Building structure and heat preservation integrated outer wall maintenance system

A building structure and heat preservation integrated outer wall maintenance system relates to the technical field of building outer wall maintenance and comprises a climbing frame, a spraying device, a control system and a water supply main pipe. The at least three sets of spraying devices are sequentially arranged on the climbing frame in the height direction of the building, each spraying device comprises a spraying pipeline extending around the outer wall of the building and a plurality of sprayers arranged on the spraying pipeline, each wall face, with the width larger than 1000 mm, of the outer wall at least corresponds to one sprayer, and the multiple spraying pipelines are connected to a water supply main pipe through water supply branch pipes; the control system comprises valves arranged on the water supply branch pipes, humidity sensors used for detecting the humidity of the outer wall and a controller in signal connection with the valves and the humidity sensors. Water is automatically sprayed to t
