The parapet (also known as the granddaughter's wall) is a low wall around the roof of a building. Its main function is not only to maintain safety, but also to apply waterproof bricks at the bottom to avoid water seepage from the waterproof layer or rainwater overflow from the roof. According to the national building code, the height of the parapet on the master's roof is generally not less than 1.1m and the highest is not more than 1.5m..
An ancient bricklayer was busy with her work and had to take her young daughter with her. One day, while building on the roof, her young daughter accidentally fell down and died. The craftsman was heartbroken. In order to prevent the tragedy from happening again, he built a low wall on the roof, and later people named it "parapet".
the height of the parapet depends on whether you are here or not. If you are not here, the height should be no more than 8mm, and if you are here, the height should be no less than 13 mm. When there is a concrete coping, it shall be calculated from the top surface of the floor to the bottom surface of the coping; When there is no concrete coping, it shall be calculated from the top surface of the floor to the top surface of the parapet.
