Description

SOUND INSULATING BUILDING CONSTRUCTION ELEMENT Field of invention The present invention relates to the field of construction elements for construction of a building such as an apartment building or a house, in particular to improvements in a beam, stud or upright construction element for simple and cost effective construction of walls and similar parts of the building, while providing good acoustic insulation between spaces separated by the wall.
Requirements and background
Building regulations typically determine the minimum requirements for all aspects of sound insulation of a building. As an example, the regulation "Byggteknisk Forskrift (TEK10)" of the Norwegian "Direktoratet for Byggkvalitet", which refers to the sound Class C of the Norwegian Standard NS8175, specifies in section 13-6 general design requirements on sound and vibrations to consider the need of occupants of a building for protection against noise and vibrations, and further in sections 13-7 and 13-11 the design requirements with regard to particularly sound insulation and vibrations, respectively. Further recommendations are also provided for providing acoustic properties of buildings that exceed the minimum requirements and satisfies need of parts of the public for even better sound insulation, in particular the insulation of air sound and step sound, than what are the minimum requirements set by regulating authorities, such as for example, what has been referred to as sound Class A or sound Class B of the Norwegian Standard NS8175.
Several different technical solutions, and combinations of those solutions, exist for providing a beam, stud or upright construction element for simple and cost effective construction of strong and sturdy walls and similar parts of the building, that also provide air sound and step sound insulation between spaces separated by the walls or similar building parts.
US5609006 discloses a wall stud including core elements and insulative materials enclosed within C-shaped frame members. A steel profile based wall stud named "Stalstender C 100 Db+" has been presented to the market by Norgips.
Steel profile based wall studs named "C+ Regel, Plusregel" and "CSP+ Regel,
Plusregel" have been presented to the market by Europrofil AB.

In document "522.51 lLydisolerende etasjeskillere med trebjelkelag i boliger", part II, by SINTEF Byggforsk, published September 2016, ISSN 2387-6328, is disclosed mounting of vibration isolation brackets, "lydb0yler", fixed with a center distance of 1.2 m along each joist, staggered every other beam for a span of 1.2 m between each bracket. An example of a vibration isolation bracket is marketed under the name "Lydb0yle D PAROC XFA 001".

US3950912A and NO142720, disclose a sound attenuating wall comprising a skeleton frame, surface layers secured thereto, skeleton frame members, and an insulation provided between the skeleton frame members and the surface layers, respectively. The skeleton frame members are formed by two elements which in point of strength act separately of each other and are interconnected by portions of material which are weak or slender in the direction of the plane of the wall. The insulation disposed in the wall fills out only part of the space therein.
However, other factors than good air sound and step sound insulation need to be considered, such as for example installation convenience and efficiency, handling and manufacturing, mechanical strength and durability, as well as cost and general building safety, but lately also environmental sustainability in terms of for example the possibility of use of eco friendly and/or recycled materials, and own recycl ability. Accordingly, there is a need for a sound insulating building construction element especially adapted for providing excellent sound insulation of a wall or other part of a building that also provides advantages with regard to the above identified and other factors considered important in the building industry presently and in the future.

The web part has first and second outer wing sections and a meandering center section, of which the first and second outer wing sections are affixed to respective ones of the first and second flange parts. The dimensions indicated in the illustration f figure 1 are typical for the building construction element of the invention as adapted to use as a sound or vibration insulating wall stud, in replace of any well known and frequently used wall stud of dimensions two by four inches.
In the following, the invention will be further explained with reference to a top view drawing in figure 2 of the novel web part of a building construction element according to the invention. In this illustration are recognized the meandering or wave shaped center portion, or spine, and the first and second wing portions generally aligned in a common plane as continuations of the respective ends of the meandering or wave shaped center portion. The meandering or wave shaped center portion, or spine, is advantageously generally shape like the letter "s", with the first and second wing portions extending from the center portion as continuations of the respective ends of the "s" shape, thereby providing a mechanical symmetry for symmetrical mechanical properties. The web part is advantageously fabricated from a sheet of steel, by punching, nibbling or similar method, an "H"-shaped blank, and subsequently shaping of the bar, which corresponds to the horizontal stroke, of the "H"-shape to form the meandering portion, or "spine", of the web part. The stems, which correspond to the vertical strokes, of the letter "H" shape are oriented in a substantially coplanar relationship, for example by maintaining their orientation in the plane of the blank.
In the following, the invention will be further explained with reference to the perspective view photography of figure IB of a short section of an actual wall stud embodiment according to the invention. In this illustration are recognized the first and second elongated flange parts that are substantially co-oriented, that is oriented along respective substantially parallel longitudinal axes, which in this embodiment are both made from laminated sheets of wood that are glued to each other, such as in a typical plywood construction, and the web part situated between the flange parts with first and second wings at least partially disposed in and attached to matching longitudinal slots formed into sides of the flange parts that are facing each other.
