  The joint metal fittings of these Patent Documents 1 and 2 can connect and fix the structural housing with joint strength different from that of the structure using no joint metal fitting. However, wooden buildings have a tendency to become larger, and there has been a demand for a joining structure of structural frames with higher strength. Various external forces such as a shearing load, a bending load, and a tensile load are applied to the connecting portion mainly with shaking. In particular, the present invention proposes a joint structure for a structural frame of a wooden building in which the strength against bending load and tensile load is improved as compared with the conventional structure.

In order to achieve the above object, as the means 1, in the joining structure of the structural housing of the wooden building in which the first structural housing and the second structural housing are connected and fixed via the joint metal fitting, A plurality of male screw members are embedded so as to be parallel to each other in the width direction of the structural housing, and a relative movement of the female screw member screwed with the male screw member along the axial direction of the male screw member The joint fitting is fastened and fixed to the first structural housing, and an insertion plate extending in the axial direction of the male screw member is formed in the joint fitting for each male screw member. A plurality of the plurality of insertion plates are inserted into the slits of the second structure housing, and a through hole formed in a side surface of the plurality of insertion plates in the inserted state and an insertion hole formed in the first structure housing The plurality of inserts It was to inserting the fixing pin to engage the plurality of insert plate against passage formed across rate.
With such a configuration, when a force that bends the second structural housing acts on the first structural housing or when a pulling force acts on the first structural housing, the male screw member Since these loads can be received by a plurality of insertion plates that extend in the axial direction and the fixing pins that are laid between the insertion plates, the resistance to bending and tensile loads at the joints is increased. As a result, the strength of the joint structure of the structural housing is increased.

Here, the `` structural frame '' is the part that corresponds to the framework when building a wooden building, such as foundation, wall, pillar, horizontal member (beam etc.), hut assembly, joist, bundle, foundation, rafter, main building Widely refers to diagonal materials such as girders and braces. “Movement along the axial direction of the male screw member relative to the female screw member to be screwed with the male screw member” means, for example, that a nut is screwed into a bolt member and the nut is relatively rotated around the outer periphery of the bolt. When moving along the bolt to approach the bolt head, or moving along the bolt by rotating the nut relative to the screw rod by screwing a pair of nuts on the outer periphery of the screw rod For example, the two nuts may be brought close to each other. The joining bracket is fastened to the first structural housing with a strong force by the proximity of the bolt head and the nut or the nuts. Further, the screw is a concept including a lag screw screw.
The insertion plate may be provided with a plurality of insertion plates in one joint fitting, or a single insertion plate may be provided for each of the plurality of joint fittings.

One of the points of the present invention is to fix a plurality of insertion plates arranged in the width direction of one second structural housing in the joint fitting with one fixing pin. When one insertion plate S is fixed with one fixing pin P as shown in FIG. 14A, the fixing pin P is inserted when the structural housing Q is shaken in the X direction with the joint portion as a base point. Since the plate S is supported only at one point, the insertion plate S cannot support the load at which the structural housing Q swings. That is, in synchronization with the swinging of the structural housing Q, the fixing pin P swings about the insertion plate S as a fulcrum as if it is a toy. On the other hand, in the present invention, as shown in FIG. 14B, since two or more insertion plates S (illustrated in the case of two sheets as one embodiment) are fixed in a bowl shape with one fixing pin P, A rigid-joint rigid frame structure is constructed for the vibration in the X direction, and the strength against the 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 fitting is fastened and fixed by the male screw member and the female screw member, but the pulling direction R of the male screw member is arranged in a straight line with the insertion plate S. As a result, the strength against the tensile force in the case where a pulling force in the Y direction with respect to the joint portion as a base point or a swing in a direction orthogonal to the XY plane is generated in the structural housing Q is increased.

Further, as the means 2, the joining metal fitting is configured individually for each of the insertion plates.
If the joining brackets are individually configured for each insertion plate as described above, the joining brackets can be arranged at intervals according to the width of the second structural housing to be inserted.
Further, as means 3, the joining metal fitting has a base portion, and the joining fitting is fixed to the first structural housing by the male screw member and the male screw member via the base portion. .
By providing the base portion in the joint metal, the joint metal can be easily attached to the first structural housing.
Further, as the means 4, the insertion plate is erected on the base portion. Thereby, it becomes easy to extend in alignment with the axial direction of a male screw member by fixing an insertion plate to a base part.
Further, as the means 5, the through hole of the plurality of insertion plates and the insertion hole of the first structural housing are collated in a state where the base portion is in contact with the second structural housing side. . This simplifies the collating operation between the through hole of the insertion plate and the insertion hole of the first structural housing.

Further, as means 6, a ring member is formed on the surface of the base portion that comes into contact with the first structural housing, and is embedded in a groove formed on the first structural housing side.
As described above, since the joint fitting is embedded so as to bite into the first structural body via the ring member, the strength against the shearing force of the joint portion between the first structural body and the second structural body is further increased. Become.
Here, the “ring member” has an insertion portion constituting an outer wall surrounded in a circular shape, but the planar shape of this insertion portion does not have to be circular, but is circular (including elliptical) Is better. Further, the insertion portion may be configured at the same height, or may be configured such that the insertion end side is sharpened or sawtooth-shaped for ease of biting into the wooden structure material side. The outer wall surrounded in a circular shape does not necessarily have to be continuous over the entire circumference, and a part thereof may be cut off.

Further, as the means 7, the first structural housing is a pillar.
That is, as the second structural frame, it is preferable to use a horizontal member such as a beam, a girder, a penetration, or a foundation. Since the pillar and the horizontal member connected to the column are members that should exhibit the most central strength when constructing a wooden building, the joint structure of the present invention is preferably applied to them.
As the means 8, the first structural casing is a cloth foundation or an independent foundation.
That is, it is preferable to use a pillar or a foundation as the second structural frame. This is because these are arranged below the wooden building, so that the strength higher than the upper is good for maintaining the strength of the whole wooden building.
Further, as the means 9, a plurality of the communication holes are formed, and the plurality of fixing pins are respectively inserted into the plurality of communication holes.
That is, there are a plurality of fixing pins inserted into a plurality of insertion plates. As a result, the yield strength against bending and pulling is further increased, and as a result, the strength of the joint structure of the structural frame is increased.

  ADVANTAGE OF THE INVENTION According to this invention, the joining structure of the structure housing | casing with high yield strength with respect to a bending load and a tensile load and high intensity | strength can be provided.

Hereinafter, the joining structure of the structural frame of the wooden building which is one embodiment of this invention is demonstrated based on drawing.
<Embodiment 1>
In the first embodiment, a column 1 is used as the first structural housing, and beams 2A and 2B are used as the second structural housing, and a joining structure of the structural housings connecting them is described. First, a basic configuration that forms a joint structure will be described in detail.
FIG. 1 is an exploded perspective view of a joint structure of a structural frame of a wooden building according to a first embodiment. As shown in FIG. 1, a total of nine circular grooves 3 of 3 × 3 are formed on the first contact surface 1 a to which the beam 2 </ b> A of the column 1 is connected so as to be arranged in an orderly manner in the vertical and horizontal directions. A first insertion hole 4 through which the column 1 is inserted back and forth is formed at the center position of the groove 3. As shown in FIG. 2, a total of four circular grooves 5 of 2 × 2 are arranged in the vertical and horizontal directions on the second contact surface 1b which is the back surface side of the first contact surface 1a to which the beam 2B is connected. It is formed to line up. The four grooves 5 of the second contact surface 1b are arranged at positions opposed to the four grooves 3 on the upper right when the first contact surface 1a is viewed from the front. That is, the first insertion hole 4 formed at the center of the groove 3 facing the first contact surface 1a opens at the center of each groove 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 slit 7 is formed over the back width (vertical length) of the beams 2A and 2B. Three slits 7 are formed at equal positions at three positions on the beam side abutting surface 2a on the beam 2A side at intervals equal to the interval between four rows of three first insertion holes arranged in the horizontal direction on the column 1 side. Has been. Two slits 7 are formed at two positions on the beam-side contact surface 2a on the beam 2B side at an interval equal to the interval between the four rows of the first first insertion holes arranged in the horizontal direction on the column 1 side. At the position of each slit 7 facing the beam-side contact surface 2a side, there is a relief portion 8 which is a flat shape for avoiding interference with a bolt head 20a or a nut 21, which will be described later, and is broadly cut into a shogi piece. 2A and 2B are formed in the vertical direction.
In the beam 2A, second insertion holes 9 intersecting with three (all) slits 7 are formed at four positions at equal intervals in the vertical direction at the back of the slit 7. Also in the beam 2B, second insertion holes 9 intersecting with two (all) slits 7 are formed at three positions at equal intervals in the vertical direction at the back of the slit 7.

As shown in FIGS. 1 and 3, the first embodiment uses an alloy first joint fitting 11 and a second joint fitting 12 as members for connecting the beams 2 </ b> A and 2 </ b> B to the column 1. The first joint fitting 11 used on the side of the beam 2A is a plane T-shaped by a base plate 13 having a vertically long rectangular appearance and a substantially rectangular insertion plate 14 extending forward at the center position in the left-right direction on the front surface of the base plate 13. It constitutes the basic skeleton. The vertical lengths of the base plate 13 and the insertion plate 14 are equal, and 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 gibels 15 are fixed to the back surface of the base plate 13 by welding in series in the vertical direction (vertical direction) at equal intervals. The interval between the three ring gibels 15 is equal to the interval between three rows of three grooves formed in the first contact surface 1a of the column 1 and arranged in the vertical direction. The ring jib 15 is a circular wall of the same height, which is configured to surround in a circular shape. The outer diameter of the ring gibel 15 matches the width of the base plate 13.
A through hole 16 is formed at the center position of the ring jib 15 to allow the base plate 13 to communicate with the front and back. The insertion plate 14 is formed with an arch-shaped cutout portion 18 that communicates in the left-right direction at a position facing each through hole 16 of the base plate 13. Near the front end of the insertion plate 14, pin holes 17 communicating in the left-right direction are formed at three locations along the vertical direction. A pin receiving portion 19 opened upward is formed above the pin hole 17.

The second joint fitting 12 used on the beam 2B side is a model in which the first joint fitting 11 is used for a tall beam in which three ring gibels 15 are formed. This is a model in which two ring gibels 15 used for a short beam are formed. Similar to the first joint fitting 11, the second joint fitting 12 constitutes a basic skeleton with a base plate 13 and an insertion plate 14 having a planar T shape. 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 2nd joining metal fitting 12, both the through-hole 16 and the notch part 18 formed in the insertion plate 14 are two. Near the front end of the insertion plate 14, pin holes 17 similar to those of the first joint fitting 11 communicating in the left-right direction are formed at two locations along the up-down direction. A pin receiving portion 19 similar to that of the first joint fitting 11 is formed above the pin hole 17.
In the first joining metal fitting 11 of the first embodiment, the base plate 13 has a length of 368 mm and a width of 77 mm, and the insertion plate 14 has a length of 368 mm and a width of 188 mm. Further, the base plate 13 and the insertion plate 14 of the second joint fitting 12 are configured to have the same width as the base plate 13 and the insertion plate 14 of the first joint fitting 11 and a length of only 278 mm. These sizes can be changed as appropriate. In the first embodiment, illustration of welding marks (beads) is omitted.
As shown in FIG. 1, nine bolts 20 and nine nuts 21 are used as fastening members in the present embodiment in order to connect and fix the first joint fitting 11 and the second joint fitting 12. The bolt 20 includes a bolt head 20a and a bolt body 20b having a male screw formed at the tip.
As shown in FIGS. 6A and 6B, the drift pin 23 as a fixing pin is a solid rod-shaped body made of an alloy, and the beams 2A and 2B are connected to the first and second joining fittings 11 and 12, respectively. Used for joining. The drift pin 23 has a tip 23a that is tapered and a bulging portion 23b that is crushed near the center rear portion and interferes with a hole inserted therethrough to prevent dropping. The length of the drift pin 23 corresponds to the width of the beams 2A and 2B. The longer one (FIG. 6A) is the same as the lateral width of the beam 2A, and the shorter one (FIG. 6B) is the beam 2B. It is the same as the width.

Next, an example of a specific construction method of the joining structure between the column 1 and the beams 2A and 2B using the first joining fitting 11 and the second joining fitting 12 will be described.
First, the first and second joining fittings 11 and 12 are joined to the column 1. As shown in FIG. 1, the three first joining fittings 11 are arranged in the horizontal direction, and the ring dowel 15 is inserted into the groove 3 of the first contact surface 1 a of the column 1. On the other hand, with respect to the second contact surface 1 b of the column 1, two second joining fittings 12 are arranged in the horizontal direction, and the ring gibel 15 is inserted into the groove 5. In this state, the back surface of the base plate 13 of the first joint fitting 11 is in close contact with the first contact surface 1a, and the back surface of the base plate 13 of the second joint fitting 12 is in close contact with the second contact surface 1b. Then, in this state, the bolt 20 is inserted into each first insertion hole 4 from the second contact surface 1b side of the column 1 shown in FIG. 1, and the nut 21 is screwed to the tip thereof.
At this time, at the position where the second joining metal 12 and the first joining metal 11 face each other, both the joining metal parts 11 and 12 are simultaneously fastened to the column 1 by the bolt 20 and the nut 21. At a position where only the first joining metal fitting 11 is present, the first joining metal fitting 11 is independently fastened to the column 1 by a bolt 20 and a nut 21.

As shown in FIG. 3, in a state where the first joint fitting 11 and the second joint fitting 12 are joined to the column 1, the beams 2A and 2B are respectively lowered from above, and the insertion plates 14 are joined to the beams 2A and 2B. Is inserted into the slit 7. At this time, as shown in FIG. 3, the drift pin 23 is driven (inserted) in advance into the uppermost second insertion hole 9 of the beams 2A and 2B. As a result, the drift pins 23 are placed on the pin receiving portions 19 of the joint fittings 11 and 12 as the beams 2A and 2B are lowered. Since the insertion holes 9 in the second and subsequent stages of the beams 2A and 2B are collated with the pin holes 17 of the respective joint fittings 11 and 12, the alignment is automatically completed. That is, a communication hole is formed in a direction orthogonal to the fiber direction of the beams 2A and 2B. Next, as shown in FIG. 4, the connection is completed by driving the drift pins 23 into the second insertion holes 9 in the second and subsequent stages of the beams 2A and 2B. In this state, as shown in FIGS. 5A and 5B, the drift pin 23 is arranged so as to intersect the insertion plate 14 of the first joint fitting 11 and the second joint fitting 12 in an orthogonal manner. Moreover, each insertion plate 14 will be extended corresponding to the axial direction of the volt | bolt 20, respectively.
In this way, the plurality of insertion plates 14 are inserted into one beam 2A, 2B, and the drift pin 23 is installed between the plurality of insertion plates 14, thereby joining the column 1 and the beams 2A, 2B. When a force that bends the beams 2A and 2B with respect to the column 1 or a pulling force of the beams 2A and 2B with respect to the column 1 acts on the portion, the plurality of insertion plates 14 are extended in line with the axial direction of the bolt 20. In addition, since the load can be received by the drift pin 23 installed between them, the yield strength against bending load and tensile load becomes very large, and as a result, the strength of the joint structure of this structural frame increases. It will be. Further, in the first embodiment, a structure of a plurality of insertion plates 14 that coincide with the axial direction of the bolt 20 and drift pins 23 that intersect perpendicularly to the beams 2A and 2B on both sides across the column 1 is formed. Thus, a rigid structure constituted by three straight metal fittings and the drift pin 23, which are the insertion plate 14 of the first joining fitting 11, the bolt 20 in a tension state, and the insertion plate 14 of the second joining fitting 12, is provided. It will be comprised and the intensity | strength of a junction structure will increase extremely.

First, a basic configuration that forms a joint structure will be described in detail.
As shown in FIGS. 7 and 8, the column base joint bracket 33 as a joint bracket is composed of an alloy box portion 34 and an insertion plate 35 as an alloy insertion plate erected on the box portion 34. ing.
The box portion 34 includes a rectangular shaped receiving plate 37 and a base plate 38 that are spaced apart from each other in the vertical direction, and four leg plates 39 that are disposed with a space between the receiving plate 37 and the base plate 38. Has been. The box part 34 has a leg plate 39 rigidly joined to the receiving plate 37 and the base plate 38 by welding, and has a substantially rectangular parallelepiped box-shaped outer shape as a whole. In the box portion 34, there are formed three small chambers 40 that are partitioned by a receiving plate 37, a base plate 38, and four leg plates 39 and communicate in the front-rear direction.
As shown in FIGS. 7 and 9, a circular through-hole 41 communicating in the vertical direction is formed at the center position of the base plate 38 of each small room 40. On the periphery of the through hole 41 on the upper surface of the base plate 38, a non-slip processing portion 43 made of a knurled mesh is formed. Around the anti-slip processing portion 43, four cylindrical positioning pins 44 are erected at predetermined intervals.
As shown in FIG. 9, the insertion plate 35 is a rectangular plate whose upper left and right corners are chamfered. The insertion plate 35 is formed to have the same length as the receiving plate 37 and is fixed to the center position in the width direction of the receiving plate 37 by welding. The insertion plate 35 extends in a direction parallel to the longitudinal direction of the receiving plate 37 and orthogonal to the upper surface of the receiving plate 37. Each insertion plate 35 is disposed above the three through holes 41 in the longitudinal direction. Pin holes 42 communicating in the front-rear direction are formed at 10 positions on the upper body side of the insertion plate 35. In the second embodiment, illustration of welding marks (beads) is omitted.

Next, an example of a specific construction method of the joining structure of the columns 32 using the column base joints 33 to the concrete foundation 31 will be described.
Two column-base fittings 33 are placed so as to cover the anchor bolts 45 protruding on the concrete foundation 31. Since the anchor bolts 45 are erected substantially in two rows and three rows, the two column base joints 33 are arranged adjacent to each other in the longitudinal direction of the box portion 34 as shown in FIG. The At this time, the anchor bolt 45 protrudes from the through hole 41 formed in the base plate 38 into each small chamber 40 of the box portion 34. The insertion plates 35 of both the column base joints 33 are each extended in a direction coinciding with the axial direction of the anchor bolt 45.
Next, as shown in FIG. 8, the washer 47 is placed on the base plate 38 so as to be arranged inside the four positioning pins 44, and the nut 46 is fastened to the anchor bolt 45 to connect the column base joint bracket. Installation on the foundation is completed.
The washer 47 used here is a disk-shaped plate body having a circular outer shape in which an oval-shaped through hole 48 is formed as shown in FIGS. 10 (a) and 10 (b). The through-hole 48 is arranged in an eccentric state so that the major axis direction is arranged from the center toward one direction of the outer periphery. As shown in FIG. 10A, a second anti-slip processing portion 49 that is engaged with the first anti-slip processing portion 43 is formed on the bottom surface of the washer 47. By using such a washer 47, for example, as shown in FIG. 9, even if the anchor bolt 45 is slightly deviated from the position of the core of the foundation, the washer 47 is rotated according to the protruding direction of the anchor bolt 45. Thus, the column base joint fitting can always be accurately positioned at the position on the foundation, and the column base joint bracket can be fastened and fixed together with the washer 47 by the nut 46 at the exact position.

Next, as shown in FIG. 11, the column 32 having two column connection slits 51 formed on the lower end surface of the column base joint 33 fixed to the concrete foundation 31 is formed in each of the column connection slits 51. It mounts on the receiving plate 37 so that the insertion plate 35 of the column base joining bracket 33 may be inserted. The column 32 is formed with an insertion hole 52 corresponding to the pin hole 42 on the receiving plate 37 side. By installing the column 32 on the receiving plate 37, the pin hole 42 is collated with the insertion hole 52, and a communication hole is formed in a direction orthogonal to the fiber direction of the column 32. A total of ten drift pins 55 are driven into the communication hole from the side to complete the connection between the insertion plate 35 and the column 32. The drift pin 55 has the same configuration as the drift pin 20.
In this way, by inserting a plurality of insertion plates 35 into one column 32 and constructing the drift pins 55 between the plurality of insertion plates 35, the joint portion between the concrete foundation 31 and the columns 32 is provided. When the force of bending the column 32 against the concrete foundation 31 or the pulling force of the column 32 against the concrete foundation 31 is applied, the two insertion plates 35 (a plurality of) are substantially aligned with the axial direction of the bolt 43. And the load can be received by the drift pin 55 installed between them, so that the resistance to bending load and tensile load becomes very large. As a result, the joint structure of this structural frame Strength will increase
