Description

[Detailed description of the invention] (Field of industrial application) This invention relates to wooden floor boards for containers on land and offshore.

(Prior Art) As Western-style floorboards for buildings, it is known that an undercoat layer is formed on the surface of a wooden substrate, and an intermediate coat layer containing mineral particles and a top coat layer are also formed on the surface ( (See Special Publication No. 51-35772).

(Disadvantages of the Prior Art) Although the Western-style floorboards for buildings are excellent in wear resistance due to the presence of mineral particles, they are not suitable for use as floorboards for containers for the following reasons. Nakatsuta. First, since no treatment was applied to the side circumferential surface of the wood-based substrate, cargo, such as raw eggs,
The drawback was that odor-like liquids such as spirits, oils, seafood, and animal hides penetrated into the substrate, leaving behind odors on the floorboards. Since this residual odor had penetrated into the wood-based substrate, it could not be easily eliminated by washing the floorboards with water. Second, since the surface of the floorboard, and more specifically the surface of the top coating layer, was smooth, the coefficient of friction with the cargo was small and the cargo easily collapsed. Thirdly, since it was simply a base coat layer formed on a wood-based substrate, it had the disadvantage that if the base coat layer was scratched, liquid would seep into the water-absorbing substrate through the scratches. .

(Purpose of the invention) The object of this invention is to eliminate the drawbacks of the Western-style floorboards and provide an extremely excellent floorboard for containers.

(Example) This invention will be described below based on an example shown in the drawings.

A wood-based substrate 1 such as plywood, sawn wood, particle board, laminated veneer, etc. shown in FIG. 1 is treated with insect repellent using a known insect repellent. Insect repellent treatment may be carried out by impregnating the surface or sides of the substrate 1 with an insect repellent, but in the case of plywood, particle boards, etc., insect repellent may be added to the adhesive used when manufacturing them. You may do so. The surface (upper surface) and side surfaces of the substrate 1 are impregnated with a synthetic resin paint having good permeability, and a first synthetic resin paint layer (including a film; the same applies hereinafter) 2 is formed thereon. As synthetic resin paints with good permeability, melamine resins, urea resins, phenolic resins, urethane resins, unsaturated polyester resins, acrylic urethane resins, acrylic resins, and modified resins thereof are used. Said first
A second synthetic resin paint layer in which abrasion-resistant mineral particles 3 are mixed into the surface and, if necessary, the side surfaces of the synthetic resin paint layer 2, and the mineral particles 3 make the surface rough with unevenness. 4 is formed. As the mineral particles 3, alumina, silica sand, agarite, etc. are suitable, and the particle size is preferably about 10 to 1000 μm. A known fungicide is mixed into the second synthetic resin paint layer 4.

Next, an example of use of the wooden floorboard 11 will be explained based on FIGS. 2 to 4.

As shown in FIGS. 3 and 4, the bottom frame of the container consists of left and right frame members 5 each having a substantially S-shaped cross section, and a rear frame member 5.
It has a front frame member 6 with a square cross section, a plurality of reinforcing bars 7 with a square cross section extending in the left-right direction, and a receiving bar 8 with a square cross section extending in the front-rear direction. A support member 13 having a square cross section is attached to each of the left and right frame members 5 and the rear frame member 5, and the floorboard is supported by the receiving portions 14 of these support members 13, the overhanging edge of the support bar 8, and the reinforcing bar 7. 11 is fitted into the bottom frame.
Note that step portions 12 are formed on the left and right bottom surfaces of the floorboard 11, into which the receiving portions 14 or the projecting edges of the receiving beams 8 enter. As shown in FIG. 4, a protection plate 16 for protecting the front part of the floorboard 11 is attached to the front frame member 6.
Pillars 9 are erected at the four corners of the bottom frame, and side walls 10 are erected between the pillars 9 except for the part where the front door 15 is provided.

(Effects of the invention) As described above, this invention brings about the following effects. First, not only the surface but also the side surfaces of the wood-based substrate 1 are impregnated with a synthetic resin paint with good permeability, and the first synthetic resin paint layer 2 made of the same is formed, so that the odor and odor of the luggage is eliminated. It is possible to prevent certain liquids from entering the substrate 1 and to prevent those odors from remaining in the container. Second, even if liquid or the like adheres to the floorboard, it will not penetrate into the substrate 1, so it can be easily removed by washing with water. Thirdly, the surface of the second synthetic resin paint layer 4 has mineral particles 3
Since it has a rough surface with unevenness, it can increase the coefficient of friction with the cargo and prevent the cargo from collapsing. Fourthly, since the wooden substrate 1 is impregnated with a highly permeable synthetic resin paint to harden its surface like a crust, it is difficult to get scratches that reach the center of the substrate 1. Even if there are scratches that reach the synthetic resin paint layer 2, the possibility of liquid infiltrating into the substrate 1 through the scratches is extremely low compared to conventional products. Fifth, since the first synthetic resin paint layer 2 covers the surface and side surfaces of the insect-repellent substrate 1, it is possible to prevent harmful insect repellents from escaping.
