DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an SC wall (steel-concrete wall) as an earthquake-resistant wall in the fields of civil engineering and construction.

[0002]

2. Description of the Related Art As a general seismic wall, there is an RC wall (reinforced concrete wall) having an increased amount of reinforcing bars or a built-in brace. There is also a trend to use (steel / concrete walls).

The SC wall 1 will be described with reference to FIGS.
The concrete 6 is filled between the steel plates 4 and 5 arranged side by side at intervals with being disposed in the frame of the steel and the beam 3.

[0004] The steel plates 4 and 5 are flat plates. As shown in Figs. 4 and 5 are often connected by a steel bar 7 or the like.

[0005]

The steel bar 7 is provided with a hole in one of the steel plates 4, inserted between the steel plates 4 and 5 through the hole, and fixed by welding. The structure to be placed complicates the construction and raises the cost of the entire SC wall.

An object of the present invention is to eliminate the disadvantages of the prior art, eliminate the need for connecting steel plates to prevent entanglement, provide a simple and inexpensive construction, and provide a highly rigid SC wall. .

[0007]

According to the present invention, in order to achieve the above-mentioned object, in an SC wall in which concrete is filled between parallel steel plates, a continuous steel plate having irregularities is used as the steel plate. When the concave part of one steel plate and the convex part of the other steel sheet, the convex part of one steel sheet and the concave part of the other steel sheet face each other and the concrete is filled, the thin part and the thick part of the wall are alternately continuous. It is intended to be formed in a general manner.

[0008]

According to the present invention, since a steel plate having a continuous shape with irregularities is basically used, the out-of-plane rigidity is larger than that of a flat steel plate.
It is possible to eliminate the need for anti-trapping.

Moreover, the steel plates are arranged side by side so that the concave portion of one steel plate and the convex portion of the other steel plate and the convex portion of one steel plate and the concave portion of the other steel plate face each other.
The pillars are arranged at intervals with the same effect as the C pillars. And since the columns are arranged at equal intervals and the space between them is connected by a thin part, it is as if a panel was fitted between the parallel columns, and by providing a pillar-like existence, Regardless, it has high bending performance (toughness) and rich deformation performance.

Although the thin part is weaker in strength than the thick part, the thin part is basically made of a combination of steel plate and concrete and therefore has a certain strength. There is no problem because the thin part is supplemented with the strength by the adjacent thick part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional plan view showing a first embodiment of the SC wall according to the present invention.

The SC wall 1 of the present invention is also formed by filling concrete 6 between steel plates 4 and 5 arranged in parallel, and the steel plates 4 and 5 are of a square wave type having a continuous shape of a concave portion 8 and a convex portion 9. The deck plate type was used.

In this embodiment, as shown in FIG. 1, the concave portion 8 of one steel plate 4 and the convex portion 9 of the other steel plate 5 are combined with the convex portion 9 of one steel plate 4 and the concave portion 8 of the other steel plate 5. When the concrete 6 is filled in such a manner as to face each other, the thin portion and the thick portion α of the wall are formed alternately and continuously.

As described above, the steel plates 4 and 5 having the continuous shape of the concave portion 8 and the convex portion 9 have a large out-of-plane rigidity, and do not get stuck when the concrete 6 is poured.

In the case of FIG. 1, the thick portion α has the same function as a column, and the thick portion α is arranged at intervals, which is equivalent to the column being arranged at equal intervals.

FIG. 2 shows a second embodiment of the present invention.
The steel plates 4 and 5 having the continuous shape of the concave portions 8 and the convex portions 9 were corrugated steel plates.

In this embodiment, the concave portion 8 of one steel plate 4 and the convex portion 9 of the other steel plate 5 are opposed to each other, and the convex portion 9 of one steel plate 4 and the concave portion 8 of the other steel plate 5 face each other. And the thick portion α are alternately and continuously formed.

As other examples, the steel plates 4 and 5 may have various shapes as long as they have a cross section of a repetitive pattern of the concave portions 8 and the convex portions 9.

[0019]

As described above, the SC wall according to the present invention does not require the connection between the steel plates to prevent entanglement, and can be constructed with a simple structure and at low cost. In addition, since the thick portions are arranged at intervals, it becomes equivalent to the columns arranged at equal intervals, and a wall having a high deformability can be obtained by the bending performance.
