subfloor device in a wooden house

During the construction of a country house or replacing old floor with a new one is very important draft floor.

most common type - subfloor on joists.

to do it, do not need special skills, it is not difficult.

Such provisional flooring is designed exclusively for dry buildings, but not for baths or saunas, toilets.Boards can not tolerate moisture.

subfloor on joists

Laghi - is simply beams that form the basis forfloor straightening.Lags is not planed boards of pine needles.In a private house the board can be changed to strong logs, pre-prepared.

logs have bumps and ridges, so their upper part, on which a final bed floor in the future, to be a little bit to adjust an ax.

Aligned logs are placed in the grooves carved into the walls.Between the wall and the position of the log must remain a small gap of 3 mm to the floor did not create scratches.

Besides slots, logs can further rely on brick pillar.

to board was not exposed to damage from pests, its edge is covered with an antiseptic or treated with bitumen.When it comes to styling, you should keep in mind that the log has to be 60 cm thick.

This is a required minimum.If the subfloor beneath thick logs are taken, they can be placed on a meter apart.

main support for the preliminary floor in a private home will beam with a cross section of 50 to 50. It is screwed on the screws on both sides of logs.

beam it is necessary to fasten tightly and in all places, otherwise, it may fall.

, bars must be fixed along the length of the lag, considering the fact that the floor still need to be warmed to correctly lay the rough floor with his hands.

For example, the insulation thickness - 10 cm, rough boards - 25 mm in thickness.Then the gap between the upper edge of the timber and the bar must be maintained in 12.5 cm.

If a thicker layer of insulation, then this figure will be higher.

If rough floor in a wooden house made of logs, its styling may entail some problems.

On the sides of the logs sticking out knots, there are small recesses, because identical to saw boards is not possible.Only one way out - to cut each board in turn.

If you choose to use thick boards, you can be calm and boldly cut.Each board is placed on one bar that was bolted to the edges of the timber.

The boards are driven nails or screws are screwed.To carry out further work on the floor temporarily throw a strong board, so it is not broke under the heavy weight.

Many tips on making the sub-floor in the above video.

Assembly subfloor

Next starts installation of the remaining layers of the ground.On the draft floor in a wooden house after the installation roughing lag prefer to fix cranial bars.

They feature low section 4 by 4 centimeters.Bruschi put at the bottom side lag.

as cranial bar is possible to use the board.But it must be more than the width of the logs, it is desirable to four centimeters on all sides.

Such a board nailed to lag in two places: at the bottom and along it.

Next, the laying of boards over the cranial bars.Boards do not have to be fixed to the bars and joists.Installation of the boards has a caveat.Their trail freely, so they just kept a layer of insulation.

then you should use an antiseptic that prevents wood rot and insect damage.They should definitely be treated and cranial bars and joists, and all boards.

is recommended to repeat the disinfection after 2 hours.

important point - waterproofing.Sex is necessary to cover the waterproofing layer on the entire height of the floor of the future.Waterproofing performed using films which are bonded together by a stapler.

protection of surfaces from moisture, producing insulation.If the insulation material is good fit, it is possible to insulate the floor, even the two layers.

Just as waterproofing, steam is produced.The same subject of the film fastened to go for the rest of the floor height.In addition, the film pieces can be glued shut.

Further measures - ventilation, which is created using nailed along the counter-lag, laying wooden flooring, which play a role chipboard or OSB, and sound by using sheets of chipboard.

But preliminary floor installation can be done differently.The easiest way to get a strong floor on joists - perform stacking OSB.

This method is relevant if in a private home columnar-pile foundation, and the distance between the lags corresponds to the size of the OSB.

first passes styling rough rolling along lag nailed bars.Then, OSB plates from the inside should be covered with mastic asphalt (so waterproofing is carried out) and put them on the joists.

OSB is fixed to joists with nails or screws.Nails hammered in the plate at a distance of centimeters from the edges, so that later OSB is not covered with cracks.

How accurately perform the installation slabs, shown in the photo.

then carried on OSB installation isolating film a few millimeters thick.Then it is necessary to use foam or mineral wool to insulate the floor.

Performing insulation, make the installation of yet another layer of OSB.

Dry floor screed

How to create a rough floor of wood became clear.But good wooden floor in a private house, and lay in the bath board is not profitable, they will quickly deteriorate due to moisture.

same apartment, where there is a bathroom and toilet, and in an old brick building, which is already built a concrete floor.Therefore subfloor unit in a location to be different.

In this case, the floor may align with a concrete screed, a popular self-leveling floor screed or a dry method.

The last option is a low cost.

This rough screed in the apartment will require a damper tape, plastic film, expanded clay and plywood - a wonderful material for the preparation of the base in the skeletal structure.

From the Tools needed:

• screwdrivers;
• jigsaw;
• roulette;
• line;
• screws;
• marker.

on a platform of concrete spread out a vapor barrier of polyethylene film.It necessarily trail with an overlap on the wall at 10-15 cm But in the joints of the film pieces do overlap even more -. 20 cm.

edges close up with tape so they will not sprawling.

Next on the perimeter of the house paste damping tape.The tape must be attached to such a height, on what will be backfilled concrete block.With

water level set beacons to achieve a smooth surface.

After that poured concrete block, level it, focusing on the raised rail.Minimum layer of expanded clay - 2 cm

better not to pour out all at once, and often, it is at first only a single sheet of plywood..

When laid subfloor of plywood, there are some disadvantages.After walking the first plywood sheet will show that it is "drowning" in Leca.

It's not scary, placing the other layers, it will be possible to ensure that the dry screed acts: flat plate and do not move sideways.When it is laying plywood boards try not to move too much.

They weigh up to 17 kg, and drag may lead to deformation of expanded clay layer.
Joining plate advise screws.Standard interval between - 12 centimeters.

to soldering sheets was the most strong, their joints are smeared with glue PVA.It is better to put the waves and not a lot, because after the plates are fastened with screws.

How exactly to apply the adhesive, shown in the photo.
then all joints must be covered with plaster and trowel.After drying, it is necessary to level the base, that is to use polishing.

If you are dry screed in the apartment with a bathroom and bath, the plywood boards must be treated with a special mixture.So waterproofing is guaranteed home.

protective structure can serve as a mastic asphalt or cement.Do not forget about insulation.

How to make a dry screed plywood, look at the video.

Fill subfloor on the ground

device subfloor can be done cost-effective method.Since the preliminary floor can be poured on the ground.

But this type of sub-floor is only suitable for such facilities, under which the soil completely dry.

design nonfatal floor on the ground do not need to install the beams, it is important to make a pillow on the ground floor and make insulation.

need to tamp the ground before filling sub-floor on the ground, so that the soil does not give shrinkage and the floor was flat.When the soil hardened, it put a pillow of sand.

layer is moistened and compacted using a vibrator.As a result, it must be reduced by 25%.Top for hardening poured granite layer.

next stage of training the auxiliary floor on the ground - waterproofing.To completely limit the penetration of moisture in the house, it is a must.

For protection from water is more appropriate bitumen rolls or polymer membrane.Waterproofing does not allow the use of polyethylene fabric that trail in one piece without seams.

Matter put lapped and joined with tape.

Waterproofing must be carried out carefully, the material has not been damaged and torn.The material must go to the wall, about 20 cm, the excess is cut off after the final tie.

prior installation on the ground floor are beginning to fill with a thin layer of concrete.It is a platform for steam and waterproofing.The raw material for roughing concrete screed concrete is a Class B

As filler used rubble diameter up to 22 mm.

optimum thickness of the rough layer is between 40 and 50 mm.Must carefully pour concrete, so that the horizontal layer was not more than 4 mm.This is verified by the building level.

How to pour concrete and do not make a mistake in the calculations, will teach the following video.

Then go to the layer vapor barrier.The best screen protector - a polymer-bitumen membrane containing polyester or fiberglass.

This material will allow to spend less on heating homes.

Thermal insulation foam can be made.This option is ideal in the frame structure, such as a garage or warehouse.Also, nothing prevents warm home polystyrene foam or mineral wool.

In general, filling the floor on the ground is not a complicated process, and it can be done quickly and fairly easily.

This method is often used in frame house, whose construction is very popular.The lower floor is the base on the ground, then you can preview the wooden flooring.

A support base in the frame house covered with slabs.The finished base must comply with all the rules, it depends on how much heat will be in the frame construction.
