  That is, the main body 11 has an equiangular center line 11c extending equiangularly between the pair of flanges 12, 13 from a right angle 11b where the ends of the pair of flanges 12, 13 in the main body 11 are close to or in contact with each other. In contrast, it is formed in a line-symmetric pentagon. In the present invention, the shape of the main body portion 11 is arbitrary, and is not limited to a pentagon, but may be a triangle, a quadrangle, a hexagon or more, and a fan-shaped part having a curved shape. Of course, such a shape is also acceptable.

  The equiangular center line 11c is drawn by marking on the front surface and the back surface of the main body part 11, but the marking itself can be omitted. In addition, the pair of flange portions 12 and 13 are easily bent at right angles to the main body portion 11 at the right angle portion 11b of the main body portion 11 and the corner portions of the pair of flange portions 12 and 13 adjacent to the right angle portion 11b. At the same time, a small-diameter circular hole is formed to prevent distortion.

  The main body 11 is provided with slits 11d that are symmetrical with respect to the equiangular center line 11c and that cross the equiangular center line 11c. That is, the slit 11d is formed in a V-shape that is symmetric with respect to the equiangular center line 11c and is bent at a wide angle of 90 ° or more on the equiangular center line 11c so as to cross the equiangular center line 11c. It has a central refracting portion 11d1 on the equiangular center line 11c and both end portions 11d2 and 11d2 close to the pair of flange portions 12 and 13, respectively.

  Further, as shown in FIG. 2 and the like, a fixing member such as a nail, a screw, or a screw is passed through the main body 11 to fix the brace 4 (see FIG. 5) on the side of the right angle portion 11b with respect to the slit 11d. A plurality of (in this case, for example, five) through-holes (hereinafter referred to as right-angle portion side through-holes) 11e1 to 11e5 are formed, and the opposite side thereof, that is, the hypotenuse corner portion with respect to the slit 11d On the 11a, 11a side, a plurality of (here, six, for example) through-holes (hereinafter referred to as oblique side corner side through-holes) 11f1 to 11f6 through which similar fixing members are passed are formed. .

  Here, as shown in FIG. 2 and the like, the plurality of right-angled portion side through holes 11e1 to 11e5 and the plurality of oblique side corner side through holes 11f1 to 11f6 of the main body 11 are line-symmetric with respect to the equiangular center line 11c. Is provided. Therefore, in the odd-numbered right-angled portion side through holes 11e1 to 11e5, the central right-angled portion side through hole 11e3 is provided on the equiangular center line 11c. As will be described later, the right-angle-portion-side through-hole 11e3 is not used for fixing the brace 4 in this embodiment, but is used depending on the width of the brace 4 or the mounting angle or position of the brace 4. You may do it. Further, the right-angle portion side through-hole 11e3 and the central refracting portion 11d1 of the slit 11d can be used as a mark for marking the equiangular center line 11c.

  Moreover, in the main body part 11, both end parts 11d2 and 11d2 of the slit 11d are the flange parts of the plurality of right-angled part side through holes 11e1 to 11e5 and the oblique side corner part side through holes 11f1 to 11f6, respectively. 12 and 13 are formed so as to extend closer to the flange portions 12 and 13 than the right-angle portion side through holes 11e1 and 11e5 and the hypotenuse corner portion side through holes 11f1 and 11f6.

  Each of the flange portions 12 and 13 is formed by bending approximately 90 ° from the main body portion 11 and is fixed to the side surface of the horizontal member such as the column 2 and the base 3 or the beam 5. As shown in FIG. 4, the main body 11 is provided with the same shape and at an angle of 45 ° with respect to the equiangular center line 11c.

  As shown in FIGS. 3 (a) and 3 (b), the flange portions 12 and 13 are exposed on the lower surface of the horizontal member in the joint metal 7 for connecting the horizontal member such as the column 2 and the beam 5, respectively. Opening portions 12a and 13a that avoid the connecting plate 7b and the jaw receiving portions 7a2 and 7a2 (see FIG. 12) are provided.

  In addition, a plurality of fixing members such as nails, screws, screws, etc. are passed through the flange portions 12 and 13 for fixing to the side surfaces of the horizontal members such as the pillar 2, the base 3, or the beam 5 (here, for example, Through holes (hereinafter referred to as “flange portion side through holes”) 12b and 13b.

  Here, the flange part side through holes 12b, 13b provided in the flange parts 12, 13 are flattened so that the heads of fixing members such as screws and screws do not get in the way when the brace 4 is constructed, In order to improve the strength, the embossed holes projecting toward the pillar 2 or the base 3 are used, but the embossed holes themselves are arbitrary.

  Further, as shown in FIGS. 3A and 3B, the flange-side through holes 12b and 13b provided in the flange portions 12 and 13 are provided with horizontal members such as the pillar 2 and the base 3 along the grain. The positions are shifted from each other in the up-down direction or the left-right direction so that it is difficult to split.

  Further, as shown in FIGS. 3A and 3B, the corner portions of the flange portions 12 and 13 on the side far from the right-angled portion 11b are obliquely cut to provide oblique sides 12c and 13c, respectively.

<Mounting of brace 4 using brace fixing hardware 1 and its effect>
Next, the attachment of the brace 4 using the brace fixing hardware 1 configured as described above, the effects thereof, and the like will be described.

<When used at the junction between the pillar 2 and the base 3>
5 to 7 are a perspective view, a front view, and a plan view showing a state in which the brace 4 is attached to the joint portion between the pillar 2 and the base 3 via the brace fixing hardware 1 of the present embodiment, respectively.

  Here, when the brace fixing hardware 1 is attached to the pillar 2 or the base 3 and when the bracing 4 is attached to the brace fixing hardware 1, the same member, for example, the same screw or the like is used as the fixing member 6. Alternatively, other screws or nails may be used.

  At that time, in the brace fixing hardware 1 of the present embodiment, the main body part 11 of the brace fixing metal 1 is engraved with an equiangular center line 11c between the right angle part 11b and the pair of flange parts 12 and 13 at an equiangular angle. Therefore, when attaching the brace 4 to the brace fixing hardware 1, the fixing member 6 such as a screw is driven using the half-side through hole with the equiangular center line 11c as a mark.

  Specifically, in the case of the joint portion between the column 2 and the base 3 shown in FIGS. 5 to 7, for example, the upper side of the equiangular center line 11 c, that is, the side of the right angle portion on the pillar 2 side of the equiangular center line 11 c. The brace 4 is fixed by driving a fixing member 6 such as a screw into the holes 11e1 and 11e2 and the hypotenuse corner side through holes 11f1 to 11f3. However, depending on the angle, width, and position of the brace 4, for example, a position where the fixing member 6 such as a screw is driven into the right-angle portion side through holes 11e1 to 11e3 on the column 2 side and the hypotenuse corner portion side through holes 11f2, 11f3, etc. Can be changed. Similarly, in the case of the joint portion between the column 2 and the beam 5 shown in FIGS. 11e5 and the position where the fixing member 6 is driven into the hypotenuse corner portion side through holes 11f4, 11f5 and the like can be changed.

  On the other hand, in the case of the joint portion between the column 2 and the beam 5 shown in FIGS. 9 to 11 to be described later, for example, a lower side than the equiangular center line 11c, that is, a right angle portion on the column 2 side from the equiangular center line 11. The brace 4 is fixed by driving a fixing member 6 such as a screw into the side through holes 11e4 and 11e5 and the hypotenuse corner side through holes 11f4 to 11f6.

  Accordingly, as shown in FIGS. 5 to 7, after the brace 4 is attached to the joint between the pillar 2 and the base 3 via the brace fixing hardware 1 of this embodiment, a large shake is applied to the building due to an earthquake or the like. When the brace 4 is pulled greatly, the fixing member 6 such as a screw is pulled out by the pillar 2, the base 3, the brace 4, etc., or the right side portion side through holes 11 e 1 to 11 e 5 in which the fixing member 6 has been inserted. The slit 11d of the brace fixing hardware 1 spreads out before splitting from the brace 4 and the pillar 2 and the base 3 in the vicinity of the hypotenuse corner side through holes 11f1 to 11f6, the flange side through holes 12b and 13b. The padding hardware 1 is deformed.

  On the other hand, when the brace 4 is greatly compressed, a compressive force is transmitted to the pillar 2 or the base 3, and the fixing member 6 such as a screw is indented by the pillar 2, the base 3, the brace 4, or the like. Before splitting from the brace 4 and the pillar 2 and the base 3 in the vicinity of the right-angle part side through holes 11e1 to 11e5, the oblique side corner part through holes 11f1 to 11f6, the flange part side through holes 12b and 13b. The slit 11d of the brace fixing hardware 1 is narrowed, and the brace fixing hardware 1 is deformed.

  Therefore, according to the brace fixing hardware 1 of the present embodiment, when a large shake is applied to the building due to an earthquake or the like and the braiding 4 is pulled or compressed, the slit 11d is expanded or narrowed, thereby causing the brace fixing hardware. Since 1 is deformed first, it is possible to delay the splitting of the wood such as the pillar 2, the base 3, and the brace 4 and the removal of the fixing member 6, thereby reducing the damage to the entire building.

  Further, when fixing the brace fixing hardware 1 between the main body portion 11 and the brace 4, the right-angle portion side through-holes 11 e 1 to 11 e 5 close to the pillar 2 and the base 3 are formed by the slit 11 d provided in the main body portion 11. In addition, since it is defeated ahead of the oblique side corner portion through holes 11f1 to 11f6 far from the base 3, damage to the entire brace 4 can be reduced.

  In particular, in the brace fixing hardware 1 of this embodiment, as shown in FIG. 1 and FIG. 2 and the like, both end portions 11d2 and 11d2 of the slit 11d are respectively a plurality of right-angle portion side through holes 11e1 to 11e5 and oblique side corner portions. It is formed so as to extend closer to the flange portions 12 and 13 than any of the side through holes 11f1 to 11f6.

  Therefore, as shown in FIGS. 1 and 5, etc., the opening portions 12a and 13a provided in the flange portions 12 and 13 and the both end portions 11d2 and 11d2 of the slit 11d provided in the main body portion 11 are close to each other, When the brace 4 is greatly pulled or compressed by an earthquake or the like and the slit 11d is further greatly deformed, a portion between the openings 12a and 13a of the flange portions 12 and 13 and both end portions 11d2 and 11d2 of the slit 11d. The rims are greatly deformed, bent or twisted.

  Then, the main body portion 11 of the brace fixing hardware 1 is separated into the main body portion 11 on the right angle portion 11b side and the main body portion 11 on the oblique side corner portions 11a and 11a side through the slit 11d until the edge is cut. Independent movement and deformation.

  As a result, the opening portions 12a and 13a of the flange portions 12 and 13 and both end portions of the slit 11d provided in the main body portion 11 are compared with the case where the slit 11d is not provided and the case where only the slit 11d is provided. According to the brace fixing hardware 1 in which 11d2 and 11d2 are brought close to each other, the fixing joint 1 of the bracing fixing hardware 1, that is, the ultimate destruction of the entire building is delayed, and the bracing fixing hardware 1 against a large shake due to an earthquake or the like. Can increase the stickiness.

  FIGS. 8A and 8B are diagrams showing the proof stress confirmation test results for the brace fixing hardware 1 of the present embodiment in which the slit 11d is provided and the brace fixing hardware in which the slit 11d is omitted, respectively.

  8 (a) and 8 (b), the horizontal axis indicates the interlayer displacement δ (mm) of the in-plane test in which the brace fixing hardware to be tested is attached, while the vertical axis indicates the bracing fixing hardware to be tested. Shows the load P (kN) applied to the in-plane test specimen attached with, and measured the inter-layer displacement δ (mm) when the load P (kN) was applied to the in-plane test specimen attached with the brace fixing hardware did.

  As a result, the proof stress test result in the brace fixed metal fitting 1 of the present embodiment provided with the slit 11d shown in FIG. 8A and the proof stress test result in the brace fixed metal fixture omitted in the slit 11d shown in FIG. 8B. As is clear from comparison, in the brace fixing hardware 1 of the present embodiment provided with the slit 11d, the displacement δ which is the maximum load reaching point A is about 50 mm to 112 mm as shown in FIG. During this period, it can be seen that the brace fixed metal object 1 is displaced almost without the load P being lowered, and the displacement δ has dropped to about 112 mm and has decreased rapidly.

  On the other hand, in the case of the brace fixed metal fitting in which the slit 11d is omitted, as shown in FIG. 8B, the maximum load is reached up to about 75 mm after reaching the maximum load reaching point A when the displacement δ is about 70 mm. It can be seen that the load P is gradually decreased and thereafter the load P gradually decreases.

  Therefore, according to the brace fixing hardware 1 provided with the slit 11d according to the present embodiment, the load P is increased from the maximum load because the slit 11d expands after reaching the maximum load, compared with the case where the slit 11d is not provided. It was proved that it can be displaced greatly without falling.

  In other words, according to the brace fixing hardware 1 provided with the slit 11d of the present embodiment, the final joint of the bracing fixed hardware 1 is destroyed later than the case where the slit 11d is not provided, that is, the entire building is destroyed. It is possible to increase the stickiness of the brace fixed hardware 1 against a large shake caused by an earthquake or the like.

  Further, in the brace fixing hardware 1 of this embodiment, as is apparent from FIGS. 1, 2, 3, etc., a plurality of right-angle portion side through holes 11 e 1 to 11 e 5 and a plurality of oblique side corner portion side holes 11 f 1 to 11 f 6. Since the slit 11d is formed between the slits 11d, the split state can be easily confirmed from the slit 11d even when splitting occurs in the brace 4 at the attachment position overlapping the brace fixing hardware 1.

  For this reason, even if the brace 4 is damaged at the mounting position overlapping the brace fixing hardware 1, it can be quickly found and replaced through the slit 11d of the brace fixing hardware 1, and maintenance is also possible. improves.

  Further, as is clear from FIGS. 5 to 7, a plurality of (for example, five) fixing members 6 are used for fixing the main body 11 of the hardware 1 and the brace 4. However, the worker fixes the equiangular center line 11c stamped on the front and back surfaces of the main body 11 to the right-angle portion side through holes 11e1 and 11e2 on the pillar 2 side and the oblique side corner portion through holes 11f1 to 11f3. The member 6 is driven and fixed.

  Therefore, if it is decided in advance that the right-angled part side through holes 11e1 to 11e5 and the oblique side corner part through holes 11f1 to 11f6 on either one of the left and right sides with the equiangular center line 11c of the main body part 11 as a boundary will be used. It is possible to prevent a person from driving the fixing member 6 such as a screw into the right-angle portion side through holes 11e1 to 11e5 and the oblique side corner side through holes 11f1 to 11f6 on the side where the brace 4 does not exist by mistake. improves.

  Further, the brace fixing hardware 1 of the present embodiment is configured to be line-symmetric with respect to the equiangular center line 11 c of the main body 11. That is, the plurality of right-angled part side through holes 11e1 to 11e5 and the plurality of oblique side corner part side through holes 11f1 to 11f6 of the main body part 11 are provided symmetrically with respect to the equiangular center line 11c. The flange portions 12 and 13 have the same shape and are symmetrical with respect to the equiangular center line 11c, and the plurality of through holes 12b and 13b of the flange portions 12 and 13 also respectively correspond to the equiangular center line 11c. It is provided in line symmetry.

  Therefore, since the brace fixing hardware 1 of this embodiment does not have the left and right sides, not only the brace 4 is attached to the joint portion of the pillar 2 or the base 3, but also as shown in FIGS. Even when the brace 4 is attached to the joint between the column 2 and the beam 5, it can be used as it is without being conscious of the left and right sides.

  As a result, the brace fixing hardware 1 of this embodiment can be used not only for the joint between the pillar 2 and the base 3 but also for the joint between the pillar 2 and the beam 5, and can be used both internally and externally. Thus, the usability can be improved and the cost can be reduced.

<When used at the joint between column 2 and beam 5>
9 to 11 show a state before the brace 4 is attached to the joint between the column 2 and the beam 5 via the brace fixing hardware 1 of the present embodiment (the brace is shown by a two-dot chain line). Are a perspective view, a front view, and a plan view.

  In this case, the flange portion 13 is fixed to the side surface of the column 2, while the flange portion 12 is fixed to the side surface of the beam 5 that is a horizontal member.

  Here, a metal construction method is used for joining the pillar 2 and the beam 5 shown in FIGS. 9 to 11, and a joint hardware 7 as shown in FIG. 12 is used.

  As shown in FIG. 12, the metal joint 7 includes a pair of side plates 7a and 7a that are respectively inserted into two slits formed on the end face of the beam 5, and a connecting plate 7b that connects the side plates 7a and 7a. It is composed of The pair of side plates 7a and 7a are formed with a plurality of pin holes 7a1 (in this case, for example, four) into which drift pins (not shown) are inserted, and the pair of side plates 7a and 7a. In the lower part of 7a, jaw receiving portions 7a2 and 7a2 for receiving the lower surface of the beam 5 are provided.

  Therefore, when the pillar 2 and the beam 5 are joined using the joint metal 7 and the drift pin (not shown) or the like, the joint metal 7 is connected from the lower surface of the beam 5 as shown in FIGS. The plate 7b and the jaw receiving portions 7a2 and 7a2 are exposed.

  However, as shown in FIG. 1 and FIGS. 9 to 11, etc., the connecting plate 7 b of the joint hardware 7 exposed from the lower surface of the beam 5 is provided on the flange portions 12 and 13 of the brace fixing hardware 1 of the present embodiment. Since the openings 12a and 13a are formed so as to avoid the jaw receiving portions 7a2 and 7a2, even when the brace 4 is attached to the joint for joining the column 2 and the beam 5 using the joint metal 7, the connection is possible. Interference with the metal plate 7b and the metal joint 7 having the jaw receiving portions 7a2 and 7a2 can be prevented.

<How to cut out the brace fixing hardware 1 of the present embodiment from the coil 8>
FIG. 13 is a plan view showing a state when the brace fixing hardware 1 of the present embodiment in a flat plate state is cut out from the coil 8 which is a thin steel plate.

  As shown in FIG. 13, when the brace fixing hardware 1 of the present embodiment in a flat plate state before bending the pair of flange portions 12 and 13 with respect to the main body portion 11 is cut out from the coil 8 which is a narrow steel plate, The corner portions of the flange portions 12 and 13 on the side far from the right-angled portion 11b are cut obliquely, and the oblique sides 12c and 13c are provided so as to be parallel to both end faces of the coil 8.

  Therefore, when the brace fixing hardware 1 of this embodiment is cut out from the raw material coil 8, the oblique sides 12c and 13c of the flange portions 12 and 13 and both side surfaces 8a and 8a of the coil 8 are formed as shown in FIG. By matching, it is possible to reduce useless parts, so that the cost can be reduced. The provision of the oblique sides 12c and 13c is optional and is not an essential configuration of the present invention.

  In the description of the above embodiment, the slit 11d of the main body portion 11 is described as being formed in a V-shape bent at a wide angle of 90 ° or more on the equiangular center line 11c. However, the present invention is not limited to this. As long as the slit is symmetrical with respect to the equiangular center line 11c and crosses the equiangular center line 11c, the slit may be a straight slit or a curved shape, for example, instead of a curved shape. A (U-shaped) slit may be used. Further, instead of a single long hole-shaped slit, a slit formed by arranging a plurality of long holes in a dotted line in a V shape, a straight line, or a curved shape may be used, or the main body 11 may be pressed.
