SigmaFire Installation Manual, rev. F - Clayton Industries

Section II - General InformationPerform stress calculations for the steel structureto confirm it has adequate rigidity to minimize baseplatedistortion and vibration during operation. Clayton recommendsincorporating vibration isolation on this typeof installation.2.2.2 Equipment AnchoringTo properly secure the equipment base frames tothe equipment maintenance pads and foundation, properanchor bolts are required. The anchor bolt diameter mustbe fully sized to the anchor bolt holes in Clayton’sequipment base frame. For required bolt sizes, see theplan installation drawings for the specific Claytonequipment. The anchor bolt length extending above thefoundation should equal the total height of all shimmingand leveling devices, 3/4–1 1/2 inch (2–4 cm) groutfiller for leveling, the equipment base frame thickness,washer set, anchor bolt nut, and an additional 1/2 inch(1.5 cm) above anchor bolt nut (See Figure 2-1.).The proper anchor bolt length and its embeddeddepth must meet all static and dynamic loading from theoperation of the equipment, wind loading, and seismicloading.NUTWASHER SETEQUIPMENTBASE FRAME*SHIM/LEVELINGGROUT FILLERFOUNDATIONEQUIPMENTMAINTENANCEPADANCHOR BOLT1/2 in.(1.5 cm)* SHIMS MUST BE C-SIZE, OR LARGER, FORPUMP SKIDS AND E-SIZE, OR LARGER, FORGENERATOR AND WATER SKID FRAMES.Figure 2-1 Anchor bolt installationCAUTIONFailure to adequately support Clayton’s equipment can lead to excessive vibration,which is detrimental to Clayton’s product and component life cycle, especially electricalcomponents.2.2.3 GroutingMake sure to grout the entire equipment base frame before making any additional connections toyour Clayton equipment. Grouting the equipment base frame to the foundation provides a good and sturdyunion between them. Grout is a concrete-type material that is used to fill the gap between the equipmentbase frame and the foundation. The grout increases the mass of the base to help reduce equipment vibration,which is fundamental to product life. In addition, the grout will fill any voids or imperfections in the foundationsurface to increase proper equipment support. When the grout hardens, the equipment base frame andthe foundation becomes one solid unit to support the equipment.04/21/2015 2-3 Sect02_Genrl-SF_q.fm
