  • the node bodies lie in the fully deployed working state of the node-rod system on a common surface and define a grid of even polygons, while in the partially unfolded working position they define two surfaces running parallel to one another, such that the Node body each of a polygon alternately lie on one or the other surface and that the knot bodies lying on a common surface are held stationary by means of a connecting or stiffening body.
  • the node-rod systems When unfolded, the node-rod systems form a modular series of even polygons. In the unfolded state, the knot-rod system forms a network, the mesh of which is formed by pressure rods that can be connected to the knot bodies by means of swivel joints.

  • the elements of the node-rod system are designed as hollow bodies and are connected to the node bodies 373 in a medium-tight manner.
  • Such an integrated square grille can be designed as a sprinkler system, as shown in FIGS. 38, 39 and 40.
  • Both the knot bodies 380 and the elements 381 have forks 382 and 383, respectively. Fork joints can be produced using these forks 382 and 383.
  • the knot body 380 which is designed as a multi-part shell body, consists of a base body 385, which is surrounded by projecting legs 386 and 387 with bores, by a cover 388 and by a base 389.
  • the elements 381 are hollow bodies which can be connected to the base body 385 by means of pipe pieces 390 made of elastically deformable material.
  • the two ends of the pipe pieces 390 can be connected to threaded sleeves 391 and 392 by means of clamping elements 394 and 395.
  • the cover 388 and the bottom 389 can be detachably connected to the legs 386 and 387 by means of screws 398 and 399.
  • the bottom 389 has a central bore 400 with a thread into which a sprinkler nozzle 401 can be screwed.
  • the entire node-rod system can therefore be supplied with medium and can thus serve as an extinguishing system and also as a heating or air-conditioning system, the node-rod system accommodating outlet nozzles for air conditioning system that can be equipped with water or air.
  • Elements 381 can be connected to the legs 386 and 387 by means of rivets 404 and 405.
  • 41 and 42 show node-rod systems which can be used as busbar grids and can be suspended on a ceiling 410 by means of rods 411.
  • 42 is constructed essentially as the node body according to FIG. 40, but it has no base body. It consists of four legs 421 and 422 with bores 423 arranged at right angles.
  • the base body can be locked from above by means of a plate 425 and from below by means of a plate 426. Screws 427 and 428 are provided for this.
  • the node body can receive a busbar connector 430 with four heads 431 that engage the elements 420. How the elements 420 look in cross section can be seen in FIG. 41 at the top right, where guide rails 440 are provided for the springs 433 of the heads 431.
  • the main advantage of the node-rod system is that no cables have to be laid, but rather plug and screw connections of standardized parts.
  • a knot body which is designed as a multi-part shell body. It consists of a base body 520, a cover 522 and a base 524. Between the cover 522 and the base body 520 or between the base 524 and the base body, a seal 523 is arranged in each case, which seal the interior in the effective state of the node body.
  • the cover 522 and the base 524 can be detachably connected to the base body 520 by means of screws.
  • a nozzle 525 can be screwed to the base 524.
  • the base body 520 has radially projecting forks which can accommodate the elements 502 and 505.
  • the elements 502 to 505 have axial bores 510 and 511 with thread, can be screwed into the screws 512 are. Between the ends of the elements 502 to 505 on the string side and the knot bodies 520, pressing bodies 530, 532 with bores for the screws 512 are arranged. The screws 512 are screwed in from the inside. The angle of inclination of the elements 502 to 505 is defined by the wedge angle of the pressing bodies 530 and 532.
  • the proposed knot-rod system can be used in many ways (cf. FIGS. 19 to 24).
  • Their particular advantage is the high degree of stiffening in the case of knot bodies and rods, so that e.g. on a construction site, the node bodies only need to be tensioned.
  • the node-rod systems are assembled in workshops, while on the construction sites they only have to be unfolded and the node bodies have to be stiffened.
  • Link networks with square and hexagonal or square and octagonal meshes are suitable for multi-layer trusses made of foldable node-rod systems.
  • At least three knot-rod systems are always connected to each other in a shear-resistant manner.
  • the spatial foldability of all even polygons as individual figures or as modular flat structures leads to a large number of structures which can be connected to one another and can assume more or less stable states. The number of possible combinations is therefore very large.
  • Link networks can be used when used as composite constructions (FIGS. 25, 26 and 27).
  • a shear-resistant connection with concrete or another solid base can be made using head bolts, dowels or the like. With these constructions, finished concrete slabs also come into consideration, so that the production of a complete composite construction can take place quickly.
  • the knot-rod system is located in the cavity between the two levels as a spacer. A cavity produced in this way is ideally suited for installations, for example, and is also protected against the effects of fire and corrosion.
