Abstract

The invention discloses a composite bottom board for a container, which is formed by stacking and gluing a plurality of veneers; and the composite bottom board comprises an upper surface layer, a lower surface layer and a middle layer sandwiched between the upper surface layer and the lower surface layer. Through reasonable structural design, on the promise of ensuring that the performance of the bottom board can meet the usage requirement of the container, the log resources are better utilized so as to obtain high-quality face/bottom boards; and the laying-up mode of the traditional bottom boards for the container is changed, current log resources are more effectively utilized, the contradiction between the supply and requirement of the log resources is relieved, and the manufacturing cost of the bottom board for the container is reduced.

Description

A kind of container composite bottom board
Technical field
The present invention relates to a kind of composite bottom board, relate in particular to the composite bottom board that a kind of container is used.
Background technology
The panel of container bottom board all adopts plate in the length all the time, promptly with the veneer of panel texture chassis of container parallel longitudinal, its main cause is to strengthen the base plate longitudinal strength to satisfy the requirement that container uses, since the characteristics determined of chassis of container the longitudinal strength of container bottom board be greater than transverse strength, therefore mainly contain 3 * 3 or 3 * 2 structures in traditional container bottom board structure, its main purpose all is to be positioned over the outermost of base plate to strengthen the longitudinal strength of base plate for plate during rift grain is long.When rounding became veneer, the log length direction was exactly the rift grain direction of veneer, and log length is short more, its rotary-cut resistance is less, veneer view picture rate is relatively also higher, therefore, in the daily production, the length that reduces veneer rift grain direction helps obtaining the higher veneer of view picture rate.
Traditional structure require backplate surface need view picture rate height, rift grain that surface quality is good long in plate as panel, still be that tropical hard wood all will face a same difficult problem no matter use fast growing wood at present, the volume recovery that rotary-cut goes out to satisfy plate in the length that the face base plate uses is lower, the very big puzzlement that this brings for timber apron enterprise, some enterprise even stop production because the quality of face base plate can't reach requirement and have to.Simultaneously the continuous three layers of rift grain in surface long in plate reduced the intensity of surperficial band direction, cause tiny slight crack easily in the surface and the bottom surface of base plate, shortened base plate service life greatly.
Therefore, under forest reserves background in short supply day by day, how under the prerequisite that guarantees the container bottom board requirement of strength, improve constantly the base plate self performance, more effectively utilize timber resources, become the container bottom board producer and researcher's urgent problem.
Summary of the invention
In view of above specification requirement, the invention provides the rational container composite bottom board of a kind of project organization, guarantee that base plate performance satisfies the container instructions for use, prolong base plate service life, and can obtain high-quality base plate to reduce the production cost of base plate by the better utilization log resource.
For achieving the above object, the present invention uses following technical scheme:
A kind of container composite bottom board, form by the stacked gummed of several veneers, this composite bottom board has comprised upper epidermis and following top layer, and be clipped in intermediate layer between upper epidermis and the following top layer, it is characterized in that, the outermost layer veneer of described upper epidermis is a face crossing, adjacent with the outermost layer veneer is plate in the 1-4 layer rift grain length, described down top layer include at least a face crossing and a rift grain long in plate, described intermediate layer includes and is no less than the continuous stacked ply of plate in 4 rift grains length, and described intermediate layer and upper epidermis and the intermediate layer veneer adjacent with following top layer is a face crossing.
In the present invention, constituting described container is one deck face crossing with the outermost layer on the following top layer of composite bottom board, adjacent with the outermost layer veneer be 1-4 layer rift grain long in plate.
In the present invention, constituting described container is veneer and/or bamboo veneer with the veneer of composite bottom board.
In the present invention, described veneer comprises veneer and bamboo veneer, and accompanies one deck veneer at least between the adjacent two bamboo veneers.
In the present invention, described upper epidermis and/or down top layer outermost layer veneer top finishing one deck functional resin is arranged or posts at least one deck Tetefol or post one deck resin immersion non-woven fabrics at least.
In the present invention, the described upper epidermis and/or the outermost layer veneer process resin impregnation process on top layer down.
In the present invention, plate all can go out the specification that requirement is used by the direct rotary-cut of log during described face crossing and described rift grain were long, also can use the less veneer of specification to use methods such as overlap joint, finger, butt joint to be spliced into desired specification in identical grain direction.
In the present invention, described covering with paint functional resin layer or Tetefol layer or immersion non-woven fabrics layer are provided with the wood grain anaglyph, and the texture of wood grain embossment is vertical with the grain direction of upper epidermis outermost layer veneer.
In the present invention, described functional resin layer is covered with paint, lacquer, colour wash, etc. in the outer surface of the outermost layer veneer on described upper epidermis and/or following top layer, perhaps described Tetefol or resin immersion non-woven fabrics are laminated in the described upper epidermis and/or the outer surface of the outermost layer veneer on top layer down, with the veneer of applying glue, assembly through once hot-forming.
In the present invention, employed veneer can be wooden veneer, adopt more than any one or two kinds of seeds in poplar, pine, the eucalyptus, also can be artificial fast growing wood mixes with the higher tropical deciduous species of density such as clone, Marasse, beech, red Lan Ren, birch, oak, toothed oak wood, leatherleaf Pometia spp etc.
Compared with prior art, the present invention has following beneficial effect:
(1) container of the present invention uses face crossing effectively to strengthen the transverse strength of base plate with the composite bottom board surface, the veneer adjacent with upper and lower dash board all used rift grain long in plate to remedy longitudinal strength, the intermediate layer has used the method for the lamination of plate in the multilayer rift grain length can better strengthen the longitudinal strength and the shear-stable ability of base plate, better guarantees the base plate overall performance.
(2) container of the present invention uses face crossing with the composite bottom board surface, guarantee that base plate can not gone out to cracking phenomena by the rift grain direction (being the chassis of container horizontal direction) of Face veneer, be guaranteed owing to the base plate longitudinal strength simultaneously, the band direction of backplate surface veneer (being the chassis of container longitudinal direction) also is not easy to occur cracking phenomena, make backplate surface not easy to crack, prolong base plate service life.
(3) container of the present invention can use the higher face crossing of view picture rate as panel with composite bottom board structure, better utilization timber resources, reduced the production cost of container timber apron.
