Abstract

PROBLEM TO BE SOLVED: To obtain a transformed shape steel, which is various in size and shape and which is hardly affected by a weight increase or cost increase, by using the shape steel, only the standardized one of which has been available heretofore. SOLUTION: The web parts of two pieces of shape steel are cut into two, upper and lower parts and in any similar shapes. The upper cut part 11 of one piece and the lower cut part 12 of the other piece are made to abut each other in the web part 9 cut before. The abutted part 10 is welded in order to regenerate two piecdes of shape steel with the web pierced with holes.

[0004] For the above-mentioned rolling work, a huge amount of equipment investment such as the use of a control computer in addition to the rolling equipment and the execution of controlled cooling is required. Special steel bars cannot be easily met with demand. As described above, it has been difficult to respond to the social demands for diversification of cross-sectional sizes and high-mix low-volume production of section steels.

[Problems to be Solved by the Invention] Since the production of the shape steel itself is carried out by using a large-scale rolling equipment and accompanying technology such as computer control and cooling control, deformed shape steel or special shape steel is used. It is easy to imagine that if the shaped steel bars were forcibly manufactured, the manufacturing costs would rise extremely and would be unprofitable. Therefore, despite the fact that it was strongly desired to obtain a desired shape steel without causing any cost-up factor, and to be able to freely change its size and shape, there was no way to supply it. The present invention
The purpose is to obtain a mold steel having a changed shape and dimensions without causing cost-up.

[Means for Solving the Problems] The two mold steels are divided into upper and lower portions at the web portion into an arbitrary same shape, and another cut upper portion and a cut lower portion are joined to each other at the cut portion web portion, and welding is performed. This problem was solved by going and regenerating two mold steels each having a gap. Also, not the web part, but a notch of the same shape in the flange part,
When the flange portions are butted and welded to each other, a prism having an air gap is obtained. As a result, arbitrary shaped steel having different rated dimensions can be obtained.

[Operation] The dimensions and shape of a conventional mold steel are different from those of a conventional mold steel by dividing two mold steels into upper and lower two parts at the web part and arbitrarily arranging the same cross section. And because it can be regenerated as deformed steel with voids, new applications can be expected and the weight increase is small,
A new deformed steel with less cost-up factor can be obtained.

As shown in FIG. 1 (A), two commercially available H-section steels 1 are used, and as shown in FIG. Web part 9 of H-section steel 1 using a laser cutting machine capable of cutting
And cut into two. Although the cutting shape is not particularly specified, when re-welding as described later, the shape is desirably a shape excellent in aesthetic sense in terms of design, and the molten surface is formed so as to retain the strength as an H-shaped steel. Therefore, it is desired that the shape of the reweld surface is sufficiently large so that the rewelded surface can be sufficiently obtained, and that the number of straight sections is generally large. Therefore, an arc-shaped welded surface or a shape with a small reweld surface even if it has decorativeness is not very preferable.

When the butt welding 10 is performed so that the divided cut upper part 31 and another cut upper part 31 whose direction is changed by 180 degrees are as shown in FIGS. 2B and 2C, the width of the web part 9 is narrow at the tip and thin at the base. However, H-shaped steels 4 and 4 ′ having different diameters and a clear gap 13 are obtained.

[Effects of the Invention] Conventionally, only a standard shaped steel could be obtained. However, in the deformed steel according to the present invention, any shape steel different from the standard steel can be easily obtained by devising a web cutting line. At the same time, since the air gap is provided in the web portion, the weight per unit volume of the mold steel is reduced, and as a result, the weight of the entire steel structure is also reduced. It will be easier. Since the manufacturing method is only fusion of the section steel and subsequent butt welding, the cost increase factor is small, the price up factor for the steel material is small, and it does not become a hindrance factor for the price for the steel structure. In addition, even if the steel mold is configured as a steel structure that is exposed to the outside, there are many advantages such as adding a design element to the shape of the voids so that there is a decorative element so that it will not be particularly unsightly even if left unattended. is there.
