Description

  In a wooden house, the present invention relates to a construction hardware for connecting a horizontal member or a column and an end of a beam.

  In wooden frame construction houses, wooden framework construction houses, or 2 × 4 construction houses, there are many structural parts that join the ends of beams (horizontal materials) to horizontal members or columns, and hardware is used for earthquake countermeasures. Therefore, there is a demand for a structure that prevents falling out and falling off.

  In use, the beam receiver of Patent Document 1 is first fixed to the horizontal member of the wall (K) by a horizontal mounting plate (11) as a part thereof. The beam receiving plate 14 supports the lower surface of the end of the beam (H), and the left and right positions of the beam end are determined by the restricting plates 15 on both sides and the central reinforcing rib (17). This structure is fundamental as reinforcement hardware at the place where the ends of other horizontal materials (beams, joists, etc.) are butted against the horizontal material as seen in the joist metal fittings. A part of the beam bracket is exposed at the joint, which may interfere with the next process such as flooring and interior decoration.

  The joint hardware of Patent Document 2 is fixed to a horizontal member or a column by the contact plate portion 2, and the side plate portions 3 and 4 are inserted into slits (slits) provided on the end surface of the beam, and in the transverse direction from the side surface of the beam. Secure with bolts 18 to be inserted. In this case, the bonding hardware is hardly exposed, and there is no such disadvantage. However, since a deep slit is formed at the end of the beam, there is a risk that the end of the beam will break if the earthquake shakes greatly.

  The joint hardware of Patent Document 3 is that of Patent Documents 1 and 2 where the joint hardware is attached to either the horizontal member or the column side and the beam, whereas both the horizontal member or the column side and the beam side are attached. Bonding hardware is attached to each other and meshed with each other to achieve coupling. However, the part that engages with the joint hardware is a plate body protruding in the longitudinal direction of the beam, and it is necessary to form a deep slit in the end face of the beam.

  The beam receiving hardware is hardly exposed at the connecting part of the horizontal member or the column and the beam, and there is no need for deep slits or spot digging to fix the hardware. Offering is an issue.

It consists of the combination of the 1st metal fitting P fixed to the side of a horizontal member or a pillar, and the 2nd metal fitting S fixed to the end surface of a beam. The first hardware P and the second hardware S are basically polymerized by inserting the second hardware S into the first hardware P from the upper end, and are engaged with each other to form a horizontal member or a column side. The beam end is fixed to the horizontal member or column by combining the two hardwares on the beam side.
There are various structures to be overlapped and engaged, and the first hardware P and the second hardware S may be the same structure, one of which is inverted and engaged with the other to be polymerized. Basically, even if the structure is the same, the specific points may differ between the receiving side and the insertion side.

Each of the first hardware P and the second hardware S is a flat shape as a whole made of a plate material (steel plate or the like) having a substantially constant thickness, and both sides and upper ends of the molded plate material or A part for engagement and positioning is formed by folding or bending the lower end.
The first and second hardware P and S have a fixing hole through which a fixing member such as a countersunk screw passes, and a fixture for both hardware to attach them to the side surface of the horizontal member or the column or the end surface of the beam. A notch (which is often in the form of one end of the long hole cut out) is formed to accurately position the beam relative to each other, and thus to the horizontal member or column.

  As described above, when the first hardware P and the second hardware S are superposed and engaged with each other, the first hardware P and the second hardware S can be positioned with respect to each other, and the beam end face is tightly coupled to the horizontal member or the column. For this purpose, various specific configurations are employed. For example, at a place where the second hardware S is fitted and engaged in the gap formed by the first hardware P, the gap is made almost equal to the thickness of the second hardware S to eliminate backlash, The both side surfaces of the first hardware P thus formed are inclined surfaces that sag downward from above, and the second hardware S on the insertion side is automatically guided to the center of the first hardware P.

  In addition, since the attachment of the first hardware P and the second hardware S is based on the use of a countersunk screw, it is possible to adopt a structure that further reinforces the push-up displacement during an earthquake, taking into account the strength. is there.

The beam receiving hardware is flat and fits between the side surface of the horizontal member or column and the end surface of the beam, and the hardware is hardly exposed to the outside at the joint, so that there is no hindrance to the work of the next process. In addition, the construction hardware is inconspicuous even though it is still in the middle of construction.
In particular, in a building called a so-called “representation” where the frame is exposed indoors in a mountain hut style, hardware is not conspicuous and the indoor atmosphere is improved.

  By making the width wide, sufficient strength can be achieved, and if necessary, the hardware can be sealed inside the wood at the joint by digging a little. Encapsulation limits the contact between the hardware and the outside air, prevents condensation, and prevents corrosion of the wood and rusting of the hardware.

  The third surface portion is folded back in succession to the first surface portion, the second surface portion, and the first surface portion by bending a plate material having a substantially constant thickness along a bending line transverse to the longitudinal direction of the plate material. It is assumed that the hardware is composed. Two pieces of hardware having the same structure are prepared as a first piece of hardware P and a second piece of hardware S. These pieces of hardware P and S are arranged symmetrically in the longitudinal direction, and one of them is inverted and polymerized to the other to be engaged. Used by.

  The second surface portion of the first hardware P (the same applies to the second hardware S) is arranged upward by the thickness of the plate material at a position that does not overlap the first surface portion, and substantially parallel to the first surface portion, The third surface portion is connected by the first surface portion and the connecting surface portion, and is arranged in a position overlapping with the first surface portion and parallel to the upper portion of the plate material thickness by a factor of two. That is, the second surface portion is continuous to one end side of the first surface portion, and the second surface portion is continuous to the other end side of the first surface portion, but is folded back to the surface side of the first surface portion.

  In addition, the longitudinal dimensions of the first surface portion, the second surface portion, and the third surface portion are substantially equal. The first surface portion and the second surface portion are provided with fixing holes for attaching the hardware to the horizontal member or the column or beam, and the third surface portion and the first surface portion are holes for the engaging member A that penetrate these surface portions. And a hole for the engaging member B penetrating the second surface portion is provided in the second surface portion.

  Furthermore, it engages with the mating engagement member B at the edge of the third surface portion, and forms a longitudinal notch F at the position of the engagement member B or deeper than that, and also at the end of the second surface portion. The edge is engaged with the mating engagement member A, and a longitudinal notch E deeper than the position of the engagement member A is formed.

The first hardware P is fixed to the horizontal member or the column, and the second hardware S is fixed to the end face of the beam. The first hardware P is fixed with a countersunk screw with the second surface upward, the third surface downward, and the third surface front side. Further, the engaging member A is fixed to the horizontal member or the column by penetrating the holes provided in the third surface portion and the first surface portion, and the engaging member B is inserted into the horizontal member by penetrating the hole provided in the second surface portion. Or fix to the pillar.
Similarly, the second hardware S is fixed to the end surface of the beam, upside down from the first hardware P, and the third surface portion is the front side, using a countersunk screw and engaging members A and B.

The end face of the beam to which the second hardware S is fixed is brought close to the horizontal member or column to which the first hardware P is fixed, and the second hardware S is polymerized from above the first hardware P to the first hardware P. , Engage. Then, the second surface portion of the second hardware S enters and engages between the third surface portion and the first surface portion of the first hardware P, and the notch E provided at the edge of the second surface portion is the first hardware. The engagement member A on the P side is sandwiched. In addition, the second surface portion of the first hardware P enters and engages between the third surface portion and the first surface portion of the second hardware S, and a notch E formed at the edge of the second surface portion is the second hardware. The engagement member A on the S side is sandwiched.
In addition, from the 3rd surface part of the 1st metal fitting P, this 3rd surface part becomes the shape inserted in the clearance gap (space | interval d) of the 2nd hardware attached to a beam, and a beam end surface. The 3rd surface part of the 2nd hardware becomes the appearance inserted in the crevice (spacing d) between the 2nd surface part of the 2nd hardware, and a horizontal member side.

  Further, at the same time, the third surface portion of the second hardware S is fitted into and engaged with the gap (the interval is the thickness of the plate material) between the second surface portion of the first hardware P and the horizontal member or the column. The notch F at the edge of the third surface portion engages with the engagement member B on the first hardware P side, and the third surface portion of the first hardware P is the gap between the third surface portion of the second hardware S and the beam end surface. At the same time, the notch F at the edge of the third surface portion of the first hardware P is engaged with the engagement member B on the second hardware S side. As a result, the first hardware P and the second hardware S are positioned relative to each other in the left-right direction with respect to the longitudinal center line of the hardware.

  Since the distance between the second surface portion and the horizontal member or column, or the beam end surface is substantially equal to the thickness of the third surface portion, play occurs when the first hardware P and the second hardware S are overlapped and engaged as described above. Absent. Further, since the longitudinal lengths of the first surface portion, the second surface portion, and the third surface portion are substantially equal, when the first hardware P and the second hardware S are superposed and engaged, The lower end of the second surface portion of the two hardware S abuts on a connecting surface portion that is a folded portion between the first surface portion and the third surface portion of the first hardware P, and the vertical position is determined. Furthermore, the position of the second metal object S in the left-right direction relative to the first metal object P is determined by the engagement between the notch E and the engagement member A in the second surface part and the engagement between the notch F and the engagement member B in the third surface part. Determined.

Thus, the first hardware P and the second hardware S may be the same, and the structure of the hardware itself is simple. Moreover, since the second hardware S on the beam side is only inserted and engaged with the first hardware P fixed to the side surface of the horizontal material or the column from the upper side, the end of the beam with respect to the horizontal material or the column. The work of fixing the part is also easy.
Further, the first and second hardware P and S can be embedded in the connecting portion between the horizontal member or the column and the beam, and the beam receiving hardware is not exposed to the outside. Even in this case, since a deep slit or a spot digging is not necessary for mounting the hardware, the strength of the horizontal member, the column or the beam is not weakened.

1 to 7 relate to the first embodiment. The first hardware P and the second hardware S have exactly the same structure. When common to the first hardware P and the second hardware S, these are simply referred to as hardware.
As shown in FIG. 2, the first hardware P bends a plate material having a substantially constant thickness along bending lines x1 to x4 in the transverse direction XX with respect to the longitudinal direction YY of the plate material. Thus, the third surface portion c is configured in a manner of being folded back after the first surface portion a, the second surface portion b, and the first surface portion a. The first surface portion a and the third surface portion c are connected by the connecting surface portion 1.
The second hardware S is used in an arrangement or posture that is upside down with respect to the first hardware P and further inverted (FIG. 1).

The longitudinal dimensions of the first surface portion a, the second surface portion b, and the third surface portion c are substantially equal, the fixing holes 2 for attaching hardware to the first surface portion a and the second surface portion b are provided, and the third surface portion c. The first surface portion a is provided with holes 3 for engaging members A that penetrate these surface portions, and the second surface portion b is provided with holes 4 for engaging members B that penetrate the second surface portion b.

  Furthermore, it engages with the mating engagement member B at the edge of the third surface portion c to form a longitudinal notch F at the position of the engagement member B or deeper than that, and the other surface at the edge of the second surface portion. A notch E in the vertical direction is formed at a position deeper than the position of the engaging member A.

As shown in FIG. 3, the first hardware P fits into the pocket 6 formed on the side surface of the horizontal member 5 with the third surface portion being the front side and the third surface portion being the lower side in the vertical direction. And fix it with a countersunk screw 7. Reference numerals A and B are engaging members that use a countersunk screw and also serve to mount the first hardware P.
As shown in FIGS. 5 and 6, the second hardware S is fixed to the end face of the beam 8 with a countersunk screw 9 with the third surface portion being the front side and the third surface portion being upward in the vertical direction. Reference numerals A and B are engaging members, which use a countersunk screw and also serve to attach the second hardware.

The second hardware S attached to the end face of the beam 8 is superposed and engaged with the first hardware P (FIG. 7) fixed to the horizontal member 5 from above. That is, in the gap (interval d) between the second surface portion b formed on the back side of the upper half of the first hardware P and the bottom surface of the pocket (the side surface of the horizontal member or column), the second hardware S The three surface portions are inserted and engaged, and the engaging member B on the first hardware P side and the notch F on the edge of the third surface c of the second hardware S are engaged. At the same time, the second surface portion b of the second hardware S enters the first surface portion along the inner surface of the third surface portion of the first hardware P, and the notch E at the edge of the second surface portion b in the second hardware S is the first. Engage with the engagement member A on the metal P side. Further, the third surface portion of the first hardware P is fitted into the gap (interval d) between the second surface portion of the second hardware S and the beam end surface, and the notch F of the third surface portion of the first hardware P is the second hardware. Engage with the engagement member B on the S side.
In this way, the first hardware P and the second hardware S are so-called a saddle type combination in which the head and the tail mesh with each other.

It is supported by the surface portion 1 and is securely fixed. In this case, when the depths of the notches E and F are made to coincide with the positions of the mating engagement members A and B, the second hardware S is also supported by the engagement members A and B of the first hardware P and the beam 8 is supported. Is more stable.

  Furthermore, as shown in FIGS. 2 and 6, the second surface portion 2 is provided with a push-up portion 11 having a thickness of about the thickness of the plate material around the hole 3 through which the engaging member A passes in the first surface portion a. In the state where the surface portion b is inserted into the inner surface side of the third surface portion c, the play can be eliminated and a more stable engagement state can be obtained.

In FIG. 7, after the end of the beam 8 is coupled to the horizontal member 5, the second hardware is moved from the beam 8 side above the combined first hardware P and second hardware S to the horizontal material 5 side. The countersunk screw 10 which penetrates the 2nd surface part b of the 2nd metal fitting S from the connection surface part 1 of S and reaches the horizontal member 5 is driven. The countersunk screw 10 resists a force (reverse shear force) that lifts the end of the beam 8 upward during an earthquake.
The reverse shear force is generated when the brace acts to push up the end of the beam due to the shaking during the earthquake.

FIG. 8 shows a first hardware P according to a second embodiment obtained by modifying the first embodiment. In the first embodiment, the holes 3 for the engaging member A penetrating the third surface portion c and the first surface portion a are provided at two positions on the left and right sides, and correspondingly to the edge of the second surface portion b, two holes 2 are provided. It differs only in that the notch F is formed. The same parts as those in the first embodiment are denoted by the same reference numerals. The second hardware S has the same structure.
As in the case of the first embodiment, the first hardware P and the second hardware S are attached to the end surfaces of the horizontal member 5 and the beam 8, and when the beam 8 is fixed to the horizontal member 5, the first and second The hardware S is a combination of the saddles.
In addition, the code | symbol 12 is a through-hole formed in order to insert the said countersunk screw 10 (FIG. 7) which opposes pushing up.

FIG. 9 is a third embodiment, which is a modification of the second embodiment, and shows a second hardware S. FIG. It differs from Example 2 in the point of the notch E of a 2nd surface part edge. Others are the same as those in the first and second embodiments. The same parts are used for the same parts. The first hardware P has the same structure.
In the notch E in the third embodiment, one wall of the notch E is constituted by an ear-shaped portion 13 and can be deformed by pushing the screw 13a by an external operation.

  The screw 13a is screwed to the connecting surface portion 1 of the first hardware P, and after the first hardware P and the second hardware S are combined in the above-mentioned saddle shape, from the connecting surface portion 1 (below) of the first hardware P. Screw in. Then, as shown in FIG. 9C, the ear-shaped portion 13 of the second hardware S is deformed so as to block the notch E, and the second surface portion b of the second hardware is not changed even if a force pushing up to the beam side acts. It is possible to prevent the metal member P from coming out of the engagement member A.

10 and 11 show a fourth embodiment, in which FIG. 10 is a first hardware P and FIG. 11 is a second hardware S.
The first hardware P includes two coupling bolts 14 in the vertical direction across the first surface portion a and the second surface portion b of the first hardware P of the first embodiment, and the notches E and F, the fixing holes 2, It is fixed by welding avoiding the holes for the joint members A and B.

Other configurations, a structure including the first surface portion a, the second surface portion b, the third surface portion c, the engaging member A, the engaging member B, the notch E, the notch F, and the like are the same as those in the first embodiment.

The second hardware S is almost the same as the second hardware S of the first embodiment, and a through hole 15 through which the two coupling bolts 14 of the first hardware P are passed is formed in the connecting surface portion 1 (FIG. 11). B) The point is different.
The first hardware P is fixed to the horizontal member 5, the second hardware S is fixed to the end face of the beam 8, and the first hardware P and the second hardware S are combined in a bowl shape as in the case of the first embodiment. Then, the connecting bolt tip of the first hardware P protrudes from the through hole 15 of the connection surface 1 of the second hardware S, so that a nut is screwed into this portion, and the first hardware P and the second hardware S are connected. The bonding state is ensured against reverse shear force.
The connection between the bolt and the nut is strong, and the beam 8 does not come off the horizontal member 5 due to a large shake such as an earthquake.

12 and 13 show a fifth embodiment, in which FIG. 12 shows a first hardware P and FIG. 13 shows a second hardware S.
Each of the first hardware P and the second hardware S is obtained by folding up a plate material having a substantially constant thickness on both sides in the longitudinal direction in parallel to form left and right sleeve portions 16 and a main surface portion 17 therebetween. A structure in which one end in the vertical direction is a receiving surface portion 18 folded in the same direction as the sleeve portion 16 and a fixing hole 2 for hardware is provided in the main surface portion 17 is a basic structure.

  In addition to the basic structure described above, the first hardware P (FIG. 12) has an inner piece 19 in which the sleeve portion 16 is folded from the main surface portion 17 to the surface side and the tip is folded back inside. 19 is formed on an inclined surface 20 in which the inner piece 19 is wide in the vertical direction from the upper side to the lower side. On the other hand, two coupling bolts 14 are welded and fixed to the main surface portion 17 in the vertical direction while avoiding the fixing holes 2. The coupling bolt 14 has a tip projecting from the upper end of the main surface portion 17, and a screw is engraved at that portion. Reference numeral 21 denotes a support portion, which is formed by bending the upper end of the main surface portion 17 into a U-shape. The tip of the coupling bolt 14 passes through this portion.

That is, the first hardware P is fixed to the horizontal member 5 with the front end of the bolt facing upward and the sleeve portion 16 protruding to the front side, and the second hardware S is fixed to the end surface of the beam 8 with the receiving surface portion 18 facing upward. The sleeve 16 is fixed so that the sleeve 16 protrudes to the front side, the sleeve 16 of the second hardware S is positioned inside the sleeve 16 of the first hardware P, and the inner piece 19 The inclined surface 20 of the outer piece 22 is applied to the inclined surface 20 and dropped and polymerized.

  Then, with respect to the first hardware P, the second hardware S is drawn toward the horizontal member 5 by the guide of the inclined surfaces 20 and 23, and the front end of the coupling bolt 14 is the through hole 15 of the second hardware S. Protrude from. A nut is screwed onto the tip of the coupling bolt 14 to firmly bond the first hardware P and the second hardware S.

In the fifth embodiment, since the second hardware S is attracted to the first hardware P by the contact and guidance of the inclined surfaces 20 and 23, the butt coupling of the beam 8 to the horizontal member 5 is tight. Done. The abutment of the inclined surfaces 20 and 23 also serves as an engagement that prevents the movement in the front-rear direction, that is, the direction in which the first hardware P and the second hardware S are pulled apart.
In addition, the space | interval of each sleeve part 16 in the 1st metal fitting P and the 2nd metal fitting S, each height, the vertical direction dimension of the main surface part 17, etc. are each dimension which can be engaged with the said superposition | polymerization. .

  14 and 15 show a sixth embodiment, in which FIG. 14 is a first hardware P and FIG. 15 is a second hardware S. In this embodiment, a structure having a main surface portion 17 and sleeve portions 16 on both right and left sides thereof is fundamental. A fixing hole 2 is formed in the main surface portion 17.

  In the basic structure of the first hardware P, the sleeve portion 16 is folded from the main surface portion 17 to the surface side, and the tip thereof is folded back inward so as to be U-shaped in cross section, the lateral surface portion 25 and the inner surface portion 26. The horizontal surface portion 25 is an inclined surface 27 close to the main surface portion 17 from the upper side to the lower side in the vertical direction. The lower end portion of the main surface portion 17 is configured as a receiving surface portion 18 that is folded in the same direction as the sleeve portion 16.

  Further, the coupling bolt 14 is fixed to the main surface portion 17 in the vertical direction so as to avoid the fixing hole 2, and the tip is protruded from the horizontal surface portion 21a provided at the upper end of the main surface portion 17, and a screw is attached to that portion. Is engraved. Further, a concave portion 28 having an open upper end is formed on the upper end portion of the main surface portion 17 to receive a tongue piece 33 (second metal fitting S, which will be described later) of the thickness of the plate material from the back side of the plate material.

  In the basic structure of the second hardware S, the sleeve portion 16 is folded from the main surface portion 17 to the front surface side, and the tip is folded outward so as to have a U-shaped cross section, the lateral surface portion 30, and the outer piece 31. The edge surface of the outer piece 31 is an inclined surface 32 in a direction away from the main surface portion 17 from above to below in the vertical direction. Further, the upper end portion of the main surface portion 17 is a support portion 21 having an L-shaped cross section that is a horizontal surface portion 21 b that is folded up and then bent downward, and a tongue piece 33. A through hole 15 for the coupling bolt 14 is formed in the horizontal surface portion 21 b of the support portion 21.

  The first hardware P is attached to the side surface of the horizontal member 5 so that the tip of the coupling bolt 14 is upward, the receiving surface portion 18 is downward, and the sleeve portion 16 protrudes to the front side, and the second hardware S is The support portion 21 is attached to the end face of the beam 8 so that the sleeve portion 16 protrudes to the front side. Next, the end face of the beam 8 is brought close to the horizontal member 5 and, similarly to the case of the fifth embodiment, the upper and lower sides of the first hardware P and the second hardware S are aligned and overlapped from the vertical direction in an inverted arrangement.

Then, the sleeve 16 of the second hardware S is positioned inside the sleeve 16 of the first hardware P, and the inclined surface of the outer piece 31 of the second hardware S is formed on the inclined surface 27 of the lateral surface 25 of the first hardware P. 32 is in contact with and overlaps, and the tongue 33 of the first hardware P is fitted into the recessed portion 28 of the second hardware S from above. Further, the coupling bolt 14 of the first hardware P is inserted into the through hole 15 provided in the horizontal surface portion 21b of the support portion 21 of the second hardware S, and the lower end edge of the main surface portion 17 of the second hardware S is the first hardware P. It contacts the receiving surface portion 18. Finally, a nut is screwed onto the tip of the coupling bolt 14 projecting from the horizontal plane portion 21 of the second hardware S to firmly bond the first hardware P and the second hardware S.
In addition, the space | interval of each sleeve part 16 in the 1st metal fitting P and the 2nd metal fitting S, each height, the vertical direction dimension of the main surface part 17, etc. are each dimension which can be engaged with the said superposition | polymerization. .

  This structure has an advantage that it is easy to process and easy to manufacture because the bending angle of the plate material when forming the sleeve portion 16 stops at most 90 °. Further, since the tongue piece 33 of the second hardware S is fitted in the recessed portion 28 at the upper end portion of the first hardware P, it is easy to position, and the force in the front-rear direction that tries to separate the beam 8 from the horizontal member 5 is reduced. It is possible to reduce the load of the coupling bolt 14 that opposes.

  FIGS. 16 and 17 show Example 7, which is the same as Example 6. However, in the basic structure, the left and right sleeve portions 16 are arranged along a symmetrical inclined line with respect to the center line in the vertical direction. The interval between the sleeve portions 16 is reduced from the upper side to the lower side. Therefore, the sleeve portion 16 has a so-called double taper structure in which the inclination in the front and back direction of the horizontal surface portion 25 and the inclination in the left-right direction of the vertical surface portion 24 (inclined surface 34) overlap.

  In order to facilitate the manufacture, the sleeve portion 16 of the first hardware P has an L-shaped cross section including the vertical surface portion 24 and the lateral surface portion 25, and the sleeve portion 16 of the second hardware S has the outer piece 31 standing upright. The structure is in close contact with the surface portion 24. The left and right vertical surfaces 24 are also arranged so that the distance between the left and right vertical portions 24 is reduced from the upper side to the lower side together with the outer piece 31. Other structures are almost the same as those in the sixth embodiment. The same reference numerals are used for the same parts of the first hardware P and the second hardware S, and detailed description thereof is omitted.

  The first hardware P is attached to the side surface of the horizontal member 5 with the tip end of the coupling bolt 14 facing upward, and the second hardware S is attached to the end surface of the beam 8 with the support portion 21 facing upward. Next, the end of the beam 8 is brought close to the horizontal member 5, and the second hardware S is inserted into the first hardware P from above to be polymerized and engaged. The front end of the coupling bolt 14 protrudes from the through hole 15 of the support portion 21, and the horizontal plane portions 21 a and 21 b of the first hardware P and the second hardware S are superposed. A nut is screwed into the protruding portion of the coupling bolt 14 to firmly bond the first hardware P and the second hardware S.

The mode of superposition and engagement is the same as in the case of Example 6, but the beam 8 is drawn in the front and back direction with respect to the horizontal member 5 by contact and guidance of the inclined surface 27 and the inclined surface 32 of the hardware. In addition, the second hardware S is positioned along the center line of the first hardware P in the left-right direction by the contact and guidance between the left and right inclined surfaces 34 of the first hardware P and the sleeve 16 of the second hardware S. The second hardware S is attracted to the first hardware P.
