The construction of a gable roof system

The gable roof system has a fairly simple device, its installation does not take much time and can be successfully produced by hand.

Gable roof can be found quite often, and this is due primarily to the fact that for the home this design is the best option, able to effectively protect against various external influences.

The design and construction of such a roof is relatively simple, and with the right approach to business and minimal building knowledge, you can do it yourself without any problems.

Installation and assembly of the roof, consisting of two ramps, does not take much time, and besides, it does not require serious money costs.

There are different roofing options with two slopes and depending on which house design is planned, a drawing is drawn up and the corresponding calculation is made.

The gable roof allows the construction of additional living space in the form of an attic.

Its design can be hanging, nylon, in the form of a broken line, and also has a very different configuration.

In the photo in the article you can see different types of gable roofs, including those with an attic.

truss system Design features of the

rafter system A characteristic feature of any gable roof is the two oblique rectangular planes that it forms intop of the house.

Such a device allows different types of precipitation not to accumulate and drain from it naturally.

Despite the apparent simplicity of such a roof, its design has a fairly complex device, but to do it yourself with the power of every hardworking person.

Variants of rafters

Its main structural elements are the Mauerlat, the truss system itself, the filly.

In addition, the project must necessarily include such types of elements as overhang, cut, as well as struts and puffs.

Also, the scheme of a gable roof provides for the arrangement of the crate and the implementation of racks.

The rafters themselves rely mainly on the Mauerlat, which is responsible for distributing the load from the truss frame to the walls.

Direct formation of the main frame is made at the expense of the rafter.

Both skates, which are formed by this type of roof, are joined together by a ridge, which is the end of all rafters.

Structure of the gable roof

The entire vertical load of the rafter system on the inner walls of the house is transferred through the racks for which a separate calculation is made.

For the transfer of loads directly from the rafters to the bearing walls, the struts that must necessarily be included in the project are responsible.

To ensure that the rafters are securely fastened together, a special tightening is arranged.

The main fastening element of the rafter structure is the crate, which is also responsible for the uniform distribution of external loads over it.

For the roof structure of any type of roof, it is important to have a preliminary calculation, on the basis of which a design is drawn up, which can also provide for the attic.

For a broken roof with two ramps, its scheme is provided, and a separate project is being developed.

In the photos below, the variants of gable roofs with a different slope for a private house are shown, which can be mounted manually.

Types of rafters

Any gable roof can have a rafter system, either with hanging rafters, or with struts.

The most optimal and reliable option for a home is a combined design that combines a combined combination.

Despite this, the types and ways of arranging the rafters are selected, based on certain design features of the house.

So, in most cases, the installation of a suspended type of rafters is performed when the outer walls of the house are located from each other at a distance of less than ten meters.

In addition, in this case, the house design should not provide for other internal separation walls.

Hanging construction of the rafters has a load on the walls of a bursting type, which can adversely affect the structure as a whole.

It can be reduced only if you mount a special wooden or metal assembly directly at the base of the rafters.

In turn, the installation of rafters of a built-up structure implies the installation of a special support beam, which must be done in the middle of the house.

This beam allows the weight of the entire roof to be evenly distributed on the columnar intermediate supports or on the middle wall, if the project provides for it.

In most cases, the nylon type roofing system is performed when the outer walls are at a distance of more than ten meters from each other.

Regardless of which type of truss system is selected for a gable roof, you need to perform a calculation that will evenly distribute loads across all the beams.

The main advantage of this rafter system is the possibility to equip the living room of the attic.

When choosing the type of roof for many, the most important factor is the price, in which case the gable roof has an optimal price-quality ratio.

In addition, the roof of an inclined type has an attractive appearance, as can be seen if you look at the photo.

Preliminary calculation of the roof structure

Calculation of the roof with two slopes with your own hands should begin with the choice of the material that will act as a roof, as well as some architectural requirements that are imposed on this type of roof.

It should be remembered that for a broken roof and with an attic, the calculation is slightly different.

First of all, it is necessary to take into account that the slope of such a roof, including a broken line, should be at least five degrees.

Dependence of the area on the slope

If the construction of the house is carried out on the terrain on which the abundant rainfall falls during the year, the recommended roof slope, including the broken line, should be on average forty degrees.

Of course, at this angle, the construction of the attic will become impossible, but the arrangement of a broken roof will help to solve the problem.

In general, the construction of the broken roof makes it possible to equip an additional room in the form of an attic.

If strong winds are observed in the region, it is recommended that the roof be sloping, with a slope of up to twenty degrees.

The most preferred option for the construction of a gable roof is the medium slope variant, in which the roof is not necessary to make a broken line and at the same time it is possible to equip it with a mansard.

It should also be remembered that installing such a roof with a large slope dramatically increases the cost of installing a wooden rafter frame.

In general, self-calculation should be done taking into account all the requirements, both external and internal.

The roof with a slight slope and two slopes can be seen in the photo, which is located below.

In order to purchase all necessary material in sufficient quantities, it is necessary to calculate the area of ​​the entire roof structure.

To do this, take the average area of ​​one ramp and double it. Typically, the total length of the ramp is approximately equal to the length of the wall.

This calculation should be carried out with maximum accuracy, taking into account all the necessary nuances.

The video, which is placed below, tells how to make a roof rafter system with two skates with your own hands.

Determination of loads for the

rafter system An important consideration in the design of the roofing system with two skates is the calculation of all loads, as well as the characteristics of the elements included in its structure.

In the case when it is planned to build a house in one floor, then to calculate the rafter system you need to know only two values, namely, directly the weight of the roof and the strength of precipitation and wind.

The weight of the roof is obtained due to the addition of the weight of each of the elements entering into the structure of the skates.

To find the expected load from wind and external precipitation, it is necessary to multiply the weight of the roof by ten percent.

In the event that the increase in the angle of inclination of the rajids is planned over time, then in the calculation carried out, a certain reserve for the loadings of the rafter system must be laid.

Mounting to the Mauerlat

The load on the truss system from the attic must also be taken into account.

All these quantities play an important role in the design of the rafter system, and therefore must be produced with the utmost precision.

To calculate the load of rafters from various external factors such as wind, snow, rain and so on, it is necessary to take into account all the climatic features of the area where the house is being built.

In this case, it is necessary to take into account the angle of inclination of the rafters. For example, if the rafters form a slope of skates at twenty-five degrees, then the snow load should be taken as one.

With a larger slope of rafters, the correction factor increases accordingly.

When carrying out the calculations, it must be remembered that from the rafter system, the load enters the walls, which are located along the perimeter of the structure.

Accordingly, all the parameters of the walls should also be taken into account when calculating the truss system at home.

Installation of rafters for a roof with two skates starts only after all necessary calculations have been made.

The video, which is located below, tells how to start the construction of the roof truss system with your own hands.

Stages of construction of the roofing system

The installation of a double-skinned roof with your own hands should begin with the arrangement of the Mauerlat along the entire perimeter of the walls. To do this, use a quality wooden beam without defects.

It may also be necessary to build a special reinforcing belt, which will only give the strength of the roof with two skates.

The beams under the Mauerlat are laid on the upper end of the wall and fixed with a wire fixed in the walls.

Next, fix all the rafter feet.

Mounting of rafter legs should be made only from high-quality material, which is completely free of any defects.

In order to perform the work it was more convenient, it is necessary to make a pattern of the rafter leg, in which all the elements will be made in the future.

Next, the rafters and the rafter legs themselves are installed. More details on how to collect your own hands the rafter legs for a roof with two skates, is described in the video below.

When assembling a rafter structure for a roof with two slopes, it is necessary to withstand the specified step between all the beams as accurately as possible.

After the installation of the entire truss system is complete, it is necessary to fix the skate at the top edge.

Then follows the construction of the roof on two slopes qualitatively to expand, in order to give it maximum rigidity. To do this, use special tightening torques and bolts.

In certain individual cases it may be necessary to erect fastening beams. In any case, the design should not only be strong, but also tough.

At the final stage, the roof crate with two skates is executed and how to do it correctly is told on the video.

The lining is made taking into account the characteristics of the roof, which will be laid on top of it. After that, it remains only to make a roofing cake and put the roof itself.

It should be remembered that the roofing pie must necessarily consist of a layer of waterproofing, vapor barrier, as well as a heater.

Installation of the roof truss structure with two slopes must be carried out in accordance with the technology and in accordance with established rules.

Use only high-quality wood as a material, which does not contain any defects.

Special attention should be paid to imparting strength and rigidity to the entire structure of the rafter system.

Also important is the roof lathing, which must be done taking into account all the characteristics of the roofing material.
