Description
Wahlweise verbleibender oder wiedergewinnbarer, gewölbter Schalkörper für Stahlbetonrippendecken od. dgl. Die Erfindung betrifft einen wahlweise verbleibenden oder wiedergewinnbaren gewölbten Schalkörper mit vorzugsweise trogartigem Querschnitt für Stahlbetonrippendecken od. dgl., der aus Hartfaserplatten, Sperrholz oder ähnlichen Baustoffen gefertigt ist.Optionally remaining or recoverable, arched shell body for reinforced concrete rib ceilings od. The like. The invention relates to an optional remaining or recoverable arched shell body with a preferably trough-shaped cross-section for reinforced concrete rib ceilings or the like. Made of hardboard, plywood or the like Building materials is made.
Hartfaserplatten, Sperrholz und andere Baustoffe mit etwa gleichen Eigenschaften, wie die bezeichneten sie aufweisen, werden hauptsächlich dann für Schalkörper verwendet, wenn der Schalkörper in der Decke verbleiben soll, da diese Baustoffe preisgünstig sind und somit Kosten eingespart werden.Hardboard, plywood and other building materials with about the same Properties, as they have been designated, are mainly used for Shutter body used when the shell body is to remain in the ceiling, as this Building materials are inexpensive and thus costs are saved.
Diese Baustoffe haben jedoch den Nachteil, daß sie elastisch verformbar sind, weshalb die aus ihnen gebildeten Schalkörper ausgesteift werden müssen, was zusätzlich Kosten verursacht.However, these building materials have the disadvantage that they are elastically deformable are, which is why the shell bodies formed from them must be stiffened, what causes additional costs.
Es sind zwar bereits Schalkörper aus Sperrholz bekannt, die nicht ausgesteift werden. Diese bekannten Schalkörper werden im ebenen Zustand an die Baustelle transportiert und dort erst beim Einsetzen in die Schalung in die gewünschte Wölbung gebogen. Damit dieses Verfahren möglich ist, muß das für den Schalkörper verwendete Sperrholz in seiner Dicke so weit beschränkt sein, daß es ohne weiteres in die gewölbte Form gebogen werden kann, was bei den eingesetzten Schalkörpern auch hier den bekannten Nachteil der elastischen Verformbarkeit bringt, so daß er ebenfalls nicht biegesteif ist. Er ist - da aus diesem Grunde schlecht beaehbar - für die in der Schalung beschäftigten Arbeiter hinderlich. Außerdem weicht die in eine gewölbte Form gebrachte Sperrplatte dieser Schalkörper gegebenenfalls beim Einbringen des Betons in die Schalung aus, so daß ein unregelmäßiges Deckenprofil entsteht, was die Nachteile mit sich bringt, daß gegebenenfalls die statischen Verhältnisse nicht mehr vollständig mit den theoretisch errechneten übereinstimmen und daß die Deckenuntersicht aus architektonischen Gründen nicht sichtbar bleiben kann.There are already plywood shell bodies known that are not stiffened. These known formwork bodies are transported to the construction site in a flat state and are only bent into the desired curvature when they are inserted into the formwork. So that this method is possible, the plywood used for the shell body must be so limited in its thickness that it can be easily bent into the curved shape, which brings the known disadvantage of elastic deformability in the shell bodies used here too, so that it is also not rigid. It is - because it is difficult to monitor for this reason - a hindrance for the workers employed in the formwork. In addition, the curved barrier plate of this formwork body evades when the concrete is poured into the formwork, so that an irregular ceiling profile is created, which has the disadvantages that the static conditions may no longer completely match the theoretically calculated ones and that the ceiling soffit cannot remain visible for architectural reasons.
Bei einem anderen Schalkörper der vorgenannten Art werden zwar wahlweise zwei eingespannte, ohne Abstand zueinander angeordnete Furnierplatten verwendet; jedoch wird damit die elastische Verformbarkeit kaum gemildert. Außerdem müssen bei diesem Schalkörper in der Schalung besonders geformte Querbretter als Widerlager für die Schalkörper befestigt werden.In another shell of the aforementioned type, although optional two clamped veneer panels arranged without spacing are used; however, the elastic deformability is hardly impaired thereby. Also have to In this formwork body, specially shaped transverse boards as abutments in the formwork for the shell body to be attached.
Der Erfindung liegt die Aufgabe zugrunde, den gewölbten Schalkörper der eingangs näher beschriebenen Art derart zu verbessern, daß auf eine Aussteifung verzichtet werden kann, ohne daß die damit verbundenen Nachteile in Kauf genommen werden müssen. Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der Schalkörper aus mindestens zwei in der gewölbten Form miteinander verleimten Platten besteht.The invention is based on the object of the curved shell body to improve the type described in more detail in such a way that on a stiffening can be dispensed with without the associated disadvantages being accepted Need to become. This object is achieved according to the invention in that the shell body consists of at least two panels glued together in the curved shape.
Bei einem derart gefertigten Schalkörper weist zwar jede einzelne Platte noch die zum Formen nötige Elastizität auf, jedoch wird durch das Verleimen der Platten in der gewölbten Form eine Steifigkeit erzielt, die den auf der Baustelle gegebenen Anforderungen genügt, so daß Aussteifungen oder ein Einspannen der Schalkörper nicht mehr erforderlich sind, wodurch Kosten eingespart werden.In the case of a shell body manufactured in this way, each individual The board still has the elasticity required for molding, but is achieved by gluing The arched shape of the panels achieves a rigidity that matches that of the construction site given requirements is sufficient, so that stiffeners or a clamping of the shell body are no longer required, which saves costs.
Im allgemeinen wird als Baustoff für die Schalkörper einer der als preisgünstig bekannten geeigneten Baustoffe, wie Hartfaserplatten, Furnierplatten usw., Verwendung finden. Es können jedoch auch Platten aus anderem Werkstoff, beispielsweise aus Kunststoff, verwendet werden, sofern diese Stoffe preisgünstig sind und die für den in Frage stehenden Zweck erforderlichen Eigenschaften besitzen.In general, one of the as a building material for the shell body is used inexpensive known suitable building materials, such as hardboard, veneer panels etc., find use. However, plates made of another material, for example made of plastic, provided that these substances are inexpensive and the have properties required for the purpose in question.
Bei in der Decke verbleibenden gewölbten Schalkörpern kann zumindest eine der Platten in an sich bekannter Weise aus einem Isolierstoff bestehen, so daß eine gesonderte Wärmeisolierung nicht mehr erforderlich ist. Es kann auch vorteilhaft zumindest die im gewölbten Schalkörper innenliegende Platte aus einem Schallschluckstoff bestehen oder z. B. durch Lochung od. dgl. schalldämpfend ausgebildet sein. Diese Maßnahmen können jede für sich oder auch zusammen angewendet werden.In the case of arched formwork bodies remaining in the ceiling, at least one of the plates consist of an insulating material in a manner known per se, so that a separate thermal insulation is no longer required. It can also be beneficial at least the plate made of a sound-absorbing material inside the curved shell body exist or z. B. od by perforation. Like. Be formed sound-absorbing. These Measures can be used individually or together.
In der Zeichnung ist eine Ausführungsbeispiel des Schalkörpers nach der Erfindung dargestellt. Es zeigt F i g. 1 einen Schalkörper in schaubildlicher Darstellung und F i g. 2 den Schalkörper in eine Sparschalung eingesetzt in einem' Querschnitt (Ausschnitt).In the drawing, an embodiment of the shell body according to the invention is shown. It shows F i g. 1 a shell body in a diagrammatic representation and FIG . 2 the formwork inserted in a formwork in a 'cross-section (cutout).
Der Schalkörper 1 besteht aus zwei Platten 2 und 3, die in gewölbter Form miteinander verleimt sind. Im Querschnitt ist der Schalkörper 1 trogartig gebildet. Um den Schalkörper 1 in eine Sparschalung, die bekanntlich aus im Abstand zueinander verlegten Bohlen 4 besteht, einsetzen zu können, werden zweckmäßig Halteklammern 5 verwendet. Wie F i g. 2 zeigt, bestehen die Halteklammern 5 aus einem Blechwinkel, dessen einer Schenkel zu einer Klammer zurückgebogen ist. Mit dem planen Schenkel werden die Halteklanunern 5 auf die Bohlen 4 der Sparschalung aufgelegt und sodann in den zu einer Klammer gebogenen Schenkel der Schalkörper mit seinem Steg von oben eingeschoben.The shell 1 consists of two panels 2 and 3, which are glued together in a curved shape. In cross section, the shell body 1 is trough-shaped. In order to be able to use the formwork 1 in a formwork which, as is well known, consists of planks 4 laid at a distance from one another, retaining clips 5 are expediently used. Like F i g. 2 shows, the retaining clips 5 consist of a sheet metal angle, one leg of which is bent back into a clip. With the flat leg, the holding clasps 5 are placed on the planks 4 of the economy formwork and then the formwork body with its web is inserted from above into the leg, which is bent into a clamp.
