In order to stack the transport packaging boxes B in the assembled state, as shown in FIG. 11, the upper transport packaging boxes B are placed on the four corner members 19 of the lower transport packaging box B. May be placed. At this time, the side walls 20 ₁ ... formed in the corner member 19 ... of the support plate 20 ..., it is possible to stabilize the stacking state to prevent the leg members 9 ... slip.

When the transport packing box B is in the assembled state, the U-shaped locking member 22 of the corner member 19 engages with the upper girder 24 of the side frame 3 from above as shown in FIG. Therefore, there is no danger that the corner member 19 will slide in the direction of arrow c along the upper spar 12 of the gate formwork 2 due to vibration or the like.

Further, even if the swing in the direction of the arrow b in FIG. 5 to 12 around the upper girder corner member 19 by vibration or the like, swinging range of the corner member 19 and the solid line position of FIG. 5 by the stopper projection 11 ₂ Since the corner member 19 is restricted between the position of the dashed line, the corner member 19 is prevented from largely swinging. Thus, when the transport packing box B receives a strong impact, the corner member 19 swings largely to generate noise, and the swing angle exceeds 90 °, and the corner member 19 cannot return to the original position. Be avoided.

Further, when an upward load is applied to the side frame 3, the corner member 19 is pushed upward by the hook member 23 provided on the upper beam 24 of the side frame 3. Upper spar 1 of portal form 2 which is the axis
Since it has reached the vicinity of the vertical plane including the axis 2, the side frame 3
The upward load acting on the corner member 19
Does not swing upward.

Next, a procedure for folding the transport packing box B will be described.

First, each corner member 1 of one portal form 2
9 is swung to a position abutting the stopper projection 11 ₂ (dashed line position in FIG. 5), the lower end of the locking member 22 provided on the lower surface of the corner member 19 exceeds the upper edge of the upper girder 24 of the side frame 3 For this reason, as shown in FIG.
The corner member 19 can be retracted from above the upper girder 24 of the side frame 3 while sliding along the upper girder 12 in the direction of arrow d. Therefore, by retracting the two corner members 19, 19 located at both ends of the side frame 3 as described above, the side frame 3 can be pulled out and removed. One side frame 3 thus removed
Is mounted on the upper surface of the bottom plate 1 as shown in FIG. The other side frame 3 is also removed in the same procedure, and is placed on the upper surface of the bottom plate 1.

Subsequently, one of the portal frames 2 is pulled up, and the lock members 14, 14 of the columns 11, 11 are supported.
After detaching from the notches 10 ₂ and 10 _{2 at} 0 and 10, the portal form 2 is turned down by 90 ° so as to overlap the upper surface of the bottom plate 1 as shown in FIG. Similarly, the other portal form 2
Is also turned down by 90 ° so as to overlap the upper surface of the one gate form 2. Thus, the transport packaging box B is compactly folded as shown in FIG. At this time, one portal form 2 folded first is on the lower side and the other portal form 2 folded later is on the upper side.
0 ... are absorbed by the upper and lower positions of the guide pins 13 in the long holes 10 ₁ .

Further, the folded transport packaging box B is provided by placing the leg members 9 of the upper transport packaging box B on the upper ends of the support members 10 of the lower transport packaging box B. FIG.
As shown in FIG. 2, they can be stacked and compactly transported or stored.

Although the embodiment of the present invention has been described in detail, the present invention is not limited to the above embodiment, and various design changes can be made.

[0031] For example, the swing range of the corner member 19 is restricted by the stopper projection 11 _{and second} strut 11 in the embodiment, the locking member 2 projecting from the lower surface of the corner members 19
2 is set to the minimum size that can pass above the upper girder 24 of the side frame 3, but if the swingable range is 90 ° or less, the corner member 19 swings upward due to vibration or the like. In this case, it can be surely returned to the original position.

[0032]

According to the first aspect of the present invention, the locking member of the corner member restricts the upward movement of the side frame, so that the side frame can be reliably prevented from coming off. In addition, when disassembling the transport packaging box, the side frame can be removed only by swinging and sliding the corner member so that the locking member is detached from the upper end of the side frame. Also,
Since the swingable range of the corner member is limited within 90 ° above the position where the upward movement of the side frame is regulated by the swing regulating means, even if the corner member swings upward due to vibration or the like, the corner member is not moved. The member can be reliably returned to the original position.

According to the second aspect of the present invention,
By causing the hook member to face the lower surface of the corner member near the vertical plane including the axis of the upper girder, even if an upward load is applied to the side frame and the hook member tries to push up the corner member, the corner member is raised. Swing around the girder is prevented.
