When you want to use logs for the floor, the size of the timber is an important parameter to consider. Logs are parts of a lattice structure or solid flooring that are installed on top of the rafter legs. They are designed to strengthen and level the flooring. As a result, the lattice structure must be reliable and of high quality. In this case, logs are an irreplaceable thing, without them it is almost impossible to level and strengthen the floors.
The flooring without additional reinforcement with lags will sag under the significant weight of the furniture, and creaking and vibration are not excluded.
Importance of using lag
Logs perform the function of leveling the flooring, which is required for subsequent stages of construction and decoration. The lathing from the log performs the function of ventilation of the underground space, which reduces the risk of fungus and rotting of the boards. This function is most relevant in houses whose floor is placed on the ground, since even the highest foundation will not save you from getting damp into the house.
Thanks to the use of a log between the top layer of the flooring and the bottom one, a so-called buffer cushion is formed, which maintains and even improves the sound insulation of the house. In addition to sound insulation, a buffer pillow, namely the free space between two layers of the floor, is used to insulate the flooring or to lay pipelines and other things.
The reinforcing structure made of logs will make the floor durable even if its base has significant irregularities. It all depends on correctly defined and established support points.
Materials for the manufacture of crates
Flooring is a fundamental element, so any durable material that will withstand weight loads will work under the base. These characteristics are suitable for parts made of durable plastic, metal, concrete, wood. The best and budget option is wood, namely ordinary wooden bars.
For the manufacture of timber, coniferous trees are mainly used, such as spruce, pine, fir, however, larch is recognized as the most durable material, since it is resistant to decay. When choosing a material, or rather, wood, you should not pay attention to its various defects, given the tarred areas, a tree of not the first grade is suitable for a log structure.
The reliability of the floor and its coverage depends on correctly selected logs, so before buying, you must clearly calculate the length and width. Usually there are no problems with this, the main thing is to leave 3 cm between the wall and the structure. The space is left for the reason that when the temperature drops, the wood tends to breathe, and so that the already finished floor does not begin to bend, it is necessary to leave some space for it.
It is better to select bars according to the size of the room, however, most often they use splicing two parts with the help of fasteners. The splicing process itself is simple. It is important not to miss the nuance of creating a support for such a spliced place. As a support, small columns in size are often used, supporting the structure with them.
When creating a lag structure, it is necessary to lay the bars on the edge. This method of laying will provide maximum rigidity of the structure with minimal material consumption. Basically, the thicker the lag, the stronger the floor surface will be. In the event that you decide to use metal or concrete as bars, it is worth remembering that they can be thinner, as they are more resistant to deflection, unlike wood.
Laying process
Logs made of wood can be attached to any basic coating, but it is important to observe all the subtleties of installation. You will need:
- wooden bars;
- saw or jigsaw;
- level;
- screwdriver;
- elements for fasteners.
It is imperative to fix the lags, because at the slightest movement the whole structure will be doomed to failure. It is necessary to mount the structure to concrete or soil using additional fixing methods.
On the ground, laying occurs as follows:
- trenches up to 10 cm deep are initially pulled out;
- covered with sand;
- covered with polyethylene;
- brick pillars are erected;
- sheets of roofing material are laid on top;
- lag construction is installed.
On a wooden base, fasteners do not take much time and effort, it is enough just to attach the bars to the base using self-tapping screws. The resulting holes must be drilled to prevent splits and cracks in the timber.
Conclusion
Logs made of wood are not only budgetary, but also the best option for strengthening and leveling floors. By following all the rules for choosing bars and installation, you will achieve the desired result in the form of reliable and durable floors.
