Definitions

  • the invention relates to a junction connection for wooden bars of trusses, in particular space trusses, in which one-piece holding members for threaded bolts of the junction connection are glued in their profile adapted axial recesses in the ends of the wooden bars.
  • the node pieces are made of steel or light metal, while the rods are made of round or square timbers, which means that relatively inexpensive space trusses can be created, which many cases easily meet the static requirements.
  • Each of these versions uses several U-shaped brackets to hold the threaded bolts, which in one case are attached to the outside of a wooden rod by means of claw-shaped ends and screws, and in the other case are inserted into axial slots in the front ends of the wooden rods and by transverse pins or screws in held in this position.
  • junction connection in which a hollow truncated cone piece which axially displaceably receives the threaded bolt is fastened to a steel plate which in turn rests on the end face of the wooden rod, with this steel plate being at right angles several steel sheets are welded on, which are inserted in corresponding slots in the wooden stick and are fixed to the wooden stick by means of transversely driven nails.
  • a junction connection for wooden rods of trusses is also known, in which the node piece has integrally molded holding members with sawtooth-shaped surfaces which are glued into complementary surfaces on the ends of the wooden rods. Furthermore, two threaded bolts extend between the node piece and the front ends of the wooden rods in this embodiment.
  • a knot piece with molded profiled holding members is expensive to manufacture and, moreover, only allows a limited number of wooden rods to be connected.
  • the invention has for its object to further simplify node connections of the type described in the introduction and to further reduce the connection length between the rod ends and the node pieces.
  • each holding member consists of an extruded part with a sawtooth profile and has on its section facing away from the sawtooth profile an axial groove with a T-shaped clear cross section for receiving one or more threaded bolts which pass laterally e.g. Pins are locked.
  • the production of such holding members from an extruded part with a sawtooth-shaped profile is extremely economical and, furthermore, very short connecting lengths are achieved with such holding members.
  • Such a holding member can advantageously accommodate one or more threaded bolts for executing corresponding multiple connections.
  • each holding member consists of an extruded part with a star or spoke wheel-shaped cross-sectional profile, that the threaded bolt is held in the central part of the holding member with a star or spoke wheel shaped cross-sectional profile, and that the outer end face of this central part is the Forms a bearing surface for a drive sleeve that is connected to the threaded bolt in a rotationally fixed but axially displaceable manner.
  • This solution enables an extremely short connection length, which practically only corresponds to the length of a drive sleeve. In this case, too, the holding members can be achieved simply by sawing off correspondingly long pieces from the extruded part.
  • 10 denotes a node of a node connection in a space framework in which wooden rods 13 are used.
  • the metal e.g. Steel-made node piece 10 has a plurality of threaded bores 11 intersecting at its center, which are intended for receiving threaded bolts 12.
  • Two square wooden rods 13 are connected to the node piece 10 merely by way of example, and have holding members 14 for a threaded bolt 12 at each end.
  • the holding members 14 consist of an extruded profile, e.g. Aluminum separated parts, the length of which is dimensioned depending on the edge length of the wooden rods 13.
  • the holding members 14 have on their section serving for fastening a sawtooth-shaped profile 15 which is glued in this profile adapted axial wedge-shaped recesses 16 in the front end of the wooden rods 13.
  • a commercially available special adhesive for wood and metal can be used as an adhesive for this.
  • the recesses 16 are preferably formed continuously from one side to the opposite side, e.g. using an appropriate form cutter. This means that they are open on the side, which has the advantage that excess adhesive can escape there.
  • the holding members 14 also have a T-shaped longitudinal groove 17 on their section protruding from the front end of each wooden rod 13, into which the threaded bolt 12 is inserted with its head 18 and secured by two transversely arranged pins 19 in the central position shown in FIG. 2 is.
  • a driving sleeve 20 is used to screw the threaded bolts 12 into the threaded bores 11 of the node piece 10 ) extends.
  • This driving sleeve arrangement is known and therefore requires no further explanation.
  • the driving sleeve 20 rests with an end face on a flattened part of the node piece 10 and with its opposite end face on the surfaces 23 on both sides of the groove 17 with a T-shaped clear cross section.
  • the holding member 14 can also accommodate two threaded bolts 12 '(in the case of greater lengths also more than two threaded bolts). In this case too, the threaded bolts 12 'are secured against lateral emergence from the groove 17 by transverse pins 19.
  • the embodiment according to FIGS. 4-7 contains a holding member 14b for a threaded bolt 26 with a spoke wheel-shaped cross section, a threaded bore 28 for the threaded bolt 26 being provided in the central or hub-shaped part 27.
  • the holding member 14b is also preferably produced as an extruded part made of aluminum, and the individual holding members are separated from the extruded profile with a length such that a sufficiently large adhesive surface is achieved.
  • the threaded bolt 26 is designed as a differential threaded bolt, which is known in the case of junction connections of space frameworks and therefore does not require any further explanation.
  • the connection between the threaded bolt 26 and the drive sleeve 20, which is non-rotatable but permits an axial relative movement, corresponds to the exemplary embodiment according to FIG. 1.
  • the holding member 14b is fastened in the ends of the square wooden rod 13 by gluing into corresponding recesses.
  • a central axial bore 29 is provided in each end of the square wooden rod 13, from which slots 30 extend radially outward.
  • An annular recess 31 is provided coaxially with the bore 29.
  • the bore 29, slots 30 and the recess 31 are all worked out to a depth which corresponds approximately to the length of the holding member 14b (see FIG. 4).
  • the diameter of the bore 29 and the width of the slots 30 and of the annular recess 31 are dimensioned such that, when the holding member 14b is inserted, lateral gaps (FIG. 5) remain which serve to accommodate adhesives.
  • FIG. 5 shows that the gaps remaining between the inserted holding member 14b and the bore 29, the slots 30 and the annular recess 31 by means of a filling adhesive 34 or special adhesive 35 are filled out. These adhesives are commercially available. Since the slots 30 are laterally open to the outside, excess adhesive can advantageously be forced to the side when the holding member 14b is installed.
  • FIGS. 8 and 9 show a holding member 14c with a star-shaped cross section for the threaded bolt 26.
  • this holding member has a central part 36 with a threaded bore 37 for receiving the threaded bolt 26.
  • Uniform webs 38 extend radially outward from the central part 36.
  • the holding member 14c likewise preferably consists of an extruded aluminum part which is separated from an extruded profile in predetermined lengths.
  • This holding member is glued in a manner similar to the exemplary embodiment according to FIGS. 4-7 in an axial bore 29 in the front ends of the square wooden rod 13, from which slots 30 extend radially outwards.
  • the central part 36 of the holding member 14c is again received by the axial bore 29, while the webs 38 are seated in the slots 30. Between the holding member 14c and the bore 29 or the slots 30, as in the previous exemplary embodiment, there is sufficient space for receiving a suitable special adhesive 35 or filler adhesive 34, as shown in FIG. 8.
