Description

The present invention relates to a building material connecting device for connecting two building materials arranged at a distance from each other, and can be used, for example, to connect an opening frame, such as a door frame that is an equipment-side building material of a swing door device, sliding door device, etc., to a wall-side building material when the opening frame is placed in an opening in a wall.

The following Patent Document 1 shows a connecting device for connecting an opening frame such as a door frame and a wall-side building material, which are two building materials arranged at a distance from each other. This connecting device connects the two building materials with a number of connectors, and these connectors are arranged on one of the two building materials and include a base member with a central axis whose axial direction is the thickness direction of the one building material, and a connecting member that has a length extending from the base member toward the other building material and is connected to the other building material by a fastener. Of the two ends of the connecting member of each connector in the length direction, the end on the side of one building material has a hole through which the foundation member is inserted, and the end on the side of the other building material has a twist angle that is an inclination angle with respect to the axial direction of the foundation member. When the end on the side of the other building material is connected to the other building material with a connector, the twist angle decreases or disappears, causing the end on the side of one building material to have a twist angle with respect to the axial direction of the foundation member, which causes the end on the side of one building material to engage with the foundation member, and therefore the connecting member becomes immobile in the thickness direction of the one building material, and the two building materials are connected by multiple connectors with the one building material positioned in the thickness direction of the one building material.

There is a demand for reducing the cost of a device that uses multiple connectors to connect two building materials by positioning one of the building materials in the thickness direction of the other building material, and to achieve this, there is a demand for simplifying the structure of the connectors.

The object of the present invention is to provide a building material connecting device, its connecting structure, and its connecting method that can simplify the structure of the connectors to connect two building materials by positioning one building material in the thickness direction of the other building material using multiple connectors.

The building material connecting device according to the present invention is a building material connecting device for connecting two building materials arranged at a distance with a plurality of connecting devices, and each of the connecting devices is configured to include a base member that is placed on one of the two building materials and a connecting member that has a length extending from this base member toward the other building material and is connected to the other building material by a fastener, and the base member of each of the connecting devices is provided with a guide portion for guiding the connecting member so that it can move in a direction having a component in the thickness direction of the one of the building materials, and the connecting device is configured to move in a direction perpendicular to the direction of the distance and the thickness direction of the one of the building materials. At least two are provided on the one of the building materials, and the guide parts on the base members of these connectors have different inclination directions or angles with respect to the direction perpendicular to the spacing direction and the thickness direction of the one of the building materials, and before the connecting members arranged on the base members of each connector are connected to the other building material by the fasteners, each connecting member is guided by the guide parts and can move, and because each connecting member is connected to the other building material by the fasteners, each connecting member cannot be guided by the guide parts and cannot move.

In this way, the base member of the connector in the connection device for building materials according to the present invention is provided with a guide portion for guiding the connection member in a direction having a component in the thickness direction of the one building material, and at least two connectors are provided on the one building material in a direction perpendicular to the direction of the gap between the two building materials and the thickness direction of the one building material, and the guide portions of the base members of these connectors have different inclination directions or angles with respect to the direction perpendicular to the direction of the gap between the two building materials and the thickness direction of the one building material. Therefore, before the connection members arranged on each base member of each connector are connected to the other building material by the fastener, each connection member is guided by the guide portion and is movable, and by moving each connection member while being guided by the guide portion, the placement position of these connection members on the base member is adjusted in the thickness direction of the one building material, and after this, when each connection member is connected to the other building material by the fastener, each connection member becomes immobile in the thickness direction of the one building material.

Therefore, by performing the above-mentioned work of adjusting the position of each connecting member in the thickness direction of one of the building materials, the two building materials can be connected by positioning the one of the building materials in the thickness direction of the one of the building materials using multiple connecting devices.

In this way, two building materials are connected by using multiple connectors to position one of the building materials in the thickness direction of the one of the building materials. This can be achieved by simply making the guide parts of the base members of at least two connectors provided on the one of the building materials have different inclination directions or angles relative to the direction perpendicular to the spacing between the two building materials and the thickness direction of the one of the building materials. This can simplify the structure of the connectors, whose constituent members are the base members and the connector members.

The guide parts of the base members of at least two connectors provided on one of the building materials have different inclination directions or angles with respect to the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one of the building materials. This can be achieved by making each base member have the same shape and dimensions, and by making the guide parts provided on these base members have different inclination directions or angles with respect to the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one of the building materials when each base member is placed on the one of the building materials. Alternatively, each base member can have a different shape and dimensions, and by making the guide parts provided on these base members have different inclination directions or angles with respect to the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one of the building materials when each base member is placed on the one of the building materials.

According to the former, each base member can be made to have the same shape and dimensions, and the structure of the connector can be simplified by standardizing each base member. Note that making each base member the same shape and dimensions here includes cases where the manufactured base members contain differences in shape and dimensions due to processing errors.

In addition, in the above-described building material connecting device according to the present invention, the connector may be provided with a guide portion in any form. One example of the guide portion is that when the base member has an outer edge portion that extends in a direction that has a component in the thickness direction of the one of the building materials, this outer edge portion serves as the guide portion.

In addition, when the outer edge of the base member is used as the guide in this manner, if the base member has two outer edges that are parallel to each other, these outer edges may be used as the guide.

Another example of a guide part is a long hole formed in the base member that is long in a direction that has a component in the thickness direction of one of the building materials, and the long side of the inner surface of this long hole is used as the guide part.

If the long hole formed in the base member has two inner long sides that are parallel to each other, these inner long sides may be used as guide parts.

Furthermore, the guide portion provided on the base member may be a flat plate-like portion having a constant thickness dimension in the direction in which the connecting member is movable. In this way, the flat plate-like portion allows the connecting member to move smoothly.

Furthermore, when the guide section provided on the base member in this manner is a flat plate-like section with a constant thickness dimension in the direction in which the connecting member is movable, it is preferable to provide the connecting member with a slip-prevention section that is connected to the main body of the connecting member and faces the base member on the back side of the base member, and to insert a guide section of the base member that movably guides the connecting member between the slip-prevention section and the main body of the connecting member. In this way, the connecting member can be moved by being guided by the guide section, while the slip-prevention section prevents the connecting member from slipping off the guide section.

Providing a disconnection prevention part on the connecting member in this way can be achieved in various ways. One example is to provide a spanning part on the main body of the connecting member that spans the outside of the guide part, and to provide the disconnection prevention part at the end of this spanning part opposite the main body of the connecting member, protruding in a direction perpendicular to the direction of the gap between the two building materials and the thickness direction of one of the building materials. In this way, the connecting member can be more reliably prevented from disconnecting from the guide part by both the disconnection prevention part and the spanning part.

In addition, when the connecting member is provided with the above-mentioned slip prevention parts, if the connecting member has a width direction perpendicular to the direction of the gap between the two building materials and the thickness direction of one of the building materials, it is preferable to provide slip prevention parts on both sides of the connecting member in the width direction, and to provide these slip prevention parts at the same position in the direction perpendicular to the direction of the gap between the two building materials and the thickness direction of one of the building materials.

As described above, this allows the connecting members of at least two connectors provided on one building material to be standardized even if the guide portions of the base members of the at least two connectors provided on one building material are arranged with different inclination directions or angles with respect to the direction perpendicular to the spacing direction between the two building materials and the thickness direction of the one building material, and the respective base members are arranged on the one building material.

The connection structure of building materials according to the present invention is a connection structure of building materials for connecting two building materials arranged at a distance with a plurality of connectors, and each of the connectors is configured to include a base member arranged on one of the two building materials and a connecting member having a length extending from the base member toward the other building material and connected to the other building material by a fastener, and at least two of the connectors are provided on the one building material in a direction perpendicular to the direction of the distance and the thickness direction of the one building material, and the base member of these connectors is provided with a guide portion for movably guiding the connecting member in a direction having a component in the thickness direction of the one building material, The at least two connectors have different inclination directions or angles with respect to the direction of the spacing of the guide parts of the base members and the direction perpendicular to the thickness direction of the one building material, and the base members of the at least two connectors are arranged on the one building material, and before the connecting members arranged on each of the base members are connected to the other building material by the fasteners, each connecting member is guided by the guide parts and can move, and because each connecting member is connected to the other building material by the fasteners, each connecting member cannot be guided by the guide parts and cannot move.

In this connection structure of building materials, at least two connectors are provided on one of the building materials in a direction perpendicular to the direction of the gap between the two building materials and the thickness direction of the one of the building materials, and the base members of these connectors are provided with guide parts for guiding the connectors in a direction having a component in the thickness direction of the one of the building materials, and the at least two base members of the connectors are arranged on the one of the building materials with different inclination directions or inclination angles with respect to the direction perpendicular to the direction of the gap between the two building materials and the thickness direction of the one of the building materials for these guide parts. Then, before the connectors arranged on each base member of each connector are connected to the other building material by the connector, the connectors are moved by being guided by the guide parts, so that the positions of the connectors on the base member can be adjusted in the thickness direction of the one of the building materials, and then, by connecting each connector to the other building material by the connector, each connector becomes immobile in the thickness direction of the one of the building materials. Therefore, by performing the above-mentioned work of adjusting the position of each connecting member in the thickness direction of one of the building materials, the two building materials can be connected by positioning the one of the building materials in the thickness direction of the one of the building materials using multiple connecting devices.

In order to connect two building materials by positioning one of the building materials in the thickness direction of the one of the building materials using multiple connectors, the inclination direction or angle of the guide parts of the base members of at least two connectors provided on the one of the building materials with respect to the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one of the building materials may be changed in the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one of the building materials, and the base members of the at least two connectors may be arranged on the one of the building materials, thereby simplifying the structure of the connectors, whose constituent members are the base members and the connector members.

In addition, in this connection structure of building materials, in a direction perpendicular to the direction of the spacing between the two building materials and the thickness direction of the one of the building materials, the inclination direction or angle of the guide portion of the base member in at least two connectors provided on the one of the building materials with respect to the direction perpendicular to the spacing between the two building materials and the thickness direction of the one of the building materials is different, and by making each of the base members have the same shape and dimensions, it is possible to arrange the base members of the at least two connectors on the one of the building materials. When placed on one of the building materials, the inclination direction or angle of the guide portion of the base member relative to the direction of the spacing between the two building materials and the direction perpendicular to the thickness direction of the one of the building materials may be made different, or each of the base members may be made to have a different shape or different dimensions, so that when each of the base members is placed on one of the building materials, the inclination direction or angle of the guide portion of the base member relative to the direction of the spacing between the two building materials and the direction perpendicular to the thickness direction of the one of the building materials may be made different.

The method of connecting building materials according to the present invention is a method of connecting building materials for connecting two building materials arranged at a distance with a plurality of connectors, in which each connector includes a base member that is placed on one of the two building materials and a connecting member that has a length extending from this base member toward the other building material and is connected to this other building material by a fastener, and in the method of connecting building materials, the base members of at least two connectors are placed on one of the building materials in a direction perpendicular to the direction of the distance and the thickness direction of the one of the building materials, and the work of placing these base members on the one of the building materials is performed by attaching the connecting members to these base members in a direction having a component in the thickness direction of the one of the building materials. The method is characterized in that it includes a first work process for movably arranging the connecting members by guiding them with the guide parts for each of the base members in such a way that the inclination direction or inclination angle with respect to the direction of the spacing and the direction perpendicular to the thickness direction of the one of the building materials is different, a second work process for adjusting the arrangement positions of the connecting members on the base members in a direction having a component in the thickness direction of the one of the building materials by guiding each of the connecting members with the guide parts and moving them, and a third work process for connecting each of the connecting members to the other building material with the fasteners.

For this reason, in this method of connecting building materials, first, an operation is performed to place at least two foundation members of connectors on one of the building materials in a direction perpendicular to the direction of the spacing between the two building materials and the thickness direction of the one of the building materials, and this operation is performed by changing the inclination direction or inclination angle of guide parts provided on the foundation members to movably guide the connecting members in a direction having a component in the thickness direction of the one of the building materials with respect to the direction perpendicular to the direction of the spacing between the two building materials and the thickness direction of the one of the building materials, and an operation is also performed to movably arrange the connecting members by guiding them in the guide parts for each of the foundation members. Next, an operation is performed to adjust the placement positions of the connecting members on the foundation members in the thickness direction of the one of the building materials by guiding and moving each connecting member in the guide parts, and then an operation is performed to connect each connecting member to the other of the building materials with a fastener. Therefore, by adjusting the position of each connecting member in the thickness direction of one of the building materials as described above, when each connecting member is connected to the other building material with a fastener, the two building materials can be connected by positioning the one building material in the thickness direction of the one building material with multiple connectors.

In order to connect two building materials by positioning one of the building materials in the thickness direction of the one of the building materials using multiple connectors, at least two connectors are provided on the one of the building materials in a direction perpendicular to the direction of the spacing between the two building materials and the thickness direction of the one of the building materials, and the inclination direction or angle of the guide parts of the base member in these connectors relative to the direction of the spacing between the two building materials and the direction perpendicular to the thickness direction of the one of the building materials can be made different, which simplifies the structure of the connector, whose constituent members are the base member and the connector member.

In the first work step of the method for connecting building materials according to the present invention, the inclination direction or angle of the guide parts of the base members of at least two connectors in the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one building material may be made different by making the base members have the same shape and dimensions, so that when the base members are placed on the one building material, the inclination direction or angle of the guide parts of the base members in the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one building material may be made different, or the shape and dimensions of the base members may be different, so that when the base members are placed on the one building material, the inclination direction or angle of the guide parts of the base members in the direction perpendicular to the spacing direction of the two building materials and the thickness direction of the one building material may be made different.

The connecting member of the connector used in the connecting device, connecting structure, and connecting method of the building materials according to the present invention described above may be of any shape and structure. For example, the entire or almost entire connecting member may be plate-shaped, or the entire or almost entire connecting member may be L-shaped or U-shaped in cross section, for example, having a portion with a component in the thickness direction of one of the building materials and a portion with a component perpendicular to the direction of the gap between the two building materials and the thickness direction of one of the building materials.

The two building materials connected by the above-described connecting device, connecting structure, and connecting method of the building materials according to the present invention may be any building material. An example of such a building material is a building material on the wall side and an opening frame arranged opposite to this building material in the left-right or up-down direction. This opening frame may be, for example, a door frame for a hinged door device, an opening frame for a sliding door device, an opening frame for a passage opening formed in a wall, a fixed opening frame in which the members arranged inside are fixed, or a sash frame for a window, etc., and one of the two building materials may be a door pocket for storing a fire door that is normally opened from the door frame. The connecting device, connecting structure, and connecting method of the building materials according to the present invention may also be used to connect two building materials such as pillars, including intermediate pillars of a building, beams, cross bars, and surface materials, and the building materials to which they are applied are arbitrary.

The building material connecting device, connecting structure, and connecting method according to the present invention can be applied to building materials that are newly installed in structures such as buildings, and can also be applied to building materials that are renovated.

The present invention has the advantage that it is possible to connect two building materials by positioning one building material in the thickness direction of the other building material using multiple connectors, while simplifying the structure of the connectors.

FIG.

The following describes the embodiment of the present invention with reference to the drawings. Fig. 1 shows an overall front view of a hinged door device, in which a hinged door 1 is attached to a door frame 2 so as to be rotatable about a hinge 3, and the door frame 2 is disposed inside an opening 4A formed in a wall 4 of a building. Fig. 2 shows the door frame 2 before the hinged door 1 is attached. As shown in Fig. 2, the door frame 2 is an opening frame whose inside is an entrance 11 that is opened and closed by the hinged door 1, and since the door frame 2 of this embodiment is a four-sided frame, the door frame 2 is made up of left and right side frame members 2A, 2B, an upper frame member 2C, and a lower frame member 2D, which is a threshold member, and these frame members 2A, 2B, 2C, 2D are welded together in advance at a factory and transported to the construction site of a structure such as a building where the hinged door device is to be installed.

The door frame 2 may be a three-sided frame that does not have a bottom frame member 2D.

Figure 3 shows the arrangement of the door frame 2 in the wall 4 shown in Figures 1 and 2, and Figure 4 is a cross section taken along the line S4-S4 in Figure 3. The wall 4 shown in Figures 1 and 2 is formed by fastening a surface material 6 such as gypsum board to both the front and back sides of a core member 5, as shown in Figure 4, and the door frame 2 is arranged inside the opening 4A shown in Figures 1 and 2 provided in this wall 4. Figure 3 shows, of the many core members 5 provided inside the wall 4, core members 5A and 5B arranged with their length direction in the vertical direction at locations that face the left and right side frame members 2A and 2B of the door frame 2 in the left-right direction, and core member 5C arranged with their length direction in the left-right direction at a location that faces the upper frame member 2C of the door frame 2 in the up-down direction.

Before the door frame 2 is placed inside the opening 4A in the wall 4, the reinforcing members 7 shown in Figures 3 and 4 are already attached to the core members 5A, 5B, and 5C, and an auxiliary member 8 is attached to each of the reinforcing members 7 with the fasteners 9 shown in Figure 4. The auxiliary member 8 is made of an angle material with two plate-shaped protrusions 8A and 8B that form a right angle. Of these protrusions 8A and 8B, one protrusion 8A is connected to the reinforcing member 7 with the fasteners 9, and the other protrusion 8B protrudes toward the door frame 2.

In the above, the core member 5, reinforcing member 7, and auxiliary member 8 are members on the wall 4 side, so these core member 5, reinforcing member 7, and auxiliary member 8 are wall-side building materials. In contrast, the hinged door 1 and door frame 2 are members on the hinged door device side that is installed on the wall 4, so these hinged door 1 and door frame 2 are hinged door device-side building materials.

Figure 3 shows the state in which the door frame 2 has been connected to the reinforcing member 7 via the auxiliary member 8 by the connector 10 after the door frame 2 has been positioned inside the opening 4A of the wall 4. A plurality of connectors 10 for connecting the door frame 2 to the reinforcing member 7 via the auxiliary member 8 are provided for each of the left and right side frame members 2A, 2B and the top frame member 2C of the door frame 2. These connectors 10 include a first connector 10A and a second connector 10B. Figure 4 and Figure 5, which is a front view of Figure 4, show the first connector 10A, and Figure 6 shows the second connector 10B. As shown in FIG. 3, the first connector 10A connects the left and right side frame members 2A, 2B of the door frame 2 to the reinforcing members 7 attached to the core members 5A, 5B and facing the side frame members 2A, 2B in the left-right direction via the auxiliary member 8, and the first connector 10A also connects the upper frame member 2C of the door frame 2 to the reinforcing members 7 attached to the core member 5C and facing the upper frame member 2C in the up-down direction via the auxiliary member 8. The second connector 10B connects the left and right side frame members 2A, 2B of the door frame 2 to the reinforcing members 7 attached to the core members 5A, 5B and facing the side frame members 2A, 2B in the left-right direction via the auxiliary member 8.

As shown in FIG. 3, multiple first connectors 10A are arranged in the vertical direction, which is the length direction of the left and right side frame members 2A, 2B, and multiple connectors are arranged in the horizontal direction, which is the length direction of the upper frame member 2C, and one second connector 10B is arranged near the lower end of each of the left and right side frame members 2A, 2B. The second connector 10B may be omitted.

4 and 5, the first connector 10A is made up of a base member 20 arranged on the door frame 2 and a connecting member 21 arranged on the plate-shaped base member 20 in the thickness direction of the base member 20. The connecting member 21 is made up of a base portion 21A that is overlaid on the base member 20 and two connecting portions 21B, 21C that extend diagonally in opposite directions from the base portion 21A toward the auxiliary member 8. The tips of these connecting portions 21B, 21C are connected to the plate-shaped protruding piece portion 8B of the auxiliary member 8 by a fastener 24, which is a drill screw, as shown in FIG. As shown in FIG. 6, the second connecting member 10B also consists of a base member 22 placed on the door frame 2 and a connecting member 23 placed on the plate-shaped base member 22 in the thickness direction of the base member 22. The connecting member 23 consists of a base portion 23A that is placed on the base member 22 and a connecting portion 23B that extends diagonally from the base portion 23A toward the auxiliary member 8. The tip of the connecting portion 23B is connected to the plate-shaped protruding piece portion 8B of the auxiliary member 8 by a fastener 25 that is a drill screw.

The connecting portions 21B, 21C, and 23B of the connecting members 21 and 23 of the first and second connectors 10A and 10B are bent relative to the base portions 21A and 23A, so that they extend obliquely from the base portions 21A and 23A toward the auxiliary member 8. Figures 8(A) to 8(D) show a plan view, a right side view, a front view, and a left side view of the door frame 2 before the connecting portions 21B, 21C, and 23B are bent relative to the base portions 21A and 23A. As can be seen from these Figures 8(A) to 8(D), the base members 20 and 22 of the first and second connectors 10A and 10B arranged on the side frame members 2A and 2B and the top frame member 2C of the door frame 2 are formed of rectangular metal plates and have the same shape and dimensions.

The foundation members 20, 22 are fixed by welding to the left and right side frame members 2A, 2B and the top frame member 2C, which are the components of the door frame 2, in the factory where the door frame 2 is manufactured. That is, as shown in FIG. 7, of the left and right side frame members 2A, 2B and the top frame member 2C of the door frame 2, multiple foundation members 20 and one foundation member 22 are fixed by welding to each of the side frame members 2A, 2B at the factory, and multiple foundation members 20 are fixed by welding to the top frame member 2C at the factory.

As can be seen from Figures 7(A) to (D), which are the plan view, right side view, front view and left side view of the door frame 2, the work of fixing a plurality of foundation members 20 and one foundation member 22 to each of the side frame members 2A, 2B by welding these foundation members 20, 22 is performed by tilting these foundation members 20, 22 in a direction perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary members 8 on the core members 5A, 5B side of the wall 4 and the thickness direction of the door frame 2, i.e., in the vertical direction which is the length direction of the side frame members 2A, 2B, while reversing the tilt direction of these foundation members 20, 22 relative to the vertical direction in turn and keeping the absolute tilt angles of these foundation members 20, 22 (the tilt angles of the foundation members 20, 22 excluding the vertical tilt directions) the same. In addition, the work of fixing the multiple foundation members 20 to the upper frame member 2C by welding is performed by tilting these foundation members 20 in a direction perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4 and the thickness direction of the door frame 2, that is, in the left-right direction which is the length direction of the upper frame member 2C, while reversing the tilt direction of these foundation members 20 relative to the left-right direction and making the absolute tilt angles of these foundation members 20 (the tilt angles of the foundation members 20, 22 excluding the left-right tilt directions) the same.

9 shows an enlarged view of the first connector 10A of the first connector 10A and the second connector 10B shown in FIG. 8, and FIG. 10 and FIG. 11 show only the connector 21 of the base member 20 and the connector 21 that are the components of the first connector 10A. FIG. 10(A) and (B) show a side view and a front view of the connector 21, and FIG. 11 is a perspective view of the connector 21. As can be seen from FIG. 10 and FIG. 11, the connector 21 is manufactured by punching, bending, curling, etc., on a metal plate, and two connectors 21B and 21C extend in opposite directions from the base 21A described above. The left-right direction in FIG. 10(A) is the width direction of the connector 21, which is the thickness direction of the door frame 2 described above.

The two connecting parts 21B, 21C of the connecting member 21 have the same width and the same extension length from the base part 21A, and the width of the two connecting parts 21B, 21C is smaller than the width of the base part 21A, which is also the main body of the connecting member 21. Therefore, at the boundary between the base part 21A and the two connecting parts 21B, 21C, a step part 26 in the width direction due to the difference in these width dimensions is provided. In addition, long holes 27 that are long in the width direction are formed in the base part on the base part 21A side of the connecting parts 21B, 21C near these boundaries, and these long holes 27 are through holes that penetrate the thickness direction of the connecting member 21.

Furthermore, at the ends of the two connecting parts 21B, 21C on both widthwise sides of the base part 21A, four spanning parts 28 that protrude in a direction perpendicular to the width direction of the connecting member 21 and the extension direction of the connecting parts 21B, 21C, i.e., in the thickness direction of the connecting member 21, are formed and connected to the base part 21A, and as shown in Figure 12, when the base part 21A of the connecting member 21 is placed on the foundation member 20, these spanning parts 28 straddle the outside of the foundation member 20, which is a plate-shaped member. A detachment prevention part 29 is formed at the tip of each spanning part 28, which is the end opposite the base part 21A side. Of these removal prevention parts 29, two are provided on each of the two connecting parts 21B and 21C, and protrude from the straddling part 28 toward the inside of the base part 21A, which is on the opposite side. Therefore, these removal prevention parts 29 protrude in directions facing each other.

The direction in which these anti-detachment portions 29 protrude is the up-down direction, which is perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary member 8 on the core member 5A, 5B side of the wall 4, and the thickness direction of the door frame 2, for the connecting member 21 whose base portion 21A is superimposed on the foundation member 20 arranged on the side frame members 2A, 2B of the door frame 2 in the thickness direction of the foundation member 20; and the left-right direction, which is perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4, and the thickness direction of the door frame 2, for the connecting member 21 whose base portion 21A is superimposed on the foundation member 20 arranged on the upper frame member 2C in the thickness direction of the foundation member 20.

As a result, when the base portion 21A of the connecting member 21 is placed on the foundation member 20 of the first connector 10A, which is fixed to the side frame members 2A, 2B and top frame member 2C of the door frame 2, the two of these anti-removal portions 29 that are arranged diagonally on the base portion 21A face the back side of the foundation member 20, as the spanning portion 28 at the tip of which these anti-removal portions 29 straddles the outside of the foundation member 20.

As shown in FIG. 10(A), the tip of the two connecting parts 21B, 21C is provided with a cylindrical part 30 formed by curling the plate-like connecting parts 21B, 21C. In addition, a notch 31 is formed in each connecting part 21B, 21C at the center of the width of each connecting part 21B, 21C, cutting from the tip side of each connecting part 21B, 21C toward the base part 21A, and each cylindrical part 30 is divided into two divided cylindrical parts 30A by this notch 31.

Figure 13 shows an enlarged view of the second connector 10B of the first connector 10A and second connector 10B shown in Figure 8, and Figure 14 shows a perspective view of only the connector 23 of the base member 22 and connector 23 that are components of the second connector 10B. As can be seen from Figure 14, this connector 23 is also manufactured by punching, bending, curling, etc., a metal plate, and one connector 23B extends from the base portion 23A described above. The width direction of this connector 23 is the same as the width direction of the connector 21 of the first connector 10A, and this width direction is also the thickness direction of the door frame 2 described above.

The connecting member 23 of the second connecting device 10B is the same as the connecting member 21 of the first connecting device 10A, with one connecting portion 21C omitted, out of the two connecting portions 21B, 21C provided on the connecting member 21. Therefore, the base portion 23A and the connecting portion 23B of the connecting member 23 correspond to the base portion 21A and the connecting portion 21B of the connecting member 21, and since the width dimension of the connecting portion 23B is smaller than the width dimension of the base portion 23A, which is also the main body of the connecting member 23, a step portion 36 in the width direction due to the difference in these width dimensions is provided at the boundary between the base portion 23A and the connecting portion 23B, and a long hole 37 that penetrates the connecting member 23 in the thickness direction and is elongated in the width direction of the connecting member 23 is formed at the base portion on the base portion 23A side of the connecting portion 23B near this boundary. In addition, at the end of the connecting portion 23B side on both sides of the width direction of the base portion 23A and the end opposite to this end, four spanning portions 38 connected to the base portion 23A are formed in a direction perpendicular to the width direction of the connecting member 23 and the extension direction of the connecting portion 23B, that is, in the thickness direction of the connecting member 23, similar to the spanning portions 28 in the connecting member 21 of the first connecting device 10A. These spanning portions 38 span the outside of the base member 22, which is a plate-shaped member, when the base portion 23A of the connecting member 23 is placed over the base member 22 of the second connecting device 10B, which is fixed to the side frame members 2A and 2B of the door frame 2, as shown in FIG. 18.

A slip prevention part 39 is formed at the tip of each straddling part 38, which is the end opposite the base part 23A side. Of these slip prevention parts 39, two slip prevention parts 39 are provided at the end on the connecting part 23B side and the end opposite this end, and each of them protrudes from the straddling part 38 toward the inside of the base part 23A, which is opposite to each other, and these slip prevention parts 39 protrude in a direction facing each other. Therefore, when the connecting member 23 is arranged by overlapping the base part 23A of the connecting member 23 on the foundation member 22 fixedly arranged on the side frame members 2A and 2B of the door frame 2, the two slip prevention parts 39 that are arranged in the diagonal direction of the base part 23A among these slip prevention parts 39 face the foundation member 22 on the back side of the foundation member 22, as the straddling part 38 with the slip prevention parts 39 provided at the tip straddles the outside of the foundation member 22.

As shown in FIG. 14, a cylindrical portion 40 is provided at the tip of the connecting portion 23B by curling the plate-shaped connecting portions 21B and 21C, and a notch 41 is formed in the center of the width of the connecting portion 23B, cutting from the tip side of the connecting portion 23B toward the base portion 23A. This notch 41 divides the cylindrical portion 40 into two separate cylindrical portions 40A.

As described above, of the four anti-detachment portions 29 provided on the connecting member 21 of the first connector 10A, the two anti-detachment portions 29 arranged in the diagonal direction of the base portion 21A are placed face-to-face with the back side of the foundation members 20 fixed to the side frame members 2A, 2B and top frame member 2C of the door frame 2, and the base portion 21A of the connecting member 21 is overlapped on the foundation member 20 in the thickness direction of the foundation member 20. Also, of the four anti-detachment portions 39 provided on the connecting member 23 of the second connector 10B, the two anti-detachment portions 39 arranged in the diagonal direction of the base portion 23A are placed face-to-face with the back side of the foundation members 22 fixed to the side frame members 2A, 2B of the door frame 2, and the base portion 23A of the connecting member 23 is overlapped on the foundation member 22 in the thickness direction of the foundation member 22. These operations are carried out after the door frame 2 is transported from the factory to the installation site of the opening device shown in FIG. 1. These operations are performed by changing the orientation of the connecting members 21, 23 of the first and second connectors 10A, 10B to a position perpendicular to the base members 20, 22, which are tilted relative to the side frame members 2A, 2B and top frame member 2C of the door frame 2, and then changing the orientation of the connecting members 21, 23 to a position parallel to the length direction of the side frame members 2A, 2B and top frame member 2C of the door frame 2.

The above-mentioned work may be performed before the door frame 2 is transported from the factory to the installation site of the opening device shown in FIG. 1 by making the protrusions of the anti-detachment parts 29, 39 from the respective straddling parts 28, 38 sufficiently large, and inserting the foundation members 20, 22 laterally between the base parts 21A, 23A of the connecting members 21, 23 and the anti-detachment parts 29, 39 before the foundation members 20, 22 are fixed to the side frame members 2A, 2B and the upper frame member 2C of the door frame 2 by welding in the factory.

After the first and second connectors 10A, 10B are placed in the door frame 2 by the above-mentioned operations, the door frame 2 is inserted into the inside of the opening 4A of the wall 4 described in Figure 2 and the like before the face material 6 of the wall 4 shown in Figure 4 is fastened to the core member 5. When this operation is performed, the connecting portions 21B, 21C, 23B of the connecting members 21, 23 of the first and second connectors 10A, 10B are not yet bent, so they are flat against the base portions 21A, 23A and extend from these base portions 21A, 23A in the length direction of the side frame members 2A, 2B and the upper frame member 2C. Therefore, even if the gap in the left-right direction between the side frame members 2A, 2B of the door frame 2, which are the two building materials connected by the first and second connectors 10A, 10B, and the auxiliary member 8 on the core member 5A, 5B side of the wall 4 is small, and the gap in the up-down direction between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4 is small, the door frame 2 can be easily inserted into the opening 4A of the wall 4.

After this, the connecting members 21, 23 of the first and second connectors 10A, 10B are moved in the thickness direction of the door frame 2 using the base members 20, 21 as guide members, to adjust the position of these connecting members 21, 23 on the base members 20, 22. This adjustment is a positioning operation for positioning the door frame 2 in the thickness direction of the wall 4 to a predetermined position so that, for example, the center of the door frame 2 in the thickness direction and the center of the wall 4 in the thickness direction coincide with each other when the side frame members 2A, 2B and the auxiliary member 8 on the core member 5A, 5B side of the wall 4 are connected by the first and second connectors 10A, 10B, and the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4 are connected by the first connector 10A.

As shown in Figures 9 and 13, the foundation members 20, 22 are formed from horizontally long rectangular plate material, so that the connecting members 21, 23 of each of the first and second connectors 10A, 10B are moved in the thickness direction of the door frame 2 using the base members 20, 22 as guide members. For the base members 20, 22 arranged on the side frame members 2A, 2B of the door frame 2, the outer edge portions 20A, 20B, 22A, 22B which are spaced apart in the longitudinal direction of the side frame members 2A, 2B serve as guide portions, and for the base member 20 arranged on the upper frame member 2C, the outer edge portions 20A, 20B which are spaced apart in the longitudinal direction of the upper frame member 2C serve as guide portions. At this time, of the four detachment prevention parts 29, 39 provided at the ends of the spanning parts 28, 38 connected to the base parts 21A, 23A that form the main body of the connecting members 21, 23, the two detachment prevention parts 29, 39 provided in the diagonal direction of the base parts 21A, 23A face the back side of the foundation members 20, 22, so that the connecting members 21, 23 can be prevented from detaching from the outer edge parts 20A, 20B, 22A, 22B inserted between these detachment prevention parts 29, 39 and the base parts 21A, 23A.

In addition, since the base members 20, 22 are flat as a whole, the guide portions formed by the outer edge portions 20A, 20B, 22A, 22B are formed in the flat portions of the base members 20, 22 that have a constant thickness dimension in the direction in which the connecting members 21, 23 are moved. This allows the connecting members 21, 23 to be moved smoothly while being guided by the guide portions.

As mentioned above, the foundation members 20, 22 of the first and second connectors 10A, 10B which are fixedly arranged on the side frame members 2A, 2B of the door frame 2 are inclined in the up-down direction, which is a direction perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary members 8 on the core members 5A, 5B side of the wall 4, and to the thickness direction of the door frame 2. Therefore, the above-mentioned guide portions formed by the parallel outer edge portions 20A, 20B, 22A, 22B of the foundation members 20, 22 have a component in the thickness direction of the door frame 2 and a component in the up-down direction perpendicular to this thickness direction. In addition, the base member 20 of the first connector 10A, which is fixed to the upper frame member 2C of the door frame 2, is tilted in the left-right direction, which is a direction perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4, and to the thickness direction of the door frame 2. Therefore, the guide portion formed by the parallel outer edges 20A, 20B of the base member 20 has a component in the thickness direction of the door frame 2 and a component in the left-right direction perpendicular to this thickness direction.

As described above, when the connecting members 21, 23 of the first and second connectors 10A, 10B are moved in the thickness direction of the door frame 2 using the base members 20, 22 as guide members, the connecting members 21, 23 guided by the guide portions of the base members 20, 22 arranged on the side frame members 2A, 2B of the door frame 2 move in a direction having a component in the thickness direction of the door frame 2 and a component in the up-down direction, and the connecting member 21 guided by the guide portion of the base member 20 arranged on the top frame member 2C moves in a direction having a component in the thickness direction of the door frame 2 and a component in the left-right direction.

After adjusting the positions of the connecting members 21, 23 on the foundation members 20, 22 in this way, the position of the door frame 2 within the opening 4A of the wall 4 is moved in the left-right direction, which is the direction of the gap between the side frame members 2A, 2B and the auxiliary members 8 on the core members 5A, 5B side of the wall 4 as shown in Figure 3, to bring the position of the door frame 2 to the appropriate position in the left-right direction.

Next, the operation of bending the connecting portions 21B, 21C, and 23B of the connecting members 21 and 23 of the first and second connecting devices 10A and 10B relative to the base portions 21A and 23A is performed. FIG. 15 shows, as a representative example, the bending operation of the first connecting device 10A arranged on the side frame member 2A of the door frame 2, and FIG. 19 shows, as a representative example, the bending operation of the second connecting device 10B arranged on the side frame member 2A of the door frame 2, relative to the base portion 23A of the connecting members 23 of the second connecting devices 10B.

The operation of bending the two connecting portions 21B, 21C of the connecting member 21 in the first connecting device 10A relative to the base portion 21A is performed using an operating tool 50 shown in Fig. 15. This operating tool 50 includes a gripping portion 51 that is held by the operator, a bifurcated portion 52 having two branches 52A, 52B branching out and extending from the gripping portion 51, and a buffer member 53 attached to the base of the bifurcated portion 52. After inserting each of the branches 52A, 52B into the backside of the two connecting parts 21B, 21C of the connecting member 21 and abutting the buffer member 53 against the outer surface of the door frame 2, the worker rotates the grip part 51 in the direction of the arrow, using the buffer member 53 as a fulcrum. This causes the connecting parts 21B, 21C to bend relative to the base part 21A as shown in FIG. 16, so that the connecting parts 21B, 21C can be oriented diagonally toward the wall 4.

The operation of bending the connecting portion 23B of the connecting member 23 in the second connecting device 10B shown in FIG. 19 is also performed using the operating tool 50. This bending operation is performed by inserting one of the two branches 52A, 52B, the branch 52A, into the back side of the connecting portion 23B, and then abutting the buffer member 53 against the outer surface of the door frame 2 in the same manner as in the first connecting portion 10A. The worker then rotates the gripping portion 51 in the direction of the arrow, using the buffer member 53 as a fulcrum. As a result, the connecting portion 23B is bent relative to the base portion 23A as shown in FIG. 20, and the connecting portion 23B can be oriented diagonally toward the wall 4.

The reason why the connecting portion of the connecting member 23 in the second connecting device 10B has only one connecting portion 23B, unlike the two connecting portions 21B and 21C of the connecting member 21 in the first connecting device 10A, is that, as mentioned above, the second connecting portion 10B is arranged near the lower ends of the side frame members 2A and 2B of the door frame 2, and this arrangement can be performed without interfering with the floor or the like on which the hinged door device is installed.

When the connecting portions 21B, 21C, and 23B of the connecting members 21 and 23 of the first and second connecting devices 10A and 10B are bent relative to the base portions 21A and 23A in the above manner, as can be seen from FIG. 4, which shows the connecting portion 21B of the connecting member 21 of the first connecting device 10A arranged on the side frame member 2A, the two connecting portions 21B and 21C of the connecting member 21 of the first connecting device 10A and the connecting portion 23B of the connecting member 23 of the second connecting device 10B approach the auxiliary member 8 attached to the aforementioned reinforcing member 7 of the wall 4, and when further bending is performed, the plate-shaped protruding portion 8B of this auxiliary member 8 protruding toward the door frame 2 can be inserted into the inside of the cut portions 31 and 41 formed in the connecting portions 21B, 21C, and 23B.

After that, as shown in Fig. 17 and Fig. 21, the shafts 24A, 25A of the fasteners 24, 25, which are the drill screws described above, are inserted into the cylindrical parts 30, 40 formed at the tip of the connecting parts 21B, 21C, 23B, and the fasteners 24, 25 are rotated with an electric tool or the like, so that the tip of the shafts 24A, 25A threads the plate-shaped protruding piece 8B of the auxiliary member 8, while the tip of the connecting parts 21B, 21C, 23B is fastened to the respective auxiliary members 8 by the fasteners 24, 25. As a result, the door frame 2 is connected to the respective reinforcing members 7 provided on the wall 4 opposite the side frame members 2A, 2B and the upper frame member 2C of the door frame 2 through the auxiliary members 8 by the first and second connectors 10A, 10B.

When connecting the tips of the connecting parts 21B, 21C, 23B to the respective auxiliary members 8 with the connecting parts 24, 25 while threading the protruding piece 8B of the auxiliary member 8 with the tips of the shaft parts 24A, 25A of the connecting parts 24, 25, it is preferable to press the tips of the connecting parts 21B, 21C, 23B against the surface of the protruding piece 8A of the auxiliary member 8 by continuously pressing the connecting parts 21B, 21C, 23B with the branches 52A, 52B of the operating tool 50 as shown in Figures 17 and 21. This prevents the connecting parts 21B, 21C, 23B from vibrating or otherwise moving slightly during threading, making it easier to process the threaded holes.

According to the first and second connectors 10A and 10B of the present embodiment described above, the connectors 21 and 23, which are used to connect the door frame 2 and the auxiliary member 8 of the wall 4, can be bent relative to the bases 21A and 23A of the connectors 21 and 23. By bending the connectors 21 and 23, the ends of the connectors 21 and 23 can be joined to the auxiliary member 8 by fasteners 24 and 25, simplifying the structure of the connectors 21 and 23, and thus simplifying the structure of the entire connectors 10A and 10B.

Furthermore, when the tips of connecting portions 21B, 21C, 23B are connected to the respective auxiliary members 8 by fasteners 24, 25 through the above-described procedure, in the first connector 10A connecting the side frame members 2A, 2B of the door frame 2 to the auxiliary member 8 on the core member 5A, 5B side of the wall 4, as shown in FIG. 17, of the two connecting portions 21B, 21C provided on the connector member 21 of this first connector 10A, one connecting portion 21B is inclined upwards and connected to the auxiliary member 8 on the core member 5A, 5B side of the wall 4, and the other connecting portion 21C is inclined downwards and connected to the auxiliary member 8 on the core member 5A, 5B side of the wall 4. For this reason, the angles that these connecting parts 21B, 21C make with respect to the left-right direction, which is the direction of the gap between the door frame 2 and the auxiliary members 8 on the core members 5A, 5B side of the wall 4, are different, and the two connecting parts 21B, 21C are at an angle. Therefore, the connecting parts 21B, 21C can immobilize the door frame 2 in the up-down direction, which is perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary members 8 on the core members 5A, 5B side of the wall 4, and to the thickness direction of the door frame 2.

Furthermore, in the first connector 10A connecting the upper frame member 2C of the door frame 2 to the auxiliary member 8 on the core member 5C side of the wall 4, although not shown in the drawings, of the two connecting portions 21B, 21C provided on the connecting member 21 of this first connector 10A, one connecting portion 21B is inclined to one side in the left-right direction and connected to the auxiliary member 8 on the core member 5C side of the wall 4, and the other connecting portion 21C is inclined to the other side in the left-right direction and connected to the auxiliary member 8 on the core member 5C side of the wall 4. For this reason, the angles that these connecting parts 21B, 21C make with respect to the vertical direction, which is the direction of the gap between the door frame 2 and the auxiliary member 8 on the core member 5C side of the wall 4, are different, and the two connecting parts 21B, 21C are at an angle, so that the door frame 2 can be immobilized in the left-right direction, which is perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4, and the thickness direction of the door frame 2, by the connecting parts 21B, 21C.

Furthermore, as described above, each of the foundation members 20 of the first connector 10A, of which a plurality are arranged on the side frame members 2A, 2B, is tilted in the vertical direction, which is a direction perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary members 8 on the core members 5A, 5B side of the wall 4, and to the thickness direction of the door frame 2, and the inclination direction of these foundation members 20 in the vertical direction is reversed in sequence, and these foundation members 20 are arranged on the side frame members 2A, 2B with the same absolute inclination angle, so that the aforementioned guide portion formed by the outer edge portions 20A, 20B of the foundation members 20, which are parallel to each other, also has the same inclination direction and inclination angle as these foundation members 20.

As a result, some of the guide sections provided on these base members 20 have different inclination directions relative to the vertical direction.

The foundation members 20 of the first connectors 10A arranged in the upper frame member 2C are inclined in the left-right direction, which is a direction perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4 and the thickness direction of the door frame 2, and are arranged on the upper frame member 2C with the inclination directions of the foundation members 20 in the left-right direction reversed and with the same absolute inclination angle. Therefore, the aforementioned guide portion formed by the outer edge portions 20A, 20B of the foundation members 20, which are parallel to each other, also has the same inclination direction and inclination angle as the foundation members 20.

As a result, some of the guide sections provided on these base members 20 have different inclination directions relative to the left and right direction.

Therefore, after the tip of each connecting member 21 is connected to the auxiliary member 8 by the fasteners 24, 25, the door frame 2 connected to each reinforcing member 7 of the wall 4 by the first and second connecting members 10A, 10B via the auxiliary members 8 cannot move in the thickness direction of the door frame 2 relative to the first and second connecting members 10A, 10B, and is therefore immobile in the thickness direction of the door frame 2. As a result, before the tip of each connecting member 21 is connected to the auxiliary member 8 by the fasteners 24, 25, the connecting member 21 is guided by the guide portion of the base member 20 to move. For example, when the door frame 2 is placed at a predetermined position in the thickness direction of the wall 4 by aligning the center of the thickness direction of the door frame 2 with the center of the thickness direction of the wall 4 as described above, the door frame 2 can be positioned at a predetermined position in the thickness direction of the door frame 2 and connected to the reinforcing member 7 of the wall 4 by the first and second connecting members 10A, 10B via the auxiliary members 8.

Therefore, according to this embodiment, the door frame 2 and the auxiliary member 8 on the wall 4 side, which are two building materials, can be connected by positioning the door frame 2 in the thickness direction of the door frame 2 using multiple first and second connectors 10A, 10B, by arranging the multiple foundation members 20 on the side frame members 2A, 2B and the upper frame member 2C at different inclinations, thereby simplifying the structure of the first connector 10A.

In this embodiment, after the tip end of the connecting member 21 of each first connecting device 10A is connected to the auxiliary member 8 by the fasteners 24, 25 as described above, the door frame 2 is positioned in the thickness direction of the door frame 2 to be immobilized. This is done by tilting the foundation members 20 arranged on the side frame members 2A, 2B of the door frame 2 in the vertical direction, which is a direction perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary member 8 on the core member 5A, 5B side of the wall 4 and the thickness direction of the door frame 2, and by reversing the tilt direction of these foundation members 20 relative to the vertical direction in order and making the absolute tilt angle of these foundation members 20 the same. Also, for the foundation members 20 arranged on the upper frame member 2C, In this case, the door frame 2 is immobilized in the thickness direction of the door frame 2 by tilting the foundation members 20 in the left-right direction, which is perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4, and by reversing the tilt direction of these foundation members 20 in the left-right direction and making the absolute tilt angles of these foundation members 20 the same. However, for the foundation members 20 arranged in multiple positions on the side frame members 2A and 2B, the tilt direction of these foundation members 20 in the up-down direction can be made the same but with different tilt angles, and for the foundation members 20 arranged in multiple positions on the upper frame member 2C, the tilt direction of these foundation members 20 in the left-right direction can be made the same but with different tilt angles, so that the door frame 2 cannot move in the thickness direction of the door frame 2.

The door frame 2 can also be immobilized in the thickness direction by not tilting some of the foundation members 20 arranged in multiple positions on the side frame members 2A and 2B in the vertical direction while tilting the other foundation members 20 in the vertical direction, and by not tilting some of the foundation members 20 arranged in multiple positions on the top frame member 2C in the horizontal direction while tilting the other foundation members 20 in the horizontal direction.

In addition, according to this embodiment, the base members 20, 22 of the first and second connectors 10A, 10B are of the same shape and dimensions, so the first and second connectors 10A, 10B can be produced using the same base members 20, 22.

In addition, by making the base members 20 of the first connectors 10A have different vertical directions and inclination angles for the side frame members 2A and 2B of the door frame 2, and different horizontal directions and inclination angles for the top frame member 2C, even if they are arranged on the side frame members 2A and 2B and the top frame member 2C, the connecting members 21 have anti-detachment sections 29 on both sides of the width of the connecting members 21 at the same positions in the length direction of the side frame members 2A and 2B for the connecting members 21 arranged on the side frame members 2A and 2B, and at the same positions in the length direction of the top frame member 2C for the connecting members 21 arranged on the top frame member 2C. Therefore, of the four anti-detachment sections 29, the two anti-detachment sections 29 arranged diagonally face the back side of the base member 20, and therefore the connecting members 21 can be made common to these base members 20.

Furthermore, the connecting member 23 of the second connecting device 10B according to this embodiment is the same as the connecting member 21 of the first connecting device 10A, with the connecting portion 21C omitted, out of the two connecting portions 21B and 21C provided thereon. Therefore, this connecting member 23 can be easily produced by performing a process to remove the connecting portion 21C from the connecting member 21.

In addition, the tip ends of the connecting portions 21B, 21C, 23B of the connecting members 21, 23 of the first and second connectors 10A, 10B are connected to the auxiliary member 8 by the fasteners 24, 25, which are drill screws that connect the plate-shaped protruding piece 8B of the auxiliary member 8 to the fasteners 24, 25. Therefore, prior to this connecting operation, as described above, the position of the door frame 2 within the opening 4A of the wall 4 is determined by the distance between the side frame members 2A, 2B and the auxiliary members 8 on the core members 5A, 5B side of the wall 4 as shown in FIG. Even if the door frame 2 is moved left and right to the correct position in the left and right direction, the angle between the two connecting parts 21B, 21C of the connecting member 21 of the first connecting part 10A, among the first and second connecting parts 10A, 10B arranged on the side frame members 2A, 2B, and the angle between the connecting part 23B of the connecting member 23 of the second connecting part 10B and the auxiliary member 8 changes, and the tips of the connecting parts 21B, 21C, 23B can be connected to the auxiliary member 8 as specified by the fasteners 24, 25.

In addition, when the position of the door frame 2 is changed vertically to set the position of the door frame 2 in the opening 4A of the wall 4 to the appropriate position in the vertical direction, the angle formed by the two connecting portions 21B, 21C of the connecting member 21 of the first connector 10A arranged on the upper frame member 2C changes, and the tips of these connecting portions 21B, 21C can be connected as specified to the auxiliary member 8 attached to the core member 5C of the wall 4 facing the upper frame member 2C.

Furthermore, the work of connecting the tips of the connecting parts 21B, 21C, and 23B to the auxiliary member 8 using the fasteners 24 and 25 is performed by inserting the shafts 24A and 25A of the fasteners 24 and 25 into the cylindrical parts 30 and 40 provided at the tips of the connecting parts 21B, 21C, and 23B as shown in Figures 17 and 21. Therefore, while these shafts 24A and 25A are guided by the cylindrical parts 30 and 40, the shafts 24A and 25A can be used to machine a threaded hole in the plate-shaped protruding piece 8B of the auxiliary member 8.

In addition, the connecting parts 21B, 21C, and 23B are provided with cutouts 31, 41 that divide the tubular parts 30, 40 into two separate tubular parts 30A, 40A, respectively. The protruding piece 8B of the auxiliary member 8 is inserted into these cutouts 31, 41, and the protruding piece 8B is threaded by the shaft parts 24A, 25A of the fasteners 24, 25. This allows the shaft parts 24A, 25A to be guided by the tubular parts 30, 40 both immediately before the protruding piece 8B is threaded by the shaft parts 24A, 25A of the fasteners 24, 25 and immediately after the threaded hole has been formed.

Furthermore, after the tips of the connecting parts 21B, 21C, and 23B are connected to the protruding piece 8B of the auxiliary member 8 by the fasteners 24 and 25, the plate-shaped protruding piece 8B is sandwiched between the two divided tubular parts 30A and 40A, so that the connecting members 21 and 23 to which the connecting parts 21B, 21C, and 23B are attached can be prevented from moving in the length direction of the tubular parts 30 and 40, i.e., in the thickness direction of the door frame 2.

In addition, the cylindrical portions 30, 40 are formed by curling the tip portions of the plate-shaped connecting members 21, 23, so that the cylindrical portions 30, 40 can be more easily attached to the connecting members 21, 23 than when the cylindrical portions 30, 40 are attached to the tip portions of the connecting members 21, 23 by welding or the like.

In addition, since the entire connecting members 21, 23 of the first and second connectors 10A, 10B according to the present embodiment are formed from metal plates, the boundary between the base portion 21A, 23A and the connecting portions 21B, 21C, 23B and the vicinity of the boundary are flat, with the bending direction of the connecting portions 21B, 21C, 23B relative to the base portion 21A, 23A being the thickness direction. This makes it easy to fold the connecting portions 21B, 21C, 23B using the operating tool 50.

In addition, as described above, at the boundary between the base portions 21A, 23A and the connecting portions 21B, 21C, 23B, there are step portions 26, 36 due to the difference in width between the base portions 21A, 23A and the connecting portions 21B, 21C, 23A. These step portions 26, 36 are strength reducing portions for reducing the bending strength of the connecting portions 21B, 21C, 23B relative to the base portions 21A, 23A. In this respect, too, the operation of bending the connecting portions 21B, 21C, 23A with the operating tool 50 can be easily performed.

Furthermore, near the boundary between the base portions 21A, 23A and the connecting portions 21B, 21C, 23B, as described above, long holes 27, 37 that are long in the thickness direction of the door frame 2, which is also the width direction of the connecting members 21, 23, are formed penetrating the thickness direction of the connecting members 21, 23. These long holes 27, 37 also serve as strength reduction portions for reducing the bending strength of the connecting portions 21B, 21C, 23B relative to the base portions 21A, 23A, so that the bending operation of the connecting portions 21B, 21C, 23A can be easily performed using the operating tool 50.

Figure 22 shows a first connector 60A according to another embodiment. This first connector 60A is also composed of a rectangular base member 70 made of a metal plate fixed to the door frame 2, and a connecting member 71 arranged on the base member 70 in a thickness direction of the base member 70. The connecting member 71 has a base portion 71A arranged on the base member 70 in a thickness direction of the base member 70 in the same manner as the first connector 10A of the above-mentioned embodiment, and two connecting portions 71B and 71C extending in opposite directions from the base portion 71A. In addition, the connecting member 71 has a step portion 76 and a long hole 77 formed as strength reduction portions for reducing the bending strength of the connecting portions 71B and 71C relative to the base portion 71A, and at the tip of the connecting portions 71B and 71C, a cylindrical portion 80 is formed by curling the two divided cylindrical portions 80A divided by a cut portion 81.

The base member 70 has a long hole 85 formed parallel to the two parallel outer edge portions 70A, 70B of the base member 70, and of this long hole 85, which has a component in the thickness direction of the door frame 2, the two parallel inner long side portions 85A, 85B serve as guide portions for guiding the movement of the connecting member 71. For base members 70 arranged on side frame members 2A, 2B of the door frame 2, these inner long side portions 85A, 85B are spaced apart in the length direction of the side frame members 2A, 2B, and for base members 70 arranged on top frame member 2C, they are spaced apart in the length direction of the top frame member 2C.

Figures 23 (A) and (B) show side and front views of connecting member 71, and Figure 24 shows an oblique view of connecting member 71. As shown in these Figures 23 and 24, the base portion 71A of the connecting member 71 has two straddling parts 88 connected to the base portion 23A, which are formed in the center between the two connecting parts 71B, 71C on both sides of the width of the base portion 71A and protrude in the thickness direction of the connecting member 71. As can be seen from Figure 22, when the base portion 71A of the connecting member 71 is placed on the foundation member 70 fixed to the side frame members 2A, 2B and the upper frame member 2C of the door frame 2, these straddling parts 88 straddle the two inner long side parts 85A, 85B of the long hole 85 formed in the base member 70, which is a plate-shaped member, outside these inner long side parts 85A, 85B, i.e., inside the long hole 85. Two slip prevention parts 89 are provided at the tip of each of the two straddling parts 88, protruding in opposite directions.

The protruding direction of these slip prevention parts 89 is the up-down direction, which is perpendicular to the direction of the gap between the side frame members 2A, 2B and the auxiliary member 8 on the core member 5A, 5B side of the wall 4, and the thickness direction of the door frame 2, for the connecting member 71 whose base part 71A is superimposed on the foundation member 70 arranged on the side frame members 2A, 2B of the door frame 2 in the thickness direction of the foundation member 70; and the left-right direction, which is perpendicular to the direction of the gap between the upper frame member 2C and the auxiliary member 8 on the core member 5C side of the wall 4, and the thickness direction of the door frame 2, for the connecting member 71 whose base part 71A is superimposed on the foundation member 70 arranged on the upper frame member 2C in the thickness direction of the foundation member 70.

The foundation members 70 arranged on the side frame members 2A and 2B of the door frame 2 are arranged at an incline in the vertical direction, which is the length direction of the side frame members 2A and 2B, similar to the foundation member 20 in the embodiment described above, and the foundation members 70 arranged on the upper frame member 2C are arranged at an incline in the horizontal direction, which is the length direction of the upper frame member 2C. Therefore, of the four anti-detachment parts 89 provided on the connecting member 71, the two anti-detachment parts 89 arranged diagonally can be moved while being guided by the guide parts of the base member 70 while facing the base member 70 on the back side of the base member 70, thereby obtaining the same effect as the embodiment described above.

The connector of this embodiment described above is a first connector 60A in which two connectors 71B and 71C are provided on a connecting member 71, but the guide portion that guides the movement of the connecting member can also be the inner long side portion of the long hole in a second connector in which a single connecting portion is provided on the connecting member.

The present invention can be used to connect two building materials that are spaced apart.
