Be used for photovoltaic power generation new support device for engineering

The utility model discloses a be used for photovoltaic power generation new support device for engineering, including first photovoltaic supporting structure purlin and second photovoltaic supportingstructure purlin, first photovoltaic supporting structure purlin and second photovoltaic supporting structure purlin are thin wall C type steel purlin, the bottom of first photovoltaic supporting structure purlin and second photovoltaic supporting structure purlin is impartial to having seted up the connecting hole. The utility model discloses in, at first present most of photovoltaic supporting structure purlins U type steel purlin in general use, but constantly changeable along with support structural style, the purlin span is corresponding increasing also, U type steel purlin's bad news steel volume escalation, cost escalation. Adoption thin wall C type steel purlin's the more next pact of advantage is obvious, both can satisfy the stress characteristic of large -span photovoltaic engineering supporting structu
