Definitions

  • This invention relates to a mechanism having the features of the preamble of claim 1.
  • An object of the present invention is to eliminate these drawbacks. It gives a solution to the connection problem of the pipe in a simple and economical way.
  • the pipe is in contact with the bearing neck of the intermediate part and, at same time, the face of the intermediate part is in contact with the node of the space structure.
  • the pipe and the node are tightened on the intermediate part.
  • the advantages of this invention are that the extra aesthetic requirements are satisfied at low cost, the required twisting force for the tightening is small due to the large diameter of the intermediate part, and that the penetration depth of the bolt into the node is long, which allows connection of pipes to nodes made of material with low strength (e.g. aluminum, plastic).
  • Figure 1 shows a part of a structure with connection elements and pipes where the mechanism is used according to the invention.
  • Figure 2 shows a longitudinal and a cross section of the mechanism according to the invention before the bolt screwing.
  • Figure 3 shows a longitudinal and a cross section of the mechanism according to the invention after the bolt has been screwed.
  • the structure according to figure 1 is called three dimensional structure or space structure and comprises the connecting elements, which are called nodes, and the bars 9.
  • the structure according to figure 1 is useful for the construction of buildings with extra aesthetic requirements, such as exhibition pavillions, shopping centers, shops, covered sports facilities, airport halls, hotel facilities, tourism facilities, universities, theaters, museums, libraries, etc.
  • the nodes are hollow spheres 1 with partial flat surfaces 11, distributed on their outer surface, bearing threaded radial holes 10.
  • Bars comprise one pipe 9 and two connection mechanisms 12, which connect the bar ends to the nodes.
  • connection mechanism 12 comprises a bolt 8, a pin 4, an intermediate part 3, a circular disc 7, a washer 5, and a spring 6.
  • the bolt 8 bears a hole for the passing throught of the pin 4.
  • the intermediate part 3, with a cylindrical section outside diameter 15 equal to the external diameter of the pipe 9, has a bearing neck 13 in order to be rotated about the pipe axis and two opposite grooves 14 wherein the pin 4 moves.
  • the circular disc 7 is welded inside the pipe with a circumferential weld 16 and bears a hole 17 for the passing through of the bolt 8.
  • the washer with the neck 5 has two opposite tooth-shaped projections 18, which enter into the grooves 14 of the intermediate part.
  • the two bolts 8 (one for each connection mechanism) are passed inside the pipe through the other end so that their heads 19 are in contact. Then another circular disc is placed at the other end of the pipe and is welded. Holding the pipe at vertical position and shaking it, and with the aid of the chamfer 20 of the circular disc 7, the bolt end passes through the hole 17 of the circular disc 7.
  • the spring 6, the washer, the pin 4, and the intermediate part 3, are then placed consequently.
  • the intermediate part 3 is held in position by wrapping up its contact with the pipe 9 with an adhesive plastic tape.
