Abstract
The utility model discloses a wood-based composite board comprising a surface layer, a core layer and a central layer. The technical scheme of the utility model is as follows: the surface layer is a wood-based finger-joint board; the core layer and the central layer are wood-based rotary-cut boards; and the adjacent layers are arranged in a way that the grain directions thereof are perpendicular to each other and are glued with each other. By using the composite structure of the finger-joint board and the rotary-cut boards, the utility model increases the stiffness and flatness of the composite board and reduces the natural warping degree of the composite board, and the product of the utility model has the advantages of high strength, small difference in physical property and mechanical property and good environmental performance.
Description
Art skill field
The utility model relates to a kind of composite wood board with sandwich construction.
Background technology
In the prior art, owing to be subjected to the restriction of original wooden bore, the width of original plank is limited, often will repeatedly splice when making sheet material, and the time, splitting, stitching will appear in splicing place for a long time slightly; Adopt wood-based plate then because generally thinner, its intensity is unsatisfactory, can not satisfy to make relatively large or the family property of mechanics requirement, the requirement of finishing are arranged.
Summary of the invention
The purpose of this utility model is at above shortcomings in the prior art, a kind of intensity height is provided, be not limited to original wood size, splicing less and the composite wood board of environmental protection.
For solving the problems of the technologies described above, the utility model composite wood board comprises top layer, sandwich layer and central core, and its technical scheme is: described top layer is wooden finger plate, and described sandwich layer and central core are wooden rotary-cut plate; The vertical in length and breadth each other and gummed of the grain direction of adjacent layer.
Because sandwich layer of the present utility model and central core are monoblock rotary-cut plate, there is not splicing, reduced the use of adhesive thereby conservation, environmental protection, the plate of rotary-cut simultaneously also has the physical property of flatness height, good thermoplastic; The finger joint grafting wedging of outer finger wood can effectively utilize undersized log, saves original wood; The combining structure of finger plate and rotary-cut plate has strengthened stiffness, the flatness of composite board, reduces the nature angularity, makes this product strength height, and its physics, mechanical performance difference are little, good environmental protection.
Description of drawings
Fig. 1 is the structural representation of the utility model composite wood board;
Mark among the figure: 1-top layer, 2-sandwich layer, 3-central core.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
The specific embodiment
As shown in Figure 1, the utility model composite wood board comprises top layer 1, sandwich layer 2 and central core 3, and its technical scheme is: described top layer 1 is wooden finger plate, and described sandwich layer 2 and central core 3 are wooden rotary-cut plate; The vertical in length and breadth each other and gummed of the grain direction of adjacent layer.
Described sandwich layer can be two layers, and balanced configuration is at the upper and lower surface of central core respectively for two layers of sandwich layer, and the grain direction of adjacent layer is vertical in length and breadth each other also to be glued together, and at this moment, composite wood board is five layers of composite wood board, referring to Fig. 1.
Described sandwich layer can be four layers, and balanced configuration is in the top and bottom of central core respectively for four layers of sandwich layer, and the grain direction of adjacent layer is vertical in length and breadth each other also to be glued together, and at this moment, composite wood board is seven layers of composite wood board.
As improvement of the present utility model, described sandwich layer is an even level, and balanced configuration is in the top and bottom of central core respectively for the sandwich layer of even number, and the grain direction of adjacent layer is vertical in length and breadth each other also to be glued together.
Claims (4)
