(how to use)
Next, referring to FIG. 1 to FIG. 6, the method of using the pallet stacking jig 1 when transporting and storing building materials, specifically, the pallet between the lower pallet 2 and the upper pallet 4 is used. A procedure for stacking the lower pallet 2 and the upper pallet 4 in the vertical direction through the stacking jig 1 will be described.
When transporting or storing plate-shaped building materials such as wall panels, a pallet stacking jig 1 is interposed between the lower pallet 2 and the upper pallet 4, and the lower pallet 2 and the upper pallet 4 Are stacked in the vertical direction, first, the pallet stacking jig 1 arranged above the lower pallet 2 is attached to the lower pallet 2.

Specifically, after placing the lower pallet 2 on which the plate-shaped building material 10 is placed on the lower frame body 6 with the lower support column 8 facing upward, The pallet stacking jig 1 is moved above the lower pallet 2 (see FIG. 1). The state where the lower pallet 2 is placed on the ground surface or the like with the lower column 8 facing upward means that the lower pallet 2 is attached to each lower column 8 of the lower frame 6. The state which mounted on the ground surface etc. in the state which protruded upwards from the side surface is shown. The building material 10, the lower pallet 2, and the pallet stacking jig 1 are moved using, for example, a forklift.
After the pallet stacking jig 1 is moved above the lower pallet 2, the distance between the two first rod members 24 (the first rod member 24D and the first rod member 24U) is adjusted.

Specifically, the first rod-shaped member 24D is replaced with the upper ends of the respective column receiving members 30 provided in the first rod-shaped member 24D and the three lower columns 8 on one side (the lower column 8 illustrated in FIG. 1). However, it arrange | positions in the position which opposes an up-down direction seeing from the axial direction (left-right direction of FIG. 1) of 1st rod-shaped member 24D (refer FIG. 1).
Further, the first rod-shaped member 24U is similarly configured of each column receiving member 30 provided in the first rod-shaped member 24U and the remaining three lower columns 8 on one side (lower columns not shown in FIG. 1). An upper end part is arrange | positioned in the position which opposes in an up-down direction seeing from the axial direction of the 1st rod-shaped member 24U.

At this time, in a state where the positioning pin 50 inserted into the second positioning hole 52 and inserted through the second insertion hole 66 is pulled out from the second insertion hole 66, the first rod-shaped member 24U is moved in the axial direction of the second rod-shaped member 26. (See FIG. 6). And the positioning pin 50 inserted in the 2nd insertion hole 66 is inserted in the 2nd positioning hole 52 in the state which has arrange | positioned each support | pillar receiving member 30 with which the 1st rod-shaped member 24U is equipped to said position (refer FIG. 6). .
As described above, after the two first rod-shaped members 24 are arranged, each column receiving member 30 is displaced in the axial direction of the first rod-shaped member 24, and the upper end portion of the lower column 8 and the vertical direction (See FIG. 1).

At this time, the positioning inserted through the column receiving side insertion hole 48 in a state where the column receiving side insertion hole 48 is aligned with the first positioning hole 46 formed at a position facing the upper end of the lower column 8 in the vertical direction. The pin 50 is inserted into the first positioning hole 46 (see FIG. 6). As a result, the column support member 30 disposed at a position facing the upper end portion of the lower column 8 in the vertical direction is fixed to the first rod-shaped member 24 and is displaced in the axial direction of the first rod-shaped member 24. The displacement of the member 30 with respect to the first rod-shaped member 24 is suppressed.
In addition, the operation | work which adjusts the distance between the two 1st rod-shaped members 24 and the operation | work which displaces each support | pillar receiving member 30 to the axial direction of the 1st rod-shaped member 24 are the position of the lower support | pillar 8 previously, for example. If it is known, it may be performed before the pallet stacking jig 1 is moved above the lower pallet 2.

  The distance between the two first rod-shaped members 24 is adjusted, and further, each column receiving member 30 is arranged at a position facing the upper end of the lower column 8 in the vertical direction. The pallet stacking jig 1 moved upward is lowered (see FIG. 1). Thereby, the upper end portion of the lower column 8 is inserted into the lower opening 38 of the lower fitting portion 36 formed in each column receiving member 30 (see FIG. 3), and the lower column 8 has the lower side. The pallet stacking jig 1 placed on the lower pallet 2 is fitted to the lower pallet 2 by fitting the fitting portion 36 (see FIG. 1).

Further, the area of the upper surface of the lower opening 38 is equal to or larger than the area of the upper end surface of the lower column 8. Therefore, when the lower support column 8 is inserted into the lower opening 38, the lower support column 8 is inserted into the opening that is larger than the area of the upper end surface of the lower support column 8. There is no need to finely position the upper end surface of the lower support column 8 with respect to the side opening 38.

Further, as described above, the shape of the lower opening 38 of the lower fitting portion 36 is formed such that the opening area increases from the upper side to the lower side. For this reason, as the upper end portion of the lower support column 8 is inserted into the lower opening portion 38 (as the pallet stacking jig 1 is lowered), the upper end surface of the lower support column 8 is brought into contact with the inner wall surface of the lower opening portion 38.

Specifically, the upper end of the second rod-shaped member 26L is the upper end of the fixed column support member 32F included in the second rod-shaped member 26L and the upper column 18 shown on the left side in FIG. The parts are arranged at positions facing each other in the vertical direction. At this time, the second rod-shaped member 26L is moved in the axial direction of the first rod-shaped member 24 so that the upper convex portion 42 of the upper fitting portion 40 formed on the fixed column support member 32F is opened in the upper column leg 22. (See FIG. 1).
Further, the second rod-shaped member 26R is also shown on the right side in FIG. 1 among the fixed column support member 32F provided on the second rod-shaped member 26R and the two upper columns 18 on one side, similarly to the second rod-shaped member 26L. The upper end part with the upper support | pillar 18 is arrange | positioned in the position which opposes an up-down direction. At this time, the second rod-shaped member 26R is moved in the axial direction of the first rod-shaped member 24 so that the upper convex portion 42 of the upper fitting portion 40 formed on the fixed column support member 32F is opened in the upper column leg 22. (See FIG. 1).

Here, when each second rod-shaped member 26 is moved in the axial direction of the first rod-shaped member 24, the positioning pin 50 inserted into the first positioning hole 46 and inserted into the first insertion hole 62 is used as the first insertion hole. In the state of being pulled out from 62, each second rod-shaped member 26 is displaced in the axial direction of the first rod-shaped member 24 (see FIG. 6). And the positioning pin 50 inserted in the 1st insertion hole 62 is inserted in the 1st positioning hole 46 in the state which has arrange | positioned each 2nd rod-shaped member 26 to said position (refer FIG. 6).

That is, a second attaching / detaching means for detachably connecting the second rod-shaped member 26 and the connecting member 28 may be formed by the positioning pin 50 and the second insertion hole 66. In this case, a female screw that is screwed with a male screw formed on the outer peripheral surface of the positioning pin 50 is formed on the inner peripheral surface of the second insertion hole 66, and the female screw and the male screw formed on the positioning pin 50 are screwed together. It is preferable that the tip of the positioning pin 50 inserted through the second insertion hole 66 is pressed against the second rod-shaped member 26.
