The design of building windows and doors

Svyatoslav Otychko Where the log wall becomes a window or doorway, need particular support. Angular vrubka here will not work because the end of the timber is filled. Used to strengthen the spine - a vertical strap that goes wills end walls and obstacles to its bow. We show you how to do the right design. Tools and Materials 1. Board, whose thickness must be equal to the width of the timber 2. Wooden beam sizes 38h70 mm 3. Drill 38 mm Attention! In the manufacture of thorns design must consider the further drawdown of log walls. Normal descent - about 4 cm per meter vertical wall. And because the spike-strap in practice is not changing, then the studs design should take into consideration beforehand for every 1 m box 4-cm subsidence, and in 2-meter doorway - 8-cm subsidence. Cruising on precipitation must be considered in the first log-bridge. Process: 1. For greater stability is best to use double spike. This will require the board, whose thickness should be equal to the width of the timber, and the size match height of a window box. Also, studs lath thickness of about 38 mm in size 38h70 mm. Since the strap studs during construction should immediately go a little beyond the upper beam, the size of the spike should be taken at 10 cm greater height window opening. 2. At the bottom rung of window cut a groove corresponding to the thickness of the sill. In the middle of each of the vertical sides of the groove is measured location groove whose width is equal to the width of the strip. The grooves are also marked on the ridge beams, their depth should be the size of the spike - about 70 mm. 3. At the end of the groove with one and other 38-mm drill bit drills a vertical hole to a depth of the lower window bar. Then the chainsaw saw through the grooves along the lines of markers. We perform the same and on the other side of the window opening. 4. Set the vertical studs-strap in the groove, nailing their nails. 5. Cut these connectors at the ends of logs, as most of the wall. Between the studs fasten temporary support legs that will keep the opening in the correct format during installation of the following logs. 6. Working in this way until the top log window. Then it all goes a bit differently. First of all we must remember that the design of a window box in the longitudinal direction does not shrinks, and the size of the height necessary to consider draft of the wall. To this end, the upper log-jumper doing the compensating subsidence groove to the top of the spike-strips of not less than 4 cm
