<P>PROBLEM TO BE SOLVED: To apply a tensile load which is straight in a radial direction and free of disturbances such as vibration and deviation so as to create an ideal destruction state to a test body and pulling the test body straight in the radial direction. <P>SOLUTION: An apparatus includes a center guide 2c inserted into a center hole 11a of a test body 11 and provided with an anchor block 2d at a lower end thereof which is fixed to the bottom of the center hole 11a; a pressure plate 4 penetrated by the center guide 2c to be placed on an upper surface of the test body 11 and with a lower surface thereof adhered to the upper surface of the test body 11; a load measuring means 3 mounted to an upper surface of the pressure plate 4; a tensile load application means 2 disposed above the load measuring means 3 and fixedly mounted to a position close to an upper end of the center guide 2c; and a guide mechanism 7A interposed between and among the center guide 2c and a piston 2b of the tensile load application means 2, the load measuring means 3, and the pressure plate 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
