Description

[Detailed Description of the Invention] The present invention relates to a pallet spacing material, and more particularly, to a pallet spacing material made of an aluminum alloy material.

Pallets are changing from wood to aluminum alloy and synthetic resin.

Pallets made of aluminum alloy or synthetic resin have the advantage that they are more durable than wooden pallets, and can be used more hygienically by cleaning.

Therefore, an object of the present invention is to provide a pallet girder material that has a simple structure that is easy to manufacture, and that facilitates installation and disassembly of deck boards, thereby increasing the popularity of aluminum alloy pallets.

According to this invention, it has a cross-sectional flange protruding from a side wall forming a hollow part, and a groove is provided between a horizontal part of the flange and a part of the wall forming the hollow part. A pallet girder material is provided that is integrally molded from a characteristic aluminum alloy extrusion mold material.

Furthermore, if tL<U, a groove having an opening is integrally molded inside the wall.

Embodiments of the present invention will be described with reference to the accompanying drawings.

The pallet beam member 1 has a hollow portion 2.

The hollow portion 2 is preferably rectangular, and a flange 4 having a cross-sectional shape is integrally provided to protrude from one end or both ends of one side wall 3 .

The horizontal portion 5 of the flange 4 is spaced apart from the wall 6 and preferably extends in the vicinity of the central portion of the wall 6 in a groove.

Further, on the inner wall surface of the wall 6, there is a reinforcing protrusion I extending in the longitudinal direction.
is provided to improve the strength of the girder material 1.

Although not particularly shown, on the inner wall surface of the opposing side wall 3,
Similarly, it is preferable to provide a protruding piece to increase the rigidity of the beam member 1.

The pallet girder 1 has an opening 8 in the wall 6 as shown in Fig. 2.
It is also possible to provide the groove 9 integrally.

This groove 9 serves to increase the strength of the girder 1, facilitate the installation of a pallet deck board by inserting a nut, etc. therein (i.e., prevent the nut from rotating), and also serves to It also functions to slide and hold a spacer (not shown) to provide a gap between the two.

The groove 10 between the horizontal part 5 of the flange 4 and the wall 6 is suitable for accommodating the end of the deck board 15.

As shown by the imaginary line, the end of the deck board 15 is inserted into the groove 10 formed by the flange 4 while sliding from one opening of the groove 10.
Since the horizontal portion 5 only extends to cover a portion of the wall 6, the sliding resistance is small and it is easy to maintain the dimensional accuracy of the groove 10.

Further, since it exhibits large bending resistance against stress acting on the end portion of the horizontal portion 5 of the flange 4, deformation is small.

As is clear from the above examples, the pallet girder material according to the present invention has a simple structure and can be easily manufactured by extrusion of aluminum material, so it can be provided in large quantities in small prints.

The post-manufacturing process involves cutting to predetermined dimensions and drilling holes for bolts as necessary, so processing is easy.

In addition, as shown in FIG. 3, the horizontal part 5 of the flange 4 and the wall 6
A protruding piece 11 facing each other is integrally provided, and the protruding piece 11
The spacer can also be slidably held via the spacer.

In this case as well, the effects described above can be easily achieved.

Furthermore, the reinforcing protrusion 7 may be provided with screw holes 16, as shown in FIG.

In this case, the deck board 15 is also provided with screw holes 17, and the deck board 15 and the girder member 1 are connected with the screws 19 as shown in the figure using the angle-shaped corner member 18.
Furthermore, the corner member 18 and the beam member 1 are connected using the screw holes 16 of the beam member 1.

In this example, the reinforcing protrusion 7 having screw holes has the effect of increasing the rigidity of the girder material having a hollow portion and also making it possible to fix the girder material 1 and the deck board 15.

The use of screw holes simplifies assembly and disassembly work since no nut tightening is required.

The etched boards arranged on both sides of the helmet are fixed to the girder member 1 using the corner members 18 as shown in the figure, but the center board between the etched boards is fixed to the girder member 1 through the screw hole of the center board. It can also be fixed to the girder 1 by screwing in screws through the wall surface.
