In addition, there is a problem that the processing load is increased due to the cold working, so that the processing cost is also increased.

The deformed wire is not often used. The reason for this is that a thin wire is generally manufactured by wire drawing in which the wire is thinned through a hole of a thin die in a cold state, and it is difficult to manufacture a deformed wire by wire drawing.

In view of the above, it has been studied to produce a deformed wire having a small diameter (nominal diameter of less than 6.35 mm) directly by hot working without the cold working.

Compared to cold working, the depth of the dent can be increased, the height of the rib can be increased, and the specific surface area per volume can be increased. In particular, as shown in FIG. It has been found that the smaller the diameter of the wire, the greater the specific surface area, and therefore, the adhesive strength to concrete increases as compared with a round iron wire.

圧延が必要となる。ところが、細径線材は剛性が弱いた
め高速圧延では座屈変形し、通材トラブルが発生する。DESCRIPTION OF THE PREFERRED EMBODIMENTS High-speed rolling is required to produce a deformed wire having a small diameter (nominal diameter of less than 6.35 mm) by hot rolling. However, the small-diameter wire rod has a low rigidity, so that it buckles and deforms in high-speed rolling, which causes a trouble in threading.

般的であった。[0018] For this reason, it has not been hitherto manufactured a fine-diameter wire rod by hot rolling. That is, in the past, thin wires were generally produced by cold drawing after hot rolling and then thinning through holes of a thin die.

により、公称直径６．３５ｍｍ未満の細径の異形線条材
の熱間圧延による製造が可能となることを確認した。By using a water cooling zone with a small bore diameter, a tension control, a laying head for winding at a high speed, and the like, the present inventor can produce a thin, irregularly shaped wire having a nominal diameter of less than 6.35 mm by hot rolling. Has been confirmed to be possible.

ができた。In the hot rolling, high-temperature steel is rolled and formed between a pair of finishing rolls having a caliber having a convex shape opposite to a concave shape of a product having an elliptical cross-sectional shape. As a result, it was possible to produce a deformed wire.

できることを見出した。Further, the deformed thin wire having a small diameter manufactured by hot rolling can have a greater depth of the recess and a higher rib height than a cold-worked material such as deformed work.
It has been found that the specific surface area, which is the surface area per volume, can be increased.

表面積を比較して示してある。FIG. 1 is a diagram showing the relationship between the wire diameter and the specific surface area. In FIG. 1, round iron wire, nominal diameter 6.35 mm
Hot-rolled deformed wire rod with a diameter of ~ 16 mm and a nominal diameter of 6.35
The specific surface area of the hot-rolled deformed wire rod of less than 1 mm (the present invention) is compared and shown.

となることが分かる。As is apparent from FIG. 1, the hot-rolled deformed wire has a large specific surface area per volume compared to a round iron wire because of its unevenness. And, as for the hot-rolled deformed wire, the smaller the wire diameter, the larger the specific surface area. For example, it can be seen that a wire having a wire diameter of 4 to 6 mm has a specific surface area approximately three times larger than a wire having a wire diameter of 10 to 13 mm.

このため、コンクリート製品の強度を高めるための一つ
の重要な要件として、異形線条材とコンクリートとの付
着強度の高いことが要求される。The deformed wire as a reinforcing bar of a concrete product (concrete building structure) is bent into a shape similar to that of the concrete product, and is subjected to welding and forming. Then, the concrete product is obtained by being set in a mold and pouring concrete into the mold.
For this reason, as one important requirement for increasing the strength of the concrete product, a high bond strength between the deformed wire and the concrete is required.

い。As shown in FIG. 1, the thin strip of the present invention produced by hot rolling with a nominal diameter of less than 6.35 mm, especially 4 to 6 mm, has a smaller volume per volume than a round iron wire. The specific surface area is large, and the adhesion strength with concrete is greatly improved. Therefore, in the present invention,
The nominal diameter of the deformed filament was limited to less than 6.35 mm.
The lower limit of the nominal diameter is not particularly limited,
It is preferably 3 mm from the viewpoint of manufacturing conditions and practicality.
【００２６】次に、異形線条材をコンクリート製品に類

要なことは、曲げ加工性が良いこと、及び溶接性が良い

れ、しかもそのバラツキは少ない。For this purpose, it is necessary to make the outer shape of the deformed wire substantially circular, and to increase the outer surface area with respect to the total surface area. An indented wire having a substantially circular outer surface and a concave has less bending angle variation and has better bending workability. To increase the welding strength, it is better that the contact area of the welded portion is large. The larger the outer surface area relative to the total surface area, the larger the welding area and the higher the welding strength. Since the outer surface of the indent wire is substantially circular and has a recess, it is welded on the outer surface having a large area, so that a large welding area can be obtained and the variation is small.

(A vertical rib) 5. The angle 6 between the horizontal rib and the axis is formed at 60 degrees. This angle can be arbitrarily changed in the range of 30 to 90 degrees according to the tension direction of the concrete product.

A pull-out test according to No. 21 was performed.

The cold working (drawing and deforming) steps as in the conventional case can be omitted, and the production cost can be reduced. In addition, the improvement of the adhesive strength with the concrete improves the breaking strength of the concrete product and enables the use of thin reinforcing bars, so that the amount of reinforcing bars can be reduced and the weight of the product can be reduced. Further, since the specific surface area is large, the area of the welded portion is increased, and the effect of improving the welding strength is achieved.
