Abstract

The utility model discloses a composite floor board, consisting mainly of a woody decoration layer, a high density plate-core layer, and a woody balance layer from top to bottom, the utility model is characterized in that long grooves distributed in parallel are arranged on the high density plate-core layer, the direction of the long groove is orthogonal with the fiber directions of the woody decoration layer and the woody balance layer, a woody insert lath is provided in the long groove, the fiber direction of the woody insert lath is identical with the direction of the long groove. The utility model increases the strength, lowers the cost and maintains the comfortableness of the wooden floor board, in the meantime, avoids the problems of being easy to deform and crack, thereby being suitable for the practical application.

Description

Composite floor board

Technical field

The utility model relates to a kind of multi-layer composite floor, is specifically related to a kind of composite floor board with wood flooring texture.

Background technology

In the prior art, composite floor board is owing to have advantages such as cost is low, not yielding, and is widely used.Present composite floor board, modal is consolidated floor, it adopts high-density plate usually is sandwich layer, utilizes facing paper and abrasion-proof paper impregnation to form decorative layer and wearing layer thereon, then makes balance layer with balance paper in the bottom surface.Yet, to compare with wood floors, when walking on consolidated floor, sound is bigger, simultaneously, also lacks flexibility, and comfort level is not enough.

For overcoming these shortcomings, consider to adopt plank and high-density plate compound, it promptly is sandwich layer with the high-density plate, wooden top layer is set thereon, and it also is provided with layer of wood down, and the material that has wood grain more attractive in appearance is adopted on top wooden top layer usually, the surface can be painted, play attractive in appearancely, improve the effect of comfort level, beneath layer of wood then plays buffering, alleviates the effect of sound.Yet after actual fabrication, because layer of wood has fibre structure, the layer of wood for thin easily deforms in the direction that is parallel to fiber, thereby causes the distortion on floor, has influenced the actual use of this class composite floor board.

Summary of the invention

The utility model purpose provides a kind of plank and the compound floor of high-density plate, and it should be not yielding when having the apparent and comfortableness of wood flooring.

For achieving the above object, the technical solution adopted in the utility model is: a kind of composite floor board, mainly constitute from top to bottom by wooden decorative layer, high-density plate sandwich layer and wooden balance layer, on described high-density plate sandwich layer, offer the elongated slot of parallel distribution, the machine direction quadrature of the direction of described elongated slot and wooden decorative layer and wooden balance layer is embedded with the machine direction wooden filler rod consistent with the elongated slot direction in the elongated slot.

In the technique scheme, between described each layer, can connect, the resin impregnation ply of paper also can be set, each layer closely be connected with pressure sintering as articulamentum by adhesive layer.

In the technique scheme, the distribute bits of elongated slot is equipped with two kinds, and one, the opening of described elongated slot are arranged in the one side that height degree plate sandwich layer and wooden decorative layer have a common boundary; Perhaps, its two, the opening of described elongated slot is arranged in the one side that height degree plate sandwich layer and wooden balance layer have a common boundary.

In the technique scheme, the degree of depth of described elongated slot be the high-density plate core layer thickness 1/3 to 2/3 between.

Not yielding for guaranteeing the floor, the distance between adjacent elongated slot is between 5 centimetres to 20 centimetres.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model has been offered elongated slot in the high-density plate sandwich layer, in elongated slot, be provided with wooden filler rod, thereby can avoid the flexural deformation on floor, prolong floor application life;

2. the utility model makes the composite floor board of plank and high-density plate be suitable for practicality, thereby when gaining in strength, reduce cost, keeping the wood flooring comfortableness, has avoided the wood flooring problem, the problem includes: problem yielding, cracking.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: shown in accompanying drawing 1 and accompanying drawing 2, a kind of composite floor board, mainly constitute from top to bottom by wooden decorative layer 1, high-density plate sandwich layer 2 and wooden balance layer 3, on described high-density plate sandwich layer 2, offer the elongated slot 4 of parallel distribution, the machine direction quadrature of the direction of described elongated slot 4 and wooden decorative layer 1 and wooden balance layer 3 is embedded with machine direction and elongated slot side 4 to consistent wooden filler rod 5 in the elongated slot 4.

Wherein, the opening of described elongated slot 4 is arranged in the one side that height degree plate sandwich layer 2 and wooden decorative layer 1 has a common boundary; The degree of depth of elongated slot 4 be high-density plate sandwich layer 2 thickness 1/3 to 2/3 between; The distance that adjacent elongated slot is 4 connects by adhesive layer between described each layer between 5 centimetres to 20 centimetres.

Embodiment two: shown in accompanying drawing 3 and accompanying drawing 4, a kind of composite floor board, from last and on mainly constitute by wooden decorative layer 1, high-density plate sandwich layer 2 and wooden balance layer 3, on described high-density plate sandwich layer 2, offer the elongated slot 4 of parallel distribution, the machine direction quadrature of the direction of described elongated slot 4 and wooden decorative layer 1 and wooden balance layer 3 is embedded with the machine direction wooden filler rod 5 consistent with elongated slot 4 directions in the elongated slot 4.

Wherein, the opening of described elongated slot 4 is arranged in the one side that height degree plate sandwich layer 2 and wooden balance layer 3 have a common boundary; The resin impregnation ply of paper is set as articulamentum between each layer, each layer is closely connected with pressure sintering.
