Definitions

  • Connection device for surface construction elements or the like.
  • the invention relates to a connecting device for surface construction elements which can be fixed to one another at variable angles, in particular wall and / or ceiling elements, frames or the like, with profile rails which can be fixed in each case on the abutting edges of the surface construction elements and each have an open cross-section have arcuate Pxofil stained and hereby can be brought into mutual engagement, with several
  • OMPI Profile rails inserted into one another in this way can be fixed by bolts which can be inserted at the end.
  • the known arrangement therefore requires a pressure piece exerting a radially outward force in order to elastically deform the interlocking arc pieces in this way.
  • the bolts to be inserted on the end face are designed as rubber plugs, which are pressed together in the axial direction with the aid of a tensioning screw, thus achieving a radial expansion.
  • Another disadvantage is that when the plug is tightened, a subsequent change in angle is no longer possible, which can increase the assembly effort. If a torque is nevertheless applied, for example by mistake, the plunger-like tilting movement of the interlocking elbow pieces can occur as a result of the rotational movement prevented by the stopper, as a result of which the positive engagement can be blown up and the connection consequently falls apart.
  • the rubber plugs mentioned only cause a locally limited mutual contact.
  • the mutually interacting rails thus only have the desired mutual contact in the area of their ends, which can have a disadvantageous effect on stability and security against wobble, in particular in the case of rails of relatively long length.
  • the arcuate profile piece is designed in the manner of a crescent moon, this crescent moon enclosing approximately an angle of 180 °.
  • arcuate profile pieces also through two circular arcs offset with respect to one another, which have the same radius, are delimited and are extended at least at one end by a decorative arch extension, and that the bolts provided for fixation are designed to be pressure-resistant. Since the profile piece is extended by the arch extension and therefore encloses a larger angle than 180 °, the arch piece itself prevents a hinge formed by several nested arch pieces from falling apart, so that the edge claw of the pressure-resistant bolts can be dispensed with.
  • the problems encountered in the prior art advantageously no longer occur here.
  • the measures according to the invention clearly result in a hinge-like connection in which a subsequent change in the angle of the interlocking profile rails is readily possible.
  • a comparatively large number of profile rails can be nested one inside the other.
  • No radial bracing is required to achieve a clean fit and sufficient hold. This ensures full rotatability and the connection cannot be pushed apart by radial forces acting outwards.
  • the pressure-rigid fixing bolts that can be used here also represent relatively simple and therefore inexpensive components that can be easily and simply brought into position, which can make assembly work extremely easy.
  • the edge claw of the fixing bolts used for the first solution example practically forms a clamp which encompasses the rotatably engaging arc pieces, by means of which they are reliably held together and guided in the circumferential direction, so that a positive fit between the interlocking arc pieces is not required and even when tensile forces acting on the connection occur or when there are changes in angle, there can be no gaping or popping open of the connection.

  • the holding strip 6 is provided with an undercut groove 7 to enable a form-fitting fixing.
  • the groove 7 is generally used to receive a tensioning element provided with a hammer head of tensioning locks, not shown, which can be used in the plates 1 or the frames 2 in a manner known per se.
  • the outer surface 8 and the inner surface 9 of the arc piece 5 each describe an exact circular arc with the same radius r;
  • the center points M 1 , M_ or 2 , M. of these arcs are simply offset from one another by the thickest wall thickness, in a preferred embodiment approximately 2.5 mm.
  • the offset arcs form the shape of a complete crescent moon, whose greatest thickness is in the middle and the wall thickness of which decreases to both sides, which results in a high degree of flexural rigidity.
  • the curved profile piece 5 can end where the inner and outer circles intersect, or are approximated to one another to a wall thickness of approximately 1 mm. Since the crescent-shaped arc section 5 at
  • OMPI The embodiment shown in FIG. 2 encompasses an angle of approximately 180 °, the bolt 11 used to fix several nested profile pieces must have an edge claw 14, as shown in FIG. 4. Di se edge claw engages in the manner described above the edge of the rails and thus prevents them from falling apart after the hinge-like nesting under load.

  • the retaining bar 6 is suitably arranged so that its center lies approximately in the area of the intersection of the arcs with the radius. Since sufficient meat is thus available in this area, the circular arc describing the inner surface 9 can extend beyond this intersection point, in the exemplary embodiment shown, over the entire width of the holding strip 6.
  • two bolts 11 are arranged opposite each other in the region of each joint, which can be clamped together by tie rods 12, which are only indicated by their center lines.
  • the bolts 11 are made of pressure-resistant material and are simply inserted into the hollow space delimited by the nested arch profile pieces. The diameter of the bolts 11 is therefore to be dimensioned such that there is a corresponding sliding play.

  • the fixing bolt consists essentially of the Bo shaft 28 and the bolt flange 29, which are interconnected by means of a screw connection, not shown.
  • the B zen flange 29 has an edge claw 30.
  • the bolt shank 28 has an essentially cuboid cross-section, its corners being formed by rounded, elongated profile pieces 31 which are in axially parallel, dovetail-shaped recesses 32
  • OMPI IPO of the bolt shaft 28 are used.
  • the advantage of this construction is that the bolt rests only with its corner profile pieces 31 against the inner surface 9 of the arch profile pieces 5, so that the frictional forces are reduced, which contributes to easier assembly. Since the profile pieces 31 are interchangeable, the same bolt shafts can be used as a base body for connecting two or more profile rails, while the profile pieces are simply exchanged for wider or narrower profile pieces. This improves the adaptability of the fixing bolts to different cross sections, which result from the fact that two or more curved profile pieces 5 are nested one inside the other.

Abstract

L'objet de l'invention concerne un dispositif de liaison pour des elements plans de construction fixables l'un a l'autre avec des angles variables. Il s'agit en particulier d'elements de paroi et/ou de toiture, de chassis, qui possedent sur chacun des bords une partie profilee (4) qui se presente sous la forme d un arc ouvert ce qui permet de les fixer l'un a l'autre; par ces moyens les parties profilees (4) sont emboitables l'une dans l'autre et fixees frontalement par des goujons (11). Les parties en arc de cercle sont limitees par deux arcs pouvant etre transposes l'un par rapport a l'autre; ces deux arcs ont un meme rayon (r'); les goujons prevus pour la fixation sont precontraints et munis a une extremite d'un rebord (14) chevauchant les faces adjacentes des parties profilees en forme d'arc de cercle emboitees les unes dans les autres. Les parties profilees en forme d'arc de cercle peuvent egalement etre prolongees au moins a une extremite par un prolongement (10) decoratif; le prolongement est forme par une partie profilee qui est limitee par deux arcs pouvant etre transposes l'un par rapport a l'autre, ces deux arcs ayant un meme rayon. Par ce moyen on empeche qu'une charniere formee par plusieurs elements en forme d'arc emboites les uns dans les autres puissent s'ecrouler de sorte qu'on peut renoncer au rebord (74) du goujon (11).
