Definitions

  • the invention relates to a sealing profile according to the preamble of patent claim 1.
  • panel-shaped facade elements e.g. made of glass
  • a load-bearing facade substructure or supporting structure which can be designed, for example, as a post and beam construction made of heavy metal profiles.
  • the vertical loads of the facade elements are transferred to the facade substructure via supporting elements that are welded or screwed to the facade substructure.
  • WO 99/58781 A1 discloses a facade construction with a post and beam support structure made of T-shaped Metal profiles, in which block-like supporting elements are fastened with fastening screws to fastening profile rails, which in turn are fastened to the transom profiles of the facade construction.
  • the fastening screws are fastened in grooves of the fastening profile rails which are open to the outside. In doing so, they pass through a seal which covers the mounting profile rail and on which the support elements rest.
  • the fastening situation shown here has the disadvantage that the rigidity of the connection of the support elements is relatively low and the load-bearing elements incline significantly downwards even with a relatively low load-bearing capacity, or only small load-bearing capacities can be realized for each load-bearing element if the inclinations are kept to an acceptable level.
  • DE 196 06 906 A1 discloses a facade construction with a mullion-transom supporting structure made of hollow metal profiles, in which cross-shaped supporting elements are screwed to the profiles with fastening screws in the crossing area of the mullion and transom profiles.
  • the fastening screws penetrate seals arranged on the profiles, against which the support elements rest.
  • the invention relates to a sealing profile for forming a seal in a support structure for facade elements as described below, in which the support elements or at least some of the support elements are formed by a large number of support bodies provided in the seal.
  • the supporting structure for facade elements comprises a supporting bar made of a metal profile material and a supporting element for a facade element protruding from the supporting bar in the horizontal direction.
  • the supporting element is fastened to a fastening profile section of the supporting bolt which extends essentially vertically when viewed in cross section.
  • a seal extends over the entire adjoining area formed between the fastening profile section of the support bar and the support element, which seal prevents water from entering this area.
  • the support element is supported at several points via support elements (first support elements according to the claims) on the fastening profile section of the support bar, which are arranged inside the seal or penetrate the seal from the outside or penetrate it.
  • the support element is practically not supported on the seal in the lower area of its adjoining area (apart from its sealing adjoining to the seal), but directly on the fastening profile section of the support bar or on a very thin area of sealing material, which leads to a high Stiffness of the connection of the support elements to the support bar against tilting in the load direction leads so that the support elements practically do not tend down under normal loads or per support element when adhering to reasonable Inclinations very large loads can be realized.
  • the sealing profile according to the invention comprises a profile area in which, viewed in the longitudinal direction of the sealing profile, preferably identical supporting elements are embedded in the sealing material at a regular spacing or one behind the other according to a regularly recurring spacing pattern, preferably in the form of steel balls or steel pins.
  • the support elements are preferably arranged in two rows spaced apart from one another.
  • the figures 1 and 2 show vertical sections through part of a building glass facade created in post and beam construction in the area of a supporting beam 1, 20 of the supporting structure 2 of the building facade.
  • the incision runs at 1 by one of the supporting elements 22, of which the glass facade elements 4 are supported, and at 2 between two supporting elements 22 fastened to the supporting bolt 1, 20 shown.
  • the supporting bolts 1, 20 of the supporting structure 2 are each formed from a supporting profile 20 made of a rectangular steel tube and a fastening profile rail 1 made of a rolled steel profile fastened thereto.
  • the fastening profile rail 1 is fastened by welding at regular intervals on a flat vertical fastening surface 6 of the supporting profile 20.
  • the support elements 22 are made of solid aluminum profile material.
  • a sheet metal strip 30 made of stainless steel is arranged on its side facing the mounting profile rail 1, which is provided with a plurality of embossings 31 along its lower boundary, which protrude as cone-shaped projections 25 on the side of the sheet metal strip 30 facing the mounting profile rail 1. They are each fastened to the respective fastening profile rail 1 by means of four fastening screws 11 .
  • the facade elements 4 are mounted on the support elements 22 by means of spacer plates 28 and are secured to the support structure 2 by retaining profile rails 3 , which are also fastened to the fastening profile rails 1 by means of fastening screws 11 .
  • 3 seals 21, 29 are arranged between the facade elements 4 and the fastening profile rails 1 and between the facade elements 4 and the holding profile rails.
  • the retaining profile rails 3 press the facade elements 4 under a compressive force generated by the fastening screws 11 against the seals 21, 29, with elastic deformation of the same.
  • the seals 21 on the facade between the facade elements 4 and the mounting profile rails 1 each extend over the entire mounting profile rail 1, and thus not only over the respective adjoining areas formed between the support elements 22 and the mounting profile rails 1, but also over areas above and below the respective Supporting element 22 are.
