Sound attenuation stud
The present invention relates to a sound attenuation stud. The stud includes two engagement portions for engaging within a building element. The stud also includes two sound attenuation formations located between the engagement portions. Each sound attenuation formation includes a first portion relative to which second and third portions extend. Preferably, each portion is either parallel or orthogonal with all the other portions.
1. A sound attenuation stud including two engagement portions for engaging within a building element and two sound attenuation formations located between the engagement portions, each sound attenuation formation including a first portion relative to which second and third portions extend.
2. A sound attenuation stud as claimed in claim 1 and having a uniform thickness, the lengths of the first, second and third portions being small enough to resist substantial deformation in use to thereby provide a structurally stable sound attenuation stud.
3. A sound attenuation stud as claimed in claim 1 , wherein the stud is shaped to engage with another like stud to form a box-like beam which resists deformation.
4. A sound attenuation stud as claimed in claim 1 , wherein the second and third portions extend orthogonally from the first portion.
5. A sound attenuation stud as claimed in claim 1 , wherein the sound attenuation stud includes exactly two sound attenuation formations.
6. A sound attenuation stud as claimed in claim 1 , wherein the second and third portions of a first one of the sound attenuation formations is of greater length than the second and third portions of a second one of the sound attenuation formations.
7. A sound attenuation stud as claimed in claim 1 , wherein the second and third portions are less than half the length of the engagement portions.
8. A sound attenuation stud as claimed in claim 1 , wherein the first portion of a first one of the sound attenuation formations is of greater length than the first portion of a second one of the sound attenuation formations.
9. A sound attenuation stud as claimed in claim 1 , further including a bridge portion bridging the two sound attenuation formations.
10. A sound attenuation stud as claimed in claim 9 , further including a pair of interconnection portions interconnected between respective engagement portions and sound attenuation formations.
11. A sound attenuation stud as claimed in claim 10 , wherein the bridge portion and interconnection portions are co-linear.
12. A sound attenuation stud as claimed in claim 1 , further including a pair of lip portions inwardly extending from respective engagement portions.
13. A sound attenuation stud as claimed in claim 1 , wherein each portion is generally straight, with each adjacent portion pair interconnecting in a curved manner.
14. A sound attenuation stud as claimed in claim 1 , wherein each portion is either parallel or orthogonal with all the other portions.
15. A sound attenuation stud including two sound attenuation formations, each sound attenuation formation including a first portion relative to which second and third portions extend.
16. A sound attenuation stud as claimed in claim 15 , wherein the sound attenuation portions are interconnected by a bridge portion.
17. A sound attenuation stud as claimed in claim 16 , further including: a pair of engagement portions for engaging within a building element; and a pair of interconnection portions interconnected between respective engagement portions and sound attenuation formations.
18. A sound attenuation stud as claimed in claim 17 , wherein each portion is either parallel or orthogonal with all the other portions.
19. A sound attenuation stud as claimed in claim 15 and having a uniform thickness, the lengths of the first, second and third portions being small enough to resist substantial deformation in use to thereby provide a structurally stable sound attenuation stud.
20. A sound attenuation stud as claimed in claim 11 , wherein one of the sound attenuation formations is of greater length than the other one of the sound attenuation formations.
21. A sound attenuation stud comprising:
a pair of engagement portions for engaging within a building element;
a pair of sound attenuation formations located between the pair of engagement portions, each sound attenuation formation comprised of a first portion from which second and third portions outwardly extend, and wherein one of the sound attenuation formations is of greater length than the other one of the sound attenuation formations;
a bridge portion bridging the pair of sound attenuation formations; and
a pair of interconnection portions interconnected between respective engagement portions and sound attenuation formations; and
wherein the bridge portion and interconnecting portions are substantially co-linear.
22. A sound attenuation stud as claimed in claim 21 , wherein the sound attenuation stud is shaped to engage with another one of the sound attenuation studs forming a box-like beam.
