AI Technical Summary

Benefits of technology

[0009]The present invention is based on a discovery that, by attaching a layer of a non-foamed, polymeric barrier sheet to the structural framework, desirable sound insulation can be achieved using a fraction of the sheet material used when covering the surface of a wall. The structural framework usually has a much lower surface area than that of the supported wall, and so the present invention may greatly reduce the cost of materials.

Problems solved by technology

The insulation of wall and floor structures against sound transmission is a recognised problem, particularly in multi-storey buildings such as flats and office buildings.
Although polymeric barrier sheets are effective sound insulators, they are often heavy and expensive to use.
This expense is partly due to the fact that large quantities of the sheets must be used in order to cover the surface area of the wall.

example

[0023]Using a transmission suite, the sound insulating properties of two plasterboard partitions were compared.

[0024]Materials

[0025]Sample 1

[0026]Sample 1 comprised a plasterboard partition system weighing 23.4 kg / m2 and having dimensions of 3600 mm wide×2400 mm high.

[0027]A plasterboard partition system 115 mm thick was screw fixed on to a timber frame on the receiver room side of the test aperture. The frame 40 mm deep and 65 mm thick was set on a bead of mastic and screw fixed to the perimeter of the test aperture.

[0028]The partition system consisted of 3 double leaf partitions each nominally weighing 67.5 kg. Partition panels were constructed of a self supporting timber frame with vertical timber studs and ‘noggins’. Plasterboard panels 2400 mm high×1200 mm wide×12.5 mm thick were screw fixed at ˜150 mm centres on to both sides of each frame construction (the resulting cavities remained unfilled). The outer and central partition panels had different frame dimensions; central fra...

Abstract

The present invention provides a structural member comprising a beam and, attached thereto, a sound insulating layer comprising a non-foamed, polymeric material. A method of obtaining such members is also provided.

Description

FIELD OF THE INVENTION[0001]This invention relates to a structural member for providing sound insulation in, for example, a wall or floor structure.BACKGROUND TO THE INVENTION[0002]Floors and partition walls are often constructed by fixing one or more panels to a metal or timber framework. In the case of a partition wall, the framework typically comprises vertical and horizontal structural members (sometimes referred to as “studs” and “noggins” respectively), to which the panels are nailed or screwed. Plasterboard is commonly used to construct non-load bearing walls and to line existing wall structures.[0003]The insulation of wall and floor structures against sound transmission is a recognised problem, particularly in multi-storey buildings such as flats and office buildings. Sound insulation is not only generally desirable, but is in many cases necessary in order for planning permission to be obtained.[0004]A variety of materials and techniques for achieving sound insulation have b...
