Modular reticular structures, expandable and re-modulable over time according to your needs
Space reticular structures, Lightweight, easy to be packed, transported, assemblied
The spatial reticular structures by Omnia Spatial Structures are suitable for multiple solutions:
The basic concept of each of our structures is the same: grids and diagonals are produced to measure, flattened at the ends and drilled, and finally combined with the use of bolts and fasteners following geometrical patterns, mainly of pyramidal type that make the structures rigid and lightweight, but at the same time resistant and drawing strength from the intrinsic rigidity of the triangular frame.
Despite the conceptual repetitiveness, the system is very customizable: the size of the grids to be used can vary, ranging from smaller diameters such as . 27 and 33 mm, to the standard ones (42 and 48 mm.) up to larger sizes such as 60 or 89 mm., for large industrial roofings.
Omnia staff also recommends the length of the grids to obtain a thick or wide weft, based on the aesthetic preferences, but above all the RAL colour that best meets the final aesthetic objective.
The roofing above the structure may be in corrugated or insulated metal sheet panels, covered in turn with slate or bituminous sheath, if required; while for the structures needing more care, such as a canopy, the final closure can be achieved with glass.
Omnia structures are safe and long-lasting, simple and geometric, they are strong and rigid, but at the same time lightweight, they allow to realise long spans thanks to a limited number of supports.
Even the Omniablok structures have similar characteristics such as strength and rigidity, but they are not customizable in the dimension of the diameter of the elements and this turns into the advantage of being able to determine the structure's weight:
The spatial reticular structures by Omnia Spatial Structures can be extended and re-moulded in their shape.
Even when the work is finished, it is possible to extend and increase the area of a reticular structure, or modify its shape or even disassemble it and then mount it again in another position.
Often, the designs and studies of the engineers and Omnia staff carried out on certain orders, are conceived taking into account a possible extension of the structure or a future junction between two structures.
A fundamental characteristic, as well as advantage, of the spatial reticular structures, is that they are suitable to cover large areas using elements of reduced dimensions, and very lightweight, with respect to metallic carpentry and reticular trusses-based implementations.
The stacking of grids and diagonals in iron baskets makes it possible to optimize the space.
Let's consider a practical example of an Omnia trapezoidal spatial reticular structure shipping on a tractor-trailer of 13.6 x 2.5 metres:
The project includes a structure of 50x20 m. occupying an area of 1,000 m²; 4,000 grids and 4,000 diagonals are required, whose overall weight is equal to 20.600. kg., hence 20.6 kg / m².
The example describes the lightweight of the structure compared to the dimension and emphasises at best the simplicity of transport.
Moreover, the extreme ease of the Omnia system allows to reduce the installation times to a minimum: the assembly phase of the nodes, indeed, does not require any attention from the operator regarding the squaring or leveling, as the interlocking of the various elements tightened by bolts and fasteners allows for self-adjustment and perfect alignment of the entire structure.
The same applies to the Omniablok system, easily transportable in iron baskets or pallets with elements no longer than 1.6 / 1.8 metres.
The mounting of the Omniablok structures is even faster thanks to the jointing of the grids in the Omniablok by means of a single central M16 screw, which allows the assembly in a day of 700 photovoltaic modules on a sloped roof and 250 photovoltaic panels on a flat roof.
The extreme simplicity in assembly allows us to send our structures all over the world.
Our Omniablok photovoltaic panel bearing system provides great resistance against the wind.
The structure, entirely connected, forms a single body and this allows the installation without drilling the roofing.
The only mandatory steps are for single-pitch roofs where it is necessary to drill at the ridge point. This, however, doesn't present a risk of infiltration, it is intended instead to prevent the structure from slipping.
Omnia's technical staff analyses each plant in its geographical location (address and house number of the place of installation) and, if required, certifies its static resistance according to the regulations of the State where it is installed by providing a technical report.
We attach an important testimony concerning a whirlwind that hit our province on September 24, 2012.
The climatic phenomenon caused evident damages to numerous buildings, in particular in the industrial zone of Brescia, the wind tore roofs, gutters in metal sheet, knocked down prefabricated walls and caused the breaking of doors and windows.
One of our installations is located on one of these buildings, the plant featuring more than 3000 panels was installed through bearing on the roofing without any type of fixing to the roof. Despite the incident, the chassis has not undergone any solicitation; some photovoltaic module got damaged by the fragments of metal torn from the roof of the plant and from the neighboring ones, but none of them was torn from its housing.
Following the photos of the plant after the natural phenomenon.
