What safety precautions need to be done for scaffolding

1. The material specifications and support standards of scaffolding should strictly implement the relevant provisions in the "Safety Technical Regulations for Construction and Installation Engineering", and the scaffolding structure must be firm and stable.

2. Before all kinds of scaffolding are put into use, the person in charge of the construction must organize the erection and use of the scaffolding and the safety officer to jointly inspect, perform the handover and acceptance procedures, use new and self-made tools, and must have a factory certificate and assembly instructions, which can only be used after being identified by the superior safety technology department and approved and approved.

3. During the construction period, when using scaffolding above 3m, a firm protective railing must be set on the outside of the working face, and a 13cm high sail slow riser should be set up, a protective net should be set up without a foot guard, the scaffold should be more than 1m higher than the parapet wall, the slope roof exceeds the cornice, and the part above the roof should be tied with a protective railing and other protective measures.

4. The vertical rod of the steel pipe scaffold should be placed vertically and stably on the metal base or skid, the spacing between the vertical rods shall not be greater than 2m, the spacing of large crossbars shall not be greater than, and the spacing of small crossbars shall not be less than.

5. Every 10m of scaffolding pole foundation must be tamped and smooth.

6. Every 10m steel pipe scaffold pole must be provided with a base and skids.

7. Scissors and struts should be set at both ends of the scaffolding, corners and every 6 7 poles, scissors braces and struts and the angle between the ground and the ground should not be more than 60 degrees, the bottom end of the strut should be buried in the ground not less than 30cm, and when the height of the shelf is more than 7m or the strut cannot be set up, every 4m high and every 1m horizontally, the scaffold must be firmly connected with the building.

8. The ramp and platform on the outside of the scaffold should be tied with a 1m high protective railing and a nail-high foot board with a protective vertical net.

9. At the openings of doors and windows, erect oblique rods against the pick-up frame, and a section of the wall is not more than 30 degrees, and should be supported in the firm part of the building.

10. The thickness of the bamboo foot board shall not be less than 5cm, the spiral hole shall not be greater than 1m, the bolt must be tightened, the length is generally to, and the width is 30cm.

11. The width of the shelf shall not be less than, the scaffold board shall be fully paved, and the distance from the wall shall not be greater than 20cm, and a double row of small crossbars shall be erected when the head is connected, and the spacing shall not be greater than 20cm.

12. The scaffold should be a steel pipe with an outer diameter of 48 51cm and a wall thickness of 3.

13. Scaffolding safety net protection, see the organizational design of safety net erection for details.

<>What is the specific content of scaffolding protection safety measures, the following Zhongda Consulting will answer for you.

1. The steel pipe scaffolding is made of steel pipe with an outer diameter of 48 51mm, a wall thickness of 3, and no serious rust, bending, flattening or cracking.

2. The rod connections of the steel pipe scaffold are all qualified Margang fasteners, and steel wires or other materials shall not be used for binding.

3. The spacing of the vertical rods of the structural scaffold is not greater than that of the passenger transport, the spacing of the large crossbars is not greater than that of the large crossbars, and the spacing of the small crossbars is not more than 1m. When decorating, the scaffolding pole is not larger, the spacing of large crossbars is not greater, and the spacing of small crossbars is not greater.

4. The scaffold is firmly connected to the structure according to the layer, the vertical distance of the pull joint is not more than 4m, the horizontal distance is more than 6m, the strength of the material used in the pull joint is not lower than the strength of the double-strand No. 8 steel wire, and the high-rise frame does not use flexible materials for pulling the joint, and according to the current situation, a reliable support is set at the pull joint.

5. The operating surface of the scaffold is covered with qualified scaffolding, and the distance from the wall is controlled within 200mm, without gaps, probe boards and flying springboards. The lower layer of the scaffold board is provided with a horizontal net, and two protective fences and a foot guard are set on the outside of the operating surface, and the safety net is hung vertically, and the lower mouth is tightly sealed, and the protective height is not less than 1m.

6. To ensure that the overall structure of the scaffold is not deformed, where the height of the scaffold is more than 20m, the longitudinal scissor brace is arranged, the width of which is not more than 7 vertical rods, the angle between the scaffold and the horizontal plane is controlled at 450 600, and the height is below 20m, and the positive and negative oblique supports are set.

7. Draw up the design scheme of special scaffolding and tall scaffolding with a height of more than 20m.

8. The load of the internal and external load-bearing scaffolding used in the structure shall not exceed 2646n m2. The use load of the interior and exterior scaffolding for decoration does not exceed 1960N.

9. The horizontal and vertical distance between the outer edge of the construction in progress (including scaffolding with ballast ear frame) and the edge of the external power overhead line shall not be less than 3m.

10. Before all kinds of scaffolding are put into use, the person in charge of the construction shall organize the person in charge of supporting and using the scaffolding, as well as the technical and safety personnel to conduct joint inspection and acceptance, and perform the inspection procedures.

11. Before the special scaffold is erected and disassembled, the technical department shall prepare a safety construction plan and submit it to the superior technical leader for approval before construction.
