Definitions

  • the invention relates to a rigid corner connection between a support and an angled wooden beam of the type specified in the preamble of claim 1.
  • the known corner connection is essentially only suitable for connecting wooden beams of approximately the same cross-sectional height. It cannot be used, for example, if a composite beam of large cross-sectional height composed of several individual beams is to be connected to a steel or reinforced concrete column, for example.
  • the invention has for its object to provide a rigid corner connection of the type mentioned, which is particularly suitable for mixed wood-steel or wood-reinforced concrete construction, which can be manufactured very easily and using prefabricated standard elements and a defined, dimensional tolerances the wooden beams used ensure independent high bending stiffness.
  • the invention also relates, according to claim 12, to a wooden beam suitable for such a corner connection.
  • Fig. 1 and rigid corner connection for Building frame structures consist of a vertical support 1, which is formed by a steel girder, for example with an I-profile, and a wooden beam 3 running at an obtuse angle, which is composed of three individual beams 3a, 3b, 3c arranged one above the other as a composite construction.
  • the bars 3a, 3b, 3c are held together on their side surfaces by nail plates 5 bridging the contact joints, these nail plates in particular also absorbing the shear forces acting along the contact joints.
  • a tab 7 made of steel is inserted between the upper and middle beams 3a, 3b (cf. FIG. 2), which projects beyond the end faces of the two lower beams 3b, 3c and on which the suitable angle bevelled upper end of the support 1 and screwed or welded to it.
  • the end surfaces of the two lower beams 3b, 3c which are also cut off at a suitable angle, bear against the side surface of the support 1.
  • the end of the upper beam 3a extends above and beyond the tab 7 so that it extends over the support 1, e.g. survives to form a roof overhang.
  • Nail plates as used to connect the beams 3a, 3b, 3c used have been known for a long time and are described, for example, in "Bauhandmaschine", August 1984.
  • the tab 7 extends in the contact joint between the beams 3a, 3b in a cutout, which is provided in the beam 3b and / or in the beam 3a, over a considerable distance from the support 7, whereby the length of the tab 7 can be selected in accordance with the loads to be absorbed.
  • Each pin 9 is surrounded by an annular press-in plug 11 provided with claws, the claws of which are pressed into the wood of the beam 3b.
  • Dowel pin 9 and press-in dowel 11 can, as shown in dashed lines, also be provided on the top of the plate 7 for cooperation with the upper beam 3a, or on both sides of the tab 7 for cooperation with both beams 3a, 3b.
  • FIG. 3 shows, in perspective, dowel pins 9 arranged on the upper side of the tab 7, which engage in corresponding bores 13 in the upper beam 3a.
  • the nail plates 5 holding the bars together with nail claws 5a driven into the wood are also indicated in FIG. 3.
  • each dowel pin 9 can be inserted into a hole in the tab 7 and welded to the rear side thereof.
  • the press-in dowel 11 is a loose, annular sheet-metal stamped part with angled claws or prongs 11a and preferably a flanged edge 11b surrounding the inner opening for better support on the dowel pin 9, onto which the press-in dowel 11 is loosely attached.
  • the invention achieves the advantage that the rigid corner connection of the component with prefabricated standard parts, namely the dowel bracket 7, the press-in dowels 11 and the nail plates 5 can be produced, which are not separately manufactured in each case to adapt to different dimensions of the beams and kept in stock Need to become.
  • a very high load-bearing capacity of the rigid corner connection is achieved, since when the wooden beam 3 is loaded, the compressive forces acting underneath the neutral fiber are direct are introduced into the side surface of the support 1 via the end faces of the lower beams 3b, 3c, while the tensile forces acting above the neutral phase are introduced via the press-in dowels 11 and the dowel pins 9 via the dowel bracket 7 and transmitted from there via the welded connection to the support 1 will.
  • the press-in plugs 11 cause the forces to be distributed over a large area into the beams 3a and / or 3b.
  • the corner connection according to the invention is also distinguished by a pleasing appearance, with great freedom in the architectural design, for example in the dimensioning of the protrusion of the beam 3a over the support 1, and the force-absorbing elements 9 and 11 invisibly inside the composite wooden beam 3 love.
  • the number and cross-sectional height of the individual beams forming the wooden beam 3 can be changed as desired, for example the lowest beam 3c can be omitted or a further beam can be placed on the upper beam 3a.
  • the length of the tab 7, the number and size of the dowel pins 9, and the number, size and arrangement of the press-in dowels 5 can be changed and optimized in accordance with the respective loads. Instead of welding it can Tab 7 with the support 1 can also be connected by other connection methods customary in steel construction, for example by screws.
  • the embodiment according to FIG. 5 differs from that according to FIG. 1 by two features which can also be used individually, independently of one another.
  • the lower beam 3b, 3c is supported not only against the side surface of the support 1, but also against a bracket 17 projecting from the support 1, which absorbs the vertical force acting downwards.
  • the vertical force is thus introduced into the support 1 via the bracket 17 and not, as in the embodiment according to FIG. 1, via the dowel bracket 7.
  • This has the advantage, among other things, that the nail plates 5 between the upper and lower beams 3a, 3b are relieved of the vertical force.
  • the second difference is that the dowel plate 7 is not welded onto the upper end surface of the support 1.
  • abutment plate 19 is braced against the tab 7 by a triangular plate 21.
  • the abutment plate engages behind the support 1 and guides it onto the dowel bracket 7 acting tensile force as a compressive force in the outer side surface of the support 1. Screws 23 indicated by dashed lines can connect the abutment plate 19 to the support 1 in order to fix the entire wooden beam 3 to the support 1.
  • FIG. 6 corresponds essentially to that of FIG. 5 with the difference that the console 17 is set lower and the lower bar 3b, 3c by diagonally inserted spacers 25a, 25b, 25c against the console 17 and against the side surface of the Support 1 is supported above the console 17.
  • the intermediate pieces 25a, 25b, 25c are connected to one another and to the lower beam 3c by nail plates 27.
  • the support of the lower beam 3b, 3c on the support 1 is solved by means of a bracket 17 in a similar manner to that shown in FIG. 5, with a small wedge-shaped intermediate piece 29 being inserted here.
  • the connection of the tab 7 with the support 1 is designed differently than in the previous embodiments.
  • two parallel coupling plates 31 projecting vertically downward are welded, each of which is provided with a push-through opening 33 for a coupling bolt.
  • the coupling plate 35 can be part of a T-profile piece 39 embedded in the column 1.
  • the corner connection is made simply by placing the wooden beam on the support 1 and pushing a coupling bolt through the aligned openings 33, 35.
  • FIGS. 5 to 8 have the advantage that they give a very simple to assemble and disassemble corner structure.
  • the entire composite wooden beam 3 with inserted dowel flap and connecting elements prepared thereon such as abutment plate 19 or coupling plate 31 can be prefabricated at the factory and then transported to the construction site. At the construction site, all that is left is to place it on the support and connect e.g. by means of screws or coupling bolts.
