Abstract

The utility model discloses a bamboo wood plywood of a container. The bamboo wood plywood comprises a bottom layer, a surface layer, an upper layer, a middle layer and a lower layer, wherein the bottom layer and the surface layer are made of crosswise wood veneers, the upper layer and the middle layer are lengthways veneers and long bamboo curtains or short bamboo curtains, and the lengthways veneers and the long bamboo curtains or the short bamboo curtain are glued at intervals, and the lower layer are formed by the lengthways veneers and the long bamboo curtains, and the lengthways veneers and the long bamboo curtains are glued at intervals. The bamboo wood plywood is unsymmetrical in structure. Bamboos and woods are assembled at intervals. The bamboo curtains and the veneers are arranged vertically and horizontally and capable of respectively bearing lengthways intensity and transverse strength, and lengthways static bending intensity and elasticity modulus are improved. Meanwhile, the bamboo wood plywood of the container is capable of increasing use ratios of the veneers and reducing cost. Bamboo curtains are not glued, and bonding performances are improved, and edge holes of panels are reduced. In addition, after the assembly is finished, under the conditions of 135-145 DEG C and unit pressure of 3.0-3.5 Mpa, the density of the manufactured bamboo wood plywood is 0.8-0.9g/cm^3, and the bamboo wood plywood of the container has the advantages of being high in intensity, acid-resisting, alkali-resisting, abrasion-resistant and good in water-proof function.

Description

The container bamboo-wood plywood

Technical field

The utility model relates to a kind of bamboo-wood plywood, relates in particular to a kind of bamboo-wood plywood as container bottom board.

Background technology

Container bottom board is existing nearly 30 years history so far, base plate layer centered by one deck bamboo or one deck wood that traditional bamboo wood composite container is used, upper and lower symmetrical configuration, bamboo curtain splint and veneer are crisscross compound, bear vertical transverse strength respectively, as the applicant's patent CN200960685Y.But there is following problem in this bamboo-wood plywood: 1, vertically MOR and modulus of elasticity are on the low side, do not reach requirement; 2, the gummed that has bamboo curtain splint and bamboo curtain splint is prone to the bad phenomenon of gummed, and hot pressing pressure height, mechanical disorder take place frequently.

The utility model content

The utility model purpose: the purpose of this utility model provides the container bamboo-wood plywood that a kind of vertical MOR is strong, elastic modelling quantity is high.

Technical scheme: container bamboo-wood plywood described in the utility model comprises bottom, surface layer, upper strata, middle level, lower floor; Its bottom and surface layer are horizontal veneer, can be provided with finishing paper in the above; Upper strata and middle level are that vertical veneer glues together at interval with long bamboo curtain splint or short bamboo curtain splint; Lower floor is that vertical veneer glues together at interval with long bamboo curtain splint.

Described long bamboo curtain splint is that some parallel long bamboo bars are tied up composition with the cord transverse tie, and short bamboo curtain splint is that some parallel short bamboo bars are tied up composition with the cord transverse tie, so long bamboo curtain splint is vertical bamboo curtain splint, short bamboo curtain splint is horizontal bamboo curtain splint.

Total number of plies of described bamboo-wood plywood can depend on the circumstances, though this assembly structure is asymmetric, uses the continous way machining process, by reasonable material collocation, can make sheet material very smooth.

Beneficial effect: the utility model compared with prior art, its distinguishing feature is that this bamboo-wood plywood structure is asymmetric, bamboo wood is assembly at interval, bamboo curtain splint, veneer are crisscross, bear respectively vertically, transverse strength, have improved vertical MOR and elastic modelling quantity; Structure has increased the usage ratio of veneer simultaneously, has reduced cost; Do not have bamboo curtain splint and bamboo curtain splint gummed, glue performance is improved, and the sheet edge hole reduces; In addition, be under the condition of 3.0-3.5Mpa at 135-145 ℃, unit pressure behind the assembly, the bamboo-wood plywood density of making is 0.8-0.9g/cm ³, have high strength, acidproof, alkaline-resisting, wear-resisting and advantage that water-proof function is good.

Description of drawings

Fig. 1 is the structural representation of 23 layers of bamboo-wood plywood of the utility model;

Fig. 2 is the structural representation of 21 layers of bamboo-wood plywood of the utility model.

The specific embodiment

As shown in Figure 1,23 layers of bamboo-wood plywood comprise bottom, surface layer, the upper, middle and lower; Wherein, bottom and surface layer are horizontal veneer 3, and upper strata and middle level are that vertical veneer 4 glues together at interval with long bamboo curtain splint 1 or weak point bamboo curtain splint 2, and totally 13 layers, lower floor is that vertical veneer 4 glues together at interval with long bamboo curtain splint 1, totally 8 layers, simultaneously, is provided with finishing paper 5 at bottom and surface layer.

As shown in Figure 2,21 layers of bamboo-wood plywood comprise bottom, surface layer, upper strata, middle level, lower floor; Wherein, bottom and surface layer are horizontal veneer 3, and upper strata and middle level are that vertical veneer 4 glues together at interval with long bamboo curtain splint 1 or weak point bamboo curtain splint 2, and totally 13 layers, lower floor is that vertical veneer 4 glues together at interval with long bamboo curtain splint 1, totally 6 layers, simultaneously, is provided with finishing paper 5 at bottom and surface layer.

Claims

1. a container bamboo-wood plywood comprises bottom, surface layer, upper strata, middle level, lower floor; It is characterized in that: described bottom and surface layer are horizontal veneer (3), and upper strata and middle level are that vertical veneer (4) glues together at interval with long bamboo curtain splint (1) or weak point bamboo curtain splint (2), and lower floor is that vertical veneer (4) glues together at interval with long bamboo curtain splint (1).
