The locking portion can be locked to the locked member, and the locked member is perpendicular to the direction of the interval. A building material that is arranged in one of the two building materials in the thickness direction, and the bonding part is a building material that is bonded to the other of the two building materials by moving the bonding tool in the thickness direction, and the bonding part is not bonded to the foregoing In the state of the other building material, the locking portion can move in the thickness direction relative to the locked member, and the joining portion can be combined with the other building material by moving in the thickness direction using the coupling tool. After the locking portion moves in the direction having the vector in the thickness direction relative to the locked member and is locked to the locked member, the connecting member connects the two building materials.

According to this connecting tool, when the joining part is joined to the other building material among the two building materials by the joining tool, the locking part moves in the direction having the thickness direction vector relative to the locked member of the building material provided on one side. Therefore, the locking portion is locked to the locked portion, and the two building materials are connected by the connecting tool. Therefore, the two building materials arranged at a gap can be connected in a fixed state in the thickness direction orthogonal to the direction of the gap. In addition, the joining operation can be performed naturally by joining the joining part of the joining member provided in the joining tool to the building material of the other side with the joining tool. Moreover, the joining operation can be performed without using fire for welding. Therefore, the connection operation can be easily performed.

In one embodiment of the connecting device of the present invention, when the connecting portion is moved in the thickness direction by the connecting device, the locking portion is parallel to the thickness direction of the locked member. Moves in the direction of, and is locked by the aforementioned locked member. Alternatively, it may be configured that when the coupling portion is moved in the thickness direction by the coupling tool, the locking portion moves obliquely with respect to the locked member, and the locking portion is angularly locked to the The member is locked.

Therefore, the core member 5, the reinforcing member 7 and the strip member 8 are building materials on the side of the structure. In contrast, the hinged door 1 and the door frame 2 are members provided on the side of the hinged door device of the wall 4. Therefore, the hinged door 1 and the door frame 2 are building materials on the side where the hinged door device is located.

3 shows a state in which the door frame 2 is connected to the reinforcing member 7 via the nail strip member 8 by the connecting tool 20 after the operation of arranging the door frame 2 inside the opening 4A of the wall 4 is performed. For each of the side frame members 2A and 2B on the left and right of the door frame 2 and the upper frame member 2C, the connecting tools 20 are provided in plural corresponding to the strip members 8. Since each connecting device 20 has the same shape and structure as each other, in FIGS. 4 and 5, the connecting device 20C among the connecting devices 20A to 20J shown in FIG. 3 is shown as a representative example, and the connecting device 20C is installed on the door frame 2 side frame member 2A, and the side frame member 2A and the reinforcing member 7 joined to the aforementioned core member 5A are connected.

It can be seen from FIG. 5 that the supporting members 12 coupled to the side frame members 2A and 2B of the door frame 2 and the upper frame member 2C fix and support both ends of the pin-shaped locked member 21 in the longitudinal direction. The connecting tools 20A-20J are respectively attached to the door frame 2 by inserting the locked member 21 at the ends of the connecting tools 20A-20J located on the side of the door frame 2. The connecting devices 20A~20J are pre-installed on the door frame 2 in the workshop. On the other hand, the end of each connecting device 20A-20J on the side where the reinforcing member 7 is located is connected to the nail strip member 8 by means of the connecting device, namely the tail screw 30, at the construction site of the hinged door device. . Thereby, the door frame 2 that becomes the building material on the side of the hinged door device and the nail strip member 8 and the reinforcing member 7 that become the building material on the side of the structure are connected by the connecting tools 20A-20J.

In addition, the longitudinal direction of the pin-shaped locked member 21 is the thickness direction of the door frame 2 and the wall 4 orthogonal to the distance between the door frame 2 and the nail strip member 8 and the reinforcing member 7, that is, the left-right direction.

6A and 6B show a front view and a plan view of the connecting device 20. The connecting tool 20 has two connecting members 22 provided in the thickness direction of the door frame 2 and a straddling part 23 spanning the two connecting members 22. The span portion 23 is arranged between the connecting members 22 and is continuous with one of the upper and lower surfaces of the connecting members 22. Such a connecting device 20 is formed by stamping and bending of sheet metal. The end 22A of each connecting member 22 on the side where the door frame 2 is located protrudes from the straddle portion 23 toward the side where the door frame 2 is located. In addition, the end 22B of each connecting member 22 on the side where the reinforcement member 7 is located protrudes from the span portion 23 toward the side where the reinforcement member 7 is located. In addition, holes 24 are formed in each end 22A located on the side of the door frame 2. This hole 24 becomes an insertion part for inserting the pin-shaped member to be locked 21 shown in FIG. 5 inside. In addition, holes 25 are formed in each end 22B located on the side of the reinforcing member 7. The hole 25 becomes a coupling portion for coupling the end portion 23B to the nail strip member 8 with the self-drilling screw 30 shown in FIG. 5.

Furthermore, the inner diameter of the hole 24 which is a round hole is larger than the outer diameter of the pin-shaped member 21 to be locked, so it is configured to be able to insert the member 21 to be locked into the hole 24 in a floating state.

Two cut-in parts 26 and 27 are formed in the plate-shaped span part 23 along the direction of the distance between the door frame 2 and the reinforcing member 7. The two cut parts 26 and 27 are formed in the door frame in the span part 23 2 in the center of the thickness direction. Among the cut-in parts 26 and 27, the cut-in part 26 is cut from the end 23A of the straddle part 23 on the side where the door frame 2 is located to the side where the reinforcing member 7 is located. The cut-in portion 27 is cut from the end 23B on the side where the reinforcing member 7 is located in the straddle portion 23 to the side where the door frame 2 is located. Then, between the cut-in portions 26 and 27, a connecting portion 28 in the straddle portion 23 is formed. Therefore, the two connecting members 22 provided in the thickness direction of the door frame 2 are in a state of being connected by the connecting portion 28 provided in the span portion 23.

In addition, in the connecting tool 20 of the present embodiment, as shown in FIG. 6B, the end 22B of the two connecting members 22 located on the side of the reinforcing member 7 protrudes from the span portion 23 toward the side of the reinforcing member 7 Extend to the outside of the door frame 2 and the wall 4 in the thickness direction. Therefore, the end portions 22B located on the side of the reinforcing member 7 extend from the span portion 23 to the outer side of the door frame 2 and the wall 4 in the thickness direction.

In the coupling device 20 of the present embodiment having the above shape and structure, as shown in FIG. 6C, a load W toward the inner side of the thickness direction of the door frame 2 is applied to the end of the two coupling members 22 on the side of the reinforcing member 7 Therefore, when the end portions 22B are moved toward the inner side of the door frame 2 and the wall 4 in the thickness direction, the cut-in portion 27 will shrink and the cut-in portion 26 will expand, resulting in elastic deformation of the straddle portion 23. Therefore, the end 22A of the two connecting members 22 located on the side of the door frame 2 is rotated around the connecting portion 28 to the side opposite to the acting direction of the load W, that is, the outer side of the door frame 2 and the wall 4 in the thickness direction. Move.

In addition, the pin-shaped member to be locked 21 shown in FIG. 5 is formed of, for example, a bolt shaft with a male thread engraved on the surface. Therefore, the uneven portion 21A is formed on the surface of the locked member 21.

As mentioned above, the work of installing the connecting devices 20A-20J on the side frame members 2A, 2B and the upper frame member 2C of the door frame 2 shown in FIG. 3 is performed in the workshop. This operation is performed by inserting the locked member 21 shown in FIG. 5 into the inside of the hole 24 shown in FIGS. 6A, 6B, and 6C, and then fixing the support by welding. The supporting members 12 at the both ends of the locked member 21 in the longitudinal direction are connected to the side frame members 2A, 2B, and the upper frame member 2C of the door frame 2. The aforementioned holes 24 are formed in each of the connecting devices 20A to 20J. The end 22A of the member 22 on the side where the door frame 2 is located. When this operation is performed, the coupling tools 20A to 20J are arranged at the hole 24 in the side frame members 2A, 2B, and the upper frame member 2C. In addition, the connecting tools 20A-20J are free to rotate around the locked member 21, and the locked member 21 has a length dimension in the thickness direction of the door frame 2, so it is guided by the locked member 21 to be movable To the thickness direction of the door frame 2.

In this way, the connecting devices 20A-20J installed in the door frame 2 are transported to the construction site of the building where the hinged door installation is installed together with the door frame 2, and the door frame 2 is arranged in the construction installation of the hinged door installation as shown in Figure 3 In other words, it is arranged inside the opening 4A of the wall 4 shown in FIGS. 1 and 2.

Next, the operator rotates each of the connecting tools 20A-20J with the locked member 21 as the center, and then, as shown in FIG. 7, inserts the nail strip member 8 attached to the reinforcing member 7 into the connecting tool 20A~ The two connecting members 22 of 20J are located between the ends 22B on the side where the reinforcing member 7 is located. After inserting the nail sticking member 8 between the end portions 22B of the connecting member 22, insert the two holes 25 shown in FIG. 7 into the holes 25 provided in the end portions 22B, for example, as shown in FIGS. 6A, 6B and 6C. The front end of the self-drilling screw 30. After inserting the tip of the self-drilling screws 30 into the hole 25, the self-drilling screws 30 are rotated. In this way, the self-drilling screw 30 itself is used to form a female screw hole into which the self-drilling screw 30 can be screwed in the nail sticking member 8, and the self-drilling screw 30 is used to connect the end 22B to the nail sticking member 8. Thereby, the door frame 2, which is the building material on the side of the hinged door device, is connected to the reinforcing member 7 which is the building material on the side of the structure by the connecting tools 20A-20J via the nail sticking member 8.

In this embodiment, in the above operation, the holes 24 formed in the ends 22A of the two connecting members 22 provided in the connecting tools 20A-20J on the side of the door frame 2 are used to insert the locked member 21 Through the insertion part. In addition, the hole 25 at the end 22B of the two connecting members 22 provided on the connecting tools 20A to 20J on the side of the reinforcing member 7 serves as a connecting portion for connecting to the strip member 8 by the self-drilling screw 30. Furthermore, the self-drilling screw 30 serves as a coupling tool for coupling the coupling part to the nail strip member 8 which is the side building material of the structure.

In addition, the end 22B of the two connecting members 22 provided in the connecting tools 20A-20J on the side of the reinforcing member 7 is as shown in FIG. 6B and extends from the span portion 23 to the outer side of the door frame 2 in the thickness direction.

After the end 22B abuts on the strip member 8 by this movement, it is coupled to the strip member 8 by the self-drilling screw 30.

Then, when the end 22B of the two connecting members 22 on the side of the reinforcing member 7 moves toward the inner side of the door frame 2 and the wall 4 in the thickness direction until it abuts against the nail strip member 8, as shown in the description of FIG. 6C, the installation The end 22A of the two connecting members 22 of the connecting tools 20A-20J located on the side of the door frame 2 will be centered on the aforementioned connecting portion 28 by elastic deformation of the cross frame portion 23 formed with the cut-in portions 26 and 27 On the opposite side of the moving direction of the end portion 22B, that is, the outer side of the door frame 2 and the wall 4 in the thickness direction, a rotating motion of expanding movement is performed. Therefore, by the movement of the end portions 22A, the holes 24 provided in the end portions 22A move relative to the locked member 21. The movement of the hole 24 relative to the locked member 21 is generated by the hole 24 rotating around the connecting portion 28. Therefore, the two end portions 22A and the holes 24 provided at the end portions 22A are facing relative to The longitudinal direction of the locked member 21 moves in a direction having an inclination angle, that is, a direction having a vector of the thickness direction of the door frame 2 and the wall 4 which becomes the direction of the longitudinal dimension of the locked member 21.

FIG. 5 shows the connecting device 20C among the connecting devices 20A to 20J when the two end portions 22B are connected to the nailing strip member 8 using the two self-drilling screws 30 as described above. In addition, in FIG. 8, the relationship between the hole 24 formed at the end 22A of the two connecting members 22 of the connecting tools 20A to 20J at this time and the locked member 21 is shown in a plane section. As described above, since the end 22A or the hole 24 moves in a direction having an oblique angle with respect to the thickness direction of the door frame 2 and the wall 4, that is, the longitudinal direction of the locked member 21, in other words, it is relative to the locked member 21. As it moves obliquely, the inner peripheral surface corners 24A and 24B of the hole 24 are locked on the surface of the locked member 21 at an angle. In particular, in the present embodiment, as described above, since the uneven portions 21A are formed on the surface of the locked member 21, the inner peripheral surface corners 24A of the hole 24 are formed by the hooks of the uneven portions 21A. 24B is more securely locked to the surface of the locked member 21.

Therefore, the hole 24 serves as an insertion portion through which the locked member 21 penetrates into the interior, and at the same time serves as a locking portion provided in the coupling tools 20A to 20J to be locked with the locked member 21 in this embodiment. After the inner peripheral surface corners 24A and 24B of the hole 24 are locked to the uneven portion 21A on the surface of the locked member 21, the locking action of the locked member 21 by the locking portion causes the connecting tool 20A~ 20J cannot move along the locked member 21. Therefore, the door frame 2 and the reinforcing member 7 and the nail strip member 8 arranged at intervals are perpendicular to the direction of the distance between the door frame 2 and the reinforcing member 7 and the nail strip member 8 by the connecting tools 20A-20J. The direction of the door frame 2 and the thickness direction of the wall 4 are connected in an immobile state.

Furthermore, according to this embodiment, two of the connecting members 22 of the connecting tools 20A to 20J are moved toward the inner side of the door frame 2 and the wall 4 in the thickness direction of the end 22B on the side of the reinforcing member 7 by the self-drilling screw 30 , When the end portions 22B are combined with the nail strip member 8, the two end portions 22A located on the side of the door frame 2 in each of the connecting members 22 of the connecting device 20A-20J move in the thickness direction of the door frame 2 and the wall 4 The movement of the outside, that is, the movement in the direction having the longitudinal component of the locked member 21, the corners 24A and 24B of the inner peripheral surface of the hole 24 provided at the ends 22A are locked to the locked member 21. Thereby, the door frame 2 is connected with the reinforcing member 7 and the nail strip member 8 by the connecting tools 20A to 20J, so the connecting operation can be easily performed without using fire for welding.

Moreover, in this embodiment, as shown in FIG. 3, between the door frame 2 and the reinforcement member 7 and the nail|sticker strip member 8, a plurality of connecting tools 20A-20J are arranged. Among the connecting devices 20A-20J, the connecting devices 20A-20D, 20G-20J are arranged in the direction orthogonal to the following two directions, namely the vertical direction. The aforementioned two directions are the door frame 2 and the reinforcing member 7 and the nails. The direction of the spacing between the bar members 8 and the thickness direction of the door frame 2 and the wall 4. Among the connecting devices 20A-20D, 20G-20J, the connecting devices 20A, 20B, 20G, 20H and the connecting devices 20C, 20D, 20I, 20J are relative to the door frame 2 and the reinforcing member 7 and the nail strip member 8. The direction of the interval, that is, the left-right direction, and the inclined direction are opposite to each other. Therefore, the door frame 2 is also in an immobile state in the vertical direction, and the reinforcing member 7 and the nail sticking member 8 are connected. The aforementioned reinforcing member 7 and the nail sticking member 8 are in the left-right direction with the left and right side frame members 2A, 2B of the door frame 2. Opposite configuration.

Furthermore, the connecting tools 20A, 20B, 20G, and 20H can make the straddle part 23 be used downward, and the coupling tools 20C, 20D, 20I, and 20J can make the straddle part 23 be used upward as shown in FIG. 4.

Furthermore, as shown in FIG. 3, the upper frame member 2C of the door frame 2, the reinforcement member 7 which opposes this upper frame member 2C up and down, and the strip member 8 are connected by the connection tool 20E, 20F. In these connecting tools 20E and 20F, the direction of the space between the upper frame member 2C and the reinforcing member 7 and the nail strip member 8, that is, the directions inclined in the vertical direction are opposite to each other. Therefore, the door frame 2 is also connected to the reinforcing member 7 and the tack member 8 in a stationary state in the left-right direction.

In addition, as described above, the coupling tool for coupling the end 22B on the side of the reinforcing member 7 of the two coupling members 22 of the coupling tools 20A to 20J to the nail strip member 8 is the self-drilling screw 30. The self-drilling screw 30 can form a female screw hole in the nail stick member 8 for the self-drilling screw 30 to be screwed in by the self-drilling screw 30. Therefore, the respective connecting tools 20A-20J are centered on the locked member 21 After being rotated to an arbitrary angle, the end 22B can be connected to the nail strip member 8 by the self-drilling screw 30. Therefore, among the connecting tools 20A-20J, the position of the door frame 2 can be adjusted in the left-right direction by the rotation angle centering on the locked member 21 of the connecting tools 20A-20D and the connecting tools 20G-20J. In addition, the position where the door frame 2 is arranged can be adjusted in the vertical direction by the rotation angle centered on the locked member 21 of the coupling tools 20E and 20F.

Furthermore, as described above, since the positioning member 10 is attached to the nail strip member 8, the positioning member 10 can position the position of the nail strip member 8 in the thickness direction of the door frame 2 in the reinforcing member 7, so that the door frame can be The arrangement position of 2 is set at a predetermined position in the thickness direction of the door frame 2.

Figure 9 shows another embodiment of the connecting device. In this embodiment, the supporting member 112 attached to the side frame members 2A, 2B and the upper frame member 2C of the door frame 2 (only the side frame member 2A is shown in FIG. 9) has two pin-shaped locked members Both ends in the longitudinal direction of 21 are fixedly supported, so that the locked members 21 are inserted into the holes 24 formed at the ends 22A on the side of the door frame 2 in the respective connecting members 22 of the two connecting devices 20, and The directions inclined with respect to the direction of the distance between the door frame 2 and the reinforcing member 7 and the nail strip member 8 are opposite to each other, and the connecting device 20 is arranged between the door frame 2 and the reinforcing member 7 and the nail strip member 8.

According to this embodiment, it is possible to manage and process the connecting tools 20 that are inclined to the direction of the distance between the door frame 2 and the reinforcing member 7 and the nail strip member 8 in opposite directions. Therefore, the management and handling of these connecting devices 20 can be simplified in a workshop or a hinged door construction installation site.

In each of the embodiments described above, the tape member 8 is shorter than the reinforcing member 7 in size, but the tape member may be made into a long penetration member like the reinforcing member 7. In addition, the positioning member 10 may be omitted. Industrial availability
