It can be used for 10/20 joining. Alternatively, as shown in FIGS. 6 to 10, it can be used for joining two wooden members 10 and 20 extending in the coaxial direction when manufacturing a long column or beam. Further, as shown in FIG. 11, the joining structure of the two wooden members 10 and 20 and the joining structure of the two wooden members 10 and 20 ′ are connected to join the three wooden members 10, 20, and 20 ′. You can also.

  FIGS. 1 and 2 show a state before joining of the wood member joining structure according to the first embodiment, and FIGS. 3 and 4 show a state after joining.

  In order to construct the joint structure according to the present embodiment, first, as shown in FIGS. 1 and 2, six reinforcing-bar embedding holes 12 are drilled in the joint surface 11 of one wooden member 10, and the other Reinforcing bar embedding holes 22 corresponding to the reinforcing bar embedding holes 12 are drilled in the joint surface 21 of the wooden member 20, and one end 1 a side of one reinforcing bar 1 is provided in each reinforcing bar embedding hole 12. And the other end 1b side of the reinforcing bar 1 is inserted into the reinforcing bar embedded hole 22 corresponding to the reinforcing bar embedded hole 12.

  In FIG. 1, reference numeral 13 denotes an adhesive filling hole that communicates with the end portion 12 b of each reinforcing bar embedding hole 12 of one wooden member 10, and reference numeral 23 in FIG. 1 denotes each of the other wooden member 20. These are adhesive filling holes that communicate with the end portions 22b of the reinforcing bar embedding holes 22, respectively. The adhesive is filled from one of the adhesive filling holes, and the adhesive reaches the other adhesive filling hole. By confirming this, it can be confirmed that the adhesive is filled between the end portion 12 b of the reinforcing bar embedding hole 12 and the end portion 22 b of the reinforcing bar embedding hole 22. In the case of the present embodiment, the adhesive is filled from the upper adhesive filling hole 23 and the arrival of the adhesive to the lower adhesive filling hole 13 is confirmed.

  In the state before joining shown in FIGS. 1 and 2, the porous strip material is spaced from the periphery of each reinforcing bar 1 on the joining surface 11 of one wooden member 10 and inside the periphery of the joining surface 11. 2 is arranged in advance, and the surrounding space 3 is defined around each reinforcing bar 1 by the porous strip 2. In the arrangement of the porous strip 2, if necessary, the porous strip 2 may be fixed by hitting a needle with a tucker, pinning it, or interposing an adhesive.

  Preferably, as shown in FIG. 1, a surrounding space 3 is formed around each reinforcing bar 1 by a porous strip 2, and the surrounding spaces 3 are connected to each other. In other words, the enclosing space 3 is formed by dividing the joint surface 11 of one wooden member 10 into the same number (six in the case of this embodiment) as the number of reinforcing bars 1 to be embedded by the porous strip 2. To do. With this configuration, the porous strip 2 appropriately dams up the adhesive filled through the outer peripheral surface 1c of each reinforcing bar 1, and the damped adhesive is bonded to one joint surface 11 and the other joint surface. Between 21 is filled as much as possible and cured to reinforce the joint strength.

  As shown in FIG. 5 (A), the surrounding spaces 3 are not connected to each other by merely forming the surrounding spaces 3 with the porous strips 2 around the reinforcing bars 1 as shown in FIG. As shown in FIG. 5B, a surrounding space 3 that surrounds all of the plurality of reinforcing bars 1 is formed around the plurality of reinforcing bars 1 by the porous strip 2. In the present embodiment, the configuration is optional depending on the implementation.

  Here, the porous strip 2 will be described in detail. The porous strip 2 is made of a synthetic resin such as polyethylene. As shown in FIGS. 2 and 3, the porous strip 2 is a sponge-like strip having a large number of fine holes formed by foaming of the foam. It has the structure which has the hollow part 2a. Thus, it is preferable that the porous strip 2 has the hollow portion 2a because it can be compressed more thinly in addition to the original porous structure. However, in the present invention, the porous strip 2 does not have the hollow portion 2a. 2 can also be used. Moreover, the cross-sectional shape of the porous strip 2 is not particularly limited, and may be an ellipse or a polygon other than a circle. The porous strip 2 can be compressed to several mm, preferably about 2 mm.

  Moreover, the outer peripheral surface of the porous strip 2 can be coated with a water-resistant material to supplement prevention of leakage of the adhesive. Alternatively, it is possible to prevent leakage while impregnating the adhesive without coating the outer peripheral surface of the porous strip 2 and to integrate it with the cured adhesive (adhesive coating film). .

  After preparing the state before joining as described above, as shown in FIGS. 3 and 4, the joining surface 11 of one wooden member 10 and the joining surface 21 of the other wooden member 20 are abutted and arranged in advance. The compressed strip 2 and the surrounding space 3 are compressed, and the reinforcement reinforcing hole embedding holes 12 of the one wooden member 10 and the other embedding holes 13 and 23 shown in FIGS. If the reinforcing agent embedding holes 22 of the wooden member 20 are filled with the adhesive 4, the compressed porous strip 2 dams the adhesive 4 and leaks from the gap between the joining surface 11 and the joining surface 21. Is appropriately prevented, and the sealed adhesive 4 is also filled in each enclosed space 3.

  Then, the filled adhesive 4 is filled between the inner peripheral surface 12a of each reinforcing bar embedding hole 12 and the outer peripheral surface 1c of the reinforcing bar 1, and the inner peripheral surface 22a of each reinforcing bar embedding hole 22 and the outer peripheral surface 1c of the reinforcing bar 1. If it hardens in between and in each surrounding space 3, the junction structure concerning a present Example can be constructed | assembled.

  Therefore, the porous strip 2 compressed between the joint surface 11 of the one wooden member 10 and the joint surface 21 of the other wooden member 20 does not naturally widen the gap between the joint surface 11 and the joint surface 21. No exposure. Therefore, the leakage of the adhesive 4 through the gap can be appropriately prevented without deteriorating the appearance. In addition, the adhesive 4 that is properly prevented from leaking and hardened can cooperate with each reinforcing bar 1 to firmly join the one wooden member 10 and the other wooden member 20.

  FIGS. 6 and 7 show a state before joining of the wood member joining structure according to the second embodiment, and FIGS. 8 and 9 show states after joining.

  Also in the case of constructing the joint structure according to the present embodiment, as in the first embodiment, first, as shown in FIGS. 6 and 7, six reinforcement reinforcing hole 12 are formed on the joint surface 11 of one wooden member 10. , A reinforcing bar embedding hole 22 corresponding to the reinforcing bar embedding hole 12 is drilled in the joint surface 21 of the other wooden member 20, and one reinforcing bar is provided in each reinforcing bar embedding hole 12. The one end 1a side of the reinforcing bar 1 is inserted, and the other end 1b side of the reinforcing bar 1 is inserted into the reinforcing bar embedding hole 22 corresponding to the reinforcing bar embedding hole 12.

  Further, reference numeral 13 in FIG. 6 denotes an adhesive filling hole communicating with the end portion 12b of each reinforcing bar embedding hole 12 of one wooden member 10, and reference numeral 23 in FIG. These are adhesive filling holes that communicate with the end portions 22b of the reinforcing bar embedding holes 22, respectively. The adhesive is filled from one of the adhesive filling holes, and the adhesive reaches the other adhesive filling hole. By confirming this, it is possible to confirm the completion of filling in both the reinforcing bar embedding hole 12 and the reinforcing bar embedding hole 22.

  This embodiment is different from the first embodiment in that a recess 14 is provided in the joint surface 11 of one wooden member 10 and a reinforcing bar embedding hole 12 is formed in the bottom surface 14a of the recess 14 and the other wooden member 20 is provided. A convex portion 24 fitted to the concave portion 14 is provided on the joint surface 21, and a reinforcing bar embedding hole 22 is formed in the tip surface 24 a of the convex portion 24.

  In the present embodiment, in the state before joining shown in FIGS. 6 and 7, the bottom surface 14 a of the recess 14 provided on the joining surface 11 of one wooden member 10 is porous with a space around each reinforcing bar 1. The strip material 2 is disposed in advance, and the surrounding space 3 is defined around each reinforcing bar 1 by the porous strip material 2.

  Preferably, as shown in FIG. 6, the surrounding space 3 is formed around the reinforcing bars 1 by the porous strip 2 in advance, and the surrounding spaces 3 are continuously provided. In other words, the bottom surface 14a of the recess 14 provided on the joint surface 11 of one wooden member 10 is divided by the porous strip 2 into the same number (six in this embodiment) as the number of reinforcing bars 1 to be embedded. A surrounding space 3 is formed. With this configuration, the porous strip 2 appropriately dams up the adhesive filled through the outer peripheral surface 1c of each reinforcing bar 1, and is as much as possible between the bottom surface 14a of the concave portion 14 and the front end surface 24a of the convex portion 24. The adhesive strength is strengthened by filling and curing the adhesive extensively.

  In addition, about the surrounding space 3, as shown to FIG. 10 (A), it is set as the structure which does not mutually connect each surrounding space 3 only by forming the surrounding space 3 around each reinforcing bar 1, respectively. As shown in FIG. 10 (B), the porous strip 2 may be configured to form a surrounding space 3 surrounding the plurality of reinforcing bars 1 around the plurality of reinforcing bars 1. Also in an Example, it is arbitrary according to implementation.

  Moreover, since it is the same as that of Example 1 about porous strip 2 itself, description of the porous strip 2 in Example 1 is used here. Also in the present embodiment, the porous strip 2 may be fixed by placing a needle with a tucker, pinning it, or interposing an adhesive, as necessary. Of course.

  After preparing the state before joining as described above, the joining surface 11 of one wooden member 10 and the joining surface 21 of the other wooden member 20 are abutted as shown in FIGS. One of the wooden members is fitted through the adhesive filling holes 13 and 23 shown in FIGS. 6 and 9 by fitting the portion 24 and compressing the preliminarily disposed porous strip 2 and the surrounding space 3. If the adhesive 4 is filled in each of the reinforcing bar burying holes 12 and the reinforcing bar burying holes 22 of the other wooden member 20, the compressed porous strip 2 dams the adhesive 4 and joins the bonding surface. 11 and the joint surface 21 are appropriately prevented from leaking, and the dammed adhesive 4 is also filled in each enclosed space 3.

  Then, the filled adhesive 4 is filled between the inner peripheral surface 12a of each reinforcing bar embedding hole 12 and the outer peripheral surface 1c of the reinforcing bar 1, and the inner peripheral surface 22a of each reinforcing bar embedding hole 22 and the outer peripheral surface 1c of the reinforcing bar 1. If it hardens in between and in each surrounding space 3, the junction structure concerning a present Example can be constructed | assembled.

  Therefore, the porous strip 2 compressed between the bottom surface 14a of the concave portion 14 in the joint surface 11 of the one wooden member 10 and the tip end surface 24a of the convex portion 24 in the joint surface 21 of the other wooden member 20 is the joint surface 11. In addition, the gap between the joint surfaces 21 is not widened and is not exposed. Therefore, the leakage of the adhesive 4 through the gap can be appropriately prevented without deteriorating the appearance.

  Particularly in this embodiment, the fitting between the concave portion 14 and the convex portion 24 absorbs the thickness of the compressed porous strip material 2 while concealing the porous strip material 2 to ensure the appearance, The leakage of the adhesive 4 can be secondarily prevented. In addition, the structure regarding the recessed part 14 and the convex part 24 shown in the present Example can naturally be extracted also for joining of wooden members having different axial directions exemplified in Example 1.

  Also in the present embodiment, the adhesive 4 that has been properly prevented from leaking and hardened can cooperate with each reinforcing bar 1 to firmly join the one wooden member 10 and the other wooden member 20. In addition, the shearing force can be reinforced by fitting the concave portion 14 of one wooden member 10 and the convex portion 24 of the other wooden member 20.

  As shown in FIG. 11, the joining structure according to the present embodiment is obtained by joining a wooden member 20 and a wooden member 20 'to the left and right sides of a wooden member 10 in which the axial direction of a pillar or the like is vertical. Although the members 10, 20, and 20 ′ are joined together, the joined structure of the pair of wooden members 10, 20 and the joined structure of the pair of wooden members 10, 20 ′ are continuously configured. . That is, two joint structures are made continuous through a common reinforcing bar 1.

  In order to construct the joint structure according to the present embodiment, first, the concave portion 14 is provided on the joint surface 11 on the right side surface of the central wooden member 10, and the concave portion 14 'is provided on the joint surface 11' on the left side surface. Two reinforcing-bar embedding holes 12 penetrating between the bottom surface 14a of the recess 14 and the bottom surface 14'a of the recess 14 'are formed. Further, a convex portion 24 fitted to the concave portion 14 is provided on the joint surface 21 of the wooden member 20 joined from the right side, and two reinforcing bars corresponding to the reinforcing bar embedding hole 12 are provided on the tip surface 24a of the convex portion 24. The embedding hole 22 is drilled, and a convex portion 24 ′ that fits the concave portion 14 ′ is provided on the joint surface 21 ′ of the wooden member 20 ′ joined from the left side. Two reinforcing bar embedding holes 22 ′ corresponding to the reinforcing bar embedding holes 12 are formed.

  Next, the two reinforcing bars 1 are respectively inserted into the reinforcing bar embedding holes 12 of the wooden member 10, and one end portions of the reinforcing bars 1 are respectively inserted into the reinforcing bar embedding holes 22 of the wooden member 20. The other end side is inserted into the reinforcement reinforcing hole 22 'of the wooden member 20'.

  Also in the present embodiment, as in the first and second embodiments, the porous strip 2 is disposed in advance on the bottom surface 14a of the recess 14 and the bottom surface 14'a of the recess 14 'so as to surround the space 3 Is formed. The configuration and arrangement pattern of the porous strip 2 itself are the same as those in the first and second embodiments. However, in FIG. 11, the porous strip 2 has two reinforcing bars 1 around the two reinforcing bars 1. It is depicted as an arrangement pattern of a configuration that forms an enclosed space 3 that surrounds all of the reinforcing bars 1 of the book. Further, in the arrangement of the porous strip 2, it may be fixed as necessary by hitting a needle with a tucker, pinning, or interposing an adhesive as necessary. It is the same.

  Then, the joint surface 11 of the wooden member 10 and the joint surface 21 of the wooden member 20 are abutted and the concave portion 14 and the convex portion 24 are fitted, and the bottom surface 14a of the concave portion 14 and the front end surface 24a of the convex portion 24 are arranged in advance. The porous strip 2 and the enclosed space 3 are compressed. Further, the joining surface 11 ′ of the wooden member 10 and the joining surface 21 ′ of the wooden member 20 ′ are butted to fit the recess 14 ′ and the projection 24 ′, so that the bottom 14 ′ a and the projection 24 of the recess 14 ′ are fitted. The porous strip 2 and the surrounding space 3 previously disposed on the tip surface 24′a of ′ are compressed.

  Finally, an adhesive filling hole 23 communicating with the end portion 22b of the reinforcing bar embedding hole 22 of the wooden member 20 and an adhesion communicating with the end portion 22'b of the reinforcing bar embedding hole 22 'of the wooden member 20'. The adhesive 4 is filled from one side of the agent filling hole 23 ′ to the other side.

  When the adhesive 4 is filled, the porous strip 2 compressed between the bottom surface 14 a of the concave portion 14 and the tip surface 24 a of the convex portion 24 blocks the adhesive 4 and leaks from the gap between the joint surface 11 and the joint surface 21. The adhesive 4 that has been dammed is appropriately filled in the enclosed space 3 while being appropriately prevented from coming out. Similarly, the porous strip 2 compressed between the bottom surface 14 ′ a of the recess 14 ′ and the tip surface 24 ′ a of the projection 24 ′ blocks the adhesive 4, and between the joint surface 11 ′ and the joint surface 21 ′. While appropriately preventing leakage from the gap, the sealed adhesive 4 is also filled in each enclosed space 3.

  Therefore, the porous strip 2 compressed between the bottom surface 14 a of the concave portion 14 in the joint surface 11 of the wooden member 10 and the tip end surface 24 a of the convex portion 24 in the joint surface 21 of the wooden member 20 is the joint surface 11 and the joint surface 21. It does not expose the gaps between them. Similarly, the porous strip 2 compressed between the bottom surface 14'a of the recess 14 'in the joint surface 11' of the wooden member 10 and the tip surface 24'a of the convex portion 24 'in the joint surface 21' of the wooden member 20 '. However, the gap between the joint surface 11 'and the joint surface 21' is not increased without any exposure. Therefore, the leakage of the adhesive 4 can be appropriately prevented without impairing the appearance.

  Also in the present embodiment, as in the second embodiment, the compressed porous strip 2 is compressed by fitting the concave portion 14 and the convex portion 24 and fitting the concave portion 14 'and the convex portion 24'. While absorbing the thickness, the porous strip 2 can be concealed to ensure appearance, and the adhesive 4 can be prevented from leaking secondarily.

  Therefore, also in the present embodiment, the adhesive 4 which is properly prevented from leaking and hardened cooperates with the reinforcing bars 1 to firmly join the three members of the wooden member 10, the wooden member 20 and the wooden member 20 ′. It becomes the structure. In addition, the shearing force can be reinforced by fitting the concave portion 14 and the convex portion 24 and fitting the concave portion 14 'and the convex portion 24'.

  As described above, the wood member joining structure according to the present invention has the reinforcement reinforcement embedding holes 12 and 22 drilled in the joint surfaces 11 and 21 (21 ') of the wood members 10 and 20 (20'), respectively. 22 '), between the reinforcing bars 1 inserted into the respective reinforcing bar embedding holes 12 and 22 (22') and the joint surfaces 11 and 21 (21 ') of the pair of wooden members 10 and 20 (20'). A compressed porous strip 2 and an enclosed space 3 formed by the compressed porous strip 2 are provided, between the outer peripheral surface 1c of the reinforcing bar 1 and the reinforcing bar embedding hole 12a, and the outer peripheral surface of the reinforcing bar 1. One of the wooden members cooperates with the reinforcing bar 1 by the adhesive 4 filled and cured between 1c and the inner peripheral surface 22a (22'a) of the reinforcing bar embedding hole 22 (22 ') and each surrounding space 3. 10 and the other wooden member 20 (20 ').

  Therefore, while the porous strip 2 that has compressed the leakage of the adhesive 4 from the gap between the joint surfaces 11 and 21 (21 ') of the pair of wooden members 10 and 20 (20') appropriately prevents the The porous strip 2 is not exposed and does not unnecessarily widen the gap between the joint surfaces 11 and 21 (21 ') of the pair of wooden members 10 and 20 (20'). Therefore, a strong joint structure can be constructed without impairing the appearance.
