Description

The combined structure of the grating cover {COMBINED STRUCTURE OF GRATING COVER}

An embodiment of the present invention relates to a coupling structure of a grating cover capable of installing and fixing the grating cover in a simple and easy manner on the upper portion of the grating in order to prevent the inflow of foreign substances into the drain.

In general, when rainwater is generated intensively due to rainfall, it may cause inundation in a specific area. Therefore, a drainage channel provided with a separate drain hole for collecting rainwater is formed on the road or sidewalk side.

For the safety of pedestrians or vehicles, the drain hole consists of an end bar seated at both ends of the drain hole, a plurality of bearing bars connecting both end bars, and a plurality of cross bars intersecting the bearing bars for reinforcement of the bearing bars. A grating forming a drain hole is installed.

However, since the conventional grating has a large drainage hole formed by the bearing bar and the crossbar for smooth drainage of rainwater, foreign substances such as garbage or fallen leaves are easily introduced into the drainage hole, and the foreign substances introduced in this way are There was a problem in that it was deposited in the drainage ditch and eventually lowered the drainage capacity of the ditch.

In addition, there is a problem in that the pedestrian's shoes or the heel of the shoe are caught in the drain hole formed in the conventional grating, causing a safety accident in which the pedestrian falls.

In order to solve the above problems, a method of covering a cover having a small drainage hole on the top of the grating has been developed, but in the past, the coupling structure and method of the cover for the grating and the grating are complicated or the bonding strength is poor, and there are practical problems in production and use. There were many.
