In particular, as foreign matter such as oil or rainwater accumulates on the surface of the deck, pedestrians slip and injure or traffic accidents due to water film phenomenon between the upper surface and the vehicle wheel frequently occur.

Therefore, in the conventional deck, a drain hole is formed in the bottom portion to smoothly remove rainwater and various foreign substances on the surface in rainy weather, or to prevent slipping accidents, anti-slip flooring is applied to the upper surface to prevent slipping. A method of forming the prevention layer has been used.

However, in the conventional deck, there is a problem in that the corrosion-resistant anti-slip flooring material is cured due to external force in the anti-slip layer in the process of forming a hole to communicate with the drain hole in the anti-skid layer formed by curing.

In addition, when the corrosion-resistant anti-slip flooring material is applied by inserting a sealing member in the drainage hole so as to prevent flow through the drainage hole in the application process, the sealing member is cured in the process of curing the corrosion-resistant anti-slip flooring material. There was a problem that it was difficult to separate due to adhesion.

Moreover, in the process of separating the sealing member from the drain hole, an excessive force acts on the anti-slip layer due to adhesive force, thereby causing damage such as cracks, thereby increasing the defect rate in the manufacturing process of the product and unnecessary maintenance and maintenance costs. There was a problem in that the economic efficiency and productivity was lowered.

At this time, the communication guide bar may extend integrally with a closed end corresponding to the diameter of the drainage hole 11a at the lower end of the body portion protruding inside the application space. In addition, the diameter of the closed end is set to be less than the diameter of the body, so that the closed end may be formed to be stepped radially inward from the outer surface of the body. Through this, when the closed end is inserted into the drain hole (11a), the torso may be locked and disposed inside the application space. In addition, the body portion may be formed to have a length corresponding to the predetermined height (h2), but may be provided with a coating film guide portion radially outward along the outer circumference to guide the coating thickness of the corrosion-resistant anti-slip flooring at the upper end. Through this, it is easy for the operator to uniformly form the coating thickness simply by applying the corrosion-resistant anti-slip flooring material so as to correspond to the coating film guide portion, and thus the manufacturing convenience can be further improved. Belongs to

On the other hand, as shown in Figures 1 to 5a, when the deck body portion 10, the corrosion-resistant anti-slip flooring and the manufacturing apparatus 150 is prepared (s10), the communication guide to the drain hole (11a) The deck body 10 is seated on an upper portion of the manufacturing apparatus 150 so that the bar 152 is inserted and protrudes (s20).

At this time, the communication guide bar 152 is preferably formed to have a diameter (d2) corresponding to the predetermined diameter (d1). Through this, the communication guide bar 152 can be stably inserted into the drain hole 11a, as well as the corrosion resistance through the inner circumference of the drain hole 11a and the outer circumference of the communication guide bar 152. The flow of anti-slip flooring can be minimized.

Meanwhile, as shown in FIGS. 1 to 5B, when the deck body portion 10 is seated on the upper portion of the manufacturing apparatus 150 so that the communication guide bar 152 is inserted and protrudes into the drain hole 11a. (s20), the anti-corrosion anti-slip flooring is applied and cured to the application space to form the anti-slip layer 20 (s30).

In detail, the anti-slip layer 20 is formed on the anti-slip layer 20 as it is pressed by the roller 1 for formation of irregularities in a state in which the corrosion-resistant anti-slip flooring material is applied to the coating space so that the anti-slip effect is further improved. Can be.

Here, the roller 1 for forming irregularities has a plurality of pressing protrusions 1b in the shape of a column arranged at predetermined intervals on the outer surface of the rotary body 1a. Of course, in some cases, spaced apart at predetermined intervals along the circumferential direction of the body portion 1a, it may be provided as a vertical or horizontal frame having a predetermined thickness.

And, before the corrosion-resistant anti-slip flooring material applied to the application space is cured, the unevenness forming roller 1 is rotated along the upper surface of the base 11. Through this, the concavo-convex forming layer z including the concave grooves x and the convex portions y corresponding to the end face shape of the pressing protrusion 1b may be formed on the upper surface portion of the anti-slip layer 20. Accordingly, the anti-slip flooring material is pressed against the end surface of the pressing projection 1b by the rotational force and load of the unevenness forming roller 1, so that it is in close contact with the upper surface of the base portion 11, so that the anti-slip layer The adhesion strength of (20) can be further improved.

Here, the length (h3) of the communication guide bar 152 is preferably set to correspond to the sum of the thickness (h1) and the predetermined height (h2) of the base portion (11). In detail, when the communication guide bar 152 is inserted into the drain hole 11a so that the base 11 is seated on the upper portion of the base plate 151, the upper end of the communication guide bar 152 is drained. It may protrude from the hole 11a and be disposed in the application space. That is, the upper end of the communication guide bar 152 may be exposed to the application space to have a height substantially corresponding to the predetermined height h2 of the side wall portion 12. Through this, the corrosion-resistant non-slip flooring material can be applied so that the upper surface of the communication guide bar 152 is exposed to form a communication hole 21a to be described later as it is disposed to penetrate the anti-slip layer 20 in the vertical direction. can do. In addition, the communication guide bar 152 guides the film thickness of the anti-slip layer 20 together with the side wall portion 12 so that when the worker applies the corrosion-resistant anti-slip flooring material, the anti-slip layer ( 20) As it is easy to form, the construction convenience and workability can be remarkably improved.

On the other hand, the communication guide bar 152 is substantially disposed inside the anti-slip layer 20 as the corrosion-resistant anti-slip flooring material is applied to the application space and cured. Therefore, the adhesive force of the corrosion-resistant anti-slip flooring material is applied to the outer surface of the communication guide bar 152. Since the corrosion-resistant anti-slip flooring material adheres to the contact surface during hardening, the release of the communication guide bar 152 is separated. Can be difficult.

At this time, the outer surface of the communication guide bar 152 is preferably provided with an anti-adhesive coating layer (152a) formed of a non-adhesive Teflon material to prevent adhesion of the corrosion-resistant non-slip flooring material. Accordingly, the communication guide bar 152 is prevented from being adhered to the outer surface of the anti-corrosion anti-slip floor by the anti-coating anti-slip coating layer 152a even after curing of the anti-corrosion anti-slip floor material is easily separated and manufactured. Convenience can be further improved. Moreover, since the communication guide bar 152 is stably separated from the anti-slip layer 20 without exerting excessive force on the deck body 10 for separation, damage such as cracks in the anti-slip layer 20 is prevented. Since it is prevented and unnecessary maintenance work and maintenance cost are not generated, economical efficiency and productivity can be further improved. Of course, in some cases, the anti-coating layer may be formed on the outer surfaces of the communication guide bar 152 and the base plate 151, and the corrosion-resistant anti-slip flooring material flowed from the upper portion of the deck body portion 10 may be used. The base plate 151 may be cured and adhered to the base plate 151 to facilitate the removal of the corrosion-resistant anti-slip flooring material. In addition, the communication guide bar 152 may be formed of a Teflon material, and since the adhesion of the anti-slip layer 20 can be prevented without a separate coating operation, productivity may be improved.

Meanwhile, as shown in FIGS. 1 to 5C, when the anti-slip flooring material is applied and cured to the application space to form the anti-slip layer 20 (s30). The communication hole 21a is formed so that the deck body 10 is separated from the manufacturing apparatus 150 and corresponds to the communication guide bar 152 on the anti-slip layer 20 (s40). In detail, the anti-slip flooring material is cured while being adhered to the upper surface of the base portion 11 and the inner surface of the side wall portion 12 as it is applied and cured to the application space to form the anti-slip layer 20. do. Here, since the communication guide bar 152 is in a state in which adhesion with the anti-slip layer 20 is prevented by the anti-adhesive coating layer 152a, the deck body 10 is smoothly moved upwards and stably separated. Can be.

At this time, when the deck body portion 10 is separated from the manufacturing apparatus 150, the non-slip layer 20 is formed with the communication hole 21a to correspond to the position of the communication guide bar 152. That is, the communication hole 21a corresponds to the communication guide bar 152 protruding so as to be exposed to the application space 11a as the communication guide bar 152 is separated and removed from the deck body part 10. It is formed as possible. Therefore, the communication hole 21a is formed to penetrate through the vertical direction of the anti-slip layer 20 but communicate with the drain hole 11a. And, as the drain hole 11a is formed, the production of the grating deck 100 coated with the corrosion-resistant anti-slip flooring may be completed. Accordingly, after the anti-slip layer 20 is formed, simply removing the deck body portion 10 from the manufacturing apparatus 150 without a separate process for forming the communication hole 21a, the communication hole ( Since 21a) is automatically formed, the production process can be simplified to further improve the productivity of the product.

As described above, since the rainwater and various foreign substances that accumulate on the surface in the rain through the communication hole 21a are smoothly removed on the upper surface of the anti-slip layer 20, traffic by pedestrian slipping or water film phenomena between vehicle wheels when moving between pedestrians and vehicles Since various safety accidents such as accidents are prevented beforehand, safety can be further improved. Moreover, the anti-slip layer 20 not only provides an anti-slip effect on its own, but also minimizes the water film phenomenon that may occur while the surface tension changes depending on the temperature, so the anti-slip effect of the road is significantly improved even in rainy weather, so the communication hole ( In addition to 21a), it is possible to provide a synergistic effect that can significantly improve safety.

On the other hand, Figure 6 is a cross-sectional view showing a modified example of the apparatus for manufacturing a grating deck coated with a corrosion-resistant anti-slip floor according to an embodiment. In this modified example, since the basic configuration excluding the communication guide bar and the buffer sealing member is the same as in the above-described embodiment, detailed description of the same configuration is omitted, and the same configuration is shown by the same reference numerals.

As shown in FIGS. 1 to 6, the manufacturing apparatus 250 may further include a buffer sealing member 253. In detail, the buffer sealing member 253 may be provided in a ring shape with a hollow formed therein, and is preferably formed of an elastic material such as synthetic rubber and natural rubber. Here, the hollow is projected upward from the upper surface of the base plate 251 of a rectangular flat plate shape having a predetermined thickness, but on the cross-sectional profile of the communication guide bar 252 provided with an anti-adhesion coating layer 252a formed of Teflon material on the outer surface. It can be formed to correspond. Through this, the buffer sealing member 253 is provided to surround the outer periphery of the communication guide bar 252.

In detail, the buffer sealing member 253 is seated on the upper surface of the base plate 251 and arranged to surround the lower circumference of the communication guide bar 252.

At this time, the buffer sealing member 253 substantially relieves the impact due to the load of the deck body portion 10 in the process (s20) of the deck body portion 10 is seated on top of the manufacturing apparatus 250 Plays a role. That is, the buffer sealing member 253 is disposed between the lower surface of the deck body portion 10 and the upper surface of the base plate 251 to provide elastic recovery force toward the upper side when the deck body portion 10 falls. You can.

Here, the buffer sealing member 253 is preferably formed with a groove (253a) along the inner periphery. In detail, the slack groove portion 253a is formed to a thickness less than the thickness h4 in the vertical direction of the buffer sealing member 253 and may be continuously formed along the inner periphery of the buffer sealing member 253.

At this time, when the upper portion of the buffer sealing member 253 is pressed by the load of the deck body portion 10, the gap between the inner surfaces facing each other in the vertical direction of the free groove portion 253a is narrowed or compressed to each other, resulting in shrinkage. Elastic restoring force is generated. Through this, the buffer sealing member 253 supports the load when the deck body portion 10 is dropped, thereby preventing wear or damage due to contact or collision with the base plate 251, so durability is further improved. Can be improved. Moreover, the quality of the product can be further improved as the deck body part 10 is prevented from contacting the base plate 251 to minimize wear or damage.

On the other hand, the length (h13) of the communication guide bar 252 is the thickness of the base portion provided in the deck body portion 10 (h1 in FIG. 3), a predetermined height of the side wall portion (h2 in FIG. 3) and the buffer It may be set to correspond to the sum of the thickness (h4) of the sealing member 253. Through this, the communication guide bar 252 can guide the coating thickness of the corrosion-resistant anti-slip flooring material as it is inserted and protruded into the drain hole (11a in FIG. 5A) of the deck body 10.

In addition, the communication guide bar 252 is formed with a diameter corresponding to the diameter of the drain hole (11a in FIG. 5a) and is inserted and protrudes into the drain hole (11a in FIG. 5a). At this time, a predetermined gap may be formed between the outer surface of the communication guide bar 252 and the inner surface of the drain hole (11a in FIG. 5A) due to errors caused by manufacturing or deformation due to impact. Therefore, the corrosion-resistant anti-slip flooring material may flow through the gap in the process (s30) of applying the anti-corrosion anti-slip flooring material to the application space of the deck body portion 10.

At this time, the buffer sealing member 253 is a corrosion-resistant anti-slip flooring material in the process (s30) of applying a corrosion-resistant anti-slip flooring material after the deck body 10 is seated on the base plate 251. It can be prevented from flowing through the drain hole (11a in FIG. 5a). That is, the buffer sealing member 253 is provided to surround the outer surface of the communication guide bar 252, but is disposed under the drainage hole (11a in FIG. 5a) so as to be in close contact with the lower surface of the deck body 10. Accordingly, the gap can be substantially sealed.

Here, the buffer sealing member 253 is contracted to correspond to the outer surface profile of the lower surface of the deck body 10 while the deck body 10 is seated on the base plate 251, and at the same time the upper surface of the deck body 10 is contracted. Since it is in close contact with the lower surface of the body portion 10, the gap can be tightly sealed without a gap.

Through this, the lower surface of the deck body portion 10 and the upper surface of the base plate 251 may be prevented from adhering to each other due to the corrosion-resistant non-slip flooring material. Accordingly, it is not only easy to separate with a small force in the process of separating the deck body portion 10 and the base plate 251, but also removing the hardened corrosion-resistant anti-slip flooring material from the lower surface of the deck body portion 10. Since a separate removal process for the above can be omitted, manufacturing convenience can be further improved. Moreover, the corrosion-resistant anti-slip flooring material is prevented from flowing out of the coating space, so consumption is significantly reduced as consumption is minimized, and thus economic efficiency can be remarkably improved. Of course, in some cases, a cover coating layer formed of a material corresponding to the anti-adhesion coating layer 252a may be provided on the upper surface of the buffer sealing member 253 to prevent adhesion of the corrosion-resistant anti-slip flooring material.
