Mounting the rough floor on the logs
Often in the wooden house as a material for the rough floor choose logs from the wooden beam. When installing such a foundation, you need to ensure that the logs do not touch the walls. It is necessary to observe a distance of 3 cm between the end of the lag and the wall. This gap is necessary to fill it with soundproofing.
Among the advantages of this version of the installation of the rough floor - low costs and speed of the laying process. However, it has an obvious drawback, caused by the rigidity of the fastening, - a low level of sound insulation.
Preparation of the roughing floor
Various logs can be used as logs. You can use even the third grade of wood, although such material needs further work. It is necessary with the help of an ax to level the surface of wooden logs in order to subsequently lay the ideal horizontal under. After that, they are covered with an antiseptic solution. There are two ways of installing wooden logs: on the base and on the overlap.
Installation of the roughing floor on the base
When using this method of installation, it is necessary to cut the loose soil layer, to level it and then to fall asleep with rubble. After the material is compacted, the marking of the area to be laid is planned. You can not put logs on rubble, for this you need to prepare supports, for example, wound grate roofing.
Support posts are installed only on the foundation. For this, it is necessary to dig holes along the line of the future lag with the same distance. Then gravel and sand are poured onto the bottom, ramming each layer. On the bottom you need to lay out a part of the grid from the reinforcement. The pit is then poured with cement mortar, which includes water, sand and cement. After installing the pillar-base under the lag and lay a waterproofing layer.
The next stage is the installation of a log. They are fixed to the pole by means of corners, dips and self-tapping screws.
Installing the roughing floor for overlapping
This method is good for mounting long logs. To fix the logs in the lower strapping of the wall, grooves are made with a depth equal to the width of the beams. Rubber pads are put on the ends of the logs to extinguish the noise, after which they are evenly laid in the grooves. Since one groove can not hold the beam, it is necessary to use a support for this purpose. For this version of the installation of a log for the black floor fit quite brick poles. They are installed on the same principle as the wooden base. Just need to build a brick pillar.
To determine the distance between two logs, you need to know which boards will be used for the top deck. The step of laying the lag decreases with decreasing thickness of the board. Do not ever forget about the laying of waterproofing material.
Steps for installing the rough floor
After the installation is complete, the laying of the different layers of the rough floor usually takes place, containing the following steps:
- We fix cranial bars having a small section at the bottom of the log and on the side. If you can not get these bars, instead of them you can take boards, the width of which is more than a log 4 cm. The boards are nailed in the likeness of the beams.
- The boards are laid on the cranial brusks. Their goal is to keep the insulation, so they do not require fixing.
- On top of the waterproofing material is laid in such a way that it covers the walls of the floor, as well as boards and logs. Suitable for this film waterproofing.
- Between the lags you need to put a heater. It is possible to lay two layers of foam foam - a material with a high heat reflectivity.
- The vapor barrier layer is laid, covering the walls of the floor. To fix it, use a stapler.
- An air gap is created, for which the counter-racks are nailed along the lag. This is done to provide a vapor barrier.
- Lay the wooden plank. As a material for finishing laying rough floor can be used sheets of chipboard, boards. As well as logs, boards should not be put back to the wall.
- To achieve sound insulation, DSP slabs are mounted.
Installation of a rough floor of concrete
A concrete floor of a rough floor is most often found in apartments, but many prefer a rough floor of concrete in wooden houses. The installation of the roughing base in the first stage consists in providing waterproofing and thermal insulation, as well as when installing the rough floor on the beams.
Before proceeding to pour the floor, care must be taken to prepare the guides that are fixed to the level to achieve a level surface of the concrete roughing floor. For pouring it is possible to use concrete-ceramicite, or it is possible by tradition - ordinary concrete. The first material is most advantageous in view of its noise-insulating qualities. After pouring the floor, we begin to level it and wait until it dries. And after that we enjoy the result.
