Composite board for bottom board of container
Technical field
The utility model relates to a kind of glued board, is specifically related to a kind of composite board for bottom board of container.
Background technology
As everyone knows, container is big because of its capacity, loading capacity is widely used in the carrier greatly, simultaneously, caused the problem of container cycle in service life minimizing also because the environment that container itself uses is comparatively complicated, abominable and cargo handling, transhipment frequent.And in the container building block, container wood floor is one of important part.Container wood floor generally adopts the wooden plywood of odd-level, China container industry association is in the JH/TD01 standard of issuing and implementation in 2002, regulation " timber apron is at least 19 layers of glued board ", one of this essence that requires for the container bottom board odd-level, be to realize that glued board is that the material and the rift grain direction of each corresponding veneer of the plane of symmetry is symmetry arrangement with the central core, to reach uniformity and the stability of glued board on mechanical property.In addition, container wood floor has the warranty in 5 years usually, this just has higher requirement to the quality of timber floor, especially require floor longitudinal load-bearing ability to want high, consider that for this reason container requires to be higher than requirement to bending strength on its width to base plate in the bending strength of length direction, as shown in Figure 1, on the arranging of veneer, three deck panels 101 on its surface, 102,103 and the Tipple Bottom plate 117 of bottom surface, 118,119 rift grain consistent with the length direction of container body (shown in four-headed arrow A among Fig. 1), the crisscross combination of all the other each layers, this kind design effectively raises container bottom board bearing capacity longitudinally on chassis of container, especially strengthened the tensile strength of timber floor base plate, but three layers on the surface of this kind design is because adjacent surface lacks horizontal pulling force, when climate change, surperficial ground floor to the three deck panels of plate very easily produce the crackle of 2-4mm, especially be covered with phenolic aldehyde on the surface on top layer, behind the thermosetting impregnated materials such as melamine, when running into dry weather, the situation of the easier appearance cracking in the surface on floor.
Summary of the invention
The utility model is intended to the problem at the prior art existence, designs a kind of composite board for bottom board of container, can reduce the cracking problem of floor surface, prolongs the service life on floor.
The utility model adopts following technical scheme:
A kind of composite board for bottom board of container comprises three deck panels, Tipple Bottom plate and the central layer between this face base plate, and this central layer comprises plate, band brachymedial plate in the rift grain length; The described ground floor panel that is arranged in top layer is that the long plate of rift grain, second layer panel are that band brachymedial plate, the 3rd deck panels are the long plate of rift grain, the continuous two-layer central layer adjacent with the 3rd deck panels be rift grain long in plate; Repressed gummed connects between the described adjacent flaggy.
Described composite board for bottom board of container, wherein, described Tipple Bottom plate is the long veneer of rift grain.
Described composite board for bottom board of container, wherein, the described ground floor base plate that is arranged in the bottom is that the long veneer of rift grain, second layer base plate are that band brachymedial plate, Tipple Bottom plate are the long plate of rift grain, and the continuous two-layer central layer adjacent with this Tipple Bottom plate is plate in the rift grain length.
Described composite board for bottom board of container, wherein, the surface of described ground floor panel has posted one deck thermosetting impregnated material layer.
Described composite board for bottom board of container, wherein, the veneer number of plies of forming this composite board for bottom board of container is 15~29 odd-level.
The composite board for bottom board of container of this structure, owing on the structure of three deck panels, adopt crisscross arrangement mode, the ground floor panel that promptly is arranged in top layer is that the long plate of rift grain, second layer panel are that band brachymedial plate, the 3rd deck panels are the long plate of rift grain, thereby increased lateral pull between the three deck panels adjacent surfaces, thereby effectively reduced the cracking problem of floor surface, prolonged the service life on floor.
Description of drawings
For further setting forth the utility model is technological means and the effect that the predetermined purpose of realization is taked, the utility model has been described in detail in conjunction with following accompanying drawing, the purpose of this utility model, feature and characteristics, can obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.
Below in conjunction with drawings and Examples the utility model is described in further detail.

The specific embodiment
Because utility model point of the present utility model is to form the group embryo mode of each veneer of glued board, therefore be not described in detail in following examples for concrete processing step such as processing steps such as gluing, hot pressing, and only the group embryo mode of each veneer be described.
The long veneer of rift grain in following examples is meant the veneer that lines is consistent with the length direction of container body, and band brachymedial plate is meant the veneer that lines is consistent with the width of container body.
Embodiment 1
As shown in Figure 2, a kind of composite board for bottom board of container, this plate is 19 layers of unsymmetric structure, the most surperficial ground floor panel 201 is the long veneer of rift grain, second layer panel 202 is a band brachymedial plate, the 3rd deck panels 203 be rift grain long in plate, the central layer 204,205 adjacent with the 3rd deck panels 203 for rift grain grow in plate; Bottom base plate is that ground floor base plate 219 and second and third layer base plate 218,217 are plate in the rift grain length; And other central layer: plate 207,209,211,213,215 and band brachymedial plate 206,208,210,212,214,216 adopted crisscross mode to arrange during rift grain was long; More than between the adjacent flaggy repressed gummed connect.
Embodiment 2
As shown in Figure 3, this plate is 19 layers of symmetrical structure, and the ground floor panel 301 on top layer is the long veneer of rift grain in this example, and second layer panel 302 is a band brachymedial plate, the 3rd deck panels 303 is the long veneer of rift grain, the central layer 304,305 adjacent with the 3rd deck panels 303 be rift grain long in plate; The ground floor base plate 319 of the bottom is the long veneer of rift grain, and second layer base plate 318 is a band brachymedial plate, and Tipple Bottom plate 317 is the long veneer of rift grain, the central layer 316,315 adjacent with Tipple Bottom plate 317 be rift grain long in plate; And other central layer: plate 307,309,311,313 adopted crisscross mode to arrange with band brachymedial plate 306,308,310,312,314 during rift grain was long, more than repressed gummed connection between the adjacent flaggy.
Embodiment 3
As shown in Figure 4, the difference of this example and example 1 is, compound one deck thermosetting impregnated material 42 on the ground floor panel 201 of this plate, and this kind thermosetting impregnated material can be phenol glue water or melamine glue water retting material.
Equally, also can be on the ground floor panel of example 2 compound one deck thermosetting impregnated material, this kind thermosetting impregnated material can be phenol glue water or melamine glue water retting material.
Based on the known technology of this area as can be known, the veneer number of plies of forming composite board for bottom board of container can be 15~29 odd-level, and therefore 19 layers among the above embodiment are only for illustrating, and the group embryo mode of other number of plies does not repeat them here.
