Spacing bars embedded short distance on the same supporting truss. Under short reinforcement embedded node spacing position to support truss pitch twice, both intervals. Wall junction node should have sufficient strength, the strength of concrete anchor at no less than 15MPa. Buttresses supporting truss rail and pull one end of the pole should be drilled Φ14 perforations, the embedded directly into the sleeve of short bars then bent rebar exposed parts to prevent pro-lapse.

Masonry should be set aside where the holes, so that when removing the scaffolding tube and then bent steel finish straight, pull the crossbar and buttresses short stays sets out the embedded steel. Crossbar struts and buttresses pull the other end of the pole anchored by fasteners.

An upper rail supporting truss scaffolding pole roots must be Twill is coupled to prevent slipping down the pole.

Supporting truss bracing double steel pipe assembling, belly bar should be set according to need support truss set size, but the distance between all sections should not exceed 2.2m. Coupled with the building of the supporting truss above the scaffolding should be strengthened, each vertical spacing every 3-step set point, the horizontal spacing intervals of 3 to straddle it.

Steel pipe used fasteners must be carefully selected, cracked, bent, rusty rotten steel, fasteners must be removed.

A cantilevered steel tube scaffolding every 50m provided a grounding device, such as drunk origin to the transition resistance grounding device on the scaffold than 10Ω, should increase the grounding device.

Cantilevered steel scaffolding should be located at a certain distance deflectors, deflectors should adopt the round bar 6 ~ 8mm, the pole should be connected at the upper and lower deflectors, and higher than the other pole, ground and deflectors application of welding.
