DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet used for transferring building materials such as panels.

[0002]

2. Description of the Related Art In order to transfer building materials such as panels from a factory to a construction site, for example, various materials are loaded on a pallet in advance, mounted on a truck by a forklift or the like, and transported to the construction site. As a pallet used for such transportation, there has been no standardized pallet in the past, and various pallets are used according to the size and shape of the material. That is, for example, as shown in FIG. 6, a pallet 1 which can be stacked up and down, a basket-like pallet 2 provided with an enclosure by a wire mesh, and a pallet 3 comprising a bottom plate and side plates
Is used as appropriate for the material and is transported by truck. Here, for example, the pallet 1 is
a and a column 1b provided on the side of the column 1a. The bottom of the column 1b has a fitting leg 1c fitted to the column 1b when the pallet 1 is stacked on another pallet 1. Things.

[0003]

However, such a pallet has the following disadvantages. When transporting building materials using the pallets, when loading these pallets on the truck bed, since the size and shape of each pallet varies, it is difficult to know how much can be loaded unless it is actually loaded on the bed. In addition, the loading capacity varies depending on the skill of loading, so it takes time to load.

Generally, pallets of the same kind can be stacked one on top of the other, but cannot be stacked by different kinds of pallets. Therefore, it is very difficult to efficiently load them on a truck bed of a limited space. is there. That is, as shown in FIG. 6, various pallets are used according to the size of the material, etc., but there is not always a material having the same size as the height of the truck bed.
For example, when there are some long materials, they are loaded using the pallet 1 in FIG.
The pallet on top of the pallet will be of the same kind, so if there is no other long material, another material that does not originally need the length of the pallet 1 will be loaded,
As a result, the loading efficiency on the truck is reduced.

In the pallet 1 shown in FIG. 6, when the pallets 1 are stacked one upon another with materials loaded thereon, the pallets 1 are naturally moved by a forklift or the like, but as shown in FIG. The position of 1c is exactly the column 1
If the pallets 1 and 1 are not placed on the pallets 1 and 1, the fitting legs 1c and the pillars 1b will not be fitted with each other. That is, if the pallet 1 is placed in a state as shown in FIG. 7, it is not possible to easily shift the position of the pallet 1 because the pallet 1 itself is a heavy object. You have to complain that you have to do it.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pallet capable of efficiently stacking materials when transported by truck or the like, thereby reducing transport costs. Is to do.

[0008]

[0009]

According to the pallet according to the first aspect of the present invention, since the interval between the columns in the longitudinal direction of the bottom is in units of length modules, even if pallets of different lengths are stacked, the columns and the fitting holes are not provided. Therefore, even if pallets of different lengths are used according to the size of the material, it is possible to stack pallets of different lengths on a carrier such as a truck without any trouble. . In addition, since the length of the bottom body in the longitudinal direction is an integral multiple of the approximate length module unit, it is possible to know in advance how many pallets of the length module unit can be loaded from the length of the front and back of the truck bed, Therefore, it is possible to easily understand how many pallets can be stacked before actually stacking.

Further , since the opening of the fitting hole has a large area and gradually decreases as it goes inward, and the bottom has a size substantially matching the shape of the top surface of the column, the pallets are connected to each other. When stacking, it is easy to position because the opening of the fitting hole is large, and after the fitting hole is fitted to the pillar, the upper pallet is positioned at the correct position along the internal shape of the fitting hole by its own weight. Stacked on.

[0011] Further , a pair of cylinders or a U-shaped section having a U-shaped cross section which is open on the lower surface side is provided at the center of the bottom body for inserting a fork of a forklift between the frames. The forklift makes it easy to transport the pallet because the reinforcing frame is provided along the longitudinal frame of the bottom body. The pallet can be transferred without any trouble even if a large number of pallets are loaded. Further, since the reinforcing frame is provided along the bottom frame, the pallet loading area is not reduced by the reinforcing frame.

[0012]

FIG. 1 is a view showing an embodiment of a pallet according to the present invention. In this figure, reference numeral 10 denotes a pallet. The pallet 10 is generally constituted by a bottom body 11 and a plurality of pairs of pillars 12 provided on the bottom body 11 upward.

The bottom body 11 is a rectangular frame-shaped frame body 13 made of steel.
And a steel mounting frame 14 provided vertically and horizontally inside the frame main body 13, in which stored items are mounted on the mounting frame 14. The frame main body 13 is formed to have a length in the longitudinal direction obtained by subtracting a predetermined length less than the length module unit M from an integer multiple of 2 or more of a predetermined length module unit M. Things. Here, the length module unit M corresponds to the basic length of a building material, for example, a panel.
mm), 910 mm, 1000 mm, and the like. The predetermined length less than the length module unit M is provided as a clearance so that when the pallets 10 are arranged in the longitudinal direction, they do not collide with each other, and is, for example, about 30 to 40 mm.

The pillars 12 are made of steel and are in the shape of a regular square pillar, and are arranged as pairs facing each other on frames 13a, 13a in the longitudinal direction of the frame body 13. In the example shown in FIG. Five pairs are provided. The distance between the center lines of the pillars 12 is the length module unit M described above in the longitudinal direction of the frame body 13. Moreover, the pillars 12a, 12 located on the outermost side in the longitudinal direction of the bottom body 11 are provided.
a and the distance L between the longitudinal edge of the bottom 11 and the bottom 1
1 are the same on both sides in the longitudinal direction. Then, a length twice as long as the distance L is a length obtained by subtracting the predetermined length less than the module unit M from the length module unit M. Therefore, with such a configuration, the pallet 10 has a length in the longitudinal direction of about 5M.

Further, a frame 13 provided with these pillars 12 is provided.
a, at a position where the column 12 is provided, a fitting leg 15 having a fitting hole to be fitted to an upper end portion of the column of the pallet when stacked on another pallet is provided integrally with the frame 13a. ing. The outer shape of the fitting leg 15 is a truncated square pyramid, and has a fitting hole 16 similar to the outer shape as shown in FIG. That is, the fitting hole 16 has a square shape having an opening larger than the top surface of the column 12 and a square shape gradually decreasing toward the inside thereof, and further has a bottom surface 16a thereof (the side opposite to the opening). Is formed in a size substantially matching the top surface shape of the column 12. The fitting leg 15 having such a fitting hole 16 is provided integrally with the bottom body 11 by being welded to the frame body 13 and the mounting frame 15 constituting the bottom body 11 and further to the column body 12. It has been done.

The height of the column body 12 is different from the height of the thickness (height) of the frame body 13, that is, the height from the bottom surface of the bottom body 11 to the upper end of the column body 12. The height obtained by subtracting the fitting height for fitting into the fitting hole of the pallet is 1/1, 3/4, of the predetermined height module unit m.
The value matches one of １ ／ and ４. Here, the height module unit m is, for example, a length obtained by subtracting a length required for loading / unloading from the height of the truck bed, specifically, 2100 mm or the like.

That is, if the pallet 10 is set to such a height, the pallet 10 having a height of 1/1 can be used as it is on a truck without stacking it, and the pallet 10 having a height of m can be used. Is the first 1 /
It can be adjusted to the same height as 1
By combining four of them, or two of them and one of the preceding ２, one can be adjusted to the same height as the 1/1. As described above, since the height module unit m is the optimum height for loading on a truck, that is, the height at which the height space of the cargo bed can be used most effectively, 3 m is set according to the size of the material to be stored. By appropriately selecting the type of pallet, more efficient loading becomes possible. The pallet 10 shown in FIG. 1 has a height of 1/4 of the height module unit m, and the column 12 shown by a two-dot chain line has a height of 1/2 of the height module unit m. Is shown.

FIGS. 3 and 4 show another embodiment of the pallet according to the present invention. The pallet 19 shown in FIG. 3 has a longitudinal length of about 3M. The pallet 20 has a longitudinal length of about 3M. The pallets 19 and 20 have basically the same configuration as the pallet 10 shown in FIG. 1 except for the length in the longitudinal direction.

The pallets 10, 19, 2 having such a configuration
In order to transport building materials, such as panels, by truck using 0, first, the length of the bottom body 11 in the longitudinal direction and the height of the column 12 are appropriately adjusted according to the size, shape, and amount of the materials. Select and select the corresponding pallet, and load the material on the pallet. And the length (depth) of the truck bed
What module calculated in advance or packed to (M), and by keeping also consider whether previously what stacking is possible for the height, loading good stacking how the loading efficiency as shown in FIG. 5 I do.

Here, when loading, since the forklift cylinders 17 are provided on each pallet, loading can be easily performed by using a forklift. At this time, the fitting leg 1
5 has a large area and the opening area gradually becomes smaller toward the inside, and the bottom part thereof has a size substantially matching the top surface shape of the column body 12. Are stacked, the opening of the fitting hole 16 is large, so that the positioning is easy.
After fitting, the upper pallet is stacked at the correct position along the internal shape of the fitting hole 16 by its own weight as shown in FIG.

In such pallets 10, 19 and 20, even if pallets of different lengths are stacked, the column 12
Since the positions of the fitting holes 16 correspond to the positions of the fitting holes 16, the fitting can be performed. Therefore, even if pallets having different lengths are used depending on the size of the material, the lengths of the pallets are different from each other on the truck bed. Different pallets can be stacked without any difficulty. Further, since the length of the bottom body 11 in the longitudinal direction is an integral multiple of the approximate length module unit, it is possible to know in advance how many pallets can be loaded in the length module unit from the length of the truck bed. It is easy to understand how many pallets can be loaded before actually loading them.

The height from the lower surface of the bottom 11 to the upper end of the column 12 is approximately 1/1, 3 /
Since it is any one of 4, 1/2, and 1/4, pallets having different heights can be used in a proper combination and used, so that the pallets can be stored in the truck bed. Further, since reinforcing frames 18 and 18 are provided on the cylindrical bodies 17 and 17 to reinforce the cylindrical bodies 17 and 17, respectively, even if a large amount of material is loaded on the pallet, there is no hindrance to the transfer, and furthermore, the reinforcing frames 18 and 18 are not damaged. 18 is provided along the frames 13b, 13b of the bottom body 11, so that the loading area of the pallet is
8 and 18 do not reduce the size.

In the above-described embodiment, a pair of cylindrical bodies 1 are used for inserting a fork of a forklift.
Although 7 and 17 are provided, instead of these, a U-shaped body having a U-shaped cross section that opens on the lower surface side may be provided.

[0025]

As described above, in the pallet according to the first aspect of the present invention, even when pallets having different lengths are stacked, the positions of the pillars and the fitting holes correspond to each other, so that the fitting can be performed. Therefore, even if pallets of different lengths are used depending on the size of the material, pallets of different lengths can be stacked on the truck bed without any trouble. In addition, since the length of the bottom body in the longitudinal direction is set to an integral multiple of the length module unit, it is possible to know in advance how many pallets can be loaded in the length module unit from the length of the truck bed. It is easy to know how many pallets can be loaded in a car. And since pallets of different lengths can be stacked up and down in this way, and since you can see how many pallets can be stacked before loading on trucks etc.,
The pallet of the present invention can be efficiently loaded on a carrier such as a truck, and therefore, the transportation cost can be reduced.

[0026]

Further , the fitting hole has a large opening area and a gradually decreasing area as it goes inside, and a bottom portion having a size substantially matching the top surface shape of the column. When the pallets are stacked, the positioning of the fitting hole is easy because the opening of the fitting hole is large, and after the fitting hole is fitted to the pillar, the upper pallet follows the internal shape of the fitting hole by its own weight. In the correct position.
Therefore, when the pallets are stacked by a forklift or the like, the time required for stacking can be shortened because the positioning is easy, and the workability of stacking can be greatly improved. Also form a mating hole
