What is a deflection head detail?
Deflection heads are used within GypWall metal stud/ShaftWall partitions when needing to allow for movement (up, down or both) within the structure at the head of a partition. This movement (or deflection) is created by live and dead loads on the floor or roof above.
What is deflection head in construction?
Criterion supplies a range Deflection head track, these are used on all walls exceeding 4800mm in height and may be specified in any wall system to permit for vertical movement of ceiling.
What is stud deflection?
The deflection joint is the distance between the top of the stud framing to the underside of the substrate above (floor or roof member), as defined by the project’s architect or structural engineer.
What is a Gypframe?
The modern, engineered alternative to traditional timber and blockwork construction, Gypframe-based wall, ceiling and floor systems are quicker and easier to install, whilst meeting the highest performance requirements. Gypframe profiles are manufactured using the patented UltraSTEEL® process and conform to EN 14195.
How does a deflection track work?
Slotted deflection track relies on the metal studs being fastened to the track through slotted holes in the track legs. The studs must be fastened so they can slide within the track. Over tightening the fasteners will prohibit movement. Advantages: This is the simplest track system to install.
What is a deflection gap?
In order to prevent any transfer of axial load between the structure and the stud, a gap is placed between the web of the deflection track and the top of the stud. This gap must allow for construction tolerances, material tolerances, in addition it must provide for upward and downward movement of the structure.
What is a deflection track for?
Protect Your Walls While Cutting Cost. Steeler Deflection Track is an economical alternative for ceiling connections of non-load bearing walls. Our deflection track is engineered to allow for ceilings to deflect under loading without affecting the wall underneath.
What are furring channels?
Furring Channel is a batten used in conjunction with specified clips to provide a stable framework for fixing plasterboard to walls and ceilings.
What is slotted track used for?
Slotted track allows the vertical movement of the building and prevents axial load transfer to the wall studs. OEG Slotted Track is used in exterior curtain walls or non-load bearing walls.
What is a slip track?
A slip track is a channel section (typically the top track) of a non-load bearing or curtain wall framing assembly that is fastened to the primary structure, but left unconnected to the vertical stud members. Stud horizontal reactions are resisted by the slip track flange.
What’s another name for furring channels?
Hat Channel is technically known as a 7/8” Drywall Furring Channel.
What kind of deflection Head do I Need?
In this video we’ll be installing a 15mm downward deflection head with a 60-minute fire rating, incorporating single layer 15mm Gyproc FireLine plasterboard. Cut and fix 19mm Gyproc CoreBoard to the back of 72 DC 60 Channel with 35mm drywall screws.
How to install deflection head details on gypwall metal?
This detail is based on 15mm downward deflection, so there will be a minimum plasterboard overlap of 7mm onto the CoreBoard. Cut and fix GFS1 Fixing Strap to the metal studs with Wafer Head Drywall Screws.
Why do you need a deflection head on a partition?
The partition system below needs to accommodate this movement without transferring load onto the metal studs. We offer a range of head details that allow the top of the partition to move independently of the metal studs, whilst also maintaining the structural performance and any fire resistance required.
How big is a Knauf deflection head fire seal?
