題になることはない。2. Description of the Related Art Grooved reinforced concrete sheet piles are widely used as river or marine seawalls, and in this case, they are connected to and supported by tie rods and tie rods buried on the ground side behind them. Often used.
In this case, when the tie rod is attached to the sheet pile at a high position and is the head of the sheet pile, the tie rod 2 is made to penetrate the grooved reinforced concrete sheet pile 1 as shown in FIG. In general, the nut 9 is screwed into the end portion of the shape rope 5 through the gap of the shape rope 5 and fixed to the front of the sheet pile with the groove rope 5 interposed therebetween. Since this mounting portion is wrapped in the shade concrete 7 for a while, there is no particular problem in terms of aesthetics and rust prevention of the channel rope.

付けるのが一般的である。However, it is sometimes necessary to mount the tie rod at a low position not to be wrapped in the concrete 7 of the sheet pile. In this case, the tie rod is required to be aesthetically pleasing and to prevent the tubing from being rusted. 5 and the tie rod 2 are required to be fixed to the rear side of the channel-shaped reinforced concrete sheet pile 1. In this case, if the channel 5 is directly attached to the back of the channel reinforced concrete sheet pile 1, the tie rod 2 is attached to the channel 5.
Since it is not possible to secure a space for fixing (bolt-fastening), as shown in FIG. 6, first, a box fitting 12 for securing a space is attached to the back of the channel-shaped reinforced concrete sheet pile 1, and this box is provided. Generally, the channel 5 is attached to the metal fitting 12.
