Description

{Grating Cover Assembly}

The present invention relates to a grating safety cover assembly. More particularly, in the process of coupling the grating safety cover to the upper part of the grating resting on a road drainage hole, a separate engaging bracket can be used to fix the grating safety cover so that separate engaging bolts and tools are unnecessary, The grinding operation can be easily performed and the grating can be separated as it is without removing the coupling bolts and the like even when the grating is to be separated from the drain hole so that the drain hole maintenance operation can be easily performed, The present invention also relates to a safety cover assembly for a grating which can be cleanly controlled and can prevent the risk of a safety accident.

Generally, a drainage hole is formed at the widthwise edge of the road so that rainwater or the like of the road can be discharged. The drainage hole is connected to the drainage pipe, and rainwater of the road is discharged to the river through the drainage hole. At this time, a grill-shaped grating is seated at the inlet of the drain hole so as to prevent foreign matter and the like from entering the road without interfering with the flow of drain water such as rainwater.

However, such a grating can prevent the inflow of foreign matter having a relatively large size as a lattice frame structure, but can not prevent the inflow of foreign substances having a relatively small size due to the nature of the lattice frame structure.

Therefore, even if a grating is installed in the drain hole, various foreign substances such as cigarette butts, branches and the like, which are relatively small in size, are introduced into the drain hole through the grating in the form of a lattice frame, thereby causing clogging of the drain hole .

In order to prevent this, recently, a separate grating safety cover is mounted on the upper part of the grating. The grating safety cover is formed in a flat plate shape so as to cover the upper part of the grating, and a small size foreign substance such as a cigarette butt And a drain hole is formed in a relatively small size.

By attaching a separate grating safety cover to the upper part of the grating, it is possible to more completely prevent foreign matter from being introduced into the drain hole, and also to clean the appearance of the drain hole with a convenient cleaning operation.

In order to mount the grating safety cover to the grating, a separate coupling bolt is generally used. At this time, since there is no space for fastening the coupling bolt in the grating, the coupling bolt passes through the grating safety cover and the grating, It is used in a way to extend to the jaw. Such a coupling bolt fastening operation is very inconvenient, and even when the grating is to be separated from the drain hole, there is a problem that the coupling bolt must be removed again and the maintenance work is very inconvenient.

Due to the inconvenience of this operation, a method of connecting the grating safety cover to the grating by using a separate strap or cable tie is used at the actual management site, which is not only inconvenient to work, There is a problem in that the appearance of the drain hole is also dirty.
