1.The construction of the scaffolding foundation and base must be calculated according to relevant regulations based on the scaffolding height and on-site soil conditions.
2.Check whether the scaffolding foundation and base are compacted.
3.Check whether the scaffolding foundation and base are level.
4.Check whether there is water accumulation in the scaffolding foundation and base.
(II) Inspection of Scaffolding Drainage Ditches
1.Clear debris from the scaffolding site and level the ground to ensure smooth drainage.
2.Drainage ditches should be installed 500mm to 680mm outside the outermost row of uprights.
3.The width of the drainage ditch should be 200mm to 350mm, and the depth should be 150mm to 300mm. A sump pit (600mm × 600mm × 1200mm) should be installed at the end of the ditch to ensure timely drainage of accumulated water.
4.The top width of the drainage ditch should be 300mm, and the bottom width should be 180mm.
5.The slope of the drainage ditch should be i = 0.5.
(III) Inspection of Scaffolding Base Plates and Footings
1.The inspection of scaffolding base plates and footings should be determined based on the scaffolding height and load.
2.For scaffolding below 24m, the base plate specifications should be (width greater than 200mm, thickness greater than 50mm). Ensure each upright is placed at the center of the base plate, with a base plate area of no less than 0.15 m².
3.The thickness of the base plate for load-bearing scaffolding above 24m must be strictly calculated.
4.The scaffolding footing must be placed at the center of the base plate, with a width greater than 100mm and a thickness of no less than 50mm.
(IV) Inspection of Scaffolding Kickboards
1.Kickboards must be connected to the uprights, and unconnected kickboards are strictly prohibited.
2.The horizontal height difference of kickboards should not exceed 1m, and the distance from the slope edge should not be less than 0.5m.
3.Longitudinal kickboards should be fixed to the uprights no more than 200mm above the footing using right-angle couplers.
4.Transverse kickboards should be fixed to the uprights directly below the longitudinal kickboards using right-angle couplers.
(V) Inspection Standards for Scaffolding Main Body
1.The inspection of the scaffolding main body should be calculated based on construction requirements. For example, the spacing of uprights in ordinary scaffolding must be less than 2m, the spacing of longitudinal horizontal bars less than 1.8m, and the spacing of transverse horizontal bars less than 2m.
2.The vertical deviation of uprights should be checked based on the scaffolding height, while controlling the absolute difference.
3.When splicing uprights, except for the topmost step, all other joints must be connected using butt couplers, and the joints should be staggered.
4.The spacing of longitudinal horizontal bars should not exceed 2m and must be continuously installed.
5.Transverse horizontal bars should be installed at the intersection of uprights and longitudinal horizontal bars and must be connected to the uprights using right-angle couplers.
6.Couplers must be used appropriately during scaffolding erection. Substitution or misuse is strictly prohibited, and couplers with stripped threads or cracks must not be used in the scaffolding.
(VI) Inspection Standards for Scaffold Boards
1.After the scaffolding is erected on the construction site, scaffold boards must be fully laid and correctly connected. At corners of the scaffolding, scaffold boards should be staggered and securely tied. Uneven areas should be leveled with wooden blocks and nailed firmly.
2.Scaffold boards on the working layer should be laid flat, fully covered, and securely tied. The overhang length of scaffold boards (the end protruding 12-15cm from the wall surface) should not exceed 20cm. The spacing of horizontal bars should be set according to the purpose of the scaffolding. Scaffold boards can be laid flat or overlapped.
(VII) Inspection of Scaffolding Tie-ins
Tie-ins are divided into rigid tie-ins and flexible tie-ins. Rigid tie-ins should be used on construction sites. For scaffolding below 24m, tie-ins should be installed at intervals of 3 steps and 3 spans. For scaffolding between 24m and 50m, tie-ins should be installed at intervals of 2 steps and 3 spans.
(VIII) Inspection of Scaffolding Cross Bracing
1.For scaffolding above 24m, cross bracing must be installed at both ends of the outer side and continuously from bottom to top. For load-bearing scaffolding and special scaffolding, multiple continuous cross bracing should be installed from bottom to top. The angle between the diagonal members of the cross bracing and the ground should be 45° to 60°. The width of each cross bracing should be no less than 4 spans and no less than 6m.
2.When the scaffolding height exceeds 24m, cross bracing must be installed continuously from low to high.
(IX) Inspection of Scaffolding Access Routes
1.Scaffolding access routes are divided into hanging ladders and "Z"-shaped walkways or inclined walkways.
2.Hanging ladders must be suspended vertically from low to high, fixed every 3m vertically, and the top hook must be securely tied with #8 lead wire.
3.Access walkways must be installed at the same height as the scaffolding. The width of pedestrian walkways should be no less than 1m with a slope of 1:6. The width of material transport walkways should be no less than 1.2m with a slope of 1:3. Anti-slip strips should be spaced at 0.3m intervals with a height of approximately 3-5cm.
(X) Inspection of Fall Prevention Measures for the Scaffolding Structure
1.If safety nets need to be hung on the construction scaffolding, check whether the safety nets are flat, secure, and intact.
2.Fine mesh nets must be installed on the outer side of the construction scaffolding, and the fine mesh nets should be flat and intact.
3.Fall prevention measures must be installed every 10-15m vertically on the scaffolding. Fine mesh nets should be promptly installed on the outer side of the scaffolding. When installing safety nets on the inner side, they must be taut, and the fixing ropes of the safety nets should be tied to secure and reliable locations.
