Description

Technical Field

[0001] The utility model relates to the field of photovoltaic support systems, in particular to a locking edge clamp component for a standing seam metal roof. Background Art

[0002] In the current roof photovoltaic support system, the clamps used for vertical seam metal roofs are mostly made of two parts: the main support and the side support. The fixing effect is achieved by tightening the bolts to deform the part of the metal roof that contacts the clamp. During installation, it is necessary to loosen the bolt assembly on the clamp first, and then install the clamp to the planned installation point. Then one person holds the clamp while the other person uses a tool to tighten the bolt assembly to fix it. This process has many steps and requires a lot of time and labor costs. On the other hand, the application scope of existing clamps is small. Different vertical seams on roofs require different clamps. There are many types of clamps, which are inconvenient to choose.

[0003] Therefore, a locking clamp has appeared in the market, such as a skylight protection device and a metal roof with the device, including a standing seam locking clamp, which is block-shaped and has a groove inside. The shape of the groove is set to correspond to the external shape of the curled edge of the metal roof, so that it requires the curled edge size of the metal roof to be consistent and is not compatible with the requirements of installing guide rails in the photovoltaic support system.

Detailed implementation manner

[0033] Please refer to Figures 1 - 3 As shown, a hemming fixture assembly for a standing-seam metal roof includes a clamping member 10 and a pressing member 20. The clamping member 10 has a first groove 11 and a first fastener 50. The first groove 11 extends along the length direction of the clamping member 10 for the hemming 30 of the standing-seam metal roof to be embedded. The first fastener 50 passes through the first groove 11 to clamp the hemming 30. The pressing member 20 is detachably fixed to the clamping member 10 and is provided with a second groove 2221. The second groove 2221 is formed on the side of the pressing member 20 opposite to the clamping member 10 to press the guide rail 40.

[0034] In this embodiment, the clamping member 10 is made of aluminum alloy, and the first fastener 50 is an internal hexagon flat-end set screw, but it is not limited thereto.

[0035] Through the assembly of this hemming fixture assembly and the hemming 30 of the standing-seam metal roof, it is convenient to quickly assemble the guide rail 40 onto the standing-seam metal roof together.

[0036] As Figures 4 - 7 shown, the first groove 11 includes two sides 12 and an opening 13. The opening 13 extends along the length direction of the clamping member 10 for the hemming 30 to be embedded. The two sides 12 are located on two opposite sides of the opening 13. The first fastener 50 passes through one of the sides 12 and presses the hemming 30 against the other side 12. In this way, the installation of holes can be avoided to damage the standing-seam metal roof.

[0037] As Figure 4 shown, the opposite surfaces of the two sides 12 are respectively provided with retaining edges 14. The two retaining edges 14 are located at the opening 13 and extend relatively. The retaining edge 14 is a structure protruding outward relative to the side 12.

[0038] In this embodiment, the width of the opening 13 is greater than the thickness of the hemming 30, which is applicable to more hemmings 30 of different sizes to be embedded. And the hemming 30 fits and positions with the retaining edge 14, which is convenient for the first fastener 50 to clamp the hemming 30.

[0039] The guide rail 40 is provided with an installation groove 42 and a clamping groove 41. The installation groove 42 is located at the top of the guide rail 40 and is used for installing the photovoltaic panel. The clamping groove 41 is located on one side of the guide rail 40 opposite to the pressing member 20 and is used to fix the guide rail 40 to other components. A convex edge 411 is provided at the edge of the clamping groove 41. As Figure 8 shown, the pressing member 20 includes a side plate 21 and a bottom plate 22. The side plate 21 is perpendicular to the length direction of the clamping member 10 to abut against the guide rail 40. Specifically, the side plate 21 abuts against one side of the guide rail 40 opposite to the pressing member 20. The bottom plate 22 is vertically fixed to one end of the side plate 21 opposite to the clamping member 10 and is provided with a second groove 2221. The convex edge 411 of the guide rail 40 can be snapped into the second groove 2221.

[0040] The bottom plate 22 includes a fixing portion 221 and a pressing portion 222. The fixing portion 221 is located on the side of the side plate 21 facing away from the guide rail 40. The fixing portion 221 is provided with a mounting hole 2212 and a second fastener 60. The second fastener 60 passes through the mounting hole 2212 and the pressing member 20 to achieve a detachable fixed connection. In this embodiment, the mounting hole 2212 is an elongated hole to cope with the installation error during the installation of the pressing member 20. The pressing portion 222 is located on the side of the side plate 21 facing the guide rail 40. One end of the pressing portion 222 opposite to the clamping member 10 is provided with a second groove 2221. The pressing portion 222 is snapped into the clamping groove 41, and the convex edge 411 is snapped into the second groove 2221.

[0041] A protrusion 2211 is further provided on one side of the fixing portion 221 opposite to the clamping member 10, and the protrusion 2211 extends along the length direction of the guide rail 40.

[0042] As Figure 3 shown, in this embodiment, when installing the second fastener 60, the protrusion 2211 will first abut against the lower clamping member 10, so that the pressing portion 222 on the side of the bottom plate 22 in contact with the guide rail 40 can be locked tighter.

[0043] As Figure 8 shown, a plurality of ribs 2222 are provided at the bottom of the pressing portion 222. The plurality of ribs 2222 are spaced apart and extend along the length direction of the guide rail 40, increasing the friction between the pressing member 20 and the guide rail 40 and further pressing the guide rail 40.

[0044] The first groove 11 runs through both sides of the clamping member 10 in the length direction. The pressing member 20 is detachably fixed to one side of the clamping member 10 in the direction perpendicular to the length direction, so as to be applicable to the situation where the folding direction of the hem 30 of the metal roof is upright or horizontal.

[0045] As Figure 1 shown, the folding direction of the hem 30 of the metal roof is horizontal, and the pressing member 20 is detachably fixed to one side edge 12 of the clamping member 10.

[0046] AsFigure 10 As shown, the folding direction of the rolled edge 30 of the metal roof is upright, and the pressing member 20 can also be detachably fixed to the clamping member 10.

[0047] like Figure 8 As shown, the second fastener 60 includes a bolt 601, a washer 602 and a washer 603, the washer 602 and the washer 603 are sleeved on the bolt 601, and the washer 602 is located at the bottom end of the head of the bolt 601, and the washer 603 is located at the bottom end of the washer 602. In this embodiment, the washer 602 is a spring washer 602, and the washer 603 is a butterfly washer 603.

[0048] During construction, firstly, partially screw the first fastener 50 into the clamping member 10 by hand, then align one side of the opening 13 of the clamping member 10 with the butt hem 30 of the metal roof, then install the clamping member 10 onto the hem 30, then tighten the first fastener 50 with a torque wrench or an electric tool and repeat this step until the first fastener 50 reaches the recommended torque; then partially screw the second fastener 60 into the clamping member 20 by hand, press the protrusion 2211 of the fixing portion 221 against the clamping member 10 so that the clamping portion 222 can be tilted, then place the guide rail 40 on the clamping member 10, then snap the clamping portion 222 of the clamping member 20 into the slot 41 of the guide rail 40, and snap the convex edge 411 into the second slot 2221, and finally tighten the second fastener 60 to complete the installation.
