Electrochemical process. HALFEN bolts are available with special CrVI-free coating.
Zinc galvanised GVs:
Stainless steel A4:Chromium is the most important alloying element in
stainless steel. A specific chromium concentration
ensures the generation of a passive layer on the
surface of the steel that protects the base material
against corrosion. This explains the high corrosion
resistance of stainless steel.

The HALFEN cast-in channels "entirely of stainless steel" are not restricted to any concrete cover since no part of them can corrode.
• Bridge and tunnel construction (e.g. fastening of pipelines) • Construction of sewage treatment plants (fastening of spillover weirs) • Chemical industry (mountings exposed to aggressive substances) • Ventilated façades, e.g. masonry veneer • For all structural reinforced concrete elements requiring larger concrete covers
Corrosion protection of the mill finished weld-on anchor is based on the following concrete cover c:
The HALFEN cast-in channels consisting of a high corrosion resistance (HCR) material are a must in cases of highconcentrations of chlorides, sulphur and nitrogen oxides.
The minimum concrete cover depends on local conditions and/or bid specifications
• Road tunnels• Maritime construction in saltwater• Indoor swimming pools• Areas not routinely cleaned• Poorly vented parking garages• As needed in narrow, heavily travelled city streets

Installing the HALFEN bolts4.1
Dependable assembly with HALFEN cast-in channelsHALFEN bolts can be inserted anywhere in the channel slot, then turned 90° and locked in place by tightening the nut. Do not position bolts at the channel ends past the last anchor (≥ 25 mm from the end of the channel). On channels with bolt anchors, the anchor locations can be seen through the channel slot.
Lock setThe bolt heads must sit flush on both flanks of the anchoring channel and locked in place by tightening the nut with the torque wrench. Observe the torque values shown in the table on the bottom of page 31.
TestPositional marking at the tip of the shank of the HALFEN bolts: After the installation, verify the proper alignment of the bolts via the marking slot at the tip of the shank. The slot must be oriented at a right angle to the longitudinal axis of the channel.
AdjustableThe toothing causes positive interlocking and ensures load transfer in the lengthwise direction of the channel,eliminating any risk of slippage.

The tables following this chapter show the design resistances FRd. The term "design value" represents the current standards based on their new safety concepts and must be strictly differentiated from the previous definition of "allowable value".
Following the adoption of DIN 1045 -1 : 2008-08, the recent anchor channel approvals have also taken the new safety concept into account.As a result, the load capacity rating for channel and screw is as follows:
To date, the verification process has not concurrently become established in all industries. In the areas where the "working load" is the basis, it is still the material on which the admissible load per anchor channel certification is based. This is the case for instance in machine and crane engineering, which, inter alia, still go by global safety concepts. In these cases the following conversion rule applies to the loadcapacity values shown in the tables: (Exception: dynamic loads page 22) :
According to the new standards (e.g. EC2, DIN 1045-1, EC3, DIN 18800-1) the normal loads (working loads) are multiplied by the partial safety factor F and the normal load capacity is divided by the partial safety factor M, yielding the respective ratings identified by the index "d" (design).

HALFEN CAST-IN CHANNEL SELECTED:
HTA 50/30 - 350 - 3 anchors with 2 bolts spacing 150mm (→ p. 20)
required ar = 150 mm (→ p. 23) = act. ar = 150 mm
according to expert report:
FEd = 2 × 9.96 kNFRd = 2 × 14.0 kN >
HALFEN BOLT SELECTED:
2 each HS 50/30 M12x60 8.8 (→ p. 31)
FEd = 9.96 kNFRd = 27.2 kN >
Factors:
Working loads on the curtain wall connector- actual dead load (gravity) Fg = 6.00 kN- actual wind load Fw = 12.00 kN
The calculation example is based on a design with partial safetyfactors (on the load and material side).On the load side, safety factors F are introduced.
For dead load: F = 1.35 (acc. DIN 1045-1)For wind load: F = 1.50 (acc. DIN 1045-1) - Design loads gravity Fgd = F × Fg = 1.35 × 6.0 kN = 8.1 kN- Design loads wind loads Fwd = F × Fw = 1.5 × 12.0 kN = 18.00 kN
Design loads, bearing on the channel:
NEd ≙ BVd = (Fgd × 70 + Fwd × 30) / 130 = (8.1 × 70 + 18.0 × 30) / 130 = 8.51 kN VyEd ≙ BHd = Fwd = 18.0 kN
= arctan (8.51 / 18.0) = 25.3° > 15° Zone 1, ref. p. 20
FEd =

FRd with simultaneous loading in all directions
Explanations to pages 20 - 21
Load capacity when concrete ≥ C30/37 - values inbrackets - admissible only when strain of the concrete in the transverse direction relative to the longitudinalchannel axis is prevented by reinforcement (each one rod BSt 500 S, ds ≥ 8 mm in the area around the HTA anchor) or by cross pressure.
When anchored in concrete of strength class C12/15, the admissible loads for C20/25 must be reduced by a factor

Reduced edge dis tance ar in cases of reduced load capacity FRd for shor t HTA elements
HALFEN CAST- IN CHANNELS HTA AND HZA
Dimensioning
The parenthesized dimensions apply if act. ar ≥ 2 x adm. ar.
Minimum component width b = 2 x ar applies in single channel conf. Determined by channel height, length of anchor and necessary concrete cover “c” per DIN 1045 -1. Parenthesized anchor lengths for HTA 38/17 and HZA 38/23 apply only to non-standard profiles with weld-on anchors. Admissible only for centric tensile stress, and for HZA 41/22 also if exposed to stress in the longitudinal direction of the channel.
In cases of transverse and inclined tensile load the distance from the edge of the unstressed component may be reduced to ar red.= 0,5 x ar or 50 mm if, analogous to the figure on see page 24, an anchor reinforcement is provided. In cases of inclined tensile load ≤ 45° and transverse tensile stress per pendicular to the edge spacings of 75 to 100 mm an anchor reinforcement is required see page 24.
The minimum spacing specified in the table applies to reinforced normal weight concrete of all strength classes ≤ C20/25. If increasing the spacing by 30% there will be no requirements to the reinforcement.
Minimum spacing ar, ae, aa, a f and h
These data do not take into account the effect of thevarious anchoring depths hv. For an exact calculation ofthe necessary minimum spacings, refer to thepublication by Prof. Eligehausen in 1997 ConcreteCalendar, part 2, p. 609 &f.

Dimensioning
When used for instance in shelter construction, HALFEN cast-in channels provide added protection for theshock-resistant mounting of built-in components.
The following conditions must be met:• Minimum component dimensions, axial spacing and edge
distance per official approval ( page 23) must be observed.• For practical applications (normal operating and working
loads, static loads) the load values specified in the DIBtcertifications apply. Accordingly, static load components in the longitudinal channel axis of HTA profiles are not admissible. Instead, HZA channels must be selected.

Dimensioning
HALFEN BOLTS
Observe load-bearing capacity of the profile! In case of a difference in the load-bearing capacity between the bolt and the HALFEN cast-in channel, use the smaller value
For profile HTA 28/15 with a channel Length L > 250 mm the bending moment of the bolt must be reduced to MRd = 42 Nm.
Changing bending stress: For facade veneers subjected to va-riable flexural stress conditions (e.g. due to temperature change), the alternating stress amplitude must not exceed a value of σA = ± 50 N/mm2 (=1,0) by the mean value σM, relative to the stressed cross section of the bolt.
For profile HTA 38/17 with a channel length L > 250 mm the bending moment of the bolt must be reduced to MRd = 101 Nm
Bending moment relative to the upper edge
of the profile or concrete. In case of flexure
and additional centric or diagonal tensile
stress the strain values must be added up: NEd ≤ FRd · (1 - MEd / MRd)
FRd = Load capacity design rating of the bolt
MRd = Design rating of the absorbable bending moment
NEd = Design rating of the existing tensile load component
MEd = Design rating of the existing bending moment

Construction specialists consider the HALFEN
handrail connections type HGB to be particularly well suited for fastening banisters on the front faces of thin deck and balcony slabs.
Fast and cost-effective
• adjustable anchoring• can be used even on thin front
faces of d ≥ 100 mm• bolts instead of welds or dowels • pre-engineered to reduce construction time• permits later adjustment and even simple replacement of all attached structures
Safe and dependable
• statically verified mounting• no damage to the concrete on the
visible front faces of the slab• while construction is in progress, it
can also serve to secure safety rails (note DIN EN 795 „Fall protection“)
• The associated high-strength HALFEN bolts ensure secure and statically solid attachment of the banister structure

HALFEN HANDRAIL CONNECTIONS HGB
Genera l
Balconies are a part of the structural system. "They must be designed, constructed, modified and maintained in such fashion that public safety or order and especially life, health or the natural fundamentals of life are not jeopardized". (MBO 07 and implementa-tion directives)
In this context, the technical rules established by public announcement as regulatory building codes must be observed.Technical rules specify load parame-ters, the calculation, dimensioning of structural products, construction types, structural layouts etc..
The individual federal states have established different building codes and regulati-ons. In all cases the technical regulations require verification of structural safety and functional fitness. The dimensioning of the banister mount must be backed up by a static calculation or a regulatory certification.
§ 4.2 (1) The contractor is required to perform the installation, at his own responsibi-lity, in accordance with the contract. He has to abide by the accepted standards of the art as well as the provisions of the law and regulatory directives. VOB Part B, § 4.3, requires the contractor to report to the customer, in writing, any obvious design flaws, which he, as the expert, must be able to recognize. He alone is responsible for any resulting defect and consequential expenses. If he has satisfied his reporting obligation, the responsibility for the defect (such as a frontal banister attachment into too thin a concrete slab) passes to the customer.
Accident Prevention Regulation “General Provisions” (VGB 1)Industrial Safety RegulationsETB – Directive “Fall Prevention Components”, version 1985Stainless Steels, certification No. Z-30.3-6, of April 20th, 2009DIN 1045-1: Support structures of concrete, reinforced concrete and prestressed concrete; design and constructionDIN 1055-3: Action on support structures - part 3; intrinsic load and superimposed loads for above-ground structuresDIN 1055-4: Action on support structures - part 4; wind loads DIN 18800-1: Steel structures; design and constructionDIN 18800-7: Steel structures; verification of weldability
A regulatory requirement as part of regional building codes refers to structural stability: "Every structure as a whole and in its individual components must be stably self-supporting". This stability must be statically verifiable on the basis of technical standards (here DIN 1055 Part 3+4).
Another regulatory requirement addresses traffic safety, for example: Balconies and loggias must have fall-preventing safety banisters when they border on an area that lies more than 1 meter below. Up to a drop height of 12m the minimum banister height is 0.90m from the top surface of
Regulations, standards and directives to be observed when constructing banisters:
the finished floor or accessible ledge. For drop heights greater than 12m (except as per German LBO´s) the banister must be 1.10m heigh.
Other regulations, not covered here, address the design, dimensioning, banister spacing, fire protection,thermal/sound insulation, and rainwater drainage.

Identifying the HALFEN HGB cast-in channels
Galvanised:Dipped in a galvanizing bath at a temperature of approx. 460°C, a method used primarily for open-profile channels.
Stainless Steel A4:Chromium is the most important alloying element in
stainless steel. A specific chromium concentration
ensures the generation of a passive layer on the
surface of the steel that protects the base material
against corrosion. This explains the high corrosion
resistance of stainless steel.
Product identification
• on channel side• additionally inside the profile
“Anchor channels of stainless steel may be employed outdoors – even in an industrial environment and near the ocean but may not be exposed to saltwater". refer to BVM directive “Metal banisters and balustrades”.

HALFEN HANDRAIL CONNECTIONS HGB
Dimensioning Fundamenta ls
The minimum height hb of a banister is 0.90 m from the top edge of the finished floor or accessible ledge to the upper edge of the banister/balust-rade. In the case of drop heights of more than 12.0 m (except as specified in the applicable regional building code (LBO)), the banister must be 1.10 m high.
It would be desirable to have one uniform minimum height of 1.00m as has already been mandated in the commercial sector and in some other European countries..
An attachment with anchor channels or dowel systems requires concrete at least of grade C 20/25. If the concrete is of less than agrade C 20/25 or it is unknown, a case-by-case decision must bemade.
The thickness of the balcony slab must be at least h = 100 - 150 mm(depending on channel profile according to german HGB approval) when the HGB is mounted on the front face. Other mounting types and systems require a thicker slab. All concrete-embedded mounts installed outdoors (e.g. on balconies) must consist of stainless steel.
The structural design of the banister must take all fundamental requirements into account. As a general rule, all banisters must be built in a way that a person cannot fall through them, for instance between rods, lattice bars or solid infill.They should also be designed so as not to entice but instead to discourage anyone from climbing over them.The specific requirements for a banister are determined by the intended use (private, public, commercial) and the drop height involved.Also to be observed are the building codes of the individual federal states, the ETB Directive “Fall Protection Components” and DIN 18065 (Stairs in Buildings – definition, rules, key measurements).
The forces bearing on the banister must be conducted into thestructural base. It will be necessary to verify that the forces a) are absorbed by the banister itself and b) can be transferred by the mounting elements into the deck slab.

3.2.2 Actions and required varificationsThe action forces HEd, VEd, MEd and the action moment NEd have to be determined according to the calculation basics of app. 7. The ratio between horizontal action and bending moment is limited acc. to the calculation basics to:
It has to be proofed that the design action value Ed is less or equal to the design resistance value Rd:
In the simplest case (permanent loads and variable loads are working in the same direction) the following equation for the design action value is valid:
In case of combined actions the following interactions have to be checked:
Ed ≤ Rd see table 3.1 and 3.2Ed = Design action value (NEd, VEd, MEd)Rd = Design resistance value (NRd, VRd, MRd)
Ed = G ⋅ Gk + Q ⋅ Qk
Gk; Qk = characteristic value of permanent load respectivly variable load acc. to local standards for load assumptionsG; Q = partial safety factors for permanent and variable action

Material / Corrosion protection
The HALFEN trapezoidal metal sheet mounting channelswere developed in cooperation with the industrial association for light-weight steel construction (IFBS).They consist of a C-shaped channel with at least two welded-on anchors, hot-dip galvanised or of stainless steel and have been approved by the German Construction Materials Supervisory Board.
Approval No. Z-21.4-84
The connecting elements for mounting between channel andsteel trapezoidal profile are considered IFBS-approved per general technical approval titled “Connections for use with structures employing cold profiles made of steel sheet”.
General
FV = Steel S235JR, hot-dip galvanisedA4 = Stainless steel 1.4571/1.4404/1.4401
Approval No. Z-14.1-4
Connecting elements: Stainless steel in concurrence with screw suppliers

Stainless steel A4:
Chromium is the important alloying element in stain-
less steel. A specific chromium concentration ensures
the generation of a passive layer on the surface of the
steel that protects the base material against corrosion.
This explains the high corrosion resistance of stainless
steel.

Recommended butt joint gap between two channels
The pre-finished channel type HTU is to be embedded in the concrete parts flush with the surface edge. It is advisable to level the concrete surface and to apply a slight slope to the outer edge of the concrete. This is to ensure that the trapezo-idal sheet metal rests only on the HTU channel. According to the german approval a heightened installation up to 5 mm is possible. If, on the other hand, the manufacturer of the tra-pezoidal sheet metal requires a total support width of more than 60 mm, this can be achieved through a flush channel installation and a flat concrete surface. A horizontal place-ment, properly aligned, and centred in the case of trusses of pre-stressed concrete, is to be ensured. Maintaining a20 mm butt joint gap between the individual channel ends is recommended.
The self-tapping screw is placed on the screw driver and is fastened in one step without predrilling a pilot hole. Even the 4-fold overlapping at joints does not pose a problem with the self-tapping screw.Use power screw drivers with approx. 1500 rpm and with a socket wrench, size 10.Suitable tools for the respective screws can be obtained from the screw supplier.The trapezoidal sheet metal must be attached in the central third of the channel back; The screw must be positioned at a minimum distance of 25 mm from the channel ends.

If the trapezoidal sheet metal mounting channels are attached in such fashion that the anchors of adjacent channels are offset from each other by at least 200 mm, the interaxial spacing aa may be reduced to 80 mm.
With less than full utilisation of the maximum impart FEd
as per above table, the edge distance ar may be reduced only in case of a sole central tensile stress NEd, to:
Prev. NEd = design rating per previous impact
max. FEd = maximum impact as per above table
With full utilisation of the maximum impact FEd
as per above table, the last anchor must be at least 100 mm from the component edge.
With full utilisation of the maximum impact FEd
as per above table, the “terminating anchors” must be at a min. distance of 150mm from one another
Determined by the geometry of the anchors and the required concrete covering.
Minimum component width with a one-channel layout.
In cases of transverse stress (VxEd , VyEd), the edge distances must not be reduced.

In modern wood construction, rafter shoes type HSF 6/12 are used to absorb the horizontal forces of rafter and collar beam roofs.
The Advantages at a Glance:
• Minimal planning effort, simply specify the profile and location of the HALFEN channels to be embedded in the concrete.
• Clear static conditions through flexible mounting of the rafter shoe. Type-tested statics, Test report No. 1. P
30 - 201/82, No. II B 3 - 543 - 506 Extension report.• No need for labour-intensive support constructions.• Simple and problem-free erection of the roof structure:
a) Rotatable arrangement of the support plate,b) Movable nailing brackets for vertical anchoring
for different rafter widths from 0 to 120 mm.c) Adjustable in the longitudinal rafter direction ± 15 mm.• Adjustable in the longitudinal channel direction of HALFEN
channels, allowing for different rafter spacings without special additional provisions.
• Excellent corrosion protection through hot-dip galvanisati-on
The distribution of the horizontal forces into the concrete structure occurs via officially approved HALFEN cast-in chan-nels type HTA.During assembly, ensure that the serration of the counter pla-te engages in the base plate. The marking slot on the counter plate must be oriented perpendicular to the direction of the slot in the elongated hole.
The maximum normal rafter strength is limited by the dimensioning of the individual rafter shoe parts. Load tests showed an average breaking load of 50 kN. With normal strengths that are greater than the recommended load capacity (= about 1/3 of the breaking load), the rafter spacing may need to be reduced, if required.
The minimum edge distance ar of the HALFEN cast-in channels can be reduced with lower loads, see table page 23. The distance to the
outer concrete edge must be at least 170 mm. It must be ensured that the HALFEN cast-in channels are installed
flush with the concrete surface.

When erecting the brick wall, the HAL-FEN brick tie anchors are inserted in the brick tie channels at any desired location or at recommended distances and after a 90° rotation pushed into the grouting space mortar for anchoring.
HALFEN brick tie anchor systems areefficient and proven mounting systems for attaching brick work, infills, partitions, facings (with and without air gap and/or heat insulation) using HALFEN brick tie anchors ML or BL to concrete walls and

Statically required attachments of load-bearing, room-enclosing solid walls can be designed with HALFEN brick tie channels as firewalls according to DIN 4102 T4 Chapter 4.8 as well. Anchoring to the adjacent components (steel reinforcedconcrete support, wall) fulfils the requirements for fire conditions with regard to stability and fire resistance rating, if it conforms to the standards of DIN 4102 T4 Para. 4.8.4
Attachment of a load bearing solid wall as a firewall accor-ding to DIN 4102 T4 Para. 4.8.4 (Pic. 20.2)
Explanations, DIN regulations
Insulation layer: According to DIN 4102 T4 Line. 4.5.2.6 insulation layers in connecting joint gaps must „[...] consist of mineral fibre according to DIN 18165 T.2/07.91, Section 2.2, must be of building material class A, have a melting point ≥ 1000°C according to DIN 4102 T. 17 and exhibit a gross density of ≥ 30 kg/m³ [...]“.
Masonry: Bricks (gross density class) and minimum thick-ness d according to DIN 4102 T4, Section 4.8.3, Table 45.
Note:HALFEN cast-in channels HTA and HZA Dynagrip along with HALFEN bolts are allowed for use in fire-exposed com-ponents. The permissible loads for the HALFEN channels are determined based on the bolt dimensions for a fire resistance rating of 60 minutes (F60) and 90 minutes (F90) according to technical approval. (see Certification Z-21.4-34 for HALFEN cast-in channels HTA and Certification Z-21.4-1691 for HALFEN cast-in channels HZA Dynagrip).
Product information
HALFEN brick tie anchors can be used at any desired position across the total length of the brick tie channel. As a rule, anchor spacing is 250 mm (4 anchors per meter).

Advantages:• The 92° angle ensures a tight fit to the formwork. Thus,
connection with the concrete is achieved and leakage of concrete slurry between the formwork and the corner profile is avoided.
• The U-shaped concrete-reinforced anchors do not interfere with the corner reinforcement and facilitate the assembly of the reinforcement cage.
• The concrete-reinforced anchors guarantee optimal anchoring.
• Low price due to serial production.

HALFEN CURTAIN WALL SUPPORT SYSTEMS HCW
Genera l
HALFEN Curtain wall system
This principle of construction is characterized by an outer wall with a continuous outer skin (see Fig. 1)
The curtain wall façade is to protect the interior of a building from external, undesirable environmental influences and yet, if desired, permit eye-contact with the outside through structural components that can be opened and/or are transparent. Specifically, this
In principle, one distinguishes between two construction methods of curtain wall façades: the post and beamfaçade and the modular façade.
One basic differentiating characteristic is the way the expansions within the façade are taken up. The first possibili-ty, known by the term post and beam façade (see Figure 2) is that the vertical and horizontal frame profiles are lined up in a straight line in practical production lengths, e.g., floor-to-ceiling and segment--wide. They are installed such that their longitudinal and trans-verse ends are kept slightly shorter, thus leaving room for a gap correspon-ding to the necessary expansion. The longitudinal and transverse connec-tions are constructed in a moveable fashion. The filler element (glass or panel) installed in this post and beam structure floats so-to-speak, and allows for an expansion within the scope of the installation clearance that was left open. The glass and filler elements are delivered separately and are not installed until they are at the construc-tion site, necessitating construction site scaffolding. With the second construc-
tion method, the modular façade, (see Figure 3), the façade is made of ele-ments prefabricated in the workshop, with glass, natural stone and panels already integrated. For taking up the expansions, the façade profiles are indi-vidually telescoped into one another in mazelike fashion.This method of construction allows
the façade contractor to begin with the interior work on the respective floor immediately after hanging a completely prefabricated module, since a driving-rain protection is ensured.In general, scaffolding is not required with this method of construction.
means sufficient stability against wind loads as well as enough insulating ability against frost in winter, the heat in summer as well as against external noise pollution.In addition, certain requirements must be met in the event of a fire and other disaster.

HALFEN Cas t - in Channel HCW 52/34
Channel load data
Assoc iated HALFEN bol ts HS 50/30
Depending on the load size, we recommend the use of HALFEN bolts HS 50/30 M16 and/or M20, grade 8.8 in combination with the HALFEN cast-in channel HCW 52/34. The bolt sizes mentioned below are manufactured in galvani-sed design with a special coating. For interior use this design
is considered equivalent to a hot-dip galvanised design. Other bolt sizes and materials can be supplied. Please contact us for detailed information.
Displacement r [mm] in load direction Fres.
Fres, ultimate = 150 kN
Load deformation diagram
Load Fres.
1st crack appearing in the concrete
The following average ultimate loads were determined from three tests:
The adjacent load deformation diagram may be used to determine allowable loads based on acceptable displacement and the required safety factor according to local building codes. The diagram is based on the following:• Tensile and transverse loads were increased at a ratio of 1:3 up to
the breaking point.• Concrete slab thickness ≥ 125 mm and reinforcement as shown on
previous slab.• Concrete strength class ≥ C 20/25 N/mm².• The load is transferred into the channel via two HALFEN bolts HS
50/30 M20 Grade 8.8. The bolt spacing is 150 mm. A sample calculation is shown below. The safety factor is chosen arbitrarily. However, the actual factors to be used must be analyzed based on general project-specifi c conditions or building regulations in eff ect.
Calculation example: Assumed safety factor ν = 3 (ultimate test load / working load) Average ultimate load from the tests:Transverse tensile stress FV ultimate = 142.3 kNTensile stress FN ultimate = 47.4 kNRes. diagonal tensile load Fres,ultimate = 150.0 kN
Actual working loads at the bolts (specification by façade stress ana-lyst): Transverse tensile stress FV = 35 kN Tensile stress FN = 10 kN
Perm. load with ν = 3 against average ultimate load from the tests: perm. FV = 142.3 / 3 = 47.4 kN perm. FN = 47.4 / 3 = 15.8 kN perm. Fres = 150 / 3 = 50.0 kN
Control: Working load FV = 35 kN < 47.4 kN Working load FN = 10 kN < 15.8 kN Working load Fres = = 36.4 kN < 50 kN
Displacement at working load < 1 mm (s. diagram).Actual safety factor for average ultimate load 1 = (150 / 36.4) = 4.12
FV ultimate = 142.3 kN
FN ultimate = 47.4 kN
FRes,ultimate = = 150.0 kN

HALFEN CURTAIN WALL SUPPORT SYSTEMS
Edge of S lab Brackets HCW-ED
Appl icat ion example
HALFEN Edge of slab brackets are connected in pairs to eit-her side of the mullion and are available in two types:• Type HCW-ED brackets are designed to support both
vertical and horizontal loads.• Type HCW-EW brackets are designed to support
horizontal wind loads only.
The brackets ensure a convenient adjustability of the attach-ment.The HALFEN bolts (fastening of the bracket to theHALFEN cast-in channel) and the regular hexagonal bolts M12,(fastening of the bracket to the façade pillar) should be of the strength grade 8.8. A round auxiliary hole in the long leg of the brackets serves the temporary attachment - e.g. by means of self-tapping screws to the pillar- until the actual connection is established.
The brackets are made of high-quality aluminium material.Special nylon discs are placed between bracket and pillar at the "Wind load" - Bracket HCW-EW to reduce the friction.
bolt distance
To guarantee a correct assembly, the HCW-ED brackets are marked ‘R” for right, ‘L’ for left and ‘UP’ for above.

Design Loads us ing two HCW-EW Brackets , Forces in the HALFEN Bol ts
Calcu lat ion bas isDes ign wind loads Type HCW-EW
The components of the design reaction forces in the HALFEN bolts at the connection location Curtain wall - bracket and HALFEN cast-in channel are calculated by multiply-ing the design loads Fvd and Fhd at the connection location curtain wall – bracket and façade post with the factors sx, sy and sz. The factors are dependent on the bracket geometry, the load direction and the bolt position. (see Fig. to the right). The following table shows the multiplication factors for determining the design -reaction forces in the HALFEN bolts.
Defi nition of the loads at the -bracket / post connection-bracket / channel connection
Lower mounting position of the HALFEN bolt(Position 3)
Given: slab thickness = 200 mm, width of mullion = 80 mm
projection a = 80 mm → p. 73 Design dead load Fvd = + 3.5 kN Design wind load (wind suction) Fhd = + 7.0 kN
Selected: HALFEN Bracket Type HCW-ED 2 possible projection M = 82 ± 25 mm
Interaction diagram Type HCW-ED 2 (→ p. 74) shows that the given loading is within the permitted load interaction area
Determination of the design reaction forces in a HALFEN bolt Lower mounting position (Position 3) Sx = (3.5/2) × 0.5 + (7/2) × (-0.5) = - 0.88 kN Sy = (3.5/2) × 3.6 + (7/2) × 1.0 = + 9.80 kN Sz = (3.5/2) × (-1.0) + 0 = - 1.75 kN
