Description

A kind of preparation method of hollow solid wood pin
Technical field
The present invention relates to a kind of timber processing method, particularly a kind of preparation method of hollow solid wood pin.
Background technology
For larger specification, the perfectly straight round log post of texture, when especially requiring to use high-quality timber, this mode of log of directly utilizing has become more and more difficult, and material is difficult to obtain, and price is higher.The log of large specification, because the control of moisture content and the safeguard procedures difficult treatment such as anticorrosion, without rational preliminary treatment, the material that directly uses, the product military service is of poor quality, such as phenomenons such as cracking, distortion, warpages.Use at humid areas outdoor or that the entomogenous fungi disaster is serious such as fruit product, be subject to entomogenous fungi and corrode and rotten rotten degradation, the service property (quality) of product, security, outward appearance and service life reduce greatly.Simultaneously, the material of large specification often inevitably occur local rotten, die for the sake of honour, the serious defectives that reduce material mechanical performance such as cavity, twill, bring potential safety hazard to the use of member.Common log pin is solid construction, up to now, does not still take out the reasonable means of heart section by processing modes such as machineries, to make hollow-core construction.Therefore in decorations, the auxiliary material such as water pipe, electric wire, cable can only be arranged in the outside, need to adopt extra mode to be blocked, and decorative effect is poor.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of preparation method of hollow solid wood pin.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of preparation method of hollow solid wood pin is provided, and the step of described processing method comprises:
The first, analyze the blank size of member data and calculative determination wood cell, log is cut into the timber unit of required size;
The second, strengthen the timber unit, make the timber unit obtain predetermined service behaviour;
The 3rd, prepare hollow solid wood pin, the timber unit after strengthening is carried out size fine finishining, then process finger-type tooth or Tenon in its side, stick with glue agent at connection teeth or to be bonded applying structure of Tenon, structure sticks with glue the coating weight of agent at 150-400g/m 2In the scope, then exerted pressure with the orthogonal direction of its thickness in the timber unit that contains finger-type tooth or Tenon, pressure is controlled at the 1.0-4.0MPa scope, the operation of all glue laminateds is all finished in the scope of temperature more than 18 ℃, relative humidity 50-85%, after adhesive fully solidifies, again with its maintenance at least 2 days in this environment, to make hollow solid wood pin;
The 4th, to hollow solid wood pin carry out outer surface scrape or polish, mend putty, repairing and etc. modify and process, make the pin product, check at last, number, pack warehouse-in.
Preferably, the manufacturing process of described second step timber unit comprises:
A, dry timber unit adopt the method for controlling water content of soft benchmark, make the moisture content of timber unit be down to 25%;
B, timber unit modification, semi-finished product timber unit is immersed in the modifier solution of reinforced resins configuration, ancillary method can roll for normal temperature and pressure, cold and hot groove, roller the modes such as contracting or vacuum pressed, or is aided with simultaneously the mode of ultrasonic equipment concussion;
The dehydration of timber unit under the environmental condition that is lower than 40 ℃ of temperature, is down to below 25% its moisture content after c, the modification;
D, the semi-finished product timber unit after the modification is placed 105 ℃-140 ℃ hot pressing temperature, the hot pressing pressure of 0MPa-0.5MPa in the flexible thermal press of the hot pressing speed of 2min/mm-5min/mm, carries out the shaping process of timber internal resin under the effect of temperature.
The invention has the beneficial effects as follows: the preparation method that a kind of hollow solid wood pin is provided, bearer types and characteristics according to finished product, at first calculate the size of pin product wood cell, and then directly produce the timber unit of correspondingly-sized on the log, the timber unit then obtains its service behaviour by the method that modifier solution soaks, the most at last unit timber splicing glue molding.The Rigidity and strength isostructuralism of this product can have designability, and its preparation section is simple, and the preparation expense is low, and financial gain is high.
