By inserting the locking tongue pieces 18 on both sides into the locking holes 19 of the bottom piece 11 and locking the reinforcing pieces 17, a tubular body portion having a triangular cross section is formed on both sides, and the tubular body portions are bent at the folds 12 and bent on both sides. The tops 15 of the tubular portions having a triangular cross section are aligned with each other, and the staples 10 are fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corrugated cardboard reinforcing cylinder used as a core material of a corrugated cardboard pallet or a packing material to be housed in a packaging box.

[0002]

[Prior art]

 Conventionally, as this type of corrugated fiberboard reinforcement, a corrugated fiberboard cylinder containing a core material has been often used, but it has been time-consuming to form the corrugated fiberboard and has insufficient rigidity.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention provides a strong tubular reinforcing body that can be formed by a simple bending operation.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is used as a core material of a corrugated cardboard pallet, a packing material to be housed in a packaging box, and the like, and the body pieces are connected to each other through folds on both sides of the bottom piece, and the body pieces are folded. The top pieces are connected through the eyes, the reinforcing pieces for bracing are connected to the top pieces through the folds, the locking tongue pieces are projected on the reinforcement pieces, and the bottom pieces are connected. The folds do not have locking holes.

[0005]

[Action]

 By bending at each fold and inserting and locking the locking tongues of the respective reinforcing pieces into the locking holes, cylindrical sections with a triangular cross section are formed on both sides of the bottom piece. By combining them, each celestial piece becomes a single rectangular cylinder that is flush with each other, and the reinforcing pieces face each other in a cross-section C-shape and are in a bracing state.

[0006]

Embodiment An illustrated embodiment of the present invention will be described below. The corrugated board pallet shown in FIG. 1 is formed by arranging a plurality of reinforcing cylinders 1 of this example in parallel, interposing a corrugated board reinforcing material 2 between them, and vertically adhering corrugated board sheets 3.

The reinforcing tubular body 1 has the expanded configuration shown in FIG. 2, in which body pieces 13 are continuously provided on both sides of the bottom piece 11 via folds 12, and each of the body pieces 13 has fold pieces 14 on top. In addition to connecting 15 in series, reinforcing pieces 17 for bracing are connected to each top piece 15 via folds 16, locking tongue pieces 18 are projected to each reinforcing piece 17, and each bottom piece is connected. The fold portion 12 is provided with a locking hole 19 not provided.

The width of each top piece 15 is half the width of the bottom piece 11, and the width of the reinforcing piece 17 is the length reaching the fold 12 in the assembled state. The projecting width of the locking tongue piece 18 is such a length that it can be inserted and locked in the locking hole 19, and the locking hole 19 is transparently provided at a position facing the locking tongue piece 18.

From this unfolded state, bend at each fold, and insert the locking tongue pieces 18 on both sides into the locking holes 19 of the bottom piece 11 to lock the reinforcing piece 17 as shown in FIG. A tubular body portion having a triangular cross section is formed on both sides with a fold 12, and the tubular body portions having a triangular cross section on both sides are aligned with the top piece 15 and fastened with staples 10 as shown in FIG. It can be assembled.

As a result, each top piece 15 becomes a quadrangular cylindrical body that is flush with each other, and the respective reinforcement pieces 17 are arranged so as to face each other in a C-shaped cross section. That is, the reinforcement piece 17 is arranged in a bracing state with the fold 12 by the engagement of the engagement tongue piece 18 in the engagement hole 19.

Therefore, the reinforcing pieces 17 are reinforced by the bracing arrangement of the reinforcing pieces 17 to form a strong reinforcing cylinder 1, and a solid corrugated board pallet is formed.

Although the present example is configured as described above, the present invention is not limited to this. For example, regardless of its size or shape, the width of the top piece may be extended to form a trapezoidal reinforcing cylinder as shown in FIG. Further, the number of locking tongues protruding from the reinforcing piece is also appropriate. Further, there is no limitation on the joining means for the tubular portions having triangular cross sections on both sides that are formed during bending, and if the corrugated sheet or the like is adhered to each top piece, the triangular cross sections on both sides are prepared in advance. It is not necessary to join the tubular parts.

The use of the reinforcing cylinder of the present invention is arbitrary, and the reinforcing cylinder may be used as a packing material, a partition material, or the like to be housed in the packaging box. When used as the core material of a corrugated board pallet, the number and arrangement state are not limited.

[0014]

[Effect of device]

 According to the present invention, since the reinforcing pieces are arranged to face each other in a bracing state, the effect of strengthening is great, and since the reinforcing pieces are stably arranged by the locking tongue pieces, the bending is easy and the work can be performed smoothly. There are also advantages.
