Roof multi-clasp: features and installation of a rafter frame

Today, houses with a multi-cliff roof began to meet quite often. Such buildings are very original design. But not everyone is going to erect a multi-clasp design, since only special construction companies can do this. The cost of such services is quite high, so not every owner can afford to erect such a construction. 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-cloak roof is a rather complex structure, which includes many structural elements (ramps, forceps, ribs, ends, etc.).

This kind of roofing is used mainly 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 the multi-cliff roof is quite expensive, since many roofing materials are needed, and after work a large amount of its waste remains. It is also recommended to take care of the quality ventilation of the attic space and complete isolation from the heated premises.

A multi-clot coating is formed due to the arrangement of several skates and the creation of internal corners - valleys, along which the main part of atmospheric precipitation flows.

One of the drawbacks of this design is the complexity of its construction and the large expenditure of forces and time. This type of roof is most often found in the construction of private houses.

The multi-clasp roof can be simple with two slopes or multi-slope with several slopes.

Today, semi-valley designs and two-level coverings are considered very popular.

Benefits

Among the positive characteristics of multi-clay roofs can be identified:

• Unusual and very attractive appearance. The design can be completely different, depending on the parameters and functionality of the building.
• High strength and reliability. This type of roof is able to withstand its surface large loads without changing its original appearance.
• Durability of the construction, the lifetime of which is unlimited. However, one must take into account that the material used and the design play a significant role here.
• Practicality. Due to the slopes, which are located under a large slope, precipitation does not accumulate on such roofs.
• Efficiency. The space under the roof can be used at your discretion.

disadvantages

In addition to many advantages, the multi-clasp roof also has certain drawbacks, which should also be remembered.

• The complexity of the erection of such structures, associated with the presence of a variety of elements (forceps, rays, ribs, etc.). To perform such work requires training. If you build a multi-cliff roof yourself , to avoid mistakes in the construction should get a consultation with experts in this area who will help in the design of the roof, tell how to take into account the load of roofing materials on the truss system, etc.
• A significant amount of waste construction and finishing materials, which, due to the fact that the roof multi-clasp has a certain number of ramps, ribs, bends, etc., will be used irrationally.

Recommendations for drawing up a design plan

1. The design of any house can be made with the help of modern computer programs. This is not difficult, the main thing to consider:

• Parameters of the erected structure;
• Number of bearing structures;
• Roof loads, and what material will be used;
• Depth of foundation.

2. It is necessary to know what elements make up the roof and the main features of its rafter system.

3. It is necessary to correctly distribute loads of load-bearing beams and rafters to the walls of the house, as they guarantee the stability of the roof. It is important to understand that the smaller the distance between rafters and beams, the stronger the roof.

Materials for building a house

Since the multi-clasp roof exerts great stress on the building, experts advise to build houses of strong and reliable materials:

• Shell rock;
• Bricks;
• Aerated concrete;
• Foam block.

Sometimes wood is used: cylindrical or profiled bar. Houses in such cases, to withstand the load of the roof, should have large dimensions and a multitude of supporting structures.

To increase the service life of the building, a number of works are carried out to strengthen it. For example, the foundation of the house is initially strengthened. Along the perimeter of the already prepared base digs out the ditches pour concrete using reinforcement. Bearing walls are reinforced with similar materials or special ready-made metal structures, which can be mounted quickly and simply on the inner and outer corners of the building.

Multi-hood roof: construction

For the proper design of such a roof structure , you should carefully study its structure. The structure consists of:

• Inclined rays;
• Rafters;
• Mauerlat;
• Crates;
• Inclined and horizontal ribs;
• Ends;
• Skate;
• Groove;
• Drainage;
• Overhang.

Multi-hood roof: rafter system

Since the construction of such a roof is quite complicated, special attention should be paid to its drawing. For this you need:

• Measure all sizes;
• Select the slope for the roof;
• Determine the type of rafter system;
• Calculate the rafters;
• Mark out the location of the valleys, skates, ribs, vertical racks, puffs, girders, stops and other elements of the rafter system.

The basis of the rafter system of the multi-clasp roof is Mauerlat. For its construction, bars measuring 15x15 cm or 10x15 cm are used. The length is about 1.5 m. It is laid along the top of a concrete or brick wall and looks like a tied rigid frame. To the outer walls of the Mauerlat is fastened with metal galvanized studs, mounted in armopoyas. Rafters (sloping or hanging) are made of boards, the cross section of which is 5x15 m. At the junction of the ramps, sloping and diagonal rafter legs are mounted . Since the main load is directed at the diagonal rafters, they should be reinforced with boards of the same size. From the top rafters are joined together by a skate, which you can buy already ready or made from boards or timber yourself. On the already installed rafters from the boards are mounted crate. To increase the strength and reliability of the design of the cell, the battens do not make more than 50x50 cm.

Arrangement of multi-panel roofing

After the construction of the frame begin to isolate the structure. For these purposes a simple polyethylene film is used, which is laid on the ceilings with a call to the Mauerlat.

Depending on the type of roof finish chosen, a base is made. For example, sheet slate can be placed directly on the crate. To mount a soft roof you need sheets of OSB or plywood. They are mounted on a roof frame, the material is placed on top. Warming and insulation of the structure in this case is made from the inside.

Many people prefer metal tiles. But due to low indicators of sound insulation, heat conductivity and other shortcomings of this material, it is necessary to conduct high-quality insulation of the roof.
