Description

Acoustic panel for facades and ceilings.

The object of the present invention is a panel acoustics designed for application on the structures of roofs, generally and preferably, of ships and / or large premises dimensions, as well as in establishments and / or habitats of smaller dimensions, in order to configure a system of high sound attenuation, starting the absorption process acoustics at the bottom of the panel, which, remaining view will be decorated according to the needs of the builder or of the designer, describing the characteristics below Essentials of the mentioned acoustic panel.

Object of the invention

In general, the large volumes of construction covered, such as warehouses, sports centers, meeting rooms and musical performances, industrial buildings, etc., they need mitigating and absorbent elements that avoid phenomena of transmission and reflection of sound in ceilings and walls, so that the reverberation times are controlled, taking into account its subsequent use, as will be the activities recreational, sports, industrial, commercial, etc.

It is therefore necessary to place items capable of carrying out the aforementioned and described function, highlighting, in addition to this main feature, the fact of being self-supporting, thus facilitating its storage, handling, transport and placement.

State of the art

At present, the elements that are used, generally, to constitute that mitigating coating and Sound absorbing consist of three layers of such material such as wood, plasterboard or similar, glued on a frame Main, usually made of wood, called "cabio". Between these layers are sandwiched various insulating materials, such as wool of high density rock or other closed cell materials, such as polyurethanes, polyisocyanurates, etc.

On certain occasions, it is replaced, in the realizations that are carried out today, the last layer bottom by perforated plates, with low absorption capacity acoustics.

In current embodiments, the values of insulation does not exceed 30 dBA in the traffic noise of vehicles, the absorption being less than 80%, ie an "alpha sabine "of 0.8.

Present systems of enclosures " in situ " present the disadvantage that successive layers must be placed on the structure where the installation is carried out, requiring longer assembly times, which requires an overly marked construction planning for those times of construction. assembly of current insulation and sound absorption systems.

Description of the acoustic panels object of the invention

The acoustic panel object of this invention offers in practice the increase in the degree of sound insulation above acoustic values in vehicle traffic noise of the 42 - 43 dBA, increasing the absorption coefficients current acoustics above 80%, ie "alpha sabine" of 0.80.

It consists essentially of the object acoustic panel of this invention, on a top plate, of wood or steel, fixed on the metal frame or "wooden cup" on joints, preferably rubber or elastic neoprene: under this plate adhered or deolidarized there will be a membrane constituted by a heavy sheet of neoprene or similar material, a variable air chamber and immediately below a first block of acoustic and insulating fiber, such as rock wool or textile medium density, completed by a second block, identical in dimensions and composition to the first, equally solidarity or not to a lower membrane, and that rests all on another membrane self-supporting that will embrace the "cabio" through a board of elastic neoprene

Below this second block, and perfectly embedded in the space delimited by the sides of the "cabio", a block, preferably of fiber, is located acoustic, on whose lower face is supported or attached to a perforated veneer or wood plate, high absorption capacity acoustics.

As a variant embodiment, this last block lower may be an air chamber, similar to the one left located at the top of the panel.

Finally, the acoustic panel is characterized object of the present invention for having on the external face of the sides of the frame, called "cabio", of a design tongue and groove that ensures tightness, so that at place one panel next to another, the space between the two it will remain closed by those joints, avoiding the passage of both air flows like moisture.

The panel constituted by the different elements described in the previous paragraph, it is self-supporting and totally sufficient in its structural stability, so may be handled, both in storage and transport and placement in the final installation, which reduces the assembly and installation times of these acoustic panels, attenuating and sound absorbing, and consequently the costs of installation and transport.

In the attached drawings, and by way of example practical not limiting, an embodiment of the panel has been represented acoustic object of this invention, with reference in the rest of the description, to the figures attached.

In these drawings,

Figure 1 is a perspective view of a acoustic panel of the invention properly assembled; Y

Figure 2 is a schematic view and in section of the panel itself, thus showing all its components, providing, at one of its ends, a detail expanded, for clarity of the above.

According to the drawings, the acoustic panel for roofs (1), object of the present invention, is constituted by an upper plate (2), of attenuating material, fixed on the frame called "cabio" (3), which constitutes the structure self-supporting of the panel itself, on neoprene joints elastic (4). Under this top plate (2) adheres optionally, an attenuating membrane (7) being delimited below, at will an air chamber (5) and, below, a first block (6) of absorbent fiber and thermal insulation, such as the rock wool or medium density textile, solidarity or not lower membrane (9) consisting of a neoprene sheet or other similar material, completed all by a second block (8), identical in dimensions and composition and also adhered, as Desire to a lower membrane (9), resting the assembly on another membrane (10) that has bends to hug the faces interiors of the "cabio" (3), where some joints are located (11), elastic neoprene.

Embedded in the space between the side of the "cabio" (3) a block of acoustic fiber (12), under whose lower face is arranged, firmly adhered, a perforated plate (13), of veneer or wood, whose face external, the lower one, will be the visible face of the panel once installed, and on which the elements may be arranged decorative depending on the needs of the designer or the builder.

On the outer side of the sides of the "cabio" (3) includes grooves with sealing gasket (14), located horizontally and at the same level as the side that those of the other, in order to coincide on the surface of those contiguous external faces when placing a panel (1) next to the next, at the time of installation.

The self-supporting panel feature (1) will allow its placement fixed to the roof structures horizontal or inclined, and also on vertical surfaces, such as walls or walls, always attending to your sound insulation function.

Described sufficiently the object of the In the present invention, it should be noted that any variation in dimensions, appearance and exterior finish, as well as types of materials used in the practical realization of this panel acoustic, will not alter the essentiality of it, being summarized in the claims that follow.

Claims (3)

1. Acoustic panel for facades and ceilings, of self-supporting structure characterized by comprising an upper plate (2), of acoustic insulating material, fixed on the frame or "cabio" (3) that constitutes the self-supporting structure of the panel (1), provided an intermediate joint (4) and an air chamber (5) being delimited under said plate (2), and below a first block of insulating fiber (6), such as rock wool or medium density textile, following immediately below a second block of insulating fiber (8), optionally adhered to a membrane (9), of identical dimensions and also supported or fixed the assembly on a membrane (10) which has a fold that wraps the "cabio" (3), positioning in this fold a joint (11). 2. Acoustic panel for facades and ceilings, according to the preceding claim, characterized in that below the second block of insulating fiber (8), and perfectly fitted in the "cabio" (3), an acoustic fiber block (12) is located , which in some occasions may be an air chamber, and below whose lower face is located a plate (13), of sheet metal, perforated wood, or other different finishes visible from the outside. 3.
