Abstract

The utility model discloses a bamboo-wood composite board, which comprises a bamboo base board and wood thin boards which are covered on the two surfaces of the bamboo base board. The utility model is characterized in that the fiber board are split by single boards. The utility model can make full use of small-diameter wood or leftover materials, so manufacture cost is reduced. The bamboo-wood composite board with the structure has low requirements on wood. The bamboo-wood composite board can be made of rotary cutting boards, and can also be made of horizontal cutting boards.

Description

Bamboo-wood plyboard

The utility model relates to a kind of construction formwork, specifically a kind of bamboo-wood plyboard.

The finish of building for the demolding performace that improves construction formwork and after improving the demoulding, generally adopt multilayer composite sheet at present both at home and abroad, film-covered bamboo fiber board for building shuttering as the record of Chinese invention patent 92107832.3 ublic specification of application, it adopts bamboo matter substrate, the paper that handled coated with wooden thin plate and impregnation on the two sides.But this constructed products adopts the monoblock plank of large format, and stock utilization is low, thereby cost is higher.In fairly large construction, need the polylith composite plate is joined end to end, like this, for guaranteeing construction quality, thickness requirement to every composite plate is very high, and for reaching the precision of regulation, it is adding man-hour earlier with the fixed thick sanding of bamboo matter substrate, be covered with a rotary cut venner and bond paper then on two surfaces respectively, behind thermocompression forming, saw limit, edge sealing.Therefore its another shortcoming is the requirement height to wooden thin plate, and the processing technology complexity.

The purpose of this utility model is to provide a kind of cost lower but bamboo-wood plyboard that strength and stiffness are bigger.

The purpose of this utility model is achieved in that bamboo-wood plyboard, comprises bamboo matter substrate, and bamboo matter substrate two surfaces are covered with wooden thin plate, it is characterized in that described wooden thin plate is formed by veneer splicing.

As further improvement of the utility model, described wooden thin plate is spliced by the strip veneer is vertical or horizontal.

As further improvement of the utility model, described wooden thin plate is laminated with by multilayer and forms.

As further improvement of the utility model, the external surface of described wooden thin plate also is covered with bond paper.

The bamboo-wood plyboard that wooden thin plate adopts veneer splicing to form can make full use of small dimension wood timber or leftover pieces, has reduced manufacturing cost.The bamboo-wood plyboard of this structure, also low to wooden requirement, both can adopt the rotary-cut plate, also can adopt the truncation plate.

Adopt the bamboo-wood plyboard of MULTILAYER COMPOSITE, whole plate thickness can be precisely controlled, therefore can adopt better simply technology.

The external surface of described wooden thin plate is covered with bond paper can increase wearing coefficient, improves finish, and attractive in appearance and rich variation makes it can not only be used as construction formwork, can also be used as decorative panel and engineering veneer.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the another kind of structural representation of wooden thin plate.

With reference to Fig. 1, bamboo matter substrate two surfaces of bamboo-wood plyboard are covered with wooden thin plate, and wooden thin plate is formed by the strip veneer splicing.Wherein, bamboo matter substrate can be the bamboo weaving of bamboo chip, the thin bamboo strips used for weaving braiding with 0.5～5mm, or with bamboo curtain splint, the bamboo mat of line, plastics or thin wire lace one-tenth, the number of plies can for three layers to tens layers.Veneer is strip, forms by longitudinal spliced, or by horizontally-spliced forming (as shown in Figure 2).Plank can be an individual layer, also can be multilayer.The stitching direction of its adjacent two layers veneer of wooden thin plate of MULTILAYER COMPOSITE can be identical, also can be orthogonal.Can also be covered with 1 at the external surface of wooden thin plate to the multilayer bond paper.

The manufacturing process of above-mentioned bamboo-wood plyboard is such: will be dried to one or more layers crossover in length and breadth of wooden thin plate of certain moisture content, and be coated with phenolic resins on the crossover face, and form backing; With the bamboo curtain splint multilayer that is dried to certain moisture content in length and breadth the crossover assembly on backing, the adjacent surface brushing phenolic resins of bamboo chip; Become plane materiel with forming on the bamboo chip that the equal material of backing overlays on the superiors then.

After base material ageing a few hours that said method is made, sending into hot press, is 130～145 ℃ in temperature, and pressure is 15～35kg/cm ², carry out hot pressing by every millimeter 1～2 fen clock time of base material thickness.After hot-forming, saw unhairing limit, two-sided sanding to the thickness of setting promptly becomes bamboo-wood plyboard.Coated with 1～3 bond paper, heating is pressed into the overlay film bamboo-wood plyboard on the surface.Press obedient ornament materials to be the decoration veneer.
