Rational and correct calculation of the roof

Today, the calculation of the roof is required in two cases: the dismantling of floors 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 unified, however, like the building materials used in this case.

It is worth noting that, by redoing the old roof, in no case can not build it on the former analog. Firstly, this unprofitable occupation, since the logs with which the roof was blocked earlier, 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.

So, if a house that needs a new floor has been built about forty years ago, then it is possible to prepare the calculation of the roof safely, proceeding from the mass of the wooden beam or the planed board. These materials and will be 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.

Calculation of the roof of a standard roof can be made even by a layman in the matter 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 plank, is assembled right on the site, so to knock down such a bulky construction, and then raise it upward will not have to.

More complicated and uncommon will be the calculation of the attic roof. Such a construction should be as strong and reliable as possible, and therefore the rafters are not attached to their bases in the same way as when building an ordinary roof. The basis is the lag that is fixed on the walls. It is important not only to establish them correctly and firmly, but also to connect them. 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, 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.
