the Roof from tesa

The Basis for a board roof serves obreshetka from bruskov as section 60x60 mm or the poles in diameter of 80 mm squared in two edgings. Bruski of 600-800 mm are put on rafters with step. /

For a board roof take a board in the thickness of 20-25 mm from wood of coniferous breeds. Stack them in two layers: boards of the bottom layer put a core downwards and beat to obreshetke one nail; boards of the top layer steljut on bottom so that it has turned out polovinnyj close. The core of the top boards should be turned up. Them beat to obreshetke two nails in each crossing. Boards of the top layer should be ostrogany from different directions, and boards of the bottom layer from below not ostragivajutsja. For a drain of water along edges of each board do fillets. /

There are two ways of packing of boards at the device of a board roof: cross-section (across a slope) and longitudinal (along a slope). The longitudinal laying is more practical and is widely used. In a longitudinal direction of a board can be laid:

  • end-to-end in two layers, thus a joint between boards of the top layer it is necessary on the middle of a board of the bottom layer;

  • in one layer with formation nashchelnikov, thus the bottom layer becomes continuous, and the top boards block edges of the bottom layer on 40-50 mm;

  • boards of the bottom layer keep within with backlashes, and top - block their edges not less than on 50 mm. The top boards krepjat to obreshetke two nails in a place of each crossing. /
Ways of the device of a board roof

a Fig. 42. Ways of the device of a board roof :

1 - a board of the bottom layer; 2 - a board of the top layer; 3 - a fillet for a water drain; 4 - a nail; 5 - the loose leaf; 6 - konkovaja a board; 7 - a strip from a roofing steel in width of 100 mm; 8 - ruberoidnaja a tape; 9 - konkovyj a board flooring; 10 - brusok obreshetki

The Cross-section way of packing of boards is supposed for time constructions, thus it is not required obreshetki. /

The Top boards block bottom on 40-50 mm. Each crossing of boards with rafters is fixed by one nail (fig. 42).
