Abstract
This utility model discloses a kind of OSB bearing plate, including intermediate core layer, it is symmetricly set on upper epidermis and the layer of intermediate core layer both sides, described intermediate core layer is in laterally to mat formation to form by multilamellar wood chip, described upper epidermis, layer are to be formed in longitudinally mating formation by multilamellar wood chip, are bonded by formaldehydeless glue between described intermediate core layer, upper epidermis, layer.Using described OSB bearing plate, thereon, layer multilamellar wood chip is longitudinally mated formation laterally to mat formation to interlock with intermediate core layer and is formed, it is bonded by formaldehydeless glue between each layer, form that a kind of structural strength is high, the coefficient of expansion is little, the strong feature of nail-holding ability, especially, wet applications environment, the service life that waterproof layer is improved whole sheet material can be arranged on upper epidermis, especially, there is aesthetic, decorative layer can be arranged on upper epidermis.It can be widely applied to interior decoration, building construction, packaging material and Furniture manufacture, has good Social benefit and economic benefit.
Description
Technical field
This utility model is related to OSB plate field and in particular to a kind of OSB bearing plate.
Background technology
OSB plate, also known as oriented wood chipboard, also name Europe deals, is a kind of synthesized wood material, its sheet material with small dimension wood, thinnings,
Reel is raw material, is grown up long flaking by professional equipment processing, through drying, screening, gluing, mat formation, hot pressing, cooling, sanction
A kind of directional structure board that the techniques such as side are made.
Because OSB intralaminar part is directive construction, non junction, seamless, slight crack, overall uniformity are good, internal bond strength
High, so central authorities or edge all have common sheet material, and incomparable superpower holds nail ability.
, compared to plate kinds such as plywood, medium density fibre board (MDF) and thin planks, its linear expansion coefficient is little for OSB plate, stable
Property good, uniform in material, supine human body is higher, and because its wood shavings arranges in certain direction, its longitudinal bending strength is than horizontal
To much bigger, therefore can do structural material, and be used as primary structure member.
But because wood shavings differ in size, the wood shavings direction of pavement process and angle are it cannot be guaranteed that fully level and all
Even, certain density gradient can be formed, poor on thickness evenness and stability.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of OSB bearing plate.
This utility model is that the adopted technical scheme that solves the above problems is：There is provided a kind of OSB bearing plate, including middle
Sandwich layer, is symmetricly set on upper epidermis and the layer of intermediate core layer both sides, and described intermediate core layer is in laterally to mat formation by multilamellar wood chip
Form, described upper epidermis, layer are to be in longitudinally to mat formation to form by multilamellar wood chip, described intermediate core layer, upper epidermis, layer it
Between be bonded by formaldehydeless glue.
Intermediate core layer is formed with reel for Raw material processing, and it is laterally to mat formation to form, and longitudinally mats formation with upper and lower top layer and is formed
It is staggered, wood grain of having recombinated structure, eliminate the impaired defect of frangibility that its internal stress causes, upper and lower top layer wood
Piece longitudinal arrangement, each sublayer interval ordered arrangement of its composition, middle sandwich layer is transversely arranged to mat formation, and it is each that it forms
Individual sub- interlayer every ordered arrangement, after formaldehydeless glue bonds, can between upper epidermis, intermediate core layer and layer mutually
Staggered orderly be fixed together it is ensured that the internal non junction of whole OSB bearing plate, and whole boarding thickness is uniformly, lifting
The stability problem that when it uses, uneven thickness is brought.
Further, described upper epidermis is additionally provided with waterproof layer laterally, under general wet environment, by arranging in upper epidermis
Waterproof layer can extend the service life of whole OSB bearing plate.
Further, described upper epidermis is additionally provided with decorative layer laterally, in order to reach the demand of certain applications aspect, passes through
Put decorative layer in upper table furnishings, the aesthetics of total can be lifted, there is certain dicoration.
Further, described formaldehydeless glue is isocyanate adhesive, abbreviation PMDI glue.
Further, described multilamellar wood chip is by one or more of poplar, Masson Pine, Lignum seu Ramulus Cunninghamiae Lanceolatae, because this timber is non-big
The quality material of footpath level, common small dimension wood can be used as raw materials for production, reduces production cost.
Further, described OSB load-bearing plate thickness is 9mm-18mm.
Further, described OSB load-bearing plate thickness is 12mm or 15mm.
What OSB bearing plate described in the utility model brought has the beneficial effect that：Using OSB load-bearing described in the utility model
Plate, thereon, layer multilamellar wood chip longitudinally mat formation with intermediate core layer laterally mat formation staggered form, pass through formaldehydeless glue between each layer
Water is bonded, and a kind of structural strength of formation is high, the coefficient of expansion is little, the strong feature of nail-holding ability, especially, some wet applications rings
Border, can arrange the service life that waterproof layer is improved whole sheet material on upper epidermis, especially, compare in some aesthetic
In the case of height, decorative layer can be arranged on upper epidermis for improving the aesthetics of whole plate construction.It can be widely applied to
Interior decoration, building construction, packaging material and Furniture manufacture, have good Social benefit and economic benefit.
Brief description
Fig. 1 is the structural representation of this utility model embodiment 1；
Fig. 2 is the structural representation of this utility model embodiment 2；
Fig. 3 is the structural representation of this utility model embodiment 3；
Specific embodiment
Below in conjunction with concrete accompanying drawing, this utility model is further described.
Embodiment 1
As shown in figure 1, providing a kind of OSB bearing plate, including intermediate core layer 2, it is symmetricly set on the upper of intermediate core layer 2 both sides
Top layer 1 and layer 3, intermediate core layer 2 is in laterally to mat formation to form by multilamellar wood chip, and upper epidermis 1, layer 3 are by multilamellar wood chip
Form in longitudinally mating formation, be bonded by isocyanate adhesive between upper epidermis 1, intermediate core layer 2, layer 3, three-decker group
The OSB bearing plate gross thickness becoming is 9mm, 12mm, 15mm and 18mm tetra- type.
This structure OSB bearing plate is mainly used in building construction, interior decoration etc. to be needed to support the situation of certain bearing capacity, respectively
Layer is bonded afterwards so that total has very high bending strength by isocyanate adhesive, can bear certain gravity.
