GRATING SAFETY COVER CAPABLE OF BEING FIXED BY THE MOUNT CLAMP

The present invention relates to a grating safety cover, and more specifically, by forming a double tornado-type running water induction path in different directions centering on the central main drain part on the upper surface to facilitate the inflow of running water to the main drain part, By forming drainage holes inside and outside the induction path, and lowering the height of the area adjacent to the induction passage, it is fixed by a mount clamp that drains the water flowing along the induction passage and the overflowing water in the induction passage. Possible grating safety covers.

Steel grating is mainly installed on the upper surface of narrow and long drainage channels of '∪' cross section installed in school grounds or parks, etc. The grating bars are welded to the end bars in the form of a square frame at equal intervals in the longitudinal direction, and the grating bars are horizontally attached to the grating bars It is made in the form of a plate in which a cross bar for fixing is formed. When a steel grating is installed in a drain, rainwater or sewage is easily discharged, and people's feet and objects do not fall out. However, in order to solve the problem of small items such as women's heels or stroller wheels being caught between the grating bars of the steel grating due to the large spacing between the grating bars of the steel grating, the steel grating is covered with a plate with a small hole to maintain water drainage and A grating safety cover is used to prevent items from falling out.

Conventional steel grating safety cover is a lower perforated plate having rigidity, for example, a polycarbonate perforated plate, and an upper perforated plate having elasticity, for example, a multi-layer perforated plate in which a polyurethane perforated plate is bonded to each other is used.

As an example of such a steel grating safety cover, Korean Patent Registration Nos. 10-1013089 (Grating safety cover and manufacturing method thereof), No. 10-1802360 (Grating safety cover mounting structure and method), No. 10-1766367 (Grating safety cover) assembly) is disclosed.

The grating safety cover and its manufacturing method include the steps of forming a perforated plate 10 having a plurality of holes 30 penetrating vertically as shown in FIG. 1 ; Inserting a semi-conical column 41 having a smaller diameter than the hole into each of the plurality of holes, inserting the outer peripheral surface of the column and the inner peripheral surface of the hole to be spaced apart; forming an upper layer by applying a material for forming an upper layer on an upper portion of the perforated layer while the semi-conical column is inserted; It provides a method of manufacturing a grating safety cover comprising the step of separating the semi-conical-shaped pillar, has a structure that does not easily fall out such as heels, stroller wheels, and other objects while draining well, and is durable due to the shock absorption function of the elastic body This provides a safety grating that is strong and not easily damaged.

The grating safety cover mounting structure and method is as shown in FIGS. 2 and 3, in the grating safety cover mounting structure: a cross bar 130 installed across a plurality of grating bars 120 spaced apart from each other and arranged adjacent to each other ) with a steel grating 110; The safety cover 200 is seated on the upper portion of the steel grating and has a plurality of drain holes 232 and a first fastening hole 240 and a second fastening hole 250 formed with the crossbar positioned therebetween. ); and a grating safety cover fastening device 300 for fixing the safety cover to the cross bar.

The grating safety cover assembly is a grating safety cover assembly coupled to a grating-shaped grating mounted on a step of a road drain as shown in FIG. 4, it is disposed on the upper surface of the grating 20 and the entire area of the upper surface of the grating It is formed in a flat plate shape to cover the grating safety cover 100 in which a plurality of drain holes 110 are formed so that the discharge water of the road passes; and a coupling bracket 200 for pressing the grating safety cover and the grating in close contact with each other so that the grating safety cover is coupled and fixed to the upper surface of the grating.

However, the grating safety cover and its manufacturing method use expensive molding materials such as polycarbonate and polyurethane, as well as molding and bonding the upper part and the lower part separately, so that the manufacturing and delivery unit cost is high. In addition, when exposed to the outdoors for a certain period of time, peeling of the upper perforated plate and the lower perforated plate occurs, and periodic replacement is required, thereby causing a financial burden.

In addition, the grating safety cover mounting structure and method and the grating safety cover assembly have problems in that drainage holes are formed in a predetermined pattern, so drainage is not smoothly induced, and the durability of the cover fastening device or coupling bracket is relatively weak.
