Abstract
The invention discloses a stacking method used in solid wood board drying. The method includes the steps that a log is sawn into boards of various thicknesses, wherein the boards comprise the rough-edge boards and the flat-edge boards, and the thickness of each board is smaller than the width of the board; the solid wood boards are stacked into multiple board stacks in a drying room or an outdoor drying shed, wherein each board stack comprises multiple layers of boards, the boards in each board stack are the same in tree species and thickness, the boards on the lower portions of the board stacks are plain-sawed boards, the boards on the middle portions of the board stacks are semi-plain-sawn boards or radius-sawn boards, the boards on the upper portions of the board stacks are quarter-sawn boards, multiple spacer bars of the same thickness are placed between every two adjacent layers of boards at equal intervals, the spacer bars between the layers are the same in number and corresponding in position, and weights are placed at the tops of the board stacks; tangent lines of annual rings are drawn with the cross sections of the wood boards as reference planes and the intersecting points of the wide-side center lines of the boards and the annual rings as tangent points, wherein the boards with the included angles between the tangent lines and the wide sides of the boards being 0-30 degrees are the plain-sawn boards, the boards with the included angles between the tangent lines and the wide sides of the boards being 30-60 degrees are the semi-pain-sawn boards or radius-saw boards, and the boards with the included angle between the tangent lines and the wide sides of the boards being 60-90 degrees are the quarter-sawn boards.
Description
Technical field
A kind of clamp method when being dried the present invention relates to solid wood board
Background technology
Timber has a drying shrinkage bulking characteristic, and drying shrinkage bulking is not that the gamut in water-cut variation occurs, only when
When the moisture content of timber changes between absolutely dried condition and fibre saturated point state, the drying shrinkage bulking characteristic of timber can just show
Come.Timber in drying process, after moisture content is down to fibre saturated point (usually 30% or so), with moisture content after
Continuous to reduce, gradually dehydration is dried timber, will shrink phenomenon.It is different from other homogeneous materials (such as metal, glass), wood
Material is a kind of anisotropic material, when there is drying shrinkage bulking, there is notable difference, the change of longitudinal direction along the variable quantity of different directions
Change amount is 0.1-0.3%, and the variable quantity of radial direction is 3-6%, and tangential variable quantity is 6-12%, and different directions shrink size and differ
Sample, timber will deform, deflection increase, and when next process is planed, the planing amount of timber will increase, generation
Wood shavings quantity increases, and the volume of timber amount of solid wood is reduced, the utilization rate reduction of timber.In order to reduce the deformation during drying of wood
Amount, so as to reduce allowance, improves the utilization rate of timber, and researcher has done many research work, but on going result is big
Focus mostly in terms of the development of timber dryer, the adjustment of drying process.
The content of the invention
The purpose of the present invention is：Clamp method when a kind of solid wood board is dried is provided, by the dry solid wood of this method
Sheet deformation amount is small, allowance is few, can improve the utilization rate of timber.
The technical scheme is that：A kind of clamp method when solid wood board is dried, it is characterised in that：With following step
Suddenly：The 1st, log saw is made the sheet material of various thickness, including flash plate and treating selvedge plate, the size in sheet metal thickness direction is less than
Width；2nd, in the drying loft for drying indoor or outdoors, solid wood board is piled into several material heaps, each material heap has
Some laminate materials, in same material heap, the seeds of sheet material are identical, sheet material thickness is identical；3rd, the bottom of each material heap is plain-sawed lumber,
The middle part of material heap is half plain-sawed lumber or half quarter-sawed lumber, and the top of material heap is quarter-sawed lumber, and every layer of sheet material is placed with some stripe pitch phases
Deng, thickness identical parting bead, the parting bead quantity of each interlayer is identical, position mutually corresponds to, and weight is placed with the top of material heap.
Described plain-sawed lumber, be the crosspiece face with wood plank as reference plane, with sheet material broadside center line and annual ring line joining
Make the tangent line of the annual ring line, be plain-sawed lumber when the angle of tangent line and sheet material broadside is 0~30 °；Half described plain-sawed lumber or half
Quarter-sawed lumber, be the crosspiece face with wood plank as reference plane, cutting for the annual ring line is made with annual ring line joining with sheet material broadside center line
Line, is half plain-sawed lumber or half quarter-sawed lumber when the angle of tangent line and sheet material broadside is 30~60 °；Described quarter sawing sheet material, be with
The crosspiece face of wood plank is reference plane, and the tangent line of the annual ring line is made with sheet material broadside center line and annual ring line joining, when tangent line with
It is quarter-sawed lumber when the angle of sheet material broadside is 60~90 °.
Described hothouse is to spontaneously dry room, conventional steam hothouse, dehumidification drying kiln, vacuum high-frequency hothouse or micro-
One kind therein of ripple hothouse.
The clamp method when solid wood board that uses is dried in production at present is：For plain-sawed lumber, half plain-sawed lumber or radius
Cutting plate, quarter-sawed lumber, these different types of sheet materials are not that layering is stacked in same material heap, but are put at random, plain-sawed lumber position
The situation for being located at material heap bottom in material heap top or quarter-sawed lumber can often occur, and this disposing way is dried as a result, dry
The big sheet material of dry deflection is more, clamp method of the invention, makes that plain-sawed lumber bears maximum pressure and quarter-sawed lumber bears minimum pressure
Power, can be obviously reduced the difference of Chordwise shrinkage and radial shrinkage rate, efficiently solve that drying of wood deflection is big, cracking phenomena
Many problems, so that planing amount when reducing sheet material following process, compression process surplus, improve the volume recovery of solid wood board, section
About timber resources.

Specific embodiment
A kind of clamp method when solid wood board is dried, after log precessing saw is made as sheet material, still contains more water inside it
Point, the need for meeting transport and being processed further, most of moisture must escape timber, and its moisture content is reduced to technology will
The scope asked, this process is referred to as the drying of wood, and treatment is dried to solid wood board, either spontaneously dries or artificial dry
It is dry, it is required for that sheet material is piled into pile according to certain technical requirements before it is dried, the method and technological requirement of stacking are to drying
Quality and dry the duration and will produce conclusive influence；The inventive method is the plate that log saw is made various thickness
