Definitions

  • the invention relates to a sub-roof for roofs covered with roofing panels.
  • a thermal insulation board is already known (DE-U 1 932 832), which is hung with an upper nose in a roof batten, a thermal insulation board already lying on the eaves side being somewhat covered in its upper area.
  • a cross bar for hanging the lugs on the roof tiles.
  • the crossbars are interrupted by water channels. Overlapping profiles are attached to the side edges of the thermal insulation boards in order to make the side joints watertight.
  • the thermal insulation boards come into an almost horizontal position, as a result of which water can be pushed back and the roof is no longer watertight.
  • Another disadvantage is the lack of windproofness, since the overlap in the transverse area is only slight.
  • thermal insulation panels for the construction of a sub-roof (DE-PS 23 49 710) these engage with their entire width, measured perpendicular to the eaves, between the roof battens and are supported with the eaves-side surface on the ridge-side surface of the lower roof battens from.
  • step folds are provided in the area of the transverse overlap, creating an essentially flat upper and lower surface of the lower roof.
  • a disadvantage of this construction is the easy vulnerability of the strongly profiled side edges and the associated consequence of a lower roof that is no longer watertight and no longer insulates at points of injury. With thicker thermal insulation panels, there is also the risk that they will tip out of the roof surface when laying or covering the roof tiles.
  • thermal insulation boards of different dimensions have to be used for different slat distances.
  • the lath spacing differs for different roof tile manufacturers and lies e.g. B. with a roof tile covering between about 32 cm to 36 cm. It is therefore necessary to manufacture slabs in this area, to keep them in stock, to take them into account when planning and to order, which is very time-consuming. Leftover remaining stocks of craftsmen and publishers are difficult to differentiate, keep in stock and thus reuse. Because of the complicated edge designs, waste or partially cut thermal insulation panels are hardly reusable, so that a relatively large amount of waste arises from waste.
  • Thermal insulation panels that are wider than the appropriate slat spacing should not be used. If, on the other hand, unsuitable thermal insulation boards with an undersize compared to the slat spacing are used, slits are created in the area of the overlap and thus weak points in the insulation.
  • the object of the invention is to design a sub-roof in such a way that the thermal insulation panels used for its construction have a particularly simple shape which is not very susceptible to damage and yet result in a reliable seal.
  • a sub-roof for roofs covered with roofing panels which consists of overlapping rectangular thermal insulation panels in the direction of the slope, each of which has a plane-parallel central part, which is followed by a wedge-shaped panel part on the first and eaves side.
  • the thickness of the wedge-shaped plate parts increases towards the center of the plate, the upper side of the ridge-side plate part lying in a plane with the upper side of the central plate part and the lower side of the eaves-side plate part lying in a plane with the underside of the central plate part.
  • the sum of the lengths of the middle and the eaves-side panel part - measured in the slope direction - corresponds at least to the length of the ridge-side panel part.
  • the ridge-side and eaves-side plate part each have a greater thickness at their edge facing the middle plate part than the middle plate part and there is a gradual transition.
  • the thermal insulation panels are also laid in such a way that they form an offset double or multiple cover.
  • any dimension can be selected as the width of the thermal insulation boards, which is suitable in terms of production technology and assembly technology and is advantageous.
  • the plate length depends on how many attachment points or support points, e.g. Slats to be bridged with a thermal insulation board; how many overlay layers are desired; how large the total thermal insulation layer thickness is desired; etc.
  • the object of the invention is to design a sub-roof in such a way that the thermal insulation panels used for its construction have a particularly simple shape which is not very susceptible to damage and yet result in a reliable seal.
  • a sub-roof for roofs covered with roofing panels which consists of overlapping rectangular thermal insulation panels in the direction of the slope, each of which has a plane-parallel central part, which is followed by a wedge-shaped panel part on the first and eaves side.
  • the thickness of the wedge-shaped plate parts increases towards the center of the plate, the upper side of the ridge-side plate part lying in a plane with the upper side of the central plate part and the lower side of the eaves-side plate part lying in a plane with the underside of the central plate part.
  • the sum of the lengths of the middle and the eaves-side panel part - measured in the slope direction - corresponds at least to the length of the ridge-side panel part.
  • the ridge-side and the eave-side plate part each have at least the thickness of the middle plate part on its edge facing the middle plate part, with larger thicknesses there is a step-like transition.
  • the thermal insulation panels are also laid in such a way that they form an offset double or multiple cover.
  • any dimension can be selected as the width of the thermal insulation boards, which is suitable in terms of production technology and assembly technology and is advantageous.
  • the plate length depends on how many attachment points or support points, e.g. B. slats to be bridged with a thermal insulation board; how many overlay layers are desired; how large the total thermal insulation layer thickness is desired; etc.
  • the watertightness of an under-roof constructed with thermal insulation panels according to the invention is achieved on the one hand by the at least double covering of the thermal insulation panels and on the other hand by an offset laying of the side joints. Due to the very long and wide coverings, extensive windproofness is also guaranteed.
  • thermal insulation panel Since the middle plate part of the thermal insulation panel is always covered when laying the next thermal insulation panel above it, simple fastening means, e.g. B. a wide-headed nail, the thermal insulation panel can be attached safely without a cold bridge or risk of corrosion. This also gives you the option of building a provisional, watertight roof only with thermal insulation panels, even before roofing panels, e.g. B. roof tiles are covered.
  • Complicated and easily vulnerable side rebate designs for the water supply are not necessary due to the offset and overlapping overlap of the thermal insulation panels.
  • a panel formation with a smooth underside of the ridge-side panel part can be applied directly to formwork and, with the appropriate width, to rafters, etc.
  • the thermal insulation panels can also be used as wall cladding panels. If the top of the eaves-side panel part is smooth, slate or asbestos panels, cardboard, sheet metal, etc. can be laid on the overall smooth surface of the sub-roof.
  • the ridge-side and eaves-side panel part of the thermal insulation panel is of identical design with regard to its cross section and is arranged point-symmetrically to the panel center.
  • this thermal insulation board has no special inside or outside and can therefore be easily manufactured as well as simply stacked, packaged and laid.
  • a particularly preferred embodiment is claimed in claim 4, in which the underside of the thermal insulation panel is designed for hanging on a roof batten and the upper side of the thermal insulation panel is designed for hanging roof covering panels.
  • a universally applicable thermal insulation panel is achieved which is suitable for all possible simply overlapping roof tiles, such as roof tiles, interlocking tiles, etc. with different lath spacing and additionally for a beaver tail covering.
  • the drainage grooves claimed in claim 6 ensure that no water remains in the wedge steps.
  • the drainage grooves are used to ventilate the roof covering slabs.
  • the drainage grooves should widen at their eaves-side end, which results in a nozzle-like effect and acceleration of an air flow for the roof ventilation.
  • a longitudinal section of a thermal insulation board 1 is shown in side view.
  • the basic Z shape can be seen as it is again shown in abstract form in FIG. 4.
  • the thermal insulation panel 1 consists of a panel part 2 on the ridge side (with reference to the already covered side view of FIG. 6), a central panel part 3 and a plate part 4 on the eaves side.
  • the ridge-side plate part 2 is wedge-shaped with an underside 5 and an upper side 6.
  • the eaves-side plate part 4 is also wedge-shaped with an upper side 7 and an underside 8.
  • the middle plate part 3 contains an upper side 9 and an underside 10 lying parallel thereto.
  • the upper side 9 is an extension of the top 6 and the bottom 10 is an extension of the bottom 8.
  • steps 11 and 12 are formed both on the underside 5 and on the upper side 7 in the area of the step-shaped wedge attachment.
  • the elevation of the crosspiece is not included in the stylized form of FIG. 4.
  • steps 11, 12 can be shaped as attached ribs or, as shown in FIG. 1, as raised portions that curve into sides 5 and 7.
  • the second embodiment according to FIG. 2 corresponds to the embodiment according to FIG. 1 both in the basic shape and in the shape of the plate part 2 and the middle plate part 3 on the deadline. Only on the top side 7 is there a step 12 in the middle area of the top side 7 Bar 13 formed.
  • FIG. 3 shows a top view of the thermal insulation board 1 corresponding to FIG. 1.
  • the three areas of first-side plate part 2, middle plate part 3 and eave-side plate part 4 can again be seen, the arrow being intended to indicate the direction of incline 14 in the case of a covered plate.
  • drainage grooves 15, 16 lead in the downward direction 14. Only two drainage grooves 15, 16 are shown here, but there may be more, if necessary, so that the Steps 12, 13 can also be shown as bumps lying in the transverse direction.
  • the drainage groove 15 has just been carried out, while the drainage groove 16 shows a second embodiment with a lower, nozzle-like widening 17 for accelerating an air flow for the roof ventilation.
  • the lateral edges 18, 19 of the thermal insulation board 1 are offset, an upper side area 20 on the right in plan view being offset to the left relative to a lower right side area 21, so that oblique projections 22, 23 result. From Fig. 3 it can be seen that the projection 23 lies slightly further down to the eaves side than the projection 22. When a second plate engages with its projection 23 in the projection 22 of the plate shown and through the roof covering a train on the second When the plate is exerted, the two projections press tightly together.
  • FIG. 5 shows four rows 24, 25, 26, 27 of thermal insulation panels 1 on a substructure made of roof battens 28 (the thermal insulation panels are shown without lateral projections 22, 23). It is be already recognizable from this representation that the ridge-side plate part 2 and the eaves-side plate part 4 are somewhat longer than the roof lath distance 29 and the middle plate part 3 measures about half of the roof lath distance 29, so that overall a wide coverage of both immediately below a thermal insulation board Thermal insulation board as well as the thermal insulation board located underneath with about half of the eaves-side panel part.
  • FIG. 6, shows a section along the line BB from FIG. 5, although roof covering slats 30 are already covered on the rows of thermal insulation boards 24 to 27.
  • the sub-roof is covered row by row from below, the individual thermal insulation panels with fasteners, e.g. B. wide-headed nails 32 can be storm-proof and nailed if necessary.
  • the attachment is advantageous approximately in the middle of the panel, so that the thermal insulation panels are not raised even in strong wind and break out.
  • the fastenings 32 are also covered again by the next row of plates to avoid cold bridges and corrosion damage.
  • thermal insulation panel 25 In the row of thermal insulation panels 25 (FIG. 6), a thermal insulation panel with a strip 13 is shown.
  • thermal insulation panels of the second embodiment according to FIG. 2 it can be seen that a double beaver tail roof covering is possible.
  • the relatively simple shaped thermal insulation panel can be used to produce a waterproof sub-roof, which is suitable for both flat and steep roofs with different distances between the battens.
