Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation device technology, and in particular to a column connection structure for photovoltaic support. Background Technology

[0002] Existing photovoltaic brackets all use columns for support and are erected high in the air to avoid being blocked by objects and to obtain more sunlight, thereby improving the utilization rate of solar energy.

[0003] Before installation, a mounting plate needs to be welded to one end of each column. Then, one column is used as a base, and concrete is poured to fix the other end of the column that serves as the base in the set position. Finally, fasteners are used to fix one end of the two columns together through the two mounting plates.

The two columns 1 can be fixed by the connectors 2 through these connection structures and the corresponding gap between the two columns 1 can be covered. No welding mounting plate is required.

[0042] In some embodiments, the column 1 is an H-shaped steel structure, and the connector 2 is a vertically arranged flat steel plate;

[0043] The first connector 2 has its plate surface abutting against the same plate surface of the two longitudinal web plates 12, and the second connector 2 has its plate surface abutting against the other plate surface of the two longitudinal web plates 12, and a plurality of first fasteners pass through the first connector 2, the longitudinal web plate 12 and the second connector 2 in sequence, and the first connector 2 and the second connector 2 are connected.

[0045] like Figure 3 and Figure 4 In the embodiment shown, the connection between the two columns 1 of the H-shaped steel members, which are opposite each other, can be fixed and strengthened from four directions by the cooperation of four connectors 2 of flat steel plates, multiple first fasteners and multiple second fasteners, thereby improving the bending resistance of the connection between the two columns 1.

[0046] In other embodiments, both the column 1 and the connector 2 are vertically arranged C-shaped channel steel;

[0047] The outer peripheral surface of the connector 2 is in close contact with the inner peripheral surfaces of the two columns 1 located at the connection point, where they abut against each other.

[0057] Preferably, the first fastener and the second fastener are bolts or blind rivets.

[0058] Bolts or blind rivets of different diameters can be selected as the first or second fasteners according to the required bending strength.
