  The beam member 16 has a straight insertion hole 17 extending from the one end surface 16a to the end surface in the extending direction of the mounting hole 12 in a horizontal and perpendicular direction. The insertion hole 17 has the same inner diameter as that of the accommodation hole 13 and is connected. A locking hole 18 is formed at a predetermined position on the vertical side surface 16b of the beam member 16 and passes through the beam member 16 through the insertion hole 17 in a direction perpendicular to the surface and in the horizontal direction. A pipe member 21 is inserted into the insertion hole 17, and a pin member 29 is inserted into the locking hole 18.

  As shown in FIGS. 4 and 5, the pipe member 21 is coaxially fitted into the shaft hole 22b at the one end side 22a (the left end in the figure) in a straight cylindrical cylindrical body 22 and its axial direction. And a sealing portion 25 which is a cylindrical thick plate fixed. The cylindrical main body 22 is provided with a pair of long oblong engagement holes 23 that penetrate in the direction perpendicular to the axis and are long in the axial direction at a position close to the other end side in the axial direction (the right end in the figure). The engagement long holes 23 are provided on both sides in the radial direction by drilling the cylindrical main body 22 so that the outer peripheral edge is slightly recessed from the outer peripheral surface. In the sealing portion 25, the inner diameter of the insertion hole 25 a provided in the shaft center is slightly larger than the outer diameter of the bolt member 31. In addition, the sealing part 25 may be integrally formed in the process of the cylindrical main body 22 instead of another member.

  The pipe member 21 has a sealing portion 25 inserted into the cylindrical main body 22 from one end side in the axial direction, the one end side slightly protrudes from one end side of the cylindrical main body 22, and the outer periphery of the protruding portion is located on the cylindrical main body 22. It is formed by fixing to one end with a weld 26. In the shaft hole 22b of the pipe member 21, a mounting plate 27 that is a circular thick plate is inserted coaxially inward in the axial direction from the engagement long hole 23. The mounting plate 27 has an outer diameter substantially the same as that of the shaft hole 22b, has a screw hole 27a at the center, and can slide within the shaft hole 22b.

The pin member 29 is cylindrical, has one end side provided with a thread groove on the outer peripheral surface, and has an oval cross-sectional shape in which the one end side 29a is slightly crushed in one radial direction. The bolt member 31 has a hexagonal head 32 at one end, and is provided with a screw portion 33 in a predetermined range on the other end side.

  Next, formation of the joining structure of the beam member 11 and the beam member 16 will be described. The pipe member 21 into which the coil spring 28 and the mounting plate 27 are inserted is slidably inserted into the insertion hole 17 of the beam member 16 from the other end side, and a rod-shaped pin member 29 is provided on the side surface of the beam member 16. It is inserted into the locking hole 18, passes through the engagement long hole 23, and is fixed to the beam member 16. Thereby, the pipe member 21 is restrained by the pin member 29 engaged with the engagement long hole 23, and can be slid in the longitudinal direction within the length range of the engagement long hole 23. It becomes the state accommodated in. Thereafter, the bolt member 31 is inserted from the opposite surface 11b side into the mounting hole 12 of the beam member 11 on which the beam members 16 are overlapped, and the head portion 32 is engaged with the opposite surface 11b via the washer 34, thereby sealing the sealing portion. The tip screw portion 33 is screwed into the screw hole 27 a of the mounting plate 27 through the 25 insertion holes 25 a and the coil spring 28. As a result, the coil spring 28 is compressed, the pipe member 21 is pulled, and one end thereof is accommodated in the accommodation hole 13.

  Regarding the joining structure of the beam member 11 and the beam member 16, in the first embodiment, as a preferred use example, as shown in FIGS. The connecting devices 20A to 20C are used for the stage. As described above, it is preferable that the connection device is used in three or more stages. However, the connection apparatus may be used in two stages. In some cases, it may be used alone.

  In the first embodiment, the bolt member 31 is inserted into the attachment hole 12 of the beam member 11 from the opposite surface 11 b side, and the screw portion 33 is screwed into the screw hole 27 a of the attachment plate 27 in the pipe member 21. As a result, one end side of the pipe member 21 is pulled into the accommodation hole 13, and a joining structure of the beam member 11 and the beam member 16 is formed. The strength in the pulling direction at the joint surface between the beam member 11 and the beam member 16 is ensured by the tensile force between the pipe member 21 and the bolt member 31 via the coil spring 28. Furthermore, since one end side of the pipe member 21 is arranged in a state of straddling the joining surface of the beam member 11 and the beam member 16, the strength in the shear direction between the members 11 and 16 is also supported by the pipe member 21. Sufficiently secured. As a result, in the first embodiment, a sufficiently strong joint structure for joining the beam member 11 and the beam member 16 is obtained.

  Furthermore, in Example 1, when a lateral vibration is applied to the joint structure due to a large earthquake such as an earthquake, a force for separating the beam member 11 and the beam member 16 acts. At that time, as shown in FIG. 7, for example, with the lower connecting device 20C as a fulcrum, the bolt member 31 is pulled in the horizontal direction in the upper connecting devices 20B and 20A, and the mounting plate 27 compresses the coil spring 28. The lower upper connection devices 20B and 20C can be reversibly displaced with the upper connection device 20A as a fulcrum. As a result, in the first embodiment, since the vibration can be absorbed by the elastic deformation of the coil spring 28, the vibration control function that suppresses the damage to the building can be effectively exhibited. Moreover, since this joining structure can arrange | position the some joining apparatus 20 in many places of a building, the effect which improves the damping function of the whole building is acquired. Furthermore, since this joining structure can be constructed inexpensively and easily by the pipe member 21, the mounting plate 27, the coil spring 28, the pin member 29, the bolt member 31, and the like, it can be realized at a lower cost than the conventional vibration control device. . The joining device 20 has a seismic control function that suppresses vibrations such as earthquakes applied to the building, in addition to the joining function of firmly joining the beam member 11 and the beam member 16 superimposed in a T shape. It is suitably provided as an inexpensive and highly functional member.

  In the first embodiment, as a modification of the coil spring 28, an elastic member 28A made of a cylindrical urethane resin that can be elastically deformed as shown in FIG. 8 can be used. Since the elastic member 28A can be mass-produced by injection molding of urethane resin, the member price is significantly reduced compared to the coil spring. Further, instead of the urethane resin, a rubber elastic body or other elastic body elastomer can be used.

  Next, Example 2 will be described. FIG. 9 is a front sectional view showing a seismic control joint structure in which a beam member and a beam member according to the second embodiment are joined. FIG. 10 is a perspective view of a known joint body used for joining the joints of wooden members, and FIG. 11 is an exploded perspective view of the joint relationship between the beam member 11, the beam member 36, and the joint body 51. This is shown in the figure.

A cylindrical attachment member 45 is slidably inserted into the shaft hole 42a in the shaft hole 42a on the other end side of the cylindrical main body 42. The attachment member 45 is formed by fixing a nut 47 having a screw hole to a circular thin plate 46 having a center hole, and the bolt member 31 can be screwed into the screw hole of the nut 47. A coil spring 48 that is an elastic member having substantially the same diameter as the inner diameter of the shaft hole 42 a is inserted into the shaft hole 42 a of the pipe member 41, and is sandwiched between the sealing portion 43 and the attachment member 45. The bolt member 31 has a hexagonal head 32 at one end, and is provided with a screw portion 33 in a predetermined range on the other end side.

  As shown in FIG. 10, the joint body 51 is a vertically long member formed in a U shape by bending a rectangular metal thin plate formed by pressing, and an intermediate joint portion 52. It is constituted by a pair of joint portions 54 provided at right angles on both sides and facing each other. Three insertion holes 53 are formed in the joint portion 52 so as to be separated from each other in the vertical direction. The diameter of the insertion hole 53 is the same as the diameter of the accommodation hole 13 provided in the beam member 11. Both joint portions 54 are provided with a pair of cutout portions 55 that are fixing holes in the upper and lower portions opposite to the joint portion 52. The notch 55 has a predetermined width perpendicular to the upper and lower ends and has a semicircular tip, and an inclined edge 55a that is notched so that the opposite side portion extends toward the upper and lower ends. It has become. A pair of upper and lower fixing holes 56 is provided between the upper and lower cutout portions 55. The notch 55 and the fixing hole 56 fix the joint portion 37 of the beam member 36 to the joint device main body 51 by fitting the pin member 57 together. In addition, although the junction part 52 is a flat plate, the shape swelled in the circular arc shape outward from both joint parts may be sufficient.

  The joint body 51 has substantially the same vertical length as that of the beam member 36, and the tubular body 42 of the pipe member 41 is inserted into the insertion hole 53 of the joint portion 52. The other end is slightly fixed from the insertion hole 53 and is fixed to the inner surface of the joint 52 by welding 52a. In the state where the coil spring 48 and the attachment member 45 are inserted into the welded pipe member 41, the joint body 51 is aligned with the one side surface 11 a of the beam member 11 and is opposite to the beam member 11. The screw member 33 on the front end side of the bolt member 31 inserted from the side of the surface 11b is screwed into the screw hole of the mounting member 45 inserted on the other end side of the pipe member 41 and tightened, whereby the beam member is interposed via the coil spring 48. 11 is fixed in a close contact state.

  Next, formation of the joining structure of the beam member 11 and the beam member 36 will be described. A projecting portion of the pipe member 41 that protrudes outward from the joint portion 52 of the pipe member 41 that is fixed to the insertion hole 53 of the joint portion 52 of the joint body 51 is inserted into the accommodation hole portion 13 of the beam member 11. The screw hole of the mounting member 45 in which the head portion 32 of the bolt member 31 inserted from the opposite surface 11 b side of the beam member 11 is engaged with the opposite surface 11 b and the screw portion 33 on the distal end side is inserted on the other end side of the pipe member 41. The joint body 51 is firmly fixed in close contact with the joint surface of the beam member 11 via the coil spring 48 by being screwed onto and tightened. In this way, the beam member 36 in which the pin member 57 is inserted into the locking hole 38 at the upper end is dropped from the upper side with respect to the joint body 51 fixed to the joining surface of the beam member 11, so The longitudinal groove portion 37a is inserted into both joint portions 54, and the pin member 57 is fitted into the notch portion 55 along the inclined edge portion 55a of the joint portion 54, whereby the joint portion 37 of the beam member 36 is joined. It is attached to the main body 51.

  Further, the beam member 36 is joined to the beam member 11 by press-fitting the pin member 57 into the two fixing holes 56 and the notch portion 55 at the lower end provided in the joint portions 54 through the three locking holes 38. It is fixed tightly via the tool body 51. In the second embodiment, as a preferred example of use, as shown in FIG. 12, connecting devices 40 </ b> A to 40 </ b> C are used in the upper and lower three stages for the beam member 11 and the beam member 36. As described above, it is preferable that the connection device is used in three or more stages. However, the connection apparatus may be used in two stages. In some cases, it may be used alone.

  In the second embodiment, the strength in the pulling direction of the beam member 11 and the beam member 36 can be ensured by the tensile force between the pipe member 41 and the bolt member 31 via the coil spring 48. Since it is inserted in the accommodation hole portion 13 of the material 11 and is disposed across the joining surface of the beam material 11 and the beam material 36, the strength in the shear direction between them is also determined by the pipe member 41. It is supported and secured sufficiently.

  Further, in Example 2, when a lateral vibration is applied to the joint structure due to a large earthquake such as an earthquake, a force that separates the beam member 11 and the beam member 36 acts. In this case, in FIG. As shown, for example, with the lower connection device 40C as a fulcrum, the bolt member 31 is pulled in the horizontal direction in the upper connection devices 40B and 40A, and the mounting member 45 can be reversibly displaced while compressing the coil spring 48, On the contrary, with the upper connecting device 40A as a fulcrum, the lower upper connecting devices 40B and 40C can be reversibly displaced. As a result, also in the second embodiment, since the vibration can be absorbed by the elastic deformation of the coil spring 48, the vibration control function that suppresses damage to the building can be effectively exhibited. Moreover, also in Example 2, since the joining structure can arrange | position the several joining apparatus 40 in many places of a building similarly to Example 1, the effect which improves the damping function of the whole building is acquired, Furthermore, since the joining structure can be easily and inexpensively constructed by the pipe member 41, the mounting member 45, the coil spring 48, the bolt member 31, and the like, it is provided at a lower cost than conventional vibration control devices. Further, the joining device 40 has a seismic control function that suppresses vibrations such as earthquakes applied to the building, in addition to a joining function for firmly joining the beam member 11 and the beam member 36 superimposed in a T shape. It is suitably provided as an inexpensive and highly functional member.

  Next, a modification of the second embodiment will be described. As shown in FIG. 13, in the modification, a cylindrical pipe portion 61 is formed at the position of the insertion hole 53 of the joint portion 52 by processing the joint body 51 </ b> A without using a separate pipe member for the joint device 40 </ b> X.

Further, the head 32 of the bolt member 31 inserted from the opposite surface 11 b side of the beam member 11 is engaged with the opposite surface 11 b and the screw portion 33 on the distal end side is disposed on the other end side of the pipe portion 61. The joint body 51 </ b> A is firmly fixed to the joint surface of the beam member 11 through the coil spring 65 in a close contact state. As shown in the second embodiment, the joint portion 37 of the beam member 36 is attached to the joint body 51A fixed to the joint surface of the beam member 11, and the joint portions 54 are further provided. By pressing the pin member 57 into the two notches 55 and the fixing hole 56, the beam member 36 is tightly fixed to the beam member 11 via the joint body 51. As a result, the same effects as those of the second embodiment can be obtained in the modified example. Moreover, since it is not necessary for the joining apparatus 40X to prepare the pipe portion 61 separately from the joint body 51A, the member cost is reduced. Furthermore, since the degree of protrusion of the pipe portion 61 toward the joint body 51A can be reduced, the influence on the joint portion 37 can be reduced. In the second embodiment and the modified example, it is possible to use an elastically deformable cylindrical urethane resin or a rubber material instead of the coil spring 28 as the elastic member.

Is done. Furthermore, in Example 3, when a lateral vibration is applied to the joint structure due to a large earthquake such as an earthquake, a force that separates the beam member 11 and the beam member 36 is applied. Can be reversibly displaced while compressing the coil spring 74. Therefore, also in the third embodiment, the same effects as in the second embodiment can be obtained, such as being able to absorb vibrations by elastic deformation of the coil spring 74 and effectively exhibiting a vibration control function that suppresses damage to the building. can get.
