Schalungen für Stützen oder Säulen sind im Stand der Technik seit langem bekannt und gebräuchlich. Sie werden dazu verwendet, bei der Erstellung eines Bauwerks tragende, vertikal orientierte Stützen oder Säulen zu errichten. Dazu werden flächige Schalelemente, z. B. aus Holz oder Metall, dem gewünschten Querschnitt entsprechend zusammengefügt und mit geeigneten Spannvorrichtungen, beispielsweise Schraubzwingen, relativ zueinander festgelegt. Da der hydrostatische Druck des flüssigen Betons im Inneren der Säulenschalung sehr hoch ist, er kann bis zu 60 kN pro qm betragen, ist es notwendig, daß die Spannvorrichtungen entsprechend ausgelegt sind, sowie die Schalelemente über eine ausreichende Stabilität verfügen. Die Erstellung dieser Schalungen auf der Baustelle ist sehr zeitaufwendig und kostenintensiv. Daneben sind seit einiger Zeit Schalrohre aus imprägnierter Pappe bekannt, die zur Erstellung einer Säule mit rechteckigem oder quadratischem Querschnitt innenseitig mit Polystyrol entsprechenden Querschnitts ausgeschäumt sind. Diese Schalungen, die im wesentlichen aus einem Papprohr bestehen, bauchen sich aber in ihrem unteren Bereich, besonders wenn der Beton stark verdichtet wird, unter dem Druck aus. Auch das Ausschalen nach dem Aushärten des Betons ist sehr zeitaufwendig und erfordert die sortenreine Entsorgung verschiedenster Werkstoffe wie Polystyrol und kunststoffvergüteter Pappe.Formwork for supports or pillars is in the stand the technology has long been known and in use. They are used when creating a Structural, vertically oriented columns or erect columns. For this, they will be flat Formwork elements, e.g. B. of wood or metal, the desired Cross section merged accordingly and with suitable clamping devices, for example Screw clamps, fixed relative to each other. Because of the hydrostatic pressure of the liquid concrete inside the column formwork is very high, it can be up to 60 kN per square meter, it is necessary that the tensioners accordingly are designed, as well as the formwork elements over a have sufficient stability. The creation this formwork on site is very time consuming and expensive. Have been around for some Time known formwork tubes made of impregnated cardboard, the one to create a column with a rectangular one or square cross-section on the inside foamed with a corresponding cross-section of polystyrene are. This formwork, essentially consist of a cardboard tube, but bulge in their lower area, especially if the concrete is heavily compressed under the pressure. Also is stripping after the concrete has hardened very time consuming and requires single-variety Disposal of various materials such as polystyrene and plastic-coated cardboard.
Ausgehend vom Stand der Technik hat sich die Erfindung zur Aufgabe gestellt, eine Schalung zur Errichtung einer Säule oder einer Stütze eines Bauwerks zur Verfügung zu stellen, die auch bei einer großen Höhe der Säule über ausreichende statische Festigkeit verfügt, die nach dem Aushärten entweder zum Bestandteil des Gußteils wird oder in einfacher Weise sortenrein entsorgbar ist, sowie die Schalung kostengünstig und schnell erstellbar ist.Based on the prior art, the invention tasked with formwork for erection a pillar or column of a building to make available, even at a great height of the column over sufficient static Having strength after curing either becomes part of the casting or in simpler Is disposable, as well as the formwork is inexpensive and quick to create.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Schalelemente eine Schicht aus Faserzement aufweisen, die Spannvorrichtung aus einer an den Schalelementen außenseitig horizontal verlaufenden Umfassung und einem darum umlaufenden Metallband mit einer Zugvorrichtung besteht.According to the invention, this object is achieved by that the formwork elements a layer of fiber cement have the clamping device from one to the Formwork elements running horizontally on the outside Enclosure and a surrounding metal band with a pulling device.
Der Kerngedanke der Erfindung besteht darin, daß die Schalelemente zur Errichtung einer Säulenschalung zumindest eine Schicht aus Faserzement aufweisen. Dieser Werkstoff verfügt über eine ausreichende mechanische Stabilität, um dem großen hydrostatischen Druck des Betons entgegenzuwirken bzw. sich nicht zu verformen. Desweiteren kann, wie weiter unten ausgeführt, das Schalelement in einfacher Weise nach dem Aushärten entfernt werden oder wird zum Bestandteil des Gußelementes. Zur relativen Festlegung der einzelnen Schalelemente zueinander dient eine Spannvorrichtung, die im wesentlichen aus einem horizontal umlaufenden Metallband mit einer Zugvorrichtung besteht. Damit das relativ schmale Metallband, besonders im Bereich der Ecken, sich nicht in das Faserzementmaterial einschneidet und dieses beschädigt, wird zwischen Metallband und Schalelement eine ebenfalls horizontal verlaufende Umfassung angeordnet. Unter diesem Begriff sind hierbei, wie weiter unten beschrieben, quaderförmige Bauteile zu verstehen, deren Breite wesentlich größer ist als die Breite des Metallbandes und damit den auf sie ausgeübten Druck auf einer größeren Fläche an das Schalelement weitergeben. Bei einer Säule mit rechteckigem Querschnitt wird an jeder Seite ein solches Bauteil zwischen Metallband und Faserzementplatte eingebracht, wobei deren Erstreckung in horizontaler Richtung im wesentlichen der Breite des jeweiligen Schalungselements entspricht. Das Material, aus dem die Umfassung besteht, kann wie weiter unten dargestellt, gewählt werden. Das Metallband wird mit einer beliebig wählbaren Zugvorrichtung verkürzt, um es auf die Umfassung zu pressen und damit allseitigen, gleichmäßigen Druck auf die Schalungskonstruktion auszuüben. Selbstverständlich werden über die Höhe der Säulenschalung verteilt mehrere Spannvorrichtungen angeordnet werden, um eine gleichmäßig abgestützte Konstruktion zu erhalten. The main idea of the invention is that the formwork elements for erecting a column formwork have at least one layer of fiber cement. This material has sufficient mechanical stability to the large hydrostatic To counteract pressure of the concrete or not to deform. Furthermore, how can executed below, the formwork element in simpler Way after curing or will be removed part of the cast element. For relative Definition of the individual formwork elements to each other serves a jig that essentially from a horizontal metal band with a Draw device exists. So that is relative narrow metal band, especially around the corners, does not cut into the fiber cement material and this damaged, is between the metal band and Formwork element also a horizontal one Surrounding arranged. Are under this term here, as described below, cuboid To understand components whose width is essential is larger than the width of the metal strip and thus the pressure on them on a larger one Pass the surface to the formwork element. At a Rectangular cross-section will be on each Such a component between the metal strip and Fiber cement board introduced, the extent of which in the horizontal direction essentially the Width of the respective formwork element corresponds. The material from which the enclosure is made can as shown below. The Metal strip is made with any pulling device shortened it to the embrace press and thus all-round, even pressure to exert on the formwork construction. Of course are about the height of the column formwork several clamping devices are arranged, for an evenly supported construction to obtain.
Der Vorteil der Erfindung besteht darin, daß nach dem Aushärten des Betons die Spannvorrichtung in einfacher Weise entfernbar ist, beispielsweise mittels des Durchtrennens des Metallbandes, und die einzelnen Bestandteile in einfacher Weise entsorgt oder im Falle der Umfassungen wieder verwendet werden können. Die Schalelemente können, wie bereits ausgeführt, ebenfalls entsorgt oder wiederverwendet werden oder sie verbleiben am Gußteil. Desweiteren ist es möglich, Säulenschalungen entsprechenden Querschnitts und Höhe werkseitig herzustellen, die Schalungen an der Baustelle anzuliefern, dort aufzustellen und mit Beton auszugießen. Damit wird eine erhebliche Beschleunigung sowie eine Verbilligung bei der Errichtung von Säulen oder Stützen erreicht. Die Befestigung der Schalung auf dem Untergrund kann in vielfältiger, dem Fachmann bekannter, Weise erfolgen.The advantage of the invention is that after the hardening of the concrete is easily removable, for example by means of cutting the metal strip, and the disposed of individual components in a simple manner or be used again in the case of the enclosures can. The formwork elements can, as already executed, also disposed of or reused will or remain on the casting. Furthermore it is possible to corresponding column formwork Cross-section and height to manufacture at the factory Deliver formwork to the construction site, set it up there and pour with concrete. So that will a considerable acceleration and a reduction in price achieved during the erection of columns or supports. The formwork is fastened to the subsurface can be used in many different ways Way.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Advantageous embodiments of the invention are the subject of subclaims.
Das Material der Umfassung muß hart genug sein, um den vom Metallband auf sie ausgeübten Druck ohne wesentliche Verformung aufnehmen und ihn an das darunterliegende Schalelement weitergeben zu können. Es wird vorgeschlagen, Umfassungen aus Hartholz, wie beispielsweise Pockholz, Eiche oder Rubinie herzustellen. Alternativ dazu kann die Umfassung auch aus einem Hartkunststoff, wie beispielsweise PVC, hergestellt werden. Damit wird eine praktisch beliebig häufige Wiederverwendung der Umfassung ermöglicht.The material of the enclosure must be hard enough to the pressure exerted on them by the metal band without absorb significant deformation and attach it to the to be able to pass on the underlying formwork element. It is suggested hardwood enclosures, such as pockwood, oak or ruby to manufacture. Alternatively, the enclosure also from a hard plastic, such as PVC. So that becomes a practically unlimited reuse of the enclosure enables.
Als Zugverbindung für das Metallband wird eine im Stand der Technik bekannte Schnellspannvorrichtung oder eine Schraubverbindung vorgeschlagen, bei der mit Hilfe einer Verschraubung die Länge des Metallbandes verkürzt und damit der auf die Umfassung bzw. die Schalelemente ausgeübte Druck erhöht wird. Eine ausreichende Dimensionierung der Zugvorrichtung bzw. deren Verbindung mit dem Metallband ist dem Fachmann auf vielfältige Weise möglich.As a train connection for the metal band, an im Quick release device known in the art or proposed a screw connection in which with the help of a screw connection the length of the metal band shortened and thus the outline or the formwork elements applied pressure is increased. Adequate dimensioning of the pulling device or their connection to the metal band possible for the expert in many ways.
Besonders bei Säulen mit rechteckigem Querschnitt wird die Umfassung aus vier quaderförmigen Bauteilen bestehen, deren horizontale Abmessung im wesentlichen der jeweiligen horizontalen Erstreckung des Schalelementes, an dem sie anliegend, entspricht. Dies ist in den Figuren weiter unten beispielhaft dargestellt. Dabei ist es unerheblich, ob sich die benachbarten Teile der Umfassung, im Eckbereich, unmittelbar berühren, oder sie geringfügig voneinander beabstandet sind. Sie sind derart ausgelegt, daß sie breiter als das relativ schmale Metallband sind, um die Auflagefläche auf dem Schalelement zur vergrößern. Außerdem wird mit ihnen verhindert, daß das unter Zug stehende Metallband im Eckbereich in das Faserzementmaterial einschneidet. Ihre Länge, d. h. horizontale Abmessung, kann auch so gewählt werden, daß sie über das Schalelement seitlich hinausragen, wie ebenfalls in den Figuren dargestellt.Especially for columns with a rectangular cross-section the enclosure is made up of four cuboid components exist, their horizontal dimension essentially the respective horizontal extension of the formwork element to which it is attached. This is exemplified in the figures below shown. It is irrelevant whether the neighboring parts of the enclosure, in the corner area, touch immediately, or slightly are spaced from each other. They are designed that it is wider than the relatively narrow metal band are to the bearing surface on the formwork element to enlarge. Besides, with them prevents the metal band under tension cuts into the fiber cement material in the corner area. Your length, d. H. horizontal dimension, can can also be chosen so that they over the formwork element protrude laterally, as also in the figures shown.
Bei Säulen, die an der Außenfläche einer Fassade angeordnet sind, kann es notwendig sein, Schalelemente mit einer Wärmedämmung zu versehen. Dazu ist vorgeschlagen, innenseitig, an der dem Beton zugewandten Seite des Schalelementes, eine wärmeisolierende Schicht, insbesondere aus extrudiertem Styrol, anzubringen. Dieses Material ist im Bauwesen zur Wärmedämmung wohl bekannt. Die Styrolschicht wird mit einem geeigneten Klebstoff mit der Faserzementplatte verbunden, damit sie sich während des Aushärtens des Betons nicht verschiebt. Dadurch wird das Schalelement zu einem Bestandteil des Gußteils. Nach dem Aushärten werden lediglich die Umfassungen und die Metallbänder entfernt. Eine Säule kann mit einer wärmedämmenden Schicht an einer oder mehreren Seiten ihres Querschnitts versehen werden.For columns that are on the outer surface of a facade are arranged, it may be necessary to formwork elements to be provided with thermal insulation. Is to suggested, inside, facing the concrete Side of the formwork element, a heat-insulating Layer, in particular of extruded styrene, to attach. This material is in construction well known for thermal insulation. The styrene layer with a suitable adhesive with the fiber cement board connected so that they can Curing of the concrete does not move. Thereby the formwork element becomes part of the casting. After curing, only the enclosures and removed the metal strips. A column can with a heat insulating layer on one or be provided on several sides of their cross section.
Um eine gleichmäßige Festlegung der Schalelemente relativ zueinander zu erhalten, werden mehrere Spannvorrichtungen im wesentlichen gleichmäßig über die Länge bzw. Höhe der Schalung verteilt angeordnet. Damit wird allseitig ein im wesentlichen gleichmäßige verteilter Druck ausgeübt. Der genaue Abstand der benachbarten Spannvorrichtungen kann je nach Höhe der Schalung bzw. deren Querschnittsfläche vom Fachmann gewählt werden.To ensure an even definition of the formwork elements to get relative to each other will be several Tensioning devices essentially evenly over the length or height of the formwork is distributed. This essentially becomes one on all sides evenly distributed pressure. The exact one Distance between the adjacent fixtures can vary according to the height of the formwork or its cross-sectional area be chosen by a specialist.
Zur Erhöhung der Stabilität des Bauwerks kann auch eine im wesentlichen bekannte Armierung in das Innere der Schalung eingebracht werden, um der Säule oder der Stütze eine erhöhte Druckbelastbarkeit bzw. eine größere Scherfestigkeit zu verleihen. Die Armierung kann sowohl lose in die Schalung eingebracht werden als auch mit geeigneten Vorrichtungen relativ zu den Schalelementen festgelegt werden, wie es dem Fachmann geläufig ist.To increase the stability of the structure can also an essentially known reinforcement inside the formwork to be brought to the column or the support has an increased pressure resistance or to give a greater shear strength. The Reinforcement can be placed loosely in the formwork be as well with suitable devices relative to the formwork elements, as is known to the expert.
Um die Schalelemente aus Faserzement wiederverwenden zu können wird, bevor sie zu einer Schalung zusammengesetzt werden, bzw. bevor sie mit Beton ausgegossen werden, ein Trennmittel innenseitig aufgebracht, um nach dem Aushärten das rückstandsfreie und einfache Ablösen vom Gußteil zu ermöglichen. Entsprechende Trennmittel sind im Baugewerbe bekannt. Ein Entfernen der Schalelemente kann auch notwendig sein, wenn es aus architektonischer Sicht gewünscht ist, eine unverblendete Säule zu haben.To reuse the formwork elements made of fiber cement to be able to put together a formwork before or before they are poured with concrete a release agent is applied on the inside, to leave the residue-free after curing and to allow easy detachment from the casting. Appropriate release agents are known in the construction industry. Removing the formwork elements can also be necessary if it is from an architectural point of view is desired to have an unpaved column.
Zur Erhöhung der Stabilität der Schalung können an den inneren Ecken, an denen jeweils zwei benachbarte Schalelemente aneinander anliegen, Dreikantleisten, insbesondere aus Kunststoff, befestigt werden. Eine solche Dreikantleiste, beispielsweise aus Hart-PVC, vergrößert die jeweilige Anlagefläche, und damit beispielsweise die Fläche, an der die Schalelemente miteinander verklebt werden.To increase the stability of the formwork can the inner corners, each with two adjacent ones Formwork elements abut each other, triangular strips, especially made of plastic become. Such a triangular strip, for example made of hard PVC, enlarges the respective contact surface, and thus, for example, the area on which the formwork elements are glued together.
Um den, in der Vertikalen betrachtet, nach unten zunehmenden hydrostatischen Druck des Betons aufnehmen zu können, wird vorgeschlagen, daß nach unten hin an der Säulenschalung mehr Spannvorrichtungen als an deren oberen Ende angeordnet werden, d. h., daß der gegenseitige Abstand benachbarter Spannvorrichtungen nach unten hin abnimmt. Die genaue Anordnung bzw. die Wahl geeigneter Abstände ist dem Fachmann möglich. Around that, viewed vertically, down absorb the increasing hydrostatic pressure of the concrete To be able to, it is suggested that down towards the column formwork more clamping devices than to be placed at the upper end thereof, d. that is, the mutual distance between neighboring Clamping devices decreases towards the bottom. The exact Arrangement or the choice of suitable distances is possible for the specialist.
Bei der werkseitigen Herstellung der Säulenschalungen können die einzelnen Schalelemente mit einem Klebstoff zusammengefügt werden. Insbesondere bei der Verwendung von Faserzementplatten wird die Verklebung mit einem nach dem Aushärten umweltneutralen PU-Kleber vorgeschlagen. Die erforderlichen Klebstoffe und die Ausführung der Klebeverbindungen sind dem Fachmann geläufig.During the factory manufacture of the column formwork can the individual formwork elements with a Glue are put together. Especially at The use of fiber cement panels becomes the bond with an environmentally neutral after curing PU adhesive suggested. The necessary Adhesives and the execution of the adhesive bonds are familiar to the expert.
Im Rahmen der Erfindung ist der Querschnitt einer Säule oder einer Stütze beliebig wählbar, sie wird jedoch besonders einen quadratischen oder rechteckigen Querschnitt aufweisen, die mit den stabilen Faserzementplatten in einfacher Weise realisierbar sind.In the context of the invention, the cross section is a Column or a support can be chosen arbitrarily, it will but especially a square or rectangular one Have cross-section that with the stable Fiber cement boards can be easily realized are.
Um während des Zusammenbaus der Schalung eine Verschiebung der Umfassung relativ zum Metallband zu verhindern, kann an ihrer Außenseite eine Nut entsprechender Breite zur Aufnahme des Bandes angebracht, z. B. eingefräst, werden.To make a shift during assembly of the formwork the enclosure relative to the metal band prevent, a groove on the outside corresponding Width to accommodate the tape, e.g. B. milled.
