Gable roof do it yourself

Independent installation of a gable roof is possible only with certain skills in working with such structures and implies increased attention to all details of construction procedures. To facilitate the implementation of the upcoming work will help you a careful study of our instructions, which describe in detail how the gable roof is made with his own hands, taking into account all the nuances of the operations performed in this process.

Roof options

In order to understand all the subtleties and peculiarities of the upcoming works, we will first introduce you to known types of gable roofs with different slopes of ramps, the choice of which should take into account the following factors:

• type of roofing;
• local climatic conditions;
• functional purpose of the structure.

The angle of slope of slopes in various buildings can vary in the range of values ​​from 10 to 40 degrees and significantly affects the choice of roofing material. In accordance with this indicator, gable structures can have the following versions:

• with gentle slopes (up to 20 degrees);
• roofs with a large angle of inclination (more than 20 degrees);
• roofs with a sloping sloping line (with a variable angle of inclination).

Preparatory activities

In order to determine the choice of the roof configuration optimal for your conditions, first of all it is necessary to take into account such an indicator as snow and wind load on it. Naturally, with a decrease in the angle of inclination of the roof, wind loads are noticeably reduced; however, in this case it becomes impossible to use the under-roof space for household needs (for an attic room, for example).

When choosing the form of a gable roof, it is usually assumed that the key support points of the truss system coincide with the lines of the location of the supporting structures of the structure itself (its upper floor, in particular). At the same time, the width of the house is taken into account, as well as the presence of internal load-bearing walls.

In preparing the project, the presence or absence of an attic room in the future structure, as well as the overall dimensions of the roof area, are taken into account. With a significant size of the closed area in the design of the truss system (in addition to the transom used as a carrier ceiling) should include additional elements - the so-called runs and racks.

It would be right to think about where the entrance to the attic will be, and if necessary to make a staircase.

When arranging a gable roof with your own hands (without an attic), it is allowed to use a system of inclined rafters that are attached with their upper part to the ridge girder. This run itself is supported, in turn, by special racks installed with support on the internal supporting partition.

The most practical and economical option for arranging roof structures, used mainly for lightweight buildings, are hanging rafters, while arranging them, the rafter legs are connected in pairs with the help of special bolts. The latter are horizontal jumpers that provide the required stiffness of the whole structure as a whole. Each of the hanging rafters rests at its ends on the side walls of the building.

In the event that its width exceeds 6 m, you will have to increase the number of installed runs and racks. Recall that the girder is a special horizontal bar used as an additional support for rafters and mounted using special racks.

These racks are based, in turn, on the so-called rods (pre-prepared timber laid along the slope). Such a timber together with racks can serve as a frame for the walls of the planned attic room. Thus, the use of naval rafters will allow you to equip the attic or a fairly spacious attic space used for household needs.

But before you make a gable roof, you first need to worry about the preparation of materials for it. When calculating the volume of the required lumber try not to overlook the fact that the weight of the truss system should not exceed the value for this construction. In this case, the section used for its arrangement of lumber, as a rule, is selected based on the size of the structure itself.

Reward

Mauerlat is used as a supporting base of the truss structure and provides its reliable and stable fixing on the walls of the building. As a mauerlat, generally used is a regular bar with a cross section of 100 × 150 mm, mounted around the entire perimeter of the building and ensuring an even distribution of the load on its walls.

Mounting a beam in the wall can be done in one of the following ways:

• special (rolled) wire used for fixing the support beam on the wall is brickled in the brickwork;
• metal studs of the required size (with a diameter of at least 12 mm) are immured into the masonry;
• a special monolithic concrete beam is made along the wall, equipped with steel studs.

The studs used for secure fastening of the mauerlat are located around the perimeter of the building with a pitch of about 120 mm. When choosing the height of the fastener, you should consider the total thickness of the waterproofing layer and timber with pre-prepared holes. During installation, the support bar is installed on the studs and is firmly fixed with nuts, equipped with wide washers.

Arrangement of truss system

The system of rafters of a typical house contains a number of parts that are structurally combined into a single whole. The main element of the gable roof is an A-shaped truss, which is a rigid structure that works on the principle of "on thrust". In the event that the frame of the house is made of timber - you should take care that its walls at the level of the ceiling beams are reinforced with special ties that exclude the possibility of their displacement under load.

On the ceiling on the side of the attic, special logs are laid (bars with a section of 150 × 150 mm), which serve as a support for the propeller racks. All repeating elements of the rafter system are made strictly according to the template, which allows to obtain an isosceles duo-pitch construction after assembly with an even distribution of weight loads.

A-shaped trusses for the truss system are assembled on the template directly on the ground, after which the prefabricated structure rises upwards onto the ceiling prepared for the installation of the truss. In this case, the girders are installed with support on the rails, and the rafters with their lower ends are mounted on the power plate.

At the same time, we note that in the manufacture of a truss template, you can arbitrarily change the length of its constituent elements by varying the parameters of the future roof (for example, its height). Thanks to this, you can choose the best option for your conditions.

At installation of rafter legs in places of their joining with strapping, special figured cut-offs are made to ensure reliable contact and a rigid bond with the power plate. To increase the rigidity of the structure in this mount is often used special metal plates.

Gable

When preparing a construction project (that is, before you build a house), you will need to carefully work out the arrangement of its gables.

Externally, the gable looks like a continuation of the wall, having a border along the line of the roof slopes. For the case of the gable roof we are considering, the gables have the shape of an isosceles triangle. The gable bases are extreme trusses, the height and verticality of which are strictly controlled.

In the upper part of the gable trusses is set the ridge girder, to which the rest of the rafters are subsequently attached. Sewing of pediments with boards is carried out in a pre-selected direction (vertically or horizontally). Usually it is organized upon completion of the entire complex of roofing works, but it is allowed to do this at the same time as the latter. With all the subtleties of mounting gable gables roofs you can familiarize yourself by viewing the corresponding video.

In conclusion, we note that both the gables and the elements of the roofing construction are subject to compulsory insulation.
