The rafter system with endovaya is an integral part of the roof of complex shape. There is a rafter system on each roof. Rafters are a structure made of beams, located under the slope of the vertical struts or inclined. The rafter is held on the so-called rafter legs, racks (which are held vertically on the structure) and, accordingly, the struts. They are connected with the help of subrafter beams, thanks to which the roof system provides the roof with protection for many years. That is Endova - a design whose task is to facilitate the flow of possible precipitation (snow, rain).
The rafter system of the hip roof.
The scheme of installation of rafters is performed according to the principle of butt or overlap. They are of several types: steel, wood and mixed. Most preferred rafters are made of wood due to individual technical characteristics. The loads that any roof system must withstand are temperature changes, strong wind, various precipitations, water vapor, as well as the effects of microorganisms and insects. This is a kind of bearing structure, so rain and hail have no effect on it (in this case, the roof protects). As for snow, such a system must withstand all its severity.
In places with numerous snowfalls, a truss system is installed with steeper slopes (the gap between the rafters is significantly reduced, and the angle is made sharper, as a rule, at least 30 °). However, snow does not pose a serious threat to the roof. As a rule, the presence of wind can damage the roof, which leads to its destruction. To avoid such consequences, you should make the roof base airtight and fix the roof on the base (to avoid blistering). Temperature changes can also destroy the roof or deform it (as any building material is modified, compressed or expanded under the influence of temperature). To avoid this, the expansion coefficients of all components of the system must be the same.
Negatively affects the roof system and water vapor. To protect wooden or metal elements will help vapor barrier film. At the end of the installation, any roof must be soaked with a special mortar so that various microorganisms do not damage the surface.
Endova open type.
The endova rafter system is available with hanging rafters or inclined. Each type has its advantages and disadvantages, as well as individual technical characteristics. For example, hanging type rafters have only 2 points of support, which are located on the walls of a house. Auxiliary elements, which keeps the design, are able to shrink and bend. Thus, the walls play the role of making a horizontal arching force. To reduce the force, wooden or metal fasteners are used, which serve as fasteners for the rafter legs. They are installed either on the basis of rafters, or above.
It is quite possible to make a truss system with your own hands. But during installation, it is necessary to take into account such criteria as the shape of the roof, the characteristics of the frame, the load on this system. To choose the right rafters step and the view, it is necessary to calculate the impact on the roof. This is done by experts in this field of work, but you can make the installation of the truss system yourself. Before installation, carefully consider all stages of work, it is desirable to make a plan. In addition, determine the type of system, materials and additional elements. The process of work itself takes a lot of time, but is not very complex.
It is easy to choose a material: the difference between wood and metal is small (both are conditioned by durability and strength), but it would be reasonable to use wood for rafters, since it is better treated and does not rust. For rafters use bar. Moreover, the length of this element is chosen exclusively along the length of the beam, the thickness of which should not be too large.
The presence of beams, fasteners and other additional details does not depend on the type of truss system - they all have the same design. Proper installation of their own hands is due to the presence of possible loads on the roof of the house. The reliability and durability of the roof will depend on the architecture of the truss system.
Roof insulation scheme in the valley of the valley.
You should not start work without first drawing up a plan - otherwise you will have to call in specialists to correct the defects and malfunctions. Thanks to the design, you will clearly represent the entire structure, its shape and general appearance, which will allow you to avoid trouble during work.
If the choice is to be made in the type of truss system, then it is important to pay attention to the particular design of the rafters. For example, a hanging type rafter is a set of additional elements that are necessary to evenly distribute the load on the roof. As for the inclined type, here the location of the rafter legs falls on their attachment along the installed bar.
Endova is the angle that forms at the junction of skates. It is the most important node in the entire roof system. Such a structural element of the roof is capable of accumulating precipitation, which are subsequently diverted into installed ramps. This node is more exposed to climatic influences. The purpose of the bottom endova slats is to protect the roof from water penetration. The top bar serves as an element of decor.
The first stage of the installation work is to fasten the batten.
If there is a bladder, then waterproofing should be installed.
This is done so that the space under the roof is protected from water.
Tools needed for work: a hammer, construction scissors, an electric drill, a hacksaw for metal and wood, a saw.
To work you need the following tools and materials:
Construction of inclined rafters.
To connect roofs with different heights, you need to measure the length of the valley and bend it closer to the edge of the roof. Thus, you create the necessary level of slope to protect the roof from moisture.
