Definitions

  • the invention relates to a node element and a truss rod for space trusses.
  • a node element which has a pair of parallel plate-shaped parts for each truss rod to be connected to it, and a truss rod which is flat at its ends and is designed to fit between one of the pairs of plate-shaped parts.
  • the flat rod ends are each inserted between one of the pairs of plate-shaped parts and clamped between these parts by a screw or rivet (DE-OS 1 609 538).
  • 1 is a plan view of a truss node
  • Fig. 3 is a plan view of another embodiment of a truss node.
  • O PI 4 shows a section along the line IV-IV in FIG. 3,
  • FIG. 7 shows a section along the line VII-VII through the truss rod end in FIG. 5.
  • a spherical node element body is composed of two parts 1 and 2, which are held together by a screw 3.
  • Part 1 has the shape of a hemisphere 4 with projections 5 formed at intervals from one another, which are parts of ball wedges cut off at 45 ° to the ball center 6.
  • the boundary between the hemisphere shape and one of the approaches 5 is indicated by a dotted line 7.
  • the other part 2 has the shape of a spherical cutout (spherical cap) 8 with integrally formed lugs 9 which engage between the lugs 5 and likewise form parts of spherical wedges.
  • the boundary between the spherical cutout shape and one of the lugs 9 is indicated by a dotted line 10.
  • each projection 9 and one of the surfaces 14 which extend on the hemisphere base 7 between two approaches 5 form a pair of adjacent or adjacent (see wu) interfaces of parts 1 and 2.
  • Die in FIG. 2 the upper end face 15 of each attachment 5 and one of the surfaces 16 extending between two attachments 9 on the jacket 10 of the spherical cut-out shape 8 form further pairs of adjoining or adjacent (see also) boundary surfaces.
  • the wedge surfaces (side surfaces) 18 of adjacent lugs 5 and 9 abut one another.
  • a cavity 20 and 21, directed towards the ball center 6, is formed, in which a lug 23 of a truss rod 24 which is adapted to it sits and is held in a force-locking manner or, according to FIGS.
  • a lug 23 of a truss rod 24 which is adapted to it sits and is held in a force-locking manner or, according to FIGS.
  • the cavities can extend in the circumferential direction (based on the axial line of the screw 3) up to the wedge surfaces 18, so that the surfaces 13, 14 and 15, 16 of the interface pairs do not meet each other or only between the inner end of the cavity 20 or 21 and touch the hole provided for the screw 3 and are otherwise adjacent.
  • the extension 23 of the truss rods 24 is a plate, which is partially inserted into the tubular rod body 25 (FIGS. 5-7) and trapezoidally tapered at the end protruding therefrom, which plate is welded into slots of the tubular rod body 25 and at sufficient inner pipe diameter can also be welded to the inside of the pipe.
  • the extension 23 can also be formed on a peg inserted into the tube, which advantageously has one or more holes which make it possible to protect the truss rod provided with the extensions from rust on the inside by hot-dip galvanizing.
  • the projections 23 can also be provided with projections, for example humps, instead of with depressions (FIGS.
  • a spherical node element body is composed of three parts 31, 32 and 33 which are held together by a screw 3.
  • the part 31 has the shape of a hemisphere;
  • part 32 is a ring-shaped body with a flat surface 36 lying against or adjacent to flat surface 35 of hemisphere -31. It is circumferential by a spherical zone and on its side facing away from hemisphere 31 by a conical one Area 37 delimited with the cone tip lying in the ball center 6.
  • the part 33 is a spherical section, the conical surface 38 of which adjoins the surface 37.
  • the spherical shape is technically expedient and aesthetic, but it is not required to function.
  • the upper half in Figs. 2 and 4 can e.g. can also be limited like a polyhedron, while the lower half can be designed largely as desired.
  • the knot elements shown in FIGS. 1 to 4 are designed for four belt bars lying in one plane and for four diagonal bars on one and the same side of the belt plane.
  • the embodiment according to FIGS. 3 and 4 can easily be carried out for a further four diagonal bars on the other side of the belt plane, by replacing the part 31 by a part that is the same as the part 32 and a part that is the same as the part 33, which is a mirror image of the ones Parts 32 and 33 are to be arranged.

Abstract

Un élément de noeud sphérique est formé de plusieurs parties (31, 32, 33) retenues par une vis (3), parties qui se touchent en des surfaces limites (35, 36) situées dans un plan contenant le point nodal géométrique (6) et qui se touchent une à une en des surfaces limites (37/38) inclinées par rapport à ce plan et orientées vers le point nodal (6). Des évidements pratiqués sur ces paires de surfaces limites (35/36 et 37/38) permettent la formation, sur le côté extérieur de l'élément, de cavités (20, 21) ouvertes et orientées vers le point nodal géométrique (6); ces cavités reçoivent chacune par adhérence et/ou par blocage un talon (23) d'une extrémité de barre de treillis (24) qui leur (20, 21) est adapté.
