Description
Technical field
The present invention relates to wood processing technique field, especially a kind of processing technology of integrated timber.
Background technology
At present, countries in the world are in sustainable growth situation to the demand of timber, and particularly people are to natural wood products
Pursuit will be more urgent, but the undersized log that the continuous reduction and artificial fast-growing woods in face of natural big-diameter wood resource provide increasingly increases
It is more, increasing country's limitation or the outlet for forbidding log and preliminary working product, thus the reality using inferior material as raw material
Wooden integrated timber turns into the ideal material of interior decoration and medium-to-high grade Furniture manufacturing, structural glulam can be used as gymnasium, factory building,
The timber structure beam of the buildings such as warehouse, log cabin, it is widely used in Europe and north America region.But traditional processing technology produces
Integrated timber toughness, bond strength intensity, the resistance to compression tensile property gone out is all poor.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of processing technology of integrated timber so that the integrated timber produced
With physical properties such as stronger toughness, bond strength and resistance to compression tensions.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：
A kind of processing technology of integrated timber, comprises the following steps：
A. tooth punching：Several teeth are opened in each batten termination, and the tooth depth of each tooth is 4mm；
B. spreading：The termination of two battens is bonded using extrusion；
C. splice：Some battens to be formed at faying face by adhesive successively cold be stitched together using cold spelling machine
Sheet material.
Further, 8 tons of hydraulic jacks are used in the step B.
Further, cold spelling is completed in 60 minutes using 12MPa operating pressure continuous action in step C.
Further, before the step A, first timber to be placed on and dries in cellar for storing things to enter using high temperature and circulated air
Row drying.
Further, before the step C, the faying face of the batten scrape sanding flat.
Further, the sheet material plate face scrape sanding flat after the step C.
A kind of processing technology of integrated timber of the present invention so that the integrated timber produced has stronger toughness, bond strength
With the physical property such as resistance to compression tension.
Embodiment
A kind of timber such as processing technology of integrated timber, raw material arrow-leaved oleaster wood used in the present invention, elm, willow belongs to broad-leaved
Hard weedtree, be it is non-use ability seeds, conventional peasant household is used to making a fire, barbecue uses, and does not produce economic value, because this project process it is real
Wooden integrated timber need to largely use such timber, improve the enthusiasm of peasant household kind tree, add the income of peasant household.
The present invention comprises the following steps：
A. tooth punching：25 teeth are opened in each batten termination, and the quantity of specific tooth can be adjusted 24 or 26 according to actual conditions
Individual etc., the tooth depth of each tooth is 4mm.
B. spreading：The termination of two battens is bonded using extrusion；
C. splice：Some battens to be formed at faying face by adhesive successively cold be stitched together using the cold spelling machine of side pressure
Sheet material.
8 tons of hydraulic jacks are used in step B.
Cold spelling is completed in 60 minutes using 12MPa operating pressure continuous action in step C.
Before step A, first timber to be neatly placed on and dry in cellar for storing things and leave gap between timber, utilize high temperature
It is dried with circulated air.Dry kiln is surface structures, and long 8 meters, wide 4 meters, high 4 meters, assembling is at the top of dry kiln
Centre position, every 3 hours automatic conversion wind directions, because of the density and moisture content of timber, makes specific drying time, makes
Timber reaches uniform drying.
Before step C, the faying face of batten scrape sanding flat.
Sheet material plate face scrape sanding flat after step C.
In step A, relative to traditional tooth punching 10mm tooth depths, the area of batten termination faying face is effectively increased, when adopting
Be long 2.44m with batten specification, the long 0.0583m in batten termination, batten thickness 0.015m when, batten termination combines in the present embodiment
3 times of cross-sectional area when the area in face is the non-tooth punching in batten termination.Specifically it is calculated as follows：During the non-tooth punching in batten termination
Cross-sectional area：The ㎡ tooth one side areas of 0.0583m × 0.015m=0.0008745 are：0.015m×0.004m=0.00006 ㎡
The gross area of 25 teeth is：The ㎡ of 0.00006 ㎡ × 2 × 25=0.003 then, the gross area of tooth punching termination and non-tooth punching end
The ratio of the area of head is 0.0008745=3.44828 times of 0.003 ÷.
Improved in terms of faying face increase, the physics characteristic such as bond strength enhancing, pliability, compression and tensile strength
1.5 again.
Cold spelling is used in step C, under certain pressure long duration of action, glue slow curing, infiltration are deep, are combined in timber
Face forms hole for nailing, adds bond strength.By being sand flat before step C to scraping for batten faying face, effectively reduce viscous
The usage amount of mixture, and ensure that burst size of methanal is less than international standard.In the present embodiment, 24 battens integrate sheet material bonding
Agent dosage is every square metre of 0.03316 gram of sheet material, only the 1/5 of conventional method.
A kind of processing technology of integrated timber of the present invention so that the integrated timber produced has stronger toughness, bond strength
With the physical property such as resistance to compression tension.
