The bar is used for construction of owner-occupied dwellings not higher than three floors. Thanks to its rectangular shape it is possible to receive at once beautiful plain surface of walls which allows to do inside and external lining easily.
Base
At houses from bar rather big weight therefore they demand the rigid and reliable base. If soil muddy, friable and damp, for construction of the base is chosen by screw piles. When under the house it is going to make cellar or the basement, preference is given to continuous footing, it is suitable for all types of owner-occupied dwellings.
The small house can be built on the solid plate base, in this case it will serve as draft half of the first floor. On soft soils with the high level of freezing use pile rostverkovy the base.
Construction method
The breeds of tree which are the most suitable for independent construction — pine, larch and fir-tree. The first wreath of the house from bar is stacked on double layer of rolled isolation with which cover the base. Insulation layers are put in turn with the bitumen warmed to liquid state. Its width has to exceed base width on 30 cm. After that it is possible to begin works with bar. The quality of all building depends on proper assembly of the first wreath. Each part needs to be processed previously anti-septic tank, it will protect tree from rotting and damage by insects. More effectively to do impregnation of separate parts, than all house. The first lining board strictly fix to the base through waterproofing layer. It will be necessary to attach the outflow protecting the house from precipitation to it. The first wreath can be stacked in two ways — on lining board or on cross rails. Connection thorn groove on the top and bottom side of bar allows to join most densely elements among themselves. Each new number of bar is stacked on layer of jute mezhventsovy heater, and wreaths connect by means of swamping of dowel on depth of 30 cm to step 1 m.
Arrangement of roof
Without having special skills, it is the simplest to make duo-pitch roof. The bar of 150x150 mm is chosen for the mauelat which fix to wall wreath by means of anchor bolts, brackets or dowels. On mauelat rafters will lean. In order that to attach them and to provide them possibility of shift, "sledge" is the best of all to use steel fastening. It consists of two elements allowing to change rafter corner owing to shrinkage of the house. The rafter system represents the framework executed from strong bar. As a rule, for its creation use bar from 50 mm thick and 150-180 mm wide. The system is covered with vapor barrier layer, and from above establish counterfurring and furring which is nailed up across rafters. Counterfurring is done of rails 2 cm thick, they are filled on insulating material.
