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.
According to the requirements of GA38-2021 for bank safety precautions, the wall thickness of a banking warehouse is as low as 240 mm, a steel bar framework uses hot rolled ribbed steel bars with nominal diameters larger than 14mm in GB/T1499.2, the bidirectional arrangement distance is not larger than 150mm, and commercial concrete with strength not lower than C30 level is used. 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.
