Description of the Related Art Various types of conventional steel structures for retaining walls are known, but they are commonly H-shaped, and a portion corresponding to a web is a plate-shaped material. At least a portion corresponding to one of the flanges has a straight steel sheet pile, and has a structure in which a wall is formed by connecting claws of the straight steel sheet pile.
For example, what is shown in FIG. 2 is an H-shaped steel sheet pile in which a straight steel sheet pile is welded to a T-shaped steel sheet obtained by welding two thick steel plates 4, 4 described in Japanese Utility Model Laid-Open No. 7-31934.

物を提供することを目的とする。However, the H-shaped sheet pile is restrained to keep a member equivalent to a flange and a member equivalent to a web in a fixed posture in order to prevent welding distortion and secure posture stability during welding. There is a problem that means is required. Therefore, an object of the present invention is to provide a steel structure for retaining walls that can be easily formed by welding.

鋼矢板を使用するのが特徴である。BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a steel structure for retaining walls according to the present invention is obtained by welding a straight steel sheet pile 1 to a web (1 ') side of a U-shaped steel sheet pile 5 by joining a joint portion ( 1 '') is formed by welding a thick steel plate 4 to the side. Whereas the conventional one uses a flat steel plate for the web equivalent part, the present invention is characterized in that a U-shaped steel sheet pile is used for the web equivalent part.

溶接作業性及び溶接能率が従来に比し格段に向上する。Since the U-shaped steel sheet pile has a shape that can be stably stood on any side in the height direction, the U-shaped steel sheet pile is first formed into a straight shape with the web side at the bottom. The left and right corners may be welded by arranging them on a steel sheet pile and then arranging them on a thick steel plate with the joint side as the bottom. Since the stationary stability of the member to be welded is high, welding distortion does not occur without providing a separate restraining means, and simultaneous left and right corners can be welded simultaneously.
Welding workability and welding efficiency are significantly improved as compared with the past.

きる。Further, for various strength and rigidity requirements,
The U-shaped steel sheet pile has a wide selection of thicknesses, so it is easy to select the one that meets the requirements, and if it is insufficient, the thickness and width of the steel sheet can be freely adjusted to compensate for the shortage. Because it is easy, the request can be flexibly dealt with even if it is wide. In addition, according to the present invention, since the allowance for freely adjusting the strength and rigidity is large as described above, the configuration shown in FIG. It is possible to provide the strength and rigidity corresponding to FIG. 3 (b). Therefore, with the same continuous wall length, the welding line is reduced to about 1/3 of the conventional (every three sets of conventional continuous wall lengths). 12
In the present invention, it is possible to save four to the same length).
