Parquet flooring

When installing parquet floors in the small-sized panels for alignment poured a layer of sand on which are placed strips of insulating and finishing fiberboard. Pads are placed on wooden logs, and on them - hardwood boards (Fig. 25). With the smooth surface of the panel size for the room sand bed is not needed and soundproof pads are placed on the overlap. In this case, use more subtle lags. The most common are two constructions of reasons: 1) using polystyrene log, glued with hot bitumen, and 2) the use of sand backfill and diluted (in 800-1000 mm) wooden log, drowned in the sand. In the second case only lags associated hardwood flooring boards into one, and support for them is virtually incompressible sand. The distance between the beams 400 - 500 mm. First stack of Lighthouse lags every 2 m, and then the intermediate every 40 m. Flooring begin with a sandy backfill alignment in terms of rake and pinion in the direction away from the window to the door. Parquet boards lay perpendicular to the sleepers (the first - always on the cord to the wall crest at a distance of 10 mm from it) and nailed to each lag (Fig. 26). Follow parquet boards must be tight fitting to each other, to comb all included in the slots. To the floor was not unsteady, all Mechanical joints of boards arranged on the joists. Neshpuntovannye compound boards are not allowed. Hardwood planks and joists should not touch the walls, but the gap must not exceed 10 mm. Not allowed overhangs parquet over 100 mm in this case placed additional lags. Parquet planks plank parquet two - 3rd and 4 th digits. Laying start from the top floor and finish on the bottom. Quality floorings checked daily and acceptance of work. Horizontality and flatness of the floor in all directions, controlled by a two-meter rack level. Gaps between the rack and the floor area of ??more than 2 mm and ledges between the edges of adjacent boards are not allowed.
