Description
Technical field
The utility model relates to a kind of anti-deformation wood core floor.
Background technology
Under the situation of high-grade solid wood resource scarcity, have employed solid wood web as core, upper and lower bonding wooden skin, manufactures three-layer solid wood floor.
Three-layer solid wood floor (long 900--1880mm, wide at 122--220mm) is floor core in the middle of it.In order to improve the resistance ability of core, usually long strip type wooden unit (long 125-230mm, wide 25-40mm, thick 10-18mm) transversely arranged assembly is made into core by bonding, 0.1-1mm gap is left between rectangular wooden unit is transversely arranged, its objective is in order to timber when shrinking or expand, play and eliminate distortional stress effect, this gap penetrates into the two ends of plate core.Core is pasted surface layer (bonding with longitudinal line wood skin with the wooden skin of higher gears), wooden cortex (adopt longitudinal line wood skin bonding), defines three layers or multi-layer floor material carrys out Manufacture of Floor.Because core used, surface layer wood chip, backboard exist the situation of different density, moisture content, wettability power, anti-equilibrium deforma ability of its performance is not identical yet.
Above-mentioned three-layer solid wood floor core adopts horizontal assembly, floor is being carried out in length and breadth after tongue-and-groove processing, all there is a lot of assembly grooves or sawing groove (vertical channel or upper and lower skewed slot) in longitudinal (or horizontal) tongue-and-groove, and adjacent assembly groove or sawing slot pitch are from shorter, be easy to the reel fracture causing local, snap close edge, both affected flooring look, the splicing lock having influence on again floor buckles soundness.
Because its edge of pure wooden floor, market does not exist assembly groove or sawing groove, so snap close is bright and clean, good looking appearance, splices easy for installation and deeply to like by customer, but pure wooden floor exists and holds yielding problem, is unwell to floor heating and uses.When solid wood resource is comparatively in short supply, cause wooden floor on the high side, the consumer group receives restriction.
In order to solve the defect of above-mentioned three-layer solid wood floor, liking of the wooden floor consumer group can be met again, adopt again existing patented technology both at home and abroad, batten framework is inlayed again in the surrounding of core, surface layer, backing layer wood skin are pasted the outer rim of batten framework, after surrounding is processed into tongue-and-groove, there is not assembly groove or sawing groove, floor tongue and groove is bright and clean; Compare three-layer solid wood floor structure in the past, aesthetic reaches wooden floor.But turn increase the making of wooden frame with bonding, complex process, cost increases, and causes production capacity on the low side, still constrains production industrialization, form automated production difficulty.
Summary of the invention
In order to solve the problem, the utility model provides a kind of anti-deformation wood core floor, has high strength, feature that non-deformability is strong, and wood limit, snap close position phenomenon of rupture not easily occurs, and Stability Analysis of Structures, snap close is firm.Without the need to bonding making wooden frame separately, and industrialization automated production can be realized, meet the effect of wooden floor, also be suitable for floor heating and install, save timber, improve production capacity, reduce cost of production.
