Rational and correct calculation of the roof

Today, the calculation of the roof is required in two cases: dismantling of ceilings in houses of the old type or the final works that are being carried out during the construction of a new house. Despite the fact that these cases are so different, the calculation system for them is the same, however, like the building materials used in this case.

It is worth noting that, reworking the old roof, neitherin any case it is impossible to erect it on the former analog. Firstly, this is a loss-making occupation, as the logs with which the roof was previously blocked are now extremely expensive. And secondly, the new technologies for building a rafter system are universal, they give a minimal load on the walls and foundation of any building.Calculation of the roof

So, if a house that needs a newoverlap, was built about forty years ago, then you can easily prepare a calculation of the roof, based on the mass of the wooden beam or planed board. These materials and will become the frame foundation of the new floor, as they are hardy, durable, yet light and perfectly manageable. An important factor is also the price of these wooden building materials. The beam refers to more expensive goods, and it is more difficult to lay it on the roof. But the standard board, which has a sufficient width, is an excellent alternative to any expensive material.

The calculation of the roof of a standard roof can bemade even an amateur in the issue of construction and repair. The scheme for the formation of load-bearing structures, to which the rafters are attached, is available on any construction site or in repair magazines. The main thing is to have all the necessary tools, the proper amount of building materials and wit. The roof, which is made from uneven bars or from a planed board, is assembled right on the site, so to knock down such a bulky construction, and then raise it upward will not have to.Calculation of the attic roof

More complex and uncommon will be the calculationmansard roof. Such a construction should be as strong and reliable as possible, and therefore the rafters are attached to their bases in a different way than when building an ordinary roof. The basis is the lag that is fixed on the walls. They are important not only to establish correctly and firmly, but also to connect with each other. Afterwards, in the intervals that formed between the lags, vertical stands are fixed, which will form the basis of the attic floor. They must also be fastened together, and if necessary reinforced with additional boards. Calculation of the roof mansard type is completed by installing rafters on the main structure, as well as skates and ramps.Calculation of the roof of the roof

Calculation of the roof, both standard and mansard,Also includes the installation of a crate. To do this, use the most thin and light boards. Then the roof itself is attached to them using ordinary slate nails or self-tapping screws. It is important to remember that the weight and other qualities of the roof can also affect the load that will be exerted on the building. It is desirable to choose the lightest finishing materials, but they must also have excellent thermal insulation and waterproofing qualities.
