PURPOSE:To improve efficiency of test by projecting a jig engaged to a test piece in an atmospheric chamber, to the outside of the chamber along a load rod, clamping the test piece the axial direction between the load rod and the jig, and fixing the test piece and the load rod in the chamber. CONSTITUTION:In a heating furnance 2, each sleeve 4H, 4L are engaged to a screw threads 1a, and projected to the outside of the heating furnace 2 along each load rod 3H, 3L. Each bolt 5 is provided on the outside of the heating furnace 2, inserted into a through-hole of a flange 6 of each sleeve 4H, 4L and each load rod 3H, 3L, and a test piece 1 is clamped in the axial direction between the load rod and the sleeve by screwing a nut 7. When the part between the load rod and the test piece is loosened by an influence of heat, the test piece 1 can be fixed without taking it out of the heating furnace 2 by operating the nut 7. |
