Description

  The present invention relates to a recycling method for dismantling a wooden flat pallet and reusing it as a used material, as well as a regenerated used material and a construction method using the same.

  The wooden flat pallet used for the cargo handling work by the forklift includes those according to the JIS standard and the like. Since the wooden flat pallet is required to have a predetermined load resistance (0.5 t to 2 t), it becomes unusable when the strength decreases due to aging, and must be processed as waste material.

  FIG. 7 is a diagram showing some types of wooden flat pallets according to JIS standards. In this figure, S2 (single-sided two-way), SU2 (single-sided single-wing two-way), D2 (single-sided two-way), D4 (single-sided four-way), DP4 (single-sided) Eight types are shown: hollow type), DU2 (single-sided single-wing type two-way insertion), R4 (double-sided usage type four-way insertion), and RW2 (double-sided double-wing type). Other types include S4 (single-sided four-way insertion), SP4 (single-side punched-out type), and R2 (double-sided use two-way insertion).

  A plurality of plate materials (deck board and edge board) are arranged in parallel only on the upper surface or both upper and lower surfaces with a gap or block for spacing the insertion port. The height of the insertion port is 75 mm to 100 mm. The total height of the wooden flat pallet is the sum of the thickness of one or both sides of the plate material. It is a rectangle in plan view, and its length or width is 800 mm to 1200 mm.

  In Patent Document 1, as a recycling method of a wooden flat pallet, a deck board is manufactured by crushing used wooden pallet components with a crusher and hot-pressing the chopped pieces of wood with a binder. It is described to form. This deck board will be used for a new wooden flat pallet.

Registered Utility Model No. 3116272

  Although used wooden flat pallets have reduced strength for cargo handling work, they have sufficient strength as non-structural members such as floor materials and wall materials in the construction field. Moreover, since load resistance is required, relatively good quality wood is used. In addition to this, the texture of the surface has a unique texture due to aging. Therefore, a used wooden flat pallet can be a promising material as an old material for construction or as an old material for furniture or decoration. However, at present, most wooden flat pallets are treated as waste.

  In view of the above situation, an object of the present invention is to provide a processing method for reusing a wooden flat pallet as a used material, that is, a method for regenerating a wooden flat pallet into a used material. It is to provide an old material and a construction method using the same.

In order to achieve the above object, the present invention has the following configuration.
A first aspect of the present invention is a method for recycling a wooden flat pallet to an old material, which is fixed to the edge board and the deck board in the longitudinal direction, which are arranged in parallel with the pallet width direction, and the both ends. Cutting the wooden flat pallet in the pallet length direction so as to separate the two end portions including the bamboo or the block and the plank from the central portion, and for each of the cut end portion and the central portion, an edge A step of separating the board and deck board from the block and the board, a step of extracting the nail remaining on the separated edge board and deck board, and a step of sawing the edge board and deck board from which the nail has been extracted It is.

The 2nd aspect of this invention is the used old material recycled by the reproduction | regeneration method to the old material of said wooden flat pallet.
The 3rd aspect of this invention is the construction method using the old material which fixes the old material reproduced | regenerated by the reproduction | regeneration method to the old material of said wooden flat pallet with respect to the foundation | substrate of construction object.

  ADVANTAGE OF THE INVENTION According to this invention, a used wooden flat pallet can be reused effectively as an old material for construction or furniture and decorations. Although the thickness and length of wooden flat pallet deck boards and edge boards are almost the same, although there are variations depending on the type, many old materials of the same size should be produced compared to general waste materials. Is easy. Further, the thickness and length of the deck board and edge board of the wooden flat pallet are close to the appropriate size as a flooring material and a wall material, so that a large processing is not required when used as an old building material. According to the present invention, it is possible to obtain a large amount of old materials having a unique texture due to aging.

Embodiments of the present invention will be described below with reference to the drawings showing examples of the present invention.
1 (a) and 1 (b) are perspective views showing an example of a wooden flat pallet to which a method for recycling a wooden flat pallet to an old material according to the present invention is applied. First, the basic structure of a wooden flat pallet will be described with reference to this figure.

  FIG. 1A is a perspective view showing an example of a wooden flat pallet 1 corresponding to JIS standard R2 (double-sided two-way insertion). The wooden flat pallet 1 has a digit 13 made of three square bars arranged in parallel to the opposite two sides and the intermediate position thereof, and a plurality of rectangular flat plates arranged and fixed on the upper and lower surfaces of the digit 13, respectively. And materials 11 and 12. The flat plates 11 and 12 are fixed in a direction intersecting with the digits 13. An insertion port V for a forklift is formed between adjacent digits 13.

  The plurality of flat plates 11 and 12 arranged on one surface are arranged in parallel with each other. The gap between adjacent flat plates is appropriate. A pair of flat plates indicated by reference numeral 11 arranged on the outermost side is referred to as “edge board”. A plurality of flat plates indicated by reference numeral 12 disposed between the pair of edge boards 11 are referred to as “deck boards”. For simplicity of illustration, only two deck boards 12 are shown. However, three or more deck boards 12 may be used, and the board widths of the edge board 11 and the deck board 12 may be different.

  In general, for wooden flat pallets, the direction indicated by the symbol W is referred to as “pallet width direction”. The pallet width direction is the same as the longitudinal direction of the edge board 11 and the deck board 12. A direction perpendicular to the pallet width direction and a direction indicated by a symbol L is referred to as a “pallet length direction”.

  FIG. 1B is a perspective view partially showing an example of another type of flat wooden pallet 10 corresponding to JIS standard D4 (single-sided four-way insertion). In the case of four-way insertion, a block 14 and a board 15 are used in place of the digit 13 used in two-way insertion. The substantially cubic blocks 14 are arranged at the four corners of the wooden flat pallet 10 and at intermediate positions between the sides. An insertion port V is formed between adjacent blocks 14. Then, three planks 15 which are flat plates are passed and fixed on the upper surface of the block 14 along the pallet length direction of the wooden flat pallet 10. The edge board 11 and the deck board 12 are fixed to the upper surface of the plank 15 along the direction intersecting with the plank 15, that is, the pallet width direction.

  Since the wooden flat pallet 10 is used on one side, the lower surface is not used for cargo handling, but the edge board 11 and the deck board 12 are fixedly connected to the lower surface of each block 14 arranged in the pallet width direction. Although not shown in the figure, as another example, in the case of using both sides, a board 15 is inserted and fixed to the lower surface of the block 14, and the edge board and the deck board are fixed in a direction crossing the lower surface.

  In this way, the wooden flat pallet uses a square 13 that is a square member when the insertion port is provided in two directions in order to form a height direction gap between the upper surface and the lower surface, and the insertion port is arranged in four directions. In the case of providing in the block, a block 14 and a plate 15 are used.

  For fixing the edge board 11 and the deck board 12, a nail 16 such as a screw nail or an iron round nail is used.

  Tree species used for wooden flat pallets include red pine, black pine, rice pine, karamatsu, rice pine, kaban, beech, apiton, kapoor, town, lawan, bintangor, and red meranti. . Uses relatively high-quality wood because it does not bend, warp, curl, twist, crack, hole, worm-eaten, crucible, crab, skin, discoloration, comb, etc. Has been.

  As shown in FIG. 7 described above, there are many kinds of JIS standard wooden flat pallets to which the present invention can be applied. Furthermore, the present invention can be applied to wooden flat pallets similar to these.

  Next, with reference to FIGS. 2-5, each process of the reproduction | regeneration method to the old material of a wooden flat pallet is demonstrated. Here, the wooden flat pallet 1 shown in FIG. 1A will be described as an example, but the same applies to other types of wooden flat pallets.

  2A and 2B are perspective views schematically showing a cutting process of the wooden flat pallet 1. FIG. 2A shows a state at the start of cutting, and FIG. 2B shows a state after completion of cutting.

  In the cutting step, the wooden flat pallet 1 is cut using an appropriate cutting tool T such as an electric circular saw. The cutting is performed along two straight lines C1 and C2 indicated by dotted lines in the drawing. The straight lines C1 and C2 are located at a predetermined distance from both ends in the pallet width direction. The predetermined distance is a distance from each end to the inner edge of the digit 13 located at the end, and the straight lines C1 and C2 are located immediately inside the digit 13 along the inner edge. The two end portions to be separated include both end portions of the edge board 11 and the deck board 12 in the longitudinal direction, and digits 13 fixed to these both end portions.

  As another example, although not shown in the figure, in the case of a wooden flat pallet connected by the block 14 and the plank 15 as shown in FIG. 1B, it is cut along the inner edge of the plank 15. In that case, the two end portions to be separated include both end portions of the edge board 11 and the deck board 12 in the longitudinal direction, and blocks 14 and planks 15 fixed to the both end portions.

  When the cutting at two places is completed, one central portion 1A and two end portions 1B are obtained as shown in FIG. The edge board 11 and the deck board 12 are also cut into long plate members denoted by reference numerals 11a and 12a and rectangular plate members denoted by reference numerals 11b and 12b, respectively. According to this cutting method, the fixed portions at both ends of the edge board 11 and the deck board 12 are cut off, and only the middle fixed portion remains in the central portion 1A, so that the next separation step can be easily performed. Become.

FIG. 3 is a perspective view schematically showing a separation process of the edge board and the deck board.
Each of the two end portions 1B and the central portion 1A cut in the process shown in FIG. 2 is separated from the edge board 11a, 11b and the deck board 12a, 12b. For example, using a hand tool such as a flat bar, it is inserted like a wedge into the gap of the joint and separated. An electric tool may be used. Since only the middle of the long edge board 11 and the deck board 12 is fixed, the center portion 1A can be easily peeled off by the action of the wedge. At the time of separation, the nails 16 remain on the edge boards 11a and 11b and the deck boards 12a and 12b. On the other hand, a nail hole 17 appears in the digit 13.

  As another example, in the case of a wooden flat pallet connected by a block 14 and a plank 15 as shown in FIG. 1B, the edge boards 11a and 11b and the deck board 12a are separated from the block 14 and the plank 15. , 12b are peeled off and separated.

FIG. 4 is a perspective view schematically showing the nail extraction process of the edge board and the deck board.
The nail 16 remaining on the edge boards 11a and 11b and the deck boards 12a and 12b separated in the process shown in FIG. 3 is extracted using a hand-held tool such as nail extraction. At this point, nail holes 17 appear in the edge boards 11a and 11b and the deck boards 12a and 12b.

  Then, the lumbering process of the edge boards 11a and 11b and the deck boards 12a and 12b is performed. In the lumbering process, planing of the surface is performed using a planar machine or the like. Moreover, you may cut | disconnect to the desired length and width as needed. In particular, the edge board 11a and the deck board 12a having a sufficient length are useful because the length adjustable range is large. Further, if necessary, the surface is filed with a manual tool or a power tool. The rectangular edge board 11b and the deck board 12b having a short length can also be effectively used as necessary in order to form various designs such as floors, walls, furniture, and ornaments.

  In this way, the wooden flat pallet is recycled as an old material. This old material can be used as an old material for construction, and can also be widely used as an old material for producing furniture, ornaments and the like.

  FIG. 5 is a perspective view showing an example of a construction method using an old material regenerated from a wooden flat pallet. Fig.5 (a) shows the base material 2 of construction object. For example, wall base materials and floor base materials such as plywood and structural plywood. FIG. 5B is a view showing a state after the construction in which the old material 19 regenerated from the edge board and deck board of the wooden flat pallet is fixed to the base material 2. The old material 19 is nailed to the base material 2 using a tool such as a nail finish or a pin tucker, for example. As another example, affixing is performed with an adhesive or an adhesive material.

  When fixing the old material 19 on the surface of the base material 2, the old material 19 having various sizes and colors can be used in combination. By utilizing the texture of the surface of the old material 19 and arranging individual pieces in a vertical, horizontal, and diagonal manner, it is possible to construct walls and floors of various designs. Similarly, when used for furniture, ornaments, etc., various designs can be made by combining old materials 19 of various sizes and colors.
