HALFEN FK4 brickwork supports transfer the dead load of the outer brick veneer

to the building’s load-bearing structure: an efficient construction principle developed with the experience of over 80 years of lasting technology.

adjustabilityHALFEN FK4 brickwork supports

provide continuous height adjustment of

+/- 13/8” which compensates for existing

tolerances of the structure as well as

installation inaccuracies of wall anchors.

Structural efficiencyFrom load capacities starting at

785 lbs up to 2,360 lbs, the HALFEN

FK4 brickwork supports allow efficient

anchoring of brickwork facades in

combination with HALFEN cast-in

channels.

Masonry has a New edge.and it’s called HaLFeN FK4.

Introducing a new adjustable shelf angle with a thermal break.

Reduced Thermal BridgingThe HALFEN FK4 brickwork supports are

offset from the edge of slab allowing

insulation to pass behind. Minimal contact

with the building structure means reduced

thermal bridging and lower energy loss.

QualityBy using HALFEN FK4 brickwork supports,

you profit from an approved anchoring

system, excellent adjustment options and

a complete product program covering all

aspects of brickwork facade.

efficient design As the demand for higher energy efficiency in

commercial buildings continues to increase,

the cavity between the brick veneer and the

substrate is getting larger to allow for more

insulation and air space. Along with this

increased cavity size, the traditional masonry

shelf angle, used to support the brick veneer

at the slab edge, is also getting larger and

subsequently heavier and more expensive to

install. Architects & engineers are looking for a

more efficient support solution. HALFEN FK4

brickwork supports use a thinner, light weight

shelf angle, eliminating brick notching while

also allowing for a wider cavity.

Sys tem components

The HALFEN FK4 brickwork support sy-stem is available in standard and custom con figurations to provide greater design flexibility for brick facades. Innovative engineering principles are used to pro-vide a safe and effective support system, while reducing thermal bridging and providing the contractor with an easy to install, adjustable solution. It is par-ticularly suitable for projects using wide, highly insulated air spaces behind the brick facade. The system is available in

both galvanized carbon, and stainless steel.

The FK4 support bracket assembly consists of one or more adjustable hangers welded to a support angle, and is supplied complete with adjuster plates and U-washers.

The fastest and most adjustable method of anchoring the FK4 system to concrete is to use of HALFEN cast-in anchor

chan nels and T-bolts. Post drilled anchors are also possible, but will limit horizontal adjustment and may damage the concrete structure and its reinforcement.

For adjustable connection to struc tural steel components, HALFEN channel without anchors can be surface welded to the structure.

Resul tant Loads f rom Masonr y Suppor t

The loads acting on HALFEN support brackets and their connections

to the concrete are determined by:

▪ The brick size

▪ The weight of brickwork to be supported

▪ The cavity (air gap) ‘a’ (see drawing)

▪ The bearing depth ‘z min’ (see drawing)

▪ The spacing of HALFEN support brackets

▪ Concrete dimensions and compression strength

It is important that this information is provided to HALFEN engineers

so the correct HALFEN support brackets can be offered. The tension

(T), shear (S), and resultant (R) loads at the connection to the con crete

must be also checked relative to allowable loads of the connection.

If HALFEN channels are used this service is provided by HALFEN

engineers.

z min = x – {upward adjustment} b = d/2 + a

DL = weight of brickwork per connection

DL x (d/2 + a) R = S2 + T2

Z min

Seismic LoadsAny additional seismic loads should be provided to HALFEN engineers

so they can be accounted for when calculating loads applied to the

HALFEN support brackets and their connection to the structure.

HALFEN HFA Fleming Anchors can be used to support horizontal

loads.

Wind & Impact LoadsHALFEN support brackets are designed to support the dead load of

the facade only. Wind loads or any impact loads on the facade must

be supported by independent ties to the structure designed by the

structural engineer.

differential MovementMovement joints are normally located immediately under support

levels. It is important that the architect and structural engineer design

the joint for adequate movement to prevent cracking in the facade.

Insulation and Thermal BridgingWider cavities containing greater thicknesses of insulating material

will better insulate against energy loss than traditional un-insulated

narrower cavities. Connections between the facade and the structure

make a thermal bridge between the living area and the exterior. To

minimize energy loss, it is important to mini mize the contact between

the facade and the structure while maintaining structural stability.

Materials also play a significant role. For example, stainless steel is

very much less thermally conductive than carbon steel.

Sta in less s tee l suppor t brackets

The HK4 / FK4 - system is a high integrity steel product. The system is available in both, galvanized carbon steel (FK4) and stainless steel (HK4).

Stainless steel offers many advantages to the specifier:

▪ Excellent corrosion resistance

▪ Resistance to unsightly staining

▪ Life-cycle costing benefits

▪ Lower heat transfer and thus reduced loss of thermal energy

through the building shell

▪ Aesthetic surface finish

▪ 60 % recycled content

▪ 100 % recyclable

Life-cycle costing is increasingly recognized as the true way to es-

tablish the cost of building components. The use of stainless steel

means no costly remedial or refurbishment measures are required

during the life of the structure.

As the trend to higher specification and longer service life conti-

nues, stainless steel will provide cost-effective long term solutions

to specifiers’ problems.

excellent corrosion resistanceHK4 is produced from Grade 316 stainless steel, which is recommen-

ded for highly corrosive areas such as marine locations or heavily

polluted industrial environments. The lifetime of the stainless steel

element is expected to be twice that of the galvanized material.

Resistance to unsightly staining

Life-cycle costing benefits If exposed, for example as a lintel, galvanized steel has to be re-

primed and refinished periodically, adding unnecessary mainte-

nance costs for the life of the building.

Lower heat transfer The heat conductivity coefficient of stainless steel is 40 % lower

than that of carbon steel. This leads to lower heat transmission and

thus to a smaller release of carbon dioxide from burning fossil fuels

used to heat and cool the building.

RecyclingStainless steel is 100 % recyclable. When a product finally reaches

the end of its long service life, it remains a valuable resource. This

helps the environment.

engineered brickwork support systems provide hidden support for brick soffits.

Virtually any flat or radiused masonry opening can be built without exposed steel using the HALFEN Adjustable Concealed Lintel System (HCL). Commercial, government, institutional, religious and high-end residential projects can now have all brick soffit masonry openings that are aesthetically pleasing and maintenance free.

HALFEN’s technical department uses the architect’s conceptual design to engineer a brick lintel support system for each specific opening. Unlimited combinations using different brick size, span, coursing, soffit depth and arch geometry can be designed and manufactured to meet project specifications.

additional advantages:

• Unlimited span and soffit width can be achieved, with connection (s) to the structure

• Available in hot-dip galvanized or stainless steel

The HALFEN HFA Fleming Anchor System is used to restrain exterior masonry facades that are subjected to both wind and seismic loads. The system consists of the Fleming Anchor Chan-nel, which is secured to the substrate; and the Fleming Anchor, one end of which is inserted into the channel. The other end of the Fleming Anchor is bonded into the facade's horizontal mortar bed which is also reinforced with wire. Once installed the system components efficiently transfer both positive and negative facade loads to the substrate.

Quality Features: • Fleming Anchor Channels are roll formed from 22 gage

(0.85 mm) galvanized steel strip. The channel dimensions are 1”x21/32” (25 mm x 17 mm).

• Fleming Anchors are T-shaped and are stamped from 14 gage (1.9 mm) galvanized steel strip, complete with a cen-tral stiffening rib and two tabs.
