Definitions

  • the invention relates to a method for connecting trusses or trusses, characterized in that the two bodies to be connected are joined together in such a way that the end of the first body, which has a hollow cylinder, is inserted into the bore of the second body and an explosive charge attached in the interior of this hollow cylinder is provided Detonation or explosion is brought, whereby above all the hollow cylinder is plastically deformed so that the two bodies remain rigidly connected to one another, and a device for performing this method.
  • space trusses Due to their static advantages and the favorable fire behavior, space trusses have an increasingly broad field of application. They are used for column-free roofing of halls and open spaces as well as for high-rise buildings and special constructions.
  • Space trusses consisting of rods and nodes, the rods having bolts at both ends and the nodes being spherical with threaded holes. Similar systems are e.g. connected by plate-shaped, block-shaped, cylindrical or cup-shaped knots.
  • the invention seeks to remedy this.
  • the invention solves the task of connecting rods and nodes of the space framework by detonation or explosion of a small charge Explosive (5) Fig.1, attached in the linking element so that as a result of the resulting pressure wave, plastic deformations occur on this linking element, which in a fraction of a second create a rigid connection between the node and the rod.
  • the cylinder (12) Fig.2 made of inert material (plastic, etc.) is used to position the load (11) Fig.2 and to improve the efficiency of the pressure wave.
  • the amount of explosives used is so small that no dangerous vibrations are to be feared, even for large trusses, created in inhabited centers.
  • Both cylinders were provided with identical triangular teeth over a length of 25 mm; the teeth were 2 mm deep and 2 mm wide.
  • Detonator No. 8 was used as the explosive charge, without additional explosives, ignited by a fuse (6) Fig.l.
  • the connected cylinders were loaded with a hydraulic press up to 235 N / mm 2 .
  • the two bodies deformed without loosening.
