Description

Technical field

The invention relates to a building safe part, in particular a wall, ceiling, floor and door, consisting of reinforced concrete in which a steel plate is cast.

BACKGROUND OF THE INVENTION

In the construction of safes are currently used both armor walls, eg. made of steel panels of greater thickness and concrete walls with different types of reinforcement and filler.

For concrete walls, the base material is high strength concrete or special concrete based on epoxy or polyurethane. These walls, used primarily in the construction of chamber safes, are generally reinforced with a dense network of reinforcing steel, possibly with other reinforced elements and inserted steel plates.

SUMMARY OF THE INVENTION

Increasing the degree of intrusion resistance and destruction of the safe is solved by a building safe part, especially a wall, ceiling, floor and door, consisting of reinforced concrete, in which the steel plate is embedded, the essence of which is that the steel plate is placed on the side to the inner space of the safe, the inner side of the steel plate being provided with spines oriented outward from the inner space of the safe.

The main advantage of the building safe component according to the invention is that when attempting to drill an opening into a safe, the mandrels complicate the drilling, since the drilling tool is diverted and damaged when the drilling tool contacts the mandrel. They also make it difficult to break concrete.

To increase the effect of the mandrels, it is advantageous if the mandrels taper conically outwardly from the interior of the vault.

In order to additionally increase the resistance of the basic design, it is advantageous that the reinforcement is placed on the mandrels and that at least one hollow body is spatially randomly placed in the concrete, filled with hardly machinable material bodies, or of machinable material.

In order to impair the flow of molten metal resulting from an attempt to burn the steel plate, it is preferable that the smooth side of the steel plate be covered with sheet metal.

In order to improve the resistance to penetration into the safe using explosives, it is advantageous if a reinforced concrete layer is placed in the interior of the safe near the steel plate.

Since the building safe box can be made not only on site by assembling and casting into the ready formwork, but can be transported to the final destination, it is therefore advantageous for the building safe box according to the invention to be placed in a frame consisting of the bottom plate of the front sidewall. , rear side panel and two fronts to create a prefabricated part.

Overview of the figures in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an example of a basic embodiment of a building safe component according to the invention, FIG. 2 is a cross-sectional view of a structural vault member with additional strength enhancing elements; FIG. 3 is a sectional view of a prefabricated embodiment of a building safe member according to the invention, and FIG. 4 shows the same embodiment in plan view.

DETAILED DESCRIPTION OF THE INVENTION

The building safe part according to FIG. 1 consists of a steel plate 2 which is located on the side facing the interior of the vault 1. The inner side 3 of the steel plate 2 is provided with mandrels 4 which are oriented outwardly from the interior of the vault 1 and also taper conically in this direction. The rest of the volume of the building safe part is made of high-strength concrete 5, in which the mandrels 4 are cast. The building safe box can comprise both the walls of the safe, the ceiling, the floor, and possibly movable openings such as doors.

The building safe part according to FIG. 2 is provided with additional elements to further increase the degree of intrusion and destruction of the safe. A concrete reinforcement 7 is welded on the mandrels 4 and a hollow body 6, in this case a shaped polyethylene tube filled with steel balls, is spatially randomly placed in the high-strength concrete 5 due to the difficult location. Corundum or slag bodies 8 are added to the high-strength concrete 5 in a layer above the inner side 3 of the steel plate 2. The high-strength concrete 5 is in this case so-called. "Drôtobetón". The smooth side of the steel plate 2 is covered with brass sheet 13, thanks to which good heat conduction impedes the flow of molten metal resulting from the attempt to burn the steel plate 2. In the interior 1 of the vault, a steel reinforced concrete layer 14 with mesh 15 is located.

The building safe box is assembled either on site, by arranging the reinforcement in the formwork and then pouring concrete, or the building can be made as a prefabricated part from which the walls, ceiling and floor are assembled.

The prefabricated embodiment of the building safe part according to FIG. 3 and 4 consists of a frame formed by a bottom plate 9, a front sidewall 10, a rear sidewall 11a and two fronts 12. The building safe member according to an embodiment of the invention is then placed in the frame. The rear side 11 has the negative shape of the front side 10, which makes it possible to easily connect the individual prefabricated parts.

Industrial usability

The building safe part according to the invention can be applied in the construction or additional cladding of safes, both of large chamber and of smaller size safes. The building safe box can be made on site using formwork or can be delivered in the form of prefabricated parts that speed up the construction of safes.
