Abstract
The utility model discloses a plywood used for a bottom plate of a container, which is formed by a plurality of layers of single plates by gluing pressing and comprises an upper surface layer, a lower surface layer and a middle layer between the upper surface layer and the lower surface layer; both the upper surface layer and the lower surface layer comprise single plates with longitudinal grains and single plates with transverse grains, and the upper surface layer sequentially comprises one to two layers of single plates with longitudinal grains, one layer of single plate with transverse grains, two layers of single plates with longitudinal grains and one layer of single plate with transverse grains. The plywood used for the bottom plate of the container changes the structural characteristics of the bottom plate of the traditional container by adopting the method of continuously laminating a plurality of layers of single plates with longitudinal grains, thus guaranteeing the shearing strength of the middle layer of the bottom plate, reinforcing the bending strength of the whole bottom plate, and well meeting the harsh requirement of the bottom plate of the container on strength.
Description
Technical field
The utility model relates to a kind of glued board, relates in particular to a kind of composite board for bottom board of container.
Background technology
The structure of container bottom board mainly is meant the distributing order of interior face crossing of container bottom board and rift grain veneer, mainly contain 3 * 3 or 3 * 2 structures in traditional container floor structure, promptly use plate laminated in continuous 3 layers of rift grain length on upper and lower top layer, according to the characteristics of container bottom cross beam, 3 * 3 or 3 * 2 its main purposes of structure all are that plate in the rift grain length is positioned over the outermost on floor to strengthen the floor longitudinal strength.But, minimizing along with the forest reserves, the utilization that some defectiveness materials, bamboo wood, speed are given birth to is also more extensive, utilization for timber has begun constantly deeply, after bamboo becomes bamboo curtain splint veneer or bamboo mat veneer, the became uneven of veneer own, artificial forest fast growing wood be because the low became uneven of veneer and the problem that veneer need splice of also existing of veneer view picture rate, thereby tend to cause container bottom board folded core to occur and from superficial defects such as cores according to traditional structure production; Simultaneously, traditional structure is produced container bottom board, to having relatively high expectations of veneer, and the stock utilization wretched insufficiency.
The mid portion of plate structure is mainly based on crisscross between the veneer traditionally, also only the method for having used continuous 3 layers of rift grain lamination middle in 3 * 3 structures, loading characteristic and mechanics principle according to container bottom board, its intermediate layer is subjected to shearing force bigger, therefore in the utilization of carrying out fast growing wood and bamboo wood, fast growing wood and defective timber self wood property is stable inadequately, and the harder difficult gummed of bamboo wood, if therefore adopt crisscross mode to carry out assembly in a large number, can cause mutual failure by shear between the mid portion veneer, defectives such as integral bending is relatively poor, this will be unfavorable for bamboo wood and fast growing wood making full use of in container bottom board production.On the patent gazette, also announced some in recent years, used 3 * 3 or 3 * 2 such tactic patterns but all fail to break away from container bottom board in the traditional structure with regard to its essence about the relevant patent of bamboo wood composite veneer as container bottom board.
Under forest reserves background in short supply day by day, how to pass through structural design better utilization material resources, the stabilizing material performance, improve its utilization rate, satisfying under the container bottom board instructions for use, reduce the material cost of container bottom board, become the problem that the container bottom board researcher presses for solution.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, a kind of composite board for bottom board of container is provided, changes original container bottom board design feature, improve container bottom board raw-material utilization rate, reduce the superficial defects of container bottom board, satisfy the requirement of strength of container bottom board.
For achieving the above object, the utility model uses following technical scheme: a kind of composite board for bottom board of container is provided, form through the gummed compacting by the multilayer veneer, comprise upper layer, following surface layer and be clipped in described upper layer and described intermediate layer between the surface layer down, it is characterized in that, described upper layer and following surface layer all include rift grain veneer and face crossing, and described upper layer is followed successively by 1-2 layer rift grain veneer, 1 layer of face crossing, 2 layers of rift grain veneer, 1 layer of face crossing from outside to inside.
In the utility model, described intermediate layer is formed by the rift grain veneer continuous stratification that is no less than 4 layers.
In the utility model, be the center with described intermediate layer, the veneer in the described surface layer is down arranged and the veneer of described upper layer is arranged symmetrical.
In the utility model, described upper layer and/or following surface layer outermost layer veneer surface are provided with one deck watertight composition or decorative layer.
In the utility model, described watertight composition or decorative layer are provided with the anaglyph of wood grain or asperities.
Compared with prior art, the beneficial effects of the utility model are: the surface layer to container bottom board carries out appropriate design, reduce and become the demand of traditional container bottom board structure the surface material of quality high requirement, improved the utilization rate of material, reduce the superficial defects of composite board for bottom board of container, thereby reduced the material cost of container bottom board; Change the design feature of traditional container bottom board by the method for multilayer rift grain veneer continuous stratification, guaranteed the shear strength in base plate intermediate layer, strengthen the bending strength of base plate integral body, better met the harsh requirement of container bottom board intensity.
