Requirement Analysis of the System Form for the Bridge Slab

교량 상판(바닥판) 콘크리트 타설용 시스템 거푸집 개발을 위한 요구조건 분석

Unlike general construction works, bridge construction is mostly done in a high place. The conventional deck form of bridge is installed between precast concrete girders using sleepers, bridging joints and plywoods, and after concrete is poured to the deck, the form materials are removed at high altitudes. When removing the form, it may be dropped on ground, damaging the materials and resulting in economic loss. In addition, safety accidents are likely as the works are performed in a high place, and as the manpower increases, the cost increases. Also, it is difficult to install and remove temporary equipment. Therefore, it is required to develop a system form that allows easier and quicker installation and removal by unskilled workers and ensures safety of workers. In this regard, the study is intended to analyze requirements for the system form for pouring concrete to bridge decks, which can be easily installed and removed. The study result will be used as basic information for development of the system form for pouring concrete to bridge decks.
