Laminating wooden floor with prestress structure

Abstract

The invention provides a laminated wood floor of a prestressed structure. The floor is formed by bonding at least an upper medium-density fiber board and a lower medium-density fiber board at high pressure and low temperature. At least one spatially structured high-elasticity plastic component is clamped between the upper medium-density fiber board and the lower medium-density fiber board. The high-elasticity plastic component is embedded in a groove which is arranged in at least one medium-density fiber board; the high-elasticity plastic component is a spatially structured frame composed of a longitudinal rib and a horizontal rib, and the longitudinal rib and the horizontal rib form an radian which bulges upwards or downwards, and the high-elasticity plastic component is arranged between the upper medium-density fiber board and the lower medium-density fiber board to form a core board. The laminated wood floor has the advantages of good structural strength and stable structural properties, effectively ensures that the floor is not affected by environmental change during use, prolongs the service life, provides possibility of mass product processing, greatly saves wood resources, reduces the cost and the like.

Description

technical field [0001] The invention relates to a laminated wood floor, in particular to a wood floor with at least two upper and lower layers of medium-density fiberboards composited to form a core layer, and belongs to the technical field of floor manufacturing. Background technique [0002] In the prior art, the technology of using medium-density fiberboard (HDF) to produce floors through compounding is already a mature flooring manufacturing technology, but the composite flooring mainly made of medium-density fiberboard (HDF) still has bending resistance and The problem of poor elasticity, in order to overcome the problem of HDF bending resistance and poor elasticity, some structural technology is usually used to solve it. Now there are two known such technologies. One is the rib structure in the HDF plate. , the second is to sandwich wooden horizontal veneers between two HDF boards, that is, the sandwich structure. The core purpose of its technology is to enhance the be...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies, and provide a laminated wooden floor with prestressed structure, which adopts a new concept, designs HDF prestressed structure technology, comprehensively improves the bending resistance of HDF, and completely solves the problem of HDF boards. The floor deformation and other problems caused by insufficient bending resistance in the production of wooden floors meet the functional and quality requirements of floor products, expand the use range of HDF boards, and propose a new idea and method for the floor manufacturing industry
