Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to paving materials, and more specifically, to paving materials for the ground and roads such as asphalt tiles, and more particularly to paving materials that can be used as a substitute for flooring materials such as plastic tiles. The present invention relates to bedding materials having elasticity, and in particular to bedding materials made of rubber or synthetic resin materials that are not corrosive and would pose environmental problems if simply discarded.

[Prior Art] Conventionally, for example, roads were laid with asphalt, and in places where the ground was exposed and muddy areas grew during rainy weather, asphalt, stones, bricks, tiles, etc. were laid. ing.

In particular, in various convention facilities, places where muddy areas are a problem, roads, etc., unless necessary,
This is done to avoid damage if the ground is exposed.

The asphalt, stones, bricks, tiles, etc. that are laid on the ground are strong against large loads and impacts, and have excellent durability.

However, it is extremely hard and has low vibration absorption properties, which increases the load on pedestrians.Also, in rainy weather, hard and durable materials tend to be more slippery than the ground. Was.

Under these circumstances, it is common practice to crush waste materials such as tires (A) into fine particles, sprinkle the particles on the ground, and heat and compress it to harden it. The construction work had the disadvantage that it was affected by the weather and the construction work itself could not be completed in rainy days.

Therefore, it has become common to mix particulate synthetic resin or rubber material with an adhesive, pressurize and heat it to harden it, and use it as a bedding material.

(Problem to be solved by the invention) However, when the above-mentioned elastic bedding material is used for a long time after being laid, the elastic particles tend to fall off as the surface deteriorates. Therefore, when trying to increase the durability of the elastic material, increasing the adhesive content compared to the elastic material achieves the objective, but the adhesive content increases. Due to the increased height, there was a problem in that the original advantage of elasticity was reduced.

In addition, because the conventional concrete flooring material (31) is molded under pressure, and when trying to increase its strength, it is hardened so that the particles come into close contact with each other, resulting in poor air permeability. Like ~ and Asphal 1-, it becomes hot when exposed to direct sunlight for a long period of time in the summer, and its heat absorption is poorer than that of the ground.

It also had the disadvantage of being exclusionary. The above-mentioned drawbacks are exacerbated, for example, when the content of the adhesive is increased in order to improve durability.

In addition, in the case of bedding materials using conventional particulate elastic materials,
As a result of the conflicting functions of strength and elasticity, when manufacturing bedding materials, the scope for adjusting the balance between both functions is extremely narrow, and one is forced to make a clear choice as to which function to place emphasis on. te=3- was there.

The problem of the present invention is to provide a bedding material that has contradictory characteristics with ml durability and elasticity, that is, a bedding material that is durable while maintaining high elasticity, and has good air permeability and drainage. Our goal is to provide the following.

[Means for Solving the Problems] The above-mentioned problems of the present invention are achieved by mixing at least a long elastic material and an adhesive, and compressing and solidifying the long elastic material while keeping its original shape. This problem is solved by a bedding material that is characterized by:

Further, the object ``1'' of the present invention is solved by a bedding material configured such that the size of the elastic material is different on one side and the other side in the thickness direction of the bedding material.

Furthermore, the object of the present invention (1) is solved by a bedding material characterized in that a specific display made of a fluorescent material is formed on at least the surface side.

Moreover, the above-mentioned problems of the present invention are solved by a bedding material characterized by mixing a noncombustible material.

In addition, the object of the present invention is as follows.
-- solved by a bedding material with grooves that can be interconnected with adjacent ones.

[Effect]

By hardening rectangular elastic materials, the materials can intertwine with each other, so in addition to the bonding force of the adhesive, an anchor effect, also known as entanglement force, occurs, increasing the bonding force between the materials, Durability can be dramatically increased. Also, since the shape of the elastic material is long,
Even when compressed and molded under considerable pressure, the materials do not come into close contact with each other, and appropriate gaps can be created between the materials. Therefore, it is possible not only to improve the durability without impairing the original elasticity of the elastic material, but also to provide a bedding material that is extremely excellent in terms of both breathability and drainage performance.

In addition, by making the bedding material so that the size of the elastic material is different on one side and the other side in the thickness direction of the bedding material, for example, by making the front surface thin and the back surface rough, the surface It is possible to separate the functions of the front and back surfaces, so that the sides have the functions of aesthetics, elasticity, and durability, and the back side has the function of increasing drainage and ventilation, so on the surface they are exactly the same. Even though it may seem like a problem, it can be applied to a construction method with separate functions in the case of installation, and it can increase the adaptability of the installation.

Further, by incorporating a fluorescent material into the surface and forming a specific display, such as a destination display or other cautionary display using the fluorescent material, the display effect becomes extremely effective even at night.

In addition, by having grooves on the back side of Mat + 2 that connect with the adjacent ones, these grooves can function as drainage passages, making extremely effective drainage possible. In addition, it is possible to achieve the remarkable effect that there is no need to construct a relatively fine drainage ditch in the base portion on which the bedding material is laid.

(Example) Hereinafter, an example of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to this example.

Fig. 1 is a plan view of the bedding material of this example, and Fig. 2 is a plan view of the bedding material of this example.
3 is a sectional view taken along the line A-A in the figure, and FIG. 3 is a plan view showing the bottom surface of the bedding material shown in FIG. 1.

Not shown in Figure 1, bedding material 1 has linear uneven contour lines 2 and 3.
On the opposite side of the top and bottom in the figure, there is a curved concave and convex contour line 4.
and 5 are located on opposite sides in the left and right directions in the figure. The vertical and horizontal unevenness relationships are exactly opposite, so that when a large number of bedding materials 1 are lined up, they are combined so as not to be misaligned with each other.

The material constituting the bedding material 1 is, for example, an elastic material 6 made of a long rubber material such as a tire, mixed with an adhesive such as urethane resin, and the mixture is packed into a suitable mold. Thereafter, it can be molded into a desired shape by applying appropriate pressure and heating. Note that the elastic material G is hardened while retaining its original shape. Therefore, the elastic materials 6 are firmly solidified so as to intertwine with each other, and an appropriate space is formed between the elastic materials 6, so that this space reduces spatial restrictions when the elastic materials 6 expand and contract. As a result, the original elastic force of the elastic material 6 is brought out and extremely excellent elasticity can be exhibited.

The long length of the elastic material 6 here generally means that the length in the long direction is approximately 2 (hereinafter referred to as "2") compared to the length in the short direction.

Furthermore, grooves 9 as shown in FIGS. 2 and 3 are formed in the bottom surface 8 of the pad A1. This groove No. 9J is formed so as to connect with the groove of another adjacent bedding material 1.
It has the effect of increasing the air permeability and drainage performance of the water.

The pad +A' 10 shown in FIG. 4 has the same shape as that shown in FIGS. 1 to 3, but has a structure in which a particulate material 11 is mixed in in addition to the elastic material 6.

The particle material 11 may be an elastic material or an inelastic material such as gravel. In this way, particle material 11
By mixing it with the long elastic material 6, the particle material 11 enters the space formed by the elastic material 6, so the elastic force can be easily adjusted depending on the use of the material. can.

The size of the particle material 11 is not particularly limited,
It can be determined as appropriate depending on conditions such as the material and the size of the elastic material 6. Furthermore, by using, for example, stone, sand 1, brick powder, shellfish powder, or a fibrous non-combustible material as the particulate material 11, the bedding material 10 can be made difficult to burn.

The bedding material of the present invention can also be constructed as shown in FIG.

The configuration in this case is the size distribution of the diameter, length, etc. of the elongated elastic element tA' 6 (this size distribution is called this because there is variation in size when making the elastic material)
In addition to having a plurality of size distributions, the particle material is also strained so that, for example, the large particle material 21 is located on the bottom side.
It is shaped so that the small particle material 22 and the elastic material 6 are located thereon. Since the bottom side is made of a material with a large size, it is possible to improve air permeability and drainage performance and adjust elasticity without forming the aforementioned grooves.

Furthermore, the surface 7 of the bedding material 20 may be made of, for example, a fluorescent material or a material containing a fluorescent material.
A specific display section 25 such as an arrow display for lil guidance is provided. As a result, an extremely excellent display function can be achieved even in the case of an emergency at night.

The display section 25 may be attached after the support material 20 is molded, but it can also be formed at the same time as the bedding material 20 is molded. Therefore, since the display section 25 can be formed from the elongated elastic material 6, the display section 25 can maintain its display function for a long period of time.

It goes without saying that the present invention is not limited to the embodiments described above, and can be modified as appropriate, for example, in the overall shape, shape and number of grooves, material, size, thickness, etc.

In the above embodiments, a long elastic material having a shape that can be called a hijiki-like shape (the shape of a deertail) was described, but the present invention is not limited to this shape, and the long elastic material has an appropriate width in the short direction. It may also be in the form of a band.

In addition, in the two examples, the size of the particulate material is appropriately adjusted to fit into the intertwining gap between the elongated elastic materials. By setting the amount so that it is contained in a large amount in the direction of the bedding material, it becomes difficult for dust etc. to enter the bedding material, and it can be suitably employed as a part of floor + A and the like.

In addition, in the above embodiment, the front and back sides of the bedding material were used in a predetermined usage pattern, but a configuration in which both the front and back sides can be used,
The structure may be such that the front and back sides are used as appropriate depending on the purpose of use. For example, the front and back surfaces of adjacent bedding materials can be laid upside down alternately, and the planar contour may be configured. You can also do it.

〔Effect of the invention〕

The bedding material of the present invention has a structure in which at least a long elastic material and an adhesive are mixed, and the long elastic material is compressed and solidified while the original shape of the long elastic material is maintained. In this way, by hardening the rectangular elastic materials -1,1--, the materials can be entangled with each other, so it is possible to create an anchor that can be used not only with the bonding force of adhesive but also with the entanglement force. The effect occurs, increasing the bonding strength between materials and dramatically increasing durability. Furthermore, since the elastic material is elongated, the materials do not come into close contact with each other even when compression molded under considerable pressure, and an appropriate gap can be created between the materials. therefore,
Not only can the durability be improved without impairing the original elasticity of the elastic material, but also a bedding material that is extremely excellent in terms of breathability and drainage performance can be provided.

In addition, by making the bedding material so that the size of the elastic material is different on one side and the other side in the thickness direction of the bedding material, for example, by making the front surface thin and the back surface rough, the surface It is possible to separate the functions of the front and back surfaces, so that the front side has the functions of aesthetics, elasticity, and durability, and the back side has the function of increasing drainage and ventilation, so the two sides are exactly the same. Although it may seem simple, it can be applied to functionally separated construction methods, increasing its adaptability to installation.

Furthermore, by incorporating a fluorescent material into the surface and forming a specific display, such as a destination display, using the fluorescent material, the display effect becomes extremely effective even at night.

In addition, by having grooves on the back side of the bedding that connect the adjacent ones, the grooves can function as drainage passages, making extremely effective drainage possible. Moreover, it is possible to achieve the remarkable effect that it is not necessary to provide a relatively fine drainage groove in the base portion on which the bedding material is laid.
