1. The template support frame should select the vertical pole spacing and step distance according to the load it bears. The bottom longitudinal and transverse horizontal bars are used as sweeping bars, and the height from the ground should be less than or equal to 350mm. The bottom of the vertical pole should be equipped with an adjustable base or a fixed base; the length of the upper end of the vertical pole including the adjustable screw extending from the top horizontal pole shall not be greater than 0.7m.
2. Requirements for setting diagonal bars of formwork support frame:
① When the distance between vertical bars is greater than 1.5m, a full-height special diagonal bar should be set at the corner, and a full-height eight-shaped diagonal bar or scissor brace should be set in each row and column in the middle;
② When the distance between vertical bars is less than or equal to 1.5m, vertical scissor braces should be set continuously from bottom to top around the formwork support frame; vertical scissor braces should be set continuously from bottom to top in the middle longitudinal and transverse directions, and the spacing should be less than or equal to 4.5m;
③ The angle between the diagonal bar of the scissor brace and the ground should be between 45° and 60°, and the diagonal bar should be buckled with the vertical bar at each step
3. When the height of the formwork support frame is greater than 4.8m, horizontal scissor braces must be set at the top and bottom, and the spacing between the horizontal scissor braces in the middle should be less than or equal to 4.8m.
