Description

Stone block for slip prevention {Stone for sliding prevention}

The present invention relates to a stone block such as a sidewalk block or a boundary stone, and more particularly, having irregular irregularities on the upper surface of a boundary stone or marble stairs or a sidewalk block that is constructed in India. The present invention relates to a non-slip stone block that can be manufactured in various colors while forming a non-slip layer, while preventing a crack and damage of the stone block while providing a cushioning force and a pedestrian.

As shown in Figs. 1 and 2, generally, a stone block 10, such as a sidewalk block or a marble staircase (not shown) boundary stone 11 or the like, borders the center of a roadway or the sidewalk and the driveway, or the floor and marble of the sidewalk. Constructed on the staircase to provide convenience for pedestrians walking to protect the vehicle and pedestrians safely, it is made of granite stone, concrete or marble.

The boundary stone 11 of the stone block 10 is formed as a unit object at the end of the sidewalk, that is, the sidewalk and the driveway meet to distinguish the sidewalk and the roadway, and is constructed to be interconnected with the top surface having a smooth surface. In this case, the boundary stone 11 is formed in a process having a higher side than the roadway in the process of construction is constructed in a shape having a certain height difference in the vertical direction from the roadway to naturally create a jaw to distinguish the sidewalk and the roadway.

However, since the upper surface of the boundary stone 11 is smoothly formed and protrudes from the roadway, the boundary stone 11 is installed in a platform of public transportation where many pedestrians are crowded. 11) There is a great risk of a safety accident that slips down.

In particular, when the upper surface of the boundary stone (11) is frozen or wet by snow or rain, relatively weak elderly, children, and even the general public may slip from the boundary stone (11) and fall into the driveway, resulting in bruises or fractures. Frequent accidents occur frequently, and in severe cases, it can lead to serious situations in which traffic accidents occur while sliding from the boundary stone.

In order to solve the above problem, as shown in FIG. A plurality of grooves 14 are formed on the upper surface of the boundary stone 11 formed as a unit object in the longitudinal direction of the boundary stone 11 through separate processing, so that a part of the sole surface of the pedestrian's shoes is pushed into the groove 14. A boundary stone 11 has been developed in which a slip is prevented by being caught.

However, in the conventional non-slip boundary stone 11 as the groove 14 formed on the upper surface of the boundary stone 11 is formed in the intaglio and the gap is also tightly arranged, the sole bottom surface of the pedestrian is the groove (14). As it cannot be pushed into the heel, the friction between the sole and the upper surface of the shoe is greatly reduced, which still does not solve the anti-slip problem.

This problem is similarly shown in the case of the marble stairway or the sidewalk block 12 as well as the boundary stone 11.

In the conventional boundary stone or sidewalk blocks as described above, the upper surface is smoothly formed, so that the upper surface is easily frozen or wetted by snow or rain, and the frictional force between the sole surface and the upper surface of the pedestrian falls, causing slippage. There is a problem that causes human accidents.

On the other hand, even when a separate non-slip groove is machined on the upper surface of the boundary stone, the shoe sole surface is not caught by the groove while the shoe sole surface is not pushed into the groove, thereby reducing the friction between the sole and the upper surface of the shoe. There is a problem that occurs.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an anti-slip stone block to prevent slipping by forming irregular irregularities on the upper surface of the stone block.

In order to achieve the above object, the present invention is a block body made of stone; And it is made of methyl methacrylate resin and stone powder or fine silica, rubber chips, hardeners are mixed, and comprises a non-slip agent applied to the upper surface of the block body to form irregular irregularities on the block body An anti-slip stone block is provided.

In this case, the anti-slip agent preferably has a composition ratio of 15 to 20% by weight of methyl methacrylate resin, 58 to 66% by weight of fine or fine silica sand, 16 to 18% by weight of rubber chips, and 3 to 4% by weight of a curing agent. .

The block body is preferably a sidewalk block or a sidewalk and a pedestrian step or driveway.

The sidewalk block, the boundary stone and the staircase may be made of marble.

According to the non-slip stone block of the present invention configured as described above, by forming a non-slip layer having irregular irregularities on the upper surface of the boundary stone or marble stairs, the sidewalk block, to prevent pedestrians from inadvertently slipping when walking To alleviate the shock transmitted to the pedestrian by the cushioning force of the anti-slip agent, to reduce fatigue, there is an effect that can reduce the minimum injury when the pedestrian falls.

In addition, a separate molding process is not required to have a groove on the upper surface, and there is an effect of cost reduction along with an increase in labor cost according to the molding process.

On the other hand, when the anti-slip agent is formed on the upper surface of the marble stepped jaw, the same effect as that described above can be expected.

And, since the non-slip is applied to the upper surface to prevent cracking and breakage of the stone block, the coating process of the anti-slip agent has the advantage that can be produced in a variety of colors as the process proceeds after the stone block is completed.

While the invention has been shown and described with respect to specific embodiments thereof, it will be understood that the invention can be variously modified and modified without departing from the spirit or scope of the invention as set forth in the following claims. It should be included in the scope of the invention.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

DETAILED DESCRIPTION Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Like reference numerals refer to like elements, and only different parts will be mainly described so as not to overlap for clarity.

FIG. 4 is a state diagram in which a non-slip stone block according to the present invention is constructed separately from a sidewalk and a driveway, and FIG. 5 is a sectional view of the main part of FIG. 4.

As shown in Figure 4 and 5, the non-slip stone block of the present invention, the block body 100, and the anti-slip agent 120 is applied to the upper surface of the block body 100.

In this case, the anti-slip agent 120 is composed of methyl methacrylate resin, stone powder or fine silica, rubber chip 122, the curing agent. In addition, the block body 100 is preferably a sidewalk block 130 or boundary stone (110).

The upper surface of the block body 100 is coated with a non-slip agent 120 to prevent the pedestrian's slip.

The anti-slip agent 120 is 15 to 20% by weight of methyl methacrylate (Methyl methacrylate) resin, 58 to 66% by weight of fine powder or fine silica, and 16 to 18% by weight of rubber chip 122 having elasticity 3 4 wt% is added to form the mixture by high speed mixing.

The methyl methacrylate resin in the composition of the anti-slip agent 120 is in a coated state, there is no change in physical properties due to changes in ambient temperature, that is, high temperature and low temperature, and does not become discolored and discolored by sunlight and various other ultraviolet rays, Penetrated between the micropores of the block body 100 made of stone exhibits a high adhesion.

The methyl methacrylate resin is suitable to have a composition ratio of 15 to 20% by weight. When the ratio of methyl methacrylate is less than 15% by weight, the bond strength decreases, and thus the permeability is significantly reduced. When the ratio of methyl methacrylate is more than 20% by weight, the change in physical properties and discoloration and Discoloration and permeability As the concentration of the methyl methacrylate resin is diluted, the rubber chip 122, which is the composition of the anti-slip agent 120, sinks, so that the uneven surface is not formed.

In the composition of the anti-slip agent 120, stone powder or fine silica is made to have a proper cohesive force of the composition to be mixed, thereby maintaining a stable state until the applied non-slip agent 120 is cured.

Stone powder or fine silica is preferably 58 to 66% by weight of the composition ratio. this is If stone powder or fine silica is less than 58% by weight It is difficult not only to maintain a stable state during hardening of the anti-slip agent 120, but also difficult to realize the shape of the uneven surface, and when the ratio of stone powder or fine silica exceeds 66% by weight, the uneven surface formed causes friction with the pedestrian. The friction makes it difficult to maintain the shape of the uneven surface. That is, the problem that the uneven surface is broken.

The rubber chip 122 of the composition of the anti-slip agent 120 has excellent durability, such as impact resistance and wear resistance, excellent water permeability, and does not generate dust and dust, and thus has hygienic advantages. The rubber chip 122 is preferably to have a composition ratio of 16 to 18% by weight. this is, When the ratio of the rubber chip 122 is less than 16%, the elastic force of the anti-slip agent 120 is lowered, and when the ratio of the rubber chip 122 is more than 18%, the density of the rubber chip 122 is properly increased. After curing, the rubber chip 122 may be separated from the slipper 120 without curing.

The hardener in the composition of the anti-slip agent 120 is a material added to increase the hardness or to promote hardening, and the hardener is preferably to have a composition ratio of 3 to 4% by weight.

When the ratio of the curing agent is less than 3%, the rate at which the anti-slip agent 120 is cured becomes long, and when the ratio of the curing agent is more than 4%, the rate of curing is too fast, making it difficult to secure sufficient working time. In addition, there is a problem that cracks occur in the slipper 120 due to premature curing.

The anti-slip agent 120 made by the composition as described above is applied to the upper surface of the block body 100, and after a predetermined time is cured and adhered in a solid state while maintaining airtightness to the upper surface of the block body 100. . This is because the metal methacrylate resin in the composition of the anti-slip agent 120 is cured while penetrating between the micropores formed on the upper surface of the block body (100).

In addition, the block body 100 is prevented from cracking and breakage because the upper surface is protected from external pressure by the slipper 120 is applied to the upper surface.

The anti-slip agent 120 adhered to the upper surface of the block body 100 includes a rubber chip 122, and the rubber chip 122 has a different height and is irregularly distributed to protrude from the coated surface.

The rubber chip 122 is made by crushing waste tires or waste synthetic rubber, and has elasticity to the non-slip agent 120 as it is mixed with other compositions that are put into the non-slip agent 120 while having a certain elastic force. Done.

According to the present invention, the rubber chip 122 protrudes to the upper portion of the applied slipper 120 to form an irregular uneven surface. Therefore, the slipper 120 applied to the shoe sole of the pedestrian is sufficiently in contact with each other during the walk, and in this process, the rubber chip 122 is elastically deformed while being pressed on the sole of the shoe on which the weight of the pedestrian is loaded. At this time, the rubber chip 122 is in close contact with the shoe sole surface in a state having a different height, the contact with the shoe sole surface occurs at various heights and positions.

Accordingly, the rubber chip 122 greatly increases the frictional force while contacting at various positions and various heights of the shoe sole surface, thereby preventing slippage of the shoe.

On the other hand, when the slipper 120 is applied to the sidewalk block 130 can also expect the effect described above.

In addition, the anti-slip agent 120 is also applicable to the marble stepped jaw having an upper surface. In this case, if the uneven surface is formed on the front upper surface of the marble stepped jaw, the above-described effect can be expected.

In addition, when a pigment of a suitable color is added to the non-slip agent 120 applied to the block body 100, the color may be very easily given to the sidewalk block or the boundary stone to match the surrounding environment.
