Description

  The present invention relates to a wooden member joining apparatus in a building that can firmly and firmly join wooden members in a building.

  When joining horizontal members such as beams, girder, girders, etc., or joining these horizontal members and columns in a wooden building, for example, as shown in FIGS. 39 to 40 and FIGS. In addition, the joint portion between the horizontal members a and a and the joint portion between the horizontal member a and the column b are reinforced using a feather plate bolt e in which a tension bolt d is fixed to the feather plate c.

  If this reinforcing structure is described in the case of reinforcing the joint portion between the horizontal members a and a, as shown in FIG. 40, the tension bolt d of the battledore bolt e is provided on one horizontal member a1. The nut is inserted through the through-hole f, the abutment plate c is brought into contact with the side surface h of the end portion g of the other horizontal member a2, and the bolt k is inserted into the bolt fixing hole j provided in the end plate c. By tightening with m and nailing v into the nail insertion hole u, the wing plate c is fixed to the horizontal member a2, and the nut q is screwed to the end portion n of the tension bolt d via the washer p. It was done by tightening. As shown in FIG. 42, this was the same when reinforcing the joint between the horizontal member a and the column b.

  However, there are the following problems when using the reinforcing structure using the battledore bolt e. That is,

(1) In recent wooden construction styles, the joints such as the blowout structure that impresses the texture of the wood with the joints between the horizontal members and the joints between the horizontal members and the pillars exposed. It is popular to adopt a structure that makes it visible.
In such a structure, since the joint portions such as the horizontal members are exposed, the above-mentioned battledore bolts are conspicuous and the appearance of the joint portions is unnatural.

 (2) In addition, when fixing the battledore bolt e to the horizontal member a, a means for inserting a bolt k or the like into the bolt fixing hole j provided in the thin battledore c having a thickness of about 3 to 4 mm is used. Therefore, in the event of a large earthquake, for example, as shown in FIG. 43, stress concentrates at the point-like contact portion s between the peripheral edge r of the bolt fixing hole j and the bolt k and the like, and there is a risk of cracks occurring at the peripheral edge r. was there. When cracks are generated in this way, the cracks gradually expand, and the fixing of the battledore c to the horizontal member a is likely to be unstable, and the reinforcing effect by the battledore bolt e is not effectively exhibited.

(3) Furthermore, as shown in FIGS. 39 and 41, since the battledore c and the tension bolt d are in a protruding state on the surface of the horizontal member a, another member is attached to the portion where the battledore bolt e is fixed. When attaching, there was also the troublesomeness which had to provide the notch part for letting a wing board and a tension bolt escape to this member.

 (3) In particular, the housing hole is formed as a through hole, and in the state where the rod-shaped fixing member is housed in the housing hole, a recess is formed at both end portions of the housing hole, and the inside of the plug body is formed in the recess. When the part is fixed and the outer part of the plug body is projected from the side surface of the second member, the rod-like fixing member and the screw shaft member are almost built in the first member and the second member as described above. In combination with this, it is preferable that the joint portion between members can be made to look like an architectural style of a traditional plug-in joint.

 (4) When the accommodation hole is configured as a through-hole, when the rod-like fixing member is accommodated in the accommodation hole, the accommodation state of the rod-like fixing member can be confirmed from both ends of the accommodation hole, and the rod-like fixing member is inserted through the opening end. Since it can be pushed with a finger or the like, the required accommodating operation of the rod-shaped fixing member can be performed more easily.

 (5) In the joining device according to the present invention, when joining the first member and the second member has a tenon joining structure, the tenth through hole through which the screw shaft is inserted and the tenth hole communicating therewith are When forming by avoiding the joining portion, the first member and the second member can be joined using the screw shaft member and the rod-like fixing member without damaging the tenon joining structure portion. As a result of obtaining such two types of joining, the joining of the first member and the second member can be performed more firmly and stably.

 (6) When the rod-shaped fixing member is formed to have a square cross section so as to have a flat pressing surface, the pressed surface of the receiving hole can be pressed over a wide area by the rod-shaped fixing member. Can be attracted more stably toward the first member.

  Hereinafter, an embodiment of the present invention will be described by taking as an example a case where the present invention is applied to a wooden blowout structure in which a ceiling plate is not stretched and a joint portion between members is exposed.

  1 to 3, a joining apparatus 1 according to the present invention includes a wooden first member (for example, a horizontal beam) 2 as a building beam, a trunk, a girder, and the like, and is obliquely upward with respect to the first member 2. The second member 3 that is inclined and dropped and joined is joined using the screw shaft member 5 and the rod-like fixing member 6. The first member 2 and the second member 3 are made of wood such as cedar, bamboo shoots, rice pine, laminated timber and the like generally used in wooden buildings.

  As shown in FIGS. 2 to 5, the first member 2 is provided with a receiving surface 10 for fitting the lower end portion 7 in the inclined direction of the second member 3 and supporting the bottom surface 9 of the lower end portion 7 from below. The recessed part 11 by which the upper end and the front surface were open | released was provided. And the groove | channel 13 as an up-and-down dovetail groove | channel with the upper end open | released is provided in the center of the upper part (substantially upper half) of the smooth standing wall surface 12 of this recessed part 11, The bottom face of this groove | channel 13 An insertion hole 16 that is positioned below the armpit 15 and through which the screw shaft member 5 is inserted is provided through the first member 2 in the thickness direction. In addition, the surrounding part of the outer end of the said insertion hole 16 of this 1st member 2 is formed as the circular recessed part 17 for accommodating the screw head 37 mentioned later, as shown in FIGS. 1-3 and FIG.

  As shown in FIGS. 1 to 3, the second member 3 has a tenon 20 projecting from the lower end surface 19 in the inclined direction, and covers the upper end of the tenon 20 as the ant tenon. A flange 22 covering the upper surface 21 of the first member 2 is projected. Then, in a state where the tenon 20 is fitted into the groove 13, the bottom surface 9 of the lower end portion 7 of the second member 3 is supported from below by the receiving surface 10 of the recess 11 as shown in FIG. At the same time, the lower surface 25 of the flange piece 22 contacts the upper surface 21 of the first member 2.

  Further, the lower end surface 19 of the second member 3 is blindly connected to the insertion hole 16 in a state where the tenon 20 is fitted in the groove 13 as shown in FIGS. An insertion hole 26 is provided immediately below the tenon 20. A receiving hole 27 having a square cross section for loosely inserting the rod-shaped fixing member 6 having a square cross section having a square cross section as shown in FIG. 3 is close to the tenon 20 on the distal end side of the insertion hole 26. A pressed surface 29 is provided so as to intersect the insertion hole 26 at a right angle, and a protruding portion of the insertion hole 26 from the accommodation hole 27 is a relief hole 30. The accommodation hole 27 is provided, for example, at a position away from the lower end surface 19 of the second member 3 by about 120 to 150 mm. The length of the escape hole 30 is normally 10 to 15 mm so that the tapered tip portion 31 of the screw shaft member 5 (a portion having a length of about 5 mm in this embodiment) can be released. Sometimes it is set to about 20 mm with a margin.

  The rod-shaped fixing member 6 is made of metal such as steel or stainless steel, for example, as shown in FIG. 6, at the substantially central portion in the length direction of the pressing surface 28 that contacts the pressed surface 29. A screw hole 33 is provided through which the screw shaft portion 32 on the front side of the screw shaft member 5 is threadedly engaged, and the end on which the screw shaft portion 32 is inserted faces the end (the pressing surface). A tapered guide hole 35 whose diameter is increased is provided continuously. The tapered tip portion 31 of the screw shaft member 5 is located in the escape hole 30 in a state where the screw shaft portion 32 is screwed into the screw hole 33 and tightened. In the present embodiment, the front side portion of the screw shaft portion 32 is also positioned in the escape hole 30.

  In the present embodiment, the thickness of the second member 3 is 112 mm, and therefore the length of the receiving hole 27 is 112 mm. On the other hand, the length of the rod-shaped fixing member 6 is set to 100 mm. The length of the screw hole 33 is set to about 16 mm. The length of one side of the accommodation hole 27 is set to 21 mm, for example, and the length of one side of the rod-shaped fixing member 6 is set to 20 mm, for example, so that the rod-like fixing member 6 is loosely inserted into the accommodation hole 27. be able to.

  Further, as shown in FIG. 5, the screw shaft member 5 has a screw head 37 at the base end of the screw shaft 36 having a length of, for example, about 30 cm and a diameter of about 12 mm. The distal end side is formed as a screw shaft portion 32, and the distal end portion 31 is tapered.

  However, in order to join the first member 2 and the second member 3 using the joining device 1 having a three-piece structure, the lower end 39 (FIG. 3) of the tenon 20 is connected to the upper end 40 (FIG. 3) of the groove 13. ) And the second member 3 is dropped, and the bottom surface 9 of the lower end portion 7 of the second member 3 is brought into contact with the receiving surface 10 of the recess 11 as shown in FIG. The lower surface 25 of the piece 22 is brought into contact with the upper surface 21 of the first member 2. Thereafter, as shown in FIG. 7, the rod-like fixing member 6 is inserted into the accommodation hole 27 with the guide hole 35 facing the pressed surface 29. This insertion is performed so that the screw hole 33 is substantially in communication with the insertion hole 26. Since the accommodation hole 27 and the rod-shaped fixing member 6 have a square cross section, the rod-shaped fixing member 6 does not rotate around the axis in the accommodation hole 27. In this embodiment, since both ends of the accommodation hole 27 are open, the length of the space at both ends of the accommodation hole 27 is reduced by pressing the rod-like fixing member 6 with a finger or the like through the open ends 41, 41. If they are set equal, the screw hole 33 is positioned at substantially the center in the length direction of the accommodation hole 27, so that the operation of arranging the rod-like fixing member 6 in the accommodation hole 27 is facilitated.

  Thereafter, as shown in FIG. 2, the screw shaft portion 32 of the screw shaft member 5 is inserted into the insertion hole 16 and the insertion hole 26 from the circular recess 17 side through a washer 42, and the screw shaft portion. 32 is screwed into the screw hole 33.

  At the time of this screwing, the tip end portion 31 of the screw shaft member 5 is tapered, and a tapered guide hole 35 is continuously provided at the end of the screw hole 33, and the rod-like fixing member is provided in the accommodation hole 27. 6 is loosely inserted, even if the axis of the screw shaft portion 32 to be inserted does not exactly match the axis of the screw hole 33, as shown in FIG. As long as the tapered tip 31 enters the guide hole 35, the rod-shaped fixing member 6 moves in the length direction of the receiving hole 27 as the screw shaft member 5 is pushed, and the screw shaft portion 32 is moved. The screw hole 33 is correctly screwed. When the screw shaft member 5 is further rotated in the screwing direction in this state, the tapered tip portion 31 protrudes from the end portion of the screw hole 33 and is received in the escape hole portion 30 as shown in FIG. When the screw shaft member 5 is tightened in this state, the rod-shaped fixing member 6 is drawn toward the first member 2, whereby the entire pressing surface 28 of the rod-shaped fixing member 6 is pressed against the pressed surface 29 of the receiving hole 27. Is pressed in a surface contact state, and the first member 2 and the second member 3 can be firmly joined as shown in FIG. Since the tapered tip portion 31 of the screw shaft member 5 can be positioned in the escape hole 30, the screw shaft portion 32 can be effectively screwed over the entire length of the screw hole 33. In the joined state as shown in FIG. 2, the screw head 37 of the screw shaft member is accommodated in the circular hole portion 17.

  In this way, the pressing surface 28 of the rod-shaped fixing member 6 presses the pressed surface 29 orthogonal to the axis of the screw shaft member 5 in a surface contact state. The joining with the two members 3 is further strengthened by screwing the screw shaft member 5.

  In the present embodiment, the first member 2 and the second member 3 are joined by two types: a tenon joint structure and a joint structure by the screw shaft member 5 and the rod-shaped fixing member 6. The joining with the two members 3 can be performed more reliably and more stably.

  And since the said rod-shaped fixing member 6 and the said screw shaft member 5 are incorporated in the 1st member 2 or the 2nd member 3 in the state joined in this way, joining of the 1st member 2 and the 2nd member 3 is carried out. Since the bar-shaped fixing member 6 and the screw shaft member 5 are not exposed in the appearance of the portion, the appearance of the joint portion can be improved.

  In the joined state, as shown in FIG. 9, recesses 45, 45 having a depth of about 6 mm are formed on both ends of the accommodation hole 27. Therefore, in the present embodiment, as shown in FIG. 10, the plug body 46 is press-fitted into the recesses 45, 45 and the front side portion 47 is, for example, 9 mm from the left and right side surfaces 49, 49 of the first member 2. It protrudes to a certain extent.

  In this way, when the plug body 46 is protruded from the left and right side surfaces 49 so as to look up at the joint portion between the first member 2 and the second member 3, the left and right plug bodies 46, Because 46 is visible, it can give the appearance as if adopting the traditional technique of wooden frame structure, which is made by joining the two members by driving in the plug, further improving the appearance of the joint part Can do.
