Description
【考案の詳細な説明】
本考案は複数の試験片を直列に連結する継手の改良に関
するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a joint that connects a plurality of test specimens in series.
第１図にレバ一式クリープ破断試験機の側面図を示す。FIG. 1 shows a side view of a lever complete creep rupture tester.
複数個の試験片０１は管状継手０２で接続されこれを電
気炉０３で加熱する。A plurality of test pieces 01 are connected by a tubular joint 02 and heated in an electric furnace 03.
さらに支点堆０４を支点として、レバー０５を介して、
連杆０６に重り０７を乗せると試験片０１に引張荷重が
負荷される。Furthermore, using the fulcrum deck 04 as a fulcrum, via the lever 05,
When the weight 07 is placed on the continuous rod 06, a tensile load is applied to the test piece 01.
モーター０８は、試験片が伸びてレバーに傾きが生じた
場合、ウオームギヤー０９を通じて常にレバーを水平に
保つように作動させる。When the lever is tilted due to elongation of the test piece, the motor 08 is operated through the worm gear 09 to keep the lever horizontal.
第２図に従来の試験片継手の縦断面を第３図に間部の横
断面を示す。FIG. 2 shows a longitudinal section of a conventional test piece joint, and FIG. 3 shows a cross section of the joint.
欠点として、例えば低合金鋼の試験片等のように大気中
高温で腐食され易い材料は、試験片０１の連結ネジ部が
高温長時間（１００時間以上）試験に於て酸化膨張し、
一体型の管状継手０２では、試験終了後に試験片を取り
外すことが出来なくなる。As a drawback, for materials that are easily corroded at high temperatures in the atmosphere, such as low-alloy steel test pieces, the connecting screw part of test piece 01 oxidizes and expands during long-term (100 hours or more) tests at high temperatures.
With the integrated tubular joint 02, the test piece cannot be removed after the test is completed.
本考案はこの欠点を排除するものであって、端部にネジ

継手を緊締する緊締部材とからなることを特徴とし、そ
の目的とするところは、高温中で試験片を直列に接続し
て試験を行なうための継手であって、試験完了後に試験
片を容易に取り外すことが出来るようにした継手を提供
するものである。The present invention eliminates this drawback, and is a joint that connects a plurality of test specimens each having a threaded portion at the end in series, the threaded portion engaging with the threaded portion of the test specimen. A tubular joint that is divided into two on a plane that includes the axis and has a tapered part that protrudes from both ends toward the center on the outer peripheral surface, and a joint that surrounds the joint and extends in the direction of the tapered protrusion. Its purpose is to provide a joint for testing by connecting test specimens in series at high temperatures, and to allow the test specimens to be easily removed after the test is completed. The present invention provides a joint that allows this.
以下、本考案継手を第４図および第５図に示す一実施例
について説明する。Hereinafter, an embodiment of the joint of the present invention shown in FIGS. 4 and 5 will be described.
端部にネジ部が設けられている試験片１のネジ部と係合
するネジ部を有し、軸芯を含む面で２つ割りにされてい
る管状継手２，２′は、外周面に両端から中央に向って
隆起するテーパ一部２ａ、２ａ’が形成されている。The tubular joints 2 and 2' have a threaded part that engages with the threaded part of the test specimen 1, which has a threaded part at the end, and are divided into two on the plane including the axis. Tapered portions 2a and 2a' are formed that protrude from both ends toward the center.
３および４は上記継手２，２′を囲繞し、かつテーパ隆
起方向に沿って継手を緊締する緊締部材であって、同部
材３，４同志が螺合し上記管状継手２，２′を締め付け
るものである。Numerals 3 and 4 are tightening members that surround the joints 2 and 2' and tighten the joints along the direction of the tapered protrusion, and the members 3 and 4 are screwed together to tighten the tubular joints 2 and 2'. It is something.
なお、緊締部材３，４の側面の一部には取付け、取外し
用のスパナ嵌め込み部３ ａ 、４ ａが設けられてい
る。Incidentally, a part of the side surface of the tightening members 3, 4 is provided with a spanner fitting part 3a, 4a for attachment and removal.
試験終了後は、まず緊締部材３および４のスパナ嵌め込
み部３ ａ 、４ ａにスパナをかけ互いに逆方向に回
転させ緊締部材３．４を管状継手２，２′から外す。After the test is completed, a spanner is applied to the spanner-fitting portions 3 a and 4 a of the tightening members 3 and 4, and the tightening members 3 and 4 are rotated in opposite directions to remove the tightening members 3 and 4 from the tubular joints 2 and 2'.
次に管状継手２と２′の間隙Ｈにクサビを挿入し試験片
１から取り外す。Next, a wedge is inserted into the gap H between the tubular joints 2 and 2' and removed from the test piece 1.
このように本考案の一実施例の継手によると低合金鋼等
、高温酸化し易い材料の試験完了後試験片を容易に取り
外すことが上米るようになった。As described above, according to the joint according to one embodiment of the present invention, it is now possible to easily remove a test piece after testing a material that is easily oxidized at high temperature, such as low alloy steel.
