Four-sheet roof has a characteristic design consisting of four planes. It does not have frontones, their place is occupied by a triangular shape of the skates. Such a roof is optimal for districts with strong winds and abundant precipitation. In the field of individual construction, it is most popular. The article will be told about how a four-piece roofing can be built with their own hands.

Four-sheet roof features

Before choosing the design of the roofing system, it is necessary to study its pros and cons. The advantages of the four-sheet roof are as follows.

1. Better than other structures withstand wind load.
2. It has high strength and resilience of deformation.
3. Overactions of the roof are mounted throughout the perimeter of the house, which makes it possible to effectively protect the walls from the rain.

The disadvantages of the four-sheet roof can also affect your choice.

1. Dorganiza of installation work and roofing materials. The area of \u200b\u200bthe four-page roof is greater than the duplex due to the lack of frontones.
2. The useful attic area is reduced, which could be used as a residential.
3. The need to install mansard windows (for inhabitants). Such windows are expensive and unreliable (their tightness is not guaranteed).

Basic information about the design of four-page roofing systems

Distinguish the following types of four-tie roofs.

1. Classical hip: represents the connection of two triangular and two trapezoid rods adjacent to the shortened skate bruus.
2. Tent: does not have a skate bar. Four equals along the length of the rafter are connected in the total vertex, and the details of the crates are attached to them.
3. Combined (sophisticated): There are valmo-fronttonal, half-haired, tambourine and multi-crossing.

Fundamentals of the fourth roof

Before starting the installation of the roof, you should be put on the place of Maurylalat. All parts of the system will rely on it.

The next step is the preparation of work drawings and the execution of the calculation.

How to calculate the four-page roof

Phased this process can be represented as follows.

1. A schematic drawing is compiled, which indicates all the main dimensions.
2. Determines the angle of linked all the rods of the roof.
3. The area of \u200b\u200ball rods of the tent roof is calculated (knowing the length of the base and the height of the triangle).
4. For the hollow roof, the area of \u200b\u200btrapezoidal skates is calculated multiplying the height of the trapezoid on the result of dividing for two amounts of bases.
5. Take into account the area of \u200b\u200bthe scenes.
6. By the amount of space, the amount of roofing material is determined.

Example of the drawing of the tent roof.

Calculation of roof

When constructing the roof, the rules are taken into account.

1. The setting step of the rafter depends on their length: 1.0 - 1.35 - for rafter feet to 3 m; 1.4 - 1.7 - for rafters in the range of 3 - 4 m; 1.1 - 1.35 - for rafted a length of 4.0 - 6.5 m; Over 6.5 m - 1.1 - 1.4 m.
2. For the tent roof, the block angle of the roof varies within 40 - 60 °, but adjusted: for the tiled roof, the slope must be 30 °, for slate - in the range of 14 - 60 °, for the roof, covered with flexible tiles - from 8 to 18 °.

Tip: You can use the services of online calculators to calculate the roof. Such services offer some Internet sites.

Stratets Description of the Installation Work

The technology of the structure of a four-page roof involves such a sequence of work.

1. Call rafters are installed. At the place of their compounds with Mauerlat (for hip roofs) or with each other, the racks are mounted.
2. Sound rafters (diagonal) are strengthened by naturines - short rafters, one end of which rests in Mauerlat (or the upper crown), and the other in the apparent rafters.
3. In the event that the length of the rafter rafters is significant, the installation of springs is needed (see the drawings of the four-sheet roof). They are based on tightening, especially for this, reinforced to Mauerlat or upper bars (for a log cabin).
4. For stiffness, the riggers, racks, saws are mounted.
5. The skiing timber is based on the overlap racks, and diagonal rafters and other parts are attached to the sink itself.
6. In order for the savory rafters and these focus to be securely attached to Mauerlat, use metal connecting parts or make scubs.
7. Private rafal elements are installed in 0.6 m increments.
8. In order to lengthen the roofing sv, to the lower part of the rafted rafters fasten the boards.
9. Horizontal details of the crates are attached to rafters with a step provided by the technology of the roofing material used.
10. Hydromaterial is stacked on top of the crates, vaporizolation is mounted.
11. The insulation is laid between the intermediate rafters (for example, mineral wool) with a layer with a thickness of 200-250 mm.
12. The roofing material is mounted.

Important: All wooden roof details must be treated with an antiseptic agent. In the event that the chimney passes through the attic, it is recommended to process nearby surfaces with antipirens.

Installation of riggers, racks and subposters

The device of the four-page roof is performed taking into account some nuances.

1. The angular rafters are installed at a smaller angle than the intermediate rafters. For their manufacture, a cross section of 150 × 50 mm are used.
2. The sloping slingery will be the same as the intermediate.
3. The skiing timber is made from the same boards that are used for rafters.

In conclusion - the installation of a four-page roof (video with explanations of a specialist).
