Description

  The present invention relates to an insect-proof structure of a wooden building that prevents damage to a building caused by insects such as termites.

  Wooden buildings may be damaged by termites. Since termites prefer warm, dark, and humid environments, there are many foundations, such as under the floor, which are particularly humid and poorly ventilated. However, termites can crawl up from the foundation and damage the structural materials of the entire building, including foundations, pillars, and attics. Termites enter the structure material such as pillars and gradually eat away from the inside, so it is difficult to check the damage from the outside of the building. Therefore, as a result of the damage proceeding without the knowledge of the resident, there was a risk that it would be too late and could be severely damaged, or costly for large-scale extermination or repair. In order to prevent termites from entering the structural material, conventional termite countermeasures include spraying a liquid termite inhibitor under the floor or pillars in advance, or injecting termite repellents into pillars, etc. The method of doing is known. For example, Patent Document 1 discloses a termite extermination method in which a small hole is formed in a part of a structural material such as a pillar material, a disinfectant is injected into the hole, and then a wooden plug is fitted in the hole to close the hole. Has been. The wooden plug described in Patent Document 1 has a short spindle shape in which one end is thick and the other end is thin, and the constant width portion is raised so as to be in close contact with the inner wall of the hole on the thick one end side.

Japanese Utility Model Publication No. 53-53171

  In the conventional method of spraying a termite inhibitor under the floor, labor and time are required for spraying, but the effect of the drug is relatively short and cost-effective. Moreover, in the extermination method like patent document 1, after making a hole in a work site, the process of inject | pouring a chemical | medical agent into a hole back and the process of fitting a wooden plug in a hole are required, and time and effort are required. It took. Further, after the treatment, the structural material such as the columnar material has a gap in the space in which the chemical is injected, so that there is a concern about the strength of the structural material. In addition, the structure material is separately operated only for the purpose of preventing termites, which is inefficient.

  The present invention has been made in view of the above-mentioned conventional problems, and one of its purposes is that it can be easily constructed, and can achieve an efficient structure by combining the insect-proofing effect and the improvement of seismic strength. It is to provide an insect-proof structure for wooden buildings that can be maintained for a long time.

  In order to solve the above-mentioned problems, the present invention is an insect-proof structure provided at a portion where two structural materials are connected in a wooden building. The tenon 16 provided on the first structural material (12), and the tenon 16 Are inserted in a direction perpendicular to the tenon 16 and the tenon 18 with the tenon 16 fitted in the tenon 18. The mortise 16 and the mortise 16 are inserted through the mortise 16 at the same time so as to prevent the mortise from being fixed. The insert 22 is provided on the insertion tip side F of the insert 22 and is a solid or kneaded insect repellent. The tip drug part 24 carrying 36 and the outer peripheral surface of the insertion plug 22 are formed long from the insertion distal end side F toward the insertion proximal end side R, and the insect repellent component can be guided from the distal drug part 24 along the outer peripheral surface. One or a plurality of guide grooves 26 Consisting of insect repellent structure 10 of the wooden buildings. The insect-proof structure 10 of a wooden building can be applied to either a new building or an existing building. The plug 22 may be preliminarily immersed or injected with a liquid insect repellent. The shape of the plug 22 may be an arbitrary shape such as a polygonal column or a column. Moreover, if the insertion tip F of the plug 22 is provided so as to become gradually tapered toward the tip, workability is good. Further, a plurality of insertion plugs 22 may be inserted and fixed to one connecting portion 20 formed by the tenon 16 and the tenon hole 18. Termites creep up gradually from the ground to the foundations and pillars, so it is effective in preventing termites when applied to the joints between the foundations and pillars. Further, a liquid insect repellent may be applied to the peripheral surface of the structural material. The synergistic effect of internal and external insect repellents can prevent damage to buildings more reliably.

  Alternatively, the guide groove 26 may be filled with a solid or kneaded insect repellent 37 in advance. Although it is not necessary to pre-fill the guide groove 26 with the insect repellent 37, a high insect repellent effect can be maintained for a long period of time by adopting a pre-filled configuration.

  Further, the distal drug portion 24 may be recessed from the insertion distal end of the insertion plug 22 to the inside, and may have an accommodation recess 38 for accommodating the insect repellent 36 inside. When accommodated in the accommodating recess 38, the entire insect repellent 36 may be completely accommodated, or a part of the insect repellent 36 may be accommodated in the accommodating recess 38 and the remaining portion exposed to the outside.

  The housing recess 38 and the guide groove 26 are preferably communicated with each other through a communication hole 42 that is drilled from the outer peripheral surface side to the inner side of the plug 22. In particular, when the entire insect repellent 36 is accommodated in the accommodating recess 38, the communication hole 42 may be provided.

  The guide groove 26 may include a spiral groove 40 that spirals around the outer peripheral surface of the bayonet plug 22. One or a plurality of spiral grooves 40 may be provided.

  In addition, the guide groove 26 may include a long groove 44 that is linearly long from the insertion distal end side F to the insertion proximal end side R of the insertion plug 22. A plurality of long grooves 44 may be provided in the circumferential direction of the plug 22.

  According to the insect repellent structure of a building of the present invention, the insect repellent structure is provided at a portion where two structural members are connected in a wooden building, and the tenon provided on the first structural member is fitted to the tenon. A mortise provided in the second structural member and inserted into the mortise in a direction perpendicular to the mortise and the mortise while being inserted into the mortise, A spigot for retaining and fixing, and the spigot is provided on the insertion tip side of the spigot and has a tip drug part carrying a solid or kneaded insect repellent, and an insertion tip on the outer peripheral surface of the spigot Since it has one or a plurality of guide grooves which are formed long from the side toward the insertion proximal side and can guide the insect repellent component from the distal drug part along the outer peripheral surface, the first structure material and the second structure As a result of being able to also use insect repellent means for the plug to fix the material In addition to improving the earthquake resistance of the connecting portion of the forming member can be favorably prevented building damage due to termites or beetles like entering the interior of the structural member. That is, it is possible to specifically realize an earthquake-proof and insect-proof structure that combines the strength improvement of a building and the insect-proof function with an efficient structure. Furthermore, since the insect repellent is provided integrally with the bayonet, the insect repellent can be installed at the same time by simply inserting the bayonet into the portion where the mortise and mortise are fitted. And it can be reliably constructed. In addition, even when the plug is inserted, the insect repellent component spreads around the plug by the guide groove, so that a high insecticidal effect can be expected over a wide range inside the structural material. In addition, since a large amount of insect repellent can be held in the tip drug part, the insect repellent effect can be maintained for a long time.

  Further, by adopting a structure in which the solid or kneaded insect repellent is filled in advance in the guide groove, a high insect repellent effect can be expected over a wide range inside the structural material, and the insect repellent effect can be maintained for a long time.

  In addition, the tip drug portion is recessed on the inner side from the insertion tip of the insertion plug, and has a housing recess for receiving the insect repellent therein, so that the insect repellent is reliably provided on the tip side of the insertion plug. Can do. In addition, the insect repellent is difficult to drop off and easy to handle when storing, carrying, or constructing the plug.

  Further, the housing recess and the guide groove are configured to communicate with each other through a communication hole drilled from the outer peripheral surface side to the inner side of the plug, so that the insect repellent component is communicated from the insect repellent accommodated in the housing recess. Can be reliably guided into the guide groove.

  In addition, the guide groove includes a spiral groove that spirals around the outer peripheral surface of the plug, so that the insect repellent component can effectively function around the plug with a simple configuration.

  In addition, the guide groove includes a long groove formed linearly from the insertion distal end side to the insertion proximal end side, so that the guide groove can be simplified without being influenced by the shape of the insertion plug. It can be realized by configuration.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the insect-proof structure of a building according to the present invention will be described below with reference to the accompanying drawings. The insect repellent structure of the building of the present invention is an insect repellent structure for preventing a wooden building from damage by insects such as termites and bark beetles. FIG. 1 thru | or FIG. 6 has shown 1st Embodiment of the insect-proof structure of the building based on this invention. As shown in FIGS. 1, 2, 3, and 4, in this embodiment, the insect-proof structure 10 of a wooden building is applied to, for example, a wooden frame building, and includes two structural members made of wood ( 12, 14) are provided in a connection portion (joint portion) 20 in which the tenon 16 and the tenon hole 18 are fitted and connected to each other. The insect-proof structure 10 of a wooden building includes a tenon 16 provided in the first structural material (12), a mortise 18 provided in the first structural material (14), a tip drug portion 24, and a guide groove 26. And a built-in stopper 22. In the present embodiment, for example, the first structural material will be described as an example of a pillar material 12, and the second structural material will be described as an example of a base 14. The first and second structural materials are not limited to the pillar material and the foundation, and may be any two structural materials connected in the building.

  As shown in FIGS. 1, 3, and 4, in a wooden building, a pillar material 12 made of square material is vertically erected at a predetermined position of a base 14 made of square material laid horizontally on a foundation (not shown), They are connected by a so-called mortise or mortise joint structure. Specifically, for example, a rectangular parallelepiped tenon 16 projecting along the longitudinal direction of the pillar material is formed at the lower end (small edge) of the pillar material 12. As shown in FIGS. 2 and 4, a circular through-hole penetrating perpendicularly to the rectangular surface is formed at a substantially central position of the tenon 16 to form a first plug hole element 28. A mortise 18 penetrating in the vertical direction is formed in a portion corresponding to the shape of the tenon 16 of the column member 12 at a portion for receiving the column member 12 at the intermediate position (or end side) of the base 14. Corresponding to the position where the mortise 18 is provided in the base 14, a second plug hole drilled in the horizontal direction so as to be orthogonal to the penetration direction of the mortise 18 from one outer surface side 14 a. Element 30 is provided. The second plug hole element 30 is formed of a circular hole, but does not completely penetrate the base 14 in the width direction, and is a blind hole for leaving a little material from the other side surface. The first plug hole element 28 and the second plug hole element 30 have the same hole diameter. With the tenon 16 of the column 12 fitted in the mortise 18 of the base 14, the first plug hole element 28 on the tenon 16 side of the column and the second plug hole element 30 on the base 14 side communicate with each other. A hole-shaped plug hole 32 is formed. The plug 22 is inserted into the plug hole 32. The plug hole 32 may be formed with a tool such as a drill with the tenon 16 and the tenon 18 fitted. Further, before fitting the tenon 16 and the tenon hole 18, holes of the same size may be formed in advance.

  As shown in FIGS. 1 and 3, the plug 22 is inserted in a direction perpendicular to the tenon 16 and the tenon hole 18 in a state where the tenon 16 of the column member 12 is fitted in the tenon hole 18 of the base 14. It is. And the insertion plug 22 penetrates the mortise 16 and the mortise 18 at the same time, and fixes and fixes them. As shown in FIGS. 5, 6, and 7, in this embodiment, the spigot 22 is integrally provided with insect-proof means 34. The plug body 23 of the plug 22 is made of, for example, an elongated cylindrical wooden rod having an outer diameter substantially the same as the inner diameter of the plug hole 32. The length of the plug 22 is formed to be substantially the same as the depth (length) of the plug hole 32. The plug body 23 may be preliminarily immersed or injected with a liquid insect repellent. The insertion tip portion F of the insertion plug 22 is provided so as to become gradually tapered toward the tip, and the tip drug portion 24 is integrally provided. The insertion base end side end surface of the plug 22 is provided as a flat surface. The plug 22 is loaded so as to be tightly fitted in the plug hole 32 and to almost fill the hole space of the plug hole 32. As a result, the spigot 22 maintains the fitting state of the tenon 16 and the tenon hole 18 across the tenon 16 and the base 14 of the column member 12 and fixes them. In addition, after insertion, the base end surface of the insertion plug 22 becomes substantially flush with the outer side surface 14a of the base 14.

  The plug 22 includes a tip drug part 24 and a guide groove 26. In other words, in the present invention, the bayonet plug 22 is a bayonet plug with an insect repellent function that simultaneously serves as a retaining fixing means for the connecting portion 20 of the first and second structural members and an insect repellent means for realizing the insect repellent effect. I can say that. When constructing an insect repellent structure, a plug hole 32 perpendicular to the tenon 16 and the tenon hole 18 is formed, and the plug 22 is inserted into the plug hole 32 by driving or the like. Can be installed securely.

  The tip drug part 24 is provided on the insertion tip side F of the plug 22 and carries a solid or kneaded insect repellent 36. As shown in FIGS. 6 and 7, the distal drug portion 24 has, for example, an accommodation recess 38 that is recessed from the end on the insertion distal end side F of the plug body 23. The distal drug portion 24 is configured by filling and storing a kneaded insect repellent 36 in the accommodation recess 38. As the insect repellent 36, for example, an insect repellent component that volatilizes at room temperature is used. The insect repellent 36 is made of, for example, a well-known pest repellent that does not attract pests such as termites and bark beetles. Since the insect repellent 36 is installed inside the structural material such as the pillar 12 and the base 14, it is considered that there is little influence of chemical damage to residents in the building room. Therefore, a high insect repellent effect can be expected by using a strong insect repellent agent. The insect repellent 36 may be, for example, a pest control agent that kills pests already invading the structural material. Further, the tip medicine portion 24 may contain and carry a solid insect repellent in a fitting shape in the accommodation recess 38 instead of the kneaded insect repellent.

  The guide groove 26 is a concave groove formed on the outer peripheral surface 22 a of the insertion plug 22, and is formed long from the insertion distal end side F toward the insertion proximal end side R. As shown in FIGS. 4 and 5, in the present embodiment, the guide groove 26 includes, for example, one spiral groove 40 that spirals around the outer peripheral surface. In addition, the groove width and the groove depth are appropriately set as long as the strength of the plug body can be maintained. One end portion on the insertion tip side F of the spiral groove 40 communicates with the housing recess 38 through a communication hole 42 penetrating in the radial direction of the plug 22, that is, penetrating from the outer peripheral surface toward the inside. Therefore, the inside of the accommodation recessed part which accommodated the insect repellent 36 of the front medicine part 24 and the spiral groove 40 (guide groove 26) communicate. The guide groove 26 guides an insect repellent component that volatilizes from the insect repellent 36 of the tip medicine portion 24 to the outer peripheral surface of the plug 22 and allows the insect repellent effect to function over a wide range along the length of the plug 22. it can. Furthermore, in this embodiment, as shown in FIG. 1 and FIG. 2, the spiral groove 40 is filled with a kneaded (or solid) insect repellent 37 before inserting the insert plug in advance ( In addition, in FIG. 4, FIG. 5, etc., the insect repellent 37 is abbreviate | omitted for description. That is, the insect repellent means 34 includes the tip medicine part 24 having the insect repellent 36, the guide groove 26, and the insect repellent 37 filled in the guide groove 26. Therefore, at the initial stage of construction, the insect repellent 37 in the spiral groove 40 directly exhibits an insect repellent effect. Since the amount of the insect repellent 37 that can be held in the spiral groove 40 is small, the insect repellent effect is reduced in a relatively short period of time. However, the insect repellent component is distributed from the distal drug portion 24 carrying a certain amount of the insect repellent 36 through the spiral groove 40. It can be expected to maintain a long-term insect repellent effect. In addition, the guide groove 26 is not limited to the aspect configured by one spiral groove 40, and may be formed by two (or more) spiral grooves 40 as shown in FIG. In addition, the guide groove 26 is not limited to the spiral groove 40, for example, as shown in FIG. 9, the meandering groove 46 formed while meandering along the outer peripheral surface from the insertion distal end F toward the insertion proximal end R. In addition, it may be configured by a linear long groove 44 (see FIG. 10) or the like as in the embodiment described later, or any other groove. Further, the insect repellent 37 may not be filled in the spiral groove 42 in advance. At this time, for example, when a part of the solid or kneaded insect repellent 36 is protruded to the outside from the housing recess 38, and the spigot 22 is driven into the plug hole 32, the part where the insect repellent 36 protrudes. However, it may be guided to be pushed into the guide groove 26 while being sandwiched between the hole wall and the plug body, and the insect repellent may be installed in the guide groove.

  When constructing the insect-proof structure 10 of the wooden building according to the present embodiment, for example, the spigot 22 holding the insect-proofing agents 36 and 37 in advance is prepared. With the tenon 16 of the column 12 and the tenon 18 of the base 14 fitted, a plug hole 32 is formed in a direction orthogonal to the tenon and the tenon with a tool such as a drill. In addition, before fitting, holes may be made in the tenon and base of the column material in advance. Then, the plug 22 is driven into the plug hole 32 with a mallet or the like and inserted. The insect repellent can be installed at a predetermined position simply and surely by a simple and light work such as inserting the plug 22. In the state in which the plug 22 is inserted, almost all the internal space of the plug hole 34 is filled with the plug, and the tenon assembly of the column member 12 and the base 14 is made strong by the plug 22, for example, due to an earthquake or the like The tenon 16 can be prevented from being pulled out of the tenon hole 18, and a high-strength connection structure can be configured. At the same time, the tip tip drug part 24 and the guide groove 26 can exert an insecticidal effect in a wide range over substantially the entire region where the insertion plug 22 is inserted. As a result, termites can be prevented from creeping up from the ground side to the base 14 and the pillar material 12. In particular, since the insect repellents 36 and 37 are installed inside the structural member integrally with the plug 22, it is possible to effectively prevent termites that dislike light and drying from entering the structural material. Therefore, it is possible to realize an earthquake-proof and insect-proof structure with an efficient structure that simultaneously has an improvement in building strength and an insect-proof effect such as termites. Moreover, it is suitable to construct the insect-proof structure 10 of the wooden building for all the connecting portions 20 of the column members, and it is possible to prevent the insect damage more reliably.

  Next, a second embodiment of the insect-proof structure of a building according to the present invention will be described with reference to FIGS. 10 and 11. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The insect-proof structure of the wooden building according to this embodiment has substantially the same configuration as that of the first embodiment, but the configuration of the plug 22a is different. Therefore, in the present embodiment, description will be given mainly of the spigot 22a. As shown in FIGS. 10 and 11, the plug 22 a has a tip drug part 24 and a guide groove 26.

  The distal drug portion 24a is configured, for example, so that a solid insect repellent 36a is supported so as to protrude outward from the distal end of a plug body made of a wooden rod. The insecticidal agent 36a is fixed to the insertion tip side F of the insertion plug by, for example, a method of fixing with an adhesive, a method of fixing with a nail or pin, or a housing recess as in the first embodiment. Any other fixing means such as a structure for fitting a part of the shaped insect repellent may be used.

  The guide groove 26 includes, for example, four long grooves 44 that are formed linearly from the insertion distal end side F to the insertion proximal end side R. In this embodiment, as shown in FIG. 11, the long grooves 44 are arranged at predetermined intervals in the circumferential direction, and are formed, for example, every 90 degrees when the insertion plug 22 is viewed from the distal end side. As shown in FIG. 10, the groove end portion 44 a on the insertion distal end side F of the long groove 44 is formed so as to be cut out toward the distal end side F and open toward the distal end direction. Therefore, the insect repellent component from the insect repellent 36a of the tip medicine portion 24 can be guided into the long groove 44 through the notched groove end portion 44a even in a state where the plug 22 is inserted into the connecting portion 20 of the column member 12 and the base 14. A wide range of insect repellent effects can be expected through the long groove 44. The long groove 44 is provided in a tapered shape that becomes gradually narrower toward the insertion proximal side R. The long grooves 44 may be formed with the same width. In the present embodiment, the long groove 44 is not filled with an insect repellent in advance, but the long groove 44 may be filled with an insect repellent as in the first embodiment. Also, as shown in FIG. 12, in this embodiment as well, the guide groove 26 may be formed by a spiral groove 42 as in the first embodiment. In this case, the groove end portion 42a of the spiral groove 42 is formed so as to open toward the insertion tip side. In the present embodiment, as in the above-described embodiment, it is possible to achieve an effect such as realizing an earthquake-proof and insect-proof structure having an efficient structure that simultaneously has an improvement in building strength and an insect-proof effect such as termites.

  The above-described insect-proof structure of the wooden building of the present invention is not limited to the configuration of the above-described embodiment alone, and can be arbitrarily modified without departing from the essence of the present invention described in the claims of the utility model registration. May be performed.

  The insect-proof structure of the wooden building of the present invention can be suitably applied to a connecting portion of two structural members joined by fitting a tenon and a mortise hole in a wooden building.
