Abstract
The invention discloses a method for producing a high-strength wood structure engineering material. The method is characterized by comprising the following steps of: before gluing split boards or squared timbers, carrying out laser punching treatment on the gluing surface of the boards or squared timbers; punching micro holes in a certain depth and a certain diameter on the gluing surface of the boards or squared timbers; and then gluing, assembling blanks and cold press forming. After forming, effective glue nails are formed on the gluing interfaces of the boards or squared timbers, so that the aim of enhancing the strength of the wood structure engineering material is achieved. According to the method disclosed by the invention, the effective glue nails are formed on the gluing interface, so that the strength of the wood structure engineering material can be remarkably improved.
Description
Technical field
The invention belongs to wooden engineering material and make the field, be specifically related to high-intensity wood Structural Engineering material manufacture method.
Background technology
China's artificial forest area, forest stock occupy the first in the world, and the artificial forest wood resource is very abundant.With after small diameter grade artificial forest wood jagsaw sectility branch, drying, planing, the applying glue again assembly gummed preparation Structural Engineering material be to improve the effective way that China artificial tree aptitude source utilizes added value.At present, the adhesive length of penetration is not enough after utilizing artificial forest wood manufacturing wooden structures engineering material to have subdivision sheet material or square bar gluing, sheet material or square bar cemented surface are difficult to form effective glue nail, and the bonding strength of cemented surface is under some influence, and have restricted the development of wooden structures engineering material.
Summary of the invention
The invention reside in provides a kind of wooden structures engineering material processing method with higher mechanical strength.
Technical problem solved by the invention realizes by the following technical solutions:
The wooden Structural Engineering material of a kind of high strength manufacture method, the notable feature that is different from other manufacture methods is: before subdivision sheet material or square bar gluing sheet material or square bar gummed surface are carried out the laser boring processing, at sheet material or the surperficial micropore of getting certain depth, certain diameter of square bar gummed, gluing, assembly cold moudling then, can form effective glue nail at sheet material or square bar glue interface after the moulding, reach the purpose that increases wooden bridge structure engineering material intensity.
Concrete grammar is as follows:
(1) small dimension wood sawing subdivision: adopt band sawing machine that speed is given birth to small dimension wood and be split into certain thickness sheet material or square bar;
(2) remove defective: the burl on sheet material or the square bar, the rotten or part of damaging by worms are blocked removal.
(3) drying: will remove sheet material after the defective and obtain square bar to send into drying kiln for drying be about 10% to moisture content, then balance 1 time-of-week under indoor environment.
(4) planing and spreading: adopt two-sided thicknesser with sheet material or the two-sided planing of square bar, and carry out thick surely processing.The method that adopts finger is with short sheet material or square bar spreading.
(5) laser boring is handled: the sheet material after the two-sided planing or square bar are sent into laser-beam drilling machine laser boring is carried out on sheet material or square bar surface handled.
(6) gluing: sheet material after laser boring handled or square bar are sent into glue spreader and are carried out surface coating.
(7) assembly is colded pressing: will send into cold press cold moudling behind sheet material behind the gluing or the square bar assembly.
In laser boring treatment process of the present invention, laser intensity, charging rate are relevant with sheet material or square bar thickness, and be embodied in: sheet material or square bar thickness are big, and laser intensity is big, and charging rate is slow, and the micropore degree of depth and density are big.
Beneficial effect:Utilize the wooden structures engineering material of method preparation of the present invention, owing to set up the laser boring treatment process, sheet material or square bar Surface Machining the micropore of certain depth, certain density, glue interface can form more effective glue nail, can obviously improve wooden structures engineering material intensity.
