Low layer thin -walled cold -formed steel constructs roof structure

The utility model discloses a low layer thin -walled cold -formed steel constructs roof structure, including crossbeam, first slope roof beam, second slope roof beam and longeron, the vertical longeron that is provided with is located at the mid point of first slope roof beam, second slope roof beam to first slope roof beam, the fixed welding of second slope roof beam difference symmetry on the crossbeam, be provided with the stiffener between the longeron, the downside of crossbeam is equipped with horizontally dash board, the inboard of first slope roof beam is connected with the swash plate, sets up flutedly in the inboard of first slope roof beam, is close to at the swash plate that one side of first slope roof beam is fixed to be provided with joint portion, is provided with one row of rack in roller corresponding's joint portion, the wheel and rack meshing. The utility model discloses a motor drives gear revolve, makes the swash plate on the first slope roof beam reciprocate, and the gyro wheel reduces the friction that produces when it slides, reduce wearing and tearing, improves life, reduction maintenance frequency, and opening and closing of swash plate is all controlled through the gear, and convenient operation is simple.
