Thereby improving the bonding strength. In this case, a second long bolt coupling groove 231 through which the second long bolt 60 penetrates may be formed in the coupling reinforcing portion 230 of the expansion panel 20.

The expansion panel 20 may be manufactured in one mold so that one expansion panel 20 may be used in both the horizontal direction and the vertical direction.

To this end, the expansion panel coupling portion 210 and the second projection receiving portion 211 according to an embodiment of the present invention may be formed symmetrically in the expansion panel 20 based on the stopper insertion groove 220. . At this time, the coupling reinforcing portion 230 is formed only at any one of the upper side or the lower side, and is formed at a position that can achieve the up and down symmetry. The first long bolt groove 205 may be formed in a vertically symmetrical shape by penetrating the top and bottom of the expansion panel 20.

That is, the above-described expansion panel 20 functions as the expansion panel 20 in the vertical direction when the horizontal expansion panel 20 is vertically inverted. At this time, the expansion panel coupling portion 210 and the second protrusion receiving portion 211 of the expansion panel 20 coupled to the horizontal direction of the main body 10, when coupled to the longitudinal direction of the main body 10 of the longitudinal direction It can be coupled to the stopper seating portion 130 and the second protrusion 133.

On the other hand, the coupling reinforcing portion 230 coupled to the lower coupling groove 123 in the horizontal direction is coupled to the upper coupling groove 121 in the vertical direction. The first long bolt 70 may be coupled to the first long bolt groove 205 which is formed in the expansion panel 20 symmetrically.

Therefore, the expansion panel 20 coupled to the horizontal direction of the main body 10 may be inverted up and down to be coupled to the longitudinal direction of the main body 10. Accordingly, since only one mold for manufacturing the expansion panel 20 needs to be manufactured, the manufacturing cost of the pallet can be reduced.

When the expansion panel 20 is coupled to all sides of the main body 10, the corner connecting portion 30 may be coupled to the end of the expansion panel 20. The corner connector 30 may be coupled to both ends of the expansion panel 20. The corner connecting portion 30 connects the expansion panel 20 in the horizontal direction and the expansion panel 20 in the vertical direction so that the main body 10 and the expansion panel 20 form the upper surface of the pallet for loading the cargo. .

Corner connecting portion 30 and the end of the expansion panel 20 may be combined in various forms. In one embodiment of the present invention, the corner connecting portion 30 is formed by protruding the T-shaped projection 310, the T-shaped groove 240 for receiving the T-shaped projection 310 at the end of the expansion panel 20 is recessed. It is formed.

In addition, in order to improve the coupling strength of the corner connecting portion 30 and the end of the expansion panel 20 according to the embodiment, the corner connecting portion 30 may be coupled to the end of the expansion panel 20 and the pin 80.

In this case, the first pin hole 320 to which the pin 80 is coupled may pass through the corner connector 30. The first pin hole 320 may be formed in one of a horizontal direction and a vertical direction. The first pin hole 320 may be formed at both sides of the T-shaped protrusion 310.

A second pin hole 250 corresponding to the first pin hole 320 may be formed at an end of the expansion panel 20. The second pin holes 250 may be formed at both sides of the T-shaped groove 240.

Accordingly, by placing the stopper 110 in the connection position of the stopper 110, the expansion panel 20 can be coupled to the main body 10 so that the loading area can be varied, so that a separate pallet can be manufactured according to the size of the cargo. There is no need to reduce the logistics cost.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
