に沿つて軸方向に移動させればよい。(B) Prior Art For example, in order to conduct a high-temperature atmosphere material test on a test piece in a vacuum atmosphere, the test piece may be housed in a furnace core tube of a heating furnace. Furthermore, a pair of load rods are inserted into the furnace core tube, and the jig of each load rod is engaged with the test piece. Then, a vacuum atmosphere is created in the furnace core tube, and the test piece is heated to a high temperature in a heating furnace. At the same time, by applying a test load to the test piece using the jig of each load rod, the test piece can be subjected to a high temperature atmosphere material test in a vacuum atmosphere. Furthermore, if an inert gas is introduced into the furnace core tube of the heating furnace to create an inert gas atmosphere, the test piece can be subjected to a high-temperature atmosphere material test in the inert gas atmosphere. After the test, the test piece can be replaced by simply moving the furnace core tube axially along the load rod.
This allows the load rod jig and test piece to be exposed to the outside. Therefore, the test piece can be replaced. The same applies when replacing the load rod jig, and the furnace core tube may be moved in the axial direction along the load rod.

悪いという問題もあつた。 Conventionally, in this type of testing device, an integral furnace core tube that is longer than the heating furnace has been used, and both ends of the furnace core tube have been made to protrude outside the heating furnace. Both ends of the furnace core tube were cooled with water so that the sealing material would not heat the ends of the furnace core tube. Therefore, when replacing the test piece and fixture after the test, the furnace core tube is moved axially along the load rod to expose the load rod's fixture and test piece to the outside.
It was necessary to make the load rod longer than the furnace core tube. For this reason, there was a problem in that the load rod could not be centered accurately and the test load could not be applied accurately to the test piece. When applying a test load to the test piece, there was a risk that the load rod would buckle due to the test load. Furthermore, when replacing the test piece and the jig, it is not easy to move the long, integrated furnace core tube in the axial direction, resulting in poor workability.

Of these two parts, an outwardly tapered surface 10L is formed at the divided end of the lower part 3L. Further, an inwardly tapered surface 10H is formed at the divided end of the upper portion 3H, and the tapered surfaces 10H and 10L of each portion 3H and 3L are fitted in the axial direction. Thereby, the divided ends of each portion 3H, 3L are separably connected. Each part 3 of the furnace core tube 3

させることができる。 Further, when the test piece 1 is heated by the heating furnace 2, the furnace core tube 3 is also heated to a high temperature, but the furnace core tube 3 is molded from ceramics and can withstand extremely high temperatures. Therefore, it is also possible to perform an ultra-high temperature material test by heating the test piece 1 made of ceramics to an ultra-high temperature. Furthermore, when the furnace core tube 3 is heated, each portion 3H, 3L of the furnace core tube 3 slightly expands thermally, but the coefficient of thermal expansion of the lower portion 3L is higher than that of the upper portion 3H. . Therefore,
When each portion 3H, 3L thermally expands in the radial direction, the tapered surface 10L of the lower portion 3L is pressed against the tapered surface 10H of the upper portion 3H, thereby sealing between the divided ends of each portion 3H, 3L.

場合も同様である。 To replace the test piece 1 after the test, the heating furnace 2 is opened, closed, or moved to expose the furnace core tube 3 to the outside. Then, the upper and lower two parts 3H, 3 of the furnace core tube 3
One portion of L may be moved in the axial direction along the load rods 4H and 4L. For example, the upper portion 3H is moved axially along the upper load rod 4H and raised. This allows the jigs 11H, 11L of the load rods 4H, 4L and the test piece 1 to be exposed to the outside. Therefore, the test piece 1 can be replaced. The same applies when replacing the jigs 11H and 11L of the load rods 4H and 4L.
