Fold a roof with their own hands
The folded cover is a surface of metal sheets, the connecting seam of which is formed by the special bending of the edges of roofing blanks. This type of mating allows you to get a fairly strong connection. The technique of making a folded roof with your own hands is somewhat different from the known methods of joining sheet blanks. In this case, instead of riveting or welding mechanisms, a special seaming machine is used, with the help of which it is possible to form an aesthetically attractive and fairly reliable connection.
Varieties of seam connections
The advantages of this method of arranging sheet coatings include:
- simplicity of laying sheet material, characterized by relatively low weight;
- the relatively low cost of sheet steel blanks;
- high quality and reliability of connecting seams.
All of the above advantages allow you to apply this technique of forming coatings in the repair of buildings of any profile, as well as in the manufacture of roofs in newly built houses. This method is especially popular in low-rise (private) construction.
We note in passing that when mounting the base, a classic “roofing pie” is prepared under the folded cover, incorporating elements of hydro, steam and heat insulation. At the same time, the roofing material itself, cut and laid out in the form of strips of coiled steel, has a decorative polymer coating, giving it a color range.
Steel billets are laid on the roof sheathing by pre-measured longitudinal strips, which may not always be solid. For the quality joining of individual strips of flooring, a special type of connection is used - the so-called “recumbent” fold, which has a flat shape and is hardly noticeable against the background of the coating.
Note that the longitudinal edges of the blanks are connected by the method of standing seam (see figure), forming a complex convex shape. Notice also that in addition to the standard single connection can be used locks with a more complex double fold.
Independent installation
To prepare any of the above compounds, you will need a special mechanism - the so-called machine for rolling the fold. " We do not even recommend trying to replace it with any self-made device (or other improvised means), which, if used, may violate the technology of formation of the seam and, as a result, reduce the quality and reliability of the joints formed.
If it is impossible (or unwilling) to purchase a machine for rolling seams, you can use a roofing set with already formed edges that provide a self-locking fold lock. The latter consists of the so-called “locking tooth”, which, when applying one metal strip to another, is easily captured by the hook-shaped profile on it. To get a reliable connection, you just need to snap the lock, which usually takes very little time.
The use of ready (molded) roofing material greatly simplifies the installation of the coating, as well as significantly reduces the time of construction work. For the arrangement of a folded roof besides the machine, the following tool kit is required:
- screwdriver, metal shears;
- pincers, mallet and hammer;
- a special gun for sealing seams with a sealant.
Installation Features
At arrangement of a faltsevy roof it is necessary to consider the following features of the organization of installation works:
- Regardless of the chosen method of joining sheet blanks, they are fixed to the sheathing by means of special clamping fasteners, a feature of which is their absolute invisibility.
- When mounting, each of the stacked panels must face its lower lock in the direction of the next element.
In the construction used 2 types of clamping fasteners: mobile and stationary. Movable mount is used when working with sheets longer than 8 meters, and fixed - for relatively short sheets. The structure of these mounts also includes a standard screw complete with press washer.
Roof decking is laid from bottom to top with a fixed distance between the longitudinal joints. It does not matter which side of the roof to start installation; The main thing to pay attention to is the correct orientation of the lower lock.
