Inspection pitched roof gradient measuring device and using method thereof

The invention provides an inspection pitched roof gradient measuring device and a using method thereof. The device comprises a guiding rule rod attached to a slope roof, a horizontal device for detecting levelness and an adjusting rod for adjusting angles; the guiding rule rod, the horizontal device and the adjusting rod form a triangle, the horizontal device comprises a horizontal rod and a levelused for keeping the horizontal rod horizontal, the horizontal rod is connected with one end of the guiding rule rod, and the level is arranged on the horizontal rod. The measuring device is suitablefor sloping roof formwork gradient inspection, roof concrete pouring gradient inspection and roof leveling layer construction gradient inspection, and due to the fact that the size is calculated in advance, the accuracy is high. During inspection, a leveling instrument is directly seen for inspection, and the result is more accurate. Because each ruler rod is made of a wood square plate, the field material utilization is
