<p><P>PROBLEM TO BE SOLVED: To provide a joint metal fitting for a screw steel rod, which is capable of surely preventing the loosening of a fixed state of a connection joint and the screw steel rod and the detachment of the screw steel rod from the connection joint, etc., even in the case of performing the work of rotating the screw steel rod connected through the connection joint in the direction of detaching it from the connection joint, is in a simple structure, and is also excellent in the workability of attachment and detachment to/from the screw steel rod. <P>SOLUTION: The joint metal fitting for the screw steel rod includes: a pipe member 20 formed in a size capable of housing therein a connection joint 10 for connecting the end parts of screw steel rods 1a and 1b which are provided with a screw part and a flat part on the outer peripheral surface and are roughly in an elliptic shape in the cross sectional view with each other; and a first turning block member 30 and a second turning block member 40 fixed to both end openings of the pipe member 20. Insertion holes 31 and 41 of the first turning block member 30 and the second turning block member 40 are formed in an elliptic shape slightly larger than the cross sectional view shape of the screw steel rods 1a and 1b so as not to rotate the screw steel rods 1a and 1b. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
