Definitions

  • the present invention pertains to a double-layer sheet-metal roof in accordance with the preamble of patent claim 1 as well as to a roll felt for use in a double-layer sheet-metal roof.
  • Sheet-metal roofs in double-layer construction are used for reason of their comparatively simple and quick assembly as well as manufacture, and namely in rafter or purlin construction being thermally insulated in that insulation material, roll felts made from mineral wool in particular, is inserted between the two layers of the sheet-metal construction.
  • Sheet-metal roofs of this kind mostly are constructed of sheet-metal profile supports which are fixed to support girders and carry a sealing layer located thereabove, the insulation material and the sheet-metal profile layer as upper layer (see for example FR-A-26 14054). Spacer profiles are provided between sheet-metal profile support and sheet-metal profile cover layer, in order to limit the gap between the two layers, in which the insulation material is accommodated.
  • a construction considerably free of thermal bridges, of the insulation materials located on the roof is guaranteed in that by means of suitable flange formations on spacer profiles a knife-like or claw-like engagement connection with the insulation material is effected by the flange formations directly engaging with the material of the roll felts used preferably.
  • the roll felts need not be prepared. Rather is the engagement into the soft insulation material effected by displacement of the latter, wherein in a preferred embodiment it is, however, meaningful to provide for a cut without removal of material in order to permit controlled engagement of the flange formations acting as claw.
  • spacer members which may be selectively provided over the length of the spacer profiles and/or web flanges, respectively, and which extend between web flange and sheet-metal profile cover layer and also are screwed on both sides.
  • These spacer members preferably are made from a material having low thermal conductivity, from synthetic material in particular. Because of the different heights of the spacer members, the degree of compression of the insulation materials between the two layers of the sheet metal can be adjusted. Depending on the kind o fuse, it can be meaningful to make the roll felt multilayered, in particular with different solidity per layer, adjustment of solidity advantageously being effected using the bulking density of the corresponding layer.
  • the distance between sheet-metal profile cover layer and sheet-metal profile support is defined by special screws having a threaded front section with a subsequent thread-free section of greater thickness, having a stop determining the distance as well as behind this further threaded section wiht larger subsequent thread than the threaded front section, serving as abutment for the sheet metal profile layer.
  • Fig. 1 serves for elucidation of the general construction of a double-layer sheet-metal roof in the manner of a roof of sheets with trapezoidal corrugations, referred to as purlin roof.
  • Said roofs consists of sheet-metal profile supports 2 disposed on double T profile girders 1 and preferably screwed therewith or welded thereto, said supports being formed by sheets having spaced trapezoidal reinforcement beads.
  • the upper end of the sheet-metal roof is formed by the sheet-metal profile cover layers 5 which in analogy with the sheet-metal profile cover 2 are provided as sheets having spaced beads here of trapezoidal shape, below which - if applicable - a further sealing layer 6 can be disposed. Furthermore, said sheet-metal profile cover layer 5 usually is supported with respect to the sheet-metal profile support 2 using Z-shaped spacer profiles 7. Said spacer profiles 7 are screwed to the sheet-metal profile support 2 or the sheet-metal profile cover layer 5, respectively, using their Z flanges.
  • the insulation material 4 for which mainly roll felts are used fills the space between said cover layer 5 and said support 2 and is chambered in cassette-like manner between adjacent spacer profiles 7', of which on the left-hand side only a traditional Z profile is shown.
  • a spacer profile of this kind forms a heat and/or cold bridge, respectively, between said sheet-metal profile cover layer and said sheet-metal profile support, this causing worsening of the over-all thermal insulation value of the roof.
  • Fig. 1 and that of Fig. 2 show a double-layer roof of sheets with trapezoidal corrugation, improved in accordance with the present invention, in non-aerated construction and in rafter construction.
  • the spacer profiles 7 also are made Z-shaped and are fastened with respect to the sheet-metal profile support 2 by screwing of their lower web flange 9.
  • the further web flange 12 protrudes in parallel alignment with the sheet-metal profile support 2 and the sheet-metal profile cover layer 5.
  • Said web flange 12 also disposed with a distance below the sheet-metal profile cover layer 5, in the manner of a knife or claw directly engages with the material of the roll felt 4, starting from its lateral surface 13, the roll felt thereby being solidly fixed between adjacent spacer profiles 7.
  • the insulation material or the roll felt 4, respectively has excess thickness with respect to the height of the spacer profile 7 such that above said spacer profile 7 still insulation material of roll felt 4 is located, which on top reaches above said web flange 12.
  • no heat or cold bridge, respectively will be given between the sheet-metal profile cover layer 5 and the sheet-metal profile support 2.
  • the cut is badly visible, it is sensible for assembly purposes to mark the material-internal end of the cut form the outside with a marking.
  • the embodiment under Fig. 1 for the sake of elucidation shows a roll felt with uniform material density and solidity, however, also insulation materials, roll felts in particular, having different solidities can be used, the different solidities preferably being effected using differently adjusted bulking densities in corresponding layers of the insulation material.
  • the area of the insulation material protruding over said web flanges 12 and/or being adjacent thereto is built with increased bulking density and thus increased solidity, whereby the area of increased solidity - if applicable - quasi can serve as spacer between the web flange 12 and the sheet-metal profile cover layer 5.
  • a spacer member 14 which preferably is made from a material with low thermal conductivity, synthetic material in particular.
  • a spacer member is shown in enlarged view in Fig. 2 and has a stud or screw sleeve 10 with laterally protruding abutments 16 by which the sheet-metal profile cover layer 5 is supported, the spacer member 14 being screwed with the web flange 12 and the sheet-metal profile cover layer 5.
  • the roll felt 4 In the sense of action control it is advantageous to provide the roll felt 4 with a cut 15 in the area of the engagement of the flange 12, however, without removing material in doing so.
  • This cut preferably is produced using a rotating knife and in its depth is adapted to the width of the flange 12, wherein the upper side of the roll felt can be particularly marked (e.g. print/markings) in the area of the cut (also in case of different solidity).
  • Fig. 3 shows a partial section of the sheet-metal roof in purely schematical representation, wherein the spacer member is formed by a screw 17.
  • Said screw 17 herein keeps the sheet-metal profile cover layer 5 at a given distance to the web flange 12 of the spacer profile 7. Further particulars of the special screw 17 herein result from Figs. 4 and 5.
  • the screw has a threaded front section 17a which is followed by a thread-free section 17b of greater thickness, which forms a stop shoulder 17c. Between the thread-free section 17b and the screw head 17d provided with a washer 17e, a further threaded section 17f of larger thread thickness than the threaded front section 17a is located.
  • the washer 17e advantageously is captively provided with sealing material. Sealing may also be performed by a separate sealing or washer ring by which a metal to metal contact is avoided.
  • the screw is a self-tapping screw so that no opening must be bored.
  • the sheet-metal profile cover layer 5 is screwed to the web flange 12 using the screw 17.
  • the threaded front section 17a is screwed into the web flange 12, namely up to the stop 17c, wherein at the same time due to the further threaded section 17f the sheet-metal profile cover layer 5 is fixed to a given distance which is determined by the axial distance of the stop 17c to the washer 17e.
  • the threaded front section is made longer than the thick threaded section 17f, namely preferably with 1.5 to 2 times the length, the section 17b thickened with respect to the threaded front section 17a having about half the length of the thicker threaded section 17f.
  • the head of the screw 17d is embodied as cap bolt, however, also any other screw head is conceivable, e.g. hexagon socket or the like.
