Basic study about Geometric feasibility Analysis of the System form for the Bridge Slab

교량 상판 콘크리트 타설용 거푸집 시스템의 기하학적 타당성 분석의 기초연구

The concrete work of bridge decks is performed in a high place, which may reduce safety and productivity. In addition, the conventional method for deck forms require a great deal of manpower, and a form (sheathing) board is damaged when removed after curing. As a result, the concrete deck work of bridge construction becomes the cause of delayed construction and increased cost. To solve these problems, SMART form, a system form, is developed. SMART form is a temporary device for easier installation and removal, by mounting it to the lower flange of a bridge girder and using a mechanical behavior of the form system for deck concrete pouring. For stable installation and removal of the developed SMART form, geometric behaviors should be analyzed to prove its validity. Furthermore, the validity of geometric behaviors when the SMART form size is altered in response to the various arrangement of bridge girders should be proved. Thus, the study is intended to analyze the geometric validity of the form system for bridge deck concrete pouring. The structural stability of the form system for bridge deck concrete pouring can be secured, which will be applied in the field.
