Erect hardwood floors between floors , construction technology

Hardwood floors between floors is typically used in low-rise private construction of houses made of wood, brick or foam blocks.Hardwood floors have a number of advantages: they are not heavier construction, eliminate the need for involvement of heavy equipment, possess sufficient strength and reasonable price.

choice of material for wooden floors

Hardwood floors satisfied with the span width of not more than 8 meters.The main load-bearing structures using beams from the beam with a cross section of 50h150 to 140h240 mm or debarked logs corresponding diameter.Step beams is determined by calculation, and is usually from 0.6 to 1 meter.To produce beams take only coniferous woods - their strength under bending operation is considerably higher than that of hardwood.Logs and timber for beams must be thoroughly dried in the air under cover.When tapped an ax beams should issue clear sound sonorous.The length of the floor beams must be such as to firmly build nests in masonry or log.

Also beams to perform intermediate floors used:

• Cranial bars with a size of 50x50 mm - they are fixed to the bottom of the beams from both sides and hem them the ceiling of the ground floor;The board
• rough upper storey floor.For this purpose, you can take any board including planed;
• top floor boards floor - planing decking;
• Insulation.As the insulation in wooden ceilings better to use mineral slabs or rolled material as the fiber thermal insulation, unlike the foam does not support combustion and has good noise proof properties;
• Gidroparoizolyatsionnuyu film designed to protect the insulation from moisture moisture vapor;
• Antiseptic for wood and bitumen mastic, roofing trim;
• Decorative flooring and ceiling.

technology implementation hardwood floors between floors

Beams intermediate floors lay in the wall usually during the construction of the house, and all other work on ceilings construction carried out after construction before finishingworks.Before performing the overlap is necessary to make the load calculation on the floors, on the basis of the data selected sizes of beams and a step of laying.

1. beams overlap in a brick or block wall give birth during the laying, for that special slot is performed in the wall.The depth of the nest should be no less than half the thickness of the wall, you can make it through with the subsequent sealing of vapor-permeable insulation.

2. In wooden buildings beams cut in the upper crown of the framework.Beams need to be pre-treated with antiseptic and prosushit.Ukladyvayut rectangular beams so that the broad side is vertical - at such laying their rigidity increased.The ends of the beams are cut at an angle of 60 °, and treated with mastic asphalt roofing material wrapped in two or three layers.First placed on the extreme position of the beam.They are aligned with long boards set on edge, and the level, if necessary beams equalized by the boards pads of different thicknesses pretreated bituminous mastic and placed in the slot.Intermediate beams are aligned on the extreme beams laid on the board.

3. proceed to the construction of floors and walls After the temporary or permanent roofs.By the bottom of the beams on both sides sutured cranial bars.Their purpose - support for rough floor and the upper floor to the lower ceiling filing.For cranial bars needed pine timber 50 mm, treated with antiseptic.For joists it is attached with screws on wood.On cranial bars stacked boards sub-floor.They can be used unplaned board thickness of 15 mm - load on the rough floor is small, so splurge on a thick board is not required.Boards are placed perpendicular to the sub-floor joists, drawing them into the cranial bars, and secure the screws.Rough sex is treated as an antiseptic.
   

   process of installing subfloor

4. top of the subfloor and joists placed gidroparoizolyatsionnuyu film, for example, Izospan.Film Strips are placed overlapping, prokleivaya tape joints.Over isolating film laid the mineral insulation in the form of slabs or rolls.The thickness of the insulation must be such as to not protrude above the surface of the beams.It can be used as insulation and other materials: expanded polystyrene, expanded clay, ecowool.It is necessary to pay attention to the fire insulation material.
   

   process of warming the floor

5. top of the joists put a floor joists of the upper floor.The direction of laying the lag - across beams, step - from 60 cm to 1 meter.Laghi operate from the bar or board with a minimum thickness of 40 mm and attach them to the joists with metal parts, fixed on screws.Between the beams can be put another layer of mineral insulation, ceiling joints of the lower insulation layer.Mineral insulation will also sound-proofed floor and ceiling.On top of the second layer of insulation waterproof film placed in the event of liquid spills.

6. Sex on the top floor joists sewn finishing floorboard, gypsum board or plywood, which can be installed at any surface finish: tile, laminate, linoleum or cork.Floorboards or plywood fastened to the screws.You can arrange a topcoat warm water floor, while as a vapor barrier is best to use foil wrap.

Hardwood floors between floors, in contrast to the concrete slab, do not create unnecessary burdens on the foundation, therefore, can significantly reduce costs for the construction of a strong foundation.Proper overlap sufficiently strong and durable, it has good heat and sound insulating properties, in addition, allow overlaps natural materials to "breathe".
