Abstract

A kind of plate of material, by interconnective, preferably by gluing the layer constitute, wherein at least one the layer constitute by bamboo.This plate of material is made of pole section or fragment complete, that vertically rived.A plurality of bamboo layers can be alternately by gluing.

Description

The plate of material that constitutes by bamboo

The present invention relates to a kind of by plate of material interconnective, that preferably constituted by the layer of gluing.

In the scope of this specification, notion " layer " is used for as lower area: these zones have nothing in common with each other on structure and/or material, and are separated from one another even these zones are not strict level land.

With regard to its structure, plate of material can be divided into lamina and multi-layer sheet.The most known lamina is particieboard, OSB plate, hard fiber board and medium density fibre board (MDF) (MDF).Multi-layer sheet is made of a plurality of flat mutual bonding layers usually, and the machine direction of these layers is interlaced with each other.The most common multi-layer sheet is glued board and composite plate.All these known plates all by wood as stock, this stock otherwise with the form of solid wood layer by gluing, or with the form of smear metal or fiber by gluing.But also have in addition a lot of special shapes, mixed form (for example deck plate etc.) and with the combination of plastics, metal etc.

Because multiple favourable characteristic, for example higher shape stability, the machinability of improvement, lower cost, the solid wood of unique use before these plate of material have replaced in most of applications.Yet the plate of material of still not having all advantages that have these known material sheet will concurrently so far.Plate heaviness and shape stability with low cost are poor.The plate of dimensionally stable is expensive and heavy.

Therefore the objective of the invention is to, design a kind of plate of material, it has a plurality of advantages of known material sheet will concurrently.

According to the present invention, this point is achieved by following measure, and promptly this plate of material is made of two or more layers, and wherein at least one layer is made of bamboo.

According to of the present invention preferred embodiment a kind of, the bamboo layer is the intermediate layer, and this intermediate layer is connected with each layer as top layer that is made of another kind of material respectively in both sides.According to another preferred embodiment, the bamboo layer is made of bamboo pole complete or that rive, smear metal or fragment.According to another preferred embodiment, the intermediate layer is made of the bamboo smear metal, and these bamboo smear metals are adopted OSB to be provided with or arbitrarily are provided with spuiously.According to another preferred embodiment, a plurality of intermediate layers are made of bamboo, and these intermediate layers are bonding mutually alternately, i.e. the mutual deflection of their fiber orientation.

Plate of material of the present invention has the lot of advantages of known material sheet will: it is dimensionally stable, light and with low cost simultaneously, but also owing to additional characteristic has advantage.Bamboo is light, simultaneously than the wooden tension of in most cases using so far.In addition, bamboo is a kind of raw material rapid, with low cost and that be easy to get of producing.

Contrast description of drawings the preferred embodiments of the present invention below.Shown in the figure:

Fig. 1 is the schematic partial perspective cutaway view with the plate of material in an intermediate layer that is made of bamboo pole;

Fig. 2 has a corresponding schematic diagram by the plate of material in the intermediate layer that is constituted by the bamboo pole of being rived;

Fig. 3 is the corresponding schematic diagram with the plate of material in an intermediate layer that is made of the bamboo fragment;

Fig. 4 is for having two corresponding schematic diagrames by the plate of material in the intermediate layer that is constituted by the bamboo fragment of (gesperrt) gluing alternately;

Fig. 5 is the corresponding schematic diagram with the plate of material in an intermediate layer that is made of the bamboo fragment that adopts OSB to be provided with.

Plate of material shown in Fig. 1 constitutes by three layers, or rather, is made of an intermediate layer 1 and two top layers 3, and described intermediate layer is made of the bamboo pole 2 that is arranged side by side, described top layer 3 by wood-fibred for example the so-called medium density fibre board (MDF) of class (MDF) constitute.These bamboo poles interconnect, and are connected by fiber-glue mixture with top layer.

Manufacture process is as follows: will two fleece reeled yarns that constitute by fiber and glue (

) between the bamboo layer extend into or be inserted in the forcing press, and with these the layer compress mutually.Thus the material of top layer partly is pressed in the intermediate space between bamboo pole.According to this embodiment, the inner space of pole does not have glue.Make that thus the weight of plate is low weight.With dashed lines 4 illustrates the appearance profile line of bamboo pole 2 in Fig. 1.

Alternatively, top layer 3 can be made of solid wood (thick china), and other monolayer material plate is wood-fiber board for example, and multilayered material sheet is glued board, composite plate etc. for example, by plastics for example melmac, phenolic resins etc. constitute, perhaps by metal for example aluminium etc. constitute.Also other top layer can be applied on the fibrage 3.

Because the endwise tensile strength of bamboo fiber is higher, so this plate has extra high flexural strength.Bamboo pole plays the reinforcement effect to plate of material.Therefore, also can make the shelf (Tablare) that is used for big load that does not almost have bending.

Plate of material shown in Fig. 2 has intermediate layer 2, and this intermediate layer 2 is made of the bamboo pole section 5 that vertically is divided into four parts.Under concrete condition, can be provided with obviously intensively for these loose sections that illustrate for the purpose of understanding among the figure.Need the less fibrous material that is mixed with glue thus, and realize that weight is lighter.In addition, the bamboo layer adopts the mode identical with embodiment shown in Figure 1 to be connected with top layer, that is to say that intermediate space partially or fully is filled with quilting material.

Plate of material shown in Fig. 3 is made of intermediate layer 1, and this intermediate layer 1 is made of the bamboo smear metal or the fragment 6 of substantially parallel setting.These smear metals or fragment are either large or small, and length has nothing in common with each other.Length can be 5mm-5m, but preferred size is between 10cm and the promptly about 1-2m of the board size order of magnitude.

Embodiment shown in Fig. 4 has two intermediate layers 7,8 that are made of bamboo smear metal or fragment 6, and these two intermediate layers be that is to say by gluing alternately, the machine direction in two intermediate layers 90 ° of angles of staggering mutually.The tensile strength of plate on two orthogonal directions is bigger thus.

Replacement to two by the bamboo smear metal of alignment or being crisscross arranged of the intermediate layer that constitutes of fragment, according to another schematically illustrated among Fig. 5 embodiment, in intermediate layer 1, adopt the mode of OSB plate to be provided with flat bamboo smear metal 9, and make that these bamboo smear metals 9 are bonding mutually along different directions.Utilize a unique intermediate layer just to make plate of material on different directions, have the bending strength of raising thus.

Plate is widely used in timber industry, for example is used for furniture design and component design, and the semi-finished product that are used as different field.
