About the control points of scaffolding erection

Scaffolding is a framework for workers to work at high places. If the erection process is careless and the connection is not strong, The later construction is prone to problems. The following Hubei Wangke Formwork Co., Ltd. will take you to take stock of the control points that should not be underestimated in the scaffolding erection.

1. The beam slab on a circular curve with a small radius, the scaffolding layout is based on the design principle , Adjust according to the actual construction situation. When the number of small crossbars does not meet the construction requirements, use Ф48mm steel pipes and fasteners instead, and it is strictly forbidden to cancel the small crossbars.

2. After the scaffolding is erected, its plane position, top elevation, node connection and vertical and horizontal stability Perform a comprehensive inspection. Before concrete pouring, tighten the upper and lower brackets of the scaffold to ensure close contact with the square timber to prevent the settlement and deformation of the scaffold during the concrete pouring process.

3. The tightening torque of fastener bolts after installation should be checked by a torque wrench, and the sampling method should be randomly distributed In principle. The tightening torque of fastener bolts shall not be less than 40kN·m and not more than 60kN·m.

4. Set construction joints at both ends of the segmented pouring, and remove the bottom bracket after the middle section is stretched and grouted. Scaffolding, but the support system at the end of the cantilever shall not be removed before the construction of the entire beam section is completed.

5. Lightning protection grounding: The scaffolding with a height of more than 20m must be grounded for lightning protection.

6. Power cord: When the power cord contacts the frame, use a hook with an insulating sleeve. The distance from the overhead transmission line shall not be less than 3 meters.

7. Bracket scaffolding should use professional tools: use a spirit level to correct the vertical pole sag and horizontal pole ; Use a meter ruler to control the step distance, vertical distance and horizontal distance.

8. The rods and springboards at the end of the frame should not be larger than 20cm, and the probe length should be uniform.

9. The transmission material shall not damage the dense mesh network.

10. The scaffolding specification for the cable wind rope stipulates that the full house scaffold and the full house support frame are installed during the installation process. Temporary fixing measures should be taken to prevent overturning.
