Ltd.Nanchang Jiangxi 330046 China) Abstract:In the construction of Zhongting Square in Ganzhou an innovative method was proposed for the construction of beam transfer floor using pre-stressed oblique tensioning link.By properly setting pre- stressed oblique tensioning links which worked together with the concrete frame beams and columns a posite structure was formed to bear the loads of transfer beam during construction.This construction technique improves the bearing capacity of frame beam during the construction period reduces the number of supports required below the beam transfer floor and shortens the construction period.
