Description

The present invention relates to a metal joint suitable for use in joining shafts such as columns and beams in the construction of a wooden frame building, for example.

As a metal joint for joining the shafts to each other, for example, as disclosed in Patent Documents 1 to 4 below, there is a metal fitting using a cylindrical core metal fitting. In this core fitting, a female screw is formed at least at the end of the hole in the axial center portion, and a pin hole penetrating in the radial direction is formed in a part in the longitudinal direction.

In the metal joint of Patent Document 1, the core metal fitting (column base metal) is used together with the base metal that is inserted and attached to the anchor bolt of the foundation. That is, the base hardware is composed of a mounting body made of pipes and a plurality of joining plates having the same shape as each other protruding horizontally from the side surface of the mounting body, and the mounting body is inserted into an anchor bolt to form a foundation. Placed on top of. The end of the base is fixed to the joint plate, and the core metal fitting (column base hardware) is screwed to the upper end of the anchor bolt protruding from the mounting body. Then, this core metal fitting is embedded and fixed in the lower end of the pillar.

In other words, the core metal fittings (column base hardware) have the function of tightening and fixing the base hardware and the function of connecting the columns to the anchor bolts.

In the joint metal fitting of Patent Document 2, the core metal fitting (first joint rod) is used to fix the connecting metal fitting on the pillar (vertical member). That is, the lower portion of the core metal fitting (first joining rod) is inserted and fixed to the upper end portion of the pillar, and the connecting metal fitting is fixed to the upper portion protruding from the pillar. The connecting metal fitting has a quadrangular substrate larger than a pillar and an auxiliary plate arranged at intervals above and below, and a plurality of connecting pieces having the same shape are fixed to the outer peripheral portions of the substrate and the auxiliary plate, and these are fixed. The cross member is fixed to one piece.

In the metal joint of Patent Document 3, the core metal fitting (connecting metal fitting) is inserted into a joint hole penetrating in a direction orthogonal to the longitudinal direction at the end of a connected member (base, beam, etc.) which is a cross member. A screw hole is formed on the side surface of the core metal fitting (connecting metal fitting), and a plurality of receiving metal fittings that receive the end portion of the connected member to be joined are formed on the side surface of the end portion of the connected member by using the screw hole. It is attached. The plurality of brackets have the same shape as each other.

In addition, a through hole is formed in the axial center of the core metal fitting (connecting metal fitting), and the joining bolt provided in the connected member, which is a vertical member, is inserted, and a total of 6 vertical members and horizontal members are connected. A state in which the members are joined is obtained.

That is, this core metal fitting (connecting metal fitting) mainly has a function of holding the receiving metal fitting.

In the metal fittings of Patent Document 4, the core member (upper and lower screw pipes / upper and lower screw cylinders) is used together with the first-floor joint metal fittings and the second-floor joint metal fittings, and has a function of tightening the metal fittings and fixing them to anchor bolts and the like as in Patent Document 1. It has the function of connecting columns with anchor bolts and the like.

Further, FIGS. 6 and 7 of Patent Document 4 describe a configuration in which the second-order joint metal fitting is divided into a body portion and a wing portion, and a core member (upper and lower screw cylinder) is inserted into the body portion. Here, the core member (upper and lower screw cylinders) has a function of connecting the upper and lower bolts to each other and connecting to the second-order joint metal fittings.

This core member (upper and lower screw cylinder) is inserted into the body of the second-floor joint metal fitting, but since the second-floor joint metal fitting receives the end of the beam at the wing, the core member (upper and lower screw cylinder) and the body part It is not embedded in the material to be joined, but is assembled during the joining work.

Further, the body portion and the wing portion, and the body portion and the core member (upper and lower screw cylinders) are fixed with separate bolts at the time of joining. Therefore, the number of parts required for the joining work is large, and the workability is not good.

By the way, as in Patent Document 5 below, it has been proposed to construct a wooden framed building with a building panel as a building component having a shaft in advance. In a wooden frame building using such a building panel, the building panel is provided with a metal joint, and it is preferable that the metal joint does not protrude from the outer surface as much as possible. This is because the building panels can be stacked flat to improve the handleability.

Therefore, it is a main object of the present invention to make it possible to flatten the outer surface of the shaft when it is incorporated into a building panel, and to reduce the number of parts so that the joining work can be performed more simply.

The means for this is a rod-shaped fixed core member that is entirely embedded in one material to be joined, a tubular tube body that is inserted into the outer periphery of the fixed core member, and another joint that is integrated with the tube body. It is a joining metal fitting provided with a connecting member having an insertion fixing portion in which the entire tip side is inserted and fixed to the material.

In this configuration, the fixed core member is held entirely inside one material to be joined and accepts the insertion of a tubular portion of the connecting member that is fixed to the other material to be joined. If there is another material to be joined that has already been joined to one material, the fixed shaft member will be connected later while holding the tubular part of the connecting member fixed to the other material to be joined. Accepts the insertion of the tubular part of the connecting member to be fixed to the material to be joined. The connecting member holds the pipe body portion to be inserted into the fixed core member with respect to the fixed core member, and then fixes another material to be joined to the insertion fixing portion integrated with the pipe body portion. Alternatively, after fixing the insertion fixing portion to another material to be joined, the tubular portion is held by the fixing core member.

The outer surface of one material to be joined provided with a fixed core member and another material to be joined provided with a connecting member to be joined to one material is in a flat state without protrusion of the metal joint.

According to the present invention, the metal joint is a fixed core member that is entirely embedded in one material to be joined, and the pipe body portion and the pipe body portion that are inserted into the fixed core member, and the entire tip side is integrated with another jointed material. It is configured to include a connecting member having an insertion fixing portion that is inserted and fixed to the material. Therefore, it is possible to flatten the outer surface of one material to be joined having a fixed core member or a joint material between one material to be joined having a fixed core member and a connecting member and another material to be joined. As a result, it is possible to stack building components such as pillars and other shafts and building panels constructed by assembling the shafts in a flat manner, and the handling is good.

Further, since the connecting member is configured to be inserted and held in the fixed core member, the number of parts required for joining can be reduced, and the joining work can be simplified.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a joining example of joining building panels A and B having a shaft for constructing a wooden framed building. As shown in this figure, a part of the members constituting the metal joint 11 is embedded in one of the building panels A joined to each other, and the other building panel B is used in the one building panel A. On the other hand, it is joined via some other members constituting the joining metal fitting 11. The building panels A and B are joined together at the site.

The metal joint 11 that performs such a joint is a metal joint 11 that joins one or more other materials y to be joined to one material x. Therefore, in the case of the example shown in FIG. 1, one building panel A corresponds to one material to be joined x, and the other building panel B corresponds to another material y to be joined. At the same time, one axis a1 constituting one building panel A is attached to one material x, the other axis a2 is attached to another material y, and the other axis b1 constituting the other building panel B is the other. Corresponds to the material y to be joined.

As shown in FIG. 2, the metal joint 11 includes a fixed core member 13 and a connecting member 15.

Specifically, the fixed core member 13 is entirely embedded in one material to be joined x, and is formed in a rod shape. The overall shape of the fixed core member 13 is cylindrical, and the axial center portion has a through hole 31 penetrating in the longitudinal direction. At least the upper end of the through hole 31 is a female screw hole 32 extending in the longitudinal direction, and a female screw is formed on the inner peripheral surface.

Further, the fixed core member 13 has pin insertion holes 33, 34, 35 into which a pin 17 for fixing to one material to be joined x is inserted orthogonal to the longitudinal direction thereof. The pin insertion holes 33, 34, and 35 have the same circular shape as the cross-sectional shape of the pin 17, and the formation position and number thereof are set by the length of the fixed core member 13 and the number of connecting members 15 provided.

The connecting member 15 has a tubular tubular body portion 51 that is inserted into the outer periphery of the fixed core member 13, and an insertion that is integrated with the tubular body portion 51 and is fixed by inserting the entire tip side into another material to be joined y. It has a fixed portion 52. The tubular body portion 51 has a cylindrical shape that fits snugly to the outer peripheral surface of the fixed core member 13, and is formed shorter than the length of the fixed core member 13.

Further, the tubular body portion 51 has a rotation restricting portion 53 for preventing rotation with respect to the fixed core member 13. The rotation control unit 53 is composed of holes, notches, steps, irregularities, and the like. The rotation restricting portion 53 includes a position restricting locking portion 53a that directly prevents rotation with respect to the fixed core member 13, and a meshing portion 53b that acts indirectly.

The position-restricted locking portion 53a is formed at a portion corresponding to the pin insertion holes 33, 34, 35 when fitted to the fixed core member 13 in the tubular body portion 51, and the pin inserted into the pin insertion holes 33, 34, 35. It locks with 17. The meshing portion 53b meshes with the pipe body portion 51 in another connecting member 15 held side by side, and is composed of notches, steps, irregularities, and the like.

The insertion fixing portion 52 extends radially outward from the side surface of the tubular body portion 51 and has a flat plate shape. The shape of the insertion fixing portion 12 is a substantially strip shape narrower than the height of the beam material or the like which is the shaft, and has a tip side portion 54 to be inserted into the shaft and a base portion 55 for supporting the tip side portion 54.

The tip end side portion 54 is formed with a pin insertion hole 56 for holding a pin 18 (see FIG. 1) for fixing to the shaft. The base portion 55 is formed so that the positions of the cores S of the insertion and fixing portions 52 in all the connecting members 15 held by the same fixed core member 13 are at the same level in the inserted state with respect to the fixed core member 13. .. That is, the base portion 55 has a deformed portion that shifts the position of the tip end side portion 54 in the longitudinal direction of the fixed core member 13 as necessary (see FIG. 3).

The above-mentioned "core S of the insertion fixing portion 52" is a structure in which the insertion fixing portion 52 is substantially in the shape of a strip plate and has a pin insertion hole 56, and therefore is an intermediate position in the width direction of the portion having the pin insertion hole 56. Is. If the insertion fixing portion 52 is, for example, cylindrical, it is a position corresponding to the axis thereof. The above-mentioned pin insertion hole 56 formed in the insertion fixing portion 52 is formed in the core of the insertion fixing portion 52.

As shown in FIGS. 1 to 3, the above-mentioned "as needed" means that in the case of the connecting member 15a held at a position corresponding to the middle in the height direction of the shaft, the base 55 is viewed from the side surface. This is because it suffices to form the portion straight in the radial direction, and it is not necessary to shift the position of the tip end side portion 54.

The metal joint 11 has a closing member 19 in addition to the above-mentioned fixed core member 13 and one or more connecting members 15, and is provided with an adjusting cylinder member 16 as needed.

The closing member 19 is larger than the male screw portion 91 screwed into the female screw hole 32 of the fixed core member 13 and the male screw portion 91 that is integrated with the male screw portion 91 and is inserted into the fixed core member 13 to prevent the pipe body portion 51 from coming off. It has a holding portion 92 having a diameter. A bolt having a large-diameter head at one end of the male screw portion 91 is preferably used for the closing member 19.

The adjusting cylinder member 16 has the same configuration as the pipe body portion 51 of the connecting member 15. That is, the adjusting cylinder member 16 has a cylindrical shape that fits snugly to the outer peripheral surface of the fixed core member 13, and is formed shorter than the length of the fixed core member 13. Further, the adjusting cylinder member 16 has a rotation restricting portion 53 for preventing rotation of the fixed core member 13.

The joining hardware 11 exemplified in FIGS. 1 and 2 will be described in more detail below. The joining hardware 11 first joins the pillar material 101 and the beam material 102 as the shaft constituting one of the building panels A, and secondly connects the building panels A and B in a straight line. Therefore, two connecting members 15 are provided. On the other hand, the relationship between the column material 101 and the beam material 102 in the building panel A is such that the beam material 102 is joined to the side surface of the column material 101. Is another material to be joined. The other building panel B has a beam material 102 as a shaft, and this beam material 102 is another material to be joined y. Although not shown, face materials made of structural plywood or the like are attached to the building panels A and B.

As shown in FIG. 3, the fixed core member 13 buried and held in the column member 101 is set to a length that penetrates deeper than the height of the beam member 102 from the upper end surface of the column member 101, and holds the pin 17. Three pin insertion holes 33, 34, 35 are arranged at intervals in the longitudinal direction. The portion of the fixed core member 13 corresponding to the beam member 102 is the upper portion 13a, and the portion below it is the lower portion 13b. Further, the length of the fixed core member 13 is set so that the upper end surface of the upper portion 13a is located below the upper end surface of the pillar member 101. The difference in height between the upper end surface of the upper portion 13a and the upper end surface of the pillar member 101 is equal to or greater than the height of the holding portion 92 of the closing member 19.

The lowermost pin insertion hole 33 among the three pin insertion holes 33, 34, 35 is only for fixing to the pillar member 101, and is formed in the lower portion 13b. The other two pin insertion holes 34 and 35 are for fixing to the column member 101 and restricting the position of the connecting member 15. Of the two pin insertion holes 34, 35, the upper pin insertion hole 35 is formed at a position corresponding to the middle of the height of the beam member 102 in the upper portion 13a. The pin insertion hole 34 at the intermediate position is formed between the upper portion 13a and the lower portion 13b.

The two connecting members 15 are a middle-stage connecting member 15a and an upper-stage connecting member 15b. The metal joint 11 is provided with an adjusting cylinder member 16 in addition to these connecting members 15.

The middle connecting member 15a is for connecting the beam members 102 constituting one of the building panels A, and is an intermediate portion in the longitudinal direction in the upper portion 13a of the fixed core member 13, that is, an upper pin insertion hole. It is held at the position corresponding to 35. Therefore, the middle-stage connecting member 15a has a position-regulating locking portion 53a formed of a through hole 57 passing through the axis at the center of the tubular body portion 51. Further, at the upper end of the pipe body portion 51, there is a meshing portion 53b formed of a notch 58 that locks with the pipe body portion 51 of the upper stage connecting member 15b to prevent the upper stage connecting member 15b from rotating. The notch 58 has a shape in which a half in the radial direction at the upper end portion of the tubular body portion 51 is appropriately cut out at a height to provide a step. On the other hand, the lower end of the tubular body portion 51 is flat.

The insertion fixing portion 52 has an isosceles trapezoidal base portion 55 that becomes wider toward the outside, and a strip-shaped tip side portion 54 that extends from the tip of the base portion 55.

The upper connecting member 15b is for connecting the other building panel B and the beam member 102 constituting the panel B, and is the upper end portion in the longitudinal direction in the upper portion of the fixed core member 13, that is, the upper pin insertion. It is held above the position corresponding to the hole 35. At the lower end of the tubular body portion 51, a meshing portion 53b formed of a notch 58 that is locked and stopped around with the meshing portion 53b formed in the tubular body portion 51 of the middle stage connecting member 15a is formed.

The insertion fixing portion 52 has a substantially diamond-shaped base portion 55 in which the deformed portion formed on the tip end side is displaced downward, and a strip-shaped tip end side portion 54 extending from the tip of the base portion 55.

The adjusting cylinder member 16 is formed flat so that the upper end surface is in surface contact with the lower end surface of the tubular body portion 51 of the middle stage connecting member 15a, and the lower end portion is engaged with a pin 17 inserted into an intermediate pin insertion hole 34. It has a position-restricted locking portion 53a composed of a notch 59 for stopping. The shape of the notch 59 forms a convex portion 59a having a size shorter than the plan-viewing semi-arc that fits on the outside of one of the pins 17. The notch 59 may be formed in a semicircular arc shape in a side view, and the convex portions 59a may be formed on both sides.

The column member 101 and the beam member 102 fixed by the joint metal fitting 11 are subjected to the following processing. That is, at the upper end portion of the pillar member 101, a holding hole 103 having a circular shape in a plan view extending in the longitudinal direction from the upper end surface is formed at the center position of the upper end surface. The holding hole 103 has an upper holding hole 103a for holding the upper portion 13a of the fixed core member 13, and a lower holding hole 103b for holding the lower portion 13b of the fixed core member 13. The lower holding hole 103b has a thickness corresponding to the thickness of the fixed core member 13, whereas the upper holding hole 103a is thicker than that, and the tubular portion 51 of the connecting member 15 fits and corresponds. It is the thickness.

The pins 17 are inserted and held at the positions corresponding to the pin insertion holes 33, 34, 35 of the fixed core member 13 inserted into the holding holes 103 on the two side surfaces of the column member 101 in the direction orthogonal to the joining direction. An insertion hole 104 is formed. A slit between two side surfaces other than the side surface having the insertion hole 104 and the holding hole 103 corresponding to the beam member 102, through which the holding hole 103 and the side surface are communicated with each other and the base 55 of the insertion fixing portion 52 is passed through. 105 is formed.

A slit 106 for holding the insertion fixing portion 52 is formed at a portion of the beam member 102 in the longitudinal direction corresponding to the slit 105 of the column member 101, and corresponds to the pin insertion hole 56 of the insertion fixing portion 52. An insertion hole 107 for inserting and holding the pin 18 is formed in the portion.

In the joint metal fitting 11 having the above configuration, the pillar material 101 and the beam material 102 are joined to form the building panel A at a factory or the like as shown in FIGS. 4 and 5, and then the building panel A is formed. Is joined to another building panel B, which is separately configured as shown in FIG. 1, at the site.

In the configuration of the building panel A, first, as shown in FIG. 4, the fixed core member 13 is inserted into the holding hole 103 of the pillar member 101, and the two pins 17 are inserted into the lower and intermediate insertion holes 33 and 34. Hold at.

Next, the adjusting cylinder member 16 is inserted into the upper holding hole 103a of the pillar member 101, and the pipe body portion 51 of the middle stage connecting member 15a is inserted therein. The adjusting cylinder member 16 and the middle stage connecting member 15a are fitted into the fixed core member 13, the meshing portion 53b at the lower end of the adjusting cylinder member 16 is locked to the pin 17 already inserted, and the upper end thereof is the pipe of the middle stage connecting member 15a. It comes into surface contact with the lower end surface of the body portion 51. When the pin 17 is inserted into the upper insertion hole 35, the position of the middle connecting member 15a in the holding hole 103 is restricted and the rotation is stopped. At the same time, the adjusting cylinder member 16 is positioned and prevented from rotating.

After that, the beam member 102 is fixed to the insertion fixing portion 52 of the middle stage connecting member 15a with a pin 18. This fixing can also be performed prior to fitting to the fixed core member 13.

When joining the building panels A and B to each other, as shown in FIG. 1, one building panel A configured by embedding the fixed core member 13 is used for the other building by using the upper connecting member 15b. Join the panels B. That is, the pipe body portion 51 of the upper connecting member 15b is inserted and held in the fixed core member 13 of one of the building panels A. When the closing member 19 is screwed into the female screw hole 32 at the upper end of the fixed core member 13 after the pipe body portion 51 is inserted into the fixed core member 13, the upper connecting member 15b is prevented from coming off and the holding state is maintained. See FIG. 6).

Holding the upper connecting member 15b to the fixed core member 13 is easy because it is only necessary to screw the closing member 19, and it is highly convenient because bolts can be used for the closing member 19.

After that, the beam member 102 of the other building panel B is fixed to the insertion fixing portion 52 of the upper connecting member 15b protruding from the side surface of the pillar member 101. The beam member 102 can be fixed to the insertion fixing portion 52 of the upper connecting member 15b prior to the fitting of the tubular body portion 51 to the fixing core member 13.

In one of the building panels A to be joined in this way, as shown in FIG. 1, all the members to which the joining metal fitting 11 is held are housed in the shaft (pillar material 101, beam material 102), and the shaft has a shaft. There is no part protruding from the outer surface. Therefore, the building panels A can be stacked flat in post-manufacturing management and transportation, and the handling is good. The fact that the metal joint 11 does not protrude from the outer surface of the shaft is the same even after the building panels A and B are joined to each other, and there is no hindrance when assembling other members later, and the degree of freedom of construction is high. Is also expensive.

Further, since the connecting member 15 is configured to be inserted and held in the fixed core member 13, although the closing member 19 is required, it is not necessary to separately fix the connecting member 15 with a plurality of bolts, and the number of parts required for joining is increased. Man-hours can be reduced. Therefore, the joining work can be simplified and the construction time can be shortened.

Further, in the joined state of the materials to be joined x and y, the position of the connecting member 15 is restricted and detented by using a pin 17 that fixes the fixed core member 13 to one of the materials to be joined x. Moreover, even in the upper connecting member 15b that does not have the position restricting locking portion 53a, the upper connecting member 15b is locked to the middle connecting member 15a juxtaposed by the meshing portion 53b to prevent rotation. For this reason, the metal joint 11 made of a plurality of members can obtain a reliable joint state and also has high connection strength because the applied load is dispersed.

The connecting members 15 are juxtaposed along the longitudinal direction of the fixed core member 13, but since the insertion and fixing portions 52 have a configuration in which the core positions S are located at the same height as each other, the other material to be joined y. The insertion fixing portion 52 can be securely fixed to the joint without coming off the core of the material y to be joined.

Further, the joint metal fitting 11 provided with the fixed core member 13 and one or more connecting members 15 can be joined in a straight line as in the above-mentioned example by rearranging the connecting member 15 and by replacing the closing member 19. Joining in other forms is also possible.

An example thereof will be described below with reference to FIGS. 7 to 14. In this description, the same parts as those described above are designated by the same reference numerals and detailed description thereof will be omitted.

FIG. 7 shows an example in which two building panels A and B are joined in an L-shape in a plan view. That is, on the side surface of the pillar material 101 of the building panel A having the pillar material 101 as one joint material x and the beam material 102 as another joint material y in the direction orthogonal to the beam material 102, another cover material. A building panel B having a beam member 102 as a joining material y is joined. As shown in FIG. 8, the joining hardware 11 for performing such joining includes a fixed core member 13, two connecting members 15 (middle-stage connecting member 15a and upper-stage connecting member 15b) fitted therein, and an adjusting cylinder member 16. And a closing member 19.

The members other than the upper connecting member 15b of the joining metal fitting 11 have the same configuration as described above.

The upper connecting member 15b is different from the one in the above-mentioned example in the forming position of the insertion fixing portion 52 with respect to the pipe body portion 51. That is, since the joint is not an I-shape but an L-shape, the insertion fixing portion 52 is formed in the direction corresponding to the joint direction on the side surface of the tubular body portion 51. The shape of the insertion fixing portion 52 is the same as that of the above-mentioned example.

The metal joint 11 having such a structure is used in the same manner as described above to bond the materials x and y to be joined, and has the same function.

FIG. 9 shows an example of joining three building panels A, B, and C in a T-shape in a plan view. That is, a beam as another material to be joined y on one side surface of the pillar material 101 of the building panel A having the pillar material 101 as one material to be joined x and the beam material 102 as another material to be joined y. The building panel B having the lumber 102 is joined. Further, a building panel C having a beam member 102 as another material to be joined y is joined to another side surface adjacent to the side surface.

As shown in FIG. 10, the joining hardware 11 for performing such joining includes a fixed core member 13 and three connecting members 15 (middle-stage connecting member 15a, upper-stage connecting member 15b, and lower-stage connecting member 15c) fitted therein. And a closing member 19.

The fixed core member 13, the upper connecting member 15b, and the closing member 19 of the metal joint 11 have the same configuration as that of FIG. 2 described above.

The middle stage connecting member 15a is configured to be used for joining the building panel C, and the insertion fixing portion 52 is formed in the joining direction of the building panel C on the side surface of the pipe body portion 51. Since the position where the insertion fixing portion 52 is formed is the position where the position-restricted locking portion 53a made of the through hole 57 is formed, the rectangular window portion 61 is located at the position corresponding to the through hole 57 in the insertion fixing portion 52. Is formed. The window portion 61 is for allowing the pin 17 to be inserted.

The lower connecting member 15c is configured to be used for forming the building panel A, and is a side surface in the joining direction of the beam member 102 in the pipe body portion 51 having the same shape as the adjusting cylinder member 16 shown in FIG. The insertion fixing portion 52 is formed in the. The base portion 55 of the insertion fixing portion 52 has a substantially rhombus shape in which the deformed portion formed on the tip end side is displaced upward.

The metal joint 11 having such a structure is used in the same manner as described above to bond the materials x and y to be joined, and has the same function.

FIG. 11 shows an example of joining four building panels A, B, C, and D in a cross shape in a plan view. That is, on the side surface in the series direction of the pillar material 101 of the building panel A having the pillar material 101 as one joint material x and the beam material 102 as another joint material y, as another joint material y. The building panel B having the beam member 102 is joined. Further, a building having a building panel C having a beam material 102 as another material to be joined y on one side surface adjacent to the side surface thereof, and a building having a beam material 102 as another material to be joined y on the other side surface. Panel D is joined.

As shown in FIG. 12, the joining hardware 11 for performing such joining includes a fixed core member 13 and three connecting members 15 (middle-stage connecting member 15a, upper-stage connecting member 15b, and lower-stage connecting member 15c) fitted therein. And a closing member 19.

The members other than the upper connecting member 15b of the metal joint 11 have the same configuration as that of FIG. 10 described above.

The upper connecting member 15b includes an insertion fixing portion 52 for joining the building panel D in addition to the insertion fixing portion 52 for joining the building panel B. The shapes of the two insertion fixing portions 52 themselves are the same as each other.

The metal joint 11 having such a structure is used in the same manner as described above to bond the materials x and y to be joined, and has the same function.

FIG. 13 is a modified example of the closing member 19. That is, instead of the general bolt shape as described above as the closing member 19, a special bolt device 19a is used instead, and the upper end surface in the longitudinal direction of one material to be joined x is shown in FIG. As described above, an example of joining the pillar members 101, which are building components, is shown. By such joining, the second floor can be constructed on the first floor.

In the bolt device 19a, a fixing nut portion 97 that is integrated with the bolt body 95 and cannot rotate relative to the bolt body 95 is formed at one end side portion of the bolt body 95 in the shape of a shredded bolt in the longitudinal direction. Two nuts 96 and 98 are rotatably held in a portion of the bolt body 95 on the other end side of the fixing nut portion 97. Of these, the fixing nut 97 corresponds to the holding portion 92.

In such a bolt device 19a, a portion of the bolt body 95 opposite to the fixing nut 97 is held by a long nut 108 built in a lower end portion of the pillar 101, and the pillar 101 is used as a building panel A. After placing it on the pillar 101, the portion of the bolt body 95 on the fixing nut 97 side is screwed into the female screw hole 32 of the fixing core member 13. The screwing work can be performed through the recess 109 formed at the lower end of the column member 101. By screwing the bolt body 95, the fixing nut 97 hits the upper connecting member 15b, and the upper connecting member 15b is held. In this state, the two nuts 96 and 98 are rotated and tightened in order toward the fixed core member 13, and the nut 97 on the fixed core member 13 side is rotated in the reverse direction with the nut 98 on the nut 97 fixed. Let me.

In this way, by selecting the closing member 19, various joinings can be performed with the joining metal fitting 11.

The above configuration is one embodiment for carrying out the present invention, and the present invention is not limited to the above-mentioned configuration, and other configurations can be adopted.

For example, the fixed core member 13 may be inserted and held in a direction orthogonal to the longitudinal direction of the shaft.

Further, when a plurality of connecting members are provided, they may be arranged at other angles instead of being arranged so that the angles between them form a right angle as described above. In this case, if the material to be joined such as a pillar is not a square lumber with a quadrangular cross section but a round lumber with a circular cross section, for example, it is easy to connect at an appropriate angle.
