Gambrel or hipped roof with his hands

gambrel or hipped roof - one of the most popular choices of roofing in the construction of individual housing in the world.

Unlike the gable roof of the house, which are mounted on the sides of the gables, hipped has additional ramps to form a triangle.

hipped roof with his hands is very difficult to perform, and if you are interested in how to make a hip roof, in the beginning you should definitely familiarize yourself with the theoretical part.

Before use all carefully calculated to make drawings and a project in which you need to specify the location of the various elements and other design features.

Design hipped roof

Calculation hipped roof and the projectIt must take into account all of the loads that will have an impact on construction.

design must be very strong, to resist strong winds, snow and other weather conditions.On how correctly to be picked up by the material of the roof also depends its life.

That's why creating a project and drawings, it is very important to correctly calculate all.Project hipped roof in the photo:

Before you create a project and drawing hipped roof of the house, you need to first figure out the angle of inclination of ramps, which depends on many factors such as the purpose of the attic, the roof material selection, as well as features of atmospheric influences.

The most common individual houses roof inclination angle is from 5 to 60 degrees.

If your local rainfall and wind do not differ a great force, the design of the inclination angle at the same time can be significant.

If in your area are often heavy rains and snowfall in the winter, the angle of hipped roofs of houses should be from 40-45 and up to 60 degrees.

From option, which is the angle of inclination is at the design also depends on the material finish, and features mounting:

• if the inclination angle is less than 18 degrees to the roof using corrugated and flat slate and roll materials for the roof;
• when the angle to 30 degrees, typically used species tile;
• roof, slope angle which is not less than 30 degrees, use the usual piece goods.

Project and design calculation should take into account, which will be located all the elements of the roofing system.When you have determined the angle of slope hipped roof, you need to also calculate the height of the ridge.

hipped roof Rafter system

Roof installation of this type of private homes involves implementation of calculating the appropriate section of the rafters.The calculation is made based on the load, which will receive your hipped roof.

calculations, as well as construction project should include wind load, the maximum possible mass of snow in winter, the angle of inclination of the roof.

When calculating the distance between the rafters need to assess their ability to withstand the load, as well as supply of their strength, which should be equal to 1.4 and more.

Device type truss system depends on the features of construction, and therefore may be different.

If there is a bearing wall or the support of the pillars, that are commonly used naslonnye rafters, if the support unit is not possible, then in that case make hanging rafters.

both types of trusses used in some buildings at the same time.

Through drawing and project the future of construction, it is important not only to determine the type of roof system, but also take into account the additional elements of fixture, which will give the structural strength and reduce the load on the beam.

Calculation roof loads

drawing and designing individual houses roofing project, it is important to calculate the load.

loads are such types:

• constant - the weight of the insulation material, a variety of materials and finishes insulation,
• weight materials for the roof and the weight of the crates;
• time - the weight of snow in winter, the negative impact of the wind;
• additional - different designs, which are fixed to the roof.

creating design and drawing of the roof of your house, you should stick to the average value of the snow load, which is equal to 180 kg per sq.m.

But if the inclination angle is 60 degrees or more, the snow load is not taken into account.

With regard to wind loads and their average value is usually 35 kg per square meters, but if the roof slope less than 30 degrees, this amendment does not take into account.

should also calculate the weight of the additional load, the role of which can act as air chambers, water tanks and other structures, which are located in the attic.

Before starting work, should also calculate the strength of the structure and the possible extent of deformation of various elements of the roof.

Calculate it can own, but you can take advantage of special programs, calculators to help you calculate these parameters.

After making all calculations can proceed to the choice of material for roofing.

The photo below shows the structure diagram of a hipped roof and the name of all the design elements.

choice of materials for the construction of the roof

When the area is covered with a hipped roof roofing material, there is a lot of waste.

Therefore, to cover the area of ​​the hipped roof, usually chosen such roofing materials, elements of which are small.

The most common materials for the roofing areas are flexible or regular tiles, slate sheet, Ondulin, metal.

To build a roof that will last for decades, you need to pay special attention to the selection of materials for the roof system.

Typically, the construction of hipped roofs use lumber from softwood tree.

Do not neglect the quality of wood, choose a material without defects, which can further reduce the quality and durability.

important criterion for the choice of timber is its moisture content, which must not exceed 15 - 20%.

If this figure is exceeded, the timber must be dried before use, then that during the service hipped roof is not distorted and deformed.

device rafters for the roof of the house is usually carried out using a rectangular beam cross section which in each case should be calculated.

To construct such a construction, commonly used board with a rectangular cross section of 50 to 100, 50 200, 100 150 and others.

If you need to, in the course of work can geminate board to obtain the desired diameter.

to build a hipped roof, often used special steel elements that firmly hold the rafters in the same position for many years.

Furthermore, the support for the ridge also runs often made of metal.

Construction hipped roof

All wooden parts for the roof frame is treated with a special compound, which will save from the fire tree.In places where the timber will be adjacent to the brick or stone, you need to wrap it in waterproofing.

Start device hipped roof with paving around the perimeter of the roof area of ​​the building mauerlat.

mount it using wire loops or hairpins, which are embedded in the wall or in the floor slab.Next, set the central beam, which is located on the central axis of the house.

It should be based on the floor slab and the inner wall.

To design was totally symmetrical, it is important to calculate and mark the location of the diagonal trusses and the ridge support.

ridge height should also be marked with the maximum precision.

clear symmetrical design layout make uniform load distribution and prevent distortion of the roof in the future.

Once the perimeter of the roof area was set mauerlat, put beams under the ridge pole.The height of the ridge must strictly comply with the design drawings.

ridge beam To further secure the diagonal beams, which use a dual beam or plank.

diagonal beams to withstand high loads during service, so they need to be set very accurately.

If the length of the beam or board is missing, the diagonal support is made of two parts.To splice site did not experience the ultimate load, install a support beam under it.

most rigid construction can be done, if you place the joint with a support at such a distance that is equal to the fourth part of the length of the rafter beams from its upper edge, which is attached to the ridge.

is best device diagonal trusses accomplished through the legs of prefabricated trusses for which it is convenient to mount.The installation of diagonal trusses you can see in the video.

Next comes the installation of rafters for the crates.

device involves installation of the roof trusses are not only full-length, which is connected to the ridge, but also those that are attached to the diagonal beams - narozhnikov.

closer to the corner of the house, the shorter narozhniki.

distance between the rafters is also determined during the development of the roof project, but it should be borne in mind that each ramp should have a minimum of three central truss beams.

To make the design maximum rigidity where needed secure the supports, bracing and tightening.Scheme fixing rafters can be seen in the photo.

The final step is the roof of the device mounting batten rafter.Typically used timber battens measuring 50 by 50 mm.Step battens depends on what kind of roofing material you choose.

Then the whole area is fixed waterproofing and roofing material, and the inside of the entire area is attached vapor barrier and insulation.

If the attic area to be used as a living room, you should also install ventilation.

Next hipped roof area covered with roofing material, to which it is attached with screws to the crate.Then set the horse, which spans the distance between the ramps.

Today, all manufacturers of roofing materials also offer the ridge parts of the same textures and colors.

On hipped roof establish the main horse, and horses, which cover the gaps between the main slopes and hips.

Rounding out the installation of a hipped roof installation of eaves and gutters.The entire process is shown in the video.
