Definitions
- the invention relates to a formwork element for hollow floor constructions according to the preamble of claim 1.
- Raised floors are used as industrial floors in order to be able to lay pipes, cables and the like in the floor. Hollow floors are also used for hypocaust heating.
- the hollow floors consist of a sub-floor and a screed supported by supporting elements with an upper floor.
- a formwork element which consists of a deep-drawn plate with bulges to form the supports.
- the board which is preferably made of cardboard, is likewise not accessible, so that the same difficulties arise during laying.
- a formwork element which consists of a dimensionally stable plate, e.g. B. plasterboard, exists and can be walked on to pour the screed material.
- Conical cutouts are provided in a grid in the plate, into which massive support feet are cast and held in a form-fitting manner.
- the transportation of the formwork elements provided with the support feet at the factory is complex.
- a formwork element for hollow floor constructions of the type specified in the preamble of claim 1 which consists of a dimensionally stable plate with cutouts into which supporting elements are inserted.
- the support elements are designed as dimensionally stable pots which rest on the underside of the plate with an outer flange which projects beyond the circumference of the cutout in order to support the plate.
- the pots are pressed or screwed into the cutouts with their upper edge for attachment to the plate.
- the attachment of the pots in the cutouts of the plate requires extremely high machining accuracy of the cutouts and the top edge of the pots. Deformations of the plate or pots, which are unavoidable under the rough conditions of the construction site, make it difficult or prevent the pots from being inserted into the cutouts. In practice, therefore, the pots can only be inserted into the plate at the factory.
- a prefabricated plastic plate is known as a wall or floor covering. Pot-shaped, dimensionally stable support elements are attached to the wall or floor to secure the plate. The plates are snapped onto these support elements, these snap into place with a flange protruding outwards at the top edge of the pot behind latching lugs of the plate. Since the support elements are first fastened to the wall or the floor and the plates are only snapped onto the fastened support elements, a high degree of accuracy is necessary when fastening the support elements to the wall or the floor, which makes the installation of the plates difficult. It is no longer possible to detach the plates from the support elements without destroying them.
- the invention has for its object to provide a walkable formwork element for hollow floor constructions, which is inexpensive to manufacture, can be transported in a space-saving manner and in which the support elements can also be used in a simple manner at the construction site.
- dimensionally stable pots are attached to the cutouts of the dimensionally stable plate.
- the plates and the pots can be transported separately to the construction site, the pots being inserted into the plate only on the spot.
- the pots can also be attached to the plate at the factory.
- a space-saving, inexpensive transport is possible in particular if the pots are frustoconical in shape with a circular, oval or polygonal cross section, so that the pots or the plates provided with the pots can be stacked one inside the other.
- Laying the formwork is also easy because the panels can be cut to fit the floor plan. If the pots are only used at the construction site, only the cut plate parts need to be filled with pots and not the resulting plate waste, which results in a cost saving.
- the pots can be produced inexpensively from plastic, preferably a recyclable plastic, or from biological or synthetic fiber material or cardboard.
- a wood chipboard, hardboard, cardboard, fiber or plastic board or the like is preferably used for the board, which is inexpensive and stable and can also meet all ecological requirements.
- the pots become detachable in the manner of a bayonet catch fixed in the cut-outs of the plate, which on the one hand enables the pots to be fastened with a single hand movement and on the other hand results in a stable, captive, but detachable fastening. If the pots are attached at the factory, the pots can be removed from the waste pieces created when the plates are cut and reused. A simple attachment in the factory is also possible by gluing in the pots.
- the plates are expediently connected to one another at their butt joints by means of double groove strips. This results in a tight connection of the panels for pouring with the liquid screed material. In this way, overlapping of the abutting plates can be avoided, which would lead to the formation of steps and additional material requirements. It is also possible to connect the panels using milled slots on the butt edges.
- a lost formwork 12 is placed on a sub-floor or insulation 10, which is described in more detail below.
- the lost formwork 12 is poured out with a liquid screed 14. After the screed has hardened, the top floor 16 is laid.
- the lost formwork 12 is composed of individual formwork elements, one of which is shown in FIG. 1.
- the formwork element consists of a rectangular one.
- the plate 18 has circular cutouts 20 arranged in a grid.
- Pots 22 made of dimensionally stable plastic or cardboard or biological or synthetic fiber material are inserted into the cutouts 20.
- the pots 22 have a frustoconical shape, are open on the upper surface with the larger diameter and closed on the bottom surface with the smaller diameter.
- the diameter of the pots 22 at their upper edge 32 corresponds to the diameter of the cutouts 20, so that the pots 22 are inserted into the cutouts 20 with little radial play can be.
- the pots 22 have a horizontally outwardly extending outer flange 24. If the pots 22 are inserted into the cutouts 20, the plate 18 is supported on the outer flange 24 of the pots 22.
- the edge 32 engaging in the cutout 20 of the plate 18 covers the inner edge of the cutout 20 with the liquid screed 14 during the later pouring.
- lugs 26 Located on the upper edge of the pots 22 are three horizontally outwardly projecting lugs 26 which are arranged at the same angular distance from one another.
- the lugs 26 correspond to three circumferential recesses 28 of the cutouts 20 which are arranged at the same angular distance.
- the vertical distance between the outer flange 24 and the lugs 26 of the pots 22 corresponds to the material thickness of the plate 18. To insert the pots 22 into the plate 18, the lugs 26 also become the peripheral recesses 28 aligned so that the pots 22 can be inserted into the cutouts 20.
- the lugs 26 are located on the top of the plate 18 and can overlap the plate 18 by rotating the pot 22.
- the pots 22 can be fastened in this way to the plate 18 in the manner of a bayonet catch.
- Double groove strips 30 made of plastic or the like are provided for the seamless connection of abutting formwork elements.
- the abutting plates 18 are pushed from both sides into the grooves of the double groove strip 30, so that this double groove strip 30 holds the plates 18 together and covers the butt joint in a sealing manner.
- the formwork After the formwork has been laid, it is poured over with the liquid screed 14 and, after the screed has hardened, forms the support plate for the top floor 16 which is supported by the poured-out pots 22.
Abstract
Description
Die Erfindung betrifft ein Schalungselement für Hohlbodenkonstruktionen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a formwork element for hollow floor constructions according to the preamble of claim 1.
Hohlböden werden als Industrieböden eingesetzt, um in dem Boden Rohleitungen, Kabel und dgl. verlegen zu können. Weiter werden Hohlböden für Hypokaustenheizungen verwendet. Die Hohlböden bestehen aus einem Unterboden und einem von Stützelementen getragenen Estrich mit Oberboden.Raised floors are used as industrial floors in order to be able to lay pipes, cables and the like in the floor. Hollow floors are also used for hypocaust heating. The hollow floors consist of a sub-floor and a screed supported by supporting elements with an upper floor.
Aus der DE-A-29 30 426 ist es bekannt, den Oberboden aus Betonfertigteilen mit angegossenen Stützfüßen herzustellen. Der Transport der Betonfertigteile zur Baustelle verursacht hohe Kosten. Außerdem müssen die Fertigteile in aufwendiger Weise an den jeweiligen Bodengrundriß angepaßt werden.From DE-A-29 30 426 it is known to produce the top floor from prefabricated concrete parts with cast support feet. Transporting the precast concrete parts to the construction site causes high costs. In addition, the finished parts have to be adapted in a complex manner to the respective floor plan.
Zur Vermeidung dieser Nachteile ist es bekannt, den Estrich für den Oberboden mit Hilfe einer verlorenen Schalung zu gießen. Gemäß der EP-PS 0 057 372 wird als verlorene Schalung eine Kunststoffolie verwendet, die tiefgezogene, topfförmige Auswölbungen aufweist, die beim Ausgießen die Stützen bilden. Das Ausgießen der aus der Kunststoffolie bestehenden Schalung ist schwierig, da die Kunststoffolie nicht begehbar ist. Die DE-OS 33 26 622 gibt demensprechend eine in die Kunststoffolie einstellbare begehbare Platte als Verlegehilfe an.To avoid these disadvantages, it is known to pour the screed for the top floor with the help of a lost formwork. According to EP-PS 0 057 372, a plastic film is used as the lost formwork, which has deep-drawn, pot-shaped bulges, which form the supports during pouring. Pouring out the formwork consisting of the plastic film is difficult since the plastic film cannot be walked on. DE-OS 33 26 622 accordingly specifies an adjustable walk-in plate in the plastic film as a laying aid.
Aus dem DE-GM 85 03 850 ist ein Schalungselement bekannt, das aus einer tiefgezogenen Platte mit Ausbauchungen zur Bildung der Stützen besteht. Die vorzugsweise aus Pappe bestehende Platte ist ebenfalls nicht begehbar, so das dieselben Schwierigkeiten bei dem verlegen auftreten.From DE-GM 85 03 850 a formwork element is known which consists of a deep-drawn plate with bulges to form the supports. The board, which is preferably made of cardboard, is likewise not accessible, so that the same difficulties arise during laying.
Aus der EP 0 133 556 A2 ist ein Schalungselement bekannt, das aus einer formstabilen Platte, z. B. Gipskarton, besteht und zum vergießen des Estrichmateriales begehbar ist. In der Platte sind in einem Raster konische Ausschnitte vorgesehen, in welche massive Stützfüße eingegossen und formschlüssig gehalten sind. Der Transport der werkseitig mit den Stützfüßen versehenen Schalungselemente ist aufwendig.From EP 0 133 556 A2 a formwork element is known which consists of a dimensionally stable plate, e.g. B. plasterboard, exists and can be walked on to pour the screed material. Conical cutouts are provided in a grid in the plate, into which massive support feet are cast and held in a form-fitting manner. The transportation of the formwork elements provided with the support feet at the factory is complex.
Aus der EP-A 0 416 411 ist ein Schalungselement für Hohlbodenkonstruktionen der im Oberbegriff des Anspruchs 1 angegebenen Gattung bekannt, das aus einer formstabilen Platte mit Ausschnitten besteht, in die Stützelemente eingesetzt sind. Die Stützelemente sind als formstabile Töpfe ausgebildet, die mit einem über dem Umfang des Ausschnittes hinausragenden Außenflansch an der Unterseite der Platte anliegen, um die Platte abzustützen. Die Töpfe sind zur Befestigung an der Platte mit ihrem oberen Rand in die Ausschnitte eingepreßt oder eingeschraubt. Die Befestigung der Töpfe in den Ausschnitten der Platte erfordert eine äußerst hohe Bearbeitungsgenauigkeit der Ausschnitte und des oberen Randes der Töpfe. Verformungen der Platte oder der Töpfe, wie sie unter den rauhen Bedingungen der Baustelle unvermeidlich sind, erschweren oder verhindern ein Einsetzen der Töpfe in die Ausschnitte. Die Töpfe können daher in der Praxis nur werkseitig in die Platte eingesetzt werden.From EP-A 0 416 411 a formwork element for hollow floor constructions of the type specified in the preamble of claim 1 is known, which consists of a dimensionally stable plate with cutouts into which supporting elements are inserted. The support elements are designed as dimensionally stable pots which rest on the underside of the plate with an outer flange which projects beyond the circumference of the cutout in order to support the plate. The pots are pressed or screwed into the cutouts with their upper edge for attachment to the plate. The attachment of the pots in the cutouts of the plate requires extremely high machining accuracy of the cutouts and the top edge of the pots. Deformations of the plate or pots, which are unavoidable under the rough conditions of the construction site, make it difficult or prevent the pots from being inserted into the cutouts. In practice, therefore, the pots can only be inserted into the plate at the factory.
Aus der FR-A 2 482 990 ist eine vorgefertigte Kunststoffplatte als Wand- oder Bodenverkleidung bekannt. Zur Befestigung der Platte werden topfförmige formstabile Stützelemente an der Wand bzw. dem Boden befestigt. Die Platten werden auf diese Stützelemente aufgeschnappt, wobei diese mit einem am oberen Topfrand nach außen ragenden Flansch hinter Rastnasen der Platte einrasten. Da die Stützelemente zunächst an der Wand bzw. dem Boden befestigt werden und die Platten erst auf die befestigten Stützelemente aufgeschnappt werden, ist eine hohe Genauigkeit bei der Befestigung der Stützelemente an der Wand bzw. dem Boden notwendig, was die Verlegung der Platten schwierig macht. Ein Lösen der Platten von den Stützelementen ist ohne Zerstörung nicht mehr möglich.From FR-A 2 482 990 a prefabricated plastic plate is known as a wall or floor covering. Pot-shaped, dimensionally stable support elements are attached to the wall or floor to secure the plate. The plates are snapped onto these support elements, these snap into place with a flange protruding outwards at the top edge of the pot behind latching lugs of the plate. Since the support elements are first fastened to the wall or the floor and the plates are only snapped onto the fastened support elements, a high degree of accuracy is necessary when fastening the support elements to the wall or the floor, which makes the installation of the plates difficult. It is no longer possible to detach the plates from the support elements without destroying them.
Der Erfindung liegt die Aufgabe zugrunde, ein begehbares Schalungselement für Hohlbodenkonstruktionen zur Verfügung zu stellen, das kostengünstig herstellbar ist, platzsparend transportiert werden kann und bei dem die Stützelemente in einfacher Weise auch an der Baustelle eingesetzt werden können.The invention has for its object to provide a walkable formwork element for hollow floor constructions, which is inexpensive to manufacture, can be transported in a space-saving manner and in which the support elements can also be used in a simple manner at the construction site.
Diese Aufbabe wird bei einem Schalungselement der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teiles des Anspruches 1.This task is solved according to the invention in a formwork element of the type mentioned at the outset by the features of the characterizing part of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Bei dem erfindungsgemäßen Schalungselement werden formstabile Töpfe an den Ausschnitten der formstabilen Platte befestigt. Die Platten und die Töpfe können getrennt zur Baustelle transportiert werden, wobei erst an Ort und Stelle die Töpfe in die Platte eingesetzt werden. Ebenso können die Töpfe bereits im Werk in der Platte befestigt werden. Ein platzsparender kostengünstiger Transport ist insbesondere möglich, wenn die Töpfe kegelstumpfförmig mit kreisrundem, ovalem oder vieleckigem Querschnitt ausgebildet sind, so daß die Töpfe bzw. die mit den Töpfen versehenen Platten ineinandergestapelt werden können. Auch das Verlegen der Schalung ist einfach, da die Platten entsprechend dem Bodengrundriß zugeschnitten werden können. Werden die Töpfe erst an der Baustelle eingesetzt, brauchen nur die zugeschnittenen Plattenteile und nicht der entstehende Plattenabfall mit Töpfen besetzt zu werden, wodurch sich eine Kosteneinsparung ergibt.In the formwork element according to the invention, dimensionally stable pots are attached to the cutouts of the dimensionally stable plate. The plates and the pots can be transported separately to the construction site, the pots being inserted into the plate only on the spot. The pots can also be attached to the plate at the factory. A space-saving, inexpensive transport is possible in particular if the pots are frustoconical in shape with a circular, oval or polygonal cross section, so that the pots or the plates provided with the pots can be stacked one inside the other. Laying the formwork is also easy because the panels can be cut to fit the floor plan. If the pots are only used at the construction site, only the cut plate parts need to be filled with pots and not the resulting plate waste, which results in a cost saving.
Die Töpfe sind kostengünstig aus Kunststoff, vorzugsweise einem recycling-fähigen Kunststoff, oder aus biologischem oder synthetischem Faserstoff oder Karton, herstellbar. Für die Platte wird vorzugsweise eine Holzspanplatte, Hartfaserplatte, Karton-, Faser- oder Kunststoffplatte oder ähnliches verwendet, die preisgünstig und stabil ist und auch allen ökologischen Anforderungen genügen kann.The pots can be produced inexpensively from plastic, preferably a recyclable plastic, or from biological or synthetic fiber material or cardboard. A wood chipboard, hardboard, cardboard, fiber or plastic board or the like is preferably used for the board, which is inexpensive and stable and can also meet all ecological requirements.
Die Töpfe werden lösbar nach Art eines Bajonettverschlusses in den Ausschnitten der Platte befestigt, was einerseits ein schnelles Befestigen der Töpfe mit einem einzigen Handgriff ermöglicht und andererseits eine stabile unverlierbare, aber jederzeit lösbare BeFestigung ergibt. Bei werkseitiger Befestigung der Töpfe können dabei die Töpfe aus den beim Zuschnitt der Platten enstehenden Abfallstücken wieder entfernt und weiterverwendet werden. Eine einfache Befestigung im Werk ist auch durch Einkleben der Töpfe möglich.The pots become detachable in the manner of a bayonet catch fixed in the cut-outs of the plate, which on the one hand enables the pots to be fastened with a single hand movement and on the other hand results in a stable, captive, but detachable fastening. If the pots are attached at the factory, the pots can be removed from the waste pieces created when the plates are cut and reused. A simple attachment in the factory is also possible by gluing in the pots.
Die Platten werden zweckmäßigerweise an ihren Stoßfugen mittels Doppelnutleisten miteinander verbunden. Dadurch ergibt sich eine dichte Verbindung der Platten für das Ausgießen mit dem flüssigen Estrichmaterial. Es können dadurch Überlappungen der aneinander anstoßenden Platten vermieden werden, die zu Stufenbildung und zusätzlichem Materialbedarf führen würden. Auch eine Verbindung der Platten durch eingefräßte Schlitze an den Stoßkanten ist möglich.The plates are expediently connected to one another at their butt joints by means of double groove strips. This results in a tight connection of the panels for pouring with the liquid screed material. In this way, overlapping of the abutting plates can be avoided, which would lead to the formation of steps and additional material requirements. It is also possible to connect the panels using milled slots on the butt edges.

Wie die Schnittdarstellung der Figur 4 zeigt, wird auf einen Unterboden oder eine Dämmung 10 eine verlorene Schalung 12 gelegt, die nachfolgend näher beschrieben wird. Die verlorene Schalung 12 wird mit einem flüssigen Estrich 14 ausgegossen. Nach dem Erhärten des Estriches wird der Oberboden 16 verlegt.As the sectional view in FIG. 4 shows, a lost formwork 12 is placed on a sub-floor or insulation 10, which is described in more detail below. The lost formwork 12 is poured out with a liquid screed 14. After the screed has hardened, the top floor 16 is laid.
Die verlorene Schalung 12 ist aus einzelnen Schalungselementen zusammengesetzt, von denen eines in Figur 1 dargestellt ist. Das Schalungselement besteht aus einer rechteckigen. Platte 18, die vorzugsweise eine Holzspan-, Holzfaser-, Zellstoff-, biologische, synthetische oder Kunststoffplatte ist. Die Platte 18 weist in einem Raster angeordnete kreisförmige Ausschnitte 20 auf. In die Ausschnitte 20 sind aus formstabilem Kunststoff oder Karton oder biologischem oder synthetischem Faserstoff bestehende Töpfe 22 eingesetzt. Die Töpfe 22 weisen eine kegelstumpfförmige Gestalt auf, sind an ihrer oberen Fläche mit dem größeren Durchmesser offen und an ihrer Bodenfläche mit dem kleineren Durchmesser geschlossen.The lost formwork 12 is composed of individual formwork elements, one of which is shown in FIG. 1. The formwork element consists of a rectangular one.
Der Durchmesser der Töpfe 22 an ihrem oberen Rand 32 entspricht dem Durchmesser der Ausschnitte 20, so daß die Töpfe 22 mit geringem radialem Spiel in die Ausschnitte 20 eingesetzt werden können. Unterhalb ihres oberen Randes 32 weisen die Töpfe 22 einen horizontal nach außen stehenden Außenflansch 24 auf. Werden die Töpfe 22 in die Ausschnitte 20 eingesetzt, so stützt sich die Platte 18 auf dem Außenflansch 24 der Töpfe 22 ab. Der in den Ausschnitt 20 der Platte 18 eingreifende Rand 32 deckt die Innenkante des Ausschnittes 20 beim späteren Ausgießen mit dem flüssigen Estrich 14 ab.The diameter of the
Unmittelbar an der Oberkante der Töpfe 22 sind drei in gleichem Winkelabstand zueinander angeordnete horizontal nach außen abstehende Nasen 26 angeformt. Den Nasen 26 entsprechen drei im gleichen Winkelabstand angeordnete Umfangsaussparungen 28 der Ausschnitte 20. Der vertikale Abstand zwischen dem Außenflansch 24 und den Nasen 26 der Töpfe 22 entspricht dar Materialstärke der Platte 18. Zum Einsetzen der Töpfe 22 in die Platte 18 werden die Nasen 26 mit den Umfangsaussparungen 28 ausgerichtet, so daß die Töpfe 22 in die Ausschnitte 20 eingesetzt werden können. Wenn der Außenflansch 24 des Topfes 22 an der Unterseite der Platte 18 anliegt, befinden sich die Nasen 26 an der Oberseite der Platte 18 und können durch Verdrehen des Topfes 22 die Platte 18 übergreifen. Die Töpfe 22 sind auf diese Weise nach Art eines Bajonettverschlusses an der Platte 18 befestigbar.Immediately on the upper edge of the
Zur fugenlosen Verbindung aneinanderstoßender Schalungselemente sind Doppelnutleisten 30 aus Kunststoff oder dergleichen vorgesehen. Die aneinanderstoßenden Platten 18 werden von beiden Seiten in die Nuten der Doppelnutleiste 30 geschoben, so daß diese Doppelnutleiste 30 die Platten 18 zusammenhäit und die Stoßfuge dichtend abdeckt.Double groove strips 30 made of plastic or the like are provided for the seamless connection of abutting formwork elements. The abutting
Nach dem Verlegen der Schalung wird diese mit dem flüssigen Estrich 14 übergossen und bildet nach dem Erhärten des Estriches die durch die ausgegossenen Töpfe 22 abgestützte Trägerplatte für den Oberboden 16.After the formwork has been laid, it is poured over with the liquid screed 14 and, after the screed has hardened, forms the support plate for the top floor 16 which is supported by the poured-out
