MULTICRAB - TECHNICAL INFORMATION - 2023 78 ANCHORS AND ANCHOR POINTS ANCHORS The anchor transmits horizontal and vertical forces on the scaffolding to the anchoring. The anchoring points are placed on the structure to stabilise the scaffolding on it. Anchors and anchoring points form an assembly that secures the scaffolding to the structure in front of it. They must on no account be dismantled while the scaffolding is in use. Anchors are important for the stability of the scaffolding. They must be sized, distributed and executed with care. They withstand tensile and compressive forces and must always be installed at right angles to a node using scaffolding couplers. Depending on the structure, make sure that the anchors bear the forces. On no account should the resistance of an anchor be less than 300 daN. For bearing horizontal forces parallel to the façade, the anchor tube must be fixed to the inner and outer standards. Allow for plane wind bracing of the anchors when the structure is more than 0.40 m from the building. NUMBER AND ARRANGEMENT OF THE ANCHORS For façade scaffolding under 24.00 metres tall, the following arrangements are recommended in NF conditions of use. Non-covered scaffolding Theoretically: In practice: Anchoring every 4.00 m for the 2 end sides,anchoring every 8.00 m for the middle sides, with staggered assembly in order to have better distribution. Density of the anchors distributed on a largesize façade: at least 1 every 24 m2 (excluding end sides). Covered scaffolding (with a canvas cover or equipped with nets) Theoretically: In practice: Anchors every 4.00 m for all sides with staggered assembly for better distribution. Density of the anchors distributed on a largesize façade: at least 1 every 12 m2 (excluding end sides). The canvas covers or nets must fully cover the scaffolding, including the returns. In that case, the anchors can be subject to high forces. = Anchor points = Anchor points
