Description

  The present invention relates to an antiseptic treated wooden casket and a method for producing the same, and more particularly, without performing processing such as cutting after the antiseptic treatment, without exposing the non-preservatively treated part to the surface, and on the connecting surface. The present invention relates to a wooden casket capable of maintaining an antiseptic effect for a long period of time by providing a groove for promoting penetration of the preservative, and a method for producing the same.

  Thinning is intended to enhance the photosynthesis of trees by thinning out dense trees in the growth process of the forest, and to increase the value of building materials by selecting good seedlings by picking out bad seedlings. It also has the effect of stabilizing the human living environment, such as creating an environment where undergrowth can grow easily by allowing sunlight to reach the forest floor, preventing soil outflow and preventing sediment disasters. Therefore, forest thinning and thinning can be said to be extremely important childcare work for forest management.If a large amount of thinned wood and products using thinned wood are distributed, the forest will be improved and carbon dioxide will be generated. Therefore, it is necessary to make full-scale efforts to increase consumption of thinned wood and to actively promote the use of thinned wood.

  However, when looking at the distribution of timber in Japan, since the high economic growth period, cheap timber has come in large quantities from overseas, and non-wood products such as plastic and vinyl products have increased. Demand for domestic timber is decreasing, especially thin and weak timber like thinned wood has low utility value, especially cedar thinned wood is softer than other trees, so it can be used as a material for building structures. It can be said that usage is extremely low.

  The wooden fence that can be said to be a traditional building from ancient times is often used for the fence surrounding the site of a Japanese-style house. The wooden caskets are different from inorganic metal caskets and concrete caskets, and the beauty of modeling that appeals to the sensibility of warmth, softness, or luxury peculiar to organic materials, and the natural wood grain and annual rings are excellent in design, and the beauty that arises from these textures It is easy to create.

  However, wooden cocoons have the disadvantage that they tend to rot and lack durability. In conventional wooden caskets, the preservative was applied directly or immersed in the preservative for a long time, but the preservative period obtained by these treatments is as short as several years. Currently, the mainstream is changing to concrete block fences because of the need for maintenance such as re-coating. Perishability is one of the main reasons for the shrinking demand for wood.

  At present, the preservative pressure injection treatment technology is advancing, and it can be said that a technical proposal that can solve these problems by further applying such technology is desired.

  In view of the above problems, various techniques have been proposed in recent years. For example, in a fence composed of a column, a trunk edge, a panel, and a lid for the top of the column, and a panel is mounted between the trunk edges that are vertically mounted between the columns, a leg with a hollow structure is provided at the lower end of the column. There are plastic fences (see Patent Document 1) that are provided, and synthetic resin fences (see Patent Document 2) having a frame made of FRP columns and trunk edges and a PET net. However, since the technology uses plastic as a material, if it is used for a wall surrounding a site such as a house, a texture such as a profound feeling becomes a problem.

  In addition, when installing the underground part of the wooden column and the above-ground part, that is, the column leg part, in the ground, the root winding concrete, the ground, or the underground part of the water, surround the column leg with a solid bottom protective material. Protective antiseptic method for wooden props, characterized by providing a gap between the wooden support and the solid bottom protective material, injecting an antiseptic into this gap, and closing the top with a caulking material, and using this There is a wooden structure (see Patent Document 3). However, such a patented invention is to improve the anticorrosive effect by impregnating the inner core part of the wooden column that prevents the preservative from adversely affecting the natural environment, thereby enhancing the anticorrosive effect. Can not.

  In addition, in a wooden fence composed of pillars that are embedded in the ground with their lower ends embedded at predetermined intervals and horizontal members that are laid between these pillars, the horizontal members are formed by insizing processing. There has been proposed a technique of a wooden fence that has a group of pits that are impregnated with an antiseptic inside, and in which a support column is made of karamatsu and a horizontal member is made of cedar (Patent Document 4). However, in such a technique, a large number of pit groups by insizing processing are engraved on one side over the entire length on both the front and back sides, so that dots or streaks intentionally formed at the tooth tips of a gear, etc. A group of macroscopic concave holes is formed, each of which has a depth and length of 2 to 5 mm, so that there is a problem that the aesthetic appearance is impaired.

JP-A-8-296348 JP-A-9-279910 Japanese Patent No. 3704537 JP-A-11-350800

  Therefore, the present invention has been made in view of such problems, and in a wooden fence surrounding the site, paying attention to the viewpoint of effective use of cedar thinning and the property of easily absorbing water of cedar, The purpose of the present invention is to provide a wooden casket capable of maintaining a high antiseptic effect over a wide range and a method for producing the same.

  In order to achieve the above-mentioned object, the present invention is a method for producing a wooden cocoon using thinned cedar, in which a cedar thinned timber made into a substantially square cross section is cut into a predetermined length to form a heel part. A step of obtaining a plurality of scissors members, a step of drilling at least two connecting holes for connecting the scissors members between the joining surfaces of the scissors members, In the case where the split groove for improving the permeability and inducing a thousand cracks is formed at least one set on the bonding surface, and the foundation portion for standing the collar portion is a fabric foundation, A step of forming a hole for inserting an insertion round steel bar at one end of the bar member disposed at a position, and a barb member formed through the first step, Place them side by side on the jig so that they face each other, and insert the connecting member through the connecting hole. The second step in which the entire configuration of the collar portion is formed by fastening firmly with the fastening portions provided at both ends of the connecting portion, and the panel-like collar portion obtained in the second step is subjected to preservative pressure injection treatment Thus, a third method of applying antiseptic treatment, and a method for manufacturing a wooden casket using a thinned cedar of a cedar structure.

  Further, the present invention provides the above-mentioned thinning material of cedar, wherein the preservative used in the third step is Tanaris CY (trade name) which is a copper compound and an azole compound and does not contain harmful heavy metals. It can also be set as the manufacturing method of the wooden coffin used.

  Further, the present invention comprises a wooden casket manufactured by any one of the above manufacturing methods, and a foundation for standing the wooden casket on the land, wherein the foundation is a cloth foundation type, A wooden cocoon using a cedar thinning material having a structure in which the cloth foundation and the wooden cocoon are erected through an insertion round steel bar.

  Further, the present invention comprises a wooden casket manufactured by any one of the above-described manufacturing methods, and a base portion for erecting the wooden casket, the base portion being a moat type, It is also possible to make a wooden cocoon using a thinned cedar of a constitution characterized in that the cocoon member at a predetermined location to be configured has a protruding length for concrete placement.

  In this document, the vertical direction refers to the longitudinal direction of the flange member, and the direction perpendicular thereto is referred to as the horizontal direction. Moreover, the upper direction shall mean the upward direction with respect to the ground surface to be constructed.

  According to the wooden fence and the method for producing the same according to the present invention, effective use of cedar thinned wood having a low utilization rate can be promoted, and photosynthesis can be promoted by discharging the thinned wood from the forest. It has the excellent effect of being able to plan various problems in forests, such as the cultivation of high-priced timber and the sediment discharge disaster caused by the cultivation of undergrowth.

  In addition, the Government of Japan has decided to absorb about 2/3 of the CO2 reduction target for forest absorption due to the entry into force of the Kyoto Protocol. Currently, forest maintenance (thinning) is actively being carried out, but it is carried out from degraded plantations. Most of the logs are long and thin and have no utility value, so they are not profitable even if they are carried out. However, according to the wooden fence and the manufacturing method thereof according to the present invention, the utilization technology of the small-diameter thinned lumber does not leave the remaining thinned lumber, so that unused thinning only for the environmental improvement "cutting thinning thinning" Contributes to returning to the original thinning, and has the beneficial effect of increasing forest absorption by leaving no remaining trees.

  In addition, according to the wooden fence and the manufacturing method thereof according to the present invention, in order to preserve the tree without rotting, it exhibits an excellent effect of being able to fix CO2, and after thinning as described above. Since the remaining trees can be prevented from being left, the excellent effects of having two environmental effects of not causing the generation of moisturizing effect gas and methane gas due to decay of the remaining trees are exhibited.

  Moreover, according to the wooden fence and the manufacturing method thereof according to the present invention, unlike a stone-made block fence or stone fence, there is an excellent effect that it does not collapse even during an earthquake and has high safety.

  Also, cedar wood is soft and unlike softwood, so it is not suitable for outdoor products. If it is used outdoors without antiseptic treatment, it will start to corrode in about three years at the earliest. Moreover, even if a heartwood that does not rot easily is used, it has only a durable period of about 4 years. However, according to the wooden fence and its manufacturing method according to the present invention, while utilizing the characteristic of easily absorbing the moisture of the cedar thinned wood, it is possible to penetrate the preservative more deeply by providing a split groove, The antiseptic effect is longer than the conventional one. Specifically, about 17 years ago (1994), wood that belongs to the copper-azole system (CuAz), a copper-based water-soluble chemical that does not contain arsenic, chromium and other harmful metals in timber thinning The sound insulation wall (example of use in Tohoku Expressway Otani Parking) produced by preserving the antiseptic / anticidal agent Tanaris (registered trademark) CY, etc., using the pressure-type antiseptic treatment method (JIS-A9002) is currently discolored However, there is a track record of not finding a decayed place, but this sound insulation wall does not have a split groove. Therefore, in the present invention in which the “slit groove” is provided rather than the soundproof wall, since the preservative penetrates more into the interior, it exhibits a long-term antiseptic effect as compared with the construction example of the soundproof wall. Can be expected.

  Further, according to the wooden coffin according to the present invention and the method for manufacturing the same, since the split groove is provided in the coffin member from the coupling surface toward the center, by intentionally inducing a thousand cracks from the coupling surface, There is an excellent effect that it does not cause cracks on the front and back surfaces of the part, and has a long-term aesthetics and safety that prevents injury when touched by a person.

  Moreover, according to the wooden coffin and the manufacturing method thereof according to the present invention, since the coffin member to be used is a square member having a substantially square cross section, it is harder to burn than a coffin using a plate material, and if the surface is carbonized, it is more than that. Because it does not burn, it has an excellent effect of having a high function as a fire wall. Further, in a flat plate material, distortion such as warping due to secular change is likely to occur, but in the present invention, the cross-section of the flange member is substantially square, and the connecting member is inserted through the connecting hole so that the connecting portion Since the entire hook part is configured by being firmly fastened by the fastening parts provided at both ends, an excellent effect is obtained that the hook part is difficult to warp.

  Moreover, according to the wooden fence and its manufacturing method which concern on this invention, since there is little reflection of sunlight compared with a concrete fence, the effect which suppresses the temperature rise by reflection is also exhibited.

  Also, according to the wooden fence and the manufacturing method thereof according to the present invention, the annual rings of cedar thinned wood appear as they are, instead of the inorganic cold feeling like a concrete fence. It gives the person who sees the skin a healing effect such as softness and warmth, and has an excellent effect of showing various facial expressions depending on the dryness, water-containing condition, or aging.

  The present invention utilizes the characteristics of cedar by utilizing thinned cedar, and the split groove 22 is provided on the coupling surface 23 so that the permeability of the preservative and the surface of the buttock 10 are not cracked. The most important feature is that the preservatives are injected under pressure after assembly and no processing is performed thereafter. The best mode for carrying out the present invention will be described below with reference to the drawings. However, the dimensions shown in the examples are considered to be the best for implementation, and are not limited to these dimensions, and can be changed within the scope of the technical idea considered as the main part of the creation of the present invention. Is.

  FIG. 1 is a process diagram showing the steps of the method for manufacturing a wooden casket according to the present invention, and FIG. 2 is an explanatory perspective view showing the configuration of the casket member 20 according to the present invention. 2A is an explanatory perspective view showing the configuration of the eaves member according to the first embodiment, and FIG. 2B is an explanatory perspective view showing the configuration of the eaves member according to the second embodiment.

  The first process is a process that includes a cedar thinning cutting process, a connecting hole drilling process, a split groove forming process, and a cloth foundation bonding drilling process as necessary. do not have to.

  The cedar thinning material cutting step cuts a cedar thinning material having a side of about 60 mm to 120 mm, and more preferably a cross-sectional shape with a side of 90 mm being approximately square, into a predetermined length. The length to be cut is determined by design based on the basic method and the height of the ridge. For example, if the height of the ridge is 1500 mm from the base and the width of one panel is 990 mm, all 11 of the cloth foundation 60 will be 1500 mm, and in the case of the moored foundation, the ridge members on both sides and the center of one panel. 20 becomes 1950 mm which added the protrusion part 26 which becomes the height (for example, 450 mm) of the earth frame D from the discarded concrete S placement surface, and the remaining 8 gutter members 20 become 1500 mm.

  The connecting hole drilling step is a step of drilling at least two connecting holes 21 for connecting the flange members 20 to each other so as to connect the connecting surfaces 23 of the flange members 20. Is determined according to the height of the buttock 10. For example, when the height of the eaves part 10 is as low as 1000 mm or less, it is provided at two locations about 50 mm inside from both ends of the eaves member 20 in the dug foundation specification. In contrast to this, if the height of the collar portion 10 is about 1500 mm, it is also provided in the vicinity of the middle of the three places. For example, if the steel wire used for the connecting member 30 is 8 mm, the hole diameter is drilled using a drill of about 8.2 mm to 8.5 mm. In addition, when using the cloth foundation 70, since the round steel for insertion is inserted in the bottom part of the collar member 20, it cannot be overemphasized that it becomes a position which avoids this.

  The split groove forming step is a step of forming a predetermined groove over the entire length of the flange member 20, and the split groove 22 is a groove for improving the permeability of the preservative and inducing thousand cracks. At least one set is formed on the coupling surface 23. Specifically, the thickness of the groove is, for example, about 1 mm to 2 mm, which is a typical thickness of a circular saw, and the depth depends on the thickness of the rod member 20, for example, a substantially square cedar having a cross-section of 90 mm on one side. If the timber is made of thinned wood, the depth is 10 mm to 20 mm. In the drawing of FIG. 2, the split groove 22 is provided in the direction perpendicular to the coupling surface 23, but since the cracks tend to run in the center direction, the split groove 22 should be provided in the center direction if possible. Is more desirable. The presence of such grooves promotes penetration of the preservative and prevents the cracks from being generated on the front and back surfaces 24 of the buttocks 10 by intentionally inducing a thousand cracks from the bonding surface 23, and has a long-term aesthetics. It is designed to be safe so that people are not injured when touched. The groove is formed by adjusting the protruding amount of the blade with, for example, a guided circular saw or table saw.

  In the drilling step for connecting the fabric foundation, when the foundation portion K for standing the collar portion 10 is the fabric foundation 60, the insertion round steel bar 50 is inserted into one end of the collar member 20 arranged at a predetermined position. If the width of a single panel is set to 990 mm, out of 11 of the heel members 20, the heel members 20 on both sides and the center of the panel are formed. A hole for inserting the insertion round steel bar 50 is drilled at the end of the hole. Specifically, for example, if the insertion round steel 50 is 50 mm in diameter and the insertion length of the gutter member 20 is 300 mm, the hole is processed from the prepared hole, and finally the insertion hole diameter is 50 mm. . A hole that allows the insertion round steel bar 50 to be press-fitted is formed by interference fitting with an intersection of ± 0.

  In the second step, the connecting member 30 is passed through the connecting hole 21 from the jig arranging step in which the flange members 20 formed through the first step are arranged side by side on the jig so that the coupling surfaces 23 face each other. In a process in which the entire configuration of the collar part 10 is formed by a fastening process in which the fastening parts 31 are firmly fastened by fastening parts 31 provided at both ends of the coupling member 30 through a coupling member penetration process of inserting and coupling a plurality of collar members 20. is there. For example, when the elbows are arranged in a substantially square shape with one side of the flange member 20 being 90 mm, the panel width becomes 990 mm.

  In addition, necessary processing such as surface finishing, corner chamfering, and step removal after fastening, etc. shall be finished by the second step, and polishing and grinding shall not be performed after the next third step. . In the case of cedar thinned wood, a barrier layer of about 10 mm can be constructed from the surface or groove by pressure infiltration performed in the third step, but if the surface or the like is shaved, the anticorrosion period is shortened accordingly. .

  The third step is a step of pressure-injecting the preservative with the preservative pressure-injection processing device 40 on the panel-shaped flange 10 obtained in the second step. Use preservatives that are safe and can be disposed of in the same way as normal wood, without leaving harmful metals in the incinerated ash even when incinerated. In the manufacturing method according to claim 2, it is specifically specified to use Tanaris CY (registered trademark) which is a copper compound and an azole compound and does not contain harmful heavy metals. According to such preservatives, chlorpyrifos and formaldehyde that are regulated in connection with VOC (Volatile Organic Compounds) are not used, and toluene, xylene, ethylbenzene, styrene, and acetaldehyde are not used. Therefore, it is a safe preservative that does not adversely affect human skin even if it directly touches the cocoon and does not adversely affect animals or plants. The preservative 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 when discarded. When Tanaris CY (registered trademark) is used, it is slightly colored green, but it does not harm the cedar atmosphere, but rather has the advantage that the preservative penetration can be visually confirmed. In the manufacturing method of the wooden coffin according to claim 1, without being limited to such an antiseptic agent, for example, if it is desired to make use of the cedar wood color as it is, the coconut oil is not colored and the texture does not change. DDAC (didecyldimethylammonium chloride), which is one of the antibacterial agents in the group of alkylammonium compounds (AAC) used as a raw material, may be selected as the drug used. Specifically, for example, pentacure (registered trademark) ECO30 of an azole compound and a neonicotinoid compound, and DDAC-based pentacure (registered trademark) New BM.

The preservative pressure injection process is performed at an AQ certified factory, and a process equivalent to JISK4 is performed. In order to deeply infiltrate a lot of chemicals, the material that has been naturally dried until the moisture content of the cedar is 30% or less, is depressurized (0.08 MPa or more) and then pressurized (1.3 to 1.4 MPa), and then In order to eliminate excess chemicals attached to the surface of the wood, injection of chemicals is performed in the process of reducing the pressure again (0.08 MPa or more). Pressurize until the amount of chemical injection is 200 kg or more per 1 m ³ . The pressurization is about 2 hours.
