上記の把持体１５，１５１，１６，１７を備えた水平継
手溶接用治具は上述の如き、構造上の特徴より、前述の
（１），（２），（３），（４）の各利点に加え、さら
に次の如き利点をもたらすこととなる。The horizontal joint welding jig equipped with the above-mentioned gripping bodies 15, 151, 16, and 17 has each of the above-mentioned (1), (2), (3), and (4) due to its structural characteristics. In addition to these advantages, it also brings about the following advantages:
（５）把持体１５，１５′，１６，１７と棒鋼との接触
は線接触（もしくは複数の点接触）であるため、面接触
による把持に比較し、小さな把持力で、より確実に棒鋼
を固定することができる。(5) Since the contact between the gripping bodies 15, 15', 16, and 17 and the steel bar is line contact (or multiple point contact), the steel bar can be held more reliably with a smaller gripping force than gripping by surface contact. Can be fixed.
（６）把持体１５，１５１，１６．１７が存在するため

て棒鋼を固定させることができるので、溶接口４の中心
を鉛直軸に対し、常に約１００以内の位置でセツテイン
グすることができる。(6) Since the gripping bodies 15, 151, 16, and 17 are present, the rib portion of the steel bar can be shifted from the gripping body, and the parts other than the ribs can be brought into contact with the gripping body and gripped. (
When the gripping part of the steel bar that is missing in the gripping part is surface contact,
Because the ribs are protruding on the surface of the steel bar, the gap between the outer periphery of the steel bar and the copper dowel is not constant, resulting in the disadvantage that too much slag escapes during welding. (7) Due to the presence of the gripping bodies 15, 15'', 16, and 17, the outer periphery of the steel bar can be easily moved by slightly shifting the rib portion of the steel bar from the gripping body. Since the steel bar can be fixed with a constant gap between the welding hole and the copper dowel, the center of the weld opening 4 can always be set at a position within about 100 degrees with respect to the vertical axis.
