Abstract

The invention concerns a novel solution to the problem of providing a connection in wood-concrete composite structures. Wood-concrete connecting elements of this type can be used in the construction of new buildings or the renovation of old ones, and in bridge building. The novelty of the connecting element lies in the principle of the transmission of shearing forces between the wood (4) and concrete (5). The shearing forces are transmitted by a larger rod-shaped connecting element (1) via a plate (3) to a number of smaller rod-shaped connecting elements (2).

Description

Das Verbundelement ist der verbindende Teil von Holz- Beton- Verbundquerschnitten, welche-im Bauwesen vor allem bei biegebeanspruchten Trägern und Platten im Neubau und in der Altbausanierung sowie im Brückenbau zur Anwendung kommen. Das Gegenstand der Erfindung entsprechend den Patentansprüchen bildende Verbundelement basiert auf einem neuartigen Prinzip der Übertragung der Schubkräfte in der Fuge zwischen dem auf Biegung bzw. Zug beanspruchten Holzquerschnitt und der auf Druck, beanspruchten Betonplatte, mit welchem eine sehr steife Verbindung der beiden Materialien erreicht wird.The composite element is the connecting part of wood-concrete composite cross-sections, which - in construction, especially for beams subjected to bending stress and slabs in new and old buildings as well as in bridge construction Application come. The object of the invention according to the claims Composite element is based on a new principle the transfer of shear forces in the joint between the on bend or train stressed wood cross-section and the stressed pressure Concrete slab, with which a very rigid connection of the two Materials is achieved.

Für die Herstellung von Holz- Beton- Verbundtragwerken wurden bereits eine Vielzahl von Verbundlösungen entwickelt, welche sich methodisch in Stabförmige Verbindungsmittel, Eingelassene oder eingepresste Spezialbauteile, Verklebung und Formschluss gliedern lassen. Das vorgeschlagene auf dem Dübelprinzip basierende Verbundelement gehört zur Gruppe der Stabförmigen Verbindungsmittel. Der dabei zugrundeliegende Stand der Technik kann am zutreffendsten mit dem Patentdokument CH-A-0683358 angegeben werden. Darnach wird die Verbindung zwischen Holz- und Stahlbetonbauteilen mit Nägeln, Kopfpassbolzen bzw. Passschrauben hergestellt.There have already been one for the production of wood-concrete composite structures A large number of composite solutions have been developed, which are methodically transformed into rod-shaped Lanyards, recessed or pressed-in special components, gluing and form fit. The proposed one based on the dowel principle Composite element belongs to the group of rod-shaped connecting means. The state of the art on which this is based can most appropriately be with the Patent document CH-A-0683358 can be given. After that the connection between wood and reinforced concrete components with nails, head fitting bolts or Fit bolts made.

Ein Verbundelement gemäß dem Oberbegriff des unabhängigen Anspruchs ist aus der Druckschrift EP-A-0 432 484 bereits bekannt, vgl. insbesondere die Figur 2.A composite element according to the preamble of the independent Claim is from the document EP-A-0 432 484 already known, cf. in particular FIG. 2.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein optimiertes Verbundelement für Holz-Beton-Verbundtragwerte zu konzipieren.The object of the present invention is an optimized composite element to be designed for wood-concrete composite load values.

Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Patentanspruches 1 aufgeführten Merkmale gelöst. Dabei werden die Schubkräfte zwischen Beton und Holz von einem grösseren stabförmigen Verbindungsüber eine auf der Holzoberfläche anliegende, das grössere Verbindungsmittel umgebende Scheibe beliebiger Form auf um das grossere Verbindungsmittel herum angeordnete kleinere stabförmige Verbindungsmittel beliebiger Zahl in das Holz übertragen. Dabei wird ein kleinerer Teil der Schubkräfte naturgemäss vom grösseren stabförmigen Verbindungsmittel allein übertragen, welches im übrigen für das statische Gleichgewicht der am Verbundelement angreifenden inneren Kräfte notwendig ist. This object is achieved by the in the characterizing part of Features listed 1 solved. In doing so, the thrust forces between concrete and wood from a larger rod-shaped connection over a larger lanyard that lies on the wooden surface surrounding washer of any shape around the larger connecting means smaller rod-shaped connecting means of any number arranged in transferred the wood. A smaller part of the thrust is natural transferred from the larger rod-shaped connecting means alone, which in the rest for the static balance of those attacking the composite element internal forces is necessary.

Mit den abhängigen Patentansprüchen wird dokumentiert, dass der Erfindungsgegenstand in verschiedenen vorteilhaften Ausführungsformen hergestellt werden kann, welche sich in der Art der stabförmigen Verbindungsmittel unterscheiden.The dependent patent claims document that the subject of the invention can be produced in various advantageous embodiments, which differ in the type of rod-shaped connecting means.

In den Zeichnungen ist die geeignetste Ausführungsform der Erfindung darge-stellt. Sie besteht aus einer achteckigen Scheibe 3, einem Kopfbolzendübel als grösseres stabförmiges Verbindungsmittel 1 und acht Ankernägeln mit Wulst als kleinere stabförmige Verbindungsmittel 2; letzere wegen ihrer Kofpeinspannung in der auch als Platte wirksamen Scheibe 3 eine besonders steife Verbindung ergebend.The most suitable embodiment of the invention is shown in the drawings. It consists of an octagonal disc 3, a headed pin as larger rod-shaped connecting means 1 and eight anchor nails with bulge than smaller rod-shaped connecting means 2; the latter because of their caffeine tension in the disk 3, which also acts as a plate, a particularly rigid connection yielding.

Figur 1 zeigt eine Axonometrie des Verbundelementes mit dem grösseren stabförmigen Verbindungsmittel 1 und der dieses umgebenden Scheibe 3.Figure 1 shows an axonometry of the composite element with the larger rod-shaped Connecting means 1 and the disk 3 surrounding it.

Figur 2 zeigt eine Ansicht des Verbundelementes von Figur 1 mit den eingesteckten kleineren stabförmigen Verbindungsmitteln 2.Figure 2 shows a view of the composite element of Figure 1 with the inserted smaller rod-shaped connecting means 2.

Figur 3 zeigt einen Schnitt durch die Scheibe 3.FIG. 3 shows a section through the pane 3.

Figur 4 zeigt eine Ansicht der Scheibe 3.FIG. 4 shows a view of the pane 3.

Figur 5 zeigt den Querschnitt eines Plattenbalkens mit eingebautem Verbundelement.Figure 5 shows the cross section of a plate beam with built-in composite element.

Figur 6 zeigt den Figur 5 entsprechenden Längsschnitt eines Plattenbalkens.FIG. 6 shows the longitudinal section of a plate beam corresponding to FIG. 5.
