This is done by passing the joint reinforcing bar through the through hole formed in the. Even in this case, similarly to the first invention, even if these joining reinforcing bars are to be welded, it is not necessary to perform difficult welding along the line where the surface steel sheet comes into contact, unlike the conventional case. And, in the joint rebar connecting the upper, lower, left and right units, the surrounding concrete is constrained by the surface steel plate and the partition wall or shear plate, so that the adhesion strength with the concrete becomes large, and if the joint surface of each unit joins them Even if the rebar yields, it does not slip out because it is restrained and reinforced from the surroundings, and the bond length can be made as short as possible.

左右されない。As described above, according to the method for constructing a steel plate concrete wall of this embodiment, the joining of the units 1 is
Since it is performed by passing the joining rebar 19 through the through hole of the partition wall 5 in the left-right direction and through the through hole of the rebar receiving plate 17 in the up-down direction, it is difficult to perform along the line where the surface steel plate 3 contacts as in the conventional case. No welding 11 (FIG. 4) is required. For this reason, joining can be performed without depending on the skill of a skilled worker who performs welding. Further, it is not necessary to perform time-consuming welding along a long line with which the surface steel sheet 3 is in contact, and therefore, the welding work can be performed regardless of the weather. Therefore, the construction period for constructing the steel plate concrete wall can be shortened, and the cost of the steel plate concrete wall can be reduced. However,
Joined reinforcing bars passed through the through-holes may be welded if necessary, or surface steel sheets may be temporarily fixed by spot welding if necessary, but such welding is small in amount, especially It does not require skill and is not so sensitive to the weather.

る。In addition, since each concrete reinforcing bar 19 for connecting the upper, lower, left and right units 1 to each other is bounded by the surface steel plate 3 and the partition walls 5 or the shear plates 13a and 13b, the strength of adhesion to the concrete is large. Therefore, it is possible to prevent the adhesion failure between the concrete and the joining rebar 19 to be broken, and thereby to sufficiently transmit the stress. Even if the joining rebars 19 of each unit 1 yield at the joining surface position, they are restrained and reinforced from the surroundings, so that they do not come out and the attachment length can be shortened as much as possible. .

良い。The provision of the horizontal shear plate 13a may impede the fluidity of concrete to the left and right joints of each unit 1, but this is because the notch 14 is formed in each horizontal shear plate 13a. This can be solved by providing it or by using concrete having excellent fluidity, and the lateral shear plates 13a of the left and right units 1 may be arranged so as to be offset from each other.

You don't have to. However, in this case, the left and right units 1 are joined to each other by joining the reinforcing bars 1 through the partition walls 5.
After joining at 9, the concrete is placed between both surface steel plates 3 up to the vicinity of the upper end portion thereof, and before the concrete is solidified, a reinforcing bar is constructed as a joining rebar vertically on the concrete placing surface.

Since the upper, lower, left, and right of each unit can be joined by the joining rebar, it is not necessary to perform the difficult welding work of welding the surface steel sheets of adjacent units along the contact line as in the past, and the skill of performing welding It is possible to construct a steel plate concrete wall with stable quality regardless of the workmanship and weather. Also, the unit construction work can be shortened regardless of the weather, and the construction period can be shortened.
The cost of steel plate concrete walls can be reduced.

Further, even if the joining rebars of the units are yielded at the joining surface position, they are restrained and reinforced from the surroundings, so that they do not come out, and the attachment length can be shortened as much as possible.
