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, especially for the renovation of old roofs.
- a well-known windproof roof structure consists of rafters and Roof battens and roof covering panels attached to them with noses. Flat wind-blocking elements are attached under the roof covering panels.
- a first, very complex renovation method is the old building roof including the roofing slabs and the battens except for clear the rafters and the roof as with a new building to build a wind barrier as shown above.
- Such film trays have only a small width and become cassette-shaped on the side strung together and require in the side area for water drainage and wind sealing complicated edge fold designs.
- the foil trays are located in the overlapping areas of cassette systems only on each other and are not connected there. At a Square meters of covered area result in up to 10 running meters partly windproof covering joints. This is with such systems the required windproofness, e.g. according to DIN, not possible.
- the object of the invention is a simple means windproof roof structure with a gapless and largely tack-free To create a wind barrier and a suitable, simple and inexpensive Propose assembly procedures.
- a roof foil is used as the wind blocking element in overlapping film webs that can be unwound from film rolls is applied to the roof surface such that the film webs from verge to verge from the film rolls in strips over the Roof battens and with overlapping edges on the roof battens one above the other are laid and fixed with holding devices.
- the holding means are in sections trending, U-shaped in cross section on the roof batten of clip-on clip-on profiles that are lined up on the roof battens are. This creates a tight connection and fixing the film webs as well as sturdy tread edges and film protection during assembly reached.
- the attachment and installation of the roof foil is easy thanks to the clamping profile possible, with the clamping profile overlapping foil webs windproof connects and fixes each on the roof batten.
- the clamping profiles result also on the roof battens, so that the roof surface without Injury to the rolled-out film is accessible. It is also through the clamping profile one step as a hanging and support surface for the noses the roofing slabs created on the roof battens, so that the film sheets also against an injury from the lugs of the roofing slabs are protected.
- Laying the roof foil becomes particularly easy when the foil rolls only a width corresponding to only one roof distance plus an upper one and have a lower overlap edge according to claim 2.
- a slat distance e.g. of 36 cm from the top edge of the staff to the top edge of the staff results from taking the usual slat thicknesses and Slat widths a suitable film web width of approx. 50 cm.
- These foil webs lay down with their overlapping edges without further tension around the roof battens so that the clamping profiles hold well.
- a runaway The long film web to be unrolled is because of its narrow width practically not possible or can be easily compensated due to the small width become.
- the rolled-up film webs are on the film rolls at least at the edge with an adhesive secured rollable.
- This allows the film rolls, which have already been partially unrolled lie on steep roofs without additional roll-off protection stay.
- Such roll-off protection can be achieved with a narrow adhesive strip can be achieved, which is rolled up when the film roll is rolled up becomes.
- Another simple measure is to roll up an edge of the Foil approx. 2-3 cm in an adhesive e.g. B. to dip a wallpaper glue. Because the required roofing films on the film rolls in length of the previously measured roof width, in order to avoid any first eaves overlaps to have, for example, after measuring and rewinding a narrow adhesive strip with no additional Operation with be rolled up. This makes the film rolls easy to unroll and still don't slide off the roof.
- a diffusion open or diffusion closed one Roof film can be used.
- a diffusion open Preferred roof film according to claim 4. With previous cassette systems this is not possible with load-bearing film trays, as they are open to diffusion Foils generally cannot be pulled into foil trays.
- the U-shape of the clamping profiles means that the roof membrane between the Roof battens are held in a 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. Is preferred uses a compressible thermal insulation according to claim 8 in particular from mineral wool panels with a thickness corresponding to the Roof slat height or the U-leg length can exist. Because of the compressibility there can be a tight fit on the roof battens. In addition the noses of the roofing sheets press in without hindrance thermal insulation.
- rigid insulation boards can also be used as thermal insulation be a cutout in the area of the roof panel lugs exhibit.
- its U-shape has a first, freely projecting longitudinal web as an extension the U-base towards the eaves, among which a ridge-sided Edge of thermal insulation can be inserted. So that during the Installation and later a secure and easy hold of the inserted thermal insulation panels reached.
- Claim 10 also two-part thermal insulation panels made of rigid material, the two parts of which are movable and preloaded against each other in the first eaves direction are. When installing such thermal insulation boards whose two parts are pushed together and the ridge-side edge, if necessary, under inserted a longitudinal web of a clamping profile.
- the roof is covered by the roof on the right a roof strip twice the width of a roof covering strip covered from the eaves to the ridge and the roofing tiles are removed from the roof and stored temporarily.
- a roof covering strip can be used for roofing, for example have a width of 2 or 3 roofing sheets.
- the process starts from the right roof side from below a film sheet the width of a roof covering strip unrolled from a film roll over the roof battens, fixed on the right side of the roof and with the overlapping overlapping edges on the assigned roof batten using a clamping profile attached windproof.
- the clamping profile has about each Length corresponding to the width of a roof covering strip.
- the single ones Foil rolls remain on top of each other on the roof battens. At These film rolls hold not too steep roofs 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.
- the width of the insulation boards may be increased a roof batten distance and in a length approximately according to the width a roof covering strip in each case in the area of the rolled-up film webs inserted between the roof battens.
- One roof covering strip is uncovered one after the other and covered again after attaching the membrane and insulation panels. The last left roof covering strip will then start with the roof covering panels removed from the roof covered.
- Fig. 1 shows a plan view of a roof side 1 of an old building roof.
- the original roof structure which was common in the past, in which only rafters 3 are attached to rafters 2 are directly covered with roofing tiles 4.
- Such a roof structure is said to be windproof, snowproof and Thermal insulation can be improved, as shown in the right part of FIG. 1 is shown.
- Fig. 2 a cross section along the line A-A is shown enlarged. From this it can be seen that the film web 5 over the roof batten 3 out and fixed by the clamping profile 8 on the roof batten 3.
- the clamping profile 8 is U-shaped in cross section.
- the U base 10 goes into the ridge-side U-leg 11 at right angles without pretension over, so that there is always a 90 ° angle exactly on the top edge of the slat is present and an exact, continuous mounting step for roof panel lugs 12 of a (only partially shown) roofing sheet 4 forms.
- U base 10 As an extension of the U base 10 towards the eaves, there is a freely projecting one Longitudinal web 13 integrally formed, under which a U-leg on the eaves side is set back 14 runs downward as a clamping leg with pretension, depending on the slat size and tolerance, it may be a wedge-shaped one Free space 15 remains.
- the free U-leg edges are to beveled 16 bent up.
- the height of the U-legs corresponds approximately to the height of a 24-piece roof batten (shown in dashed lines). This profile is also for a higher, 30's (or stronger) roof batten can be used, as shown in Fig. 2.
- Fig. 3 is a roof structure similar in principle as shown in Fig. 1, wherein however, the film webs 5, 6, 7 used are narrower and in Connection with overlapping edges in the first eaves direction only via extend a slat distance.
- FIG. 4 of a part 3 are on a rafters 2 in the transverse direction running roof battens 3, 3a attached. Over the rafters 2 and the roof battens 3, 3a then run a lower film web 5, one middle film web 6 and an upper film web 7.
- the lower film web 5 extends over the crossbar 3 and is with a lower overlap edge covers the middle film web 6 and there with a Clamp profile 8 fixed. Accordingly, the upper film web 7 overlaps Area of the top lath 3a, the middle film web 6, where also there fixing with a clamping profile 8a.
- a roofing slab 4 is with a roof panel nose 12 on the ridge-side edge of the Clamping profile 8 hung.
- thermal insulation compressible mineral wool panels 9, 9a Between adjacent roof battens 3 are as thermal insulation compressible mineral wool panels 9, 9a or two-part thermal insulation panels 18 inserted, which correspond approximately in their thickness to the height of the roof battens.
- the Thermal insulation panel 18 here consists of two parts 18a and 18b, which are against each other Movable in the first eaves direction via a spring arrangement 19 are biased.
- roof strip 20 From the originally roofed right roof side is a roof strip 20 about twice the width of a roof covering strip 21 from the Eaves have been covered up to the ridge and the roofing panels 4 were removed from the roof and stored temporarily.
- the roof covering strip 21 here has the width of approximately two roofing panels 4.
- foil sheets 5, 6, 7 covering the width of the roof covering strip 21 from the assigned film roll unrolled.
- the film must be on the right side of the roof fixed by tacking; in the already advanced coverage, as shown in Fig. 3, the right edge of the film is through the clamping profiles 8 and the roof panels 4 already held.
- the clamping profiles 8 have approximately the length of a roof covering strip 21.
- the film rolls 5, 6, 7, etc. assigned to the film rolls remain one above the other on the left side of the processed roof covering strip after unrolling, as shown in Fig. 3.
- roofing panels 4 are shown similar to that in FIG a left, adjacent, not yet covered roof area on the Roof covering strips 21 brought over.
