Description

GRATING AND SAFETY COVER FOR GRATING JOINT CONNECTOR

The present invention relates to a grating and a safety cover fastening member for grating as a safety cover fastening member for gratings and gratings, which fastens a grating installed in a drain hole and a ventilation hole, and a grating safety cover fixedly installed on the grating.

In general, a drain hole is formed at the edge of the road in the width direction so that rainwater of the road can be discharged. The drain may be connected to a sewer pipe so that rainwater from the road may be discharged into a river or the like through the sewer. At this time, the grating in which the frame is formed in a lattice shape is seated at the entrance of the drain hole to prevent the inflow of foreign substances from the road without interfering with the flow of discharged water such as rainwater.

The grating is a lattice frame structure and can prevent the inflow of relatively large foreign substances, but cannot prevent the inflow of relatively small foreign substances such as cigarette butts and tree branches. Therefore, even if the grating is installed in the drain hole, various foreign substances may flow into the drain hole, which may cause clogging of the drain hole.

To prevent this problem, a separate grating safety cover may be installed on the top of the grating. The grating safety cover may be formed in a shape that can cover the upper portion of the grating so that a relatively small size drain hole is formed so that a small size foreign material is not introduced.

In addition, the grating safety cover may be provided to prevent safety accidents such as getting caught in the shoes of people passing over the grating.

Conventionally, a separate string, wire, copper, or the like is used to fasten the grating safety cover to the grating. In this case, after separating the grating from the ground, a process of fastening the grating safety cover to the grating using a string, wire or copper may be performed.

This can be cumbersome in that the grating must first be removed from the ground before the grating safety cover can be installed. In addition, the heavy weight of the grating may make manual separation more difficult.

In addition, when the grating and the grating safety cover are fastened using a string or wire, when a heavy object such as a truck repeatedly passes through the upper part of the grating, it may not be able to accommodate the deformation due to the load and may be damaged.

On the other hand, copper may be used as a fastening means to accommodate deformation due to load. However, in the case of copper, there is a problem that the installation cost increases due to the high cost.
