Problems solved by technology

Due to the high density and high hardness of bamboo, there will be a problem of low bonding strength if it is directly glued to the shavings. This low-strength plywood cannot meet the strength requirements of the container for the bottom plate

Embodiment 1

[0046] Such as Figure 5 As shown, a kind of plywood 3 for the bottom plate of a container includes a pressure-bearing layer composed of one layer of particleboard 30, a veneer layer composed of 2 bamboo curtains 31 and 3 wooden veneers 32 arranged alternately, wherein, and Adjacent to the particleboard 30 is a wood veneer 32'. Considering that the requirements for the flexural strength of the bottom plate in the length direction of the container are higher than the requirements for the flexural strength in the width direction of the container, the wooden veneer 32 (32') in this example all adopts Long veneer along the grain.

[0047] The plywood 3 of present embodiment can adopt two kinds of methods when making:

[0048] Method 1: Glue the processed particleboard 30, wood veneer 32 and bamboo curtain 31 and press Figure 5 Embryos with the structure shown in , and then formed by hot pressing;

[0049] Method 2: Glue the wood veneer 32 and bamboo curtain 31 first, then pre...

Embodiment 2

[0057] Such as Figure 11 Shown, a kind of plywood 4 for container floor, this board includes the pressure-bearing layer that is made of two particle boards 40 and the wood veneer 43 that is sandwiched between two particle boards 40 and is made of two wood veneers 42 and two bamboo curtains 41 The veneers arranged alternately are wood veneers, and the veneers adjacent to the pressure-bearing layer are wood veneers 42 . Same as Example 1, considering that the requirements of the container for the flexural strength of the bottom plate in the length direction are higher than the requirements for the flexural strength in the width direction, the wood veneer 42 and wood veneer 43 in this example are all used in the same way as the container box The length direction of the body is consistent with the grain long veneer.

[0058] Such as Figure 12 shown in the Figure 11 Add a layer of bamboo mat 44 on the pressure bearing layer of the shown plywood to further enhance the pressure...

Abstract

The invention relates to a plywood used for a bottom board of a container, which comprises a bearing layer positioned on the upper part of the plywood and mainly used for bearing compressive stress and a single-board layer positioned on the lower part of the plywood and mainly used for bearing tensile stress. The bearing layer comprises a flakeboard and/or a fiberboard; the single-board layer comprises a wooden single-board and/or a bamboo single-board; the adjacent boards are connected by pressing and gluing. As the invention adopts anisomerous structure in design of every group of embryonic board for the bottom board of the container, the defect that the flakeboard and the fiberboard are poor in shearing resistance, bending resistance and tensile property is avoided, thus exerting the advantages of shearing resistance, bending resistance and tensile property of the wooden single-board and the bamboo single-board so as to greatly enhance the load bearing strength of the bottom board of the container.

Description

technical field [0001] The invention relates to a plywood, in particular to a plywood for the bottom plate of a container. Background technique [0002] As we all know, containers are widely used in the transportation industry because of their large capacity and heavy load. Among the components of the container, the wooden floor of the container is one of the important components. Such as figure 1 As shown, the container floor 11 generally adopts wooden plywood with an odd number of layers. In the JH / TD01 standard promulgated and implemented by the China Container Industry Association in 2002, it is stipulated that "the wooden floor must be at least 19 layers of plywood". One of the essences of plywood is to realize that the material of each corresponding veneer is arranged symmetrically along the direction of the grain with the center layer as the symmetrical plane, so as to achieve the consistency and stability of the mechanical properties of the plywood. Considering th...
