Description

Description Technical Field The present invention relates to a pipe penetration for a roof, in particular an exhaust pipe or ventilation connection for a flat roof.

PRIOR ART Before installing the flat roof, all pipes penetrating the roof must be sealed off in accordance with the SIA regulations. For this purpose, a vapor barrier is applied to the roof surface surrounding the tube, the vapor barrier being partially pulled up along the tube. The pipe is then surrounded with thermal insulation. Then a pipe border is attached to the thermal insulation. The pipe surround, the thermal insulation surrounding the pipe and the vapor barrier are then sealed together with a sealing layer.

This method is time-consuming and requires different people, since, for example, the pipe surround is installed by a plumber. This means an additional coordination effort of the individual people.

Description of the invention It is an object of the present invention to provide a pipe penetration for a roof in which the above-mentioned disadvantages are avoided.

This object is achieved by a pipe penetration with the features of claim 1. Further embodiments of the pipe penetration and a method for producing a pipe penetration according to the invention are defined by the features of further claims.

A pipe penetration according to the invention comprises a pipe enclosure with at least one through opening, a cuboid thermal insulation with at least one through opening which extends from an upper surface of the thermal insulation to a lower surface of the thermal insulation and a sealing layer. The pipe surround is arranged on the side of the upper surface of the thermal insulation and the through openings are aligned with one another. The gasket layer is connected to the pipe surround and the thermal insulation. The sealing layer completely covers all side surfaces of the thermal insulation. The pipe penetration further comprises a sealing plate with at least one further through opening, the sealing plate being arranged on the side of the lower surface of the thermal insulation and with the through openings and the further through opening being aligned with one another. The sealing plate projects beyond the side surfaces of the thermal insulation in the radial direction and the sealing layer is connected to the sealing plate.

Such a prefabricated pipe penetration has the advantage that it can be arranged on site in a very short time and with very little installation effort around a pipe which projects, for example, upwards through a flat roof made of reinforced concrete. For this purpose, the pipe penetration only has to be arranged around the pipe penetrating the roof and then the sealing plate must be tightly connected to the roof by heating or with an adhesive. The pipe penetration according to the invention can be used as a temporary construction time pipe penetration or as a final pipe penetration. In the case of a construction period solution, the tight connection to the roof is not mandatory, for example if no precipitation or other water entry on the roof is to be expected. Of course, the construction time pipe penetration can also be carried out with tight connections.

For example, the pipe surround is a plate made of sheet metal, for example made of stainless steel, copper or zinc with a sheet thickness of 1 to 2 mm. Alternatively, the pipe surround can also be made of plastic, for example of PVC with a wall thickness of 1 to 3 mm. The thermal insulation is, for example, made of plastic, for example expanded rigid foam made of polystyrene or polyurethane. Alternatively, the thermal insulation can also be made of stone or glass wool. Unlike hard foams, however, these are not accessible. The lateral dimensions of the thermal insulation can be 10 to 100 cm and the thickness can be 1 to 50 cm. The lateral dimensions of the panel can be essentially the same size as those of the thermal insulation or they can be smaller. For example, the plate can be made 10 cm less wide and 10 cm less deep, so that a strip of 10 cm in width of the thermal insulation projects laterally beyond the plate of the pipe surround. In such an embodiment, the sealing layer is connected to this strip of thermal insulation and to the sheet metal of the pipe surround. For example, the sealing layer and the sealing plate comprise bitumen sealing sheets with a thickness of 2 to 5 mm, also called roofing felt, for example with elastomer bitumen or rapid welding bitumen.

In one embodiment, the tube surround comprises a plate and at least one tube, the tube being connected at one end to an upper side of the plate. The plate and the tube can be welded, soldered or glued together. The through opening extends through the plate and the tube. As an alternative to the tube, a hollow profile with any cross-section can be used. The diameter of the tube can be between 5 and 40 cm.

CH 714 636 B1 If the pipe penetration is to be used, for example, for an exhaust pipe or ventilation connection, the pipe surround can be arranged on the thermal insulation in such a way that the pipe extends upward away from the thermal insulation. If the pipe penetration is to be used, for example, for a roof water inlet, the pipe of the pipe surround can extend downward from the side of the upper surface of the thermal insulation to the side of the lower surface of the thermal insulation. The pipe can extend through the thermal insulation and beyond its lower surface.

In one embodiment, the gasket layer comprises first tabs which are connected to the pipe surround and second tabs which are connected to the sealing plate. The first tabs are used for fastening to the pipe surround and extend over the entire length of the upper edges of the thermal insulation or the plate of the pipe surround. The second tabs are used for fastening to the sealing plate and extend over the entire length of the lower edges of the thermal insulation. The overlap with the pipe surround or with the sealing plate can be between 8 and 15 cm. The overlap with the plate of the pipe surround can be 10 cm. It is important that the distance between the brackets and the pipe of the pipe surround is at least 8 cm, i.e. that the plate is freely accessible up to a width of at least 8 cm. A further sealing layer according to the SIA standard can be connected to the exposed area of the plate at a later time. In order to connect and seal the sealing layer on the circumference of the thermal insulation with itself, a further tab is provided, which extends at least over the entire height of the thermal insulation and that of the plate of the pipe surround. The overlap can also be 8 to 15 cm for the other flap.

In one embodiment, the first tabs overlap, especially in the corner areas of the connection, with the plate of the pipe surround. Alternatively, the tabs can abut each other. For this purpose, the corner areas of the first tabs can be bevelled, for example at an angle of 45 degrees. The further tab for connecting the sealing layer to itself can also include beveled corner areas, for example at an angle of 10 to 45 degrees.

In one embodiment, the pipe penetration comprises a vapor barrier with at least one through opening, the vapor barrier being arranged between the thermal insulation and the sealing plate. The vapor barrier can comprise a carrier insert made of glass fleece or aluminum foil and a covering material made of elastomer bitumen. The side dimensions can be 10 to 100 cm and the thickness can be 1 to 5 mm. The contours of the vapor barrier can be identical to the contours of the lower surface of the thermal insulation. Alternatively, the passage opening in the vapor barrier can be smaller than that in the thermal insulation. The vapor barrier can be glued to the thermal insulation, for example with a mounting adhesive based on MS polymer. The vapor barrier can be glued to the sealing plate, for example with a one- or two-component adhesive based on bitumen. Alternatively, the sealing plate can be heated, which softens the surface and makes it sticky. The vapor barrier can then be glued directly to the sealing plate.

In one embodiment, the vapor barrier comprises a plate and at least one tube, the tube being arranged with an end face on an upper side of the plate.

The tube can be glued to the plate or it can rest directly on the plate. The through opening extends through the plate and the tube. The pipe is arranged in the through opening of the thermal insulation. The pipe of the vapor barrier can also be glued to the thermal insulation with a polymer adhesive.

In one embodiment, the pipe penetration comprises reinforcements which are connected to the sealing layer in the corner regions of the thermal insulation. The reinforcements include corner reinforcements for inside and outside corners. For example, the reinforcements comprise a jute fabric with an elastomer bitumen covering and a flame foil on one of the surfaces. The flame foil can be made adhesive by heating the reinforcement.

In one embodiment, the pipe surround, the thermal insulation and the sealing plate comprise two or more through openings, some or all of the through openings having the same diameter or some or all of the through openings having a different diameter.

[0018] In one embodiment, the pipe surround and the thermal insulation are screwed together. In this case, insulation dowels can be arranged in areas of the thermal insulation close to the edge and corresponding screw receptacles, for example in the form of through holes such as countersunk holes, can be provided in the pipe surround. The screw connection takes place before the sealing layer is connected to the pipe surround. After the sealing layer has been connected to the pipe surround, the screws, for example countersunk screws, are completely covered by the sealing layer. Alternatively, the pipe surround and the thermal insulation can be glued together. The thermal insulation and the sealing plate can also be glued together. For example, these elements can be glued together with an MS assembly adhesive such as Polyflex 444.

For all connections within each component of the pipe penetration and between two components of the pipe penetration, care must be taken that the connection points are tight.

The mentioned embodiments of the pipe penetration can be used in any combination, provided that they do not contradict each other.
