Abstract

The utility model provides a bamboo plywood boxboard relating to a high-strength boxboard, of which the structure strength is higher so that instantaneous large-load pressure can be borne. The bamboo plywood boxboard is formed by stacking and gluing bamboo veneers and wooden veneers with longitudinal texture and transverse texture; the boxboard comprises a bamboo veneer serving as a top plate, a bamboo veneer serving as a soleplate, at least three longitudinal veneer set layers and two transverse veneer set layers, and the transverse veneer set layers are arranged among the longitudinal veneer set layers; and longitudinal wooden veneers are respectively arranged on the outmost layers of the longitudinal veneer set layers on the top and the bottom. According to the utility model, veneers with the same texture direction are 'gathered in groups' and then veneers with different texture directions are crisscross gathered to form a blank. An overall effect is formed among the veneer layers in the same direction, to realize the 'unable to break' effect like chopsticks; then, plural groups of transverse and longitudinal layers 'in groups' are gathered crisscross to form the blank, so that the anti-bending strength and the elasticity of the finished products in the longitudinal direction are greatly increased, simultaneously, the transverse modulus of elasticity is also increased. The bamboo plywood boxboard has a novel concept, and the overall strength is obviously increased under the same material consumption.

Description

Bamboo wood glue mould assembling plate

Technical field

The utility model relates to a kind of high strength boxboard, relates in particular to the base plate of load-bearing occasions such as container, aircraft, train, automobile.

Background technology

Along with the minimizing of high-grade hardwood resource, wood substituted by bamboo can play the effect that protects forest resources.Rise the nineties, and along with the progress of technology, wood substituted by bamboo becomes a kind of trend, is introduced into market gradually.In some load-bearing occasions,, the intensity of sheet material had very high requirement such as the floor/boxboard of container, aircraft, train, automobile.Adopted expensive high-grade hardwood to make mostly, in the period of nearest 5-6, domestic many producers begin to attempt adopting bamboo-wood plywood to make the floor/boxboard of aforementioned load-bearing, have played the effect that reduces cost, alleviates rare hardwood resource in the past.But customers' responsiveness is in use arranged, in the container handling process, the situation of bamboo-wood plywood cracking is arranged often.

The inventor analyzes, the research back is found, the reason that causes aforementioned cracking occurring is mainly for the chassis of container structure, and the container body underframe is generally three vertical, how horizontal structures.The bamboo-wood plywood of laying in the container body bottom surface generally is vertical laying.Just a plurality of cross-brace beams are transversely arranged, vertically generally have only two longitudinal bracing beams of both sides at bamboo-wood plywood.This just needs this product to have high bending strength and elastic modelling quantity in the vertical, transversely has high elastic modelling quantity.Otherwise will appear at when bearing big load (such as the fork truck deliver goods, wheel is in the bamboo-wood plywood lateral mid-point), bamboo-wood plywood causes the side slippage because of vertical, horizontal elastic modelling quantity deficiency, and then cracking occurs.

The utility model content

The utility model provides a kind of structural strength higher at above problem, and then can adapt to the bamboo wood glue mould assembling plate of instantaneous big load pressure.

The technical solution of the utility model is: the bamboo matter veneer and the stacked gummed of Wooden veneer that are divided into vertical and horizontal by the texture trend form;

Described boxboard comprises bamboo matter veneer, the bamboo matter veneer as base plate, at least three vertical veneer set layers and two the horizontal veneer set layers as top board, and described horizontal veneer set layer is arranged between described vertical veneer set layer; Outermost layer at vertical veneer set layer of top and bottommost adopts vertical Wooden veneer respectively.

Described bamboo matter veneer is bamboo curtain splint or bamboo mat.

Described vertical veneer set layer comprises at least five layers.

The set layer all adopts bamboo matter veneer in the middle of in described at least three vertical veneer set layers.

Described horizontal veneer set layer comprises the Wooden veneer of one deck at least and the bamboo matter veneer of mutual gummed.

Described horizontal veneer set layer is a bamboo matter veneer.

End face at described top board is provided with protection rete one; Be provided with protection rete two in the bottom surface of described base plate; Described protection rete is immersion non-woven fabrics, impregnated paper or bamboo mat.

The utility model has changed the structure of bamboo-wood plywood in the prior art, has taked on the assembly scheme with texture trend " set in groups ", again will be between " set " pattern of texture intersection assembly.In groups in the same way between the ply, the texture of material is chimeric mutually in pressing process, forms group effect, plays the effect of " the chopsticks folding is constantly ".To organize the horizontal stroke of " in groups " more again, vertically organize the staggered assembly of layer, finally make finished product bending strength and elasticity in the vertical increase greatly, transverse modulus of elasticity also significantly improves simultaneously.The utility model exquisite composition, bulk strength significantly improves under the situation of same material consumption.

The specific embodiment

Bamboo-wood plywood of the present utility model is shown in Fig. 1-5, and the bamboo matter veneer and the stacked gummed of Wooden veneer that are divided into vertical and horizontal by the texture trend form;

Described boxboard comprises bamboo matter veneer, the bamboo matter veneer as the base plate VII, at least three vertical veneer set layers and two the horizontal veneer set layers as the top board I, and described horizontal veneer set layer is arranged between described vertical veneer set layer; Outermost layer at vertical veneer set layer of top and bottommost adopts vertical Wooden veneer respectively.

Described bamboo matter veneer is bamboo curtain splint or bamboo mat.

Described vertical veneer set layer comprises at least five layers.

Described horizontal veneer set layer is a bamboo matter veneer.

End face in described top board I is provided with protection rete one VIII a; Be provided with protection rete two VIII b in the bottom surface of described base plate VII; Described protection rete is immersion non-woven fabrics, impregnated paper or bamboo mat.

First kind of embodiment of the present utility model as shown in Figure 1, among the figure as the 1st layer of the top board I, adopt horizontal bamboo mat as the 21st layer of base plate VII; 7th, 15 layers are adopted horizontal bamboo curtain splint; 2nd, 20,6,16 layers is vertical Wooden veneer; 3rd, 4,5,9-13,17,18,19 layers adopt vertical bamboo curtain splints.Wherein the 2-6 layer constitutes vertical veneer combination layer one II; 7th, 8 layers constitute horizontal veneer set layer one III; The 9-13 layer constitutes vertical veneer set layer two IV; 14th, 15 layers constitute horizontal veneer set layer two V; The 16-20 layer constitutes vertical veneer set layer three VI.Totally 21 layers, stacked in regular turn after, disposable gluing forms.The unshielded rete of this routine product is fit to have autonomous surface-treated client to use.
