The first connecting member 21, which is a stamped and bent piece of metal plate, is provided with two connecting portions 26 separated in the axial direction N of the central axis 24 so as to face each other. Since the bridging portion 27 is bridging between the ends in the thickness direction of the entire first connecting member 21 on the side perpendicular to the axial direction N of 24, the two connecting portions 26 are located at the center. They are connected by a bridging portion 27 having a width dimension in the axial direction N of the shaft 24 . In addition, each connecting portion 26 has a length dimension in a direction perpendicular to the axial direction N of the central axis 24 and also perpendicular to the thickness direction of the entire first connecting member 21. This length dimension is the length Both ends 26A and 26B in the direction are dimensioned so as to reach the door frame 2 and the auxiliary member 8 forming the frame of the wall 4. As shown in FIG.

7(A) and 7(C), the end 26A on the auxiliary member 8 side of both ends 26A and 26B in the length direction of each connecting portion 26 has a central axis 24. A twist angle of 90°-α is provided, which is an angle of inclination to the outside of the first connecting member 21 with respect to a direction perpendicular to the axial direction N of the two connecting portions. 26 are twisted in directions opposite to each other, and the end 26B on the side of the door frame 2 is provided with such a twist angle as shown in FIGS. Not done. An intermediate portion 26C is provided between the end portion 26A on the side of the auxiliary member 8 and the end portion 26B on the side of the door frame 2 to gradually eliminate the torsion angle of 90°-α . The end portion 26B on the side of the door frame 2 is provided with a large-diameter first hole 28 as an insertion portion for inserting the central shaft 24, and the end portion 26A on the side of the auxiliary member 8 is provided with a hole shown in FIG.

A third hole 30 is also provided for inserting tools 50,51.

Further, the bridging portion 27 is provided with an elongated hole 31, which is elongated in the longitudinal direction of the connecting portion 26. It becomes the formed strength reduction part.

As described above, the first connecting member 21 has a substantially U-shaped overall shape formed by the two connecting portions 26 and the bridging portion 27 bridging the connecting portions 26 . However, the shapes of the ends 26A of the two connecting portions 26 on the side of the auxiliary member 8 are open to the outside of the first connecting member 21 due to the torsion angle 90°-α described above. In other words, the center shaft 24 has a V-shape opening outward in the axial direction N of the center shaft 24 .

In FIG. 8, in order to connect the ends 26A of the connecting portions 26 on the side of the auxiliary member 8 to the auxiliary members 8 by the couplings 25 of FIG. It shows the case where loads W acting in opposite directions in the axial direction N are applied. When such a load W acts on the ends 26A on the auxiliary member 8 side, the torsion angle 90°-α of the ends 26A on the auxiliary member 8 side shown in FIG. Due to the influence of the load W, the bridging portion 27 bends in the direction of the thickness of the bridging portion 27 (thickness direction of the entire first connecting member 21) in the direction of protruding outward from the first connecting member 21. In addition, due to the influence of the load W, the center shaft 24 is deformed at each end 26B on the side of the door frame 2 connected to the end 26A on the side of the auxiliary member 8 via the intermediate portion 26C. A torsion angle 90°-β is generated as an inward inclination angle of the first connecting member 21 with respect to the direction orthogonal to the axial direction N, and this torsion angle 90°-β The portions 26B are twisted in opposite directions.

As a result, in the entirety of the first connecting member 21, the shape of the end portion 26B on the side of the door frame 2 in each of the two connecting portions 26 has a twist angle of 90°-β . It becomes an inverted V shape that is closed.

Since the bridging portion 27 is provided with the elongated hole 31 serving as a strength-reduced portion for reducing the strength of the bridging portion 27, the bridging portion 27 is greatly affected by the load W, as described above. Therefore, the twist angle 90°-α of the end portion 26A on the auxiliary member 8 side is reduced or eliminated, and the twist angle 90°- at the end portion 26B on the door frame 2 side. The generation of β is also made more reliable.

Of these end portions 35A and 35B, the end portion 35B on the side of the door frame 2 is provided with a large-diameter first hole 37 as an insertion portion for inserting the central shaft 24. , a small-diameter second hole 38 is provided at the end portion 35A on the side of the auxiliary member 8 as an insertion portion for inserting the coupler 34 shown in FIG. 19 and 20, each connecting portion 35 is also provided with a third hole 39 for inserting couplers 50 and 51, which are tapping screws.

Further, of the lengthwise end portions of the connecting portion 35 of the bridging portion 36, the end portion 36B on the door frame 2 side protrudes toward the central shaft 24 side, in other words, toward the first connecting member 21 side. A projecting piece 40 is formed. An end portion 36B of the bridging portion 36 is provided with a notch portion 41 at a location near the projecting piece portion 40. In the present embodiment, the notch portion 41 is formed on both sides of the projecting piece portion 40 at the end portion 36B. 2 are provided in the In addition, as shown in FIG. 9B, the protruding piece 40 of the present embodiment is formed so as to be slightly bent inward in the thickness direction of the second connecting member 22 from the bridging portion 36. .

The projecting piece 40 formed on the second connecting member 22 in this manner is bent in the thickness direction when a load acts on the projecting piece 40 in the thickness direction of the second connecting member 22 as a whole. Two notches 41 are provided at the ends 36B of the bridging portion 36 on both sides of the protruding piece 40, and these notches 41 are formed on the bridging portion. Since the base end portion of the projecting piece 40 at 27 is formed as a reduced strength portion for reducing the strength, the projecting piece 40 can be easily bent even if the load is small.

The second connecting members 22 are aligned in a direction orthogonal to the axial direction N of the central shaft 24 and are parallel or substantially parallel.

Therefore, the projecting piece 40 constitutes a parallel means 45 for aligning the first connecting member 21 and the second connecting member 22 in a direction perpendicular to the axial direction N of the central shaft 24 and making them parallel or substantially parallel. It is supposed to Also, when the first connector 20A is inserted into the gap between the door frame 2 shown in FIG. Due to the parallel function of the means 45, the first connecting member 21 and the second connecting member 22 are arranged in the direction of the gap between the door frame 2 and the auxiliary member 8, which are two building materials, and the door frame 2 and the auxiliary member. 8, the direction perpendicular to the thickness direction of the door frame 2 (also the thickness direction of the wall 4 shown in FIGS. 1 and 2) The first connector 20A can be arranged in the vertical direction, and the first connector 20A arranged on the upper frame member 2C of the door frame 2 can be arranged in the horizontal direction, while being parallel or substantially parallel.

It is attached to the door frame 2 by being combined. The second connector 20B shown in FIG. 3 is composed of the first connector 21, the bearing member 23, and the central shaft 24. Therefore, the second connector 20B extends from the first connector 20A to the second connector. It has the same structure as the one with 22 removed. Such a second connector 20B is also attached to the door frame 2 at the factory by joining the bearing members 23 to the left and right side frame members 2A and 2B of the door frame 2 by welding or the like.

The door frame 2 with the first connector 20A and the second connector 20B factory-installed is transported to the work site where the hinged door device of FIG. Before the shown panel 6 is attached to the core member 5, the left and right side frame members 2A, 2B of the door frame 2 and the core members 5A, 5B of FIG. 3 to form the wall 4 of FIG. The first connector 20A and the second connector 20B are inserted into the space in the left-right direction between the auxiliary member 8 attached to the reinforcing member 7 and the upper frame member 2C of the door frame 2 and the upper frame member 2C of the door frame 2, as shown in FIG.

In this embodiment, when performing the work of arranging the door frame 2 and the first and second connectors 20A and 20B inside the opening 4A of the wall 4 as described above, the first connection of the first connector 20A is performed. Even if the member 21 and the second connecting member 22 are rotatable about the central shaft 24, they are attached to the side frame members 2A and 2B of the door frame 2 and the reinforcing member 7 coupled to the core members 5A and 5B. With respect to the first connecting member 20A inserted into the space in the left-right direction between the supporting member 8 and the supporting member 8, the first connecting member 21 and the second connecting member 22 are connected by the parallel function of the parallel means 45 described above. They can be aligned in the horizontal direction, which is the interval between the side frame members 2A, 2B and the reinforcing member 7, and the vertical direction, which is the direction orthogonal to the thickness direction of the door frame 2, and can be made parallel or substantially parallel. Also, regarding the first connector 20A inserted into the vertical gap between the upper frame member 2C of the door frame 2 and the auxiliary member 8 attached to the reinforcing member 7 coupled to the core member 5C, , the parallel function of the parallel means 45 allows the first connecting member 21 and the second connecting member 22 to be perpendicular to the vertical direction, which is the interval between the upper frame member 2C and the reinforcing member 7, and the thickness direction of the door frame 2. It is possible to make them parallel or substantially parallel while arranging them side by side in the horizontal direction.

Since only the first connecting member 21 of the second connecting device 20B is placed upward about the central axis 24 of the second connecting device 20B, the insertion work can be performed by a small number of workers. Workability can be improved and the work can be finished easily and in a short time.

After inserting the plurality of first connecting devices 20A into the horizontal spaces between the side frame members 2A and 2B and the reinforcing members 7 and the vertical spaces between the upper frame member 2C and the reinforcing members 7 as described above, , the operator moves at least one of the first connecting member 21 and the second connecting member 22 of each of the first connecting devices 20A to the other connecting member around the central axis 24 and moves the side frame member 2A. , 2B side and the upper frame member 2C side. For example, this rotating work is performed in the second hole 29 and the third hole 30 shown in FIG. 7 of the first connecting member 21 and in the second hole 38 and the third hole 39 shown in FIG. It can be implemented by inserting a tool or the like.

FIG. 14 is a cross-sectional view taken along line S14-S14 of FIG. 13 showing a side view of the first connector 20A after this pivoting operation has been performed. As shown in FIG. 14, when the above-described rotation operation is performed, the second connecting member 22 is provided on the second connecting member 22 and is in contact with the rear surface 27A of the bridging portion 27 of the first connecting member 21. As shown in FIG. The protruding piece 40 is bent from the connection point with the bridging portion 36 of the second connecting member 22 due to the load caused by the turning work by the operator, and as a result, the parallel function of the parallel means 45 disappears. For this reason, among the plurality of first connectors 20A, the first connector 20A inserted between the side frame members 2A and 2B and the reinforcing member 7 has the first connecting member 21 and the second connecting member 22. 10, the left-right direction M By rotating about the central axis 24 so that the inclination angles θ1 and θ2 with respect to the can be inserted into the auxiliary member 8 between the ends 26A and between the ends 35A on the side of the auxiliary member 8 shown in FIGS. 7 and 9 (see FIG. 15). Further, regarding the first connecting member 20A inserted in the space between the upper frame member 2C and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are inserted into the space between the upper frame member 2C and the reinforcing member 7. The two connecting portions 26 of the first and second connecting members 21 and 22 are rotated about the central axis 24 so that the inclination angles with respect to the vertical direction, which is the direction of , 35 can be inserted into the auxiliary member 8 between the ends 26A on the side of the auxiliary member 8 and between the ends 35A.

For this reason, in each first connector 20A, the first connecting member 21 is arranged in the direction of the gap between the side frame members 2A, 2B and the auxiliary member 8 and in the direction of the gap between the upper frame member 2C and the auxiliary member 8. The second connecting member 22 has an inclination angle with respect to the direction of the gap between the side frame members 2A and 2B and the auxiliary member 8 and the direction of the gap between the upper frame member 2C and the auxiliary member 8. , the inclination angle is opposite to the inclination angle of the first connecting member.

In addition, in these first connecting devices 20A, as described above, the second connecting member 22 has reduced-strength portions on both sides of the projecting piece portion 40 provided on the second connecting member 22. Since the two notch portions 41 are formed, even if the load of the above-described rotation work for bending the projecting piece portion 40 from the connecting portion with the bridging portion 36 of the second connecting member 22 is small, the operator can can bend the projecting piece 40 more reliably.

Further, in the present embodiment, the central shaft 24, which is a constituent member of the first connector 20A, rotates the first connection member 21 and the second connection member 22 of the first connector 20A. In addition, since the first connecting member 21 and the second connecting member 22 are commonly inserted through, the first connecting member 21 and the second connecting member 22 are rotatable. Compared to the case where the central shafts are separately provided in the first connecting member 21 and the second connecting member 22, the number of members constituting the first connecting member 20A can be reduced, thereby improving the structure. Simplification and lower manufacturing costs can be achieved.

15, as described above, between the ends 26A of the two connecting parts 26, 35 of the first and second connecting members 21, 22 of the first connecting tool 20A on the side of the auxiliary member 8 and the end 35A A state in which an auxiliary member 8 is inserted between them is shown.

After performing the work described above, the operator connects the ends of the first connecting members 21 of the first connecting member 20A on the auxiliary member 8 side to the two connecting members shown in FIGS. 4 and 13. 25 is inserted into the second hole 29 of FIG. , and each end of the second connecting member 22 on the side of the auxiliary member 8 connects the two couplers 34 shown in FIGS. 16 and 17 by inserting it into the second hole 38 of FIG.

In addition, as shown in FIG. 3, the operator removes the first connecting member 20B from each of the two second connectors 20B arranged at the bottom of the left and right side frame members 2A and 2B of the door frame 2, respectively. The connecting member 21 is rotated around the central axis 24, and the tilt angle of the first connecting member 21 with respect to the left-right direction M is set to the tilt angle θ1 of the first connecting member 20A with respect to the first connecting member 21. In the same or substantially the same way, the end of the first connecting member 21 on the side of the auxiliary member 8 is connected to the auxiliary member 8 by a fastener similar to the two fasteners 25 shown in FIGS. .

The reason why these second connectors 20B use the first connection member 21 and do not use the second connection member 22 is that they are arranged below the first connection member 21. This is because by omitting the second connecting member 22, the second connecting device 20B can be effectively arranged at the lowermost portions of the left and right side frame members 2A and 2B.

When the coupling work using the couplings 25 and 34 described above is performed, the door frame 2 is attached to each of the auxiliary members 8, and in the plurality of first couplings 20A, two coupling portions 26 of the first coupling member 21 and the Via the two connecting parts 35 of the two connecting members 22, and via the two connecting parts 35 of the first connecting member 21 in the two second connecting tools 20B. become. In this connecting work, the first connecting member 21 and the second connecting member 22 are connected to the first connecting member 21 and the second connecting member 22 for the first connecting member 20A inserted between the side frame members 2A and 2B and the reinforcing member 7. , 2B and the reinforcement member 7 with respect to the left-right direction M, which is the direction of the distance between them, are opposite to each other. are connected in a vertically immovable state. Further, in the connecting work, the first connecting member 21 and the second connecting member 22 of the first connecting member 20A inserted into the space between the upper frame member 2C and the auxiliary member 8 are reinforced with the upper frame member 2C. Since the inclination angles with respect to the vertical direction, which is the direction of the distance from the member 7, are opposite to each other, the door frame 2 is immovable in the horizontal direction with respect to the auxiliary member 8. are connected.

16 and 17, the ends of the first connecting members 21 of the first connecting device 20A on the auxiliary member 8 side are separated into two pieces shown in FIGS. 7 provided in each connecting portion 26 of the first connecting member 21, and when connected to the auxiliary member 8, as described in FIG. A load W from the coupler 25 acts on the end portion 26A of each connecting portion 26 on the auxiliary member 8 side. Therefore, the torsion angle 90°-α existing at the end portion 26A on the auxiliary member 8 side decreases or disappears due to the load W, and the twist angle 90°-α on the side opposite to the end portion 26A on the auxiliary member 8 side. At the end portion 26B on the side of the door frame 2, which is the end portion, a twist angle of 90°-β is generated as described above.

FIG. 18 is an enlarged cross-sectional view of the end portion 26B showing that such a twist angle of 90°-β occurs at the end portion 26B of the respective connecting portion 26 of the first connecting member 21 on the door frame 2 side. be.

For this reason, the corner 28A of the hole 28 is engaged with the surface of the central shaft 24. In other words, the central shaft 24 is a member to be engaged with which the corner 28A of the hole 28 is engaged, By locking the hole 28 to the locked member, the first connecting member 20</b>A having the first connecting member 21 as a constituent member moves in the thickness direction of the door frame 2 , which is the axial direction N of the central shaft 24 . becomes immobile. For this reason, the door frame 2 is connected to the auxiliary member 8, which is a building material on the building frame side, in an immovable state in the thickness direction of the door frame 2. As shown in FIG.

In particular, since the central shaft 24, which is the member to be locked in this embodiment, is a male threaded rod having a large number of irregularities formed alternately in the axial direction by threads and grooves on its surface, as described above, The corner portion 28A of the hole 28 is more reliably locked to the surface of the central shaft 24, thereby more reliably immobilizing the door frame 2 with respect to the auxiliary member 8 in the thickness direction of the door frame 2. It can be connected as a state.

Further, in this embodiment, the auxiliary member 8 to which the first and second connecting members 21 and 22 are connected by the above-described couplers 25 and 34 is attached to the door frame by the reinforcing member 7 by the positioning member 10 shown in FIG. Since the door frame 2 is positioned and attached at a predetermined position in the thickness direction of the door frame 2, the corner portion 28A of the hole 28 engages with the surface of the central shaft 24, so that the door frame 2 is positioned in the thickness direction of the door frame 2. is positioned and arranged at a predetermined position.

Further, in this embodiment, as described above, the load W of FIG. 8 by the coupler 25 of FIG. 8, the bridging portion 27 provided on the first connecting member 21 is provided with a direction protruding to the outside of the first connecting member 21 in the thickness direction of the bridging portion 27. In addition, a torsion angle of 90°-β is generated in the end portion 26B of each of the first connecting members 21 on the door frame 2 side. In the present embodiment, the bridging portion 27 is provided with the elongated hole 31 serving as a strength-reduced portion for reducing the strength of the bridging portion 27. Therefore, the load W causes the bridging portion 27 to bend. Such deformation will occur more reliably, and thus the twist angle 90°-β of the end portion 26B on the side of the door frame 2 will also occur more reliably.

In the embodiment described above, the ends 26A and 35A of the two connecting portions 26 and 35 of the first and second connecting members 21 and 22 of the first connecting tool 20A on the side of the auxiliary member 8 are connected to the auxiliary member 8. 16 and 17, the couplers 25 and 34, which are two each, are arranged on opposite sides of the central axis 24 in the axial direction N to In order to connect the ends 26A and 35A on the side of the auxiliary member 8 to the auxiliary member 8, the axial direction N of the central shaft 24 is opposite to each other.
