Description
Die Erfindung geht aus von einem insbesondere aus zementgebundenen Holzfasern gefertigten Schalungselement für die Mantelbetonbauweise mit zwei in Abstand parallel zueinander angeordneten Platten, deren Innenseiten lotrecht verlaufende, paarweise einander gegenüberliegende, zumindest einseitig ausmündende Nuten aufweisen, in die durchbrochene Verbindungsstege eingreifen und mit Hilfe eines Bindemittels befestigt sind.The invention is based on a formwork element made in particular from cement-bound wood fibers for cladding concrete construction with two panels arranged parallel to each other at a distance, their insides perpendicular to each other, in pairs have opposite grooves opening out at least on one side into the perforated Engage connecting webs and are fastened with the help of a binder.
Bei diesem bekannten Schalungselement, das aus Holzfaserplatten gefertigt ist, sind die aus gleichem Baustoff gefertigten Verbindungsstege in den Nuten mit Hilfe eines Klebestoffs befestigt. Diese Befestigungsart hat den Nachteil, daß nur wenige Baustoffe für dieses Schalungselement in Frage kommen. Außerdem ist der Füllbeton lediglich über relativ kleine Öffnungen in den Stegen miteinander verbunden, so daß im Prinzip hier dicht nebeneinander angeordnete Betonsäulen entstehen.In this known formwork element, which is made of wood fiber boards, they are made of the same Connecting webs made of building material are fastened in the grooves with the aid of an adhesive. This type of attachment has the disadvantage that only a few building materials come into question for this formwork element. aside from that if the filling concrete is only connected to one another via relatively small openings in the webs, see above that in principle there are concrete columns arranged close together.
Dieser Nachteil ist bei denjenigen bekannten Scha- «0 lungselementen vermieden, bei denen die Verbindungsstege aus gitterartig verbundenen Drähten, Baustählen od. dgl. bestehen. Diese weisen bei einem bekannten Schalungselement an den quer zu den Platten verlaufenden Drähten über den parallel zur Plattenebene verlaufenden Draht hinaus Spitzen auf, die die Platten durchqueren und auf den Außenseiten der Platten umgebogen sind. Abgesehen davon, daß diese Befestigung ein ungewolltes Parallelverschieben der Platten zuläßt, wobei der Abstand der Platten zueinander sich verändert, stellen die die Platten durchquerenden Teile Kältebrücken dar.This disadvantage is avoided in those known formwork elements in which the connecting webs of wires connected in a grid-like manner, structural steels or the like. These point to one known formwork element on the wires running transversely to the panels over the parallel to the Plate-level wire also has tips that traverse the plates and on the outsides of the plates are bent. Apart from the fact that this attachment causes an unwanted parallel movement allows the plates, the distance between the plates changing to each other, make the Parts crossing panels represent thermal bridges.
Schließlich ist es auch bekannt, die Stege entweder in Form von Bügeln mit Spitzen an den Schenkeln zu bilden, die von oben und/oder unten in diePlattenkanten eingetrieben sind, oder Abstandstäbe mit aufgespaltenen oder sonstwie verbreiterten Enden zu verwenden, die bei der Fertigung der Schalungselemente während der Herstellung der Platten in diese eingeformt werden. Beide Arten lassen ebenfalls nur eine beschränkte Anzahl von Plattenbaustoffen zu. Außerdem ist im ersten Fall die Gefahr des Absprengens von Plattenteilen gegeben, während im zweiten Fall die Fertigung umständlich ist.Finally, it is also known to have the webs either in the form of brackets with points on the thighs that are driven into the panel edges from above and / or below, or spacer bars with split or otherwise widened ends to be used in the manufacture of the formwork elements during the manufacture of the panels in these are molded. Both types also only allow a limited number of panel building materials to. In addition, in the first case there is a risk of parts of the plate bursting off, while in the second case the production is cumbersome.
Es ist ferner schon vorgeschlagen worden, die Stege aus Drähten od. ä. mit Hilfe von Mörtelhäufchen an den Platten zu befestigen. Diese Befestigungsart vermeidet zwar eine Reihe der vorgeschilderten Nachteile, ist jedoch zwangläufig nur in einem beschränkten Umfange belastbar.It has also already been proposed that the webs of wires or the like with the help of piles of mortar to attach to the plates. This type of attachment avoids a number of the above Disadvantages, however, is inevitably only resilient to a limited extent.
Die Erfindung bezweckt, diese Befestigungsart weiter zu verbessern.The aim of the invention is to further improve this type of fastening.
Ausgehend von dem eingangs näher bezeichneten Schalungselement wird dies dadurch erreicht, daß die Verbindungsstege aus gitterartig verbundenen Drähten, Baustählen od. dgl. bestehen, die im Nutbereich je einen parallel zur Nut verlaufenden Draht od. dgl. tragen und außerhalb der Nuten mit einem die Nuten abdeckenden Streifen versehen sind.Starting from the formwork element described in more detail at the outset, this is achieved in that the Connecting webs made of wires, structural steels or the like connected in a grid-like manner, which are located in the groove area Carry a wire or the like running parallel to the groove and outside the grooves with one of the grooves covering strips are provided.
Die Erfindung macht dabei Gebrauch von den bekannten Verbindungsstegen aus gitterartig verbundenen Drähten. Sie erschöpft sich aber nicht allein in der bloßen Verwendung dieser bekannten Verbindungsstege, sondern es sind noch weitere neuartige Mittel vorgesehen, mit denen nicht nur ein außerordentlich steifes Schalungselement gegeben, sondern auch ein sehr einfaches Fertigungsverfahren erzielt worden ist. Die Platten brauchen hierbei lediglich an die Verbindungsstege herangeschoben und die Nuten mit Zementmörtel od. dgl. verfüllt werden. Der dabei die Nut abdeckende Streifen macht nicht nur gesondertes Schalungsmaterial für die Nut entbehrlich, sondern hält auch jeden parallel zur Nut verlaufenden Draht od. dgl. im gewünschten Abstand, so daß er allseitig vom Mörtel umhüllt ist. Die bei der Schilderung des Standes der Technik aufgezeigten Nachteile sind vermieden.The invention makes use of the known connecting webs connected in a grid-like manner Wires. But it is not limited to the mere use of these well-known connecting bridges, but there are also other novel means foreseen, with which not only one extraordinary given rigid formwork element, but also achieved a very simple manufacturing process has been. The plates only need to be pushed up to the connecting webs and the grooves be filled with cement mortar or the like. The strip that covers the groove does more than just do something special Formwork material for the groove is unnecessary, but also holds each one running parallel to the groove Wire or the like at the desired distance so that it is covered on all sides by the mortar. The at the The disadvantages shown by the prior art are avoided.
Zweckmäßig können einzelne der quer zu den Platten verlaufenden Drähte od. dgl. der Verbindungsstege in an sich bekannter Weise über den parallel zur Nut verlaufenden Draht hinaus zu Spitzen verlängert sein, die in den Plattenbaustoff eingreifen, ihn aber nicht durchqueren. Dadurch erübrigen sich bei der Fertigung der Schalungselemente besondere Mittel zum Halten der Platten. Die Teile lassen sich somit auch auf der Baustelle schnell und ohne Aufwand zusammenfügen.Advantageously, individual wires or the like running transversely to the plates can be used in the connecting webs in a manner known per se beyond the wire running parallel to the groove be extended, which intervene in the panel building material, but do not cross it. This eliminates the need special means for holding the panels in the manufacture of the formwork elements. The parts can be thus assemble quickly and easily on the construction site.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.
In die in Abstand parallel zueinander angeordneten Platten 1, 2 aus zementgebundenen Holzfasern greifen die Spitzen 5 des Verbindungsstegs, und zwar innerhalb der Nuten 3, die in den einander zugekehrten Seiten der Platten 1,2 paarweise einander gegenüberliegen. Die Verbindungsstege bestehen aus gitterartig verbundenen Drähten 4,7,8, wobei die Drähte 4,8 waagerecht und die Drähte 7 lotrecht verlaufen. Die Enden der Drähte 4 sind dabei zu den Spitzen 5 verlängert.Reach into the panels 1, 2 made of cement-bonded wood fibers, which are arranged parallel to one another at a distance the tips 5 of the connecting web, within the grooves 3 in the facing Sides of the plates 1,2 face each other in pairs. The connecting webs consist of a grid connected wires 4,7,8, with the wires 4.8 running horizontally and the wires 7 running vertically. The ends of the wires 4 are extended to the tips 5.
Ferner sind Streifen 6 — im Beispiel Blechstreifen — an den Drähten 4,8 vorgesehen, durch die die Nuten 3 abgedeckt sind. Zweckmäßig münden die Nuten 3 an den oberen Plattenkanten aus, wobei die Streifen 3 ebenfalls bis zur Plattenkante geführt sind. Diese Maßnahme erleichtert das Einfüllen des Zementmörtels.Furthermore, strips 6 - in the example sheet metal strips - are provided on the wires 4, 8 through which the Grooves 3 are covered. The grooves 3 expediently open out at the upper plate edges, the Strips 3 are also led to the edge of the plate. This measure makes it easier to fill in the cement mortar.
Da die in den Plattenbaustoff greifenden Spitzen 5 bereits ein geringes Maß an Stabilität gewährleisten, können die Schalungselemente bereits nach dem Vergießen der Nuten 3 zum Zwecke des Abbindens des Mörtels beiseite gestellt werden. Die aus Blech bestehenden Streifen 6 sind mit den Drähten 4,8 beispielsweise durch Schweißen verbunden.Since the tips 5 reaching into the panel building material already ensure a low degree of stability, the formwork elements can be set aside after the grooves 3 have been poured for the purpose of setting the mortar. The strips 6 made of sheet metal are connected to the wires 4, 8, for example by welding.
