Description

[Revision under Rule 26 07.10.2009] Grating safety cover

The present invention relates to a grating safety cover, and more specifically, by installing a safety cover in the grating installed in the drainage for rainwater, playgrounds, parks, dwellings, etc., it is possible to filter dirt and contaminants, In this case, it is possible to prevent the loss of the rubber chip, which is a filler, to improve the urban environment in harmony with the surrounding environment by forming a beautiful appearance, and to prevent the wheels of in-line skates and strollers, etc. The present invention relates to a grating safety cover capable of safety, such as a safety accident that occurs to be taken out, a prevention of an injury from an accident such as being tripped over a grating or a fall due to a grating.

Generally, in order to prevent the overflow of rainwater, road drains, parks, and sports fields are formed with sewers formed of long passages for rapid drainage, and steel gratings are installed on the upper portions of the sewers for safety.

This steel grating is to ensure safety by installing a plurality of diaphragm to maintain a constant interval in the horizontal and vertical direction inside the rectangular rectangular frame.

However, the steel grating of the above structure may lose various drainages due to the inflow of sewage, cigarette butts, and other wastes into the sewer through the space between the diaphragms, and thus the drainage function may be lost, and the steel grating may be made of metal. In the exposed state, it is not only a factor that causes safety accidents due to shocks, but also the wheels of transportation vehicles such as strollers, wheelchairs, shopping carts, and suitcases may fall out, so when the vehicle passes over the grating, it is obliquely sideways. There is an inconvenience to pass through.

In addition, in schools, when children fall into a drain with a steel grating, coins or pencils fall into the drainage space formed by the steel grating's partitions, and injuries or jokes fall down and hit the steel grating. Structural improvement of the steel grating is absolutely necessary.

In order to prevent foreign matters from flowing through the steel grating, Utility Model Registration No. 20-230696, Steel Grating's dirt prevention net, Utility Model Registration No. 20-333116 Grating Interlocking Fine Mesh Screen, Utility Model Registration No. 20-385529 Excellent inflow It is known that the filth filtering device of the manhole, Patent Publication No. 10-2006-1907, elastic grating and its manufacturing method.

The utility grid registration No. 20-230696 of the grating prevention net is to form an elliptical hole and an uneven portion to prevent slipping so that small dirt does not penetrate, it is to be fixed using a bolt.

The above-mentioned Utility Model Registration No. 20-333116 grating interlocking mesh sieve frame is to install and manufacture the uneven type trivet mesh frame combined with the grating between the grating and the rain gutter.

The above mentioned utility model registration No. 20-385529 sewage filtering device of rainwater inlet manhole is installed in the lower part of the grating to install the primary filter network for filtering waste, and the secondary filter collection box for filtering the incoming soil under the grating It will be able to filter and collect various wastes flowing through.

Such steel grating can prevent dirt from flowing into the sewer in its own way, but as the frame and the diaphragm of the metal are exposed to the outside, the children's safety may be threatened if the child falls and bumps.

On the other hand, it relates to the above-mentioned Patent Publication No. 10-2006-1907 elastic grating and a method of manufacturing the same.

The steel grating has a colored rubber layer formed on the upper part of the rubber material, so that the steel grating described above can solve the factors that cause the wheel of the vehicle to fall out and hinder the aesthetics of the vehicle. In case of replacement factor, there was a big cost problem such as changing the whole grating.

Applicant has developed to solve the above problems, such as safety, economics, efficiency, economics of maintenance, aesthetics by installing a safety cover that is good inflow to the top of the grating installed in the sewer pipe.

The purpose of the present invention is to install a safety cover on the grating installed in the side runway pipe for rainwater inflow on the playground, especially artificial turf field, to prevent the loss of the rubber chip as a filler to reduce the cost due to the filler filling In providing.

Another object of the present invention is to install a safety cover on the grating installed in the sewer for rainwater, sports ground, park, residential area, etc. to form a beautiful appearance to improve the urban environment in harmony with the surrounding environment In providing a cover.

Another object of the present invention is to install a safety cover on the grate installed in the sewer for rainwater, playgrounds, parks, dwellings, etc., to prevent it from popping up when it is stepped on the existing graft, and to prevent injury from falling due to falling. To provide a grating safety cover that can be planned.

Another object of the present invention is to install a safety cover on the grating installed in the sewer for rainwater, playground, park, residential area, etc. It is possible to prevent injuries that occur, and to prevent the phenomenon of falling out of the stroller or shoe heel and the like to cope with safety accidents in advance.

The present invention for achieving the above object is seated in a rectangular manhole 11, the sewer 12 is formed on the road surface 10, and the seating portion 13 formed in the upper side of the manhole 11 and the horizontal direction and A grating safety cover installed in a grating 20 in which a plurality of drainage spaces 21 are formed by a diaphragm fixed integrally in a longitudinal direction to prevent a safety accident, which is installed on an upper portion of the grating 20, A perforated plate 30 having a drain hole 31 formed therein; Adhesively bonded to the upper portion of the perforated plate 30, the soft PVC mat 50, the rain hole 51 is formed in the center portion, and integrally formed on both sides of the soft PVC mat 50, the water is lower in the lower Grooves are formed at regular intervals so as to flow in, the EPDM chip and the urethane resin is mixed and compression molded, the grating characterized in that it comprises a safety cover 100 including an EPDM color chip 40 is a pattern formed on the upper side Provide safety covers.

In addition, the present invention is mounted on the rectangular manhole 11, the sewer 12 is formed on the road surface 10, and the seating portion 13 formed on the inner upper side of the manhole 11 and fixed integrally in the horizontal and vertical directions. In the grating safety cover is installed in the grating 20 is formed by a plurality of drainage space 21 is formed by the diaphragm to prevent a safety accident, is installed on the top of the grating 20, a plurality of drain holes 31 are formed Perforated plate 30; Adhesively bonded to the upper portion of the perforated plate 30, the soft PVC mat 50, the rain hole 51 is formed in the center portion, and integrally formed on both sides of the soft PVC mat 50, the water is lower in the lower Grooves are formed at regular intervals so as to flow therein, and provides a grating safety cover, characterized in that it comprises a safety cover 100 formed integrally with the artificial grass plate 60 to which the artificial grass 61 is attached.

The present invention can install a safety cover on the grate installed in the sewer for the rainwater inlet of the artificial turf, especially the artificial turf field, can filter the rubber chip as a filler and reduce the cost, and prevent the inflow of sewage to block the sewer. In addition, there is an effect that can prevent the backflow of odor.

In addition, by installing a safety cover on the grating installed in the drainage for rainwater, playgrounds, parks, dwellings, etc., the exterior is beautifully formed to harmonize with the surrounding environment to improve the urban environment.

In addition, by installing a safety cover on the grating installed in the sewer for rainwater, playgrounds, parks, dwellings, etc., there is an effect that can be prevented by jumping to step on the existing grating to promote safety.

In addition, the safety cover is installed on the grating installed in the sewers for rainwater, playgrounds, parks, and residential areas, and it is convenient for maintenance because dirt and impurities are not entered. It can prevent, can prevent falling of the stroller or shoe heel, etc., there is an effect that can prevent a large injury even fall.
