Abstract

The utility model discloses a bamboo door. The utility model is formed by that a surface layer bamboo board, a center layer bamboo fiber board and a bottom layer bamboo board are glued in the way of thermal pressure, and the bamboo boards are processed in the ways of proof, mildew proof and fire retardation, wherein, the surface layer bamboo board and the bottom layer bamboo board are overlapped and formed from at least two layers of bamboo sheets which are crossly, vertically and horizontally. Bamboo green surfaces of the surface layer bamboo sheets are arranged outwards. The utility model has the advantages of reasonable structure, no deformation, no cracking, impact resistance, etc. under any environment. Steel bars are inserted in the center layer vertically and horizontally, which can cause the anti-theft effect to be obviously improved, and thus the utility model can be made into various anti-theft doors. Material resources of the product are abundant, and thus the utility model is an ideal substitute product of wooden doors and metal anti-theft doors.

Description

Bamboo door

The utility model relates to a kind of door leaf structure, particularly relates to a kind of high strength that adopts natural bamboo to make, the Bamboo door of high-flexibility.

Commercially available door leaf structure has two classes.One class 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, requires to concede the land to forestry, and prohibits and cuts down back China fir material shortage, has brought serious challenge to wood-processing industry.Another kind of is metal anti-theft door, though antitheft effect is arranged, easily gets rusty, and the easy cutting damage of metal oxygen welding lacks nature line look in appearance.

The purpose of this utility model provides a kind of high strength of entirely making of natural bamboo, the bamboo door of high-flexibility, and it is indeformable, do not ftracture, shock resistance, insect protected, mildew-resistant and fire-retardant, has natural bamboo line color and luster.

Above-mentioned purpose is achieved in that the utility model is by the surface layer bamboo clappers through the Vermins-proof mildew-proof flame treatment, three layers of heat pressure adhesive of central core bamboo fiberboard and bottom bamboo clappers form, wherein surface layer bamboo clappers and bottom bamboo clappers are again by the cross-laminated in length and breadth moulding of two layers or more bamboo chip, make it to possess high strength, the performance that does not chap, the bamboo strip of top layer bamboo chip is outside simultaneously, yellow bamboo face is inside, and on the bamboo strip of top layer bamboo chip, scribble layer of transparent paint (as UV lacquer or Polyurethane paint etc.), 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, return Piao and return true sense, meet people the epoch of natural colored are pursued.The utility model adopts bamboo wood to make entirely, abundant raw materials, and bamboo fibre toughness strong (its pliability is higher than 10～15 times of lumber fibres, is higher than 3～4 times of steel).Adopt the bamboo door of this practical making indeformable in any environment, do not ftracture, anti-impact force is strong.

In the above-mentioned bamboo door, there are depiction and curve modeling in its surface layer bamboo clappers and bottom bamboo clappers surface (being that door leaf is two-sided), and have window on the door leaf, be inlaid with glass or screen window on the window, according to this design feature, the utility model can be made into the bamboo carved door of various styles, villa door, European door, parlor door, kitchen door, study door, bedroom door and formula door, furniture door, shutter door, hanging box door, door pocket and full bamboo glass door etc.

Another architectural feature of the utility model is, is interspersed with steel bar in length and breadth in above-mentioned central core bamboo fibre flaggy, and steel bar is welded to one another " well " cabinet frame in length and breadth.Should can improve the shock resistance of door and window, anti-cutting performance greatly by " well " word steel frame, have good antitheft effect, can make various security door for this reason.

The bamboo fibre flaggy of above-mentioned steel frame also can adopt the intermediate hollow structure, makes security door have good sound insulation, heat insulating function.

As seen from last, the utility model can be made into various Bamboo door and various full bamboo security door.Full bamboo security door is a bamboo wood and the combining of steel, and particular structure makes door leaf have good antitheft and decoration result, has reduced finishing and has invested, and has saved timber and steel.Bamboo door is abundant with its raw material resources, and bamboo fibre toughness becomes the ideal substitute of Solid Door by force.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 6000N

6, impact strength is greater than 137KJ/m;

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

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

9, radially flexural strength greater than 58MPa.

The utility model product all through dipping insect protected moth-proof and mould-proof and flame treatment, has good Vermins-proof mildew-proof effect, and the fire prevention index reaches national B1 level fire-protection standard.

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