One effective reinforcement strengthens compound bamboo cylinder plastics bio-matrix hollow beam, and its preparation method, comprises the following steps:
The first step, compound bamboo cylinder is made: 1. select the former bamboo that 3-6 is raw by Structural Design Requirement, former bamboo is softened open and flat expansion, the flat glued by bamboo sheet launched (use phenol glue or not containing the ecological glue of formaldehyde) is become wider bamboo clappers, then bamboo clappers is peeled into thinner bamboo fibre lamella; Or the former thick bamboo tube chosen is divided into the former bamboo chip of same widths and length, carry out after going blue or green de-etiolation dewatering or dry (moisture content is no more than 12%), then gluing is carried out to it and (adopt phenol glue, solid content is about 30%), under proper temperature (about 150 DEG C) and pressure (about 5MPa), be pressed into the bamboo glulam meeting Structural Design Requirement by forcing press, bamboo integration plate material is peeled into thinner bamboo fibre lamella; Or the former thick bamboo tube chosen is divided into the bamboo chip of regular length and width, be that transverse direction does not rupture, longitudinal thin bamboo strips used for weaving loosely after going blue or green de-etiolation after serrated roller rolls, the first moisture content 10% ~ 12% of thin bamboo strips used for weaving; Then the constant-pressure and high-temperature heat treatment box being placed on designed, designed carries out about 190 DEG C high-temperature heat treatment, then impregnations, and thin bamboo strips used for weaving impregnation resin content is 8% (ratio of oven dry weight), and after impregnation, thin bamboo strips used for weaving baking temperature 70 DEG C, is dried to moisture content and is no more than 12%; Thin bamboo strips used for weaving is longitudinally organized full embryo and load mould, hot pressing adopts " heat enter cold go out " technique, pressure 4. 5MPa, temperature 140 DEG C, the bamboo wood recombinant material section bar meeting Architectural Design Requirements is pressed into by forcing press, again bamboo wood recombinant material section bar is made into wider bamboo wood recombinant material sheet material, bamboo wood recombination board is peeled into thinner bamboo fibre lamella; 2. according to the cylindrical inner mold of size Selection that building needs, inner mold is that high molecule nano material makes high voltage bearing inflatable bladders, forms inner mold when producing cylinder to airbag aeration, makes the complete venting of cylinder and just can take out air bag, very convenient; 3. thin bamboo fibre lamella length direction is wound first floor along cylindrical inner mold external diameter, in this layer of rotary-cut thin bamboo plate, bamboo fibre direction is perpendicular to cylindrical inner mold length direction; 4. thin bamboo fibre lamella length direction is wound the second layer along cylindrical inner mold length direction, in the thin bamboo plate of the second layer, bamboo fibre direction is parallel to cylindrical inner mold length direction; 5. third layer is made, this layer of same first floor; 6. make the 4th layer, this layer and the same second layer of each layer backward, repeat step 3. 4., until required thickness (thickness is not less than 18mm); Whole compound bamboo cylinder each lamella length of bamboo fibre direction is mutually vertical;
Second step, is fixed on cross section centre by the internal layer compound bamboo cylinder selected and forms concentric circles with outer compound bamboo cylinder 1; Reinforcing bar or FRP muscle are evenly arranged and are fixed between outer compound bamboo cylinder 1 and internal layer compound bamboo cylinder 4;
3rd step, pulverizes particle by the plastic bottle Bottle & Can tank etc. of industry or daily life.Particle specification: length 20mm-40mm, width 2mm-6mm, thickness 0.2mm-2mm; Clean out top layer, dry;
4th step, after biomass material natural air drying or oven dry (moisture content is no more than 12%), pulverizes through agricultural hay cutter or hammer slice type beating crusher or Special grinder for disintegrating, then mills;
5th step, by even for molding powder particle and biological material glue (phenol glue or larch tannin resin glue or not containing the ecological glue of formaldehyde) mix, be filled in the space between outer compound bamboo cylinder 1 and internal layer compound bamboo cylinder 4, and vibration compacting, carry out maintenance;
6th step, maintenance is complete, is cropped neat at two ends, is required circular configuration component.
Compound bamboo cylinder 1 must possess enough tension shear strengths, and concrete value is relevant with the stress that the extraneous load that it is shared produces, and will be determined by practical structures designing and calculating; The thickness of outer compound bamboo cylinder is not less than 20mm, and the thickness of internal layer compound bamboo cylinder is not less than 18mm.
