Description

Schalungselement für die Mantelbetonbauweise Die Erfindung bezieht sich auf ein aus zwei im Abstand parallel zueinander angeordneten Platten aus einem gebundenen faserigen Baustoff, z. B. zementgebundenen Holzfasern od. dgl. bestehendes Schalungselement für die Mantelbetonbauweise, desden Platten durch im Baustoff verankerte Abstandhalter miteinander verbunden sind.Formwork element for shell concrete construction The invention relates on one of two spaced parallel plates from one bound fibrous building material, e.g. B. cement-bonded wood fibers or the like. Existing Formwork element for shell concrete construction, desden panels anchored in the building material Spacers are connected to each other.

Bei derartigen Schalungselementen hat es sich als nachteilig erwiesen, daß durch die Hohlräume im Baustoff der Platten die verankerten Enden der Abstandhalter keinen festen Sitz haben. Die Abstandhalter wackeln, so daß es beim Versetzen der Schalungselemente Schwierigkeiten bereitet, wenn es nicht praktisch unmöglich ist, völlig ebene Wände zu erhalten. Beim Einfüllen des Betons in die versetzten Schalungselemente besteht auch die Gefahr, daß durch den waagerechten Druck des Füllbetons senkrecht zu den Platten, diese im Bereich der eingebetteten Enden der gegebenenfalls aus Draht gefertigten Abstandhalter ausreißen können.In the case of such formwork elements, it has proven to be disadvantageous that through the cavities in the building material of the panels, the anchored ends of the spacers do not have a secure fit. The spacers wobble so that when the Formwork elements cause difficulties if it is not practically impossible to to get completely flat walls. When pouring the concrete into the staggered formwork elements there is also the risk of being vertical due to the horizontal pressure of the filling concrete to the plates, these in the area of the embedded ends of the possibly made Wire-made spacers can tear out.

Die Erfindung hat sich zum Ziel gesetzt, die geschilderten Nachteile zu vermeiden.The invention has set itself the goal of the disadvantages outlined to avoid.

Diese Aufgabe wird nach der Erfindung bei dem eingangs näher beschriebenen Schalungselement dadurch gelöst, daß der Baustoff der Platten in den Bereichen der in den Platten verankerten Enden der Abstandhalter verfestigt ist.According to the invention, this object is described in more detail in the introduction Formwork element solved in that the building material of the panels in the areas of anchored in the plates ends of the spacer is solidified.

Zum Herstellen der verfestigten Bereiche im Baustoff der Platten des Schalungselements wird zweckmäßig in den Baustoff der Platten ein pulverförmiges, aushärtendes Mittel eingepreßt. Vorteilhaft kann als Verfestigungsmittel Zement verwendet werden, der mittels Druckluft in die Hohlräume des Baustoffs der Platten eingepreßt und unter dem Einfluß der im Baustoff noch vorhandenen Feuchtigkeit erhärtet ist.For producing the consolidated areas in the building material of the panels of the Formwork element is expediently a powdery, curing agent pressed in. Cement can advantageously be used as a solidifying agent are used, which by means of compressed air into the cavities of the building material of the panels pressed in and hardened under the influence of the moisture still present in the building material is.

In der Zeichnung ist das Schalungselement in einem Ausführungsbeispiel dargestellt. Es zeigt F i g. 1 ein Schalungselement in der Draufsicht, und F i g. 2 eine Platte des Schalungselements nach F i g. 1 im Querschnitt im Bereich der Einbettung eines Abstandhalters.In the drawing, the formwork element is in one embodiment shown. It shows F i g. 1 a formwork element in plan view, and FIG. 2 a plate of the formwork element according to FIG. 1 in cross section in the area of Embedding a spacer.

Das Schalungselement besteht aus den beiden Platten 1 und 2, die aus einem durch Zement oder durch ein anderes Bindemittel gebundenen Faserstoff, vorzugsweise Holzfasern, gefertigt sind. Die Platten 1 und 2 sind durch Abstandhalter 3 in gegenseitigem Abstand gehalten. Die Abstandhalter 3 aus zwei parallellaufenden Metallstäben sind innerhalb des Baustoffs der Platten 1 und 2, wie aus F i g. 2 ersichtlich, mit abgewinkelten Enden 4 versehen. Die Schalungselemente selbst werden in der Weise hergestellt, daß die Abstandhalter 3 bereits bei der Herstellung der Platten 1, 2 mit ihren Enden 4 in diesen verankert werden. Im Bereich zwischen den Enden 4 des Abstandhalters 3 und der der jeweils anderen Platte 2 bzw. 1 zugekehrten Seite jeder Platte 1 bzw. 2 soll ihr Baustoff verfestigt werden, da die zementgebundenen Holzfasern an sich nicht besonders geeignet sind, die Abstandhalter 3 darin fest zu verankern. Um dies zu erreichen, sind in den Bereichen 5 die Platten 1 und 2 durch Einpressen von pulverförmigem Zement verdichtet und verfestigt. Der pulverförmige Zement wird zweckmäßig durch aufzusetzende Glocken 6 mit Hilfe von Druckluft in den Baustoff der Platten 1, 2 eingepreßt. Die Glocken 6 sind über Leitungen 7 an einem Zementdruckluftbehälter angeschlossen. Selbstverständlich können die Glocken 6 um ein Glied 8 der Abstandhalter 3 herum auf die Platten 1, 2 aufgesetzt werden, um die Bereiche 5 möglichst zu vergrößern.The formwork element consists of the two panels 1 and 2, which are made of a fibrous material, preferably wood fibers, bound by cement or another binding agent. The plates 1 and 2 are held at a mutual distance from one another by spacers 3. The spacers 3 made of two parallel metal rods are within the building material of the panels 1 and 2, as shown in FIG. 2 can be seen, provided with angled ends 4. The formwork elements themselves are manufactured in such a way that the spacers 3 are anchored in the panels 1, 2 with their ends 4 during the manufacture of the panels. In the area between the ends 4 of the spacer 3 and the side of each plate 1 or 2 facing the other plate 2 or 1, their building material should be solidified, since the cement-bonded wood fibers are not particularly suitable to hold the spacers 3 firmly in them anchor. In order to achieve this, the panels 1 and 2 are compacted and solidified in areas 5 by pressing in powdered cement. The powdery cement is expediently pressed into the building material of the panels 1, 2 through bells 6 to be attached with the aid of compressed air. The bells 6 are connected via lines 7 to a cement compressed air container. Of course, the bells 6 can be placed around a link 8 of the spacers 3 on the plates 1, 2 in order to enlarge the areas 5 as much as possible.

Der Baustoff der Platten 1 und 2, hier zementgebundene Holzfasern, ist genügend porös, um den Zement oder ein anderes pulverförmiges Verdichtungs- und Verfestigungsmittel, z. B. Kunstharz usw., eintreten zu lassen. Der Zement härtet unter dem Einfluß der in der Platte noch vorhandenen Feuchtigkeit aus und verfestigt damit die Bereiche 5 der Platten 1, 2.The building material of the panels 1 and 2, here cement-bonded wood fibers, is sufficiently porous to absorb the cement or another powdery compacting and solidifying agent, e.g. B. synthetic resin, etc., to enter. The cement hardens under the influence of the moisture still present in the plate and thus solidifies the areas 5 of the plates 1, 2.

Die Verfestigung kann auch mit flüssigen Mitteln, z. B. Zementmilch, erfolgen. Auch ein Ausstäuben z. B. mit dem Pinsel oder Einstäuben mit dem Verfestigungsmittel kann erfolgen. Das Verfestigungsmittel kann auch ein wärmeerhärtendes oder ähnliches Kunstharz oder eine Kunstharzlösung sein.The solidification can also be done with liquid agents, e.g. B. cement milk, take place. Dusting z. B. with a brush or dusting with the solidifying agent may happen. The solidifying agent can also be thermosetting or the like Resin or a resin solution.
