Abstract

The utility model discloses a composite bamboo plywood which is manufactured by a drying method and contains organic adhesive and bamboo fibers. The composite bamboo plywood is a whole consisting of a plurality of bamboo veneers (1) overlapped by same double-layer bamboo single sheets connected through female connectors and male connectors; the female connector on the bamboo veneer (1) is groove-shaped; the width of the mouth of the groove is smaller than that of the bottom of the groove; correspondingly, the male connector on the bamboo veneer (1) is raised head-shaped; and the width of the top of the raised head is more than that of the bottom of the raised head. By changing the shape of the connector, the bamboo veneers (1) can be connected only through the buckling method, the movement of the bamboo veneers (1) on a board is limited by utilizing the own structural characteristics of the bamboo veneers (1) without the organic adhesive, after the hot-press gluing of the bamboo veneers (1) through the organic adhesive, the bonding strength of the board of the composite bamboo plywood is improved, and the overall performance of the composite bamboo plywood is also improved.

Description

The combined type bamboo plywood

Technical field

The utility model relate to a kind of with the drying means manufacturing, have the machine binder, contain the article of wood fibre, particularly relate to a kind of combined type bamboo plywood made from bamboo material.

Background technology

Bamboo plywood is widely used in building, household field, existing bamboo plywood manufacture method mainly is that first bamboo rotary cutting with certain-length becomes certain thickness bamboo monolithic, then several bamboo monolithics are superposeed on thickness direction and synthesize the bamboo veneer, the synthetic glued board of at last several bamboo veneers being pegged graft on the plate face mutually with required specification.The performance of the bamboo plywood of this method manufacturing depends primarily on the quality of organic bond quality, irrelevant with the version of bamboo monolithic or bamboo veneer, this connected mode of particularly pegging graft is helpless to improve the bond strength on the plate face, in case As time goes on the performance of organic bond weakens or lost efficacy, bamboo plywood can not use.

The utility model content

The technical problems to be solved in the utility model is a kind of by changing interface shape and method of attachment, reaching the combined type bamboo plywood that improves plate face bond strength.

For solving the problems of the technologies described above, a kind of combined type bamboo plywood of the utility model, be both the bamboo veneer that multilayer bamboo monolithic is formed by stacking by many and interconnect an integral body that forms by cloudy interface and positive interface, its cloudy interface is shaped as groove, and the width of rebate size of groove is less than the bottom land size of groove; Corresponding therewith, positive interface is shaped as plush copper, and the top width size of plush copper is greater than the bottom size of plush copper.

Described a kind of combined type bamboo plywood, being shaped as of its cloudy interface and positive interface is trapezoidal.

Described a kind of combined type bamboo plywood, its cloudy interface and positive interface be shaped as right-angled trapezium.

Described a kind of combined type bamboo plywood, its cloudy interface and positive interface be shaped as swallow-tail form.

Described a kind of combined type bamboo plywood, its cloudy interface and positive interface be shaped as the T font.

Described a kind of combined type bamboo plywood, its cloudy interface and positive interface be shaped as the L font.

Described a kind of combined type bamboo plywood, its cloudy interface and positive interface be shaped as wedge shape.

Described any combined type bamboo plywood, its bamboo veneer is formed by stacking by 2～6 layers of bamboo monolithic.

Described any combined type bamboo plywood, the thickness of its bamboo veneer is 1～5mm.

Because the utility model is by changing the shape of interface, the bamboo veneer can only be connected by the snapping mode, no organic bond situation under, can utilize the design feature of self to reach restriction bamboo veneer moving on the plate face, and the bamboo veneer is by after the hot-press gluing of organic bond, plate face bond strength that not only can single raising combined type bamboo plywood also can improve the overall performance of combined type bamboo plywood.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

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

Fig. 2 is the structural representation of cloudy interface on the utility model bamboo veneer;

Fig. 3 is the structural representation of the utility model bamboo veneer Shangyang interface.

Identify among the figure: 1-bamboo veneer, the cloudy interface of 2-, 3-sun interface.

The specific embodiment

It is the bamboo monolithic of 1mm that the utility model at first becomes thickness with the bamboo rotary cutting of certain-length, and with organic bond 3 bamboo monolithics stack hot-press gluings being become thickness is the bamboo veneer 1 of 3.2mm; According to connection request, as shown in Figure 2, the cloudy interface 2 on the bamboo veneer 1 is processed into the trapezoidal groove of width of rebate size less than the bottom land size; As shown in Figure 3, the positive interface 3 on the bamboo veneer 1 is processed into the trapezoidal plush copper of top width size greater than bottom size; As shown in Figure 1, the positive interface 3 on the bamboo veneer 1 is snapped onto in the cloudy interface 2 on another bamboo veneer 1; Last again by hot-press gluing with organic bond, obtain the combined type bamboo plywood of required specification.

Certainly, the utility model is not limited to above embodiment, and what the shape of cloudy interface 2 and positive interface 3 can be in right-angled trapezium, swallow-tail form, T font, L font or the wedge shape is any; According to required specification, bamboo veneer 1 can be from length direction, width connects; Under the top width size of cloudy interface 2 and positive interface 3 and situation that bottom size is more or less the same, cloudy interface 2 and positive interface 3 also can utilize the flexibility of bamboo wood, adopt this connected mode of pegging graft.
