The MillsTour shoring system can be used to erect self-supporting shoring towers, in runs or blocks, to transmit

vertical loads to the ground.

For many years, Mills Tour has been the French market leaderfor civil engineering and public works.

This high performance shoring system has a telescopic level,modular units and lightweight components.

Mills Tour : modular and high performance

The Mills Tour shoring systemcomprises prefabricated modular

components that fit together and lock without using couplersor bolts.

The Mills Tour shoring system isconstructed so that that each vertical face, including the telescopiclevel, is fully braced over thewhole height.

The Mills Tour range: - MT 65 and MT 100.- 1.00 m, 1.60 m and 2.20 m spacing.- The MT 65 can support up to 6.5 tonnes at 1.00 m and 1.60 m spacing and up to 6 tonnes at 2.20 m spacing.- The MT 100 can support up to 10 tonnes at 1.00 m and 1.60 m spacing.- Basic levels are 1.20 m high.- Telescopic levels can be adjusted from 0.15 m to 1.05 m insteps of 15 cm.The tower height can be finely adjusted using screw jacks at thebottom and adjustable heads at the top with a travel of 20 cm.

Mills designs, fabricates and distributes itsown shoring systems.

> Frame strengthThe strength of each frame undera horizontal force H was determinedby testing.It is:- 4.5 kN for 1.00 m spacing.- 6 kN for 1.60 m spacing.- 6.75 kN for 2.20 m spacing (half theultimate load limit).

> Base ledger strengthThe maximum load on the scaffold planks resting on thebase ledgers is given in the following table in kg/m².

> Maximum load onstandardsThe maximum load on each standard is:- MT65 at 1.00 and 1.60 m spacing:

6.5 t- MT65 at 2.20 m spacing:

6 t - MT100 at 1.00 and 1.60 m spacing:

10 t

These loads are based on officialtests carried out according to NFP 93-550. The towers are testedwith the screw jacks and heads fullyextended and with a horizontal loadat the head of 2% of the verticalload.The maximum operating load ishalf the ultimate load limit.

> StabilityThe tower must be stabilisedagainst wind loads, in particularduring assembling and dismantling.In the absence of special calculations,it is advisable to limit the height ofthe tower to 4 times the smallerdimension of the base.For taller structures, the towersshould be connected together oranchored to the structure to ensure stability in all directions. The horizontal braces are usuallyfitted every 4 levels or wherethere are connections betweentowers.

Extension bars30 cm extension bars are used toincrease the number of standardsto support heavy loads.The bars do not provide any windbracing in themselves. This is pro-vided by the frames.In practice, there should not bemore than 4 standards braced by aframe per level.

Recommendations for assembly> INSPECTION OFTHE EQUIPMENTBefore starting to erect the scaffolding- Check that the scaffolding is in goodcondition- Do not use any components thatare suspect (parts that are bent,squashed, loose, etc)- For towers, only use parts that are made by Mills. Do not use components made by different manufacturers.

> ENSURE COLLECTIVE SAFETYWhen designing how the shoring andformwork will be assembled anddismantled, attention should be paidto collective protection. If it is notpossible to ensure complete or partial collective protection, workers should have individual fall-arrest equipment.

> RECOMMENDATIONSWhen the shoring has been assembled, a formal acceptance report should be issued.

> REMOVING SHORINGThe support for the building structureshould be removed by lowering theadjustable heads to avoid destabilisingthe towers. All the heads should beunscrewed together to prevent theload being taken by heads that havenot yet been unscrewed.

> FORMWORKThe formwork calculations shouldtake account of load distribution. If abeam bears, for example, on 3 points,the load will not be distributed ac-cording to the simple geometric ar-rangement.

> STABILITY DURING ASSEMBLYThe stability of the shoring must bechecked while it is being assembledand dismantled and just before pou-ring, when the shoring acts as a sailand there is no concrete to act as ballast.

> LOAD DISTRIBUTION - BEARING SURFACE

Bearing on concrete slabIn general, a tower does not requireany particular preparation when itbears on a concrete slab. If the surface is uneven, wooden planksshould be used between the baseplates and the concrete.It may be necessary to provide shoring under the lower tiers if theyare unable to take the vertical load.Bearing on earthOn earth, the load must be distributed appropriately, dependingon the nature of the ground and theload.Differential settlementThe four base plates must bear onthe same type of surface so that

the settlement under each plate isidentical.

If this is not possible, for example, iftwo base plates bear on a concreteslab and two bear on earth, the loadon the base plates on the earthmust be spread to minimise settlement.

Excessively highstack of baulks

Bearing over a gutter

Bearing on hollow block

NB: The scaffolding must not bear on manhole covers, drain covers or on ground with unknown bearing capacity.In these particular cases, either change the location of the

scaffolding or increase the load spreading after taking expert advice.

VerificationIt is important to check thatF < P x S

F = downward force on standard. p = ground bearing capacity.S = bearing surface area.

If this is not case, the bearing areashould be increased by using an additional support. In practice, wooden sole boards orbaulks are often used for load spreading.The calculations should assume thatthe load is spread in a cone with anaperture angle of 90°.

If the ground bearing pressure is stilltoo high, baulks can be used in a stack.

a = width of the base plate A = 2 T + a S = A2

The baulks are frequently largerthan the load spreading cone. If the baulk is larger than “a” in anydirection, the dimension can still beused for calculating the bearing areaprovided that the dimension is lessthan or equal to L max whereL max = a + 3 T

For the stabilityof the shoring,particular attention must be paid to thetype of groundand its strength.
