  4. 4. 4Shear Load ConnectorsStandard Isolan systems, comprising rigidCFC-free polystyrene insulation and stainlesssteel shear reinforcement, suit most depths ofcantilever and simply supported balconies.The various systems allow the transfer of allloads in structural concrete i.e. moment, shear,compression and tension, and are suitable forstraight runs and both internal and externalcorners.System BenefitsAncon Isolan connectors use conventionalreinforcing bars to provide the tension andcompression reinforcement. When comparedto systems where this reinforcement is anintegral component, the Ancon Isolan solutioncan provide substantial cost savings andsimplify specification, scheduling,transportation, handling and installation.U-ValueThe Isolan system has a typical U-value of0.3 W/m2K.Curved or Stepped BalconiesSpecial configurations can be manufactured tosuit specific project requirements includingcurved or stepped balconies.Precast BalconiesIn addition to balconies cast in-situ, AnconIsolan systems can be used in precastbalconies. For such applications, tension andcompression bars must be scheduled andinstalled at the time of casting. Please contactAncon for more information.ANCON ISOLAN INSULATEDCONNECTORSIn applications such as balconies, whereconcrete slabs pass through the buildingenvelope, a cold bridge is created that canresult in significant heat loss.The Ancon Isolan system is a structuralcomponent used to join external concretebalconies to internal concrete floor slabs. Itprovides continuity to both the reinforcementand the thermal insulation of the wallprotecting the building against the effects ofcold bridging.Isolan®Insulated Balcony Connectors4RailISO-ElementTubeShear Reinforcement‘PRODUCTS FOR STRUCTURALCONCRETE’ DIVISIONAncon provides a dedicated service to theconcrete sector.

  7. 7. Tel: +44 (0) 114 275 5224 Web: COMPONENTSISO-ElementThe ISO-Element is 60mm thick, CFC-free,rigid white polystyrene insulation in a standardlength of 750mm. It is available in five heights(160, 180, 200, 220 and 240mm) to suitdifferent depths of balcony.Shear ReinforcementThe shear reinforcement is duplex stainlesssteel grade 1.4462 and is available in threediameters (6, 8 and 10mm) as standard. Inaddition to the standard systems, thisreinforcement can be bent into other requiredshapes outside the polystyrene insulationelement.TubesPolypropylene tubes with a 27mm internaldiameter are located at pre-determinedpositions in the ISO-Element to allow for thepassage of tension and compressionreinforcing bars.RailA high density polyethylene rail is located onthe top edge of the ISO-Element to protect theinsulation.Tension/Compression Reinforcement(supplied by others)Reinforcement used for tension andcompression bars to be grade 500B toBS4449: 2005 and supplied by others.Fire ProtectionThe Isolan system offers fire resistance to DIN4102: Fire behaviour of building materials andcomponents. Fire protection can be providedby adding Duripanel fire resistant strips to thebase or to the top and base of the ISO-Element.The strips are available in 18, 28 or 36mmthickness providing 30, 60 or 90 minute fireresistance respectively. Examples of how thesestrips are referenced are 1R30 for a 30 minutestrip fixed to the base and 2R90 for a 90 minutestrip fixed to the top and base. When specifyingand ordering, these references should beadded as a suffix to the Isolan system (seepage 8), for example 4MV6-200-5Ø12T/5Ø16C-1R60. The polyethylene rail is omittedfrom the ISO Element if these strips areemployed to the top.

  8. 8. SPECIFICATION GUIDANCEDesign InformationThe graphs on pages 10 to 14 are used toselect the most appropriate Isolan element,and the diameters of the shear, tension andcompression reinforcement.Example calculations are provided on thefollowing page. Consideration should be givento horizontal forces on parapets and localconcentrated load checks, these are notincluded in the examples.The graphs provide the design resistance(ultimate limit state) values for the shear VRdand moment MRd.The Isolan element design is based on normalstructural calculations. The calculations arebased on the following material properties.Concrete: C25/30 (cylinder/cubecompressive strengths)= 30N/mm2Reinforcement: Shear reinforcement material,duplex stainless bardesignation 1.4462BS6744, Grade 500Re or Rp0.2 ≥ 500N/mm2Rm ≥ 550N/mm2Tension and compressionreinforcement, BS4449,Grade 500BRe ≥ 500N/mm2Rm ≥ 540N/mm2The partial load factors used in the examples are:Dead load (persistent) = 1.35Imposed load (quasi) = 1.50How to Use The GraphsMV Elements1. The graph for the height of the Isolanelement that corresponds to balcony slabthickness is selected.2. The design shear capacity required (unit:kN per linear metre) is plotted on thehorizontal axis of the graph and a verticalline drawn. From this, the relevant Isolanelement type (i.e. 2MV6, 4MV6, 4MV8 or4MV10) is selected.3. The bending moment capacity required(unit: kNm per linear metre) is plotted onthe vertical axis of the graph and ahorizontal line drawn.4. The intersection between the vertical linecorresponding to the design shear capacityand the horizontal line corresponding to thedesign moment capacity determines therespective diameters of the tension andcompression reinforcement e.g. Ø12T/Ø16C.The first number refers to tension and thesecond to compression reinforcement. Referto the drawings on page 10 for the number ofbars required.V Elements1. The balcony slab thickness is selected onthe horizontal axis of the graph and avertical line drawn.2. The design shear capacity required (unit: kNper linear metre) is plotted on the vertical axisof the graph and a horizontal line drawn.3. The intersection between the vertical linecorresponding to the balcony slab thicknessand the horizontal line corresponding to thedesign shear capacity determines the Isolanelement type and diameter/number ofcompression bars.FD Elements1. The concrete thickness is selected on thehorizontal axis of the graph and a verticalline drawn.2. The design compression capacity required(unit: kN per linear metre) is plotted on thevertical axis of the graph and a horizontalline drawn.3. The intersection between the vertical linecorresponding to the concrete thicknessand the horizontal line corresponding to thedesign compression capacity determines theIsolan element type and diameter/number ofcompression bars.FZ Elements1. The concrete thickness is selected on thehorizontal axis of the graph and a verticalline drawn.2. The design tensile capacity required (unit:kN per linear metre) is plotted on thevertical axis of the graph and a horizontalline drawn.3. The intersection between the vertical linecorresponding to the concrete thicknessand the horizontal line corresponding to thedesign tensile capacity determines theIsolan element type and diameter/numberof tension bars.Calculation MethodA hard copy of the calculation to derive theload graphs is available from Ancon on request.Balcony DeflectionThe deflection of the equivalent ‘monolithic’balcony should be calculated in the usual way,in compliance with relevant standards anddesign codes. A coefficient of 1.20 must beapplied to the calculated figure to determinethe maximum deflection with Isolan connectors.The final figure can be used to determine theamount of pre-camber to apply to theformwork to compensate for the deflection.Ancon Isolan Product Referencing4MV8 - 200 - 5Ø12T / 5Ø16CNumber of System Number and Number andshear bars, height diameter of diameter ofSystem type, tension bars compression barsDiameter of to be supplied to be suppliedshear bars by others by othersTypical Specification ClauseOnce the appropriate Isolan system has beenselected from the design graphs, the followingclause may be adapted for use.

  16. 16. Isolan®Insulated Balcony Connectors16CORNER DETAILSAt balcony corner configurations, if thediameters of the tensile and compressivereinforcement add up to or are greater than27mm, attention to the local reinforcementdetail is required. This is necessary becausethe inner diameter of the polypropylene tube is27mm and if the tubes are maintained in thesame horizontal plane, the reinforcementwould clash.In the main load bearing direction the Isolanelement is selected to suit the height of theslab, so that the compression reinforcementwhich crosses the 60mm insulation cavity willbe located in the 1st layer (bottom steel) andthe main tensile reinforcement will be located inthe 4th layer (top steel). Refer also to Plan Viewof Cantilever Balcony and Sections.Plan View of Cantilever Balcony and SectionsKey to Reinforcement Layers2442Compression reinforcement - 1st layerTop of cantilever slabTensile reinforcement - 4th layer4MV6-200 4MV6-200 4MV6-200Tensilereinforcement -3rd layer4MV6-1604MV6-180or4MV6-200113 34th layer1st layer3rd layer2nd layerAs previously noted, the corner detail isdependent upon the reinforcement diameters;the size of the Isolan element at corners needsto be selected to avoid local clashing ofreinforcement. A typical plan of a cornerbalcony is shown below, and the Isolanelement selected will be 20mm or 40mmsmaller in height than that adopted for thegeneral cantilever design.For example, a cantilever balcony requires astructural slab of height 200mm, accordingly anIsolan MV 200 element would be selected,however locally at the external corner an Isolanelement MV 160 is selected to avoid clashing ofreinforcing bars. The Isolan MV 160 element ismade up to the full slab height of 200mm byusing 20mm thick polystyrene make-up stripsglued to the top and bottom edges.Similar detailing principles will apply torecessed balconies.Compressionreinforcement -2nd layerNotes:1.

  18. 18. 18INSTALLATIONAncon Isolan components are fast and simple to install. These steps are provided as guidanceand should be followed in conjunction with the site engineer’s instructions and structuralengineer’s reinforcement details.Any polystyrene which is damaged must be replaced or alternatively, where possible, patched withpolyurethane foam to maintain the insulation properties.Step 1The Isolan system should always be orientated so the stainless steel shear reinforcing bars are atthe bottom of the slab on the side of the load (the balcony side). The unit is then positioned andsecured to the formwork.On-site StorageCare should be taken to avoid damaging anyIsolan components prior to installation. Specialcare should be taken of the polystyrene units.All components should be stored under coverand away from direct sunlight.Special ConfigurationsLoad distribution reinforcing bars must beinstalled at the bends of the shearreinforcement.Balcony - Loaded sideNote: For clarity, not all reinforcement is shown.Shear reinforcementpositioned at bottom of slab60mm1000mmIsolan unitCompressionreinforcement(other bars omittedfor clarity)25mm maximum out ofalignment over 1000mmPolypropylene tubesStep 2Insert the compression bars and tension bars, supplied by others, through the polypropylenetubes, and secure them to the main floor slab and balcony reinforcement. The minimum anchorlength must be achieved either side of the Isolan system, see page 17 for detailed dimensions.Care should be taken to ensure that any misalignment of the compression bars does not exceed25mm in 1000mm (1 in 40) as illustrated in the Part Plan View diagram.Step 3The concrete should preferably be poured adjacent to the Isolan system and simultaneously toeither side to avoid any displacement of the polystyrene units.

Tel: +44 (0) 114 275 5224 Web: Continuity SystemsReinforcement Continuity Systems are anincreasingly popular means of maintainingcontinuity of reinforcement at constructionjoints in concrete; they eliminate the need todrill shuttering and can simplify formworkdesign, thereby accelerating the constructionprocess. The Ancon Eazistrip System isCARES approved and is available in bothstandard units and special configurations.Reinforcing Bar CouplersThe use of reinforcing bar couplers canprovide significant advantages over lappedjoints. Design and construction of the concretecan be simplified and the amount ofreinforcement required can be reduced. Thejoint can also remain unaffected by any loss ofcover because the strength of a mechanicalsplice is independent of the concrete in whichit is located. The range includes threaded andmechanically bolted couplers.Shear Load ConnectorsAncon DSD Shear Load Connectors are usedto transfer shear across expansion andcontraction joints in concrete. They are moreeffective at transferring load and allowingmovement to take place than plain dowels,and can be used to eliminate double columnsat structural movement joints in buildings.The two-part construction of these connectorsensures alignment, vital where movement isrequired. The Ancon DSDQ features arectangular box section to allow lateralmovement in addition to longitudinalmovement.Punching Shear ReinforcementUsed within a slab to provide additionalreinforcement around columns, Ancon Shearfixis the ideal solution to the design andconstruction problems associated withpunching shear. The system consists ofdouble-headed studs welded to flat rails,positioned around the column head.The shear load from the slab is transferredthrough the studs into the column.Channels and Bolts for Fixing to ConcreteCast-in channels are used for fixing masonrysupport systems to the edges of concretefloors and beams. Channels are available indifferent sizes ranging from simple selfanchoring channels for restraints, to largecapacity channels with integral anchors.A selection of channels can also be suppliedplain-backed for surface fixing. Stainless steelexpansion bolts and resin anchors completethe range.THE ANCON ‘PRODUCTS FORSTRUCTURAL CONCRETE’ DIVISIONAncon operates a dedicated service to clientsin the concrete sector.
