Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fireproof safe car capable of withstanding a fire caused by an accident, a robbery, or the like.

[Prior Art] A safe car known as a cash transport vehicle for transporting cash, securities, and the like may be caught in a fire due to an accident, a robbery, or the like. In this case, there has been a demand to make a fireproof safe car with fire resistance so that the cash and securities to be transported are not burned out.

〔Problems to be solved〕

Many of the conventional safe cars are equipped with a fixed safe in the vehicle, and are heavy and not suitable for in-vehicle use. This is because the stationary safe is intentionally heavy in case of theft or the like. If the safe is heavy, the vehicle weight of the safe is increased, and the maximum load capacity (allowable load capacity) is reduced accordingly. Therefore, when trying to increase the load weight, it is necessary to reduce the safe volume, and it is not possible to secure an allowable load weight commensurate with the safe capacity.

Further, in order to provide fire resistance, only the fixed-type safe was diverted, and therefore, there was no one that had the capability of withstanding a vehicle fire, particularly a fire in a tunnel.

An object of the present invention is to solve the above problems and provide a fireproof safe car having a large and lightweight body with a built-in safe, which has a fireproof performance capable of withstanding a vehicle fire.

[Means for solving problems]

In order to achieve the above object, the fireproof safe car according to the present invention is a fireproof safe car having a built-in safe body,
The cross-sectional structure of all walls including the floor and ceiling of the safe-incorporating body has a metal inner plate, a ceramic fiber heat insulating material layer provided outside the inner plate, and a heat insulating material outside the heat insulating material layer. A metal middle plate provided, a fireproof coating layer that is sublimated by heating applied to the outside of the middle plate and expands by endothermic decomposition, and the fireproof coating layer outside the fireproof coating layer. It is composed of a metal outer plate arranged with a space corresponding to the expansion.

It is composed of an intermediate plate 8. As the heat insulating material 7, a thickness of 50
mm blanket type kao wool (manufactured by Isolite Industry Co., Ltd.) was used.

On the outside of the middle plate 8 of the safe 5, a fireproof coating material 9 is further provided.
Was applied to a thickness of 4 mm. The fireproof coating material 9 is sublimated by heating, endothermic decomposition and expands. Here, Thermolag 330-1 (manufactured by Hitachi Cable, Ltd.) which is a fireproof coating paint based on a flame retardant polymer is used. did. Since the fireproof covering material 9 expands about eight times when heated, the inside of the rear body 2 made of aluminum is attached to the outside with a space of 32 mm as the expansion amount of the fireproof covering material 9. This structure has good crime prevention strength and workability, is particularly excellent in fire resistance, and there is no external problem described later.

If necessary, the adhesiveness with the intermediate plate 8 may be improved to
In order to have the anticorrosion effect of the above, a primer may be applied to the outer side thereof and then the fireproof coating 9 may be applied, or a topcoat for increasing the mechanical strength against impact vibration etc. on the fireproof coating 9 May be given.

As a procedure of assembling, after the safe 5 is manufactured, the heat resistant coating material 9 is applied and mounted on the floor of the truck chassis 1, and the van-shaped rear body 2 is mounted with a certain gap. The gap between the fireproof coating material 9 and the rear body 2 also functions to prevent damage to the safe 5, even if the rear body 2 is damaged due to an accident or the like. Also, the truck chassis 1 and the rear body 2 are usually replaced in 3 to 5 years, but the safe 5 can be used semi-permanently.
Can be used by replacing it with a new truck chassis 1 or rear body 2. Moreover, the reason why the aluminum outer plate 2a is used for the rear body 2 is to provide waterproofness and impact resistance, and also because it is a camouflage that is a problem in appearance and prevents it from being immediately recognized as a safe car from the outside. is there.

When this fireproof safe car is in a vehicle fire, first, the outer plate 2a of the rear body 2 can prevent the temperature from rising to some extent.

When the temperature reaches about 200 to 300 ° C., the heat resistant coating material 9 sublimes and absorbs heat from the surrounding atmosphere or the middle plate 8 or the like to lower the temperature. Ambient temperature is about 100 within 1 hour
Even if the temperature reaches 0 ° C., the temperature in the safe 5 can be maintained at 100 ° C. or lower. In the case of a normal vehicle fire, it is usual to extinguish the fire in about one hour. At this temperature,
Cash, securities, etc. stored in the safe 5 will not be burned. When water is discharged from the outside at this time, the temperature inside the safe 5 can be further lowered by about 20 to 30%.

Next, the overall structure of the safe 5 will be briefly described.
