Definitions

• Sheet material and method and device for securing the material.
• the present invention relates to a method for anchoring a foil material to an underlying base, as well as an arrange ⁇ ment for implementing the method.
• Norwegian Patent Application NO. 85.0209 discloses a roof Q covering material in the form of a foil consisting of a weldable, weather-proof plastics material reinforced by a reinforcing material such as a polyester web, fibre glass web or other suitable material, welded on to the foil material is a fastening flap extending across the longitudi- 5 nal direction of the foil material and where the flap welded on preferably shows greater mechanical strength than the foil material itself.
• Such a foil material may be anchored to a roof when through 0 the flap is passed a self-drilling, self-tapping screw which is further passed through the insulation, the vapour seal and down into an underlying steel profile.
• such a fastening method will entail 5 . -perforation of the vapour seal, thus causing its function to be reduced.
• a fastening arrangement is provided for such a roof foil, whereby a proofing of the 0 vapour seal is ensured, so that neither vapour nor water can be forced past it, and it can thus serve as a second sealing layer with its separate drainage system.
• a sealing foil is anchored 5 to a base, such as a roof, by the passing through the insulation of an elastic and ductile connector element which may take in the form of a chord, wire, strap or in the form of a metal structure fitted with a spiral spring, one end of the connector element beelng fitted with a disc with a piercing hole and a seal.
• the disc is fastened on top of the vapour seal by means of a screw or a nail, depending on the base, and the sealing material will provide a vapour tight seal where the nail/screw penetrates the vapour seal.
• the other end of the elastic element is attached to the flap and pulled tight if necessary.
• the flap may be fitted with piercing holes reinforced with eyelets or such like, or the flap may be shaped like a pocket through which a stave of some kind is passed and fastened via holes or slits in the pocket to the elastic element.
• FIG. 1 shows in outline the anchoring of a foil to a base
• figures 2 and 3 show various embodiments of the new ancho ⁇ ring arrangement
• figures 7a and 7b show a different enbodiment of the foil material to be anchored, in that the material, instead of a transverse separate fastening flap is fitted with a number of eyelets arranged along the longitudinal edge of the roll material
• fig. 8 shows a drawing in perspective where the roll material of figures 7a and 7b is laid out on an underlying base.
• a foil 1 with a flap 2 Shown in fig. 1 is a foil 1 with a flap 2.
• the foil 1 may be of a conventional type or of the kind described in Norwegian patent application No. 85.0209. Underneath the foil 1 is arranged an insulating layer which rests on a vapour seal 4 which again rests on a firm underlying base 5, indicated in the drawing as being a concrete base.
• the foil 1 is held in place via the flap 2 by means of a strap 6 which is fastened to the underlying base 5 by means of a screw or a nail or such like 7.
• the proofing of the vapour seal 4 is achieved by means of a combination of a stop ring of soft metal with an underlying rubber washer, indicated by 8, so thet when the screw/the nail is pulled down into the underlying base, the ring will form a close fit to the vapour seal and the underlying covering.
• the strap 6 is passed through the insulation 3 and fastened to the flap 2 which may have a pocket 15 provided in which a force distributing stave 10 has been inserted. Around this the strap 6 is passed and attached by means of a suitable arresting device 9.
• fig. 3 is shown in greater detail the point of fastening between the flap 2 and the strap 6 which has been passed round the stave 10 and fastened with a fastening clamp 9.
• the fastening clamp 9 may be replaced by a knot which is pulled by hand.
• the fastening clamp 9 may also be a snap-lock with an automatic locking device through which the strap 6 may be guided and pulled tight as desired by pulling at the loose end 11 of the strap 6.
• 12 indicates a clip or a hook which is hooked on to a stave, an eyelet or such like.
• fig. 5 is shown in outline a further embodiment where the elastic connection 6 has been replaced by a spiral spring 13 of a diameter to allow fitting tools and screws to be fitted through it, so that the screw may be passed through the fastening device 8.
• the fastening device may be fitted with clips 12 of the same type as shown in fig. 4.
• the clamp 9 shown in fig. 3 has been replaced by a welded Joint 14, which na ⁇ turally assumes that the strap 6 is of a weldable plastics material.
• the welded -joint may be implemented by any welding equipment suitable for a plastics material.
• the present invention is described in connection with anchoring of a foil material of the nature disclosed in Norwegian patent No. 85.0209, consisting of a web of a weldable material provided with a number of fastening flaps which extend across the longitudinal direction of the foil material.
• the present invention may, however, also conveniently be used on a new web material in the form of a foil consisting of a weldable, weather-proof plastics material which is reinforced with a reinforcing material such as a polyester web, fibre glass web or another suitable material, but, instead of being provided with fastening flaps, has arranged along one longitudinal edge, separate holes, for example in the form of piercing eyelets, preferably passed through a backing welded on of a weldable material which may be of the same material as the foil itself.
• the eyelet may be arranged in a position outside the edge of the web material by a number of rein ⁇ forcements having been welded on along it, in which the piercing eyelet has been arranged.
• fig. 7a is shown a foil to the web edge of which is welded on a reinforcement 17, through which has been passed an eyelet 16.
• the reinforcement 17 is shown as being welded on to the web material 1 in such a manner that the eyelet 16 is positioned outside the web edge of the foil 1.
• the desired length of the foil material is rolled out on the base, and the longitudinal row of eyelets are anchored to the base as described previously.
• the next length of foil material is then rolled out, so that one of its edges overlaps the reinforcements 17 and are welded on to the reinforcements 17 of the newly laid out foil in turn are fastened as described above.
• .in fig. 8 is shown laid out foils la, lb and lc laid out and anchored to an underlying base by the foil la being laid out first and the eyelets in the reinforcements 17a being anchored to the underlying base as described previously, and after that, the foil lb being welded on to the foil la, thus forming the welded Joint 18b. In the same manner the foil lc is welded on to the foil lb along the welded Joint 18b.
• one edge of foil with reinforcements 17 and eyelets 16 will form a "fastening flap" when the subsequent length of foil is welded in an overlapping manner to the preceding web material.
• the longitudinal spacing of the individual eyelets 16 may be varied, depending on the expected strain.
