BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip device for preventing a surface of a grating from being used as a gutter, a tread for a stair, or a floor plate.

[0002]

[Problem to be solved by the invention] Kitchens such as restaurants,
Grating provided on the floor of a place where oil is generated, such as a factory where a machine tool is attached, is easy to deposit oil on the surface due to oil mixed into the influent water, so that the surface becomes slippery, It is dangerous because the worker may overturn. Further, the stair treads need to be provided with a non-slip for safety maintenance.

Conventionally, a non-slip sheet made of a synthetic resin having a roughened surface is attached to a part of the grating to prevent the slip. By the way, with such means, in the case of the grating used as a groove cover, the grating is covered, and a part of the grating becomes impervious to water, and the grating function cannot be sufficiently performed. The surrounding atmosphere is always in a wet state, and the adhered side is made of metal, so that it is easily peeled off and needs to be replaced each time. As another conventional means, there is a method in which a metal anti-slip member is welded to the upper surface of the grating. However, such a means requires that the surface of the grating be flush with the surface of the grating. In addition to the above, there is a drawback that mounting work is troublesome, and when used as a groove cover, the degree of opening of the grating is reduced as described above. Further, both of the above-mentioned conventional examples have a disadvantage that the anti-slip effect is limited to a portion where the anti-slip member is provided.

On the other hand, as a configuration for eliminating the above-mentioned disadvantages,
A number of knurled knurls formed on the upper surface of a long base material to prevent them from slipping have also been proposed. However, in such a configuration, there is a problem that a mold is complicated and a material unit price is increased. An object of the present invention is to provide a grating anti-slip device that does not have the above-mentioned disadvantages.

SUMMARY OF THE INVENTION According to the present invention, a grating, which is assembled by holding a number of long substrates in alignment with a certain gap therebetween, is provided on the upper surface of the long substrates.
Forming irregularities of several microns by blasting,
Plasma spraying using a spray material made of ceramic material
Covering the wear-resistant thermal spray coating layer by applying
Thus, a rough surface is formed on the upper surface . Examples of the wear-resistant ceramic material include alumina (Al ₂ O ₃ ), titania (TiO ₂ ), a mixture of alumina and titania, titanium dioxide, chromium oxide, zircon, tungsten carbide, titanium carbide, chromium carbide,
Molybdenum or the like is applied. These are all materials that can be coated by plasma spraying.

[0006]

In order to form a thermal spray coating layer, first, the upper surface of the long base material is formed with irregularities of several microns by sandblasting, and then a known thermal spraying material made of a ceramic material is used. This is done by applying a thermal spray technique. Thus, the thermal spray material is bonded and joined by the uneven surface, and a rough surface is formed on the surface.

[0007] The rough surface prevents slippage, and the abrasion resistance of the rough surface prevents the rough surface from being worn even if the upper surface of the grating is constantly subjected to friction due to the passage of a vehicle or the like. The effect will be maintained continuously.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a long base material 2 made of stainless steel according to the present invention, which has a substantially T-shaped cross section, and a grating 1 is assembled by combining these.

The structure of the grating 1 will be described.
As shown in FIGS. 2 to 4, a large number of connection rods 7 are inserted at regular intervals into insertion circular holes 6 drilled at appropriate positions of the long base material 2.
Spacers 8 are provided between the long base materials 2 so as to be fitted to the connecting rods 7 so that a plurality of long base materials 2 are connected in parallel at a constant interval. As shown in FIG. 4, side end pipes 10 each having a flat surface 11 on its outer surface are inserted into both ends of the linked body of the long base material 2, and have a U-shaped cross section having a groove 14 on its outer surface. The side plate 13 is the flat surface 11
Through holes 15 formed in the groove 14 at regular intervals.
The rivet 16 into the fitting hole 12 formed in the flat surface 11
Are fitted to connect the side end pipe 10 and the side plate 13. As shown in FIG. 3, a side plate 18 having the same shape as the side plate 13 abuts on the front and rear ends of the connecting body, and screw holes 2 formed at both ends of the connecting rod 7 through the through holes 20 of the grooves 19.
Screws 22 are respectively screwed onto the 1 to form a rectangular grating 1.

In such a configuration, a wear-resistant sprayed coating layer 3 made of a ceramic material is formed on the upper surface of each long base material 2. The means for forming the thermal spray coating layer 3 can be applied using a known thermal spraying technique such as plasma spraying.

That is, as a thermal spray material made of a ceramic material for forming the thermal spray coating layer 3, alumina (Al ₂ O ₃ ), titania (TiO ₂ ), a mixture of alumina and titania, titanium dioxide, chromium oxide, Zircon, tungsten carbide, titanium carbide, chromium carbide, molybdenum and the like are applied. The thermal spray coating layer 3 is formed by previously forming unevenness of several microns on the upper surface of the long base material 2 by sandblasting, and performing plasma spraying on the unevenness using the thermal spray material.

Then, the thermal spray material is bonded and joined by the uneven surface, and a rough surface is formed on the surface. Thus, the rough surface prevents slipping, and due to its abrasion resistance, even if friction due to passage of a vehicle or the like is constantly applied to the upper surface of the grating 1, the rough surface is not worn out. The anti-slip effect will be maintained continuously.

The thermal spray coating layer 3 may be formed on the upper surface of the long base material 2 before the grating 1 is assembled.
Further, after the grating 1 is assembled, it can be formed on the upper surface of each long base material 2.

Since the grating 1 has the above-described structure, a rough surface is formed by the thermal spray coating layer 3 of the long base material 2. Will be applied.

[0015]

As has been made clear from the above description, the present invention provides a grating 1 which is assembled by holding a number of long base materials 2 at a certain gap and holding the same. On the top surface, sandblasting
After the unevenness of the cron is formed, the abrasion-resistant sprayed coating layer 3 made of a ceramic material is formed to form a roughened surface. Thus, the upper surface of the grating 1 is formed on the upper surface of the grating 1 by friction accompanying passage of a vehicle or the like. Non-slip surfaces that are not worn out and do not cover the anti-slip material etc. from the upper surface of the grating 1 so that even when the grating 1 is used as a groove cover, the anti-slipping operation is performed without impairing its water permeability. In addition, since a mold or the like is not used, there are excellent effects such as low production cost.
