Exemplary embodiments according to the present utility model will now be described in more detail with reference to the accompanying drawings.
A first aspect of the utility model provides a container floor 100. The container floor 100 includes a structure 120 and a facing layer 110 attached to an upper surface of the structure 120. Wherein the structure 120 is constructed in a multi-layer structure having n layers. The (n+1)/2 th layer is configured as a central layer when the total number of layers of the structure 120 is singular, or the n/2 th layer and the (n+2)/2 th layer are configured as central layers when the total number of layers of the structure 120 is double. The structure 120 includes two first transverse wood veneer layers 121, one second transverse wood veneer layer 122, and a plurality of longitudinal bamboo curtain layers 123. Two first transverse wood veneer layers 121 are provided on the 2 nd and n-1 th layers of the structure 120. The second transverse wood veneer layer 122 is disposed between the first transverse wood veneer layer 121 located at the 2 nd layer and the center layer. The 3 rd through n-2 th layers of the structure 120 except for one second transverse wood veneer layer 122 are each constructed as a longitudinal bamboo curtain layer 123. The thickness of the longitudinal bamboo curtain layer 123 is greater than the thickness of the transverse wood veneer layer. The thickness of the longitudinal bamboo curtain 123 is 2.3-2.5mm.
Compared with a bamboo curtain layer, the wood veneer (namely wood) layer has long wood forming period and high price, so that the wood consumption and the cost can be reduced by reducing the number of layers of the wood veneers, meanwhile, the consumption of the wood veneer adhesive (such as phenolic resin) is large, the consumption of the longitudinal bamboo curtain layer adhesive is small, and the consumption of the adhesive can be reduced by reducing the number of layers of the wood veneers, so that the cost is further reduced. The utility model optimizes the structure of the bottom plate of the existing container, increases the thickness and the number of layers of the longitudinal bamboo curtain layers, reduces the number of layers of the wood veneer, reduces the wood consumption and the adhesive consumption, reduces the cost, is beneficial to environmental protection, and simultaneously ensures that the horizontal wood veneer layers and the longitudinal bamboo curtain layers are arranged in a laminated manner so as to ensure that the longitudinal and transverse physical properties are balanced.
As is known, the thickness of the longitudinal bamboo curtain layer 123 in the container bottom plate of the present utility model is greater than that of the longitudinal bamboo curtain layer 123 in the prior art, so that the container bottom plate 100 with the same thickness requirement can reduce the number of layers of the wood veneer layer, i.e. the usage amount of wood can be reduced. The thickness of the longitudinal bamboo curtain 123 can be flexibly set according to actual production conditions, use requirements and the like.
It should be noted that the finish layer 110 does not account for the number of layers of the container bottom plate 100 in the present utility model.
In particular, the container floor 100 of the present utility model will be further described with reference to FIG. 1. The container floor 100 is formed from the layers of the structure 120 and the facing layer 110 by one-time thermo-compression molding. Wherein, the structure 120 is constructed as a multi-layer structure (ply 1-ply 19) having 19 layers, wherein the tenth layer (ply 10) is a central layer, and the structure 120 has the following structures from top to bottom: the first layer (ply 1) is a longitudinal wood veneer layer 124, the second layer (ply 2) is a first transverse wood veneer layer 121, the third to seventh layers (ply 3-ply 7) are longitudinal bamboo curtain layers 123, the eighth layer (ply 8) is a second transverse wood veneer layer 122, the ninth to seventeenth layers (ply 9-ply 17) are longitudinal bamboo curtain layers 123, the eighteenth layer (ply 18) is a first transverse wood veneer layer 121, and the nineteenth layer (ply 19) is a longitudinal wood veneer layer 124.
Preferably, adjacent longitudinal bamboo curtain layers 123 are arranged in a head-to-tail and crossed manner. The uniformity of glue amount during glue application can be further ensured due to the head-to-tail reverse and forward cross arrangement between the adjacent longitudinal bamboo curtain layers 123 during glue application. Thus, the glued container bottom plate 100 has a structure in which adjacent longitudinal bamboo curtain layers 123 are arranged in a head-to-tail reverse and crossed manner.
The transverse physical properties (e.g., transverse static bending strength and transverse elastic modulus) of the container floor 100 of the present utility model are primarily contributed by the transverse wood veneer layers, and the rational layout of the second transverse wood veneer layers 122 may better balance the transverse and transverse physical properties of the container floor 100. In the above-described structure 120 constructed in 19 layers, the second transverse wood veneer layer 122 may be located in the 8 th layer or any one of the 3 rd to 9 th layers, and may be flexibly selected according to actual production conditions, use requirements, and the like.
The thickness of the transverse wood veneer layer may be 1.6-1.8mm. Specifically, the thickness of each of the first and second transverse wood veneer layers 121 and 122 may be 1.6-1.8mm. The thicknesses of the first and second transverse wood veneer layers 121 and 122 may be flexibly set according to actual production conditions, use requirements, and the like.
Alternatively, at least one of the 1 st and n-th layers of the structure 120 is configured as a longitudinal wood veneer layer 124, and the thickness of the longitudinal bamboo curtain layer 123 is greater than the thickness of the longitudinal wood veneer layer 124. In the preferred embodiment shown in fig. 1, layers 1 and 19 are each longitudinal wood veneer layers 124, it being understood that one of layers 1 and 19 may also be a longitudinal wood veneer layer 124. The 1 st and nth layers of the structure 120 are preferably each constructed as a large-format longitudinal wood veneer. Compared with the wood veneers commonly used in the prior art, the large-format longitudinal wood veneers do not need to be glued, so that the consumption of glue (such as phenolic resin glue) and labor cost can be reduced.
The thickness of the longitudinal wood veneer layer 124 may be less than the thickness of the transverse wood veneer layer. In the above-mentioned structure 120, the number of layers of the longitudinal bamboo curtain layer 123 is large and the thickness is large, that is, the longitudinal bamboo curtain layer 123 can greatly contribute to physical performance indexes such as static bending strength in the longitudinal direction and elastic modulus in the longitudinal direction, and accordingly, the thickness requirement of the longitudinal wood veneer layer 124 can be relatively reduced. The thickness of the longitudinal wood veneer layer 124 is preferably 0.7-0.9mm. The thickness of the longitudinal wood veneer layer 124 may also be flexibly selected according to the actual conditions, the use requirements, and the like.
The facing layer 110 may be an impregnated paper layer. The thickness, material, etc. of the impregnated paper layer are not particularly limited in the present utility model.
The utility model optimizes the structure of the bottom plate of the existing container, reduces the number of layers of the wood veneer layer, increases the thickness of the longitudinal bamboo curtain layer, reduces the wood consumption and is beneficial to environmental protection.
In addition, the container bottom plate provided by the utility model has stable physical properties, and all performance indexes are superior to the national standard requirements and industry standard requirements of the container bottom plate.
