Definitions

  • the invention relates to a knot connection for rod structures with more than two bars connected in a knot, which protrude into a metal box which can be filled with a hardening casting compound and which end in the metal box with a form-fitting end section, the section of which may be deformed, in particular constricted.
  • node connections such as e.g. has become known from GB-A 271 709
  • a relatively large metal box is required so that the tensile forces acting on the rods can be absorbed.
  • the outer radius of e.g. a metal box shaped as a sphere or similar convex shell must be at least as large as the dimension with which the rods protrude into the metal box.
  • the resulting bulky knots are not only a visual disadvantage, but also cause problems with the filling by the potting compound.
  • a corresponding amount of the expensive casting compound is required, the weight of which plays a significant role in larger rod structures, particularly in steel structures, and increases the overall expenditure.
  • AT-A 339 094 The same problem exists with a node connection as is known from AT-A 339 094.
  • the invention has for its object to provide a node connection of the type mentioned that manages with smaller nodes.
  • the projections of the metal box taper in a step-like manner.
  • the projections start in a star shape from a convex central part of the metal box, which is preferably approximately spherical or flattened spherical.
  • the projections tapering towards the openings of the metal box are composed of a series of hollow prisms with a cross section decreasing towards the openings and are firmly connected to one another and to the convex central part of the metal box or are formed integrally therewith.
  • the tensile forces acting on the rods can be transmitted from the form-fitting end sections of the rods to the metal box via the pressure cone formed in the hardened sealing compound, as if it had the dimensions of the projections as a whole.
  • the steps of the step-like projections take over the tensile forces as such from one step to the other.
  • the compressive forces acting on the rods are directly introduced into the hard sealing compound via their closed ends, which are supported on the ends of the other rods and on the inside of the metal box.
  • a node connection comprises a metal box 1 with a convex central part, approximately in the form of a flattened ball. From the central part, projections 3 tapering in a star shape extend to openings 2 of the metal box 1.
  • an opening 2 for a rod 4 in the form of a square tube and a further opening 2 for a rod 4 in the form of a round tube are shown.
  • An advantage of the knot connection according to the invention is that the rods 4 do not need to have the same cross section. Diagonal bars can e.g. are designed to be weaker than belt rods.
  • rods 4 end in the metal box 1 with a form-fitting end section which is constricted. From the sectional representations of constricted end sections of rods 4 in FIGS. 2 to 4, it can be seen that the constriction is formed by folding the tube wall without weakening or changing its cross-sectional area.
  • each constricted end section of the rods 4 two oppositely conical insertion parts 5 and 6 are arranged on opposite sides of the constriction.
  • the constriction is adapted to the shape of the insert parts 5 and 6.
  • the two insertion parts 5 and 6 are clamped longitudinally displaceably by a tension member 7 in the form of a high-strength screw or several such screws (FIG. 4) within the end section of the rod 4, so that they fit snugly against the inner wall of the pipe on opposite sides of the constriction .
  • a filling opening 8 is provided for the filling of the hardening casting compound.
