Definitions

  • the invention relates to a method for connecting wooden parts, in particular for attaching a first wooden beam z.
  • two beams are screwed together by means of a spindle passing through both beams, and for this purpose a hole is preferably made in each beam with a superimposed countersunk hole at the beginning, both holes being aligned with one another in the connecting position of the beams.
  • the two beams are firmly pulled against each other and clamped together using nuts that are screwed onto both spindle ends and tightened. Therefore, high frictional forces arise at the contact surfaces, which counteract a displacement of the two beams in the connection plane.
  • a ring is introduced into the contact surfaces of the beams in the connecting plane, which concentrically surrounds the spindle at a distance from it and supports the resistance of the connection against shear forces.
  • this method can only be used for connecting beams in which the spindle completely penetrates the beams, so that nuts can be screwed onto the spindle ends on both sides to clamp the beams.
  • the method is therefore only used where there are intersecting beams or those with their ends against each other beams to be fastened are to be connected.
  • the holes extend transversely to the grain of the beams.
  • a bore is made in the longitudinal and fiber direction through the end face of the first beam, a threaded spindle made of metal is inserted into the bore except for an end section projecting from the end face and into the bore attached in particular is glued into this, a ring surrounding the spindle is inserted through the end face of the first beam into the end of the brain, in the second beam in alignment with the bore in the first beam position a continuous bore for receiving the end portion of the spindle the two bars in the connection position are arranged one on top of the other, the end section of the spindle extending through the bore in the second beam and the two beams being fastened to one another by screwing and tightening a nut on the end section of the spindle.
  • connection process can be carried out with very simple means, and it permits extensive prefabrication in the production plant or in the workshop with subsequent assembly on the construction site.
  • Fastening elements inserted in a wooden part in the direction of the fibers usually do not allow tensile stress. Due to a complicated spatial state of tension, so-called split tensile forces arise when individual tensile forces are introduced into the wooden part, in particular in a glulam body. Due to the anisotropy of the material wood, these splitting tensile forces result in impermissibly high transverse tensile stresses, which can lead to a transverse tensile fracture, especially in the end grain section. These transverse tensile stresses are additionally superimposed by transverse tensile stresses from swelling and vibratory movements.
  • the essence of the method according to the invention is that a threaded spindle or threaded rod made of metal is glued into a fiber hole in the brain end of a wooden body to introduce a single load and with the introduction of a ring surrounding the spindle a transverse reinforcement in the area of the brain end of the wooden body referred to above as the first beam is reached.
  • the ring prevents the wooden body from splitting in the area of the brain end near the face or connecting surface, where the splitting tensile forces have their maximum. If the ring also engages in the contact surface of the second beam, it additionally brings about a substantial increase in the shear strength of the connection in a similar manner to the known connection mentioned at the outset, which, however, is based on the two wooden parts being pressed together between the ends of a spindle. Experiments have already shown that a significant increase in the load capacities can be achieved with the connection method according to the invention.
  • the method according to the invention can also be applied to the known connecting method mentioned at the outset, in which the wooden parts are screwed together or onto one another between the spindle ends and are pressed, if these are beams with a crossing fiber direction and the first Beam through which the spindle extends in the direction of the grain, is also suitable for a continuous spindle in length. Because even in this case, pressing the brain end of the first beam against the contact surface of the second beam results in splitting tensile forces, which are counteracted in the form of a ring with the transverse tensile reinforcement according to the invention can be, if necessary, on both brain ends of the first bar.
  • the bore in the first beam in which the spindle is glued in is preferably carried out as a blind bore, which is consequently independent of the respective beam length.
  • the spindle is preferably glued into the bore using epoxy resin. It is essential that the glue creates an absolutely firm connection with the bore wall and a positive connection with the thread of the spindle. In this way, tensile forces introduced via the spindle are evenly transmitted to the layers of the wooden part adjacent to the bore.
  • the ring should preferably be arranged concentrically to the spindle in order to form a uniformly effective reinforcement.
  • the diameter of the ring is to be dimensioned such that the wood core enclosed by the ring covers the area relevant for the strength of the connection and the splitting tensile forces acting beyond the ring cannot destroy the wood part under load.
  • the ring is inserted into an annular groove in the end face of the first beam and glued in with epoxy resin. In this way, a positive connection between the ring and the surrounding layers of wood is brought about, so that a effective reinforcement is achieved.
  • the ring is introduced with one half in the annular groove of the first beam and with the other half in an annular groove which is milled into the contact surface of the second beam concentrically with the bore. This significantly increases the shear strength of the connection. Prefabrication is also easily possible for this.
  • the ring is preferably made of metal with a cross-sectional profile in the form of a rhombus. As a result, the ring can be easily inserted in any case, also driven in if necessary, and it has the strongest cross section in the connecting plane of the two wooden parts.
  • the other half of the ring in the ring groove of the second beam can also be glued there in a form-fitting manner by means of epoxy resin in order to avoid the highest possible resistance to any displacement in the event of shear stresses.
  • the free end of the spindle section is expediently arranged in the second bar by means of a counterbore. In this way, an invisible connection consisting exclusively of internal connecting elements is achieved if the counterbore is closed after the connection has been made.
  • the invention also relates to a connection of wooden parts which can be produced by the above-mentioned and described method, specifically with the further training options shown above.
  • a central bore 5 is made as a blind bore through the end face 7 of the beam 1 in the end of the brain.
  • a steel and threaded spindle 6 is inserted and glued with epoxy resin 7 in the manner shown, so that an end portion 8 of the spindle 6 protrudes well beyond the end face 3.
  • annular groove 9 is milled in a coaxial position at a significant distance from the bore 5 in the end face 3.
  • an aluminum ring 10 with an approximately rhombic cross section is glued in such a way by means of epoxy resin 11 that one half of the ring is embedded and fastened in the annular groove 9 in a form-fitting manner, while the other half protrudes beyond the end face 3.
  • a continuous bore 12 is guided through the beam 2 and is suitable for receiving the end section 12 of the spindle 6.
  • the bore 12 On the side of the bar 2 facing away from the contact surface 4, the bore 12 overlaid by a counterbore 13, as shown.
  • an annular groove 14 is milled out concentrically to the bore 12, which corresponds to the aforementioned annular groove 9.
  • the annular groove 14 is provided with an epoxy resin filling 15 and the beam 2 is placed with its contact surface 4 on the end face 3 of the beam 1 so that the end portion 8 of the spindle 6 passes through the bore 12 and from which End face 3 protruding half of the ring 10 penetrates into the ring groove 14 filled with epoxy resin.
  • a pressure ring 16 and a locking ring 17 are placed on the free end of the spindle 6, and a nut 18 is screwed on and tightened until a tension sufficient for the desired connection is reached.
  • the epoxy resin filling 15 hardens, and the desired tensile, shear and pressure-resistant connection of the beams 1, 2 is achieved.
  • the two beams 1, 2 connected to one another have mutually crossing fiber directions and the bore receiving the spindle runs in the fiber direction of the first beam 1. Nevertheless, the spindle can withstand high tensile loads without the split tensile forces leading to a transverse tensile break.
