SHEAR CONNECTOR USED IN PROCESS OF INCREASING THICKNESS OF CONCRETE WALL, AND PROCESS OF INCREASING THICKNESS OF CONCRETE WALL

摘要

PROBLEM TO BE SOLVED: To eliminate such a problem in a conventional process of increasing a wall thickness of a concrete wall that several anchoring holes each for planting, in the concrete wall, a shear connector and a separator through an anchor are respectively formed so as to make the process is laborious. ;SOLUTION: A shear connector 1 is planted in an existing concrete wall 40 by engaging a male thread part of a separator with a male thread part of each of anchoring holes formed in the concrete wall 40 at predetermined intervals, through an anchor 31. After the separator 21 for the shear connector 1 is threadedly engaged in the anchoring hole, a form 44 is assembled and thereafter, a Form Tie (registered trade mark) is connected to the separator before the form 44 is fastened. Finally, concrete is placed between the concrete wall 40 and the form 44.;COPYRIGHT: (C)1998,JPO
