Construction parquet wood surface construction called parquet wood surface layer should refers to the use by the plant processed hardwood floor fight flowers were laying on the floor. The method of construction should take double laying wood floor construction, the upcoming fight flowers flooring nailed hair on the floor - nail knot style; flooring flowers can also be used to fight the asphalt binder or adhesive paste directly on the cement grassroots - BONDED. 1. Material Requirements parquet wood surface layer using wood species, design requirements should be selected. When the design requirements Chongqing No wood, apply ash, walnut, oak and other fine texture, easy decayed wood cracking and made tongue and groove, cut or flat seams El flowers floor fight, which kerf Peace head seams wooden plates suitable for asphalt binder or adhesive paste, tongue and groove joints of wooden plates suitable for nail knot-type construction. Prefabricated wooden parquet floorboards unit should be waterproof and bacteria using glue seams should be aligned, gluing wood floors should be closely Chongqing, Chongqing, the gap should not exceed 0.2 mm wood door price, dimensions should be accurate, surface should be smooth. 2. Laying (1) nail knot style: above ground in building grassroots install wood floor joists and nail shop hair. Wool has been the staple good to be copied flat floor surface should, if necessary, should be appropriately planing, can achieve the requirements set flatness after laying asphalt paper or felt, and then press the desired design mosaic pattern puzzle nail shop, parquet flat pattern forms such as square format, seats grain type, herringbone style, scattered long ladder pavement type and so on. For more complex mosaics, are advised to try to fight the test shop, according to the design should pay attention to while using the same trim flooring materials processing. When the length of the parquet wood is not greater than 300mm, the sides should be nailed two nails; the length of more than 300 mm, 300mm should be increased every one nail, nail a nail tip should be. (2) bonding formula: bonded floor tiling flowers before the fight, should be numbered according to the designs together to fight the test after test plate size shop, adjusted to meet the requirements, according to numbers from the room when the Stones Central gradually expand to four weeks. Chongqing bonding materials used in wood-plastic composite materials, which can be asphalt binder can also be a variety of adhesives. From the development process throughout the decade, the wood and wood products is the development of ecological continuous extension and development scientists in North America 1. waste wood flour and plastic continue synthesis output of the first generation of ecological wood beginning, this technique has been extended development of. From North America to Europe and gradually developed until Germany to introduce China, which just five years. Ecological wood in China has developed into three factions, led by Guangdong Foshan, Linyi, Shandong, Jiangsu and Zhejiang provinces and industrial chain. 2. For the purposes of product development, Guangdong ecological wood manufacturers for product development and quality control aspects are better than other regions, which has a great many reasons to participate in scientific research have with local colleges. For example: Located in Guangzhou, South China University of Technology, there were special projects on wood, eco-wood research. With the involvement of research institutions in the development of eco-wood products are also a number of manufacturers to the third generation of products. One of the representatives are: Foshan ecological wood, as well as ecological wood Guangzhou, Shenzhen and ecological wood, Guangdong ecological wood launched the third generation of ecological wood in early 2010, through the production process to further improve the product surface texture contrast, while increasing the feedstock process improvement, to change the ecological wood rough texture. By itself, the latter advantage in the timber industry, the adoption of new technologies to develop a new generation of eco-wood. 3. prospects, industry structure. 2010 original, with the rise in raw materials, resulting in increased production costs. The R & D capabilities and production scheduling has strong ecological wood Guangdong enterprises, and gradually dominate the race. Part of the production capacity of small and medium enterprises will gradually withdraw from the weaker the chain. Competition between enterprises will increase, between the large-scale research and development enterprise product homogeneity weakened. The new round of technological innovation will start, but the majority of people will be benefited from the use of eco-wood.
