[0023]
As shown in FIG. 5, the center pallet member 23 includes a flat central connecting wall 80 formed at the center in the width direction, vertical walls 81 and 82 rising from both sides of the central connecting wall 80, and upper ends of the vertical walls 81 and 82. Overlap portions 83, 84 extending horizontally from the first and second side pallet members 21, 22, and hanging walls 85, 86 bent downward from the outer ends of the overlap portions 83, 84, have. The hanging walls 85 and 86 can function as inner wheel guide protrusions.
[0024]
The central connecting wall 80 is fixed to the upper surface of the reinforcing beam 24 by the fastening material 70. The standing walls 31 and 32 of the side pallet members 21 and 22, the fastening material 70, and the like are accommodated inside the overlap portions 83 and 84.
[0025]
As shown in FIG. 5, a slight gap G1 is secured between the inner surfaces of the overlap portions 83 and 84 and the upper ends of the upright walls 31 and 32 so that they do not contact each other. A slight gap G2 is also secured between the lower ends of the hanging walls 85 and 86 of the center pallet member 23 and the side pallet members 21 and 22 so that they do not contact each other.
[0026]
By forming such gaps G1 and G2, it is possible to prevent the generation of noise due to the contact between the side pallet members 21 and 22 and the center pallet member 23, and the standing wall 31 inside the overlap portions 83 and 84. , 32 and the hanging walls 85, 86 can be prevented from retaining rainwater or the like, and corrosion due to the inside of the center pallet member 23 being wet for a long time can be prevented.
[0027]
As shown in FIG. 5, a first adjustment margin S <b> 1 is formed between one vertical wall 81 and the hanging wall 85. The first adjustment margin S1 allows the standing wall 31 of the first side pallet member 21 to move in the horizontal direction in the space inside the overlap portion 83. A second adjustment margin S <b> 2 is formed between the other vertical wall 82 and the hanging wall 86. The second adjustment margin S2 allows the standing wall 32 of the second side pallet member 22 to move in the horizontal direction in the space inside the overlap portion 84.
[0028]
Next, a procedure for assembling the pallet 12 will be described.
The pair of left and right side pallet members 21 and 22 are placed on the reinforcing beam 24 so that the outer wheel guide protrusions 35 and 36 are located on both ends 24b and 24c side of the reinforcing beam 24, and the reinforcing material 70 is used as the reinforcing beam. It fixes to 24 flange parts 53 and 54. The side pallet members 21 and 22 are fixed by the fastening material 70 in the vicinity of the outer wheel guide protrusions 35 and 36 and in the vicinity of the standing walls 31 and 32.
[0029]
The center pallet member 23 is covered from above so that the standing walls 31 and 32 of the side pallet members 21 and 22 are covered by the overlap portions 83 and 84. The central connecting wall 80 is fixed to the flange portions 53 and 54 of the reinforcing beam 24 by the fastening material 70. The center pallet member 23 has a shape in which the central connection wall 80 is recessed downward from the overlap portions 83 and 84, so that the central connection wall 80 is reinforced according to the height of the vertical walls 81 and 82. It can be directly superimposed on the upper surface of the beam 24.
[0030]
Therefore, it is not necessary to use the spacer 6 as in the conventional example shown in FIG. 7, and the center pallet member 23 can be directly fixed to the reinforcing beam 24. In the center pallet member 23 of this embodiment, vertical walls 81 and 82 are formed between the central connecting wall 80 and the overlap portions 83 and 84, and hanging walls 85 and 86 are formed at the outer ends of the center pallet member 23. Since it is formed, high rigidity can be exhibited.
[0031]
Instead of forming the vertical walls 81, 82, the central connection wall 80 is made to be the same height as the overlap portions 83, 84, and the central connection wall 80 is used by using the same spacer 6 (shown in FIG. 7) as in the prior art. May be fixed to the reinforcing beam 24.
[0032]
Since the reinforcing beam 24 has a long central portion 24a in the longitudinal direction and both ends 24b and 24c are low, the side pallet members 21 and 22 fixed to the reinforcing beam 24 also have both ends 24b and 24c from the center pallet member 23 side. It becomes a downward slope toward. For this reason, the drainage property of the pallet 12 is good, and since water does not accumulate on the pallet 12, it is possible to improve the rust prevention quality and to prevent water from dripping from the upper pallet side toward the lower pallet.
[0033]
The center pallet member 23 covers the gap between the edge portions 21a and 22a inside the side pallet members 21 and 22. Therefore, the overall width of the pallet 12 is adjusted according to the overlapping width W (shown in FIG. 5) from the upright walls 31 and 32 of the side pallet members 21 and 22 to the hanging walls 85 and 86 of the center pallet member 23. Can do.
[0034]
For example, as shown by a solid line in FIG. 6, the overall width W3 of the pallet 12 can be increased by reducing the overlapping width W2 from the standing walls 31 and 32 to the hanging walls 85 and 86. On the other hand, as shown by a two-dot chain line in FIG. 6, the width W5 of the entire pallet 12 can be reduced by increasing the overlap width W4.
[0035]
Thus, in the range (adjustment margins S1 and S2) where the standing walls 31 and 32 of the side pallet members 21 and 22 and the hanging walls 85 and 86 or the vertical walls 81 and 82 of the center pallet member 23 do not interfere with each other. It is possible to obtain an arbitrary pallet width.
[0036]
For this reason, a pallet 12 having a desired width can be constructed simply by preparing one type of side pallet members 21 and 22 and one type of center pallet member 23. This makes it possible to simplify the inventory management of the materials and greatly contribute to the cost reduction of the pallet 12.
[0037]
Further, the side pallet members 21 and 22 and the center pallet member 23 can be fixed by the fastening material 70 to the flange portions 53 and 54 of the reinforcing beam 24 having a hat-shaped cross section whose upper surface side is open, and welding work is unnecessary. For this reason, when the side pallet members 21, 22 and the center pallet member 23 and the reinforcing beam 24 are made of a surface treatment material such as plating, there is no damage to the surface treatment due to welding. It is possible to provide a high-quality and inexpensive pallet without deteriorating the beauty.
[0038]
