Shear Load Connectors

Swann Direct is an approved supplier of Leviat’s Ancon Shear Load Connectors, which offer significant advantages over plain dowel bars. They are more effective at transferring load and accommodating movement and, due to their two-part construction, are more simple to install.

The sleeve component is nailed to the formwork and cast in with the first pour; drilling of either formwork or concrete is not required. Once the formwork is removed, the dowel component is pushed into the sleeve and cast-in with the second pour.

Leviat’s Ancon Shear Load Connectors also include solutions for suspended and ground bearing concrete slabs.

The Ancon E-HLD from Leviat allows the connection of new slabs to diaphragm walls or secant pile walls in basement construction. The dowel component is resin-fixed in the wall.

Ancon E-HLD

The Ancon Staisil from Leviat is designed to transfer shear loads and limit sound transmission across joints in concrete. The sleeve contains sound absorbing material between two stainless steel tubes.

The Ancon DSD from Leviat is the original two-part, double dowel, shear load connector. The two dowels are Duplex stainless steel bar. The dowel component can move longitudinally within the sleeve to accommodate movement.

The connector is available in ten standard sizes and has design capacities from around 20kN to over 950kN. The larger connectors can be used in joints up to 60mm wide. Larger joints can be accommodated using special dowels.

DSD Shear Load Connector

The Ancon DSDQ shear load connector from Leviat, uses the same dowel component as the Ancon DSD, but the cylindrical sleeve is contained within a rectangular box section to allow lateral movement in addition to the longitudinal movement.

There are nine standard sizes which have design capacities from around 30kN to over 950kN. A range of stainless steel single dowel shear connectors is also available.

DSDQ Shear Load Connector

The ED is a low cost dowel connector for use in floor slabs where alignment is important but loads are small. The single dowel shear connector is available in four sizes with each size available in two lengths.

ED Connector

The ESD is a single dowel shear connector and is available in four sizes with each size available in two lengths. Leviat’s Ancon ESD shear connectors are used where the slab or wall is too thin for Ancon DSD, and where loads are small.

ESD Shear Connector

The ESDQ shear load connector uses the same dowel as Leviat’s Ancon ESD, but the cylindrical sleeve is contained within a rectangular box section to allow lateral movement in addition to longitudinal movement.

ESDQ Shear Load Connector

The ESDQ-L Lockable Dowel allows initial movement to take place and then, after a predetermined time period (generally 60-120 days), is locked with a two-part epoxy resin poured into the L-shaped grout box.

ESDQ-L20 Lockable Dowel

The dowel component is manufactured from 30mm diameter Duplex stainless steel, but is shorter than the ESDQ-L20 dowel.

One end of the dowel is designed to fix into the Leviat stainless steel Ancon SKS24 Threaded Anchor cast into the face of the concrete, and the other end features a series of grooves to accept the Locking Plate. The sleeve component is the same as used in the ESDQ-L20.

ESDQ-L20W Lockable Dowel

The Ancon HLD from Leviat is a two-part, high load, shear connector. The dowel component moves longitudinally within the sleeve to accommodate movement. The connector is available in seven sizes with design capacities from 24kN to over 500kN.

HLD Shear Connector

The Ancon HLDQ, high load shear connector from Leviat, uses the same dowel component as the Ancon HLD, but the cylindrical sleeve is contained within a rectangular box section.

This sleeve allows lateral movement or rotation in addition to longitudinal movement. The connector is available in seven sizes with design capacities from 24kN to over 500kN.

HLDQ High Load Shear Connector

The HLDQ-L30 is a high load Lockable Dowel with a design capacity of up to 136kN.
