Development of Automatic Exterior Precast Concrete Wall Panel Construction System

This automatic exterior precast concrete wall panel installation system performs a series of in-situ construction work, from spraying paint on exterior precast concrete wall panels, to transporting and installing them. The system consists of an automatic exterior precast concrete wall panel paint spraying system, an automatic transportation system and an automatic installation system, and, during work is underway, is intensively controlled through a control station located in a field office in order to ensure the system’s uninterrupted operation, safety, line balance, as well as the registration of work completed or in progress, and the issue of commands.This paper first introduces, as a development example, how the system in question was applied to the construction of the exterior walls of a 13-storied building located at a minimal possible lot in a populated urban area, a project which triggered off the system development. Then the evolution of the system development, the method of system design, the characteristics of the system, the summary of the equipment incorporated, and the results of the system’s application to the above mentioned building project will be described.
