Definitions

  • the invention relates to a composite profile of pipes connected by bolts of weldable material with an intermediate fire and temperature-resistant insulating layer for frames of wall elements, doors and windows, in which the bolts penetrating the insulating layer are fixed to the pipe wall facing the insulating layer and the thickness the insulating layer corresponds to the bolt length.
  • a composite profile of this type is known (DE-A-33 24 210), in which the tubes are designed as metal tubes and are made of weldable material. These pipes are connected to each other by metal webs made of weldable material, which are welded at both ends to the pipe wall facing the insulating layer.
  • the metal pipes and also the metal webs are provided with a surface protection layer, since it is necessary due to the approval conditions that the surfaces of the metal pipes are permanently protected against corrosion.
  • a galvanizing layer is provided as the surface layer for steel pipes. The galvanization of the steel pipe surface affects the quality of the weld between the metal pipes and the metal webs. Outgassing or liquefying the zinc results in blowholes in the weld.
  • the impulse currents required for the welding can lose their effectiveness via shunts due to the already welded metal webs.
  • only metal pipes made of weldable material can be used in the production of the known composite profile.
  • a frame component which consists of three tubular profiles, an elastic sealing strip being arranged between the outer profiles and the inner profile.
  • the outer profiles are connected by bolts that extend through the inner chamber of the inner profile.
  • Each bolt is formed in two parts, the bolt parts being welded in the inner chamber of the inner profile.
  • the invention has for its object to design a composite profile of the type mentioned so that the quality of the weld in the bolt area is improved.
  • each bolt is formed in two parts, the dividing surface runs at an angle to the longitudinal axis of the bolt, is free of a surface protective layer, the bolt parts have been welded to one another after the insulating layer has been put on, and the insulating layer has been cut out from a lateral boundary surface to the dividing surface is, wherein the recess is cylindrical or designed as a counterbore.
  • the stud shell can be provided with a surface protection layer.
  • the surface protective layer can be omitted for bolts with a relatively large diameter.
  • the insulating layer has a recess extending from a lateral boundary surface and extending to the bolt dividing surface. This makes it possible to move the bolt parts in the area of the dividing surfaces without being impeded by the insulating layer.
  • This recess can be cylindrical or countersunk.
  • the bolt parts can be screwed to the pipes of the composite profile.
  • the tubes can thus be made of any material, e.g. be made of stainless steel, aluminum, plastic or composite materials.
  • Fig. 1 a two-leaf protective door against fire and smoke is shown, the wings 1 and 2 are equipped with double glazing 3.
  • the casement frames are formed by hollow sections 4. 5 made of steel, between which a fire and temperature resistant insulating layer 6 is arranged.
  • the hollow profiles 4, 5 are connected to one another by bolts 7 which extend through bores in the insulating layer 6 and are fixed at the ends to the walls of the hollow profiles 4, 5 which are adjacent to the insulating layer 6.
  • the hollow profiles 4.5 made of steel sheets are covered on the outside by profile rails 8.9 made of aluminum.
  • the composite profile 10 has rectangular tubes 12 and 13, between which a fire and temperature-resistant insulating layer 14 is arranged.
  • This insulating layer is made of bolts 15 penetrated from weldable material.
  • Each bolt 15 is formed in two parts and consists of the bolt parts 16 and 17, which have a threaded pin 18 and 19 on the side facing the tube 12 and the tube 13, respectively. These threaded pins are screwed into a threaded bore in the tube wall 20 or 21, which lies adjacent to the insulating layer 14.
  • Fig. 1 the bolt parts 16, 17 have a different length.
  • the dividing surface 22 between the bolt parts 16 and 17 runs at right angles to the longitudinal axis 23 of the bolt.
  • the course of the dividing surface 22 to the longitudinal axis 23 of the bolt can also take place at an angle which deviates from the right angle.
  • the bolt parts 16 and 17 have no surface protective layers in the division area.
  • the end faces of the bolt parts that collide in the dividing surface are formed as bare surfaces, so that when the bolt parts 16 and 17 are welded, a high welding quality results.
  • the welding is carried out by a flash butt welding process or by a pulse welding process.
  • the bolt parts 16 and 17 are first screwed to the walls 20 and 21 of the tubes 12 and 13.
  • the insulating layer 4 is placed over the bolt parts 17, which are arranged like the bolt parts 16 over the length of the tubes 12 and 13. Then the bolt parts 16 and 17 are welded together.
  • the bolt parts 16 and 17 are dimensioned in terms of their length between the tubes 12 and 13 so that they come to rest within the distance formed by the insulating layer 14 and have a welding allowance in this contact area, which when used flash butt welding or pulse welding for a clean full-surface connection of the bolt parts ensures and the insulating layer 14 clamped largely free of play between the tubes 12 and 13.
  • the end faces of the bolt parts 16 and 17, which are welded to one another, can additionally be equipped with ring cutting edges or cams for targeted welding.
  • the insulating layer 14 is provided with cutouts 24 which extend as far as or slightly beyond the dividing surface 22.
  • these cutouts are designed as cylindrical cutouts 24.
  • the cutouts have the shape of a counterbore 15.
  • the bolt part 16 which is positioned and fixed on the tube 12, has such a height that it is located within the recess 24 of the insulating layer 14 and is thus able to compensate for larger misalignments with the bolt part 17 without problems.
  • the bolt parts 27 are screwed to the inner wall 28 of the tube 29, specifically via a threaded pin 30 which is screwed into threaded holes in the inner wall 28 or which is equipped with a cutting thread.
  • the bolt part 31 is welded to the tube 32.
  • the dividing surface 22 between the bolt parts 27 and 31, on which the bolt parts are welded, is also adjacent to the tube 29, as in the embodiment according to FIG. 3.
  • the bolts 33 are formed by bolt parts 34, 35 which are welded to the associated inner wall 36, 37 of the tubes 38, 39.
  • the bolt parts 34, 35 are welded to one another in the dividing surface 22 and penetrate as in the other composite profiles 2, 3 and 4, an insulating layer 40.
  • the bolt parts 41, 42 have conical projections 43, 44 which engage in conical bores in the inner walls 45 and 46 or extend through these bores into the interior of the tubes 47, 48. Both the surface of the conical projections 43, 44 and the bore surfaces in the inner walls 45, 46 are free of a surface protective layer (zinc), so that welding with high quality can be carried out between the projections 43, 44 and the inner walls 45, 46 .
  • a surface protective layer zinc
  • FIG. 7 shows a welding device which is inserted into the hollow chamber of the tubes 12 and 13, with which the bolt parts 16, 17 are welded in the region of the dividing surface 22.
  • the fastening means of the bolt parts 16, 17, which are designed as threaded pins 18, 19, extend into the hollow chambers of the tubes 12, 13.
  • a welding process can be used in which the contact is not made via the metal pipes 12, 13 from the outside, but is made directly on the bolt parts 16, 17.
  • one or both electrodes are inserted into the hollow chamber and fixed to the respective fastening means in the tube by means of corresponding clock feeds. After the welding process has been completed, the pipe is cycled further and the welding process is carried out in the same way on the next fastening means of the bolt part.
  • the contact units 49 and 50 or the contact units 49 and 50 are inserted into the hollow chambers of the tubes 12 and 13 and each consist of the electrically conductive contact 51 and 52 and a clamping unit 53 and 54, which simultaneously isolate the electrodes make the pipes 12, 13.
  • the complete unit 49 or 50 or 49 and 50 is clamped in the hollow chamber. After the welding pulse, the unit is released and the composite profile clocked to the next bolt.
  • the welding can of course also be carried out from the outside.
  • a composite profile is shown, in which the bolt parts 55, 56 are fixed on the associated inner wall 58 or 59 of the tube 60 or 61 via a pop-in rivet (pop rivet) 57.
