Description

[Technical field]

[0001] The present invention relates to a positioning fixture, and in particular to a positioning fixture used for transporting or storing a column member and a brace member connected to the column member at a predetermined inclination angle, with the brace member positioned at an angle smaller than the inclination angle relative to the column member. [Background technology]

[0002] In general, the framework of a bearing wall is composed of column members and brace members. The brace members are connected to the column members at a predetermined inclination angle (see, for example, Patent Document 1). The pillar members and brace members are assembled in advance at a factory, loaded onto a truck, and transported to the construction site. Specifically, at the factory, the pillar members and brace members are connected with permanent bolts or temporary bolts so that the inclination angle of the brace members relative to the pillar members is the same predetermined inclination angle as that at the construction site. Then, in the connected state, the pillar members and brace members are transported to the construction site. The transported pillar members and brace members are unloaded by a tow truck or the like installed at the construction site, and stored at the construction site.

[0003] [Patent Document 1] JP 2014-221980 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, in a factory, a column member and a brace member are connected so that the inclination angle of the brace member with respect to the column member is the same as the inclination angle in the installed state, and then transported or stored to a construction site. However, when the column member and the brace member are connected at the same inclination angle as the construction site, the gap between the column member and the brace member becomes larger, and the width of the truck increases, which may reduce the loading capacity of the truck. In addition, when storing the column member and the brace member at the factory or the construction site, a large storage space is required. Furthermore, if the column members and the brace members are loaded separately onto a truck for transportation or storage, they would have to be assembled separately at the construction site, which could reduce work efficiency.

[0005] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a positioning retainer that can be compactly transported or stored in a state in which a brace member is positioned relative to a column member. [Means for solving the problem]

[0006] The above problem is solved by the positioning fixture of the present invention, which is a positioning fixture used for transporting or storing a pillar member and a brace member connected to the pillar member at a predetermined inclination angle, with the brace member positioned at an angle smaller than the inclination angle relative to the pillar member, and which comprises a first mounting portion attached to a connection portion of the pillar member, a second mounting portion attached to a connected portion of the brace member, and a positioning portion that connects the second mounting portion at an inclination relative to the first mounting portion, and positions the brace member at the angle relative to the pillar member when the first mounting portion is attached to the pillar member and the second mounting portion is attached to the brace member. With the above configuration, the positioning fixture positions and holds the brace member relative to the column member at an angle smaller than the inclination angle at which the brace member is connected at the construction site, so the distance between the column member and the brace member is smaller, allowing for a larger truck load. Also, the space required for storing the column members and brace members at the factory or construction site can be reduced. Furthermore, since the column member and the brace member are transported or stored in a positioned state, there is no need to assemble the column member and the brace member separately at the construction site, improving work efficiency. Also, since the brace member can be transported or stored in a positioned state relative to the column member without using the bolt, damage to the bolt can be suppressed.

[0007] In this case, the first mounting portion is attached to the connecting flange of the column member, and the second mounting portion is attached to the connected flange of the brace member that faces the connection flange, and the positioning portion is inclined relative to the connecting flange to position the connected flange when the first mounting portion is attached to the connecting flange and the second mounting portion is attached to the connected flange. With the above-described configuration, the positioning retainer positions and retains the connected flange of the brace member relative to the connecting flange of the column member, making it possible to easily position the column member and the brace member in a state that is closer to the installed state.

[0008] In this case, the first mounting portion has a first connecting piece facing the connection surface of the connecting flange, and a first clamping piece arranged opposite the first connecting piece and clamping the connection flange together with the first connecting piece, the second mounting portion has a second connecting piece facing the connected surface of the connected flange, and a second clamping piece arranged opposite the second connecting piece and clamping the connected flange together with the second connecting piece, and the positioning portion positions the connected surface by inclining it relative to the connection surface when the first mounting portion clamps the connecting flange and the second mounting portion clamps the connected flange. With the above configuration, the positioning fixture is attached to the column member and the brace member so as to clamp the connecting surface of the column member and the connected surface of the brace member. Therefore, the work of removing the temporary bolt is not required, and the work efficiency is improved. In addition, the positioning fixture can be removed while the column member and the brace member are laid flat, and the work efficiency is improved.

[0009] In this case, the first mounting portion clamps the connecting flange from the side opposite the column body side of the column member, and the second mounting portion clamps the connected flange from the side opposite the column body side of the column member. With the above-mentioned configuration, the positioning fixture can be easily removed from the side while the column member and the brace member are laid flat, improving work efficiency. In addition, with a simple configuration, the column member and the brace member can be lifted by a crane while laid flat.

[0010] In this case, the first mounting portion has a first engaging portion that is inserted into a first insertion hole provided in the connecting flange, the second mounting portion has a second engaging portion that is inserted into a second insertion hole provided in the connected flange, the positioning portion has a first opposing surface that faces the connecting surface of the connecting flange and a second opposing surface that is inclined relative to the first opposing surface and faces the connected surface of the connected flange, and a first engaged portion with which the first engaging portion engages is formed on the first opposing surface, and a second engaged portion with which the second engaging portion engages is formed on the second opposing surface. With the above-mentioned configuration, the column member and the brace member can be firmly connected with a simple configuration. In addition, the positioning fixture can be removed with the column member and the brace member laid flat, improving work efficiency. In addition, the column member and the brace member can be lifted by a crane from the flat state.

[0011] In this case, the first mounting portion has a first threaded portion that is inserted into a first insertion hole provided in the connecting flange, the second mounting portion has a second threaded portion that is inserted into a second insertion hole provided in the connected flange, and the positioning portion has a bent shaft portion that connects the first threaded portion and the second threaded portion. With the above-mentioned configuration, the column members and the brace members can be firmly positioned and held. In addition, the positioning fixtures can be removed while the column members and the brace members are laid flat, improving work efficiency. In addition, the column members and the brace members can be lifted by a crane while laid flat.

[0012] In this case, the first mounting portion has a first slit portion into which the connecting flange is inserted, and the second mounting portion has a second slit portion into which the connected flange is inserted, the first slit portion and the second slit portion are formed at different positions on the outer surface of the positioning retainer and recessed in the same direction from the outer surface of the positioning retainer, and the positioning portion connects the first mounting portion and the second mounting portion so that the second extension direction of the second slit portion is inclined relative to the first extension direction of the first slit portion. With the above-mentioned configuration, the work of removing the temporary bolts is not required, and the work efficiency is improved. Also, the positioning fixture can be removed from the front while the column member and the brace member are laid flat, and the work efficiency is improved. Effect of the Invention

[0013] According to the positioning retainer of the present invention, the brace member can be transported or stored in a compact state while being positioned relative to the column member. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A first embodiment of the present invention will be described below with reference to FIGS. This embodiment relates to a positioning holder that is used to transport or store a column member and a brace member connected to the column member at a predetermined inclination angle, with the brace member positioned at an angle smaller than the inclination angle relative to the column member, and that can compactly transport or store the brace member in a state where it is positioned relative to the column member. In the following description, the "vertical direction" refers to the vertical direction of the column member and the brace member in the installed state where the brace member is connected to the column member, as shown in Figure 1. Also, the "connection direction" refers to the direction in which the brace member is connected diagonally to the column member, as shown in Figure 1. In addition, the "front-rear direction" refers to the front-rear direction when the column member and the brace member are viewed from the front in the installed state in which the brace member is connected to the column member. The "incline direction" refers to the direction perpendicular to the "connection direction" and the "front-rear direction" as shown in Figure 1, and is the direction in which the flange parts of the column member and the brace member are inclined.

[0016] <Overall structure of positioning fixture> The positioning fixture 1 of this embodiment, as shown in Figures 1 and 2, is used when transporting or storing a column member P and a brace member B, which is connected to the column member P at a predetermined inclination angle θ1, in a state in which the brace member B is positioned at an angle θ2 smaller than the inclination angle θ1 relative to the column member P.

[0017] For example, as shown in Fig. 2, the positioning fixture 1 is attached to a pillar member P and a brace member B in a factory. Then, the positioning fixture 1 positions the brace member B at an angle θ2 relative to the pillar member P and holds the pillar member P and the brace member B. The pillar member P and the brace member B, while positioned by the positioning fixture 1, are transported from the factory to a construction site. Then, the positioning fixture 1 is removed from the column member P and the brace member B at the construction site. As shown in Fig. 1, the brace member B is connected to the column member P so as to be at a predetermined inclination angle θ1 with respect to the column member P and constructed.

[0018] <Load-bearing wall> Here, the column members P and brace members B that constitute the load-bearing wall W will be described below. As shown in Fig. 1, the column member P is a steel column that constitutes the skeleton of the bearing wall W. The column member P has a column body P1 in the shape of a square pipe extending in the vertical direction, and a column-side joint P2 integrally joined to the column body P1 by welding. This column-side joint P2 corresponds to the connection part according to the present invention. The column-side joint P2 is a member for connecting to the brace-side joint B2 of the brace member B described later. The column-side joint P2 has a column-side bracket P2a extending downward in the connection direction from the upper end of the column main body P1, and a plate-shaped column-side flange P2b formed at the lower end of the column-side bracket P2a. This column-side flange P2b corresponds to the connection flange according to the present invention.

[0019] As shown in FIG. 4, the pillar-side bracket P2a has a cross-shaped cross section, and is configured so that a first rib P2a1 extending in an oblique direction and a second rib P2a2 extending in the front-rear direction intersect with each other. The column-side flange P2b is a plate-like member that is attached to the lower end of the column-side bracket P2a so as to be inclined relative to the vertical direction, as shown in Fig. 1. The lower surface of the column-side flange P2b becomes a connection surface P2b1 that connects to the brace member B.

[0020] As shown in Fig. 1, the brace member B is a steel column that constitutes the skeleton of the load-bearing wall W. The brace member B has a brace body B1 in the shape of a square pipe and extending obliquely relative to the column member P, a brace side joint B2 integrally joined to the brace body B1 by welding, and a damper B3 formed at the lower end of the brace body B1. This brace side joint B2 is a part that corresponds to the connected part according to the present invention. The brace side joint B2 is a member for connecting to the column side joint P2 of the column member P. The brace side joint B2 has a brace side bracket B2a extending upward in the connection direction from the upper end of the brace main body B1, and a plate-shaped brace side flange B2b formed on the upper end of the brace side bracket B2a. This brace side flange B2b corresponds to the connected flange according to the present invention.

[0021] As shown in FIG. 4, the brace side bracket B2a has a cross-shaped cross section and is configured so that a third rib B2a1 extending in the inclined direction of the brace side flange B2b intersects with a fourth rib B2a2 extending in the front-rear direction. 1, the brace side flange B2b is a plate-shaped member and is attached to the upper end of the brace side bracket B2a so as to be inclined relative to the vertical direction. The upper surface of the brace side flange B2b becomes a connected surface B2b1 that is connected to the column member P. The damper B3 is a member that absorbs energy applied due to an earthquake or the like, and is attached to the lower end of the brace body B1.

[0022] As shown in Fig. 1, the load-bearing wall W is mainly composed of a pair of column members P erected with a predetermined distance between them, and a brace member B connected diagonally between the pair of column members P. The brace member B is connected to one of the column members P by making surface contact between the column side flange P2b of one of the column members P and the brace side flange B2b of the brace member B and fastening them together with fasteners such as bolts and nuts. Then, the damper B3 of the brace member B is attached to the lower end of the other column member P, and the load-bearing wall W is constructed. When the column member P and the brace member B are installed, the brace member B is connected to the column member P at an inclination angle θ1. In other words, the angle between the axis O1 of the column body P1 of the connected column member P and the axis O2 of the brace body B1 of the brace member B is the inclination angle θ1.

[0023] <Positioning holder> 2, the positioning retainer 1 retains the column member P and the brace member B in a state in which the brace member B is positioned at an angle θ2 smaller than the inclination angle θ1 relative to the column member P. In other words, the angle formed by the axis O1 of the column body P1 of the positioned and retained column member P and the axis O2 of the brace body B1 of the brace member B is the angle θ2. The angle θ2 may be any angle as long as it is smaller than the inclination angle θ1 during construction, and may be, for example, 0°.

[0024] As shown in Figures 2 to 6, the positioning retainer 1 is mainly composed of a first mounting portion 2 that is attached to the column side joint P2 of the column member P, a second mounting portion 3 that is attached to the brace side joint B2 of the brace member B, and a positioning portion 4 that positions the brace member B relative to the column member P. The first mounting portion 2 and the second mounting portion 3 have a W-shape in a front view, and are formed, for example, by pressing a metal plate. The positioning portion 4 connects the second mounting portion 3 in a state inclined relative to the first mounting portion 2. When the first mounting portion 2 is attached to the pillar member P and the second mounting portion 3 is attached to the brace member B, the positioning portion 4 positions the brace member B with respect to the pillar member P at an angle θ2 with respect to the pillar member P.

[0025] As shown in Figs. 3 and 4, the first mounting portion 2 has a U-shape in front view, and is a portion to be mounted to the column-side flange P2b of the column-side joint P2. The first mounting portion 2 has a first connection piece 2a facing the connection surface P2b1 of the column side flange P2b, a first clamping piece 2b arranged opposite the first connection piece 2a and clamping the column side flange P2b together with the first connection piece 2a, and a first connecting piece 2c connecting the first connection piece 2a and the first clamping piece 2b.

[0026] The first connection piece 2a is a plate-shaped member and is arranged to face the connection surface P2b1 of the column-side flange P2b. The second connection piece 3a, which will be described later, is connected to the end of the first connection piece 2a on the column main body P1 side in the inclination direction. The first clamping piece 2b is a plate-like member and is arranged to face the flange upper surface P2b2 of the column-side flange P2b. The first clamping piece 2b extends from the first connecting piece 2c toward the column main body P1 in the inclination direction of the first connecting piece 2a. As shown in FIG. 6, a first notch 2d is formed in the center of the first clamping piece 2b in the front-rear direction.

[0027] As shown in Fig. 4 to Fig. 6, the first connection piece 2a and the first clamping piece 2b are connected by the first connecting piece 2c. The first mounting part 2 clamps the column side flange P2b from the side opposite to the column main body P1 of the column member P (the right side in Fig. 5). At this time, the first rib P2a1 of the column side bracket P2a is inserted into the first notch 2d. In addition, the tip of the first clamping piece 2b abuts against the second rib P2a2.

[0028] As shown in Figs. 3 and 4, the second mounting portion 3 has a U-shape in front view, and is a portion to be mounted to the brace-side flange B2b of the brace-side joint B2. The second mounting portion 3 has a second connection piece 3a that faces the connected surface B2b1 of the brace side flange B2b, a second clamping piece 3b that is arranged opposite the second connection piece 3a and clamps the brace side flange B2b together with the second connection piece 3a, and a second connecting piece 3c that connects the second connection piece 3a and the second clamping piece 3b.

[0029] The second connection piece 3a is a plate-shaped member and is arranged to face the connected surface B2b1 of the brace-side flange B2b. The first connection piece 2a is connected to the end of the second connection piece 3a on the column main body P1 side in the inclination direction. The second clamping piece 3b is a plate-like member and is arranged to face the flange lower surface B2b2 of the brace-side flange B2b. The second clamping piece 3b extends from the second connecting piece 3c toward the column main body P1 in the direction in which the second connecting piece 3a is inclined. As shown in Fig. 6, a second cutout portion 3d is formed in the center of the second clamping piece 3b in the front-rear direction.

[0030] As shown in Figures 4 to 6, the second connection piece 3a and the second clamping piece 3b are connected by the second connecting piece 3c. The second mounting portion 3 clamps the brace side flange B2b from the side opposite to the column main body P1 of the column member P (the right side in Figure 5). At this time, the third rib B2a1 of the brace side bracket B2a is inserted into the second cutout portion 3d. In addition, the tip of the second clamping piece 3b abuts against the fourth rib B2a2.

[0031] As shown in Figs. 3 and 4, the positioning portion 4 has a triangular shape in a front view, and is a portion that connects the second mounting portion 3 to the first mounting portion 2 in a tilted state. As shown in FIG. 6, the positioning holder 1 has an H-shape in side view, and the positioning portion 4 is disposed between the first connecting piece 2c and the second connecting piece 3c.

[0032] The positioning portion 4 connects the central portions of the first connection piece 2a and the second connection piece 3a in the front-rear direction. By connecting the central portions, it becomes easier for a worker attaching the positioning fixture 1 to the column member P and the brace member B to grip the positioning portion 4. This allows the worker to easily attach the positioning fixture 1 to the column member P and the brace member B. In addition, the jig body of the positioning fixture 1 can be made lighter. The positioning portion 4 may be configured to connect the entire surfaces of the first connecting piece 2a and the second connecting piece 3a.

[0033] When the first mounting portion 2 is attached to the column side flange P2b and the second mounting portion 3 is attached to the brace side flange B2b, the positioning portion 4 is inclined with respect to the column side flange P2b to position the brace side flange B2b. In detail, when the first connecting piece 2a and the first clamping piece 2b of the first mounting portion 2 clamp the column side flange P2b, and the second connecting piece 3a and the second clamping piece 3b of the second mounting portion 3 clamp the brace side flange B2b, the positioning portion 4 positions the connected surface B2b1 by inclining it relative to the connecting surface P2b1.

[0034] As shown in FIG. 5, the first mounting portion 2 is attached from one side in the inclination direction of the connection surface P2b1 (for example, the side opposite to the column main body P1 side) and clamps the column-side flange P2b. The second mounting portion 3 is attached from one side in the inclined direction of the connected surface B2b1 (for example, the side opposite to the column main body P1 side) to sandwich the brace side flange B2b. That is, the first mounting portion 2 and the second mounting portion 3 are attached from the same side (the right side in FIG. 5).

[0035] The positioning portion 4 connects the first connecting piece 2a and the second connecting piece 3a with the direction in which the second mounting portion 3 clamps the brace side flange B2b (the direction of arrow A2 shown in Figure 5) inclined relative to the direction in which the first mounting portion 2 clamps the column side flange P2b (the direction of arrow A1 shown in Figure 5). The positioning fixture 1 clamps the upper and lower surfaces of the column-side flange P2b with the first mounting portion 2, and clamps the upper and lower surfaces of the brace-side flange B2b with the second mounting portion 3.

[0036] A worker attaches the positioning fixture 1 to the column member P and brace member B that are laid flat, for example, in a factory. Specifically, the worker first attaches the second mounting portion 3 of the positioning fixture 1 from the side to the brace side flange B2b of the brace member B. Then, the worker holds the brace member B and the positioning fixture 1 and attaches the first mounting portion 2 of the positioning fixture 1 to the column side flange P2b of the column member P from the side. In this way, the worker can position the connected surface B2b1 by inclining it relative to the connecting surface P2b1 by attaching the positioning fixture 1 to the pillar member P and the brace member B. Note that the method of attaching the positioning fixture 1 is not limited to this, and for example, it may be attached to the pillar member P and the brace member B placed vertically. Also, the method of attachment is not limited to from the side, and the worker may attach the positioning fixture 1 from the front.

[0037] With the above configuration, when the first mounting portion 2 is attached to the pillar member P and the second mounting portion 3 is attached to the brace member B, the positioning portion 4 positions the brace member B relative to the pillar member P at an angle θ2 relative to the pillar member P. Therefore, the distance D2 (see FIG. 2) between the column member P and the brace member B when the column member P and the brace member B are positioned and held by the positioning part 4 of the positioning holder 1 is smaller than the distance D1 (see FIG. 1) between the column member P and the brace member B when the load-bearing wall W is constructed. This allows the loading capacity of a truck to be increased. Also, the space required for storing the column member P and the brace member B at the factory or construction site can be reduced.

[0038] In addition, since the positioning fixture 1 holds the column member P and the brace member B in a positioned state, there is no need to assemble the column member P and the brace member B separately at the construction site, improving work efficiency. Furthermore, since the column member P and the brace member B are positioned and held without using the bolt, damage to the bolt can be suppressed.

[0039] In addition, since the positioning fixture 1 is attached to the column member P and the brace member B from the side, a worker can easily remove the positioning fixture 1 from the side while the column member P and the brace member B are laid flat. This improves work efficiency. In addition, since the work of removing the temporary bolts is no longer necessary, work efficiency is also improved.

[0040] In addition, the flange portions of the column member P and the brace member B are vertically clamped. Therefore, with a simple configuration, the column member P and the brace member B can be lifted by a crane from a flat-laid state.

[0041] In this embodiment, the positioning retainer 1 is disposed at a portion where the column-side joint P2 of the column member P and the brace-side joint B2 of the brace member B are connected. However, the portions to which the first mounting portion 2 and the second mounting portion 3 are attached are not limited to the column-side flange P2b and the brace-side flange B2b. For example, the site to which the first mounting portion 2 and the second mounting portion 3 are attached may be the column body P1 or the brace body B1. At this time, the positioning retainer 1 is attached to the column member P and the brace member B so that the state in which the brace member B is positioned and held relative to the column member P is close to the installed state of the column member P and the brace member B.

[0042] Second Embodiment Next, a positioning holder 10 according to a second embodiment will be described with reference to Figures 7 and 8. Note that a description of the contents overlapping with the above-mentioned positioning holder 1 will be omitted. The positioning retainer 10 is mainly composed of a first mounting portion 12 that is attached to the column side joint P2 of the column member P, a second mounting portion 13 that is attached to the brace side joint B2 of the brace member B, and a positioning portion 14 that positions the brace member B relative to the column member P.

[0043] 7 and 8, the first mounting portion 12 is, for example, a fixing bolt, which is inserted into a first insertion hole P2b3 formed in the column-side flange P2b. The first mounting portion 12 has an upper male thread portion 12a which is inserted into the first insertion hole P2b3, and an upper bolt head portion 12b. The upper male thread portion 12a corresponds to the first engagement portion according to the present invention. The first insertion hole P2b3 of the column side flange P2b is a hole through which the bolt is inserted during construction.

[0044] 7 and 8, the second mounting portion 13 is, for example, a fixing bolt, which is inserted into a second insertion hole B2b3 formed in the brace side flange B2b. The second mounting portion 13 has a lower male thread portion 13a which is inserted into the second insertion hole B2b3, and a lower bolt head portion 13b. The lower male thread portion 13a corresponds to the second engagement portion according to the present invention. The second insertion hole B2b3 of the brace side flange B2b is a hole through which the bolt is inserted during construction.

[0045] 7 and 8, the positioning portion 14 is, for example, a wedge-shaped metal member and has a triangular shape when viewed from the front. The positioning portion 14 is a portion that connects the second mounting portion 13 to the first mounting portion 12 in an inclined state. The positioning portion 4 has a first opposing surface 14a facing the connection surface P2b1 of the column-side flange P2b and a second opposing surface 14b facing the connected surface B2b1 of the brace-side flange B2b. The second opposing surface 14b is configured to be inclined with respect to the first opposing surface 14a.

[0046] An upper female screw hole 14c into which the upper male screw portion 12a engages is formed on the first opposing surface 14a. The upper female screw hole 14c is formed at a position on the first opposing surface 14a corresponding to the first insertion hole P2b3 of the column side flange P2b. The upper female screw hole 14c is a portion corresponding to the first engaged portion according to the present invention. A lower female screw hole 14d with which the lower male screw portion 13a engages is formed in the second opposing surface 14b. The lower female screw hole 14d is formed at a position on the second opposing surface 14b corresponding to the second insertion hole B2b3 of the brace side flange B2b. The lower female screw hole 14d is a portion corresponding to the second engaged portion according to the present invention.

[0047] The upper male thread portion 12a of the first mounting portion 12 is inserted into the first through-hole P2b3 and screwed into the upper female threaded hole 14c. The lower male thread portion 13a of the second mounting portion 13 is inserted into the second through-hole B2b3 and screwed into the lower female threaded hole 14d. In this way, the positioning fixture 10 clamps and holds the column side flange P2b between the upper bolt head 12b and the first opposing surface 14a, and clamps and holds the brace side flange B2b between the lower bolt head 13b and the second opposing surface 14b.

[0048] As shown in Figure 8, when the upper male threaded portion 12a of the first mounting portion 12 engages with the upper female threaded hole 14c via the column side flange P2b and the lower male threaded portion 13a of the second mounting portion 13 engages with the lower female threaded hole 14d via the brace side flange B2b, the positioning portion 14 tilts the brace side flange B2b relative to the column side flange P2b to position it. The positioning portion 14 has a first engagement direction (the direction of arrow A3 shown in FIG. 8) in which the upper male threaded portion 12a engages with the upper female threaded hole 14c via the column side flange P2b, and a second engagement direction (the direction of arrow A4 shown in FIG. 8) in which the lower male threaded portion 13a engages with the lower female threaded hole 14d via the brace side flange B2b. The positioning portion 14 is configured so that the first opposing surface 14a and the second opposing surface 14b are inclined, and position and hold the column side flange P2b and the brace side flange B2b.

[0049] With the above configuration, when the first mounting portion 12 is attached to the pillar member P and the second mounting portion 13 is attached to the brace member B, the positioning portion 14 positions the brace member B relative to the pillar member P at an angle θ2 relative to the pillar member P. Since the positioning part 14 is fixed in a sandwiched state between the pillar member P and the brace member B by the fixing bolts of the first mounting part 12 and the second mounting part 13, the pillar member P and the brace member B can be firmly connected with a simple configuration. Furthermore, since the positioning fixture 10 can be removed with the pillar member P and the brace member B in a state where they are laid flat, work efficiency is improved. Furthermore, the pillar member P and the brace member B can be lifted by a crane from a state where they are laid flat.

[0050] In the present embodiment, the positioning retainer 10 has a configuration in which the first mounting portion 12 and the second mounting portion 13 serve as fixing bolts and the fixing bolts engage with the female threads of the positioning portion 14, but is not limited thereto. For example, the first mounting portion 12 and the second mounting portion 13 may have female threads and the positioning portion 14 may have a male thread. Furthermore, female threads may be formed on the column-side flange P2b and the brace-side flange B2b. In this case, the upper bolt head 12b and the lower bolt head 13b are not necessary.

[0051] <Third embodiment> Next, a positioning holder 20 according to a third embodiment will be described with reference to Fig. 9. Note that descriptions overlapping with the above-mentioned positioning holders 1 and 10 will be omitted. The positioning retainer 20 is mainly composed of a first mounting portion 22 that is attached to the column side joint P2 of the column member P, a second mounting portion 23 that is attached to the brace side joint B2 of the brace member B, and a positioning portion 24 that positions the brace member B relative to the column member P.

[0052] As shown in FIG. 9, the first mounting portion 22 has a first threaded portion 22a that is inserted into a first insertion hole P2b3 formed in the column-side flange P2b, and an upper nut 22b. The first screw portion 22a is a male screw portion formed on the upper end portion of the positioning portion 24, and is screwed into the upper nut 22b.

[0053] As shown in FIG. 9, the second mounting portion 23 has a second screw portion 23a that is inserted into a second insertion hole B2b3 formed in the brace side flange B2b, and a lower nut 23b. The second screw portion 23a is a male screw portion formed on the lower end portion of the positioning portion 24, and is screwed into the lower nut 23b.

[0054] As shown in FIG. 9, the positioning portion 24 is, for example, a long metal member, and is a portion that connects the second mounting portion 23 to the first mounting portion 22 in an inclined state. The positioning portion 24 has a shaft portion 24a that connects the first screw portion 22a and the second screw portion 23a. The first screw portion 22a is formed on an upper end 24b of the shaft portion 24a. The second screw portion 23a is formed on a lower end 24c of the shaft portion 24a.

[0055] As shown in FIG. 9, the shaft portion 24a has a bent shape, and a first joining direction (the direction of arrow A5 shown in FIG. 9) in which the first screw portion 22a is joined to the column side flange P2b is different from a second joining direction (the direction of arrow A6 shown in FIG. 9) in which the second screw portion is joined to the brace side flange B2b.

[0056] The first screw portion 22a of the first mounting portion 22 is inserted into the first insertion hole P2b3 and screwed into the upper nut 22b. The second screw portion 23a of the second mounting portion 23 is inserted into the second insertion hole B2b3 and screwed into the lower nut 23b. The positioning holder 20 sandwiches and holds the column side flange P2b between the upper nut 22b and the upper end 24b of the shaft portion 24a, and sandwiches and holds the brace side flange B2b between the lower nut 23b and the lower end 24c of the shaft portion 24a.

[0057] The positioning portion 24 tilts the brace side flange B2b relative to the column side flange P2b to position it when the first screw portion 22a, the upper nut 22b, and the upper end 24b of the shaft portion 24a of the first mounting portion 22 engage with the column side flange P2b, and when the second screw portion 23a, the lower nut 23b, and the lower end 24c of the shaft portion 24a engage with the brace side flange B2b.

[0058] With the above configuration, when the first mounting portion 22 is attached to the pillar member P and the second mounting portion 23 is attached to the brace member B, the positioning portion 24 positions the brace member B relative to the pillar member P at an angle θ2 relative to the pillar member P. Since the positioning part 24 is fixed in a state sandwiched between the pillar member P and the brace member B by the screw parts of the first mounting part 22 and the second mounting part 23, the pillar member P and the brace member B can be firmly connected with a simple configuration. Furthermore, since the positioning fixture 10 can be removed with the pillar member P and the brace member B in a state where they are laid flat, work efficiency is improved. Furthermore, the pillar member P and the brace member B can be lifted by a crane from a state where they are laid flat.

[0059] In this embodiment, the positioning retainer 20 has the first mounting portion 12 and the second mounting portion 13 as a screw portion and a nut, and the screw portion and the nut engage with the shaft portion 24a of the positioning portion 24, but is not limited thereto. For example, the first mounting portion 22 and the second mounting portion 23 may be formed with a male screw, and the positioning portion 24 may be formed with a female screw.

[0060] <Fourth embodiment> Next, a positioning holder 30 according to a fourth embodiment will be described with reference to Figures 10 and 11. Note that description of the contents overlapping with the positioning holders 1, 10, and 20 described above will be omitted. The positioning retainer 30 is mainly composed of a first mounting portion 32 attached to the column side joint P2 of the column member P, a second mounting portion 33 attached to the brace side joint B2 of the brace member B, and a positioning portion 34 that positions the brace member B with respect to the column member P. The positioning retainer 30 is, for example, a cubic metal member. However, the shape of the positioning retainer 30 is not limited to this, and it may be columnar or spherical.

[0061] As shown in Figures 10 and 11, the first mounting portion 32 is the upper part of the positioning retainer 30, and has a first slit portion 32a into which the column side flange P2b is inserted, and a first groove portion 32b into which the second rib P2a2 of the column side bracket P2a is inserted. The first slit portion 32a is formed so as to be recessed forward from the back surface 31a of the outer surface 31 of the positioning retainer 30, and extends in an inclined direction. The first groove portion 32b is formed so as to be recessed forward from the rear surface 31a, and extends in a direction perpendicular to the inclination direction and the front-rear direction.

[0062] As shown in Figures 10 and 11, the second mounting portion 33 is the lower part of the positioning retainer 30, and has a second slit portion 33a into which the brace side flange B2b is inserted, and a second groove portion 33b into which the fourth rib B2a2 of the brace side bracket B2a is inserted. The second slit portion 33a is formed so as to be recessed forward from the back surface 31a of the outer surface 31, and extends in a direction inclined relative to the first slit portion 32a. The second groove portion 33b is formed so as to be recessed forward from the rear surface 31a, and extends in a direction inclined with respect to the first slit portion 32a and in a direction perpendicular to the front-rear direction.

[0063] As shown in FIG. 10, the positioning portion 34 has a wedge-shaped protrusion portion formed between the first slit portion 32a and the second slit portion 33a, and connects the first slit portion 32a and the second slit portion 33a on the front surface 31b side of the outer surface 31. The positioning portion 34 connects the first mounting portion 32 and the second mounting portion 33 so that the second extension direction (the direction of arrow A8 shown in Figure 10) in which the second slit portion 33a extends is inclined relative to the first extension direction (the direction of arrow A7 shown in Figure 10) in which the first slit portion 32a extends. The first slit portion 32a and the second slit portion 33a are formed in different positions on the outer surface 31 and recessed in the same direction (that is, recessed forward from the rear surface 31a).

[0064] When the first slit portion 32a is attached to the column side flange P2b and the second slit portion 33a is attached to the brace side flange B2b, the positioning portion 34 inclines the brace side flange B2b relative to the column side flange P2b to position it.

[0065] With the above configuration, when the first mounting portion 32 is attached to the pillar member P and the second mounting portion 33 is attached to the brace member B, the positioning portion 34 positions the brace member B relative to the pillar member P at an angle θ2 relative to the pillar member P. Since the positioning parts 34 are attached to the pillar member P and the brace member B from the front, a worker can easily remove the positioning fixture 1 from the front while the pillar member P and the brace member B are laid flat, improving work efficiency. In addition, since the work of removing the temporary bolts is no longer necessary, work efficiency is improved.

[0066] <Other embodiments> The positioning fixture 1 of the present invention is not limited to the above embodiment. In this embodiment, the case where the brace side joint B2 of the brace member B is positioned and held to the column side joint P2 of the column member P has been described as an example. However, the present invention is not limited to this, and is also suitable for positioning and holding the brace member B to the column member P without using a joint. Moreover, the present invention is not limited to positioning and holding the column member P and the brace member B, but is also suitable for positioning and holding architectural members when one architectural member is attached diagonally to the other architectural member.

[0067] In the above embodiment, the positioning holder according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof. In particular, the above-described embodiment is merely an example and does not limit the present invention. [Explanation of symbols]
