Description

[Technical Field]

[0001] The present invention relates to a hanging hardware and ceiling material support structure that suspends and supports a planar body from a supporting frame of a building. [Background technology]

[0002] BACKGROUND ART In buildings, planar bodies such as ceiling panels are provided so as to extend laterally from supporting frames such as beams, and are supported by being suspended by suspension bolts. For example, Patent Document 1 describes a support hardware that is used by hanging it from the underside of a deck plate, in which a hanging bolt is screwed into a cap nut that is provided with a hanging piece that is hooked onto the reinforcing rib of the deck plate and a fastening piece that fastens the hanging piece. Furthermore, Patent Document 2 describes a configuration for reinforcing a suspended ceiling in which a ceiling lattice frame is supported by suspension bolts via suspension fittings, which includes a suspension fitting mounting section that is attached to the suspension fittings, and a pair of connecting sections that are arranged approximately parallel to the suspension fitting mounting sections, with a ceiling base material fixed to the lower ends of the connecting sections and a brace material fixed to the upper end region. Furthermore, Patent Document 3 describes a configuration in which a suspended ceiling supported by suspension bolts via suspension fittings is reinforced with earthquake-resistant ceiling reinforcing fittings provided at the intersections of ceiling substrate materials.

[0003] In the configurations of Patent Documents 1 to 3, for example, when the support structure is inclined or the planar body is installed at an angle, it is not easy to join the support structure or the planar body to the suspension bolts, and therefore construction is not easy. When installing a planar body by suspending it so that it extends laterally from the supporting structure of a building, it is desirable to be able to carry out the installation easily even if the supporting structure or the planar body is tilted.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 6-44846 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-35942 [Patent Document 3] Japanese Patent Application Laid-Open No. 2014-218808 Summary of the Invention [Problem to be solved by the invention]

[0005] The problem that the present invention aims to solve is to provide a hanging hardware and a ceiling material support structure using hanging hardware that can be easily installed when a planar body is suspended and supported so that it extends horizontally from the supporting structure of a building, even if the supporting structure or planar body is inclined. [Means for solving the problem]

[0006] The inventors focused on the fact that a hanging hardware to be attached to the supporting structure of a building can be constructed by configuring a connecting part that can rotate perpendicular to the supporting structure or the planar body, and a hanging support part that connects to the connecting part, at either or both of the lower end of the supporting structure or the upper end of a planar body placed on the lower side, so that even if the supporting structure or planar body is inclined, it can be easily suspended and supported from the supporting structure, and this led to the invention. In order to solve the above problems, the present invention employs the following means. That is, the hanging hardware of the present invention is a hanging hardware that suspends and supports a planar body so that it extends laterally from a supporting structure of a building, and includes a hanging support part having a hanging bolt that extends in the vertical direction, and a connecting part that is provided at either or both of the upper and lower ends of the hanging support part and connects the hanging support part to the supporting structure when provided at the upper end and the planar body when provided at the lower end, and the connecting part connects a base plate connected to the connecting object and a connecting part that connects the connecting part to the connecting object from opposite end edges of the base plate. a first steel material having a pair of side plates protruding on the opposite side from the object to be connected; a base plate joined to the hanging support part; and a second steel material having a pair of side plates protruding from opposite ends of the base plate towards the object to be connected and arranged to face each of the pair of side plates of the first steel material, wherein an axial member is provided so as to pass through each of the pair of side plates of the first steel material and the second steel material, and when connected to the object to be connected, the rotation angle of the first steel material and the second steel material around the axial member is adjustable. According to the above-mentioned configuration, the hanging hardware includes a hanging support part having a hanging bolt extending in the vertical direction, and a connecting part provided at either or both of the upper and lower ends of the hanging support part, connecting the hanging support part to a support frame when provided at the upper end or to a planar body when provided at the lower end. Here, the connecting part includes a first steel material having a base plate connected to the connecting object and a pair of side plates provided so as to protrude from opposite ends of the base plate toward the connecting object, and a second steel material having a base plate joined to the hanging support part and a pair of side plates protruding from opposite ends of the base plate toward the connecting object and provided so as to face each of the pair of side plates of the first steel material, and a shaft member is provided so as to penetrate each of the pair of side plates of the first steel material and the second steel material, and the rotation angle of the first steel material and the second steel material about the shaft member is adjustable when connected to the connecting object. For this reason, for example, when a planar body is suspended and supported from an inclined support frame, a connecting portion is provided at the upper end of the suspension support portion, and the suspension hardware is then connected to the support frame to be connected. In this case, the first steel member is positioned so that the direction in which the first steel member and the second steel member rotate around the shaft member coincides with the direction in which the support frame is inclined when viewed from above. With the first steel member connected to the support frame, the rotation angle of the first steel member and the second steel member is adjusted, allowing the suspension support portion joined to the second steel member to be suspended vertically downward. Furthermore, when a planar body is suspended and supported in an inclined state by the suspension support portion suspended vertically downward, a connecting portion is provided at the lower end of the suspension support portion, and the suspension hardware is then connected to the planar body to be connected. In this case, the first steel material is positioned so that, when viewed in a plane, the direction in which the first steel material and the second steel material rotate around the shaft member coincides with the direction in which the planar body tilts, and the first steel material is connected to the planar body while adjusting the rotation angle of the first steel material and the second steel material, thereby making it possible to hang the planar body at an angle from the hanging support part. In the structure described above, the inclination of the object to be connected can be accommodated simply by rotating the first steel material connected to the object to be connected and the second steel material joined to the suspension support part appropriately according to the inclination angle of the object to be connected. In this way, a hanging hardware can be provided that can be easily installed when a planar body is suspended from a building's supporting structure so that it extends laterally, even if the supporting structure or the planar body is inclined.

[0007] In one aspect of the present invention, the hanging hardware of the present invention is equipped with an attitude adjustment mechanism that, when the first steel material is connected to the connection object, rotates the first steel material around an axis that is perpendicular to the base plate of the first steel material, thereby enabling adjustment of the attitude of the first steel material relative to the connection object. With this configuration, when the first steel material is connected to the connection object, the posture adjustment mechanism can easily adjust the posture of the first steel material relative to the connection object by rotating the first steel material around an axis that is perpendicular to the base plate of the first steel material.

[0008] In one aspect of the present invention, the ceiling material support structure of the present invention is a ceiling material support structure in which a ceiling material is suspended as a planar body from the support frame of the building using the hanging hardware as described above, and the connecting portion has a diagonal member mounting portion to which a diagonal member is attached, and the diagonal member is provided between the diagonal member mounting portion of the connecting portion provided at the upper end of one of the hanging hardware and the diagonal member mounting portion of the connecting portion provided at the lower end of another of the hanging hardware provided adjacent to the one of the hanging hardware. With this configuration, when horizontal forces due to earthquake loads act on the sheet (ceiling material), the hanging hardware and diagonal members function as horizontal resistance members that suppress the horizontal displacement of the sheet. This suppresses the relative horizontal displacement of the sheet, improving the stability of the sheet. Furthermore, by supporting the sheet using multiple hanging hardware and diagonal members, it is possible to distribute the load across the entire sheet and efficiently transmit horizontal forces. Furthermore, by adjusting the angle and placement of the diagonal members, it is possible to fine-tune the position and inclination of the sheet. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a hanging hardware and a ceiling material support structure using hanging hardware that can be easily installed when a planar body is suspended and supported so that it extends horizontally from the supporting structure of a building, even if the supporting structure or the planar body is inclined.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention provides a hanging hardware for suspending and supporting a sheet-shaped object from a supporting structure of a building. This hanging hardware is composed of a connecting part at either or both of the lower end of the supporting structure and the upper end of the sheet-shaped object placed below, which can rotate perpendicularly to the supporting structure and the sheet-shaped object, and a hanging support part connected to the connecting part. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the accompanying drawings, a description will be given of an embodiment of a hanging hardware and ceiling material support structure according to the present invention. FIG. 1 shows the configuration of a building 1 equipped with a hanging hardware and ceiling material support structure according to an embodiment of the present invention. As shown in Fig. 1, the building 1 includes a plurality of pillars 2, a roof 3, and a ceiling support structure 5. The building 1 has, for example, a rectangular shape in plan view. The shape of the building 1 in plan view may be other shapes, such as a polygonal shape other than a rectangle. The multiple pillars 2 are provided, for example, at the four corners of the building 1. The multiple pillars 2 are provided at predetermined intervals in a first horizontal direction D1 (the left-right direction on the paper in FIG. 1) and in a second horizontal direction D2 (a direction perpendicular to the paper in FIG. 1) perpendicular to the first horizontal direction D1. Each pillar 2 extends upward from a foundation G.

[0012] The roof portion 3 is provided on a plurality of pillars 2. In this embodiment, the roof portion 3 is provided so as to slope diagonally downward from one side (the right side in FIG. 1) to the other side (the left side in FIG. 1) of the horizontal first direction D1. When viewed from above, the slope direction of the roof portion 3 coincides with the horizontal first direction D1. Therefore, the pillar 2R located on one side (the right side in FIG. 1) of the horizontal first direction D1 is longer in the vertical direction Dv than the pillar 2L located on the other side (the left side in FIG. 1) of the horizontal first direction D1. The roof section 3 includes a support structure 30 and a roof material 32. The support structure 30 includes multiple beams 31 and multiple support members 51. The multiple beams 31 are spaced apart in a horizontal second direction D2 (a direction perpendicular to the plane of FIG. 1 ) perpendicular to the horizontal first direction D1. Each beam 31 is made of a steel frame, steel pipes, wood, or the like, and extends in the horizontal first direction D1 when viewed from above. Each beam 31 extends obliquely downward from one side to the other side in the horizontal first direction D1. Each beam 31 is installed between an end beam (not shown) extending in the horizontal second direction D2 between multiple columns 2R and another end beam (not shown) extending in the horizontal second direction D2 between multiple columns 2L. In this way, the support frame 30 is provided at an incline. When viewed from above, the inclination direction of the support frame 30 coincides with the horizontal first direction D1.

[0013] The plurality of support members 51 are supported by the plurality of beams 31. In this embodiment, the support members 51 are steel pipes. For example, the plurality of support members 51 are provided on the plurality of beams 31. The plurality of support members 51 are provided at intervals in the horizontal first direction D1. Each support member 51 extends in the horizontal second direction D2 (lateral direction). Each support member 51 is fixed to the upper surface of the beam 31 that extends obliquely downward from one side to the other side in the horizontal first direction D1. Therefore, as shown in FIG. 1 and FIG. 3, which will be described later, when viewed from the horizontal second direction D2, each support member 51 is provided at an incline in the width direction of the support member 51 following the upper surface of the beam 31. The roof material 32 is provided on a plurality of beams 31. The roof material 32 is formed so as to extend along an inclined surface that slopes obliquely downward from one side to the other side in the first horizontal direction D1. Here, the material and specific configuration of the roof material 32 are not of any importance.

[0014] The ceiling material support structure 5 is provided below the roof material 32. The ceiling material support structure 5 has a configuration in which a sheet body 8 is suspended from a support frame 30 using a hanging hardware 10. The ceiling material support structure 5 includes the sheet body 8 and the hanging hardware 10 that supports the sheet body 8 by suspending it from a support member 51 of the support frame 30. The planar body 8 is a ceiling material. In this embodiment, the planar body 8 is formed so as to extend along an inclined surface that slopes diagonally downward from one side to the other side of the horizontal first direction D1. When viewed from above, the inclination direction of the planar body 8 coincides with the horizontal first direction D1. In this embodiment, the planar body 8 is provided so as to slope in the same direction and at the same angle as the support structure 30. As a result, the planar body 8 is provided parallel to the support structure 30. Here, there is no limitation on the material or specific configuration of the sheet body 8. The sheet body 8 may be formed in a flat plate shape, a lattice shape, or a perforated plate with a plurality of holes formed therein. Furthermore, the sheet body 8 may be stacked in multiple layers one above the other.

[0015] As shown in FIG. 1, the hanging hardware 10 supports the planar body 8 by suspending it from the support member 51 of the support frame 30 so that the planar body 8 extends in the horizontal direction. Fig. 2 is a view of the hanging hardware as seen from a first horizontal direction, and Fig. 3 is a view of the hanging hardware as seen from a second horizontal direction. As shown in Figures 2 and 3, the hanging hardware 10 comprises a hanging support portion 110, an upper connecting portion 120 provided at the upper end of the hanging support portion 110, and a lower connecting portion 130 provided at the lower end of the hanging support portion 110. The suspension support part 110 includes a suspension bolt 111 extending in the up-down direction Dv. The suspension bolt 111 includes a first suspension bolt 112 and a second suspension bolt 113, each having threads in different directions. The first suspension bolt 112 and the second suspension bolt 113 are connected vertically by a turnbuckle 114. The upper end of the first suspension bolt 112 is connected to an upper connecting part 120. The lower end of the first suspension bolt 112 is threaded into a female threaded hole formed in the upper part of the turnbuckle 114. The lower end of the second suspension bolt 113 is connected to a lower connecting part 130. The upper end of the second suspension bolt 113 is threaded into a female threaded hole formed in the lower part of the turnbuckle 114.

[0016] FIG. 4 is an enlarged view of the connecting portion provided at the top of the hanging hardware in FIG. 2 to 4, the upper connecting portion 120 provided at the upper end of the hanging support portion 110 connects the hanging support portion 110 to the support structure 30 as a connection target. More specifically, the connecting portion 120 connects the hanging support portion 110 to the support member 51 of the support structure 30. 4, the upper connecting portion 120 provided at the upper end of the hanging support portion 110 includes a first steel member 121 and a second steel member 122. The first steel member 121 includes a base plate 121a and a pair of side plates 121b. The base plate 121a is connected to the support member 51 of the support framework 30, which is the object of connection, via bolts and nuts 126, bracket fittings 123, and IT hangers 125. 3, the bracket metal fitting 123 has a U-shaped cross section and integrally comprises a base 123a that fits along the underside of the support material 51, and a pair of side portions 123b that rise upward from both sides of the base 123a in the width direction and fit along both side surfaces of the support material 51. As shown in FIG. 4, the base 123a of the bracket metal fitting 123 and the underside portion 51b of the support material 51 are connected by a pair of IT hangers 125.

[0017] The IT hanger 125 includes a shaft 125s extending in the vertical direction Dv and penetrating the base 123a of the bracket member 123 and the underside 51b of the support member 51 from top to bottom; a rotating bar 125r attached to the upper end of the shaft 125s and rotatable about an axis intersecting the central axis of the shaft 125s; and a nut 125b attached to the lower end of the shaft 125s. The shaft 125s of the IT hanger 125 is inserted through a through-hole 51h formed in the underside 51b and a through-hole 123h formed in the base 123a of the bracket member 123. The rotating bar 125r of the IT hanger 125 extends laterally and abuts against the underside 51b from above. This restricts downward movement of the IT hanger 125. In this state, by tightening the nut 125b, the base 123a and the underside 51b are sandwiched between the rotating bar 125r and the nut 125b. In this way, the pair of IT hangers 125 connect the support member 51 and the bracket fitting 123. A locking member 125d is provided on the outside of the nut 125b. In addition to the connection by the pair of IT hangers 125 as described above, as shown in Fig. 3, the bracket fittings 123 are connected to both sides of the support material 51 by screws 129. If the strength is sufficient, the connection by the screws 129 does not have to be performed.

[0018] As shown in FIG. 4, the base plate 121a of the first steel material 121 is disposed along the underside of the base portion 123a of the bracket metal fitting 123. The base plate 121a and the base portion 123a are fastened together by a bolt and nut 126 that passes through the base plate 121a and the base portion 123a in the vertical direction. The bolt and nut 126 includes a bolt 126a, a nut 126b, and a locking device 126c. The head of the bolt 126a is housed in a through-hole 51k formed in the underside portion 51b of the support material 51, and the bolt and nut 126 is not joined to the support material 51. The nut 126b is fastened to the shank of the bolt 126a. A locking device 126c is provided on the outside of the nut 126b. The substrate 121a is formed in a rectangular shape in a plan view. The substrate 121a is provided so that a pair of opposite end sides 121e extend in a horizontal first direction D1 when viewed from above. Since the support material 51 is provided at an incline, the bracket metal fitting 123 joined thereto and the base plate 121a of the first steel material 121 are also in an inclined state. The pair of side plates 121b are provided so as to protrude downward from opposite end edges 121e of the base plate 121a on the side opposite to the support material 51. The pair of side plates 121b are provided so as to be perpendicular to the base plate 121a. The pair of side plates 121b are provided so as to extend within a vertical plane formed by the horizontal first direction D1 and the up-down direction Dv.

[0019] The second steel member 122 includes a base plate 122a and a pair of side plates 122b. A through hole 122h is formed in the base plate 122a. The upper end of the first suspension bolt 112 of the suspension support part 110 is inserted into the through hole 122h. The upper end of the first suspension bolt 112 is joined to the base plate 122a by a pair of nuts 128A, 128B that are provided to sandwich the base plate 122a from above and below. A locking member 128d is provided on the outer side (upper side) of the nut 128A provided on the tip side of the first suspension bolt 112. The substrate 122a is formed in a rectangular shape in a plan view. The substrate 122a is provided so that a pair of end sides 122e located on opposite sides of each other extend in the horizontal first direction D1. The pair of side plates 122b are provided so as to protrude from opposite end edges 122e of the base plate 122a towards the support material 51. The pair of side plates 122b are provided so as to be perpendicular to the base plate 122a. The pair of side plates 122b are provided so as to face each of the pair of side plates 121b of the first steel material 121. In this embodiment, the pair of side plates 121b of the first steel material 121 are inserted between the pair of side plates 122b. The pair of side plates 122b of the second steel material 122 may be configured so as to be inserted between the pair of side plates 121b of the first steel material 121.

[0020] The first steel material 121 and the second steel material 122 are connected via a shaft member 124. The shaft member 124 is provided so as to penetrate through the pair of side plates 121b of the first steel material 121 and the pair of side plates 122b of the second steel material 122. The shaft member 124 includes a pipe member 124a, a shaft bolt 124b, a nut 124c, and a locking device 124d. The pipe member 124a is provided between the pair of side plates 121b. The shaft bolt 124b extends in a direction connecting the pair of side plates 121b and is provided so as to penetrate the pair of side plates 121b, the pair of side plates 122b, and the pipe member 124a. The nut 124c and the locking device 124d are fastened to the tip of the shaft bolt 124b.

[0021] As described above, the first steel material 121 is joined to the bracket fitting 123 with only one bolt and nut 126. For this reason, when performing construction to join the hanging hardware 10 to the support 51, particularly when the first steel material 121 is joined to the supporting structure 30 as the connection target, the first steel material 121 is rotatable about the bolt and nut 126 relative to the bracket fitting 123 and the supporting structure 30. In this way, the connecting portion 120 is formed with an attitude adjustment mechanism 127 as a joining structure using the bolt and nut 126, which allows the first steel material 121 to rotate about an axis C1 along a direction perpendicular to the base plate 121a of the first steel material 121 relative to the supporting structure 30 and the bracket fitting 123 joined to the supporting structure 30, thereby adjusting the attitude of the first steel material 121 relative to the supporting structure 30. Furthermore, when performing construction work to join the hanging hardware 10 to the support material 51, the connecting portion 120 allows the first steel material 121 and the second steel material 122 to rotate relatively around the shaft member 124, and the rotation angle of the first steel material 121 and the second steel material 122 around the shaft member 124 can be adjusted. In this embodiment, as already explained, the roof material 32 is inclined, and accordingly, the support material 51 is also provided at an incline. The first steel material 121 is joined to such a support material 51, and therefore is fixed in an inclined position as shown in FIG.

[0022] Here, in the present embodiment, when the first steel material 121 is connected to the supporting frame 30 as a connection target, the first steel material 121 is joined to the supporting frame 51 in a state in which the first steel material 121 is positioned by the posture adjustment mechanism 127 so that the direction DR1 in which the roof material 32 and the supporting material 51 tilt and the direction DR2 in which the first steel material 121 and the second steel material 122 rotate relatively coincide with each other. In other words, the first steel material 121 is positioned with respect to the supporting frame 51 so that the direction in which the shaft member 124, which is the center of rotation between the first steel material 121 and the second steel material 122, extends is a direction perpendicular to the horizontal first direction D1, which is the tilt direction of the supporting frame 30 when viewed from above, i.e., a horizontal second direction D2. Therefore, when joining the hanging hardware 10 to the support material 51, the rotation angle of the first steel material 121 and the second steel material 122 around the shaft member 124 is adjusted to adjust the rotational posture of the second steel material 122, thereby positioning the second steel material 122 so that the base plate 122a of the second steel material 122 is horizontal, and the hanging support part 110 can be arranged so that the extension direction of the hanging support part 110 joined to the second steel material 122 coincides with the vertical direction.

[0023] After adjusting the rotation angle of the second steel material 122 as described above, the axial bolt 124b of the shaft member 124 may be tightened to the nut 124c, so that the first steel material 121 and the second steel material 122 cannot rotate relatively around the shaft member 124.

[0024] FIG. 5 is an enlarged view of the connecting portion provided at the bottom of the hanging hardware in FIG. As shown in FIGS. 2, 3, and 5, the lower connecting portion 130 provided at the lower end of the hanging support portion 110 connects the hanging support portion 110 to the planar body 8 as the connection target. As shown in FIG. 5, the lower connecting portion 130 provided at the lower end of the hanging support portion 110 includes a first steel member 131 and a second steel member 132. The first steel member 131 includes a base plate 131a and a pair of side plates 131b. The base plate 131a is connected to the planar body 8, which is the connection target, via, for example, a connecting hardware 20. The tip of a connecting bolt 21 of the connecting hardware 20 penetrates the base plate 131a and protrudes upward. A nut 23 is fastened to the tip of the connecting bolt 21, thereby connecting the planar body 8 to the first steel member 131. A locking member 27 is provided on the outside of the nut 23. The substrate 131a is formed in a rectangular shape in a plan view. The substrate 131a is provided so that a pair of opposite end sides 131e extend in a horizontal first direction D1 when viewed from above. Since the planar body 8 is provided at an incline, the base plate 131a of the first steel material 131 joined thereto is also in an inclined state. The pair of side plates 131b are provided so as to protrude upward from opposite end edges 131e of the base plate 131a on the side opposite the planar body 8. The pair of side plates 131b are provided so as to be perpendicular to the base plate 131a. The pair of side plates 131b are provided so as to extend within a vertical plane formed by the horizontal first direction D1 and the up-down direction Dv.

[0025] The second steel member 132 includes a base plate 132a and a pair of side plates 132b. A through hole 132h is formed in the base plate 132a. The lower end of the second suspension bolt 113 of the suspension support part 110 is inserted into the through hole 132h. The lower end of the second suspension bolt 113 is joined to the base plate 132a by a pair of nuts 138A, 138B that are provided to sandwich the base plate 132a from above and below. A locking member 138d is provided on the outer side (lower side) of the nut 138A provided on the tip side of the second suspension bolt 113. The substrate 132a is formed in a rectangular shape in a plan view. The substrate 132a is provided so that a pair of end sides 132e located on opposite sides of each other extend in the horizontal first direction D1. The pair of side plates 132b are provided so as to protrude from opposite end edges 132e of the base plate 132a toward the sheet body 8. The pair of side plates 132b are provided so as to be perpendicular to the base plate 132a. The pair of side plates 132b are provided so as to face each of the pair of side plates 131b of the first steel material 131. In this embodiment, the pair of side plates 131b of the first steel material 131 are inserted between the pair of side plates 132b. The pair of side plates 132b of the second steel material 132 may be configured so as to be inserted between the pair of side plates 131b of the first steel material 131.

[0026] The first steel material 131 and the second steel material 132 are connected via a shaft member 134. The shaft member 134 is provided so as to penetrate through the pair of side plates 131b of the first steel material 131 and the pair of side plates 132b of the second steel material 132. The shaft member 134 includes a pipe member 134a, a shaft bolt 134b, a nut 134c, and a locking device 134d. The pipe member 134a is provided between the pair of side plates 131b. The shaft bolt 134b extends in a direction connecting the pair of side plates 131b and is provided so as to penetrate the pair of side plates 131b, the pair of side plates 132b, and the pipe member 134a. The nut 134c and the locking device 134d are fastened to the tip of the shaft bolt 134b.

[0027] As described above, the first steel material 131 is joined to the sheet body 8 by only one connecting hardware 20. For this reason, when performing construction to join the hanging hardware 10 to the sheet body 8, particularly when the first steel material 131 is connected to the sheet body 8 as the connection target, the first steel material 131 is rotatable relative to the sheet body 8 around the connecting hardware 20. In this way, the connecting portion 130 is formed with an attitude adjustment mechanism 137 as a joining structure using the connecting hardware 20, which allows the first steel material 131 to rotate around the axis C2 along a direction perpendicular to the base plate 131a of the first steel material 131 relative to the sheet body 8, thereby adjusting the attitude of the first steel material 131 relative to the sheet body 8. Furthermore, when performing construction work to join the hanging hardware 10 to the planar body 8, the connecting portion 130 allows the first steel material 131 and the second steel material 132 to rotate relatively around the shaft member 134, and the angle between the first steel material 131 and the second steel material 132 around the shaft member 134 can be adjusted. In this embodiment, the roof material 32 is inclined, and accordingly, the sheet body 8 is also inclined. The first steel material 131 is joined to such a sheet body 8, and therefore is fixed in an inclined position as shown in FIG.

[0028] Here, in this embodiment, when the first steel material 131 is connected to the planar body 8 as a connection target, the first steel material 131 is joined to the planar body 8 in a state in which the first steel material 131 is positioned by the attitude adjustment mechanism 137 so that the direction DR3 in which the planar body 8 tilts and the direction DR4 in which the first steel material 131 and the second steel material 132 rotate relatively coincide with each other. In other words, the first steel material 131 is positioned with respect to the planar body 8 so that the direction in which the shaft member 134, which is the center of rotation between the first steel material 131 and the second steel material 132, extends is a direction perpendicular to the horizontal first direction D1, which is the tilt direction of the planar body 8 when viewed from above, i.e., a horizontal second direction D2. Therefore, when joining the hanging hardware 10 to the planar body 8, the rotation angle of the first steel material 131 and the second steel material 132 around the shaft member 134 is adjusted to adjust the rotational posture of the second steel material 132, thereby positioning the second steel material 132 so that the base plate 132a of the second steel material 132 is horizontal, and the hanging support part 110 can be arranged so that the extension direction of the hanging support part 110 joined to the second steel material 132 coincides with the vertical direction.

[0029] After adjusting the rotation angle of the second steel material 132 as described above, the axial bolt 134b of the shaft member 134 may be tightened to the nut 134c, so that the first steel material 131 and the second steel material 132 cannot rotate relatively around the shaft member 134.

[0030] In this way, the sheet body 8 is suspended and supported by the support material 51 using a plurality of hanging hardware 10. As shown in FIG. 1, adjacent hanging hardware 10 in the horizontal first direction D1 are connected to each other by a diagonal member 200 such as a wire cable. For this reason, as shown in Figures 2 to 5, each hanging hardware 10 is provided with diagonal member mounting portions 141 on the upper and lower connecting portions 120, 130. The diagonal member mounting portions 141 are formed in a circular shape and are provided at both ends of the shaft member 124. The diagonal member mounting portions 141 are fixed to the shaft bolts 124b, 134b of the shaft members 124, 134 so that the shaft bolts 124b, 134b of the shaft members 124, 134 are inserted through the center of the circle. The diagonal member mounting portions 141 are disposed inside U-shaped plates 143 provided on both outer sides of the pair of side plates 122b, 132b. Rings 200r are formed at both ends of the diagonal member 200. The diagonal member 200 is connected to the diagonal member mounting portions 141 by hanging the rings 200r around the outer periphery of the diagonal member mounting portions 141. The diagonal member 200 is stretched between the diagonal member mounting portion 141 of the connecting portion 120 provided at the upper end of one hanging hardware 10 and the diagonal member mounting portion 141 of the connecting portion 130 provided at the lower end of another hanging hardware 10 provided adjacent to the first hanging hardware 10.

[0031] As described above, the diagonal member mounting portion 141 is fixed so that the axial bolts 124b, 134b are inserted therethrough. In this embodiment, the axial bolts 124b, 134b are configured to extend in the horizontal second direction D2, and therefore the diagonal member mounting portion 141 into which they are inserted is provided so as to extend within a plane formed by the horizontal first direction D1 and the up-down direction Dv. Therefore, the diagonal member 200 in this embodiment is provided so as to extend within a plane formed by the horizontal first direction D1 and the up-down direction Dv between adjacent hanging hardware 10 in the horizontal first direction D1.

[0032] Next, we will explain the construction procedure for suspending and supporting a sheet-shaped body from a support structure using hanging hardware. Note that the procedure described below is merely an example, and it goes without saying that the construction order can be changed as appropriate. Fig. 6 is a diagram showing the construction procedure when a planar body is suspended from a support structure using a hanging hardware. Fig. 7 is a diagram showing the construction procedure when a planar body is suspended from a support structure using a hanging hardware, and shows the state following Fig. 6. To suspend and support the planar body 8 from the support framework 30 using the hanging hardware 10 as described above, first, before fixing the bracket metal fitting 123 to the support material 51, the first steel member 121 of the upper connecting portion 120 is temporarily fastened to the bracket metal fitting 123 with the bolt and nut 126. At this time, by leaving the bolt and nut 126 loose and not tightening it, the first steel member 121 becomes rotatable relative to the bracket metal fitting 123 about an axis C1 that is perpendicular to the base plate 121a, making it possible to adjust the posture of the first steel member 121 relative to the bracket metal fitting 123 and the support material 51 of the support framework 30, which is the connection target. In this case, the bolt and nut 126 functions as a posture adjustment mechanism 127 that allows the posture of the first steel member 121 to be adjusted relative to the connection target. Then, as shown in FIG. 6, the bracket metal fitting 123 is positioned so that the base portion 123a is aligned with the lower surface portion 51b of the support material 51 of the support framework 30.

[0033] Next, as shown in FIG. 7, the rotation bar 125r of the IT hanger 125 is extended in the vertical direction Dv along the shaft 125s and inserted from below into the through-holes 123h, 51h formed in the base 123a and the underside 51b of the support member 51. Then, as shown in FIG. 4, the rotation bar 125r is rotated above the base 123a and the underside 51b to extend horizontally, and the rotation bar 125r is abutted against the underside 51b from above. In this state, the nut 125b is tightened, sandwiching the base 123a and the underside 51b between the rotation bar 125r and the nut 125b. In this way, the support member 51 and the bracket member 123 are connected by the pair of IT hangers 125. Furthermore, as shown in FIG. 3, the bracket member 123 is connected to both side surfaces of the support member 51 with screws 129. 3, the first steel member 121 is positioned by the position adjustment mechanism 127 so that the direction DR1 in which the roof material 32 and the support material 51 tilts and the direction DR2 in which the first steel member 121 and the second steel member 122 rotate relatively coincide with each other. Specifically, the first steel member 121 is rotated about the axis C1 so that the extension direction of the shaft member 124 coincides with the second horizontal direction D2. Then, the bolts and nuts 126 are tightened to fix the first steel member 121 to the bracket metal fitting 123 so that the first steel member 121 cannot rotate with respect to the bracket metal fitting 123 and the support material 51.

[0034] Figure 8 shows the construction procedure for suspending and supporting a planar body from a support structure using hanging hardware, and shows the state in which the first steel member of the lower connecting part is attached to the planar body, which is the lower connecting object. 8, the first steel material 131 of the lower connecting portion 130 is temporarily fastened to the sheet-like body 8 by the connecting hardware 20. At this time, by leaving the nut 23 of the connecting hardware 20 loose and not tightened, the first steel material 131 becomes rotatable relative to the sheet-like body 8 around the axis C2 of the connecting bolt 21, which is aligned in a direction perpendicular to the base plate 131a, and the attitude of the first steel material 131 relative to the sheet-like body 8, which is the object to be connected, can be adjusted. 3, the first steel material 131 is positioned by the attitude adjustment mechanism 137 so that the direction DR3 in which the sheet body 8 tilts and the direction DR4 in which the first steel material 131 and the second steel material 132 rotate relatively coincide with each other. Specifically, the first steel material 131 is rotated around the axis C2 so that the extension direction of the shaft member 134 coincides with the horizontal second direction D2. Then, the nut 23 is tightened to fix the first steel material 131 to the sheet body 8 so that the first steel material 131 cannot rotate with respect to the sheet body 8.

[0035] Fig. 9 is a diagram showing the construction procedure when a planar body is suspended from a support frame using a hanging hardware, and shows the state following Fig. 7 and Fig. 8. Fig. 10 is a diagram showing the construction procedure when a planar body is suspended from a support frame using a hanging hardware, and shows the state following Fig. 9. Next, as shown in FIG. 9 , the second steel material 122 is connected to the first steel material 121 of the upper connecting portion 120 with the shaft bolt 124b and nut 124c of the shaft member 124. At this time, it is preferable to attach the hanging support portion 110 and the second steel material 132 of the lower connecting portion 130 to the second steel material 122 in advance. At this time, the rotation angle of the first steel material 121 and the second steel material 122 around the shaft member 124 is adjusted to adjust the rotational position of the second steel material 122, thereby positioning the hanging support portion 110 so that the extension direction of the hanging support portion 110 joined to the second steel material 122 coincides with the vertical direction. After that, the nuts 124c of the shaft members 124 are tightened in all of the hanging hardware 10. Furthermore, the loop 200r of the diagonal member 200 is hooked onto the outer periphery of the diagonal member mounting portion 141 of the upper connecting portion 120.

[0036] Then, as shown in FIG. 10, the planar body 8 and the first steel member 131 of the lower connecting portion 130 are lifted and combined with the second steel member 132 of the lower connecting portion 130 attached to the bottom of the hanging support portion 110. Then, as shown in FIG. 5, the first steel member 131 and the second steel member 132 are temporarily fastened together via the shaft member 134. At this time, by adjusting the rotation angle of the first steel member 131 and the second steel member 132 around the shaft member 134 to adjust the rotational posture of the first steel member 131 and the second steel member 132, it is possible to tilt the planar body 8 by a predetermined angle while maintaining the extension direction of the hanging support portion 110 joined to the second steel member 132 aligned with the vertical direction. After that, the nuts 134c of the shaft members 134 are tightened for all of the hanging hardware 10. Next, the length of the hanging bolt 111 is adjusted by turning the turnbuckle 114 of each hanging hardware 10. After that, the loop 200r of the diagonal member 200 is hung on the diagonal member mounting portion 141 of the connecting portion 130 provided at the lower end of the hanging hardware 10. In this way, the planar body 8 is suspended and supported from the support frame 30 using the hanging hardware 10.

[0037] The hanging hardware 10 described above supports the planar body 8 by suspending it from the support structure 30 of the building 1 so that the planar body 8 extends in the horizontal direction, and includes a hanging support part 110 having a hanging bolt 111 extending in the vertical direction Dv, and connecting parts 120, 130 provided at both the upper and lower ends of the hanging support part 110, connecting the hanging support part 110 to the support structure 30 when provided at the upper end and to the planar body 8 when provided at the lower end, respectively. The connecting parts 120, 130 include base plates 121a, 131a connected to the connecting parts, and a pair of side plates 121b, 131b provided to protrude from opposite end edges 121e, 131e of the base plates 121a, 131a to the opposite side from the connecting parts. , second steel materials 122, 132 each having first steel materials 121, 131 each having a base plate 122a, 132a joined to the hanging support part 110, and a pair of side plates 122b, 132b protruding from opposite end sides 122e, 132e of the base plates 122a, 132a toward the object to be connected and arranged to face each of the pair of side plates 121b, 131b of the first steel materials 121, 131, and shaft members 124, 134 are provided so as to penetrate each of the pair of side plates 121b, 131b, 122b, 132b of the first steel materials 121, 131 and the second steel materials 122, 132, and when connecting to the object to be connected, the rotation angle of the first steel materials 121, 131 and the second steel materials 122, 132 around the shaft members 124, 134 can be adjusted. According to the above-described configuration, the hanging hardware 10 comprises a hanging support portion 110 having a hanging bolt 111 extending in the vertical direction Dv, and connecting portions 120, 130 provided at both the upper and lower ends of the hanging support portion 110, which connect the hanging support portion 110 to the support structure 30 when provided at the upper end and to the planar body 8 when provided at the lower end. Here, the connecting portions 120, 130 are each made up of first steel members 121, 131 each including a base plate 121a, 131a connected to a connection object, a pair of side plates 121b, 131b provided so as to protrude from opposite end sides 121e, 131e of the base plates 121a, 131a to the side opposite the connection object, and base plates 122a, 132a joined to the hanging support portion 110, and a pair of side plates 121b, 131b provided so as to protrude from opposite end sides 122e, 132e of the base plates 122a, 132a to the connection object. and second steel members 122, 132 each having a pair of side plates 122b, 132b arranged to face each of the pair of side plates 121b, 131b, and shaft members 124, 134 are provided so as to penetrate each of the pair of side plates 121b, 131b, 122b, 132b of the first steel members 121, 131 and the second steel members 122, 132, and when connecting to a connection target, the rotation angles of the first steel members 121, 131 and the second steel members 122, 132 about the shaft members 124, 134 are adjustable. Therefore, for example, when supporting a planar body 8 by suspending it from an inclined support frame 30, a connecting portion 120 is provided at the upper end of the hanging support portion 110, and the hanging hardware 10 is then connected to the support frame 30 to be connected. In this case, the first steel material 121 is positioned so that the direction DR2 in which the first steel material 121 and the second steel material 122 rotate about the shaft member 124 coincides with the direction DR1 in which the support frame 30 tilts when viewed from above, and the rotation angle of the first steel material 121 and the second steel material 122 is adjusted while the first steel material 121 is connected to the support frame 30, thereby making it possible to make the hanging support part 110 joined to the second steel material 122 hang vertically downward. Furthermore, when the planar body 8 is to be suspended and supported in an inclined state by the hanging support part 110 hung vertically downward, a connecting part 130 is provided at the lower end of the hanging support part 110, and the hanging hardware 10 is then connected to the planar body 8 to be connected.In this case, the first steel material 131 is positioned so that, when viewed in a plane, the direction DR4 in which the first steel material 131 and the second steel material 132 rotate around the shaft member 134 coincides with the direction DR3 in which the planar body 8 tilts, and the first steel material 131 is connected to the planar body 8 while adjusting the rotation angle of the first steel material 131 and the second steel material 132, thereby making it possible to hang the planar body 8 at an angle from the hanging support part 110. In the above structure, the inclination of the connected object can be accommodated simply by rotating the first steel material 121, 131 connected to the connected object and the second steel material 122, 132 joined to the hanging support part 110 appropriately according to the inclination angle of the connected object. In this way, a hanging hardware 10 can be provided that can be easily installed when the planar body 8 is suspended and supported so as to extend laterally from the support frame 30 of the building 1, even if the support frame 30 or the planar body 8 is inclined.

[0038] In addition, the hanging hardware 10 is equipped with posture adjustment mechanisms 127, 137 that, when the first steel materials 121, 131 are connected to the connection object, rotate the first steel materials 121, 131 around axes C1, C2 that are aligned in a direction perpendicular to the base plates 121a, 131a of the first steel materials 121, 131, thereby enabling adjustment of the posture of the first steel materials 121, 131 relative to the connection object. With this configuration, when the first steel materials 121, 131 are connected to the connection object, the posture adjustment mechanisms 127, 137 rotate the first steel materials 121, 131 around axes C1, C2 that are perpendicular to the base plates 121a, 131a of the first steel materials 121, 131, thereby easily adjusting the posture of the first steel materials 121, 131 relative to the connection object.

[0039] In addition, the connecting portions 120 and 130 are provided with a circularly formed diagonal member mounting portion 141, which is fixed to the axial bolts 124b and 134b of the axial members 124 and 134 so that the axial bolts 124b and 134b of the axial members 124 and 134 are inserted through the center of the circle, and the diagonal member 200, which has a ring 200r formed at its tip, is connected to the diagonal member mounting portion 141 by hanging the ring 200r on the outer periphery of the diagonal member mounting portion 141. According to this configuration, by providing the diagonal member 200 between the diagonal member mounting portion 141 provided at the upper end of one hanging hardware 10 and the diagonal member mounting portion 141 provided at the lower end of another hanging hardware 10 provided adjacent to the first hanging hardware 10, when a horizontal force due to a horizontal load acts on the planar body 8, the hanging hardware 10 and the diagonal member 200 function as horizontal resistance members that suppress horizontal displacement of the planar body 8. This makes it possible to suppress the relative horizontal displacement of the planar body 8 and improve the stability of the planar body 8. Furthermore, by hanging the loop 200r formed at the tip of the diagonal member 200 on the outer periphery of the circularly formed diagonal member mounting portion 141, the diagonal member 200 and the hanging hardware 10 are connected, so that the angle of the diagonal member 200 relative to the hanging hardware 10 can be easily adjusted. This makes it possible to easily install the diagonal member 200.

[0040] The suspension bolt 111 also includes a first suspension bolt 112 and a second suspension bolt 113, each having threads in different directions, and a turnbuckle 114 that connects the first suspension bolt 112 and the second suspension bolt 113. According to this configuration, by rotating the turnbuckle 114 around the central axes of the first suspension bolt 112 and the second suspension bolt 113, the length of the suspension bolt 111 in the up-down direction Dv can be easily adjusted. This allows the length of the hanging bolt 111 to be adjusted to adjust for construction errors.

[0041] Furthermore, the ceiling material support structure 5 as described above is a ceiling material support structure 5 in which the ceiling material is suspended and supported as a planar body 8 from the support frame 30 of the building 1 using the hanging hardware 10 as described above, and the connecting parts 120, 130 are provided with diagonal member mounting parts 141 to which the diagonal member 200 is attached, and the diagonal member 200 is provided between the diagonal member mounting part 141 of the connecting part 120 provided at the upper end of one hanging hardware 10 and the diagonal member mounting part 141 of the connecting part 130 provided at the lower end of another hanging hardware 10 provided adjacent to the one hanging hardware 10. With this configuration, when a horizontal force due to a horizontal load acts on the sheet body 8 (ceiling material), the hanging hardware 10 and the diagonal members 200 function as horizontal resistance members that suppress horizontal displacement of the sheet body 8. This suppresses the relative horizontal displacement of the sheet body 8, improving the stability of the sheet body 8. Furthermore, by supporting the sheet body 8 using multiple hanging hardware 10 and diagonal members 200, it is possible to distribute the load across the entire sheet body 8 and efficiently transmit horizontal forces. Furthermore, by adjusting the angle and arrangement of the diagonal members 200, it is possible to fine-tune the position and inclination of the sheet body 8.

[0042] (Modification of the embodiment) The hanging hardware and ceiling material support structure of the present invention are not limited to the above-described embodiment explained with reference to the drawings, and various modifications are possible within the technical scope. Fig. 11 is a diagram showing a configuration in which adjacent hanging hardware in the horizontal second direction D2 are connected by a diagonal member in a modified embodiment of the present invention. Fig. 12 is a diagram showing the hanging hardware used in the ceiling material support structure according to the modified embodiment of the present invention, viewed from the horizontal second direction. Fig. 13 is a diagram showing the hanging hardware used in the ceiling material support structure according to the modified embodiment of the present invention, viewed from the horizontal first direction. As explained in the above embodiment, the diagonal member 200 in the above embodiment is arranged to extend within a plane formed by the horizontal first direction D1 and the vertical direction Dv. In this modified example, in addition to the configuration of the above embodiment, as shown in FIG. 11, the diagonal member 200 is also arranged within a plane formed by the horizontal second direction D2 and the vertical direction Dv. For this reason, the ceiling material support structure of this modified example uses a first hanging hardware and a second hanging hardware. The first hanging hardware is the hanging hardware 10 of the above embodiment, and therefore its description will be omitted hereinafter. The first hanging hardware is arranged in the same manner as the hanging hardware 10 of the above embodiment.

[0043] As shown in Figures 12 and 13, the second hanging hardware 300 comprises a hanging support part 110, an upper connecting part 320 provided at the upper end of the hanging support part 110, and a lower connecting part 330 provided at the lower end of the hanging support part 110. The upper connecting part 320 provided at the upper end of the hanging support part 110 comprises a first steel member 321, a second steel member 122, and an axial member 124. The lower connecting part 330 provided at the lower end of the hanging support part 110 comprises a first steel member 331, a second steel member 132, and an axial member 134. The second hanging hardware 300 differs from the first hanging hardware 10 only in the configuration of the first steel members 321 and 331; the other members of the connecting parts 320 and 330 and the structure of the hanging support part 110 are the same. Therefore, in the following, the configuration of the first steel members 321 and 331 will be mainly described.

[0044] In the upper connecting portion 320 provided at the upper end of the hanging support portion 110, the first steel member 321 has a base plate 321a and a pair of side plates 321b. The base plate 321a is connected to the support member 51 of the support framework 30, which is the connection target, via a bracket metal fitting 123, an IT hanger 125, and bolts and nuts 126. The base plate 321a of the first steel member 321 is placed along the underside of the base portion 123a of the bracket metal fitting 123. The base plate 321a and the base portion 123a are fastened together by bolts and nuts 126 that pass through the base plate 321a and the base portion 123a in the vertical direction. The substrate 321a is formed in a rectangular shape in a plan view. The substrate 321a is provided so that a pair of opposite end sides 321e extend in the second horizontal direction D2. Since the support member 51 is provided at an angle, the bracket metal fitting 123 joined thereto and the base plate 321a of the first steel member 321 are also in an angled state. The pair of side plates 321b are provided so as to protrude downward from opposite end edges 321e of the base plate 321a on the side opposite the support member 51. The pair of side plates 321b are provided at an angle corresponding to the inclination angle of the support member 51, which is provided at an angle with respect to the base plate 321a. As a result, the pair of side plates 321b are provided so as to be parallel to each other. With the above-described configuration, the first steel member 321 is provided so that the pair of side plates 321b extend in a vertical plane formed by the second horizontal direction D2 and the up-down direction DV.

[0045] In the lower connecting portion 330 provided at the lower end of the hanging support portion 110, the first steel member 331 includes a base plate 331a and a pair of side plates 331b. The base plate 331a is connected to the planar body 8, which is the connection target, via a connecting metal piece 20. The base plate 331a of the first steel member 331 is disposed along the sheet-like body 8. The base plate 331a is joined to the sheet-like body 8 by a connecting metal fitting 20. The substrate 331a is formed in a rectangular shape in a plan view. The substrate 331a is provided so that a pair of opposite end sides 331e extend in the second horizontal direction D2. Since the planar body 8 is provided at an incline, the base plate 331a of the first steel material 331 joined thereto is also in an inclined state. The pair of side plates 331b are provided so as to protrude upward from opposite end edges 331e of the base plate 331a on the side opposite the planar body 8. The pair of side plates 331b are provided at an angle corresponding to the inclination angle of the planar body 8, which is provided at an inclination relative to the base plate 331a. As a result, the pair of side plates 331b are provided so as to be parallel to each other. With the above-mentioned configuration, the first steel member 331 is provided so that the pair of side plates 331b extend in a vertical plane formed by the second horizontal direction D2 and the up-down direction DV.

[0046] In the connecting portions 320, 330, by configuring the first steel members 321, 331 as described above, the shaft members 124, 134 are provided so as to extend in the horizontal first direction D1, perpendicular to the side plates 321b, 331b of the first steel members 321, 331. Therefore, the diagonal member mounting portions 141 inserted into the shaft members 124, 134 are provided so as to extend within a plane formed by the horizontal second direction D2 and the up-down direction Dv, which are perpendicular to the shaft members 124, 134. Therefore, by using the second hanging hardware 300 described as this modified example and providing the diagonal members 200 between adjacent second hanging hardware 300 in the horizontal second direction D2, it is possible to configure the diagonal members 200 to extend within the plane formed by the horizontal second direction D2 and the up-down direction Dv.

[0047] (Other variations) In addition, in the above embodiment, the diagonal member mounting portions 141 are provided on both outer sides of the pair of side plates 122b, 132b of the second steel members 122, 132, but this is not limited to this. The diagonal member mounting portions 141 may be provided on the inner side of the pair of side plates 121b, 131b of the first steel members 121, 131. Alternatively, the diagonal member mounting portions 141 may be provided between the pair of side plates 121b, 131b of the first steel members 121, 131 and the pair of side plates 122b, 132b of the second steel members 122, 132.

[0048] Furthermore, in the above embodiment, the diagonal member 200 is provided, but the diagonal member 200 may be omitted. Furthermore, in this case, even after being connected to the object to be connected, i.e., after installation, the nuts 124c, 134c of the shaft members 124, 134 may not be tightened, and the first steel members 121, 131 and the second steel members 122, 132 may be allowed to rotate freely relative to each other around the shaft members 124, 134. In this case, when the wooden frame is horizontally deformed due to an earthquake or the like, the first steel members 121, 131 and the second steel members 122, 132 rotate relative to each other, and can easily follow this deformation.

[0049] In addition, in the above embodiment, the planar body 8 is provided inclined in the same direction as the support structure 30 at the same angle, but this is not limited to this. The planar body 8 may be provided inclined in a different direction from the support structure 30 at a different angle. As already explained, at the connecting part 120 provided at the upper end of the hanging support part 110, the first steel material 121 is positioned by the posture adjustment mechanism 127 so that the direction DR1 in which the roof material 32 and the support material 51 tilts and the direction DR2 in which the first steel material 121 and the second steel material 122 rotate relatively coincide with each other. Also, at the connecting part 130 provided at the lower end of the hanging support part 110, the first steel material 131 is positioned by the posture adjustment mechanism 137 so that the direction DR3 in which the planar body 8 tilts and the direction DR4 in which the first steel material 131 and the second steel material 132 rotate relatively coincide with each other. Therefore, when the support structure 30 and the planar body 8 are arranged inclined in different directions and at different angles, the shaft member 124 of the connecting portion 120 arranged at the upper end of the hanging support portion 110 and the shaft member 134 of the connecting portion 130 arranged at the lower end of the hanging support portion 110 will be arranged to extend in different directions when viewed from above. Alternatively, the support structure 30 and the planar body 8 may be divided into a plurality of regions, each of which may extend in a different direction or at a different angle.

[0050] In addition, in the above embodiment, the connecting portions 120, 130, which are composed of the first steel members 121, 131 and the second steel members 122, 132, are provided at both the upper and lower ends of the hanging support portion 110, but this is not limited to this. For example, when the planar body 8 is provided under an inclined support structure 30 so as to follow a horizontal plane, i.e., without being inclined, the above-mentioned connecting portion only needs to be provided at the upper end of the hanging support portion 110. That is, the hanging hardware in this case is a hanging hardware that suspends and supports the planar body 8 so as to extend in the horizontal direction from the support framework 30 of the building 1, and includes a hanging support part 110 having a hanging bolt 111 that is provided extending in the vertical direction Dv, and a connecting part 120 that is provided at the upper end of the hanging support part 110 and connects the hanging support part 110 to the support framework 30 as a connection object, and the connecting part 120 includes a base plate 121a connected to the connection object, and a pair of side plates 121b that are provided so as to protrude from opposite end edges 121e of the base plate 121a to the opposite side from the connection object. , a base plate 122a joined to the hanging support part 110, and a second steel material 122 having a pair of side plates 122b protruding from opposite end edges 122e of the base plate 122a toward the object to be connected and arranged to face each of the pair of side plates 121b of the first steel material 121, and an axial member 124 is provided so as to pass through each of the pair of side plates 121b, 122b of the first steel material 121 and the second steel material 122, and when connecting to the object to be connected, the rotation angle of the first steel material 121 and the second steel material 122 around the axial member 124 can be adjusted. In such a case, the suspension bolt 111 and the planar body 8 are arranged perpendicular to each other at the lower end of the suspension support part 110, and therefore can be joined using a known structure. Alternatively, a connecting part 130 may be provided at the lower end of the suspension support part 110 as in the above embodiment, and the rotation angles of the first steel material 131 and the second steel material 132 may be adjusted so that the base plate 131a of the first steel material 131 and the base plate 132a of the second steel material 132 are arranged parallel to each other at positions opposite each other across the shaft member 134. In this state, the base plate 131a of the first steel material 131 is arranged extending in a horizontal plane, and therefore, by joining the planar body 8 to this, the planar body 8 can be arranged along the horizontal plane, i.e., without being inclined.

[0051] Conversely to the above, when the planar body 8 is inclined below the support structure 30 that is installed along a horizontal plane, i.e., without inclination, the connecting portion as described above only needs to be installed at the lower end of the hanging support portion 110. That is, the hanging hardware in this case is a hanging hardware that suspends and supports the planar body 8 so that it extends laterally from the support frame 30 of the building 1, and includes a hanging support part 110 having a hanging bolt 111 that extends in the vertical direction Dv, and a connecting part 130 that is provided at the lower end of the hanging support part 110 and connects the hanging support part 110 to the planar body 8 as the connection object, and the connecting part 130 includes a base plate 131a connected to the connection object, and a pair of side plates 131b that are provided so as to protrude from opposite end edges 131e of the base plate 131a to the opposite side from the connection object, the first steel material 131 having the above-mentioned configuration, a base plate 132a joined to the hanging support part 110, and a second steel material 132 having a pair of side plates 132b protruding from opposite end edges 132e of the base plate 132a towards the object to be connected and arranged to face each of the pair of side plates 131b of the first steel material 131, and an axial member 134 is provided so as to pass through each of the pair of side plates 131b, 132b of the first steel material 131 and the second steel material 132, and when connecting to the object to be connected, the rotation angle of the first steel material 131 and the second steel material 132 around the axial member 134 can be adjusted. In such a case, the suspension bolt 111 and the support frame 30 are arranged perpendicular to each other at the upper end of the suspension support part 110, and therefore can be joined using a known structure. Alternatively, a connecting part 120 may be provided at the upper end of the suspension support part 110 as in the above embodiment, and the rotation angles of the first steel material 121 and the second steel material 122 may be adjusted so that the base plate 121a of the first steel material 121 and the base plate 122a of the second steel material 122 are arranged parallel to each other at positions opposite each other across the shaft member 124. In this state, the base plate 121a of the first steel material 121 is arranged extending within a horizontal plane, and therefore the first steel material 121 can be joined to the support frame 30 arranged along the horizontal plane, i.e., without tilting.

[0052] In addition, the configurations given in the above embodiments can be selected or changed as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
