SYNOPSIS OF CHANGES IN 15C STATE OF FLORIDA 1. I-BEAM CLAMP THAT PIVOTS-TOP OF FRAME ONLY The State of Florida now requires that the strap be attached to the I-beam by a beam clamp that has a swivel attachment. This eliminates the sharp edge of the frame cutting into the strap and the possibility of stressing one edge of the strap by misaligning the anchor with the attachment point to the I-beam. 2. GALVANIZED STRAPS.60 OUNCES EACH SIDE OR NOMINAL G115 Florida now requires that all strapping have extra galvanization to protect from the elements.All strapping must be marked with the"G115"coating,and Tie Down strap will indicate"QUAD COAT G-120." The ASTM 3953-91 must still be referenced on the strap to indicate conformity to the HUD Code, and the G115 will indicate the extra coating. All strap must be marked every 12"to 15". 3. ALL ANCHORS GALVANIZED All ground anchors,concrete anchors,patio anchors,etc.-must be hot dip galvanized. 4. MINIMUM STABILIZER PLATES 180 SQUARE INCHES,GALVANIZED The small 12"stabilizer plate is no longer certified in Florida. All stabilizer plates underthe new regulations must have a minimum 180 square inches of surface and must be galvanized.Tie Down manufactures the 17.5 inch plate that is galvanized to meet Florida requirements. 5. RADIUS CLIP PROTECTION The State of Florida no longer allows the strap to wrap the I-beam.Because strap must be protected from contact with sharp edges,the strap must now be attached to the I-beam by means of a swivel connector with a radius clip(rolled edge).The strap must also be factory attached to the connecting swivel bracket Field attached crimp seals are no longer allowed for use on straps used to attach to frame connectors or hooks. 6. SIDEWALL VERTICAUFRAME TIES 514"O/C The maximum distance between sidewall vertical/frame ties is now 5'4"on center. 7. CENTERLINE TIES WITHIN TWO FEET EACH END Every new and used multi-section home must include a centerline anchor installed within two feet of each end of each centerline(the home manufacturer may require additional anchors. 8A.LONGITUDINAL ANCHORS,TWO PER I-BEAM PER END As part of the new rules,every home must be installed with protection from wind loads on the end of the home. The Florida rules require two anchors per I-beam per end. This means that a single section will require four longitudinal anchors per end for a total of eight for the home. A double section home will require eight anchors per end for a total of sixteen per home. As with all ground anchors,these must be hot dip galvanized and in stalled with a galvanized stabilizer plate.Torque probe is required on longitudinal anchors. 8B.LONGITUDINAL STABILIZER DEVICES As an alternate to installing longitudinal anchors and stabilizer plates,the installer may use other longitudinal stabilizing devices approved by the state,including Tie Dow n's USD(Longitudinal Stabilization Device). The use of two LzSD systems on a single section home replaces all eight longitudinal anchors/stabilizer plates.Four LzSD systems on a double section home,replaces sixteen anchors/stabilizers/frame tie connectors. 9. SOIL TEST While the soil test probe is not specifically addressed by 15C,the installer is required to A)test and record the torque readings and install the correct ground anchor(48"or 60")or B)use a 60"galvanized anchor with stabilizer plate where no testing is recorded. 10.INSTALLER PLAN FOR 1,000 PSF SOIL The installer must submit a foundation plan(as to the load bearing capacity of the soil) to the building department at the time of application for the building permit If the soil is not tested with a penetrometer,then the plan submitted must assume 1000 PSF soil.The installer is required to use a pocket penetrometer to determine the PSF. NOTE:1000 PSF soil most commonly requires Type 11,60"anchors. 11. MINIMUM HEIGHT 18 INCHES The minimum pier height at the lowest part of the home shall be 18". This distance is measured from the bottom of the frame(1-beam)to the ground or slab.Note:3/4 of the home must be at the minimum 1811,the balance of the home cannot be lower than 12". 12. GROUND ANCHORS/FLORIDA ONLY For purposes of installation of manufactured/mobile homes in the State of Florida,there will be two soil classifications: Type 1: This soil is described as"loose to medium dense sands,firm to stiff clays&silts,alluvial fill." It has a Blow Count(per ASTM D1586)of 18 to 23,and a reading on the Torque Probe of 276 to 350 inch pounds. The Working load for an anchor in Type I soil is 3,150 lbs.and the Ultimate load is 4,725 lbs. A 48"anchor is to be used in 4A soil classifications. Type II: This soil is"very loose to medium dense sands,firm to stiff clays and silts,alluvial fill." The Blow Count for Type 11 soil is 12 to 17,and the torque reading 175 to 275 inch pounds. The Working load is described_ as 4,000 lbs.and the Ultimate load is 6,000 lbs.A 60"anchor must be used in 4B soil classifications. - N TIE ! • WN ENGINEERING - 255 Villanova Drive SW Atlanta, GA 30336O www.tiedown.com I I1II 4I4 II 10 p O
