According to the engineering characteristics: double steel scaffolding tube building pitch control stand about 30cm. We must meet the construction schedule. Erection once a height above the operating level step frame. Pole row spacing of not more than 2m, spacing 1.2m, on backgammon as 1.8m. Bottom steel pole must be connected to different lengths staggered position, the connection point of adjacent pole should not be at the same height. In addition to the use of lap top pole connector connection, the rest must be docking fastener connection, lap length not less than 1m.

The first root vertical pole shall be temporarily located across every 6 a and the ground was 45 ° ~ 60 ° the bracing. Parapet above the top of the top pole 1m, above the cornice epithelium is not less than 1.5m. Scaffolding should be closed form, from one end of the scaffold with step within four weeks must pay longitudinal horizontal bar rings, horizontal bar wall to wall decor the distance is 15 ~ 20cm. each pole base must set up a 20cm vertical and horizontal sweep shot, with right angle fasteners and fixing pole.

Rachel lever must be pre-buried in the beam in the upper floor before pouring concrete until the concrete strength of more than 50% of design strength after the pole in Cartesian fastener, short steel braced.

Diagonal tube should be set on the outside of the scaffolding tube pole, its lap length not less than 1m, less than two rotating fastener is fixed spacing should not be less than 80cm. Scissors diagonal bar and the horizontal angle of 45 ° ~ 60 °, continuously provided along the height from the bottom up. Should be located at both ends of the corner scissors every 10m should be set to a scissors, a width of 3 to 5 pole pitches.
