Concrete roof photovoltaic support

The utility model relates to a concrete roof photovoltaic support, and relates to the technical field of solar photovoltaic supports, the concrete roof photovoltaic support comprises a support beam and a purline, the purline is detachable from a solar panel through a connecting mechanism, and two bending parts are formed at the top end of the purline. When the solar panel is subjected to a downward wind load, the load is transmitted to the purline through the pressing code, the stressed top end of the purline tends to expand outwards or incline inwards, the connecting plate limits the two bent parts, and the action of force is mutual, so that the force opposite to the stress of the bent parts is generated on the connecting plate, and the solar panel is prevented from being damaged. When the wind load is upward, the pressure code and the connecting plate are matched to improve the stability of the joint of the solar panel and the purline, so that the probability that the solar panel deforms to generate recesse
