COMPOSITE GIRDER WITH STEEL TRUSS WEB AND CONNECTION STRUCTURE THEREOF

摘要

A composite belly trust girder with an allowable displacement connection structure due to a slip plate and a panel point connection structure thereof are provided to improve a field assembling property of upper and lower flanges and a diagonal member by burying the diagonal member in the upper and lower flanges in the field. A composite belly trust girder includes a belly. The belly is formed in a truss structure of a diagonal member(1). The diagonal member includes an upper flange, a lower flange, and a steel material. Slit plates(2) are formed at a connection end of the belly. A slit(3) is formed in the slip plate. Before the connection end of the belly is buried in the upper flange or the lower flange, the slit plates are disposed to be overlapped with each other. In a state that a horizontal movement and a connection angle between the bellies are adjusted, the diagonal member is connected by a coupling member(4), which penetrates the slit.
