PURPOSE: To reduce the cost, and to effect the miniaturization by using a light metal head to receive the generated force under an optimum condition for a light metal support locking member, and welding it to a U-shaped light metal member. CONSTITUTION: Stays 20 support a perforated plate 21 with intervals corresponding to the lattice dimension of a scaffolding, a support locking member 22 is fixed between two stays 20, and a scaffolding plate 23 is supported by the support locking member 22. A hooking claw 24 is provided on an end part of the scaffolding plate 23, and supported by a support edge 25 of a U-shaped member 26 of the support locking member 22. A connection head 30 is manufactured of a light metal by an appropriate casting method, and the shape of a detailed part is determined according to the stress and the strength of the light metal. The connection head 30 is of standard structure on the whole. |
