A prestressed wale structure and a prestressed scaffolding system using the prestressed wale structure are provided to secure a construction space under the ground and to cut down on the cost of construction by prestressing a vertical pile and a wale and reducing the number of struts for supporting a vertical pile. The invention relates to a prestressed scaffolding system using a prestressed wale structure for supporting a wale with struts(20) located on two ends by installing supports(11) on appropriate parts of a wale(50), installing anchorages(12) on two ends of the wale and tensing a steel wire(13). Hereon the prestressed wale structure comprises a wale connected to the side of vertical piles(10) and attached with plural supports, an anchorage installed to the side or two ends of the wale, a steel wire fixed to the anchorage at two ends and tensed by a support having a thread to adjust the height, and a coupler(70) coupled to the steel wire to apply prestressing force. |
