Definitions

  • the invention relates to a sealing device for a roof terminal, such as a flue gas discharge pipe or a ventilation pipe, through a flat roof, according to the preamble of claim 5.
  • the invention further relates to an assembly of such a sealy device and a discharge structure accommodated in a flat roof, according to the preamble of claim 1.
  • warm air will be able to escape from the space below the roof along the pipe, through the (circumferential) slits or slots which are formed between the pipe and the passage opening in the roof. Said warm air may then end up in areas adjacent or above the heat insulation layer arranged on the roof, which are upwardly closed off by a roofing attachment plate for the roof cover layer placed on the insulation layer extending about the roof terminal, such as a bitumen layer.
  • the temperature can be considerably lower, so that condensation will take place against the bitumen layer, and/or against the lower side of the roofing attachment plate, after which condensate can fall back and end up on the surface of the insulation layer in the clear opening - and will initiate the formation of fungi -, and/or on (wooden) parts of the roof construction which are prone to the action of moisture.
  • the invention has the object to improve on this and to that end provides - from one aspect - a sealing device for a roof terminal, such as a flue gas discharge pipe or a ventilation pipe, comprising a disc-shaped placement member, provided with a passage opening for the roof terminal, and attached to the placement member at the location of the passage opening a sealing annulus or sealing ring extending in the passage opening, made from flexible material for sealingly abutting the roof terminal, as discribed in claim 5.
  • a sealing device for a roof terminal such as a flue gas discharge pipe or a ventilation pipe
  • the sealing device can furthermore be a continuation of a vapour proof layer, so that when applying a vapour proof layer in a roof construction this layer is also present at the location of the roof terminal due to the sealing device according to the invention.
  • the sleeve stands upright from the disc, and is in line with the passage opening.
  • Said sleeve promotes the aligning of the sealing device and also ensures a stiffening of the disc, so that -when necessary- it can fixed flat on a roof also without additional attachment means, such as nails, for instance by a layer of heat insulating material extending over the disc.
  • the sleeve moreover, screens off the clear in the hole of the insulation layer (additionally) against (warm) air coming from the inside.
  • the sleeve can further -when of sufficient length - be used as means for attaching the roof cover layer.
  • the annulus or ring is attached in a boundary edge of the passage opening.
  • the sleeve is designed such that it tapers a little in a direction away from the placement member.
  • the annulus is attached to the sleeve itself, preferably in its end.
  • the annulus can be bent to at least the side of the sealing device which faces away from the sleeve, so that the sleeve will not impede the wanted deformation of the annulus and the diameter of the sleeve can be kept limited.
  • the annulus is detachably connected to the placement member, so that the placement member can possibly be used in the usual manner as a roofing attachment plate.
  • the invention provides an assembly as described in claim 1.
  • the slit around the pipe is then closed off at the warm side of the insulation layer, whereas moreover the insulation layer can be used for holding the sealing device.
  • the sleeve extends through the insulation layer, preferably a length beyond it top surface.
  • the sealing device connects with the placement member to a vapour proof layer which is arranged between the insulation layer and the support and sealing layer.
  • a vapour proof layer which is arranged between the insulation layer and the support and sealing layer.
  • the sealing device 1 shown in figures 1-3 is substantially shaped like a hat, however without the upper wall.
  • the sealing device 1 - preferably made of plastic - comprises a flat annular disc 2 and an upright sleeve 3, which are formed as one unity.
  • the annular disc 2 and the sleeve 3 limit a passage 14 for a ventilation pipe or flue gas discharge pipe.
  • a ring 4 is attached - preferably in a detachable manner (such as by snapping) - which forms a flexible circumferential lip and to that end can be made from TPE.
  • the sealing device 1 of the figures 1 and 2 is situated at the location of a vertical hole 13 through a flat roof 5.
  • the flat roof construction is built up from a concrete plate 6, which upwardly screens off the space B below the roof.
  • a layer of insulation material 7 is arranged, and on it a layer of bitumen 8. This regards a so-called hot-roof construction.
  • the layer of bitumen 8 is sealingly attached with the edge to the upper surface of the ring 12 of the usual roofing attachment plate 10, which is further provided with an upright sleeve 11, which close-fittingly engages about ta pipe 9, which extends through the hole 13 and at its upper side is covered by a precipitation screening ring 15.
  • the diameter of the roof terminal 9 is smaller than the one of the hole 13.
  • the warm inside air may end up within the roof construction by means of rising in direction A. Because the temperature of the outside air C is lower than the one of the inside air condensation may occur against the inner surface of the sleeve portion 11 of the roofing attachment plate 10 and against the layer of insulation material 7, at least when a sealing device 1 would not have been placed.
  • the sealing device 1 Because of the sealing device 1 with the flexible ring 4 a chimney effect is prevented so that an air flow A will no longer occur, at least cannot reach relatively cold construction parts. Pressure levelling via the hole 13, along the outer side of pipe 9 can no longer occur.
  • the flexible circumferential lip 4 sealingly abuts the outer surface of the pipe 9.
  • the sleeve 3 of the sealing device 1 screens off the clear of the hole in the layer of insulation material 7. It is advantageous here when the sleeve 3 extends until at the top of the layer of insulation material 7 and almost connects to the roofing attachment plate 10. It is also possible that the sleeve 3 further extends upwards until the ring 15, so that possibly the layer of bitumen 8 can be attached to it and a separate roofing attachment plate can be left out.
  • sealing device - after removal of the ring 4 - can be used as roofing attachment plate, for instance like the roofing attachment plate 10 in this example.
  • the sealing device 1 is placed flat on the top surface of the concrete plate 6 without attachment means such as nails.
  • the thickness of the annular disc 2 is kept as small as possible here, for instance 1 to 2 mm, in order that the layer of insulation material remains lying practically flat at the location of the sealing device 1.
  • the flatness of the annular disc 2 is guaranteed here by the stiffening influence of the sleeve 3.
  • figure 4 a cross-section through a flat roof 105 is shown, which just like the flat roof construction of figure 3 is a "hot-roof construction". Corresponding parts have similar reference numbers, increased by one hundred.
  • the flat roof construction 105 is built up from a concrete construction layer 6, a vapour inhibiting or vapour proof layer 116 arranged thereon, an insulation layer 107 arranged thereon and a bitumen layer arranged thereon.
  • a passage 114 is made, in which a roof terminal 109 can be included.
  • the sealing device 101 according to the invention is included in the roof construction 105, in a shape substantially corresponding to the one of the sealing device 1 of the figures 1-3 .
  • the disc 102 is placed contiguously to the vapour inhibiting layer 116, and as shown in figure 4A , the sleeve portion 103 tapers upwards.
  • sealing, flexible sealing annulus or sealing lip 104 is now attached to the end of upright sleeve 103, to which end the upper edge of the sleeve 103 is provided with a double circumferential ring 117, which rings define an upwardly opening receiving space 118 for attachment portion 119 of the annulus or lip 104 provided with integrally formed barb lips.
  • the lip or annulus 104 is furthermore provided with a sealing lip 120 extending to the inside and downwards over the inner ring 117, which sealing lip 120 sealingly abuts the surface of the pipe 109.
  • the wall of the sleeve 103 and the annulus or lip 104 thus forms a continuation of the vapour inhibiting layer until against the outer surface of the pipe 109.
