ti <br />ti <br />System No. HW-D-0077 <br />0 <br />3 <br />A2. Light Gauge Framing* -Vertical Deflection Ceiling Runner — As an alternate to the ceiling runners in Items 2A and 2A1, vertical deflection <br />ceiling runner to consist of galv steel channel with slotted vertical deflection clips mechanically fastened within runner. Slotted clips, provided <br />with step bushings, for permanent fastening of steel studs. Flanges sized to accommodate steel studs (Item 2B). Vertical deflection ceiling <br />runner installed perpendicular to direction of fluted steel deck and secured to valleys with steel masonry anchors, steel fasteners or welds <br />spaced 24 in. (610mm) OC before or after optional spray -applied fire resistive material is used. The use of welds to secure the ceiling runner <br />may only be used prior to the installation of the optional spray -applied material. <br />THE STEEL NETWORK INC — VertiTrack VTD250, VTD362, VTD400, VTD600 and VTD800 <br />A3. Light Gauge Framing* - Notched Ceiling Runner — As an alternate to the ceiling runners in Items 2A through 2A3, notched ceiling runners <br />to consist of C-shaped galv steel channel with notched return flanges sized to accommodate steel studs (Item 213). Notched ceiling runner <br />installed perpendicular to direction of fluted steel deck and secured to valleys with steel masonry anchors, steel fasteners or welds spaced 24 <br />in. (610mm) OC before or after optional spray -applied fire resistive material is used. The use of welds to secure the ceiling runner may only be <br />used prior to the installation of the optional spray -applied material. <br />OLMAR SUPPLY INC — Type SCR <br />B. Studs —Steel studs to be min 2-112 in. (64 mm) wide. Studs cut 1l2 to 314 in. (13 to 19 mm) less in length than assembly height with bottom <br />runner without attachment. When slotted ceiling runner (Item 2A1) is used, <br />nesting in and resting on floor runner and with top nesting in ceiling <br />steel studs secured to slotted ceiling runner with No. 8 by 112 in. (13 mm) long wafer head steel screws at midheight of slot on each side of <br />wall. Stud spacing not to exceed 24 in. (610 mm) OC. When vertical deflection ceiling runner (Item 2A2) is used, steel studs secured to slotted <br />vertical deflection clips, through the bushings, with steel screws at midheight of each slot. Stud spacing not to exceed 24 in. (610 mm) OC. <br />C. Gypsum Board* — Gypsum board installed to a min total thickness of 5/8 or 1-114 in. (16 or 32 mm) on each side of wall, for 1 or 2 hr fire <br />resistance rated walls, respectively. Wall to be constructed as specified in the individual U400 or V400 Series Design in the UL Fire <br />Resistance Directory, except that the gypsum board is cut to fit the contour of the steel floor units with a max 314 in. (19 mm) gap. The screws <br />attaching the gypsum board to the studs at the top of the first layer shall be located 4 in. (102 mm) from the steel floor unit valleys. The screws <br />attaching the second layer to the steel studs shall be installed into the studs 3-112 in. (89 mm) below the valleys of the steel floor units. The <br />hourly fire rating of the joint system is dependent on the hourly rating of the wall. <br />3. Fill, Void or Cavity Material* — Sealant — Max separation between bottom of floor and top of wall is 314 in. (19 mm). The joint system is designed <br />to accommodate a max 17 percent compression or extension from its installed width. Min 1-114 in. (32 mm) thickness of fill material flush with the <br />surface of the gypsum board for 2 hr fire rated systems or 518 in. (16 mm) thickness of fill material for 1 hr fire rated systems installed on each side <br />of the wall between the top of the gypsum board and the bottom of the steel floor or roof deck or the spray -applied fire resistive material on the <br />steel deck. <br />HILTI CONSTRUCTION CHEMICALS, DIV OF HILTI INC — CP606 Flexible Firestop Sealant <br />* Indicates such products shall bear the UL or cUL Certification Mark for jurisdictions employing the UL or cUL Certification (such as Canada), <br />respectively. <br />Reproduced by HILTI, Inc.
