When you pass by the country plots, always pay attention to the variety of roofs. There are no forms here! Someone prefers simplicity and rigor, and somewhere, on the contrary, erect whole tent structures. Of course, the roof is important, and its role is determined not only by the external appearance, but also by the strength of the entire structure. For an apartment house it is better to choose a roof with a certain number of sides. The most common option is a gable roof. It makes it possible to give the house an identity, especially if the parties differ in size, angle or roofing material.
The construction of a gable roof directly depends on the type of rafters that are used in construction. Dampers are installed in those cases where, in addition to the outer walls, there are also intermediate supports made in the form of a wall or a column. Hanging rafters are laid on two walls. Any rafter structure is attached to the Mauerlat. Usually it is a bar that is used for masonry, or an upper log if the house is wooden. Thus, it is possible to distribute the load evenly over the entire area of the walls.
The rafter system of a gable roof with the same angle of inclination of the sides is an isosceles triangle. This geometric element allows you to give the necessary rigidity of the entire structure of the roof. Most often for rafters use a beam, the dimensions of which depend on the expected load. The material can be pine or spruce, as well as larch. Now there are rafter structures made of metal. The whole structure is fabricated in the factory, then delivered to the address and mounted on site without welding, which greatly simplifies the assembly.
In the upper part of the gable roof is fixed in the run, it joins the rafters and forms a horse. If it is necessary to give additional rigidity to the rafter system, then use a tightening, spreading or tuck. It is especially necessary to fix the rafters to the Mauerlat. Here you can use two types of connection. The rigid method allows to exclude any lateral displacement. The sliding joint has a lot of freedom and is used when the rafters hang over the wall, protecting it from rain.
To ensure that the gable roof does not cause you problems, it is better to invite experts who carefully calculate all the loads, based on the size of your house and other features. But you can do it yourself. Armed with tables and directories, you need to calculate the number of rafter legs, based on the thickness of the material and the distance between them. It should also take into account the length of spans and layout of the attic. The choice of roofing material can also affect the calculations.
The final version of how your gable roof will look, depends directly on the climate, the terrain, the amount of precipitation that fall at different times of the year, from what roof to be used, what tasks the building will carry, what materials the house will be built from and how much Money for construction will be spent.
