ANCON SHEAR LOAD CONNECTORS

The Ancon rang e of shear load connectors

provides solutions for a w ide range of

ap plications, load s, slab dep ths and joint

thicknesses.

Each connector is a tw o-part assem bly

com prising a sleeve and a dow el com ponent.

The sleeve is nailed to the form w ork ensuring

subsequent alignm ent w ith the dow el. This

alignm ent is essential for effective m ovem ent.

The com plete installation procedure is show n

on page 8.

Ancon shear load connectors are

m anufactured from stainless steel to ensure a

high d egree of corrosion resistance w ith no

req uirem ent for ad ditional protection.

In addition, Ancon D SD /Q and ES D /Q

connectors can be provided w ith 90 m inutes

fire protection. Special sleeves, m anufactured

from a fire barrier m aterial, replace the

com pressible filler at the connectors position in

the joint. This m aterial foam s and exp andsduring a fire to protect the connector (page 18).

Ancon DSD Shear Connectors

The A ncon D SD is the original tw o-part,

double dow el, shear load connector. The

dow el com ponent can m ove longitudinally

w ithin the sleeve to accom m odate m ovem ent.

The connector is available in ten standard

sizes and can transfer loads from around 20 kN

to over 450kN . The larger connectors can be

used in joints up to 60m m w ide. Larger joints

can b e accom m odated using special dow els.

Please contact Ancons Technical D epartm entfor further inform ation.

Ancon DSDQ Shear Connectors

The A ncon D SD Q shear load connector

uses the sam e dow el com ponent as the

Ancon D SD , but the cylind rical sleeve is

contained w ithin a rectangular box section to

allow lateral m ovem ent in ad dition to the

longitudinal m ovem ent. N ine standard sizes

can be used to transfer loads from around

30kN to over 450kN .

CIVIL ENGINEERING APPLICATIONS

Movement Joints in Carriageways

Ancon D SD shear connectors are used in

carriag ew ay joints to transfer high shear load s

caused by traffic load ing and for elim inating

differential settlem ent.

Bridge Abutments

Ancon D SD shear connectors are used

vertically at bridge ab utm ents to fix the bridge

deck to the ab utm ent. In addition to ease of

installation, the use of Ancon D SD shear

connectors allow s for the bridge deck to be

jacked up for bearings to be replaced.

J oints in Parapets

The use of Ancon shear connectors in the

vertical joints in parapets is a sim ple and cost

effective w ay of connecting the sections.

The Ancon D SD Q facilitates significant rotation

at the joint w ithout red ucing the horizontal

shear capacity.

Diaphragm Wall/Slab Connections

C onnecting road slabs to diaphragm w alls can

be a difficult and expensive operation. Form ing

recesses, or using post fixed dow els into site

drilled holes presents m any problem s on site.

Ancon D SD shear connectors provide a costeffective solution. The sleeve com ponents are

nailed to plyw ood form w ork w hich is rigidly fixed

to the reinforcem ent cage. After excavation the

plyw ood is rem oved to reveal the faces of the

sleeves. The dow el com ponents can now be

inserted ready to support the slab.

Contiguous Piled Wall/Slab Connections

Sim ilar in application to diap hragm w all

construction, Ancon D SD shear connectors are

used to transfer shear load from slab to p ile.

The concrete m ust be able to sustain the load

transferred by the A nco n dow els w hen the

shuttering is struck. The follow ing table m ay be

used to estim ate the num ber of days after

w hich supp orting form w ork could be rem oved.

For exam ple, if the self w eight of a suspended

slab rep resents one half of its total designload , enter the Tab le w ith a factor of 0.5. From

this it can b e seen that G rade 15 concrete

w ould attain enough strength in 28 days to

support the self w eight of the slab. The

strength/tim e relationship of G rad e 30

concrete w ill show the num ber of days need ed

to achieve a strength of 15M Pa (typically less

than seven). The supporting form w ork could

therefore be safely rem oved after that num ber

of days. A qualified structural engineer should

advise.

1 2RECOMMENDATIONS FOR THE

INSTALLATION OF ANCON SHEAR

LOAD CONNECTORS

The tw o part design of all Ancon shear

connectors rem oves the need for drilling

form w ork on site, supporting do w el bars andfitting debonding sleeves and end caps. The

installation is a fast and accurate p rocess.

Fix the local reinforcem ent in p osition around

the sleeve com ponent together w ith any other

reinforcem ent that is req uired , ensuring that

the correct cover to the reinforcem ent is

m aintained. Pour the concrete to com plete the

installation of the sleeve com ponent.

Position the com pressible joint filler of the

ap propriate w idth for applications w here

m ovem ent is expected betw een the tw o

sections of concrete.

Push the dow el com ponent through the joint

filler (if ap plicable) until it is fully located in the

sleeve com ponent. It m ay be necessary to tap

the dow el com ponent to overcom e the dim ple

in the sleeve w hich pinch holds the dow el in

the sleeve and prevents dislocation w hen the

concrete is vibrated.

4 5

W hen the concrete has achieved sufficient

strength, strike the shuttering. Peel off or

puncture the Ancon label to reveal the holes for

the dow els. W here Ancon D SD Q or ES D Q are

being used, the label should only be punctured

enough to allow the dow els into the cylind rical

sleeve.

3

Fix the local reinforcem ent in position around the dow el com ponent together w ith any other

reinforcem ent that is req uired, ensuring that the correct cover to the reinforcem ent is m aintained.

Pour the concrete to com plete the installation of the Ancon shear connector.

Note:-

(i) Although installation is show n for Ancon D SD , the procedure is the sam e for all Ancon shear

connectors.

(ii) W here deep concrete pours are proposed, the installation w ill require further consideration. M ore

robust fixing of the sleeve and dow el com ponents w ill be necessary, to avoid displacem ent during

placing of the concrete.

Slab Thickness & Spacings

The m inim um slab and beam thicknesses are

show n for each type of Ancon shear

connector.

Spacings should be equal to or greater than

the m inim um show n for each type. For deeperslabs, w hen using D SD and D SD Q shear

connectors, the closer centres show n for

beam s can be adopted.

Design Joint Widths

To allow for site variations, the designer should

consider increasing the calculated joint w idth

by a factor of up to 1.3 to obtain the d esign

joint w idth, w hich is a m axim um .

Local Reinforcement &Cover

As high tensile stresses are generated at

dow el locations, sufficient local reinforcem ent

needs to b e includ ed to ensure full design

capacity is achieved . Form ulae for calculating

m inim um areas of local reinforcem ent areincluded on pages 12 and 13.

It is im portant that the correct cover to local

reinforcem ent around each Ancon D SD dow el

is achieved. M inim um cover is to the

recom m endations of B S 8110 P art 1 : 1997.

DOWELLED J OINTS

D ow els are used to transfer shear across

construction and m ovem ent joints in concrete.

They are usually either cast or drilled into the

concrete. A single row of short thick dow els

provides reasonable shear transfer but sufferfrom deform ation. This can lead to stress

concentrations, resulting in sub sequent

spalling of the concrete.

W here dow els are used across expansion and

contraction joints, half the length of the bar is

deb ond ed to allow m ovem ent to take place.

D ow elled joints either require form w ork to be

drilled for the dow els to pass through, or

concrete to b e drilled for dow els to b e resin

fixed in one side.

W here dow els are used at m ovem ent joints

the dow els w ill need to be accurately aligned

in both directions to ensure m ovem ent can

actually take place, otherw ise cracking is likely

to occur.

Sing le dow els are not very effective w hen

used across joints w ider than 10m m .

KEYED J OINTS

K eyed joints require com plicated form w ork to

create the tongue and groove. If the joint is

no t form ed correctly, differential m ovem ent

can take place. Load is transferred through

the locally red uced section of the joint w hichcan at tim es result in cracking.

Reinforcement Continuity Systems

R einforcem ent C ontinuity System s are an

increasingly popular m eans o f m aintaining

continuity of reinforcem ent at construction

joints in concrete. The system elim inates the

need to drill shuttering and can sim plify

form w ork design, thereby accelerating the

construction process. The A nco n K eybox is

availab le in both standard units and special

configurations.

Reinforcing Bar Couplers

The use of reinforcing b ar couplers can

provide significant advantages over lap ped

joints. D esign and construction of the concrete

can be sim plified and the am ount of

reinforcem ent required can be reduced.

B ecause the strength of a m echanical splice is

ind ependent of the concrete in w hich it is

located , the joint can also rem ain unaffected

by any loss of cover. The range includ es

threaded and m echanically bo lted couplers.

Punching Shear Reinforcement

U sed w ithin a slab to p rovide additional

reinforcem ent around colum ns, Ancon Shearfix

is the ideal solution to the d esign and

construction problem s associated w ith

punching shear. The system consists of

doub le-head ed stud s w elded to flat rails,positioned in a sym m etrical pattern around the

colum n head. The shear load from the slab is

transferred through the stud s into the co lum n.

Channels and Bolts for Fixings to Concrete

C ast-in channels are used for fixing m asonry

support system s to the edges of concrete

floors and b eam s. C hannels are available in

different sizes ranging from sim ple self

anchoring channels for restraints, to large

capacity channels w ith integral anchors.

A selection of channels can also be sup plied

plain-backed for surface fixing. Expansion

bolts, resin anchors and set screw s in stainless

steel com plete the range of fixings.

Special Fabrications

Ancon has a w ealth o f experience of w orking

w ith stainless steel and can produce special

fab rications to suit individual custom er

req uirem ents. Ancon supplies industries such

as civil and m arine engineering , w ater,

petrochem ical, m ining and foo d handling and

m aintains large stocks of stainless steel in

order to m eet urgent delivery requirem ents.
