Generally, the existing safes on the market include mechanical safes and electronic safes, and some other types of combined safes are derived based on the mechanical safes and the electronic safes, but the protection structure of this type mainly aims at the opening mode of the cabinet door, and is beneficial to improving the anti-theft performance and the convenience of operation, but still needs to rely on a cabinet body consisting of cabinet walls for protecting the contents. The prior art safe body adopts a sandwich plate body, the sandwich plate body takes a metal plate body as a shell plate, and concrete or other structural filling bodies are filled in the sandwich layer for anti-theft protection, and the wall of the sandwich plate body is easily damaged by attack tools such as grinding wheel cutting, flame cutting, hammering, impact drilling, oxygen melting gun (air explosion gun) and the like.
In order to resist the attack mode, the wall of the safe is thickened generally, but the simply thickened safe body has a simple and single structure and is easy to break through in a targeted manner. The existing wall cabinets are generally three, the first one is a single-layer steel plate, the protection performance is the weakest, and the wall cabinets can be damaged by using the existing single portable electric tool, such as continuous drilling points of an electric drill, cutting of an angle grinder and a cutting machine, and the like; the second mode is a mode of clamping concrete layers by carbon steel thin steel plates, which has stronger protection performance, but cannot support two to three damage modes to be damaged simultaneously; and thirdly, the wall state of the heavy vault is formed by pouring reinforced skeleton concrete, and the wall of the heavy vault is thick but is not damaged by the combination of modern portable electric hammers, water drills, cutting machines and the like. Along with the progress of the present technology, a large number of novel mechanical tools are continuously researched and developed, the large tools are gradually miniaturized, and the large tools bring more and more threat to the present safe and bank vault and the damage speed is faster and faster.

The reinforced safe wall and vault wall structure developed by the present department according to the bank precaution requirement has the advantages that the strength is enhanced, and meanwhile, the structural complexity is also improved. The arrangement space of the steel bars is about 75-100 mm, and the steel bars are reinforced by using stainless steel meshes with the hole pitch of 15mm, and cannot be constructed by using a common construction method and commercial concrete, so that a construction process which can reach the construction requirement with high efficiency, convenience and stable quality is required to be developed.

Compared with the existing wall of the vault, the invention almost eliminates the possibility of damaging the existing portable tool. The first layer uses thick 304 corrosion resistant plate protection, has stopped flame cutting's possibility, and thickness has reached the cutting limit of angle mill, even cut the back, owing to have connecting reinforcement and layering steel sheet to connect, can not take off, and it can continue to protect lower floor's concrete layer. Even if the concrete layer can be destroyed after being taken down, the partition board is used for protecting, the destruction area can not be enlarged, the destruction area can be enlarged only by repeating the destruction action once, and a space is created for the destruction of deeper steel plates, otherwise, tools can not be used for destroying deeper layers. The tungsten carbide cutting-preventing plate additionally arranged between the inner side of the inner layer steel plate and the middle two layers of stainless steel nets not only has more excellent protective capability on common electric tools such as drills, grinders, grinding wheel cutting, flame cutting and the like, but also has the characteristics of material performance, and has very strong protective capability on water cutting.
The explosion-proof steel wire mesh is made of 304 stainless steel woven steel wire mesh with the wire diameter of 2-3.0 mm and the mesh spacing of less than 1.2 cm. The steel wire mesh for experiments is woven by adopting a wire diameter of 3 mm and a spacing of 1 cm 304.

The steel wire gauze is arranged in the middle layer of the wall, has a certain distance from the outer layer steel plate, and is larger than the cutting distance of the abrasive wheel cutting machine and the angle grinder, so that the steel wire gauze cannot be threatened directly.
Through experiments, the outer layer is protected by the steel plate, concrete cannot be vibrated into powder during TNT blasting, the concrete is blasted into fragments to the greatest extent, and the concrete cannot be drawn out during the protection of the middle layer steel wire mesh is damaged, so that the damage time is prolonged.
The specification of the steel wire mesh is used as a reference according to the diameters of drill heads of electric hammers, percussion drills and the like. If the impact bit is too small, the damage efficiency is too low, and the diameter of a common bit and an electric hammer is more than 14 mm. The electric hammer, the impact drill and other tools have very large damage to concrete, and the arrangement of the steel wire mesh can effectively prevent the electric hammer, the impact drill and other tools from damaging the concrete layer. The steel wire mesh is arranged on the middle layer, so that tools such as a cutting machine, an angle grinder and the like cannot be directly damaged, and the damage of concrete is effectively protected.
In the technology, the double-layer steel wire mesh is used, so that the possibility that the safe or the wall of the vault is damaged is effectively reduced.
The invention aims at the miniaturization of the existing high-damage-performance tools, such as portable plasma cutting machines, small-sized high-pressure water cutting machines and other devices. In the data obtained through multiple market researches and practical experiments, the conventional portable equipment has the characteristics of limited power, incapability of long-time planning and the like although the damage capability and speed can be effectively improved. The invention increases the arrangement of tungsten carbide, which is a metal material with extremely high hardness and practical in the market at present, but has the disadvantage of relatively brittle mechanical energy, and can effectively prevent the effects of drilling, grinding, high-temperature cutting, prolonging the water cutting time and the like, but can not prevent impact damage such as hammering, blasting and the like. According to the invention, the protective effect of tungsten carbide can be maximized through the integral structure arrangement, tungsten carbide and mortar materials are combined, a stainless steel plate and a steel wire mesh layer are used for outer protection, and a metal connecting rod is used for connecting an outer layer steel plate with an inner layer steel plate, so that walls cannot be peeled layer by layer during damage, and cannot be cut one by one after the walls are penetrated and damaged, thereby effectively preventing the damage of the walls.
Through field investigation, multiple destructive experiments including TNT blasting experiments, the safe and the wall structure of the vault are developed through researching various portable electric tools and miniaturized destructive tools which can be purchased in the prior market.

The tungsten carbide cutting-preventing plate additionally arranged between the inner side of the inner layer steel plate and the middle two layers of stainless steel nets not only has more excellent protective capability on common electric tools such as drills, grinders, grinding wheel cutting, flame cutting and the like, but also has the characteristics of material performance, and has very strong protective capability on water cutting.
The invention aims at the miniaturization of the existing high-damage-performance tools, such as portable plasma cutting machines, small-sized high-pressure water cutting machines and other devices. In the data obtained through multiple market researches and practical experiments, the conventional portable equipment has the characteristics of limited power, incapability of long-time planning and the like although the damage capability and speed can be effectively improved. The invention increases the arrangement of tungsten carbide, which is a metal material with extremely high hardness and practical in the market at present, but has the disadvantage of relatively brittle mechanical energy, and can effectively prevent the effects of drilling, grinding, high-temperature cutting, prolonging the water cutting time and the like, but can not prevent impact damage such as hammering, blasting and the like. According to the invention, the protective effect of tungsten carbide can be maximized through the integral structure arrangement, tungsten carbide and mortar materials are combined, a stainless steel plate and a steel wire mesh layer are used for outer protection, and a metal connecting rod is used for connecting an outer layer steel plate with an inner layer steel plate, so that walls cannot be peeled layer by layer during damage, and cannot be cut one by one after the walls are penetrated and damaged, thereby effectively preventing the damage of the walls.
Through field investigation, multiple destructive experiments including TNT blasting experiments, the safe and the wall structure of the vault are developed through researching various portable electric tools and miniaturized destructive tools which can be purchased in the prior market.
