It is a work to make it immovable with respect to the building side building material, and by this work, the opening frame is perpendicular to the building side building material, which is the direction of the interval between the building side building material and the opening frame. It is required to be immobile in the thickness direction.

  An object of the present invention is to connect two building materials that are arranged with a gap in an immovable state in the thickness direction orthogonal to the direction of the gap, and to connect the building materials that facilitates this joining work. A tool, a connection structure thereof, and a connection method thereof are provided.

  The building material connecting tool according to the present invention is a building material connecting tool for connecting two building materials arranged at an interval, wherein one of the two building materials has the above-mentioned spacing. The locking portion that is movable and lockable in the thickness direction with respect to the locked member that is arranged with the thickness direction orthogonal to the direction as the length direction is provided on the one building material side. Of the two building materials, a joining portion that is provided at the end and is joined to the other building material by moving the joining member in the thickness direction with respect to the other building material is the other building material side. A coupling part provided at an end of the coupling part, and the coupling part of the coupling part is coupled to the other building material by the coupling tool, so that the locking part of the coupling part is engaged with the engaged part. The locked member is moved by moving in the direction having the component in the thickness direction with respect to the stop member. The locking portion has a lockable, is characterized in that for connecting the two building materials by the locking.

  According to this connecting tool, when the connecting portion of the two building materials, which is connected to the other building material by moving in the thickness direction with respect to the other building material, is connected to the other building material by the connecting tool. , The locking portion is locked to the locked portion by moving in a direction having a component in the thickness direction with respect to the locked member provided on one of the building materials, Since the two building materials are connected by the connecting tool, it is possible to connect the two building materials arranged with a gap in a stationary state in the thickness direction orthogonal to the direction of the gap. In addition, this connecting work can be automatically performed by connecting the connecting portion provided in the connecting portion of the connecting member to the other building material with the connecting member, and can be performed without using fire for welding. , The work can be done easily.

  In this connecting tool, the locking portion can be locked to the locked member by moving the locking portion in the direction having the component in the thickness direction with respect to the locked member as described above. The locking part may be locked to the locked member by moving the locking part in a direction parallel to the thickness direction of the locked member, or the locking part. It is also possible that the locking portion can be locked to the locked member at an angle by moving diagonally with respect to the locked member.

  According to the latter, when the locking portion is locked to the locked member, the locking portion makes an angle with respect to the locked member, so that the locking portion can be locked more reliably with respect to the locked member. It can be something.

  Further, the direction in which the locking portion moves with respect to the locked member may be the same direction in the thickness direction as the direction in which the coupling portion moves relative to the other building material by the coupling tool, or the coupling portion may move in the other direction by the coupling tool. The direction opposite to the moving direction of the building material in the thickness direction may be used.

  Further, in the connector according to the present invention, the number of the connecting portions in the thickness direction may be one or may be a plurality.

  Furthermore, when the number of connecting portions in the thickness direction is two, a bridging portion may be provided between the connecting portions so as to bridge the two connecting portions.

  In this way, when the number of connecting portions in the thickness direction is two and the connecting portion is a bridging portion bridging the two connecting portions, the bridging portion is plate-shaped. In addition, between the two connecting portions, the bridging portion may be provided with a cut portion in which the direction of the gap between the two building materials is the cut direction.

  According to this, when the connecting parts of the respective connecting parts are moved to the opposite direction in the thickness direction by the connecting tool and connected to the other building material, the respective locking parts are engaged by the action of the notch part. With respect to the stop member, it is a movement in the opposite direction in the thickness direction, and the coupling means causes a movement in the opposite direction to the direction in which the coupling portion moves with respect to the other building material, and Since these locking portions are locked to the locked member, the two building materials can be connected by the connecting tool.

As described above, the hinged door device is installed and installed, in other words, located inside the opening 4A of the wall 4 shown in FIGS. 1 and 2.

  Next, the worker rotates each of the connecting tools 20A to 20J about the locked member 21. As a result, as shown in FIG. 7, the connecting tools 20A to 20J are provided on the connecting tools 20A to 20J. The base member 8 attached to the reinforcing member 7 is inserted between the end portions 22B of the individual connecting portions 22 on the reinforcing member 7 side, and the base members 8 attached to the end portions 22B are inserted into the holes 25 of FIG. After inserting the tips of the two drill screws 30 shown in FIG. 1, by rotating these drill screws 30, female screw holes into which the drill screws 30 are screwed are formed in the base member 8 by the drill screws 30 themselves, and the ends are formed. The portion 22B is connected to the base member 8 with the drill screw 30. As a result, the door frame 2 that is the hinged door device-side building material is connected to the reinforcing member 7 that is the skeleton-side building material through the base member 8 by the connectors 20A to 20J.

  In the present embodiment, the above-described work is performed so that the hole 24 formed in the end portion 22A on the door frame 2 side of the two connecting portions 22 provided in the connecting tools 20A to 20J causes the locked member 21 to move. The hole 25 formed in the end portion 22B on the reinforcing member 7 side of the two connecting portions 22 provided in the connecting tools 20A to 20J is a drill screw. It is performed as a connecting portion for connecting to the base member 8 by 30. Further, the drill screw 30 serves as a connecting tool for connecting the connecting portion to the base member 8 which is a building side building material. Has been done.

  Further, as shown in FIG. 3, the upper frame member 2C of the door frame 2 and the reinforcing member 7 and the base member 8 vertically opposed to the upper frame member 2C are connected by connecting tools 20E and 20F. In these connector 20E and connector 20F, the directions inclined with respect to the vertical direction, which is the direction of the spacing between the upper frame member 2C and the reinforcing member 7 and the base member 8, are opposite to each other. Is becoming Therefore, the door frame 2 is immovable in the left-right direction and is connected to the reinforcing member 7 and the base member 8.

  Further, as described above, the coupling tool for coupling the end portion 22B on the reinforcing member 7 side of the two coupling portions 22 of the coupling tools 20A to 20J to the base member 8 is the drill screw 30, and the drill screw 30. Since the female screw hole into which the drill screw 30 is screwed can be formed in the base member 8 by rotating the respective connecting tools 20A to 20J about the locked member 21 to an arbitrary angle. Then, the end portion 22B can be joined to the base member 8 by the drill screw 30. Therefore, the position where the door frame 2 is arranged is adjusted in the left-right direction by the rotation angle of the coupling tools 20A to 20J around the locked member 21 of the coupling tools 20A to 20D and the coupling tools 20G to 20J. Further, the position where the door frame 2 is arranged can be adjusted in the vertical direction by the rotation angle of the coupling tools 20E and 20F about the locked member 21.
