Single roofs are equipped on various buildings. It is not necessary to be a barn, a garage, a bath or a utility room. Such roofs are used in the complex roofing structures of cottages. Single rafter system is somewhat simpler according to the design than double and, accordingly, requires less costs and materials. The equipped lines of a single-sided roof lines with soft rolled materials or a sheet of rigid roof.

Single Single Roof System Device
The sloping system sloping system is selected depending on the roofing material used. The minimum inclination angle of 5-10 ° is allowed when using rolling materials like rubberoid or rubimist. To improve the roof from the wave slate, the rafter system of a single-table roof makes at least 20 °, and for the tile, the allowable slope is 25-5 °.
The scheme of the sling of a single-table soling system depending on the roofing material
When calculating the power of the skeleton of the rafter system, it is taken into account:
- the estimated weight of the roofing material, waterproofing and insulation;
- the weight of the solo system itself;
- wind and snow loads averaged for the region;
- a margin of strength up to 50% in case of natural cataclysms.
Constructive elements of a single sump system
For mounting a rafter system of a single-table roof, lumber of coniferous or hardwood resistant to parasites and rotting will be required. The permissible moisture content of wood for the skeleton of the rafter system is not more than 15-17%. The overall dimensions of the timber are determined depending on the calculated load on the roof, the total area of \u200b\u200bthe roof and the angle of inclination of the skate.
- For Mauerlat, Lenzny, tightening and grandmothers are used by the cross section of at least 150x150 mm. For rafting legs - board 50x150 or more. The timing segment from 50x50 is used to arrange spacers and inferior legs. An unedged board with a thickness of 20 mm is suitable for the crate, and for a solid feeding of plywood or OSB 10-12 mm.
- Mauerlat is called longitudinal beams, fixed on the upper wedge of the building. From the lower Mauerlat to the Upper Mauerlat, rafters are attached, and the vertical grandmother is a tightening.
- The upper Maurylalat or the longitudinal ski beam is installed at the upper point of the single sump system. The beam can be attached on the highest wall of the structure of the structure or adjacent to another wall, depending on the architectural project.
- The raftered is an inclined board connecting the upper and lower Maurylalat. The thickness of the board depends on the weight of the roofing material. A shaper is stuck on the rafter skeleton.
- Grandma is a vertical stand, supporting the upper Maurylalat or the ski run. The lower end of the grandmother rests on the tightening.
- The tightening is a horizontal beam connecting a grandmother with Mauerlat. As a result, a triangular profile of a rafter frame is obtained from the rafter legs, grandmother and tightening.
- Lena is a longitudinal beam, located in the middle of the attic space parallel to Mauerlat. Its ends are connected to a protracted beam.
- With a steep of the sling system and the length of the rafter whiteboard, more than 6 meters are installed additional vertical struts. They are mounted between rafters and Legene. From them at an angle are installed.
Doom - Unedged Board Passed across the rafter feet. The shading step is calculated depending on the dimensions of the roofing sheet. For soft roofing materials in rolls, the peel is made solid from the sheets of waterproof plywood, OSB, etc.
Tools and Materials for Mounting Single System System
From the tools for the construction of a rafter frame will be required:
- woodworking: tree hacksaw, carpentry, planer, chisel and chisel;
- measuring tools: Roulette, plumb, construction level, carbon black;
- drill, hammer, screwdriver.
Mounting and consumables:
- lumber: beams, timber, board;
- fasteners: nails, selflessness, staples, studs;
- insulating materials: rubberoid, bituminous mastic, antiseptic for wood.
Installation of a single-sided rafting system with your own hands
The stall and sawn timber drawings are treated with antiseptic and refractory impregnation for wood. The ends and planes of the beams that are fastened to the brick wall are processed by bitumen mastic. The samples and the upper crown of the wall in the places of contact with the wooden frame of the rafter system is locked with a rubberoid.
- Maurylalat is installed on the lower longitudinal wall of the building. For its fasteners in advance during the construction of the house of the house in the last row of bricks, metal studs are fitted. The diameter of the studs from 10 - 12 mm and more. Mauerlat's beam with holes drilled in size is installed and tightened with widespread nuts. In the process of installing the rafter system, nuts are periodically tightened. Wood has a property to slowly shrink, and the backlash formed is selected to a reliable consolidation of Mauerlat. Similarly, the upper Mauerlat or a run-in skating beam is attached. If Mauerlat is stacked throughout the perimeter of the house of the house, then the angular connections of the beams are made by cutting in the shell and additional fixation with nails and brackets.
- The rafters are attached by anchors, screws or nails to the beams of Mauerlat. The step of the rafter feet is calculated by the width of the roofing sheet. Two parallel legs of the rafter are located along the central line of overhelder roofing sheets, i.e. Step rafted by 15-20 cm already roofing sheets. At the bottom of the roof of the roof of the dipper performs 20-25 cm from the wall cutting.
- For the installation of spacers and subcording supports, in the ends of the bar and places of installation, a sample is made in Polmbus and nailed with nails. A metal corner, bolts or roofing brackets are used as an additional fasteners.
- Depending on the type and weight of the roofing material, a solid or sparse dory is made. A rarefied lamp is stuffed with nails in a step of 10 cm to half a meter. For it, you can use the unedged board, cleansed from the bark. It is important that the board will be the same thickness and evenly distributed on the plane of the rafter system. For solid crates, water resistant chipboard, OSB or Phanery plates are used. Bashed better galvanized self-drawing.
