Definitions

  • the invention relates to a lattice-like spatial structure according to the preamble of patent claim 1.
  • Such spatial structures can be designed, for example, as supporting scaffolding or scaffolding.
  • the rods are welded, screwed or riveted to node parts or node plates.
  • These systems are complex and cumbersome.
  • These piston-shaped connecting parts are also too heavy and cumbersome, different knot parts are required, depending on whether rods are to be connected inside the structure, on an outer edge or on an outer corner. In all known constructions, assembly is also cumbersome and difficult because the connecting parts, for example screw bolts, are difficult to access.
  • the object of the invention is to create a lattice-like spatial structure, in particular a node element, with which all lattice structures which are very modular can be constructed from a few, standardized elements, namely only one type of rods that are identical to one another and only one type of node elements that are identical to one another are stable, statically reliable and can be assembled and disassembled quickly and easily.
  • the most important, central part is a knot element in the form of a hood.
  • the node element according to the invention is formed in one piece in the form of an equilateral-triangular hood X.
  • This knot hood X has an equilateral-triangular central part D, on the triangular sides d1, d2, d3 of which an angled square connecting arm, tab or wing A, B, C each connect (one triangular side d1, d2, d3 is therefore simultaneously the inner side of one of these wings A, B, C).
  • a connecting gusset E extends between two connecting tabs A, B, C, that is, the two side lines of two adjacent connecting tabs are integrally connected to one another by a connecting gusset E.
  • This knot hood can be pressed from sheet steel but can also be cast.
  • the connection tabs A, B, C are provided with holes H for pushing through connecting screws (see. Fig. 2, 3, 4).
  • One connecting tab A has two holes H, the other two B, C only one central hole H.
  • connection tabs A, B, C extended backwards behind the equilateral-triangular central part D, these extensions intersect at a common point, which, seen in plan view, lies in the middle of the central part D.
  • the connection tabs ABC (or their extensions) are perpendicular to each other.
  • FIG. 2 shows a "lattice point" in side view, a central knot crest X from the front and two lateral (similar) hoods X from the side / back can be seen.
  • These three knot hoods X work together with a base plate L cut out in a T-shape.
  • Five bars M are visible (horizontally to the left, horizontally to the front out of the image plane, horizontally to the right, diagonally to the left in front and diagonally to the right in front); a similar rear connecting hood could of course also be used to connect three further rods, namely a horizontal rear rod and two diagonal rear rods.
  • the horizontal bars are screwed together with two bolts, the other bars are screwed down with only one screw bolt each.
  • the base plate L can also be linear.
  • Fig. 3 shows schematically an inner "node” with a plurality of connected rods in the form of a multi-armed cross.
  • node hoods X are connected to one another above a horizontal central plane and four node hoods X are also connected below; each knot hood "cuts" a corner out of the room.
  • Four digonal upper rods M, four horizontal rods M and four diagonal lower rods M converge to form a single, complex knot "point" to this eight-armed cross. If the connection is turned through 45 or 90 °, spatial structures with three, four, pentagonal modules can be realized, the quadrangular being designed as a square or a rectangle.
  • the rods M are formed by tubes, the ends of which are flattened, in such a way that first side flaps 5 are folded inwards and then flattened from above and below.
  • a connection head M1 is thus formed in the form of a square with at least one push-through hole in the middle.
