EP0090245B1 - Roof closure - Google Patents

Description

The invention relates to a roof closure, consisting of an angled profile (9) arranged along the flat roof edge and filling material (22) receiving it, with a first leg (10) pointing upwards on the flat roof edge and an openwork element supported on the roof skin (8) Part.

An angled plate made of concrete is known, which is arranged along the edge of the roof on a roof skin, the inner, vertical leg fixing the adjoining insulating plate and limiting the gravel fill.

The disadvantage of this construction is that the concrete slab is very heavy and can cause damage to the roof covering, especially when laying. In addition, expensive fittings have to be specially made for all corners.

Also known is a metallic T-shaped roof closure (US-A-3 665 663), in which the longer vertical leg lies in front of the cladding and the shorter, opposite vertical leg points upwards. To drain water, openings are arranged on the inside of the shorter leg and on the underside of the leg resting on the roof, which lead to an inner channel system which has openings on the end face of the longer vertical leg.

With this roof closure, the water must drain through a narrow sewer system, which can easily become clogged with dirt or in winter with frost, which leads to unwanted overflow when there is a large amount of water.

The invention has for its object to find a roof termination that can be laid without great effort and can be easily adapted to the roof geometry and the static requirements as an edge boundary, which allows a clean connection of thermal insulation boards and / or gravel.

The object is achieved according to the invention in that a further leg (14) on the side opposite the first leg and adjoining the perforated part points upwards.

This edge formation can be used on flat roofs. Such a roof termination is particularly advantageous for a duo flat roof in which part of the thermal insulation lies above the roof skin. The profiles can be made of aluminum, zinc, copper, stainless steel or plastic. Since they are only installed from above on the edge of the roof, they are easy to handle and can be adjusted by simple cuts for corner designs. The perforation hardly impedes the water drainage. By filling with gravel, for example, uniform coverage is achieved over the entire roof area. Furthermore, the amount of filling material can be varied by the height of the legs, so that any required contact pressure can be set.

In a special embodiment, the legs provided with edge reinforcement are vertical, the outer leg being shorter than the other.

The upper edge of the leg can be stiffened by a grooved plastic strip or by an additional bevel, so that it does not bend under mechanical stress. Furthermore, the outside narrow leg is not or hardly visible to the viewer from the ground. So the often ugly high borders as a screen can be dispensed with.

In another embodiment, a vertical leg of a right angle is arranged next to the inner leg, the other leg of which rests on the roof skin.

By connecting the two legs, for example by means of an upper edge rebate, the roof edge is integrated deeper into the roof structure, which provides additional protection against storms.

Of course, it is also possible to use a continuously folded sheet instead of the two profiles.

In a further embodiment, an aperture is arranged in front of the outer leg.

The claimed construction allows the panel to be easily attached if this is desired for architectural reasons.

In one embodiment, self-adhesive tapes are fastened under the surfaces of the profile and angle lying on the roof skin.

By pulling off the protective strip from these tapes, the roof edge can simply be glued on, the weatherproof tapes should be attached as far as possible in the direction of the water drain.

An example of the invention is shown in the drawing and is described below.

On a wall 1 is a concrete ceiling 2 with cover 3 on the edge by a cement chipboard and an exterior plaster. The concrete ceiling 2 in turn carries a thermal insulation layer 5 with a wooden plank 6 on the edge for fastening the rain gutter 7. There is a waterproof roof skin 8. The roof end consists of a profile 9 with a shorter leg 10 including edge fold 11, middle part 12 with perforations 13 and longer Leg 14 with edge fold 15 and an angle 16 with a vertical leg 17 including overlapping edge fold 18 and horizontal leg 19 with perforations 20, the latter and the rest of the roof being provided with a thermal insulation layer 21. Profile 9 and insulation layer 21 are weighted with gravel as filler 22. The self-adhesive tapes 23 connect the profile 9 and the roof skin 8.

Claims (5)

1. Roof stop, consisting of an angled section (9) which holds filling material (22), is arranged along the edge of the flat roof and has a first side (10), pointing upwards, at the edge of the flat roof and a perforated part (12) resting on the roof skin (8), characterised in that another side (14) which is at the side opposite the first side (10) and adjoins the perforated part (12) points upwards.
