「産業上の利用分野」
本発明は、ＳＲＣ造、ＲＣ造等の建築物に用いる縞付り
形鋼に関するものである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a striped steel section used for buildings such as SRC construction and RC construction.
「従来の技術と発明が解決しようとする問題点」従来、

いられる。"Problems to be solved by conventional technology and invention" Conventionally,
Prefabricated steel frames made of L-beams are often used in SRC buildings.
しかし、この場合、Ｌ形鋼とコンクリートとの付着性が
悪く、十分な耐力を発揮できない憾みがあった。However, in this case, the adhesion between the L-shaped steel and the concrete was poor, and there was a problem that sufficient yield strength could not be exhibited.
本発明は、斯る従来の問題点を除去しようとするもので
ある。The present invention seeks to eliminate such conventional problems.
［問題点を解決するための手段及び作用ｊ本発明は、Ｌ
形鋼の表面に縞状の凹凸を形成して成る。[Means and effects for solving the problems j The present invention is based on L
It is made by forming striped irregularities on the surface of a shaped steel.

物における柱および梁の鉄骨として、あるいは、ＲＣ造
の建物における柱の芯鉄骨として用いる。A plurality of striped steel sections are arranged in parallel and connected and integrated using a large number of connecting pieces such as hand plates to form assembled steel frames such as ladder shapes, truss shapes, lattice shapes, etc., and are used in SRC buildings. It is used as a steel frame for columns and beams, or as a core steel frame for columns in RC buildings.

FIG. 2 shows another example, which is made by combining two thick plates with striped irregularities 2 and building them up into an angle iron shape. Any unevenness may be formed during the rolling process of the shaped steel.
なお、スタッドを併設してもよい。Note that a stud may also be provided.

鉄骨Ａに形成する。When using the above-mentioned striped (t L-shaped steel 1) as an assembled steel frame for SRC columns, as shown in Figure 3, four striped shaped steel 1
11 are placed parallel to each other at the four corners of a square, and are connected and integrated into a ladder shape as shown in Fig. 4, a lattice shape as shown in Fig. 5, etc. using a large number of connecting pieces 3 such as band plates. Form into A.
