Description

[Detailed description of the invention] This invention relates to the structure of the frame of a safe for safe use and fire resistance.

This invention relates to the structure of the six-sided plate of the safe that forms a cube.

Therefore, the opening/closing of the entire safe and the door body, as well as their tight fitting parts, are outside the scope of this invention, and therefore a description thereof will be omitted.

The cubic frame that forms the safe is made up of six parts: the door, both side walls, rear wall, ceiling, and bottom.

This invention relates to the unit frame structure that constitutes each wall.

Conventionally, ultra-high heat flame radiators such as metal cutting machines have been used to destroy safes for the purpose of stealing.

Although conventional safes have a structure that can protect them from work using metal cutting machines, they often cannot provide complete protection when exposed to ultra-high heat flame release methods for a long period of time.

Even in this case, there are some that can sufficiently withstand the high heat caused by fire, while others are not as good as partial ultra-high heat destruction methods.

Therefore, this device was developed with the main purpose of creating a heat-insulating structure to prevent theft using an ultra-high-temperature flame radiator as a means of destruction. The basic conditions are that it can withstand the use of machinery, etc. and high heat from flames, etc., and on top of these basic conditions, it has a structure that can withstand ultra-high heat cutting.

Next, an embodiment of this invention will be described with reference to the drawings. The drawings show a partial cross section of the side walls of the safe body, and the basic structure is the side walls shown, the door body, the rear wall body, etc. , the ceiling body and the bottom body each have the same configuration, but even if the details of the door body are formed differently depending on the opening/closing mechanism and locking mechanism and the meshing relationship with the storage body, the basic configuration will remain the same. are the same.

The cross-sectional structure of the skeleton version A has a triple layered structure consisting of the front layer a, the inner layer C, and the middle layer C.
The intermediate layer C, which serves as a base when configuring the above, is also formed in a layered structure.

That is, a paste-like non-combustible heat-resistant sealing material 4 is applied to the gap and both surfaces of the lath 5 in a layered manner to form the middle layer, and the skin plate 3 made of steel plate is adhered to one side of the middle layer, and the other side can be press-formed. Then, a back plate 3' of a special steel plate having heat resistance, melting resistance, and male resistance is adhered to form an intermediate layer 0 plate of the unit body.

Ideally, the material of the skin plate 3 in this intermediate layer C should be made of special steel of the same quality as the back side plate 3', but in terms of the effect when it becomes the frame version A, the value of both is I can't see any difference.

On the other hand, unlike the above-mentioned intermediate layer C, the inner layer that forms the inner surface of the inner box of the safe is not formed as an independent unit like the above-mentioned intermediate layer C, but is made of special steel used for the back side plate 3' of the intermediate layer C. The interior panel 2 of the cabinet is used as the material, and the interior panel 2 of the cabinet is formed in advance into a five-sided body excluding the front door surface part as the interior of the safe before forming the inner layer, and the appropriate locations on each surface are appropriately placed. A lath 7 is installed through the gap piece 6 so that a desired parallel gap size is formed, and the intermediate layer C is connected to its back side plate 3' and the lath 7 through the lath 7 with an appropriately desired dimension.
are installed facing each other and parallel to each other, and foamed concrete 8 is filled with the lath 7 interposed between this back side plate 3' and the storage inner plate 2, and is combined with the intermediate layer C to form the inner side. Form a layer.

Furthermore, a reinforced concrete slab 11 is separately formed into a desired shape by using the lath 9 with spacing members 12 attached at required locations as aggregate, and is different from the skin plate 3 in the intermediate layer C described above. With steel plates made of the same material,
A safe outer casing is formed of the outer panel 1 of the cabinet in a five-sided structure excluding the front door surface portion, similar to the inner panel 2 of the inner layer, and the intermediate layer C and the inner layer are combined in this outer casing of the safe. The reinforced concrete slab 11 is inserted into the gap between the skin plate 3 in the intermediate layer C and the inner surface of the outer panel 1 of the storage body.
and the head of the gap member 12 buried in the reinforced concrete slab 11 is brought into contact with the inner surface of the outer panel 1 of the storage body. 13 to eliminate any voids and form the front layer a outside the intermediate layer C to constitute the frame version A.

Note that d in the figure indicates a joint location at the end of the door body A'.

This invention is constructed as described above, and the main body version A has a structure in which an intermediate layer C is provided between the front layer a and the inner layer. A layered coating is applied to the gap in the lath 5 and both sides thereof, and a skin plate 3 made of steel is applied to the outside of the layered surface of the non-flammable heat-resistant sealing material 4 on both sides, that is, the front side, and a special steel plate is applied to the back side. The fire resistance of the non-combustible heat-resistant sealing material 4 used here is that it is completely abnormal when heated up to 840 degrees Celsius in the fire resistance 3 powder test (JIS fire resistance test method). There is a result of "No", but this is a non-flammable heat-resistant sealing material 4
In the heat resistance test of a single item, as mentioned above, a lath was buried with this non-combustible heat-resistant sealing material 4, and a back plate 3' made of a special steel plate was attached to the back side of the skin plate 3 made of a steel plate as an intermediate layer. A heat-resistant flame release test was performed on the formed intermediate layer C itself, and it was found that due to the synergistic effect with the non-combustible heat-resistant sealing material 4, when the veneers such as the skin plate 3 and the back plate 3' were heated under the same conditions. However, no temperature rise phenomenon was observed, and when the heating limit of the heat-resistant material was reached during long-time flame release work and destruction occurred, the non-flammable heat-resistant sealing material 4 foamed, causing the nozzle of the ultra-high-temperature burner to Close.

Furthermore, if the burner is moved away to avoid the nozzle clogging phenomenon caused by the above-mentioned foaming state, the purpose of burn-off cannot be achieved.

In addition, even if the flame release operation is stopped under the above conditions and switched to a hip cutting machine or drilling machine, the heat generation phenomenon that occurs during the operation will cause the foaming state to occur again, preventing the movement of such equipment and achieving the purpose. Can not do it.

The above describes the test results of the destructive work of only the middle layer C veneer with the non-combustible heat-resistant sealing material 4 as the middle layer.

The main body version A of this invention consists of three layers, with the back side layer a and the inner layer closely attached to both outer sides of the intermediate layer C mentioned above. First, it starts with the outer panel 1 of the front layer a, but since the outer panel 1 is made of steel plates, it can be destroyed relatively easily, but it is formed with the next layer, the reinforced concrete slab 11. In the middle layer, the reinforced concrete layer has a lath 9 interposed therebetween as an aggregate, and the reinforced concrete layer continues again in the rear layer, and then reaches the skin plate 3 of the middle layer C.

At this stage, the diameter was much smaller than the destruction area of the stealing work hole drilled in the outer panel of the storage body in the front layer a, and the work efficiency became worse. Moreover, the reinforced concrete slab 11 that passed through
Since the broken tip of the inner lath 9 is exposed like the tip of a wire, even if it reaches the middle layer C, it is not easy to operate the equipment to destroy it, so it is difficult to operate a device to destroy it, and it is necessary to perform flame blasting work, or destructive work using a cutting machine, drilling machine, etc. Even if this is done, as mentioned above, only time will be wasted and the progress of the work will continue to decline.

In this way, the subsequent work includes the non-combustible heat-resistant sealing material 4, the lath 5, the non-combustible heat-resistant sealing material 4 again, and the back plate 3' using a special steel plate, followed by 8 layers of foamed concrete in which the lath 7 is embedded, and finally the special steel plate. Since the internal walls 2 of the warehouse were damaged, the destruction work required a long time and patience, and if the destruction work was for the purpose of stealing, the work would have to be interrupted and would therefore be unsuccessful. It is.

Furthermore, in the case of a fire with a different type of disaster, even if the intermediate layer C is constructed using only a single sheet of ordinary steel plate, the fire resistance ability against the high heat of a fire will still be the same as that of the conventional type. Its safety has been proven.

By fabricating only the door body A' together with the safe body under basically the same conditions and in a separate process on the body frame version A constructed as described above, all kinds of equipment and all means were taken to steal the work. However, it has the effect of being able to cope with this problem and achieve the purpose of fire protection and fire protection.
