Definitions

  • the invention relates to a windproof roof structure according to the preamble of claim 1, and an assembly method according to the preamble of claim 10, in particular for the renovation of old roofs.
  • a well-known windproof roof structure consists of rafters and battens as well as roof covering panels suspended from them with noses. Flat wind-blocking elements are attached under the roof covering panels.
  • a first, very complex renovation method is to clear away the old building roof including the roofing slabs and the roof battens except for the sections and to assemble the roof completely like a new building with a wind barrier, as shown above.
  • Such film trays have only a small width, are lined up side by side in a cassette shape and require complicated edge fold designs in the side area for water drainage and wind sealing.
  • the film trays only lie on top of one another in the overlapping areas and are not connected there.
  • With a square meter of covered area there are up to 10 running meters of partly wind-leaky covering joints. This means that the required windproofness, e.g. according to DIN, not possible.
  • Another well-known sub-roof for roofs covered with roofing panels (DE-AS 17 59 073) consists of a plastic film laid on the roof battens, which is held in place by the hanging tabs of the roofing panels.
  • the plastic film is covered with heat-insulating elements that fill up the spaces between the roof battens.
  • the plastic film extends from the ridge to the eaves and is intended to seal the roof. Laying a large-area plastic film from the ridge to the eaves, which is then only held by the roofing slabs, should be possible only with great difficulty, particularly in the case of wind movements, so that such a roof structure has not been used in practice.
  • the object of the invention is to use simple means to create a windproof roof structure with a gapless and largely adhesive-free structure To create a wind barrier and to propose a suitable, simple and inexpensive assembly process.
  • a roof foil is used as the wind blocking element, which is applied to the roof surface area-wide in overlapping foil webs that can be unwound from foil rolls, in such a way that the foil webs are laid one on top of the other from the foil rolls in stripes over the roof battens and with overlapping edges on the roof battens and are fixed with holding means.
  • the holding means are section-wise, cross-sectionally U-shaped clamping profiles that can be plugged onto the roof batten from above and are lined up on the roof batten. This results in a tight connection and fixing of the film webs as well as stable tread edges and film protection during assembly.
  • This provides a complete wind barrier especially for renovations of old roofs, whereby the roof structure is not increased overall.
  • the wind barrier can be attached easily and inexpensively, since the roof battens do not have to be removed and the roof covering plates only have to be covered.
  • the attachment and installation of the roof foil is easy thanks to the clamping profile, whereby the clamping profile connects overlapping foil sheets in a windproof manner and fixes them to the roof batten.
  • the clamping profiles also result in tread edges on the roof battens, so that the roof surface can be walked on without damaging the rolled-out film webs.
  • a complete wind blockage of a roof is possible, which can be produced on all roofs, but in particular with little effort in connection with a covering and renovation of an old building roof. Strong thermal insulation can, if necessary and the rafter spaces are accessible, preferably be installed from the inside of the roof.
  • the laying of the roofing film becomes particularly simple if the film rolls only have a width corresponding to only one roof distance plus an upper and a lower overlap edge.
  • a slat spacing z. B. from 36 cm from the top edge of the slat to the top edge of the slat results in a suitable film web width of approx. 50 cm taking into account the usual slat thicknesses and slat widths.
  • these foil webs lay around the roof battens without further tension, so that the clamping profiles hold well.
  • a running of the long foil webs to be unrolled is practically impossible due to their small width or can be easily compensated for due to the small width.
  • the rolled-up film webs are secured on the film rolls so that they can be rolled off at least at the edge by an adhesive.
  • an adhesive This allows the film rolls, which have already been partially unrolled stay on steep roofs without additional roll-off protection.
  • Such roll-off protection can be achieved by means of a narrow adhesive strip which is also rolled up when the film roll is rolled up.
  • Another simple measure is to place an edge of the rolled-up film about 2-3 cm in an adhesive such. B. to dip a wallpaper glue. Since the required roof foils are supplied on the foil rolls in the length of the previously measured roof width so that they do not have any first eaves overlaps, a narrow adhesive strip can, for example, be rolled up without any additional work after measuring and rewinding. As a result, the film rolls are easy to unroll and still do not slide off the roof.
  • a diffusion-open or diffusion-closed roof foil can be used. If an additional thermal insulation is used on the roof foil between two adjacent roof battens, a diffusion-open roof foil according to claim 4 is to be preferred, particularly in connection with an internal insulation, the roof foil lying between the thermal insulation elements. In previous cassette systems with load-bearing film trays, this is not possible, since films that are open to diffusion cannot generally be drawn into film trays.
  • the U-shape of the clamping profiles means that the roof membrane is held between the roof battens in one level below the top of the roof battens. This creates a continuous free space that according to claim 7 is well suited for inserting thermal insulation.
  • a compressible thermal insulation is preferably used, which according to claim 8 can consist in particular of mineral wool panels with a thickness corresponding to the height of the roof battens or the U-leg length. Due to the compressibility, the roof battens can be sealed tightly. In addition, the lugs of the roofing panels press into the thermal insulation without hindrance.
  • rigid insulation panels can also be used as thermal insulation, which may have a cutout in the area of the roof panel lugs.
  • its U-shape has a first, freely projecting longitudinal web as an extension of the U-base in the direction of the eaves, under which a ridge-side edge of thermal insulation can be inserted. This ensures that the inserted thermal insulation boards are held securely and easily during assembly and later.
  • thermal insulation panels made of rigid material are also suitable according to claim 10, the two parts of which are movable and prestressed against one another in the first eaves direction. When such thermal insulation panels are attached, their two parts are pushed together and the ridge-side edge is inserted under a longitudinal web of a clamping profile, if necessary.
  • a roof strip twice the width of a roof covering strip is made from the covered right roof side covered from the eaves to the ridge and the roofing slabs are removed from the roof and stored temporarily.
  • a roof covering strip can have a width of 2 or 3 roof covering plates, for example, when covering with roof tiles.
  • a film sheet from the right roof side, starting from the bottom, a film sheet the width of a roof covering strip is unrolled from a film roll over the roof battens, fixed on the right roof side and fastened windproof with the overlapping overlap edges on the assigned roof battens using a clamping profile.
  • the clamping profile has approximately the length corresponding to the width of a roof covering strip.
  • the individual film rolls remain on top of each other on the roof battens. In the case of not too steep roofs, these film rolls hold without further measures.
  • the roll-off protection according to claim 3 is advantageously used so that the film rolls do not slip even on the steepest roofs.
  • insulation boards are inserted between the roof battens in the width of a roof lath spacing and in a length approximately corresponding to the width of a roof covering strip in the area of the rolled-up film webs.
  • this roof covering strip prepared in this way is then covered again with roof covering plates which are taken from an adjacent roof area which has not yet been covered.
  • One roof covering strip is uncovered one after the other and covered again after the foil sheets and insulation panels have been attached. The last left roof covering strip is then covered with the roof covering plates which were initially removed from the roof.
  • This assembly process can be carried out quickly and easily, in particular even with strong wind movements, and excellent windproofness is achieved largely without adhesive.
  • Fig. 1 shows a plan view of a roof side 1 of an old building roof.
  • On the left side is the original, previously common roof construction, in which only rafters 3 are attached to rafters 2, which are covered directly with roofing panels 4.
  • Such a roof structure is to be improved with regard to windproofness, snow reliability and thermal insulation, as shown in the right part of FIG. 1.
  • the roof is covered in a right, relatively wide edge strip. These covered roofing sheets are removed from the roof and stored. In the case shown, the Row by roll of three film webs 5, 6, 7 from bottom to top and covering the corresponding rolls in the area of the uncovered strip and fixed with clamping profiles 8. Then mineral wool panels 9 are inserted as thermal insulation. This strip is then covered with the finished sub-roof with roofing slabs that are removed from the originally covered area. In strips, the entire roof is renovated from right to left.
  • Fig. 2 a cross section along the line A-A is shown enlarged. From this it can be seen that the film web 5 is guided over the roof batten 3 and is fixed to the roof batten 3 by the clamping profile 8.
  • the clamping profile 8 is U-shaped in cross section.
  • the U-base 10 merges at right angles into the ridge-side U-leg 11 without prestressing, so that there a 90 ° angle always lies exactly on the upper slat edge and forms an exact continuous hanging step for roof panel lugs 12 of a (only partially shown) roof covering panel 4 .
  • a freely projecting longitudinal web 13 is formed, under which a U-leg 14 on the eaves side runs backwards as a clamping leg with prestress, a wedge-shaped free space 15 possibly remaining depending on the slat dimensions and tolerance.
  • the free U-leg edges are bent up to bevels 16.
  • a ridge-side edge of a mineral wool panel 9 is held down by the longitudinal web 13, while an eave-side edge of a mineral wool panel 9 a is held by the roof panel nose 12.
  • the height of the U-legs corresponds approximately to the height of a 24-piece roof batten (shown in broken lines). This profile can also be used for a higher, 30 mm (or thicker) roof batten, as can be seen in FIG. 2.
  • FIG. 3 shows a roof structure which is similar in principle to that shown in FIG. 1, but the film webs 5, 6, 7 used are narrower and, in conjunction with overlapping edges, only extend over a slat distance in the first eaves direction.
  • roof battens 3, 3a are mounted on a rafter 2 in the transverse direction.
  • a lower film web 5, a middle film web 6 and an upper film web 7 then run over the rafters 2 and the roof battens 3, 3a.
  • the lower film web 5 extends over the crossbar 3 and is covered with a lower covering edge of the middle film web 6 and fixed there with a clamping profile 8.
  • the upper film web 7 overlaps the middle film web 6 in the area of the upper slat 3a, wherein there is also a fixation with a clamping profile 8a.
  • a roof covering plate 4 is suspended with a roof plate nose 12 on the ridge-side edge of the clamping profile 8.
  • thermal insulation panels 18 are inserted between adjacent roof battens 3 as thermal insulation, the thickness of which corresponds approximately to the roof battens height.
  • the thermal insulation panel 18 here consists of two parts 18a and 18b which are preloaded against one another in the first eaves direction by means of a spring arrangement 19.
  • a roof strip 20 has been covered approximately twice the width of a roof covering strip 21 from the eaves to the ridge, and the roof covering plates 4 have been removed from the roof and stored temporarily.
  • the roof covering strip 21 here has the width of approximately two roof covering plates 4.
  • film webs 5, 6, 7 of the width of the roof covering strip 21 are rolled off from the associated film roll.
  • the foil sheet must be fixed on the right side of the roof, for example by tacking; in the already advanced covering, as shown in FIG. 3, the right edge of the film web is already held by the clamping profiles 8 and the roof panels 4 placed on top.
  • the film webs 5, 6, 7 are fastened in a windproof manner by fitting the clamping profiles 8.
  • the clamping profiles 8 have approximately the length of a roof covering strip 21.
  • the film rolls assigned to the film webs 5, 6, 7, etc. remain one above the other on the left side of the roof covering strip being processed, as can be seen in FIG. 3.
  • insulation panels here mineral wool panels 9 are inserted in the width of the roof covering strip 21 between adjacent roof battens or clamping profiles 8 and then the roof covering strip 21 is again covered with roof covering panels 4 from below.
  • These roof covering plates 4 are brought over to the roof covering strip 21 from a left, adjacent, not yet covered roof area, similar to that shown in FIG. 1.
