ものである。Particularly, in the case of land transportation using a pallet carrier car or the like, it is necessary to keep the unevenness of the road surface small, so that the maintenance load on the road surface becomes large. Further, in the case of a ship, the ship has to be canceled due to bad weather, which not only adversely affects the transportation capacity and the transportation plan, but also causes a problem such as delay in delivery. By the way, for example, Japanese Utility Model Publication No. 53-20354 proposes a thick steel plate loading pallet for the purpose of avoiding sliding of the load and improving unsafe and inefficient cargo handling such as slinging work during shipping. .
As shown in FIGS. 12 and 13, this pallet is provided with a plurality of steel plate support plates 13 having a plurality of steps of steel plate receiving surfaces 13a and 13b sinking from the upper surface of a pallet body 11 having a rectangular planar shape. A plate retainer having a weight sufficient to generate a frictional force between the thick steel plates S to prevent sliding of the thick steel plates S laminated on the steel plate supporting plate 13 on the surfaces 13a and 13b.
Guide the 12 to the pallet body 11 by the self-weight and insert and guide the pin 18 into the hole 17 so that it can move up and down.

いう問題がある。However, in this thick steel plate loading pallet, not only is the device complicated and expensive, but when the width and thickness of the thick plates in the lot and the number of each plate change, the steel plate support plate 13 may be replaced. Or, it is necessary to take measures such as preparing several types of thick steel plate loading pallets each equipped with several types of steel plate supporting plates 13, which complicates the work and increases the cost for manufacturing several types of pallets. There is a problem of doing.

滑動を防止することができる。According to the present invention, a plurality of pairs of columns are vertically erected so as to face each other at least on both sides in the width direction of the four sides of the pallet board having a rectangular planar shape. Having a notch or a hole to be fitted at both ends in the width direction, a metal frictional restraint plate that is substantially restrained by the support except for movement in the vertical direction is provided between the support from above so as to be detachable and attachable. For each of several metal plates stacked in the pallet body, the friction restraint plates are stacked so that the notches or holes engage the columns, and the maximum number of stacked metal plates is set. A friction restraint plate having a notch or a hole at least in its upper portion is provided with a self-weight to generate a frictional force sufficient to prevent sliding of the uppermost metal thick plate between the uppermost metal thick plate and the uppermost metal thick plate. Since it is loaded so that it will engage with When transporting the cmdlet, metal planks by being bound most by the horizontal movement strut friction constraining plate against shaking during transportation, it is possible to prevent the sliding of the metal slab.

に防止される。Further, the frictional force acting between the friction restraint plate loaded on the uppermost part and the uppermost metal thick plate and between the uppermost metal thick plates causes the sliding of the uppermost metal plate. Can be effectively prevented. Naturally, the metal planks loaded in the lower part will receive the weight of the friction restraint plate and the metal planks loaded in the upper part, and the metal planks stacked in several layers will be loaded. Since a larger frictional force acts between the metal plate and the friction restraint plate than in the upper part, sliding of the metal plate loaded on the lower part is more effectively prevented.

ればよい。The number of the metal thick plates to be loaded with the friction restraint plates depends on the shape and flatness that affect the adhesion between the surfaces of the stacked metal thick plates and the material that affects the friction coefficient. Considering the thickness and unit weight that affect surface roughness and frictional force,
Further, it may be appropriately determined in consideration of the type of freight transportation means, traveling conditions, road surface conditions, or ship specifications and marine weather conditions.

The increase rate R f of the frictional force due to the upper friction restraint plate is given by the following (1)
It is shown by the formula. R f = μ i / μ o = n / (n-1) (1) where μ O is the friction coefficient between the metal thick plates and μ i is the increased friction coefficient.

In addition, the material, shape and dimensions of these friction restraint plates,
The weight and the like may be anything as long as a frictional force sufficient to prevent sliding of the metal thick plate as described above can be exerted between the metal thick plate in contact with the friction restraint plate and between the metal thick plates. Furthermore, it is desirable to select one that satisfies the following conditions.

Further, the frictional force acting between the friction restraint plate 5 and the uppermost metal thick plate 4 loaded on the uppermost part and between the uppermost metal thick plates 4 causes the sliding of the uppermost metal plate 4. Can be effectively prevented. Naturally, the metal thick plates 4 stacked below this will receive the weight of the friction restraint plate 5 and the metal thick plates 4 stacked above the metal thick plates 4, and several metal thick plates stacked in layers will be received. Since a frictional force larger than that acting on the upper portion acts between the friction restraint plate and the metal thick plate loaded for each of them, the sliding of the metal thick plate loaded on the lower part is more effectively prevented.

枚とするのが望ましい。By using the pallet substrate 1A and the friction restraint plate 5A which are constructed by adding the support columns 3A and the notches 6A in this manner, not only the rolling (rolling) but also the pitching (pitting) during the transportation of the pallet. Even with respect to the above, sliding of the loaded thick metal plates 4 in the width direction and the longitudinal direction can be effectively prevented. It should be noted that the friction restraint plate 5 (5A) used in the above-described embodiment has a length L F substantially equal to the length L P of the pallet substrate 1 for each layer.
Although the sheets are stacked one by one, the present invention is not limited to this. For example, as shown in FIG. 8, friction such that the length L F of the pallet substrate 1 is 1/2 or less of the length L P of the pallet substrate 1 is performed. A plurality of constraining plates 5B may be stacked for each layer. In this case, at least one pair / one notch 6 is provided in the friction restraint plate 5B, but two pairs or more / one is required to enhance the effect of restraining the sliding motion caused by the swing by the support column 3.
It is desirable to have one.

As shown in FIG. 9, holes 7 may be provided instead of the notches so as to engage with the columns 3. Further, the above-mentioned friction restraint plates 5 (5A, 5B) do not necessarily have to be stacked layer by layer, and are necessary in order to provide the frictional force necessary for preventing slippage of the thick metal plates stacked as described above. If there are multiple layers, they may be stacked.
