Abstract
The utility model relates to hollow chamfered joint recombination bamboo structure wood. Recombination bamboo, adhesives and veneer are used as raw materials, the hollow chamfered joint recombination bamboo structure wood is manufactured through chamfered joint lengthening and recombination of the recombination bamboo, a hollow structure is adopted, and the problems, caused by the recombination bamboo being the structure wood, of performance excess and large self weight are greatly solved. The veneer and a paper plate are arranged at the glue connecting position, and the technical bottleneck that the recombination bamboo is prevented from becoming the structure wood due to strength attenuation caused by bad gluing in the secondary recombination process is effectively solved. The hollow chamfered joint recombination bamboo structure wood can be used on beams, columns, furniture and large-size outdoor floors and the like.
Description
Technical field
The utility model belongs to wood-based plate and the manufacturing technology field thereof in industry of artificial boards, is particularly useful for mechanical property requirements high, building and the Engineered Wood Products such as the beam that specification is large, post, furniture and floor.
Background technology
Recombined bamboo is through after discongesting and forming fibrillatable bamboo veneer, through super-dry, impregnation, a kind of novel building and the Engineered Wood Products that process of the operations such as dry, assembly and gummed again with bamboo wood.More than the MOR of this material can reach 350MPa, more than hot strength can reach 360MPa, more than compressive strength can reach 140MPa, elastic modelling quantity can reach 27GPa[in Wen Ji. the progress [J] of China's high-performance bamboo base fibrous composite. and timber industry, 2011,25 (1): 6-8,29], have good physical and mechanical property, Recombined bamboo is directly used in and makes beam, post, furniture and floor etc., often cause intensity superfluous, cause waste; In the process that forms, the density of this material reaches 1.05～1.30g/cm
3,, because the material deadweight is larger, easily cause and use inconvenience.
Chinese patent 201010243351.7,201020279829.7,201020279815.5 provide a kind of employing undersized log to make undersized log recombination structure material and manufacture method thereof by mitered or mitered, adopted this method undersized log can be processed into the recombination structure material of large specification.But this technique forms when secondary gluing glue-line, its glue performance is unstable, has certain variability, some sheet material glue-lines phenomenon such as may occur ftractureing, come unglued; The problems such as bonding strength is low, the physical mechanics property loss of energy is large may appear in other sheet materials.By analyzing, the main cause that causes above-mentioned phenomenon and problem is that spot gluing is bad.
Summary of the invention
The purpose of this utility model is to improve the deficiency in existing technology, and hollow mitered Recombined bamboo structural wood is provided, and makes its physical and mechanical property meet the requirement of structural wood performance.
For achieving the above object, the utility model is taked following technical scheme:
The utility model provides a kind of hollow mitered Recombined bamboo structural wood, it comprises two front plate, two side panels and adhesive, two front plate and two side panels compose the hollow square column that cross section is square or rectangular mutually, described front plate and side panel are that the weld of two front plate of described mutual gummed and two side panels is an angle of 90 degrees or miter angle by the vertical mitered spreading of Recombined bamboo process; Adhesive used is the agent of resorcinol gluing or aquosity polymer isocyanic ester adhesive.
Described a kind of hollow mitered Recombined bamboo structural wood, also include veneer, between two front plate of described mutual gummed and side panel junction, one deck veneer is set, and the thickness of described veneer is 0.1-1.5mm; Be provided with adhesive layer between Recombined bamboo and veneer, adhesive used is the agent of resorcinol gluing or aquosity polymer isocyanic ester adhesive;
Described a kind of hollow mitered Recombined bamboo structural wood, also include cardboard, the Recombined bamboo of described vertical mitered spreading is provided with a layer paperboard between the composition surface of Lengthwise joint, be provided with adhesive layer between Recombined bamboo and cardboard, adhesive used is the agent of resorcinol gluing or aquosity polymer isocyanic ester adhesive.
The hollow mitered Recombined bamboo structural wood that the utility model provides, adopt the hollow square column structure, reduced significantly the density of material, and production technology is simple; Reduce costs; The ratio of strength to weight is large.
In addition, but the compressible deformation of one deck is set between the Recombined bamboo high in hardness, that strength and stiffness are large, thickness 0.1-1.5mm veneer veneer, this splicing face structural design, but take full advantage of the good wetability of veneer, permeability, gummed and the characteristics such as compressible and deformation, utilize veneer veneer deformation behavior, can effectively fill up the gap that forms due to the cemented surface injustice between the Recombined bamboo that hardness is high, strength and stiffness are large, thereby increase effective cemented surface; Utilize the good wetability of veneer veneer and gummed property, can form good cemented surface with Recombined bamboo, improve glue performance; When secondary gluing, utilize permeability and the compression performance of veneer, under the effect of exerting pressure, make veneer veneer compression compact, simultaneously, the agent of resorcinol gluing or aquosity polymer isocyanic ester adhesive can be penetrated in the veneer veneer fully, with the veneer veneer, the gummed reaction occur, thereby form the compressed wood close with the Recombined bamboo performance.This splicing face structural design, utilized dexterously the characteristic of Recombined bamboo and veneer veneer, make large specification Recombined bamboo bonding layer after gummed meet the rigidity approximately equal of bonded part, the traditional classical splicing face gummed theory that thermal expansion and moisture expantion are close, solved again the adhesive defects such as Recombined bamboo comes unstuck, crack, space, bondline thickness variation.
The hollow mitered Recombined bamboo structural wood that the utility model provides when Lengthwise joint, is provided with a layer paperboard between the composition surface of Lengthwise joint, cardboard is basic identical in the effect of weld and above-mentioned veneer veneer, repeats no more here.Why when Lengthwise joint, select cardboard, reason is as follows: compare with the veneer veneer, but except good wetability, permeability, gummed and the characteristics such as compressible and deformation, flexibility and the plasticity of cardboard are better.Usually miter is special-shaped curved, and cardboard can design according to the shape of miter, thereby the splicing face of making is more identical, can reduce to greatest extent come unstuck, the adhesive defects such as crack, space, bondline thickness variation.
The hollow mitered Recombined bamboo structural wood that the utility model provides is in Lengthwise joint and restructuring recombination process, adopt the namely two component isocyanate adhesives of cold curing adhesive or resorcinol adhesive, can according to target product need to be compound in the restructuring of length and thickness direction, meet the large-sized specification requirement of structural wood.
The hollow mitered Recombined bamboo structural wood that the utility model provides, in the Recombined bamboo manufacture process, select impregnating phenolic resin or dipping to use Lauxite, makes bamboo bundle or wood bundle reach even impregnation, thereby obtain the Recombined bamboo of stable performance.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is not limitation of the utility model, every any this area of carrying out according to the utility model disclosure be equal to replacement, all belong to protection domain of the present utility model.
