However, the existing bamboo-based fiber composite board is limited by the production process, and the extending direction of the straight board of the bamboo-based fiber composite board must be the same as the arrangement direction of the bamboo fiber grains, so that the board with the whole length larger than the original length of the bamboo material cannot be prepared, the application of the new material in the field of large-scale buildings is limited, the new material can only be applied to small household and house structures at present, and the excellent mechanical property of the new material cannot be fully exerted; if knotting and drilling splicing are carried out on a plurality of bamboo-based fiber composite boards, bamboo fibers are broken and damaged inevitably, and the mechanical strength of the spliced part is reduced seriously. Therefore, a new feasible scheme is urgently needed to make a perfect breakthrough in order to solve the problem of length and size limitation in the existing bamboo-based fiber composite board preparation technology.

SUMMERY OF THE UTILITY MODEL

Not enough to among the above-mentioned prior art, the utility model provides a wavy bamboo base plate for realize the high strength concatenation of bamboo base fibre composite sheet, thereby break through the bottleneck of its length restriction.

The utility model discloses a following technical scheme implements: the utility model provides a wavy bamboo base plate, includes two bamboo base plates, a plurality of adhesive linkage, wherein, the end of bamboo base plate is the wave form to laminate with the wave end of opposite side bamboo base plate, the adhesive linkage fill in two the laminating clearance department of end.

Further, the utility model discloses still include two outer bamboo base plates, two the tip of outer bamboo base plate is wave form to laminate in two respectively the outside of bamboo base plate, simultaneously, be in the bamboo base plate with one side and the laminating of the board body between the outer bamboo base plate to laminate clearance department between bamboo base plate, outer bamboo base plate and be equipped with the adhesive linkage in the filling mode.

Furthermore, in the forming and curing stage of the bamboo base plate, the end part of the bamboo base plate is placed on a wavy die, and a press machine is used for applying pressure to the upper part of the bamboo base plate to form the end head in a wavy form.

Furthermore, the radian corresponding to each wavy arc of the wavy form of the end head is less than or equal to 0.5.

Furthermore, the material of the bonding layer is phenolic resin.

Furthermore, the bamboo base plate and the outer bamboo base plate are both made of bamboo-based fiber composite materials.

Furthermore, the outer surface of the bamboo base plate is superposed with the plane where the outer surface of the outer bamboo base plate on the other side is located.

The utility model has the advantages that: the utility model utilizes the joint butt joint of the wave form end and fills phenolic resin, so that two bamboo base plates are firmly and fixedly connected into a whole, simultaneously controls the arc radian of the wave arc of the end (less than or equal to 0.5), avoids the bamboo fiber from being broken, ensures that the bamboo fiber keeps the mechanical property under the reasonable bending degree, resists the external force in all directions through the bonding joint surface of the wave form, and can also be made into a multilayer structure that the bamboo base plates and the outer bamboo base plates are alternately clamped, thereby ensuring the mechanical strength of the butt joint of a plurality of bamboo base plates, overcoming the problems of length size limitation and butt joint difficulty of the prior art for the production of bamboo base fiber composite plates, ensuring that the bamboo fibers of the bamboo base plates can be spliced with high strength on the premise of ensuring the completeness and the damage of the bamboo fibers, thereby being applied to large buildings and industrial fields, breaking through the application bottleneck of the prior art, and greatly improving the applicability of bamboo base fiber composite materials, has good popularization and application values.

Detailed Description

The present invention will be described in further detail with reference to the drawings and examples.

As shown in fig. 1-2, a wavy bamboo substrate comprises two bamboo substrates 1, a plurality of bonding layers 2 and two outer bamboo substrates 3, wherein an end 1a of the bamboo substrate 1 is in a wavy form and is attached to a wavy end 1a of the bamboo substrate 1 on the other side, in the forming and curing stage of the bamboo substrate 1, the end of the bamboo substrate is placed on a wavy mold, a press is used for applying pressure to the upper side of the wavy mold to form the wavy end 1a, and the radian corresponding to each wavy arc of the wavy form of the end 1a is ensured to be less than or equal to 0.5, so that the integrity of bamboo fibers is ensured; the bonding layer 2 is filled in the joint gap of the two end heads 1a and is made of phenolic resin; the end parts of the two outer bamboo base plates 3 are also in a wave shape and are respectively attached to the outer sides of the two bamboo base plates 1, meanwhile, the plate bodies between the bamboo base plates 1 and the outer bamboo base plates 3 which are positioned on the same side are attached, and an adhesive layer 2 is arranged at the attaching gap between the bamboo base plates 1 and the outer bamboo base plates 3 in a filling mode; the outer surface of the bamboo base plate 1 is superposed with the plane of the outer surface of the outer bamboo base plate 3 on the other side, and the bamboo base plate and the outer bamboo base plate are both made of bamboo-based fiber composite materials.

Through the connection, the two bamboo base plates 1 and the two outer bamboo base plates 2 are butted to form a complete whole, when any one of the two bamboo base plates receives vertical, horizontal and oblique acting forces (the direction is according to the figure 1), the two bamboo base plates can bear and resist through the multilayer wavy bonding and adhering structure, and by analogy, the high-strength butt joint of the front end and the rear end of the plurality of bamboo base plates 1 is realized in the same way, so that the limitation of the length size of the bamboo-based fiber composite material is broken through.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various equivalents made by using the features of the claims of the present invention should fall into the protection scope of the present invention for those skilled in the art.
