In the work of arranging the opening frames such as door frames on the wall, the opening frames that are the building materials for the hinged doors are arranged at intervals on the skeleton side building material provided on the wall side, and these skeleton sides are arranged. This is done by connecting the building material and the opening frame with a connecting member.

An object of the present invention is a connecting member for building materials, a connecting tool thereof, which makes it possible to easily and quickly perform work for connecting two building materials arranged at intervals by improving workability. It is here to provide the connecting structure and the connecting method.

The building material connecting member according to the present invention is a building material connecting member for connecting two building materials arranged at intervals, and both ends thereof are one of the two building materials. Has a locking member arranged so that the thickness direction of the one building material orthogonal to the direction of the spacing is the axial direction, and a connecting portion reaching the other building material of the two building materials. Of the two ends of the connecting portion, the other end on the building material side is formed with a twist angle that is an inclination angle of the locked member with respect to the axial direction, and is formed on the other building material side. When the end portion is connected to the other building material with a binder and the twist angle of the end portion is reduced or extinguished, the end portion on the building material side of the both end portions of the connecting portion is described. A twist angle with respect to the axial direction can be generated, and when this twist angle is generated, the end portion on the one building material side is locked to the locked member to connect the two building materials. Is to be.

As described above, according to the building material connecting member according to the present invention, of the both ends of the connecting portion, the other end on the building material side is formed with a twist angle which is an inclination angle with respect to the axial direction of the locking member. The other end on the building material side is joined to the other building material with a binder, and the twist angle of this end is reduced or eliminated, so that one of the both ends of the connecting portion is on the building material side. A twist angle with respect to the axial direction is generated at the end portion of the building material, and due to the generation of the twist angle, the end portion on the one building material side is locked to the locked member arranged on the other building material. Since the building materials of the above are connected, the two building materials are locked by performing the work of joining the other end of the connecting portion on the building material side to the other building material with a binder. This means that the work of immobilizing and connecting the two building materials in the axial direction was naturally carried out, and therefore, the work of connecting the two building materials arranged at intervals is easy and short with improved workability. You can do it in time.

In the above-mentioned connecting member of the building material according to the present invention, locking the end of the connecting portion on the building material side to the locked member is, for example, locked to the end. This can be achieved by providing an insertion portion for inserting the member.

This insertion portion may be a hole or a notch such as a recess.

Further, the number of the connecting portions provided in the connecting member of the building material according to the present invention may be one or two provided in the axial direction of the locked member. Further, when the number of connecting portions is two provided in the axial direction of the locked member, these connecting portions are connected by a bridging portion having a width dimension in the axial direction of the locked member. You may.

In this case, the number of connecting portions is two provided in the axial direction of the locked member, and these connecting portions are connected by a bridging portion having a width dimension in the axial direction of the locked member. May have the same twisting angle direction with respect to the other end on the building material side of both ends of the two connecting portions, or may be opposite to each other.

Further, when two connecting portions are connected by a connecting portion having a width dimension in the axial direction of the locked member, the connecting portion has a strength reducing portion that reduces the strength of the connecting portion. May be provided.

According to this, when each of the ends of the two connecting portions on the other building material side is connected to the other building material with a binder, the bridging portion is deformed such as curved due to the decrease or disappearance of the torsion angle. As a result, a twist angle is generated at each of the ends of the two connecting portions on the building material side so that these ends can be locked to the locked member. By providing a strength-reducing portion that reduces the strength of the bridging portion, deformation such as bending is likely to occur in the bridging portion, and each of the ends on the building material side is used as a locked member. It can be locked more reliably.

The strength-reducing portion may be a hole such as a long hole or a round hole, a notched portion such as a recess, or a thin-walled portion.

Further, in the building material connecting member according to the present invention, of the two end portions of each of the two connecting portions connected by the bridging portion, the other end on the building material side is to be connected to the other building material. Each of the fittings is arranged on opposite sides in the axial direction of the locked member, and in the axial direction of the locked member in order to bond the end portion of the other building material side to the other building material. They may be oriented in opposite directions, or these binders are arranged on the same side in the axial direction of the locked member, and the end portion of the other building material side is the other building material. It is assumed that the locked members are oriented in the same axial direction in order to be coupled to the above, and one of these couplers is to be the locked member of the two connecting portions. The connecting portion arranged on the side opposite to the same side in the axial direction of the locked member may be used as a coupling tool for pulling the connecting portion arranged on the same side in the axial direction of the locked member. ..

Assuming that the connecting tool is the latter, the work for joining the end portion of the two connecting portions on the building material side of the other connecting portion to the other building material is performed. Since it can be performed from the same side in the axial direction of the locked member, workability can be further improved, and the work of connecting the two building materials can be performed, for example, at the inside corner of the building. You will be able to do it.

Further, in the building material connecting member according to the present invention, by connecting the other building material side end portion of the above-mentioned connecting portion to the other building material with a binder, the one end portion of the connecting portion on the building material side is joined. In order to generate a twisting angle and ensure that the end portion is more reliably locked to the locked member, it is preferable that the locked member has irregularities on its surface. According to this, the end portion of the connecting portion on the building material side is more reliably locked to the locked member due to the unevenness on the surface of the locked member.

In order to make the locked member a member having irregularities on the surface in this way, the locked member may be, for example, a male screw rod having male threads formed on the surface, or the entire circumference direction. A rod-shaped member in which ridges and grooves formed on the circumference are alternately and continuously arranged in the axial direction may be used.

The building material connecting tool according to the present invention is a building material connecting tool for connecting two building materials arranged at intervals, and each is a member for connecting the two building materials. The first connecting member is composed of a first connecting member and a second connecting member, and both ends of the first connecting member are orthogonal to one of the two building materials in the direction of the interval. It has a locking member that is arranged with the thickness direction of the building material in the axial direction and a connecting portion that reaches the other building material of the two building materials, and among the both ends of the connecting portion. , The other end on the building material side is formed with a twist angle that is an inclination angle of the locked member with respect to the axial direction, and the end on the other building material side is a coupling tool to the other building material. By reducing or extinguishing the twisting angle of this end portion, it becomes possible to generate a twisting angle with respect to the axial direction at one of the both ends of the connecting portion on the building material side. When this twisting angle is generated, the end portion on the one building material side is locked to the locked member to connect the two building materials, and the first connecting member is tilted with respect to the direction of the interval. The two building materials are connected at an angle, and the inclination angle of the second connecting member with respect to the direction of the interval is opposite to the inclination angle of the first connecting member. It is characterized in that the two building materials are connected to each other.

According to this building material connecting tool, of both ends of the connecting portion of the first connecting member, the other end on the building material side is formed with a twist angle which is an inclination angle of the locked member with respect to the axial direction. The other end on the building material side is joined to the other building material with a binder, and the twist angle of this end is reduced or eliminated, so that one of the both ends of the connecting portion is on the building material side. A twist angle with respect to the axial direction is generated at the end portion of the building material, and due to the generation of the twist angle, the end portion on the one building material side is locked to the locked member arranged on the other building material. Since the building materials of the above building materials are connected, the connecting tool of the building material also performs the work of connecting the ends of the connecting portion of the first connecting member on the other building material side to the other building material with the connecting tool. As a result, the work of connecting the two building materials by immobilizing them in the axial direction of the locked member can be carried out naturally, and therefore, the work of connecting the two building materials arranged at intervals is performed. Can be done easily and in a short time by improving workability.

Further, according to the connecting tool of the building material, the first connecting member connects the two building materials at an inclination angle with respect to the direction of the distance between the two building materials, and the second connecting member has 2 Since the inclination angle with respect to the direction of the interval between the building materials is the inclination angle opposite to the inclination angle of the first connecting member to connect these building materials, the first connecting member and the second connecting member are connected. After connecting the two building materials with the members, these building materials can be immovably connected in the vertical direction or the like, which is a direction orthogonal to the direction of the distance between the two building materials.

In the connecting tool of the building material, an insertion member different from the locked member may be inserted through the end of the second connecting member on the building material side, but the locked member is inserted. , The member inserted as a common insertion member at the end on the building material side of the first connecting member and the second connecting member may be used.

According to this, by standardizing the insertion members, it is possible to simplify the structure and reduce the cost by reducing the number of members.

The structure is such that the two building materials are connected by a first connecting member and a second connecting member, and both ends of the first connecting member are in the direction of the distance from one of the two building materials. It has a locked member arranged so that the thickness direction of the one building material orthogonal to the above is the axial direction, and a connecting portion that reaches the other building material of the two building materials. Of the two ends of the above, the other end on the building material side is formed with a twist angle that is an inclination angle of the locked member with respect to the axial direction, and the other end on the building material side is this. When the twist angle of the end portion is reduced or disappears by being connected to the other building material by a binder, the twist angle with respect to the axial direction is attached to the end portion of the one end portion of the connecting portion on the building material side. Is possible, and when this twisting angle is generated, the end portion on the one building material side is locked to the locked member to connect the two building materials, and the first connecting member is The two building materials are connected at an inclination angle with respect to the direction of the interval, and the inclination angle of the second connecting member with respect to the direction of the interval is opposite to the inclination angle of the first connecting member. It is characterized in that the two building materials are connected at an inclination angle of.

It is formed with a twist angle that is an inclination angle, and the end on the other building material side is joined to the other building material with a binder, and the twist angle of this end decreases or disappears, so that the connecting portion A twist angle with respect to the axial direction is generated at one end of both ends on the building material side, and the generation of this twist angle causes the end on the one building material side to be arranged on the other building material. Since the two building materials are connected by being locked to the locking member, even in this building material connecting structure, of the both ends of the connecting portion of the first connecting member, the other end on the building material side is the other. By performing the work of joining the building materials with a binder, it is possible to naturally carry out the work of immobilizing the two building materials in the axial direction of the locked member and connecting them, and therefore, they are arranged at intervals. The work for connecting two building materials can be performed easily and in a short time with improved workability.

Further, according to the connecting structure of the building materials, the first connecting member connects the building materials at an inclination angle with respect to the direction of the distance between the two building materials, and the second connecting member is the two building materials. Since the inclination angle with respect to the direction of the interval is an inclination angle opposite to the inclination angle of the first connecting member and these building materials are connected, the first connecting member and the second connecting member form two building materials. After connecting the two building materials, these building materials can be immovably connected in the vertical direction or the like, which is a direction orthogonal to the direction of the distance between the two building materials.

After connecting the two building materials with the members, these building materials can be immovably connected in the vertical direction or the like, which is a direction orthogonal to the direction of the distance between the two building materials.

Further, according to this method of connecting building materials, when the first connecting member and the second connecting member are inserted between the two building materials in the first work step, the first connecting member and the second connecting member are connected by 2. In order to make the building materials parallel or substantially parallel to each other while arranging them in a direction orthogonal to the direction of the spacing between the building materials and the thickness direction of one of the building materials, the first connecting member is used in the first working process.

An intermediate portion 26C is provided between the end portion 26A on the auxiliary member 8 side and the end portion 26B on the door frame 2 side to gradually eliminate the twist angle α. The end portion 26B on the door frame 2 side is provided with a large-diameter first hole 28 as an insertion portion for inserting the central shaft 24, and the end portion 26A on the auxiliary member 8 side is shown in FIG. A second hole 29 having a small diameter for inserting the indicated coupling tool 25 is provided. Further, in the range of the end portion 26A on the auxiliary member 8 side in which the above-mentioned twist angle α exists in each connecting portion 26, the coupling tool 50, which is a tapping screw described later in FIGS. 19 and 20, A third hole 30 for inserting the 51 is also provided.

Further, the connecting portion 27 is provided with an elongated hole 31, and the elongated hole 31 which is elongated in the length direction of the connecting portion 26 is formed in the connecting portion 27 in order to reduce the strength of the connecting portion 27. It is a formed strength-reducing part.

As described above, the first connecting member 21 has a substantially U-shape as a whole formed by the two connecting portions 26 and the connecting portion 27 bridged over these connecting portions 26. 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 C 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 each auxiliary member 8 side, the twist angle α shown in FIG. 7 of the end portion 26A on the auxiliary member 8 side 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 protruding 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 that is an inward tilt angle of the first connecting member 21 is generated, and this twist angle β is a twist angle that is opposite to each other with respect to the end portion 26B on the door frame 2 side. Become.

As a result, in the whole of the 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.

9 shows a second connecting member 22, and FIGS. 9A and 9B are a side view and a rear view of the second connecting member 22. Similar to the first connecting member 21, the second connecting member 22, which is a punched and bent product of a metal plate, is also provided with two connecting portions 35 facing each other in the axial direction N of the central shaft 24. Since the bridging portion 36 is bridged between the end portions of the connecting portion 35 in the thickness direction of the entire second connecting member 22 on the side orthogonal to the axial direction N of the central axis 24. The two connecting portions 35 are connected by a bridging portion 36 having an axial direction N of the central shaft 24 as a width dimension. 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 frame of the wall 4.

Further, of the both end portions 35A and 35B in the length direction of the respective connecting portions 35, the end portion 35A on the auxiliary member 8 side is slightly inward of the second connecting member 22 with respect to the end portion 35B on the door frame 2 side. 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. The end 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. Further, each connecting portion 35 is also provided with a third hole 39 for inserting the coupling tools 50 and 51 which are tapping screws, as will be described later in FIGS. 19 and 20.

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 protrudes 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. ..

The projecting piece portion 40 formed on the second connecting member 22 in this way is bent in the thickness direction when a load is applied to the projecting piece portion 40 in the thickness direction of the entire second connecting member 22. This bending is possible, and two notches 41 are provided at the end 36B of the bridging portion 36 on both sides of the projecting piece 40, and these notches 41 are provided as the bridging portions. Since it is a strength reducing portion for reducing the strength of the base end portion of the projecting piece portion 40 in 27, the projecting piece portion 40 can be easily bent even if the load is small.

The first connecting member 20A including the first connecting member 21, the second connecting member 22, the bearing member 23, and the central shaft 24 described above is a front view of the first connecting member 20A. And, the structure shown in FIG. 11 showing the side view of the first connector 20A is assembled in the factory where the door frame 2 shown in FIG. 3 is manufactured. In this assembly, the central shaft 24 is commonly inserted into the first hole 28 provided in the connecting portion 26 of the first connecting member 21 and the first hole 37 provided in the connecting portion 35 of the second connecting member 22. It is inserted as a member, and the central shaft 24 is also inserted into a bearing member 23 having a hat shape, and both ends of the central shaft 24 are processed to be retaining portions 24A from the bearing member 23.

The central shaft 24 according to the present embodiment is a male screw rod in which a large number of irregularities due to threads and threads are alternately formed on the surface in the axial direction.

FIG. 12, which is a cross-sectional view taken along the line S12-S12 of FIG. 11, shows the first connecting tool 20A assembled by the first connecting member 21, the second connecting member 22, the bearing member 23, and the central shaft 24 as described above. A cross section is shown. In the first connecting tool 20A assembled at the factory, the projecting piece portion 40 formed on the second connecting member 22 is in contact with the back surface 27A of the bridging portion 27 provided on the first connecting member 21. .. Therefore, the first connecting member 21 and the second connecting member 22 in which the central shaft 24 is a common insertion member are connected by the central shaft 24 and are connected to the first connecting member 21. The second connecting member 22 is parallel or substantially parallel to each other in a direction orthogonal to the axial direction N of the central axis 24.

Therefore, the projecting piece portion 40 constitutes a parallel means 45 for arranging the first connecting member 21 and the second connecting member 22 in a direction orthogonal to the axial direction N of the central axis 24 to make them parallel or substantially parallel. It is supposed to be done. Further, when the first connector 20A is inserted into the gap between the door frame 2 shown in FIG. 3 and the auxiliary member 8 which is a building material on the wall side, as will be described later, the first connector 20A is parallel to the door frame 2. By the parallel function of the means 45, the first connecting member 21 and the second connecting member 22 are connected to each other in the direction of the distance between the door frame 2 and the auxiliary member 8 which are two building materials, and the door frame 2 and the auxiliary member. Of 8, the direction perpendicular to the thickness direction of the door frame 2 (which is also the thickness direction of the wall 4 shown in FIGS. 1 and 2) (arranged in the side frame members 2A and 2B of the door frame 2). The first connector 20A can be made parallel or substantially parallel while being lined up in the vertical direction and in the horizontal direction in the first connector 20A arranged on the upper frame member 2C of the door frame 2.

In the above first connector 20A, as can be seen from FIG. 4, the bearing member 23 is welded to the left and right side frame members 2A and 2B and the upper frame member 2C of the door frame 2 at the factory where the door frame 2 is manufactured. By being combined, it is attached to the door frame 2. Further, the second connecting member 20B shown in FIG. 3 includes a first connecting member 21, a bearing member 23, and a central shaft 24. Therefore, the second connecting member 20B is a first connecting member 20A to a second connecting member. It has the same structure as the one with 22 removed. Such a second connecting tool 20B is also attached to the door frame 2 at the factory by connecting the bearing members 23 to the left and right side frame members 2A and 2B of the door frame 2 by welding or the like.

The door frame 2 to which the first connecting tool 20A and the second connecting tool 20B are attached at the factory is carried to the work site where the hinged door device of FIG. 1 is installed, and after that, in FIG. 4 of the wall 4 of FIG. Before the indicated face member 6 is attached to the core member 5, the left and right side frame members 2A and 2B of the door frame 2 are connected to the core members 5A and 5B of FIG. 3 to form the wall 4 of FIG. The first connecting tool 20A and the second connecting tool 20B are inserted at a distance in the left-right direction between the auxiliary member 8 attached to the reinforcing member 7, and the upper frame member 2C of the door frame 2 and FIG. The first connecting tool 20A is inserted in the vertical space between the auxiliary member 8 attached to the reinforcing member 7 coupled to the core member 5C of the door frame 2 and the door frame 2 and the first and second. The connectors 20A and 20B are arranged inside the opening 4A of the wall 4 shown in FIGS. 1 and 2. The work of attaching the auxiliary member 8 to the reinforcing member 7 is the work of arranging the door frame 2 and the first and second connecting tools 20A and 20B inside the opening 4A of the wall 4 as described above. It is done just before.

In the present embodiment, when the door frame 2 and the first and second connecting tools 20A and 20B are arranged inside the opening 4A of the wall 4 as described above, the first connection of the first connecting tool 20A is performed. Even if the member 21 and the second connecting member 22 are rotatable about the central shaft 24, they are attached to the side frame members 2A and 2B of the door frame 2 and the reinforcing member 7 connected to the core members 5A and 5B. With respect to the first connecting member 20A inserted at a distance in the left-right direction between the auxiliary member 8 and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are separated by the parallel function of the parallel means 45 described above. It can be parallel or substantially parallel while being lined up in the horizontal direction, which is the distance between the side frame members 2A and 2B and the reinforcing member 7, and the vertical direction, which is the direction orthogonal to the thickness direction of the door frame 2. Further, regarding the first connecting tool 20A inserted at a vertical distance 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. Due to the parallel function of the parallel means 45, the first connecting member 21 and the second connecting member 22 are orthogonal to the vertical direction, which is the distance between the upper frame member 2C and the reinforcing member 7, and the thickness direction of the door frame 2. It is possible to make them parallel or substantially parallel while arranging them in the left-right direction, which is the direction of

Therefore, as described above, the first connecting member 21 and the second connecting member 22 of the first connecting tool 20A are rotatable about the central shaft 24, and the side frame members 2A and 2B and the reinforcing member 7 Even if the distance between the upper frame member 2C and the reinforcing member 7 in the vertical direction is small, the first connector 20A can be effectively inserted into these gaps, and during this insertion work, the first connector 20A can be effectively inserted. Since it is only necessary to carry out this insertion work with only the first connecting member 21 of the second connecting tool 20B standing upward with respect to the central axis 24 of the second connecting tool 20B, a small number of workers are required. Workability can be improved and the work can be completed easily and in a short time.

After inserting the plurality of first connecting members 20A into the lateral distance between the side frame members 2A and 2B and the reinforcing member 7 and the vertical spacing between the upper frame member 2C and the reinforcing member 7 as described above. , The operator attaches at least one of the first connecting member 21 and the second connecting member 22 in each of the first connecting members 20A to the other connecting member with the side frame member 2A centered on the central axis 24. , 2B side and upper frame member 2C side are rotated to the opposite side. This rotation work is performed on, for example, the second hole 29 and the third hole 30 shown in FIG. 7 of the first connecting member 21, and the second hole 38 and the third hole 39 shown in FIG. 9 of the second connecting member 22. It can be carried out by inserting a tool or the like.

FIG. 14 is a cross-sectional view taken along the line S14-S14 of FIG. 13 showing a side view of the first connector 20A after the rotation work is performed. As shown in FIG. 14, when the above-mentioned rotation work is performed, the second connecting member 22 is provided and is in contact with the back surface 27A of the connecting portion 27 of the first connecting member 21. The projecting piece portion 40 is bent from the connection portion of the second connecting member 22 with the connecting portion 36 due to the load due to the rotating work by the operator, whereby the parallel function of the parallel means 45 disappears. Therefore, among the plurality of first connecting members 20A, the first connecting member 20A inserted at the distance between the side frame members 2A and 2B and the reinforcing member 7 is the first connecting member 21 and the second connecting member 22. 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. 10, the lateral direction M, which is the direction of the distance between the side frame members 2A and 2B and the reinforcing member 7. By rotating the central axis 24 so that the inclination angles θ1 and θ2 with respect to the above are opposite to each other, the two connecting portions 26 and 35 in the first and second connecting members 21 and 22 are formed. 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 shown in FIGS. 7 and 9 (see FIG. 15). Further, regarding the first connecting member 20A inserted at the distance 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 each other, and the distance between the upper frame member 2C and the reinforcing member 7 is provided. The two connecting portions 26 in the first and second connecting members 21 and 22 are rotated around the central axis 24 so that the tilt angles with respect to the vertical direction, which is the direction of the above, are opposite to each other. , 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 connecting tools 20A, the first connecting member 21 relates to the direction of the distance between the side frame members 2A and 2B and the auxiliary member 8 and the direction of the distance between the upper frame member 2C and the auxiliary member 8. In addition to forming an inclination angle, the second connecting member 22 has an inclination angle with respect to the direction of the distance between the side frame members 2A and 2B and the auxiliary member 8 and the direction of the distance between the upper frame member 2C and the auxiliary member 8. , The inclination angle of the first connecting member is opposite to that of the first connecting member.

In these first connecting members 20A, as described above, the second connecting member 22 has 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 rotating work for bending 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 bend the projecting piece 40 more reliably.

Further, in the present embodiment, the central shaft 24, which is a constituent member of the first connecting tool 20A, makes the first connecting member 21 and the second connecting member 22 of the first connecting tool 20A rotatable. In addition, since the first connecting member 21 and the second connecting member 22 are inserted in common, the first connecting member 21 and the second connecting member 22 are rotatable. Compared with the case where the central axis is individually provided on the first connecting member 21 and the second connecting member 22, the number of members constituting the first connecting member 20A can be reduced, whereby the structure can be reduced. Simplification and reduction of manufacturing cost can be achieved.

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

After performing the above-mentioned work, the operator attaches the ends of the first connecting member 21 on the side of the auxiliary member 8 of the first connecting member 20A to the two connecting members shown in FIGS. 4 and 13. By inserting the 25 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, the auxiliary member 8 is screwed into the auxiliary member 8 as shown in FIGS. 16 and 17. Also, the ends of the second connecting member 22 on the side of the auxiliary member 8 also have the two coupling members 34 shown in FIGS. 4 and 13 attached to the connecting portion 35 of the second connecting member 22. By inserting it into the second hole 38 of FIG. 9 provided in the above and screwing it into the auxiliary member 8, it is coupled to the auxiliary member 8 as shown in FIGS. 16 and 17.

Further, as shown in FIG. 3, the operator can use the first of the two second connecting tools 20B arranged at the lowermost portions of the left and right side frame members 2A and 2B of the door frame 2. The connecting member 21 is rotated around the central axis 24, and the tilt angle of the first connecting member 21 with respect to the above-mentioned left-right direction M is defined as the tilt angle θ1 of the first connecting member 20A with respect to the first connecting member 21. In the same or substantially the same manner, the end portion of the first connecting member 21 on the auxiliary member 8 side is coupled to the auxiliary member 8 by the same coupling tool as the two coupling tools 25 shown in FIGS. 4 and 13. ..

The reason why these second connecting members 20B are based on the fact that the first connecting member 21 is used and the second connecting member 22 is not used is that they are arranged below the first connecting member 21. By omitting the second connecting member 22, the second connecting member 20B can be effectively arranged at the lowermost portion of the left and right side frame members 2A and 2B.

When the coupling work by the coupling 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 coupling members 20A, the door frame 2 is connected to the two connecting portions 26 of the first connecting member 21. The two connecting members 22 were connected to each other via the two connecting portions 35, and the two second connecting members 20B were connected to each other via the two connecting portions 35 of the first connecting member 21. become. Then, in this connecting work, for the first connecting tool 20A inserted at the distance between the side frame members 2A and 2B and the reinforcing member 7, the first connecting member 21 and the second connecting member 22 are connected to the side frame member 2A. , 2B and the reinforcing member 7 are oriented so that the tilt angles θ1 and θ2 with respect to the left-right direction M, which is the direction of the distance between the two B and the reinforcing member 7, are opposite to each other. Therefore, they are connected in an immovable state in the vertical direction. Further, in the above-mentioned connecting work, for the first connecting tool 20A inserted at the distance between the upper frame member 2C and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are reinforced with the upper frame member 2C. Since the tilt angle with respect to the vertical direction, which is the direction of the distance from the member 7, is set to the opposite angle to each other, the door frame 2 is in an immovable state with respect to the auxiliary member 8 in the horizontal direction as well. It will be connected.

Further, as shown in FIGS. 16 and 17, two ends of the first connecting member 21 on the first connecting member 20A on the side of the auxiliary member 8 are shown in FIGS. 4 and 13. When the coupling tool 25 is connected to the auxiliary member 8 by inserting it into the second hole 29 of FIG. 7 provided in each connecting portion 26 of the first connecting member 21, as described with reference to FIG. 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 portion 26A on the auxiliary member 8 side decreases or disappears due to the load W, and at the end portion on the opposite side to the end portion 26A on the auxiliary member 8 side. A twist angle β is generated at the end 26B on the side of a certain door frame 2 as described above.

FIG. 18 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. 18, when a twist angle β occurs at the end 26B of the connecting portion 26 of each first connecting member 21 on the door frame 2 side, the twist angle β is the axis of the central axis 24. Since the angle is inclined with respect to the direction N, the hole 28, which is an insertion portion provided at the end 26B on the door frame 2 side for inserting 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 hole 28 is locked to the surface of the central shaft 24, in other words, the central shaft 24 becomes 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 connecting tool 20A in which the first connecting member 21 is a constituent member is in the thickness direction of the door frame 2 which is the axial direction N of the central shaft 24. It becomes immobile. Therefore, the door frame 2 is connected to the auxiliary member 8 which is the building material on the skeleton side in an immovable state in the thickness direction of the door frame 2.

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 threads 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, the auxiliary member 8 to which the first and second connecting members 21 and 22 are connected by the above-mentioned coupling tools 25 and 34 is attached to the reinforcing member 7 by the positioning member 10 shown in FIG. Since the door frame 2 is positioned and attached at a predetermined position in the thickness direction of 2, the corner portion 28A of the hole 28 is locked to the surface of the central shaft 24, so that the door frame 2 is placed in the thickness direction of the door frame 2. Will be positioned and placed at a predetermined position.

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 deformation such as bending to, a twist angle β is generated at the end 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 connecting tool 20A are connected to the auxiliary member 8. The coupling tools 25 and 34, which are two each, are arranged on opposite sides of the central axis 24 in the axial direction N as shown in FIGS. 16 and 17. 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.

In the embodiment shown in FIGS. 19 and 20, 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 first connecting tool 20A to the auxiliary member 8, the above is described. One binder 25 and another coupler 50 are used. These couplers 25 and 50 are 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 among these couplers 25 and 50, the coupler 50 Is arranged on the side of the two connecting portions 26D and 26E opposite to the same side on which the couplers 25 and 50 are arranged in the axial direction N of the central axis 24, as shown in FIG. 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.

As shown in FIG. 19, these fittings 50 and 51 include heads 50A and 51A, small diameter shaft portions 50B and 51B extending forward from these heads 50A and 51A, and these small diameter shaft portions. It is a tapping screw composed of large-diameter male threaded portions 50C and 51C extending forward from 50B and 51B. The diameters of the third holes 30 and 39 provided in the first and second connecting members 21 and 22 shown in FIGS. 7 and 9 are smaller and smaller than the diameters of the large diameter male screw portions 50C and 51C. It is larger than the diameter of the shaft portions 50B and 51B.

Therefore, while rotating the couplers 50 and 51 with the tool, the axial direction N of the central shaft 24 of the two connecting portions 26D, 26E, 35D, 35E of the first and second connecting members 21 and 22, respectively.
