Ischebeck Titan | Method statement | Titan support system May 2008Standard erectionprocedure1. Set the jack nuts in the approximateposition to give the correct jack extension.Then insert the jack into the ends of thelegs so that the nut engages with theretaining clip2. Place the legs, complete with jacks, atapproximately the required leg centres onthe ground, introduce a ledger frame of thecorrect length between them and securethis in position. It will be found that theoperation of tightening the ‘T’ bolts will befacilitated if the middle‘T’ bolt is left until last.It may be found necessary to completelyunscrew wing nuts before attempting tolocate. When the line on the end of thestem is in line with the slot in the outer leg,the ‘T’ bolt has been positioned correctly.3. Vertical ledger frames are now fixed to thelegs in a similar manner to paragraph 2.4. A further two legs are assembled in asimilar manner to paragraph 2. The twoassemblies may now be raised until thelegs are vertical and the exposed ends ofthe ledger frames connected to the legs toform a four leg tower.Page 10 of 27

Ischebeck Titan | Method statement | Titan support system May 20085. Ledger frames can be hung off any face ofthis tower and the erection continued untilthe desired falsework area has beenachieved.6. Propriety decking or standard scaffoldboards can be used to form a suitablework deck for fixing aluminium formworkbeams. If boards are used intermediatetransoms will be required and theseshould be positioned at 1.5m maximumcentres to suit the permissible board span.7. Titan quick release handrail frames shouldalso be used for edge protection aroundthe work area. Scaffold tube handrails andposts can also be fixed to the system ifrequired.Page 11 of 27

Ischebeck Titan | Method statement | Titan support system May 20088. If the falsework requires more than one liftof legs and ledger frames then this will beerected off the work deck as describedpreviously. The next lift of legs are invertedand fixed to the first lift by means of 2 No.Titan fast connector brackets or 4 No. M12x 35 bolts and nuts. Ledger frames to befixed to the legs as previously described.A work deck will be required at the higherledger frame level to provide access for thefixing of formwork beams.An alternative to the above is to assemblea tower as described in paragraphs 1-4and then crane handle this tower intoposition and bolt headplates together asshown.Any lacing or bracing that may be requiredshould be fixed before the working load isapplied.9. Only recognised Titan clamps are to beused for the fixing of Titan beams.10. Primary beams should be placedcentrally on the headplate of the leg orjack and fixed by means of 2 No.Speedthread Titan clamps or Titan ‘T’bolts and nuts.11. Secondary beams are then placed on topof the primary beams at predeterminedcentres and fixed by the Titan clamp ateach intersection with the primary beam.Plywood is then fixed to the secondarybeam by means of suitable nails/screws atthe required centres.Page 12 of 27

Ischebeck Titan | Method statement | Titan support system May 2008Titan falseworkMethod of Dismantling1. Begin dismantling operation by loweringthe jacks. Titan spanners to be used.2 Release secondary members by undoingthe Speedthread clamp and passing eachbeam to the ground from an intermediateworking platform.3. Repeat process 2 for primary deckingmembers.4. Stripping of Titan falsework should beginby releasing one end of one ledger frameat all three locations and repeat thisprocedure for the adjacent Titan ledgerframe which runs off at right angles.5. The above procedure will then release aleg, leaving two ledger frames ‘hanging’from other legs.6. The ledger frames should now beremoved by following process 4.7. Continue repeating processes 4 and 5until all falsework is removed.8. On falsework structures greater than oneleg in height, all works as previouslydescribed should be carried out fromsafe, temporary working platforms aspreviously recommended.Safety checklistThe following checklist should be adhered to priorto the placement of concrete:-1. Ensure plumbness of legs.2. Ensure that all spring loaded wing nuts are tighton ledger frames (over-exposed thread on ‘T’bolt indicates otherwise).3. Ensure that base jack extensions are withindesign parameters.4. Ensure that jack nut is properly located in leg(Retainer clip securely fixed).5. Ensure that the jack base plate/headplatemaintains positive friction against floor slab.6. Ensure that the size, number and location ofledger frames are as per design drawings.7. If bolting legs together vertically and/or usingextension pieces, ensure that a positive, rigidconnection is maintained by means of 4 No.M12 x 35 nuts & bolts or 2 No. Titan connectorbrackets.8. If using jacks at the top of the falsework, ensureitems 3 and 4 above are followed and that 2 No.Titan clamps/‘T’ bolts are used to locate jackssecurely to underside of primary beams.9. Ensure that primary beam spans are no greaterthan those shown in design drawings.10. Ensure spacing and span of secondary beamsare no greater than those shown in designdrawings.11. Ensure all/any damaged parts are removed andreplaced immediately.12. Ensure the proper safety procedures areadopted to facilitate the above items incompliance with construction and health andsafety working regulations.Page 16 of 27

Ischebeck Titan | Method statement | Titan support system May 2008Titan tableforms (tables)IntroductionThe following identifies the componentsrequired and their proper use with a step bystep procedure for stripping, flying andlanding a Titan tableform (table).Instructions are provided for standard tables.GeneralFlying and Stripping EquipmentTrolleys/castors are used in the stripping and flyingprocedure of a Titan table.A minimum of 4 No. trolleys/castors are used forthe movement of the table. 2 No. trolleys/castorsare used adjacent to the second row of legs in fromthe front of the table. These positions may varydepending on size and weight of table.It is essential that these procedures are fullyunderstood before the equipment is used. Itis, therefore, recommended that allpersonnel using the equipment on the firstoccasion should be supervised by acompetent person.There may be occasions when it isnecessary for operatives to work adjacent tounguarded slab edges. In all such casesoperatives should wear suitable anchoredsafety harnesses. In addition, otherpersonnel should be made aware of suchshort duration hazards.Particular attention should be paid by sitemanagement to ensure that crane signallingsystems comply with ruling regulations andthat laid down procedures are fullyunderstood and complied with.Loose materials or equipment must not betransported on tables during moving andflying operations.At no time during the operations is itnecessary or desirable to exert undue force,either manually or through the equipment.Page 17 of 27

Ischebeck Titan | Method statement | Titan support system May 2008Titan tableforms (tables)Stripping and flying procedureBefore any stripping takes place, all obstructions to the safe movement of the table must be removed.1. Break bond between slab and decking by turning collars on jacks thus creating first stripping action.2. Having wound about 100mm off each jack, locate trolleys or castors as previously instructed.3. With weight of table now being carried by the trolleys or castors, retract remaining jacks to provide sufficient clearance.The table is now in the lowered position.Page 18 of 27

Ischebeck Titan | Method statement | Titan support system May 2008MovingTo enable tables to be removed horizontally it is recommended that electric chain hoists are used to allow automaticcompensation of lifting chains.4. After removing slab edge protection, the table should be pushed until the first two legs are clear of the slab,allowing fixing of chains at predetermined lifting points that suit the balance of the table.If trolleys are used the front pair are removed once chains are connected.5. Continue pushing table (helped now by pulling action of crane) until the third line of legs are visible outside theline of the slab and repeat as above. If used, remove rear trolleys once chains are fixed.Page 19 of 27

Ischebeck Titan | Method statement | Titan support system May 2008Titan tableforms (tables)6. The table is now ready to be completely cleared from the slab and lifted to the next bay or floor above.7. It is suggested at this stage that, if required, the contractor’s props for re-propping are installed at the necessarypositions.Page 20 of 27

Ischebeck Titan | Method statement | Titan support system May 2008Re-FixingTables should be set down at approximately the position required when pouring concrete.8. Jacks which are retracted should be wound down so as to take the weight of the table whilst the castors are removedfrom the other legs.Final level by site engineer9. Once castors (If used) are removed, the table is free to be levelled into final pouring position by site engineers.Process repeatsN.B.All narrow width tables should be stabilised against overturning from either wind forces or horizontal loading due toconstruction loads.Where operatives are required to lean over the edges of the slab, a suitable harness must be worn and appropriately fixed.Page 21 of 27

Ischebeck Titan | Method statement | Titan support system May 2008Titan table movement using Titan trolleys• Titan tables must be struck beforepositioning trolleys so that the table is nolonger carrying concrete load.• Trolley must be in proper working condition.• Trolley must be used for its proper designpurpose only.• A minimum of 4 No. Titan trolleys to beused on Titan tables with 6 legs or more.• Trolleys to be positioned as close to theTitan legs as possible.• Safe Working Load of 1000kg. must not beexceeded.• Trolleys must be raised or lowered insequence to prevent overloading.• Ensure floor slab is clear of debris.• Table to be raised at least 50mm clear offloor slab.• Care must be taken when working close toslab edge.• Trolleys must be removed before flyingtables.• Trolleys must be inspected at least once ayear by a suitably qualified person.• If in doubt about trolley positions contactthe Ischebeck Titan Design Office.• Health and Safety requirements must befollowed at all times.Page 22 of 27

Ischebeck Titan | Method statement | Titan support system May 2008‘C’ hookNote:Self weight of table + self weight of ‘C’ hook must not exceed crane capacity.Test for centre of gravity of tables at ground level and mark lifting plate positions of each table size on the top boom of the‘C’ hook.Stage 1Lower table approximately 200mmStage 2Remove slab edge protection.If required, remove table handrails and posts.Operatives to wear suitable safety harness.Page 23 of 27
