Definitions

  • the object of the invention is a covering in the form of a flexible webformed sheet which is especially suitable for roofs.
  • the invention is characterized in that on that side of the covering which faces the surface to be covered there are provided continuous ribs or flaps which are throughout connected with the inner surface of the covering.
  • the fundamental body of the covering is formed to be uneven and the flaps are provided transversely to the uneven portions.
  • the flaps or ribs conform substantially to the uneven portions of the fundamental body.
  • the uneven portions are provided advantageously in the form of corrugations or depressions and/ or elevations. Those portions can also be built by bucklings.
  • FIG. 1 shows a roof construction in which a covering in the form of a flexible sheet with ribs overlies a plurality of roof rafters.
  • FIGS. 2 and 3 show a covering according to the invention with elevations and corrugations, respectively.
  • the flexible sheet is shown with bucklings.
  • ribs are shown with various profiles.
  • FIG. 1 of the drawing shows a covering 1 in the form of a flexible sheet. On that side of the covering which faces the surface to be covered continuous ribs 2 are provided. The ribs 2 are throughout connected with the inner surface of the covering 1.
  • a covering of such kind can be manufactured of any flexible material, for instance of a synthetic or plastic.
  • the covering is shown substantially in that form in which it is discharged by the machine and will be seen to overlie a plurality of roof rafters RR on which it is supported in such a manner that the flaps or ribs 2 extend alongside the roof rafters and are secured thereto by such fastening means as nails or screws FM.
  • the fundamental body of the covering is even.
  • the fundamental body is provided with uneven portions.
  • These uneven portions can be corrugations, elevations and bucklings.
  • these portions are of an elongated form, the longitudinal axis of said uneven portions extending in the direction of the width of the sheet.
  • the ribs are arranged transverse to the longitudinal axis of the uneven portions, thus said ribs preferably extend in the longitudinal direction of the sheet.
  • FIGS. 2 and 3 of the drawing show coverings whereon the uneven portions are provided in the form of elevations 4, and in the form of corrugations 3, respectively.
  • 5 and 6 coverings are shown whereon the uneven portions are for-med by bucklings 5. Due to these bucklings the fundamental body of the covering for instance according to FIG. 4 is formed to have a cross sec tion which is in the form of bonded triangles 6.
  • FIG. 5 a covering is to be seen wherein due to the bucklings the fundamental body is given the form of bonded rectangles '7.
  • FIG. 6 shows a fundamental body the cross section of which is in the form of bonded trapezes.
  • the ribs substantially conform to the uneven portions of the fundamental body. Thereby it is guaranteed especially that the covering may be fastened at any required place. Besides, this kind of forming the covering adds to increase its stability.
  • the ribs 2 are provided with clearances or cutaway portions 9. Said clearances 9 in the ribs make it possible, too, to provide the covering with uneven portions 3, 4, 6, 7, 8, the ribs always conforming to the inner surface of the covering and being secured thereto.
  • the ribs are formed in one piece with the covering.
  • the uneven portions of the covering are provided by elevations, depressions or bucklings.
  • the clearances 9 are provided at those places where the tension or compressive strain is most intense, that is especially at the places of bucklings 5.
  • the ribs also can be provided with profiles as shown in FIGS. 7-9. Said profiles serve to provide a self-acting connection by means of the border ribs of two adjacent coverings.
  • the rib 2b is arranged within the scope of the one edge 15 of a covering 1 has projections it); those projections 10 engage corrugations or excavations 13 of the rib 2a within the scope of the other edge 14 of an adjacent covering 1 if the covering is in its Working position.
  • the profiles also can be formed in such a manner that only on the rib 2a or additionally there are provided projections 12 which in turn engage corrugations or excavations 11 on the rib 212.
  • the covering for instance is used as a roof sheathing and the one covering 1 is fixed by nailing the rib 2a to a rafter, the adjacent covering 1 need only to be pushed with its edge 15 over the preceding covering 1 and thus is fixed already along this edge by the engagement of the rib profiles.
  • the ribs 2 are arranged in such a manner that their distance one from the other cor responds to the usual distance of rafters or to a multiple thereof.
  • the ribs on the one edge 14 of the covering are arranged substantially directly at this edge 14 while the ribs within the scope of the other edge 15 of the covering are provided in some distance from this edge 15.
  • the depressions 3 and the elevations 4 may be provided also as continuous such portions.
  • the uneven portions may be arranged also in the longitudinal direction of the covering, while in this case the ribs will be arranged transversely thereto that is to say in the direction of the breadth of the covering.
  • the uneven portions can have any suitable form.
  • the ribs can also be arranged parallel to the uneven portions.
  • a covering for roofs and the like comprising, in combination, an elongated sheet of flexible plastic material having a first edge and an opposite second edge, said sheet being formed with elongated depressions on one and corresponding projections on the other side thereof respectively arranged in rows extending in one direction of said sheet; and a plurality of elongated, longitudinally subdivided parallel fiaps of sheet material extending spaced from and substantially parallel to each other and transverse to said rows and each being connected along one edge thereof to said sheet projecting from one surface of the same, said plurality of flaps including a first flap extending along said first edge of said sheet and at least one further flap arranged spaced from both said first and said opposite second edge of said sheet, with the spaces between the flaps themselves, and the space between said further flap and said opposite second edge of said sheet being free and unobstructed, so that the sheet portion between said further flap and said opposite second edge may overlie another covering along an edge thereof which corresponds to said first edge, while roof rafters may be received in said spaces and said covering
