The utility model particularly relates to an outdoor interval-type wind-proof suspension device of an aluminum batten suspended ceiling, which solves the problemsthat the suspension structure of the existing aluminum batten suspended ceiling is easy to fall out, and the time and the labor are wasted when in installation. A strip connecting piece with a bolt hole in the middle is arranged above an aluminum batten; clamping grooves used for clamping the aluminum batten are arranged at the two sides of the upper end of the connecting piece; an auxiliary piece vertical to the connecting piece is horizontally arranged above the connecting piece; a bolt hole is arranged on the auxiliary piece; a connecting bolt is screwed in the bolt holes between the auxiliary piece and the connecting piece; the auxiliary piece is arranged in a U-shaped supporting piece with one side being longer; a fastening bolt is arranged between the two sides of the supporting piece above the auxiliary piece in a penetrating way; a connecting plate is fixedly arranged at the upper end of the longer side of the supporting piece; an adjusting bolt fixed with a suspension post penetrates into the connecting plate; and an adjusting nut is screwed on the adjusting bolt positioned at the lower side of the connecting plate. The outdoor interval-type wind-proof suspension device is reasonable and reliable in structural design, can effectively reduce the additional load of the suspended ceiling as the downforce of the suspended ceiling is descended and can improve the suspending effect greatly.
