Formed sheet metal (100), in particular eaves flashing, for direct installation, comprising: - a flat rolled metal product; characterized in that - a primer is applied to one side, in particular the outside (110, 120, 130), of the flat rolled finished product.

Description

[0001] The present invention relates to a shaped sheet, in particular a eaves sheet, with a primer.

[0002] Shaped sheets, such as eaves sheets, are well known and are used in various trades, such as roofing.

[0003] Typically, the formed sheet metal is delivered from the factory without any paint, meaning that the formed sheet metal must be made ready for its intended use on site, for example by cleaning, priming, sanding and painting.

[0004] In the case of an eaves flashing, this also means that in addition to the sheet, a bucket containing approximately 20kg of paint or more must be brought onto the roof in order to provide the eaves flashing with the appropriate eaves flashing paint.

[0005] The coatings used for such work also include bitumen or other tough plastics that are difficult to process, making the installation of a flashing strenuous and time-consuming.

[0006] The present invention is intended to address at least one of the above-mentioned problems. In particular, it is intended to provide a shaped sheet, preferably a eaves flashing, that allows for quick and uncomplicated installation on a construction site. Alternatively, it is intended to improve the known prior art.

[0007] According to the invention, a shaped sheet, preferably a gutter sheet, for direct installation is proposed, comprising a flat rolled finished product made of metal, wherein a primer is applied or has already been applied to one side, in particular the top side, of the flat rolled finished product.

[0008] The proposed solution is a shaped sheet, particularly in the form of a flashing, that is already coated with an appropriate primer, particularly in such a way that the sheet no longer needs to be coated on site. This allows the shaped sheet to be installed directly on site, eliminating the need to lug heavy buckets of paint and / or laboriously prepare the shaped sheet.

[0009] A formed sheet metal is understood here in particular to mean a shaped sheet metal, i.e., a workpiece with a specific shape that is produced by a manufacturing process, namely: forming. During forming, it is essential that the material (metal) is neither added nor removed—the mass remains the same.

[0010] A sheet is, in particular, a rolled metal product that is delivered as a plate and whose width and length are much greater than its thickness.

[0011] Preferably, the shaped sheet is designed in particular as a so-called eaves sheet.

[0012] An eave flashing is designed to form the transition from a roof edge to a gutter. It reliably drains rainwater and meltwater, thus protecting a house's structure from moisture and humidity.

[0013] The eaves sheet is preferably made of metal, for example titanium zinc, copper, aluminum or galvanized steel.

[0014] Preferably, the shaped sheet is already coated with a primer. This means, in particular, that the shaped sheet is delivered from the factory with a coating already applied.

[0015] The primer is preferably used for sealing and / or as an adhesion promoter.

[0016] Preferably, the primer comprises bitumen and / or a liquid plastic designed to seal the transition between a roof edge and a gutter.

[0017] Preferably, the pre-coating comprises a coating material, such as a varnish, and / or a primer.

[0018] Preferably, the primer is applied to at least 80% of an outer side of the formed sheet.

[0019] Preferably, the primer is applied over the entire surface of the outer side of the sheet, in particular between 80% and 100% of the outer side, preferably more than 90%, further preferably more than 95%.

[0020] Alternatively or additionally, the primer can also be applied over the entire surface on one side and / or both sides.

[0021] Preferably, the primer can be activated, for example by adding another substance or a specific component or by heating.

[0022] Preferably, the primer can be activated or made flowable by heating it, for example to 100°C, 200°C, or more. This can be done on site, for example, using a burner or similar device.

[0023] In order to make the primer ready for use, it is therefore proposed in particular to heat the primer or alternatively to treat it with a component, in particular in such a way that the primer becomes soft to flowable.

[0024] Preferably, the primer is covered with a film.

[0025] The film serves in particular to protect the primer, for example from damage and / or drying out.

[0026] The shaped sheet is preferably designed as an eaves sheet.

[0027] Preferably, the flat rolled mill finished product has a bend in order to adapt the flat rolled mill finished product to a roof pitch.

[0028] Preferably, the flat rolled mill finished product has a fold.

[0029] A formed sheet proposed herein can be manufactured, for example, by the steps of: rolling a metal into a sheet; forming the sheet into an eaves sheet; and applying a primer to an outer side of the sheet.

[0030] Depending on the design, the eaves flashing can first be formed and then coated with the primer, or the other way around.

[0031] The primer is preferably applied to the sheet using a coil coating process.

[0032] Further preferably, a primer is also applied to the sheet metal, especially before the undercoat is applied. The primer is preferably applied to the sheet metal using a coil coating process.

[0033] In addition, in a final step, the primer can be covered with a film or similar.

[0034] The shaped sheet metal produced in this way can then be sold or brought to a construction site, preferably for direct installation – especially without applying a coating or primer on site. Therefore, the application of the coating or primer to the eaves flashing does not take place on the roof or at the construction site.

[0035] The present invention is explained in more detail below with reference to the accompanying figures, wherein the same reference numerals are used for identical or similar components or assemblies. Fig. 1 shows a shaped sheet. Fig. 2 shows an eaves flashing in an installed state. Fig. 3 shows a eaves flashing with primer.

[0036] Fig. 1 shows a shaped sheet 100.

[0037] The shaped sheet 100 is designed in particular as a so-called eaves sheet 100.

[0038] The eaves sheet 100 is essentially formed from a flat rolled finished product made of metal and has an outer side 100a, an inner side 100i and two kinks A, B.

[0039] The bends A, B at the angles α, β result in the special shape of the eaves sheet 100 with the three outward-facing surfaces: top side 110, front side 120 and bend side 130.

[0040] The top side 110 is designed to be installed on the roof of a house, as shown in Fig. 2 shown.

[0041] The angles α and β depend on the pitch of the respective roof and the intended use of the eaves flashing 100. The angle α is typically between 80° and 150°, and the angle β between 10° and 70°. The bending side 130 is therefore particularly directed inward.

[0042] The eaves flashing 100 can also have a fold 140 on the top side 110. Depending on the design, the eaves flashing can also have additional creases and / or folds.

[0043] The dimensions of the 100 mm eaves flashing—i.e., the width b, the depth t, the height h, and the bend height—depend primarily on its intended use. For example, the eaves flashing is 200 mm wide, 65 mm deep, 40 mm high, and has an inward bend of 15 mm.

[0044] Fig. 2 shows a eaves sheet, in particular as in Fig. 1 and / or Fig. 3 shown in an installed state on a house 1000.

[0045] The House 1000 (in Fig. 2 shown schematically from the side) comprises at least one dam barrier 1090, a wall 1200 and a roof 1300.

[0046] On the roof 1300 there is also a gutter iron 1400 which accommodates a gutter 1500.

[0047] The eaves sheet 100 is mounted on the roof 1300 by means of a fastening means 2000, for example a nail or screw, in particular such that the upper side 110 of the eaves sheet 110 rests on the roof 1300.

[0048] Finally, the roof 1300 is covered with roof shingles 1600. The eaves flashing 100 is therefore positioned between the dam barrier 1090 and the roof shingles 1600.

[0049] Fig. 3 shows a eaves sheet 100, in particular as in Fig. 1 shown, including primer 200.

[0050] In this embodiment, the eaves flashing is provided with a primer on the top side 110 and on the front side 120 over its entire surface.

[0051] In a further embodiment, the folded side 130 can also be provided with a primer on the outside. This is particularly advantageous for the production of the eaves flashing 100. In this case, during the production of the eaves flashing 1000, the initially flat rolled finished product can be completely primed on one side (the future outer side) and then subsequently bent to form the actual eaves flashing 100.
