The alignment of the concrete base for laying the topcoat can be performed using logs, which are boards or bars. It is possible to attach logs to the concrete, either using rigid anchors or in a controlled manner. If you mount the frame on a concrete floor, then under it forms an underground, the space of which can be used for laying communication networks. Installation of the frame of the bars contributes to the creation of proper ventilation and improvement of noise insulation in the equipped room.
Layout of the support lags.
Often the traditional method of creating a framework from uneven bars is used. If you attach the logs to the concrete with anchors, you can not only fix, but also press them to the base. This ensures uniform distribution of the load on the floor. The length of the anchoring should be 5 cm greater than the thickness of the beam. It is necessary to lay a layer of waterproofing made of a hard material on the floor, as a soft insulator will cause the structure to float. The insulation is mounted after mounting the frame.
To perform a lag fixation, the following tools are used for work:
Lag mounting scheme for a concrete floor.
The work is performed in this order:
Between the bars place insulation mats on which the vapor barrier membrane is mounted.
Adjustable logs can be used for leveling concrete bases with large elevation differences, which are attached to the concrete surface using plastic racks.
Stand bolts can be adjusted (in the range of 10-40 cm) to create the required level of height. Adjustable with bolts bars can be quickly, without resorting to additional installation work, set over uneven floor surface. In this way, it is possible to create a precisely aligned base on which you can place a finishing floor covering.
Tools required for mounting:
Section lag depending on the span.
The work is performed in the following order:
After the lag is attached to the concrete floor, insulation can be installed between the bars.
To level the concrete base correctly and quickly, you need to get information on how to fix the logs. All stages of work should be carried out carefully, avoiding mistakes during installation of the structure. Knowledge of technology allows you to properly fix the logs to the concrete surface, preventing the device from deforming. A floor covering made on a correctly mounted bar frame will be reliable and will last for a long time.
