ost-tension, applied to industrial oors represents a revolutionin the Market, a new concept o quality and proessional

approach.

Techinfoor is the exclusive Distributor in Europe o the Post-tension System, called TENSIOPAV, developed within anInternational partnership with ORI Martin Group, with SLM- Siderurgica Latina Martin -, manuacturing Company o steel

unbounded strands and cables, and with TT M, a leader Firm inplanning and application o the Post-tension System on majorbuilding jobs such as bridges, aqueducts, Interports, etc.

TT M provides complete consultancy support, rom theplanning phase to supply o the Post-tension Hard ware(accessories, electronics, stressing jacks), to the fnal

tensioning phases. Such innovative Technology consists on

replacing the traditional armor (electro-sealed nest, metallicfbers, synthetic fbers, glass fbers, etc.) with unbounded,

greased and sheathed, drowned in the concrete steel strands,

then Post-tensioned with hydraulic stressing jacks.TENSIOPAV System is guaranteed: rom the initial engineeredplanning which inuences the eects o all operation, to the

typical techniques o the oundation, up to resistance against

the loads, both static and dynamic; everything is engineered

and designed, rom the thickness o the plate, to the strand

disposition and the additional armor, as well as the specifc

characteristics o the concrete.

The concrete mix design, the pre-qualifed recipe veriyingthe characteristics o the mix in the concrete trucks, and the

constant control techniques applied directly on the job site, will

create a mapping o the constructive whole process.

A oor fnalized with the TENSIOPAV System will thereoreresult scientifcally projected, punctually checked and guar-anteed with a 10 Years Posthumous Policy Insurancecovering replacement o partial or total work.

o concrete industrial surfaces

TENSIOPAV is the solution to the traditional problems o each

industrial oor: it is now possible to create oors without joints,

without cracks, without waving, wide monolithic suraces, with

reduced thickness, which provide high atness and drastic reduction

o maintenance costs.

TENSIOPAV proves to be perect or all implants which are build

to have high shelves, highly concentrated and dynamic loads,

systematic circulation o vehicles with low wheels, oors with resin

coverings, and in general or all the highly unctional and industrial

suraces.

> Post-tensioning applied to radiant suraces

TENSIOPAV System is the perect solution where a heated oor

is planned: the post-compression o the concrete, in act, creates

a resistance to revealed cracks created by the continuous cycle o

cooling and heating o the radiant foor.

The linear expansions inducted by the thermal variations are

limited, so a perect efciency o the whole structure in terms o

global resistance and perormance is actually provided.

TENSIOPAV can provide absolute application exibility versus anytraditional system: irregular geometric shapes (triangles, trapezes,

narrow rectangles, etc.) and/or outdoor oors with complex con-

structive parameters can be built at ease.

The building process

Engineered PlanningThe concrete Post-Tensioned plate is dimensioned with anaccurate engineered planning o each single detail, beginning rom

the position o the steel strands, the evaluation o the distancebetween nest strands, the position o a low armor at the bottom

o the punctual and distributed loads, up to the organization and

the sequence o the concrete placements with respect to the

specifc requirements.

Verifcation and preparation o the oundationThe careul and accurate preparation o the oundation is a un-

damental must, when the use o the Post-tension System isplanned: it is mandatory to veriy the carrying ability, the planarity,

the degree o compact resistance and homogeneity o the ounda-

tion; a double layer o polyethylene is put on ground in order tocreate a layer that isolates the concrete plate rom the ground,

and to reduce attrition during Post-Tensioning operations.

Custom cut and position o the steel strandsPredisposition o the closing procedure with the easy-system,position o the slow armors around the pillarsand to the fxed

points o the structure, carrying out strand distribution, cut o the

strands and their position according to the original planning.

Throw and punctual control o the building process

During the distribution on ground, the strand nest is set on distancechairs to the appropriate level comparing to the thickness o

the plate. During the concrete placement, an integrated control

o the concrete and its technical characteristics is set in place

by collecting the samples on which a certifed Laboratory will do

the proper tests, and rom which it will extrapolate the minimum

tensioning values.

In order to enable the correct access o the stressing jacks or the

ollowing tensioning phases, a ree band is set up two sides o

the perimeter o the structure; this perimeter will be armed and

subsequently covered with concrete.

Partial and fnal TensioningThe frst stressing, or partial tension, will be applied usually ater

24 hours with a special hydraulic stressing jack, in order to oppose

the plastic micro-cracks o the concrete.

As soon as the ft resistance o concrete will be reached (usually

ater 72 hours), concrete will be fnally post-tensioned, so that this

will coner the plate the carrying ability required by the project,

and the construction joints will be compressing one against the

other the linked lots.

Superfcial fnish and closing o the perimeter bandAs soon as Post-tension System is applied, the ree perimeterband will be covered with concrete, and chemical surace

hardening fnishes will be applied.P

Engineered Planning

> Floor Engineering

The planning o the steel strand nest, with the evaluation

o the relative distance, is a mandatory step into the

realization o the work. It assures the correct evaluation

o all the constructive parameters and it guarantees that

the work is fnalized according to the engineering criteria

related to the Post-tension Technology.TT M always will guarantee an immediate answer tothe application requirements o the Customer, assuring

a exible and reliable approach during calculation, sizing

and planning o the TENSIOPAV system.

Last generation sotware application, allows to develop

the calculations in perect relationship to the loads that

the oor will have to bear, based on the use destination

o the property, and to where the structural loads may be

distributed in particular points o the structure.

The project comprehends constructive details, passive

armors location and slow armors placement along andaround the pillars.

Preparation o the oundation

> Verifcations o the oundation material char-

acteristics and o ground conditions, through

plate tests

The Load Test on static plate with consequent calculation

o the Deormation Degree, is necessary to veriy that the

oundation will support perormance requirements imposed by

the specifcation o the engineered plan.

The resistance control Test on the job site, in correspondence

o the oundation, is in act o undamental importance in order

to be able to guarantee the minimum requirements o ground

mechanical resistance and stability against the loads that will

cover it. To veriy then the homogeneity degree o the ground

oundation, the device LIGHT FALLING will be used, and then

the WEIGHT DEFLECTOMETER as below specifed.

The 300 mms diameter and 20 mms thick galvanized steel plate,

can be considered sti as per the calculation targets o the plan

submitted to the test: the load assumes orm o a damped hit,

and the test is said to be dynamic.

The test LFWD is a unctional beta methodology: efcient, rapid

and representative.

It will be necessary to compare results o the deormation orm

versus the dynamic Evd values, and with the middle values Md

o the test o load statics.

> Barrier to Moist and double slide layer

The sheet o polyethylene, in double layer, is put above the

compacted oundation material, and it develops the double

unction o barrier to the moist, and o layer o slide that

allows the Post-Tensioned plate to stir without rigid ties in

the tensioning phase or during longitudinal movements.

In act, as quoted by the norm UNI 11146, the sheet o

polyethylene in double layer introduces the lowest attrition

coefcient among the plate and the oundation and it resultsideal or the post-tensioned applications.

reparation o the oundation represents the frst operational and undamental step into the construction

o a Post-Tensionedsurace using theTENSIOPAVSystem.The interventions particularly to be taken care o, are the ones related to the ollowings essential

requirements:Compact pressure in order to avoid yeldings when the oor is in exercise phase;

Leveling, in order to allow the ree slide o the plate.

It results thereore undamental, to perorm technical surveys ocusing on the Deormation Degree o

the oundation, applying tests on the plate, both static and dynamic.P

Easy-system Closing Procedure

> Assemblage o the perimetral closing bends

The easy-system is projected or this particular job, and is

constituted o two symmetrical metal stirrup and by one closing

wooden band.

The upper stirrup closes on the wooden band and fxes the

closing in a rigid way so that it is possible to regulate the plate

thickness determined by the project requirements.

On the wooden band are subsequently fxed the active heads, or

the heads rom which the entrance stressing jacks are set up or

the ollowing phases o partial and total tensioning.

he closing procedure o the assembly plates

has been optimized with the defnition o

the Easy-system Closing Procedure, that

guarantees rapidity and precision while in thephase o concrete placement preparation: the

ollowing phases result rapid and secure and

the construction joints are properly sealed

and proteceted.T


9/16

Strands

> Cut o the strands

The strand goes out rom the wheel along a metallic line, and once

fxed the desired length, the strand is cut to measure coherent

with the project.

The repeated operation creates the set o strand necessary to the

job in an easy, sae and ast way.

> Carrying out on the job site the strand

placement

The carrying out o the steel strands takes place on the job

site thanks to a system patented by TTM, our Partner inPost-tensioning: the spool is loaded on a base with

a particular cone connected to a pushing system controlled

by an hydraulic device. The particular mechanism allows

to develop the spool in simple way and in ull saety,

paying particular attention to the ree end o the spool,

that can result dangerous even i engaged into the conic

base.

The spool is pushed out beginning rom the cone, which

controls the carrying out process and allows the correct

placement o the long strands all over the oor.

Strand nest Placement and Heads fxing

> Installation o the wedges in the headings and bindingo the intersections o the strand nest

The heads anchorage is done fxing the wedges in the heads at the end o

the strand, through the ollowing operations:

cut o PVC cover, approximately or 5 cms, rom the end o the strand;

positioning o the heads on the strand and insertion o the wedge in

order to assure its fxing; this operation is necessary in order to fx, in

a total sae environment, the passive head which, drowned into the

concrete, will be highly solicited during the Post-tension action.

The consequent consists o putting to strands on a network design,

distancing them correctly in both directions, and sealing each single

intersection in a way that can guarantee the correct positioning ater the

concrete trucks have delivered the cements.


11/16

Additional passive armors

> Installation o passive additional non pre-tensioned

armors

In order to better distribute loads along the perimeter dedicated to the

heads, additional metal bars are put along the closing ends, so active

heads will not mode while concrete will be stressed.

To absorb tensions in elevation and close to the pillars, additional armors

are positioned as per engineered planning.

The vertical structures englobed in the concrete placement throws

(pillars, grits, walls,etc) will become isolated with compressed but thick

materialproven to to guarantee the slide o the plates while in post-

tensioning phase.


12/16

Laser Screed-based concrete Placement

> Concrete Placement on the job site

The Concrete Placement is usually done with Laser Screed

technology, the laser controlled Machine with vibrating control

that guarantees highly compact pressure o the concrete, together

with a atness degree: the vibro-placement o the upper part o

the concrete allows air molecules to evaporate, so the oor will

be ree o micro-cracks and nests.

Besides that, the Laser-Screed sensitively reduces execution

times, allows to compact suraces much better than with the

traditional manual placement.

Contextually to the concrete placement, the needle vibratingoperations take place, while the distance chairs are set up on the

crossing, ollowing project specifcations.


13/16

Punctual control o the concrete

> Punctual control o the concrete

The technological building process o the TENSIOPAV System includesalso a pre-qualifcation o the concrete implant, in order to make sure

that the optimal prescriptions o the mix-design and the punctual control

o the mixture o urnished concrete are guaranteed: on the job site

specifc tests are perormed according to normative, and according to

the Pavical requirements to comply to the project applications in terms

o resistance and composition that the concrete must guarantee or a

proper application o the Post-tension System.The samples collected in square dice are submitted to crushing in

certifed laboratories so that the resistance matured rom the concreteater 24 and 72 hours are defned and inspected and thereore, once

extrapolated, the relative pressure levels will be applied rom the

stressing jacks during post-tensioning operations, both partial and fnal.


14/16

Partial and fnal Tensioning operations

The wooden band is removed the ollowing day ater the

concrete placement, only i concrete has reached the correct

strength in order not to be damaged.Cleaning o the anchorage hollow takes place, then it is

important that the stressing jack does not have any obstacle,

and that the wedges are perectly installed in the headings.

Integrity o the concrete is checked, both along vertical and

the longitudinal parts o the surace, and that there are not

cracks, or nest eects, or micro-caves.

A deep check is dedicated that strands are perpendicular to

the anchorages and that the anchorages parallel to the ace o

concrete, then the stressing jack is set or operation.

The stressing jack has a designed device that exactly covers

the taking o the strand in the exact end point o the concreteplacement.

Introducing a small pressure on the jack, it is able to com-

pensate, partially or totally, the traction stress nduced by the

spontaneous withdrawal o the concrete.

Strand Extension

Piston excursion

Fixing wedges are perectly positioned to avoid their separation

during the positioning o the stressing jack.A specialized operator o TTM is there to properly apply the

Post-tensionprocedures, coherent with the recommendations

on saety operations defned by the same TTM.

Ater the Tensioning operations, actual extensions o the

strands are noticed, comparing them with the theorical onesexpected by the project requirements, and veriying the

perect equipment efciency.
