Parallel and vertical with face ply machine direction, multiple-plate total number of plies is even number and >=4, surface layer (1), backing layer (2), core
The lumber fibre direction of the face ply of layer is consistent with floor length direction.
One preferred embodiment of the utility model is the multi-layer solid wood composite floor of a type three-decker, it
Construction include surface layer (1) and backing layer (2), sandwich layer (3) are provided between surface layer (1) and backing layer (2), sandwich layer (3) internal layer
Respectively there be 1 layer of face ply in veneer two sides, are that face ply is vertical with adjacent inner layer veneer machine direction and adjacent inner layer veneer is fine
Tie up the parallel multi-layer board in direction, which is even number and >=4, surface layer (1), backing layer (2), sandwich layer face ply
Lumber fibre direction it is consistent with floor length direction.
One preferred embodiment of the utility model is the multi-layer solid wood composite floor of a type three-decker, it
Construction include surface layer (1) and backing layer (2), sandwich layer (3) are provided between surface layer (1) and backing layer (2), sandwich layer (3) internal layer
Respectively there are 2 layers of face ply in veneer two sides, the face ply parallel with time face ply machine direction, secondary that is face ply with it is adjacent interior
Layer veneer machine direction be vertical and multi-layer board that adjacent inner layer veneer machine direction is parallel, which is even number
And >=6, surface layer (1), backing layer (2), sandwich layer face ply lumber fibre direction it is consistent with floor length direction.
Preferably, total number of plies of internal layer veneer is 4 layers or more in the sandwich layer (3).
In the solid wooden compound floor, the sliced veneer or wood skin of the precious high-quality hardwood of surface layer use, multiselect teak,
Walnut, maple, Manchurian ash, birch, beech, oak (toothed oak wood), beech, Chinese catalpa wood, cherry etc., have solid wooden compound floor
For the native texture and surface hardness of solid wooden floor board.Backing layer is usually cork rotary cut venner, and tree species are usually poplar, pine
Deng.In the solid wooden compound floor, sandwich layer generallys use the rotary cut venner of Eucalyptus or poplar, by internal layer veneer and face ply
The multi-layer board of a type three-decker is formed through sizing, assembly, cold pressing, hot pressing.
In the solid wooden compound floor, surface layer, backing layer and sandwich layer are formed through sizing, assembly, cold pressing, hot pressing.
The utility model has the advantages that
1) multi-layer solid wood composite floor of class three-decker of the invention, center adjacent layer lumber fibre direction is consistent, in
Intracardiac layer bonding strength enhancing, overcomes custom plywood (the criss-cross assembly of adjacent layer) to do the prior art defect of sandwich layer.
2) multi-layer solid wood composite floor of class three-decker of the invention, sandwich layer using class three-decker multi-layer board, same
When on the whole still use three-layer wood composite flooring structure, but the sandwich layer of solid wooden compound floor of the invention using fast growing wood,
The rotary cut venner of the timber such as small dimension wood and then raising timber utilization rate, while each layer veneer through glue molding and then improves sandwich layer
Resistance to wet stability.
3) multi-layer solid wood composite floor of class three-decker of the invention uses total number of plies for the full symmetric knot of even number
Structure is effectively reduced in timber compared to the odd-level structure of traditional three-layer wood composite flooring and multi-layer solid wood composite floor
Stress avoids floor buckling deformation.
