Abstract

The shuttering mould has a comparatively rigid slab and a plurality of load-bearing feet (5) attached on one side of the slab (6). The load-bearing slab (6) consists preferably of pressed cellulose and the load-bearing feet (5) are produced preferably from polypropylene. On the underside of the load-bearing feet (5) there is arranged in each case a flexible neck collar (9) having an opening (8) through which, in the case of a load-bearing foot (5') not bearing at the bottom on an underfloor (1), floor material (4) applied at the top of the mould (3) can escape at the bottom. The neck collar (9) forms a seal with respect the underfloor (1) and prevents the escaped floor material (4) from escaping laterally. As a result, it is ensured that all the load-bearing feet (5, 5') rest on the bottom, even in the case of an uneven underfloor (1). However, it is possible to walk on the shuttering mould during mounting. <IMAGE>

Description

Die Erfindung betrifft eine Schalungsmatrize für einen Hohlraumboden, mit einer im wesentlichen ebenen und starren Platte sowie mehreren auf der einen Seite der Platte angebrachten becherförmigen Tragfüssen mit jeweils einem offenen Boden, die von der anderen Seite der Platte her über entsprechende Löcher der Platte mit einem fliessfähigen Bodenmaterial füllbar sind.The invention relates to a formwork matrix for a cavity floor, with a substantially flat and rigid plate and a plurality of cup-shaped support feet, each with an open base, attached to one side of the plate and flowing from the other side of the plate via corresponding holes in the plate Soil material can be filled.

Eine bekannte Schalungsmatrize dieser Gattung wird vom Anmelder aus Recycling-Zellulose durch Verpressen hergestellt. Die vergleichsweise steife Schalungsmatrize ist beim Montieren begehbar und damit einfach zu verlegen. Da die Unterlagsböden, auf welche die Schalungsmatrizen gelegt werden in der Regel nicht exakt eben sind, hat diese hohe Steifigkeit jedoch den Nachteil, dass vielfach einzelne Tragfüsse der Schalungsmatrize auch bei eingefülltem Bodenmaterial, beispielsweise Sand-Zementmörtel, den Unterlagsboden nicht berühren. Aus Gründen der Stabilität wäre es nun wünschbar, dass sämtliche Füsse auf dem Unterboden aufstehen. Zudem können eventuell einzuziehende Kabel und Leitungen sich unter abstehenden Tragfüssen verklemmen.A known formwork matrix of this type is manufactured by the applicant from recycled cellulose by pressing. The comparatively stiff formwork matrix can be walked on during assembly and is therefore easy to install. Since the sub-floors on which the formwork matrices are usually not exactly level, this high stiffness has the disadvantage that individual support feet of the formwork matrix do not touch the sub-floor, even when the floor material is filled in, e.g. sand-cement mortar. For reasons of stability, it would now be desirable for all feet to stand on the sub-floor. In addition, any cables and lines that may have to be pulled in can jam under protruding support feet.

Weiter ist aus der EP-A-0 057 372 eine Schalungsmatrize aus einer vergleichsweise dünnen Kunststofffolie aus biegsamem und geschmeidigem Material bekannt. Diese Folie passt sich beim Aufbringen des fliessfähigen Bodenmaterials an die Unebenheiten des Unterbodens an. Bei der Montage ist diese Schalungsmatrize jedoch nicht begehbar, was die Montage wesentlich erschwert.Furthermore, from EP-A-0 057 372 a formwork matrix made of a comparatively thin plastic film made of flexible and supple material is known. This film adapts to the unevenness of the sub-floor when the flowable floor material is applied. However, this formwork matrix cannot be walked on during assembly, which makes assembly considerably more difficult.

Weiter ist aus der US-A-3,442,058 eine Schalungsmatrize bekannt, die unten offene Füsse aufweist. Bei einem unebenen Unterboden tritt bei nicht aufliegenden Füssen beim Auftragen des fliessfähigen Bodenmaterials dieses teilweise unten aus, was insbesondere dann nicht erwünscht ist, wenn der Hohlraumboden zur Aufnahme von Kabeln und Leitungen vorgesehen ist.Furthermore, from US-A-3,442,058 a formwork matrix is known which has feet open at the bottom. In the case of an uneven subfloor, when the flowable floor material is not in contact with the feet, it partially exits at the bottom, which is particularly undesirable if the cavity floor is provided for receiving cables and lines.

Der Erfindung liegt die Aufgabe zugrunde, eine Schalungsmatrize der genannten Gattung zu schaffen, welche die oben genannten Nachteile vermeidet. Die Schalungsmatrize soll somit auch bei einem unebenen Unterboden an allen Füssen abgestützt sein. Trotzdem soll die Schalungsmatrize sehr kostengünstig herstellbar und beim Montieren begehbar sein. Die Aufgabe ist durch die Erfindung gemäss Anspruch 1 gelöst.The invention has for its object to provide a formwork matrix of the type mentioned, which avoids the disadvantages mentioned above. The formwork matrix should therefore be supported on all feet even on an uneven sub-floor. Nevertheless, the formwork matrix should be very inexpensive to manufacture and accessible when assembling. The object is achieved by the invention according to claim 1.

Bei der erfindungsgemässen Schalungsmatrize weisen die Tragfüsse jeweils an ihrem Boden eine flexible Halskrause mit einer durch austretendes Bodenmaterial aufweitbaren Oeffnung auf. Bei einem auf dem Unterboden nicht aufstehenden Fuss kann deshalb das aufgetragene und fliessfähige Bodenmaterial unten durch die aufweitbare Oeffnung austreten. Dieser schiesslich am Unterboden abgestützte Tragfuss trägt damit ebenfalls den gebildeten Unterlagsboden.In the formwork matrix according to the invention, the support feet each have a flexible neck brace on their base with an opening that can be expanded by emerging floor material. If a foot does not stand up on the sub-floor, the applied and flowable floor material can therefore escape through the expandable opening at the bottom. This support foot, which is finally supported on the sub-floor, thus also carries the sub-floor formed.

Eine besonders einfache Herstellung der erfindungsgemässen Schalungsmatrize ist dann gewährleistet, wenn die Halskrause durch flexible und radial verlaufende Dichtungszungen gebildet ist. Sind nach einer Weiterbildung der Erfindung die Dichtungszungen an einem umlaufenden Rand des Bodens angeformt, so können zumindest die Füsse einstückig hergestellt werden.A particularly simple manufacture of the formwork matrix according to the invention is ensured if the neck brace is formed by flexible and radially extending sealing tongues. If, according to a development of the invention, the sealing tongues are formed on a circumferential edge of the base, at least the feet can be made in one piece.

Nach einer Weiterbildung der Erfindung weisen die Dichtungszungen seitlich nach oben gerichtete flexible Ränder auf. Die Dichtungszungen sind damit etwa schaufelförmig ausgebildet. Damit kann ein seitliches Austreten von Bodenmaterial besonders wirkungsvoll verhindert werden.According to a development of the invention, the sealing tongues have flexible edges directed upwards at the sides. The sealing tongues are thus approximately blade-shaped. Lateral leakage of soil material can thus be prevented particularly effectively.

Nach einer Weiterbildung der Erfindung ist die Platte aus gepresster Zellulose und die Füsse aus Kunststoff hergestellt. Dies erlaubt eine umweltfreundliche Wiederverwertung von Papier- und Kunststoffabfällen. Als Kunststoff eignet sich hier insbesondere Polypropylen.According to a development of the invention, the plate is made of pressed cellulose and the feet are made of plastic. This allows environmentally friendly recycling of paper and plastic waste. Polypropylene is particularly suitable as plastic here.

Eine besonders steife Platte ergibt sich nach einer Weiterbildung der Erfindung dann, wenn diese aus zwei miteinander verbundenen Schichten besteht. Vorzugsweise sind die Schichten miteinander verleimt. Weisen die Füsse oben einen Aussenflansch auf, so können diese in an sich einfacher Weise zwischen den Schichten fixiert werden.According to a development of the invention, a particularly rigid plate is obtained if it consists of two interconnected layers. The layers are preferably glued to one another. If the feet have an outer flange at the top, they can be easily fixed between the layers.

Die Fig. 1 zeigt einen Unterboden 1, beispielsweise ein Rohbetonboden und eine erfindungsgemässe Schalungsmatrize 3 die mit aufgebrachten Beton 4 oder dergleichen einen Unterlagsboden 14 bildet. Zwischen dem Unterboden 1 und dem Unterlagsboden 14 sind Kanäle 2 angeordnet, die zur Aufnahme von Kabeln und Leitungen dienen können. Die Kanäle 2 können jedoch auch Lüftungskanäle sein oder zum Durchleiten von Heissluft zum Heizen dienen. Die Schalungsmatrize 3 bildet somit eine verlorene Blindschalung, die gemäss Fig. 7 vorzugsweise rechteckig mit einer Kantenlänge von etwa 1 m ausgebildet ist. In der Regel werden mehrere ineinander eingehängte Schalungsmatrizen 3 auf den Unterboden 1 gelegt und mit einem fliessfähigen Bodenmaterial 4 belegt.1 shows a sub-floor 1, for example a raw concrete floor and a formwork matrix 3 according to the invention which forms a sub-floor 14 with applied concrete 4 or the like. Channels 2 are arranged between the sub-floor 1 and the sub-floor 14, which can serve to accommodate cables and lines. However, the ducts 2 can also be ventilation ducts or serve to pass hot air through for heating. The formwork matrix 3 thus forms a lost blind formwork, which according to FIG. 7 is preferably rectangular with an edge length of approximately 1 m. As a rule, several formwork matrices 3 suspended in one another are placed on the sub-floor 1 and covered with a flowable floor material 4.

Die Schalungsmatrize 3 besteht aus einer im wesentlichen ebenen Platte 6 mit vorzugsweise kreisrunden Löchern 12, in welche jeweils ein becherförmiger Tragfuss 5 eingesetzt ist. Die Platte 6 kann gemäss Fig. 7 Verstärkungsrillen 13 aufweisen und besteht aus zwei miteinander verleimten Schichten 6a und 6b. Diese Schichten 6a und 6b sind vorzugsweise aus gepresster Zellulose hergestellt. Die vorzugsweise kreisrunden Tragfüsse 5 weisen am oberen Rand einen angeformten Aussenflansch 11 auf, der zwischen die Schichten 6a und 6b der Platte 6 eingreift und der mit diesen Schichten verleimt oder durch Heissfügen verbunden ist.The formwork matrix 3 consists of an essentially flat plate 6 with preferably circular holes 12, in each of which a cup-shaped support foot 5 is inserted. 7, the plate 6 can have reinforcing grooves 13 and consists of two layers 6a and 6b glued together. These layers 6a and 6b are preferably made of pressed cellulose. The preferably circular support feet 5 have an integrally formed outer flange 11 on the upper edge, which between the Layers 6a and 6b of the plate 6 engage and which is glued to these layers or connected by hot joining.

Die Füsse 5, sind vorzugsweise einstückig aus Kunststoff, vorzugsweise Polypropylen hergestellt. Denkbar ist jedoch auch eine Ausführung, bei welcher die Füsse 5 ebenfalls aus verpresster Zellulose hergestellt sind. Die Füsse 5 weisen unten eine Halskrause 9 mit einer mittig angeordneten Oeffnung 8 auf. Diese Halskrause 9 besteht aus mehreren Dichtungszungen 9a, die an einem umlaufenden Rand 7a angeformt sind und die sich radial nach innen erstrecken. Diese vorzugsweise dünnwandigen, beispielsweise 0,5 mm starken Dichtungszungen sind flexibler als die übrigen Bereiche der Schalungsmatrize 3 und weisen seitlich nach oben gerichtete Ränder 9b auf. Radial verlaufende Stege 10 verschliessen die Oeffnung 8 bereichsweise und stabilisieren den Fuss 5.The feet 5 are preferably made in one piece from plastic, preferably polypropylene. However, an embodiment is also conceivable in which the feet 5 are also made of pressed cellulose. The feet 5 have at the bottom a ruff 9 with a centrally arranged opening 8. This ruff 9 consists of several sealing tongues 9a, which are formed on a peripheral edge 7a and which extend radially inwards. These preferably thin-walled, for example 0.5 mm thick sealing tongues are more flexible than the other areas of the formwork matrix 3 and have laterally upwardly directed edges 9b. Radially extending webs 10 partially close the opening 8 and stabilize the foot 5.

Die Fig. 1 zeigt links einen Fuss 5, der auf dem Unterboden 1 aufsteht und rechts daneben einen Fuss 5', bei welchem die Unterseite der Schalungsmatrize 3 zum Unterboden 1 einen Abstand A von beispielsweise 10 mm aufweist. Beim links gezeigten Fuss 5 ist das Bodenmaterial 4 unten nicht ausgetreten, da die Oeffnung 8 durch den anliegenden Unterboden 1 verschlossen ist. Beim Fuss 5' ist hingegen durch die Oeffnung 8 Bodenmaterial 4 nach unten ausgetreten. Dieses ausgetretene Material bildet einen Sockel 15, welcher den Zwischenraum A ausfüllt und den Unterboden 1 mit dem Fuss 5' verbindet. Wie insbesondere Fig. 3 zeigt, ist die Oeffnung 8 aufgeweitet und die Halskrause 9 bildet eine Ummantelung des Sockels 15.1 shows on the left a foot 5 which stands on the sub-floor 1 and on the right next to it a foot 5 'in which the underside of the formwork matrix 3 is at a distance A of, for example, 10 mm from the sub-floor 1. In the case of the foot 5 shown on the left, the bottom material 4 has not emerged at the bottom, since the opening 8 is closed by the underlying underbody 1. At foot 5 ', however, is emerged through the opening 8 bottom material 4 down. This leaked material forms a base 15 which fills the space A and connects the underbody 1 to the foot 5 '. As shown in FIG. 3 in particular, the opening 8 is widened and the ruff 9 forms a covering of the base 15.

Die Dichtungszungen 9a der Halskrause 9 werden somit bei einem abstehenden Fuss 5' beim Auftragen des Bodenmaterials 4 unter Aufweitung der Oeffnung 8 elastisch nach unten ausgelenkt und bilden eine Dichtung, welche das seitliche Austreten des Bodenmaterials 4 verhindert. Da das Bodenmaterial 4 vergleichsweise grob und zähflüssig ist, kann dieses durch ebenfalls aufgeweitete Zwischenräume 16 nicht austreten, zumal diese durch die ebenfalls flexiblen Ränder 9b wenigstens teilweise verschlossen sind.The sealing tongues 9a of the cervical collar 9 are thus deflected elastically downward with a protruding foot 5 'when the base material 4 is applied while widening the opening 8 and form a seal which prevents the base material 4 from escaping laterally. Since the base material 4 is comparatively coarse and viscous, it cannot escape through gaps 16 which are likewise widened, especially since these are at least partially closed by the likewise flexible edges 9b.
