  1. step when installing the lag equal to 70 - 75 cm, depending on the span width of the selected section are:
  • span of 2 m - cross section 110h60 mm lag;
  • span of 3 m - cross section 150h80 mm lag;
  • span of 4 m - lag-section 180h100 mm;
  • span of 5 meters - cross-section of a log 200h145 mm;
  • span of 6 m - cross section 220h180 mm lag.

In the selection of the mechanical section of a log is taken into account the distance between the bars of the waist and the thickness of insulation layer.

2. Step lag depends on the thickness of the floor boards:

  • thickness of the boards - 35 mm lag step - 60 cm;
  • thickness of the boards - 40 mm lag step - 70 cm;

And is screed.After a day of "iron" to stiffen the concrete.The concrete surface is moistened, sprinkled with a thin layer of cement and smoothed a wide spatula.
  3. concrete screed to dry for at least 2 to 3 days, and then treated with a water repellent primer.In selected areas of bricks or wooden bars set intermediate columns under logs and settling down a second layer of waterproofing.On bitumen roofing mastic glued or rubemast.
  4. Installation on wooden log beams made with screws.Beams are processed antiseptic impregnated and trimming plane.Beams are not always installed perfectly horizontally.During mounting lag used wooden lining, and horizontal mounting check the length of the building level.For screws in the joists thin drill holes drilled.

  3. Brick intermediate columns are laid out in such a way that the last brick is perpendicular to lag.On the bricks laid waterproofing of roofing material and is attached with mastic asphalt.
  4. first installed two lighthouses lags at the opposite wall.On them are aligned and assembled the rest of the intermediate joists.Speakers plane down a plane surface, and in places troughs installed lining.Mounted on joists and metal corners are fixed with screws.
