Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.
FIG.1 and FIG.2 shows an example of the flame generating cylinder which made the signal soot tube holder hold the signal soot tube.

  The flame tube 100 includes a signal soot tube holder 200, a signal soot tube 300 held thereon, and a pair of belt-like adhesive tapes 400 that fix the signal soot tube 300 to the signal soot tube holder 200. . Here, on the surface of the adhesive tape 400, for example, information such as the specification and expiration date of the flame generating cylinder 100 can be attached.

  The signal soot tube holder 200 includes a combustible container 220 having a mounting surface (concave portion) on which at least a combustion site of the signal soot tube 300 is placed, and a liquid that protects an asphalt road surface and the like from the combustion residue of the signal soot tube 300. A non-combustible material 240.

  The combustible container 220 is a paper container made of thick paper such as uncoated paper, and has a channel-shaped (U-shaped) cross section with an open top surface. A container body 224 is included. Here, the channel shape may be such that it can be recognized as a channel shape in appearance. The first container main body 222 and the second container main body 224 are connected to each other in the longitudinal direction through, for example, an adhesive tape so that they can be bent with respect to each other. Note that the first container main body 222 and the second container main body 224 can be formed by appropriately bending one cardboard.

  In addition, a plurality of slits 226 extending from the intermediate portion toward the lower end are formed on both side surfaces of the first container body 222 and the second container body 224, that is, both side walls of the recess forming the channel shape. ing. The length and number of the slits 226 can be determined in consideration of the strength with which the combustible container 220 can hold the signal soot tube 300, for example. Further, the outer surface visually recognized when the combustible container 220 is installed on an asphalt road surface, specifically, at least both side surfaces of the first container body 222 and the second container body 224 and the inner surface of the recess are colored gray. May be. In this way, even if a part of the combustible container 220 remains unburned, since the burnt-out is colored gray, it is difficult to distinguish it from an asphalt road surface and the like, and it can be made inconspicuous.

  A protruding portion 228 that protrudes downward from the outer bottom surface (lower surface) of the first container body 222 is formed at the distal end of the first container body 222, that is, at one end in the longitudinal direction of the combustible container 220. . The protruding portion 228 is made of the same material as the first container body 222 and the second container body 224, and is integrated with the first container body 222 via an adhesive, a double-sided tape, or the like, for example. Note that when the combustible container 220 is formed by appropriately bending a sheet of cardboard, the protruding portion 228 may be formed at the same time.

  The liquid incombustible material 240 is obtained by filling a flammable bag with, for example, a non-flammable or flame-retardant gel substance having low fluidity (high viscosity). Examples of gel-like substances include water-absorbing polymers that absorb water, materials such as inexpensive starch paste, gelling agents such as gelatin, inorganic or organic adhesives, gels used for hairdressing, etc. can do. Therefore, the liquid non-combustible material 240 has a characteristic that the bag easily burns, but the heat resistance performance is exhibited by the contents.

  As shown in FIG. 3, the liquid non-combustible material 240 includes two first non-combustible materials 242 disposed on the upper surface of the concave portion of the combustible container 220 and 5 disposed on the lower surface of the concave portion of the combustible container 220. And a second incombustible material 244.

  The first incombustible material 242 has at least approximately the same width as the concave portion of the combustible container 220 and has a length greater than half of the entire length of the combustible container 220. Therefore, as shown in FIG. 4, the end portions of the first non-combustible material 242 are overlapped to cover the entire upper surface of the concave portion of the combustible container 220.

  In addition, the second non-combustible material 244 has substantially the same width as the concave portion of the combustible container 220 and has a length greater than 1/5 of the total length of the combustible container 220. Therefore, as shown in FIG. 4, the end portions of the second non-combustible material 244 overlap to cover the entire lower surface of the concave portion of the combustible container 220.

  Note that two or more of the first incombustible material 242 and the second incombustible material 244 may be arranged side by side in the width direction of the recess of the combustible container 220. Moreover, the 1st noncombustible material 242 may be 1 or 3 or more, and the 2nd noncombustible material 244 may be two or more. Here, the first incombustible material 242 and the second incombustible material 244 are examples of the first liquid incombustible material and the second liquid incombustible material, respectively.

  Three second non-combustible materials 244 are disposed on the lower surface of the concave portion of the combustible container 220 and two on the lower side thereof. In order to suppress the upper surface of the second non-combustible material 244 positioned below from being welded to the second non-combustible material 244 positioned above when burned, for example, paper 230 such as water-soluble paper. Is pasted. Note that the paper 230 is not limited to a configuration in which the paper 230 is attached to the upper surface of the second non-combustible material 244 positioned below, and it is sufficient that the paper 230 is interposed at least in the overlapping portion of the second non-combustible material 244. Further, the number of second non-combustible materials 244 may be two at the top and three at the bottom.

  The signal soot tube 300 includes a soot tube body 310 filled with explosives and the like, and a cap 320 that covers an ignition part 312 provided at one end of the soot tube body 310 in the longitudinal direction. The soot tube main body 310 has, for example, a cylindrical shape made of a combustible material such as cardboard. On the outer peripheral surface of the cap 320, an ignition part 330 is applied or stuck, which ignites by rubbing the ignition part 312 of the soot tube main body 310. Note that the caps 320 of the signal dredge 300 can be fixed to each other with, for example, an adhesive tape so that the cap 320 is not easily detached from the dredge main body 310 during transportation.

  Then, the signal soot tube 300 is accommodated in the recess of the combustible container 220, and the signal soot tube 300 is fixed with the adhesive tape 400 at two spaced positions of the second container body 224 of the combustible container 220, so that the flame tube 100 is assembled. At this time, in the signal soot tube 300, the tip of the cap 320 is located in the middle portion of the first container body 222 of the combustible container 220, and the soot tube starts from one end of the second container body 224 of the combustible container 220. The base end of the main body 310 is accommodated so as to protrude. That is, the combustible container 220 holds the signal soot tube 300 so that at least the combustion part of the signal soot tube 300 is placed.

Next, the usage method and effects of the flame generating cylinder 100 will be described.
For example, when lane regulation is performed at a construction site on an expressway, a flame tube 100 is arranged on the road surface at an appropriate interval and ignited in order to urge a passing vehicle to change lanes. At this time, as shown in FIG. 5, the operator bends the first container body 222 with respect to the second container body 224 of the combustible container 220 and removes the cap 320 of the signal soot tube 300. When the cap 320 of the signal soot tube 300 is removed, the ignition unit 312 of the soot tube main body 310 is exposed, so that it can be easily ignited by rubbing with the ignition unit 330 of the cap 320. Thereafter, the operator returns the first container body 222 of the combustible container 220 to the original shape, and installs the flame generating cylinder 100 at a predetermined position on the road surface 500 such as an asphalt road surface as shown in FIG.

  In the state where the flame generating cylinder 100 is installed on the road surface 500, since the protrusion 228 is formed on the first container main body 222 of the combustible container 200, the bottom surface of the recess of the combustible container 200 is as shown in FIG. The slope is such that the ignition part 312 of the signal soot tube 300 becomes higher. For this reason, even if the combustion residue which jumped out from the front-end | tip part of the signal soot pipe 300 accumulates in the recessed part of the combustible container 220, it flows into the front-end | tip part of the combustible container 220, and is dripped at the road surface 500. Further, since the ignition portion 312 of the signal soot pipe 300 is inclined so as to be positioned at a high position, the combustion residue from the tip portion is ejected obliquely upward and does not directly hit the road surface 500. Therefore, the road surface 500 can be protected from the combustion residue of the signal soot pipe 300.

  Furthermore, since the liquid non-combustible material 240 is interposed between the signal soot pipe 300 and the road surface 500, even if the soot pipe body 310 and the combustible container 220 burn, the combustion heat is transmitted to the road surface 500. Is suppressed. The liquid incombustible material 240 includes a first incombustible material 242 disposed on the upper surface of the recessed portion of the combustible container 220 and a second incombustible material 244 disposed on the lower surface of the recessed portion of the combustible container 220. Although divided, if the capacity as a whole is ensured, the effect of suppressing the transmission of combustion heat can be obtained. Moreover, since the 1st incombustible material 242 and the 2nd incombustible material 244 have the adjacent edge part overlapped, it can suppress that a combustion heat is transmitted from a clearance gap.

  Since a plurality of slits 226 are formed on both side surfaces of the first container main body 222 and the second container main body 224 of the combustible container 220, the scum can be reduced. At this time, since the first container main body 222 and the second container main body 224 are made of uncoated paper, the first container main body 222 and the second container main body 224 are easy to burn, and the absolute amount of burnout can be reduced. In addition, since at least the inner surface and the outer surface of the concave portions of the first container body 222 and the second container body 224 are colored in gray, even if the scum is scattered on the road surface 500, it should not be noticeable. Can do.

  The first non-combustible material 242 of the liquid non-combustible material 240 directly receives the heat of combustion of the signal soot tube 300, so that it is difficult to leave the residue. On the other hand, since the second non-combustible material 244 receives combustion heat via the first non-combustible material 242, unburned residue tends to occur. At this time, since the second non-combustible material 244 is divided so as to reduce its size, it can be made inconspicuous even if it remains somewhat burned. Further, since the second non-combustible material 244 has a paper 230 such as water-soluble paper interposed at the portion where the end portions overlap each other, it is suppressed that two or more things are integrated when the bag burns. And can reduce the scum. Here, by making the paper 230 water-soluble paper, even if it remains unburned, it will melt and become invisible by hitting it with rain, for example.

  When the flame cylinder 100 using the signal soot tube 300 with a combustion time of 15 minutes was actually burned, combustion residues of the flame cylinder 100 were found on the road surface 500 as shown in FIG. However, the combustion residue is finer. For example, when the vehicle travels on the combustion residue, the combustion residue becomes finer and collects in the side groove due to wind or rain. For this reason, even if the combustion residue of the flame cylinder 100 is not removed, it cannot be seen from the road surface 500. The combustion residue collected in the side groove can be removed by a regular cleaning operation.

  In the signal soot tube holder 200 of the flare tube 100 described above, the recess that accommodates the signal soot tube 300 has a channel shape, but the recess may be applied in various shapes such as an arc shape and a V shape. it can. In short, the signal flame tube holder 200 may have any shape as long as the signal flame tube 300 can be firmly held in its cross section.
