Description

[Detailed description of the invention] This invention mainly relates to a legal equipment block that uses old rubber belts from old automobile tires as a resource.

In recent years, for the purpose of reusing industrial waste, old tires and old rubber belts have been cut or crushed into predetermined sizes and used as store paving materials.

Old tires are inherently round, and flooring or paving materials require flatness. It is necessary to mold the material by either crushing it finely and molding it into a plate shape using a binder.

This invention relates to the former.

Legal blocks using old tires that are already on the market are
The square thin rods are simply arranged and attached to the reinforcing cloth lining.

Therefore, if you walk on this with high heel shoes or spiked shoes, the heels and spikes may get caught between the square bars, making it difficult to walk. A strong twist occurs in a part of the square thin rod, and the load concentrates on the part where it is bonded to the reinforcing fabric.
It has the disadvantage of peeling or breaking, so it is not very popular.

This invention improves the drawbacks of such known blocks.

In this device, square thin rods made of synthetic rubber are arranged in contact with each other on the upper surface of a base layer made of a polyurethane layer, and reinforcing fibers embedded therein are exposed on the surface of each square thin rod. This is a rigid mounting block characterized in that the square thin rods and the contact surfaces of the square thin rods are integrally bonded by the polyurethane.

This invention will be explained with reference to the illustrated representative embodiment.

In the figure, reference numeral 10 denotes a paving block, which is usually formed to have a side of 30 cm, but is not limited to this size.

Reference numeral 11 is a thin rectangular rod made by cutting an old tire into thin pieces.The shape of the end face is a rectangle or square with a side of about 10 to 15 mm, and the surface is a reinforcing cloth that was buried as reinforcement when used as a tire. A portion of the fibers 12 are exposed, and when the narrow square rods 11 are spread all over, it looks like a coarse carpet.

These narrow square rods 11 are arranged next to each other in contact with each other on a base layer 13 of polyurethane resin, and are hardened together as shown in FIG. It is formed into a single paving block.

That is, the base layer 13, the group of thin square rods 11 thereon, and the side surfaces of the thin square rods 11 are bonded together by polyurethane resin.

In the base layer 13 of the above-mentioned polyurethane resin, there is usually a reinforcing fabric 14 made of a fine mesh made of chemical fibers such as polyethylene, nylon, vinyl chloride, glass wool, or other vegetable fibers, or a coarse woven or knitted fabric. It is buried.

Even if this reinforcing cloth 14 is located at the interface between the base layer 13 and the rectangular thin rod, or even if it is located at the bottom surface of the base layer 13, the invention is the same, and even if there is no reinforcing cloth 14, this invention is the same. It's the same.

In the above-described embodiment, the 11 groups of square thin rods are cut from old tires, but they may also be synthetic rubber square thin rods molded for use in paving materials, or old rubber belts used for power transmission. Even if a cut piece is used, the invention is the same.

To give an example of a method for forming this block, thin square rods 11 are arranged side by side in contact with each other with their back sides facing up, and a room-temperature curing polyurethane resin is applied on top of the thin square rods 11. The remaining particles flow between the adjacent phase contact surfaces and form a layer on the upper surface, which is then solidified to obtain a product.

When molding something using the reinforcing cloth 14, before application,
During or immediately after, the reinforcing cloth 14 is applied to the back surface of the group of narrow square rods 11 to integrate it with the base layer 13.

In this invention with such a structure, the base layer 13, each thin square rod 11, and the side surfaces of the thin square rods 11 are integrally bonded with polyurethane resin, so that the heel of a biheel or spikes can be placed between the thin square rods 11. The spikes of the shoes do not engage with each other and do not directly touch the base layer 13, resulting in a durable product.

In particular, the paving blocks of this invention are suitable for golf clubhouse lobbies where people enter and exit with spiked shoes, waiting rooms of grand stadiums, long sides of ice skating rinks, other outdoor walkways, and indoor store paving materials.

The thin rectangular rods used in this invention do not all have to have the same size, and two or more types may be combined and bonded.

In addition, a fabric in which the reinforcing fabric 14 is integrated with the base layer 13 is even stronger, and can withstand long-term use even when walking and running with considerable intensity, and is suitable for paving outdoor or indoor jogging courses. Suitable.

There are no particular limitations on the material for the reinforcing cloth 14, but if it is used outdoors or in a place where there is a lot of water due to spraying, etc., non-water-absorbent materials such as polyvinyl chloride or nylon may be used. , one with strong water resistance and abrasion resistance is better.

In addition, the block surface of this device consists of individual thin square rods 11.
Since a part of the reinforcing fabric fibers 12 buried inside are exposed, when the blocks of this invention are laid out, it looks like a woven carpet, which is beautiful and has an anti-slip effect. .
