Today, houses with a multi-gable roof have become quite common. Such buildings have a very original design. But not everyone will undertake to erect a multi-pliers design, since only special construction companies can do it. The cost of such services is quite high, so not every owner can afford to erect a similar design. However, the results exceed all expectations. Let's see what are the features of such a roof and how does it differ from others?
Features
A multi-gable roof is a rather complex structure, which includes many structural elements (ramps, tongs, ribs, valleys, etc.).
This type of roof is mainly used in the construction of houses with a complex polygonal shape, atypical layout, with a large number of rooms and where there are additional extensions to the building.
The construction of a multi-gable roof is quite expensive, since a lot of roofing material is needed, and after work a large amount of its waste remains. It is also recommended that you take care of the quality ventilation of the attic space and complete isolation from the heated rooms.
A multi-plated coating is formed due to the installation of several slopes and the creation of internal angles - valleys, along which the bulk of the atmospheric precipitation flows.
One of the disadvantages of this design is the complexity of its construction and the high cost of time and effort. This type of roof is most often found in the construction of private houses.
A multi-gable roof can be simple with two slopes or multi-sloping with several slopes.
Half-hip designs and two-level coatings are considered very popular today.
Benefits
Among the positive characteristics of multi-gable roofs can be distinguished:
- Unusual and very attractive appearance. The design can be completely different, depending on the parameters and functionality of the structure.
- High strength and reliability. This type of roof is able to withstand heavy loads on its surface without changing its original appearance.
- The durability of the structure, the life of which is unlimited. True, you need to consider that the material used and the design play a significant role here.
- Practicality. Thanks to the slopes, located at a large slope, precipitation does not accumulate on such roofs.
- Efficiency. The space under the roof can be used as you wish.
disadvantages
In addition to many advantages, a multi-gable roof also has certain disadvantages, which should also be remembered.
- The complexity of the construction of such structures associated with the presence of many elements (tongs, ramps, ribs, etc.). To perform such work requires training. If you are building a multi- gable roof with your own hands, in order to avoid mistakes during construction, you should consult with specialists in this field who will help in developing the roof project, tell you how to take into account the load of roofing materials on the rafter system, etc.
- A significant amount of construction and finishing materials waste, which, due to the fact that the multi-gable roof has a certain number of slopes, ribs, bends, etc., will be used irrationally.
Design Guidelines
1. The project of any house can be made using modern computer programs. It is not difficult, the main thing to consider:
- Parameters of the structure being built;
- The number of supporting structures;
- Roof loads, and what material will be used;
- The depth of the base.
2. You need to know what elements the roof consists of and the main features of its roof system.
3. It is necessary to correctly distribute the load of the bearing beams and rafters on the walls of the house, since it is they that guarantee the stability of the roof. It is important to understand that the smaller the distance between the rafters and beams, the stronger the roof.
Materials for building a house
Since the multi-gable roof has great loads on the building, experts advise building houses from strong and reliable materials:
- shell rock;
- brick;
- aerated concrete;
- foam block.
Sometimes wood is also used: rounded or profiled timber. Houses in such cases, to withstand the load of the roof, must have large dimensions and many load-bearing structures.
To increase the service life of the building, a number of works are underway to strengthen it. For example, the foundation of a house is initially strengthened. Ditches are dug around the perimeter of the finished base, concrete is poured using reinforcement. Bearing walls are reinforced with similar materials or special prefabricated metal structures that can be quickly and easily mounted on the internal and external corners of the structure.
Multi-gable roof: construction
For the proper preparation of the project of such a roofing structure , you should carefully study its structure. The construction consists of:
- inclined slopes;
- rafters;
- Mauerlat;
- crates;
- inclined and horizontal ribs;
- endows;
- skate;
- groove;
- gutter;
- overhang.
Multi-gable roof: rafter system
Since the design of such a roof is quite complex, special attention should be paid to its drawing. To do this, you must:
- measure all sizes;
- choose a slope for the roof;
- determine the type of rafter system;
- calculate rafters;
- to mark the location of the valleys, skates, ribs, vertical racks, puffs, runs, stops and other elements of the rafter system.
The basis of the rafter system of the multi-gable roof is Mauerlat. For its construction, bars are used, the size of which is 15x15 cm or 10x15 cm. Length is approximately 1.5 m. It is laid on top of a concrete or brick wall and looks like a connected rigid frame. Mauerlat is attached to the outer walls with galvanized metal studs mounted in an armored belt. Rafters (inclined or hanging) are made of boards, the cross section of which is 5x15 m. In the junction of the slopes, inclined and diagonal rafter legs are mounted . Since the main load will be directed specifically to the diagonal rafters, they should be strengthened with boards of the same size. On top of the rafters they are interconnected by a ridge, which you can buy ready-made or made of boards or timber yourself. On already installed rafters from the boards, a crate is mounted. To increase the strength and reliability of the design, the cells of the lathing are made no more than 50x50 cm.
Installation of multi-panel roofing
After the construction of the frame, they begin to isolate the structure. For these purposes, a simple plastic film is used, which is laid on the floors with an approach to the Mauerlat.
Depending on the type of roof finish chosen, a base is made. For example, sheet slate can be put directly on the crate. To mount a soft roof, you need sheets of OSB or plywood. They are mounted on the roofing frame, the material is laid on top. Warming and insulation of the structure in this case is made from the inside.
Many prefer metal tiles. But due to the low sound insulation, thermal conductivity and other disadvantages of this material, it will be necessary to conduct high-quality roof insulation.
