10 Installation and Application Safety regulations Identification Installation and application Te transport ancor system is made up of te permanently cast-in transport ancor and te temporarily connected lifting equipment. Te basic principles for dimensioning and application of transport ancors can be found in te VDI/BV-BS guidelines Te metods in te guidelines represent current tecnology. Te regulations require te following safety factors: Failure safety factors Steel failure of ancors: = 3.0 Concrete failure*: = 2.5 Failure in te lifting-link: = 4.0 * A safety factor of = 2.1 can be assumed for transport ancors installed in a continuous supervised factory environment. For safety reasons, te installation and application instructions for DEHA Lifting systems must always be available at te place of use. Te installation and application instructions must be readily available on site, in te precast plant or on te construction site. Te plant or site manager must ensure tat te operator as read and understood te installation and application instructions for tis system. All DEHA Lifting and oisting equipment are clearly and visible marked. According to (VDI/BV-BS Rictlinie 6205 safety regulations for lifting ancors and systems, identification marking of all lifting elements must remain clearly visible, even after installation.

Transport ancors wic are incorrectly installed, defective or damaged (for example corrosion damage or wit visible deformities) must not be used for lifting. Stainless steel transport ancors Transport ancors may not be used repeatedly. Multiple lifting in te normal sequence of transporting and loading, troug to final erection is not defined as repeated use. Transport ancors for permanent use in crane ballast etc. must be made of stainless steel in accordance wit te approval regulation; approval no. Z Quality control All transport ancors and systems are quality controlled in accordance wit DIN EN ISO 9001 and in accordance wit te Quality Assurance and Test Specifications of te German certifier RAL Gütegemeinscaft Verankerungsund Bewerungstecnik e.v..

Te ancor may not be used if tere is damage to te concrete wic may reduce te load capacity. 10

11 Installation and Application Criteria for ancor selection Maximum load capacities, edge distances and installation values can be found in te respective tables. Irrespective of te selected ancortype (selected according to te load acting on te ancor) te following factors must be taken into account for calculation: weigt of precast element of ancors ancor layout of load bearing ancors spread angle in te oist ancor diagonal pull properties dynamic loads adesion to te formwork Ensure sufficient reinforcement if slabs are cast in te orizontal and subsequently lifted uprigt witout a tilting-table. Number of ancors Te of ancors determines te type of oist tat needs to be used. A oist wit more tan two cables is statically indeterminate if te ancors are aligned along a single axis. Hoists wit more tan tree cables are deemed statically indeterminate if measures are not taken to ensure te load is distributed amongst all ancors (for example; wit a spreader beam etc.). Installation and application DEHA Sperical ead lifting ancor systems sould only be installed wen te following tecnical specifications and requirements ave been met: load capacity edge spacing concrete grade load direction additional reinforcement capacity Te load capacity of te ancor depends on: concrete compression strengt f ci at time of lift (cube-test cm) ancorage lengt of te ancor edge and axial ancor-spacing load direction reinforcement layout Calculating te tension load As a rule te tension-force Z in te ancor is calculated using te following formulae: case; removing te formwork F Z = F G z / n or F Z = (F G + q ad A f ) z / n case; transport F Z = F G z dyn / n Abbreviations: F Z F G A f n = tension force on te ancor [kn] = element weigt [kn] (according to DIN (06/2002) specific weigt of = 25 kn/m 3 ) = contact surface between te concrete and formwork [m 2 ] = of load-bearing ancors z = spread angle factor = formwork adesion factor dyn = dynamic factor q ad = base value for formwork adesion F ad = effective load caused by formwork adesion [kn] 11

12 Installation and Application s at te ancor Dead weigt Element weigt is defined as: Volume of te element specific weigt of te concrete Increase factors: Spread angle Dynamic loads Non-symmetrical ancor layout F GT Te effect of dynamic loading depends mainly on te lifting equipment between te crane and te load lifting ead. Te load in eac ancor is calculated using bar statics if te ancors are not installed symmetrically to te load s centre of gravity. F Z = 0.5 G β = 0.52 G = 30 = 0.54 G = 0.58 G = 0.7 G = 1.0 G =0.54 G not allowed F = 0.52 G = 0.58 G = 0.7 G = 1.0 G F Z = 0.5 G Spread angle factors Cable angle Spread angle Factor z G Cables made of steel or syntetic fibre ave a damping effect. Wit increasing cable lengt te damping effect is increased. However, sort cains ave an unfavourable effect. Te forces acting on te lifting ancors are calculated taking te sock factor dyn into account. Dynamic-factors dyn * Lifting unit Stationary crane, swing-boom crane, rail crane Lifting and moving on level terrain Sock factors dyn * Lifting and moving on uneven terrain 4.0 * If oter values from reliable tests or troug proven experience are available for, dyn ten tese may be used for calculation. For oter transport and lifting situations te coefficient dyn is defined troug reliable tests or proven experience. Uneven loading of te ancor caused by non-symmetrical installed ancors in respect to te load s centre of gravity: F Z,a F GT F G Te load s centre of gravity will always stabilise verticality under te crane ook. distribution in non-symmetrical installed ancors wen using a spreader beam is calculated as below: F Z,a = F G b / ( a + b ) F Z,b = F G a / ( a + b ) Note: To avoid precast elements anging at a slant wen being moved te ook in te spreader beam sould be directly above te centre of gravity S. If lifting elements witout a spreader beam ten te transport-ancors sould be installed symmetrically to te centre of gravity

13 Installation and Application s on te ancors Adesion Adesion: Adesion forces Increased adesion Striking te formwork Depending on te material used for te formwork te adesion between formwork and concrete can vary. Increased adesion must be assummed for - panel and coffered ceilings slabs. Adesion to te formwork sould be minimised before lifting by removing as many parts of te formwork as possible. Spreader beam Te following table can be used as a reference: To simplify calculation, a multiple of te mass is used: Adesion to te formwork Lubricated steel formwork q ad 1 kn/m 2 Varnised timber formwork q ad 2 kn/m 2 Roug formwork q ad 3 kn/m 2 Increased adesion to te formwork - panel = 2 Ribbed panel = 3 Waffled panel = 4 A Te adesion value (F ad ) for te formwork is calculated wit te following equation: F ad = q ad A f Surface of te cast slab attaced to te formwork before lifting. Substantial load increase can also be encountered wen components are lifted parallel or near parallel to parts of te formwork. Tis applies to ribbed slabs and coffered ceiling slabs and can also apply to vertically cast columns and slabs. Use a wedge to carefully prise te formwork from te ardened concrete, if it proves difficult to remove. 13

14 Installation and Application Tensile loads at te ancors Axial pull β: 0 up to 10 Diagonal pull lift β: 10 up to 60 Tilting 90 Not recommended for angles > 45 Te transverse pull reinforcement can be omitted wen using a tilting table and a load angle of < 15.

15 Installation and Application Statical systems Ancor layout in slabs In general it is impossible to calculate te precise load per ancor in a beam wit more tan two suspension points and in a panel wit more tan tree suspension points; even if te ancors are arranged symmetrically to te load centre. Due to unavoidable tolerances in suspension systems and in te position of ancors, it can never be determined weter te load is distributed equally amongst all ancors. Examples Using tree ancors ensures a static determinate system. Using tolerance-compensating suspension systems permit exact load distribution (e.g. articulated lifting beam combinations, multiple slings wit compensating rig, etc.). Tis type of system sould only be used by experienced specialists; also bear in mind tat tis system must be used bot in te yard and on site. Wit four independent cable runs or two single diagonal cables, only two ancors can be assumed to be loadbearing. If in doubt assume only two ancors are load bearing (BGR 500 C. 2.8 Point 3.5.3). Te use of two ancors is recommended for beams and uprigt panels, and four ancors installed symmetrically to te load centre is recommended for orizontal slabs. In bot instances, it can be assumed tat two ancors will be bearing equal loads. A perfect static weigt distribution is acieved by using a spreader beam and two symmetrical pairs of ancors.

Te system wit compensating rig makes it possible to distribute te load evenly over 4 ancors. A perfect static weigt distribution can be acieved using a spreader-beam, wic avoids diagonal pull.

16 Installation and Application Ancor installation and application Static ystem Transport ancors are made out of killed steel wit a ig notc tougness wic retains its safe load capacity under sock load in temperatures as low as minus 20 C. Transport ancors production is DIN EN ISO 9001 certified and is subjected to continuous monitoring. Te sperical ead transport ancor is cast in wit te recess former attaced. After te concrete as set te recess former is removed; te lifting link can ten be attaced to te transport ancor. Te connection fulfils all work regulation safety requirements; te transport ancor is in a recess, tere are no protruding parts in te finised elements. Crane ook Cast-in ancor wit recess and attaced lifting link Te HALFEN product range wit its wide selection of transport ancors in various load es and lengts guarantees tat for nearly every sape of reinforced concrete precast element te required tecnically, correct solution is available and remains cost-efficient for conventional building projects (beams, ceiling slabs, trusses, columns and stairs); and also for utility and excavation projects (pipes and safts). Overview of transport ancors Lifting link; load Transport ancor; load Transport ancor lengt and 1200 Universal ead lifting link Advantages: Safety is te priority wen moving or transporting precast elements. Te cast-in forged steel sperical ead transport ancors include large safety factors against steel and concrete failure. Te load is clearly marked on all ancors; on some ancors te lengt is also marked. Tere is no risk of using te wrong parts in any load. Te lifting link (te universal-ead-clutc) is wear resistant even in te rougest construction situations. Te system guarantees fastest possible ancor installation in precast elements and due to te special construction te crane ook is connected witin seconds to te precast element. Ancor installation using te system accessories is remarkably easy. Engaging and disengaging te universal lifting link fitted to a crane-cable wit te transport ancor is easy and can be done wit one and.

17 Installation and Application transfer and failure beaviour Te sperical ead ancors for load 1.3 to 45.0 are forged from rod material. Depending on te application, ancors are available in different lengts. Longer ancors are available if reduced edge spacings or low concrete strengts need to be considered. In typical wall ticknesses te concentrated load distribution as displayed by te sperical ead transport ancor foot as advantages in comparison wit gradual, supposedly smoot load distribution effecting from ribbed steel. Tis as been proved in numerous tests by te Institute for Concrete and Masonry Construction at te Tecnical University of Darmstadt (Institut für Massivbau der TU Darmstadt). Te universal ead lifting link rests against te concrete in diagonal pull and transfers te orizontal load factor directly into te concrete. Te load transfer into te concrete is via te ancor foot. Tis allows ig possible loads wit relatively sort ancor lengts. In very tin elements tese concentrated loads leads to lateral spalling caused by ig tensile splitting. A typical failure pattern in tests is a cone saped failure originating from te foot of te ancor. By using a longer ancor a larger area is utilized to distribute te load in te concrete. Consequently tere is no reduction in load bearing capacity to account for diagonal loading in large surface elements. For example; as is standard for sleeve ancors. Additional reinforcement is not required. Additional diagonal bursting reinforcement is required in tin wall elements. Details can be found in te section sperical ead transport ancor for beams and walls. Expected failure if ancor load is too ig Blow-out failure only in very tin elements A tilting aid is required wit transverse stress in tin wall elements at 90 degrees to te slab surface. A tilting ancor can be used for load 2.5 and 5.0. We generally recommend using a tilting-table. Compared wit oter transport ancor systems te symmetrical design of te ancor foot does not require specific placement wen installing te ancor (rotational symmetry). Te lengt of te sperical ead transport ancors depends on te concrete cross-section and concrete grade, and are designed for optimal load capacity. Welding and adapting te sperical ead transport ancors especially near te ead and foot is not permitted. Multi-layer elements can be moved using te offset sperical ead rod ancor or te offset sperical ead transport ancor. Furter information can be found in te section spericalead transport ancors and off-set sperical ead ancors. 17

Te u-bars sould be distributed on eac side of te ancor in an area 2.5 te ancor lengt, te first u-bar on eac side must be as close as possible to te recess former. Diagonal pull reinforcement is only needed if β > 30. Diagonal pull reinforcement may not be required if te edge distance is greater (see load tables).
