[Structure of Connecting Plate] As shown in FIGS. 2 and 3, in the first embodiment, two connecting plates 31a and 31b are used.
Kinds of connecting plates 31a, 31b are used. Both connecting plates 31
a and 31b are lower end surfaces 31a1 and 31a extending in substantially the same direction (front-back direction) as the lower side surface of the flat parting material 11 for the seat portion.
b1 and front end faces 31a2 and 31b2 which are inclined rearward at an inclination angle substantially the same as the inclination angle θ of the flat dividing material 21 for the back portion with respect to the lower end faces 31a1 and 31b1. Further, a total of two connecting plates 31a located at the left and right ends (outermost) of the flat part 11 for seats or the flat part 21 for backs,
Each of them has a modified pentagonal plate shape in which two vertexes of a triangle are cut off. On the other hand, flat split material for seat 1
One or a total of 45 connecting plates 31b located in the center (inside) of the back splitting material 21 each have a modified pentagonal plate shape in which the apex portion of one rectangular corner is cut off. That is, the connecting plate 31b completely overlaps the front side and the central portion of the connecting plate 31a. The rear side portion of the connecting plate 31a projects rearward from the rear end of the connecting plate 31b. As a result, between the rear end surface 31b3 of the connecting plate 31b and the upper end surface 21a1 of the back connecting portion 21a of the back flat splitting material 21,
A triangular space is formed.

The seat 10 may have a configuration other than the above as long as a portion of a predetermined length on the rear end side of the seat splitting member 11 can be secured as the seat connecting portion 11a. Similarly, the back portion 20 may have a configuration other than the above as long as a portion of a predetermined length on the lower end side of the back splitting material 21 can be secured as the back portion connecting portion 21a. That is, the seat connecting portion 11a and the back connecting portion 21a are portions for fixing the connecting plates 31a and 31b,
The position and the length of the connecting plates 31a and 31b are determined depending on the shape and the fixing mode of the connecting plates. Therefore, for example, the plate member 12 of the seat portion 10 and the plate member 22 of the back portion 20 are the same as the connecting plate 31.
As long as it does not interfere with a and 31b and does not interfere with the connection of the seat connecting portion 11a and the back connecting portion 21a by the connecting plates 31a and 31b, the sheet is fixed to the rear end portion of the seat portion 10 and the lower end portion of the back portion 20. You can also Also, the plate member 2 of the back 20

Here, in a state where the back portion 20 is inclined rearward with respect to the seat portion 10 within an angle range of about 3 to 10 degrees, the seat portion 10 and the back portion 20 are connected by the connecting plates 31a and 31b. It is preferred that they be immovably fixed to each other.
If the inclination angle of the back portion 20 is smaller than 3 degrees, the stone material may fall forward when the vertically stacked stone materials are supported by the back portion 20 in a state of being leaned. On the other hand, when the inclination angle of the back portion 20 is larger than 10 degrees, a load applied from the leaning stone material to the back portion 20 is large, and the back portion 20 cannot sufficiently support the load of the stone material depending on the number of loaded stone materials (total weight). There is a possibility. Further, according to the present invention, in the state where the back portion 20 is inclined rearward with respect to the seat portion 10 at an angle in the range of about 3 degrees to 7 degrees, the seat portion 10 is connected by the connecting plates 31a and 31b.
Further, it is more preferable that the back portions 20 are immovably fixed to each other (even more preferably 3 to 5 degrees). Back 2
When the inclination angle of 0 is an angle in the range of about 3 degrees to 5 degrees,
The stones can be supported on the back 20 in a stable and leaning state, and even when the stones are fully loaded in the normal use state,
The back portion 20 can sufficiently support the load of the stone material.

[Reinforcing plate when inserting fork] The connecting plate 3
The rear portions 1a and 31b project rearward from the rear side surface of the back splitting material 21. Furthermore, the connecting plates 31a, 3
1b, the rear end surface 31b3 of the connecting plate 31b other than the connecting plates 31a at the left and right ends of the seat portion 10 has a connecting plate 3 at the left and right ends.
It is formed so as to extend in a substantially vertical direction at a position in front of the rear end surface of 1a. Then, a reinforcing plate 35 as a long plate-shaped reinforcing wood material is disposed between the connecting plates 31a at the left and right ends, and its front side surface is brought into contact with the rear end surface 31b3 of the central connecting plate 31b. In this state, nailing is performed from the side surface side thereafter, so that the connection plate 31b is fixed to the rear side. The reinforcing plate 35 is further connected to the connecting plate 31a with its left and right end faces abutting the inner surfaces of the connecting plates 31a at the left and right ends.
It is also preferable to fix it to the inner side of the connecting plate 31a by nailing it from the outer surface side.

The width of the connecting plate 31b is such that a triangular space for attaching the reinforcing plate 35 can be formed between the rear end surface 31b3 of the connecting plate 31 and the upper side surface 11a1 of the seat connecting portion 11a. It is preferable to make it as large as possible. The larger the width of the connecting plate 31b, the connecting plate 31
In particular, the fixing area of the seat connecting portion 11a due to b increases,
In addition, since the area of the connecting plate 31b itself is also increased, the connecting strength between the seat flat material 11 and the back flat material 21 can be increased. Therefore, the rear end surface 31b3 of the connecting plate 31b
Should be located as rearward as possible. The shapes of the connecting plates 31a and 31b are as shown in FIG. 1 as long as they can connect the seat connecting portion 11a and the back connecting portion 21a.
Other shapes than those shown in FIG.

[Protruding portion of plate material] Here, the plate materials 12 and 22 of the seat portion 10 and the back portion 20 have a space (left and right dimension) between the flat portion split material 11 for the seat portion and the flat split material 21 for the back portion at both left and right ends. Has a greater length. Then, the plate members 12 and 22 are seated so that the left and right ends thereof protrude to the left and right by a predetermined dimension (for example, 5 cm) from the seat splitting members 11 and the back flatting members 21 at the left and right ends. It is fixed to the flat split material 11 and the back flat split material 21.

[Manufacturing Method] Next, an example of a method of manufacturing the stone wooden pallet according to the first embodiment configured as described above will be described.

In order to manufacture a wooden pallet for stones, for example, first, a flat dividing material 11 for seats arranged at the same left and right positions.
A pair of left and right connecting plates 3 corresponding to the flat split material 21 for the back
It connects by 1a and 31b. That is, the flat-split material for seat 11
In the state in which the back splitting member 21 is inclined rearward at a predetermined angle θ, the seat connecting portion 11a and the back connecting portion 21 are provided.
A is sandwiched between the connecting plates 31a and 31b and fixed to each other.
At this time, the lower end surfaces 31a1, 3 of the connecting plates 31a, 31b
Aligning the front side surface of the back connecting portion 21a of the back splitting member 21 with the front end surfaces 31a2, 31b2 of the connecting plates 31a, 31b with 1ba matched with the lower side surface of the seat connecting portion 11a. Thus, the back splitting member 21 can be automatically aligned with the seat splitting member 11 at a predetermined inclination angle θ. Then, in this state, the pair of left and right connecting plates 31a and 31b are fixed to the back connecting portion 21a by nailing or the like, whereby the back flat dividing material 21 is predetermined with respect to the seat flat dividing material 11. Can be connected and fixed at an inclination angle θ. As a result, the back split material 21 can be easily positioned with respect to the seat split material 11, and the workability can be improved.

In this way, after manufacturing the connected body of the three flat-split members 11 for the seat and the flat-split member 21 for the back, these are arranged in parallel on the left and right at equal intervals, and the plate member 12 is placed on the flat-split member 11 for the seat. The plate material 22 is attached to the back splitting material 21 by nailing or the like. Then, the reinforcing plate 35 is fixed to the lower end side of the rear end surface 31b3 of the connecting plate 31b. At this time, the reinforcing plate 35
The corner portion between the lower end surface and the front side surface of the seat portion should be brought into contact with the corner portion between the upper side surface 11a1 of the seat connecting portion 11a and the rear end surface 31b3 of the connecting plate 31b. Thus, the reinforcing plate 35 can be easily positioned. Then, in this state, the reinforcing plate 35 is connected to the connecting plate 31a,
It can be easily fixed to 31b by nailing or the like. As a result, the reinforcing plate 35 is fixed to the rear end of the back splitting material 21, and the back splitting material 21 is connected and reinforced.

[How to Use] Next, a method of using the wooden pallet for stone according to the first embodiment configured as described above will be described.

When not using stones, a large number of wooden pallets for stones are stacked vertically and stored in a storage location such as a warehouse, or at a site such as a stone factory where stones are loaded. Be transferred to. Therefore, as shown in FIG. 5, the wooden pallet for stones is vertically stacked without the reinforcing plate 35 being fixed, and when the stones are stacked, the reinforcing plate 3 is used.
It is preferable that 5 is fixed later. FIG. 5 is a front view showing a case where a reinforcing plate is retrofitted in the stone pallet 0 according to the first embodiment. That is, when the stone wooden pallets are stacked and conveyed, the reinforcing plate 35 is not fixed to the stone wooden pallets but is conveyed separately in a separated state and fixed when the stone S is used at the loading site. In this way, when the empty wooden pallets for stone are stacked vertically and stored and / or transferred, the reinforcing plate 35
It is possible to stack a larger number of stone pallets for stone materials in multiple stages without increasing the number of the pallets and to increase the number of stacks. When retrofitting the reinforcing plate 35, the reinforcing plate 3
Compared with the case where there is 5, it is possible to stack twice as many stone pallets for stone.

On the other hand, when using a wooden pallet for stone,
As shown in FIG. 2, the stone materials S are vertically stacked and loaded on each stone pallet for stone materials. That is, the stone materials S having a rectangular plate shape or the like are sequentially stacked and loaded in the front-rear direction of the seat portion 10 while being leaned toward the back portion 20. After a predetermined number of stone materials S are vertically stacked on the stone wooden pallet, the stone materials S are fastened and fixed on the seat portion 10 by fastening bands B such as PP bands, and the stone materials S move from the seat portion 10 during transportation. Do not drop it. Then, in this state, the pair of left and right forks of the forklift are inserted into the pair of left and right recessed spaces extending in the front-rear direction formed between the rear part of the back portion 20 and between the flat split members 11 for seats, and the seat portion 10 is inserted by the forks.
The wood pallet for stone is moved up and down through the plate 12 of
Unload it on a truck bed. At this time, the upper surface of the base end side of the fork is the reinforcing plate 3 of the wooden pallet for stone material.
It contacts the lower end surface of 5. Therefore, when the reinforcing plate 35 is not provided, the stone material S is attached to the plate material 12 of the seat portion 10 via the fork.
The load of is directly applied, but in the present embodiment,
The load of the stone S is shared by the reinforcing plate 35. As a result, the plate material 1 of the seat portion 10 is conveyed during transportation by a forklift.
2 can be effectively prevented. Further, the lateral deflection of the back portion 20 when a stress is applied to the back portion 20 in the left-right direction can be effectively prevented by the reinforcing plate 35.

[Operation and Effect] Next, the operation and effect of the wooden pallet for stone according to the first embodiment configured as described above will be described.

Since the wooden pallet for stones is entirely made of a wooden material, it is inexpensive and there is no risk of damaging or damaging the stone S unlike a steel pallet. Furthermore, the wooden pallet for stones has a pair of left and right connecting plates 3.
The seat connecting portion 1a and 31b support the seat connecting portion 11a of the seat dividing material 11 and the back connecting portion 21a of the back dividing material 21 in a state of being sandwiched from the left and right sides.
The 1a and the back connecting portion 21a can be supported by a surface and connected. Therefore, the connecting area between the seat portion 10 and the back portion 20 increases. In particular, the connecting strength in the front-rear direction (inclining direction of the back portion 20) of the stone wooden pallet is dramatically increased. Therefore, the wooden pallet for stones can sufficiently secure the strength (maximum supporting load) with respect to the load on the front side of the back portion 20 and on the rear side (which is the inclination direction of the back portion). As a result, the inclination angle θ of the back portion 20 with respect to the seat portion 10
Even if is increased, the back portion 20 does not fall backward due to the backward load of the stone S. In the present embodiment, the back portion 20 can be tilted up to about 10 degrees with respect to the seat portion 10 in a normally assumed use state, although it depends on the number and weight of the stone materials to be loaded. Accordingly, the stone materials S vertically stacked on the seat portion 10 can be leaned against the back portion 20 with a large inclination angle θ and supported, and the stone materials S can be transported or transported in a more stable state. Further, in the stone wooden pallet according to the present embodiment, the back portion 20 does not easily fall forward even when a front load is applied to the back portion 20 by the stone material S or the like.

According to the results of experiments conducted by the inventors, it has been confirmed that the wooden pallet for stone according to the present embodiment has a drastically increased strength (maximum supporting load) against a front load. For example, in the case of the wooden pallet for stones of the type shown in FIG. 1, the load resistance of the back portion 20 against the leaning stones was as follows when measured under the following conditions.

[0041] Dimension = W800mm * L900mm * H800mm Total load weight = 1200kg Inclination angle of back 20 = about 5 degrees

Maximum rear supporting load capacity (rear load capacity) = about 200 kg This is a sufficient value even in consideration of normal use conditions (maximum number of loaded stone materials, maximum load, etc.).

Maximum front support load capacity (load capacity to the front) = about 240 kg This is a value which is more than sufficient even in consideration of normal use conditions.

In addition, by connecting the back part 20 to the seat part 10 in a plane manner, the strength of connecting the back part 20 to the seat part 10 is increased not only in the front-rear direction but also in the left-right direction of the wooden pallet for stones. be able to. Therefore, when the stone material S is loaded on the seat 10, even if stress is applied in the left-right direction, it is possible to prevent the back 20 from laterally swinging, and prevent buckling of the back 20 with respect to the seat 10. can do.

Further, the connecting plates 31a, 31b can be made of inexpensive plywood such as structural plywood, and the manufacturing cost of the wooden pallet for stone can be further reduced.

Here, the plate member 1 of the seat portion 10 and the back portion 20
When the right and left ends of 2, 22 are flush with the flat part 11 for seat and the flat part 21 for back, the flat part 1 for seat is 1
When the plate members 12 and 22 are nailed to the 1 and the back split member 21, there is a possibility that the left and right ends of the plate members 12 and 22 are cracked by the nailing. However, in the present embodiment, the protruding portions at the left and right ends of the plate members 12 and 22 absorb the stress in the cracking direction (width direction of the plate members 12 and 22) due to nailing, so that the plate members 12 and 22 are cracked. It can be effectively prevented.

[Diagonal Driving of Nail] When the pair of left and right connecting plates 31a and 31b are nailed to the seat connecting portion 11a and the back connecting portion 21a, usually, the seat connecting portion 11a is used.
And, nails are linearly driven at regular intervals along the length direction of the back connecting portion 21a. However, it is also possible to strike the nails on the connecting plates 31a and 31b in a zigzag shape while shifting the positions alternately in the width direction along the vertical direction of the seat connecting portion 11a and the back connecting portion 21a. In this way, the connecting plate 31
The load applied in the surface direction of a, 31b can be evenly distributed in the surface direction by the zigzag nails and can be borne, and the seat portion 10 and the back portion 20 by the connecting plates 31a, 31b.
The connection strength of can be further increased. Further, in this case, nailing can be performed so that one side and the other side of the pair of left and right connecting plates 31a and 31b are symmetrical in zigzag directions (diagonal nailing). For example, one of the connecting plates 31a, 31
In b, (connecting part for seat 11a and connecting part for back 21a
Zigzag four nails in the order of left, right, left, and right (when viewed from one side in the thickness direction of the), and the other connecting plates 31a and 31b (the connecting portion for the seat portion 11a and the connecting portion for the back portion). The four nails are struck in a zigzag manner in the order of right, left, right, and left (when viewed from one side in the thickness direction of the part 21a). In this way, the pair of left and right connecting plates 31
The load applied in the plane direction of a and 31b can be evenly distributed in the plane direction by the diagonally nailed nails and can be borne.
It is possible to further increase the connecting strength between the seat portion 10 and the back portion 20 by the connecting plates 31a and 31b.

[Use of Wide Plate] In the present embodiment, a wide plate (back width plate) is used as each of the plates 12 and 22. In this case, the plate material 12 composed of the back width plate,
It is preferable to fix 22 to the flat part 11 for seats and the flat part 21 for backs by nailing three nails 22 arranged at substantially constant intervals in the vertical direction. This can effectively prevent the plate members 12 and 22 from twisting in the front-rear direction or the vertical direction. In addition, the use of the back width plate increases the strength of the entire wooden pallet for stone material.

[Second Embodiment: Block Material for Fixing Reinforcing Plate] FIG. 6 is a perspective view showing a main part of a wooden pallet for stone according to a second embodiment of the present invention.

The stone wooden pallet according to the second embodiment is the same as the stone wooden pallet according to the first embodiment.
It further comprises a block-shaped wood material for fixing the reinforcing plate 35. Other configurations are similar to those of the first embodiment.
Specifically, as shown in FIG. 6, in the second embodiment, the embedded block material 41 as a block-shaped wood material having a corresponding width is inserted into the gap between the pair of connecting plates 31a and 31b. , Fixed by nailing. At this time, the embedded block member 41 has rear end surfaces connected to the connecting plates 31a and 31b.
It is arranged so as to be substantially flush with the rear end face. The embedded block material 41 can be fixed by nailing from the outside of the connecting plates 31a and 31b, or by nailing the flat dividing material 11 for the seat portion. Then, in the second embodiment,
The reinforcing plate 35 is arranged on the rear end faces of the connecting plates 31a and 31b, and is fixed to the rear end face of the embedded block material 41 by nailing. At this time, the reinforcing plate 35 is connected to the connecting plate 3
It is also possible to fix it to the rear end faces of 1a and 31b by nailing.

In the second embodiment, with the front side surface of the reinforcing plate 35 in contact with the rear end surfaces of the connecting plates 31a and 31b, the reinforcing plate 35 is simply nailed to the embedded block member 41. Can be fixed. As a result, the reinforcing plate 35 exerts the same operation and effect as in the first embodiment.

[Third Embodiment: Notch Recess for Band Storage] FIG. 7 is a perspective view showing a wooden pallet for stone according to a third embodiment of the present invention as viewed from the back side.

The stone wooden pallet according to the third embodiment is the same as the stone wooden pallet according to the first embodiment.
A cutout recess 12a for accommodating the fastening band B is further provided. Other configurations are similar to those of the first embodiment. Specifically, as shown in FIG. 7, in the third embodiment, a pair of left and right cutout recesses 12a is formed by cutting out at the front edge of the frontmost plate member 12 of the seat portion 10. The notch recesses 12a are respectively formed at substantially central positions in the left-right direction between the left and right seat splitting members 11 and the central seat splitting member 11. Further, each notch recess 12a has a substantially rectangular planar shape.

Here, when the cutout recess 12a is not provided at the front edge of the plate member 12 on the frontmost side of the seat portion 10, the stone material S is loaded on the seat portion 10 and fastened and fixed on the seat portion 10 by the fastening band. When doing so, the front end of the frontmost plate member may be cracked by the fastening pressure of the fastening band B. However, in the third embodiment, when the stone S is fastened, the fastening band B is housed in the notch recess 12a, and the notch recess 12a.
It abuts the plate member 12 inside. Therefore, the fastening pressure of the fastening band B is evenly absorbed by the peripheral portion of the cutout recess 12 a of the plate member 12. As a result, it is possible to effectively prevent the frontmost plate member 12 from cracking.

[Fourth Embodiment: Wire Receiving Groove] FIG. 8 is a side view showing an essential part of a wooden pallet for stone according to a fourth embodiment of the present invention.

In the case where the stone material is conveyed by the stone material wooden pallet, in a predetermined case, a wire is slid on the seat portion 10 of the stone material wooden pallet and is transferred to a high place of a building on a construction site by a crane. There is. In this case, the wire is slid in the left-right direction of the seat portion 10. Therefore, in the stone wooden pallet according to the fourth embodiment, in the stone wooden pallet according to the first embodiment, the wires W are respectively housed at the front and rear positions on the lower surface of the flat part 11 for the seat portion. The accommodation groove 11b is formed. Other configurations are similar to those of the first embodiment. Specifically, as shown in FIG. 8, at the predetermined positions on the front side and the rear side of each seat portion flat dividing member 11, the accommodation grooves 11b extend in the width direction of the seat portion flat dividing member 11, respectively. Has been formed. Therefore, the three front accommodation grooves 11b and the three rear accommodation grooves 11b of the flat-split material 11 for the seat portion are continuous in a straight line in the left-right direction of the seat portion 10, respectively.

In the wooden pallet for stone of the fourth embodiment,
The wires W are provided on the front side and the rear side of the seat portion 10, respectively.
Can be housed and arranged along the housing groove 11b of the flat-split material 11 for a seat, and can be slid. This makes it possible to effectively prevent cracking of the lower end of the flat part 11 for the seat, which is the part where the wire W abuts. Also, when placing a wooden pallet for stones on the ground or floor such as a transfer place,
The sled wire W does not get in the way. Therefore,
After placing the wooden pallet for stones on the ground or floor such as a transfer place, the slid wire Y can be easily pulled out from the seat 10 without lifting the wooden pallet for stones. In addition, instead of the accommodation groove 11b, the flat member 1 for the seat portion is used.
The same effect can be obtained by forming a through hole penetrating 1 in the width direction.

[Embodiment 5: Left and right caulking prevention structure] FIG. 9 is a front view showing a main part of a stone wooden pallet according to a fifth embodiment of the present invention.

The stone wooden pallet according to the fifth embodiment is the same as the stone wooden pallet according to the first embodiment.
The thickness (vertical dimension) of the flat-split material 11 for the seat portion is set so that the central one is smaller than the left and right ones by a predetermined dimension X. Other configurations are similar to those of the first embodiment. More specifically, as shown in FIG. 9, in the fifth embodiment, of the three seat section splitting members 11 arranged at equal intervals in the left-right direction of the seat section 10, the center section for the seat section is split. The thickness of the material 11C is made slightly smaller than the thickness of the left and right seat division flat members 11S by a predetermined dimension X. Then, in a normal state where the stone material S is not loaded on the seat portion 10, the left and right seat portion flat-splitting materials 11S contact the ground G, and the lower side surface of the central seat portion flat-splitting material 11C moves upward from the ground G. I am trying to locate it. On the other hand, stone S
In a loaded state in which the seats 10 are loaded by the load of the stone S.
The left and right centers of the plate member 12 are elastically curved downward so that the left and right seat portion flat-split materials 11S and the central seat portion flat-split material 11C are all in contact with the ground G.

Here, when all (three in the example shown) flattening members 11 have the same thickness, the ground G is not flat, or all flats for seats located at the left and right and in the center are flat. When the lower surface of the split member 111 is not flush, either one of the left and right seat flat split members 11 and the central seat flat split member 11 come into contact with the ground G and the left and right seats are Division material for parts 11
There is a possibility that the other of the above floats from the ground G. In this case, the seat portion 10 is liable to the left and right like a jumbled bar with the central flat portion material 11 for the seat portion as a fulcrum, causing creaking or wobbling, or when the stone material S is loaded on the seat portion 10 due to the load. The seat 10 may buckle. However, in the fifth embodiment, in a normal state in which the stone S is not loaded on the seat portion 10, the lower surface of the central flat parting material 11C for the seat portion is located above the ground G, so that
Only the left and right seat splitting members 11S contact the ground G. As a result, the seat portion 10 does not squeeze to the left and right like the sword barbecue, with the central split member 11C for the seat portion as a fulcrum. Therefore, when the seat 10 is squeaky or wobbles, or when the stone S is loaded on the seat 10, the load causes the seat 10 to move.
Does not buckle. In addition, the stone S on the seat 10
In a loaded state in which the seats 10 are loaded by the load of the stone S.
The left and right centers of the seat are elastically curved downward, and the left and right seat portion flat-split members 11S and the center seat flat-split material 11C all come into contact with the ground. Therefore, all the flat dividing materials 11S, 1 for seats
The seat portion 10 is supported by 1C, and the load of the stone material S can be stably and reliably borne.

The thickness of the central flat member 11C for the seat,
The difference (dimension X) from the thickness of the left and right flat split members 11S is
It can be of any size, but is typically from 1 mm to 5
The range of mm is preferable. If it is less than 1 mm, it may not be possible to secure a sufficient dimensional difference between the thickness of the central flat parting material 11C for the seat and the thickness of the flat parting material 11S for the left and right seats due to dimensional errors and dimensional accuracy during manufacturing. is there. On the other hand, 5m
If it exceeds m, the strength of the flat split material for seat 11C at the center may decrease. However, the center splitting material for seat 11C
And, it is possible to secure the difference in the thickness of the flat split material 11S for the left and right seats,
In addition, it is of course possible to use another dimension X as long as the strength of the central flat member 11C for the seat portion can be secured.

By the way, at least three flat dividing members 11 for the seat may be arranged at equal intervals in the lateral direction of the seat 10, and four or more flat dividing members 11 may be arranged. In either case,
As described above, the thickness of the central flat material 11 for the seat portion may be made slightly smaller than the thickness of the horizontal flat material 11 for the seat portions.

[Sixth Embodiment: Corner Block] FIG.

Furthermore, the wooden pallet for stones according to the sixth embodiment is provided with the flat split materials 1 for the left and right seats.
Similar corner blocks 51 are fixed to a pair of left and right inner corner portions formed between the inner side of the front end portion of No. 1 and the frontmost plate member 12, respectively. The corner block 51 of the inner corner portion may be omitted.

Here, when the stone material S is loaded on the seat portion 10, the stone material S is placed on either of the left and right protruding portions of the plate material 12.
If the load is applied unevenly, the seat portion 10 may buckle left and right. However, in the sixth embodiment, the plate material 12
The corner blocks 51 existing in the outer corner portions on the lower surface side of the protruding portions at the left and right ends contact the ground and reliably support the load of the stone material S applied to the protruding portions at the left and right ends of the plate member 12. As a result, buckling of the seat portion 10 can be effectively prevented. Furthermore, the corner block 51 of the inner corner
However, similarly, the load of the stone material S applied to the protruding portions at the left and right ends of the plate material 12 is surely supported by coming into contact with the ground. As a result, buckling of the seat portion 10 can be prevented more effectively.

Also, the back connecting portion can be supported while being supported in a planar manner. Therefore, the connecting area between the seat portion and the back portion is increased, and in particular, the connecting strength in the front-rear direction (inclining direction of the back portion) of the stone wooden pallet is dramatically increased. Therefore, it is possible to dramatically increase the strength with respect to the load to the rear, which is the direction of inclination of the back. As a result, even if the angle of inclination of the back portion with respect to the seat portion is increased, the back portion does not fall due to the load of the stone material. As a result, the stone materials vertically stacked on the seat portion can be leaned against the back portion with a large inclination angle and supported, and the stone materials can be transported or transported in a more stable state.

In addition, by connecting the back portion to the seat portion in a planar manner, the strength of connecting the back portion to the seat portion can be increased not only in the front-rear direction but also in the left-right direction of the stone pallet for stone material. Therefore, when a stone material is loaded on the seat portion, even if a stress is applied in the left-right direction, the back portion can be prevented from laterally swinging, and buckling of the back portion with respect to the seat portion can be reduced.
