Definitions

  • the invention relates to thermal insulation boards which can be laid over rafters, which have a step-fold-like ridge-side edge overlapping support strips in the covering of the ridge-side neighboring plate, on their step-fold-like eaves-side edge a cover strip overlapping the support strip of the eave-side neighboring plate and a side fold part or one on their side edges has complementary cover fold part to form a side fold and with water channels running in the ridge direction.
  • Such a thermal insulation board is known from DE-A-2 519 459 and bears on the upper side a plurality of water guiding channels which run in the first eaves direction and which are intended to discharge the water accumulated on the surface of the thermal insulation element. If, in the case of a saddle roof, the individual elements are laid next to one another in the usual way starting at the verge, the result is that the side folds between the individual elements from the ridge to the eaves run one behind the other. This results in areas in the intersection of the vertical side folds in the projection and the horizontal folds that do not ensure reliable water flow, so that in particular when larger amounts of water penetrate, this can also penetrate into the under-roof area.
  • the invention has for its object to provide measures with which an absolutely safe water flow is guaranteed even when larger amounts of water penetrate from the side interlocking to the water guide channels on the top of the thermal insulation panels.
  • This object is achieved in that the lateral edges of the thermal insulation boards with their side and top fold parts run obliquely to the vertical ridge direction.
  • the measures of the invention advantageously achieve that even when laying the individual thermal insulation boards at the same distance z. B. from the verge the side folds of the ridge-side elements of a row no longer encounter the side folds of the elements installed on the eaves side, but rather are offset against them. This results in a better water flow, since the watercourse is displaced laterally from the row of plates to the row of plates below on the eaves side and towards the middle of the plate and can be further drained off via the water channels in the ridge direction.
  • a further embodiment of the invention provides that the support strip formed on the ridge-side panel edge is provided with a groove arranged transversely to the roof pitch, the lowest point of which opens into a water-guiding channel aligned in the roof pitch, which runs to the top of the eave-side roof strip.
  • This known configuration of the transverse gutter has the further effect that the side rebate next to the eaves side is further relieved by the displacement of the watercourse towards the middle of the insulation panel, since any water that has penetrated runs to the lowest point in the central region of the thermal insulation panel and the transverse gutter of the vertical water duct runs and so that it is kept away from the next side fold.
  • a further improvement in the water flow results from the fact that the side folds rise from a level in or below the top of the ridge-side support strip to a level that is higher than the underside of the cover strip. This ensures safe water flow to the top of the thermal insulation, even with very narrow, horizontal support strips and cover strips.
  • thermal insulation panels 10 which are arranged one above the other in pairs.
  • the lateral edges 11 of the individual thermal insulation boards are designed to run obliquely to the vertical, so that after laying the boards a correspondingly slanted lateral joint is created.
  • the individual thermal insulation panels have on their ridge-side edge a support strip 12 which overlaps in the covering of the ridge-side neighboring panel and over which a cover strip 13 attached to the respective eaves-side edge overlaps.
  • the sloping side edge has the effect that when the individual thermal insulation boards are laid one above the other, the butt joint does not merge directly into one another at the side edge, but is offset with respect to the next laying row. If with the thermal insulation boards z. B.
  • the element adjacent to the verge can be trimmed along the grooves 15 in the surface, so that the elements rest with the vertically extending end face at the verge. 1 that in such a case the lateral joints of the insulation boards laid one above the other are always offset from one another.
  • the individual thermal insulation panels 10 are provided on the upper side with a water guide channel 17, which runs from a level below the surface of the support strip 12 to a level above the lower surface of the cover strip 13.
  • a collecting channel 18 runs along the eaves-side edge of the support strip 12, which becomes deeper from the side edge of the element in the direction of the water guide channel and has its lowest point in the transition area to the water guide channel 17.
  • a corresponding collecting channel 19 is provided on the eaves-side edge of the groove 20 which runs transversely to the plate in the lower third of the thermal insulation board 10 and likewise opens at its lowest point into the water guide channel 17.
  • This groove 20 is used to insert the tile lugs when laying the water-bearing roof panels.
  • the position of the collecting troughs 18 and 19 and the water guide channel 17 can also be seen in FIG. 5.
  • the collecting channels 18 and 19 run from their deepest point shown in the direction of the lateral edge of the thermal insulation boards, practically up to the level of the surface of the support strip 12 or the base surface of the groove 20.
  • This design of the collecting troughs 18, 19 and the water guide channel 17 ensures a safe water flow, so that the water flow path in the lateral fold does not immediately pass into another fold due to the inclined guidance of the lateral fold, but ends by the displacement in the area of a collecting trough which is safely drained from the water to the water channel.
  • thermal insulation boards according to the invention conventional thermal insulation boards with vertical lateral butt joints can also be laid together, which then results in the situation that the lateral butt joints are inevitably displaced when the next but one row of elements is laid with conventional elements.
  • the water is carried over the oblique side joint and in the other row of elements over the perpendicular side joint and in each case reaches the collecting channel 18 of the element on the eaves side.
  • Fig. 1 the crossing point of four elements is shown, in which the lateral water guide grooves 22 and 23 according to FIG. 4 from a plane on the ridge-side plate edge in a plane lying in or under the top of the support strip 12 obliquely upwards into a on the eaves-side edge lying level rises, which is higher than the underside of the cover strip 13. It can be seen from the illustration that with only a slight displacement of the lateral joint from one row of elements to another row of elements, the water masses flowing off through the lateral collecting channels 23 reach the transverse collecting channels 18 and be derived to the water channel.
  • Fig. 3 the side edge regions of two adjacent thermal insulation panels 10 are shown in an exploded view in a plan view to explain a further advantage of the invention, which additionally results from the inclined guide of the side fold.
  • the roof panels When laying the individual thermal insulation boards, they support each other. If the roof panels are laid after laying, the roof load results in a downward force component L1, which in the area of the side fold is broken down into a longitudinal component L2 and a horizontal component L3.
  • This horizontal component L3 has a favorable effect, namely because there is a shooting pressure in the rebate, which tries to reduce the gap between two adjacent elements due to the roof panel load if the usual displacements and adjustments result after the roof has been installed.
  • This horizontal component L3 and the resulting tendency to reduce the lateral joint spacing has the advantage that the joint can absorb only very little water and thus the risk that the collecting channel 23 overflows in the region of the side fold is further reduced.
  • the measures of the invention with the side fold running obliquely to the vertical ridge direction and in combination with the collecting troughs and the water guiding channels as well as the side folds running from the underside of the support strip to the top of the cover strip result in a safe water flow in all respects, by Element for element the water is always led to the surface and penetration of water even at the crossover point of elements is definitely excluded. This results in a very high level of security against ingress of water, even if an offset side rebate guide is not or cannot be carefully observed when laying the individual thermal insulation boards.
