Description

  The present invention relates to a method for manufacturing a wooden panel using domestic materials, and more specifically, a high-precision hole is drilled in the side surface of non-dried domestic material having a small diameter and large deformation during drying, and a round bar having substantially the same diameter as this. Panels are made by inserting frictional force around the hole by inserting (non-shrinking dry round bars, resin round bars, round steel, etc.), and then natural drying causes deformation of domestic materials, and further frictional forces. It is related with the manufacturing method of the wooden panel which accelerates | stimulates outdoor use of domestic timber by antiseptic pressure injection processing.

  The warmth and texture of timber are mainly used indoors, and when you look at the urbanized townscape, it overflows with materials such as inorganic concrete and metal. However, if timber can be used outdoors, it is possible to give a friendly impression to the streets, create a healing space for daily life, and promote effective use of abundant forests (forest resources) in Japan. . However, wooden structures installed outdoors are severely corroded and deformed when directly exposed to rain and wind, and may require repair or replacement in some cases, and use of wood outdoors tends to be avoided. There's a problem.

  Japan's planted forests were planted in large quantities as a Japanese policy from 1955 to 1940, and have entered the current harvest season after more than 50 years, and public spending aimed at reducing carbon dioxide by accelerating global warming In 2008, environmental thinning began in 2008, and domestic timber was over-supplied. Therefore, the timber price continues to fall.In particular, small-diameter thinned wood produced by environmental thinning has little utility value, promotes its use as a fuel for biomass power generation, and uses the carbon dioxide stored by trees for many years. There is a problem that it returns to the atmosphere instantly.

  Thinned wood is a by-product of thinning operations performed to protect forests. Conventionally, such thinned trees can be used because they are severely shrunk even after sawing and are subject to significant deformation such as cracking and twisting. It was difficult. Thinned trees are mostly small-diameter trees, have very little utility value, and are expensive to carry out, so they are often left in a thinned forest. In addition, an increasing number of forestry workers have recently given up costly thinning operations.

  Thinning work is carried out to promote the photosynthesis of trees, and is indispensable for producing good-quality timber. Leave thinned trees in the forest as they are, Neglecting the work not only hinders the proper growth of the forest, but also may result in a forest that is prone to mountain disasters such as landslides. Therefore, it can be said that the effective use of thinned wood is indispensable for protecting forests and revitalizing forestry. In the future, it can be said that the promotion of the use of thinned wood for construction, civil engineering, exteriors, etc. is an issue as artificial forests in each region mature. The “thinned wood” in the present invention is used as a concept including “small-diameter wood”.

  Thinned wood has a weakness in that it has a small diameter compared to mature wood, and its range of use is limited and shrinkage and deformation are large, so it is often used as wood chip, plywood, lamina, etc. Usage has been avoided. In addition, when making a panel from square wood, dried square wood is often used, and it can be said that it is very difficult to make a panel using raw square wood having a high moisture content. Conventional wood panels are mainly made by sticking wood with an adhesive or by fastening them with hardware. However, a wood panel using an adhesive is subject to deterioration due to secular change and gradually peels off. In addition, there is a problem that wood panels using adhesives and hardware are difficult to recycle and reuse. Therefore, it can be said that there is a demand for a technique for using a wooden structure using thinned timber and small-diameter trees outdoors and extending the useful life.

  Conventionally, various techniques have been proposed. For example, Patent Document 1 discloses a technique in which the name of the invention is “woody composite material and a method for producing the same”, and is a known technique (see Patent Document 1). Specifically, the object is to “provide a wood composite material produced by laminating a plurality of wood members and a method for producing the same”, and the solution means “from a bent wood material having a water content of 20% by mass or less” An inner layer lamina formed by laminating and bonding an outer layer lamina to be formed and a plurality of solid wood materials having a moisture content of 15% by mass or less directly, and having a shorter length than the outer layer lamina, and a longitudinal direction of the inner layer lamina The end lamina is made of wood and is approximately the same thickness as the inner lamina and has a moisture content of 15% or less. The inner lamina and the end lamina are laminated and bonded between the outer lamina, , A through hole is provided from one outer layer lamina to the other outer layer lamina, and a reinforcing member is inserted through the through hole. However, this technique has not yet solved the problem that wood is laminated and bonded, and the wood is fixed only by natural drying without using an adhesive.

  Patent Document 2 discloses a technique in which the name of the invention is “structural laminated material”, which is a known technique (see Patent Document 2). Specifically, the problem is to “provide a structural laminated material suitable for use as a beam having excellent shear characteristics even with a small cross-section”. And a plurality of rod-shaped shear reinforcement members arranged in a state of being arranged at a predetermined interval and in the vertical direction and integrally bonded to the wooden lamina ". . However, this technique has not yet solved the problem that wood is laminated and bonded, and the wood is fixed only by natural drying without using an adhesive.

  In addition, this inventor has received a patent by the technique which makes the name of invention "the manufacturing method of a thinning material utilization panel and the thinning material utilization panel manufactured by the manufacturing method" (refer patent document 3). Specifically, “Thinning thinning material panel manufacturing method that eliminates the problems of large deformation such as shrinkage and cracking of thinning material and makes it possible to use thinning material effectively, and thinning manufactured by that method. The solution to this problem is to provide a composite panel manufacturing method using thinned timber, and prepare approximately the same square timber made by processing thinned timber. The plurality of square bars are arranged in parallel, and at least one or more through holes for binding the square bars 2 arranged in parallel are formed, and metal bars are passed through the through holes, and the square bars are arranged in both end rows. The square bars arranged in parallel in the direction of the square bars arranged in the inner row are dried while being pressed, and after the completion of drying, both ends of the metal bars are fastened with a fastener and the pressurization is stopped. . However, it can be said that such a technique leaves the problem of using only wood without using hardware because the metal bars are passed through the square bars.

  Therefore, the present inventor pays attention to how the domestic timber can be configured to promote outdoor use, and the combination of domestic undried wood and dry timber is combined with preservative pressure injection treatment. The present invention has been completed, which enables low-cost and durable panel formation by subsequent natural drying.

It is a flowchart which shows the operation | work process which concerns on the cross pole type manufacturing method which concerns on this invention. It is a basic explanatory view explaining the basic composition of the cross pole wooden structure concerning the present invention. It is Example explanatory drawing explaining the Example of the cross pole wooden structure based on this invention. It is Example explanatory drawing explaining the other Example of the cross pole wooden structure based on this invention.

  In addition, since this invention is invention which belongs to two categories, the manufacturing method of the wooden structure 30, and the wooden structure 30 manufactured by the manufacturing method, first, the manufacturing method of the wooden structure 30 which concerns on this invention Will be described, and then the wooden structure 30 having a characteristic structure will be described. In addition, description of the structural member common to both a manufacturing method and a wooden structure is abbreviate | omitted about the overlapping part.

  FIG. 1 is a flowchart showing an operation process according to the manufacturing method of the present invention. As a whole, a wooden structure 30 manufactured by an undried wood processing step A, a dry wood processing step B, and an assembly step C, This is a manufacturing method for obtaining the cross pole wooden structure 2 by the consolidation step E. Hereinafter, each step will be described.

  The undried wood processing step A is a step of obtaining a timber whose shape and dimensions are adjusted in a state sufficiently containing moisture, which is obtained without drying in general lumber processing.

  The dry wood processing step B is the same as a general wood lumbering step, and is a step of obtaining wood whose shape and dimensions are adjusted after drying.

  The assembly process C is a process in which the plurality of undried wood 10 and the dried timber 20 obtained in the undried wood processing process A and the dried timber processing process B are assembled through the connecting hole portion 11, and hardware or adhesion It is a process of assembling without using a connecting member such as an agent. The connecting hole 11 has an inner diameter that is substantially the same as the outer diameter of the dry wood 20 and is joined by fitting the dry wood 20 into the undried wood 10. As the dimension crossing, an insertion state that is an interference fit is desirable.

  In the consolidation step E, the wooden structure 30 assembled in the assembly step D is dried after being installed on the land or the building, so that the undried wood 10 is caused by the action of the force generated from the deformation due to the drying. This is a process in which the undried wood 10 and the dried wood 20 are consolidated and firmly integrated over time.

  Preservative pressurizing injection step D is a step of injecting preservative 40 for the purpose of preserving and moistening for a long period of time. In the manufacturing method of the present invention, it is desirable to incorporate after the assembly step C. The pressurizing injection of the preservative 40 is performed in accordance with JISK4 at an AQ certified factory. In order to deeply infiltrate the wooden structure 30 with a large amount of chemicals, the pressure is reduced (0.08 MPa or more) and then pressurized (1.3 to 1.4 MPa), and then the excess chemicals attached to the surface. The pressure is reduced again (0.08 MPa or more). The injection amount of the chemical is pressurized for a long time until 200 kg or more per cubic meter is infiltrated. It should be noted that the preservative 40 is injected after the undried wood 10 and the dried wood 20 are assembled, so that the wooden structure 30 becomes wet, and the frictional force is increased by further deformation of the wood in subsequent natural drying. It will increase and the caking power will increase. As a result, it is possible to provide a wooden structure including a wooden panel that can be used outdoors for a long time.

  The preservative pressure injection step D will be specifically described. As the preservative 40, a safe one that can be disposed of in the same manner as ordinary wood is used without causing harmful metals to remain in the incinerated ash even if incinerated. Explaining the use of Tanaris CY (registered trademark), which is a copper compound and an azole compound and does not contain harmful heavy metals, will be explained. According to the preservative 40, the regulation is related to VOC (Volatile Organic Compounds). It does not use chloropyrifos and formaldehyde, and it does not use toluene, xylene, ethylbenzene, styrene, or acetaldehyde. This is a safe preservative 40 that does not have any adverse effects. Further, the preservative 40 has a track record of being used as a river maintenance structure, and is an excellent treatment chemical that can be incinerated similarly to the raw material during disposal. When Tanaris CY (registered trademark) is used, the color is slightly green, but it does not harm the cedar atmosphere, but rather has the advantage that the permeation state of the preservative 40 can be visually confirmed. However, without being limited to the preservative 40, for example, if you want to make use of the cedar wood color as it is, a group of alkylammonium compounds (AAC) made from coconut oil that is uncolored and does not change the texture of the material. DDAC (didecyldimethylammonium chloride), which is one of the antibacterial agents, may be selected as the drug to be used. Furthermore, for example, there are Pencure (registered trademark) ECO30 of an azole compound and a neonicotinoid compound, and DDAC-based Pentacure (registered trademark) New BM.

  The idea of the creation of the present invention is to effectively use thinned timber and small-diameter trees, such as cedar, especially outdoors, and most of the thinned timber and small-diameter trees are core support materials. Each of the characteristic structures of the wooden structure 30 according to the present invention is influenced by the arrangement structure of the core material of the core support material and the ratio between the core material and the sap material, etc. In order to describe the members, general features of wood will be described first, including points not shown.

  The core material is a portion close to the tree core, has less water than sapwood, and cedar often has a reddish color. Further, the core material is less likely to shrink and deform than the sapwood, and is generally regarded as a good material.

  The sapwood is a portion close to the epidermis away from the tree core, and has a lot of water and has a whitish color in comparison with the core material. In addition, the sapwood is a young part, and the amount of moisture that escapes during drying increases, resulting in large shrinkage and deformation.

  The core support material is a square material having the center of an annual ring, and is a wood having a core material by dropping four rounds of one tree by sawing. The core support material tends to bend toward the core, and if the back is not split, the surface tends to crack. Since the core support material is made of wood fibers, it has higher bending strength than the core removal material.

  The centering material is a material that is made by removing the center of the annual ring, and is made by avoiding the tree core in a thick log from which many pieces of square wood can be taken. If the core is not a large-diameter wood, the core material is expensive because the core material cannot be taken, but the bending strength is low because the core material is old and there is no core. Since most of the thinned wood is small-diameter wood, there is almost no core removal. However, since the present invention regulates the dry wood 20 through the undried wood 10 regardless of the presence or absence of the core material and the position of the core, the tree core can be used even if it is a core removal material.

  Back splitting is a process that is commonly used in wooden structures such as fences and gates, and saws up to the approximate center of the core support material, on the surface of the core support material where cracks can easily enter during the drying process, In order to prevent cracks and cracks, it is desirable to make a saw line at a depth that reaches the center from the beginning to the end of the surface that does not enter the field of view, and it is desirable to provide as necessary.

  FIG. 2 is an overall explanatory view illustrating the overall configuration of the cross pole wooden structure 2 according to the present invention. In FIG. 2, the structure of the wooden structure 30 according to the present invention is illustrated as a panel-like structure from the undried wood 10 and the dried timber 20. The connection hole part 11 looked down from is a top view which shows an installation state. The figure shown below the plan view is an elevational view showing an elevated surface in a state where the undried wood 10 is stacked. The figure shown on the right side of the elevation view is an elevation view showing the wife side in a state where the undried timbers 10 are stacked, and shows that each undried timber 10 is a core support material. The figure shown under the two elevations is an assembly explanatory view showing a direction in which the dry timber 20 with high dimensional accuracy is inserted from below to above.

  For the undried wood 10, it is desirable to use thinned wood, and a material having a high water content that has not undergone a drying process after logging is used. The reason for using the undried wood 10 in such a state is that a predetermined force is applied to the dried wood 20 by applying a clamping force, a holding force, or a pressing force by utilizing the property of being easily deformed in the process of evaporating moisture. It is a base material constructed in a shape.

  The dry wood 20 is a hard-to-deform timber, which is obtained by drying undried wood in order to obtain the hard-to-deform wood, and drying it to a state that does not exceed the moisture content defined by the JAS standard. It is. Normally harvested timber contains a lot of moisture, so it is heavy and has a heavy work load, and its deformation and shrinkage are extremely large. Therefore, it is not used as a general wooden building material. Specifically, the moisture content standard for structural lumbers and construction agents is set to 20% or less for finishing materials, and 19% or less for structural wall construction structural lumbers. However, the moisture content is only a characteristic of wood, and it is only necessary to combine wood that has a large deformation area due to drying with wood that does not have it, and it is a structure that is integrated by physical adhesion resulting from the difference in moisture content. If there is, it is not limited to such a numerical value, and the threshold value as a critical value is shown based on the JAS standard.

  Therefore, it is common to use dried wood even in the ordinary wooden structure 30. In the present invention, the wood that does not exceed the above-mentioned standard is the dry wood 20 according to the present invention, and the wood having a moisture content exceeding this is the undried wood 10.

  The present invention employs a configuration in which undried wood 10 is stacked in a horizontal direction and stacked, and the dried timber 20 (pole) is inserted into the connection hole 11 of the undried wood 10 in a direction in which the fibers are perpendicularly crossed. Therefore, the manufacturing method of the wooden structure 30 according to the present invention is referred to as a cross pole manufacturing method 1.

  The cross pole manufacturing method 1 according to the present application is characterized in that the wooden structure 30 is manufactured by combining the dry wood 20 and the undried wood 10. Conventionally, it is common sense to use wood after being dried in a wooden structure, and in order to avoid the disadvantage that the undried wood 10 is accompanied by large deformation and shrinkage, using a large drying apparatus or the like, Since the process was performed, the burden was heavy, and it can be said that the provision of the technique which reduces this was called for.

  In addition, in response to social demands for effective use of thinned timber and small-diameter wood of cedar and birch, by combining dry wood 20 and undried wood 10, the accuracy of dry timber 20 and deformation of undried wood 10 Increasing the fitting strength to improve the strength as a rigid body is one of the solutions to the problem. Hereinafter, the technique concerned is demonstrated based on drawing. In addition, the Example shown in drawing is only an illustration to the last, It is not limited to these structures, In this application in the range in which the effect exhibited by combining the dry timber 20 and the undried timber 10 is common. The effect of the invention extends.

  The structural member according to the present invention is likely to be deformed or stretched due to the removal of moisture due to the nature of the wood, and the deformation or stretch is also affected by the presence of the knots, grain, or the like. Therefore, using the undried timber 10 which is easy to deform with respect to the wooden structure manufactured with only the dried timber 20 in the prior art, the arrangement and orientation of each member considering such deformation and expansion / contraction are appropriate. is necessary. In addition, since the deformation | transformation and expansion / contraction produce the clearance gap 12 between adjacent undried timbers 10 and cause damage to the appearance, the occurrence of cracks and the like that occur during expansion / contraction and deformation is prevented, and other Consider the assembly process to cope with various changes.

  The connection hole 11 in the cross pole wooden structure 2 according to the present invention for manufacturing the wooden structure 30 by using the interference fit effect will be described. The connecting hole portion 11 is a hole for inserting and connecting the dry wood 20 to the undried wood 10, and regulates the deformation of the undried wood 10 using the dry wood 20 inserted through the hole as a guide. The inner diameter of the connecting hole 11 is a hole having substantially the same diameter as the outer diameter of the dry wood 20, and is joined by inserting the dry wood 10 and the dry wood 20. As the dimension crossing, an insertion state that is an interference fit is desirable, but even a cross that is a slight gap fit can be brought into a solidified state by subsequent deformation by natural drying.

  In addition, although not shown in drawing, the surface of the beautiful wooden structure 30 provided with the shaping | molding in which the connection hole part 11 is provided in the position which shifted the undried wood 10 slightly in a staggered manner, and a level | step difference is repeated is created. Is also possible. In this case, as a method of creating a modeling in which such steps are repeated, there is a method of alternating regular undried wood 10; however, by dividing the regular core holding material into two parts and dividing the core, According to the manufacturing method of the present application in which the dry wood 20 is inserted, it is possible to suppress warping and twisting caused by splitting into two while suppressing cracking.

  FIG. 3 is an embodiment explanatory view for explaining an embodiment of the cross pole wooden structure 2 according to the present invention. The structure shown in FIG. 3 is a panel-like structure in which air permeability is improved by opening a gap 12 between the undried woods 10, and can be said to be a structure suitable for a wooden structure 30 such as a fence. However, in this case, the load on the dry wood is likely to be increased and the load on the dry wood 20 is increased, so that the thickness is larger than that of the configuration in which the undried wood 10 is packed without opening the gap 12. And Unlike the lattices that have been manufactured so far, the back and front are the same reversible lattice. The fence created by this method should not be completely blindfolded, and should be a fence that is suitable for visually dividing land. Is possible. Furthermore, the structure having such a gap 12 can be used for a highly durable wood deck floor panel that easily drains water and does not rot easily.

  FIG. 4 is an embodiment explanatory view for explaining another embodiment of the cross pole wooden structure 2 according to the present invention. The structure shown in FIG. 4 is a state in which the gap 12 is provided between the undried timbers 10 in the same manner as in the above embodiment, and the connection hole 11 of the undried timber 10 is further inclined and provided. In this case, the non-dried wood 10 inclined with respect to the surface direction of the wall can be used as a fence or the like that enhances the blinding effect and provides ventilation. However, in this case, since the connecting hole 11 is inclined in the undried wood 10, a fixing jig or the like for drilling is required.

The present invention contributes to industrial development in the field of forestry by making effective use of thinned timber and small-diameter trees produced by thinning work essential for forest environment protection, and is a structure installed outdoors. By actively using wood as a material for materials, it can be considered that the carbon neutral environment is maintained and it contributes to environmental conservation on a global scale, but industrial applicability is considered high.
