for the Construction Industry
Ancon designs and manufactures high integrity steel products for<br />
the construction industry. Through continuous programmes of<br />
new product development, inward investment and employee<br />
advancement, the company is committed to maintaining the<br />
highest level of customer service within a dynamic and<br />
challenging industry.<br />

Reinforced concrete is an important<br />
construction material. It offers strength,<br />
durability and can be formed into a variety of<br />
shapes. Concrete structures are designed with<br />
expansion and contraction joints at appropriate<br />
places to allow movement to take place. The<br />
design of the joint is important for the overall<br />
design to function correctly.<br />
Ancon shear load connectors offer significant<br />
advantages over conventional single dowels.<br />

ANCON SOLUTION TO JOINTS<br />
In most cases conventional dowelled or<br />
corbelled joints can be replaced by joints<br />
incorporating Ancon shear connectors. These<br />
are more effective at transferring load and<br />
allowing movement to take place, easier to fix<br />
on site and a far more cost effective solution.<br />
They can be used for movement joints in floor<br />
slabs, suspended slabs, and for replacing<br />
double columns and beams at structural<br />
movement joints. Applications in civil<br />
engineering include joints in bridge parapets,<br />
bridge abutments and diaphragm wall<br />
construction.<br />

ANCON SHEAR LOAD CONNECTORS<br />
The <strong>DSD</strong> range of connectors offers significant<br />
advantages over conventional single dowels.<br />
Each connector is a two-part assembly<br />
comprising a sleeve and a dowel component.<br />
Installation is a fast and accurate process,<br />
drilling of either formwork or concrete is not<br />
required. The sleeve is simply nailed to the<br />
formwork ensuring subsequent alignment with<br />
the dowel, essential for effective movement.<br />
They are manufactured from stainless steel to<br />
ensure a high degree of corrosion resistance<br />
with no requirement for additional protection.<br />
Free software is available from Ancon that<br />
simplifies the design of movement joints in<br />
reinforced concrete. For a given application,<br />
Ancon’s design program will calculate the size<br />
and quantity of shear load connectors<br />
required, the edge distance and spacings at<br />
which they should be installed, and details of<br />
the local reinforcement.<br />
Ancon <strong>DSD</strong> <strong>Shear</strong> <strong>Connectors</strong><br />
The Ancon <strong>DSD</strong> is the original two-part,<br />
double dowel, shear load connector. The<br />
dowel component can move longitudinally<br />
within the sleeve to accommodate movement.<br />
The connector is available in ten standard<br />
sizes and can transfer loads from around 20kN<br />
to over 450kN. The larger connectors can be<br />
used in joints up to 60mm wide. Larger joints<br />
can be accommodated using special dowels.<br />
Please contact Ancon’s Technical Department<br />
for further information.<br />
Ancon <strong>DSD</strong>Q <strong>Shear</strong> <strong>Connectors</strong><br />
The Ancon <strong>DSD</strong>Q shear load connector<br />
uses the same dowel component as the<br />
Ancon <strong>DSD</strong>, but the cylindrical sleeve is<br />
contained within a rectangular box section to<br />
allow lateral movement in addition to the<br />
longitudinal movement. Nine standard sizes<br />
can be used to transfer loads from around<br />
30kN to over 450kN.<br />

Ancon <strong>DSD</strong> and <strong>DSD</strong>Q connectors should be<br />
positioned in slabs and beams within the<br />
minimum dimensions shown in the table below<br />
to ensure full load transfer. For information on<br />
reduced spacings or edge distances please<br />
contact Ancon.<br />
For slabs or beams with a thickness greater<br />
than the standard, the values for standard<br />
thickness apply. For slabs and beams with a<br />

REINFORCEMENT<br />
Local Reinforcement<br />
Local reinforcement is required around each<br />
<strong>DSD</strong> dowel and sleeve component to bridge<br />
any fine cracks that develop in the concrete as<br />
the dowels transfer load. Correct detailing in<br />
accordance with BS 8110 and the<br />
recommendations provided here, will ensure<br />
the Ancon <strong>DSD</strong> and <strong>DSD</strong>Q shear connectors<br />
attain their full capacity.<br />

Beam Reinforcement<br />
The main consideration for beams is usually<br />
the design reinforcement to carry the shear<br />
load. This is provided in accordance with well<br />
established procedures set out in international<br />
codes, and will require shear links local to the<br />
Ancon <strong>DSD</strong> units.<br />
In addition to this reinforcement, particularly in<br />
thin beams, reinforcement must be added to<br />
prevent vertical splitting of the concrete. The<br />
reinforcement should be located as shown in<br />
the diagrams below.<br />

Reinforcement Continuity Systems<br />
Reinforcement Continuity Systems are an<br />
increasingly popular means of maintaining<br />
continuity of reinforcement at construction<br />
joints in concrete. The system eliminates the<br />
need to drill shuttering and can simplify<br />
formwork design, thereby accelerating the<br />
construction process. The Ancon Eazistrip is<br />
available in both standard units and special<br />
configurations.<br />
Reinforcing Bar Couplers<br />
The use of reinforcing bar couplers can<br />
provide significant advantages over lapped<br />
joints. Design and construction of the concrete<br />
can be simplified and the amount of<br />
reinforcement required can be reduced.<br />
Because the strength of a mechanical splice is<br />
independent of the concrete in which it is<br />
located, the joint can also remain unaffected<br />
by any loss of cover. The range includes<br />
threaded and mechanically bolted couplers.<br />
Punching <strong>Shear</strong> Reinforcement<br />
Used within a slab to provide additional<br />
reinforcement around columns, Ancon <strong>Shear</strong>fix<br />
is the ideal solution to the design and<br />
construction problems associated with<br />
punching shear. The system consists of<br />
double-headed studs welded to flat rails,<br />
positioned in a symmetrical pattern around the<br />
column head. The shear load from the slab is<br />
transferred through the studs into the column.<br />
Insulated Balcony <strong>Connectors</strong><br />
Ancon Isolan connectors join external concrete<br />
balconies to internal floor slabs. Used to<br />
minimise cold bridging, they provide continuity<br />
to the thermal insulation. Standard systems,<br />
comprising rigid CFC-free polystyrene insulation<br />
and duplex stainless steel shear reinforcement,<br />
suit most depths of free cantilever and propped<br />
cantilever balconies. Conventional reinforcing<br />
bars are used to provide the tension and<br />
compression reinforcement.<br />
Channels and Bolts for Fixings to Concrete<br />
Cast-in channels are used for fixing masonry<br />
support systems to the edges of concrete<br />
floors and beams. Channels are available in<br />
different sizes ranging from simple self<br />
anchoring channels for restraints, to large<br />
capacity channels with integral anchors.<br />
A selection of channels can also be supplied<br />
plain-backed for surface fixing. Expansion<br />
bolts, resin anchors and set screws in stainless<br />
steel complete the range of fixings.<br />
