Abstract

The connection device for coupling between a concrete floor (18) and a column (16) has a central diagonal strut (27) with an edge girder (19) bordering this diagonal strut (27), as well as connecting means (20, 24) projecting outwardly and inwardly from the edge girder (19). A central head plate (21) is additionally provided. The connecting means are welded bolts (20, 24). They may, however, also be steel hoops, screw bolts, rolled sections or tubular portions. Compared with the prior art, this connection device exhibits lower material consumption for the same stresses. It provides advantageous force relationships in the region of the support of the floor (18) on the column (16). It therefore requires a minimal amount of material for given force relationships and is thus less damaging to the environment. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Verbindungs­vorrichtung zum Anschliesen einer Betondecke an eine Stütze sowie ein Bauwerk mit mindestens einer Vor­richtung.The present invention relates to a connecting device for connecting a concrete ceiling to a support and a structure with at least one device.

Es ist bekannt, dass beim Abstützen von Betondecken auf Stützen, wenn nicht besondere Massnahmen getrof­fen werden, ein sog. Stanzeffekt auftritt, wobei die Stütze als Stempel auf die Betondecke wirkt und einen sich in der Decke normalerweise erweiternden Teil we­gen übermässiger Spannungen ausstanzt.It is known that when concrete ceilings are supported on supports, unless special measures are taken, a so-called punching effect occurs, the support acting as a stamp on the concrete ceiling and punching out a part that normally widens in the ceiling due to excessive tension.

Es sind seit langem entsprechende Vorkehrungen ge­troffen worden, um Kräftespitzen beim Ueberleiten der Kräfte aus der Betondecke in die Stütze durch ent­sprechende Vorkehrungen so zu führen, dass derartige Stanzerscheinungen ausbleiben.Appropriate measures have long been taken to take force peaks when transferring the forces from the concrete ceiling to the column by taking appropriate measures so that there are no punching phenomena.

In diesem Sinne ist ein Stützenkopf zum Anschluss ei­ner Betonmassivdecke an eine Stahlprofilstütze mit einem vertikalen Durchlass für Versorgerleitungen be­kannt geworden, bei welcher Konstruktion der Kopfteil der Stahlprofilstütze mit vertikalen, flügelartigen Stahlblechen versehen wird. Dabei ist ein Veranke­rungsteil vorgesehen, der aus Reihen von Kopfbolzen­dübeln besteht, die an den flügelartigen Stahlblechen der Stahlprofilstütze angeschweisst sind. Dieser Stützenkopf vermeidet Spitzenbelastungen, was insbe­sondere aufgrund des Verankerungsteils, der aus Kopf­ bolzendübeln besteht, erreicht wird. (DE-OS 29 20 044) Dieser Stützenkopf ist nur für Stahlprofilstüt­zen verwendbar, der offenbarte Grundgedanke ist mit­hin nicht für reine eisenarmierte Betonbauwerke zu verwenden. Auch dienen die verwendeten Kopfbolzendü­bel ausschliesslich zum Auflegen und nicht zum mecha­nischen Verbinden mit Betonbewehrungseisen.In this sense, a column head for connecting a solid concrete ceiling to a steel profile column with a vertical passage for utility lines has become known, in which construction the head part of the steel profile column is provided with vertical, wing-like steel sheets. In this case, an anchoring part is provided, which consists of rows of headed dowels which are welded to the wing-like steel sheets of the steel profile support. This prop head avoids peak loads, which is particularly due to the anchoring part that is made up of head there is bolting, is achieved. (DE-OS 29 20 044) This column head can only be used for steel profile columns, the basic idea disclosed is therefore not to be used for pure iron-reinforced concrete structures. The headed dowels used are only used for laying on and not for mechanical connection with concrete reinforcing bars.

Es ist ferner eine Stahlbetondecke mit wenigstens ei­ner vertikalen Stütze bekannt geworden, bei welcher die Verbindung von Decke und Stütze oder Stützen an der bzw. an jeder Verbindungsstelle durch ein aus Stahlprofil gebildetes, mindestens zweiwinklig zuein­ander stehende Schenkel aufweisendes, horizontal an­geordnetes Element gebildet ist. Die freien Schenkel dieses Elementes sind durch wenigstens ein Stahlglied miteinander verbunden. Zwischen den Schenkeln des ho­rizontalen Elementes und dem zugehörigen Stahlverbin­dungsglied besteht betonfreier Raum zur Durchführung von Leitungen. (CH-PS 430 128)Furthermore, a reinforced concrete ceiling with at least one vertical support has become known, in which the connection of the ceiling and the support or supports at or at each connection point is formed by a horizontally arranged element made of steel profile and having at least two angles to one another. The free legs of this element are connected to one another by at least one steel link. Concrete-free space for the passage of lines exists between the legs of the horizontal element and the associated steel connecting link. (CH-PS 430 128)

Zum Stande der Technik gehört ferner ein metallischer Säulenknauf, welcher als Verbindungselement zwischen einer stützenden Säule, auf welcher er befestigt ist und einer armierten Betonplatte dient, in welcher Platte er eingegossen ist. Dieser Säulenknauf besteht aus mehreren Stäben, welche miteinander verschweisst sind und welche ein Polygon umschreiben, wobei die von diesem Polygon abstehenden Enden der Stäbe frei­tragend sind. Diese Stäbe oder Profile sind mit, ge­gen das Innere des Polygons weisenden, Stiften verse­hen, welche der Verankerung im Beton dienen.The prior art also includes a metallic column knob, which serves as a connecting element between a supporting column, on which it is fastened, and an armored concrete slab, in which slab it is cast. This column knob consists of several rods, which are welded together and which circumscribe a polygon, the ends of the rods protruding from this polygon being self-supporting. These bars or profiles are provided with pins pointing towards the inside of the polygon, which are used for anchoring in the concrete.

Auch diese Konstruktion vermag den heutigen Anforde­rungen nicht mehr gerecht zu werden. (CH-A- 596 399)This construction is also no longer able to meet today's requirements. (CH-A-596 399)

Es gehört ferner ein Bauwerk zum Stande der Technik, bei welchem ein Pilz eine mittlere Oeffnung zum Ein­schieben einer Stütze von oben her besitzt. Dabei wird die in der mittleren Oeffnung befindliche Platte nachträglich mit dem Pilz verbunden, z.B. ver­schweisst.A building is also part of the prior art, in which a mushroom has a central opening for inserting a support from above. The plate in the middle opening is subsequently connected to the mushroom, e.g. welded.

Diese Veröffentlichung stellt den Stand der Technik dar und zeigt den Nachteil bisheriger Konstruktionen, indem nämlich die Verbindung zwischen Pilz und wei­teren Armierungselementen z.T. durch Schweissung er­folgt. Dieses Verfahren ist aufwendig und daher kostspielig. Es verlangt besondere Massnahmen am Ort der Erstellung der Baute. (EP-A- 128 494)This publication represents the state of the art and shows the disadvantage of previous designs, namely that the connection between the mushroom and other reinforcing elements partly. done by welding. This process is complex and therefore expensive. It requires special measures at the place where the building is constructed. (EP-A-128 494)

Die vorliegende Erfindung bezweckt die Schaffung ei­ner Verbindungsvorrichtung, welche gegenüber dem Stand der Technik einen geringen Stahlverbrauch auf­weist, vorteilhafte Kräfteverhältnisse im Bereich der Abstützung der Decke auf der Stütze schafft und um­weltfreundlich ist.The present invention aims to provide a connecting device which, compared to the prior art, has a low steel consumption, creates advantageous force relationships in the area of supporting the ceiling on the support and is environmentally friendly.

Eine derartige Verbindungsvorrichtung ist gekenn­zeichnet durch den Wortlaut eines der Ansprüche.Such a connecting device is characterized by the wording of one of the claims.

Die Erfindung wird anschliessend beispielsweise an­hand einer Zeichnung erläutert.The invention is subsequently explained, for example, using a drawing.

In Fig. 1 ist eine Stütze 1 ersichtlich, mit einer Betondecke 2, bei welcher Konstruktion keine beson­deren Massnahmen zur Kräfteüberleitung von der Be­tondecke 2 in die Stütze 1 vorgesehen sind, also insbesondere auch kein Stützkopf. Es tritt dann der bekannte Ausbruch 4 auf, welcher die Decke zum Ein­sturz bringen kann.1 shows a support 1 with a concrete ceiling 2, in which construction no special measures for transferring forces from the concrete ceiling 2 into the support 1 are provided, that is to say in particular also no support head. The well-known eruption 4 then occurs, which can cause the ceiling to collapse.

Die in den Fig. 2 und 3 dargestellte erfindungsge­mässe Konstruktion zeigt eine Stütze 16 mit einem Rahmen, der als Randträger 19 dient und aus Flach­stahl, glasfaserarmiertem Kunststoff o. dgl. herge­stellt ist. Ferner sind äussere und innere Verbund­mittel 20 und 24 nach aussen und innen vom Randträ­ger 19 igelartig vorstehend angeordnet.The construction according to the invention shown in FIGS. 2 and 3 shows a support 16 with a frame, which serves as an edge support 19 and is made of flat steel, glass fiber reinforced plastic or the like. Furthermore, outer and inner composite means 20 and 24 are arranged in a hedgehog-like manner projecting outwards and inwards from the edge carrier 19.

Von den nach innen abstehenden Verbundmitteln 24 wird die Kraft über eine Betondruckstrebe 27 der Stütze 16 übergeben.The force is transferred from the inwardly projecting composite means 24 to the support 16 via a concrete pressure strut 27.

Allfällige Momente sowie nicht von Betondruckstreben übernommene Kräfte können mittels eines Kreuzes 17 aus Trägern übergeben werden. Eine Druckplatte 21, zentrisch angeordnet, übergibt diese Kräfte an die Stütze 16.Any moments as well as forces not taken over by concrete pressure struts can be transferred from beams using a cross 17. A pressure plate 21, arranged centrally, transfers these forces to the support 16.

In den Fig. 4 und 4a wird die erfindungsgemässe Kon­ struktion gezeigt mit einer Stütze 16 sowie einem Rahmen 28 aus einem Z-Profil als Randträger. Auch hier können ein Kreuz 17 und eine Druckplatte 21 vorgesehen werden.4 and 4a, the con structure shown with a support 16 and a frame 28 made of a Z-profile as an edge beam. A cross 17 and a pressure plate 21 can also be provided here.

Die Fig. 5 bis 12 zeigen verschiedene Variationen und Anwendungen erfindungsgemässer Vorrichtungen beim Stützen von Betondecken. Dabei sind die Formen quadratisch, rechteckig, vieleckig, kreisförmig, oval oder es sind andere Formen vorgesehen.5 to 12 show different variations and applications of devices according to the invention when supporting concrete ceilings. The shapes are square, rectangular, polygonal, circular, oval or other shapes are provided.

Fig. 13 zeigt Ausschnitte u.a. aus den Fig. 2 und 4, in verschiedenen Ausführungsvarianten. Als Hauptge­bilde können Randträger 19 und 28 mit oder ohne im Kreuz angeordneten oder in die Diagonalen verlegten Ergänzungsträgern 17 verwendet werden. Als Formen können für diese Flach- bzw. Breitflachbleche, Dop­pel-T- oder T-Walzprofile oder andere Arten zusam­mengesetzter Profile und Verbundkonstruktionen aus entsprechenden Materialien Anwendung finden.Fig. 13 shows sections, among others. 2 and 4, in different versions. Edge supports 19 and 28 with or without additional supports 17 arranged in a cross or laid in the diagonals can be used as main structures. Shapes can be used for these flat or wide flat sheets, double-T or T-rolled profiles or other types of composite profiles and composite structures made of appropriate materials.

Die Randträger 19, 28, hier als Flacheisen oder Z-­Profile dargestellt, können aber auch als L-Profile, als Kastenprofile oder in irgendeiner Zusammenset­zung bzw. als Verbundkonstruktionen ausgeführt wer­den.The edge beams 19, 28, shown here as flat bars or Z-profiles, can also be designed as L-profiles, as box profiles or in any composition or as composite structures.

Fig. 14 zeigt einen Ausschnitt aus einer Armierungs­führung für eine statisch einwandfreie Verankerung. Auf dem obern Ende der Stütze 16 ist in einer Beton­decke 18 der Randträger 19 mit den Verbundmitteln 20 einbetoniert, wie dies analog z.B. anhand der Fig. 2 und 3 erläutert ist. Die Decke 18 ist mittels Armie­rungsstählen 30 armiert. Aus der Darstellung ist er­sichtlich, wie hier der U-förmig gebogene Armie­rungsstahl über die Verbundmittel 20 mit dem Rand­träger 19 verbunden ist.14 shows a section of a reinforcement guide for a structurally perfect anchoring. On the upper end of the support 16, the edge girder 19 with the composite means 20 is concreted in a concrete ceiling 18, as is analogous, for example, with reference to FIG. 2 and 3 is explained. The ceiling 18 is reinforced by means of reinforcing steels 30. From the illustration it can be seen how the U-shaped reinforcing steel is connected to the edge support 19 via the composite means 20.

Diese Ausführungsart erlaubt eine einwandfreie, übersichtliche Kräfte-Uebertragung von der Decke 18 in die Stütze 16. Dank dieser neuen Konstruktion ge­hören die leidigen Probleme mit der unteren Armie­rung, hier in Form des Stahles 30, bezüglich Veran­kerung, Schnittlängen und Schweissverbindungen end­gültig der Vergangenheit an; denn die, z.B. als Bol­zen 20 ausgebildeten Verbundmittel werden mit dem Armierungsnetz nicht verschweisst, wobei der Boden der U-förmig gebogenen Stähle 30 vorzugsweise den Rahmen berührt.This type of construction allows a flawless, clear transfer of forces from the ceiling 18 to the support 16. Thanks to this new construction, the troublesome problems with the lower reinforcement, here in the form of steel 30, are finally a thing of the past with regard to anchoring, cutting lengths and welded connections; because that, e.g. Composite means designed as bolts 20 are not welded to the reinforcement network, the bottom of the U-shaped steels 30 preferably touching the frame.

Als Verbundmittel dienen Schweissbolzen, Bügel aus Stahl oder schrauben- bzw. spiralförmig gewundene Stäbe, Walz-Profilabschnitte oder Rohrabschnitte be­liebiger Formen und Materialien, insbesondere auch Z-Profilrahmen.Welding studs, steel brackets or helically or spirally wound rods, rolled profile sections or pipe sections of any shape and material, in particular also Z-profile frames, serve as the connecting means.

Für die Kopfplatten wird normalerweise Flach- bzw. Breitflachblech verwendet. Deren Form kann quadra­tisch, rechteckig, kreisförmig oder sternförmig sein. Es ist aber auch möglich, ohne diese Kopfplat­ten zu konstruieren und entsprechend die Kreuze zu dimensionieren.Flat or wide flat sheet metal is normally used for the head plates. Their shape can be square, rectangular, circular or star-shaped. But it is also possible without constructing these head plates and dimensioning the crosses accordingly.

Die erfindungsgemässen Vorrichtungen erlauben hori­ zontale und vertikale Aussparungen in der Decke. Sie eignen sich insbesondere für mittlere bis grosse La­sten, sind aber für diese material- und damit ko­stensparend. Sie bilden komplette Einheiten mit re­lativ kleinem Verlegegewicht und sind in jeder Be­ziehung kostengünstig. Sie entsprechen im übrigen der Norm SIA 160, 162.The devices according to the invention allow hori zonal and vertical recesses in the ceiling. They are particularly suitable for medium to large loads, but are material and therefore cost-saving for them. They form complete units with a relatively small installation weight and are inexpensive in every respect. They also comply with the SIA 160, 162 standard.

Bei diesen, auf einer gemeinsamen Grundidee fussen­den Konstruktionen werden die äusseren Kräfte über äussere Verbundmittel auf ein rahmenartiges Gebilde übertragen und von dort auf innere Verbundmittel. Von hier gelangen diese Kräfte als Druckkräfte auf eine Druckstrebe, welche diese Kräfte auf die Stütze weiterleitet.In these constructions, which are based on a common basic idea, the external forces are transferred to a frame-like structure via external composite means and from there to internal composite means. From here, these forces arrive as pressure forces on a pressure strut, which transmits these forces to the support.

Dabei müssen die inneren Verbundmittel 24 näher bei der oberen, normal zur Stütze liegenden Abschluss­ebene der Decke liegen als die äusseren Verbundmit­tel 20, damit die in der Druckstrebe eingeführten Druckkräfte mit dieser Abschlussebene einen Mindest-­Neigungswinkel ψ bilden, der gemäss SIA-Normen grös­ser als 25° sein soll. Würde dieser Winkel zu klein, so sind mehrere Rahmen mit Verbundmitteln vorzuse­hen, um die Zuführung der Kräfte unter einem Winkel > 25° zur Stütze sicherzustellen.The inner connection means 24 must be closer to the upper end plane of the ceiling, which is normal to the support, than the outer connection means 20, so that the pressure forces introduced into the pressure strut form a minimum inclination angle ψ with this end plane, which is greater than 25 according to SIA standards ° should be. If this angle becomes too small, several frames with composite materials must be provided to ensure that the forces are applied at an angle> 25 ° to the support.

Die in Einzelheiten erläuterte neue Konstruktion bietet ein grösstmögliches Mass an Sicherheit und verbessert die Biegefestigkeit im Auflagebereich. Zudem ermöglicht sie eine einwandfreie Bewehrungs­fuhrung und dadurch eine optimale Krafteinleitung.The new construction explained in detail offers the greatest possible degree of safety and improves the bending strength in the contact area. In addition, it enables perfect reinforcement management and thus optimal force transmission.

Sie ist damit insbesondere hervorragend zur Aufnahme von hohen Durchstanzlasten geeignet.It is therefore particularly well suited for absorbing high punching loads.

Dabei ist mithin vorteilhafterweise

  • a) keine Schubarmierung notwendig, da τ eff. < als τ zul.
  • b) alles vollständig einbetoniert. Es gibt keine vorstehenden Teile.
  • c) eine einfache Bewehrungsführung sicherge­stellt, da alle Verbundmittel, z.B. die Bolzen 20, in einer Ebene liegen.
It is therefore advantageous
  • a) no shear reinforcement necessary, since τ eff. <as τ allow.
  • b) everything completely concreted. There are no protruding parts.
  • c) simple reinforcement routing ensured, since all the composite means, for example the bolts 20, lie in one plane.

Diese Verbindungselemente werden als "Igel" be­zeichnet, insbesondere als Riss-Igel.These connecting elements are referred to as "hedgehogs", in particular as torn hedgehogs.

Es kann, insbesondere bei Aussparungen innerhalb der Randträger, nötig werden, diesen durch z.B. kreuzartige mittige Träger zu verstärken.It may be necessary, especially in the case of recesses within the edge girders, e.g. reinforce cruciform central straps.

Alle in der Beschreibung und/oder den Figuren dar­gestellten Einzelteile und Einzelmerkmale sowie de­ren Permutationen, Kombinationen und Variationen sind erfinderisch, und zwar für n Einzelteile und Einzelmerkmale mit den Werten n = 1 bis n →∞.All of the individual parts and individual features shown in the description and / or the figures and their permutations, combinations and variations are inventive, namely for n individual parts and individual features with the values n = 1 to n → ∞.
