Description
本考案は、プラスチックを原材料とする防犯砂利に関するものである。 The present invention relates to crime prevention gravel made from plastic as a raw material.
従来の防犯砂利は、ガラス発泡体や無機質材発泡体からなり、構造的に連続気泡を有する物質であったため、複層的に敷設して騒音が発生するも、人が踏むとその荷重に対する強度が低く、容易に破砕されて発泡構造が破壊されるため、破砕された発泡体が積まれた砂利の隙間を埋めることになり、使用を続けると騒音を発生させる機能が低下する課題があった。 Conventional security gravel is made of glass foam or inorganic foam, and is a substance that has open cells structurally. Therefore, even if it is laid in multiple layers and generates noise, it is strong against the load when a person steps on it. Because it is low and easily crushed to destroy the foam structure, it is necessary to fill the gaps in the gravel where the crushed foam is piled up, and there is a problem that the function of generating noise deteriorates if the use is continued. ..
さらに従来のガラス発泡体の防犯砂利や無機質材発泡体の防犯砂利は、連続気泡を有する構造のため比重が水よりも軽い１．０ｇ／ｃｍ3以下の物であり、雨水等天候に影響される屋外で使用されると敷設した防犯砂利が雨水に浸水し水に浮いてしまって流されるという課題があった。 Furthermore, the conventional security gravel of glass foam and the security gravel of inorganic foam have a specific gravity of 1.0 g / cm 3 or less, which is lighter than water due to the structure having open cells, and are affected by the weather such as rainwater. There was a problem that the laid security gravel was flooded with rainwater and floated on the water when used outdoors.
従来の防犯砂利は、ガラス発泡体や無機質材発泡体からなり、構造的に連続気泡を有する物質であったため、砂利を複層的に敷設して騒音が発生するも、人が踏む荷重での強度が低く、人が踏むと容易に破砕されて発泡構造が破壊された。そのため、破砕された発泡体が積まれた砂利の隙間を埋めることになり、使用を続けると騒音を発生させる機能が低下し短期間で敷き直しを要する課題があった。 Conventional security gravel is made of glass foam or inorganic foam, and is a substance that has open cells structurally. Therefore, even if gravel is laid in multiple layers and noise is generated, it is under the load that a person steps on. The strength was low, and when a person stepped on it, it was easily crushed and the foam structure was destroyed. Therefore, the gap between the gravel on which the crushed foam is piled up is filled, and if the use is continued, the function of generating noise deteriorates, and there is a problem that the gravel needs to be relaid in a short period of time.
とりわけ、ガラス発泡剤の防犯砂利は自動車の入る場所での使用はしないように仕様書の指示がなされていた。 In particular, the specifications were instructed not to use the security gravel of the glass foaming agent in the place where the car enters.
また、従来のガラス発泡体や無機質材発泡体の防犯砂利は、連続気泡を有する構造のため雨などの気候条件に長期間さらされると、泥や異物などが発泡した気泡に詰まり、騒音が発生しにくくなった。 In addition, conventional security gravel made of glass foam or inorganic material foam has a structure with open cells, so when exposed to climatic conditions such as rain for a long period of time, mud and foreign matter are clogged with the foamed bubbles and noise is generated. It became difficult to do.
騒音を発生させる機能の低下に加えて、防犯砂利の外観が汚染されるため、邸宅等建物構造物の外構の特性である鑑賞物としての美観を持続する期間を短くする欠点があった。
本考案は、前述の欠点を解決しようとするものである。
In addition to the deterioration of the function of generating noise, the appearance of the security gravel is contaminated, so that there is a drawback that the period of maintaining the aesthetic appearance as an appreciation, which is a characteristic of the exterior of a building structure such as a mansion, is shortened.
The present invention attempts to solve the above-mentioned drawbacks.
本考案は、プラスチックを原材料として金型を用いて射出成形し、表面を鏡面仕上げした２種類以上の石形状の物質を組み合わせて、積み重ねた際に生じる隙間空間を意図的に構成し、それらの石形状の物質上に侵入する歩行者が歩行するに当たり荷重がかかり、石形状の物質同士が滑りあい衝突する事で、騒音を発生させる。従来のガラス発泡体や無機質材発泡体の連続気泡を有する構造体により騒音を発生させる防犯砂利に比較して、物質同士が滑りやすく、また破壊強度の低下を招来することなく騒音を発生させ、機能低下を防ぐ部材により防犯砂利の寿命を長期化させ問題点を解決している。 In the present invention, two or more kinds of stone-shaped substances whose surfaces are mirror-finished by injection molding using plastic as a raw material are combined to intentionally form a gap space generated when they are stacked. A load is applied when a pedestrian who invades the stone-shaped substance walks, and the stone-shaped substances slide and collide with each other, generating noise. Compared to the conventional security gravel that generates noise by a structure having open cells of glass foam or inorganic material foam, substances are slippery and noise is generated without causing a decrease in fracture strength. The problem is solved by prolonging the life of the crime prevention gravel with a member that prevents functional deterioration.
プラスチックの比重を１．０ｇ／ｃｍ3以上にすることにより、屋外で使用する際、雨水に浸水する課題を解決している。 By setting the specific gravity of the plastic to 1.0 g / cm 3 or more, the problem of flooding with rainwater when used outdoors is solved.
騒音を発生させるメカニズムを本考案のようにプラスチック成形物質に変えることにより、従来のガラス発泡体や無機質材発泡体では定期的に交換ないし補充が必要であった不便さを解消し騒音を発生させる建築部材の長寿命化を図るとともに、防犯砂利に求められる外観の汚染を大幅に減少させることができて、外観の形状および美観を長寿命化するのに役立つ。 By changing the mechanism that generates noise to a plastic molding substance as in the present invention, the inconvenience that conventional glass foams and inorganic foams had to be replaced or replenished on a regular basis was eliminated and noise was generated. In addition to extending the life of building materials, it is possible to significantly reduce the appearance contamination required for crime prevention gravel, which helps to extend the life of the appearance shape and aesthetics.
プラスチック射出成形工法により、プラスチック素材の石形状の製造工程で着色剤を練りこむ事ができ、異なる色彩の防犯砂利を敷き詰めることが容易となり、多彩な色の効果により、侵入者を視覚的に威圧して防犯する効果及び観賞用としての役割を果たすことも期待できる。 The plastic injection molding method allows colorants to be kneaded in the stone-shaped manufacturing process of plastic materials, making it easy to spread security gravel of different colors, and the effects of various colors visually intimidate intruders. It can also be expected to have a crime-preventing effect and play a role as an ornamental item.
表面を鏡面仕上げしにしたプラスチックを原材料とする石形状の物質にして異なる２種類以上の物質を積み重ねて隙間空間を意図的に構成する。石形状のプラスチック製砂利は表面を鏡面にして滑り性を上げており、単一の石形状のみを重ねた場合は、隙間空間が狭くなるのに比べて、滑り合い、衝突をする機会を増大させ、これにより大きな騒音を発生させる。 A stone-shaped substance whose surface is mirror-finished is used as a raw material, and two or more different substances are stacked to intentionally form a gap space. The stone-shaped plastic gravel has a mirror surface to improve slipperiness, and when only a single stone shape is stacked, the chances of slipping and colliding are increased compared to the narrowing of the gap space. This causes a loud noise.
