To see the fastening scaffolding
more knowledge of scaffolding and aluminum beam description.
erection of scaffolding should be noted that fastener formed a solid foundation, set up the base and the plate, and a reliable drainage measures to prevent water soaking the foundation.
Horizontal bar should be set vertically inside the pole, its length should not be less than 3 cross-and longitudinal horizontal bar can be docked fasteners, may also overlap. Fastening methods such as the use of docking, the docking fasteners should be staggered; such as connections with lap, lap length not less than 1 m, and such spacing is set to be 3 rotating fastener fixed.
scaffolding master node (ie pole, vertical horizontal bar, horizontal level close to the button bar three contacts) must be set at a horizontal level bar with a right-angle fastener Snap and non-removal. Master node from the center of the two right-angle fastener should not exceed 150mm. In the double scaffolding, the lateral end of the horizontal bar extended the length of the wall should not exceed 0.4 times the horizontal distance pole, and should not be greater than 500mm; operating layer of horizontal non-master node horizontal bar, should be based on supporting spaced scaffold board needs to set the maximum distance should not be greater than the vertical distance of 1 / 2.
The bottom of each pole should be set to the base or plate. scaffolding must be set vertical and horizontal sweep shot. Vertical sweep shot should be fixed at right angles from the base of epithelial fasteners not more than 200mm at the pole on. Horizontal sweep shot should close with right-angle fastener fixed to the bottom of the vertical pole on a sweeping stroke upge0tp. When the pole is not the same height on the basis, you must sweep the floor height of the vertical bars extend to the lower pole fixed with two spans, the height difference should not exceed lm. Pole by the axis of the slope to the top of the slope distance of not less than 500mm.
