4) The transverse sweeping rods should be fixed to the vertical poles close to the bottom of the longitudinal sweeping rods with right-angle fasteners.
(V) Acceptance standards for the main body of the scaffolding
1) The acceptance of the main body of the scaffolding is calculated according to the construction needs. For example, the spacing between the vertical poles of the ordinary scaffolding must be less than 2m; the spacing between the large horizontal bars must be less than 1.8m; and the spacing between the small horizontal bars must be less than 2m.
2) The vertical deviation of the pole should be inspected according to the height of the frame, and its absolute difference should be controlled at the same time
3) When the scaffolding poles are extended, except for the top of the top layer, the joints of the other layers and steps must be connected with butt fasteners. The joints of the scaffolding frame should be staggered
4) The large crossbar of the scaffolding shall not be greater than 2 meters and must be set continuously
5) The small crossbar of the scaffolding should be set at the intersection of the pole and the large crossbar and must be connected to the pole with a right-angle fastener
6) The fasteners must be used reasonably during the erection of the frame, and they must not be substituted or misused. Fasteners with slipped threads or cracks must never be used in the frame.
(VI) Acceptance criteria for scaffolding boards
1) After the scaffolding is erected at the construction site, the scaffolding boards must be fully laid and the scaffolding boards must be correctly connected. At the corners of the frame, the scaffolding boards should be staggered and overlapped and must be tied firmly. Uneven places should be leveled and nailed with wooden blocks;
2) The scaffolding boards on the working layer should be laid flat, fully packed, and firmly tied. The length of the scaffolding board probe at the end 12-15CM away from the wall should not be greater than 20CM. The spacing of the horizontal bars should be set according to the use of the scaffolding. The scaffolding boards can be laid flat or overlapped.
(VII) Acceptance of scaffolding and wall ties
There are two types of wall ties: rigid wall ties and flexible wall ties. Rigid wall ties should be used at the construction site. For scaffolding with a height of less than 24 meters, wall ties need to be set up in 3 steps and 3 spans. For scaffolding with a height between 24 meters and 50 meters, wall ties need to be set up in 2 steps and 3 spans.
(VIII) Acceptance of scaffolding scissor braces
1) Scaffoldings above 24m must be equipped with a scissor brace at each end of the outer facade and should be set continuously from bottom to top. Load-bearing and special racks should be equipped with multiple continuous scissor braces from bottom to top. The angle between the diagonal rod of the scissor brace and the ground should be between 45° and 60°. The width of each scissor brace should not be less than 4 spans and should not be less than 6 meters;
2) When the frame is higher than 24 meters, scissor braces must be set continuously from low to high.
(IX) Acceptance of scaffolding upper and lower measures
1) There are two types of scaffolding upper and lower measures: hanging ladders and setting up “Z”-shaped walkways or inclined walkways;
2) Ladders must be hung vertically from low to high and must be fixed every 3 meters vertically. The top hook must be tied firmly with 8# lead wire;
3) The upper and lower walkways must be set up at the same height as the scaffolding. The width of the pedestrian walkway must not be less than 1 meter, the slope is 1:6, and the width of the material transport walkway must not be less than 1.2 meters and the slope is 1:3.

2) A dense mesh must be set on the outside of the construction scaffolding, and the dense mesh must be flat and complete;
3) Anti-fall measures must be set up every 10-15 meters of the vertical height of the scaffolding, and a dense mesh must be set up on the outside of the frame promptly. The inner safety net must be pulled tight when laid, and the safety net fixing rope must be tied around a fixed and reliable place.
