[0001] The present invention relates to a multifunction gas structural element, suitable
i.e. to realize structures for building and urban furniture (as for example coverings,
tunnels, safety barriers or support for protection slabs against the throw of objects),
and that can be used, also, to realize sound-insulating and sound-absorbing acoustic
barriers.
[0002] Realizing structures for the building and urban furniture using per-fabricated modular
elements manufactured out of metal, composite materials among which the reinforced
concrete) and polymers, is well known.
[0003] The mentioned conventional technique presents as limit the necessity of executing
on the site all the operations to realize the carrying structure of the building.
[0004] A second critical factor is represented by the construction weight of the structure,
if it raises itself on work of art.
[0005] An object of the present invention is to use a gas compressed inside cylindrical
cavities realized inside a structural element of the cited conventional technique
type, in order to confer rigidity, and consequent structural function, to the element
of which the cavities form integrating part.
[0006] Another object of the present invention is to reduce the construction weight of the
structural element, characteristic that turns out particularly important in the realization
of barriers or other manufactured articles on work of art.
[0007] A third object of the present invention is to provide, as application, a structural
element with sound-absorbing or sound-insulating characteristics.
[0008] A fourth object of the present invention is to provide a structural modular-type
element in order to minimize the operations to be executed on the existing infrastructures
and to reduce, at the same time, risks during the laying in work, with consequent
reduction of the production costs.
[0009] A fifth object of the present invention, which depends on the precedent, is the realization
of modular units possibly prefabricated, that can be arranged and differentiate according
to the various functional requirements, which require a minimum time of laying in
work.
[0010] On the basis of the invention, the innovative structural element reaches all the
stated objects and in particular performs its function (which is to resist to structural
loads and stresses or to form integrating part of a structure) more effectively in
comparison to what acquired by the state of the art, thanks to the fact it foresees
inside a conventional structural element a component "lightened" by the presence of
cavities that, filled with gas characterized by opportune values of the pressure,
they allow to obtain appropriate physical and mechanical characteristics (of rigidity,
resistance, sound absorption, etc.).
[0011] The above-mentioned characteristics arc warranted from the form and the nature of
the materials.
[0012] The option concerning the use of the inert gas can increase the conformity of manufactured
article with to the security qualifications either at level of elements and materials
or at level of building and of exercise.
[0013] By way of non-limitative example, a practical embodiment of the invention, illustrated
in the figure of the enclosed drawing table, is described.
- the figure 1 illustrates in section the typical structural clement according to the
invention.
[0014] With reference to the mentioned figure, the standard structural element, according
to the invention, generically indicated with (1) in figure 1, it is realized coupling
two side elements (2) in plastic, composite or metallic material, which constitute
the outside covering, with an carrying element interposed (3) between them constituted
from a layer in a material lightened by hermetic sealing cylindrical cavities (4).
[0015] In such a way the space inside the interspace turns out subdivided in several vertical
cells.
[0016] The layers like the walls of the cylinders can be realized with various materials
and variable thickness depending on the various functional requirements
[0017] Some or all the cells are filled with gas in order to confer rigidity and stability
to the structural element and the whole structure.
[0018] These are the schematic modalities sufficient to the expert person to realize the
invention, therefore in concrete application, we will be able to consider some variants
of them without prejudice to the substance of the innovative concept.
[0019] Therefore, with reference to the description which precedes and the enclosed table,
are expressed the following
1. Multifunction structural element, characterized in that it is it constituted from two parallel side layers in plastic, composite or metal
material between which are interposed one or more component lightened with cylindrical
cavities or tubing manufactured article.
The said cavity or manufactured articles subdivide the interspace between the side
elements in a plurality of cells, disposed in different manners and to various distances
in function of the application.
2. Multifunction structural element as claimed in claim 1, characterized by the fact that the cells in which the interspace is subdivided are hermetically sealed.
3. Multifunction structural element as claimed in claim 1 and 2, characterized by the fact that everyone or some of the cells in which the interspace is subdivided
can only be filled by compressible fluid, in general and also for structural functions.
4. Multifunction structural element as claimed in claims 1 and 2, characterised by the fact said cells are foreseen filled, to lighten more the structure and contain
the costs, with inert gas or simply air taking into consideration values of pressure
or degrees of vacuum opportune and compatible according to the various functional
requirements.
5. Multifunction structural element as claimed in claim 1 and one or more than the next
claims, characterized by the fact than the various layers like the walls of the cylinders (in the case of
cavities realized with tubing manufactured article) are foreseen realized with various
materials and variable thickness depending on the functional requirements.
The all one as described, illustrated, claimed and for the purposes there specified.
