Description
Die Erfindung betrifft ein Schalungselement als Bestandteil einer verlorenen Schalung für Industriefußböden aus Beton gemäß dem Oberbegriff des Anspruchs 1, wobei die Schalung im wesentlichen aus dem die Ränder eines Betonierfeldes schützenden Schalungselement sowie gegebenenfalls einer Unterlegfolie, Abstandhaltern, Gleitblechen und Gleitdübeln besteht, wobei das Schalungselement aus zwei gekanteten Profilen aus Metallblech besteht, deren in Einbaulage vertikal gerichtete Schenkel zueinander annähernd spaltlos angeordnet sind und deren horizontale Schenkel voneinander weg gerichtet sind und die Aufstandsfläche auf dem Untergrund bilden, wobei die freien Enden der vertikal gerichteten Schenkel rechtwinklig voneinander weg gerichtet abgekantet sind, so daß jedes Profil-Teilstück etwa U-förmig ausgebildet ist.The invention relates to a formwork element as part of a lost Formwork for industrial floors made of concrete according to the preamble of claim 1, wherein the Formwork essentially from the edges of a Concrete field protective formwork element as well if necessary a shim, spacers, Sliding plates and sliding dowels exist, which Formwork element made of two edged profiles Metal sheet is made, which is vertical in the installed position directed legs almost without gap to each other are arranged and their horizontal legs are directed away from each other and the Form a footprint on the ground, whereby the free ends of the vertically directed legs folded at right angles away from each other are so that each profile section is approximately U-shaped is trained.
Derartige Schalungselemente sind im Stand der Technik beispielsweise aus der EP-A-410079 bekannt. Solche Industriefußböden werden beispielsweise im Fahrbereich von Staplerfahrzeugen, anderen Fahrzeugen, insbesondere im Bereich in Regal- und Hochregalsystemen oder in Kühl- und Tiefkühlhallen eingesetzt. Wesentlich ist dabei, daß die einzelnen Betonfelder des Industriefußbodens annähernd spaltfrei aneinander angeschlossen werden, wobei durch die Schalungselemente ein Schutz der Ränder der Betonierfelder erreicht werden soll. Üblicherweise erfolgt der Aufbau eines solchen Industriefußbodens in der Weise, daß auf einen Untergrund eine Folie aufgebracht wird, auf die dann Schalungselemente aufgebracht werden. An den Schalungselementen sind Gleitdübel angeordnet, die die vertikalen Schenkel der Schalungselemente an hülsenartigen Ausbildungen durchsetzen. Die Schenkel jedes gekanteten Profils sind durch in Abstand angeordnete Steifen versteift. Quer zur Verlegerichtung der Schalungselemente werden Gleitbleche aufgelegt, auf die Abstandhalter in Form von Reitern aufgesetzt werden. Auf diese werden Betonstahlmatten aufgelegt. Anschließend wird das entsprechende Feld ausbetoniert, wobei jeweils ein L-förmiges Profil des Schalungselementes die Randkante des Betonierfeldes bildet. Als Beton wird vorzugsweise schwindungsarmer, hochfester Spezialbeton verwendet. Anschließend kann die Oberfläche des Betonierfeldes mit einer monolithischen Hartstoffbeschichtung versehen werden, die widerstandsfähig gegen rollende, schleifende oder schlagende Beanspruchungen ist. Such formwork elements are in the prior art Technology known for example from EP-A-410079. Such industrial floors are used, for example, in Driving range of forklift vehicles, others Vehicles, especially in the area of shelf and High-bay systems or in cold stores and freezers used. It is essential that the individual Approximately concrete fields of the industrial floor be connected to each other without gaps, whereby the formwork elements protect the edges the concrete fields should be reached. Usually such a structure is built Industrial flooring in such a way that on one A film is applied to the surface then formwork elements are applied. To the Formwork elements are arranged with sliding dowels the vertical legs of the formwork elements enforce sleeve-like formations. The Legs of each edged profile are through in Stiffeners spaced apart. Across Laying direction of the formwork elements Sliding plates placed on the spacers in Form of riders to be put on. To this reinforcing steel mats are placed. Subsequently the corresponding field is concreted, whereby each an L-shaped profile of the Formwork element the edge of the concrete field forms. As a concrete is preferred Low-shrinkage, high-strength special concrete used. Then the surface of the Concrete field with a monolithic Hard material coating can be provided resistant to rolling, grinding or striking stresses.
Durch diese Ausbildung wird schon weitestgehend ein Kantenschutz der Ränder des Betonierfeldes gebildet, so daß Beschädigungen der Randkanten des Betons nur in geringem Maße auftreten. Die Schalungselemente, die mit dem entsprechenden Betonmaterial des Betonierfeldes verbunden sind, können schwindungsbedingten Bewegungen des Betonierfeldes folgen, ohne daß es zu einem Abriß zwischen dem Beton und dem entsprechenden L-förmigen Profil kommt.This training is largely a Edge protection of the edges of the concrete field formed so that damage to the edge of the Concretes only occur to a small extent. The Formwork elements with the corresponding Concrete material of the concrete field are connected, can cause shrinking movements of the Concrete field follow without demolition between the concrete and the corresponding L-shaped Profile is coming.
Obwohl sich derartige Ausbildungen im Stand der Technik bewährt haben, besteht ein Bedarf dahingehend, noch einen verbesserten Kantenschutz für die Ränder des Betonierfeldes zu schaffen, wobei ein Ausbrechen des Betons im Anschluß an das Schalungselement unterbunden sein soll. Dabei soll die zwischen den benachbarten Schalungselementen gebildete Fuge zur Vermeidung von Rattermarken oder dergleichen beim Überfahren der Fugen relativ schmal ausgebildet sein. Im Prinzip soll eine nahezu fugenlose Ausbildung gewährleistet sein.Although such training in the state of the Have proven technology, there is a need in that, still an improved edge protection to create for the edges of the concrete field a breaking out of the concrete following the Formwork element should be prevented. In doing so between the neighboring formwork elements formed joint to avoid chatter marks or the like when driving over the joints relatively be narrow. In principle, one should almost seamless training can be guaranteed.
Ausgehend vom Oberbegriff des Anspruchs 1 ist diese Aufgabe erfindungsgemäß dadurch gelöst, daß auf der Außenseite der so gebildeten Profilenden ein im wesentlichen ebenflächiges Fugenabdeckprofil fixiert ist, daß das Fugenabdeckprofil aus zwei Flacheisen besteht, deren eines auf dem Profilende des ersten Profils fixiert ist und über den Fugenspalt bis über einen Teil des Profilendes des zweiten Profils greift und deren anderes auf dem Profilende des zweiten Profils fixiert ist, wobei beide Flacheisen in Sollage einen schmalen Fugenspalt zwischen ihren Stoßkanten einschließen:Starting from the preamble of claim 1, this is Problem solved according to the invention that on the outside of the so formed Profile ends are essentially flat Joint cover profile is fixed that the Joint cover profile consists of two flat bars, one on the profile end of the first profile is fixed and over the joint gap to over one Part of the profile end of the second profile engages and the other on the profile end of the second Profile is fixed, with both flat bars in Sollage a narrow gap between their Include butt edges:
Die entsprechenden U-förmigen Profile können aus geeignetem Metallblech gekantet werden, wobei als Ausgangsmaterial beispielsweise Stahlblech mit Korrosionsschutz oder auch Edelstahl zum Einsatz kommen kann. Die Ausbildung der Profile in Form von gekanteten Metallblechen ist wesentlich für die Ausbildung des Schalungselementes, da es zwar theoretisch möglich ist, gewalzte Profile einzusetzen, diese aber zu schwergewichtig sind, um eine manuelle Verlegung der Schalungselemente zu ermöglichen. Zudem wäre es bei gewalzten Profilen erforderlich, je nach Steghöhe des Profiles unterschiedliche Walzwerkzeuge vorzuhalten. Bei der Ausbildung der Profile aus gekantetem Metallblech können diese relativ leichtgewichtig ausgebildet werden, so daß die einzelnen Profilabschnitte von einer oder zwei Personen leicht handhabbar sind, wobei zudem eine Höhenänderung der Steghöhe bei gleichem Materialzuschnitt möglich ist. Dabei ändert sich lediglich die Schenkellänge, während die Steghöhe dann variabel ist. Es ist somit eine kostengünstige Fertigung und eine montagefreundliche Handhabung möglich.The corresponding U-shaped profiles can be made from suitable metal sheet can be folded, being as Starting material with sheet steel, for example Corrosion protection or stainless steel is used can come. The formation of profiles in the form of folded metal sheets is essential for that Training of the formwork element, as it is theoretically possible is rolled profiles use, but they are too heavy to manual laying of the formwork elements enable. It would also be the case with rolled profiles required, depending on the web height of the profile to hold different rolling tools. In the Forming the profiles from folded sheet metal can be made relatively lightweight are, so that the individual profile sections of one or two people are easy to handle, with a change in height of the web height same material cutting is possible. there only the leg length changes while the bridge height is then variable. So it's one inexpensive manufacturing and a assembly-friendly handling possible.
Dadurch, daß die einzelnen Teilstücke des Profiles U-förmig ausgebildet sind, wird erreicht, daß die Randkante jedes Betonierfeldes dauerhaft gegen Beschädigungen geschützt ist. Da es bei abgekanteten Profilen aus Metallblech nicht möglich ist, scharfe Kantungen am Übergang des Steges zu den Abwinklungen herzustellen, ist die Anordnung eines Fugenabdeckprofiles erforderlich. Durch dieses Fugenabdeckprofil kann die relativ breite Fuge zwischen den abgewinkelten Profilenden überdeckt werden, so daß nur eine äußerst schmale Fuge zwischen den einzelnen Betonierfeldern eingestellt wird.The fact that the individual sections of the profile Are U-shaped, it is achieved that the Edge of each concrete field permanently against Damage is protected. Since it is at folded metal sheet profiles not possible is sharp bends at the junction of the web Making the bends is the order a joint cover profile is required. By this joint cover profile can be the relatively wide Joint between the angled profile ends be covered so that only an extremely narrow Joint between the individual concrete fields is set.
Zudem werden gemäß dieser Ausbildung auf den abgekanteten Enden der Profilschenkel, die quasi in der Oberseite des Betonierfeldes liegen, Fugenabdeckprofile aus Flacheisen fixiert, wobei eines der beiden Flacheisen über den zwischen den benachbarten Profilen gebildeten Fugenspalt greift und das andere Flacheisen an dem anderen Profilendbereich parallel und flächenbündig zu dem ersten Flacheisen fixiert ist, so daß zwischen beiden Flacheisen eine schmale Fuge gebildet ist. Es wird hierdurch trotz der Ausbildung der Schalungselemente aus gekanteten Profilen aus Metallblech eine exakte und enge Fugenausbildung gewährleistet. In addition, according to this training folded ends of the profile legs, which are quasi in the top of the concrete field, Joint cover profiles made of flat iron fixed, whereby one of the two flat irons over the between the joint gap formed adjacent grips and the other flat iron at the other profile end area parallel and flush to the first Flat iron is fixed, so that between the two Flat iron a narrow joint is formed. It will this despite the training of Formwork elements made of folded profiles Metal sheet an exact and tight joint formation guaranteed.
Die Randkanten des Fugenabdeckprofiles können in dem fertig betonierten Betonfeld entweder flächenbündig in die Betonmasse eingebettet werden, oder aber, was bevorzugt ist, diese Fugenabdeckprofile stehen mit ihrer Blechstärke über die Oberfläche des Betonfeldes vor, wobei anschließend durch die monolithische Hartstoffbeschichtung der Oberseite des Betonierfeldes ein flächenbündiger Anschluß an die Fugenabdeckprofile erreicht wird.The edge of the joint cover profile can be in the finished concrete field either be embedded flush in the concrete mass, or, what is preferred, this Joint cover profiles are available with their sheet thickness over the surface of the concrete field, whereby then through the monolithic hard material coating the top of the concrete field flush connection to the joint cover profiles is achieved.
Um eine exakte und dauerhafte Anordnung der Fugenabdeckprofile an den jeweiligen Profilenden zu gewährleisten und einen Verzug der Profilenden zu vermeiden, an denen die Fugenabdeckprofile befestigt sind, ist vorgesehen, daß die Bestandteile des Fugenabdeckprofils im Auflagebereich auf dem jeweiligen Profilende Lochungen aufweisen und im Bereich der Lochungen mittels Durchstanzschweißen mit dem Profilende fest verbunden sind.To ensure an exact and permanent arrangement of the Joint cover profiles at the respective profile ends guarantee and a distortion of the profile ends avoid where the joint cover profiles are attached, it is provided that the Components of the joint cover profile in the Support area on the respective profile end Have perforations and in the area of the perforations by punching with the end of the profile are connected.
Gemäß dieser Ausbildung wird ein Verzug vermieden und es wird dennoch eine sichere und dauerhafte Halterung der Teile aneinander erreicht. Der jeweilige Schweißbereich kann anschließend glatt geflext oder glatt geschliffen werden, so daß störende Sichtbereiche oder dergleichen im Bereich der Schweißstellen vermieden sind.According to this training, a delay is avoided and it will still be a safe and lasting one Hold the parts together. The respective welding area can then be smooth be flexed or smoothed so that distracting viewing areas or the like in the area the welds are avoided.
Um insbesondere eine Vorfixierung der Fugenabdeckprofile an den jeweiligen Profilenden sicherzustellen, ist vorgesehen, daß die Bestandteile des Fugenabdeckprofils an den jeweiligen Profilenden angeheftet sind.In particular, a pre-fixation of the Joint cover profiles at the respective profile ends It is intended to ensure that the Components of the joint cover profile on the respective profile ends are pinned.
Auch beim Heften, beispielsweise mittels einer Schweißverbindung wird kein Verzug der Bestandteile des Profils oder dergleichen auftreten.Also when stapling, for example using a The welded joint does not distort the components of the profile or the like occur.
Bevorzugt ist zudem vorgesehen, daß die Wandstärke der Profile und/oder der Fugenabdeckprofile einige Millimeter beträgt, vorzugsweise etwa 2 mm bis 6 mm, insbesondere etwa 4 mm.It is also preferably provided that the wall thickness some of the profiles and / or joint cover profiles Is millimeters, preferably about 2 mm to 6 mm, in particular about 4 mm.
Die Wandstärke der Profile soll so bemessen sein, daß eine ausreichende Belastbarkeit der Profile gewährleistet ist, andererseits aber auch sichergestellt ist, daß die Profile mit beherrschbaren Kräften abgekantet werden können. Dabei hat sich eine Profilstärke von ca. 4 mm als besonders geeignet herausgestellt.The wall thickness of the profiles should be such that that the profiles are sufficiently resilient is guaranteed, but also on the other hand it is ensured that the profiles with controllable forces can be folded. This has a profile thickness of approx. 4 mm emphasized particularly suitable.
Um bei der Verlegung der Schalungselemente eine ordnungsgemäße Ausrichtung der Schalungselemente zueinander zu gewährleisten und dennoch die schwindungsbedingte Bewegung der Schalungselemente im mit Beton vergossenen Zustand zu gewährleisten, ist vorgesehen, daß die vertikalen Schenkel der Profile miteinander durch Verbindungsmittel, insbesondere Schraubbolzen mit Mutter, verbunden sind, die bei schwindungsbedingter Relativbewegung der betonierten Schalungselemente brechen oder reißen.In order to lay a proper alignment of the formwork elements to ensure each other and still the shrinkage-related movement of the formwork elements to ensure when poured with concrete, it is intended that the vertical legs of the Profiles with each other by connecting means, especially bolts with nut connected are those with relative movement due to shrinkage of the concrete formwork elements break or tear.
Die Verbindungsmittel können beispielsweise Kunststoffverbindungsmittel sein, die zur ordnungsgemäßen Verbindung der Profile geeignet und bestimmt sind, die aber nach dem Betonieren der Schalungselemente die schwindungsbedingte Relativbewegung nicht behindern, sondern bei Auftreten solcher Kräfte brechen oder reißen.The connecting means can for example Be plastic fasteners for proper connection of the profiles and are determined, but after concreting the Formwork elements the shrinkage-related Do not hinder relative movement, but at Such forces break or crack.
