Description

ACOUSTIC PANEL FIXING SYSTEM AND SUPPORTING STRUCTURE

Technical Domain

[0001] The present disclosure relates to mounting systems, in particular acoustic panel mounting systems and their supporting structure.

state of art

Existing solutions for fixing acoustic panels to flat surfaces or affixing acoustic panels to vertical structures fall into two main categories: chemical fixing and mechanical screw fixing of said panels.

Chemical fixation is a bonding process in which various types of adhesive are used, in particular adhesives suitable for the two surfaces to be bonded. The quality of the adhesives / adhesives depends on their surface characteristics and requires a drying period during which the panels may displace. Once the bonding process is dry and finished, it becomes a permanent solution, requiring scraping and surface treatment before any change to the used panels.

Existing mechanical solutions are based on the bolt support that runs through the panel. The quality of the display is defined by the quality of the wall, and the material used in the construction of the wall itself. Because of the nature of acoustic panels, which undergo expansion and expansion, and are by nature subject to constant micro-vibration, a screw solution requires maintenance. Changing the mounting scheme requires changing the placement of the wall mountings; and dismantle the system completely, with possible damage and implied wear.

Mechanical solutions correspond to removable fastening systems, allow replacement of panels and use physical supports in direct contact. or indirect with the surfaces. There are a wide variety of mechanical clamping solutions available on the market, ranging from direct panel clamping to the flat surface using screws or a staple gun to solutions using more or less complex support structures or parts. Most solutions involve the use of rails or profiles that allow the panels to snap together, or Z - clip or other gravity clamping systems. Suspension systems are preferably suited to the particular case of horizontal fixation (ceilings).

These solutions illustrate the technical problem to be solved by this solution.

General description

The present disclosure relates to an acoustic panel mounting system which is both compatible with vertical mounting and mounting on horizontal flat surfaces, in particular ceilings, and vertical surfaces, in particular walls, as such. a universal system for all types of fastening: horizontal surfaces, vertical surfaces and vertical stacking.

The disclosure now presented has three distinct advantages. The first advantage is that it allows for easy assembly; Using a supplied reference, anchor points or anchor points are placed at key points on the desired surface. These are clipped hardware ("clips" or clip-hardware). There is no more interaction with the surface. A bar fits into the fittings into which the panels are subsequently fitted. The panels are fitted by means of two fittings, a "rail" and a hardware ("clip" or clip-hardware). The rail is bolted to the panel and has a hardware or clip fitting. The panels are easily removed and rearranged.

For a proper and effective installation it is necessary to ensure a straight line between two points. Thus, the installation is independent of the state or level of the surface, allowing installation on curved surfaces and dihedral corners. The cavity created between the surface and the back of the panel creates an air box, which not only increases the panel performance, as it leaves the possibility of mounting other utilities to the surface, in particular water, gas pipes, electrical wire rails, dramatically decreasing the cost, time, and structural impact of an installation. The air box also influences the thermal performance of the room.

The second advantage is the alignment between panels. Once mounted on the bar, horizontal adjustment is possible, in particular by sliding along the bar, and vertical adjustment, in particular the panel's own hardware ensures a good joining between panels.

The third advantage is the decoupling effect between panel and wall. Since there is no direct contact between wall hardware and panel hardware, there are several implications. There is better performance over low frequencies from the surface as there is no mechanical transfer. There is also less wear and tear on the wall fitting, as vibration is reduced. In general there is an improvement in the performance of the panels themselves.

[0012] The fastening system now disclosed is a durable, user-friendly system, enhances the performance of the adjunct system, which meets the requirements of international building standards and fire resistance, and can be incorporated with other construction features, reducing the time, cost and impact of facilities, as can be incorporated with local materials, reducing the amount required to export, indirectly improving the environmental impact associated with the product.

The present disclosure thus makes it possible to ensure the alignment and fixation of acoustic panels on horizontal and vertical surfaces, in particular on walls and ceilings, respectively.

[0014] The present disclosure allows for quicker assembly with alignment adjustments in all directions and where the quality of the assembly is not dependent on the surface quality, ie this disclosure departs from the fastening systems disclosed in the state. of art.

The disclosure now presented translates into a durable fastening system, not subject to mechanical wear; uncouples the surface panel, increasing performance; allows panel layout changes; is universal, any product screwed by a small screw is compatible; easy disassembly for maintenance or replacement of damaged parts; creates an air-gap around the space, with the proper implications of thermal and acoustic insulation; no specialized tools required; It is a unique solution for all different mounting situations and needs - vertical, horizontal or vertical stacking surfaces, in particular by building a wall or barrier with the panels themselves.

[0016] The present disclosure is an economical production solution as it uses the same type of brackets and clamps for both panels and surfaces; In the case of vertical stacking of panels to create an acoustic barrier, it allows the use of small pipe segments, facilitating assembly and reducing shipping costs; The assembly of the panels is made easy, with a simple snap gesture; It is easy and simple to install simply by properly aligning the tubular structures; allows for horizontal adjustment, in particular by sliding along the pipe, and vertical adjustment, in particular by sliding the clamp on the bracket attached to the panel, ensuring perfect alignment between panels.

The acoustic panels of the present disclosure can be easily removed, replaced or rearranged as needed. The decoupling between the panels and the wall has several advantages, as the cavity created between the surface and the back of the panel creates an air box that allows: better acoustic performance at low frequencies;

the use of anti-vibration rubber clamps, further enhancing acoustic performance;

the application of panels aligned on uneven surfaces;

mount other utilities to the surface (pipes and electrical rails), reducing the cost, time, and structural impact of an installation.

[0018] Disclosure is associated with economies of scale with one type of brackets and brackets for both panels and surfaces; Allows the use of anti-vibration rubbers on the clamps. The mounting of the acoustic panels is simple and quick to assemble without the need for specialized tools; allows alignment adjustments in all directions; allows panel layout changes; easy disassembly for maintenance or replacement of parts; allows replacement of panels unlike chemical fixings; durable, not dependent on surface quality; allows application to uneven surfaces; uncouples the panel from the surface, increasing acoustic performance; Allows other installations such as piping or electrical trunking in the air box between the panel and the surface.

The present disclosure comprises the use of a tubular support structure that allows the fitting of clamps. These clamps are in turn fitted to brackets fixed, in particular by screws, to the acoustic panels, and to the surfaces to be acoustically treated. The same clamps are thus the connecting element of the tubular structure to both the acoustic panel and the walls.

[0021] A bar is a structural element with beam function so that both terms can be used interchangeably.

The present disclosure relates to the acoustic panel support structure comprising one or more fastening bars and one or more fastening elements wherein the fastening element comprises:

a rail to attach to the acoustic panel;

a clip fitting slidably connected to the rail along a first sliding axis;

wherein clip-hardware comprises a clip for slidably attaching to a tie bar along a second sliding axis and

wherein the bar or tie bars are configured to be fixed to a flat surface.
