<P>PROBLEM TO BE SOLVED: To provide an effective and appropriate block joint capable of connecting various block frames such as segments with each other by a single operation; and a block frame to be connected by the block joint. <P>SOLUTION: Block joints 2(2A,2B) with a fitting part installed in both joint end surfaces of a pair of block frames (segment 1A,1B) and for sliding the mutual joint end surfaces in a single direction so as to fit and join them mutually comprises the fitting part and a fixing part. The fitting part is extended in a sliding direction of the block frame while the fitting part has the same cross section in the sliding direction, and a fitting part shaft in an extended direction of the fitting part is disposed in a tilting state so as to approach the side of the other block frame as the block frame moves toward the sliding direction relative to the other block frame. The fitting part is the fitting part of a linear steel sheet pile and the fixing part is a plate part of the linear steel sheet pile. The intermediate part of the fixing part is shaped in a folding form. <P>COPYRIGHT: (C)2012,JPO&INPIT |
