Definitions
- the invention relates to an arrangement for protecting a structure, in particular a building, against impacts, with at least one layer of shock-absorbing material which irreversibly absorbs shock energy provided on a base. Furthermore, the invention relates to a method for producing such a layer of damping material .
- the main field of application of the invention is the shielding of nuclear facilities and of protective rooms against impacts, such as are caused, for example, by falling loads and by impacting vehicles, in particular crashing aircraft.
- concrete with embedded balls of expanded polystyrene has been used as the damping material.
- this material has properties that are not optimal from an environmental point of view. This is how polystyrene is flammable. It can also become radioactive and decay in an environment exposed to radiation.
- the damping material is not recyclable because it consists of organic and inorganic substances.
- the object of the invention is to remedy this and to increase the environmental compatibility of the shock absorption.
- the arrangement according to the invention is characterized in that the layer of damping material consists at least to a substantial extent of glass foam.
- Glass foam is non-flammable and does not emit vapors or gases when heated. It is also radiation-resistant and can also be recycled, so that there are no disposal problems. Long-term stability is also advantageous. Glass foam is closed-pore and therefore cannot absorb any contamination. The material is also inert against chemical attacks. It also contains no washable components. Above all, it is extremely cheap material that can also be easily made from waste glass. It should also be emphasized that the shock-absorbing properties of the protective layer can be set very precisely, since glass foam of different densities can be produced.
- Glass foam can be used as the sole material for the protective layer.
- the glass foam is incorporated as granules in a matrix material.
- the protective layer is in a very good position to remove working loads. This has not been the case with conventional concrete with polystyrene inclusions.
- three parameters are available for the precise setting of the shock-absorbing properties, namely, firstly, the density of the glass foam, secondly, the strength of the matrix material and finally the quantitative ratio between the two materials. The minimum thickness of the protective layer is determined from this and from the load to be expected.
- the glass foam can already be produced as granules during manufacture. There is also the possibility of curing the glass foam as a block or web and then granulating it.
- cement or a cement-bound mass is advantageously used as the matrix material.
- the protective layer then consists of purely inorganic materials, so that easy recycling is possible.
- the layer of damping material be composed of shaped stones.
- shaped blocks can be produced in different sizes and can be easily processed into protective layers of different thicknesses and extensions.
- the shaped stones can be designed as blocks of glass foam. It can also be blocks of glass foam granules embedded in matrix material.
- sealing glass foam with a block-shaped covering see, the glass foam in turn form a block within the envelope or can be present as loose granules.
- the layer of damping material is arranged as a potting layer on the base.
- the grouting material consists of a matrix material with integrated glass foam granulate and can be applied without problems, for example like normal concrete.
- the layer of damping material be arranged on the base as a bed of glass foam granulate.
- the manufacturing outlay is minimal. Nevertheless, this protective layer also has the property of being able to carry off traffic loads without problems.
- the various possibilities of the protective layer structure namely shaped blocks, casting compound, matrix integration and filling, can be combined with one another as desired.
- Several layers of the same or different types can also be arranged one above the other. Above all, there is also the possibility of assigning different shock-absorbing properties to different protective layer areas.
- the removal of the traffic loads can be improved by covering the layer of damping material with a covering, in particular a screed layer.
- a covering in particular a screed layer.
- the cover can also be used to set the shock-absorbing properties.
- the cover can consist of the materials customary in road construction.
- slabs can also be used, which are placed loosely or connected to one another over the entire surface or only over surface sections.
- the cover can also be used as an intermediate layer.
- a particularly simple manufacturing process is characterized in accordance with the invention in that a concrete with glass foam granulate as an additive is produced, poured onto the underlay and then allowed to harden, a screed layer preferably being poured onto the layer of damping material and then allowed to harden.
- the scope of the invention is not limited to nuclear facilities, shelters and the like. Rather, there is a large number of other sensitive systems for which such a protective layer can be advantageous. For example, military facilities and protective zones that must be secured against component crashes should be mentioned. Shielding banks from third-party interference is also an option. Another field of application is transport packaging for radioactive or other dangerous or protected goods, as well as transport facilities such as Locomotives, associated impact ramps and the like. In addition, shielding is required wherever blasting, demolition work and the like are carried out. Finally, test facilities of various types can also be so dangerous or endangered that they require special shielding.
