Therefore, in the connection work of the two building materials carried out as described above, the connecting member, which is a constituent member of the connecting tool for building materials, is arranged on one of the two building materials. The work for directing the connecting member to the other building material side by rotating around the other building material and the work for connecting the connecting member to the other building material with a binder can be performed with improved workability. Is required.

An object of the present invention is an operation for directing a connecting member of a connecting tool for building materials toward the other building material side by rotating about a central axis arranged on one of the two building materials. It is an object of the present invention to provide a method for connecting a building material so that the work for connecting the connecting member to the other building material by a binder can be performed with improved workability.

The building material connecting work method according to the present invention is a building material connecting work method for connecting two building materials arranged at intervals by a building material connecting tool arranged between these building materials. The connecting tool for building materials includes a central axis arranged on one of the two building materials with the thickness direction of the one building material as the axial direction, and both ends in the length direction. Of these, one end on the building material side is configured to include at least one connecting member that is rotatable about the central axis, and the length direction of the at least one connecting member. In the method of connecting building materials, in which the other end of the other end of the building material side is joined to the other building material with a connecting tool to connect the two building materials with the building material connecting tool. The first work step for turning the direction of at least one connecting member toward the other building material side by rotating the at least one connecting member around the central axis with an operation tool. To connect the other end of the at least one connecting member to the other building material with the coupling tool while pressing the at least one connecting member toward the other building material side with the operating tool. It is characterized by including a second work step.

As described above, in the building material connecting work method according to the present invention, the direction of the at least one connecting member is rotated around the central axis of the at least one connecting member to move to the other building material side. The other end of the at least one connecting member is joined to the other building material by a binder while pressing the at least one connecting member toward the other building material. The second work step for this is performed by using the same operating tool, and therefore, the work of connecting the two building materials with the connecting tool for building materials can be carried out with improved workability.

Further, in the above-mentioned method for connecting building materials according to the present invention, in the second work step, the at least one connecting member is pressed toward the other building material by an operation tool, and the at least one connecting member is said to be connected. Since the work step is to connect the other end to the other building material with a coupling tool, even if the one end portion of the at least one connecting member is rotatable about the central axis, the coupling tool is used. This joining operation can be performed while preventing the at least one connecting member from making slight movements such as swinging around the central axis.

Further, in the building material connecting work method according to the present invention, the first working step is performed by using the at least one connecting member in the spacing direction of the two building materials and the thickness direction of the one building material from the central axis. By pressing from the one building material side to the other building material side at a position separated in a direction orthogonal to the above, the work process of rotating the at least one connecting member around the central axis is performed. In the second work step, while pressing the portion of the at least one connecting member toward the other building material, the other end of the at least one connecting member is attached to the other building material by the coupling tool. The work process to be combined may be performed, and the operation tool may continue to press the portion of the at least one connecting member from the start of the first work process to the end of the second work process, or the first step. An interrupted work step may be provided between the first work step and the second work step, for example, for the worker to perform another work.

Of these, according to the former, from the start of the first work process to the end of the second work process, the operation tool keeps pressing the portion of the at least one connecting member toward the other building material side. , The first work process and the second work process can be carried out as a continuous and consistent work, which also improves the workability of the work related to these first work process and the second work process. It will be possible to carry out.

In the second work step, the coupling tool for connecting the other end of the at least one connecting member to the other building material is the other end of the at least one connecting member and the other building material. The other end of the at least one connecting member may be connected to the other building material by being inserted into the holes provided in both of the above, or the at least one connecting member. Of the other end portion and the other building material, at least the other building material may be threaded to join the other end portion of the at least one connecting member to the other building material.

Of these, according to the latter, the other end of the at least one connecting member can be joined at any point on the other building material by the coupling tool that drills holes in the other building material. Further, at the time of this joining operation, since the at least one connecting member is pressed toward the other building material side by the operation tool, the at least one connecting member is formed when the other building material is threaded. It is possible to carry out this thread cutting hole processing by preventing fine movements such as swinging around the central axis.

Further, in the above-mentioned method for connecting building materials according to the present invention, the number of at least one connecting member may be two. When the number of connecting members is two in this way, the operation tool is used to rotate the two connecting members around the central axis in the first work process, and in the second work process, the two connecting members are rotated around the central axis. The two connecting members will be pressed toward the other building material side.

Further, when the number of the at least one connecting member is two, the number of the connecting member for the building material is two before the two connecting members are rotated about the central axis. Two connecting members are arranged on opposite sides of the central axis in a direction orthogonal to the spacing direction of the building materials and the thickness direction of the one building material, and these connecting members are parallel or substantially parallel to each other. A parallel means having a parallel function may be provided, or such a parallel means may not be provided.

Of these, before the two connecting members were rotated around the central axis on the building material connecting tool as in the former, the direction in which the two building materials were spaced apart and the direction in which one of the building materials was thick. When a parallel means having a parallel function is provided in which two connecting members are arranged on opposite sides of the central axis in a direction orthogonal to the central axis to make these connecting members parallel or substantially parallel to each other. In the first work step, the parallel function of the parallel means is extinguished by rotating the two connecting members around the central axis with the operating tool.

The parallel means provided in the connecting tool for building materials has a parallel function in which two connecting members are arranged on opposite sides of the central axis to make these connecting members parallel or substantially parallel. In one work process, any method and structure may be used as long as the parallel function can be extinguished by rotating the two connecting members around the central axis with an operation tool. An example of the parallel means is a projecting piece portion that is provided on one of the two connecting members so as to project toward the other connecting member and is in contact with the other connecting member. The projecting piece portion may be bent and deformed by a pressing force applied to at least one of the two connecting members, and the parallel function may be extinguished by this bending deformation.

Further, the parallel means of another example is a friction means interposed between the two connecting members, and the frictional force of the friction means acts as a parallel function to move the two connecting members with respect to the central axis. These connecting members can be arranged parallel to each other or substantially parallel to each other, and a pressing force larger than the frictional force is applied to at least one of the two connecting members. Therefore, the parallel function may be extinguished.

Further, the parallel means of another example is a concavo-convex means formed by a concave portion formed in one of the two connecting members and a convex portion formed in the other connecting member and fits detachably in the concave portion. There is, a parallel function is generated by fitting the convex portion in the concave portion, and the two connecting members are arranged on opposite sides to the central axis so that the connecting members are parallel or substantially parallel to each other. At the same time, the parallel function may be extinguished by applying a pressing force to at least one of the two connecting members so that the convex portion escapes from the concave portion.

Further, in the method for connecting building materials according to the present invention, when the number of the at least one connecting member is two, the operating tool is provided with two pressing portions. The first work step and the second work step may be carried out by pressing the two connecting members with the two pressing portions.

When the number of the at least one connecting member is two, the number of the central axes may be one common to the two connecting members, or two. Each of the connecting members may be individual, and two may be arranged side by side in a direction orthogonal to the spacing direction of the two building materials and the thickness direction of one of the building materials. When the number of central shafts is one that is common to the two connecting members, the number of members of the building material connecting tool that is configured with the central shaft as a constituent member is reduced. The structure of the connecting tool for building materials can be simplified.

When the number of the at least one connecting member is two as described above, the two connecting members are oriented so as to be inclined to the opposite sides with respect to the spacing direction of the two building materials. The two building materials may be connected to each other, or the two building materials may be connected in parallel or substantially parallel to the spacing direction of the two building materials.

Further, the method for connecting building materials according to the present invention can also be carried out when the number of the at least one connecting member is one. In this way, when the number of the at least one connecting member is one, the operating tool is used to rotate one connecting member about the central axis in the first work step, and the second In the work process, one connecting member is pressed toward the other building material side.

Then, when the number of the at least one connecting member is one as described above, the operation tool is provided with two pressing portions, and the first work step and the second work step are two. It may be carried out by pressing one connecting member by one pressing portion among the pressing portions of the above. According to this, the number of the at least one connecting member is one for the operation tool used for operating the connecting tool for building materials in which the number of the at least one connecting member is two. It can also be used to operate a connecting tool for building materials, and can also be used as an operating tool.

When the number of the at least one connecting member is one, the one connecting member connects the two building materials in an inclined direction with respect to the spacing direction of the two building materials. It may be one, or it may be one that connects two building materials in parallel or substantially parallel to the spacing direction of the two building materials.

Further, even when the number of the at least one connecting member is two, or even when the number of the at least one connecting member is one, the method for connecting building materials according to the present invention is carried out. A cut may be formed in the operating tool used for the purpose, and the first work step and the second work step may be carried out by inserting the central axis into the cut portion. According to this, the first work step and the second work step can be easily carried out with little or no influence of the central axis.

Further, when the central shaft is supported by the bearing member and the bearing member is connected to the one building material so that the central shaft is arranged on the one building material, the first work step and the second work step and the second. The work process may be carried out by inserting a bearing member into the notch formed in the operating tool. According to this, the first work step and the second work step can be easily carried out without being influenced by or hardly affected by the bearing member.

The method for connecting building materials according to the present invention described above can be applied to any two building materials connected by a connecting tool for building materials. An example of these building materials is a building material on the skeleton side such as a wall and an opening frame arranged so as to face the building material in the left-right direction. The opening frame may be a door frame for a hinged door device or a sliding door. It may be a door frame for the device, an opening frame for a passage opening formed in the wall, and one of the two building materials is a fire door that is normally open. A door pocket or the like provided on the wall for storage may be used. Further, the method of connecting building materials according to the present invention can also be used to connect two building materials such as columns including intermediate columns of a building, beams, cross rails, face materials, etc., and applicable building materials are It is optional.

However, the shape of each of the two connecting portions 26 at the end portion 26A on the side of the auxiliary member 8 is open to the outside of the first connecting member 21 due to the above-mentioned twist angle α, in other words. , It has a V shape that opens outward in the axial direction N of the central axis 24.

In FIG. 8, in order to connect the end portion 26A on the auxiliary member 8 side of the connecting portion 26 to the auxiliary member 8 by the coupling tool 25 of FIG. 4, the central shaft 24 is attached to each end portion 26A on the auxiliary member 8 side. It shows the time when the loads W in the opposite directions in the axial direction N act. When such a load W acts on the end portion 26A on the side of each auxiliary member 8, the twist angle α shown in FIG. 7 of the end portion 26A on the side of each auxiliary member 8 decreases or disappears, and the bridging portion 27 Due to the influence of the load W, in the thickness direction of the bridging portion 27 (the thickness direction of the entire first connecting member 21), the first connecting member 21 is deformed in the direction of projecting outward. Is generated, and the end 26B on the side of each door frame 2 connected to the end 26A on the auxiliary member 8 side via the intermediate portion 26C has an axial direction N of the central shaft 24 due to the influence of the load W. A twist angle β, which is an inward inclination angle of the first connecting member 21, is generated, and this twist angle β is a twist angle in opposite directions with respect to the end portions 26B on the door frame 2 side.

As a result, in the entire first connecting member 21, the shape of the end portion 26B on the door frame 2 side of each of the two connecting portions 26 is closed to the inside of the first connecting member 21 due to the twist angle β. It becomes an inverted C shape.

Since the bridging portion 27 is provided with an elongated hole 31 which is a strength reducing portion for reducing the strength of the bridging portion 27, the bridging portion 27 is largely described above due to the load W. Therefore, the twist angle α of the end portion 26A on the auxiliary member 8 side is reduced or disappeared, and the twist angle β is further generated at the end portion 26B on the door frame 2 side. It is sure to occur.

The overall shape is substantially U-shaped due to the bridging portion 36 bridged over the 35. Further, each connecting portion 35 has a length dimension in a direction orthogonal to the axial direction N of the central axis 24 and also orthogonal to the thickness direction of the entire second connecting member 22, and this length dimension is a length. Both ends 35A and 35B in the direction have dimensions that reach the door frame 2 and the auxiliary member 8 that is the skeleton of the wall 4.

Of these end portions 35A and 35B, the end portion 35B on the door frame 2 side is provided with a large-diameter first hole 37 as an insertion portion for inserting the central shaft 24. Since the end portion 35A on the auxiliary member 8 side is provided with a second hole 38 having a small diameter as an insertion portion for inserting the coupling tool 34 shown in FIG. 4, the second hole 38 is provided. The end portion 35A on the auxiliary member 8 side is a coupling portion in the second connecting member 22 that is coupled to the auxiliary member 8 by the coupling tool 34. Further, each connecting portion 35 is also provided with a third hole 39 for inserting a coupling tool 51 which is a tapping screw, as will be described later in FIGS. 20 and 21.

Further, among both ends of the connecting portion 36 in the length direction of the connecting portion 36, the end portion 36B on the door frame 2 side projects toward the central shaft 24 side, in other words, toward the first connecting member 21 side. A projecting piece portion 40 is formed. The end portion 36B of the bridging portion 36 is provided with a notch portion 41 at a position close to the projecting piece portion 40, and in the present embodiment, the notch portion 41 is provided with end portions 36B on both sides of the projecting piece portion 40. Two are provided in. As shown in FIG. 9B, the projecting piece portion 40 of the present embodiment is formed by being slightly bent inward from the bridging portion 36 in the thickness direction of the second connecting member 22. ..

When a load in the thickness direction of the entire second connecting member 22 is applied to the projecting piece portion 40 formed on the second connecting member 22 in this way, the projecting piece portion 40 is bent in the thickness direction. It is deformable, and in this bending deformation, two notches 41 are provided at the end 36B of the bridge 36 on both sides of the projecting piece 40, and these notches 41 are bridged. Since it is a strength reducing portion for reducing the strength of the base end portion of the projecting piece portion 40 in the portion 27, it easily occurs, and even if the load is small, the projecting piece portion 40 can be easily bent and deformed. You can do it.

Further, the second building material connecting tool 20B shown in FIG. 3 includes a first connecting member 21, a bearing member 23, and a central shaft 24. Therefore, the second building material connecting tool 20B is a first building material connecting tool. It has the same structure as the one in which the second connecting member 22 is removed from 20A. In such a second building material connector 20B, the end portion 23A of the bearing member 23 is joined to the left and right side frame members 2A and 2B of the door frame 2 by welding or the like, so that the door frame 2 is also used at the factory.

Regarding the first building material connecting tool 20A inserted at a distance in the left-right direction between the auxiliary member 8 attached to the member 7, as described above, the parallel function of the parallel means 45 or the first connecting member 21 By contacting the connecting portion 27 of the above with the connecting portion 23C of the bearing member 23, the first connecting member 21 and the second connecting member 22 are spaced apart from the side frame members 2A and 2B and the auxiliary member 8. In the vertical direction, which is orthogonal to the horizontal direction and the thickness direction of the door frame 2, they are arranged on opposite sides to the central axis 24 so as to be parallel or substantially parallel to each other. The whole or substantially the entire 1 and 2nd connecting members 21 and 22 can be housed within the width dimension of the side frame member 2A in the left-right direction. Further, regarding the first building material connector 20A inserted at a vertical interval between the upper frame member 2C of the door frame 2 and the auxiliary member 8 attached to the reinforcing member 7 connected to the core member 5C. The first connecting member 21 and the second are due to the parallel function of the parallel means 45, or by the connecting portions 27 and 36 of the first and second connecting members 21 and 22 abuting on the connecting portion 23C of the bearing member 23. The central axis 24 of the connecting member 22 is arranged in the vertical direction, which is the direction of the distance between the upper frame member 2C and the auxiliary member 8, and in the horizontal direction, which is the direction orthogonal to the thickness direction of the door frame 2. By arranging them on opposite sides to each other so as to be parallel or substantially parallel to each other, all or substantially the entire first and second connecting members 21 and 22 are within the vertical width dimension of the upper frame member 2C.

Further, for a second building material inserted at a distance in the left-right direction between the side frame members 2A and 2B of the door frame 2 and the auxiliary member 8 attached to the reinforcing member 7 connected to the core members 5A and 5B. As for the connecting tool 20B, as shown in FIG. 13, the connecting portion 27 of the first connecting member 21 is brought into contact with the connecting portion 23C of the bearing member 23, so that the entire first connecting member 21 or the connecting portion 20B is brought into contact with the connecting portion 23C. Almost the entire side frame member 2A can be housed within the width dimension in the left-right direction.

Therefore, as described above, the first connecting member 21 and the second connecting member 22 of the first building material connecting tool 20A are rotatable about the central shaft 24, and the side frame members 2A and 2B and the auxiliary member are Even if the distance between the upper frame member 2C in the left-right direction and the distance between the upper frame member 2C and the auxiliary member 8 in the vertical direction are small, the connection for the first building material attached to the door frame 2 at these intervals. The tool 20A can be effectively inserted, and the first connecting member 21 of the second building material connecting tool 20B is rotatable about the central axis 24, and the side frame members 2A and 2B and the auxiliary member 8 are formed. Even if the distance between the door frame and the door frame 2 in the left-right direction is small, the second building material connector 20B attached to the door frame 2 can be effectively inserted, and this insertion work can be performed by a small number of workers. Can be improved easily and in a short time.

As described above, the plurality of first building material connecting tools 20A are arranged in the left-right direction between the side frame members 2A and 2B and the auxiliary member 8 and in the vertical direction between the upper frame member 2C and the auxiliary member 8. After inserting the second building material connector 20B at the interval and inserting the second building material connector 20B at the lateral interval between the side frame members 2A and 2B and the auxiliary member 8, the operator is shown in FIGS. 22 to 25. By using the operation tool 60 according to the embodiment of the present invention, the first building material connector 20A is arranged on the opposite side of the central axis 24 and is parallel or substantially parallel to each other. By rotating the first connecting member 21 and the second connecting member 22 about the central axis 24, as shown in FIG. 15, which is a cross-sectional view taken along the line S15-S15 of FIG. 14, the connecting tool for the first building material. The work of bending 20A into a dogleg shape is performed. In this bending operation work, the angle formed by the first connecting member 21 and the second connecting member 22 about the central axis 24 is made smaller than the angle in FIG. 12, so that the first connecting member 21 and the second connecting member 21 and the second connecting member 21 are formed. 2 The work is to turn each of the connecting members 22 toward the auxiliary member 8 side of the wall 4, and by the bending operation work, the tips of the first connecting member 21 and the second connecting member 22 are made of the building material on the wall 4 side. It comes into contact with the above-mentioned reinforcing member 7 to which the auxiliary member 8 is attached.

The work of bending the first building material connector 20A into a dogleg shape using the operation tool 60 will be described later. Further, the first connecting member 21 of the connecting tool 20B for the second building material is also rotated around the central shaft 24 by the work described later using the operating tool 60, and the direction of the first connecting member 21 is also the direction of the wall 4. It will be directed to the auxiliary member 8 side (see FIG. 32), and by this rotation operation, the tip of the first connecting member 21 of the second building material connecting tool 20B is also reinforced to which the auxiliary member 8 is attached. It comes into contact with the member 7.

When the first building material connecting tool 20A is bent in the dogleg shape shown in FIG. 15, as shown in FIG. 15, the first connecting member 20A is provided on the second connecting member 22. The projecting piece portion 40 that was in contact with the back surface 27A of the connecting portion 27 of the 1 connecting member 21 is bent from the connecting portion of the second connecting member 22 with the connecting portion 36 due to the load of the bending operation work by the operation tool 60. It is deformed, and as a result, the parallel function of the parallel means 45 described above disappears. Therefore, among the plurality of first building material connecting tools 20A, the first building material connecting tool 20A inserted at the interval between the side frame members 2A and 2B and the auxiliary member 8 is the first connecting member. 21 and the second connecting member 22 are between the side frame members 2A and 2B and the reinforcing member 7, as can be seen from the first connecting member 21 and the second connecting member 22 shown by the alternate long and short dash line in FIG. By rotating around the central axis 24 so that the tilt angles θ1 and θ2 with respect to the left-right direction M, which is the direction of the interval between the two, are the same or substantially the same magnitude in opposite directions, the first and the first of these. The two connecting portions 26, 35 of the second connecting members 21 and 22 are inserted into the auxiliary member 8 between the end portions 26A on the auxiliary member 8 side shown in FIGS. 7 and 9 and between the end portions 35A. Can be done (see FIG. 16). Further, regarding the connecting tool 20A for the first building material inserted at the interval between the upper frame member 2C and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are separated from the upper frame member 2C and the reinforcing member. In these first and second connecting members 21, 22 The two connecting portions 26, 35 can be inserted into the auxiliary member 8 between the end portions 26A on the auxiliary member 8 side and between the end portions 35A.

Therefore, in each of the first building material connecting tools 20A, the first connecting member 21 is in the direction of the distance between the side frame members 2A and 2B and the auxiliary member 8, and 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 interval between the two members, and the second connecting member 22 has the direction of the interval between the side frame members 2A and 2B and the auxiliary member 8 and the upper frame member 2C and the auxiliary member 8. The tilt angle with respect to the direction of the interval between them forms a tilt angle opposite to the tilt angle of the first connecting member.

In these first building material connecting tools 20A, as described above, the second connecting member 22 serves as strength reducing portions on both sides of the projecting piece portions 40 provided on the second connecting member 22. Since the two cutout portions 41 are formed, even if the load of the above-mentioned rotation work for bending and deforming the projecting piece portion 40 from the connection portion of the second connecting member 22 with the connecting portion 36 is small. , The operator can more reliably bend and deform the projecting piece portion 40.

Further, in the present embodiment, the central shaft 24, which is a constituent member of the first building material connecting tool 20A, rotates the first connecting member 21 and the second connecting member 22 of the first building material connecting tool 20A. Since it is an insertion member that is commonly inserted into the first connecting member 21 and the second connecting member 22 in order to make it flexible, the first connecting member 21 and the second connecting member 22 are rotated. Compared with the case where the movable central axis is individually provided for each of the first connecting member 21 and the second connecting member 22, the number of members constituting the first building material connecting tool 20A can be reduced. As a result, the structure of the first building material connector 20A can be simplified and the manufacturing cost can be reduced.

In FIG. 16, as described above, between the ends 26A of the two connecting portions 26 and 35 of the first and second connecting members 21 and 22 of the first building material connecting tool 20A on the auxiliary member 8 side and at the ends. A state in which the auxiliary member 8 is inserted between the portions 35A is shown.

Further, as shown in FIG. 3, the operator may use the two second building material connecting tools 20B arranged at the lowermost portions of the left and right side frame members 2A and 2B of the door frame 2 with respect to each of the two connecting tools 20B for the second building material. As described above, by the work using the operation tool 60, the first connecting member 21 which is one connecting member of the second building material connecting tool 20B is rotated around the central shaft 24, and the first connecting member 21 is rotated. The inclination angle of the connecting member 21 with respect to the left-right direction M is set to be the same as or substantially the same as the inclination angle θ1 of the first connecting member 21 of the first building material connecting member 20A, and the two of the first connecting members 21. The auxiliary member 8 is inserted between the ends 26A on the auxiliary member 8 side of the connecting portion 26.

When the above work is performed, as can be seen from FIG. 16, both side portions of the first and second building material connecting tools 20A and 20B in the axial direction of the central shaft 24 and the bearing member 23 supporting the central shaft 24 are supported. Since a gap in the axial direction of the central shaft 24 is provided between the two extension portions 23B described above, the door frame 2 can move in the axial direction of the central shaft 24 by the gap. It has become. Therefore, the operator guides the door frame 2 to the central shaft 24 with respect to the connecting tools 20A and 20B for the first and second building materials and moves the door frame 2 in the thickness direction of the door frame 2. Can be arranged at a predetermined position in the thickness direction of the door frame 2 with respect to the auxiliary member 8 which is a building material on the wall 4 side.

As described above, between the ends 26A of the two connecting portions 26 and 35 on the auxiliary member 8 side and the end portion 35A of the first and second connecting members 21 and 22 of the first building material connecting tool 20A. When performing the work of inserting the auxiliary member 8 between each other and between the ends 26A on the auxiliary member 8 side of the two connecting portions 26 in the first connecting member 21 of the second building material connecting tool 20B. In addition, the auxiliary member 8 is not exactly linear in the length direction of the auxiliary member 8, and is orthogonal to the length direction of the auxiliary member 8 in the width direction of the auxiliary member 8 (thickness direction of the door frame 2). ), While absorbing this deformation by moving the first and second building material connecting tools 20A and 20B in the axial direction of the central axis 24, the above-mentioned insertion work of the auxiliary member 8 is performed. Can be carried out.

Then, after this, the operator attaches the ends of the first connecting member 21 on the auxiliary member 8 side of the first building material connecting tool 20A to the two connecting tools 25 shown in FIGS. 4 and 14. , By inserting it into the second hole 29 of FIG. 7 provided in the connecting portion 26 of the first connecting member 21 and screwing it into the auxiliary member 8, it is coupled to the auxiliary member 8 as shown in FIGS. 17 and 18. do. Further, the ends of the second connecting member 22 on the side of the auxiliary member 8 are also provided with the two coupling members 34 shown in FIGS. 4 and 14 at the connecting portion 35 of the second connecting member 22. By inserting it into the second hole 38 of FIG. 9 and screwing it into the auxiliary member 8, it is coupled to the auxiliary member 8 as shown in FIGS. 17 and 18.

Since the couplers 25 and 34 are drill screws, the work of joining the ends of the first and second connecting members 21 and 22 on the auxiliary member 8 side by the couplers 25 and 34 to the auxiliary member 8 is performed by the coupler. 25 and 34 are carried out by drilling a threaded hole in the auxiliary member 8. Therefore, the first and second connecting members 21 and 22 are not provided with the second holes 29 and 38, and the connecting tools 25 and 34 assist the ends of the first and second connecting members 21 and 22 on the auxiliary member 8 side. Even if the work of connecting to the member 8 is carried out by having the couplers 25 and 34 perform thread cutting holes on the ends of the first and second connecting members 21 and 22 on the auxiliary member 8 side and the auxiliary member 8. good.

Further, the operator also assists the two connecting portions 26 provided in the first connecting member 21 with respect to the first connecting member 21 which is one connecting member of the connecting tool 20B for the second building material. The end portion 26A on the member 8 side is coupled to the auxiliary member 8 by a coupling tool 25 similar to the two coupling tools 25 shown in FIGS. 4 and 14.

Since the connecting tool 25 used for the second building material connecting tool 20B is also a drill screw, the work of joining the end portion of the first connecting member 21 on the auxiliary member 8 side by the connecting tool 25 to the auxiliary member 8 is performed by the connecting tool 25. 25 is carried out by drilling a threaded hole in the auxiliary member 8. Therefore, also for the second building material connecting tool 20B, the first connecting member 21 is not provided with the second hole 29 into which the connecting tool 25 is inserted, and the connecting tool 25 is used to end the first connecting member 21 on the auxiliary member 8 side. The work of connecting the portions to the auxiliary member 8 may be carried out by having the coupling tool 25 perform thread cutting holes on the end portion of the first connecting member 21 on the auxiliary member 8 side and the auxiliary member 8.

The reason why the second building material connector 20B uses only the first connecting member 21 and does not use the second connecting member 22 is arranged below the first connecting member 21. By omitting the second connecting member 22, the connecting tool 20B for the second building material is placed at the lowermost portion of the left and right side frame members 2A and 2B, for example, the lower frame of the door frame 2 shown in FIG. This is to eliminate interference with the member 2D so that the members can be arranged effectively.

When the joining work by the connecting tools 25 and 34 described above is performed, the door frame 2 is attached to each auxiliary member 8, and in the plurality of first building material connecting tools 20A, the door frame 2 is connected to the two connecting portions 26 of the first connecting member 21. , Through the two connecting portions 35 of the second connecting member 22, and in the two second building material connecting tools 20B, via the two connecting portions 35 of the first connecting member 21, respectively. It means that they are connected. Then, in this connecting work, the first connecting member 21 and the second connecting member 22 are connected to the first building material connecting tool 20A inserted at the interval between the side frame members 2A and 2B and the auxiliary member 8. The tilt angles θ1 and θ2 with respect to the left-right direction M, which is the direction of the distance between the side frame members 2A and 2B, and the auxiliary member 8 are set to the same or substantially the same magnitude in opposite directions. Therefore, the door frame 2 is connected to the auxiliary member 8 in an immovable state in the vertical direction. Further, in the above-mentioned connecting work, for the first building material connecting tool 20A inserted at the interval between the upper frame member 2C and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are connected to the upper frame. Since the tilt angle with respect to the vertical direction, which is the direction of the distance between the member 2C and the reinforcing member 7, is set to be opposite to each other, the door frame 2 is left and right with respect to the auxiliary member 8. It is also connected in the direction of immobility.

The inclination angles θ1 and θ2 of the first connecting member 21 and the second connecting member 22 of the first building material connecting tool 20A and the inclination angle θ1 of the first connecting member 21 of the second building material connecting member 20B are set. It depends on the size of the distance between the door frame 2 and the auxiliary member 4. Therefore, before connecting the first and second building material connecting tools 20A and 20B to the auxiliary member 8 by the connecting tools 25 and 34, as shown in FIG. 3, the door frame 2 is attached to the door frame 2. It is arranged at an appropriate position in the left-right direction with respect to the two auxiliary members 8 arranged on both the left and right sides of the door frame 2, and also at an appropriate position in the vertical direction with respect to the auxiliary member 8 arranged above the door frame 2. By connecting the first and second building material couplers 20A and 20B to the auxiliary member 8 with the couplers 25 and 34, the placement position of the door frame 2 is appropriate for each auxiliary member 8. Can be the position of.

Therefore, among the side frame members 2A and 2B on both the left and right sides of the door frame 2, the size of the distance between the left side frame member 2A and the side frame member 2A and the auxiliary member 8 facing in the left-right direction is large. If the size of the distance between the right side frame member 2B and the side frame member 2B and the auxiliary member 8 facing each other in the left-right direction is different, they are arranged in the left side frame member 2A. The size of the inclination angles θ1 and θ2 for the first and second building material connecting tools 20A and 20B, and the inclination of the first and second building material connecting tools 20A and 20B arranged on the right side frame member 2B. The magnitudes of the angles θ1 and θ2 are different.

Further, as shown in FIGS. 17 and 18, the ends of the first connecting member 21 on the side of the auxiliary member 8 in the connecting tool 20A for the first building material are shown in FIGS. 4 and 14. When the two coupling members 25 are connected to the auxiliary member 8 by inserting them into the second hole 29 of FIG. 7 provided in each connecting portion 26 of the first connecting member 21, as described in FIG. In addition, the load W from the coupling tool 25 acts on the end portion 26A on the auxiliary member 8 side of each connecting portion 26. Therefore, the twist angle α existing at the end 26A on the auxiliary member 8 side is reduced or disappears due to the load W, and at the end opposite to the end 26A on the auxiliary member 8 side. A twist angle β is generated at the end portion 26B on the side of a certain door frame 2 as described above.

FIG. 19 is an enlarged cross-sectional view of the end portion 26B showing that such a twist angle β occurs at the end portion 26B of each connecting portion 26 of the first connecting member 21 on the door frame 2 side. As shown in FIG. 19, when a twist angle β occurs at the end 26B of the connecting portion 26 of the first connecting member 21 on the door frame 2 side, the twist angle β becomes the axial direction N of the central axis 24. Since the angle is inclined with respect to the central shaft 24, the first hole 28, which is an insertion portion provided at the end portion 26B on the door frame 2 side in order to insert the central shaft 24, also has an axial direction N of the central shaft 24. Will be tilted against. Therefore, the corner portion 28A of the first hole 28 is locked to the surface of the central shaft 24, in other words, the central shaft 24 is a locked member to which the corner portion 28A of the hole 28 is locked. By locking the hole 28 to the locked member, the first building material connector 20A, of which the first connecting member 21 is a constituent member, is a door frame 2 having an axial direction N of the central shaft 24. It becomes immobile in the thickness direction. Therefore, as described above, the door frame 2 arranged at a predetermined position in the thickness direction of the door frame 2 with respect to the auxiliary member 8 which is the building material on the wall 4 side is attached to the auxiliary member 8. The door frame 2 is connected in an immovable state in the thickness direction.

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

Further, in the present embodiment, in the second building material connecting tool 20B, the first connecting member 21 which is a component of the first building material connecting tool 20A is a side frame member 2A, 2B of the door frame 2 and the wall 4. The structure is used as a connecting member for connecting the auxiliary member 8, and the central shaft 24, which is a male screw rod, is also inserted through the first connecting member 21, so that it is used for the second building material. By connecting the first connecting member 21 of the connecting tool 20B to the auxiliary member 8 by the connecting tool 25, the door frame 2 is immovable to the auxiliary member 8 which is the building material on the skeleton side in the thickness direction of the door frame 2. It will be connected in a state.

Further, in the present embodiment, as described above, the load W of FIG. 8 by the coupling tool 25 of FIG. 4 acts on the end portion 26A on the side of each auxiliary member 8 of the two connecting portions 26 of the first connecting member 21. At that time, as described with reference to FIG. 8, the connecting portion 27 provided on the first connecting member 21 is in the direction of projecting to the outside of the first connecting member 21 in the thickness direction of the connecting portion 27. Along with the deformation such as bending to, a twist angle β is generated at the end portion 26B on the door frame 2 side of each of the first connecting members 21. In the present embodiment, since the bridging portion 27 is provided with an elongated hole 31 which is a strength reducing portion for reducing the strength of the bridging portion 27, the bridging portion 27 is curved due to the load W. Such deformations will occur more reliably, and as a result, the twist angle β of the end portion 26B on the door frame 2 side will also occur more reliably.

In the embodiment described above, the ends 26A and 35A on the auxiliary member 8 side of the two connecting portions 26 and 35 of the first and second connecting members 21 and 22 of the first building material connecting tool 20A are used as the auxiliary member 8. As shown in FIGS. 17 and 18, the coupling tools 25 and 34, which are two each for coupling, are arranged on opposite sides of the central axis 24 in the axial direction N, and these are arranged. In order to connect the ends 26A and 35A on the auxiliary member 8 side to the auxiliary member 8, the directions were opposite to each other in the axial direction N of the central axis 24.

It is a coupling tool for pulling the connecting portion 26D to the side of the connecting portion 26E arranged on the same side. Further, in order to connect the end portion 35A on the auxiliary member 8 side of the two connecting portions 35 of the second connecting member 22 to the auxiliary member 8, the above-mentioned one coupling tool 34 and another coupling tool 34 are used. 51 is used, and these couplers 34 and 51 are also arranged on the same side of the central axis 24 in the axial direction N, and have the same orientation in the axial direction N, and these couplers 34 are also used. Of the two connecting portions 35, the coupling member 51 is arranged on the side opposite to the same side on which the connecting members 34 and 51 are arranged in the axial direction N of the central axis 24. It is a coupling tool for pulling the portion 35D toward the side of the connecting portion 35E arranged on the same side.

The ends 26A and 35A on the opposite side of the side are strongly pressed by the auxiliary member 8. As a result, these ends 26A and 35A are in the same state as when they are connected to the auxiliary member 8.

According to this embodiment, the ends 26A and 35A on the auxiliary member 8 side of the two connecting portions 26 and 35 of the first and second connecting members 21 and 22 of the first building material connecting tool 20A are used as the auxiliary member 8. Since all the fittings 25, 34, 50, 51 for joining can be arranged on the same side of the central axis 24 in the axial direction N, these fittings 25, 34, 50, 51 can be rotated by a tool. The work for moving and advancing can also be performed by a worker who is on the same side in the axial direction N of the central axis 24, and therefore, the workability of this work is improved, and the work is facilitated and shortened. Can be achieved.

In addition, in the embodiment of FIGS. 20 and 21, in order to connect the end portion 26A on the auxiliary member 8 side of the two connecting portions 26 of the first connecting member 21 of the connecting tool 20B for the second building material to the auxiliary member 8. , The same binders as the couplers 25 and 50 can be used.

The side to be installed can be arbitrarily selected according to the condition of each installation site of the hinged door device.

Next, the operation tool 60 according to the embodiment of the present invention shown in FIGS. 22 to 25 will be described. 22 to 25 are a perspective view, a side view, a plan view, and a front view of the operation tool 60. The operation tool 60 is a plate-shaped main body 61 formed by punching and bending a metal thick plate, to which a gripping member 62 made of wood or synthetic resin is attached, and the main body 61 is a gripping member. 62 has a base portion 61A bonded by adhesive or a binder such as a screw, and the portion of the base portion 61A to which the gripping member 62 is attached is for the operator to grip and operate the operation tool 60. It is the operation unit 60A of. An extension portion 61B having a width dimension larger than that of the base portion 61A extends from a portion of the base portion 61A protruding from the grip member 62, and the extension portion 61B provided on the main body 61 extends. As can be seen from FIG. 23, the base portion 61A is bent and extended in the thickness direction of the main body 61 by the first bent portion 63. As shown in FIG. 22, the extension portion 61B includes a base portion 61C on the base portion 61A side and a bifurcated portion 61D on the side opposite to the base portion 61A side, and has the same width dimension. A second bent portion 64 is provided between the base portion 61C and the bifurcated portion 61D, whose bending direction is opposite to that of the first bent portion 63 in the thickness direction of the main body 61.

Further, the bifurcated portion 61D, which is a part of the main body 61 and is also a part of the extending portion 61B, is divided by the trunk portion 61E on the base portion 61C side and the notch portion 61F, and is connected by the trunk portion 61E. Each branch 61G, which is composed of two branches 61G and extends in parallel or substantially parallel to the trunk 61E, has a base portion 61H on the trunk 61E side and a third branch portion 61H with respect to the base portion 61H. It is composed of a tip portion 61I bent by the bent portion 65, and the bending direction of the third bent portion 65 is, as shown in FIG. 23, of the first bent portion 63 in the thickness direction of the main body 61. It is in the same direction as the bending direction. Therefore, the base portion 61C of the extending portion 61B and the tip portion 61I of the branch portion 61G are parallel to each other or substantially parallel to each other.

Further, as shown in FIG. 23, a plate-shaped cushioning member 66 formed of rubber, a porous elastic material, a soft synthetic resin, or the like is adhered to the lower surface of the base portion 61C of the extending portion 61B. The cushioning member 66 has the same area as the base 61C or substantially the same area as the base 61C, as shown in FIG. 22.

26 to 30 show that the first connecting member 21 and the second connecting member 22 are oriented as described above by bending the first building material connecting tool 20A in a dogleg shape with the operating tool 60. The work of orienting the wall 4 toward the auxiliary member 8 side is shown. When this work is started, as shown in FIG. 26, the first connecting member 21 and the second connecting member 22, which are the two connecting members of the first building material connecting tool 20A, have a central axis. Arranged on opposite sides to the 24, these first and second connecting members 21 and 22 are parallel or substantially parallel to each other, and therefore these first and second connecting members 21, The direction of 22 is a direction orthogonal to the spacing direction between the door frame 2 and the auxiliary member 8 of the wall 4 and the thickness direction of the door frame 2. With respect to the first building material connecting tool 20A having such a shape, the operator attaches the tip portion 61I, which is the most tip side of the main body 61 of the operation tool 60, to the first connecting member 21 and the second. It is inserted behind the connecting member 22, and this insertion work is performed while inserting the central shaft 24 and the bearing member 23 supporting the central shaft 24 into the notch 61F provided in the main body 61. ..

After performing the above-mentioned insertion work, the operator can move the operation unit 60A of the operation tool 60 toward the door frame 2 side to bring the operation tool 60 into the posture shown in FIG. 27. FIG. 28 is a plan view of FIG. 27. In the operation tool 60 at this time shown in FIGS. 27 and 28, the two tip portions 61I provided on the main body 61 are parallel to or substantially parallel to the first and second connecting members 21 and 22, respectively, and the main body Of the extension portions 61B of 61, the base portion 61C to which the cushioning member 66 is attached is in a state of being parallel to or substantially parallel to the door frame 2, and the base portion 61C is connected to the door frame 2 via the cushioning member 66. Are in contact with.

Next, when the operator applies an operating force in the direction of the arrow A shown in FIGS. 27 and 28 to the operating portion 60A of the operating tool 60, the operating tool 60 comes into contact with the door frame 2 via the cushioning member 66. Since it rotates around the base portion 61C, a pressing force acts on each tip portion 61I in a direction opposite to the operating force. At this time, each of the tip portions 61I has the first connecting member 21 and the second connecting member 22 from the central axis 24 to the door frame 2 as can be seen from FIG. 29 and FIG. 30 which is a plan view of FIG. 29. The direction orthogonal to the spacing direction between the wall 4 and the auxiliary member 8 of the wall 4 and the thickness direction of the door frame 2 (for the first building material connector 20A attached to the side frame members 2A and 2B of the door frame 2). Since the first connecting member 20A attached to the upper frame member 2C of the door frame 2 is pressed in the vertical direction (in the left-right direction) by the above-mentioned pressing force, the first connecting member 21 and the first connecting member 21 and the first connecting member 20A are pressed. The two connecting members 22 rotate about the central axis 24 while extinguishing the parallel function of the parallel means 45 described with reference to FIGS. 12 and 15, so that the angle about the central axis 24 becomes smaller and the first The connecting tool 20A for building materials is bent into a dogleg shape.

When the first building material connector 20A is bent in a dogleg shape in this way, as described above, between the ends 26A of the two connecting portions 26 of the first connecting member 21 on the auxiliary member 8 side. The auxiliary member 8 is inserted into the second connecting member 22, and the auxiliary member 8 is also inserted between the ends 35A on the auxiliary member 8 side of the two connecting portions 35 of the second connecting member 22. Therefore, the first connecting member 21 is connected to the auxiliary member 8 by the two connecting tools 25 shown in FIG. 4 and the like, and the second connecting member 21 is connected to the auxiliary member 8 by the two connecting tools 25 shown in FIG. 4 and the like. In the case of connecting with the connecting tool 34, the operating force is continuously applied to the operating portion 60A of the operating tool 60 even after the connecting tool 20A for the first building material is bent in a dogleg shape. As shown in 31, the first connecting member 21 and the second connecting member 22 are continuously pressed toward the auxiliary member 8 by the respective tip portions 61I of the operation tool 60, whereby these first connecting members are pressed. The tips of the 21 and the second connecting member 22 are brought into contact with the reinforcing member 7 to which the auxiliary member 8 is attached. Then, while maintaining this state, the operator uses the connecting tools 25 and 34, which are drill screws, to end the connecting portions 26 and 35 of the first and second connecting members 21 and 22 on the auxiliary member 8 side. Work is performed to connect 26A and 35A to the auxiliary member 8.

The ends 26A and 35A on the auxiliary member 8 side of the connecting portions 26 and 35 of the first and second connecting members 21 and 22 are coupled to the auxiliary member 8 by the coupling tools 25 and 34 which are drill screws in this way. The first connecting member 21 and the second connecting member 22 are orthogonal to the distance direction between the central axis 24 and the door frame 2 and the auxiliary member 8 and the thickness direction of the door frame 2. When the pressing force from the tip portion 61I of the operating tool 60 continues to be pressed at a position separated in the direction, the fittings 25 and 34 are provided with the second holes 29, provided in the first and second connecting members 21 and 22. Even if the auxiliary member 8 is inserted into the 38 to drill a threaded hole, the first and second connecting members 21 and 22 are provided with the second holes 29 and 38 as described above. However, even if the fittings 25 and 34 are for drilling holes in the first and second connecting members 21 and 22 and the auxiliary member 8, the first and second connecting members 25 and 34 are drilled. Since the first and second connecting members 21 and 22 are in contact with the reinforcing member 7, the work of connecting the second connecting members 21 and 22 and the auxiliary member 8 is performed on the first and second connecting members 21. , 22 can be performed by preventing slight movements such as swinging around the central shaft 24, whereby this coupling work can be effectively performed.

When the first connecting member 21 and the second connecting member 22 are pressed toward the auxiliary member 8 by the respective tip portions 61I of the operation tool 60, the first connecting member 21 and the second connecting member 22 come into contact with each other. The member is not the reinforcing member 7, but the auxiliary member 8, and in order to make this contact, the first connecting member 21 and the above-mentioned bridging portions 27, 36 of the second connecting member 22 are brought into contact with the auxiliary member 8. You may let me.

Further, from the time when the operation tool 60 bends the first building material connecting tool 20A in a dogleg shape, the connecting tools 25 and 34 are used to connect the first and second connecting members 21 and 22 to the connecting portions 26 and 35. It is a tool that continuously presses the first and second connecting members 21 and 22 by the two tip portions 61I until the work of connecting the ends 26A and 35A on the auxiliary member 8 side to the auxiliary member 8 is completed. Therefore, these operations can be performed as continuous and consistent operations using the same operation tool 60, and therefore, these operations can be performed with improved workability in a short time. can.

Further, the first building material connecting tool 20A is a single shaft common to the first and second connecting members 21 and 22, which are the two connecting members of the first building material connecting tool 20A. Since it has a central shaft 24, the number of central shafts 24 to be inserted together with the bearing member 23 in the notch 61F of the operation tool 60 when performing the above-mentioned work is sufficient, and therefore only one is required. The size of the notch 61F provided in the operation tool 60 can be reduced.

Further, as can be seen from the above description, in the operation tool 60 according to the present embodiment, as shown in FIG. 28 and the like, the first and first operation tools 60 are located on one end side in the length direction of the operation tool 60. Since two tip portions 61I for pressing the two connecting members 21 and 22 are provided, these tip portions 61I are pressing portions provided on one end side in the length direction of the operation tool 60. It is 60C, and on the other end side of the operating tool 60 in the length direction, the above-mentioned operating portion 60A operated to generate a pressing force in the pressing portion 60C is provided. Then, by contacting the door frame 2 via the cushioning member 66 in the middle portion of the operating tool 60 in the length direction, the pressing force of the pressing portion 60C is applied to the direction of the operating force of the operating portion 60A. A base 61C which is a fulcrum portion 60B for reversing the direction in the opposite direction is provided. Therefore, by making the distance between the operation unit 60A and the fulcrum unit 60B larger than the distance between the fulcrum unit 60B and the pressing unit 60C, the pressing unit 60C is more than the operating force of the operating unit 60A according to the principle of the lever. From this, the parallel function of the parallel means 45 described with reference to FIGS. 12 and 15 can be more reliably extinguished, and the first building material connector 20A can be shaped like a dogleg. Can be bent to.

Further, among the main body 61 of the operation tool 60, the base portion 61C which is the fulcrum portion 60B is provided with a cushioning member 66 for preventing the base portion 61C from coming into direct contact with the door frame 2. Even if a large operating force is applied to the operation unit 60A, the door frame 2 can be effectively prevented from being damaged by the cushioning member 66.

Further, the main body 61 of the operation tool 60 according to the present embodiment is provided with a bifurcated portion 61D formed by the notch portion 61F, and the number of the pressing portions 60C by the tip portion 61I is the number of the notch portions 61F. Since there are two branches, one for each of the two branches 61G provided for the bifurcated portion 61D, the first and two connecting members are provided for the first building material connector 20A. In the operation tool 60 according to the present embodiment, the second connecting members 21 and 22 can be pressed at the same time by the two pressing portions 60C, whereby the connecting tool 20A for the first building material is shaped like a dogleg. It can be bent instantly.

The above description has been given to the first building material connecting tool 20A in which two connecting members are provided as the first and second connecting members 21 and 22, but only the first connecting member 21 is connected by one. The operation tool 60 according to the present embodiment is also used for the second building material connector 20B provided as a member.

That is, when the operation tool 60 according to the present embodiment is used for the second building material connecting tool 20B, the central shaft 24 of the second building material connecting tool 20B is used as in the case of the first building material connecting tool 20A. While inserting the bearing member 23 supporting the central shaft 24 into the notch 61F of the operation tool 60, one of the two tip portions 61I is connected to the first connecting member. Insert behind 21. After that, by applying the same operating force as that of the first building material connecting tool 20A to the operating portion 60A, the first connecting member 21 is pressed by the pressing force from the tip portion 61I which is the pressing portion 60C. It is rotated around the central axis 24 so that the direction is orthogonal to the direction of spacing between the door frame 2 and the auxiliary member 8 of the wall 4 and the thickness direction of the door frame 2. The direction of the first connecting member 21 was set to be inclined toward the auxiliary member 8 side of the wall 4, and the two connecting portions 26 of the first connecting member 21 were assisted between the ends 26A on the auxiliary member 8 side. The member 8 is inserted.
