3, the adoption steel pipe for stud, its outer diameter to the 48 -
51 mm steel tube wall thickness 3 -
5 mm long lap poling, must have enough strength, the form of lap joint pole lap to use 'one word' adversary card buckle.
Want close, 4, the laying of scaffold board and firm, lap plate end to drown putlog 15 cm, scaffold board fixed on both ends, it is strictly prohibited to entities probe springboard.
5, double bent rod away from the wall distance (1.
4 m, poling from inside wall distance not greater than 20 cm, biggest stud spacing but 1.
6, wood, steel and bamboo board must check before construction, the springboard itself is safety hidden trouble, such as crack, the edge, etc.
