摘要

A non-support form assembled to a lower flange of an I-shaped concrete beam is provided to install a bridge regardless of topographic conditions and to reduce the manpower and time required for dismantlement of timbering and a form. A non-support form assembled to a lower flange of an I-shaped concrete beam includes many lower support members(21) installed on a lower flange(13) of an I-shaped concrete beam(16) to put over at regular intervals in the longitudinal direction, a support member(23) and a wedge member(22) installed between two ends of the lower support member and the side of a web(14) of the I-shaped concrete beam, a height adjustment member(28) installed between the lower support members and an upper support member(29), a vertical fixing member(30) fixed vertically at two sides of the two ends of the upper and lower support members, a corner support member(26) installed to the upper part of two ends of the upper support member, and a horizontal panel(27) installed on the upper part of the corner support member installed to the two ends.
