  As shown in FIG. 7 (b), the transport pallet 1 places items on the floor material 2 and lifts the forklift pawls 51 and 52 under the floor material 2 when the forklift lifts the intermediate floor beam. Lift along 5 and 6.

  When an article is placed on the flooring 2 and lifted by a forklift, the load of the article acts in a direction to push down both ends of the flooring 2, but the flooring 2 is leveled by the tension acting on the diagonal members 41 to 44. Can be supported. At this time, the tension acting on the diagonal members 41 to 44 acts in the direction of compressing the intermediate column members 11 to 14 downward in the axial direction via the upper skirt members 31 and 32. Thereby, the top beam members 21 and 22 and the intermediate column members 11 to 14 do not come off during use without being fastened with bolts. Thereby, even if it does not fasten the upper sash materials 31 and 32 and the top beam materials 21 and 22 with a volt | bolt, a nut, etc., each member does not remove | deviate. Since no fastening member is used in this way, assembly and disassembly can be further facilitated.

  The transport pallet according to one embodiment of the present invention has been described above, but the transport pallet according to the present invention is not limited to the above-described embodiment.

  For example, the corrugated plate-like steel panel is exemplified as the floor material, but the present invention is not limited to this, and the floor material may be a plate material, or a plurality of rod-shaped plate materials may be arranged to constitute the floor. Further, the cross-sectional shape of each member is not limited to the above embodiment. Moreover, the intermediate floor beam should just be arrange | positioned at the vertical direction in the at least 2 place which separated the intermediate part of the horizontal side edge of a flooring.

  In addition, although an example in which an oblique member is attached to the upper siding material is illustrated, the oblique member may be attached to both ends of the ceiling beam material. It is better to attach the ceiling beam material to the intermediate column material.

  Further, for example, when the transport pallet 1 is placed at a stepped portion, the base is distorted, and the upper skirt members 31 and 32 are pushed up by the diagonal members 41 to 44. As a result, the engagement of the members is released. There is a possibility that. In order to prevent this, the slant members 41 to 44 among the protrusions 11a to 14a of the intermediate pillar members 11 to 14, the top beam members 21 and 22 and the upper sill members 31 and 32 are attached, and are attached to overlap. The side member may be provided with a retaining portion that prevents the disengagement of each member.

  For example, as shown in FIG. 8, the protrusion 11 a of the intermediate column member 11 forms a retaining portion 55 that protrudes in the outer diameter direction at the base end portion, decreases in diameter toward the top portion, and retains in the upper skirt material 31. A locking hole 56 that is locked to the portion 55 may be formed. In this embodiment, the locking holes 56 are large enough to allow the tops of the projections 11a of the intermediate column member 11 to be inserted, and are radially cut to allow expansion / contraction of the holes. Then, as shown in FIG. 9, the top beam members 21 and 22 are attached to the intermediate column member 11, and the locking holes 56 of the upper skirt members 31 and 32 are inserted therethrough. The locking hole 56 is enlarged in diameter when inserted into the protrusion 11 a of the intermediate column member 11, and is fitted and locked to the retaining portion 55. In this way, in the engagement structure between each of the intermediate column members 11 to 14 and the upper edge members 31 and 32, it is preferable to provide the retaining portion 55 in the same manner. As a result, when the transport pallet 1 is placed at a level difference, the upper sash members 31 and 32 are not lifted from the intermediate column members 11 to 14, and the engagement of each member is surely released. Can be prevented.

  In addition, it is not limited to the said structure, As shown in FIG. 10, the retaining claw 57 which protruded in the outer-diameter direction is formed in the base end part of protrusion 11a-14a of the intermediate | middle pillar material 11-14, and the upper sash material 31, When the 32 is mounted, the holes of the upper skirt members 31 and 32 may be locked to the claws 53.

  Moreover, although the intermediate pillar materials 11 to 14, the top beam materials 21 and 22, and the upper stile materials 31 and 32 are illustrated as being detachable from each other, as shown in FIG. The beam members 21 and 22 may be integrally configured, and the upper skirt members 31 and 32 having the diagonal members 41 to 44 attached thereto may be attached thereto. Also, as shown in FIG. 12, the intermediate column members 11 to 14 and the upper skirt members 31 and 32 are integrally formed, and the top beam members 21 and 22 to which the diagonal members 41 to 44 are attached are attached. May be. Thereby, the number of assembling points can be reduced, and assembling and dismantling are facilitated.

Moreover, as shown in FIG. 13, the ceiling beam members 61 and 62 may be constructed diagonally with respect to the intermediate column members 11-14. Thereby, it can prevent that the intermediate column materials 11-14 shift to a diagonal. In this case, the ceiling beams 61 and 62 are preferably joined at the intersections with the rivets 63 so that they can be assembled and disassembled integrally.

  Further, in order to improve the stability when stacking the transportation pallets 1, as shown in FIG. 14, the intermediate column members (11, 13), (12, 14) facing in the vertical direction are slightly moved inward. You may tilt. Thereby, when the transportation pallets 1 are stacked, the transportation pallet 1 can be prevented from shaking.

  The connection structure for connecting the intermediate column members 11 to 14, the top beam members 21 and 22, and the upper sill members 31 and 32 in the axial direction is not limited to the above-described one. For example, as shown in FIG. 15, holes 11 b to 14 b are formed at the tops of the intermediate column members 11 to 14, and the top holes 11 b to 14 b at the tops of the intermediate column members 11 to 14 are attached to the ends of the ceiling beam members 21 and 22. The projections 21b and 22b projecting downward may be provided, the projections 21c and 22c projecting upward may be provided above, and the upper skirt members 31 and 32 may be connected to the projections. In addition, it is not limited to this, A various connection structure is employable.
