Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a steel fast installation block structure. Background Art

[0002] In the prior art, the purlins for supporting solar panels are usually extruded aluminum profiles. The advantage of extruded aluminum is that it can be formed into special shapes and structures according to the shape of the mold to meet the requirements for installing and fixing solar panels on the purlins. However, relatively speaking, the cost is high.

[0003] In some photovoltaic matrices, ready-made and low-cost C-shaped steel (or channel steel) is used instead of extruded aluminum profiles as purlins. However, since the C-shaped steel only has an open groove on the side, it is difficult to use it for fixing the pressing blocks of solar panels. Holes need to be drilled on the C-shaped steel and bolts are used to lock the pressing blocks. The defects of this similar installation method are as follows: Drilling holes on the C-shaped steel will fix the installation position of the pressing blocks. Once the drilling goes wrong and cannot match the preset installation position of the solar panel, re-drilling must be carried out, which will cause construction delays; at the same time, too many holes 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 steel fast installation block structure to solve the problems existing in the prior art and enable the installation and fixation of solar panels on C-shaped steel without drilling holes.

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

[0006] A steel fast installation block structure includes a limiting member fixedly relative to the C-shaped steel, a pressing block for pressing down the solar panel, and bolts and nuts; on both sides of the upper surface of the limiting member, a limiting groove and a supporting flange are respectively provided, and an activity groove for the nut to be movably fitted is arranged inside the limiting member, and a through hole penetrating to the upper surface of the limiting member is arranged above the activity groove; the nut is arranged in the activity groove and is opposite to the through hole; the bolt sequentially passes through the pressing block and the through hole and is threadedly connected with the nut; when installing the solar panel, the upper flange of the C-shaped steel is embedded in the limiting groove, the pressing block presses down on the edge of the solar panel, the bolt is tightened to reduce the distance between the pressing block and the limiting member, and the supporting flange abuts against the lower surface of the solar panel.

[0007] At least one side of the pressing block is provided with a pressing plate for pressing down the edge of the solar panel.

[0008] The steel fast installation block structure further includes a washer arranged between the bolt and the pressing block.

[0009] On one side of the upper surface of the limiting member, two parallel limiting flanges protrude, and a limiting groove is formed between the limiting flanges and the upper surface of the limiting member, and the height of the limiting flange is lower than that of the supporting flange.

[0010] After adopting the above technical solution, the utility model has the following technical effects:

[0011] The utility model can reduce the distance between the pressing block and the limiting 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, and the installation position is more flexible, enabling rapid installation. Moreover, the lower surface of the solar panel is supported by the C-shaped steel and the supporting flange on both sides of the bolt respectively, and the limiting member is not easily deformed when the bolt is tightened, and the structure is more stable; the pressing block, bolt and nut are all ready-made accessories, and only the limiting member needs to be processed, with lower cost and faster forming; 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 limiting 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 limiting groove of the limiting member hooks the upper flange of the C-shaped steel and the bolt is tightened, and the installation is quite convenient and fast.

[0018] In order to further explain the technical solution of the utility model, the utility model will be elaborated in detail through specific embodiments below. <F

[0019] Refer to Figures 1-4 As shown, the utility model discloses a quick installation clamping block structure for profiled steel, including a limiting member 1 fixedly opposite to the C-shaped steel 10, a pressing block 2 for pressing down the solar panel 20, and a bolt 3 and a nut 4;

[0020] On both sides of the upper surface of the limiting member 1, a limiting groove 11 and a supporting flange 12 are respectively provided, and an activity groove 13 for the nut 4 to be movably fitted is arranged in the limiting member 1. Above the activity groove 13, a through hole 131 penetrating to the upper surface of the limiting member 1 is provided.

[0021] The nut 4 is arranged in the activity groove 13 and is opposite to the through hole 131.

[0022] The bolt 3 sequentially passes through the pressing block 2, the through hole 131 and is threadedly connected with the nut 4.

[0023] When installing the solar panel 20, the upper flange 101 of the C-shaped steel 10 is embedded in the limiting groove 11, the pressing block 2 presses down on the edge of the solar panel 20, the bolt 3 is tightened to reduce the distance between the pressing block 2 and the limiting member 1, and the supporting flange 12 abuts against the lower surface of the solar panel 20.

[0024] Through the above scheme, the utility model can reduce the distance between the pressing block 2 and the limiting member 1 by tightening the bolt 3, so as to tightly fix 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 anymore, and the installation position is more flexible, enabling quick installation. Moreover, both sides of the bolt 3 are respectively supported by the C-shaped steel 10 and the supporting flange 12 on the lower surface of the solar panel 20, and the limiting member 1 is not easily deformed when the bolt 3 is tightened, and the structure is more stable; the pressing block 2, the bolt 3 and the nut 4 are all off-the-shelf accessories, and only the limiting member 1 needs to be processed, with lower cost and faster forming; 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 limiting 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 limiting groove 11 of the limiting member 1 hooks 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.

[0025] The following shows specific embodiments of the utility model.

[0026] The above pressing block 2 can be a side pressing block or a middle pressing block, that is, at least one side of the pressing block 2 is provided with a pressing plate 21 for pressing down the edge of the solar panel 20.

[0027] In this embodiment, a washer 5 is further included and arranged between the bolt 3 and the pressing block 2, which plays a buffering role during locking.

[0028] On one side of the upper surface of the above limiting member 1, two parallel limiting flanges 14 protrude. The limiting flanges 14 and the upper surface of the limiting member 1 enclose the above limiting groove 11, and the height of the limiting flanges 14 is lower than that of the supporting flange 12. Compared with the form of forming the limiting groove 11 by opening a groove on the upper surface of the limiting member 1, the limiting flanges 14 protrude to limit the upper flange 11 of the C-shaped steel 10, and the strength of the limiting member 1 is higher.
