Definitions

  • the invention relates to an element for sealing an outer corner of a component projecting over a roof surface, consisting of a flexible tab which has a substantially semicircular end section.
  • an outer corner is referred to as a corner from which an inner edge, an outer edge and an outer or an inner edge originate, in contrast to a case corner from which three outer edges originate or to an inner corner from which three inner edges originate.
  • Outside corners are formed in particular on a flat roof by accessories such as skylights or a raised parapet.
  • a sealing element In order to seal an outer corner, an element is required, hereinafter also referred to as a sealing element, which must cover an angular range of more than 360 ° overall.
  • a sealing element is known from German utility model G 79 20 530.
  • the known sealing element made of weather-resistant elastomers or thermoplastics consists of a sheet-like structure with an essentially circular outline and waves distributed over the entire circumference, the amplitudes of which increase linearly from the center of the structure to the edge, so that the structure has a full circular area around one additional circular sector area shows enlarged surface.
  • the central angle of the additional circular sector area depends on the dimension of the height angle of the outer corner to be sealed. For this reason, known sealing elements with different amplitudes of the shafts are produced, for example for the angular dimensions 90 °, 73 °, 60 ° and 45 °, the angular dimension corresponding to the height angle of the outer corner.
  • the invention has for its object to design a generic sealing element so that it can be used universally with a particularly simple manufacture.
  • the flap which has just been formed is provided in its end section with a sector-shaped recess arranged symmetrically to the protruding edge of the outer corner in the installed state, the central angle of which is 20 ° to 60 ° and the tip of which is rounded, and in addition to this Recess corners of the end section are rounded.
  • Such a sealing element can be punched out of sheet-like starting material such as a roofing sheet or a sealing sheet by means of a simple punching tool.
  • the sealing element can be installed in the area of the outer corner in such a way that the cutout runs in the direction of the edge of the outer corner protruding from the roof plane or in the opposite direction. If a first sealing element is applied in the area of the outer corner in the first-mentioned direction and a second sealing element in the opposite direction, the tips of the recesses being arranged at a distance from the corner, the sealing elements partially overlap and completely cover the outer corner. It is expedient to make the covering sealing element smaller than the sealing element below.
  • sealing element in a circular manner, the end section forming a semicircular shape which forms the rest of the tab Connects sealing section, the radius of which corresponds to that of the end section.
  • an elongated sealing element in which the end section adjoins a tongue-shaped sealing section forming the rest of the flap, the tip of which is rounded and the base width of which corresponds to twice the radius of the end section.
  • the radius of the end section should be at least 70 mm, preferably more than 100 mm.
  • a snug fit of the sealing element to the surfaces starting from the outer corner is particularly possible if the central angle of the recess is 30 ° to 50 °, preferably 40 °.
  • the tip radius of the rounding of the tip of the cutout and the corner radii of the rounding of the corners of the end section lying next to this cutout be at least 5 mm, preferably 15 mm training amount.
  • Polyisobutene, polyvinyl chloride or bitumen is recommended as a flexible material for the sealing element.
  • the assembly of the element is particularly easier if it is reinforced with plastically deformable material such as expanded metal.
  • An expanded metal mesh made of rustproof metal such as aluminum, embedded in the element, is recommended as a reinforcement element.
  • the expanded metal mesh advantageously has a thickness of 0.2 to 0.8 mm, a mesh length of 3 to 12 mm and a mesh size of 2 to 8 mm.
  • the sealing element according to the invention can in particular be applied to a bituminous roofing membrane in the welding process, to a highly polymeric roofing membrane also in the source welding process or in the hot gas process.
  • the application of the sealing element according to the invention is particularly facilitated if it is coated on one of its two sides with self-adhesive material.
  • FIG. 1 shows a sealing element according to the invention consisting of a circular tab 10 made of 4 mm thick polyisobutene flat material, which has a semicircular sealing section 12 and a substantially semicircular end section 14.
  • a sector-shaped recess 16 is arranged in the end section 14, the radially extending flanks 18, 20 of which enclose a central angle 22 of 40 °.
  • the tip 24 of the sector-shaped recess 16 is rounded off with a tip radius 26 of 15 mm.
  • the corners 28, 30 lying next to the sector-shaped recess 16 are each rounded off with a corner radius 32, 34 of 15 mm each.
  • the radius 36 of the end section 14 and of the sealing section 12 is 150 mm.
  • FIG. 2 shows a second sealing element consisting of a circular tab 40 made of 4 mm thick polyisobutene flat material, which likewise has a semicircular sealing section 42 and an essentially semicircular end section 44.
  • the End section 44 has a sector-shaped recess 46 whose radially extending flanks 48, 50 enclose a central angle 52 of 40 °.
  • the tip 54 is rounded off with a tip radius 56 of 15 mm.
  • the corners 58, 60 lying next to the sector-shaped recess 46 are each rounded off with corner radii 62, 64 of 15 mm each.
  • the radius 66 of the end section 44 and of the sealing section 42 is 115 mm.
  • the distance between the center points of tip radius 56 and radius 66 is 43 mm as in the sealing element according to FIG. 1.
  • FIG. 3 shows a further sealing element consisting of an elongated tab 70 made of 4 mm thick polyisobutene flat material, which has a tongue-shaped sealing section 72 and an essentially semicircular end section 74.
  • a sector-shaped recess 76 is arranged in the end section 74, the radially extending flanks 78, 80 of which enclose a central angle 82 of 40 °.
  • the tip 84 is rounded off with a tip radius 86 of 15 mm.
  • the corners 88, 90 lying next to the sector-shaped recess 76 are rounded off with corner radii 92, 94 each of 15 mm.
  • the radius 96 of the end section 74 is 115 mm.
  • the distance between the center points of tip radius 86 and radius 96 is 43 mm as in the sealing element according to FIG. 1.
  • the wider end 98 of the tongue-shaped sealing section 72 merges into the circular arc 100 of the end section 74.
  • the narrower end 102 of the tongue-shaped sealing section 72 is rounded in a circular arc.
  • FIG 4 the arrangement of a first tab 10 on an outer corner 104 at the foot of an orthogonal dome 106 is shown in perspective.
  • the sector-shaped recess 16 is arranged symmetrically to the vertically projecting edge 108 of the light dome 106.
  • FIG. 5 shows the complete sealing of the area of the outer corner 104 from FIG. 4, a second smaller tab 30 being applied above the first tab 10, the sector-shaped recess 46 of which is arranged in the opposite direction to the sector-shaped recess 16 of the first tab 10.
  • FIG. 6 similar to FIG. 5, the complete sealing of the area of an outer corner 110 of a light dome 112 with an obliquely protruding edge 114 is shown.
  • the sector-shaped recesses 16, 46 are not opened as far as is necessary in the case of an orthogonal dome light 106 according to FIGS. 4 and 5.
  • the flaps 10, 30 can therefore be used universally for outside corners with edges protruding at any height angle.
  • FIG. 7 similar to FIG. 5, the arrangement of a first tab 10 on an outer corner 104 at the foot of an orthogonal light dome 106 is shown in perspective.
  • two sealing sheets 116, 118 butt together.
  • the edge 108 is sealed by means of the tongue-shaped sealing section 72 of an elongated tab 70.
