STEEL FRAME REINFORCED CONCRETE SEGMENT

摘要

PROBLEM TO BE SOLVED: To very simply connect a piece joint metal fixture to a reinforcing steel frame in SRC segment such as for tunnel lining or the like without using the conventional high strength bolt, completely eliminate specially strict accuracy control in the case a steel frame section is manufactured and to reduce a manufacturing cost. SOLUTION: In an SRC segment formed by setting a plurality of reinforcing steel frame materials 3 and a piece joint metal fixture (female type hardware) 4 for connecting the neighboring segment pieces 1 to each other, the piece joint metal fixture 4 is constituted of a joint section 6 located between a pair of right and left reinforcing steel frame materials 3 and an interlock section 7 projecting in the direction of the width of the segment piece 1 from the opposite joint surface side of the joint section 6, a load transferring material 8 capable of preventing the separation to the joint surface side of the interlock section 7 is provided to the arc directional ends of the reinforcing steel materials 3, and the reinforcing steel frame materials 3 manufactured so as to form a gap 9 between the interlock section 7 and load transferring material 8 and the piece joint metal fixture 4 are arranged in a form 11 to cast concrete 2.
