INTRODUCTION For the transportation, lifting and mounting of concrete elements the best choice is to use the T-Slot- anchor system. This lifting

system is the safest method to transport concrete elements through the air. The system is fast to use and the use of a cheap T-

Slot-anchor makes the application of this lifting system the most economic system.

The T-Slot-anchor system exists of three main products. That is a T-Slot-anchor which is poured in concrete together with a

rubber recess former and a TH2 lifting clutch, which can be used for a long time (picture 1).

Picture 1

The T-Slot-anchor is built in the concrete element with the aid of a rubber recess former. After the pouring of the shuttering and

after the concrete is hardened, the rubber ball can be removed. The TH2 lifting clutch fits exactly in the created hole and the

prefab element can be pulled up out of the shuttering.

PRODUCTS RANGE

LIFTING SYSTEM

LIFTING CLUTCHES

“Terwa” offers different lifting clutches and a wide range of different recess formers. The difference between all systems is

actually defined by the type of anchors.

TRANSPORT ANCHORS The anchors are forged from round carbon steel; for 45 t anchors alloyed carbon steel is used. Available in black (without

surface treatment but slightly oiled) or hot dip galvanised. A small range of stainless steel anchors (A2) is available as well. All

anchors are designed to fulfil a minimum safety factor c=3.

RECESS FORMERS AND ACCESORIES The anchors are fitted in the mould with a recess former. Obviously, the recess formers are available in the same range as the

lifting clutches and the anchors. This is indicated by a load group, marked on the top.

The formers are mounted on the mould with fixing plates.

TECHNICAL INFORMATION – CHOOSING TYPE OF ANCHOR

SAFETY RULES The anchors are embedded in the concrete elements. The lifting system is only connected to the anchor when required for lifting. It is essential, in designing the lifting system, to use the following safety factors against breaking:

For steel component c = 3

For concrete element c = 2,5

For cable wires c = 4

LOAD CAPACITY The load capacity of the anchor depends on multiple factors such as:

The deadweight of the precast concrete element “G”

The strength of the concrete at the time of operating: lifting or transporting

The embedded depth of the anchor

The edge distance and spacing of the anchors

The load direction

The reinforcement arrangement

1) WEIGHT OF PRECAST UNIT The total weight “G” of the precast reinforced concrete element is determined using a specific weight of: ρ = 25 kN/m³ For

prefabricated elements are composed of a higher concentration of reinforcing elements in the calculation of weight will take this into account.

G = ρ x V V = L x l x s

V - volume of precast unit in m³ L – length in m l – width in m s – thickness in m

Picture 2

2) ADHESION TO FORMWORK COEFFICIENT Adhesion forces between the mould and the concrete depend on the type of mould used. Take account of

Oiled formwork

Taking away the side formwork

The value “Ha” of adhesion to the mould is calculated through the following equation:

Ha = q x A (kN)

Where: q – the adhesion to mould factor according with the material of the mould y – the form factor (adhesion to mould factor according with the form of the element) A – area of contact between the mould and the concrete unit when starting the lift.

For smooth oiled steel mould q = 1 kN/m ²

For smooth varnished timber mould q = 2 kN/m ²

For rough timber mould oiled q = 3 kN/m ² - Double-T slabs (picture 3)

Ha = 2 x G

- Ribbed elements

Ha = 3 x G

- Coffered elements

Ha = 4 x G

Beam or pillar 1,0 ÷ 1,10

Vertical plate 1,10 ÷ 1,15

Horizontal plate 1,2 ÷ 1,25

Floor plates with cassettes > 2,0

Adhesion to the mould should be minimized before lifting out of the mould by removing as many parts of the mould as possible.

3) DYNAMIC ACCELERATION COEFFICIENT (LIFTING LOAD COEFFICIENT) When the movement of the precast units is performed by lifting gear, dynamic forces which depend on the type of lifting gear used appear. Estimation has to be made of the appeared dynamic forces as a result of the lifting or transport method. Lifting with a stationary crane, with a fine hoist possibility reduces these forces, while the forces will be increased enormously when lifting on the building site with a forklift truck. For cranes with precision lifting, the lifting load coefficient is f = 1,1 ÷ 1,3 When transporting suspended precast elements over uneven terrain, the lifting load coefficient used is f > 2. During the detaching out of the formwork dynamic forces will occur. The size of the dynamic forces depends on the form of the element, the formwork and the use of additions for the detaching out of the formwork. The table gives some indications for the dynamic factor value which can be used. Table 3

*) lower values may be appropriate in precast plants if special arrangements are made.

4) ASYMETRIC DISTRIBUTION OF THE LOAD

The load of each anchor depends on the embedded position of the anchor in the precast unit and also on the transporting mode:

a) If the arrangement of the anchors is asymmetrical in relation to the centre of gravity, the individual anchor supports different loads (picture 4). These loads are calculated through the following equation:

Fa = Ftot x b / (a + b)

Fb = Ftot x a / (a + b)

Note: To avoid tilting of the unit during transport, the load should be suspended from the lifting beam such that its centre of gravity is directly below the crane hook.

Picture 4


3D-VERSION 08-2013


b) In the case of transporting without lifting beam, the load on the anchor depends on the cable angle (ß).

5) LIFTING IN AN ANGLE – CABLE ANGLE COEFFICIENT

The cable angle ß is determined by the length of the suspending cable. We recommend, if possible, that ß should be kept to a minimum ß ≤ 30°(picture 5). The tensile force on the anchor is increased with an angle coefficient z (table 5).

F = z x Ftot / n where: z = 1/ cosß n = number of load bearing anchors

Through a right position of the anchors, the same load per anchor can be realized. In the case that one anchor is more heavily loaded than the other anchor, this anchor has to be chosen for this loading. It is better to apply anchors of the same kind per lifting situation. Determine the lifting angle of the hoist cable in relation to the length axle of the T-Slot- anchor. This depends on the adjusting of the length of the hoist cables and the position of the lifting anchors. After determining the lifting angle, the calculation factor follows via the table for the force in the lifting cable.

α = 2 x ß

7) DETERMINATION OF TOTAL LOAD

Total load of precast unit for calculating the anchor is determined through the following equation:

- When de-mould Ftot = (G x y + Ha)

- When pitching Ftot = G

- When transporting Ftot = G

8) DETERMINATION OF ANCHOR LOAD

The load on each load bearing anchor is calculated with the following formula:

- When de-mould F = (Ftot x f x z)/n = [(G x y + Ha) x f x z]/n

- When pitching F = (Ftot/2 x f x z)/n = (G/2 x f x z)/n

During tilting, the concrete element remains supported on the ground, only the half of the forces have to be taken into account. In the situation of pitching, load carrying capacity of sockets and anchors is limited to 50% of the axial load.

When lifting F = (Ftot x f x z)/n = (G x f x z)/n

When the action force of the most heavily loaded lifting is determined the choice of the type of the lifting anchor must be made. By means of the acting forces the type of the T-Slot-anchor can be determined. With the aid of the added tables can be determined which length of the T- Slot-anchor must be used dependably of the present concrete strength. When lifting in an angle by using T-Slot-anchors no reduction is needed on the permissible load. For the vertical setting of small elements split reinforcement can be necessary by reason that the pressing force of the lifting hook will lead directly his forces into the concrete. In these cases it is good to work with the TKA-Tilt Slot-anchors. Split reinforcement can be adjusted in the following way. The lifting clutch directly leads the pressing force to the concrete and starts approximately half way of the recess former. That is why the split reinforcement must be applied. See the drawing.

Picture 6 Picture 7

9) ANCHORING OF T-SLOT-ANCHORS

If the loading type of the T-Slot-anchors has been chosen, the length of the anchor has to be determined. Dependably of the form of the element and the strength of the concrete at the first loading, a T-Slot-anchor has to be chosen, which realizes a larger anchoring force than is calculated as the acting force. The admissible anchoring force is calculated with a safety factor of 2,5.

n = 4

n = 4

-A perfect static weight distribution can be obtained through the use of a lifting beam and two pairs of anchors set out symmetrically.

- A perfect static weight distribution can be obtained using a crossed spreader beam, which avoids angled pull.


3D-VERSION 08-2013


The foot of the T-Slot-anchor obtains the anchoring. At collapsing of the concrete a dish formed foot arises of the T-Slot-anchor a break out cone with an incline of 1:3. That is why those relatively small anchoring lengths will do. In this technical documentation tables are added, to which in practice most of the situations can be filled in. It is also possible to make an exact calculation of the present situation. On request special tables can be made which fulfil the practical situation in the prefab factory or at the building site.

If it is possible divide elements in the groups below, than the following rule of thumb can be used. In case of inexperience with the 3D Slot-anchor system, additional information is always obtainable at “Terwa”. Type of element:

Beams: T-Slot-anchors with the standard length per loading type can be used.

Horizontal plates T-Slot-anchors with a smaller length than standard can be used.

Vertical plates T-Slot-anchors with a larger length than standard must be used. OVERVIEW OF T-SLOT-ANCHORS LENGTHS

All deliverable types of T-Slot-anchors are mentioned in the product documentation and the pricelist and can be delivered in untreated, hot dip galvanizing or electrolytic galvanizing and stainless steel. The calculation of the anchoring length can be done with the aid of empiric found formulas, with the VBC-90 or according to the rules being in preparation of the CUR-working group “Anchors in concrete”

Picture 8

When calculating the admissible anchoring force, besides the length of the T-Slot-anchor, the present concrete strength is of main importance. Mostly the deforming strength is leading or the concrete strength that is realized at the first loading of the anchors. If there is any doubt about the admissible concrete force or that it is not possible to realize it, additional measurements have to be taken. For instance, the concrete force can be enlarged in the location of the T-Slot-anchor by adjusting isolation material. When you use isolation material, higher temperatures can be reached in the concrete and this gives a quicker force development. The addition of extra reinforcement in the reinforcement nets almost never leads to improvement of the anchoring force. The anchoring force can only increase if the reinforcement is placed around and over the foot of the anchor.

Picture 9

The anchoring force of the T-Slot-anchor is the biggest when the T-Slot-anchor is placed at a distance to the edge which is 3 times larger than the built in depth so that a complete break out cone can be created (picture 8). If it is not possible to have an edge distance to all directions of 3 times the built in depth, a better anchoring must be obtained with the aid of a longer T-Slot-anchor. In the table, a situation is described which fulfils as well the edge distances in all directions of 3 times larger than the built in length as well the situation for which the edge distance is limited to 2 directions. With the aid of these tables a good impression can be obtained of what the real admissible force is in situations that are more or less comparable. In case of doubt, please contact “Terwa”.


3D-VERSION 08-2013


For vertical plates the possibility that a horizontal break out can occur must be taken into account. Here also the present vertical reinforcement has no effect for the anchoring force. The situation in the figure will become very critical if the thickness of the element is smaller than half the thickness of the chosen T-Slot-anchor. In this situation an additional discussion with “Terwa” is necessary.

Picture 10 To enlarge the vertical anchoring a hairpin can be adjusted which falls around the foot. In this situation it is also very helpful to use the TKA-Tilt Slot-anchor, an eye anchor or a rod anchor. With these lifting anchors the anchoring is obtained by a reinforcement hairpin through the eye of the anchor or by a ribbed rod.

CHARACTERISTICS T SLOT ANCHOR

BASIC PRINCIPLES FOR THE ANCHOR SELECTION The T Anchors (picture 11) are forged from round steel and are designed to a load force in the range of 1,3t to 45,0t. Proper for large precast elements such as slabs, beams, panels, pipes. Anchors from 1,3t to 32,0t are made from S355J2 steel and the 45,0t anchors are made from alloyed steel 42CrMo4 (w1.7225-EN-10083-1). In the same load group, anchors are available with different lengths. Longer anchors are installed for reduced edge spacing or for low concrete strengths. The load on the anchor is transmitted to the concrete through the anchor foot (picture 12).

Picture 11 Picture 12 Picture 13

The anchors must be fixed in the mould using recess formers. The recess former retains the anchor securely in position during the concrete pour. The recess former creates a void around the anchor head which corresponds to the lifting system head (shackle). The incorrect coupling of parts of different load groups is impossible. Another advantage is that the shackle rests against the concrete during angled pull and therefore the horizontal load is transferred into the concrete directly (picture 13). For this reason additional reinforcement is not required in large units. In thin walls, additional reinforcement is necessary for angled lift, to absorb the transverse pulling forces.

Note: values in the table above for distance to the edge are valid for unreinforced concrete elements. The distance to the edge can be reduced in reinforced concrete units.


3D-VERSION 08-2013


REINFORCEMENT USED IN ANCHOR ZONE FOR AXIAL PULL, IN PANELS OR BEAMS Panels and beams containing only basic reinforcements such as wire mesh, stirrups and edge reinforcement must only be lifted in the axial direction or at an angle not exceeding 30° (picture 18). The stirrups (table 10) will be installed on both sides of the anchor on an area equal to 2,5 x length of anchor. Those two stirrups in the vicinity of the anchor should be installed as close as possible to the recess former.

REINFORCEMENT USED IN ANCHOR ZONE FOR ANGLED LIFT IN PANELS OR BEAMS For angled pull it is required an additional reinforcement installed in opposite direction of the load (picture 22). It is recommended to install this angle pull reinforcement as close as possible under the recess former and with full contact to the anchor. The additional reinforcements necessary in the anchor zone for lifting the panels and beams at angles ß ≤ 45° are shown in the pictures bellow and table 12, the concrete strength must be at least 15 N/mm². It is recommended that the angle ß, where possible, should not exceed 30 °. The stirrups (picture 19) will be installed on both sides of the anchor on an area equal to 2,5 x length of anchor. Those two stirrups in the vicinity of the anchor should be installed as close as possible to the recess former.

For angled pull at an angle 30°≤ ß ≤ 60° it is recommended to install an additional reinforcement in opposite direction of the load (picture 24).

This reinforcing must be installed as close as possible under the recess former and with full contact to the anchor. Angle lift without the use of this reinforcement is only permitted when the edge distance is increased(a).

O-EYE- ANCHOR Forged from carbon steel, O-eye anchor are designed to load forces in the range of 1,3t to 32,0t (table 16). The O-eye-anchor is provided with a hole, in which a reinforcement hairpin has to be placed to obtain a good anchoring in small elements, lightweight pre cast elements such as pre-stressed beams (picture 30). Since the entire load is transferred to concrete reinforcement steel, it should be installed so as to maintain direct contact with the bottom of the anchor hole. Use of this reinforcement is essential. Do not use anchors type O without this reinforcement. For angled lift is necessary to use an additional reinforcement, similar to that mounted with t-slot anchor. It is recommended to install this angle pull reinforcement as close as possible under the recess former and with full contact to the anchor.

TKA-TILT SLOT-ANCHOR Forged from carbon steel, they are designed to a load force in the range of 1,3t to 5,0t (table 18). TKA anchors can carry loads of between 1,3t and 5,0t. These anchors are used for tilt and transport thin concrete walls . Usually this type of anchor is used together with additional reinforcing steel. The TKA anchor must be fixed in the mould using a specific recess formers RBK (picture 33). The recess former retains the anchor securely in position during the concrete pour. The IPK is mounted in the RBK in order to stabilize the RBK during pouring and hardening.

REINFORCEMENTS TYPES USED IN THE ANCHOR ZONE FOR PANELS AND BEAMS FOR ANGLE LIFT Panels and beams containing only basic reinforcements such as wire mesh, stirrups (picture 45) and edge reinforcement (picture 46) must only be lifted in the axial direction or at an angle not exceeding 30 °. For angled pull is required an additional reinforcement (picture 47) installed in opposite direction of the load. It is recommended to install this angle pull reinforcement as close as possible under the recess former and with full contact to the anchor. The additional reinforcements necessary in the anchor zone for lifting the panels and beams at angles ß ≤ 45° are shown in the table 26 – picture 48, the concrete strength must be at least 15 N/mm². It is recommended that the angle ß, where possible, should not exceed 30 °. The stirrups will be installed on both sides of the anchor on an area equal to 2,5 x length of anchor. This two stirrups in the vicinity of the anchor should be installed as close as possible to the recess former.

LIFTING CLUTCHES TH2 AND THR2 The 3D Lifting Systems TH2 (picture 54) and THR2 (picture 55) are made of high quality steel and they are designed with a safety factor of 5. Every Lifting System is individually tested and is supplied with a unique certificate. The safety factor is 3 times the working load. The special design of the clutch ensures a tight and safe connection to the anchor. Obviously, the shackle fits the hemispherical cavity created by recess former perfectly. The lifting clutch, recess former and anchor only correspond when they are from the same load group. The load group is clearly marked on the lifting clutch ( table 30 and table 31).

OPERATING INSTRUCTIONS

Picture 56 Picture 57 Picture 58 Picture 59

1 2 3 4

The clutch is brought in the right position.

Rotate the shackle, until the opening corresponds with the anchor head.

The shackle rotates to its locking position.

The nose of the shackle is pushed against the concrete element.


3D-VERSION 08-2013



When pitching the concrete unit with the 3D Lifting System, the nose must be in the same direction with the load (picture 61). Due to the counterweight of the nose, the shackle remains connected, even in an unloaded state. To release the 3D Lifting System, the load hook is lowered and the shackle is turned up and out (picture 62 and picture 63). Only after the Lifting System is completely detached of the recess and anchor, the crane can be withdrawn. The 3D lifting System can remain attached to the crane hook till another use.

If the shackle remains in the position showed above, the lifting of the concrete unit is not possible.


3D LIFTING SYSTEM MAINTENANCE In common with all lifting devices, the lifting system TH2, THR2 must be checked at least twice a year by trained personnel. Any defects found should be corrected before use. It is important to determine the amount of wear. The lettering and identification of the lifting system must be visible. If the shackle is deformed or the mouth opening is enlarged, the 3D Lifting System must be taken out of use and cannot be repaired. If the limiting dimensions given in the table 32 and table 33 are exceeded for “H” or fall below for “M” a further use of the Lifting System is not safe. Repairs, especially welding operations to the Lifting System are strictly forbidden. Do not combine our products with accessories from other manufacturers.

ATTACHMENT OF THE SLOT - ANCHORS IN CONCRETE To link together the TH2 lifting clutch with the T-Slot-anchor there must be a cavity in the concrete. This cavity has a spherical form and can be either a half ball or a small ball slot. Different aiding kits are available to realize this recess. For a half ball cavity the TH2 lifting clutch can be attached in any direction and eventually can turn during lifting in the cavity till the lifting hook has arrived in its good position. The most usable is the RB recess former.


3D-VERSION 08-2013


RECESS FORMERS The anchors are fitted in the mould with a recess former. The cavity former, enables the lifting clutch to fit over the anchor. Because of the special design, there is no sharp edge in the precast element. Obviously, the recess formers are available in the same range as the lifting clutches and the anchors. This is indicated by a load group, marked on the top. The formers are mounted on the mould with fixing plates. After de-mould of the element, the recess formers can be removed easily. Another option is represented by the magnetic and steel recess formers.

The standard recess formers are manufactured out of rubber shore 65° - 70°. The rubber used has a good resistance to de-

mould oil. The formers will keep their original shape, even when they are heated up to 120°C. They can be used many times. The magnetic recess formers are manufactured without rubber. RB – STANDARD RUBER RECESS FORMER

The RB recess former is used in combination with the T slot anchor, O-anchor, TPA anchor, TKS anchor and TSG anchor.

GENERAL INSTRUCTIONS FOR INSTALLATION AND USE RUBBER RECESS FORMERS

If the formwork can only be removed sideways, the fixing plate with a threaded rod IPD or IPDV should be used.

Picture 76

If the formwork can only be removed vertically, the fixing plate IP in combination with the threaded screw TDV should be used.

Picture 77

The fixing plate with a threaded rod IPD or IPDV and the anchor are fitted in the opened recess former (picture 78). The recess former is mounted to the formwork with the wing nut (picture 79). The nut is then tightened securing the recess former and the anchor firmly in position.


3D-VERSION 08-2013



Picture 80

In case of wooden formwork, the recess former can be mounted with the OPR mounting plate. The pins on the OPR ensure that the recess former remains closed during the process of pouring concrete. The OPR is mounted to the formwork with nails (picture 80).

CORRECT INCORRECT Picture 81 Picture 82

REMOVAL OF THE RUBBER RECESS FORMER

Two pieces of re-bar steel can be inserted in the recess former holes (picture 83). With the use of these rods, the former bends open and it can be taken from the anchor (picture 84, picture 85)). Before this, the excessive concrete should be removed. Do not use a hammer or any other tools. This can damage the recess former.


3D-VERSION 08-2013



STEEL AND MAGNETIC RECESS FORMER


The steel recess formers are always used in combination with a rubber ring (picture 86). The magnetic recess formers are always used in combination with a P anchor with collar (picture 88). The rubber ring ensures that the anchor is fitted tight in the former. Moreover, the rubber ring prevents concrete pouring in the recess former. It is recommended that both the anchor head and rubber ring are greased with formwork oil before installation. When the pre cast element is lifted out of the mould, the anchor and the rubber ring detach themselves easily from the recess former. When using the magnetic recess former it is very important that the surface of the formwork is clean. After de-mould the magnetic former can be removed from the formwork with a screw.

WELDING TO THE ANCHORS Welding to the anchors, for instance, the reinforcement mesh is NEVER allowed. The choosing of the material for the anchors

in order to obtain the smallest anchor in relation to the highest safety does not allow any welding under normal circumstances. All the situations mentioned in this leaflet are valid for most of the cases. For variant situations or elements for which this instruction cannot be used you can always get advice from “Terwa”.

CALCULATION OF THE T-SLOT ANCHOR The best way of calculating the lifting anchors is step by step. The following steps are in the correct sequence: Determine the weight of the element.

- The element will be taken out of the oiled steel formwork with a portal crane. There is work with an equator to prevent that the angle to the concrete becomes smaller than 75º (ß = 15,0° table 5, page 8). The used cable angle factor will be z=1,04. Will also be taken into account: a lifting load factor f=1,3 (table 3, page 7) and a form factor y=1,2. (table 2, page 7).

Situation at the building site:

- The element will be lift with the aid of a turning crane. There is work with 2 clutches and equator to prevent that the angle to the concrete becomes smaller than 60º (ß = 30,0°, table 5, page 8). The cable angle factor that must be used is z=1,16. Will also be taken into account: a lifting load factor of f=1,3 (table 3, page 7).

Determination of the lifting force per anchor:

- In the prefab factory: Ha=q x A= 1,0 x 5 x 2 = 10 kN (q = 1,0; oiled steel mould – page 6)

Force per anchor: F = [(G x y + Ha) x f x z]/n=[(50 x 1.2 + 10) x 1.3 x 1.04] / 4 = 23,66 kN → normative

- At the building site:

Force per anchor: F =(G x z x f) /n = (50 x 1.16 x 1.3) / 4 = 18,85 kN

The situation at the works during de-mould is for the choice of the loading class normative T- Slot-anchor: T -25 kN

Determination of the length of the T-Slot-anchor

According to the following table, the T-Slot-anchor type T -25-120 will already do at a concrete strength of 20 N/mm². The anchor length L=120mm is according with the rules indicated on page 21. “Terwa” B.V. can execute for you a special calculation, for which the exact anchoring length can be calculated. Final conclusion: The floor element can be hoisted with 4 T-Slot-anchors; Type T -25-120 in untreated, hot dip galvanized or in stainless carbon steel. Chosen positions:

Length direction: ca. 1/5 of the length = 1,00 m from the edge Transverse direction: ca. 30% of the width = 0,50 m from the edge Table 50 : Admissible break out forces for bottom plates Values in table 50 are for anchors with a distance to the edge of the element 3 times greater than the built in depth.

Situation in the prefab factory:

- The element will be taken out of the oiled steel formwork with a portal crane with the T-Slot-anchors calculated in example 1. In free storage the façade element will be brought to a vertical position (attention! be careful for damages of the edge or use a TKA-Tilt Slot-anchor to prevent damage). During the time the element is brought in a vertical position, there is worked with an equator to prevent that the angle to the concrete becomes smaller than 75º (ß = 15,0°, table 5, page 8). Hereby the element still rests on the floor so that the T- Slot-anchors only hoist half of the weight. Only when the element is in a vertical position it can be hoisted and the T-Slot-anchors will be loaded with the full weight. That is why the bringing of the element into a vertical position is not a normative loading. Also when de-mould and directly bringing into a vertical position with the aid of 2 T-Slot-anchors to the front side will not give a normative loading as well. While lifting with an equator: The angle to the concrete is about 90º (ß = 0°, table 5, page 8), the used T-Slot-anchor cable angle factor will be z=1,0. Will also be taken into account: a lifting load factor f=1,3 (table 3, page 7) and a form factor y=1,2 (only by reason of de-mould, so not normative; table 2, page 7).


- The element will be lift with the aid of a turning crane. There is worked with 2 clutches and the equator to prevent that the angle to the concrete becomes about 60º (ß = 30,0°, table 5, page 8). The used cable angle factor will be z=1,16. Will also be taken into account: a lifting load factor of f=1,3 (table 3, page 7)

Determination of the lifting force per anchor:

- In the prefab factory: Ha=q x A= 1,0 x 5 x 2 = 10 kN (q = 1,0; oiled steel mould – page 6)

Force per anchor: F = [(G x y + Ha) x f x z]/n=[(50 x 1.2 + 10) x 1.3 x 1.04] / 4 = 23,66 kN


3D-VERSION 08-2013


- In the prefab factory - pitching

Force per anchor: F =(G/2 x f x z)/n =(50/2 x 1.3 x 1.0) / 2 = 16,25 kN

- At the building site - transport

Force per anchor: F =(G x f x z)/n =(50 x 1.3 x 1.16) / 2 = 37,7 kN→ normative

The situation at the building area is for the choice of the loading class normative T-Slot-anchor: T -50 kN. Determination of the length of the T-Slot-anchor"

According to the table, the T-Slot-anchor type T -50-340 will already do at a concrete strength of 20 N/mm². (Minimum anchoring force F= 43,8 kN for a wall thickness - 160 mm – table 52). “Terwa” B.V. can execute for you a special calculation, for which the exact anchoring length can be calculated Final conclusion: The floor element can be hoisted with 4 T-Slot-anchors; Type T -25-120 in untreated, hot dip galvanized or in stainless carbon steel. The facade element can be hoisted with 2 T-Slot-anchors type T -50-340 in untreated, hot dip galvanized or in stainless carbon steel. Chosen positions:

Length direction: ca. 1/5 of the length = 1,00 m from the edge. Transverse direction: in the middle of the material thickness Table 52: Admissible break out forces for façade plates & beams: In this table are listed values for forces on the T-slot anchor on the following conditions: the distance to the edge of the element is more than 3 times the built in depth and the anchor is built in the middle of the material thickness a minimum distance of 500 mm. The values indicated in the table are the minimum anchor forces (kN) at indicated concrete strength (N/mm²).

In free storage, the façade element will be brought to a vertical position by use of a TKA anchor. At bringing in a vertical position there is worked with an equator to prevent that the angle to the concrete becomes smaller than 75º(ß = 15.0°, table 5, page 8). At this time, the element still rests on the floor, so that the TKA anchors only hoist half of the weight. Only when the element is in a vertical position it can be hoisted and the TKA anchors will be loaded with the full weight. That is why the bringing of the element into a vertical position is not a normative loading. While lifting with an equator:

- The angle to the concrete is about 75º (ß = 15,0°, table 5, page 8). The cable angle factor will be z=1,04. Also will be taken into account:
