- Such an additive blanket has a structure in which steel profile panels and a reinforced concrete ribbed ceiling cooperate in such a way that an additive bearing effect is made possible.
- the system is designed in such a way that a global deformation compatibility is established in which the deflection of the profiled sheets and the reinforced concrete ribbed ceiling is the same for loads above the dead load.
- support elements are placed on support elements in a first step and connected by means of setting bolts with the support element.
- the support elements are cantilevered over the steel beams protruding elements that are welded to the steel beams, for example, and on which the steel trapezoidal sheets with the bottom of their inner corners, left and right of the troughs, rest. Also in the DE 42 15 686 C1 described.
- a reinforced concrete ribbed ceiling is produced, which is connected via connecting elements with the support structure, wherein the underside
- the reinforced concrete ribbed ceiling is formed by the shape of profile sheets or steel trapezoidal sheets and the top is a flat surface.
- One of the advantages of this design is the relatively low weight and low height.
- the composite girder is a steel girder, welded to the headbolt, which, together with the concrete layer of the reinforced concrete ribbed girder, forms a composite structure.
- the steel beam is pegged with a head bolt.
- a disadvantage of this construction is the different ductility of head bolt dowels and support elements or steel catches.
- the steel catches are to be made as rectangular solid material. Since a suitably designed Vollstahlstahlknagge has a much lower ductility, so the property of plastically deforming under load before it fails, as the head bolt must be an elastic material, e.g. a foam layer, between steel knob and concrete, placed in the area of the composite support. This has an increased construction effort.
- the shows US 31 08 662 A a roof or ceiling construction of steel box sections, which are arranged on a substructure, wherein the box sections additionally mounted with their upper flanges mounted transversely on the support beams of the substructure, and rest from support to support continuous rods.

- the composite construction according to the invention for a roof or ceiling slab comprises a supporting structure made of steel beams, profiled sheets which are coupled to the supporting structure via a carrier element, and a steel concrete layer which is designed as a reinforced concrete ribbed slab and which is connected to the supporting structure via connecting elements.
- the composite structure is constructed such that forces F acting on the roof or ceiling slab, decoupled from the profile sheets and the reinforced concrete ribbed ceiling are transferred from one another to the support structure.
- the proposed composite structure is characterized in that the support elements and the connecting elements are fastened to the steel girders of the support structure and cast into the concrete of the concrete layer, wherein the support elements are designed as thin-walled profile elements, wherein the ductility of the support elements and the connecting elements is substantially identical and the vertical contact surfaces of the support elements are in direct contact with the concrete.
- the use of a thin-walled profile element creates a softness in the direction of the carrier axis which renders it unnecessary to cushion the profile element.
- the carrier elements in such a way that they can not absorb any appreciable normal pressure forces, so that in the design of the composite construction, in particular in the composite carrier area, the carrier elements can be disregarded.
- This has the advantage that the essential normal pressure forces are transmitted via the connecting elements, which have a corresponding ductility in order to ensure the required load distribution.
- the profile sheets can be steel trapezoidal sheets, the peaks of the steel trapezoidal profiles with the underside of their inner corners, on cantilevered transversely over the steel beams protruding support elements rest.
- the carrier element may be a rod-shaped thin-walled profile element.
- the carrier element may preferably be designed as a tube, square tube, T-profile, U-profile or L-profile.

- the support elements 5 and the connecting elements 6 are attached. Preferably, these are welded, in particular for the support member 5, other mounting options are conceivable.
- the connecting element 7 is a headed bolt, as used for such ceilings to make a bond with concrete.
- the head bolts must be designed so that they absorb the total thrust in the transverse direction of the span 12 of the ceiling.
- the steel trapezoidal profiles 4 lie with their underside between the inner corners 8 on the support elements 5, which project cantilevered across the substructure, on.
- the steel trapezoidal sheet 4 may have different shapes, which shape determines the shape of the reinforced concrete ribbed slab on the underside.
- the attachment of the steel trapezoidal sheets 4 to the support elements 5 is preferably carried out by means of self-tapping screws which are screwed without a pre-drilling directly from above through the steel trapezoidal sheet 4 in the upper flange 10 of the square hollow section 5.
- the steel concrete layer of reinforced concrete ribbed ceiling is produced, whereby only the required reinforcing bars 11 are inserted according to the requirements and then a concrete layer is applied.
- FIG. 2 the static model of an additive cover is shown.
- the upper illustration shows the ceiling in the unloaded state, in which only the weight of the ceiling layers, so the profile sheets 4 and the reinforced concrete ribbed ceiling 6 acts.

It is shown that the head bolt dowels 7 and the tubes 5, which form the carrier elements, are stressed in the transverse direction as a result of the thrust connection. Due to the high flexibility of the relatively thin wall is a bending of the square tube 5 in the elastic region. It must therefore be provided no additional components for decoupling.

- FIG. 4 different embodiments of the carrier element 5 and exemplified the screw connection are shown.
- the known compound of profile sheet 3 and support member 5 by means of setting bolts has a lower load capacity than the proposed screw connection with self-tapping screws 9 in the upper flange 10, in particular a square tube accordingly 4b ,

Description
Die Erfindung betrifft eine Verbundkonstruktion für eine Dach- oder Deckenplatte wie sie beispielsweise bei der Erstellung von Industriebauten oder Parkdecks Verwendung findet.The invention relates to a composite construction for a roof or ceiling plate as used for example in the construction of industrial buildings or parking decks use.
Eine derartige Verbundkonstruktion besteht aus einer Tragstruktur aus Stahlträgern, die ein Grundgerüst bilden, und einer Dach- oder Deckenplatte die an dieses Gerüst angekoppelt wird. Die Länge der vertikalen Träger des Grundgerüstes bestimmt den Abstand der Deckenplatten zueinander.Such a composite construction consists of a support structure of steel beams forming a skeleton, and a roof or ceiling slab which is coupled to this framework. The length of the vertical support of the skeleton determines the distance of the ceiling panels to each other.
Ein dem Fachmann geläufiger Aufbau einer Additivdecke ist aus der allgemeinen bauaufsichtlichen Zulassung Nr. Z26.1-44 zu entnehmen.A construction of an additive blanket familiar to the person skilled in the art can be taken from the general building inspectorate approval no. Z26.1-44.
Eine derartige Additivdecke hat einen Aufbau bei dem Stahlprofiltafeln und eine Rippendecke aus Stahlbeton derart zusammenwirken, dass eine additive Tragwirkung ermöglicht wird. Das System ist dabei derart ausgelegt, dass sich eine globale Verformungskompatibilität einstellt, bei der die Durchbiegung der Profilbleche und der Stahlbetonrippendecke bei Lasten oberhalb der Eigenlast gleich ist.Such an additive blanket has a structure in which steel profile panels and a reinforced concrete ribbed ceiling cooperate in such a way that an additive bearing effect is made possible. The system is designed in such a way that a global deformation compatibility is established in which the deflection of the profiled sheets and the reinforced concrete ribbed ceiling is the same for loads above the dead load.
Zur Erstellung einer derartigen Verbundkonstruktion werden in einem ersten Schritt Profilbleche auf Trägerelemente aufgelegt und mittels Setzbolzen mit dem Trägerelement verbunden. Die Trägerelemente sind quer über die Stahlträger kragarmartig hinausragende Elemente, die an den Stahlträgern beispielsweise angeschweißt sind, und auf denen die Stahltrapezbleche mit der Unterseite ihrer inneren Ecken, links und rechts neben den Wellentälern, aufliegen. Auch in der
In einem zweiten Schritt wird eine Stahlbetonrippendecke hergestellt, die über Verbindungselemente mit der Tragstruktur verbunden ist, wobei die Unterseite der Stahlbetonrippendecke durch die Form der Profilbleche oder Stahltrapezbleche gebildet wird und die Oberseite eine ebene Fläche ist.In a second step, a reinforced concrete ribbed ceiling is produced, which is connected via connecting elements with the support structure, wherein the underside The reinforced concrete ribbed ceiling is formed by the shape of profile sheets or steel trapezoidal sheets and the top is a flat surface.
Einer der Vorteile dieser Bauweise sind das relativ geringe Gewicht und die geringe Bauhöhe.One of the advantages of this design is the relatively low weight and low height.
Ein wesentliches Merkmal und ein wesentliches Problem bei einer derartigen Konstruktion sind die Auslegung und der Aufbau des Verbundträgers. Der Verbundträger ist ein Stahlträger, an den Kopfbolzen angeschweißt sind und der zusammen mit der Betonschicht der Stahlbetonrippendecke eine Verbundkonstruktion bildet. In Fachkreisen auch beschrieben mit, der Stahlträger wird mit Kopfbolzen verdübelt.An essential feature and a major problem with such a design are the design and construction of the composite carrier. The composite girder is a steel girder, welded to the headbolt, which, together with the concrete layer of the reinforced concrete ribbed girder, forms a composite structure. In professional circles also described with, the steel beam is pegged with a head bolt.
Ein Nachteil dieser Konstruktion ist die unterschiedliche Duktilität von Kopfbolzendübeln und Trägerelementen bzw. Stahlknaggen. Entsprechend der Zulassung sind die Stahlknaggen als Rechteckvollmaterial auszuführen. Da eine entsprechend ausgeführte Vollmaterialstahlknagge eine sehr viel geringere Duktilität aufweist, also die Eigenschaft sich unter Belastung plastisch zu verformen, bevor sie versagt, als der Kopfbolzen muss eine elastisches Material, z.B. eine Schaumstoffschicht, zwischen Stahlknagge und Beton, im Bereich des Verbundträgers, platziert werden. Dies hat einen erhöhten baubetrieblichen Aufwand zur Folge.A disadvantage of this construction is the different ductility of head bolt dowels and support elements or steel catches. According to the approval, the steel catches are to be made as rectangular solid material. Since a suitably designed Vollstahlstahlknagge has a much lower ductility, so the property of plastically deforming under load before it fails, as the head bolt must be an elastic material, e.g. a foam layer, between steel knob and concrete, placed in the area of the composite support. This has an increased construction effort.
