Definitions

  • the invention relates to a skeleton, in particular for dome-shaped roofs, consisting of support profiles which run together in a star shape at node points and are fastened to one another by means of circular blanks and form a multiplicity of irregular triangles and optionally quadrilaterals, two plate-shaped circular blanks being used at the nodes.
  • Dome-shaped roofs for covering round structures such as tanks, clarifiers, but also halls and the like, which can reach up to 100 m in diameter, are known.
  • the supporting structure or the framework consists of support elements that have a large number of irregular triangles, some of them. if necessary, also form quadrilaterals, and are connected to one another in a bending-resistant manner.
  • This framework supports the actual roof skin, e.g. made of sheet metal, which are attached to the brackets using special clamping strips. If necessary, such roofs can be equipped with accessories such as overpressure and vacuum membrane valves, ventilation hoods, manholes, sockets or catwalks, work platforms, etc.
  • the inventor has set itself the goal of providing a frame of the type mentioned at the outset which, while maintaining the same strength, enables a reduction in weight and can be produced more cost-effectively by the corresponding material savings.
  • a framework according to claim 1 leads to the achievement of the object according to the invention. It has proven to be advantageous to provide the hollow profiles used as supports with internal longitudinal stiffening ribs.
  • the dome-shaped roof structure 1 is composed by support profiles 2, which are connected at their ends to form circular joints 3 on round plates 4.
  • the profiles 2 form a multitude of irregular triangles underneath, whereby they can also determine square fields on the roof circumference.
  • six profiles 2 usually meet in a star shape at the nodes 3, and four or five profiles 2 also meet on the roof circumference.
  • a favorable cross section of the carrier profiles 2 is shown in FIG. 4: it is a hollow profile of a quadrangular cross section, the height of which is greater than the width.
  • the hollow profile 2 has on the inside on its side walls 6, 7 and on its lower sole 8 longitudinal stiffening ribs 9.
  • the thickness of the sole 8 is advantageously thicker than that of the side walls 6 and 7.
  • the upper wall 10 of the hollow support profile is expediently at least as thick as the sole 8.
  • This upper wall 10 has an outwardly directed longitudinal rib 11 on both sides of its center line Which ribs provide a support surface for the formwork sheets 12, and also between the ribs a longitudinal thickening 13 into which internal threads for bolts 14 can be cut.
  • a cover strip 15, which is fastened to the support profiles 2 with the screw bolts 14, is used to fix the formwork sheets 12. As is normally the case, the joint between the cover strip and sheet metal is sealed, for which purpose the cover strip 15 can be provided with sealing profiles 17.
  • an upper circular 4 and a lower circular 5 serve to connect the profiles 2 meeting at the node 3, at least one of them, here the lower round blank 4, has a hand hole 17.
  • the ends of the profiles 2 are chamfered laterally so that they can be brought far enough towards the center of the round plates 4, 5.
  • the resulting beveled surfaces 18, which also trim the inner stiffening ribs 9, are also visible in FIG. 3.
  • the ribs 11 and any protruding thickenings 13 are cut back on the upper wall 10 of the profiles 2, so that this wall 10 offers a flat contact surface for the upper circular blank 4.
  • bolts can then be pushed through holes made on the upper wall 10 and on the sole 8 of the profiles 2 and on the upper and lower round plates 4 and 5 for a provisional holding together.
  • locking ring bolts 19 are used for the definitive fastening instead of the provisional screw bolts and fastened from above or below.
  • the framework has high stability.
  • the upper circular blank 4 has recesses 22 on its edge, into which the ends of the ribs 11 can be inserted.
  • the projections 23 remaining between these recesses 22 are so long that the round diameter resulting there is approximately the same as that of the cover 20.
  • the thickness of the upper circular blank 4 is as large as the height of the support ribs 11, as a result of which the surfaces of the projections 23 and the ribs 11 are flush with one another and also form a flat contact surface for the narrow sides 24 of the shuttering surface 12 between the support profiles 2 .
  • the joint between the cover 20 and the supported edge of the sheet 12 can be sealed properly and permanently.
  • the upper round blank 4 also has a screw hole 25 which, of course before the cover 20 is attached, at selected nodes, e.g. can be used for the temporary fixing of eyebolts, on which suspension ropes of a rope sling can engage for the purpose of lifting and installing the finished cathedral roof on a building.
  • the edge 26 of the hand hole 17 is rounded in the direction of the upper round 3, as a reinforcement for the round and as a protective measure for the hand of the fitter.

Claims (6)

1. Ossature, en particulier pour toitures en dôme, constituée de profilés porteurs (2) qui concourent entre eux en forme d'étoile aux noeuds (3) et sont fixés l'un à l'autre et l'un à côté de l'autre au moyen de disques (4, 5) et forment une pluratité de triangles, et éventuellement de quadrilatères irréguliers, étant précisé qu'aux noeuds sont chaque fois employés deux disques (4, 5) en forme d'assiette, caractérisée en ce que comme profilés porteurs (2), on emploie des profilés creux à section sensiblement rectangulaire; et en ce qu'au moins l'un des disques (4, 5) présente en son centre un trou (17) pour la main par lequel on peut introduire des moyens de fixation (19), comme des rivets, des boulons à écrou chapeau, des tiges filetées, ou analogues, pour la fixation des extrémités des profilés (2) sur les disques (4 ou 5).
2. Ossature selon la revendication 1, caractérisée en ce que les profilés porteurs creux (2) présentent à l'intérieur, sur leurs parois latérales (6, 7) et/ou sur leurs semelles (8), des nervures de renfort (9) dirigées longitudinalement.
3. Ossature selon la revendication 1 ou 2, caractérisée en ce que les profilés porteurs (2) présentent, sur leur paroi supérieure (10) deux nervures en saillie (11) pour l'appui des tôles de revêtement (12).
4. Ossature selon la revendication 3, caractérisée en ce que les profilés porteurs présentent, sur leur paroi supérieure (10), entre les nervures en saillie (11), un renfort (13) pour l'usinage de taraudages pour des tiges filetées (14).
5. Ossature selon l'une des revendications 3 ou 4, caractérisée en ce que dans la zone des noeuds, les nervures (11) et les renforts éventuellement en saillie (13) sont rabotés; et en ce que de ce fait la paroi supérieure (10) des profilés (2) offrent une surface d'appui plane pour le disque supérieur (4).
6. Ossature selon l'une des revendications 1 à 5, caractérisée en ce que le disque supérieur présente des saillies (23) qui s'étendent entre les extrémités subsistantes des nervures (11), et dont la surface supérieure affleure avec celles des nervures (11) et forment avec celles-ci une surface d'appui plane pour les tôles (12).
