Double tubular scaffolding shall be 30cm away from the building.
Summary: Double steel scaffolding mobile vertical spacing control in buildings around 30cm.Erection height above the operating level once a step frame. Pole row spacing of not more than 2m, spacing 1.2m, on backgammon as 1.8m.
According to the engineering characteristics: double steel scaffolding mobile vertical spacing control in buildings around 30cm. We must meet the construction schedule. Erection height above the operating level once a 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 must be staggered position, the connection point of adjacent pole should not 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. When the first vertical root pole every 6 should temporarily located across one and the ground was 45 ° ~60 ° the bracing. Parapet above the top of the top pole 1m, up cornice epithelium is not less than 1.5m. Mobile scaffolding should be used in closed form, moving from one step inside the scaffolding with longitudinal horizontal bar must circle around the cross, one end of the horizontal scaffolding tube against the wall to wall from the decorative surface is 15 ~ 20cm.
Each 20cm. each pole base must set up a 20cm vertical and horizontal sweep shot, with right angle fasteners and fixing pole. Let process points cantilevered steel mobile scaffolding erection and erection must be constructed in accordance with the order of construction design requirements.
