防止することが知られている。[0003] Therefore, in order to prevent the displacement of the laid iron plates and the sinking of the laid iron plates, various techniques for connecting the laid iron plates with the end faces of a plurality of the laid iron plates laid on soft ground etc. are adopted. Has been done. As such technology,
For example, as shown in FIG.
The reinforcing bar 200 is sandwiched between the edges of the
0 is welded to the upper surfaces of the laying iron plates 105, 105 so that the laying iron plates 105, 10 adjacent to each other via the reinforcing bar 200
It is known that the five members are connected to each other to prevent the position of the laid iron plate 105 from being displaced and the subsidence.
