Development and Application of FCF Construction Method

The FCF construction method (Fast Failsafe Climbing Form) with the climbing robot jack as a nucleus, was developed for construction of high rise concrete structures, such as a tower-shape or a cylindrical tall bridge pier, etc. This construction method uses a plural number of the climbing robot jacks to ascend the whole of the various construction facilities assembled on the main frame for construction of a structure and descends it to the ground surface after completion of the the structure. The main features of the construction method include (1) improvement of safety (2) shortening of construction period and (3) cost reduction. Thus far this method has been introduced to 7 construction sites (12 construction objects) mainly with the aim of construction of tall bridge pier, obtaining favorable results.

As this construction methos was advanced further this time to make the working space an all-weather type and by giving various added values thereto we have constructed a chimney of RC construction with 118m in height, a high rise structure. In the text of this report, special features of this system, detailed results of construction of each component system as well as the effectiveness of application of this construction method to the high-rise structure, are described.
