Description

Grating cover for drain that is easy to fasten {GRATING COVER FOR DRAIN HOLE FOR EASY FASTENING}

The present invention relates to a grating cover for a drain. More specifically, it is mounted on a step formed at the entrance of the drain to prevent the inflow of foreign substances, and has a plurality of width frames and a plurality of longitudinal frames spaced at regular intervals inside the rectangular frame. In the grating cover for a drain that is seated on a grating that is combined in a grid form, it is made of a square flat plate-shaped body corresponding to the grating so as to be seated on the upper surface of the grating and cover the upper surface of the grating, and the discharge water on the road A cover body formed on the surface with a plurality of drain holes for draining water through the lower grating and a plurality of foreign matter filtering holes for blocking large and small foreign substances from passing through the lower grating and entering the drain hole; Each of the four corners of the cover body is formed in a rectangular shape with a predetermined width and length, and the cover body is formed by cutting both sides in the longitudinal direction and cutting only one side in the width direction so that it can be bent vertically. It relates to a grating cover for a drain that is easy to fasten and includes a U-shaped fastening piece.

Generally, a drain is formed at the edge of the road in the width direction so that rainwater from the road can be discharged. The drain is connected to a sewer pipe, so that rainwater from the road is discharged into a river, etc. through the drain. At this time, a grill-shaped grating is installed at the entrance of the drain to prevent the inflow of foreign substances from the road without interfering with the flow of discharged water such as rainwater.

However, this grating has a grid frame structure and can prevent the inflow of relatively large foreign substances, but cannot prevent the inflow of relatively small foreign substances due to the nature of the grid frame structure.

Therefore, even if a grating is installed in the drain, various foreign substances of relatively small size, such as cigarette butts and tree branches, enter the drain through the grating in the form of a grid frame, causing blockage of the drain. .

To prevent this problem, a grating cover that can be separately mounted on the top of the grating has recently been disclosed.

The conventional grating cover is formed in a flat shape to cover the upper part of the grating, and has a relatively small drain hole to prevent even small-sized foreign substances such as cigarette butts from entering the drain. It can be prevented more effectively, and cleaning work is convenient, so the exterior of the drain can be kept cleaner.

However, since these conventional grating covers are installed simply on top of the drain, they are easily separated by external force when a vehicle or pedestrian passes over them due to the gap that exists between the drain and the grating cover, causing human and material damage. This can occur, and in particular, in the case of pedestrians, a safety accident can occur where the pedestrian slips and falls due to their weight.

Accordingly, there has been a need for a grating cover that can be fastened to the grating in the relevant technical field, and in recent years, various grating covers that meet this need have been disclosed.

However, the conventionally disclosed grating cover required separate auxiliary materials such as fixing clips or bracket caps for fastening to the grating, and separate dedicated equipment or tools for constructing them. These auxiliary materials served as a factor in increasing the construction cost of the grating cover, and when bulky and heavy equipment had to be used depending on the type of auxiliary materials, there was a problem that manpower and time were unnecessarily consumed to transport the equipment.

A cover body having a plurality of drain holes for draining water through the grating and a plurality of foreign matter filtering holes formed on the surface to block large and small foreign substances from passing through the lower grating and flowing into the drain hole; Each of the four corners of the cover body is formed in a rectangular shape with a predetermined width and length, and the cover body is formed by cutting both sides in the longitudinal direction and cutting only one side in the width direction so that it can be bent vertically. Including a U-shaped fastening piece, the U-shaped fastening piece is bent vertically downward, and the fastening piece penetrates between the width-direction frames of the grating so that the fastening piece is in close contact with the outer peripheral surface of the width-direction frame, The cover body is fixed to the grating by bending the fastening piece in a ∪ shape so that it surrounds the frame in the width direction, enabling quick and easy fastening to the grating using only the fastening piece provided on the cover body without separate dedicated equipment and auxiliary materials. Do it as

In addition, in the present invention, the drain hole is made to have an uneven feel by embossing the hole to prevent pedestrians from slipping due to rain, snow, or foreign substances when they pass over the grating cover.

In addition, in the present invention, the grating cover is characterized in that a film is formed by zinc plating to prevent corrosion due to condensation or rainwater.

In the present invention as described above, the U-shaped fastening piece provided in the cover body is bent downward and brought into close contact with the outer peripheral surface of the width direction frame of the grating, and then the end is bent in the shape of ∪ to secure the cover in a way that surrounds the width direction frame.

Hereinafter, a grating cover for a drain that is easy to fasten according to the present invention will be described in detail with reference to the attached drawings.

First, in the present design, the grating (10) is a normal thing supported by a step (2) formed at the entrance of a drain (1) formed at the width direction edge of a road, such as a road, park, subway, or residential complex, As shown in FIG. 1, a plurality of width frames 12 and a plurality of longitudinal frames 13 are connected in a grid form at regular intervals inside a rectangular frame 11. In the drawing to help understand the present invention, The shape of the grating is not limited to the scope of the present invention.

The present invention relates to a grating cover coupled on top of the grating, and in particular, its technical feature is that it can be quickly and easily fastened to the grating without separate dedicated equipment and auxiliary materials.

Figure 2 is a schematic illustration showing a grating cover for a drain that is easy to fasten according to the present invention.

As shown in Figure 2, the present invention is provided with a cover body 110 that is seated on the upper surface of the grating.

The cover body 110 is a square, flat plate-shaped body corresponding to the grating so as to cover the upper surface of the grating, and is formed to a predetermined thickness to prevent deformation or damage due to external force.

The cover body 110 may be made of various materials, but it is preferably made of a metal material (for example, stainless steel) that can be used for a long period of time and has strength such that the fastening piece, which will be described later, can be elastically bent.

A drain hole 111 and a foreign matter filtering hole 112 are formed on the surface of the cover body 110.

It is preferable that the drain holes 111 are arranged in a plurality along the horizontal or vertical direction on all sides of the cover body to allow discharge water discharged from the road to drain into the drain through the lower grating.

The foreign matter filtering holes 112 are arranged in plural numbers along the horizontal or vertical direction on all sides of the cover main body, and may be formed in an appropriate shape to block large and small foreign substances from passing through the lower grating and entering the drain. The shape of the foreign matter filtering hole 112 is not limited to the scope of the present invention. For example, the foreign matter filtering hole 112 is formed in a long and narrow rectangular shape as shown in Figure 2 to filter out foreign matter of various sizes. Of course, it can also lead to the drainage of effluent discharged from the road.

Additionally, the present invention may include a bending plate 130 that is bent vertically downward from both edges of the cover body 110.

In general, the grating is narrower and shorter than the drain so that it can be smoothly inserted into the drain, so there is a certain amount of space between the four sides of the grating and the inner wall of the drain. The bending plate 130 is inserted between the side wall of the drain and the inner wall of the grating to fix the cover body, and prevents the cover body seated on the grating from shaking forward and backward due to external force.

Meanwhile, the bent plate 130 may be formed at one corner or a pair of opposing corners of the cover body. Typically, the drain 2 is standardized to a certain width and length, but in the case of some drains, it may be formed slightly wider or narrower during the construction process, so the bent plate 130 is formed at one corner or both opposite corners. It can be.

Next, the present invention includes a fastening piece 120 formed at a corner of the cover body.

The fastening pieces 120 are formed at each of the four corners of the cover body, and are respectively coupled to the four corners of the grating 10 disposed below.

The fastening piece 120 is formed in a rectangular shape with a predetermined width and length at the four corners of the cover body 110, and is cut in parallel on both sides of the cover body in the longitudinal direction so that it can be bent up and down. It is formed by making an incision on only one side.

Figures 3a) to 3d) are schematic illustrations showing the process of constructing the grating 10 according to a preferred embodiment of the present invention.

First, in the present invention, the fastening piece 120 at each corner is bent vertically downward, as shown in Figure 3a). At this time, the cover body is preferably disposed in an inverted state so that the fastening piece 120 does not interfere with the ground when the fastening piece 120 is bent.

Next, the grating 10 is seated in close contact with the bottom surface of the cover body 110, as shown in FIG. 3b). At this time, the fastening piece 120 disposed perpendicularly from the cover body 110 penetrates between the width direction frame 12 and the width direction frame 12 of the grating and protrudes to the outside of the grating.

Next, as shown in FIG. 3c), the grating 10 is moved forward, backward, left and right on the cover body so that the width direction frame 12 is in close contact with the fastening piece 120, and then the end thereof is cut as shown in FIG. 3d). Bend it into a ∩" shape and secure it in a way that surrounds the frame in the width direction.

Thereafter, the mutually fastened grating 10 and the grating cover 100 are turned over and the cover body 110 is placed on the upper side of the grating and then placed on the step 2 of the drain 1 to complete construction.

Figures 6a) to 9b) are exemplary diagrams showing a grating cover fastened to the grating through a separate fastener.

First, the safety cover (prior art 1) shown in 6a) to 6c) includes a grating cover 10, a bracket cap 30 fitted between the frame of the grating 20, and a fastening hole of the grating cover ( It includes a fastening means for fastening the bracket cap 30 through 1). The bracket cap, which is a separate subsidiary material, acts as a factor in increasing the construction cost, and the bracket cap must be inserted and fixed between the frames of the grating. The work process is complicated and cumbersome. In addition, if the bracket cap is separated from the frame of the grating due to various factors, there is no way to fix the grating cover (10), so loss of the grating cover is inevitable, and separate manpower and costs are incurred for maintenance and repair. Problems may arise.

Next, the grating cover (prior art 2) shown in FIGS. 7a) to 7c) is placed on the grating and is fitted between the grating cover 10 in which the circular iron plate 16 is embedded, and the grid 21 of the grating. It includes a magnetic bracket (30), and the grating cover and the magnetic bracket are coupled by mutual magnetic force. The magnetic bracket, which is a separate subsidiary material, acts as a factor in increasing the construction cost, and a circular steel plate is embedded in the grating cover. Because a separate work process is added for this, the manufacturing cost increases. In addition, the work process is complicated and cumbersome because the magnetic bracket must be fixed between the grids of the grating. In addition, since the simply magnetic coupling structure can be easily separated when a strong external force is applied, problems such as loss of the grating cover and additional manpower and costs for maintenance and repair may occur.

Next, in the grating auxiliary cover (prior art 3) of FIGS. 8a) to 8c), the auxiliary cover 20 mounted on the grating 10 is fastened with a C-shaped fixing clip 30, and the fixing clip is an auxiliary material. It is impossible to fasten the grating (10) and the auxiliary cover (20) without (30), and in order to adjust the position of the fixing clip (30) during the fastening process, a detachment assistant of reference numeral "A" shown in FIG. 8c) is used. The rod (A) is absolutely necessary, and the manufacturing price is bound to rise with the production of these fixing clips and tools dedicated to the fixing clip, which increases the purchase cost for consumers. In addition, there is no way to control the fixing clip without a detachable auxiliary rod, so construction is complicated and cumbersome.

Next, the grating safety cover assembly (prior art 4) of FIGS. 9a) and 9b) is coupled to a grating safety cover 100 disposed on the upper surface of the grating 20, and the grating safety cover and the grating are closely pressed to each other. By including the bracket 200, there is a problem in that the manufacturing cost and purchase cost increase due to the production of the coupling bracket, which is essential as an auxiliary material.

As such, conventionally disclosed grating covers must use dedicated subsidiary materials (fixing clips, bracket caps, magnetic brackets, etc.), and in the case of some grating covers, special fastening tools must be used, which has the problem of significantly lowering economics and workability. In addition, although not shown in the drawing, in the case of the prior art of fastening the fixing clip connecting the grating and the grating cover with a rivet, a rivet gun and compressor must be prepared to construct the rivet. Due to the nature of the items that must be installed while moving along the drain, if a bulky and heavy compressor must be used, workability is bound to be significantly reduced.

The grating cover 100 according to the present invention bends the fastening piece 120 vertically using a tool (for example, a chisel) with a wide end and a flat end, and then bends the end with a tool such as pliers to form a widthwise frame ( After fixing in 12), the locked end can be firmly fixed by pressing strongly with a tool. In other words, compared to the prior art, the present design can be constructed using only small, light, and easily portable tools, thereby significantly reducing work time and construction costs. On the other hand, when constructing the present design, the worker may directly bend or bend the fastening piece 120, but the worker may be injured by the sharp edge of the fastening piece 120 during the work process. This is not desirable because sufficient binding force cannot be secured when bending the end and fixing it to the frame in the width direction.

Next, as shown in FIGS. 4a) and 4b), the drain hole 111 according to the present invention may be formed to protrude upward by embossing the hole. When the drain hole 111 is embossed, it has an uneven feel, preventing pedestrians from slipping due to rain, snow, or foreign substances when passing over the grating cover. The drain holes formed in the conventional grating cover were all intended for simple drainage, so they were formed by simply perforating the surface, and therefore, it was impossible to prevent slipping due to rain, snow, or foreign substances when passing over the existing grating cover. The grating cover 100 according to the present invention can prevent the above-mentioned problems by embossing the drain hole 111 to give it an uneven feel.

In addition, the grating cover 100 according to the present invention can be formed with a zinc plating film to have corrosion resistance and corrosion resistance, and thus can be used for a longer period of time by preventing corrosion due to condensation or rainwater.

The present invention, made as described above, enables quick and easy fastening to the grating using only a fastening piece provided on the cover body without separate dedicated equipment and auxiliary materials, and those skilled in the art can use this invention within the scope of the spirit and scope of the present invention. Sufficient changes, conversions, substitutions, and substitutions may be made taking into account the description of the design, and it is not limited to the above-described embodiments.
