Definitions

  • This invention relates to a sealing layer which is adapted to be shaped with at least one upwardly curving edge portion and to be applied adjacent to an upwardly di ⁇ rected surface, with the upwardly curving edge portion lo- cated adjacent to said surface.
  • the sealing layer is de ⁇ signed for application to roofs as a covering layer thereon, is mouldable into shape permanence so as permanently to form the upwardly curving edge portion or edge portions prior to the mounting of the sealing layer and possesses such rigidity that its upwardly curving edge portion or edge portions retain or substantially retain their shape after the mounting of the sealing layer adjacent to the upwardly directed surface.
  • the roof surface and the wall surface have usually both been coated with cove ⁇ ring material without provision of any construction joint between the roof and the wall. If the roof and the wall move relative to one another the covering material will readily crack in the fold between the roof-covering part and the wall-covering part. Particularly, roofs construc ⁇ ted in the fifties and sixties show such damages.
  • a new layer of roof covering material can be laid onto the dama- ged material.
  • the new sealing layer is laid on the roof surface, folded upwards along the wall surface and heat sealed to another sealing layer placed on the roof at a distance from the wall.
  • heat sealing with an open flame must not be carried out close to the wall as this would imply a very great risk of fire. Therefore, the new sealing layers placed on the roof and folded upwards along the wall must be given sufficiently large dimensions to make the sealing thereof possible at a sufficiently large distance from the wall. If the wall has a covering metal sheet applied to it this sheet often has to be dismounted in order to make it possible to extend the sealing layer to a satisfactor ⁇ - height on the wall. Dismounting of the covering metal sheet often necessitates cutting it and mounting it in position again after the application of the sealing layer, which is a circumstantial and time-consuming procedure.
  • sealing layers of materials mouldable into greater shape permanence Today, however, there are also available sealing layers of materials mouldable into greater shape permanence.
  • One such embodiment is described in EP, Al, 0 123 141 which discloses a sealing material which is mouldable into shape permanence and which includes an insert in the form of a metal wire netting.
  • the insert is wholly embedded in the roof covering material which comprises two elastomer layers, preferably of rubber. When applied to roofs the material should, however, be coated with a further layer of bitumen or other sealing composition.
  • the sealing layer according to the present invention is characterised in that it comprises at least one upper layer of bituminous material, preferably asphalt material, and at least one subjacent metal layer with apertures therein, preferably a metal netting, and that bituminous material from the upper layer engages the apertures of the metal layer as a result of the material from the bituminous layer having been heated and thus caused to melt into the apertures of the metal layer.
  • the sealing layer according to the present invention thus is relatively inexpensive and material-saving since it may consist of only two layers, viz. an upper bituminous layer and a lower metal layer. As one of the layers is of the same material that sealing layers for roof covering purposes usually consist of, the sealing of another roof covering to the sealing layer according to the invention is facilitated.
  • the sealing layer according to the invention thus provides the effect aimed at, viz. an inexpensive and simple manufacture of the sealing layer, an inexpensive and simple formation thereof and an inexpensive and simple mounting of the same, while retaining the shape imparted to it and making it possible to seal the sealing layer to the existant roof covering and/or to apply a new roof covering on top of the same.
  • the novel sealing layer can furthermore be made sufficiently large so that heat sealing can be performed at an adequate distance from the wall, and in spite of its size the sealing layer is easy to handle when mounted in position at the wall.
  • the sealing layer accor ⁇ ding to the invention constitutes a movement-absorbing ele- ment as there is no connection between any vertical sur ⁇ face of the building structure and the sealing layer.
  • fig. 1 illustrates part of a sealing layer according to the invention in a perspective view, various layers comprised in the sealing layer having been cut at various "points fig. 2 illustrates a section of the sealing layer according to the invention on line II-II in fig. 1; fig. 3 illustrates the sealing layer according to the invention in a side view at the mounting of the layer on a roof; and fig. 4 illustrates the sealing layer shown in fig. 3 in position on the roof after the mounting of the layer.
  • the sealing layer 1 shown in the drawings is adapted for use as roof covering material.
  • the sealing layer 1 is also adapted to be formed with at least one upwardly cur ⁇ ving edge portion la and to be applied adjacent to an up ⁇ wardly directed surface 2, with the upwardly curving edge portion la located adjacent to said surface 2, preferably without being attached thereto.
  • the upwardly directed sur ⁇ face 2 may be one side of a wall 3 or another part of a building that projects above the roof surface 4.
  • the sealing layer 1 is mouldable into shape permanence so that the upwardly curving edge portion la or the up- wardly curving edge portions can be formed prior to the mounting of the sealing layer. Moreover, the sealing layer 1 has such a rigidity that its upwardly curving edge portion or edge portions la retain or substantially retain their shape after the mounting of the sealing layer adja- cent to the upwardly directed surface 2.
  • the sealing layer 1 is mouldable, pre ⁇ ferably by manual permanent conformation, into a planar or substantially planar part lb and is formed by manual bending with at least one edge portion la which extends at right angles or substantially right angles to the planar part lb.
  • the sealing layer 1 is brought into its final or approximately final shape by manual work input at the site itself after the height of the upwardly curving edge portion la and the widht of the other, planar part lb has been determined.
  • an existant sealing layer 5 may remain undisturbed and, if deemed necessary, the sealing layer may be sealed thereto.
  • the conformation of the sealing layer 1 is carried out by determining the width of the other, planar part lb of the sealing layer. Its width shall be. so large that the dis ⁇ tance from the upwardly curving edge portion la to the edge portion lc of the part lb that does not curve in an upward direction will be sufficient to eliminate any risk of fire at or inside the upwardly directed surface 2 when the edge portion lc of the part lb is heated and thus sealed to another sealing layer 6.
  • the sealing layer 1 can be fixed with the aid of fastening means 7. These can be mounted by raising parts of an upper layer 10 of bituminous mate ⁇ rial from a subjacent metal layer 9 and by passing the fastening means 7 through apertures in the metal layer 9, whereupon the fastening means are secured and the upper layer 10 is replaced. Then, the edge portion 6a of the other sealing layer 6 can be placed on top of the edge por ⁇ tion lc, whereupon sealing is carried out with the use of appropriate equipment.
  • the height of the upwardly curving edge portion la is determined in such a manner that, after mounting said edge portion will project some distance in upward direction beneath said cover metal sheet 8. It may be necessary temporarily to bend aside said cover metal sheet in order that the upwardly curving edge portion may be pushed beneath it. Should the angular position of the upwardly curving edge portion la be altered at said bending or at other mounting steps, the correct angle can be resto-
  • the sealing layer 1 illustrated further ⁇ more facilitates the mounting thereof considerably as com- pared to the state of the art technique, and after mounting the sealing layer can be satisfactorily sealed since also the upwardly curving edge portion la thereof retains its shape and its position.
  • the sealing layer 1 may vary within the scope of the appendant claims.
  • the sealing layer may comprise a number of layers other than two, the metal layer may consist of a squared netting or wire netting, the thickness of the various layers within the sealing layer may vary as required and, if necessary, more than one upwardly curving edge por ⁇ tion la may be provided.

Abstract

Couche d'étanchéité adaptée pour présenter au moins une partie de bordure de forme courbée vers le haut, et pour être appliquée sur une surface tournée vers le haut, la partie de bordure courbée vers le haut étant adjacente à ladite surface. Ladite couche d'étanchéité est conçue pour être appliquée sur des toits sous la forme d'une couche de couverture, on peut la mouler afin qu'elle forme de manière constante la ou les parties de bordures courbées vers le haut avant le montage de la couche d'étanchéité, et elle possède une rigidité telle que sa ou ses parties de bordures courbées vers le haut gardent leur forme après le montage de ladite couche sur la surface tournée vers le haut. Relativement bon marché et nécessitant peu de matière puisqu'elle ne comprend que deux couches, ce qui facilite son application sur une couverture de toiture existante, ladite couche d'étanchéité (1) est caractérisée par le fait qu'elle comprend au moins une couche supérieure (10) en matière bitumineuse, de préférence de l'asphalte, et au moins une couche métallique ajourée sous-jacente (9), de préférence un treillis métallique, et par le fait que la matière bitumineuse (10a) de la couche supérieure (10) vient au contact des ouvertures (9a) de la couche métallique du fait que la matière (10a) de la couche bitumineuse (10) a été chauffée et par conséquent a fondu dans les ouvertures (9a) de ladite couche métallique (9).
