The present disclosure relates to assembling systems, in particular acoustic panels fastening system and support structure thereof.
Existing solutions for fastening acoustic panels to plane surfaces or affixing acoustic panels on vertical structures are divided into two main categories: chemical fastening and mechanical fastening by screwing said panels.
Chemical fastening consists of a glueing process, wherein various types of adhesive substances are used, in particular glues suitable to the two surfaces to be joined. The quality of the adhesive substances/glues depends on the respective features of the surfaces and requires a drying period, during which the panels may suffer dislocations. Once the glueing process is dried and finished, it becomes a permanent solution, requiring scraping and treatment of the surfaces prior to any change in the used panels.
Existing mechanical solutions are based on screw support, passing through the panel. Affixation quality is defined by the quality of the wall, and of the material used in the construction of the wall itself. Given the nature of acoustic panels, that suffer dilatation and expansion, and are inherently subject to constant micro-vibrations, a screw solution requires maintenance. Changing the assembling scheme requires changing the positioning of the wall fastenings; and dismantling the system completely, with the possible damages and implicit wears.
Mechanical solutions correspond to removable fastening systems, allowing substituting the panels and resorting to physical supports in direct or indirect contact with the surfaces. There is a great variety of solutions of mechanical fastening available on the market, ranging from direct fastening of the panel to the plane surface resorting to screws or a stapler gun to solutions using more or less complex parts or support structures. Most solutions involve using rails or profiles allowing panels, Z-shaped clip-clip or other gravity fastening systems to fit in. Suspension systems are preferably suited to the particular case of horizontal fastening (ceilings).
These solutions illustrate the technical problem to be solved by the present solution.
The present disclosure relates to an acoustic panels fastening system simultaneously compatible with a vertical assembly and with fastening in horizontal plane surfaces, in particular ceilings, and vertical ones, in particular walls, this being therefore a universal system for all types of fastening: horizontal surfaces, vertical surfaces and vertical piling.
The disclosure herein presented comprises three particular advantages. The first advantage is allowing the assembly to be made easily; using a provided reference, plugs or fastening points are placed in key-spots in the desired surface. Therein fittings (clips or fitting-clip) are screwed. There is no more interaction with the surface. A beam is fitted in the fittings, in which the panels are subsequently fitted. The panels are fitted by means of two fittings, a “rail” and a fitting (clip or fitting-clip). The rail is screwed to the panel, having a groove for the fitting or fitting-clip. The panels are easily removed and reorganised.
For a suitable and effective installation it is necessary to guarantee a straight line between the two points. Therefore, the installation is independent of the state or level of the surface, allowing installation in curved surfaces and dihedral corners. The cavity created between the surface and the back of the panel creates an air gap, which not only increases the performance of the panel, but it also enables the possibility of assembling other utilities on the surface, in particular water and gas pipes, electrical cable trays, drastically decreasing the cost, time, and structural impact of an installation. The air gap also influences the thermal performance of the room.
The second advantage is the alignment between panels. After being assembled on the beam, a horizontal adjustment is possible, in particular sliding along the beam, and a vertical adjustment, in particular the fitting of the panel ensures a good junction between panels.
The third advantage is the uncoupling effect between panel and wall. Since there is no direct contact between the wall fitting and the panel fitting, there are several implications. There is a better performance with regards to low frequencies from the surface, since there is no mechanical transfer. There is also less wear in fastening the wall fitting, given the reduction in vibrations. Overall there is an improvement in the performance of the panels.
The fastening system herein disclosed is a durable system, user-friendly, it increases the performance of the adjunct system, that fulfils the requirements of international standards on construction and fire resistance, with possibility of being incorporated with other work aspects, reducing time, cost and impact of installations, as it can be incorporated with local materials, diminishing the necessary quantity to export, indirectly improving the environmental impact associated with the product.
The present disclosure thus ensures the alignment and fastening of acoustic panels on horizontal and vertical surfaces, in particular on walls and ceilings, respectively.
The present disclosure allows a faster assembling, with alignment adjustments in all directions and wherein the assembly quality is not dependent on the quality of the surface, that is, this disclosure differs from the fastening systems disclosed in the state of the art.
The disclosure herein presented is a durable fastening system, resistant to mechanical wear; it uncouples the panel from the surface, increasing the performance; it allows changing the panel arrangement; it is universal, any product that can be screwed with a small screw is compatible; easy disassembly for maintenance purposes or substitution of damaged parts; it creates an air gap around the space, with the proper implications of thermal and acoustic insulation; it doesn't require expert tools; it is a unique solution for all different fastening situations and needs—vertical surfaces, horizontal ones or vertical piling, in particular constructing a wall or barrier with the panels themselves.
The present disclosure is an economical solution from the point of view of production, since it uses the same type of supports and clamps both for the panels and for the surfaces; in the case of the vertical piling of panels for creating an acoustic barrier, it allows using small segments of tube, facilitating the assembly and diminishing the expedition costs; the assembly of the panels is easily made, with a simple fitting movement; it is easy and simple to install, by simply aligning adequately the tubular structures; it allows horizontal adjustment, in particular sliding along the tube, and vertical adjustment, in particular sliding the clamp in the support fastened to the panel, ensuring a perfect alignment between panels.
The acoustic panels of the present disclosure may be easily removed, substituted or reorganised, according to a possible need. The uncoupling between the panels and the wall brings several advantages, since the cavity created between the surface and the back of the panel creates an air gap allowing:
The disclosure is associated with a scale economy, with a single type of supports and clamps, both for panels and for surfaces; it allows using anti-vibration rubbers in the clamps.
The assembly of acoustic panels is characterised by an assembly is simple and quick, without needing to resort to specialised tools; it allows alignment adjustments in all directions; it allows changing the arrangement of panels; easy disassembly for purposes of maintenance or substitution of parts; it allows substituting the panels contrary to chemical fastenings; durable, not dependent on the quality of the surface; it allows the application to irregular surfaces; it uncouples the panel from the surface, increasing the acoustic performance; it allows the coexistence of other installations such as pipelines or electrical cable trays in the air gap between the panel and the surface.
The present disclosure comprises the use of a support tubular structure allowing clamps to fit in. On the other hand, these clamps are fitted in supports fastened, in particular with screws, to the acoustic panels, and to the surfaces that will receive the acoustic treatment. The same clamps are therefore the connecting element of the tubular structure both to the acoustic panel and to the walls.
A beam is a structural element functioning as a bar so that both terms may be used interchangeably.
