Description

Safety Grating

The present invention relates to a grating used as a cover of a drainage channel installed in a park or a school playground, and more particularly, by fixing an elastic body of rubber material on a steel support constituting the grating, thereby preventing safety accidents due to lattice through holes. The present invention relates to a safety type grating which can prevent the sliding accident by frost or ice at the same time.

In general, the grating is installed in drains such as roads, parks, and sports grounds, and serves as a cover, and serves to prevent various wastes such as fallen leaves from flowing into the drains. In addition, large gratings may be installed in a ventilation duct of a subway to perform a ventilation function.

The grating is mainly formed of steel to secure rigidity, and in some cases, stainless steel or a plated product may be used to prevent rust.

Figure 1 shows an example of a typical small steel grating installed in a drain, such as a road or a park.

Typical steel gratings, as shown in Figures 1 and 2, a plurality of bearing bars 101 arranged in parallel to be spaced apart at regular intervals, and the bearing bar 101 of the bearing bars 101 are interconnected A plurality of cross bars 103 installed to be orthogonal to the bearing bar 101 on the upper side of the bearing bar 101 so that the pair of flat plates 102 and the bearing bar 101 attached to both ends are not twisted by a load. It consists of).

The bearing bar 101 and the cross bar 103 are arranged in a lattice structure to form a plurality of through holes 104 through which rainwater flows.

By the way, the conventional general grating shown in FIG. 1 and FIG. 2 has a problem that the safety | security of a pedestrian is not considered at all because the main objective is to ensure the drainage function.

Therefore, in the case of the grating installed on the road, it is pointed out that women's high heels fall into the through hole 104 and a safety accident occurs. In the case of steel gratings installed in parks or schools, the risk of such accidents is further increased.

In particular, there are many people who use the park to exercise by bicycle or inline skating. According to the conventional steel grating structure, a safety accident that often causes the wheel or inline skate of the bicycle to fall or stumble in the through hole of the grating often occurs. have.

For example, if a child jumps and stumbles through the through hole of the steel grating, he / she will be bruised by steel grating. In addition, the weak elderly and those who are uncomfortable are sometimes stepped on by the through-holes of steel grating.

In addition, in the case of infants, because the foot is small, the foot falls into the through hole of the steel grating. In addition, the wheel of the baby carriage carrying the infant may be pinched by the through hole of the grating, which may make driving difficult.

In order to improve this point, a grating has been proposed in which a supporting plate is formed at the bottom of the steel grating through-hole so as to reduce the size of the steel grating through-hole or to prevent women's high heels from falling out.

However, there is a problem that steel grating of such a structure is difficult to manufacture and expensive to manufacture.

In addition, the conventional steel grating is fundamentally slippery since the material is formed of steel, and particularly, when frost or snow is frozen in winter, pedestrians slip and are more likely to be in an accident.

Basically, the steel is smooth, so the pedestrian can slip because the surface is smooth. If the frost falls or the ice freezes, the surface becomes very dangerous. In particular, when gratings installed in parks are in such a dangerous state, the possibility of accidents among those who exercise in the parks is further increased.

As a way to improve this problem, a method of bonding an elastic material of rubber material to the upper surface of the steel grating with an adhesive can be considered.

When the elastic body such as rubber is bonded to the upper surface of the steel support, it is possible to improve the convenience of pedestrians, and to prevent people from performing various accidents from slipping in advance.

However, the method of bonding the rubber elastic body to the steel support has the following problems.

First, the steel material and the rubber material is difficult to fully bond due to the difference in physical properties.

In other words, steel and rubber are very difficult to be perfectly combined even by bonding with a strong adhesive due to differences in their chemical and physical properties.

Second, even if the rubber is bonded to the steel support using an adhesive, the adhesive force is difficult to last long due to rain.

That is, when there is much rain, such as during the rainy season, there is a high possibility that water penetrates between the steel support and the rubber and weakens the bonding force.

Third, the steel material and the rubber material is different from the expansion rate and shrinkage rate, so the rubber is easily released from the steel support in cold winter or hot summer.

In climatic conditions such as in Korea, where the temperature decreases a lot in winter and becomes high in summer, the likelihood of the rubber elastomer to deviate from the steel support becomes very high.

The present invention has been made in view of the above problems, and is intended to provide a safety type grating focusing on the safety of pedestrians and users by avoiding the conventional grating concept of performing a drainage function.

In particular, the present invention is characterized in that the steel support and the rubber elastic body can be structurally firmly coupled.

The present invention has been proposed to solve the above-described problems, and in the grating installed in a park or various sports facilities, the present invention provides a safety type grating which can prevent pedestrians from falling or tripping over the through hole of the grating. Its purpose is to.

Still another object of the present invention is to provide a safety type grating capable of freely riding a bicycle or inline skates in a park, and preventing wheels such as strollers from falling into the through holes of the grating.

Still another object of the present invention is to provide a safety type grating which can prevent accidents by preventing slipping even if ice is formed due to frost or snow accumulation.

Still another object of the present invention is to provide a safety type grating capable of structurally and firmly bonding a rubber elastic body on a steel support to prevent the elastic body from being separated during use.

Another object of the present invention is to intentionally form a burr by drilling a hole from below into a flat plate installed on the upper surface of the steel support, and then press the elastic body to insert the burr into the elastic body. It is to provide a safety type grating to increase the bonding force of the elastic body.

Still another object of the present invention is to provide a safety type grating that can be suitably used for a purpose by changing the structures of the steel support and the elastic body according to the use.

Still another object of the present invention is to provide a safety type grating capable of preventing slip accidents by forming grooves or embossing protrusions on the upper surface of the elastic body provided on the steel support.

Safety grating of the present invention for achieving the above object is a steel support consisting of a pair of I bars spaced at regular intervals; A plate installed on an upper portion of the steel support; It is made of an elastic body attached to the flat plate, the insertion groove which is coupled to both ends of the flat plate is provided at both ends of the width direction of the elastic body, by pressing the upper surface of the elastic body after inserting the elastic body to the flat plate, When the hole of the intentionally formed burr is inserted into the elastic body, the elastic body and the plate is characterized in that coupled to each other.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the safety type grating of the present invention.

First Embodiment

3 to 5 show a first embodiment of the present invention. Figure 3 is a block diagram of a safety type grating according to the first embodiment of the present invention, Figure 4 is a block diagram showing the coupling form of the flat plate and the elastic body of the main part of the present invention, Figure 5 is a flat plate and the main part of the present invention It is a block diagram which shows the other coupling | bonding form of an elastic body.

In the first embodiment of the present invention, a flat plate is basically provided on a pair of I bars, and a rubber-like elastic body is bonded onto the flat plate. In the first embodiment, since a separate flat plate is provided on the I-bar, it can withstand high loads such as a vehicle.

Safety type grating according to the first embodiment of the present invention, the steel support 10 consisting of a pair of I bars 11 spaced at regular intervals; A flat plate 20 installed on the steel support 10 and having a plurality of holes 25 drilled from the bottom thereof; It is coupled to the flat plate 20 is provided with an angled groove 31 at both ends of the width direction is made of an elastic body of rubber material 30 so that both ends of the flat plate 20 can be inserted.

In this case, when the hole 25 is drilled in the flat plate 20, a burr 26 is intentionally formed, and the burr 26 penetrates and inserts the elastic body 30 by pressing the elastic body 30. By doing so, the elastic body 30 and the flat plate 20 are coupled to each other.

In general, when a hole is drilled in a flat plate, a burr is generated around the perforated hole. In the present invention, the burr is not removed but the burr is well generated and the elastic body is pressed to insert the burr into the elastic body. It has its features.

When drilling holes in the flat plate 20, it is preferable to design upper and lower dies (not shown) so that burrs are easily generated.

As shown in FIG. 9A, when the elastic body 30 is simply inserted into the flat plate 20, the elastic body is caused by the frictional force between the vehicle wheel 40 and the rubber elastic body 30 when the vehicle or the like passes through. 30 may be pushed in the horizontal direction, and in severe cases, the elastic body 30 may be separated from the flat plate 20.

However, when the burr 26 is formed on the flat plate 20 as shown in the present invention to compress the flat plate 20 and the elastic body 30, as shown in FIG. It is inserted into the elastic body 30 to be in a state of supporting the elastic body 30. Accordingly, even if the wheel 40 of the vehicle passes through the grating, the phenomenon in which the elastic body 30 is pushed or detached in the horizontal direction does not occur.

In addition, as shown in FIG. 5, a protrusion 35 is inserted into the hole 25 of the flat plate 20 in the lower portion of the elastic body 30 so that the elastic body 30 and the flat plate 20 are formed. It is more desirable to be combined.

If the elastic body 30 is provided with a projection and the projection is inserted into the hole of the flat plate 20, the elastic body 30 and the flat plate 20 are more firmly fixed.

In addition, a plurality of grooves 33 in the longitudinal direction may be formed on the upper surface of the elastic body 30, or a plurality of embossing protrusions 32 protruding upward may be formed. Various patterns may be formed on the upper surface of the elastic body 30 to improve aesthetics or display various information such as guide signs.

The safety type grating according to the first embodiment of the present invention configured as described above allows the burr to be well formed when the hole is drilled in the plate, and presses the elastic body assembled on the upper side so that the burr is assembled on the upper side. It was inserted into the inside.

Hereinafter, a manufacturing process of the safety type grating according to the first embodiment of the present invention will be described.

First, a plurality of holes 25 are drilled in the flat plate 20 from below, so that the burr 25 protrudes from the top surface of the flat plate 20.

Subsequently, the flat plate 20 is welded and fixed to the top of the steel support 10 having a pair of I bars 11 spaced apart at regular intervals. At this time, the flat plate 20 is welded such that both ends of the flat plate 20 protrude out of the I bar 11. This is for the insertion groove 31 of the elastic body 30 to be fitted to the protrusion of the flat plate (20).

Thereafter, an adhesive is applied to the flat plate 20 and an elastic body 30 of rubber material is installed, and then the elastic body 30 is pressed.

That is, both ends of the flat plate 20 are inserted into the insertion grooves 31 formed at both ends of the elastic body 30, and the upper surface of the elastic body 30 is pressed to press. Then, the burr 26 of the flat plate 20 is inserted into the bottom surface of the elastic body 30 and the flat plate 20 and the elastic body 30 are combined to form one unit grating.

Thereafter, a plurality of unit gratings are arranged side by side such that a slight gap exists between the elastic bodies 30 to produce a total grating having a required size.

Accordingly, the rain water flows to the lower portion of the steel support 10 through the gap between the elastic body 30 and the elastic body 30, and the large volume of dirt is blocked. That is, the gap between the elastic body 30 and the elastic body 30 serves as the through hole 104 (refer to FIG. 1) of the conventional grating.

According to the present invention, since the gap between the elastic body 30 and the elastic body 30 performs a drainage function, the water drainage function is slightly inferior to the conventional grating. This is the result of the present invention focused on the safety of pedestrians.

However, the lowering of the drainage function as described above can be sufficiently overcome by forming a long grating. That is, if the steel grating is installed intermittently without extending the installation or extending the installation section of the grating as in the prior art, the deterioration of the drainage function can be easily solved.

According to the present invention, since the rubber-like elastic body 30 is installed on the upper portion of the steel support 10, the through-holes as in the prior art are eliminated, and the possibility of a safety accident is very small.

In addition, since only the elastic material of the rubber material is exposed to the outside, even if the foot falls into the gap between the elastic body 30 and the elastic body 30, there is no fear of accident.

In addition, since only the elastic material 30 of rubber material is exposed instead of steel material, frost or ice is not formed well even in winter, so it is safe. Furthermore, since the groove 33 and the embossing projection 32 are formed on the surface of the elastic body, the slip accident can be prevented at the source.

The safety type grating of the first embodiment is suitable for high load grating on the side of the road because the flat plate 20 is installed on the steel support 10 made up of a pair of I bars 11 spaced at regular intervals. Do.

Second Embodiment

In the second embodiment of the present invention, the elastic body is directly bonded to the horizontal plane of the T-shaped structure or angle without using a separate flat plate as in the first embodiment.

In the second embodiment of the present invention, as shown in Fig. 6, the steel support is composed of a T-shaped structure 15 having a horizontal portion in which a plurality of holes are drilled from below or a pair of angles 16 in which the vertical portions are opposed to each other. 10; Comprising an elastic body 30 is coupled to the horizontal portion of the steel support 10, both ends of the horizontal portion of the steel support 10 is inserted into the insertion groove formed in the width direction both ends of the elastic body 30, the steel When the holes 15 'and 16' are formed in the horizontal portion of the support 10, a burr intentionally formed is inserted into the elastic body 30, and the elastic body 30 and the horizontal portion are coupled to each other. have.

(A) and (b) in FIG. 6 show the use of the T-shaped structure 15 as the steel support 10, and (c) and (d) are the steel support 10 as a pair of angles 16. It shows that using.

Also in this case, a plurality of grooves 33 in the longitudinal direction are formed on the upper surface of the elastic body 30 or a plurality of embossing protrusions 32 protruding upward are formed.

In Figure 6 (a) and (c) shows that a plurality of grooves 33 are formed on the upper surface of the elastic body 30, (b) and (d) is a plurality of embossing projections on the upper surface of the elastic body 30 (32) is formed.

As such, when the T-shaped structure 15 or the angle 16 is used as the steel support 10, the steel support 10 supports the elastic body 30 only at the central portion.

Therefore, since it can support a small load compared with the case where I bar is used as a steel support body, it is suitable for light load grating. Other matters are basically the same as the first embodiment, so detailed description thereof will be omitted.

Third Embodiment

The third embodiment of the present invention is a grating used for pedestrians only, Figure 7 is a block diagram showing a third embodiment of the present invention, Figure 8 illustrates the operational relationship of the pedestrian safety grating of Figure 7 It is for reference only.

In the third embodiment of the present invention, as shown in Figures 7 and 8, the elastic portion 37 having a greater elastic force than the other portion is located in the center of the elastic body 30, thereby pedestrian-only It is formed by the structure.

At this time, the elastic portion 37 is preferably formed thicker than the other portion or formed in an air tube structure.

In particular, as shown in (a) and (b) of FIG. 8, the steel support 10 supporting the elastic body 30 is formed of a pair of angles 16 spaced apart at regular intervals, and the elastic portion By allowing the 37 to be positioned between the horizontal portions of the angle 16, the elastic force can be further increased.

Of course, as shown in (c) and (d) of FIG. 8, even when the elastic body 30 is coupled to the general T-shaped structure 16, the same effect can be obtained.

This type of safety grating can be used only for pedestrians to obtain the elasticity effect of the elastic portion 37, it is suitable for gratings installed in parks or sports fields.

The greatest feature of the present invention is that safety is focused on the conventional grating concept that is focused on drainage.

Therefore, when the grating according to the present invention is installed in a park or a playground, it is possible to prevent various safety accidents caused by the conventional steel grating.

According to the present invention, since the drainage function is deteriorated because the drainage is made only by the distance between the elastic body and the elastic body, this problem can be easily solved by installing a plurality of gratings in the drainage path.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those skilled in the art may appropriately change within the scope described in the claims of the present invention.
