Abstract

A sound deadening panel (10) consists of a structural layer (11) having a vibration absorbing layer (12) bonded thereto, the vibration absorbing layer (12) being disposed so to define gaps or cavities (14) which are distributed throughout the layer (12). When used in a flooring construction with the vibration absorbing layer (12) in contact with a continuous supporting surface (19), improved impact and air-borne sound deadening performance is obtained. The vibration damping material may consist of a resilient open-cell polymer. <IMAGE>

Description

SOUND DEADENING IN PANELS AND LIKE BUILDING STRUCTURAL PARTS This invention relates to panels and like building structural parts including boards, sheets, plates etc., all of which are hereinafter referred to simply as "panels"; and the invention is concerned with the construction of such panels and the sound deadening properties thereof.
The invention is also concerned with floor and/or wall and partition constructions incorporating such panels.
According to the present invention, there is provided a panel comprising a first layer of a material for performing a structural function of the panel, and a second layer comprising a vibration absorbing material disposed so as to define gaps or cavities distributed throughout said second layer.
The disposition of the vibration absorbing material so as to defined gaps or cavities distributed throughout the second layer provides increased freedom for expansions of the material within the second layer. Thus, the vibration absorbing capacity of the second layer is enhanced.
Further, according to the present invention, there is provided a floor construction comprising a panel as aforesaid or an assembly of such panels, laid with the vibration absorbing layer of each panel in contact with a supporting surface.
Further, according to the present invention, there is provided a floor construction comprising battens supported at intervals therealong on a series of panels each as aforesaid, each panel having its vibration absorbing layer in contact with a supporting base surface, and floor surface-defining members laid on the battens.
Further, according to the present invention, there is provided a wall construction or a partition construction comprising a panel as aforesaid, or an assembly of such panels, secured to a continuous surface with the vibration absorbing layer of each panel in contact with said continuous surface.
Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings in which: Fig. 1 is a perspective view of part of a panel in accordance with one embodiment of the present invention; Figs. 2 and 3 are views similar to Fig. 1, but showing second and third embodiments respectively; Fig. 4 is a sectional elevation showing part of a floor construction using a panel and in accordance with the present invention; and Fig. 5 is a sectional elevation showing part of a further floor construction with panels in accordance with the present invention.
In Fig. 1, a panel indicated generally by reference numeral 10, has nominal length and breadth dimensions 1000 mm by 500 mm and consists of a first layer 11 for performing a structural function of the panel 10, namely a sheet of conventional chipboard 20 mm thick. The panel 10 further consists of a second layer 12 of a vibration absorbing material disposed in mutually spaced strips 13 thus to define gaps 14 which are distributed throughout the second layer 12. Each strip 13 extends for the full length of the panel 10 (1000 mm) and is 50 mm wide and 12 mm thick. The material of each strip 13 is a resilient open-cell polymer having a static deflection of the order of 10 mm under a loading of 8000 pascals. The width of each gap 14 is 10 mm.
The strips 13 of vibration absorbing material are secured to the chipboard sheet 11 by means of any suitable adhesive.
Advantageous acoustic properties of the panel 10 are realised when, in use, the panel is placed with the vibration absorbing layer 12 in contact with a continuous or substantially continuous supporting surface as shown in Fig. 4. Both airborne and impact sound transmitted through the chipboard layer 11 as vibration will induce cyclic compressive and expansive movement in each strip 13. By providing the gaps 14 throughout the second layer, there is increased freedom for the material of the strips 13 to move and it has been found that this enhances the vibration absorbing capacity of the second layer.
The dimensions of the elements constituting the panel 10 are determined primarily with reference to the structural function of the chipboard layer 11 and the loadings thereon. Thus, the thickness of the chipboard layer 11 will for practical purposes be in the range 4 to 25 mm; and the length and breadth dimensions of the panel have upper/lower limits determined solely by simple practical considerations. The thickness of the strips 13 of vibration absorbing material will generally be in the range 4 to 25 mm; and the "stiffness" characteristic in the range 4 to 25 mm deflection under loading of 8000 pascals. Generally, the maximum width of the strips 13 will be in the region of 80 mm; and the minimum gap 14 dimension will be in the region of 2 mm.
In Figs. 2 and 3, parts corresponding with those in Fig. 1 are given the same reference numerals. In Fig. 2, the layer 12 of vibration absorbing material is disposed in the form of an array of blocks 15 with gaps 14 therebetween. In Fig. 2, the blocks 14 are illustrated as being of regular rectangular configuration. In a modification of the Fig. 2 embodiment, the blocks 15 are not regular and/or may be of circular or other rounded configuration. In Fig. 3, the layer 12 is illustrated as a sheet of vibration absorbing material having an array of regular apertures or cavities 16. The apertures or cavities 16 are effectively equivalent to the gaps 14. By providing the cavities or gaps throughout the second layer and in combination with an open-structured material, the sound deadening property of the panel is enhanced.Sound transmitted into each cavity or gap can be absorbed by adjacent portions of the open-structured material. In a modification of the Fig. 3 embodiment, the array of apertures or cavities 16 may be irregular and of rounded configuration. Also, in a further modification of the Fig. 3 embodiment, the layer 12 may be provided with cavities in the form of depressions distributed throughout the layer.
In Fig. 5 a floor construction consists of floor boards (floor surface-defining members) 17 laid on mutually spaced parallel battens 18 which are supported at intervals therealong on a series of panels 10 in the form of small platforms of which the vibration absorbing layers engage a concrete supporting surface 19. In the arrangement of Fig. 5, uneveness in the surface 19 is compensated by insertion of a shim 20 or wedges 21.
In each of the embodiments mentioned above, the gaps or cavities constitute a saving of the second layer material. It is in envisaged that, in certain versions of these embodiments, the variable parameters can be calculated to optimise the material saving and the acoustic performance.
