Description

  The present invention relates to wood for joinery such as fences, doors, and flash doors, and a method for manufacturing the same.

  A structural material (core material) that constitutes the frame (frame) of a wooden fitting such as a fence, a shoji, and a flush door is obtained by cutting a timber having a predetermined standard size according to the design dimensions of the structural material. . At this time, a cut piece (hereinafter referred to as “timber piece”) shortened to such an extent that it cannot be used as a structural material of the wooden joinery is generated.

  For example, for a joinery with a regular size of 1.9 m in length, which can be easily obtained from a sawmill, etc. When obtained from timber, approximately 0.1 m of timber pieces are produced. In this way, when a structural material for joinery is obtained from a joinery timber having a fixed size, for example, a piece of timber of about several centimeters to several tens of centimeters is generated.

  In addition, a cover material such as a paperboard or a decorative board (Lawan plywood, MDF) to be bonded to the frame is also obtained by cutting from a base material having a predetermined standard size according to a design dimension, as described above. . Also in the case of obtaining this cover material, a remaining piece (hereinafter referred to as “surface material piece”) after the cover material is cut from the base material is generated.

  In the past, these timber pieces and cover pieces were difficult to reuse at low cost, and were mainly treated as industrial waste. Therefore, effective utilization of material resources has not been made. Moreover, the waste disposal cost was reflected to the manufacturing cost of joinery.

  The present invention recycles the above-mentioned timber pieces and cover material pieces at as low a cost as possible, thereby effectively utilizing the materials for the joinery and reducing the manufacturing cost of the joinery related to industrial waste treatment. The purpose is that.

  In order to achieve this object, the feature of the manufacturing method of wood for joinery of the present invention is that a plurality of timber pieces are arranged on the bottom surface so that they are in contact with each other and the height (thickness) from the bottom surface is aligned. In the plurality of arranged timber pieces, the plurality of timber pieces are connected to each other by applying connection means from the upper surface side which is the surface opposite to the lower surface facing the bottom surface.

  In joinery wood manufactured by such a manufacturing method, a plurality of timber pieces are in contact with each other and are arranged in a flat plate shape so as to have a uniform thickness. The plurality of timber pieces are integrated with each other by connection means provided on at least one surface along the arrangement direction of the plurality of timber pieces. The integrated piece of timber constitutes a flat joinery timber having a substantially uniform thickness. And the said wood for joinery can be utilized again as a structural material for joinery by being cut | disconnected to a required dimension.

  As described above, according to the present invention, it is possible to easily and reduce the recycling of structural material raw materials by a very simple process in which timber pieces, which are timber pieces generated in the manufacturing process of joinery, are simply arranged and connected to each other by connecting means. Can be done at a cost.

  Here, as the connection means, for example, an adhesive tape, a resin (particularly an adhesive such as an adhesive for woodworking), or the like can be used. Further, it is preferable that the connection means is applied to both the upper surface and the lower surface.

  When an adhesive tape is used as the connecting means, the length of the adhesive tape corresponds to the external dimension in plan view of the flat plate shape when a plurality of timber pieces are arranged in a substantially flat plate shape (that is, the external dimension). It is preferable that the length is set to be approximately equal to the length. In other words, it is preferable that the adhesive tapes in one row are integrally formed without being joined.

  In addition, it is preferable that the timber pieces are cut from a timber having a fixed size having the same nominal size of the outer shape in a cross section orthogonal to the longitudinal direction.

  Here, “standard size” timber is distributed in the market as timber sawn for joinery (that is, commercially available at sawmills, etc.) with a predetermined expected and found size and a predetermined length. Of timber.

  In addition, the “standard size” timber includes a timber having a predetermined length with a predetermined expected / finding dimension defined in various standards such as the Japanese Agricultural Standard (JAS Standard) and standard specifications.

  In addition, timber of “standard size” is stocked with timber of a predetermined length with a predetermined expected / finding dimension defined in the above-mentioned standards / standard specifications, etc., cut in advance for a predetermined purpose. (For example, joinery timber that has been pre-cut to a length suitable for the largest size joinery and stocked by joinery manufacturers in order to be able to handle custom-made production of multiple sizes of joinery) Is also included.

  Furthermore, the manufacturing method of the wood for joinery of this invention has suitably the following processes.

  First, a plurality of timber pieces cut out from a timber of the above-mentioned standard size having the same nominal dimension of the outer shape in a cross section orthogonal to the longitudinal direction are in contact with each other in the mold fixed on the bottom plate and the bottom plate Are arranged in a substantially flat plate shape so that their heights from the top surface are aligned.

  Next, with respect to the upper surface, which is the surface opposite to the lower surface facing the bottom plate, of the plurality of timber pieces arranged in the substantially flat plate shape, the length corresponding to the outer dimension in plan view in the substantially flat plate shape By sticking the adhesive tape, the plurality of timber pieces are connected to each other.

  Subsequently, a flat lid plate is placed from above the mold, and after the top and bottom of the mold are inverted, the mold and the bottom plate are removed from above.

  And the adhesive tape of the length corresponding to the external dimension of the planar view in the said substantially flat plate shape is affixed on the said lower surface of the said several timber piece exposed upwards, The said some timber piece Are integrated.

  Another feature of the manufacturing method of wood for joinery according to the present invention is that a plurality of timber pieces are arranged on a plane so as to be in contact with each other and have a height from the plane, and the plurality of arranged timbers. In the timber pieces, by bonding a cover material for joinery to the upper surface that is the surface opposite to the lower surface facing the plane, the plurality of timber pieces are connected to each other via the cover material, The plurality of timber pieces are integrated by bonding the cover material to the lower surface of the plurality of timber pieces.

  Another feature of the present invention is that the plurality of timber pieces are arranged so that their grain directions are aligned. Thereby, when it reuses as a structural material for joinery, it becomes easy to cut into a desired dimension.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a schematic structure of a skeleton of a cocoon.

  The configuration of the frame 20 that forms the skeleton of the bag is as follows. First, the rectangular frame-shaped peripheral bone 21 is constructed by connecting the horizontal stiles 21c and 21d to the upper and lower ends of the same length of the heels 21a and 21b arranged in parallel along the vertical direction in the figure. Has been. Further, corner plates 22 are respectively attached to the inner sides of the corners of the four corners of the surrounding bone 21. In addition, a plurality of brace braids 23 and horizontal braids 24 are suspended inside the surrounding bone 21.

The plurality of horizontal braids 24 are stretched along the left-right direction between the firewood town 21a and the firewood town 21b, and are arranged so as to be parallel to each other and at a constant interval.

  And between two near the center in the up-and-down direction (height direction) of the kite among the plurality of horizontal braiding units 24, there is a pulling anchor plate 25 for attaching the pulling handle 30 so as to contact the kite town 21a. It is attached.

  Here, in the present embodiment, the expected dimensions (the depth direction, that is, the width in the direction perpendicular to the paper surface in FIG. 1) are the stiles 21a and 21b, the side stiles 21c and 21d, the corner plate 22, the sash braid 23, Expected dimensions of the horizontal braid 24 and the pulling lever board 25 are substantially the same. On the other hand, with respect to the finding dimension (the width seen from the front, that is, the width in the direction parallel to the paper surface in FIG. 1), the finding dimensions of the stiles 21a and 21b and the side stiles 21c and 21d are the same. 23 and the horizontal dimension of the horizontal braiding 24 are the same.

  The structural material such as the surrounding bone 21, corner plate 22, braiding 23, horizontal braiding 24, and the like constituting the frame 20 as described above is a predetermined size designed from a fitting lumber having a predetermined size. Obtained by being cut into pieces.

  FIG. 2 is a diagram showing a state in which timber pieces are generated when the structural material such as the firewood town 21a shown in FIG. 1 is obtained from the timber for joinery having a fixed size.

  As shown in FIG. 2, the hook towns 21a and 21b are obtained by cutting a joinery timber having a fixed length A, and a timber piece A1 is generated from the remaining portion. Similarly, by cutting a piece of joinery timber having a length B, horizontal stiles 21c and 21d are obtained, and a timber piece B1 is generated from the remaining portion. Moreover, the braid 23 is obtained by cutting the timber for joinery having a length C, and a timber piece C1 is generated from the remaining portion. Moreover, the horizontal braid 24 is obtained by cut | disconnecting the joinery timber whose length is the fixed dimension D, and the timber piece D1 arises from the remaining part. In addition, as the handle anchor board 25, the plate-shaped member previously cut | disconnected by the predetermined dimension is used.

  FIG. 3 is a diagram illustrating a schematic structure of a flash door and a state in which a piece of timber and a cover material piece are generated when a structural material and a cover material of the flash door are obtained.

  As shown in FIG. 3, the flash door 110 is composed of a frame body 120 that forms the skeleton, and a decorative board 130 that is a cover material attached to the frame body 120.

  The configuration of the frame 120 is as follows. First, a rectangular frame-shaped peripheral bone 121 is formed from vertical cores 121a and 121b extending vertically on both left and right sides, and an upper core 121c and a lower core 121d extending horizontally on both upper and lower sides. A plurality of cores 124 are stretched around the inner bone 121. The plurality of middle cores 124 are stretched between the vertical cores 121a and 121b along the left-right direction, and are arranged so as to be parallel to each other and at a constant interval. A handle core 125 is flushed between the two middle cores 124 at approximately the center in the vertical direction (height direction) of the flash door 110 and at both ends in the width direction of the flash door 110. A plurality of doors 110 are attached along the vertical direction of the door 110.

  Here, in the flash door 110 according to the present embodiment, the expected dimensions of the vertical cores 121a and 121b, the upper core 121c, the lower core 121d, the middle core 124, and the handle core 125 are all the same.

  As shown in FIG. 3, the vertical cores 121a and 121b are obtained by cutting a joinery timber having a fixed length A ', and a timber piece A1' is generated from the remaining portion. Similarly, the upper core 121c, the lower core 121d, and the handle core 125 are obtained by cutting the lumber for joinery having a fixed length A ', and a lumber piece A2' is generated from the remaining portion. Further, the center core 124 and the handle core 125 are obtained by cutting the timber for joinery having a length A ′, and the timber piece A3 ′ is generated from the remaining portion. In addition, the decorative board 130 is cut from the decorative board material having the fixed dimension E × F, and the cut ends E1 and F1 as the surface covering material pieces are generated from the remaining portion.

  4 recycles the timber pieces G (the timber pieces A1 to D1 in FIG. 2 and the timber pieces A1 ′ to A3 ′ in FIG. 3) generated when manufacturing the coffin and the flash door as described above. It is a figure for demonstrating one method for obtaining wood for joinery.

  In the method of this embodiment, the formwork box 50 and the cover plate 53 are used. The mold box 50 includes a bottom plate 51 having a rectangular shape in plan view and a frame 52 formed by combining four frame members 52a to 52d in a rectangular shape in plan view. The four frame members 52a to 52d have a height (about 3 to 5 mm lower than the expected dimensions of the structural members such as the stiles 21a and 21b, the side stiles 21c and 21d, the sash assembly 23, and the horizontal assembly 24). (Expected dimensions). That is, when the timber pieces generated when obtaining the structural material such as the firewood stile 21a are placed on the bottom plate 51 of the mold box 50 so that the expected dimension is in the height direction, the frame 52 The formwork box 50 is configured so that the upper end of the timber piece protrudes by about 3 to 5 mm from the upper end of the sheet so that subsequent operations such as sticking of an adhesive tape can be easily performed.

  Further, the size of the formwork box 50 can be appropriately selected according to the size of the joinery wood to be obtained (the joinery wood G1 in FIG. 4C). For example, the length of the longer frame members 52a and 52c is about 600 to 2100 mm, and the length of the shorter frame members 52b and 52d is about 150 to 900 mm.

  Next, a specific method for reusing the timber pieces G to obtain the joinery wood G1 will be described with reference to FIG.

  First, as shown in FIG. 4 (a), the timber piece G is formed so that the direction of the expected dimension is the height direction from the bottom plate 51 and the grain direction is aligned as much as possible. 50 are arranged in one layer. At this time, the timber pieces G having the same size are arranged in close contact with each other in the row direction (lateral direction in FIG. 4), so that the plurality of timber pieces G forming the same row form one square piece. Can be arranged as follows. Then, a plurality of rows of the timber pieces G are formed, and the arrangement of the timber pieces G of the plurality of rows is brought close to the adjacent frame members 52a and 52b of the four stiles in the frame 52, so that The timber pieces G are arranged in a substantially flat plate shape so as to be in close contact with each other in the direction of the finding dimension.

  Subsequently, an appropriate number of adhesive tapes 60 as connection means (connection layers) are attached to the upper surface of the timber pieces G arranged in a substantially flat plate shape in the formwork box 50. The pressure-sensitive adhesive tape 60 has a length corresponding to the dimension in the longitudinal direction in a substantially flat plate shape made of timber pieces G arranged in the formwork box 50 (for example, a length longer by about 1 to 2 cm than the dimension in the longitudinal direction). And / or an adhesive tape 60b formed to a length corresponding to the dimension in the width direction orthogonal to the longitudinal direction (for example, a length longer by about 1 to 2 cm than the dimension in the width direction). Is used. These adhesive tapes 60a and 60b are preferably formed integrally so that there is no joint in the middle.

  Subsequently, as shown in FIG. 4B, the top and bottom of the mold box 50 is reversed (turned over) with the cover plate 53 placed from above.

  Then, the mold box 50 is removed, and as shown in FIG. 4C, the back surface of the surface of the timber piece G to which the adhesive tape 60 is pasted (the bottom plate 51 in FIG. 4A). The same number of adhesive tapes 60 (60a, 60b) as those described above are appropriately attached to the contact surface). In this manner, the joinery wood G1 is obtained by substantially integrating the plurality of timber pieces G so as not to fall apart.

  The joinery wood G1 obtained in this way has an expected dimension substantially the same as the expected dimension of the structural material such as the braid 23, the horizontal braid 24, and the center core 124. Therefore, the joinery wood G1 can be reused as a raw material of the structural material by being cut to a predetermined size. And since these structural materials are covered with the covering material, they are not exposed to the outside. Accordingly, the joinery wood G1 can be suitably used as a raw material of the structural material.

  In particular, the joinery wood G <b> 1 is preferably used as a raw material for the pulling lever board 25. That is, it is preferable that the pulling lever board 25 is formed by cutting the joinery wood G1 in accordance with a predetermined design dimension.

  In this case, when the cover material is affixed to the frame 20 after the pulling anchor board 25 is mounted, an adhesive such as glue enters the gaps between the plurality of timber pieces. In addition, the cover material is attached to both the upper and lower surfaces of the pulling anchor board 25 with an adhesive such as glue. Thereby, the said handle anchor board 25 will be in the state reinforce | strengthened by the surface covering material adhere | attached through adhesives, such as glue which penetrate | invaded into the clearance gap between several timber pieces G, and adhesives, such as glue. Therefore, the said handle anchor board 25 after a cover material is affixed on the frame 20 has the favorable intensity | strength as if it was one board | plate material.

  The handle 30 is finally fixed to the handle anchor plate 25 with a nail, an adhesive, or the like. Here, when the handle 30 is fixed by a nail, the adhesive layer of the adhesive tape 60 adheres to the nail when the nail is driven into the position where the adhesive tape 60 is affixed on the handle anchor plate 25. . On the other hand, when the nail is pulled out and the handle 30 is once removed to replace the cover material of the bag, the adhesive force between the nail and the adhesive tape 60 does not become an obstacle when the nail is pulled out. . Therefore, by constructing the pulling lever board 25 from the joinery wood G1, it is possible to prevent the nail from falling out of the pulling lever board 25 without hindering the workability of removing the nail when changing the covering material. .

  FIG. 5 is a view showing a state where a new joinery plate material G1 'is obtained using a plurality of the joinery wood G1 described above.

  First, as shown in FIG. 5A, a plurality of joinery wood G1 formed in a rectangular shape in plan view is prepared. In order to obtain such a rectangular joinery wood G1, an irregular shape such as the joinery wood G1 shown in FIG. 4 may be cut into an appropriate size. Alternatively, by appropriately selecting the size of the timber pieces to be reused (for example, selecting only timber pieces of the same size), the joinery wood G1 can be formed in a rectangular shape from the beginning without the need for cutting.

  Next, as shown in FIG. 5B, the plurality of rectangular joinery timbers G1 are arranged in a flat plate and brought into close contact with each other. And the board | plate material P of the same material and the same dimension (same thickness) is affixed on both surfaces of the upper surface and lower surface of these some wood lumber G1 for joinery.

  Examples of the plate material P include, for example, a standard size (specifically, dimensions in plan view are about 1800 mm × about 900 (920) mm, about 2100 mm × about 900 (920) mm, about 2400 mm × about 900 (920). Inferior goods of the veneer plate material having a thickness of 1.5 to 3 mm, such as mm, can be reused as the plate material P. Moreover, as a board | plate material P, a paperboard, a lauan plywood, MDF, a decorative board, etc. can be used.

  The attachment of the plate material P can be performed, for example, by performing press working using an adhesive.

  As a result, as shown in FIG. 5C, a joinery wood G1 'is obtained in which the plate material P is bonded to both surfaces of a plurality of timber pieces almost integrated by an adhesive tape. Here, the adhesive tape (the adhesive tape 60 in FIG. 4), the plate material P, and the plate material P and the joinery wood G1 are bonded to the joinery wood G1 ′ and the connection means (connection layer) in the manufacturing method thereof. For the adhesive.

  It can be said that the joinery wood G1 'is obtained by reinforcing the joinery wood G1 with the plate material P and the adhesive. Accordingly, the joinery wood G1 ′ is cut into an appropriate size so that it can be used in addition to the handle pulling anchor plate 25 shown in FIG. 1 and the handle core 125 of the flash door 110 shown in FIG. 1 to 3 can be more suitably used as a raw material for the structural members (such as the brace 23 and the center core 124) that constitute the flash and the flash door.

  FIG. 6 is a diagram for explaining a method of newly obtaining a lumber for joinery by reusing the above-mentioned lumber pieces G and the cut ends E1 and F1.

  First, as shown in FIG. 6A, a plurality of timber pieces G are arranged in a substantially flat plate shape. Next, the cut ends E1 and the like are bonded to one surface exposed upward in the plurality of timber pieces G arranged in a substantially flat plate shape. Thereby, the several timber pieces G are mutually connected by the cut end E1 or the like. Note that the arrangement of the timber pieces G and the bonding of the cut ends E1 and the like as described above can be performed using a formwork box similar to the formwork box 50 in FIG.

  Here, as shown in the drawing, the cut ends E1 and F1 are attached individually one by one when the width is wide (for example, 10 cm or more). When the width is narrow (for example, less than 10 cm), a plurality of sheets are abutted and attached to the upper surface of the timber piece G in a state of being temporarily fixed by the temporary fixing tape 61 (the temporary fixing tape 61 is then peeled off). .

  Subsequently, the plurality of timber pieces G connected by the cut ends E1 and the like as described above are turned over (after pressing and drying).

  Then, as shown in FIG. 6B, the cut end E1 having the same material and thickness as the cut end E1 in FIG. Glued.

  As described above, the joinery wood G2 as shown in FIG. 6C is obtained. Here, the board | plate material P and an adhesive agent correspond to the connection means (connection layer) in the said wood G2 for joinery, and its manufacturing method.

  The surface of the joinery wood G2 thus obtained is constituted by the surface of the cover material, and the adhesive tape is not exposed on the surface of the joinery wood G2. Therefore, when it is used again as a structural material, the adhesion with the cover material is improved. It can also be used for parts that appear in appearance. Further, the joinery wood G2 is reinforced by the cut ends E1 and the like and an adhesive. Therefore, this joinery wood G2 can be satisfactorily used as a structural material for all parts.

  Note that the plate material P having the above-mentioned standard size may be used instead of the lumber piece E1 or the like as in the case of a joinery plate material G2 'in FIG. As a result, long structural members such as eaves hooks 21a and 21b in FIGS. 1 and 2 and vertical cores 121a and 121b of flash door 110 in FIG. 3 can be obtained by reusing the timber pieces. .

  FIG. 7 is a diagram showing details of a method for obtaining a large-sized joinery plate G2 'as described above.

  First, as shown in FIG. 7 (a), for example, inside the formwork box 50 having a plane size corresponding to a plate material (plate material P in FIG. 6) having a fixed size such as about 1800 mm × about 900 mm, A plurality of timber pieces G are arranged in a substantially flat plate shape. The configuration of the form box 50 is the same as that in FIG. The arrangement of the plurality of timber pieces G is the same as described above.

  Next, as shown in FIG. 7A, a plate material P ′ is attached to the upper surface of the plurality of timber pieces G arranged in the formwork box 50 via an adhesive. . This adhesive is applied to the upper surface of the timber piece G and / or the lower surface of the plate material P ′.

  Here, as the plate material P ′, a single plate material having a fixed size similar to the plate material P in FIG. 6 described above may be used.

  Further, as the plate material P ′, a plurality of plate materials having a width smaller than the above-mentioned standard size may be used. In this case, a plurality of plate members are arranged on the plurality of timber pieces G.

  Subsequently, as shown in FIG. 7B, the formwork box 50 in a state in which a plurality of timber pieces G each having a plate material P ′ attached to the upper surface via an adhesive is accommodated in the press machine 90. The pressure is applied for a predetermined time.

  Then, after the adhesive is cured, the mold box 50 is turned over, and the top and bottom of the mold box 50 is inverted as described above.

  Further, as shown in FIG. 7C, a plate material P ′ having the same material and the same dimensions (same thickness) as the plate material P ′ is attached in the same manner as described above.

  As described above, according to the method for manufacturing a wood for joinery by reusing a piece of wood or the like generated in the manufacturing process of a fence or a flash door as in the present embodiment, the fixed-size dimensions with the expected dimensions are aligned. Simply timber pieces from joinery timber are arranged in a substantially flat shape with the expected dimensions aligned and joined together by adhesive tape or the above-mentioned cut ends, etc. It is possible to very easily obtain wood for joinery that can be effectively used as an anchor board or a braid.

  Thereby, the said timber piece etc. are utilized effectively again as a resource, and a waste disposal cost is reduced. Moreover, the cost for reusing the timber pieces or the like as resources is extremely low.

  Note that the present invention is not limited to the above-described embodiment, and can be appropriately modified as long as the essential part of the present invention is not changed.

  For example, the piece of timber to be reused is not limited to the piece of timber that is produced during the manufacture of the above-described fence or flush door. For example, a piece of timber produced during the manufacture of a shoji or door is also preferably used.

  Moreover, if the operation | work which arranges the several timber piece G in FIGS. 4-6 in a substantially flat plate shape is performed on a substantially flat work table, the formwork box 50 shown in FIG. It is possible without using it.

  Moreover, the structure of the formwork box 50 used for the joining operation | work of the timber piece shown by FIG. 3 can also be deform | transformed suitably. For example, when a plurality of timber pieces can be joined on a certain flat work table, the bottom plate 51 may be omitted. Further, the expected dimension of the frame 52 may be the same as the expected dimension of the structural material. Further, the expected dimension of the frame 52 may be about several mm longer than the expected dimension of the structural material. Furthermore, the expected dimension of the frame 52 may be increased to, for example, about 20 to 40 mm so that the frame 52 can correspond to timber pieces having a plurality of types of expected dimensions.
