Common coupler scaffold, 48 mm steel pipe diameter and wall thickness of 3.5 mm. Length: the factory delivery is 6 meters commonly, the length of the rest are for my own processing according to need. If button is a cuplock of timbering, the length of the ringlock scaffolding tube is commonly 1.2, 1.8, 2.4/3.0 meters four, in order to adjust the height 0.9 meters, 1.5 meters, 2.1 meters of three, but can only be used for the three at the top or the bottom, cross bar is 0.3/0.6/0.9/1.2 meters four.

1, steel couplers, scaffolding, should be paid attention to in the foundation level solid, and set up base plate, and have reliable drainage measures to prevent the water soak a foundation.

2, according to the situation of rod set up the wall and load size, the commonly used open type double row scaffolding rod. Horizontal spacing generally 1.05 ~ 1.55 m, building scaffolding interval is 1.20 ~ 1.35 m, commonly decoration or building, decoration and scaffolding generally is 1.80 m, poling longitudinal from 1.2 ~ 2.0 m, which allows the erection 34 ~ 50 m in height. When for single row, poling cross from 1.2 ~ 1.4 m, poling longitudinal from 1.5 ~ 2.0 m, allow the erection of 24 m in height.

3, longitudinal bar should be set in the inside of the stud, should not be less than 3 across its length, longitudinal rod can use docking coupler, lap may be adopted. If coupler docking methods, docking couplers should be staggered arrangement; If connected by lap, lap length should not be less than 1 m, and shall be equally spaced set three rotating coupler stationary.

4, scaffolding master node (that is, the stud, longitudinal rod, lateral horizontal bar three pole near the buckle contact) must be set at a horizontal ring lock pole with a right-angle coupler hooking and it is forbidden to dismantle.
