Definitions

  • the invention relates to a detachable connection for wooden beams according to the preamble of claim 1. It has been known for some time to replace carpentry-made, conventional beam connections by prefabricated elements which can be assembled and fixed directly on site without additional .working measures. Connections of this type have the advantage that cross-sectional weakenings are greatly reduced and that the mechanical load-bearing capacity of the connection can be determined precisely by calculation.
  • a prefabricated connection has become known from the Austrian patent specification No. 316,833, in which each fastening plate inserted into the end of the beam is provided with at least one eyelet on the connection side.
  • the same plates provided with eyelets are also provided in the end of the beam to be connected, the eyelets on the two sides engaging with one another and in alignment with one another in such a way that a connecting bolt can be pushed through the eyelets.
  • the remaining play between bolts and eyes is poured out with a synthetic resin binder.
  • a disadvantage of this connection is, for example, that its precision cannot meet today's requirements.
  • it is difficult to remove the connecting bolt once the eyelets are filled with synthetic resin binder.
  • the manufacture of the fastening plates is relatively complex since the eyelets have to be welded on separately.
  • This connection is also unsatisfactory with regard to the static properties, since an absolutely precise interlocking of the eyelets cannot be achieved in practice.
  • Another object of the invention is to further simplify assembly and to ensure a large number of different connection options with the same components.
  • the necessary preparatory work on the beam ends to be connected should be able to be largely programmed and automated, which considerably simplifies the manufacturing process.
  • connection which has the features in the characterizing part of patent claim 1.
  • the mounting plate obviously does not have to be equipped with additional elements such as Eyelets etc. for receiving a connecting bolt. Rather, the connecting bolt is inserted directly across the mounting plate, which considerably simplifies its configuration. The fit and the mechanical strength of the connection can also be significantly improved. Due to the flat overlapping of the overlapping areas of the connector and the mounting plate, torsional forces can also be transmitted without any play.
  • a seamless butt joint results from the fact that the mounting plate is completely countersunk in the beam end and that holes are arranged in the beam end for receiving the connecting bolts, which lie on the same axis as the congruent holes of the mounting plate and connection piece, and that a recess for receiving is in the beam end the connector is provided.
  • This arrangement also has the advantage that the connecting bolt or bolts is or are not only supported in the connector and in the fastening plate, but also in the end of the beam.
  • the connecting piece is also a plate which engages in the end of the beam to be connected. In this way, only one slot has to be milled or cut out on each of the two ends of the beams to be connected.
  • Such a connection can be further improved by the fact that the connecting piece and the fastening plate are identical components, the overlapping edge region on which the congruent bores are arranged running on a plane which is parallel to the plane of the remaining plate by about half the wall thickness is offset.
  • the connection can thus be realized on both sides of the joint with a fastening plate, one fastening plate being inserted in the opposite direction to the other.
  • the parallel offset of the edge area with the holes ensures that the plates themselves run on the same plane. This is particularly advantageous for static and manufacturing reasons.
  • the connecting piece is an approximately prismatic connecting strip.
  • a connecting bar can be manufactured precisely from steel, for example, and provided with the necessary bores for receiving the connecting bolts.
  • the connecting bar can be attached practically anywhere and gives the connecting bolt one sufficient lateral stability.
  • the connecting bar can be used in a particularly versatile manner if it has bores, arranged transversely and offset to the bores for the connecting bolts, for receiving fastening elements with which the connecting bar can be connected to the part to be connected to the beam end.
  • the connecting bar can be screwed into a steel plate, for example, or anchored in a concrete base.
  • fastening elements are threaded bolts and if countersunk nuts for adjusting and fastening the connecting strip are arranged on both sides of the bores for receiving the threaded bolts in the connecting strip.
  • the relative position of the connecting bar can be changed in this way. This is advantageous, for example, for connections for large loads, where the deflection at the connection must be taken into account.
  • a particularly stable and torsionally rigid connection results when two fastening plates are completely sunk in the beam end, when the connecting bar lies in a recess between the fastening plates and when holes are arranged in the beam end for receiving the connecting bolts, which lie on the same axis as the congruent ones Holes in the mounting plates and in the connecting bar.
  • connecting bolts are inserted into the congruent bores without play, no additional securing elements have to be provided for the connecting bolts. Rather, the connecting bolts are inserted with a slight press fit, so that on the one hand they hold themselves and on the other hand can be easily knocked out again in the event of disassembly.
  • a wooden beam 1 is connected to the part 6 to be connected via two fastening plates 2 and a connecting bar 13 serving as a connecting piece, which in the present case is a transversely extending beam.
  • Another beam could be connected to the rear of the transverse beam in the same way, whereby the connecting strips 13 could be fastened with continuous threaded bolts.
  • the fastening plates 2 are embedded in slots 3 at the beam end 4 and fastened in a manner known per se with fastening elements 5 running transversely through the beam end and the fastening plates.
  • the attachment of the connecting bar 13 is described below with reference to Figure 2.
  • the connecting bar 13 engages in a recess 11 in the beam end 4 between the two fastening plates 2.
  • the clear width between the two fastening plates 2 corresponds approximately to the width of the connecting bar 13.
  • congruent holes 8 are arranged, which are continued in holes Find 10 in end of bar 4.
  • connecting bolts 9 are inserted after the joint has been joined.
  • the diameter and number of connecting bolts vary depending on the load capacity of the connection.
  • the connecting bolts can consist, for example, of steel, confessional metal or also of a suitable plastic material.
  • a connecting pin 9 extends over the entire width of the beam end 4. In certain applications, however, it would be conceivable to insert a connecting pin from both sides, which extends into the connecting bar 13.
  • the mounting plates 2 themselves are designed as flat, approximately rectangular plates, but can also have a different configuration depending on the application.
  • connection of the connecting bar 13 is shown in Figure 2. Details of the connecting bar can be seen from FIGS. 3, 4 and 5.
  • Fastening elements 15, which in the present example are threaded bolts which are carried out by the part 6 to be connected, are used to fasten the connecting strip.
  • 13 holes 14 are in the connecting bar arranged, which are arranged approximately transversely and offset to the holes 8 for the connecting bolts.
  • Countersinks 19 are arranged on both sides of the bores 14. The recesses serve to receive nuts 16, with the aid of which the connecting bar 13 can be fixed and, if necessary, adjusted.
  • the connecting bar 13 can be positioned relative to the connecting part 6. This is particularly the case if the connection is intended for large loads and if any deflection at the connection has to be taken into account.
  • the connecting strip 13 can be inclined at a certain angle a, as shown, so that the beam 1 also assumes a certain inclined position without load. When the load is applied, this inclined position is compensated for and the bar is pressed into a horizontal position.
  • the connection bar 13 is adjusted by means of the inner nuts 16 ', with the aid of which it is also possible, for example, to prevent the connection bar from being pressed onto the part 6 to be connected.
  • the nuts cannot be tightened with a conventional wrench anyway, their external configuration can also be cylindrical, as shown in FIG. 5.
  • Cross slots 17, in which a tool can be inserted, are used to tighten the nuts.
  • the nuts can also have a different configuration or, for example, additional securing elements such as spring washers and the like can also be used.
  • the recesses 19 in the connecting bar 13 can also accommodate a screw head, for example. This is conceivable, for example, if a connecting bar 13 is screwed onto a steel beam, or if 6 threaded sleeves are inserted into the part to be connected, into which screws screws can be screwed.
  • the connecting strip 13 can be designed particularly advantageously as a standard component which can be used for various connections. For example, it is not absolutely necessary to provide each bore 14 with a fastening element 15. A particularly advantageous dimension has resulted in a height of the connecting bar of 55 mm and a width of 40 mm.
  • the length of the connecting strip can be variable depending on the number of bores present, the bores being able to be arranged, for example, at intervals of 40 mm.
  • FIG. 6 Another embodiment of the invention is shown in Figure 6.
  • connecting bolts 9 are inserted, which also extend through the beam end 4.
  • This type of connection advantageously uses specially designed fastening plates, as shown, for example, in FIGS. 7 and 8.
  • the edge region 12, on which the bores 8 for receiving the connecting bolts 9 are arranged, is somewhat bent and arranged on a plane which runs parallel to the plane of the remaining plate.
  • the difference between the two levels corresponds to approximately half a panel wall thickness. If two such plates are joined side to side as shown in FIG. 6, the plates lie on a common main plane, which is particularly important for structural reasons.
  • FIG. 10 shows a variant with two connecting pieces 7 on the same fastening plate 2.
  • the connecting pieces consist of a plate 20 and a tab 21 which is welded on transversely and approximately on the central axis of the plate.
  • the plate 20 is sunk into the surface of the part 6 to be connected and attached there. Screws on a bolt circle on the plate and a central bolt which penetrates the part 6 to be connected are used for fastening.
  • the tab 21 has bores for receiving the connecting bolts 9.
  • FIG. 9 shows, for example, the prepared beam end 4 in the exemplary embodiment according to FIG. 1 before the fastening plates 2 are inserted. Slots 3 are milled into the beam end 4, into which the fastening plates 2 can be inserted. The recess 11 serves to receive the connecting strip 13, which is also milled out. The bores 10 for receiving the connecting bolts 9 are already being prepared. These pre-drilling and drilling operations can obviously be carried out on a numerically controlled woodworking machine, which considerably rationalizes production.
