  • the angular position of the wooden rods 3 is selected, accordingly, the recesses 18 and the through holes in the curved bottom 4 to install.
  • the chamfer 11 prevents unwanted resting of the wooden rods 3 on the bottom of the recess 18.
  • the parallel threaded wood screws 5 serve, as already mentioned, the screwing of the wooden rods 3 with the base member 6 and enforce the through holes of the curved bottom. 4
  • Fig. 15 shows an alternative embodiment of the mutual support or spacing of two plates to form a component resp. Walls, roofs, ceilings or floors serving device 1.
  • the connected to the base element 6-for example by means of wood screws-Distanzlement 31 has in comparison with the base element 9 in FIGS. 1 and 2 no inclined abutment surfaces 16 but a rectangular recess 19 formed of three vertical guide surfaces, on, on which the arrow-shaped cut ends of Holtstäbe 3 are each employed and parked on the base element 6.
  • the node element 2 can be by a positive in- resp. Joining the items together in a simple and precise way.
