　信号炎管は、高速道路等において事故等が発生した場合、火薬の燃焼により発する高光度の炎によって道路作業員が後続車両に事故が発生していることを知らせるために用いられている。かかる信号炎管は、その本体に設けられた発火薬を摺付薬紙により摩擦、着火して火炎や煙を発生させた後、路面上に置いて使用される。 The signal flame tube is used by road workers to notify the following vehicle that an accident has occurred due to a high-intensity flame generated by the burning of explosives when an accident or the like occurs on an expressway or the like. Such a signal flame tube is used after being rubbed and ignited with an igniting agent provided in the main body thereof to generate a flame or smoke by rubbing and igniting it, and then placed on the road surface.

　しかしながら、信号炎管から発生する火炎や燃焼残渣は、最高温度が千数百度に達し、路面上に横に置いた状態で燃焼させると、残渣に接触した部分のアスファルトが焼損し、路面に穴あき状態を発生させる。そして、この状態で路面を放置すると、走行車両のタイヤによる衝撃や風雨等による風化作用により、時間経過とともに穴が大きくなるため、穴埋め等により補修しなければならず、補修費用がかかるという課題を有していた。 However, the flame and combustion residue generated from the signal flame tube reach a maximum temperature of several hundreds of degrees, and when burned while placed on the road surface, the asphalt in contact with the residue burns out, and a hole is formed in the road surface. Generate an open state. If the road surface is left unattended in this state, the hole becomes larger over time due to the weathering effect of the tires of the traveling vehicle and wind and rain, etc. Had.

　上記の課題を解決するために、特許文献１ないし４には、燃焼残渣と路面との接触を阻止するため、断熱層を備えた板状の路面損傷防止体に信号炎管を取り付けたものが開示されている。 In order to solve the above problems, Patent Documents 1 to 4 include a plate-like road surface damage prevention body provided with a heat insulation layer and a signal flame tube attached to prevent contact between the combustion residue and the road surface. It is disclosed.

　しかしながら、これらのものは、板状の損傷防止体に信号炎管を取り付けるものであるため、保管時には嵩張り、またその携帯性の点からも問題があったため、とりわけ一度に５本～１０本程度の信号炎管を同時に扱う必要がある道路作業には不向きであった。 However, since these devices attach a signal flame tube to a plate-shaped damage prevention body, they are bulky at the time of storage and have problems in terms of portability. It was unsuitable for road work that needed to handle a certain number of signal flame tubes at the same time.

　また、これらの損傷防止体は、着火前にあらかじめ取り付けておくものや着火後に取り付けるものがあるが、いずれの場合も使用手順が多くなり、煩雑であった。 In addition, these damage prevention bodies include those that are attached in advance before ignition and those that are attached after ignition. In either case, the procedure for use is increased and complicated.

　さらに、これらの損傷防止体を使用した場合、信号炎管本体以外の燃焼残渣が多くなり、回収作業にも時間がかかるという問題を有していた。 Furthermore, when these damage prevention bodies are used, there is a problem that combustion residues other than the signal flame tube main body increase, and the recovery work takes time.

The signal flame tube used in the present invention may be a general cylindrical one. Further, in this embodiment, in order to prevent the signal flame tube placed on the road surface from rolling, a rolling prevention member 4 formed in a substantially U shape is externally mounted on the outer peripheral surface 11 of the signal flame tube body 1. However, the rolling prevention means is not limited to this, and other rolling prevention members may be used.

　図に示すように、円筒状の信号炎管本体１の外周面１１には、耐火塗料層３が設けられている。耐火塗料層３は、少なくとも、使用時に路面と接する側の外周面１１に形成されている。なお、一般的な信号炎管において、使用時に路面と接する側は特に決まってはいないため、耐火塗料層３は信号炎管本体１の任意の外周面１１に形成すればよく、使用時に該耐火塗料層３が路面側になるように設置すればよい。 As shown in the figure, a fire-resistant paint layer 3 is provided on the outer peripheral surface 11 of the cylindrical signal flame tube main body 1. The fire-resistant paint layer 3 is formed at least on the outer peripheral surface 11 on the side in contact with the road surface during use.

Yes. More specifically, the fireproof paint layer 3 is formed on the outer peripheral surface 11 of the signal flame tube main body 1 so as to extend along the axial direction thereof, but is completely formed to the front and rear ends of the signal flame tube main body 1. As shown in the figure, the front end side and the rear end side may leave some portions where the fireproof coating layer 3 is not formed.

　図２（ａ）は、本発明の信号炎管を路面に置いた状態を模式的に表した図である。なお、本図では、蓋体２や転がり防止部材４などの説明に不要な部材の図は省略する。図に示すように、耐火塗料層３は設置時に路面と接する部分１２から信号炎管本体１の外周面１１の任意の範囲にわたって形成されている。具体的には、少なくとも燃焼時に路面との接触を防ぐとともに、発炎の視認性を損なわない範囲で形成すればよく、路面と接する部分１２を中心に信号炎管本体１の外周総面積の１０～５０％の範囲で形成することが好ましく、３０～４０％の範囲で形成することがより好ましい。 FIG. 2 (a) is a diagram schematically showing a state in which the signal flame tube of the present invention is placed on the road surface. In addition, in this figure, the figure of the member unnecessary for description, such as the cover body 2 and the rolling prevention member 4, is abbreviate | omitted. As shown in the figure, the fire-resistant paint layer 3 is formed over an arbitrary range from the portion 12 in contact with the road surface during installation to the outer peripheral surface 11 of the signal flame tube body 1. Specifically, it should be formed within a range that prevents at least the contact with the road surface at the time of combustion and does not impair the visibility of the flame, and the outer peripheral total area 10 of the signal flame tube body 1 centering on the portion 12 in contact with the road surface. It is preferably formed in the range of ˜50%, more preferably in the range of 30-40%.

　図２（ｂ）は、本発明の信号炎管の燃焼時の状態を模式的に表した図である。図に示すように、信号炎管本体１は燃焼により溶融した残渣１３となり、また、耐火塗料層３は燃焼熱により発泡して路面損傷防止層３１となる。かかる路面損傷防止層３１は、熱により炭化又は灰化した断面略半月状の壁となり、かかる略半月状の路面損傷防止層３１が受け皿となり、残渣１３が路面上に漏出することを防ぐことができる。なお、燃焼時の火炎はその大部分が略半月状の路面損傷防止層３１よりも上に立ち昇るため、火炎の視認性が妨げられることはない。 FIG. 2 (b) is a diagram schematically showing the state of the signal flame tube of the present invention during combustion. As shown in the figure, the signal flame tube main body 1 becomes a residue 13 melted by combustion, and the refractory paint layer 3 is foamed by combustion heat to become a road surface damage prevention layer 31. The road surface damage prevention layer 31 becomes a substantially half-moon shaped wall carbonized or ashed by heat, and the substantially half-moon shaped road surface damage prevention layer 31 serves as a tray to prevent the residue 13 from leaking onto the road surface. it can. Note that most of the flame during combustion rises above the substantially half-moon-shaped road surface damage prevention layer 31, so that the visibility of the flame is not hindered.

　本発明において耐火塗料層３を形成する耐火性の塗料は、２５０～３００度程度の燃焼熱によって発泡する樹脂成分を含み、建材などに使用される耐火性塗料を使用することができる。具体的には、ＳＫタイカコート主材ＥＸ、ＳＫ水性タイカコート（いずれもエスケー化研株式会社製、「ＳＫタイカコート」は登録商標）、タイカリット（日本ペイント株式会社製、「タイカリット」は登録商標）、ウェスタ（菊水化学工業株式会社製、「ウェスタ」は登録商標）、ナリファイア・システムS、ナリファイア・ハイブリッドベースコート（いずれもNullifire製、「ＮＵＬＬＩＦＩＲＥ」は登録商標）などが好適に使用できる。 In the present invention, the fire-resistant paint that forms the fire-resistant paint layer 3 includes a resin component that foams by combustion heat of about 250 to 300 degrees, and fire-resistant paint used for building materials and the like can be used. Specifically, SK Tika Coat Main Material EX, SK Waterborne Tika Coat (both manufactured by SK Kaken Co., Ltd., “SK Tika Coat” is a registered trademark), Taikalite (manufactured by Nippon Paint Co., Ltd., “Tykalit” is a registered trademark), Wester (Kikusui Chemical Co., Ltd., “Westa” is a registered trademark), Nullifier System S, Nullifier Hybrid Base Coat (both manufactured by Nullifire, “NULLLIFIRE” is a registered trademark) and the like can be suitably used.

　耐火塗料層３は、発泡時に路面損傷保護機能を有するに十分な厚みに形成すればよく、１００μｍ～２ｍｍの厚みに形成することが好ましい。かかる範囲で耐火塗料層３の厚さを形成することにより、信号炎管を燃焼させた後の残渣を最小限にすることができ、路上にかかる残渣が残存した場合も炭化、灰化して車両の走行や作業員の歩行を妨げない。さらに、耐火塗料層３を形成した信号炎管は元の形状・外寸等の大きな変更を伴わないため、既成の転がり防止部材の装着や、着火機構に不具合が出るおそれもない。 The fire-resistant paint layer 3 may be formed to a thickness sufficient to have a road surface damage protection function during foaming, and is preferably formed to a thickness of 100 μm to 2 mm. By forming the thickness of the refractory paint layer 3 in such a range, the residue after burning the signal flame tube can be minimized, and even when the residue on the road remains, it is carbonized and ashed to form a vehicle. It will not interfere with the running or walking of workers. Further, since the signal flame tube in which the fire-resistant paint layer 3 is formed is not accompanied by a large change in the original shape, outer dimensions, etc., there is no possibility that the existing rolling prevention member is attached or the ignition mechanism is not defective.

　耐火塗料層３は信号炎管本体１の外周面１１に耐火性の塗料を直接塗布して形成してもよいが、シート状の基材の一面に塗布して形成し、該基材を外周面１１に貼着して形成してもよい。このように、耐火塗料層３をシート状基材とすることで、耐火性塗料を信号炎管本体１に直接塗布した場合と比べて乾燥時間を短縮できる。また、かかるシート状基材を、基材、耐火性塗料、接着剤、離型紙の４層構造にあらかじめ形成しておくことにより、外周面１１に貼着する作業をより簡略化でき、好ましい。 The fire-resistant paint layer 3 may be formed by directly applying a fire-resistant paint to the outer peripheral surface 11 of the signal flame tube main body 1, but is formed by applying it to one surface of a sheet-like base material. It may be formed by sticking to the surface 11. Thus, by using the fire-resistant paint layer 3 as a sheet-like base material, the drying time can be shortened as compared with the case where the fire-resistant paint is directly applied to the signal flame tube body 1. In addition, by forming such a sheet-like base material in advance in a four-layer structure of a base material, a fire-resistant paint, an adhesive, and a release paper, the operation of sticking to the outer peripheral surface 11 can be further simplified, which is preferable.
