Title:
PRESTRESS STEEL WALE FOR EARTH RETAINING SCAFFOLDING AND CONSTRUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/008657
Kind Code:
A1
Abstract:
Provided are a prestress steel wale for earth retaining scaffolding and a construction method thereof, wherein a PS steel fixed bracket and a PS steel base, which are used in the existing steel wale for earth retaining scaffolding, are improved so as to increase the amount of induced prestress by the PS steel material, simplify the induction of additional prestress during construction, and prevent the buckling displacement of the PS steel base when inducing the prestress, thereby improves constructability, increases stability, makes it possible to have extending span ranges and increases economic efficiency. According to the prestress steel wale for earth retaining scaffolding and the construction method thereof, a PS steel fixed bracket and a PS steel base, which are used in the existing steel wale for earth retaining scaffolding are improved so that the amount of induced prestress by the PS steel material is increased, the additional prestress makes it possible to be induced at any time during the construction, and the buckling displacement of the PS steel base is prevented when inducing the prestress. Therefore, it is possible to improve constructability, increase stability, promote extending span ranges and improve economic efficiency.
