Abstract:

There are a number of construction methods to build spatial structures such as erection method, the element method, the block method, the sliding method, the lift-up method and the push-up method. These methods are uneconomical and low accuracy, and require long construction duration because of a need of a scaffold or a tower crane to build spatial roof frame. In this study, the construction method to erect a keel truss frame was proposed an economical and easy installation method. The proposed method has end hinges of keel trusses and winches with horizontal. This method makes safe and accurate production and reduces construction duration because trusses are built on the floor or supporter. The purpose of this study is to verify the validity of construction method by building scale model using the proposed method. As the erection was completed safely and simply within a short time with no special difficulties, the experiment showed that the proposed method is very effective for the erection of spatial structures composed of keel trusses.
