Definitions

  • the invention relates to a knot-en-rod system for flat and curved support structures with hollow profile bars and with knot bodies consisting of hollow bodies, which can be releasably connected to the hollow profile bars by means of screw connections and by means of which an at least partially closed, interconnectable pipe system can be produced by Feed and discharge can be fed with liquid or gaseous medium.

  • a good connection can be made between the hollow profiles and the node elements, especially when it comes to hollow profile elements with a circular cross section.
  • this connection requires several coordinated connecting parts, which make the node-rod system complex and cost-intensive.
  • Another disadvantage of the known system is that it is only indirectly protected against fire or overheating. This is achieved in that, if necessary, cooling medium is passed through the hollow profiles.
  • node-rod system should be able to be converted by simple measures so that it can serve as a fire extinguishing system.
  • the knot bodies are cup-shaped or ring-shaped and have working and connecting surfaces on their outer surfaces which can be tightly connected to the working and connecting parts of the hollow profiles or adjacent knot bodies, in that these surfaces each have at least one Have opening for connecting screws, which have a preferably axial, the knot interior connectable to the interior of the profile rods connected to the knot body, and that the knot body each have at least one opening which can be sealed by means of a cover releasably connectable to the knot body.
  • connection between the profile bars and the knot body is therefore made such that the connecting screws are brought through the opening into the interior of the knot body and are then arranged in the openings provided for the connecting screws. Then the connection between the screws and the profile bars is established. Finally, the lid is tightly connected to the node body. Such a connection between the node body and the Profile bars are therefore suitable for guiding a medium from one profile bar to another.

In these cases, the longitudinal central axis of the connecting rods is inclined with respect to the working and connecting parts of the node bodies.
  • the production of the connections between the knot bodies and profile bars can also be improved in such a way that the opening of the knot body is dimensioned such that the connecting screws can be inserted from the inside to the outside through openings in the knot body designed as bores.

This element also prevents the rods from twisting. If it is a knot body, the outer connection surface of which is not square but rectangular, then the knot and rod are connected by two screws.

Abstract

Le système décrit est destiné à des structures porteuses planes et courbes comportant des barres profilées creuses (12, 13) et des corps nodaux (18, 20) constitués de corps creux, qui peuvent être assemblés de manière amovible avec les barres profilées creuses (12, 13) au moyen de fixations vissées (22, 24, 26), et grâce auxquels on peut réaliser un réseau de canalisations interconnectables et au moins partiellement obturées, ce réseau pouvant être rempli d'un milieu fluide ou gazeux au moyen d'une conduite d'amenée et d'évacuation. Les corps nodaux (18, 20) présentent une configuration en cuvette ou en anneau et possèdent, sur leurs surfaces extérieures, des surfaces de travail et d'assemblage (30, 32) destinées à l'assemblage étanche avec les parties de travail et d'assemblage (34, 36) des profilés creux (12, 13) ou des corps nodaux (18, 20) adjacents. Ces surfaces (30, 32) présentent respectivement au moins un ajour (40, 42) pour les vis de fixation qui possèdent un ajour (60, 62), de préférence axial, reliant l'espace intérieur nodal (50, 52) avec l'espace intérieur (54, 56) des barres profilées (12, 13) assemblées avec le corps nodal (18,20). Les corps nodaux (18, 20) sont respectivement pourvus d'au moins une ouverture (64, 66, 68) obturable hermétiquement au moyen d'un couvercle (70, 72, 74) se fixant de manière amovible sur le corps nodal (18, 20).
