The cantilever length of the adjustable support of formwork support extending out of the top horizontal bar or double channel steel joist is forbidden to exceed 650mm, the exposed length of screw is forbidden to exceed 400 mm, and the length of the adjustable support inserted into the column or double channel steel joist shall not be less than150 mm. ..
The adjustable top bracing and bottom bracing of the turnbuckle scaffold have a diameter of 48.3mm, a wall thickness of 3.2mm, an inner diameter of 4 1.9mm and a diameter of 38mm, which can not only ensure easy insertion of the upright, but also not cause too much shaking, and the safety factor is higher than that of products with smaller diameters.
Matters needing attention of plate buckle scaffold
When using fastener-type double-row scaffolding, the erection height shall not exceed 24m. The geometric dimensions of scaffolding can be selected according to the operation requirements. The step distance between adjacent horizontal poles is preferably 2m, and the vertical poles in general offices are preferably 1.5m or 1.8m, preferably no more than 2. 1m, and the horizontal distance of the vertical poles is preferably 0.9m or1.2m.. ..
On the first floor of the scaffold, it is best to choose different lengths of vertical rods to be staggered. The vertical distance of staggered vertical poles should not be less than 500mm, and a vertical diagonal bar should be set every five spans along the outside longitudinal direction of scaffolding, or bracing should be set every five spans.
