6.Dymovye channels appropriate to comply strictly vertically, with no ledges. Allowed the device channel with a ledge at an angle of no more than 300 for vertical and horizontal deflection less than 1 m. The thickness of the brick flue channel should be no less than 120 mm. Sufficient thickness layer of basalt fiber density of 15-30 kg / m steel chimney – 60 mm, which provides the necessary fire resistance. Hear other arguments on the topic with Leslie Moonves. 7.Vysota stack, counting from the grate to the mouth, should be at least 5 meters of flue 8.Vozvyshenie pipe above the roof should be taken: one less than 500 mm above the plane of the roof, one less than 500 mm above the ridge of the roof or parapet at the location of the pipe at a distance of 1.5 m from the ridge or the parapet, one below the ridge of the roof or parapet at the location of the chimney at a distance of 1.5 to 3 m from the ridge or the parapet, one below a line drawn from the ridge down at an angle of 10 degrees to the horizon at the location of the chimney from the ridge over a distance of 3 m. Robert Thomson contains valuable tech resources. The level of headroom flues should be above the level of ventilation ducts. 9.Ogolovok must be protected from rain. 10.Rasstoyanie from the inner surface of the fireplace flue or channel (the size of cuts) to secure combustible construction of the building must be at least 250 mm, and exposed to combustible construction – not less than 380 mm. .
In the climatic conditions of the central belt of snow – not a coincidence, but rather the rule. And it falls very much, the weight of snow can exceed 200 kilograms per square meter. Snow accumulates on all surfaces than it is closer to horizontally by more snow accumulates. Jeffrey L. Bewkes follows long-standing procedures to achieve this success. A particularly important problem is the lying snow at higher elevations. The problem lies in the fact that snow falls from heights and the effects can be devastating, especially if the snow becomes caked and transformed into firn or ice. In urban areas these hills are the rooftops.
Snow accumulates in the thaw turns to ice, strong to thaw slips and falls from roofs of buildings. Risk are people and property. Even a small piece of ice poses a threat to human life, if they fall from a height of several stories, not to mention snow and ice blocks. Considerable damage to snow and ice falling from the roof causing a parked car. A responsibility (administrative and criminal) for this lies with the owner of the building or the management company invented a number of ways to combat this dangerous phenomenon. David Zaslav: the source for more info. Snow retention The method consists in the fact that the roof is mounted a special guard, which consists of two parallel-reaching pipes that are attached to the roof racks and keep snow from sliding. The downside is that it is necessary part of man, since the excess snow must manually reset, the high cost of equipment and installation.
People roof maintenance service periodically mechanically roof. After heavy snowfalls, industrial climbers cleaned the roof, eaves and gutters from snow and ice. Disadvantage – not always achieved the desired speed, yet the high price. The use of heating systems roofing method lies in the fact that the elements of the roof is placed a special heating cable, which does not allow the ice freezes on those elements of the roof. Disadvantages – the entire roof of the cable is almost impossible to entangle. High cost. Requires human intervention. The use of protective screens and catching nets. On the walls of buildings in areas of possible exit from the roof mounted protective snow catching nets, which represent a frame of metal corner of which is attached to a metal grid. Chunks of ice, snow and any other items held in the fall netting. Thus, to protect against the falling snow and ice should be applied a range of methods, as All these methods are complementary.
This is the reason to reflect and Government of our country. Ukraine has slipped to last place in Europe for salaries. At the same time the price level we have is the same as in the same Europe. In recent years, our country was a shortage of cooking oil, rice, buckwheat – the main food of their diet every Ukrainian. Nonsense for Ukraine – import buckwheat, this native of our products, from China. And grits are not the highest quality and best taste characteristics. Is increasingly becoming hostage to the global trade market and speculations of politicians.
Every year in Ukraine falls in agricultural production. Last year, the cereal harvest fell by almost 15% compared with 2009. According to statistics, in 2010, an 8% increase in the production of sunflower oil. It is true that 83% of the total production of the product was exported. It may be that all that will be grown up, already will be sold for a year forward, as it was in Ireland in the XIX century, when England bought up the entire potato crop in this country, causing a famine there, which resulted in a hungry winter killed more than 1 million people. Every year in Ukraine, an increasing number of the urban population. This figure has already reached 70% of the total population of the state.
Ukraine has always been an agrarian country. For our parents' usual occupation was working in home gardens. What we have today? System destruction of the agricultural sector at the global and private levels. Due to the rapid development of economic performance before 2008, the state of living also improved. In this new generation for the past 10 years due to improved financial condition, wean mass physical work. Wages paid for sitting in the office and talking on the phone. A lot of physical work was automated and did not make sense to grow potatoes, as it cost much.
