Description

Technical Field

[0001] The utility model relates to the field of photovoltaic equipment, and in particular comprises a clamp for fixing a BIPV photovoltaic bracket. Background Art

[0002] With the development of environmental problems, the country has implemented a sustainable development strategy, issued a call for energy conservation and emission reduction, and developed solar energy green environmental protection. Photovoltaic building integration (BIPV) has been rapidly developed as a new concept of solar power generation. Photovoltaic building integration installs solar photovoltaic power generation arrays on the outer surface of the building's enclosure structure to provide electricity. Photovoltaic building integration is suitable for most buildings, such as roofs, curtain walls, ceilings, etc. For building-integrated roof power generation systems, it has very strict requirements for waterproofing. The existing waterproofing measures mainly set up water guides in the fixed brackets of photovoltaic panels to drain water, so that concrete and color steel tile roofs are not eroded by water.

[0003] To build a photovoltaic building integrated power generation system on a concrete roof, you need to install the foundation and bracket first, and then install the primary and secondary water channels and components on the bracket. The main water channel needs to be effectively connected to the bracket beam. The bracket beam is made of U-shaped steel, and the edge of the main water channel is connected to the curling of the bracket beam. It is generally fixed by self-tapping screws. This fixing method has the advantages of simple construction methods and the disadvantages of high installation difficulty due to the limited curling size of the bracket beam.

[0004] Therefore, it is urgent to improve and upgrade the curling connection method between the edge of the main water tank and the support beam to directly improve the efficiency of on-site construction. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a clamp for fixing a BIPV photovoltaic bracket.

[0006] This clamp for fixing the BIPV photovoltaic bracket is used for fixing the main water tank and the U-shaped steel beam, and includes: U-shaped bolts, pressure blocks and gaskets. The main water tank is placed above the U-shaped steel beam, and the main water tank is arranged perpendicular to the U-shaped steel beam. One end of the pressure block is fixed to the main water tank, and the other end is pressed on the U-shaped steel beam.

[0007] The pressure block has two holes, and the two ends of the U-bolt pass downward through the two holes on the pressure block and extend to the bottom of the U-shaped steel beam. The two ends of the U-shaped bolt are connected by a gasket under the bottom of the U-shaped steel beam and fixed by bolts.

[0008] Preferably, the distance between the two holes on the pressing block is greater than the width of the U-shaped steel beam.

[0009] Preferably, one end of the pressing block is fixedly connected to the main water tank by a self-tapping screw.

[0010] Preferably, the top ends of the flanges on both sides of the U-shaped steel beam are provided with curling edges, and the curling directions on both sides of the U-shaped steel beam are both toward the inner side of the U-shaped steel beam.

[0011] Preferably, the cross-section of the main water trough is M-shaped, and horizontal edges are provided on both sides of the M-shape. When the main water trough is placed above the U-shaped steel beam, the edges are pressed on the rolled edge of the U-shaped steel beam.

[0012] The beneficial effects of the utility model are:

[0013] A clamp is proposed to clamp the main water tank and the U-shaped steel beam and connect them with U-shaped bolts to achieve the purpose of reliable connection between the U-shaped steel beam and the main water tank, avoiding slippage between the U-shaped steel beam and the main water tank. It is suitable for BIPV photovoltaic brackets on concrete roofs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the embodiments. The description of the following embodiments is only used to help understand the utility model. It should be pointed out that for ordinary people in this technical field, the utility model can also be modified in some ways without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0019] The flange tops on both sides of the U-shaped steel beam 2 are provided with curling edges, and the curling edge width does not exceed 20 mm, which requires high construction accuracy. And the curling edges on both sides of the U-shaped steel beam 2 are all directed toward the inside of the U-shaped steel beam 2.

[0020] The cross-section of the main water tank 1 is M-shaped, and horizontal edges are arranged on both sides of the M-shape.

[0021] The traditional connection method between the main water tank and the U-shaped steel beam is as follows Figure 1 As shown, the main water tank 1 and the U-shaped steel beam 2 are only fixed together by self-tapping screws 3, which is not firm.

[0022] In this embodiment, a clamp for fixing a BIPV photovoltaic bracket is used to fix the main water tank 1 and the U-shaped steel beam 2. Figures 2 to 3 As shown, the clamp for fixing the BIPV photovoltaic bracket includes: U-bolts 4, pressure blocks 5 and gaskets 6. The main water tank 1 is placed above the U-shaped steel beam 2, and the main water tank 1 is arranged perpendicular to the U-shaped steel beam 2. When the main water tank 1 is placed above the U-shaped steel beam 2, the edge is pressed on the curling edge of the U-shaped steel beam 2. One end of the pressure block 5 is fixed to one side edge of the main water tank 1 by a self-tapping screw 3, and the other end is pressed on the curling edge of the U-shaped steel beam 2.

[0023] The pressing block 5 is provided with two holes, and the distance between the two holes is greater than the width of the U-shaped steel beam 2. The two ends of the U-shaped bolt 4 pass downward through the two holes on the pressing block 5 and extend from both sides of the U-shaped steel beam 2 to the bottom. The two ends of the U-shaped bolt 4 are connected by a gasket under the bottom of the U-shaped steel beam 2 and fixed by bolts.

[0024] The application of this clamp in engineering solves the problem of small contact area and inconvenient construction between the main water tank 1 and the U-shaped steel beam 2, and improves the construction quality and efficiency of the on-site bracket. It facilitates the construction and installation of photovoltaic brackets and improves construction efficiency. It is generally applicable to BIPV brackets on concrete roofs.
