Faltsevy roof most

The material for a faltsevy roof is the metal which is let out in rolls or separate sheets. It got its name because of the method of joining the elements of the coating? faltsevogo method. When connecting with metal, bends form a special pattern by which it is easy to identify the method and material of the roof. The advantage of this method is the high tightness of the seams and the durability of the dock. This type of coverage is easy to install, and will last more than one decade.

What is the fold?

The seam is a seam connecting the parts of the roof, it is performed by bending the edge. By the number of bends, there is a standard single and double seam, characterized by greater tightness. The fold used for longitudinal joints is called standing, its height reaches 25 mm.

Horizontal joints are formed by a recumbent seam, it bends down to the plane of the flooring so as not to impede the flow of water. For rolling seams use a special hand tool, roofing frame or an electromechanical machine. There are also self-latching sheets and strips that make installation of a folded roof much easier.

Materials

Metal, characterized by the highest anti-corrosion characteristics, durability and attractiveness, it is copper. It will serve 100 years, remaining reliable protection of the building. Copper has only one drawback - high cost.

Zinc Titanium the lifetime is close to copper. Its plasticity allows you to create a roof of various shapes. Over the years, thanks to the patina layer, the resistance of the alloy to corrosion only increases.

Aluminum - light and rust resistant. It is easy to transport and stack. Priced more affordable than copper.

Galvanized steel It is made in rolls and sheets, it can have a colored polymer coating, which improves performance and makes the material attractive. Affordable cost makes steel popular for folding roof.

Foundation preparation

The small thickness of the metal requires a solid base to avoid bending under the weight of snow or under other loads. The basis is used frequent or continuous obreshetka. Before her device lay a layer of waterproofing material to protect against moisture and steam. The wooden base is made of bars, edged boards or moisture resistant plywood. The thinned crate is packed in 25 mm increments, which will save the coating from deflection during installation. On the eaves and endov always performed crate. Before mounting the wood is treated with antiseptic.

Instruments:

• workbench for making paintings (stripes);
• hammer;
• mallet;
• scissors for metal;
• tool for rolling seams.

Formation of paintings

Prior to mounting directly, pictures are prepared - strips or sheets with a profiled edge, that is, with edges bent under flange connection. The material is cut into pieces of the desired length and on the workbench, the side edges are bent with a hammer. On the one hand, at an angle of 90 degrees, and on the other, a double bend in the shape of the letter “P” is performed. The size of the paintings should be equal to the length of the slope. Ready to mount elements of the coating raised to the roof.

The rolls are rolled out directly on the crate, and the strips are fixed with a standing seam. The lack of horizontal connections makes this method more reliable, eliminating any leakage.

Mounting pictures to the crate

The folded roof begins to stack from the eaves upwards, from which side the installation begins, it does not matter. Preliminarily, a cornice strip is nailed to the crate with galvanized nails. The bottom picture lock should always remain for attaching the next sheet. Between the longitudinal seams the same distance is maintained, it should not be less than 40 cm. The pictures are fastened to the crate with clamps. This is a strip of galvanized steel, one end of it is screwed to the board with a self-tapping screw, and the other is folded up and secured when the seam is rolled. It turns out hermetic lock that does not violate the integrity of metal sheets. Stand-up joints are made single or double if increased strength is required. The roof with a slight slope of 7? 14 degrees requires additional sealing of the seams with silicone. Two types of clamp fastening are used:

• mobile, which compensates for the thermal expansion of the metal, and is set for bands of more than eight meters;
• motionless? for blanks of small length.

All longitudinal and horizontal seams are rolled up with a special device. Transverse recumbent seam as close as possible to the plane of the sheet, so as not to create an obstacle to flowing water.

When forming the ridge, the top of the paintings is bent by 25 mm. The ridge can be flat or shaped, it is fastened with self-tapping screws to the seam lock. Places of a junction of a roof to pipes and other obstacles, are closed by a wall profile which fastens to a pipe and a covering with self-tapping screws. All connections are treated with sealant.
