Description

Schalungselement für Hohlbodenkonstruktionen Formwork element for hollow floor constructions
Die Erfindung betrifft ein Schalungselement für Hohlboden¬ konstruktionen 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-PS 29 30 426 ist es bekannt, den Oberboden aus Betonfertigteilen mit angegossenen Stützfüßen herzustellen. Der Transport der Betonfertigteile zur Baustelle verursacht hohe Kos.ten. Außerdem müssen die Fertigteile in aufwendiger Weise an den jeweiligen Bodengrundriß angepaßt werden. Zur Vermeidung dieser Nachteile ist es bekannt, den Esrrich für den Oberboden mit Hilfe einer verlorenen Schalung zu gießen. Gemäß der EP-PS 0 057 372 wird als verlorene Scha¬ lung eine Kunststoffolie verwendet, die tiefgezogene, topf- förmige 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 dementsprechend eine in die Kunststoffolie einstellbare begehbare Platte als Verlegehilfe an.From DE-PS 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. To avoid these disadvantages, it is known to pour the Esrrich 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 protrusions that form the supports during pouring. Pouring out the formwork consisting of the plastic film is difficult because 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 daß 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 installation.
Aus der EP 0 133 556 A2 ist ein Schalungselement der ein¬ gangs genannten Gattung 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 of the type mentioned at the outset is known which consists of a dimensionally stable plate, e.g. 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.
Der Erfindung liegt die Aufgabe zugrunde, ein begehbares Schalungselement für Hohlbodenkonstruktionen zur Verfügung zu stellen, das kostengünstig herstellbar ist, platzsparend transportiert werden kann und in einfacher Weise dem Boden- grundriß angepaßt werden kann.The object of the invention is to provide a walkable formwork element for hollow floor constructions which is inexpensive to manufacture, can be transported in a space-saving manner and can be adapted to the floor plan in a simple manner.
Diese Aufgabe wird bei einem Schalungselement der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teiles des Anspruches 1.In a formwork element of the type mentioned at the outset, this object is achieved according to the invention 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 formsta¬ bile 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 ausgebil¬ det sind, so daß die Töpfe bzw. die mit den Töpfen versehe- nen Platten ineinandergestapelt werden können. Auch das Verlegen der Schalung ist einfach, da die Platten entspre¬ chend 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. The formwork is also easy to lay, since 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, Hartfaser¬ platte, 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.
Zweckmäßigerweise werden die Töpfe lösbar, z.B. nach Art eines Bajonettverschlusses, mit Druckknopfverschlüssen, mit konischen Verschlüssen, mit Widerhakenverschlüssen oder mit Paßstiften an oder 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 Abfall¬ stücken wieder entfernt und weiterverwendet werden. Eine einfache Befestigung im Werk ist auch durch Einkleben der Töpfe möglich.The pots are expediently detachable, for example in the manner of a bayonet lock, with snap fasteners, with conical locks, with barbed locks or with Dowel pins attached to or in the cutouts of the plate, which on the one hand enables the pots to be quickly attached with a single handle and on the other hand results in a stable, captive, but detachable attachment. When the pots are attached at the factory, the pots can be removed from the waste pieces formed when the plates are cut and used again. 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.
Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Es zeigen :The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawing. Show it :

wie die Schnittdarstellung der Figur 4 zeigt, wird auf einen Unterboden oder eine Dämmung 10 eine verlorene Scha¬ lung 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 will be 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 Schalungselemen¬ ten 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 kreis¬ förmige 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 geschlos¬ sen.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 plate 18, which is preferably a chipboard, wood fiber, cellulose, biological, synthetic or plastic plate. 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.
Der Durchmesser der Töpfe 22 an ihrem oberen Rand 32 ent¬ spricht dem Durchmesser der Ausschnitte 20, so daß die Töpfe 22 mit geringem radialem Spiel in die Ausschnitte 20 einge- setzt werden können. Unterhalb ihres oberen Randes 32 weisen die Töpfe 22 einen horizontal nach außen stehenden Außen¬ flansch 24 auf. Werden die Töpfe 22 in die Ausschnitte 20 eingesetzt, so stützt sich die Platte 18 auf dem Außen¬ flansch 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 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 set. Below their upper edge 32, 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.
Unmittelbar an der Oberkante der Töpfe 22 sind in dem ersten Ausführungsbeispiei der Figuren 1 bis 3 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 der Materialstärke der Platte 18. Zum Einsetzen der Töpfe 22 in die Platte 18 werden die Nasen 26 mit den Umfangsaussparun- gen 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 Bajonettver¬ schlusses an der Platte 18 befestigbar.Immediately on the upper edge of the pots 22, in the first embodiment of FIGS. 1 to 3, three horizontally outwardly projecting lugs 26 which are arranged at the same angular distance from one another are formed. 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 the circumferential recesses 28 aligned so that the pots 22 can be inserted into the cutouts 20. When the outer flange 24 of the pot 22 * abuts the underside of the plate 18, the lugs 26 are located on the top of the plate 18 and can overlap the plate 18 by rotating the pot 22. In this way, the pots 22 can be fastened to the plate 18 in the manner of a bayonet lock.
In den Figuren 5 und 6 ist ein zweites Ausführungsbeispiel dargestellt. Soweit dieses mit dem ersten Ausführungsbei¬ spiel der Figuren 1 bis 3 übereinstimmt, sind dieselben Bezugszeichen verwendet und auf die vorangehende Beschrei- bung wird verwiesen.A second exemplary embodiment is shown in FIGS. 5 and 6. Insofar as this corresponds to the first exemplary embodiment in FIGS. 1 to 3, the same reference numerals are used and reference is made to the preceding description.
Im Ausführungsbeispiei der Figuren 5 und 6 sind auf dem Außenflansch 24 des Topfes 22 im Winkel gegeneinander ver- setzt Stifte 34 ang«=formt, die von dem Außenflansch 24 senkrecht nach oben ragen. In diesem Ausführungsbeispiei sind an dem oberen Rand 32 des Topfes 22 keine nach außen ragenden Nasen oder sonstige Vorsprünge oder Haken vorgese¬ hen. Außerhalb der Ausschnitte 20 sind in der Platte 18 in derselben Winkelanordnung wie die Stifte 34 Paßbohrungen 36 angebracht.In the exemplary embodiment of FIGS. 5 and 6, on the outer flange 24 of the pot 22, at an angle to one another, sets pins 34 ang «= forms that project vertically upward from the outer flange 24. In this embodiment, no outwardly projecting lugs or other projections or hooks are provided on the upper edge 32 of the pot 22. Outside the cutouts 20, fitting holes 36 are made in the plate 18 in the same angular arrangement as the pins 34.
Zur Befestigung der Töpfe 22 an den Ausschnitten 20 werden die Töpfe 22 von unten gegen die Platte 18 gedrückt, wobei der obere Rand 32 des Topfes 22 in den Ausschnitt 20 ein¬ greift und die Stifte 34 in diese Paßbohrungen 36 der Platte 18 eingedrückt werden. Die Stifte 34 werden kraftschlüssig in den Paßbohrungen 36 gehalten, so daß die Töpfe 22 an der Platte 18 befestigt sind. Durch Druck oder Schlag innen auf dem Boden der Töpfe 22 können diese wieder von der Platte 18 entfernt werden.To attach the pots 22 to the cutouts 20, the pots 22 are pressed against the plate 18 from below, the upper edge 32 of the pot 22 engaging in the cutout 20 and the pins 34 being pressed into these fitting bores 36 of the plate 18. The pins 34 are non-positively held in the fitting holes 36 so that the pots 22 are attached to the plate 18. By pressure or impact on the inside of the bottom of the pots 22, they can be removed again from the plate 18.
In diesem Ausführungsbeispiei dienen vor allem die Stifte 34 zur Befestigung der Töpfe 22 an der Platte 18, während der in den Ausschnitt 20 eingreifende obere Rand 32 des Topfes 22 für die Befestigung keine oder nur eine untergeordnete Rolle spielt. Der obere Rand 32 hat im wesentlichen die Aufgabe, die Innenkante der Platte 18 an dem Ausschnitt 20 gegen die eindringende Feuchtigkeit des Estrichs 14 abzu- decken, und erleichtert die Positionierung des Topfes 22 beim Einsetzen.In this exemplary embodiment, the pins 34 in particular serve for fastening the pots 22 to the plate 18, while the upper edge 32 of the pot 22 engaging in the cutout 20 plays no role or only a minor role for the fastening. The upper edge 32 essentially has the task of covering the inner edge of the plate 18 at the cutout 20 against the penetrating moisture of the screed 14 and facilitates the positioning of the pot 22 when it is inserted.
Um den kraftschlüssigen Halt der Stifte 34 in den Paßbohrun¬ gen 36 zu verstärken, können die Stifte 34 erforderlichen- falls nach Art eines Druckknopfverschlusses radial federnd auseinanderspreizbar ausgebildet sind. Ebenso ist es auch möglich, in die Paßbohrungen 36 metallische Buchsen einzu- setzer., die den Reibschluß erhöhen. Während beim Ausführungsbeispiei der Figuren 1 bis 3 die Bajonett-Verriegelung ein Drehen des Topfes 22 und damit einen kreisförmigen Querschnitt notwendig macht, kann im Ausführungsbeispiei der Figuren 5 und 6 der Topf 22 jede beliebige Querschnittsform aufweisen.In order to reinforce the non-positive hold of the pins 34 in the fitting bores 36, the pins 34 can, if necessary, be designed to be radially resiliently spread apart in the manner of a snap fastener. Likewise, it is also possible to insert 36 metallic bushings into the fitting bores, which increase the frictional engagement. While in the exemplary embodiment of FIGS. 1 to 3, the bayonet locking makes it necessary to turn the pot 22 and thus a circular cross section, in the exemplary embodiment of FIGS. 5 and 6 the pot 22 can have any desired cross-sectional shape.
Zur fugenlosen Verbindung aneinanderstoßender Schalungsele¬ mente sind Doppelnutleisten 30 aus Kunststoff oder derglei¬ chen vorgesehen. Die aneinanderstoßenden Platten 18 werden von beiden Seiten in die Nuten der Doppelnutleiste 30 ge- schoben, so daß diese Doppelnutleiste 30 die Platten 18 zusammenhält 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 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.
Nach dem Verlegen der Schalung wird diese mit dem flüssigen Estrich 14 übergössen 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 pots 22.
