• lag screws) are selected to meet applicable pull-out and shear design loads. Prior to installing the FLAT JACK® Roof Mount system, a site/roof layout drawing should be created to ensure the photovoltaic (PV) system is structurally adequate and meets the requirements of applicable building codes (IBC 2006 and ASCE 7-05). -
Page 16: Flat Jack® Mounting Configurations Vs
Selecting Mounting Configurations The maximum uplift load normal to the mounting surface depends on the location of the mounting bolts that secure the FLAT JACK® base to the roof. The following mounting bolt configurations are recommended: Configuration A: This configuration is for applications •... -
Page 17: Configuration B Description
Figure 4-1. Mounting Configuration A If adjustability is necessary, an additional fastener can be used anywhere along the slot. Configuration B Description In Configuration B, one fastener is used in the lower bolt hole, and another is used anywhere in the bolt slot to allow adjustability. -
Page 18: Lateral Load Considerations
(e.g., snow loading) in addition to the weight of the PV system. The lateral load, perpendicular to the FLAT JACK® stud, should not exceed 160 lbf (710 N). Figure 4-4 shows the direction of force in lateral loads. -
Page 19: Example Wind Load Calculation
4.5 Example Wind Load Calculation using ASCE 7-05 The TTi FLAT JACK® has been installed on a wide range of residential rooftops. It can be mounted properly with a wide variety of PV systems. NOTE: The following example is provided FOR INFOR- MATION ONLY, and should not be used in place of your own engineering calculations. - Page 20 F = 0.6 x Dead Weight of Structure + Wind Load This load is applied to the layout with various spacing options and compared with FLAT JACK® capacity configurations described in paragraph 4.3. With this design load, Configuration C could be used with a maximum spacing of 32".
