とするものである。Conventionally, in order to manufacture a vessel or storage tank using a stainless steel plate, preventing distortion that occurs when attaching a circular or square large diameter nozzle to the steel plate by welding has been an important processing issue. The present invention aims to solve this conventional problem, and a base steel plate in which an opening for nozzle attachment is previously provided is fixed by a clamp on a surface plate having a concentric opening slightly larger than the opening, and the opening in the steel plate is Provided is a method for attaching a nozzle to a steel plate, characterized in that a predetermined nozzle is welded to the opening of the steel plate after the periphery and the opening end of the surface plate are fixed and integrated via a plurality of steel pieces over the entire circumference of the opening. This is what I am trying to do.

止するためのものである。To explain the present invention in detail, a stainless base steel plate 3 having a rectangular opening 2 in which a nozzle 1 is attached is placed on a pedestal with a concentric opening 4 having a similar shape slightly larger than the opening. It is placed on a surface plate 5 placed on the surface plate 5 and fixed with clamps 6 placed around the outer periphery. Reference numeral 7 indicates a pull pin, which is driven between the clamp 6 and the surface plate. Next, the surface plate 5 and the steel plate 3 are turned over as one unit, placed on a frame, and the periphery of the opening 20 of the plate 3 and the end of the opening 4 of the surface plate 5 are covered with a plurality of steel pieces 8 over the entire circumference of the opening. They are fixed and integrated by intermittent bath welding. This piece 8 is formed by appropriately cutting a flat bar or other shaped steel. After that, a predetermined nozzle 1 is attached to the opening 2 of the steel plate 3 by welding. In this case, it may be attached with the surface plate 5 on top and the steel plate 3 on the bottom, or it may be inverted and the surface plate 5 It is also possible to temporarily attach the nozzle with the steel plate 3 facing down and the steel plate 3 facing up, then turn it over again and weld. When the installation of the nozzle ■ to the steel plate 3 is completed, remove the steel piece 8 from the steel plate 3 by removing the intermittent welds with a grinder, and if necessary, remove the steel plate 3 with a grinder.
Finish off the remaining steel piece installation marks. Note that 9 in the figure is a sheet interposed between the surface plate 5 and the steel plate 3 to prevent rust and other stains on the surface plate 5 from adhering to the steel plate 3.

とができる。To explain the effects of the present invention, the periphery of the nozzle mounting opening previously provided in the base steel plate and the end of the opening, which is concentric with the opening and is slightly larger, and which is provided in the surface plate, are By welding a designated nozzle to the opening of the steel plate while being fixed and integrated through multiple steel pieces around the circumference, it is possible to completely prevent the distortion that conventionally occurs in the steel plate when installing the nozzle. Since this is possible, it is possible to provide an extremely superior method of attaching a nozzle to a steel plate that can improve the quality of the vessel or storage tank and improve efficiency by eliminating the need for strain removal work.
