Description

Bamboo door

The utility model relates to a kind of door leaf structure: be particularly related to a kind of high strength of natural bamboo and this material be combined into, Bamboo door of high-flexibility of adopting.

Commercially available door leaf structure is traditional Solid Door, generally adopts wooden soft China fir to make, and is yielding, easy to crack, and China fir normally is grown among the forest of height above sea level more than 1000 meters, and country prevents erosion in order to protect the ecological homeostasis, has prohibited the lumbering material.Require to concede the land to forestry, prohibit and cut down back China fir material shortage, and the producer of the lines of production, entirely by import, cost is very high.The tailing of timber can't utilize.

The purpose of this utility model provide a kind of complete with natural bamboo be the door the panel base material, central core is the leftover bits and pieces of timber, it is 30cm that bamboo chip becomes width, the high strength that the wood chip of thickness 2cm forms with the compound heat pressure adhesive of bamboo chip, the Bamboo door of high-flexibility.It is indeformable, do not ftracture, shock resistance, anti-electricity, mildew-resistant, has natural bamboo line color and luster.

Above-mentioned purpose is achieved in that the utility model by the surface layer bamboo clappers of handling through Vermins-proof mildew-proof, and middle level timber leftover bits and pieces and small dimension wood through hacking the same wide equally thick wood chip with bamboo chip, add that three layers of compound heat pressure adhesive of bottom bamboo clappers form.From and make that door leaf is two-sided to present natural bamboo line color and luster.The bamboo line is clear, attractive in appearance, returns Piao and returns true sense, meets people the epoch of natural colored are pursued.The utility model adopts bamboo wood and wood composite to make entirely.Reduce the cost of timber system door, carry out comprehensive development and utilization bamboo wood resource.

Above-mentioned Bamboo door, the seamed edge of basic unit's face bamboo board and bottom bamboo clappers surface (being that door leaf is two-sided) and door heart frame has curve modeling and pattern engraving.According to this design feature, the utility model can be made into the bamboo wood composite carved door, villa door, European door, parlor door, kitchen door, study door, bedroom door, furniture door of various styles etc.

The physical performance index of Bamboo door of the present utility model is:

1, the coefficient of shrinkage: vertically less than 0.10, laterally less than 0.01;

2, moisture content 10%-12%:

3, bulking coefficient: vertically less than 0.52, laterally less than 0.80;

4, density is about 0.746g/cm;

5, hardness is greater than 6000IV;

6, impact strength is greater than 137kj/cm;

7, crushing strength parallel to the grain 90MPa (be about China fir 1.5 times);

8, crushing strength parallel to the grain 180MPa (be about China fir 2.5 times);

9, radially flexural strength greater than 58MPa.

The utility model product has good Vermins-proof mildew-proof effect through dipping Vermins-proof mildew-proof and flame treatment, and the fire prevention index reaches national BI level fire-protection standard.

Further specify the utility model structure below in conjunction with Figure of description.

Fig. 1, be the utility model Bamboo door structural representation

Fig. 2, be the utility model Bamboo door cross-sectional view

Bamboo clappers raw material of the present utility model is made with the high-quality bamboo more than 5 years, hack one and go joint to go yellow one slightly to formulate to such an extent that slightly create bamboo chip through cutting material one, to slightly create bamboo chip again and carry out Vermins-proof mildew-proof bleaching flame treatment and burin-in process, stand-by bamboo chip is slightly formulated in oven dry then.Utilize the leftover bits and pieces of timber to hack the specification the same with bamboo chip with rim charge again, its water content is 10%---20%, be composited through hot press on request.Become the door blank at last on demand again.

Embodiment 1:

Present embodiment is a Bamboo door, sees Fig. 1.It is formed by surface layer bamboo clappers 3 central core planks 1 and 2 three layers of compound heat pressure adhesive of bottom bamboo clappers.As mentioned above, the bamboo chip in the bamboo clappers is all through chemical Vermins-proof mildew-proof flame treatment, and the central core plank is to utilize wooden waste after the processing to hack to form the compound bamboo-wood composite board that all adopts hot press applying glue high-temperature high-pressure craft to be made into various door blanks of its hot pressing.

Embodiment 2:

With the compound sheet material of bamboo wood, make the Bamboo door of various different shaping uniquenesses; The two-sided bamboo line color and luster that presents of door leaf, two-sided sanding, and, make this product meet international ISO9002 standard green product standard at the two-sided last layer environmental protection paint that is coated with.
