Coating and method for rehabilitating a rainwater gutter at the eaves of a water roof. - Ytbelåggning och forfarande for renovering av vid vattentakfot belågen regnvattenrånna.

The invention relates to a coating according to claim 1 and a method according to the preamble of claim 5 for rehabilitating a rainwater gutter at the eaves of a roof.

Replacing the entire gutter with a new one is often the cheapest way to repair a worn and leaking gutter. However, especially in apartment buildings, rainwater gutters are often used, the replacement of which is a very large-scale and potassium operation. In view of the latter cases, it is an object of the invention to provide a coating as well as a method for rehabilitating a rainwater gutter so that it does not have to be removed.

DE-A-3 640 634 discloses a gutter renovation element formed of a strip-like cladding profile adapted to the gutter to be renovated, with fastening profiles arranged on both longitudinal sides thereof for fastening the cladding profile to be renovated. The problem with this known solution is that it forms. there are several joints (between the cladding profile and the fastening profiles and between the cladding profile and the end pieces) which in practice it is impossible to make completely watertight or at least to remain watertight for long periods of time.

In order to eliminate the drawbacks associated with this known solution, the coating according to the invention is arranged and is characterized in that the top layer is bent into a single basin formed in one piece so that the top layer is bent and further formed 92512 between the upper gutter structure, that the top layer is attached to the edge wall of the inner wall of the rain gutter on the side of the building by means of mechanical fasteners, preferably by means of or around the drip tray therein.

In a preferred embodiment of the invention, the leveling layer is formed of a natural fiber mat and the cover layer is made of a thin copper plate, the thickness of which is preferably 0.3 mm or even less.

The method according to the invention is characterized in that the top layer is bent into a single basin consisting of one piece in such a way that the top layer is bent to form in addition to the gutter part side gutter sisåseinåmån bar top section mechanical kiinnikkeillå, preferably stainless teråksestå prepared using self-tapping screws and the Thereafter the pressure and bending of simple, preferably wooden or plastic painintyokaluja kåyttåen against the leveling layer be renovated gutter shape in accordance with, and and working påållikerros Additionally the kiinnitetåån building seinåstå etååmpånå the gutter edge bending påållikerros said edge or around the drip tray therein.

Advantageous developments of the invention will become apparent from the subclaims and from the accompanying description, in which the invention will be described in more detail with reference to the accompanying drawing, which shows a cross-section of a rehabilitated rainwater gutter.

92512 3

In the accompanying drawing, the rainwater gutter to be refurbished is generally indicated by reference numeral 2. In a typical case, where the coating according to the invention is preferred, the gutter 2 is formed of a body formed of thick flat irons 6 and exterior of a steel plate 7 as well as the actual gutter part formed of the steel plate 8.

The coating according to the invention comprises a leveling layer 3 made of a flexible material applied to the surface 8 of the rainwater gutter 2 to be renovated in a uniform layer. in which only an opening (not shown) is formed at the discharge pipe for the drainage of water.

The leveling layer 3 may be a sprayed or brushed layer, but in a preferred embodiment of the invention it is formed of a natural fiber mat. In a preferred embodiment of the invention, the top layer 4 is formed of a thin copper plate, the thickness of which is preferably 0.3 mm, but an even thinner material is also possible.

The leveling layer 3 is arranged to extend over the entire surface to be coated with the top layer 4. In this case, the leveling layer 3 enables the relative movement of the top layer 4, e.g. due to thermal expansion, between the rain gutter 2 and the top layer 4. In addition, the leveling layer evens out any irregularities on the surface 8 of the gutter 2 which could damage the top layer 4. Another part of the leveling layer 3 is to insulate the top layer 4 electronically from the water gutter 2 in order to prevent galvanic corrosion. In order to ensure that the possibility of galvanic corrosion is prevented, the surface against the leveling layer 3 of the copper plate forming the layer 92512 4 is preferably coated with plastic or a corresponding insulating layer.

The top layer 4 is preferably fastened from the upper part of the inner wall of the rainwater gutter 2 on the wall side of the building by mechanical fasteners 5. The fasteners 5 are preferably self-drilling screws made of stainless steel.

The cover layer 4 is further attached to the wall of the building from the edge of the rainwater gutter 2 further away so that the cover layer 4 is bent around said edge or the drip nozzle 6 therein.

The coating according to the invention is applied in such a way that the natural fiber mat forming the leveling layer 3 is initially applied, which can be fixed in place, for example by gluing, at suitable points in order to facilitate the work. The installation of the cover layer 4 is started by fixing the edge of the plate forming the cover layer 4 as high as possible under the roof 1 of the rainwater gutter 2 or the eaves strip. Self-drilling screws made of stainless steel are preferably used as fasteners 5. Thereafter, the top layer 4 is pressed and bent against simple leveling layer 3 using simple, preferably wooden or plastic press tools, according to the shape of the rainwater gutter 2 to be rehabilitated.

The top layer 4 is attached from the outer edge of the rainwater gutter 2 by bending the top layer 4 around said edge or the tip charge 6 therein.

To facilitate the installation of the coating, the end pieces (not shown) of the rainwater gutter 2 to be repaired are temporarily removed before the top layer 4 is applied. The top layer 4 is folded so that an end portion integral with the rest of the gutter part is provided for the chute 92512 5 formed by the top layer 4. The leveling layer 3 is then applied to the end part and the original or new end pieces are fastened.

What is essential in the coating according to the invention is that the top layer 4 forms a completely uniform, seamless trough. In the event of a possible blockage of the rain horn, water flows over the front edge of the gutter to the ground. Thus, at no point does the water come into contact with the inner surface 8 of the original gutter.
