Description

Technical Field

[0001] This invention relates to the field of safes and vault wall structures, specifically to a construction process for a waterproof, cut-reinforced safe wall and vault wall structure. Background Technology

[0002] With the improvement of people's material and cultural living standards and the development of the market economy, people have more and more valuables such as valuable documents (such as bills, stocks, and bonds) and cash. In order to safely preserve valuables and documents, individuals and enterprises are using safes more and more frequently. Users hope to have a safe with high security performance, so safes are constantly being improved.

[0003] Generally, safes on the market include mechanical safes and electronic safes. Based on these two types, other types of combination safes have also emerged. However, these protective structures primarily address the opening mechanism of the door. While this improves anti-theft performance and ease of operation, the protection of the contents still relies on the cabinet body composed of the cabinet walls. Existing safes often use a plywood body, with metal plates as the outer shell and concrete or other structural fillers inside for anti-theft protection. This type of plywood cabinet body is easily damaged by tools such as abrasive wheels, flame cutting, hammering, impact drills, and oxy-fuel blasting guns.

[0004] To resist the aforementioned attack methods, safes are typically reinforced with thicker walls. However, this simple, thickened structure is vulnerable to targeted breaches. There are generally three types of safes: the first is a single-layer steel plate, offering the weakest protection, easily breached by a single portable power tool such as a drill, angle grinder, or cutting machine; the second is a thin carbon steel plate sandwiched with a concrete layer, offering stronger protection but unable to withstand simultaneous attacks from two or three different methods; the third is a thick reinforced concrete vault wall with a steel frame. While robust, this type is also susceptible to damage from modern portable hammer drills, water drills, and cutting machines. With advancements in technology and the continuous development of new mechanical tools, large tools are becoming increasingly miniaturized, posing a growing threat to safes and bank vaults, and allowing for increasingly rapid breaches.

[0005] According to the "GA38-2021 Bank Security Requirements," the minimum wall thickness for bank vaults must be 240 mm. The reinforcing steel frame must use hot-rolled ribbed steel bars with a nominal diameter greater than 14 mm (as per GB / T1499.2), arranged bidirectionally with a spacing of no more than 150 mm, and constructed with commercial concrete of at least C30 strength. Our company has developed a reinforced safe and vault wall structure based on these bank security requirements. While increasing strength, the structure also becomes more complex. The steel bars are spaced approximately 75-100 mm apart and reinforced with 15 mm mesh stainless steel. This type of construction cannot be achieved using ordinary methods and commercial concrete; therefore, a construction process that is efficient, convenient, and provides stable quality to meet the requirements needs to be developed. Summary of the Invention

[0006] To address the shortcomings of the aforementioned technical solutions, this invention proposes a waterproof, cut-reinforced safe wall and vault wall structure and construction process. The technical solution is as follows:

[0007] This invention proposes a waterproof, cut-resistant, reinforced safe and vault wall structure, comprising an outer steel plate and an inner steel plate, with a first middle steel plate and a second middle steel plate disposed between the outer and inner steel plates. The first middle steel plate and the second middle steel plate are spaced apart, with the first middle steel plate adjacent to the outer steel plate and the second middle steel plate adjacent to the inner steel plate. A plurality of steel rods are fixedly inserted through the outer steel plate, the first middle steel plate, the second middle steel plate, and the inner steel plate.

[0008] A first wire mesh layer and a second wire mesh layer are provided between the first middle layer steel plate and the second middle layer steel plate. The first wire mesh layer is adjacent to the first middle layer steel plate, and the second wire mesh layer is adjacent to the second middle layer steel plate. A first partition is provided between the first wire mesh layer and the second wire mesh layer to divide the area between the first wire mesh layer and the second wire mesh layer into several first partitions. A tungsten carbide anti-cut plate is fixed in each first partition.

[0009] Filler material is injected between the first middle layer steel plate and the outer layer steel plate, between the first middle layer steel plate and the second middle layer steel plate, and between the first middle layer steel plate and the outer layer steel plate.

[0010] As a preferred embodiment of the above technical solution, the inner surface of the inner steel plate is covered with a tungsten carbide anti-cutting plate, and the steel rod passes through the tungsten carbide anti-cutting plate and is fixed to the inner steel plate.

[0011] As a preferred embodiment of the above technical solution, a plurality of second partitions are provided between the first middle layer steel plate and the outer layer steel plate, and the second partitions divide the area between the first middle layer steel plate and the outer layer steel plate into a plurality of second partitions.

[0012] A plurality of third partitions are provided between the second middle layer steel plate and the inner layer steel plate, and the third partitions divide the area between the second middle layer steel plate and the inner layer steel plate into a plurality of third partitions.

[0014] As a preferred embodiment of the above technical solution, the tungsten carbide anti-cutting plates installed in two adjacent first partitions are perpendicular to each other. The longitudinally placed and transversely placed tungsten carbide anti-cutting plates are placed parallel to the longitudinally placed partition plate and the transversely placed partition plate, respectively. The partition plate and the tungsten carbide anti-cutting plates are connected by a support rod through the mounting holes. The support rod is spot-welded to the partition plate and the tungsten carbide anti-cutting plates to prevent the tungsten carbide anti-cutting plates from moving.

[0015] As a preferred embodiment of the above technical solution, the grouting material includes the following raw materials: water, C80 grouting material, 12-mesh corundum, 36-mesh corundum, and 3-5mm broken tempered glass.

[0016] As a preferred embodiment of the above technical solution, the grout further includes the following raw materials: zirconia ceramic beads and / or diamond cutting tools.

[0017] The construction process for the above-mentioned waterproof cutting-reinforced safe cabinet walls and vault wall structures includes the following steps:

[0018] 1) Drill blind holes on the inner side of the outer steel plate to locate the fixed position of the steel rod. The blind holes are randomly located to prevent the pattern of other steel rod positions from being found in case of damage. The steel rod is fixed to the blind holes by welding or threaded connection.

[0019] 2) Fix the outer layer plate of the steel rod with the steel rod side facing up, and weld the first middle layer plate through the hole to the outer layer plate after positioning it at the preset distance.

[0020] 3) After passing the first wire mesh through the steel rod and keeping it parallel to the first middle layer plate at a preset distance, weld the first wire mesh to the steel rod;

[0021] 4) Make positioning grooves in the longitudinal and transverse partitions of the first partition, assemble the longitudinal and transverse partitions crosswise to form several partitions, spot weld them into a whole, and set them on the first wire mesh. Spot weld the partitions to the first wire mesh to fix them.

[0022] 5) The tungsten carbide anti-cutting plates installed in two adjacent partitions are perpendicular to each other. The longitudinal and transverse tungsten carbide anti-cutting plates are placed parallel to the longitudinal and transverse partition plates, respectively. The partition plates and tungsten carbide anti-cutting plates are threaded through the mounting holes using support rods. The support rods are spot welded to the partition plates and tungsten carbide anti-cutting plates to prevent the tungsten carbide anti-cutting plates from moving.

[0023] 6) A second layer of wire mesh is installed on the upper part of the whole consisting of the partition longitudinal partition and the partition transverse partition. The partition is welded to the second layer of wire mesh, and the second layer of wire mesh is welded to the connecting steel rod.

[0024] 7) Pass the second middle layer plate with positioning holes through the steel rod, and weld it to the steel rod after maintaining a preset distance between the second middle layer plate and the second wire mesh. The positioning holes should be larger than the diameter of the steel rod to facilitate position adjustment and make it easy for the steel rod to pass through the holes.

[0025] 8) Weld fixing shims onto the connecting steel rods at a sufficient distance from the middle layer plate. Fixing shims can be welded every other steel rod.

[0026] 9) Pass the tungsten carbide anti-cutting plate through the steel rod and lay it flat on the fixing pad. Then cover it with the inner steel plate. Weld the inner steel plate firmly through the hole of the steel rod.

[0027] 10) Weld side plates to the three sides of the steel plate that is welded together to form a square box-shaped body with one end open;

[0028] 11) Place the container with the opening facing upwards, pour the prepared filling material into the container, and fill all three layers of the container. After 24 hours, weld the filling port closed with a steel plate.

[0029] As a preferred embodiment of the above technical solution, crushed tempered glass or ceramic is injected between the first middle layer steel plate and the outer layer steel plate, and grout is filled between the first middle layer steel plate and the second middle layer steel plate. Crushed tempered glass or ceramic is also filled between the first middle layer steel plate and the outer layer steel plate.

[0030] The grouting material includes the following raw materials: water, C80 grouting material, 12-mesh corundum, 36-mesh corundum, and 3-5mm broken tempered glass.

[0031] As a preferred embodiment of the above technical solution, the grout further comprises the following raw materials: zirconia ceramic beads and / or diamond cutting tools.

[0032] This invention provides a waterproof and cut-resistant reinforced safe and vault wall structure and construction process. The steel wire mesh layer, partition partitioning, and tungsten carbide cut-resistant plate arrangement can effectively prevent water cutting and greatly improve the security of the safe and vault wall structure.

[0033] This invention virtually eliminates the possibility of damage from existing portable tools compared to existing vault walls. The first layer uses a thick 304 stainless steel plate for protection, eliminating the possibility of flame cutting. Its thickness reaches the cutting limit of an angle grinder. Even if cut open, it cannot be removed due to connecting steel bars and layered steel plates, thus continuing to protect the underlying concrete layer. Even if removed, it could damage the concrete layer, but the partitions prevent the damage area from expanding. A repeating process is needed to increase the damaged area and create space for further damage to the deeper steel plates; otherwise, tools cannot be used to penetrate deeper layers. The tungsten carbide cut-resistant plate installed between the inner steel plate and the two middle layers of stainless steel mesh not only provides superior protection against common power tools such as drills, grinders, abrasive wheels, and flame cutting, but its material properties also offer strong protection against water cutting.

[0034] Explosion-proof wire mesh is made of 304 stainless steel woven wire mesh with a wire diameter of 2-3.0 mm and a mesh spacing of less than 1.2 cm. Experimental wire mesh uses 304 stainless steel woven wire mesh with a wire diameter of 3 mm and a mesh spacing of 1 cm. Its main function is to prevent blasting, damage from electric hammers and impact drills, and to protect the inner concrete layer from being damaged and removed. The wire mesh is placed in the middle layer of the wall, at a certain distance from the outer steel plate, greater than the cutting distance of an abrasive wheel cutter or angle grinder, so that it cannot directly threaten the wire mesh.

[0035] Experiments showed that because the outer layer of steel plate is protected, TNT will not pulverize the concrete into powder when it explodes, but will break it into pieces to the maximum extent. Because the middle layer of wire mesh is protected, the concrete cannot be removed when it is damaged, thus prolonging the damage time.

[0036] The specifications of the wire mesh are selected based on the diameter of the drill bits used for hammer drills, impact drills, etc. If the impact drill bit is too small, the destructive efficiency is too low; generally, the diameter of drill bits and hammer drill bits is 14 mm or more. Hammer drills and similar tools exert significant destructive force on concrete; arranging wire mesh effectively prevents damage to the concrete layer from these tools. Placing the wire mesh in the middle layer prevents direct damage from tools such as cutting machines and angle grinders, thus effectively protecting the concrete from further damage.

[0037] This technology uses double-layer steel wire mesh, which effectively reduces the possibility of damage to the walls of safes or vaults.

[0038] This invention addresses the miniaturization of high-destructive-performance tools, such as portable plasma cutters and small high-pressure water jet cutters. Data from numerous market surveys and practical experiments show that while existing portable devices effectively increase destructive power and speed, their power is limited, preventing prolonged operation. This invention incorporates tungsten carbide, a currently commercially available metal with extremely high hardness. However, its mechanical properties are relatively brittle. While it effectively prevents drilling, grinding, and high-temperature cutting, and extends water jet cutting time, it cannot prevent impact damage from hammering or explosions. The overall structural arrangement of this invention maximizes the protective effect of tungsten carbide. By combining tungsten carbide with mortar materials, and using stainless steel plates and wire mesh layers for the outer protection, and connecting the outer and inner steel plates with metal rods, the invention prevents the wall from being peeled off layer by layer or cut through piece by piece during destruction, thus effectively preventing wall damage.

[0039] Our company developed this safe and vault wall structure through on-site research, multiple destructive experiments, including TNT explosion experiments, and by studying various portable power tools and miniaturized destruction tools available on the market. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0048] This invention proposes a waterproof, cut-resistant, reinforced safe and vault wall structure, comprising an outer steel plate 1 and an inner steel plate 2. A first middle steel plate 3 and a second middle steel plate 4 are disposed between the outer and inner steel plates, with the first and second middle steel plates spaced apart. The first middle steel plate 3 is adjacent to the outer steel plate 1, and the second middle steel plate 4 is adjacent to the inner steel plate 2. A plurality of steel rods 5 are fixedly inserted between the outer steel plate, the first middle steel plate, the second middle steel plate, and the inner steel plate.

[0049] A first wire mesh layer 6 and a second wire mesh layer 7 are provided between the first middle layer steel plate and the second middle layer steel plate. The first wire mesh layer is adjacent to the first middle layer steel plate, and the second wire mesh layer is adjacent to the second middle layer steel plate. A first partition plate 8 is provided between the first wire mesh layer and the second wire mesh layer to divide the area between the first wire mesh layer and the second wire mesh layer into several first partitions. A tungsten carbide anti-cut plate 9 is also fixed in each first partition.

[0050] Filler material is injected between the first middle layer steel plate and the outer layer steel plate, between the first middle layer steel plate and the second middle layer steel plate, and between the first middle layer steel plate and the outer layer steel plate.

[0051] The inner surface of the inner steel plate is covered with a tungsten carbide anti-cutting plate 10, and the steel rod passes through the tungsten carbide anti-cutting plate and is fixed to the inner steel plate.

[0052] A plurality of second partition plates 11 are provided between the first middle layer steel plate and the outer layer steel plate, and the second partition plates divide the area between the first middle layer steel plate and the outer layer steel plate into a plurality of second partitions;

[0053] A plurality of third partitions 12 are provided between the second middle layer steel plate and the inner layer steel plate, and the third partitions divide the area between the second middle layer steel plate and the inner layer steel plate into a plurality of third partitions.

[0054] Crushed tempered glass or ceramic is poured between the first middle layer steel plate and the outer layer steel plate; grout is filled between the first middle layer steel plate and the second middle layer steel plate; and crushed tempered glass or ceramic is filled between the first middle layer steel plate and the outer layer steel plate. This arrangement of crushed tempered glass or ceramic helps to increase the distance between the two layers, creating a buffer layer, which in particular helps to buffer the blast force during an explosion, preventing the entire wall from bearing all the blast force.

[0055] The tungsten carbide anti-cutting plates installed in two adjacent first zones are perpendicular to each other. The longitudinal and transverse tungsten carbide anti-cutting plates are placed parallel to the longitudinal and transverse partition plates, respectively. The partition plates and tungsten carbide anti-cutting plates are connected through the mounting holes using support rods 13. The support rods are spot welded to the partition plates and tungsten carbide anti-cutting plates to prevent the tungsten carbide anti-cutting plates from moving.

[0056] like Figure 6 As shown, the tungsten carbide in the first zone is arranged in two layers. The middle layer is vertically arranged, with a low density; at least one layer is used in each area. The vertical surface of the tungsten carbide cut-resistant plate must not be easily cut by waterjet cutting. If the tungsten carbide cut-resistant plate is laid flat, it will be thicker, affecting its practicality. The second layer is an inner layer, laid flat on the inner surface, with a larger area to protect the inner steel plate as much as possible. The middle layer effectively prevents the inner carbide plate from being continuously cut.

[0057] The partition plate has openings or through holes on its surface to allow communication between the areas divided by the partition plate.

[0058] The first partition includes longitudinal partitions and transverse partitions. Each of the longitudinal and transverse partitions has a positioning groove. The longitudinal and transverse partitions are cross-assembled to form several partitions and then spot-welded into a whole.

[0059] A construction process for waterproof, cut-reinforced safe cabinet walls and vault wall structures includes the following steps:

[0060] 1) Drill blind holes on the inner side of the outer steel plate to locate the fixed position of the steel rod. The blind holes are randomly located to prevent the pattern of other steel rod positions from being found in case of damage. The steel rod is fixed to the blind holes by welding or threaded connection.

[0061] 2) Fix the outer layer plate of the steel rod with the steel rod side facing up, and weld the first middle layer plate through the hole to the outer layer plate after positioning it at the preset distance.

[0062] 3) After passing the first wire mesh through the connecting steel rod and keeping it parallel to the first middle layer plate at a preset distance, weld the first wire mesh to the steel rod;

[0063] 4) The longitudinal and transverse partitions are equipped with positioning grooves. The longitudinal and transverse partitions are cross-assembled to form several partitions and then spot-welded into a whole. The partitions are then placed on the first wire mesh and spot-welded to the first wire mesh for fixation.

[0064] 5) The tungsten carbide anti-cutting plates installed in two adjacent partitions are perpendicular to each other. The longitudinal and transverse tungsten carbide anti-cutting plates are placed parallel to the longitudinal and transverse partition plates, respectively. The partition plates and tungsten carbide anti-cutting plates are threaded through the mounting holes using support rods. The support rods are spot welded to the partition plates and tungsten carbide anti-cutting plates to prevent the tungsten carbide anti-cutting plates from moving.

[0065] 6) A second layer of wire mesh is installed on the upper part of the whole consisting of the partition longitudinal partition and the partition transverse partition. The partition is welded to the second layer of wire mesh, and the second layer of wire mesh is welded to the connecting steel rod.

[0066] 7) Pass the second-layer middle plate with positioning holes through the steel rod, maintaining a preset distance between the second-layer middle plate and the second-layer wire mesh, and then weld it to the steel rod. The positioning holes should be larger than the diameter of the steel rod to facilitate position adjustment and allow the steel rod to pass through. The positioning holes should be 2-3 mm larger than the diameter of the steel rod to facilitate position adjustment and allow the steel rod to pass through the positioning holes. If the positioning holes are too large, the steel rod will not be able to bend sufficiently and will not be able to be welded to the middle steel plate as a whole.

[0067] 8) Spot weld the fixing shims 14 onto the connecting steel rods at a sufficient distance from the middle layer plate. The fixing shims 14 can be welded every other steel rod.

[0068] 9) Pass the tungsten carbide anti-cutting plate through the steel rod and lay it flat on the fixing pad. Then cover it with the inner steel plate. Weld the inner steel plate firmly through the hole of the steel rod.

[0069] 10) Weld side plates to the three sides of the steel plate that is welded together to form a square box-shaped body with one end open;

[0070] 11) Place the container with the opening facing upwards, pour the prepared filling material into the container, and fill all three layers of the container. After 24 hours, weld the filling port closed with a steel plate.

[0071] Therefore, the filling material is specifically: crushed tempered glass or ceramic is injected between the first middle layer steel plate and the outer layer steel plate; grout is filled between the first middle layer steel plate and the second middle layer steel plate; and crushed tempered glass or ceramic is filled between the first middle layer steel plate and the outer layer steel plate.

[0072] The above-mentioned grouting material includes the following raw materials: water, C80 grouting material, 12-mesh corundum, 36-mesh corundum, 3-5mm crushed tempered glass, zirconia ceramic beads, and diamond cutting tool.

[0073] The grouting material is mainly composed of high-strength adhesive grout, abrasion-resistant materials, cut-resistant materials, and strength-reinforcing materials, compounded in appropriate proportions. The main material is C80 pressure grout, which serves as both the adhesive and the main material after curing, exhibiting good flowability, high strength after curing, and excellent adhesion. 12-mesh and 36-mesh brown corundum abrasives are used instead of river sand as aggregate to increase the grout's strength after curing and achieve abrasion and abrasion resistance against grinding wheel cutting. Crushed tempered glass, zirconia ceramic beads, and scrap diamond cutting tools are used as large aggregates to increase the grout's explosion-proof strength and its resistance to drilling, cutting, mechanical cutting, and waterjet cutting after curing. To achieve the highest strength, abrasion resistance, drill resistance, and explosion-proof properties, the specific proportions of each material are appropriately adjusted to achieve optimal performance.

[0074] 1. Standard type, suitable for various models of safes and vaults.

[0075] The specific usage ratio is as follows:

[0076]

[0077] It has moderate strength, good toughness, good resistance to drilling and mechanical cutting, and strong explosion-proof capability.

[0078] 2. Reinforced type, suitable for various models of safes and vaults.

[0079]

[0080] It has high strength, moderate toughness, strong resistance to drilling and mechanical cutting, some waterproof cutting performance, and strong explosion-proof capability.

[0081] 3. Drill-proof, waterproof, and cut-resistant reinforced type, suitable for various models of metal safes and vaults.

[0082]

[0083] It has high strength and moderate toughness, and has strong resistance to drilling and mechanical cutting. It is also more waterproof and has strong explosion-proof capabilities.

[0084] This invention provides a waterproof and cut-resistant reinforced safe and vault wall structure and construction process. The steel wire mesh layer, partition partitioning, and tungsten carbide cut-resistant plate arrangement can effectively prevent water cutting and greatly improve the security of the safe and vault wall structure.

[0085] This invention virtually eliminates the possibility of damage from existing portable tools compared to existing vault walls. The first layer uses a thick 304 stainless steel plate for protection, eliminating the possibility of flame cutting. Its thickness reaches the cutting limit of an angle grinder. Even if cut open, it cannot be removed due to connecting steel bars and layered steel plates, thus continuing to protect the underlying concrete layer. Even if removed, it could damage the concrete layer, but the partitions prevent the damage area from expanding. A repeating process is needed to increase the damaged area and create space for further damage to the deeper steel plates; otherwise, tools cannot be used to penetrate deeper layers. The tungsten carbide cut-resistant plate installed between the inner steel plate and the two middle layers of stainless steel mesh not only provides superior protection against common power tools such as drills, grinders, abrasive wheels, and flame cutting, but its material properties also offer strong protection against water cutting.

[0086] This invention addresses the miniaturization of high-destructive-performance tools, such as portable plasma cutters and small high-pressure water jet cutters.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
