Description

High strength stratified product of application in security elements, as well as products obtained With that material.

Object of the invention

The object of the present invention consists of a stratified material formed by various elements of different nature, among whose characteristics is the high strength and low weight compared to similar products of the state of the art

This stratified material will be suitable for manufacture of safety boxes, autonomous safes or modular, reinforcement panels, security doors or any another product that requires high physical security.

Background of the invention

They are known in the state of the art high strength stratified products used as a barrier security in safes, security doors as armored doors, etc., elements that are usually constituted by plates or iron plates in whose interior high strength material is placed which is usually concrete.

This product meets the safety standards for this type of applications, but instead has other defects I get that they are difficult to overcome just like the high weight of these materials and their high thickness, which make Products made with these materials have some quite noticeable limitations of use, as they are, first of all the location site of these elements that has to be a site of high strength or high strength forging since the weight reached is extreme, and secondly due to the dimensions so extraordinary of these products, the outer dimensions of these security features such as safes, etc. must be very high to obtain an appropriate internal capacity for Use as a safe.

European patent is known EP-0308298 that provides a special shield for safe comprising a plate based on refractory steel Fracture resistant by classic torch, one or more torch-resistant refractory grafts with metal contribution, being wrapped in refractory steel, the structure and the distribution inside the steel of these grafts are such that the plate comprises a series of zones, distributed over the whole thereof, separated by other areas where the thickness of the Steel is different.

Object of the invention

The object of the present invention consists of a high strength and low weight stratified material, thereby that its high strength is comparable to that of those materials employees in the construction of armored doors, safes or equivalent applications.

More specifically this product in your application to safes is able to conform to grade IV of resistance to total or partial access according to the UNE EN standard 1143-1: 98. Among these features the product It is highly resistant to mechanical drilling, highly resistant to the use of cutting radials, it is equally resistant to the thermal lance that prevents product perforation and also turns the enclosure into a heat resistant enclosure by incorporating a layer of athermal material that protects the interior from fire and high temperatures.

The product in question proposed by the invention it consists of a stratified product formed by a series of stainless steel parts, sheets or panels, chosen this material due to its high mechanical resistance, forming these pieces or sheets a sandwich structure between which it is initially placed and in progression from the outside inwards a piece of reinforced polyester inside with steel mesh that has some extreme properties to its penetration by mechanical means as well as to the torch.

This polyester with reinforced mesh is a material commercial known for other applications that conforms by the hot rolling of polyester sheets between the which has a steel wire mesh, resulting in end of the process a unique polyester piece whose interior is find embedded metal mesh or steel mesh, constituting by itself a high strength reinforced final material.

The product is completed with another inner layer, It is made of athermic material between two layers or steel plates stainless formed by a layer of wood, chipboard, plywood, or material with similar characteristics that confer the fundamental properties of being a product that protects the interior of the enclosure from the high temperatures at which the exterior of the enclosure can be subjected.

These plates thus made by means of this stratified material can be joined together to form a enclosure, which is easily achieved by the proper weldability of stainless steel forming the walls Exteriors of this product.

This product is also suitable for realization of integral and inviolable enclosures forming their walls through an integral construction of this type without any type of seam, joint or weld that could weaken the final resulting product.

This product is equally suitable for realization of safety safes since its walls offer high resistance to penetration of the classic media of violation or rupture of such safes as are the means drilling mechanics such as the use of radials or the torch penetration

This product is suitable for the realization of armored and fireproof doors that preserve the interior of homes or enclosures of fire and attempted violation of their inside.

\hbox{peso.}

This product, in addition to its high strength, is surprising because of its low weight compared to the current technical means of similar application, since compared to concrete-based laminated doors, the difference in weight is 60% less than that of traditional doors which makes this structure suitable for other applications that were not currently used due to its high

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1 represents in section the material object of the invention.

Figure 2 represents the practical execution of a closed enclosure or safe made of a material such as shown in figure 1.

Preferred Embodiment of the Invention

Figure 1 shows a typical example in section of the material object of the invention, in which they are first seen place the three sheets constituting the sandwich walls which includes the piece in section, such as the three plates or sheets of steel (1), (2) and (3) which in a practical embodiment are plates AISI 430 stainless steel 3 mm thick, enough to offer an important mechanical resistance inside the enclosure.

Between these stainless steel plates is placed from outside to inside a first reinforced polyester plate of for example 12 mm. thick with 3 expanded steel mesh mm occluded or embedded inside.

This state of the art product is manufactured by hot lamination of two polyester plates between which is placed a metal mesh, the polyester so heated Makes the steel mesh penetrate into its bosom and in turn remain stuck the two polyester sheets leaving a unique material that is a piece of polyester whose breast is occluded or embedded in expanded steel wire mesh.

This polyester piece offers a high resistance to cutting, radial penetration as well as a great fire resistance reaching high resistance by example to the thermal lance, traditional method of forced opening of safes and armored doors.

The second material placed inside of The door or safe consists of a material plate athermal (5) which is a great insulator of heat, consisting of example on a wooden board, chipboard or plywood that besides physically preserving it becomes a thermal barrier protective of the safe against any fire produced, preserving the contents of said safe from high temperatures that could be occurring or caused from the outside. This plate (5) may be constituted by one or more plates of athermal material for example with a thickness of 19 mm.

A safe or armored door or wall executed with this structure conforms to grade IV of resistance to total and partial access according to the UNE EN standard 1143-1: 98 on safety and resistance.

Figure 2 shows the typical construction of a safe or safe with a panel made for the purpose of the invention, in which an integral construction is developed, observing the construction of an integral interior wall (3), a intermediate wall (2) and an outer wall (1) made said stainless steel plates or plates AISI 430 high resistance.

Highlights of this sandwich construction are the reinforced polyester plate with expanded steel mesh (4) and the Flame retardant material plate (5) placed in one position inside.

The total thickness in walls, floor and ceiling could be about 40 mm with this type of construction, except for example of the box-entry hinges that is 43 mm in the upper, lower, left and right side frame.

The union of the whole box is done through the welding of the different metal bodies creating three units different, outer body, intermediate body and body inside.

All its surfaces have a anchor between panels by connecting cylinders (6) welded between the outer plate (1) and the inner one (3), cylinders that can be of a diameter for example of 10 mm.

The body of the safe has a frame rigid manufactured by plate (7) and joined by internal welding to the body of the box.

Building a safe with these technical characteristics means considerable weight savings, savings that can be estimated at approximately 60% compared with boxes that meet the same safety specifications and that would have been made with a typical steel construction and concrete.
