Japanese Patent Laid-Open No. 2000-64426 JP, 2013-167133, A

  The joint metal fitting of these patent documents 1 and 2 can connect and fix a structural body with level difference joint strength compared with the structure which does not use a joint metal fitting. However, wooden buildings tend to be large in size, and there is a demand for joining structures with higher strength. A variety of external forces such as shear load, bending load, and tensile load act on the connecting portion mainly due to shaking. In particular, the present invention proposes a joint structure of a structural frame of a wooden building in which the strength against bending load and tensile load is improved as compared to the prior art.

In order to achieve the above object, in the joint structure of the structural frame of a wooden building, the first structural frame and the second structural frame are connected and fixed as a means 1 through a joint fitting. A plurality of male screw members are embedded parallel to one another in the width direction of the frame, and the relative movement of the male screw members along the axial direction of the female screw members engaged with the male screw members While fastening and fixing the joint metal fitting to the first structure frame, an insertion plate extending in the axial direction of the male screw member is formed in the joint metal member for each of the male screw members, insert the plurality of pre Ki挿 input plates within said second slit of the structural framework, which is formed in a plurality of prior Ki挿 entrance plate side surface formed hole and the second structural framework in the inserted state an insertion hole is collated, a plurality of pre Ki挿 entering play It was to inserting the fixing pin to engage a plurality of pre Ki挿 input plate against passage formed across.
With such a configuration, when a force to bend the second structural body acts on the first structural body or when a tensile force acts on the first structural body, the male screw member Since the loads can be received by the plurality of insertion plates extending in the axial direction and the fixing pins installed between the insertion plates, the resistance against bending load and tensile load of the joint portion is increased, and the result is As a result, the strength of the joint structure of the structural housing is enhanced.

Here, “structural framework” is a part corresponding to a framework when building a wooden building, and it is a foundation, a wall, a pillar, a horizontal member (beams etc.), a shed, a joist, a bundle, a bundle, a foundation, a rafter, a purlin , Girder, diagonal members like bracing etc. Also, "the relative movement of the female screw member in engagement with the male screw member along the axial direction of the male screw member" refers, for example, to screw the nut on the bolt member and relatively rotate the nut around the bolt outer periphery When moving the bolt along the bolt to make it approach the bolt head, or by screwing a pair of nuts around the outer periphery of the threaded rod and rotating the nut relative to the threaded rod, moving along the bolt There are cases in which the two nuts are made to approach each other. The approach of the bolt head and the nut or between the nuts tightens the joint metal fitting against the first structural frame with a strong force. Moreover, a screw is a concept also including a lag screw screw.
The insertion plate may be provided with a plurality of insertion plates in one joint fitting, and one insertion plate may be provided in each of the plurality of joint fittings.

One of the points of the present invention is to fix a plurality of insertion plates disposed in the width direction of one second structural frame in the joint metal fitting with one fixing pin. In the case where one insertion plate S is fixed by one fixing pin P as shown in FIG. 14 (a), the fixing pin P is inserted in the structure rod Q when a swing in the X direction occurs from the bonding point. Since the plate S is supported at only one point, the insertion plate S can not support the load at which the structural frame Q swings. That is, in synchronization with the swinging movement of the structural frame Q, the fixing pin P swings around the insertion plate S as if it were a toy. On the other hand, in the present invention, as shown in FIG. 14 (b), two or more (here, two in one embodiment, illustrated in the case of two) insertion plates S are fixed in a hook shape by one fixing pin P. For shaking in the X direction, a rigid frame structure is formed, and the strength against bending load in this direction is increased.
Further, one of the points of the present invention is that the plurality of insertion plates S are all extended in the axial direction of the male screw member. That is, the joint metal fitting is tightened and fixed by the male screw member and the female screw member, but the pulling direction R of the male screw member is disposed in line with the insertion plate S. As a result, the strength against the tensile force in the case where a tensile force in the Y direction starting from the joint portion of the structural body Q or a shake in the direction orthogonal to the XY plane occurs is increased.

As a means 2, the joint device is designed to have the insertion plate one.
Further, as the means 3, the joint metal fitting has a base portion, and the joint metal fitting is fixed to the first structural body via the base portion by the male screw member and the female screw member. .
By providing the base portion on the joint fitting, the joint fitting can be easily attached to the first structural frame.
Further, as the means 4, the insertion plate is set upright on the base portion. By this, by fixing the insertion plate to the base portion, it becomes easy to extend in the axial direction of the male screw member.
Further, as the means 5, the through holes of the plurality of insertion plates and the insertion holes of the second structural frame are collated in a state where the base portion is in contact with the second structural frame side. . As a result, the matching operation between the through hole of the insertion plate and the insertion hole of the first structural frame is simplified.

Further, as means 6, a ring member is formed on the surface of the base portion in contact with the first structural frame, and is embedded in a groove formed on the first structural frame side.
Thus, the joint metal fitting is embedded in such a way as to bite into the first structural frame through the ring member, so that the strength of the joint portion between the first structural frame and the second structural frame against shear force is high. Become.
Here, the “ring member” has an insertion portion that constitutes an outer wall that is circumferentially surrounded, but the planar shape of this insertion portion does not have to be circular, but it is circular (including elliptical) Is better. Further, the insertion portion may be configured to have the same height, or may be configured to be sharpened in the insertion end side or configured in a sawtooth shape in order to easily bite into the wood structural material side. The circumferentially enclosed outer wall does not necessarily have to be continuous all around, and a portion thereof may be cut.

Further, as the means 7, the first structural frame is a pillar.
That is, it is preferable to use a cross member such as a beam, a girder, a penetration or a base as the second structural frame. Since the pillars and the horizontal members connected thereto are members that must exert the most central strength when constructing a wooden building, it is preferable to apply the joint structure of the present invention thereto.
Also, as the means 8, the first structural frame is made to be a cloth foundation or an independent foundation.
That is, it is preferable to use a pillar or a base as the second structural frame. Because these are disposed below the wooden structure, it is better to maintain the strength of the entire wooden structure by making the strength higher than above.
Further, as the means 9, a plurality of the communication holes are formed, and a plurality of the fixing pins are respectively inserted into the plurality of the communication holes.
That is, there are a plurality of fixing pins inserted into a plurality of insertion plates. This further increases the above-mentioned resistance to bending and pulling, and as a result, increases the strength of the bonded structure of the structural frame.

  According to the present invention, it is possible to provide a joined structure of a structural frame having a large strength against bending load and tensile load and high strength.

That is, the first insertion holes 4 formed at the centers of the opposite grooves 3 of the first contact surface 1a are opened at the centers of the grooves 5 of the second contact surface 1b.
A plurality of slits 7 extending in the vertical direction of the beams 2A and 2B are formed in the beam side contact surface 2a connected to the column 1 of the beams 2A and 2B. The slits 7 are formed across the back width (vertical length) of the beams 2A and 2B. In the beam side contact surface 2a on the beam 2A side, three slits 7 are formed at equal intervals at three locations at intervals equal to the intervals of the four first insertion holes aligned in the lateral direction of the column 1 side. It is done. Two slits 7 are formed in the beam-side contact surface 2a on the beam 2B side at two places at intervals equal to the distance between the two rows of first through holes aligned in the lateral direction on the column 1 side. At a position facing each beam side contact surface 2a of each slit 7, a relief portion 8 which is cut in a broad pattern in the form of a shogi piece to avoid interference with a bolt head 20a or a nut 21 described later It is formed extending in the vertical direction of 2A and 2B.

The first joint metal fitting 11 used on the beam 2A side has a flat T-shape by the base plate 13 having an appearance of a vertically long rectangular shape and the substantially rectangular insertion plate 14 extended forward at the center position in the left-right direction of the front surface of the base plate 13 The basic framework of The vertical lengths of the base plate 13 and the insertion plate 14 are equal, and the width of the insertion plate 14 is about 2.5 times the width of the base plate 13. The insertion plate 14 is fixed to the base plate 13 by welding. Three ring dowels 15 are fixed to the back surface of the base plate 13 by welding at equal intervals in series in the vertical direction (longitudinal direction). The distance between the three ring bevels 15 is equal to the distance between the three rows of three grooves aligned in the longitudinal direction formed on the first abutment surface 1 a of the column 1 described above. The ring bevel 15 is a circular wall of the same height configured to surround. The outer diameter of the ring bevel 15 matches the width of the base plate 13.

The insertion plate 14 is formed with arched notches 18 communicating with the through holes 16 of the base plate 13 in the lateral direction. In the vicinity of the front end of the insertion plate 14, pin holes 17 communicating in the left-right direction are formed at three locations along the up-down direction. Above the pin hole 17, a pin receiving portion 19 opened upward is formed.

The second joint fitting 12 used on the side of the beam 2B is a model in which the first joint fitting 11 is a model used for a tall beam in which the three ring dowels 15 are formed, while the second joint fitting 12 is relatively more relatively It is a model in which two ring dowels 15 used for short beams are formed. The second joint metal fitting 12 constitutes a basic skeleton of the base plate 13 and the insertion plate 14 which are flat T-shaped like the first joint metal fitting 11. The second joint fitting 12 has the same ring dowel 15 as the first joint fitting 11, but unlike the first joint fitting 11, there are two ring dowels 15. Therefore, in the second joint fitting 12, both the through holes 16 and the two notches 18 formed in the insertion plate 14 are two.
