HALFEN Curtain wall system
Modern structures often demand high performance façades that can be reliably installed in a minimum time period to meet compressed construction schedules. Today, curtain wall façades are one of the façade systems Today, increasingly selected by designers and clients. The Curtain wall can comprise of glass, metal or stone elements supported by a steel or aluminium frame. The frame is either factory-assembled factoryassembled with the façade elements to form a panel, or is put together at the construction cons truction site. To maximise the effi ciency and an d reliability reliabilit y of installation insta llation,, HALFEN channels and T-bolts are often selected as the preferred connection method between the façade and the building structure.

HALFEN CURTAIN WALL SUPPORT SYSTEMS Installation methods for HALFEN Cast-in channels
Typical installation
HALFEN channels can be installed using several methods to suit the type of structure and concrete formwork. A typical installation sequence is shown below.
Nail channel to formwork.
When concrete is set, remove the formwork, then remove the filler material from the channel.
Insert T-bolt into channel and rotate ninety degrees.
Attach component adjust and tighten nut. Combined with slotted brackets the HALFEN channel allows 2 or 3-way adjustment for curtain wall components.
When the HALFEN channel is installed to the top of the floor slab, it is not possible to nail the HALFEN channel to the formwork as shown in the first installation photograph above. Other methods are used which are illustrated below. Nail through nail holes in HTA channel Wooden batten nailed or screwed to edge formwork

HALFEN CURTAIN WALL SUPPORT SYSTEMS Installation methods for HALFEN Cast-in channels
Corner and edge installation
Façades often require multiple connections or connections close to corners and concrete edges. HALFEN provides product design assistance to ensure that loads are effi ciently transferred into the structure and that channels can be accurately placed. Welded Corner Assembly Factory fabricated assembly allows bolt fixings close to corner edge. Additional spacer straps may be added to ensure correct channel height.
Fabricated Channel Pair Factory manufactured to provide accurate channel spacing.
Nail channel securely to formwork
Fabricated Ski Assembly Factory fabricated assembly assures channel positioning on top of metal deck ribs & from slab edge.
Special Anchor Fabrications to allow positioning and fixing of channel to troughs in metal deck.
Edge connections to thin floor slabs using permanent metal formwork can be achieved using HALFEN Pours top which uses HALFEN HTA or HTA-R channels factory installed to permanent metal formwork.
HALFEN Pourstop is installed in short or long lengths to the edge of the floor slab.
Typical pourstop assembly, designed to suit slab dimensions and load requirements.
Special corner assembly designed for high loads.

HALFEN CURTAIN WALL SUPPORT SYSTEMS Advantages of the HALFEN Channel system
HALFEN Channel
• Only simple tools needed for installation. • Easy and fast to install without special training. • Components protected from corrosion by quality galvanising and plating. • Can be installed without power supply. • Easily adjustable connections. • Fully tested components with verified load capacities. • Installation is easy to visually check
The only tool required.
10
HALFEN CURTAIN WALL SUPPORT SYSTEMS Advantages of the HALFEN Channel system compared to drilled and welded connections
Drilled bolts
• Power tools produce vibration, noise, and dust → operator safety hazards and reduced available installation time. • Drilling and expansion forces from installed bolts risk damaging concrete and reinforcement → higher risk and potentially high repair costs. • Quality of installation is difficult to check on site (depth of hole, diameter of hole, torque critical) → higher risk • Drilling needs a lot of time and bolt installation should be tested to verify quality → slower installation • Heavy electrical equipment, trailing wires and electricity → safety hazards. • New holes have to be drilled if adjustment is needed after the initial installation → slower installation.
Welding
• Risk of sparks starting fires and damaging glass & aluminium façade → high risk and high cost. • Quality welding difficult to achieve and check on site → high risk. • Welding needs a lot of time and should be tested to verify quality → slow installation and high risk. • Heavy electrical equipment, trailing wires and electricity → safety hazards. • Welds must be broken and re-welded if adjustment needed after initial installation → slow installation. • Embedded plates are designed per project and need testing to verify performance. • Painting required after welding to provide any corrosion protection → poor corrosion protection, more time, another operation to check, dripping paint damages façade and creates health hazard.
Welding requires diffi cult repositioning of heavy equipment and a costly energy supply.
Vibration also can cause permanent health damage.
Welding is slow, is a fire risk, and needs to be closely checked for quality.

Channel load data A series of 3 tests produced the following average ultimate loads:
Load deformation diagram
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: • The concrete slab is ≥ 125 mm thick and reinforced according to the diagram on the previous page. • Concrete compression strength ≥ C 20/25 N/mm² (c ylinder/ cube) with normal weight aggregate. • Load is equally distributed to the channel by two HALFEN T-bolts (ordered separately) spaced at ≥ 150 mm centers. See below for sizes and load capacities. An example of a typical calculation method is shown below. The factors used in the calculation example are for illustration only. Actual factors used on a project basis must be checked according to local or national building regulations. Also the calculations make no allowance for load magnification due to load eccentricities. These must be included according to the project design of the connection. Contact us for guidance if required. Calculation Example: Assumed safety factor 3 applied to the ultimate test load.

Fastener information HALFEN T-bolts type HS 50/30 8.8 grade, M16 and M20 are recommended for use with HALFEN channel type HCW 52/34 according to the load performance required. The loads FS allow. shown in the table below are per bolt and based on applied safety factors of approximately 2.5 : 1, other factors may be applied according to appropriate regula-
tions and project requirements. Please note, that fastener performance may be limited by channel capacity. The sizes shown are produced with a special coating equivalent to hot dip galvanising in salt spray tests. T-bolts in other sizes and materials are available if required, please contact us for details.

Notes: Self drilled fasteners and the structure must be capable of supporting the loads imposed. Fasteners should be positioned in the central third of the rail width, and no closer than 25mm to the end of the channel. For pure tensile loads edge distances may be reduced to a minimum of 50mm with a corresponding reduction in allowable load according to the formula: Reduced ar = (Reduced load x ar) / recommended load. Further design information is available in HALFEN catalogue B-E.

H A L F E N C U R T A I N WA L L S U P P O R T S Y S T E M S Edge of slab brackets HCW-ED / -EW
Application example
HALFEN Edge of slab brackets are connected in pairs to either side of the mullion and are available in two types: • HCW-ED brackets are designed to support both vertical and horizontal loads. • HCW-EW brackets are designed to support horizontal wind loads only.
bolt distance
The brackets provide convenient connection adjustment. T-head bolts M12 grade 8.8 connections are required to the mullion and cast-in channel. Pilot holes are also provided in the bracket if it is preferred to temporarily position the bracket prior to drilling the mullion for the main connection. The brackets are manufactured from high strength aluminium. Nylatron shims are available as low-friction shims for windload brackets. HCW-ED brackets are marked ‘R’ (right) and ‘L’ (left) with ‘UP’ at the top. Care should be taken to orientate the brackets correctly to avoid overloading the connections.

Forces acting on the T-head bolts at the channel To get the design action on the HALFEN T-head bolt connecting HALFEN Curtain wall bracket and HALFEN channel, the design loads Fvd and Fhd at the connection between curtain wall bracket and façade mullion can be multiplied with the factors Sx, Sy and Sz. These factors depend on the bracket´s geometry, on the load direction and on the position of the bolt (see drawings right). The following tables show the multiplication factors for determination of the forces at the channel bolt to calculate with.

Selected:
slab thickness = 20 cm, width of mullion = 80 mm projection a = 80 mm ( → p. 28, calculation basis) design deadload F vd = + 3.5 kN design windload (suction) Fhd = + 7.0 kN
top bolt position (position 1) Sx = (3.5/2) × 0.6 + (7/2) × (-0.5) = Sy = (3.5/2) × 1.6 + (7/2) × 3.1 = Sz = (3.5/2) × (-1.0) + 0 =
HALFEN bracket type HCW-ED 2 OK ⇒ possible projection M = 82 ± 25 mm ⇒ interaction diagram type HCW-ED 2 (see → p. 28) shows that the given loading is within the permitted load interaction area OK
⇒ resultant bolt load
Determination of forces at each HALFEN T-head bolt bottom bolt 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
- 0.70 kN + 13.65 kN - 1.75 kN
