与えるので、試験精度の低下を招く欠点がある。In high-temperature tensile equipment, it is not necessary to install the load application mechanism for the test piece and the pressure sealing mechanism installed in the high-temperature chamber on the low-temperature side; instead, there is always a shaft between the mechanism and the high-temperature chamber. There are parts where there is a temperature difference in the direction. In this case, when the high temperature portion is located below and the low temperature portion is located above, convection occurs in the fluid surrounding the temperature difference portion, and this convection thermally deforms the temperature difference portion over time. This thermal deformation has a negative effect on the stress added to the test piece and the elongation of the test piece, resulting in a reduction in test accuracy.

A foreign material 13 is inserted into the gap between the lower end of the cover 3 and the lid 3. As this foreign material 13, for example, a stainless wool sintered member is used.
9 stainless steel wire with a diameter of 10μφ is sintered at high temperature. Since the thin wires have a structure in which they are locally bonded to each other, the thin wires are not a fragile material that does not easily peel off, and are an easy material to cut. 14 is a test piece held between one end of the pull rod 11 (lower end in the figure) and the upper end of the test piece holder 6; 15 is a sealing material attached to the top of the confining tube 9;

測定伸びは時間と共にランダムに変化し、その最大変化
量は50kg−fであった。Using a top-mounted structure (without inserting a foreign material 13 into the gap 12), 85 kg-1/c was passed from the mother loop (not shown) into the high temperature tank 1 through the connecting pipe 8a.
The high temperature bath 1 was maintained at 250C in the electric furnace 2.Then, the pull rod 11 was moved upward by a certain amount, and the test piece 14 was heated at 500 kg-f.
A load was applied to the test piece, and its change over time was measured. The results are shown in Figure 2, which shows that the measured load and elongation changed randomly over time, and the maximum amount of change was 50 kg-f.

A thermocouple 17 was connected to a temperature recorder 18 via a lead wire 19, and the temperature of the sealing tube 9 was measured.

。The measurement results are shown in Figure 4.
o to t3 are temperature distribution curves in the longitudinal direction of the sealing tube 9 at 0, 5, and 12.17 minutes, respectively. It can be seen from FIG. 4 that the temperature inside the sealing pressure tube 9 changes in a complicated manner with time. From the relationship between the fluctuation period, the measured load, and the measured elongation, the gap 1 between the confining pressure tube 9 and the pull rod 11
This is thought to be due to the intense convection phenomenon occurring within 2.
そして、熱変動に伴うプルロッド11または封圧管9の
熱変形が上記現象に反映されたものと理解される。It is understood that thermal deformation of the pull rod 11 or the sealing tube 9 due to thermal fluctuations is reflected in the above phenomenon.
そこで、本実施例では上記現象を防止するため、前述し

るようにした。Therefore, in this embodiment, in order to prevent the above phenomenon, a foreign material, that is, a stainless wool sintered member 13 is inserted into a part of the gap 12 between the sealing tube 9 and the pull rod 11 as described above, and the pull rod 11 and A gap of 0.08 m is formed between the sintered member 13 and the sintered member 13.
Even if they come into contact, the sliding resistance is about 1 kg-f.
その結果、封圧管9の外表面の温度分布は第4図の曲線

5SRT試験および疲労試験への適用が可能となる。As a result, the temperature distribution on the outer surface of the confining pressure tube 9 became gentle as shown by the curve to in FIG. 4, and no change with time was observed. Similarly measured load change is 2kg-f
The amount of change in elongation of test piece 14 was below the measurement limit. Therefore, according to this example, the accuracy of the tensile test can be improved, so that it can be applied to 5SRT tests and fatigue tests at high temperatures.

して荷重の時間変化を測定した。In the above first embodiment, a stainless wool sintered member was used as the foreign material 13, but a ring with high heat insulation properties that is movable or deformable in the axial and radial directions, for example, made of 5US304 stainless steel or Teflon, is used instead. A ring may also be used. This ring has a plate thickness of 0.2 or 0.
8 m, the gap between the ring and the pull rod is 0.4 or 0.1 trtm, and eight rings are provided in this gap in the axial direction, and the load is controlled in the same manner as in the first embodiment. Changes over time were measured.
その結果、いずれの場合でも隙間内にリングを設けるこ

果かえられた。特に板厚0.8調のテフロン製リングを
用い、このリングとプルロッドとの間の隙間を0.1閣
にした場合には、最も優れた効果かえられた。As a result, in all cases, by providing a ring within the gap, the load fluctuation was reduced to 2 kg-f or less, and an excellent effect was obtained. In particular, the most excellent effect was obtained when a Teflon ring with a thickness of 0.8 was used and the gap between the ring and the pull rod was set to 0.1.
一方、板厚0.2喘のステンレス鋼製リングを用いた場
合およびそのリングとプルロッドとの間の隙間を0.4
rranにした場合には、荷重変動は増加する傾向が認
められた。On the other hand, when using a stainless steel ring with a plate thickness of 0.2 mm, the gap between the ring and the pull rod is 0.4 mm.
When it was set to rran, it was observed that the load fluctuation tended to increase.

防止できることが判明した。According to the above results, according to this example, (1) convection is prevented from occurring in the gap between the ring and the pull rod, and (10) convection is prevented from occurring in the gap between the ring and the sealing tube. However, it has been found that the generation of convection can be prevented by making it difficult for the heat change to be transmitted to the pull rod and by reducing the gaps between the sealing tube and the pull rod.
次に他の実施例として、第1実施例(第1図)における
水冷ジャケット10の下部より高温槽ふた3の下面まで

溝20を軸方向に4個設けると共に、封圧管9の外側に
防風壁(図示せず)を設けた。その他の構造は第1実施
例と同一であるから、図面および説明を省略する。Next, as another example, the cross-sectional shape of the pull rod 11 from the lower part of the water cooling jacket 10 to the lower surface of the high temperature tank lid 3 in the first example (Fig. 1) was formed as shown in Fig. 5. That is, four grooves 20 each having a width of 4 mm and a depth of 2 mm were provided in the pull rod 11 in the axial direction, and a windbreak wall (not shown) was provided on the outside of the sealing tube 9. The rest of the structure is the same as the first embodiment, so drawings and explanations will be omitted.
このような実施例において、水温を20:l:0.2C
VC調節された水を水冷ジャケット内に流量300±2

形に対する時間依存性のないことがわかる。In such an embodiment, the water temperature is 20:1:0.2C.
Flow rate of VC-regulated water into the water cooling jacket is 300±2
When a test was conducted in the same manner as in the first example by supplying ml/min, the load fluctuation was 2 to 4 kg, f. In this case, the temperature at the outer periphery of the confining pressure tube is the fourth in the axial direction.
As shown by curve 1o in the figure, it changes gently,
In the circumferential direction, it changed to the highest and lowest values every 90 cm. In this case, a convection phenomenon is generated in the gap, but by providing a groove in the pull rod as described above, it is expected that a steady convection is generated, and the time dependence of the thermal deformation of the pull rod is expected to occur. It turns out that there isn't.
前記第1実施例は、試験片14を保持するプルロッド1
1が、高温槽1の上端面に設けた開口部1aを閉塞する
ふた3を貫通し、高温槽1の上方に位置するように構成
したが、これと逆にプルロッドが高温槽の下端面に設け
た開口部を閉塞するふたを貫通し、高温槽の下方に位置
するように構成してもよい。The first embodiment has a pull rod 1 that holds a test piece 14.
1 passes through the lid 3 that closes the opening 1a provided on the upper end surface of the high temperature tank 1, and is positioned above the high temperature tank 1.However, in contrast to this, the pull rod is inserted into the lower end surface of the high temperature tank 1. It may be constructed so that it passes through a lid that closes the provided opening and is located below the high temperature bath.
このように構成した本実施例を用い、第1実施例と同様
にして試験を行った結果、荷重変動は0.5kg−f以
下であった。また第1実施例では荷重繰返し速度を3H
2としたとき、荷重変動は0.8kg−fであるのに対
し、本実施例では依然として0.5kg−fであった。Using this example configured as described above, a test was conducted in the same manner as in the first example, and as a result, the load fluctuation was 0.5 kg-f or less. In addition, in the first embodiment, the load repetition rate was set to 3H.
2, the load variation was 0.8 kg-f, whereas in this example it was still 0.5 kg-f.
これは、高温槽を上方位置に設置することにょシ、対流
現象が原理的に発生しにく\なるばかシでなく、プルロ
ッドの移動に伴って流体が移動するのを防止できるから
である。This is not because the convection phenomenon is theoretically less likely to occur if the high temperature tank is installed in an upper position, but also because it is possible to prevent the fluid from moving as the pull rod moves.
以上説明したように本発明によれば、試験片への付加応
力および試験片の伸びの時間変動を防止し、試験精度の
