Now there are many types of finish coatings for sex, which are innovative products of the construction industry. But over time, the device of the wooden floor by lags has not lost its popularity. We will discuss the conversation about this technology in our article.

Advantages of sex using lag

Wood floor is a traditional flooring for residential rooms. Thanks to absolute naturalness and attractive decorative form, the tree is the most favorable option when the floor is installed.

Wooden floors on lags also have the following advantages:

• excellent sound insulation and thermal insulation qualities;
• uniform load distribution for the base;
• the possibility of using space between lags for laying communication systems;
• carrying out floor alignment with lifting it to a given level;
• high strength (can withstand load up to 5 t / 1 m²);
• solid operating period.

Wood flooring does not require special knowledge in construction. Installation work is carried out in a rather short time. This uses the minimum amount of materials and tools. What significantly reduces the price of wooden floors on the lags. As a finishing material for the wooden floor, you can use paint or varnish.

Wood selection nuances

When laying a wooden floor, special attention should be paid to the purchased wood. She must be:

• dry (wet boards after some time are deformed);
• without mold, large bitch, chips, cracks and other defects.

When buying tipped and edged boards, it should be noted that they are not subject to additional grinding. Purchase of wood is carried out with a 15 percent reserve.

All wooden boards are coated with antiseptic agents and antipirens. Only so in the future you can avoid the negative impact of pests and fungal diseases, as well as reduce the flammability of the tree.

When creating a warm floor on wooden lags, the choice of wood is carried out depending on its type. The most suitable option for residential premises is pine, spruce, larch, fir and cedar. They have excellent wear resistance, strength and small cost.

For children's rooms and bedrooms it is better to use oak, aspen or alder. They cost a little more expensive, but possess better characteristics.

When purchasing wood, other factors are taken into account:

• climatic conditions of terrain;
• view of the room;
• features of operation;
• planned loads;
• financial opportunities.

Features of the installation Lag.

This process is carried out on the basis of the type of base. In most cases, it is necessary to deal with its three species:

• concrete overlap;
• wooden base;
• earthy floor.

The installation of the lag on the concrete basis is performed in the following order:

• the concrete base is aligned with a screed;
• the screed after drying is covered with waterproofing material;
• lags are mounted;
• if necessary, the insulation is stacked between them.

Metal corners with zinc coating are used to fasten the lag to the concrete overlap. One side of the corner with the help of a screw of a depth of 3-5 cm is connected to lags, the second is connected to a concrete base with a dowel 6-7 cm long.

In most cases, the installation of lag for the floor of a wooden house is carried out in the side of the beams. The main reason is uneven wooden floors. For this purpose, galvanized corners and self-tapping screws are used, the length of which is 2.5 times higher than the thickness of the bar.

In the presence of the base from the Earth, the lag flooring can be carried out in two ways:

• by sealing the soil and subsequent fill of the concrete solution;
• using the use of brick supports.

The first option consists of such steps:

• removal of the soil layer;
• failure of gravel layer to 5 cm;
• pouring a concrete solution (a thickness of 7 cm also).

Further installation of lag occurs similarly to their laying on concrete overlap.

For the device of brick supports, formworks are created in which the concrete solution is poured. One lag may fit into a few supports. Based on:

• placed waterproofing material;
• mounted supports of bricks;
• lags are attached to them.

We will focus in more detail on the installation of lags and support columns made of wood. First, it is necessary to determine the cross section of the lag. Typically, the ratio of their height and width is 2 to 1.5.

The specific size of the material is determined based on the size of the floor covering. If it has a greater thickness and has increased strength, it is better to use lags with a minimum cross section.

Be sure to take into account the presence of a ventilated space of up to 3 cm, which is located between the insulation and the level of clean floor.

An important factor for high-quality styling of the finish coating is the distance between the lags of the wooden floor. This indicator depends on the actual load on the floor and on the thickness of the floor covering.

There is the following dependence of the thickness of the lag and the steps between them:

• with a thickness of up to 2.5 cm, the distance between lags is 0.3-0.4 m;
• 2.5-4 cm - 0.6-0.7 m;
• more than 5 cm - 0.9-1 m.

The minimum distance between lags leads to the creation of a stronger and reliable floor.

Lag flooring can be carried out in two ways:

• in the transverse direction to the passage (it will be convenient to put the boards along the movement);
• along the long sides of the room (start working with extreme lags mounted with a gap 3 cm from the wall).

In the doorway, which connects the neighboring rooms, placed extended lag. It should perform on both sides by 5-6 cm from the partition. Flooring, stacked in two rooms, relies on one lag.

When installing lag on overlaps made from reinforced concrete slabs, waterproofing and sound-absorbing gaskets are used. A polyethylene film or rubberoid is used as a waterproofing, soft fiber plates or polyurethane are used as a soundproofing material.

The humidity of the gaskets should not exceed 12%. Laying pads are made under lags in the longitudinal direction. They are placed in a solid strip without breaks. Gaskets protrude 10-12 mm on each side of the lag.

As sound insulation materials can be:

• mineral wool;
• sand.

Mineral wool fill the space that arose between the lags. The lags themselves are covered with a substrate made of rolled cork.

For submetock, you can use sand. But this material must have the following properties:

• lack of organic impurities;
• material moisture at up to 4%;
• the content of clay particles within 3% and less.

When installing the lag immediately, their leveling is performed. They are placed in a single plane. The correct horizontal position of the lag is checked by a long rail and construction level. The rail must come into contact with all lags without the presence of a gap.

Sand can be used as an aligning material. It can be satisfied both under gaskets and under lags. In the level of alignment, the lag is not recommended to use:

• wooden wedges, pounded under lags;
• lining made of wood.

If the lag is aligned, which are stacked on the support columns, then use the pads from the chipboard.

Many are wondering: how to additionally fix the lags to the ground and with each other? In the first case, cement-sandy solution is used. The insulation of the lag from the laid solution is made using mastic.

The lag connection between itself leads to an increase in the stability and stiffness of the crate. Stage bonding occurs using edged lags and corners of galvanized.

It is advisable to take advantage of Parchment sheets. They are laid out the peaks between the finish flooring and lags. The main purpose of Parchment is to prevent the negative effect of condensate and evaporation on the floor covering. The laying of the sheets of pergamine is carried out as the boards laying. This uses a building stapler.

Wood floor device for lags

Laying the wooden floor on the lags begins with the correct installation of the first tipped board. It is a guide for the rest of the boards and must have a sufficient length. The face part of the boards does not adjoin the wall close to the wall. The clearance contributes to the normal expansion of the boards during their operation.

The first board is placed in spike to the wall. The clearance is 1-1.5 cm (it will later close the plinth). Outdoor coating is located in the perpendicular position to the side of the room. The first board must be positioned in such a way that the screwdrive screws are under the plinth.

Mounting works provide a dense press of boards to lags. Before screwing the screws in the grooves of the boards, it is necessary to make holes with a thin drill. Thanks to this procedure:

• the groove becomes more resistant to possible cleavage;
• screw to the lagham as close as possible.

The board connection is made using metal brackets that are driven into wedges and lags. Installation of subsequent boards is carried out in one of two ways:

• fastening each board to each lag;
• fastening every fourth board to each lag.

The first option involves the use of only normal dried boards. This most time-consuming method. But he leads to the maximum dense fit of the boards to lags.

With the help of a second, faster method, there is a combination of grooves with ridges for three rows of flooring. The fourth board holds all four rows. This flooring technology makes it possible to replace in the future of tipped boards.

The procedure for connecting board consists of the following steps:

• in the groove of the foreskin, located on the fourth lag, the trim with the ridge is inserted;
• it serves as a laying between wedges and a board;
• in the lags at a distance of 75-80 mm from the gasket, brackets are clogged;
• the wedges are inserted between the bracket and the board;
• wedges are clogged with hammers until the board is completely connected throughout the floor area.

To ensure the maximum uniform board of boards, the wedges are climbing along the entire surface of the floor where the brackets are installed. After the end of this work, the boards are securely fixed to lags using self-tapping screws. Wedges are knocked out, the brackets are removed, the laying boards are cleaned. Similarly, the boards are connected in the following sections.

The last three rows of boards are stacked in the room along the entire length. Usually, the brackets are already difficult to insert. The board connection occurs as follows:

• a plywood leaf is leaning against the wall;
• using scrap, the latest boards are mounted.

When installing the last plan, most likely, you will have to use the electric jigsaw. Since the board usually has non-standard dimensions. In width, it should be such that without any problems to enter the closed space with the presence of a gap to 15 mm. Fastening the last board occurs similarly to fixing the first. Self-tapping screws should be hidden under plinth.

As for the rates for wooden floors on the lags, their laying will cost the owner of residential real estate within 8-12 dollars. / 1 \u200b\u200bm². It all depends on the state of the surface on which the installation of the lag is carried out.
