CN2866067Y - Bamboo plywood for container floor - Google Patents

Abstract

The utility model provides a bamboo laminated wood as the base plate of container. In detail, it is comprised of hot-pressed front surface (1), core (2) and back surface (3), all of which are made of one or multiple pieces of laminated bamboo mat. The bamboo mat is a knitwork made from horizontal and vertical bamboo splints. Therefore, the utility model features high intensity, weather resisting property and lower price and can ease the situation of inadequate wood resource and contributes to ecological balance and environmental protection.

Description

The used for bottom plate of container bamboo plywood

Technical field

The utility model relates to glued board, especially composite board for bottom board of container.

Background technology

At present, composite board for bottom board of container mainly contains full wood and the compound two kinds of structures of bamboo wood.There are defectives such as intensity is low, weatherability difference in the container bottom board of full-wood.Particularly timber resources is very limited, one: the growth cycle of timber is long, needs at least just can cut down usefulness more than 30 years.Its two: countries in the world are for the needs of environmental protection and maintaining ecological balance, launch respectively limit and cut down even prohibit the policy of cutting down, and the wood supply amount is cut down greatly, cause price to rise violently thereupon.For this reason, composite bamboo-timber structure container bottom board with bamboo wood instead of part timber has appearred on the market, promptly with wooden plywood or oriented wood chipboard sandwich layer as base plate, table, backing layer bamboo wood, through operations such as gluing (or impregnation), hot pressing and moulding and make, there are shortcomings such as intensity is low, weatherability difference too in the container bottom board of this structure; And bamboo wood and timber are under same external force effect, its MOR, internal stress etc. are all inconsistent, and particularly the water absorption rate of bamboo wood and timber is inconsistent, under same environmental condition, its coefficient of expansion is also inconsistent, in use occurs easily coming unstuck, quality problems such as layering.

The utility model content

The purpose of this utility model provides that a kind of intensity height, weather resisteant are good, aboundresources, cheap used for bottom plate of container bamboo plywood.

For this reason, used for bottom plate of container bamboo plywood described in the utility model, be made up of hot pressing all-in-one-piece surface layer, sandwich layer and backing layer, each layer constitutes by one or the bamboo mat more than that overlaps together, and this bamboo mat is by the crisscross seat woollen yarn knitting structure that forms of bamboo chip.

The width of above-mentioned bamboo chip is preferably 30～50mm, and bamboo mat is preferably picked up two and given as security two oblique volume or vertical braiding structure, and the width of the used bamboo chip of surface layer is preferably less than the width of the used bamboo chip of backing layer.

The surface layer of glued board, sandwich layer and backing layer all adopt bamboo wood in the utility model.China's bamboo resource is abundant, and the growth cycle of bamboo wood is short, and its fibre strength height, good toughness are thought the substitute that timber is best by industry." wood substituted by bamboo " can alleviate the problem of timber resources anxiety, protects the limited forest reserves, helps the ecological balance and environmental protection.Compare with the glued board of composite bamboo-timber structure, the material of each layer of glued board described in the utility model is identical, and the water absorption rate of each layer is also identical, thereby under same environmental condition, the internal stress and the coefficient of expansion of its each interlayer remain unanimity, every physical and mechanical property unanimity of whole plate face.

The beneficial effects of the utility model are: intensity height, good weatherability; Long service life, cheap; The problem of wood raw material anxiety be can alleviate, the ecological balance and environmental protection helped.

Fig. 2 is the structural representation of bamboo mat 5 among Fig. 1.

The specific embodiment

As shown in Figure 1 and Figure 2, used for bottom plate of container bamboo plywood described in the utility model, be made up of hot pressing all-in-one-piece surface layer 1, sandwich layer 2 and backing layer 3, each layer constitutes by one or the bamboo mat more than that overlaps together 5, and this bamboo mat 5 is by the bamboo chip 4 crisscross seats woollen yarn knitting structures that form.Bamboo chip 4 is the fresh cizu of adopting lifes in 3 years above, Mianzhu etc., breaks into the bamboo piece of fixed length after go green grass or young crops, remove joint, is divided into certain thickness bamboo chip with thick layering machine calmly again.

The width that Fig. 2 illustrates bamboo chip 4 is 30～50mm, and bamboo mat 5 is given as security two oblique volume or vertical braiding structure for picking up two, not only guarantees its intensity but also be convenient to braiding, and the width of surface layer 1 used bamboo chip 4 makes the surface quality of surface layer better less than the width of backing layer 3 used bamboo chips 4.The also available elongated bamboo of bamboo chip 4 is fine to be replaced.Can be during use according to user's needs surperficial spray paint at glued board, or on surface layer 1, install the decoration panel of various patterns or texture additional.

Claims (2)

1, a kind of used for bottom plate of container bamboo plywood, form by hot pressing all-in-one-piece surface layer (1), sandwich layer (2) and backing layer (3), it is characterized in that: each layer constitutes by one or the bamboo mat more than (5) that overlaps together, and this bamboo mat (5) is by the crisscross seat woollen yarn knitting structure that forms of bamboo chip (4).

2, used for bottom plate of container bamboo plywood according to claim 1, it is characterized in that: the width of described bamboo chip (4) is 30～50mm, described bamboo mat (5) is given as security two oblique volume or vertical braiding structure for picking up two, and the width of the used bamboo chip of surface layer (1) (4) is less than the width of the used bamboo chip of backing layer (3) (4).
