ものである。Conventionally, for example, it is constructed in the form of a portal type, a brace stiffener type, a U-shaped processed stiffener type, etc., and both sides of the pillar, or a shaft inwardly above and below one of the pillars. A crossing brace pin is attached, and a connecting pin hole is formed at the upper end of the pillar, and a connecting pin hole or projection is formed at the lower end. Then, by connecting the cross bracings to the cross bracing pins, the building opposite to each other is connected to each other sequentially in a self-standing manner, and a required floor fabric or skirting board is required between adjacent constructions. A temporary scaffold is constructed by erection.

生上の対策を講じる必要があった。By the way, since the attachment of the cross-brace pins to the pillars constituting the above-mentioned building, or the processing of the connecting pin holes and projections, has been generally performed by hand conventionally,
The installation work and the processing work take time and are extremely inefficient. In addition, the positioning of the mounting position and the like are very troublesome, and the quality tends to vary. And in particular, the strut 101
At the time of installation, as shown in FIG. 7, since it was supposed to be performed manually mainly by carbon dioxide welding means, it takes a very long time and the work efficiency is extremely poor.
Not only spatter adheres to the outer peripheral surface of the welded part and causes unevenness of the bead width, which greatly impairs the appearance, but also tends to cause variations in welding strength due to differences in the skill level of the workers and even by the same worker. Met. In addition, when welding to the hot dip galvanized pipe material, the galvanized layer is peeled off and discolored, and a correction treatment is required, which not only significantly impairs the appearance but also lowers the rust prevention power, and In addition, toxic gas is generated due to the combustion of the galvanized layer and the working environment is deteriorated, so that it is necessary to take additional safety and health measures.

成する。First, the pipe member A is arranged and supplied on the guide rail 14 while the dispensing member 15 is operated. At this time, the pipe material A located at the front row of the guide rail 14 is locked by the rise of the pipe stopper 18, and the second-place pipe material A is pressed and fixed by the lowering of the fixing member 16. Thereafter, the operation of the fluid pressure cylinder 19 causes the pipe stopper 18 to operate.
Is lowered, the pipe material A in the front row is released and sent out. When the delivery of the pipe material A is completed, the pipe stopper 18 rises again and the hydraulic cylinder 17
Operation raises the fixing member 16, and the second-place pipe material A
Is released and locked by the pipe stopper 18, and when the locking is completed, the fixing member 16 is lowered again to press and fix the pipe member A located at the second position. Thereafter, similarly, the pipe material A is sequentially and intermittently sent out (see FIG. 4). The pipe material A, which is sequentially and intermittently sent out, causes the bogie 22 to reciprocate along the transport rail 21 by the fluid pressure cylinder 23, so that the first chuck 24 uses the first positioning device 29 to cause the second positioning device 36 to perform. The second positioning device 36 with the second chuck 25 to the projection welding machines 38 and 39,
Projection welders 38 and 39 with the third chuck 26
Then, they are continuously and intermittently transferred to discharge sections (not shown), and required processing is performed (see FIG. 6). That is, the pipe material A intermittently sent from the sending device 13 is held by the first chuck 24 via the transfer member 27. Then, the first positioning device 29 advances and the pipe material A is moved by the chuck 34.
The chuck 34 is rotated and positioned to properly position the processing position by detecting the beat of the pipe material A by detecting one end of the pipe material A. At this time, the first chuck 24 is opened simultaneously with the gripping by the first positioning device 29 to release the pipe material A and stop at the same position. When the positioning of the pipe material A is completed, the first positioning device 29 moves forward along the swing rail 31, and holds the free end of the pipe material A on the press 28 while horizontally holding the pipe material A on the pedestal 44. Perform projection or drilling. When the processing is completed, the first positioning device 29 retreats and returns to the original state, and the chuck 34
Is opened to release the pipe material A. Then, the first
After gripping the pipe material A, the chuck 24 transfers the pipe material A to the second positioning device 36. And, similarly,
After detecting the bead of the pipe material A by the second positioning device 36 and positioning the processing position, the pipe material A is moved forward while being gripped by the chuck 34, and the other end of the pipe material A is pressed.
Drill with 35. At this time, the first chuck
Reference numeral 24 releases the pipe material A and returns to the original state at the same time, and the second chuck 25 is positioned at the same position. When the boring process is completed, the second positioning device 36 retreats and returns to the original state, and the chuck 34 is opened to release the pipe material A. Then, after the second chuck 25 grips the pipe material A, the second chuck 25 transfers the pipe material A to the first and second projection welding machines 38 and 39, and places both ends of the pipe material A on the lower electrode 41. At this time, the second chuck 25 places the pipe material A on the lower electrode 41 and, at the same time, returns to the position of the second positioning device 36 in an open state, and the third chuck 26 is positioned at the same position. Then, after the crossed brace pins 3 sent out from the parts feeder 42 are supplied to the respective upper electrodes 40 by the chuck hand 43, current is applied and pressurized to perform projection welding, thereby completing the manufacture of the pillar 2 (fifth embodiment). See figure). When the production of the pillar 2 is completed, the third
The chuck 26 grasps the pillar 2 and transfers it to the discharge unit,
The pedestal 2 is discharged by the opening operation. As shown in FIG. 1, the generated pillar 2 is assembled by a known means to form a building 1.
