Rail support wall specifications
Drawing notes
1)
See the lift installation (shop) drawings for rail bracket spacing and pit depth.
2)
Wall lateral support spacing:
•
For 2" x 4" studs, use 6 ft 10" (2090 mm) max.
•
For 2" x 6" studs, use 13 ft 6" (4120 mm) max.
3)
Sheathing installation: install sheets vertically full width of shaft or min. centred on rail brackets.
4)
Connectors to resist horizontal load but allow vertical movement. For wood, use 2" x ¼" cap screw lag bolts.
General specifications
G1
The design and construction of all work is to conform to the local applicable building code.
G2
Read the installation (shop) drawings in conjunction with all related architectural, mechanical, electrical, and
lift drawings as well as any other contract documents.
G3
The wall drawings have been prepared using engineering principles and the design loads that are applied by
the lift rails to the wall. However, the details and member sizes and the attachments to the structure should
not be construed as a complete design of the wall system. The contractor and/or the project engineer is
responsible to evaluate the other loads that are applied to the wall from the floor or roof system and modify
member sizes or connections as required by their analysis.
G4
Do not scale the drawings.
G5
See the lift installation (shop) drawings for service loads (including dynamic effects) which are:
•
Horizontal load parallel to the wall: 194 lbf (0.86 kN) for Infinity; 251 lbf (1.12 kN) for Infinity HD
•
Horizontal load perpendicular to the wall: 304 lbf (1.35 kN) for Infinity; 422 lbf (1.88 kN) for Infinity HD
G6
Wood: SPF NO 1/2 Mix
Concrete: 3000 psi (20 Mpa) @ 28 days. If exposed use 5% to 7% air content.
Anchor bolts: ASTM A307
Mortar: Type "S"
Masonry grout: 2100 psi (14 Mpa) high slump
Masonry block: 2100 psi (14 Mpa) on net area
G7
Wall to be installed plumb and square within 1/8" (3 mm) of top and bottom of shaft.
G8
Wall lateral support spacing (H) selected for maximum horizontal deflection of H/360 from rail loads.
Wood construction
W1
Separate wood from concrete with waterproof barrier or use pressure treated wood.
W2
Bridging maximum spacing: Load bearing or shear walls – 4 ft (1219 mm) c/c.
Nail or screw sheathing at 6" (152 mm) c/c at edges and 12" c/c to other members.
W3
Use 2.5" standard Ardox nails or 2" #12 screws.
Masonry construction
M1
All masonry construction to conform to applicable local standards
M2
Reinforce lintel blocks with 2 m-15 m bottom bars unless noted.
M3
Provide continuous ladder type joint reinforcement at 16" (400 mm) c/c.
