Definitions

  • the invention relates to a flame-retardant surface element for shipbuilding, in particular a ceiling or wall element for ships or artificial islands for offshore extraction technology, with a metal core and fire protection mats or the like fixed to it by pins or the like.
  • Shipbuilding walls are generally the supporting structures of the ship. They consist of sheets with regular stiffeners that are welded on or designed as beads. All exterior walls are insulated against heat and cold in shipbuilding.
  • a ship's wall on the market consists of a steel plate with welded-on L-profiles as stiffeners. Both the L-shaped profiles and the steel plate itself are covered with fire protection mats, for example the ISOVER brand; the fire protection mats are held by thin fastening pins.
  • the mineral wool applied in this way must then be provided with tarpaulins, decorative walls or the like. Protective surfaces. The entire structure with its easily damaged outside has proven to be disadvantageous. In addition, the mounting pins form undesirable thermal bridges.
  • the inventor has set himself the goal of designing a flame-retardant surface element of the type mentioned at the outset in such a way that the latter forms a compact, yet very light component which lacks the disadvantageous thermal bridges.
  • the metal core is formed by at least one light metal profile which has recesses on a profile plate at a distance from one another as openings of chambers in the form of undercut grooves, and at least one other undercut chamber opening towards the opposite side near each chamber.
  • several light metal profiles should be arranged so that the profile plates are aligned with one another and their chambers run parallel to one another.
  • Dowel profiles made of flame-retardant material are inserted into the chambers and serve as anchors for fire protection panels running on both sides of the profile panel. These can be connected to the dowel profiles by metal pins, nails or screws without thermal bridges being able to form here.
  • the surface elements according to the invention are considerably lighter than the surface elements according to the prior art. They can also be assembled very quickly, which leads to a reduction in labor costs. Another advantage is that smooth and flat outer surfaces are created when the fire protection panels are applied.
  • Such surface elements can easily be used for structures and residential modules of drilling rigs, but also for ship installations. Especially with Bohr islands, the safety regulations are very strict. For example, a wall with an outside temperature of 1150 ° C must take over the full static load for one hour and must not measure more than 140 ° C at the metal core on the side facing away from the fire. However, since there can also be fire on the inside of the rooms, 970 ° C in the opposite direction applies for 60 minutes.
  • the surface element according to the invention meets these requirements and also offers the advantages already described.
  • the metal core or the light metal profile is provided with two oppositely opening chambers, which are adjacent to one another and are delimited by three webs molded onto the profile plate, two of which at their end remote from the profile plate by means of alignments which are aligned with one another offer an L-shaped cross section.
  • the result is an extremely stable metal core, which fixes the distance between the fire protection plates and can also be easily manufactured as a light metal extruded profile. Further refinements of the light metal profile are described in the subclaims and have in common that insertion tracks are created for flame-retardant dowel profiles which are accessible from both profile sides and can accommodate nails, screws or corresponding connecting elements without this resulting in temperature bridges.
  • the inserted dowel profile is at a distance from the rear wall of the chamber, so that the free ends of the nails or screws end in a cavity and do not touch the light metal core.
  • the same effect is provided by the requirement to provide a channel in the rear wall of the chamber.
  • the width of the surface element according to the invention can be varied by inserting a web between a channel profile forming the chamber and the profile plate, the length of which can be selected.
  • An inner wall 10 shown in FIG. 1 of a ship or an oil rig (not shown further) has fire-retardant wall panels 12 with a thickness e of 12 on both sides of a core made of light metal profiles 11 - a respective cross-sectional length a of here 600 mm and a cross-sectional width b of 45 mm mm made of fiber silicate or the like material with a weight of about 10.5 kg per square meter of square.
  • a joint between two wall plates 15 can be seen at 14, which makes the use of a pair of screws 31 necessary.
  • a weld seam between a channel edge 36 of a light metal profile 11 and the chamfered longitudinal edge 37 of the abutting light metal profile 11 can be seen.
  • Non-combustible mineral wool mats 40 are inserted into the wall cavities remaining after insertion of the dowel profiles 30.
  • the slot 16 of the profile plate 15 adjacent webs 17 a, 18 a cross-sectionally mutually stepped and form two abutment shoulders 42, and a rear wall offset therefrom. 43; also here is the cross-sectional central axis M1 or M2 axis of symmetry of the chamber cross-section.
  • Chamber 25a - adjacent chamber 26 a is of a T-shaped extension portion 45 of the web 18 a on the one hand as well as a lateral conformation 46 on the web 18 a limited; this projection 46 forms beyond the axis of symmetry M2 the other wall 26 a , the rear wall 43 a of the profile plate 15 is at a distance t of 16 mm.
  • the head part 47 of the T-like extension section 45 forms an abutment surface with an aligned part 48 of the projection 46 at a distance from the profile plate 15 corresponding to the profile width b.
  • the distances s1 and s2 of the profile ends 36 and 37 from the nearest central axes M2 and M1 are not the same, namely about 50 mm and 110 mm.
  • the light metal profile 11 consists of a cross section of a profile plate 15 with - here three - longitudinal slots 16 of width i (for example 30 mm) and on both sides of that longitudinal slot 16 webs 17, 18 formed at right angles, which, by determining that cross-sectional width b, have a parallel to the profile plate 15 extending transverse wall 20 are connected.
  • the latter protrudes beyond one web 18 and is aligned with one leg 22 of a third web 19; Leg 22 and the free edge 21 of the transverse wall 20 in turn limit a slot 23 of width i.
  • the widths of the slots 16 and 23 are dimensioned the same here, but can also differ.
  • the webs 17 to 19 delimit two adjacent chambers 25, 26 with mutually opposite access openings in the form of the slots 16 and 23.
  • the distance h between the cross-sectional central axes M 1 and M 2 of adjacent chambers 25, 26 measures 56 mm
  • the distance f between the cross-sectional central axes M 1 and M2 rectified chambers 25 and 26 measures 200 mm.
  • the clear chamber width m is about 52 mm
  • q 1 for example 6 mm
  • the cross section of the one chamber 25 b at the slot 16 of the profile plate 15 in FIG. 5 corresponds approximately to the chamber 25 a of FIG. 4, the chamber rear wall 43 e here being a semicircular cross section.
  • the distance h 1 between the cross-sectional central axes M 1 and M 2 is so large - here: 100 mm - that the oppositely opening chamber 26 b cannot be formed by boundary walls of the other chamber 25 b ; rather, a channel profile 50 is provided here as a chamber boundary, which is formed on the inner surface of the profile plate 15 by a stem 51 falling into the central cross-sectional axis M2.
  • the contour of the chamber 26 b corresponds to that of the chamber 25 b , here also molded parts 47, 48 are aligned with one another and delimit the slot 23.
  • the profile width b here is 70 mm with different thicknesses e and e 1 of the wall panels 12.
  • the chamber 26 b receives a plate-like clamping piece 53 parallelogram-like outline, the width c of which is less than the width i of the slot 23 and which, thanks to this provision, can be inserted into the chamber 26 b and rotated therein until the end position shown in FIG. 7 is reached, in which a screw 54 can be tightened to fix a steel connection 60 to the light metal profile 11 b .
