Installation
J-Runners
Position steel
runners at base and head with the short leg toward floor side
of wall. Securely fix runners to structural supports with power
actuated fasteners at both ends and 600mm maximum centres. With
steel frame construction, fix base and head runners and J-Runners
or E-Studs to columns and beams before steel is fireproofed. Remove
spray-fireproofing from runners and E-Studs before installing
Shaft Liner Panels.
Liner
Panels
Cut Shaft Wall Liner Panels 25mm shorter than floor-to-ceiling
height and install vertically between J-Runners. Pack Glass Fibre
Light Industrial Semi-Rigid Insulation into gap between Liner
Panels and head J-Runner. Where Shaft Walls exceed maximum available
panel height, position Liner Panel end joints within upper and
lower third points of wall. Stagger joints top and bottom in adjacent
panels and reinforce end joints with horizontal CH Stud.
CH
Studs
Cut steel CH Studs 15mm less than floor-to-ceiling height and
install between Liner Panels with liner inserted fully in stud
groove. Screw fix studs to runners on walls over 4.8 metres high.
E-Studs
Install full-height steel E-Studs or J-Runners vertically at T-intersections,
corners and columns. Install full-height E-Studs over Liner Panels
to both sides of closure panels.
Openings
Frame small opening cut in Liner Panels only with J-Runner to
full perimeter. For fire damper openings, frame with J-Runner
0.9mm uncoated steel thickness at sides, head and sill and reinforcing
as shown on drawings. Suitably frame all openings to maintain
structural support for wall.

Frames
Lift Landing
Door
Install floor-to-ceiling Jamb Strut to each side of door frame
to act as strut-stud. Fix strut-stud to floor and ceiling runners
with two 8 x 16mm Wafer Head Drill Point Screws. At door frame

straps with 10 x 16mm Wafer Head Drill Point Screws - two to each
strap.
Access
Panel Frames
Install floor-to-ceiling CH Stud to each side of single and multiple
access panel frame, to act as strut-stud. Fix strut-stud to floor
and ceiling runners with two steel pop rivets to each connection.Remove
floor runner flanges for full width of frame. Fix horizontal CH
Stud at head and sill of single access panel frame. Fix access panel
frame to floor and shaft sides of vertical and horizontal CH Studs,
with 3mm diameter steel pop rivets at 300mm centres.
