Scaffolding acceptance points

When to accept
(1) After the foundation is completed and before the scaffolding is erected;
(2) After every 10~13m height is erected;
(3) After reaching the design height;
(4) Before applying the load on the working layer;
(5) After encountering sixth-level strong wind and heavy rain; after freezing in cold areas;
(6) Disable for more than one month.

Acceptance of scaffolding foundation and foundation: According to the relevant regulations and the soil conditions of the erection site, the construction of the scaffolding foundation and foundation shall be carried out after calculating the height of the scaffolding that must be erected, and checking whether the scaffolding foundation and foundation are compacted and flat and whether there is water accumulation.

Acceptance of the drainage ditch of the scaffolding body: The scaffolding site should be flat and free of debris, which can meet the requirements of unobstructed drainage. The width of the upper opening of the drainage ditch is 300mm, the width of the lower opening is 180mm, the width is 200~350mm, the depth is 150~300mm, and the slope is 0.5.

Acceptance of scaffolding pads and bottom brackets: This acceptance should be carried out according to the height and load of the scaffolding. For scaffolds with a height of less than 24m, a pad with a width greater than 200mm and a thickness greater than 50mm should be used, and it should be ensured that each pole must be placed on the pad. The middle part and the area of ​​the backing plate shall not be less than 0.15㎡. The thickness of the bottom plate of the load-bearing scaffold with a height of more than 24m must be strictly calculated.

Acceptance of the scaffolding sweeping pole: the horizontal height difference of the sweeping pole shall not be greater than 1m, and the distance from the slope shall not be less than 0.5m. The sweeping pole must be connected with the vertical pole, and the direct connection between the sweeping pole and the sweeping pole is strictly prohibited.

Acceptance of scaffolding main body:
(1) The distance between the vertical poles of ordinary scaffolding must be less than 2m, the distance between the large crossbars must be less than 1.8m, and the distance between the small crossbars must be less than 2m. acceptance. A load of general scaffolding shall not be greater than 300kg/㎡, and special scaffolding shall be calculated separately. The scaffolding carried by the building shall be checked and accepted according to the calculation requirements. There can be no more than two working faces within the same span.
(2) The vertical deviation of the pole should be checked and accepted according to the height of the frame, and the difference should be controlled at the same time, that is, when the height of the pole is lower than 20m, the deviation of the pole should not be greater than 5cm. When the height is between 20 and 50m, the deviation of the pole is not more than 7.5cm. When the height is greater than 50m, the deviation of the pole shall not be greater than 10cm.
(3) In addition to lap joints at the top of the top layer, the joints of the other layers and steps must be connected to the scaffolding body using butt fasteners. The joints should be arranged in a staggered manner. In the double pole scaffold, the height of the auxiliary pole shall not be less than 3 steps, and the length of the steel pipe shall not be less than 6m.
(4) The large crossbar of the scaffold shall not be larger than 2m and must be set continuously. The small crossbar of the scaffold shall be set at the intersection of the vertical bar and the large horizontal bar and must be connected with the vertical bar by right-angle fasteners.
(5) The fasteners must be used reasonably in the process of erecting the frame body, and the fasteners shall not be replaced or misused, and the fasteners with sliding wires or cracks shall not be used in the frame body.

Acceptance of scaffolding:
(1) The scaffolding on the construction site must be fully laid, and the scaffolding must be connected correctly. At the corners of the scaffold, the scaffolding should be staggered and lapped and must be fastened, and the unevenness should be flattened with wooden blocks.
(2) The scaffolding on the working layer should be flat, covered tightly, and tied firmly. The length of the probe of the scaffolding at the end of 12~15cm away from the wall should not be greater than 20cm. The laying of hand board can be used for butt laying or lap laying.

Acceptance of scaffolding scissor braces: When the height of the scaffolding is greater than 24m, a pair of scissor braces shall be continuously installed at both ends of the outer facade from the bottom to the top, and shall be installed. The load-bearing and special shelves are equipped with multiple continuous scissor braces from bottom to top. Whether the inclination angle of the diagonal bar of the scissor brace and the ground is between 45° and 60°, the width of each scissor brace should not be less than 4 spans, and should not be less than 6m.

Acceptance of scaffolding up and down measures: Ladder hanging must be set vertically from low to high, about 3 meters to be fixed once, and the top hook should be firmly tied with No. 8 lead wire. There are two types of scaffolding up and down measures: hanging ladders and erecting “Zhi” shaped walkways or inclined walkways. The upper and lower walkways must be erected together with the height of the scaffolding. The slope of the walkway is 1:6 and the width shall not be less than 1m. The slope of the material transport walkway shall be 1:3 and the width shall not be less than 1.2m. The distance between the anti-skid strips is 0.3m and the height is 3~5cm.

Acceptance of anti-fall measures for the frame body: anti-fall measures should be set up every 10~15m in the vertical height of the scaffold, and a dense mesh should be set up on the outside of the frame body in time. When laying the inner safety net, it must be tightened, and the safety net fixing rope must be wrapped around and tied in a reliable place.
