Definitions

  • the invention relates to a flat and spatial connection system for connecting tension or compression rods in wood and steel construction.
  • connection nodes in trusses, bracing associations and under-tensioned systems are fundamentally problematic.
  • the geometrical relationships differ from case to case, the same applies to the forces to be transmitted and their distribution.
  • a universal system for forming such connection nodes is therefore difficult to implement.
  • a modular system that can be used universally and is suitable for connecting wooden beams, steel profiles and tension or compression rods does not yet exist.
  • the invention has for its object to propose such a versatile and variable system.
  • connection system with two circular washers as side plates and suspended anchor nuts offers particular advantages.
  • this connection enables completely variable directions of the tension members, an individual prefabrication of the junction points can be omitted. Rather, the connection is adjusted directly during assembly.
  • connection according to the invention in pairs to form rigid joints and frame corners of wooden beams.
  • the wooden beams are preferably connected with connecting bodies, such as those from the German patent 7 71 986.6 are known. Reference is expressly made to the disclosure content of this patent or the European patent with the publication number 0 263 350.
  • the use of these connector bodies in timber construction enables the connection of wooden beams via dowel bodies with an internal thread embedded in the end face of the beams.
  • the Allen screws mounted in the anchor nut according to the invention engage in this internal thread and thus anchor the anchor nut directly and directly on the wooden support.
  • connection system lies in its modular structure.
  • the anchor nut and side plates can be forged, but can also be made from cast iron. The choice of material depends on the stress and the area of application.
  • FIG. 1a and 1c show the two side views of an anchor nut 10.
  • a stepped bore 12 is arranged centrally in the anchor nut, into which an Allen screw 14 can be inserted.
  • the Allen screw 14 is indicated by dashed lines.
  • Two mutually parallel grooves 16 are milled into the anchor nut on the side of the central axis. The bottom of the grooves 16 is rounded, as can best be seen from FIG. 1a. Of the The radius of curvature of the grooves corresponds to the inner radius of the lateral annular plates in which the anchor body is hung.
  • the anchor nut can be forged, but it can also be made of cast iron. The choice of material depends on the stress and the area of application. In the event that smaller Allen screws are to be used for connection to smaller internal threads, appropriately adapted washers can be inserted into the stepped bore 12.
  • FIG. 2 An anchor body 20 is shown in FIG. 2, which can be welded to the side plates. For this purpose, it has lateral knobs or webs 22 which engage in corresponding recesses in the side plates and are welded to them. Apart from the knobs and webs, this anchor body corresponds in structure to the anchor body 10 described in connection with FIG. 1.
  • FIG. 3 it can be seen how the anchor nut 10 are hung between two side plates in the form of two circular washers 24.
  • the flanks of the armature body 10 lying against the side plates are plane parallel surfaces.
  • the inner free cross section of the annular washers is selected so that the Allen screws inserted into the armature body from the inside, which project radially outwards, can be tightened from the inside with an appropriate tool. It is not necessary to fix the anchor nuts on the circular washers. Rather, the anchor nuts adjust themselves under the action of the forces acting on them. They overlap with the grooves 16 over the inner edges of the annular disks 24.
  • three or more anchor bodies are inserted into the two annular disks 24.
  • connection can only be loaded under tension, ie for the compensation of forces acting radially outwards.
  • the radially inwardly loaded anchor nuts are supported on the plug and can therefore also be subjected to pressure.
  • FIG. 4 shows a plan view of the annular disks with anchor nut described in connection with FIG. 3.
  • the anchor body is shown in section.
  • the rounded profile of the grooves 16 is indicated by dashed lines.
  • Fig. 5 now shows the perspective view of the connection just described with three connected round steels and a connected wooden beam.
  • a connector body as described in German patent 37 71 986.6 or European patent with publication number 0 263 350, is embedded in the end face of the wooden support.
  • the Allen screws inserted in the anchor body engage in the internal thread of the connector body or in corresponding internal threads in the head of the tie rods 26. From FIG. 5 it can be seen particularly well that no pre-adjustment of the anchor body needs to take place. Rather, the anchor bodies adjust themselves during the assembly of the tie rod, they can be moved into any angular position.
  • FIG. 6 shows a perspective view of a connecting part for absorbing tensile forces from two planes forming an angle to one another.
  • the connecting part consists of two half circular washers, which are welded to a vertical plate 28 accordingly.
  • the anchor bodies are introduced into the free cross section in the form of a circular section and overlap with their grooves 16 the inner edges of the circular disks.
  • FIG. 7 and 8 show in perspective how the connecting part shown in FIG. 6 can be connected to a wooden support.
  • a connector body as is the subject of the German patent 37 71 986.6, is let into the end face of the wooden support.
  • Fig. 8 shows the wooden beam in its shape connected to the connecting part.
  • FIGS. 9 and 10 show a further application example for a connection with two circular washers.
  • Fig. 9 shows the structure in an exploded view, Fig. 10 in the assembled form. After insertion of the Allen screws (not shown), the free inner cross section of the circular washers is filled by a cylindrical plug 32. The plug prevents the anchor body 10 from moving inward under pressure.
  • the connection shown in FIGS. 9 and 10 can therefore be subjected to pressure and tension.
  • connection 11 and 12 show another variant of the connection using two right-angled side plates, between which the anchor nut is welded.
  • An anchor nut can be used, as was described in connection with FIG. 2.
  • the connection stiffens a truss corner.
  • the connecting part is positively inserted into a corresponding recess in the truss and is supported therein.
  • 12a and b show different views of the corner connection described.
  • Fig. 13 shows a T-connection of two carriers with connecting parts inserted in the corners of the T-connection, in which the side plates consist of quarter circle circular plates.
  • the circular ring plates 40 are welded to foot plates 42 running perpendicular thereto, which can be screwed to the truss girders in a conventional manner.
  • Fig. 14 shows a similar connection.
  • the side plates are half circular washers.
  • Two tension members 26 and a truss girder are connected to the washers.
  • a connecting body as described in the European patent with the publication number 0 263 350, is in turn embedded in the truss.
  • the free cross section in the interior of the annular disks is filled by a semi-cylindrical plug 44.
  • the anchor body 10 can not move inwards but are supported on the plug, so that pressure forces can be transmitted.
  • Fig. 15 shows the rigid connection of two wooden beams using a pair of connecting parts with right-angled side plates, in which the anchor nuts are inserted so that they have a common central axis, but are oriented in reverse.
  • the anchor nuts described in connection with FIG. 2 can be used here. That means the anchor nuts are welded between the side plates.
  • the two connecting parts can still be connected together. The bending stiffness and stability of the overall connection is thereby increased.
  • the holes that are used in the wooden beams to accommodate the connector body are indicated in the drawing.
  • Fig. 16 shows a perspective view of the rigid cross-shaped connection of four wooden beams, which is formed using a pair of anchor nuts with two circular washers as side plates. The connection is made in the manner already described.
  • Fig. 17 shows the rigid connection of two wooden beams that form an angle to each other.
  • the structure of the connection corresponds essentially to the structure described in connection with FIG. 15 with the only difference that the side plates are angled.
  • the connecting bodies that are inserted into the wooden beams are marked 46 in the exploded view.
  • FIG. 18 shows a corner connection which is constructed in the same way as the connections shown in FIGS. 15 and 17. The only difference is the use of more angled side panels.
  • FIGS. 19 and 20 show the perspective representation of a node from three carriers which have three different spatial axes.
  • the angled connection of the carriers is achieved by using circular washers with different radii.
  • the inner and outer radii of the circular discs lie on each other parallel cone shells.
  • the inner cone 48 is shown in FIGS. 19 and 20, it is designed as a plug and is inserted into the connection after assembly of the carrier, where it takes over the role of the cylindrical plug 32 or the semi-cylindrical plug 44 and introduced into the node Pressure forces.
  • Figures 21 and 22 show a connecting cross between two pull or push rods and two wooden beams with a right-angled wooden beam.
  • the semi-circular side plates, in which the respective anchor nuts are hooked, are welded to a central box.
  • a threaded hole In the face of the box there is a threaded hole that can be screwed to a connector body, which in turn is anchored in a wooden beam.
  • the tension and compression rods or wooden beams arranged in approximately one plane do not necessarily have to lie in one plane. As can be seen from the drawing, each of these supports can be individually deflected up to 90 ° from the horizontal plane.
  • the step in the bore 12 of the anchor nut 10 can also be shaped in the form of a dome.
  • a spherically shaped step can easily be created with a ball mill.
  • a washer is then inserted into the hole, the underside of which is curved accordingly.
  • the central axis lies in the plane of symmetry of the two plane-parallel side plates or annular disks.
  • connection system can in particular also be connected to wooden supports, using the connector bodies described in the European patent with the publication number 0 263 350. This can be done in the connector body screwed Allen screws of the connection system are secured against unscrewing by means of a keyway.
