FIELD: construction.SUBSTANCE: method to manufacture a wooden composite building bar includes treatment of boards and their joining with the help of fastening elements. Fastening elements are represented by a tape. Between boards, inserts are installed, for instance, of trapezoidal section, and holes are made in external boards, perpendicular to the axis of the bar and direction of the heat flow via a building structure. The tape is pulled into holes, tightened, and ends are fixed, for instance, by means of welding.EFFECT: reduced labour intensiveness of a bar, its lower weight and improved heat insulation properties.4 dwg |
