Definitions

  • the present invention relates to a connector for two workpieces, with two fittings, which can be fastened with one side on each of the workpieces and with their other sides to each other for conditioning, and two clamping jaws which grip the fittings at diametral ends and by means of at least one threaded rod against each other are tensioned, which runs approximately parallel to said other sides.
  • Such wood connectors are sold, for example, by the company Knapp GmbH, Euratsfeld, Austria, under the brand Megant ° and are particularly suitable for building heavy-duty connections in timber engineering, for example, for connecting main, secondary and / or cross members, cross trains, trusses , Supports or the like.
  • the fittings and clamping jaws are usually made of metal, e.g. high-strength aluminum, and the wooden workpieces to be joined, such as glued laminated timber (BSH), laminated beams, etc.
  • One of the workpieces may also be a concrete beam, a wall or a floor, to which a carrier is to be connected by means of the connector.
  • the invention has the aim of further improving such a connector in terms of its load-bearing capacity.
  • a connector of the aforementioned type which according to the invention is characterized in that said one side of at least one fitting, preferably both fittings, is provided with a finger joint profile.
  • a high-strength finger joint connection between fitting and workpiece can thus be created, which achieves an intimate, positive and non-positive connection of the connector to the workpiece.
  • the fitting can optionally also be glued to the workpiece to achieve an additional bond between the two parts.
  • the connector according to the invention is also particularly suitable for workpieces made of fast-growing woods, which have a lower density and thus lower strength and thus provide less support for screwing the fitting.
  • the Zeilverzinkung can be here on an increase in the number of screws, which would otherwise be required to compensate for the lower density, be dispensed with.
  • the number of screws required to fasten the fittings can be reduced, thus saving weight and costs. It is also possible to reduce costly oblique screw connections or to replace them with straightforward straight fittings which are to be produced more easily.
  • the finger joints of the finger joint profile run approximately normal to the threaded rod, so that they can absorb or support tensile and compressive forces in the direction of the threaded rod (s) well.
  • flank angles of the finger joints of the finger joint profile are preferably self-locking in order to ensure a good absorption of force.
  • a particularly advantageous embodiment of the invention is characterized in that the finger jointing profile is formed in an adapter plate, which is inserted into said one side of a fitting or mounted thereon.
  • the connector of the invention can thereby be modularly constructed, stored and used. Different adapter plates with different finger joint profiles can be used with one and ben fitting basic body can be combined to allow adaptation to different workpiece materials, such as wood qualities. Thus, adapter plates with different finger joint profiles in terms of tine length, zinc pitch, tine play, flank angle, etc., depending on the workpiece and application can be used.
  • the adapter plate can be plugged together with the rest of fitting, latched, locked, glued and / or screwed.
  • the tips of the wedge tines can protrude in a plane from the fitting, which allows a simple, straight milling of the finger joint in the workpiece to be connected.
  • the tips of the finger joints can project from the fitting in the manner of a cylinder segment, whereby, for example, side milling cutters can be used to produce the complementary finger joint in the workpiece to be connected.
