe hat den Vorteil einer enormen Gewichtsersparnis und dadurch einer leichteren Handhabung beim Transport und auf der Baustelle. Des weiteren wird durch Verwendung von Gips die Feuerbeständigkeit des Bauelementes erhöht . Die Verstärkung des Gipses durch Glasfasern verhindert eine Rißbildung in den Schalen. Die beigemischten Additive haben je nach Herstellungsverfahren die Aufgabe, die Dauer der Abbindezeit der Gipsmischung zu steuern und gleichzeitig die bausphysikalischen Werte der Gipsmaterials, insbesondere dessen Druckfestigkeit, zu verbes- sern, wobei die Zusammensetzung, die Menge und das Mischungsverhältnis entsprechend den Anforderungen gewählt wird. Der Anteil der Additive liegt im Bereich von 3,5 bis 5,5 Gewichtsprozenten.The use of gypsum instead of the usual concrete materials has the advantage of an enormous weight saving and thus easier handling during transport and on the construction site. Furthermore, the use of gypsum increases the fire resistance of the component. The reinforcement of the plaster by glass fibers prevents cracking in the shells. The admixed additives, depending on the production process, have the task of controlling the duration of the setting time of the gypsum mixture and at the same time improving the physical properties of the gypsum material, in particular its compressive strength, the composition, the amount and the mixing ratio being selected according to the requirements. The proportion of additives is in the range of 3.5 to 5.5 percent by weight.
Da die im Isolierkörper 8 des Bauelementes liegenden Teilbereiche der Stegdrähte 7, 7' nicht mit glasfaserverstärktem Gips überdeckt werden und daher der Korrosion ausgesetzt sein können, müssen in diesem Fall die Drähte 7, 7' in diesem Bereich mit einer Korrosionsschutzschicht versehen werden. Da die Schalen 10 bzw. 11 aus glasfaserverstärktem Gips bei un- günstigen klimatischen Bedingungen ein gewisse Menge Feuchtigkeit aufnehmen, können auch die Längs- und Querdrähte 3, 4, 5, 6 der entsprechenden Drahtgittermatten 1, 2 einer Korrosion ausgesetzt sein. In diesem Fall ist es erforderlich, auch die Drähte 3, 4, 5, 6 der Drahtgittermatten 1, 2 mit einer Korro- sionsschutzschicht zu versehen. Ein Korrosionsschutz wird vorzugsweise durch Verzinken und/oder Kunststoffbeschichten der Drähte 3, 4, 5, 6, bzw. 7, 7' erreicht. Aus Kostengründen hat es sich als vorteilhaft erwiesen, bereits bei der Herstellung des Gitterkörpers verzinkte Drähte zu verwenden. Die Drähte 3, 4, 5, 6 bzw. 7, 7' können auch aus rostfreien Stahlqualitäten oder aus anderen, nicht korrodierenden Werkstoffen, z.B. Aluminiumlegierungen, hergestellt werden, wobei die Drähte 3, 4, 5, 6 bzw. 7, 7' miteinander verschweißbar sein müssen. Im Rahmen der Erfindung ist es möglich, beim fertigen Bauelement noch vor dem Aufbringen der entsprechenden Schalen aus glasfaserverstärktem Gips die Drahtgittermatten 1, 2 gemeinsam mit den aus dem Isolierkörper 8 herausragenden Bereichen der Stegdrähte 7, 71 mit einer Korrosionsschutzschicht zu versehen. Dies kann beispielsweise durch Eintauchen der entsprechenden Drahtgittertnatten 1, 2 samt angrenzender Bereiche der Stegdrähte 7, 7' in einem Verzinkungsbad geschehen.Since lying in the insulating body 8 of the component portions of the land wires 7, 7 'are not covered with glass fiber reinforced gypsum and therefore may be exposed to corrosion, in this case the wires 7, 7' must be provided in this area with a corrosion protection layer. Since the shells 10 and 11 of glass-fiber-reinforced gypsum absorb a certain amount of moisture under unfavorable climatic conditions, the longitudinal and transverse wires 3, 4, 5, 6 of the corresponding wire mesh mats 1, 2 can also be exposed to corrosion. In this case, it is necessary to provide the wires 3, 4, 5, 6 of the wire mesh mats 1, 2 with a corrosion protection layer. A corrosion protection is preferably achieved by galvanizing and / or plastic coating of the wires 3, 4, 5, 6, or 7, 7 '. For cost reasons, it has proven to be advantageous to use galvanized wires already in the production of the grid body. The wires 3, 4, 5, 6 and 7, 7 'can also be made of stainless steel grades or other, non-corrosive materials, such as aluminum alloys, wherein the wires 3, 4, 5, 6 and 7, 7' must be welded together. In the context of the invention, it is possible to provide the wire mesh mats 1, 2 together with the protruding from the insulating body 8 areas of the land wires 7, 7 1 with a corrosion protection layer before the application of the corresponding shells of glass fiber reinforced plaster. This can be done, for example, by dipping the corresponding Drahtgittertnatten 1, 2 together with adjacent areas of the land wires 7, 7 'in a galvanizing.

Des weiteren ist es im Rahmen der Erfindung möglich, eine der Schalen 10 oder 11 aus Beton herzustellen, so daß die jeweilige Schale 10 bzw. 11 zusammen mit der entsprechenden Drahtgittermatte 1 bzw. 2 einen tragenden Bestandteil des Bauelementes bildet. Furthermore, it is within the scope of the invention possible to produce one of the shells 10 or 11 made of concrete, so that the respective shell 10 or 11 together with the corresponding wire mesh mat 1 and 2 forms a supporting component of the component.
