Breaking-in resistant panel

FIELD: panel structures, particularly used in safes and enclosing structures for sales registers and depositories.

SUBSTANCE: panel comprises metal walls, frame made as at least double-layered grid of longitudinal members and filler plates of impact-resistant crack-resistant heat-insulation material. The plates are arranged at least in some cells defined by longitudinal frame members. Longitudinal frame members are formed of shaped steel-rolled stock and/or of steel roll-formed shapes having angular, channel, I-shaped or Z-shaped cross-sections. End surfaces of filler plate ends abut longitudinal member flanges, which are perpendicular to metal walls. Filler plates are connected to flanges, which are parallel to metal walls by peripheral plate planes.

EFFECT: reduced metal consumption due to reduced weight along with maintaining high strength properties and increased breaking-in resistance.

The invention relates to structures, tamper-resistant, and can be used in safes and walling cash units and storage values.

Famous concrete element including a concrete core, a limited rolling profiles, which by means of connecting elements made of angular profile attached profiled sheets (EN 2122083 C1, 20.11.1998). This design has a high bearing capacity and considerable weight. In case of fulfillment of thin layers of concrete they can not withstand the dynamic shock that leads to a low resistance and burglary element as a whole.

Known also power panel, comprising a metal wall and a reinforcement cage in the form of the spatial grid is filled with concrete and attached at multiple points to the inner surface of the metal wall (EN 94008163 A1, 20.11.1995). This design is to meet the requirements of resistance to burglary contains a large mass of concrete, because thin layers of concrete cannot withstand dynamic impact. In addition, concrete has a low fracture toughness.

The closest analogue of the present invention is the product (the panel) for protection against burglary, including metal sheets, the bounding box-shaped cavity in which is placed a rod elements are made of metal which is a mini-bars, forming a lattice frame in which part of the cell is placed a filler from impact resistant, crack-resistant insulating material (EN 17057 U1, 10.03.2001). This design has a smaller weight in comparison with analogues, in which the filling material used in concrete, however, the presence of solid metal bars forming the frame, determines its high metal content. In addition, the fill material adjacent to the rods on the ends and not associated with them, which reduces the resistance to cracking of each individual layer of the panel.

The technical task of the present invention is to increase the grade resistance to cracking, and reduction of metal construction.

The problem is solved by the panel, tamper-resistant, including metal frame in the form of at least two-layer grid of longitudinal elements and plate filler from shock-resistant, crack-resistant insulating material, placed, at least in part of the cells formed by the longitudinal frame elements, which according to the invention the longitudinal frame elements are made of rolled shapes and/or profiles of steel roll-formed, and these car profiles and have a cross section in the form of area, channel, I-beam or z-section, and the plate filler adjacent end surfaces to regiment the m longitudinal elements, perpendicular to the metal walls and planes on the periphery - shelves, parallel metal walls.

Plate filler can be rigidly connected with shelves longitudinal members by means of threaded or adhesive bonding, as well as by means of nails.

On the surface of the plate filler flush with the shelves of the longitudinal elements can be placed a layer of refractory material.

The refractory material is a liquid glass with sand.

When the longitudinal frame elements made of the area or channel, part of them in each layer of the frame may be located in pairs symmetrically, and the elements of each pair are adjacent to each other shelves perpendicular to the metal walls, connected by welding to the frame elements adjacent layer or layers.

Plate filler placed in adjacent layers, bonded together by means of nails or screws.

Grille frame depending on the desired class burglar resistance (for example, from 1 to 7) may contain from two to sixteen layers of longitudinal elements.

As shock-resistant crack resistant insulating material can be used in any combination: wood, plywood, chipboards, fibre boards, cement-bonded particle boards, the ISU is ovalocyte plate, asbestos-cement plates, plates on the basis of polymeric materials with different fillers. Properties that determine the suitability of a particular material for use as a filler plates in this design, are resistant to burning, impact resistance and crack resistance.

Compared with the closest analogue, in which the longitudinal elements used metal rods, the execution of the longitudinal members of the frame of the profiles having different shaped cross-section (area, channel, I-beam, z -), can impede access to the filler plates around the perimeter of each layer by fixing the ends of the plates between the shelves profiles, or by attaching to the shelves through, for example, threaded connections. In addition, the construction made according to the present invention, has a lower intensity, since the meter of the profile or structural shapes 45-70% lighter longitudinal meter metal rod, with the same strength characteristics.

The invention is illustrated below in an example of embodiment with reference to the accompanying drawings showing the following :

Plate 3 filler can be rigidly connected with shelves 9 longitudinal elements 2 group is a rotary threaded connection 10.

On the surface of the plates 3 of the filler flush with shelves 9 longitudinal elements 2 placed a layer 12 of refractory material, which consists, for example, liquid glass with sand or any other suitable material, including asbestos, plaster or asbestos cement.

When the longitudinal elements 2 made of area 4 or channel 5, a portion of the longitudinal elements 2 in each layer of the frame may be located in pairs symmetrically, as shown in figures 1, 6, and the elements of each pair are adjacent to each other shelves 8, perpendicular to the metal walls 1, and connected by welding to the frame elements adjacent layer or layers.

Plate 3 filler placed in adjacent layers, bonded together by means of nails or screws 13.

Grille frame can contain, depending on the desired grade resistance to cracking, from two to sixteen layers of longitudinal elements 2 (e.g., I - two layers II - three layers, III - four layers IV - five layers, V - eight layers VI - twelve layers and VII - sixteen layers).

The Assembly of the panel is arranged in the following sequence.

Collect the insulating material 3, such as five-layer plywood with longitudinal elements, such as channel 4, and placed in a single layer on the panel size. Welded at multiple points in the channel 4 between them. On top of the first layer is perpendicular (or at an acute angle as shown in Fig.7) by a specified increment stack channel 4 of the second layer and at the intersection of weld them with the channels of the first layer, forming a grid with cells 130×130 mm On the insulating material 3 of the first layer flush with shelves 9 channels 4 of the first layer, the panel is placed liquid glass with sand (refractory material) 12. Set in the cell formed by the channels 4 of the second layer of insulating material 3. The following layers are collected in a similar way. The number of layers of the panel depends on the required class resistance to burglary. After assembling the required number of layers of assembled metal wall 1.
