Long gap between the three wood approach: taking into account drainage, cleaning and minor thermal expansion, contraction and other reasons, wins dimensional profile installation, edge to edge, you must leave appropriate gap between the head to head. Edge to Edge: wins Dimensional Cutting edge to edge between the requirements of ≥4 mm: When installed in a cold climate, ≥4 mm clearance requirements. Head to head: the gap between wins dimensional profile head to head size depends on the length of the sections, the temperature during installation, the thermal expansion coefficient profiles (ζ≈0.9 × 10-4), as well as local highest possible temperature. Head to head clearance calculation: For a L-meter-long sections, local highest possible temperature within one year Tmax, the temperature at installation is T, then install the root profile head should be kept gap Δ L = ζ × (Tmax? -T) × L. For example: a 2 m long profile, installation day temperature is 10 ℃, wood flooring production address, the hottest day of the year the temperature is 40 ℃, then install the root profile head should be kept gap: Δ L = ζ × (? Tmax- T) × L = 2000 × (40-10) × 0.9 × 10-4 = 5.4mm wood floor installation diagram: 1, the installation base surface leveling. 2, under normal circumstances, wood profile installation requirements keel span of not more than 350 mm, Hunan wood floors, and single profiles to use at least three keel. Solid wood flooring keel span requirement ≤ 400mm; but when the floor thickness is less than 25mm keel span requirement ≤ 250mm; hollow wood floor keel span requirements ≤ 250mm. Also keel span depends on the thickness of the floor, in the case of hollow floor, the wall thickness should also consider the size, thickness and the thickness of the floor directly affect the keel of the span, the installation in strict accordance with the manufacturer regulations. 3, durable stainless steel self-tapping screws, wood is the preferred installation profile; screw lengths with different thicknesses vary, generally keel depth 20mm screw-driving as a base to calculate the length of the screw, wood flooring wholesale, do not tighten the screws The tight. 4, wood floor planks supporting the fasteners allow installation is very easy, supplied with fasteners and screws, fasteners will naturally make the formation of a gap between the two floors, do not squeeze the fastener to narrow space. WPC production addresses three long building materials (online consultation), Hunan wood floor provided by the Chongqing Municipal Building Materials Co. three years. Chongqing City for three Building Materials Co. (www.cqjsmsjc.com/) Chongqing Liangping County, building materials processing leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the three years leading building materials with the staff warmly welcome all inquiries negotiations to create long three building materials better future.
