First, the principle of setting the horizontal scissors
【normal type】
① Set horizontal scissor support at the top;
②When the erection height exceeds 8m or the total construction load is greater than 15KN/㎡ or the concentrated line load is greater than 20KN/m, the top and bottom scissor braces should be installed and the spacing between the horizontal scissor braces should not exceed 8m.
【Enhanced】
① Set horizontal scissor support at the top;
②When the erection height exceeds 6m or the total construction load is greater than 15KN/㎡ or the concentrated line load is greater than 20KN/m, the top and bottom scissors should be installed and the spacing between the horizontal scissors should not exceed 6m.
Second, the principle of vertical scissor support setting
【normal type】
The outside is full, the inside is set every 5m-8m, and the width of the scissors is 5m-8m.
【Enhanced】
①When the vertical and horizontal spacing is 0.9m-1.2m, the outer side is full, the inner side is set every 4 spans, and the width of the scissor brace is 4 spans;
②When the vertical and horizontal spacing is 0.6m-0.9, the outer side is full, the inner side is set every 5 spans, and the width of the scissor brace is 5 spans;
③When the vertical and horizontal spacing is 0.4m-0.6, the outer side is full, the inner side is set every 3m-3.2m, and the width of the scissors is 3m-3.2 spans.
