Can a shaft wall be load bearing?
USG Shaft Wall Systems are non-load bearing gypsum wall partition assemblies constructed from outside the shaft at each floor. The assemblies are constructed of gypsum liner panels friction fitted to studs in a progressive manner, with gypsum panels, gypsum fiber panels or cement board applied to the face.
What are shaft wall studs?
ClarkDietrich C-T Cavity Shaftwall Studs are rigid high-performance members engineered to maintain shaftwall integrity. C-T Studs are designed for use with 1″ thick gypsum shaftliner panels. Gypsum shaftliner panels are inserted into the stud flanges.
Can you stack shaft wall?
Is it permitted to stack 1” shaftliner panels in a cavity shaft system? Yes, when the height of the assembly exceeds the length of a liner panel, then one liner panel is stacked on top of the other. No joint treatment or blocking is required at the horizontal panel butt joint.
Can shaft wall be used horizontally?
I-Stud Cavity Shaftwall Systems can be erected horizontally and used as economical fire resistive assemblies for corridor ceilings, stair soffits, and protection for mechanical ducts. This System provides fire protection for mechanical ducts and has been tested from both sides.
Can an elevator shaft be structural?
Lift shafts will also extend below ground if they must serve one or more basement levels, or to house operating equipment. They are commonly found in commercial, public and other types of multi-storey building. They can form part of the structural core that stabilises buildings.
What are standard metal stud sizes?
Standard lengths are 10′, 12′ and 14′. Other lengths available upon request. Conventional metal studs are available in 25, 22, 20, 18, and 16 gauge steel for your convenience (1-5/8″ available in 20, 22 and 25 gauge only). Structural studs are also available.
Can Shaftwall be used horizontally?
Shaftwall can be specified for horizontal applications as a free-spanning membrane with no support from the soffit. The membrane can be constructed entirely from below and can achieve spans up to 5100mm and fire resistance up to 120 minutes.
What is the difference between a chase wall and a shaft wall?
Shafts are Fire Protected chases. Chases are vertical and hide pipes, wires, ducts, etc.
What is the purpose of a shaft wall?
Since the basic task of the masonry shaftwall is to support itself and provide fire ratings, it needs to be structurally sound and fire-resistant. Its dense mass provides good sound attenuation, keeping noise from the stairwell or elevator confined to the shaft.
How big should a lift shaft be?
Typically, they have minimum dimensions of 1500mm x 1500mm, and maximum dimensions of 2000mm x 3000mm; standard wall thicknesses can range between 125mm to 140mm.

What size is a 6 metal stud?
What size is a 6 metal stud? A 600S metal stud measures 6 inches on its web, or long face. Thus a metal stud taking the place of a two-by-four measures 1 5/8 by 4 inches, and a two-by-six, 1 5/8 by 6 inches — slightly fatter but the same depth as their wood equivalents. Click to see full answer.
