1, outside frame scaffolding: from the wall between 300-350 mm. Foot hand width of 1.0 meters, (poling cross net from), longitudinal vertical pole distance of 1.8 meters, the step between 1.9 2.0 meters high (engineering height according to the unit selection)

2, rail lateral elongation is not less than 100 mm, inside the outside walls from 100 ~ 150, bar should step up and down cross set in different sides of the post, making post hand load eccentric force is reduced, is apart from the wall space set level safety net.

3, column and horizontal frame rod coupling adopt cross fasteners, bracing and brace and rotating fastener be used between the pillar and the ledger, the two are not allowed to be wrong.

4, longitudinal rod, an extension application docking fastener, scissors extension application poles rotating fastener, two adjacent longitudinal rod joint should not be set up within the synchronization or with cross, recently to the master node in each joint distance should not be more than 1/30 of the longitudinal spacing lap length should be not less than 1.0 m, should set three rotating fastener fixed light distance.

5, fastening should conform to the requirements of the fasteners used, the strength is too small, fastener is easy to slip force will cause fastener damage and fracture, in general force major 40-70 n/M.

6, at the bottom of the column should be gap crossing with different length of steel tube and the adjacent column to joint in sync is high, the synchronization between two adjacent joint of a vertical bar in the high direction staggered distance should not be less than 500 mm, joint distance should not be greater than 500 mm. Caused by the fall weak section of stagger.
