位置調整装置に関する。Detailed Description of the Invention [Industrial Field of Application] The present invention is an enclosure welding method in which a pair of rod-shaped materials to be welded, such as reinforcing bars, are vertically erected or horizontally enclosed and welded, and the present invention relates to double-wave welding. The present invention relates to a welding position adjustment device that adjusts the position of materials.

も同様に鉄筋の軸方向にその接合面を移動させて開先間
隔を調整する必要がある。[Prior art] Rebars embedded in concrete columns of reinforced concrete buildings are either connected one by one at the construction site, or
Alternatively, multiple reinforcing bars are placed two-dimensionally within the cross-sectional area of a column in a factory or on the ground, stacked on top of each other on a construction site, and the stacked assemblies are welded together in a vertical position. They are joined using the pre-assembly method, etc. In any case, a pair of reinforcing bars are arranged coaxially with a predetermined groove space between their joint surfaces, and a U-shaped abutment, for example, is provided so as to surround this groove space. A welding rod is inserted through the opening at the tip of the welding rod to form an arc in the groove space, thereby filling the groove space with weld metal and joining the reinforcing bars. In this case, the reinforcing bars are often displaced from coaxial positions, and therefore it is necessary to forcibly correct both reinforcing bars to coaxial positions using a position adjustment device. Further, even if the groove spacing of the reinforcing bar deviates from a predetermined range, it is necessary to similarly adjust the groove spacing by moving the joint surface in the axial direction of the reinforcing bar.

の状態で内筒と外筒とを固定して鉄筋を配置する。In the conventional position adjustment device, an outer cylinder and an inner cylinder extending in the longitudinal direction of a pair of rod-shaped reinforcing bars are fitted together and are slidable in the longitudinal direction and circumferential direction. It is constructed by fixing gripping members for gripping reinforcing bars to the outer cylinder and the inner cylinder, respectively (Utokosho [No. 1O-84183]). Then, one gripping member is attached to one of the reinforcing bars, the other gripping member is attached to the other reinforcing bar, and the groove spacing of the reinforcing bars is adjusted by sliding the outer cylinder and the inner cylinder in their axial directions. Further, by relatively rotating the outer cylinder and the inner cylinder in the circumferential direction thereof, and rotating both reinforcing bars about the axes of the inner cylinder and the outer cylinder so that they are coaxial with each other, The inner cylinder and outer cylinder are forcibly bent, the inner cylinder and the outer cylinder are fixed in this state, and reinforcing bars are placed.
［発明が解決しようとする課題］
しかしながら、上述した従来の位置調整装置は、鉄筋の
位置調整が可能な方向が鉄筋の長手方向か又は内筒及び
外筒を中心として回転する方向である。即ち、第４図に

８又は０２を中心とする半径ｒの円周上の位置にのみ調
整することができる。[Problems to be Solved by the Invention] However, in the conventional position adjustment device described above, the direction in which the position of the reinforcing bars can be adjusted is the longitudinal direction of the reinforcing bars or the direction in which the reinforcing bars rotate around the inner cylinder and the outer cylinder. That is, as shown in FIG. 4, if the position between the lower reinforcing bar 1 and the upper reinforcing bar 2 is misaligned, The reinforcing bars 1 and 2 are rotated in a direction in which they approach each other. However, r is the distance between the axes (01 or 02) of the inner cylinder and the outer cylinder and the axis of the reinforcing bar 1°2 held by the gripping member, and therefore becomes the turning radius of the reinforcing bar. In this way, the reinforcing bars 1 and 2 are placed at the axial center O of the inner cylinder and outer cylinder.
It can only be adjusted to positions on the circumference of radius r centered at 8 or 02.
しかしながら、先組み工法の梁及び柱等のように、鉄筋

装置を設置することが不可能になる。However, when the reinforcing bars are set close to the minimum spacing, such as in beams and columns of pre-assembled construction, the space in which the position adjustment device can be installed is severely restricted. For example, as shown in Fig. 4, when trying to align reinforcing bars 1°2, the positions (
01 or 02), it becomes impossible to install the position adjustment device.
本発明はかかる問題点に鑑みてなされたものであって、
被溶接物の位置調整可能領域が拡大され、所謂過密配筋
