夫はされていた。2. Description of the Related Art As shown in FIG. 7, a tread plate 12 which serves as a lid for a concrete gutter generally provided at the end of a road is provided as follows.
It is formed in a substantially rectangular plate shape by concrete, and a rectangular drainage hole 15 is formed to form a drainage hole along a long side thereof. This type has a grating 41 due to its large hole. FIG. 8 shows a lid with a U-shaped groove and a small drainage hole. FIG. 9 shows a notch B for handling on the short side of the lid A, and U on the long side.
It is fitted in the groove of the U-shaped groove C and is supported at the edge of the U-shaped groove C. In such a tread plate 12, since the drain hole 15 is left as a hole, the tread plate 12 is inserted into the hole.
The foot of a pedestrian walking on a bicycle or the wheel of a bicycle may fall and fall or be injured. Further, in order to solve such a problem, it has been devised to reduce the size of the drain hole 15 by inserting a grating net as a concrete bone.

た。However, in the case where the drainage hole 15 is made smaller with a grating net, it is good at the beginning, but as time passes, the drainage hole 15 is corroded by acid or salt or chlorine gas due to chlorine flowing through the side gutter, There was a problem that the net fell off due to the interposition of the elements. On the other hand, if the hole 15 is small, water easily accumulates on the tread plate 12 and slips off when the grating net is wet.

ができて一石二鳥の効果がある。As described above, according to the present invention, the hole cover 20 of the tread plate can be attached to the existing tread plate 12 without any modification and with or without grating. Since the fastening operation can be performed, the mounting operation of the tread plate 12 is easy, and the tread plate 12 to which the hole cover 20 of the tread plate is mounted improves the safety of a person or a bicycle walking on the tread plate 12. Further, the hole cover 20 of the tread plate can be easily removed without breaking the tread plate 12 itself or the tread plate 12, and does not hinder repair or replacement of the tread plate 12. The hole cover 20 of the tread is generally made of a synthetic resin, and is excellent in water resistance and weather resistance as well as mass productivity. The hole cover 20 of the tread plate is chamfered at the periphery and becomes low, and has excellent drainage due to the anti-slip projections 22 and the water holes 21, so that it may interfere with walking or become uneven to the bicycle. Not only, hole 15
This eliminates a decrease in air permeability inside and outside the side groove due to closing.
If the hole cover 20 of the tread plate is colored in a fluorescent color, the driver of a car or a bicycle at night can recognize the position of the gutter, which has an effect of two birds per stone.
