One of the simplest for building with your own hands is a single -sided roof. This type of roof is characteristic of non -residential structures.
Design features.
• A single -to -shoe roof is carried out with a slope of 10 to 60 degrees, depending on the climate and the level of precipitation. The greater the slope, the more materials you need. • Naval beams are used in narrow buildings, with both ends, based on capital walls. • The most common material for layered rafters is wood, metal and other materials are not rarely used. • Forestial, allonical rafters are used in spans up to four meters. At a distance of five to six meters, the leg is necessarily reinforced with struts. • In a single -horned roof with a span of six to eight meters, rod farms with two struts and a grandmother are required. • In spans from eight to twelve meters, an intermediate beam will be required.
Calculations.
• It is necessary to take into account the climatic zone, the level of rainfall, the size of the passage. Based on this, select the material and determine the slope of the roof. • Particular attention is required to pay the quality of materials and not lower the slope in areas with high snow load. From a latitudinal climate latch to the northern regions, the minimum angle of inclination increases from 20 to 45 degrees. • Pay attention to the fact that different roof material requires an increase in slope. So for a metal tile will require a slope of at least 30 degrees, for a slate of 35 degrees, for flat asbestos -cement sheets from 40 degrees. • rafter leg – the main element of the layered rafters. Supported beam is an emphasis for its ends. Mauerlat (supporting beam) is laid on the internal cut of the support walls. For the legs, logs, beams, glosses are used. Logs and beams are laid at a distance of one and a half to two meters, for boards having less strength, the distance is less: from a meter to a half.
Schemes of single -sided roofs
It is important to know.
• Before laying, it is necessary to cover the wood with an antiseptic. After laying for waterproofing around the perimeter, they are closed with roofing material (optimally in a double layer). • For crate, use poles, boards, bees. A board with a step up to a meter is sewn across the rafter legs and a crate is made along it. The material is used dry, without knots.
The completed flooring should not bend under the weight of a person, there should be no hill, unevenness, cracks.
