Definitions
- the invention relates to a formwork for foundation parts of the type explained in the preamble of claim 1.
- Such formwork is known from DE-OS 34 36 690.
- the known formwork consists of a U-shaped strip from a latticework shrunk with plastic film and forms a channel with vertical side walls into which the concrete is poured from above.
- the cross-section of the finished foundation is thus constant over the entire height of the foundation part, the width of the cross-section over the entire height of the foundation part corresponding to the width of the standing area necessary for the corresponding floor conditions.
- the supports or the wall receiving surface of the foundation part must theoretically only be so large that supports or wall can lie snugly.
- the invention is based on the object of providing a formwork which avoids an additional consumption of concrete at low labor costs.
- the design according to the invention creates a formwork that is just as easy and inexpensive to handle as the formwork of the prior art, but requires significantly less concrete. Due to the flexibility of the latticework shrink-wrapped with plastic film, cross-sectional shapes can also be produced which cannot be manufactured with conventional formwork means, for example boards, or only with an unacceptably high amount of work. Examples of this would be inconsistently tapering or irregular cross sections.
- Claims 2 and 3 describe the application of the invention to a lost (claim 2) or removable and reusable (claim 3) formwork.
- a lost formwork 1 for production of a strip foundation can be seen, which is designed as a channel with two lateral formwork walls 2 and 3 forming the long boundaries of the channel and a formwork floor 4.
- the side formwork walls 2, 3 and the formwork floor 4 are integrally bent from a strip of composite material, which consists of a latticework 5 and a plastic film 6 shrunk onto the latticework 5 on both sides.
- the latticework 5 is preferably one of the usual structural steel mats of suitable strength with crossed transverse or longitudinal bars 5a, 5b.
- the plastic film 6 is one of the usual shrink films of suitable strength, such as can also be used for packaging purposes, for example.
- the plastic film 6 was placed in two webs, 6a, 6b on both sides of the still flat latticework 5 and shrunk under the action of heat, so that it closes tightly around the rods 5a and 5b due to the associated contraction and both layers 6a, 6b through the Openings of the latticework 5 are interconnected. Then the latticework 5 with the shrunk-on plastic film 6 is bent to the desired profile.
- the formwork was designed in such a way that the completely cast foundation part is provided in the lower region 7a in the form of a plate with an elongated rectangular cross section and in the upper region 7b above it with a trapezoidal cross section tapering upwards.
- the floor width b 1 is determined according to static aspects depending on the formwork length l, while the reduced upper width b 2 is coordinated with the necessary footprint for the supports or walls.
- stiffening elements 8 and 9 are arranged in the vicinity of the upper edges of the side formwork walls 2 and 3, which consist of three straight longitudinal rods 8a and 9a and triangular longitudinal rods assembled in a triangle 8b, 9b exist, the curved longitudinal bars 8b, 9b each connecting two of the straight longitudinal bars 8a and 9a. Only two curved longitudinal bars 8b and 9b can be provided per stiffening element 8 and 9, respectively.
- the stiffening elements 8 and 9 are preferably attached to the side walls 2 and 3 with the aid of a spacer 10.
- the spacers 10 penetrate the plastic film 6 and encompass both a transverse or longitudinal rod 5a or 5b of the lattice work and one of the longitudinal rods 8a or 9a of the stiffening elements 8 or 9 using suitable, known connecting means, in the simplest case, wire wire.
- These spacers 10 ensure that both the width b2 of the upper opening of the formwork 1 and the distance between the formwork walls 2 and 3 remain essentially unchanged over the entire height of the formwork walls.
- the narrow sides of the formwork 1 can be closed with suitable pieces of material. Suitable for this are both conventional formwork boards and a correspondingly cut and fastened piece of the material also used for the formwork 1, made of latticework shrunk with plastic film.
- FIG. 3 shows a section similar to FIG. 2 through a further exemplary embodiment of the invention in the form of a reusable formwork 11.
- the formwork 11 consists of at least two opposing formwork walls 12 and 13, each of which is made from a cut strip of the formwork already used for the formwork 1 used, shrunk with plastic film 6 latticework 5 exist. Thereafter, the two side formwork walls 12 and 13 were bent step-like and fixed in mirror image and by means of the spacers 10 already described and in a predetermined distance in parallel to each other and placed on a concreting base 14.
- the greatest width b1 of the formwork 11, the width of the floor area, is in turn based on the static conditions, while the width b2 on the top of the formwork 11 is adapted to the required footprint for supports or walls.
- the cross section of the foundation part produced with the formwork 11 thus has a plate-shaped lower region 15a with an elongated rectangular cross section, a central region 15b with a trapezoidally tapering cross section upwards and an upper region 15c, which in turn is plate-shaped but with a shorter rectangular cross section is.
- stiffening elements 8 and 9 can also be provided here, which have been omitted from the drawing for reasons of clarity.
- the formwork 11, like the formwork 1, can also be closed on its narrow sides.
- the fastenings of the spacers 10 with the formwork walls 12 or 13 are loosened (when using wire, this is pinched off), so that the formwork walls 12 and 13 and possibly also the formwork walls not shown, covering the narrow sides can be removed after the concrete has hardened.
- the formwork can easily be can also be designed as formwork for individual foundations. Due to the flexibility of the latticework, the cross-sectional shapes of the achievable foundation parts are essentially freely selectable, so that they can be adapted to the structural conditions and the calculations without a noticeably increased amount of work, as would be the case with conventional formwork. If necessary, a latticework that is only shrunk on one side with plastic film can be used if the expected corrosive loads allow it. All known types can be used as spacers or stiffening elements.
Abstract
Description
Die Erfindung betrifft eine Schalung für Fundamentteile der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a formwork for foundation parts of the type explained in the preamble of
Eine derartige Schalung ist aus der DE-OS 34 36 690 bekannt. Die bekannte Schalung besteht aus einem U-förmig gebogenen Streifen aus einem mit Kunststoffolie beschrumpften Gitterwerk und bildet eine Rinne mit senkrechten Seitenwänden, in die der Beton von oben her eingegossen wird. Der Querschnitt des fertigen Fundamentes ist somit über die gesamte Höhe des Fundamentteiles konstant, wobei die Breite des Querschnittes über die gesamte Höhe des Fundamentteiles der für die entsprechenden Bodenverhältnisse notwendigen Breite der Standfläche entspricht. Für die Wirksamkeit der Fundamentteile ist es jedoch nur notwendig, eine entsprechend große Standfläche zu haben, die die aufzunehmenden Lasten gleichmäßig im Boden verteilt. Demgegenüber muß die die Stützen oder die Wand aufnehmende Oberfläche des Fundamentteiles theoretisch nur so groß sein, daß Stützen oder Wand satt aufliegen können. Bei der Verwendung der vorbekannten Schalung wird somit wesentlich mehr Beton verbraucht als dies notwendig wäre.Such formwork is known from DE-OS 34 36 690. The known formwork consists of a U-shaped strip from a latticework shrunk with plastic film and forms a channel with vertical side walls into which the concrete is poured from above. The cross-section of the finished foundation is thus constant over the entire height of the foundation part, the width of the cross-section over the entire height of the foundation part corresponding to the width of the standing area necessary for the corresponding floor conditions. For the effectiveness of the foundation parts, however, it is only necessary to have a correspondingly large footprint that distributes the loads to be evenly distributed in the floor. In contrast, the supports or the wall receiving surface of the foundation part must theoretically only be so large that supports or wall can lie snugly. When using the previously known formwork, much more concrete is used than would be necessary.
Die theoretisch mögliche Herstellung von betonsparenden Fundamentteilen mit sich nach oben verjüngendem Querschnitt scheiterte in der Praxis bislang an den hohen Arbeitskosten zum Herstellen der dafür erforderlichen Schalung aus Schalungsbrettern, die die Mehrkosten für die größere Betonmenge übersteigen.The theoretically possible production of concrete-saving foundation parts with an upward tapering cross section has so far failed in practice due to the high labor costs for producing the formwork required for this from formwork boards, which exceed the additional costs for the larger amount of concrete.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Schalung bereitzustellen, die bei geringen Arbeitskosten einen Mehrverbrauch an Beton vermeidet.In contrast, the invention is based on the object of providing a formwork which avoids an additional consumption of concrete at low labor costs.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of
Durch die erfindungsgemäße Ausgestaltung wird eine Schalung geschaffen, die ebenso leicht und kostengünstig handhabbar ist wie die Schalung des Standes der Technik, jedoch wesentlich weniger Beton erfordert. Durch die Biegbarkeit des mit Kunststoffolie beschrumpften Gitterwerkes können auch Querschnittsformen hergestellt werden, die sich mit herkömmlichen Schalungsmitteln, beispielsweise Brettern, nicht oder nur unter einem unvertretbar hohen Arbeitsaufwand fertigen lassen. Beispiele dafür wären sich unstetig verjüngende oder unregelmäßige Querschnitte.The design according to the invention creates a formwork that is just as easy and inexpensive to handle as the formwork of the prior art, but requires significantly less concrete. Due to the flexibility of the latticework shrink-wrapped with plastic film, cross-sectional shapes can also be produced which cannot be manufactured with conventional formwork means, for example boards, or only with an unacceptably high amount of work. Examples of this would be inconsistently tapering or irregular cross sections.
Die Ansprüche 2 und 3 beschreiben die Anwendung der Erfindung auf eine verlorene (Anspruch 2) bzw. entfernbare und wiederverwertbare (Anspruch 3) Schalung.
Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:
- Fig. 1 eine perspektivische, schematische Darstellung eines ersten Ausführungsbeispieles der Erfindung,
- Fig. 2 den Schnitt II-II aus Fig. 1, und
- Fig. 3 einen Schnitt ähnlich Fig. 2 durch ein weiteres Ausführungsbeispiel der Erfindung.
- 1 is a perspective, schematic representation of a first embodiment of the invention,
- Fig. 2 shows the section II-II of Fig. 1, and
- Fig. 3 shows a section similar to FIG. 2 through another embodiment of the invention.
Aus Fig. 1 ist eine verlorene Schalung 1 zur Herstellung eines Streifenfundamentes ersichtlich, die als Rinne mit zwei die langen Begrenzungen der Rinne bildenden seitlichen Schalungswänden 2 und 3 und einem Schalungsboden 4 ausgebildet ist. Die seitlichen Schalungswände 2, 3 und der Schalungsboden 4 sind einstückig aus einem Streifen Verbundmaterial gebogen, das aus einem Gitterwerk 5 und einer beidseitig auf das Gitterwerk 5 aufgeschrumpften Kunststoffolie 6 besteht. Das Gitterwerk 5 ist bevorzugt eine der üblichen Baustahlmatten geeigneter Festigkeit mit gekreuzten Quer- bzw. Längsstäben 5a, 5b. Die Kunststoffolie 6 ist eine der üblichen Schrumpffolien geeigneter Festigkeit, wie sie beispielsweise auch für Verpackungszwecke eingesetzt werden können. Die Kunststoffolie 6 wurde in zwei Bahnen, 6a, 6b beidseitig auf das noch flache Gitterwerk 5 aufgelegt und unter Hitzeeinwirkung geschrumpft, so daß sie sich durch die damit verbundene Kontraktion eng um die Stäbe 5a bzw. 5b legt und beide Lagen 6a, 6b durch die Öffnungen des Gitterwerkes 5 hindurch miteinander verbunden werden. Danach wird das Gitterwerk 5 mit der aufgeschrumpften Kunststoffolie 6 zu dem gewünschten Profil gebogen.From Fig. 1 is a lost
Im Ausführungsbeispiel nach den Fig. 1 und 2 wurde die Schalung derart gestaltet, daß das fertig vergossene Fundamentteil im unteren Bereich 7a plattenförmig mit einem langrechteckigen Querschnitt und im darüberliegenden oberen Bereich 7b mit einem sich nach oben verjüngenden, trapezförmigen Querschnitt versehen ist. Die Bodenbreite b₁ wird nach statischen Gesichtspunkten in Abhängigkeit auch von der Schalungslänge l festgelegt, während die verringerte obere Breite b₂ auf die notwendige Standfläche für die Stützen oder Wände abgestimmt ist.In the exemplary embodiment according to FIGS. 1 and 2, the formwork was designed in such a way that the completely cast foundation part is provided in the
Um den Widerstand der Schalung 1 gegen den Betondruck beim Vergießen zu erhöhen, sind in der Nähe der oberen Ränder der seitlichen Schalungswände 2 bzw. 3 Versteifungselemente 8 bzw. 9 angeordnet, die aus drei im Dreieck zusammengestellten geraden Längsstäben 8a bzw. 9a und gebogenen Längsstäben 8b, 9b bestehen, wobei die gebogenen Längsstäbe 8b, 9b jeweils zwei der geraden Längsstäbe 8a bzw. 9a miteinander verbinden. Dabei können jeweils nur zwei gebogene Längsstäbe 8b bzw. 9b pro Versteifungselement 8 bzw. 9 vorgesehen sein. Die Versteifungselemente 8 bzw. 9 sind bevorzugt mit Hilfe eines Abstandshalters 10 an den Seitenwänden 2 bzw. 3 befestigt. Dabei durchstoßen die Abstandshalter 10 die Kunststoffolie 6 und umgreifen mit geeigneten, bekannten Verbindungsmitteln, im einfachsten Fall Rödeldraht, sowohl einen Quer- bzw. Längsstab 5a bzw. 5b des Gitterwerks als auch einen der Längsstäbe 8a bzw. 9a der Versteifungselemente 8 bzw. 9. Diese Abstandshalter 10 sorgen dafür, daß sowohl die Breite b₂ der oberen Öffnung der Schalung 1 als auch der Abstand zwischen den Schalungswänden 2 bzw. 3 über die gesamte Höhe der Schalungswände im wesentlichen unverändert bleibt. Falls gewünscht, können die Schmalseiten der Schalung 1 mit geeigneten Materialstücken verschlossen werden. Dazu eignen sich sowohl übliche Schalungsbretter als auch ein entsprechend zugeschnittenes und befestigtes Stück des auch für die Schalung 1 verwendeten Materials aus mit Kunststoffolie beschrumpftem Gitterwerk.In order to increase the resistance of the
Fig. 3 zeigt einen Schnitt ähnlich Fig. 2 durch ein weiteres Ausführungsbeispiel der Erfindung in Form einer wiederverwendbaren Schalung 11. Die Schalung 11 besteht aus mindestens zwei sich gegenüberliegenden Schalungswänden 12 bzw. 13, die aus je einem zugeschnittenen Streifen des bereits für die Schalung 1 verwendeten, mit Kunststoffolie 6 beschrumpften Gitterwerks 5 bestehen. Danach wurden die beiden seitlichen Schalungswände 12 bzw. 13 stufenförmig gebogen und mittels der bereits beschriebenen Abstandshalter 10 spiegelbildlich und im vorbestimmten Abstand in Parallellage zueinander fixiert und auf eine Betonierunterlage 14 aufgestellt. Die größte Breite b₁ der Schalung 11, die Breite der Bodenfläche, wird wiederum auf die statischen Gegebenheiten abgestellt, während die Breite b₂ an der Oberseite der Schalung 11 der erforderlichen Standfläche für Stützen bzw. Wände angepaßt ist. Der Querschnitt des mit der Schalung 11 hergestellten Fundamentteiles weist somit einen plattenförmigen unteren Bereich 15a mit einem langrechteckigen Querschnitt, einen mittleren Bereich 15b mit einem sich trapezförmig nach oben verjüngenden Querschnitt und einen oberen Bereich 15c auf, der wiederum plattenförmig aber mit einem kürzeren rechteckigen Querschnitt ausgebildet ist. Selbstverständlich können auch hier wiederum Versteifungselemente 8 bzw. 9 vorgesehen werden, die jedoch aus Gründen der Übersichtlichkeit in der Zeichnung weggelassen wurden. Auch die Schalung 11 kann wie die Schalung 1 an ihren Schmalseiten verschlossen werden. Soll die Schalung entfernt werden, so werden die Befestigungen der Abstandshalter 10 mit den Schalungswänden 12 bzw. 13 gelöst (bei Verwendung von Rödeldraht wird dieser abgezwickt), so daß die Schalungswände 12 bzw. 13 und gegebenenfalls auch die die Schmalseiten bedeckenden, nicht gezeichneten Schalungswände nach dem Aushärten des Betons entfernt werden können.3 shows a section similar to FIG. 2 through a further exemplary embodiment of the invention in the form of a
In Abwandlung der beschriebenen und gezeichneten Ausführungsbeispiele können die Schalungen ohne weiteres auch als Schalungen für Einzelfundamente ausgebildet werden. Durch die Biegbarkeit des Gitterwerkes sind darüber hinaus die Querschnittsformen der erzielbaren Fundamentteile im wesentlichen frei wählbar, so daß sie jeweils an die baulichen Gegebenheiten und die Berechnungen angepaßt werden können, ohne daß ein merklich erhöhter Arbeitsaufwand anfällt, wie dies bei herkömmlichen Schalungen der Fall wäre. Notfalls kann auch ein nur einseitig mit Kunststoffolie beschrumpftes Gitterwerk verwendet werden, wenn es die zu erwartenden korrosiven Belastungen zulassen. Als Abstandshalter bzw. Versteifungselemente können alle bekannte Typen eingesetzt werden.In a modification of the described and drawn exemplary embodiments, the formwork can easily be can also be designed as formwork for individual foundations. Due to the flexibility of the latticework, the cross-sectional shapes of the achievable foundation parts are essentially freely selectable, so that they can be adapted to the structural conditions and the calculations without a noticeably increased amount of work, as would be the case with conventional formwork. If necessary, a latticework that is only shrunk on one side with plastic film can be used if the expected corrosive loads allow it. All known types can be used as spacers or stiffening elements.
