In addition, the upper pallet 1c is arranged to be fixed to the upper side of the vertical pallet 1b, and the upper pallet 1c may be arranged in the same position as the bottom pallet 1a or alternately arranged at different positions. have.

As such, the pallet 1 is manufactured by combining the bottom pallet 1a, the vertical pallet 1b, and the upper pallet 1c.

Here, the pipes used in the pallet (1) may be used in a variety of pipes, such as square, circle, polygon, etc., it is preferable to use a pipe of the square shape to obtain a safe holding force.

In addition, a reinforcing bar (p) generally used inside the corners of the bottom pallet (1a) may be additionally installed and used, and the reinforcing bar (p) is generally installed on the pallet (1), and thus detailed description thereof will be omitted. Do it.

Then, the "b" shaped frame 2 is arranged on the left and right sides 2a, 2b, 2c, and 2d before and after the top of the pallet 1, and then, by using a welding method or the like. Install.

Here, the method of joining, cutting, or bending the pallet 1, the frame 2, and the respective iron plate 10, the fixing part 20, the vertical part 30, and the like may be combined, cut, or bent. The method is generally used, such as welding, and the detailed description thereof will be omitted.

Then, a part of the frame 2 is bent to one side to the frame 2 positioned at the front 2a and the rear 2b so as to form the front protrusion 21 and the rear protrusion 22 inward of the frame 2. do.

Here, the front protrusions 21 and the rear protrusions 22 may be formed to face each other, and may be installed diagonally to each other.

In addition, the front protrusions 21 and the rear protrusions 22 may be installed at both sides of the frame 2, but only one side may be installed so that the user can easily disassemble and assemble the base frame 24 to the frame 2. Good to do.

In addition, on both sides of the frame 2 located in the left and right side directions 2c and 2d, a part of the frame 2 is bent into the frame 2 to form a protruding bent portion 23.

In addition, the front and rear projections 21 and 22 formed on the frame 2 are formed to be parallel to the ground, and the bent portion 23 is formed to be inclined at an angle with the ground.

Here, the reason why the bent portion 23 is formed to be inclined at an arbitrary angle with the ground is that when assembling and separating the base frame 24 from the frame 2, the base frame 24 is easily assembled from the frame 2. , To isolate.

In addition, as shown in FIG. 7, when the bent portion 23 is bent in the frame 2, the bent portion 23 may be bent in parallel with the ground or bend in the vertical direction with the ground.

On the other hand, after the horizontal frame 31 is installed on the ground, the vertical bar 32 is coupled to the horizontal frame 31.

Here, the horizontal frame 31 is the same as the frame 2 of the front, rear (2a, 2b) and the frame (2) of the left, right side direction (2c, 2d) or the front, rear (2a, 2b) or left One of the right side directions 2c and 2d is set to be slightly shorter.

This means that when all the horizontal frames 31 have the same interval as the frame 2, one side of the horizontal frame 31 is larger than the interval of the frame 31 so that the horizontal frame 31 is not properly coupled. Therefore, in order to prevent this, one of the front and rear directions 2a and 2b or the left and right side directions 2c and 2d is slightly shortened.

In addition, when fixing the vertical bar 32 to the horizontal frame 31, it is preferable to make the lower part of the vertical bar 32 coupled to the frame 2 slightly narrower than the upper coupled to the horizontal frame 31. .

This is because when the width of the vertical bar 32 positioned in the direction of the horizontal frame 31 is slightly widened, after assembling each device, when the object is loaded on the pallet 1, the upper side becomes a wide shape. This is because it can be easily loaded.

Here, when fixing the vertical bar 32 to the horizontal frame 31, either in the direction of the outer or inner side of the horizontal frame 31 of the "b" shape may be installed the same.

In addition, the vertical bar 32 may be formed with a compression unit 35, the compression unit 35 may be formed only at any one of the upper or lower portion of the vertical bar 32, or may be formed at both the upper and lower portions. have.

In addition, the compression part 35 may be formed by cutting a part of the vertical part 32 or compressing it using a device such as a press (not shown).

In addition, a plurality of auxiliary rods 32a are installed at a lower portion of the vertical bar 32 in the horizontal direction of the vertical bar 32 to fix the same.

At this time, when fixing the auxiliary rod (32a) to the lower portion of the vertical bar 32, after forming the compression unit 35 in the direction of the frame 2 toward the lower portion of the vertical bar 32, the compression unit (35) to be coupled to the auxiliary rod (32a).

In addition, when the auxiliary rod 32a is coupled to the vertical bar 32, the center portion of the auxiliary rod 32a is directed toward the outside of the vertical bar 32, and both sides of the auxiliary rod 32a are vertical bars. It is good to point to the inside of (32).

This is because the auxiliary bar 32a is staggeredly coupled to the vertical bar 32 while increasing the supporting force of the vertical bar 32 to support the force transmitted to the vertical bar 32 by staggering the vertical bar 32 to the force of the object. It is to prevent the separation from the horizontal frame 31 easily.

In addition, the auxiliary rod 32a is installed in the frame 2 direction to closely contact with the frame 2. The reason why the vertical bar 32 directly adheres to the frame 2 is an object loaded on the pallet 1. The force is transmitted to the vertical bar 32 and the force is transmitted from the vertical bar 32 to the frame 2, when the vertical bar 32 is in direct contact with the frame 2, the vertical bar 32 Is locally in contact with the frame 2 and the force is transmitted to the frame 2 only in part, so that the auxiliary rod 32a coupled to the vertical bar 32 is directed toward the frame 2. This is to disperse the force transmitted by the object so that the entirety 32a is intimately attached to the entire frame 2.

On the other hand, when the vertical bar 32 is coupled to the horizontal frame 31, it is good to bend the center portion of the vertical bar 32 slightly bent.

This is because the vertical bar 32 is bent to the outside of the pallet 1 while the object loaded on the pallet 1 transmits the force to the outside of the pallet 1, which prevents the vertical bar 32 from bending outward. It is to.

Here, when the vertical bar 32 and the horizontal frame 31 are combined, a plurality of the vertical bars 32 and the rear frame 2a and 2b and the left and right side surfaces 2c and 2d may be manufactured. .

Then, the vertical bar 32 installed in the front and rear directions 2a and 2b of the frame 2 and the vertical bar installed in the left and right side directions 2c and 2d of the horizontal frame 31 or the frame 2. The base frame 24 is fixed to the vertical bar 32 and the horizontal frame 31 in any one of the 32 and the horizontal frame 31.

In addition, the horizontal bar (34) is coupled to the vertical bar 32, the horizontal bar 34 is to allow the vertical bar 32 is coupled to the upper direction coupled to the horizontal frame (31).

In addition, compression sides 35 may be formed on both sides of the horizontal auxiliary bar 34, and both sides of the horizontal auxiliary bar 34 may be positioned inwardly of the base frame 24, and the center portion may be a vertical bar. Fix it so as to face the outside of (32).

This causes the center portion and both sides of the horizontal subsidiary bar 34 to be bent to be bent, so that the vertical bar 32 is moved by the force transmitted from the vertical bar 32 to the outside of the pallet 1 in the horizontal frame 31. This is to prevent easy separation.

In addition, a first rotating part 41 is formed in the horizontal frame 31 provided in the frame 2 in the front and rear directions 2a and 2b, and the frame 2 in the left and right side directions 2c and 2d. The horizontal frame 31 to be installed to install the hinge 42 is coupled to the ring 42 and the ring 42.

In addition, the first rotating part 41 and the hinge part 43 are generally used in a packaging carrying box, and thus detailed description thereof will be omitted.

Here, the base frame 24 is formed in a "b" shape, the front, the back frame (21, 22) is formed in close contact with the direction of the frame 2 of the front, rear (2a, 2b) ( The cutting portion 25 corresponding to the front and rear protrusions 21 and 22 is formed in the 24, and the bent portion is formed in the base frame 24 in close contact with the frame 2 in the left and right side directions 2c and 2d. 23 to form a bending groove 26 corresponding to.

After that, each corner of the frame 2 is installed in the vertical direction of the base frame 24 of the "b" shape.

Here, when fixing the lower part of the base frame 24 to the frame 2 as described above, the direction of the front and rear projections 21, 22 formed in the front, rear (2a, 2b) of the frame (2) Thus, the cutout portions 25 are installed to correspond to each other, and the bent grooves 26 are installed in the bent portions 23 formed in the left and right side directions 2c and 2d of the frame 2.

In addition, the cutting portion 25 is formed with a horizontal cutting surface 25a and a vertical cutting surface 25b, the horizontal cutting surface 25a to be formed to be spaced apart from the front, rear projections (21, 22).

Then, the inclined cutting surface 25c connected to the vertical cutting surface 25b is formed at the cutting portion 25.

Here, the inclined cutting surface 25c is inclined θ of 5 to 45 ° with respect to the vertical cutting surface 25b.

The reason for forming the inclined cutting surface 25c as described above is to reduce the wear of the front, rear projections 21 and 22 and the inclined cutting surface 25c while reducing the weight of the base frame 24, the frame (2) The front projection 21 or the rear projection 22 and the cutting portion 25 of the base frame 24 to easily correspond, and to facilitate the movement of the base frame 24.

As shown in a and b of FIG. 8, the front and rear protrusions 21 and 22 and the bent portions 23 are formed in the frame 2, and the cut portions 25 and the bent portions are formed on the base frame 24. By forming the 26 to correspond to the front and rear projections 21 and 22 and the bent portion 23, the cut portion 25 and the bent groove 26, the base frame 24 is in close contact with the frame 2 Even if the user positions the base frame 24 in the frame 2 and the distance from the base frame 24 increases, the base frame 24 will not fall.

In detail, when the user and the operator couple the cutting portion 25 of the base frame 24 to the front protrusion 21 or the rear protrusion 22 of the frame 2 correspondingly, the horizontal cutting surface of the cutting portion 25 25a is positioned in parallel with the front projection 21 or the rear projection 22.

At this time, when the user and the operator moves the upper portion of the base frame 24 in the outward direction of the frame 2, the horizontal cutting surface 25a formed on the cutting portion 25 while the base frame 24 is moved, Since the base frame 24 is fixed inclined while being in close contact with the front protrusion 21 or the rear protrusion 22 so that the base frame 24 does not fall while being separated from the frame 2 by its own weight, the user and the operator 2) It is possible to fix the base frame 24 and to do other work, and one user and operator can simultaneously, before and after the frame 2, in the left and right side direction (2a, 2b, 2c, 2d) (24) can be installed and fixed.

In addition, the bent portion 23 formed in the frame 2 and the bent groove 26 formed in the base frame 24 also serve to fix the frame 2 and the base frame 24 as described above. (2) and the base frame 24 can be fixed in two.
