Note: top railing height from the floor or roof to the handrail handrail vertical height calculation, such as the bottom have width is equal or greater than 0.22m and height less than or equal to 0.45M can step position, should be set foot position calculation of top surface.
3 bars from the floor or roof 0.10m height should not be blank;
4 houses, nurseries, kindergartens, schools and special for children activities places of the railing must prevent the use of children climbing structure, when the vertical member of rails, the bar spacing should not be more than 0.11M;

"Civil design principles" GB 503522005 provisions
6.6.3 the two balcony, corridor, airport railing height should be more than the height of the center of gravity of the human body, in order to avoid the body close to the railing for center of gravity shift and fall. According to the relevant units in 1980 to 14, body measurements in China: China’s men’s average height was 1656.03mm, converted into the focus of human upright state of the height is 994mm, the height of center of gravity shoes after 99420 = 1014mm, so in the national standard "fixed rail industry" stipulated: "protective railing shall have a height less than 1050mm, so" the provisions of this article 24m below the airport height (equivalent to low layer, multilayer building height) railing height should not be lower than 1.05M, more than 24m airport height (equivalent to high-rise and high-rise residential height) of the rail height should not be lower than 1.10M, for the high-rise buildings, because of high altitude overlooking there will be fear so, increased to 1.10m. Note that when baluster bottom have width is equal or greater than 0.22m and height less than or equal to 0.45M can step position, by stepping on the normal people, people are very easy to set foot on and stood looking (instead of climbing), at the height of the railing as from the ground floor or roof starting, to pole fence handrail top surface height less than the height of the center of mass of the people, very safe, so it should be set foot position calculation of top surface.
Article 4, paragraph 5 for the safety of the protection of children and their special place railings should prevent climbing are constructed using, such as not to do lateral floriation, parapet wall waterproof material head walk along the small brick. When the vertical railing, the net distance between the members should not be greater than 0.11M, in case the head belt passing through and fall. In recent years, in shopping malls and other buildings, some rail vertical bar between the spacing is about 0.20 m, children falling accident, so children can go places and do single vertical bars and rods spacing should not exceed 0.11M.
