Abstract

<P>PROBLEM TO BE SOLVED: To provide a scrap tire-regenerated rubber body which is made of scrap tires and fit for application to an anti-slip road surface etc. <P>SOLUTION: The scrap tire-regenerated rubber plate is obtained by annularly separating both side wall portions of a tire from a tread portion and shoulder portions of the tire to form rubber cylindrical body, cutting one portion of the rubber cylindrical body perpendicularly to a circumferential direction, and pressing and flatly spreading the cylindrical body. The part of a wire embedded in the rubber plate is pressed so as to be squeezed out of a carcass layer, and therefore the wire is partly protruded from the carcass layer. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、古タイヤを用いて製造される再生ゴム板に関し、特に、横断歩道等においてスリップ防止路面を形成するのに適した再生ゴム板に関する。   The present invention relates to a recycled rubber plate manufactured using old tires, and more particularly to a recycled rubber plate suitable for forming an anti-slip road surface on a pedestrian crossing or the like.

我が国における自動車の数は年々増えつづけており、それに伴い、自動車の部品の廃棄量も増えつづけている。
自動車の部品の中でも、特にタイヤは交換頻度が高い。しかし、タイヤは、焼却すると大気、土壌及び水を汚染してしまい、しかも悪臭を放つため廃棄処理が難しく、そのため廃棄処理のための費用も高い。
このため、古タイヤが野山に不法投棄されるという問題も生じてきている。不法投棄されたタイヤは、害虫の発生源になるため問題であり、また、不法投棄されたタイヤが原因となり火災が発生する等の深刻な問題も現実に生じている。
出願人は、上記した従来の古タイヤの処理に関する問題点を解消するために、スリップ防止用路盤及びタイヤ切断装置に関する特許出願をしている（特許文献１及び２参照）。 The number of automobiles in Japan continues to increase year by year, and along with this, the amount of automobile parts discarded continues to increase.
Among automotive parts, tires are particularly frequently replaced. However, if the tire is incinerated, it will contaminate the air, soil and water, and it will give off a bad odor, making it difficult to dispose of the tire, and therefore the cost for disposal is high.
For this reason, the problem that old tires are illegally dumped in Noyama has also arisen. An illegally dumped tire is a problem because it becomes a source of pests, and a serious problem such as a fire occurring due to an illegally dumped tire has actually occurred.
The applicant has filed a patent application relating to a slip prevention roadbed and a tire cutting device in order to solve the above-described problems related to the processing of old tires (see Patent Documents 1 and 2).

特開平１０−２９８９０９号公報Japanese Patent Laid-Open No. 10-298909 特願２００４−９２８７２Japanese Patent Application No. 2004-92872

出願人は、上記特許出願後も、古タイヤに関する産業廃棄物問題の解消のために鋭意研究を続け、本願発明を発明するに至った。
本発明は、古タイヤを用いて、スリップ防止路面等に用いるのに適した古タイヤ製再生ゴム体を提供することを目的としている。 The applicant has continued intensive research to solve the industrial waste problem related to old tires even after filing the above patent, and has invented the present invention.
An object of the present invention is to provide a recycled tire body made of old tires suitable for use on an anti-slip road surface or the like using old tires.

上記した目的を達成するために、本発明に係る古タイヤ製再生ゴム板は、タイヤのトレッド部及びショルダー部を残して両側のサイドウォール部を円周状に切り離してゴム円筒体を形成し、前記ゴム円筒体の一箇所を円周方向に対して垂直に切断して平板状に押し広げることによりゴム板を形成し、前記ゴム板の内部に埋め込まれたワイヤの一部をカーカス層から押出すようにプレス加工することにより、カーカス層から部分的にワイヤが突出させて成ることを特徴とする。
前記再生ゴム板は、そのカーカス層を下にして道路のアスファルト層に埋め込まれスリップ防止路面として用いられ得る。 In order to achieve the above-mentioned object, the recycled tire plate made of used tire according to the present invention forms a rubber cylindrical body by separating the side wall portions on both sides circumferentially, leaving the tread portion and the shoulder portion of the tire, A rubber plate is formed by cutting one portion of the rubber cylinder perpendicularly to the circumferential direction and spreading it into a flat plate shape, and a part of the wire embedded in the rubber plate is pushed from the carcass layer. It is characterized in that the wire is partially protruded from the carcass layer by being pressed so as to come out.
The recycled rubber plate can be used as an anti-slip surface by being embedded in an asphalt layer of a road with its carcass layer facing down.

本発明に係る古タイヤ製再生ゴム板は、タイヤのトレッド部及びショルダー部を残して両側のサイドウォール部を円周状に切り離してゴム円筒体を形成し、前記ゴム円筒体の一箇所を円周方向に対して垂直に切断して平板状に押し広げることによりゴム板を形成し、前記ゴム板の内部に埋め込まれたワイヤの一部をカーカス層から押出すようにプレス加工することにより、カーカス層から部分的にワイヤが突出させて成るので、そのカーカス層を下にして道路のアスファルト層に埋め込むと、カーカス層から押し出されたワイヤがくさびとなって、前後左右にずれ動くことのない安定したスリップ防止路面を形成することが可能になる。   The recycled tire plate made of an old tire according to the present invention forms a rubber cylinder by circumferentially separating the side wall portions on both sides, leaving the tread portion and the shoulder portion of the tire. By forming a rubber plate by cutting perpendicularly to the circumferential direction and spreading it into a flat plate shape, by pressing a part of the wire embedded in the rubber plate to extrude from the carcass layer, Since the wire partially protrudes from the carcass layer, if the carcass layer is placed below and embedded in the asphalt layer of the road, the wire pushed out from the carcass layer becomes a wedge and does not move back and forth and from side to side A stable anti-slip road surface can be formed.

以下、添付図面に示した一実施例を参照して本発明に係る古タイヤを用いた再生ゴム板の実施の形態について説明していく。   Hereinafter, an embodiment of a recycled rubber plate using an old tire according to the present invention will be described with reference to an embodiment shown in the accompanying drawings.

トレッド部１は直接路面に接する部分であり、ショルダー部２はタイヤの両肩の部分であり、サイドウォール部３はタイヤの側面部分である。
カーカス層５は、タイヤの骨格を形成するためにゴムで被覆された繊維やスチールでできたコード層である。
トレッドとカーカス層５との間には補強のためにベルト６がタイヤの円周方向に設けられており、このベルト６により、衝撃を緩和し、トレッドに生じた外傷がカーカス層５に及ぶことを防ぐ。このベルト６は、内部に複数のワイヤ７が平行に埋め込まれたゴムシート材料から成る。 First, the tire will be briefly described with reference to FIG. FIG. 1 is a schematic cross-sectional view of a tire showing the structure of the tire. As shown in the drawings, the tire includes a tread portion 1, a shoulder portion 2, a sidewall portion 3, a bead portion 4 and a carcass layer 5.
The tread portion 1 is a portion that directly contacts the road surface, the shoulder portion 2 is a portion of both shoulders of the tire, and the sidewall portion 3 is a side portion of the tire.
The carcass layer 5 is a cord layer made of fiber or steel coated with rubber to form a tire skeleton.
Between the tread and the carcass layer 5, a belt 6 is provided in the circumferential direction of the tire for reinforcement. By this belt 6, the impact is mitigated and trauma generated in the tread reaches the carcass layer 5. prevent. The belt 6 is made of a rubber sheet material in which a plurality of wires 7 are embedded in parallel.
