Parquet (Fig. 8) is a homogeneous strips of fine wood and high-grade timber. Plank parquet have both parties costal ridge and the other two sides - the groove. Trims release guys: with the right and left crest length 150-450 mm, with gradation of 50 mm. Width gtanok 30-60 with a step of 5 mm. Strips of hardwood have a thickness of 16 mm, and softwood-19 mm. Ridge has a thickness of 4.9 mm and supports the edge of the front plate of 5 mm. Groove width of 5.2 mm recessed in the bar by 6 mm. At the indicated amounts parquet coating has equal strength and in the middle of the slats, and at the connection. Above the groove and the ridge is a layer of wear, abrasion during the operation of sex. The thickness of this layer of solid hardwood 7 mm for conifers - 8,5 mm. To ensure a tight connection between the slats are made small, 1 mm, undercut side edge of the wear layer of 1 mm above the crest. During renovations in older homes can meet other flooring types. Parquet planks with grooves on all four edges (Fig. 9 a) are called "specialists", as it is intended only for the laying on nails and loose spikes on a wooden base. For laying on hot mastic produced flooring with beveled edges (Fig. 9, b). For laying a layer of hot asphalt intended parquet "with fold (Fig. 9, c), the lower part of which had a beveled edge. Mosaic (typesetting) parquet - a square-shaped plates, recruited from small parquet planks of the same size (Fig. 10). Strap affixed to the face sack paper or other flexible and durable material, which after laying flooring are easily removed, moistened with water. Dimensions of plates and 400X400 600X600 mm. Plank of which are gaining flaps may have a length of 100-200 mm and a width of 20-45 mm. The thickness of the planks of wood hardwood 8 mm, made of pine and larch 12 mm. Already begun to apply flaps mosaic parquet, glued on rubber base. The appearance of mosaic parquet on elastic foundation due to the desire to improve the quality of soundproof floors. Parquet panels (Fig. 11) are square elements of the covering of two types: with the grooves, with tongue and groove. Parquet panels - two-ply construction. The lower layer - the base (foundation) consists of a square frame (stud) 22 mm thick. Rail is filled one row of planks the same thickness. To connect the piping and filling using water-resistant synthetic adhesives. Shield of the first type has all four edges of the binding groove depth of 14 mm and 8 mm wide, not reaching the corner of 100 mm. Rallying flooring is carried out on loose spikes. Shield of the second type on the two adjacent edges have grooves, but on the opposite - combs. Face shields cover both types is identical and consists of a rectangular parquet slats securities or high-grade timber, tightly glued to the ground. The length of the straps 100 and 200 mm, width 20-45 mm, 8 mm. The total thickness of the shield 30 mm. Full dimensions of the square board 800X800 mm, half-400X400 mm. Hardwood boards (Fig. 12) - is double-layer wooden structures. The lower layer - the base of the planed slats or planks of low-grade wood, the top layer - parquet made of rectangular strips of valuable species. Both layers are glued together with waterproof adhesives based on synthetic resins. Upper plane of the floorboard is called the front plane, the long sides - edges, and short - ends. Parquet board rack in the lower layer at one edge and one end of the 0 has a groove and on opposite sides - the crest. Tongue and groove with the exact dimensions, are processed so that the connection boards were the most dense, and solid flooring not have even the slightest imperfections in the joints of adjacent boards operating under the influence of concentrated loads. Board used for the base, 20-30 mm should be dead-end longitudinal cuts to prevent warping the base when its moisture content. Hardwood plank across the top layer have the rack base. For the device ground under hardwood planks and parquet panels use wood of pine, spruce, fir, cedar, larch, as well as small amounts of birch, alder, aspen and poplar. Strips for parquet made from oak, beech, ash, maple, elm, elm, elm, beech, locust, honey locust, birch, pine, larch. Front surface of parquet flooring and paneling cover the parquet lacquer in the factory. Parquet comes parties, each of which includes a product of the same type of facial covering one picture of the wood of the same breed. One party is enough to cover the parquet floors with total area of ??not less than 100 m2. Plant or facilities, supplying builders flooring, guarantee its quality and conformity to technical conditions, as evidenced by an entry in the passport accompanying the party. Before laying the flooring should again check the quality by sampling inspection. If this question arises under flooring standard, then hold control check of the entire party in the presence of delivering plant and the construction laboratory. During transportation and storage flooring must be protected from moisture, direct sunlight, pollution and mechanical damage. In addition to the parquet parquet layer uses a variety of other materials. Baseboards and fillets nailed between the edge of the floor and the wall around the perimeter of the premises to close the gap left at laying the parquet. Plinths (Fig. 13) and fillet (Fig. 14) made of pine, larch, cedar, spruce and fir. In areas with humidity less than 70% can be applied moldings and fillets of beech, birch, alder, linden, aspen and poplar. Hot bituminous mastics used to label mosaic parquet, and repair works for the label in order to improve sound insulation fiberboard on slabs and asphalt screed insufficient strength. The main advantage of hot mastic - Fast curing: by svezheulozhen-nomu the floor area you can walk after 1-2 min. However, the wide application of hot mastic prevent significant shortcomings. Due to the high operating temperature (160-180 ° C) with them is dangerous work. To warm up the mastic should be a lot of heat or electricity. While maintaining the mastic in working condition distracted people from the basic processes, in addition, require special bottles and flasks. The basic material included in these pastes are building bitumen BN-111 and BN-IV. Introduction to the postmark of different fillers can reduce the operating temperature and make them less hazardous. Prepare mastic centrally and delivered to construction sites in a special asphalt distributor. Cold mastic is prepared on the construction bitumen BN-111 or BN-IV in the factory. These pastes harden through the evaporation of solvents - gasoline, ethyl acetate, mineral spirits, etc. The most common mastic "Bisky, bitumen-rubber, Ku Maroon neyritovaya adhesive sealant, KH-2. Cold mastic hardens 1-3 days. Therefore, to walk on the parquet floor is permitted only through the day, and handle (tsiklevat, polish) - no earlier than 3 days. Primers used to create a watertight film improves the adhesion of bituminous mastics with the ground. Primers are prepared on-site bitumen BN or BN-III-IV, gasoline or kerosene. Parquet is laid on a fully dried primer.
