  • PATENTED M1822 m2 saw a or a FIG. 73
  • the present invention relates to a connection for rods, particularly for erection of static structures, braced mast, lattice-work girders, or the like, in which the rod faces pointing toward each other within the range of the connecting point are braced relative to each other by a driven-in wedge in which, the reaction force of which is assumed by a hoop gripping the parts to be connected.
  • the tensioning forces can be further increased, if the section of at least one rod is thickened wedge-like towards its free end and a tension wedge equipped with an oppositely disposed wedge inclination is coordinated therewith.
  • the hoop is formed as a polygon, in the corner edge of which the one rod engages forcibly, the remaining comer edges are tensioned against its further connecting rods, by means of intermediately driven wedges, the one, wider wedge secures by a filling extension between two inner faces of the hoop the other wedge against cross-wise displacement.
  • the present invention brings about the advantage, that at least the one inner face of the hoop, pointing to the wedge driven-in between the rod and the hoop, is equipped with a sliding and protectionwall.
  • An advantageous structure form comprises thereby, in accordance with the present invention, the feature that the slideand protection-wall has glassfiber strands disposed in the direction of driving-in of the wedge and embedded in known manner in synthetic resin. It is thereby furthermore of advantage, in accordance with the present invention, when the slideand protection-wall is formed integrally of the same material with the hoop.
  • connection can be produced with appreciable speed.
  • the cross-sections of the loaded rods, struts, or the like are not subjected to a weakening interfering with the stability. This applies also for the zone of the notch maintained always small for the entrance of the holding cam, since the only local weakening, which is neglectable only, is compensated by the tensioning hoop grip, so that the nominal loads of the rod are completely absorbed. Weatherand temperature-influences do not bring about any interference with the connections.
  • the connecting points are capable of being loaded immediately after the mounting.
  • the point of junction constitutes a correct solution as to material of the connecting problem of the structures having most different crosssections out of the material glass-fiber-synthetic resin. It is particularly economical and has an unusually high safety degree. Also, the demounting is made possible with the preservation of the structural parts.
  • FIG. 1 is a longitudinal view of a point of junction on a braced pole
  • FIG. 2 is a section along the lines IIII of FIG. 1;
  • FIG. 3 is a section along the lines IIIIII of FIG. 1;

  • FIG. 15 is a section along the lines XVXV of FIG. 13;
  • FIG. 16 is an end view of a connection of the end of a strut with a rod carrier passing therethrough;
  • FIG. 17 is a top plan view of the connection shown in FIG. 16;
  • FIG. 18 is a section along the lines XVIII-XVIII of FIG. 16;
  • FIG. 19 is a side elevation of an oblique-angled connection
  • FIG. 20 is a top plan view of the connection disclosed in FIG. 19.
  • FIG. 21 is a perspective view of the bridge member.
  • connection at the point of junction comprises the main carriers 1 and the connecting rods 2 of layers of synthetic material reinforced by glass fibers of square cross-section.
  • diagonally extending connecting rods 2 are provided, which connect the main carriers 1, extending parallel towards each other by formation of point junctions with each other, to a braced pole.
  • the glass-fiber strands are symbolically shown by lines F. As can be seen, the glass-fiber strands extend in the longitudinal direction of the main carrier 1, as well as of the connecting rods 2.
  • the connecting rods 2 are equipped with angular sections 3, forming the free ends of the rods.
  • the sections 3, as well as the main carrier 1, are hoop 4.
  • the latter comprises glass-fiber strands F wound in peripheral direction and embedded in synthetic resin.
  • the hoop 4 is produced in a winding process without seam of so-called glass silk and is soaked in synthetic resin. It has the form of a polygon, in which a corner edge 4' as well as opposite thereto, two comer edges 4" and 4", are formed. The latter are connected by a diagonal extension of the hoop wall 4" (see FIG. 3).
  • the sections 3 are thickened towards the free end about for the amount x.
  • the wedges 5, 5', 6 and 6' are thickened towards one of its ends.
  • the wedges 5 and 5 have the width of the main carrier 1, and are as to theirwidth, slightly reduced, respectively.
  • the wedges 6 and 6 are formed still with an inclined end edge 6", which extends to the hoop wall 4". Accordingly, the wedge 6 and 6, respectively, supports the wedge 6 and 6', respectively, entering towards the former in the cross-wise direction.
  • a connecting rod 2 is rigidly tensioned with the main carrier 1 by means of a wedge 5 in the corner 4" within the hoop 4, in which the main carrier l is mounted in the corner edge 4.
  • This wedge 6 likewise has carrying faces inclined towards each other, whereby the sections 3 of the particular connecting rod, which is changed, is rigidly clamped.
  • the hoop 4 which is triangular in cross-section, has on the inside at the triangular edges, a plurality of holding cams 9 for the entrance into a gripped by a notch 10 of the rod 2.
  • This formation serves the itolerance-free fixing of the predetermined position of the connecting points.
  • This simultaneous pre-characterization permits practically a fool-proof construction.
  • the holding cams 9 comprise glass-fiber plates of synthetic material and are driven into corresponding slots in the hoop 4, so that they fix the section 3 of the rods 2, in which likewise fitting diagonal notches 10 are provided.
  • a distance plate is provided formed at their narrow longitudinal edges, which distance plate retains the sections 3 of the rods 2 in a position rigidly pressed towards the inner
  • the formation can be used also i in central longitudinal rods 1'.
  • the annular and 0ctagonal hoop 4, respectively, has engaging faces corresponding with the width of the rod sections 3.
  • the wedges 8 are provided in corresponding arrangement, particularly as shown in FIG. 7.
  • a slideand protection-wall 20 is interposed between the inner face 4""' of the hoop 4 and the wedges 5 and 5', (the wedges 6 and 6' have been omitted in the wedges 6 and6') between the inner face 4""' of the hoop 4 and the wedges 5 and 5', (the wedges 6 and 6' have been omitted in the wedges 6 and6') a slideand protection-wall 20 is interposed.
  • the latter has glassfiber strands F, extending in the driving-in direction of the wedges 5 and 5' and embedded likewise in synthetic resin.
  • the clamping faces of the wedges 5 and 5' enter engagement accordingly exclusively with glassfiber strands F and F extending exclusively in the driving-in direction. In this manner it is avoided, that the hoop 4 tears parallel to the winding direction of its glass-fiber strands.
  • hoop 4 permits to form the slideand protection-wall 20 practically of the same material as the hoop 4. In such cases, also any slight displacements of the slideand protection-wall are avoided.
  • a cross-shaped intermediate member 13 is provided, the tabs 14 and 14' of which are clamped to each other, on the one hand, with the one rod 1 and, on the otherhand, with the other rod 2, again by using the hoop and wedge 5. It is favorable thereby, if the glass-fiber inserts of the cross-shaped intermediate member 13 extend superposed relative to each other in the median range. The thereby increased distance (see FIGS. 10 and 13, respectively) of the oppositely disposed rod engaging faces serves as space for driving-in the wedges 5 and 5'. There also are the tabs 14 and 14' formed on their faces 15 wedge-like.
  • the supporting angle 16 overlapping the cross-connection is provided, which likewise is made of a profile of synthetic material enforced with glass fibers. Also here are the straight lined ends of this supporting angle 16 rigidly clamped by the use of a hoop 4 and of the wedges 5 with the rods 1 and 2, respectively. As further shown in the lower part of FIG. 13, the supporting angles 16 can by example also serve as feet for anchoring of the rod 2.
  • a strut 2' on a running through rod 1 in cross-position to the latter.
  • the end of the rod 2' which engages with its face on the rod 1 is overlapped by a bridge member 17, which has end sections 18 extending parallel to the rod 1 and which is mounted by means of a hoop 4 each in addition to the wedge on the rod 1.
  • the bridge member 17 has a glass-fiber strand arrangement corresponding with the rod 1. Between the wedge 5 and the inner faces 4'" of the hoop 4 there is interposed the slideand protection-wall 20.
  • the face engagement of the strut 2' is disposed with its diagonal cross-sectional plane perpendicular to the strut face, and also a flattening 19 is obtained.
  • the edge of the strut 2' disposed opposite the flattening 19 is arranged forcibly in an open angle of the bridge member 17.
  • the end sections 18 of the bridge member 17 are wedge-like pointed.
  • the mentioned bridge member can also serve in a particular design to engage the face of square struts with that of the rod 1 and to connect cross-wise thereby the same.
