D.

Plumb, align and securely attach studs to flanges of both upper and lower runners, except that in the case of interior, non-load bearing walls where studs need not be attached to upper or lower runners.

E.

Splices in members other than top and bottom runner track are not permitted.

F.

Provide temporary bracing where required, until erection is complete.

INSTALLATION - NON-AXIAL LOAD-BEARING CURTAIN WALLS A.

Runners shall be securely anchored to the supporting structure as shown on the drawings.

B.

Jack studs or cripples shall be installed below window sills, above window and door heads, and elsewhere to furnish supports.

C.

Lateral bracing shall be provided by use of gypsum board and gypsum sheathing or by horizontal straps or cold-rolled channels. Bracing shall conform to Section D3 of the AISI North American Specification (NAS).

D.

Provisions for structure vertical movement shall be provided where indicated on the drawings prepared by the engineer of record.

E.

Handling and lifting of prefabricated panels shall be done in a manner so as not to cause distortion in any member.

INSTALLATION - SHAFTWALL FRAMING: RUNNERS, STUDS AND LINER BOARDS A.

Attach J-Runners plumb with one another, long leg on shaft side, at floor and structure overhead using power-driven fasteners located 2 inches (51mm) from each end and 24 inches (610mm) o.c. between. Cut jamb J-Runners or E-Studs not less than 3/8 inch (10mm) nor more than 1/2 inch (13mm) less than distance from floor to structure above. Position J-Runners or E-Studs at wall structural jambs. Do not attach to floor or overhead J-Runners.

B.

With steel frame construction attach J-Runners to beams and J-Runners or E-Studs to columns prior to fireproofing application. Where fireproofing is more than 1 in. thick, position Z-Clips at jambs no more than 4 inches (102mm) from floor and structure above and no more than 24 inches (610mm) o.c. between. Attach Z-Clips to steel frame with power-driven fasteners. Attach J-Runners and E-Studs to ZClips with two (2) 1/2 inch (13mm) type S-12 screws. Remove excess fireproofing from insides of J-Runners and E-Studs before installing liner boards.

3.6

C.

Cut liner boards 1 inch (25mm) less than distance from floor to structure above; erect vertically into floor and overhead J-Runners, and into jamb J-Runner or EStud. Where wall height exceeds maximum length of liner board, position board end joints within upper and lower 1/3 of height from floor to structure above; stagger joints in adjacent boards. Achieve tight fit at mating board ends.

D.

Cut C-H Studs not less than 3/8 inches (10mm) nor more than 1/2 inch (13mm) less than distance from floor to structure above. Fit first C-H Stud over leading edge of first liner board. Install remaining liner boards and C-H Studs. Do not attach C-H Studs to J-Runners.

H.

For walls above doors miter-cut J-Runners legs and position J-Runner horizontally to fit tightly between strut studs to serve as opening head. At each jamb extend JRunner upward into overhead J-Runner. Attach J-Runner webs to strut stud webs with 3/8 inch (10mm) Type S-12 screws spaced not more than 12 inch (305mm) oc, 2 inches (51mm) above opening head, and not more than 4 inches (102mm) from overhead J-Runner, using not less than 3 screws per jamb. Install C-H Studs horizontally at not less than 24 inches (610mm) o.c.; attach to each mitered jamb JRunner one (1) 3/8 inch (10mm) Type S-12 screw shaft side and one (1) floor side.

I.

Provide additional liner boards, gypsum shims and fillers at elevator door frames as necessary to maintain fire integrity of the tested labeled frame construction. Construct opening in conformance with frame manufacturer's fire test report; secure copy of fire test report from frame manufacturer and maintain on site for elevator inspector.

J.

Small openings: Frame openings with E-Studs or J-Runners at jambs; frame heads and sills with J-Runners. Attach head and sill J-Runners to jambs with two (2) 3/8 inch (10mm) Type S-12 screws on shaft side and one (1) on floor side.
