Description
Technical field
The utility model relates to the finger jigsaw is the structure composite plate of sandwich layer, belongs to wood-based plate manufacturing technology and application in the timber industry.
Background technology
Structure material need have very high mechanical property, presentation quality, impact resistance, wear-resisting, anti-worm corruption, fast light photograph and performance such as ageing-resistant because of it.For a long time, structure material mainly is to utilize the timber of high-quality to make, the high-quality timber resources of China is day by day rare at present, how to keep by import, in addition timber also have easy hygroscopicity, strain cracking, damage by worms rotten, natural flaw such as wear no resistance, add that the various defectives (as knot, swirls etc.) in the arboreal growth process cause the inhomogeneous of quality, the plate face width degree of timber also is subjected to the restriction of the age of tree, so timber is restricted as structural timber.Bamboo plywood and thin bamboo strips used for weaving Strength of Plywood height, wearability are good as the platform floor history of existing more than ten years, but the crack that also exists on the bamboo wood expanding sheet is many, have the shortcomings such as tabasheer of influence gummed in the bamboo curtain splint, and raw-material quality and output also are restricted.
The utility model content
The utility model proposes at above-mentioned contradiction just, and providing a kind of is the structure composite plate of sandwich layer with the finger jigsaw.
Technical solution of the present utility model is: a kind of is the structure composite plate of sandwich layer with the finger jigsaw, at the surface layer up and down of finger jigsaw the bamboo material stacked material of one deck is set respectively.
Second kind of technical solution of the present utility model be, a kind of is the structure composite plate of sandwich layer with the finger jigsaw, four layers of dipping weatherability glue respectively is set and through vertical texture bamboo curtain splint of low temperature drying at the surface layer up and down of finger jigsaw.
The third technical solution of the present utility model is, a kind of is the structure composite plate of sandwich layer with the finger jigsaw, surface layer up and down at the finger jigsaw respectively is symmetrical arranged one deck hard paper from outside to inside, one deck dipping phenol glue and through the low temperature drying bamboo mat, three layers of dipping weatherability glue and through vertical texture bamboo curtain splint of low temperature drying.
The 4th kind of technical solution of the present utility model is, a kind of is the structure composite plate of sandwich layer with the finger jigsaw, surface layer up and down at the finger jigsaw respectively is symmetrical arranged one deck hard paper from outside to inside, one deck coating phenol glue and through low temperature drying cross grain Wooden veneer, three layers of dipping weatherability glue and through vertical texture bamboo curtain splint of low temperature drying.
Advantage of the present utility model: with the finger jigsaw be sandwich layer structure with bamboo-wood plyboard as engineering material, compare with timber and to have many advantages, at first bamboo timber resource is abundant, and bamboo resource has once cultivates successfully, get final product the advantage of continuous utilization, the mao bamboon material generally can be cut down utilization in growth after 5 years, and the bamboo that grows thickly of southern area just can be cut down utilization in 2～3 years.Adopt on the structure complete vertical thin bamboo curtain splint arrange high pressure (＞4.5MPa) hot-press gluing forms under the condition, the mechanical property of the bamboo fiber board that makes is higher, concerning thickness is all woolen bamboo bamboo curtain splint laminated timber of 21mm, vertical MOR (MOR) 〉=120MPa, elastic modelling quantity (MOE) 〉=13000MPa, 24 hours thickness swelling rate≤2%, phenomenons such as free from insect pests, cracking, distortion take place, wearability is good, outward appearance is good and smooth, and superior performance is in general hardwood, bamboo plywood and thin bamboo strips used for weaving glued board.As with the Dendrocalamus sinicus of better performances as raw material, its mechanical property can also improve more than 30%.Because adopt the high bamboo curtain splint laminated timber of intensity in the upper and lower surface of plate, sandwich layer adopts the wood finger joint jigsaw, makes composite board not only have higher mechanical property, and the wood-based plate of the full bamboo of weight ratio wants light.Can into the once assembling of bamboo-wood plyboard will be changed to multiple working procedures such as the saw of timber, plane, drying, adjustable cast iron planes.So technology is simple, the plate face is smooth, seamless in addition.As posting with hard paper on the top layer, the sheet material of making need not paint, just can directly use, and is particularly suitable for outdoor application.
