[0009] The present disclosure relates to a fastening bracket for a seam-seamed roof for fastening a member to be fastened onto a seam-seamed roof, the fastening bracket comprising: a main body, a bolt protruding upward through a hole provided in the main body, and a clamp having a hole for passing the bolt and held by the threaded portion of the bolt; the main body comprises a base on which the member to be fastened can be placed, a first-side gripping portion, and a second-side gripping portion facing the first-side gripping portion; the base comprises a first side edge, a second side edge, or both, of which have spacers protruding upward for positioning the member to be fastened; the first side gripping portion and the second side gripping portion are configured to grip the seam of the seam-seamed roof by tightening a first nut arranged on the threaded portion of the bolt protruding on the base portion; and the clamp is configured to fasten the member to be fastened, positioned and placed by the spacer, between the base and the fastener;
[0010] The disclosed fixing bracket for seam-type roofs (hereinafter also referred to as this bracket) has a simple mounting structure, making it possible to manufacture it at low cost, and it is easy to position and fix fixed components such as solar panels onto seam-type roofs, making it highly workable.
[0011] This metal fitting can be used to fasten solar panels, pipes, heat insulation boards, etc. The seam-type roof to which the fastened member is fastened using this metal fitting is preferably a seam-type metal folded-plate roof.
[0012] 1 to 3 show a front view, a side view, and a perspective view of the metal fitting 100. The metal fitting 100 has a main body 10, a bolt 20 that protrudes upward through a hole provided in the main body 10, and a clamp 30 that has a hole through which the bolt 20 passes and is held by the threaded portion 21 of the bolt 20.
[0013] The main body 10 includes a base 40 on which a member to be fixed can be placed, a first-side grip 50, and a second-side grip 60 facing the first-side grip 50. Either the first-side grip 50 or the second-side grip 60 is integral with the base 40, while the other can be rotatably connected to the base 40. "Integrated" means that they are molded as a single unit, or that they are formed as a single unit by welding or the like. "Rotably connected" means that they are rotatably connected in a direction from the first-side grip 50 to the second-side grip 60, or from the second-side grip 60 to the first-side grip 50, or in both directions.
[0014] The base 40 is provided with upwardly protruding spacers 43 on the first side edge 41, the second side edge 42, or both, for positioning the member to be fixed. The spacers 43 improve workability by facilitating positioning and fixing when fixing the member to the seam roof. The spacers 43 preferably have a width 431 of 1 to 4 cm, and more preferably 2 to 3 cm. The members to be fixed, such as solar panels, pipes, and insulation boards, placed on the seam roof may thermally expand and interfere with adjacent members to be fixed, but by placing the spacers 43 at a predetermined interval, this interference can be prevented.
[0015] FIG. 5 shows a top view of an example of a fixed member 3 placed on a seam 2 on a seam-shaped roof 1 using the spacer 43 of this hardware. The seam 2 located on the back side of the fixed member 3 is indicated by a dashed line. FIG. 6 shows a photograph of an example of an embodiment in which the fixed member 3, a solar panel, is positioned and placed using the spacer 43, with the base of the seam 2 sandwiched between the first hook 51 and the second hook 61 of this hardware 100. The fixed member 3 can be positioned so that its longitudinal direction is perpendicular to the seams 2 and that it spans two or more seams 2 to ensure fixed locations. Therefore, as shown schematically in FIGS. 1 to 3 and 5, the width of the spacer 43 can be positioned perpendicular to the longitudinal direction of the fixed member 3 to ensure the width between the fixed members 3 in the direction perpendicular to the longitudinal direction of the fixed members 3 (parallel to the seams 2).
[0016] The metal fittings 100 are arranged one on each of at least two seams spanning one longitudinal side of the workpiece, and the spacers 43 on each of the at least two metal fittings 100 can position one longitudinal side of the workpiece. Therefore, the workpiece can be positioned using at least two metal fittings 100, each having a spacer 43 provided at either the first side edge 41 or the second side edge 42. By providing the spacer 43 at either the first side edge 41 or the second side edge 42, the workpiece can be positioned more easily and accurately than when spacers 43 are provided at both the first side edge 41 and the second side edge 42. Furthermore, since it is only necessary to provide the spacer 43 at either the first side edge 41 or the second side edge 42, processing costs and material costs are also lower.
[0017] The bolt 20 is inserted through a hole provided through the upper step portion 63 of the second side gripping portion 60 and through an elongated hole provided through the base portion 40 of the first side gripping portion 50 in the direction from the first side to the second side.
[0018] The first-side gripping portion 50 and the second-side gripping portion 60 are configured to grip the seam by tightening a first nut 70 disposed on the threaded portion 21 that protrudes above the base portion 40 of the bolt 20. In the example shown in Fig. 1, tightening the first nut 70 fixes the base portion 40 integrated with the first-side gripping portion 50 and the upper step portion 63 of the second-side gripping portion 60 between the head 22 of the bolt 20, thereby making it possible to clamp the base of the seam between the first claw piece 51 and the second claw piece 61.
[0019] The clamp 30 is configured to fix the fixed member positioned and placed by the spacer 43 between the base portion 40 and the second nut 80 arranged on the threaded portion 21 protruding above the base portion 40 of the bolt 20 by tightening the second nut 80 arranged on the threaded portion 21 protruding above the base portion 40.
[0020] In the example shown in Figures 1 and 2, by tightening the second nut 80, the fixed member positioned and placed by the spacer 43 can be fixed between the holding portion 32 of the clamp 30 and the base portion 40.
[0021] Clamp 30 has a hole through which threaded portion 21 passes and is rotatable around threaded portion 21. Clamp 30 has a U-shaped central portion 31 and a retaining portion 32. When clamp 30 is fixing a fixed member between itself and base portion 40, its cross section is omega-shaped when viewed from first-side gripping portion 50 toward second-side gripping portion 60.
[0022] The clamp 30 has a retaining portion 32 on one or both sides of the central portion 31. Figures 1 to 3 are schematic diagrams of the present fitting including a clamp 30 having retaining portions 32 on both sides of the central portion 31, and Figure 4 is a schematic diagram of the present fitting including a clamp 30 having retaining portion 32 on one side of the central portion 31. The present fitting 100 can be used to secure multiple members to be fastened. When the present fitting 100 is placed on the outer periphery (edge) of multiple members to be fastened, the members to be fastened are located on one side of the present fitting 100, so it is sufficient for the clamp 30 to have a retaining portion 32 on one side. When the present fitting 100 is placed inside (between) multiple members to be fastened, the members to be fastened are located on both sides of the present fitting 100, so it is sufficient for the clamp 30 to have a retaining portion 32 on both sides.
[0023] The width 311 of the center portion 31 of the clamp 30 can be approximately the same as the width 431 of the spacer 43. By making the width 311 approximately the same as the width 431, the member to be fixed can be fixed more stably. The width 321 of the pressing portion 32 of the clamp 30 is not particularly limited as long as it can fix the member to be fixed, but can be, for example, 0.5 to 2 cm, 0.6 to 1.6 cm, or 0.7 to 1.3 cm. The longitudinal direction of the clamp 30 is not particularly limited as long as it can fix the member to be fixed, but can be, for example, 2 to 10 cm, 3 to 8 cm, or 4 to 6 cm.
[0024] The lower surface of the pressing portion 32 of the clamp 30 has an uneven surface as shown in Fig. 2. By having an uneven lower surface of the pressing portion 32, the member to be fixed can be fixed more stably.
[0025] The head 22 of the bolt 20 can be held by a head holder 64 having a barb 641 provided on the upper section 63 of the second gripping section 60. The barb 641 prevents the bolt 20 from falling off the head holder 64, improving workability during installation. The barb 641 also determines the height of the bolt 20. The bolt 20 can be positioned so that it is held by the head holder 64 by pushing it in.
[0026] Preferably, the first and second gripping portions 50, 60 have legs 52, 62 at their respective lower edges. By providing legs 52, 62 at their lower edges, the fitting 100 can be easily positioned approximately horizontally on a seam-type roof during installation, improving installation efficiency.
[0027] Preferably, the first gripping portion 50 includes a first claw 51 extending downward from a lower portion of the first side edge 41 of the base 40 and having a tip at the lower edge directed toward the second side, the second gripping portion 60 includes a terraced portion including an upper step 63 detachable from the base 40 and a lower step having a protruding piece 65, and a second claw 61 extending from the lower edge of the lower step and having a tip at the lower edge directed toward the first side and facing the first claw 51, and the base 40 includes a rotatable receiving portion 44 at a lower portion of the second side edge 42 of the base 40 that rotatably receives the protruding piece 65. The rotatable receiving portion 44 is formed continuously with the base 40 and may be molded integrally with the base 40 or may be welded to the base 40.
[0028] The base 40 may have a protruding piece at the bottom of the second side edge 42 of the base 40, and the second side grip 60 may have a terraced portion including an upper step 63 that is detachable from the base 40 and a lower step having a rotatable receiving portion that rotatably receives the protruding piece. However, an embodiment in which the base 40 has a rotatable receiving portion 44 at the bottom of the second side edge 42 of the base 40 is preferred in that the joining area between the rotatable receiving portion 44 and the base 40 is large and the strength is improved, thereby ensuring sufficient strength even when the main body 10 is made of aluminum.
[0029] The protruding piece 65 preferably has a spherical tip portion having an outer diameter substantially the same as the inner diameter of the rotatable receiving portion 44 as shown in Fig. 1. By having the protruding piece 65 have a spherical tip portion having an outer diameter substantially the same as the inner diameter of the rotatable receiving portion 44, the protruding piece 65 is rotatably held by the rotatable receiving portion 44, and the fulcrum for the rotational movement of the second-side gripping portion 60 can be made more stable.
[0030] Preferably, the rotatable receiving portion 44 has an inner circumference of more than half the circumference. By having the rotatable receiving portion 44 have an inner circumference of more than half the circumference, it is possible to prevent the protruding piece 65, which has a spherical tip with an outer diameter substantially the same as the inner diameter of the rotatable receiving portion 44, from coming off, and it is possible to further stabilize the fulcrum for the rotational movement of the second-side grip portion 60.
[0031] Preferably, the metal fitting 100 has a metal plate 90 on the base 40, the metal plate 90 having at least one or more protrusions on the upper and lower surfaces. Figure 7 shows a top view of an example of a metal plate 90 having protrusions 93, 94 and an elongated hole 95 for receiving the bolt 20. The protrusion 93 is a protrusion on the upper surface, convex toward the front of the page. The protrusion 94 is a protrusion on the lower surface, convex toward the back of the page. When the frame of the member to be fixed by the main body 10 and the metal fitting 100 is made of aluminum, an insulating oxide film forms on the surface. By using the metal plate 90 having at least one or more protrusions 93, 94 on the upper and lower surfaces, the protrusions 93, 94 can break through the insulating oxide film, allowing the metal plate 90 to function as an earth plate. Even if the frame of the member to be fixed by the main body 10 and the metal fitting 100 is coated with an insulator other than an oxide film, the protrusions 93, 94 can break through the coating and ensure electrical continuity.
[0032] The number of protrusions 93, 94 is not particularly limited as long as the metal plate 90 functions as an earth plate, but the metal plate 90 preferably has 1 to 10, more preferably 2 to 8, and even more preferably 3 to 6 protrusions 93, 94 on the upper and lower surfaces, respectively.
[0033] The diameter and height of protrusions 93, 94 can be large enough to break through the insulating oxide film or coating on the surface of the fixed member, such as a solar panel, and are, for example, 1 to 5 mm or 2 to 4 mm. Protrusions 93, 94 preferably have sharp central tips so that they can easily break through the insulating oxide film or coating.
[0034] Protrusions 93, 94 are disposed on the upper and lower surfaces of metal plate 90, preferably at positions facing retaining portion 32 of clamp 30, as illustrated in Fig. 7. By disposing protrusions 93, 94 at positions facing retaining portion 32 of clamp 30, the member to be fixed can be pressed between retaining portion 32 of clamp 30 and protrusions 93, 94, causing protrusions 93, 94 to bite into the member to be fixed and the surface of base portion 40.
[0035] The material of the metal plate 90 is not particularly limited as long as it is a material that conducts electricity, but stainless steel is preferable from the viewpoint of weather resistance.
[0036] Preferably, the metal plate 90 has bent portions 91, 92 that are hooked onto the first side edge 41 and the second side edge 42 of the base portion 40. By hooking the bent portions 91, 92 illustrated in Figures 1 and 7 onto the first side edge 41 and the second side edge 42 of the base portion 40, the metal plate 90 can be more easily positioned and placed on the base portion 40.
[0037] The metal plate 90 may have a notch 96 for passing the spacer 43 upward. As illustrated in Figures 3 and 4, by inserting the spacer 43 into the notch 96, the metal plate 90 can be more easily positioned and placed on the base part 40.
[0038] Preferably, the base 40 has a recess 45 on the first side edge 41, the second side edge 42, or both. Cable ties for arranging cables such as wiring earth lines and DC cables can be placed in the recess 45. The cables can be fixed to the recess 45 with the cable ties so that they are positioned below the recess 45. Since the cables are covered by the recess 45, they can be protected from ultraviolet rays. When placing a metal plate 90, the bottom of the recess 45 is recessed below the surface of the metal plate 90, so the metal plate 90 can be placed without interfering with the cable ties.
[0039] The main body 10 is preferably made of aluminum. The main body 10 is lightweight and has excellent corrosion resistance (weather resistance). [Explanation of symbols]
