JPS5848427B2 - Floor panel structure for containers, etc. - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a floor panel structure for a container, etc., which is easy to manufacture, has excellent strength, can be nailed to secure cargo, etc., and can be adjusted to the position of the beam members. It is characterized in that it can be easily installed even if there are some errors, and that it can be easily repaired and replaced even if it is damaged.

Traditionally, a wood called apiton has been used exclusively as flooring material for containers.

Wood as a flooring material has the advantage of being easy to work with and can be nailed, etc., but it is difficult to construct a flooring material by arranging wood of a certain quality, and it is time-consuming to join them together. Furthermore, it has the disadvantage of being easily influenced by temperature, humidity, etc.

Furthermore, wood resources are in short supply these days, making it difficult to obtain high-quality wood and making it expensive.

The present invention eliminates the above-mentioned drawbacks, and the floor panel is mainly composed of metal plates.

The use of metal plates has stable quality and strength, but there are drawbacks such as the fact that it generally requires a lot of work, such as welding, to manufacture, and furthermore, it cannot be nailed to secure cargo, etc.

Furthermore, if the device is manufactured by welding or the like, it requires a lot of effort to repair and cannot be replaced.

The present invention eliminates the above drawbacks,
As already mentioned, it is easy to manufacture, has excellent strength, can be nailed, and has the advantage of being extremely easy to repair and replace.

That is, in the present invention, grooves are formed by pressing or the like at appropriate intervals around the periphery and center of the upper metal plate, and the lower surface of the grooves is brought into contact with the lower metal plate to overlap, and a piece of wood or the like is placed in the groove. It is characterized in that a nailable member is fitted, and bolts or the like are inserted from the nailable member into the groove of the upper metal plate and the lower metal plate to fix it to the beam member.

One embodiment will be described in detail below with reference to the drawings.

Concave grooves 2 are provided at appropriate intervals around the periphery and center of the upper metal plate 1 by pressing or the like.

As shown in the second figure, the groove 2 preferably has an inverted trapezoidal cross section, and is located at a position compatible with the beam member 3 provided in advance.

Although the details of the beam members 3 are not shown in the drawings, there are side beams, cross beams, end beams, etc.

Next, the lower metal plate 4 is brought into contact with the lower surface of the groove 2 of the upper metal plate 1 to overlap.

In the present invention, the abutting and overlapping surfaces of the upper metal plate 1 and the lower metal plate 40 are not fixed together by welding or the like.

Therefore, as will be described later, even if the upper metal plate 1 or the like is damaged, it can be easily replaced.

Furthermore, a nailable member 5 such as wood is fitted into the groove 2 of the upper metal plate 1.

The nailing member 5 has a cross section similar to the cross section of the groove 2, and is provided so as not to protrude from the upper surface of the upper metal plate 1.

Next, bolts 7 are inserted from the nailable member 5 into the groove 2 of the upper metal plate 1 and the lower metal plate 4 to be fixed to the beam member 3.

That is, a through hole 8 is provided in the bottom of the groove 2 of the upper metal plate 1 and a through hole 9 is provided in the lower metal plate 4, through which a bolt 7 is inserted and screwed and fixed to the beam member 3.

In the present invention, the through holes 8 and 9 are preferably made slightly larger in diameter than the bolt 7, and are configured as so-called blank holes.

As a result, even if there is some error in the arrangement positions of the upper metal plate 1, the lower metal plate 4, and the beam member 3, they can be easily attached, and no looseness will occur when they are attached.

That is, in the present invention, since the upper metal plate 1 and the lower metal plate 4 are tightened to the beam member 3 by the nailing member 5 and the port 7 fitted in the groove 2 of the upper metal plate 1, the through hole 8
Even if 9 and 9 are used as stupid holes, the upper metal plate 1 and the lower metal plate 4
is completely fixed.

As mentioned above, the floor panel of the present invention is provided with the groove 2 in the upper metal plate 1, and is fixed to the beam member 3 by the nailing member 5 fitted in the groove 2, so that cargo etc. It is also possible to nail it to secure it in place.

Furthermore, when a load is applied to the upper surface of the upper surface metal plate 1, the concave grooves 2 serve as reinforcement against bending, etc., and the load is also
As shown by the arrows in the figure, the beam is divided and transmitted to the beam member 3, creating a canceling state and having an excellent effect in terms of strength.

Furthermore, according to the present invention, it is easy to manufacture without requiring work such as welding, and there are no welded parts, so even if the top metal plate 1 is damaged, it can be easily repaired or replaced. It is.
