不経済となる問題があつた。 Conventional steel materials of this type include, for example, a grooved steel 5 with a square cross section and connecting joints 4 provided at both ends as shown in FIG. 1, or an equilateral H-shaped steel 6 as shown in FIG. It is known that a connecting joint part 4 is provided at both ends of each flange 7. However, the one shown in Fig. 1 has lower rigidity per unit weight ratio than the equilateral H-beam 6 shown in Fig. 2, and is uneconomical as it must be thick-walled in order to obtain the necessary stiffness. It is something. Also, in the case of the one in Figure 2, the flange 7 is equilateral, so if the retaining wall is non-linear in cross section or has corners, the third
As shown in the figure, the flanges 7 of adjacent equilateral H-beams 6 get in the way and cannot be connected.
Further, in the case of this equilateral H-shaped steel 6, there was a problem in that the connecting joint portions 4 at both ends of one flange 7 were excessive, making it uneconomical.

１同士を連結できるものである。 The present invention provides a scalene H-beam steel 3 in which one width of one flange is longer than two widths of the other flange, and a flange 2 of which is shorter than the thickness of the longer flange 1.
This relates to a steel material for retaining walls, which is characterized by having a thicker flange 1 and having connecting joints 4 provided at both ends of the longer flange 1. This will be explained in detail below using examples. FIG. 4 shows an example of a steel material 9 for a retaining wall according to the present invention, in which one side of a conventional narrow H-shaped steel flange is extended to both sides to form a flange 1 having an extension 8. Therefore, the flange 1 having this extension 8 has a longer width than the other flange 2. The thickness of the shorter flange 2 is thicker than the thickness of the longer flange 1, and the ends of the extensions 8 at both ends of the longer flange 1 have a C-shaped cross section, a hook shape, etc. A connecting joint portion 4 is provided. Here, a specific example of the steel material 9 for retaining walls of the present invention is shown in FIG. 4: A=400mm, B=600mm, B'=200mm,
t 1 = 4.5 mm, t 2 = 6 mm, t 3 = 18 mm, but of course they are not limited to the above values, but the relationship t 3 > t 2 should be satisfied, and the longer one The thickness of the shorter flange 2 is made thicker than the thickness of the flange 1. However, soil cement pillars and soil cement asphalt pillars 11 are placed on the ground 10.
When this soil cement column or soil cement asphalt column 11 is uncured, the steel material 9 for the retaining wall is inserted, and the steel material 9 for the next retaining wall is connected to the connecting joint part 4. are inserted while engaging as guides, and the adjacent steel materials 9 for retaining walls are connected to each other at the connecting joint portion 4, and in the same manner, the steel materials 9 for retaining walls are successively connected to each other at the connecting joint portion 4. In this way, a retaining wall made of soil cement, soil cement asphalt, etc. is formed using the steel material 9 for retaining walls as a core material. Here, the steel material 9 for the retaining wall serves as a stress member of the retaining wall, and also serves as a water-stopping member when connected through the connecting joint portion 4. In the above embodiment, an example of a mountain retaining wall made of soil cement, soil cement asphalt, etc. in which the steel material 9 for a mountain retaining wall is used as a core material was shown. It goes without saying that the retaining wall may be formed by erecting the retaining wall using the impact method, vibration method, or press-fitting method and connecting the connecting joint portions 4 of adjacent steel materials 9 for retaining walls. By the way, in the case of the steel material 9 for retaining walls of the present invention, one flange 1 is longer than the other flange 2, so even if the retaining wall is non-linear or has a corner part, it will not work as shown in FIG. The shorter flanges 2, 2 of the steel material 9 for the retaining wall adjacent to each other do not interfere with each other, and the longer flanges 1,
1 can be connected to each other.

全体の強度のバランスがとれる。 In the present invention, as described above, in the scalene H-shaped steel whose flange width is longer than the other flange width, connecting joints are provided at both ends of the longer flange, so that the shape of the H-shaped steel is improved. It is economical because it has no excess parts while maintaining the rigidity of the unit weight ratio, and since it is an H-shaped steel, it is also a scalene H-shaped steel, so when connecting joints, it is possible to avoid straight lines. Even if the flange does not have a connecting joint part, it can be connected without getting in the way even if it is a shape or a corner part. Although the width of one flange is longer than the width of the other flange so that the flange without the connecting joint part does not get in the way even at the corner part, the longer one Since the thickness of the shorter flange is made thicker than the thickness of the flange, the strength of the shorter flange does not decrease, and the strength of the entire H-shaped steel can be balanced.
