Laying wooden log : Master Class

plank flooring made of different materials.Regardless of the materials used, they should be smooth, with no gaps between the boards and does not sag.Properly installed wooden joists are the basis for good nastlannogo floor.Perform work on the installation and device lag floors should be in dry weather at positive temperatures.

for wooden floors on joists must meet strict requirements.They are made once in a long time.The underground must be dry and the basement of the building provided the vents.Beams and joists are treated with antiseptic and placed in dry wood with a moisture content not exceeding 12%.

calculation and selection of the beams of the wooden floor wood lag

Laghi - in fact, the wooden cross beams which are laying a floor cloth.Properly designed and produced by stacking wooden lag ensures proper load distribution, heat - and sound insulation.In the space of the underground communication systems fit plumbing and electricity.The main purpose of the lag is smooth and dry floors.

section calculation and lag step for wooden floor

beams are selected from solid softwood or hardwood.Pine, beech, fir, alder and elm are ideal for arranging lag.Lag beams have a rectangular cross section with a height to width ratio of 1: 1.5 -2..

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;
• thickness of the boards - 45 mm lag step - 80 cm;
• thickness of the boards - 50 mm lag step -. 100 cm

selection of quality solid wood for flooring and lag

for laying wooden floors on joists selected board of not less than 35 mm hardwood.Alder, aspen, beech or oak is quite suitable and popular wood for flooring.The difference in price depends on the hardness and durability of the timber.

1. For outdoor deck under the varnish is selected board first grade without knots and defects.The wood floor before painting, you can choose variety below.Note the solid wood humidity.It should be within 12%.Too wet floor after installation when dry can warp or twist.Excessively board has a tendency to crack.
2. To prevent lag and floor boards from rotting, mold and bugs wood treated with antiseptic solutions.Low flammability is achieved by impregnating wood antiprenom.Lower crowns homes and places of fastening lag undergo similar treatment.

Preparation of underground space and crowns the house-to-install lag

Wooden joists are arranged on the earthy, concrete base or on the beams.Before installing the lag works on waterproofing and sound insulation floor foundation.

1. Zemlyanov space between the lower rims of the house carefully leveled and compacted.It pours a pillow of sand and gravel.Produced by marking the support posts and laid waterproofing film.
2. to the concrete base on a pillow of sand and concrete on top of the waterproof film is placed welded from 8 mm reinforcement lattice.Cells reinforcing lattice made of about 15x15 cm The base is filled with a layer of concrete thickness of 8 - 10 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.

Installation of wooden lags for floor covering

in the lower crown of the house, if the construction did not include slots for mounting must be their lag proshtrobit.Inset is turboshlifovalnoy machine with a disc on the concrete.Paz matched either a hammer and chisel.

1. horizontal plane exhibited lag and adjusted using a long rail and construction level or rule.Testing is carried out on the axes and along the diagonals.To correct fitting and use hard wood or plywood backing.
2. The end of the lag set in the crown of the lower house are laid with gravel nest and smeared cement mortar.For wooden joists intermediate the posts are fixed with screws.To prevent cracking previously drilled seat mounting.
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.

Insulation of underground space and the installation of a wooden floor

for underfloor heating and a comfortable indoor climate warming is carried out underground space and improvement of ventilation ducts if they were laid during the construction of the house.

1. The space between logs stacked basalt wool or polystyrene.In areas with a mild climate sometimes lags between cell is filled with expanded clay aggregate.In the lower house cut crown ventilation holes with a diameter of 10 cm, into which the metal sleeve and the protective lining with fine metal mesh.
2. Installation of the wooden floor on joists starts from the far end of the room.Stepping back 10 mm from the wall, exhibited the first floor board tongue to the wall.The gap will disappear afterwards skirting, and it is necessary to compensate in case of expansion of timber.The opening angle under nasverlennye are driven nails or screws are screwed so that the cap is recessed at 2 - 3 mm.
3. following rows tightly pressed into the slot and egged wooden mallet.It is important to bear in mind that when laying the wood floor planks annual rings on a longitudinal section of the boards had the opposite direction.Short boards floor boards mounted with an offset.The last board is attached with nails or screws at an angle of 65 ° - 75 ° in the direction away from the wall so that the cap concealed plinth.
