Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a quick installation clamping block structure for steel profiles. Background Technique

[0002] In the prior art, stretched aluminum is usually used to form purlins for supporting solar panels in a photovoltaic matrix. The stretched aluminum can be formed into special shapes and structures according to the shape of the mold to meet the requirements for the installation and fixation of solar panels on the purlins. However, relatively speaking, the cost is high.

[0003] In some areas, ready-made and low-cost C-shaped steel (or channel steel) is used instead of stretched aluminum profiles as purlins. However, since the C-shaped steel only has an opening groove on the side, it is difficult to use it for fixing the pressing blocks of solar panels, and holes need to be drilled in the C-shaped steel for locking the pressing blocks. Drilling holes in the C-shaped steel will fix the installation position of the pressing blocks. Once the drilling is incorrect and cannot match the preset installation position of the solar panel, re-drilling is required, which will cause construction delays; at the same time, drilling may also affect the overall strength of the C-shaped steel, posing a safety hazard. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick installation clamping block structure for steel profiles, which solves the problems existing in the prior art and can install and fix solar panels on the C-shaped steel without drilling holes.

[0005] To achieve the above object, the solution of the utility model is:

[0006] A quick installation clamping block structure for steel profiles includes a hook member relatively fixed to the C-shaped steel, a pressing block for pressing the solar panel on the upper surface of the C-shaped steel, and bolts and nuts; the hook member includes a body and a hook portion integrally connected to the lower surface of the body; a first through hole for the nut to movably cooperate is provided in the body, and a second through hole penetrating to the upper surface of the body is provided above the first through hole; the hook portion is hooked on the upper flange of the C-shaped steel; the nut is arranged in the first through hole and is opposite to the second through hole; the bolt sequentially passes through the pressing block and the second through hole and is threadedly connected to the nut; when the bolt is tightened, the distance between the pressing block and the hook member is reduced.

[0007] The pressing block is a side pressing block, and a pressing plate for pressing the edge of the solar panel is provided on one side thereof. Alternatively, the pressing block is a middle pressing block, and pressing plates for pressing the edges of the solar panel are provided on both sides thereof.

[0008] The quick installation clamping block structure for steel profiles further includes a washer arranged between the bolt and the pressing block.

[0009] Protrusions are provided on both sides of the groove of the hook portion, and the inside of the protrusions is hollowed out.

[0010] Alternatively, a relief groove is provided in the groove of the hook portion, and the relief groove is located at the rear side of the groove.

[0011] Preferably, an arc surface is provided at a position of the outer side surface of the hook portion opposite to the relief groove.

[0012] After adopting the above technical solution, the utility model has the following technical effects:

[0013] The utility model can reduce the distance between the pressing block and the hook member by tightening the bolt, so as to press and fix the solar panel on the upper surface of the C-shaped steel. There is no need to drill holes in the C-shaped steel anymore, and the installation position is more flexible, enabling rapid installation; the pressing block, bolt and nut are all ready-made accessories, and only the hook member needs to be processed, with lower cost and faster molding; during installation, the solar panel can be first placed at the preset installation position on the upper surface of the C-shaped steel, and then the hook member and the pressing block pre-assembled into a whole through the bolt and nut are placed on the side of the C-shaped steel, so that the hook portion of the hook member hooks on the upper flange of the C-shaped steel and the bolt is tightened, and the installation is quite convenient and fast.

Detailed implementation manner

[0024] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0025] Refer to Figures 1 - 8 As shown, the present invention discloses a quick installation clamping block structure for profiled steel, including a hook member 1 fixedly relative to the C-shaped steel 10, a pressing block 2 for pressing the solar panel 20 onto the upper surface of the C-shaped steel 10, and a bolt 3 and a nut 4.

[0026] The hook member 1 includes a body 11 and a hook portion 12 integrally connected to the lower surface of the body 11; a first through hole 111 for the nut 4 to movably cooperate is provided in the body 11, and a second through hole 112 penetrating to the upper surface of the body 11 is provided above the first through hole 111; the hook portion 12 is hooked on the upper flange 101 of the C-shaped steel 10.

[0027] The nut 4 is arranged in the first through hole 111 and is opposite to the second through hole 112.

[0028] The bolt 3 sequentially passes through the pressing block 2, the second through hole 112 and is threadedly connected to the nut 4; when the bolt 3 is tightened, the distance between the pressing block 2 and the hook member 1 is reduced.

[0029] Through the above solution, the present invention can reduce the distance between the pressing block 2 and the hook member 1 by tightening the bolt 3, thereby pressing and fixing the solar panel 20 on the upper surface of the C-shaped steel 10. There is no need to drill holes in the C-shaped steel 10, and the installation position is more flexible, enabling quick installation; the pressing block 2, the bolt 3 and the nut 4 are all ready-made accessories, and only the hook member 1 needs to be processed, with lower cost and faster molding; during installation, the solar panel 20 can be first placed at the preset installation position on the upper surface of the C-shaped steel 10, and then the hook member 1 and the pressing block 2 pre-assembled into a whole through the bolt 3 and the nut 4 are placed on the side of the C-shaped steel 10, so that the hook portion 12 of the hook member 1 is hooked on the upper flange 101 of the C-shaped steel 10 and the bolt 3 is tightened, and the installation is quite convenient and fast.

[0030] See Figures 1 - 4 , which shows the first embodiment of the present invention.

[0031] In the first embodiment, the above-mentioned pressing block 2 is a side pressing block, that is, there is only a pressing plate 21 for pressing the edge of the solar panel 20 on one side.

[0032] In the first embodiment, a washer 5 is further included and is disposed between the bolt 3 and the pressing block 2.

[0033] In the first embodiment, convex portions 121 are disposed on both sides of the groove of the hook portion 12, and the convex portions 121 are hollowed out. By designing the convex portions 121, the thickness of the front and rear sides of the hook portion 12 can be increased, thereby improving the strength.

[0034] See Figures 5 - 8 , which shows the second embodiment of the present invention.

[0035] In the second embodiment, the pressing block 2 is a medium pressing block, that is, pressing plates 21 for pressing the edges of the solar panel 20 are disposed on both the left and right sides.

[0036] In the second embodiment, a washer 5 is further included and is disposed between the bolt 3 and the pressing block 2.

[0037] In the second embodiment, a relief groove 122 is disposed in the groove of the hook portion 12, and the relief groove 122 is located at the rear side of the groove. By designing the relief groove 122, space can be provided for the movement of the upper flange 101 in the groove, and the hook member 1 can be hooked onto the upper flange 101 in a rotational manner, making the installation more convenient.

[0038] Further, an arc surface 123 is disposed at a position on the outer side surface of the hook portion 12 opposite to the relief groove 122, for strengthening the thickness of the hook portion 12 to avoid the problem of insufficient strength after the relief groove 122 is opened.
