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 />

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 />
