Abstract

The utility model relates to an enhanced composite board sectional material. The enhanced composite board sectional material comprises upper wood veneer, lower wood veneer, a core layer and reinforced ribs, wherein the core layer is arranged between the upper wood veneer and the lower wood veneer and comprises 2 to 5 bamboo core layers; the bamboo core layers are arranged in a laminating manner in the vertical direction and bonded with each other through adhesive; the core layer is arranged between the upper wood veneer and the lower wood veneer through the adhesive, the upper surface and the lower surface of the core layer are respectively wrapped by the reinforced ribs, and the reinforced ribs are glass fiber layers or aramid fiber layers; the upper wood veneer, the lower wood veneer and the core layer are identical in length, and both the upper wood veneer and the lower wood veneer are respectively an elongated wood lath. While maintaining the wood texture, capable of being nailed and planed and resisting the mildew and corrosion, the enhanced composite board sectional material has the advantages of light weight, no creep deformation, no warping and stability in size. More importantly, the enhanced composite board sectional material is high in bending resistance and impact strength, has rigidness and flexibility, can substitute the natural lumber and is applied to the field of a stress structure.

Description

A kind of composite wood plank sectional material of enhancing

Technical field

The utility model relates to a kind of architectural shape, is specifically related to a kind of composite wood plank sectional material of enhancing.

Background technology

Proposition along with recycling economy, Wood-plastic material is received people's pay attention to day by day as biomass energy and environment-friendly material, by each fields such as logistics, building, decoration, outdoor scene and office accommodation and furniture, be familiar with and use just at a terrific speed, being thought one of emerging industry with the fastest developing speed both at home and abroad.Though the physical and chemical performance of Wood-plastic material itself has obvious adjustability, compare with other structural material, still there is obvious deficiency, be mainly that bending strength is lower, there is creep and buckling deformation problem.This has just determined that these common wood plastic composites can only, for non-structure material, can not be applied to stressed structure place at present.Meanwhile, due to being widely used of wood furniture, caused falling trees in a large number, welding, has increased cost of manufacture greatly.

Utility model content

The utility model has been intended to provide a kind of composite wood plank sectional material of enhancing, and to solve the deficiencies in the prior art, the technical problems to be solved in the utility model is achieved through the following technical solutions.

A composite wood plank sectional material for enhancing, comprises overwood skin, lower wooden skin, center core layer and reinforcement, and described center core layer, between overwood skin and lower wooden skin, and comprises 2-5 layer bamboo sandwich layer; Described bamboo sandwich layer stacked on top of one another is arranged, bonding by bonding agent each other; Described center core layer is adhered between overwood skin and lower wooden skin by bonding agent, and the upper and lower surface of described center core layer is coated reinforcement all, and described reinforcement is glass layer or aramid fiber layer; Described overwood skin, lower wooden skin and center core layer equal in length, overwood skin and lower wooden skin are strip wood lath.

Further, described bonding agent is unsaturated polyester (UP) or epoxy resin or polypropylene or polyurethane.

The bamboo sandwich layer increasing in the utility model makes in section bar, not only to have timber outward appearance, but also has adopted bamboo wood to replace reel material, has reduced the consumption of timber.The utlity model has following advantage: owing to adopting bamboo wood to substitute reel material, because of bamboo wood fast growth, become a useful person soon, so a large amount of use can reduce material cost greatly, reduce the use amount of timber; Because bamboo wood itself has higher elastic performance and strength character, therefore improved elasticity and the intensity of composite wood plank sectional material.

To sum up, the utility model keeping wooden wood sense, can follow closely can dig, in fungus-proof antisepsis, there is lightweight, not creep, not warpage, dimensionally stable, the more important thing is and there is higher bending resistance and impact strength, rigidity and toughness have concurrently, can replace natural timber, for the occasion of force structure.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Reference numeral in accompanying drawing is followed successively by: 1, overwood skin, 2, lower wooden skin, 3, center core layer, 4, reinforcement, 5, bamboo sandwich layer.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, further set forth design feature of the present utility model.

As shown in Figure 1, a kind of composite wood plank sectional material of enhancing, comprises overwood skin, lower wooden skin, center core layer and reinforcement, and described center core layer, between overwood skin and lower wooden skin, and comprises 4 layers of bamboo sandwich layer; Described bamboo sandwich layer stacked on top of one another is arranged, bonding by bonding agent each other; Described center core layer is adhered between overwood skin and lower wooden skin by bonding agent, and the upper and lower surface of described center core layer is coated reinforcement all, and described reinforcement is glass layer or aramid fiber layer; Described overwood skin, lower wooden skin and center core layer equal in length, overwood skin and lower wooden skin are strip wood lath.

The above embodiment has only been expressed a kind of embodiment of the present utility model, but can not therefore be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement.These all belong to protection domain of the present utility model.

Claims
