External wall hole of traditional cantilever scaffold

Cantilever scaffolding is a right-hand man in the construction site, but safety is always the first. Let's have a deep understanding of this important specification of 10 meter limit, so that you can feel at home in the field of architecture.

Careful selection of materials

We recommend the use of biaxial symmetric steel (I-beam) with a height not less than 160mm as the cantilever beam structure. Ensure the accuracy of the anchor point, which is not less than 100mm from the end of the cantilever beam. The anchor point shall be made of steel bars or short pipes with a length of 0.2m and a diameter of 25-30mm. The length of the fixed end should be 1.25 times greater than the length of the cantilever end, and the spacing of the cantilever beam should match the vertical distance of the vertical pole of the cantilever frame, so as to ensure one for each vertical distance.

Safety net protection device

The outer side of scaffold should be covered with dense mesh safety net. Conditional to use blue dense mesh safety net to achieve full closure. In the installation and decoration construction stage, a layer of scaffolding shall be laid vertically every 12m on the external scaffold, and a horizontal safety net shall be hung on the middle layer, which must be fixed on the building structure.

Structural corner

At the corner of the building structure, steel beams should be arranged in a fan shape. If there are too many steel bars at the corners of the structure to leave holes, reinforcement measures such as welding steel tripods with embedded parts can be considered. At the same time, the supporting point of cantilever steel beam should be set on the structural beam, avoiding setting on the cantilever balcony or cantilever plate, otherwise corresponding reinforcement measures should be taken.
