Assembly of framework of roof for your country house, giving or small extension has to begin with predesigns of the sizes of all elements of future design. To execute such calculations it is correct, you have to know tilt angle of your future roof and its overall dimensions.
It is required to you
- ─ boards for mounting of supporting structure;
- ─ boards for production of rafters;
- ─ ridge board;
- ─ boards for roof framework covering;
- ─ corner;
- ─ construction level;
- ─ cord hank;
- ─ hammer;
- ─ wood saw;
- ─ nails.
Instruction
1. You fix on perimeter of roof of your construction basic boards which will form basis for all design of framework. For exact horizontal arrangement of such boards at their mounting use construction level. Basic boards fasten directly to overlapping of roof by means of nails.
2. Your following task is the arrangement at the required height of so-called ridge board. To resolve this issue qualitatively, you will need several auxiliary elements: two vertically exposed boards located precisely on the center of your future roof (to them you just will also beat ridge board at the necessary height).
3. Having calculated step of arrangement slung, begin their mounting, since pediment designs. Boards for rafters fasten in two places: to basic board on the basis of roof and to ridge board under the required inclination. It is important to observe precisely the chosen step of rafters and to mount them without distortions in vertical plane.
4. Since upper part of the received roof design, fix on board rafters for covering. At arrangement of these boards which can have smaller than rafters, cross-section, it is also necessary to adhere to the chosen step precisely.
5. Dismantle auxiliary designs and saw off the ends of rafter boards at identical distance from the roof basis (such distance has to be previously calculated taking into account the size of space of edge of ready roof from walls of your construction).
