Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heavy goods pallet using a metal plate and wood.

[0002]

[Prior art]

 Wooden pallets are commonly used as heavy pallets. In this structure, a plurality of wooden columns are arranged at appropriate intervals, and a large number of wooden horizontal plates are nailed and fixed to the upper and lower surfaces of the wooden columns. Metal pallets are rarely used for heavy goods. The reason for this is that the metal pallet is so light that it is not crushed, so it is not suitable for heavy objects, and it is also possible to reinforce the metal pallet so that it does not crush. This is because if it is reinforced, the weight will increase and the cost will increase, making it impractical.

[Problems to be solved by the device]

 When a conventional wooden pallet becomes old, it is likely to be deformed into a diamond shape and the nails are easily lifted. If the nail floats and projects, the projection may damage the product. For this reason, it was necessary to carry out regular repairs so that the protrusion of nails would always disappear. When replacing a damaged horizontal plate, the nail is first removed, the damaged horizontal plate is removed, a new horizontal plate is prepared, and the nail is driven in for repair. In this case, there is generally no spare new horizontal plate to replace a damaged horizontal plate and it must be prepared each time. In other words, wooden pallets are generally dedicated to each product, and the length, width, and thickness of the horizontal plates vary, so it is necessary to prepare a new one each time, which is troublesome. There was a point.

The present invention is to provide a heavy-duty pallet that is inexpensive, lightweight, and easy to repair and maintain.

[0005]

Means for Solving the Problems The present invention has been made to solve the above problems. That is, a plurality of grooves are formed on the upper and lower surfaces of a wooden support by bending a thin metal plate. A large number of formed horizontal plates are laid out, and a heavy material pallet is constructed from a composite material of wood and metal.

Then, a pilot hole is drilled from the groove (11) of the horizontal plate (1) placed on each wooden strut (2) by a drill or the like, and a nail (4) is inserted into the pilot hole and driven by a hammer or the like. Fix two boards (1) to each wooden column (2). After fixing, the next three horizontal plates (1) also have one end of the connecting metal fitting (3) inserted into the groove (21) in the same manner as described above, and the horizontal plate (1) placed on each wooden column (2). After making a prepared hole in the groove (11) and driving the nails (4) in order, the two horizontal plates (1) are also fixed to the upper surface of the wooden strut (2), so that the horizontal plate (1) is fixed. is there. The three horizontal plates (1) connected together are mounted and fixed on both sides of the connection fitting (3) fixed to the two horizontal plates (1) connected together. . Further, when the nail (4) can be directly driven into the horizontal plate (1) by using an air nailing machine for the nailing work, the prepared hole is not necessary. Next, after fixing all the horizontal plates (1) on the upper surface side of the wooden columns (2), the whole is inverted. Then, the horizontal plate (1) is sequentially fixed to the wooden support columns (2) as described above. When using the lightweight connecting metal fittings (3) shown in FIGS. 3 and 4, the grooves (21) of the wooden columns (2) arranged on both sides are unnecessary, and the nails (4) are attached from both sides. By striking, the horizontal plate (1) is securely fixed to the wooden column (2).

Next, the operation of the present invention will be described. When the heavy pallet of the present invention is old like a conventional wooden pallet and the nail (4) is lifted up as shown in the phantom line in FIG. 2, even if it protrudes from the groove (11) upper surface of the horizontal plate (1). It does not protrude from the upper surface of the horizontal plate (1), and there is no risk of being caught by the product and damaged. Therefore, the protruding condition of the nail (4) is regularly inspected, and there is no problem even if the repair is delayed, so that the repair can be planned. Further, according to the present invention, one end of the substantially C-shaped cross section of the connecting metal fitting (3) is inserted into the groove (21) of the wooden supporting pillar (2), or the side surface of the wooden supporting pillar (2) has the connecting metal fitting (3). Since it is fixed to the lateral plate (1) with the nails (4), the conventional deformation is almost eliminated. Moreover, standardization of the horizontal plate (1) enables partial replacement, and the replacement horizontal plate (1) can be easily obtained.
