Description

  The present invention relates to a pallet girder, and particularly to a girder that is lightweight and has high strength without causing environmental damage.

  A cargo handling pallet is generally manufactured using wood board or plywood, but it is easily perishable due to moisture absorption, and it is disposed of by incineration when it cannot be used.

  However, timber is used by cutting and drying trees that take decades to grow and drying them, processing them into predetermined shapes and dimensions, or laminating and bonding wooden thin plates. The use of this material requires the logging of a large amount of trees, leading to the destruction of the global environment.

  On the other hand, thin bamboo boards made of bamboo are arranged in a bowl shape, and a plurality of board boards are laminated and bonded to produce a bamboo board. The bamboo board is used as a material for the pallet. A bamboo pallet has been proposed (Patent Document 1), but in order to make the surface on which the load is loaded have sufficient strength, it is necessary to stack the slats in multiple layers, which makes it heavy.

  On the other hand, a lightweight bamboo board has been proposed in which vertically divided bamboo is used as a structural member, which is vertically crossed or assembled in parallel and sandwiched between upper and lower bamboo boards (Patent Document 2). . It is conceivable to make a pallet using this bamboo board. However, in this bamboo pallet, a vertically divided bamboo material is used for the load in the plate thickness direction (direction perpendicular to the plate surface). Since it receives, sufficient intensity | strength can be ensured.

  On the other hand, since it is necessary to receive a large load with a girder in a pallet, the load is performed using a wooden square. Here, the girder means a load for receiving a load of a load loaded on the pallet and forming a space for inserting a fork of a forklift below the pallet.

  However, when trying to produce a large amount of wooden girders, it becomes necessary to cut a large amount of trees, which not only leads to the destruction of the global environment, but also makes the pallet heavy.

  This invention makes it a subject to provide the girder | pallet for pallets which was light and had high intensity | strength, without causing environmental destruction in view of this problem.

  Accordingly, the pallet girder according to the present invention is a girder attached to the lower surface of a flat or box-type pallet, and is formed of a molded product of wood or wood powder, and has a frame that forms a vertical rectangle with both side surfaces open. The frame includes a pair of left and right side plates that closes the open surfaces on both sides of the frame, and a columnar member formed by rounding bamboo or bamboo powder or wood powder cut into a predetermined size and solidifying with an adhesive or resin. And a structural member that is vertically inserted between the upper side portion and the lower side portion and receives a load.

  One of the features of the present invention is that the girder is hollow. Thereby, weight reduction of a girder can be achieved.

  If the girder is hollow, there is a possibility that the load of the pallet cannot be received structurally. However, in the present invention, the structural member is provided vertically in the frame to receive the load, so that a large load can be reliably received. Can do.

  Bamboo grows at a growth rate of 3 to 4 years and is faster than trees that require several decades before they can be used. For example, bamboo is cut down in large quantities by thinning out two trees at a time. But it has little impact on the environment.

  Another feature of the present invention is that round bamboo, bamboo powder or wood powder is used for the structural member. As a result, a large number of lightweight girders can be produced without adversely affecting the global environment, and harmful substances are less likely to be generated even when incinerated.

  Still another feature of the present invention is that the frame is made of a molded product of wood or wood powder. Thereby, a pallet and a girder can be fixed by nailing, and attachment of a girder is easy.

  The structure of the pallet is not particularly limited, and when applied to a bamboo pallet described in Patent Document 1 or a pallet using a bamboo board described in Patent Document 2, the effect of the pallet itself is great, coupled with the weight reduction of the pallet itself. It can also be applied to plywood pallets.

  Further, the pallet may be a flat pallet or a box pallet. The girder of the present invention may be attached to the lower surface of the surface on which the luggage is mounted.

It is a perspective view which shows preferable embodiment of the beam for pallets which concerns on this invention. It is a disassembled perspective view which shows the said embodiment.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 and 2 show a preferred embodiment of a pallet girder according to the present invention. The girder 10 of this example is attached to the lower surface of a bamboo flat pallet 20 by nailing or the like.

  The flat pallet 20 is composed of narrow bamboo-like vertically divided bamboo materials obtained by vertically dividing true bamboo into equal widths, and a plurality of plate-like members are laminated so as to be orthogonal to each other and bonded with an adhesive. The laminated plate 21 is manufactured, and a structural member 23 in which true bamboo is cut to a predetermined size is interposed between the upper and lower laminated plates 21, and the side surfaces of the upper and lower laminated plates 21 are covered with the vertically divided bamboo material 22 and bonded. Has been.

  On the other hand, the girder 10 is configured by covering both side surfaces of a vertical rectangular frame 11 with thin plates 12 and fixing them by nailing or bonding. The vertical rectangular frame 11 is manufactured by using a material in which bamboo powder or wood powder is mixed with an adhesive, and is formed into a vertical rectangular shape with both side surfaces open. The cut structural members 13 are inserted vertically with a predetermined distance from each other to receive the load of the flat pallet 20.

  As described above, in this example, the flat pallet 20 and the girder 10 are hollow, so that the weight can be reduced.

  If the flat pallet 20 and the girder 10 are hollow, there is a concern that the structural weakening may occur, but in this example, the structural members 23 and 13 are provided vertically in the pallet 20 and the girder 10 to receive the load. Therefore, a large load can be reliably received.

  In addition, although bamboo is used for structural members, bamboo grows in 3 to 4 years. For example, by thinning out 2 trees from 12 trees, the impact on the environment will not be affected even if a large number of trees are cut at once. Because there are few, it does not adversely affect the global environment. In addition, harmful substances are rarely generated even after incineration.

  In the above example, a bamboo powder or wood powder molded product is used for the frame of the girder, but it is also possible to assemble the wooden board into a vertical rectangular shape.

  In addition, although bamboo bamboo cut into a predetermined size is used for the structural member of the girder, a molded product of bamboo powder or wood powder may be used.

  Further, the flat pallet made of bamboo is used for the girders of the present invention, but it can also be used for a flat pallet made of wood board or plywood, and can also be used for a box pallet instead of a flat pallet. .

  In addition, the girder is attached to the lower surface of the flat pallet, but a flat plate made of bamboo, wood board or plywood may be attached under the girder.
