The wall panel generally has a rectangular outer shape having a long side and a short side. The plurality of wall panels may be stacked on a bed of a truck, for example, in a so-called flat stacking manner in which long sides and short sides are horizontally stacked. For example, the wall material used for the curtain wall construction method has a large outer shape, and has a short side of 1.75 m or more. In order to stack the large-sized wall materials in a flat manner, the width of the truck bed must be wider than the short side of the wall materials. However, if the width of the road leading to the construction site is narrow, there is a problem that it is difficult for a large truck with a large cargo bed to pass through. Therefore, as shown in Patent Document 1, a small truck having a narrow bed width is used as a transport vehicle and is loaded on the small truck in a state where the wall material is erected in the vertical direction.

On the other hand, considering the height limit of the Road Traffic Act, if the long side of the wall material is 3 m or more, it should be avoided to load it on a small truck with the long side of the wall material along the vertical direction. Therefore, with the long side of the wall material in the horizontal direction and the short side of the wall material in the upright position in the vertical direction, the wall material should be fixed to a carrier such as a gantry and loaded on a small truck. Is possible. The wall material is attached to the frame of the house with the long sides of the wall extending in the vertical direction. Therefore, the wall material fixed to the carrier is rotated 90 degrees at the construction site and lifted by the crane. Such work of rotating the wall material requires a work space at the construction site and a long working time because the transportation device to which the wall material is fixed is unloaded from the small truck to the ground. It was

Hereinafter, a method of using the carrying device 10 will be described.
For example, the transportation device 10 is placed on a floor or the like in a factory where the wall material 15 is manufactured, or in a transshipment site between the factory and the construction site. The connecting member 14 has been removed and each support member 13 is in the second position. Then, each wall member 15 to be transported is attached to each support member 13 in the second position. For example, the wall member 15 is suspended by a crane with the long side L extending in the up-down direction 7, the short side S is attached to the first arm 31 of the support member 13, and the long side L is the support member 13. Attached to the second arm 32 of the. Then, the upper short side S of the wall member 15 attached to the support member 13 is moved forward by the crane in the front-rear direction 8, so that the support member 13 at the second position rotates toward the first position. The wall member 15 also moves from the state in which the long side L extends in the up-down direction 7 to the state in which the short side S extends in the up-down direction 7.

The support member 13 that has reached the first position supports the wall member 15 with the long side L of the wall member 15 extending along the front-rear direction 8 and the short side S extending along the up-down direction 7. When the support member 13 is in the first position, the support bar 23 of the base 11 contacts the long side L of the wall member 15 to support the wall member L. That is, the support member 13 in the first position and the support bar 23 together support the wall member 15.

The wall member 15 is attached to each supporting member 13, and the connecting member 14 is attached to the rear end of the base 11 with each supporting member 13 in the first position. As a result, each support member 13 is held at the first position. The carrying device 10 in this state is placed on the bed of the truck 6, as shown in FIG. The carrying device 10 is appropriately fixed to the bed of the truck 6.

When the truck 6 leaves the factory or the transshipment area and reaches the construction site, the connecting member 14 is detached from the base 11 and each supporting member 13. Then, when the short side S of the wall member 15 and the support member 13 are in the first position, the short side S on the front side is lifted by the crane, and the short side S is moved rearward, so that FIG. As shown in FIG. 6, the support member 13 at the first position rotates toward the second position, and the wall member 15 also has the short side S extending in the front-rear direction 8 from the state where the long side L extends in the front-rear direction 8. Rotate toward the following state.

As shown in FIG. 7, the support member 13 that has reached the second position has the long side L of the wall member 15 along the up-down direction 7 and the short side S of the wall member 15 along the front-rear direction 8 and the wall.

In such construction site work, the transportation device 10 may or may not be unloaded from the bed of the truck 6.

[Operation and effect of this embodiment]
According to the carrying device 10 of the present embodiment, the wall member 15 is supported by the support member 13 at the first position in a laterally standing posture in which the long side L is along the front-rear direction 8. By rotating the support member 13 from the first position to the second position, the wall material 15 is rotated from the horizontal direction to the vertical direction without the wall material 15 being lowered from the transport device 10. Therefore, at the construction site, it is easy to rotate the wall material 15 supported by the carrying device 10. Moreover, since the wall member 15 is oriented vertically by the support member 13 in the second position, the wall member 15 can be easily lifted by a crane.

Moreover, since the support member 13 supports the long side L and the short side S of the wall member 15, respectively, when the support member 13 and the wall member 15 are rotated, the support member 13 and the wall member 15 are stable. ..

Further, the connecting member 14 prevents the support member 13 from rotating from the first position when the wall material 15 is transported by the truck 6 on which the transportation device 10 is loaded.

Further, when the support member 13 is in the first position, the support bar 23 of the base 11 supports the wall member 15, so that the wall member 15 is stable.

Moreover, since the plurality of support members 13 are rotatably supported by the base 11 at positions where their respective axial directions are aligned on the virtual straight line A, the wall material 15 can be efficiently transported. Moreover, in the carrying device 10, it is easy to sequentially rotate the plurality of wall members 15.

[Modification]
In the above embodiment, the base 11 has the bottom portion 21 and the side portions 22, but the shape and the structure of the skeleton of the base 11 are at least the rotation of the support member 13 and the wall member 15 and the wall member 15 during transportation. The frame is not limited to the bottom portion 21 and the side portions 22 disclosed in the above-described embodiment as long as the frame can support.

Further, in the above-described embodiment, the support member 13 has the first arm 31 and the second arm 32, but the support member 13 does not have the second arm 32 and has a rod-like shape having only the first arm 31. It may be one.

Further, the support member 13 at the second position may be in a state where the short side S of the wall member 15 intersects the up-down direction 7, and it is not always necessary for the short side S of the wall member 15 to extend along the front-rear direction 8, that is, the wall. It is not necessary to rotate the member 15 to a position where the member 15 is completely oriented vertically.

Further, in the carrying device 10, instead of the connecting member 14, a known lock mechanism for holding the support member 13 at the first position may be provided.
