Abstract
The utility model discloses an anti-warping composite floor which is composed of a face plate, a middle plate and a base plate, wherein the face plate and the base plate are pasted on the front and the back sides of the middle plate, wherein places on the front side of the middle plate, 10-50 mm away from the ends of the middle plate, are transversally provided with grooves every 5-100 mm apart. Each groove has a single-side depth of 0.5-10 mm. The back side of the middle plate is symmetrically or asymmetrically provided with the same grooves. The grooves arranged on the middle plate effectively destroy the fiber stress and the volume expansion coefficient of a wood floor, and reduce the inner stress of the composite floor body to the minimum. Meanwhile, both sides are transversally provided with the grooves, so the composite floor has good toughness, keeps the original level state after laid many times, and avoids longitudinal deformation and warping problems generated in the production and the use process of the floor, so that the composite floor has a smooth stable board surface.
Description
Technical field
At present, the composite floor board that uses and sell on the domestic and international market, because the skewness of irregular machine direction of timber itself and timber bulk density, make multiple floor produce and use the internal stress of timber to can not get discharging, cause the buckling deformation on floor, influence the use on floor and attractive in appearance.
Summary of the invention
The purpose of this utility model is the composite floor board that a kind of anti-warpage is provided in order to overcome the deficiencies in the prior art.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: constitute whole floor by panel, middle plate and base plate, panel and base plate be bonded in plate just, the back of the body two sides on, its on middle plate front apart from the every interval 5~100mm in 10~50mm place, plate termination laterally have groove, the single face degree of depth of groove is 0.5~10mm, and middle backboard is in the face of claiming or asymmetricly having a same groove.
Above-mentioned groove and middle plate longitudinal angle are between 30 °~90 °, and promptly the length direction of groove and composite floor board forms certain included angle, and angle is between 30 °~90 °.
Owing to adopt technique scheme, on the middle plate substrate two sides of composite floor board, have groove, this groove has destroyed the fiber stress of wood floors and the coefficient of expansion of volume effectively, makes composite floor board body interior stress drop to minimum.Simultaneously, two-sided transversal slotting has excellent toughness, repeatedly mats formation still to keep original smooth.Produce the problem of longitudinal strain and warpage when having avoided the floor, thereby make composite floor board plate face smooth stable in process of production with use.
