deposit any construction luck - the right design.
On how quality engineering conducted depends on how reliable the design.That is why, one of the most important parts of the house - the roof must be carefully worked out by specialists, even when you are going to build their own.
- choice of material for roofing
- Appearance roof
- Projects of houses with a flat roof
- Calculation of the roof
At this time, there are many companies that offer absolutely complete set of design documents requiredfor the construction of the roof, but not to be mistaken with the choice of the company, it is necessary to know what exactly it is necessary to pay special attention.
choice of material for roofing
One of the first things - the material from which the roof will be erected.If you can not see the "live", that is, in principle, suitable and photos - they will help the perception of the future appearance of the roof.
But, of course, not least the quality and functionality of the roof.Therefore, special attention should be paid to the material specifications:
- life.From it depends, how long the roof will serve without repair.And it depends on the strength of the material, its resistance to UV radiation and its ability to withstand any weather conditions;
- thermal conductivity.This is especially important for those who live in areas where very low temperatures are a common phenomenon.Of course, the amount of heat depends on the quality and quantity of insulation, roofing material but no less important.In this case, for example, a metal much inferior to natural.After all, this material not only protects against the cold, and shelter from the heat;
- noise.For example, when there is rain, bitumen and natural tile "behave" much quieter than, say, decking.
When you have decided on the material, it's time to think about how it will look like the roof of your future home.Of course, every owner very much that his home will certainly look better and more original than the others.But, choosing the original design, it should be clearly understood by virtue of whether you will build the roof.
Important! to be understood - the more complex the design, the more weight it has.Therefore, you must take this into account at the stage of foundations and erection of walls.
In general, the situation is - a simple design to build lighter weight it smaller, it costs less, but, of course, does not look so impressive.Nowadays, the most commonly used several types of roofs:
Most often used for outbuildings, as looks, frankly, not very attractive.In addition, this design eliminates the possibility of arrangement of the attic or attic, but with the successful design solutions like roof looks quite unusual.
Such roofs have two oppositely directed slope.They are used quite often as simple in construction, durable and provide additional space for storage in the form of lofts and housing - in the form of lofts.
These are some subspecies:
- one composed of four triangular rays and is a pyramid on a square or rectangular base;
- others - two triangular ramp, two hipped - this type is used to clear rectangular buildings;
- are hipped roof and a broken form.
Projects of houses with a flat roof
Particularly noteworthy flat roofs.They are not very common in our latitudes, but gradually, though, are gaining popularity.The advantages include:
- Creativity.As already mentioned, this type is not too common in our area, so the house is guaranteed, will look unusual, compared with the surrounding buildings.
- material benefit.This allows additional roof operation.This could be a summer playground for recreation, green area - sort of a roof garden, or even a miniature swimming pool, on the condition that walls and foundations are powerful enough.
- savings.Designing a flat roof cost is relatively cheap.
- Ambiguous advantage - "cumulative" capacity.This means that on the roof, in a natural way, going to the snow that is so myself further, insulation.
its shortcomings, of course, also have:
- complexity of installation.More precisely, even not the complexity and the need for strict and precise observance of technology installation.Because, otherwise, it turns the roof, which accumulates water - as a result, it flows.
- reverse side of snow accumulation.The snow collected on the roof, with a change in the weather, of course, will begin to melt, because it will be necessary to clean off his hand to the roof is not overloaded and does not leak.
Calculation of the roof
Calculation of the roof can be divided into three stages:
- calculation of roof system;
- payment cover;
- calculation fastenings.
When calculating lumber is taken into account - cross-section beams, presumably the weight of the whole structure of the roof, coating materials.To calculate the amount of the materials necessary to consider the future structure and size of the material, for example:
Depending on the type of roof truss system and, of course, different.How much the roof ramps will be dependent thickness suitable logs and boards, the amount of materials used and others.
Step stacking timber depends on the weight of the system and, in fact, a roofing material.The secondary load, but no less important, is the one posed by the snow.In addition, we must not forget about the weight of workers who not only erect the roof, but, over time, will make the necessary repairs.
calculation is so:
- at special tables - they can be used to calculate the maximum load on the beams rafters;
- the overall structure of the meter - this method allows you to calculate the required strength with a stock;
- along the length of the rafters - for the final result takes into account the total number;
- by the number of pairs of roof - they are distributed along the entire length of the roof.
