[0008]

According to the above construction, the present invention, when installed in a drain or the like provided in a corner of a floor of a balcony, has an upper surface on both side walls of the drain of the balcony, that is, a floor located near the groove of the drain. The back surfaces of a pair of aluminum grating side bars are brought into contact with each other to cover the groove. At this time, the side wall of the drainage groove is brought into contact with a pair of aluminum grating projecting plates so as to regulate the deviation of the aluminum grating from a predetermined position such as a lateral deviation. The main bar made of aluminum grating has a cross section that extends upward in the longitudinal direction.
Since the surface shape has a substantially T-shaped tread, there is no particular problem even if a resident or the like steps into it, and an ornament such as a flower pot into which houseplants or the like are planted positively may be placed.

When rainwater or the like falls or the inside of the balcony gets wet due to water sprinkling, the rainwater or the like flows down a water flow path formed in aluminum grating in the longitudinal direction, and drains through a water hole formed in the water flow path. It flows down into the groove. Rainwater or the like that has flowed down into the drainage ditch is discharged into a drainage pipe through a drainage port provided in the drainage ditch and is subjected to sewage treatment.

In addition, the receiving holes formed on both end surfaces in the longitudinal direction of the aluminum grating are provided for enhancing the decorativeness of the entire aluminum grating and for replenishing the gap between the end of the aluminum grating and the wall of the balcony. The projections of the mounting member and the connecting member are inserted and fitted.
