Construction of the roofed roof - we weigh everything "for" and "against"
When constructing this roof, you can save money, because it does not need to build pediments. Such a roof can be trapezoidal, multi-sloping, domed, mansard and so on. The main factor in its installation is observance of symmetry.
The tented roof, the design of which has aerodynamic properties, will stand up even in direct squall winds, and also prevent cold air streams and moisture from entering the attic space. A lot of people find this type of roof attractive.
The tent roof also has drawbacks. For example, its design is considered one of the most difficult to design and erect. The area of the attic or attic floor is much smaller than with a gable roof, although this problem is partially solved by the mansard type of hip roof. This article will tell you how to make a tent roof.
Tent roof - do the right calculations
The construction of the tent roof with their own hands is not an easy task, but it is quite feasible with some knowledge and skills. It will require careful calculations. If there are any doubts, it is better to order a drawing for specialists.
The roof hood is calculated after the roof shape and the slope angle of the skates are determined. To do this, you need to know the base area and height. In most cases, at the base of such roofs is a square, and the rays are isosceles triangles.
The area of one ramp is calculated by multiplying its height by half the width, and multiplying the area of the ramp by four, you can get the total area of the roof, which will calculate the number of required materials.
Roof tent roof system consists of:
- diagonal rafters;
- Mauerlates;
- side and ridge runs;
- kukosin;
- diagonal elements, which are used to impart a rigidity design.
The construction of the tent roof begins with the installation of Mauerlats, which are attached to the previously aligned wall. If the wall is brick, it is necessary to lay a moisture-resistant layer under the Mauerlat. The construction of a tent roof involves the use of several types of rafters: diagonal, central and intermediate. The selection of the cross-section for the rafters should be made taking into account the loads that the hip roof will experience.
Tent roof with our own hands - get down to business
The installation of diagonal rafters is a very important task, since the straightness and evenness of the rajids' planes will depend on the correctness of this work. They diverge from the ridge beam to the corners of the house. Diagonal rafters constitute the framework of the entire structure. The central girders with the upper end are attached to the ridge beam, and the lower ones to the mauerlat. The step between them should be at least 60 cm, strictly opposite each other.
Intermediate rafters are joined with diagonal legs, and not with ridge bars. It is worth noting that often they are attached not perpendicularly, but at an angle. The strength of the entire structure will depend on the quality of the ends of the rafters and the joints, since the rafter can be displaced by improper adjustment and connection under the action of the ultimate load.
After the construction of the truss system, it is possible to insulate the roof, lay hydro and steam insulation, fill the crate and cover with roofing material. The installation of the hipped roof is completed, it remains to wait for the first precipitation to test it in practice.
