Range of Shear Load Connectors
Leviat’s range of Ancon shear connectors offers significant advantages over plain dowel bars. These Shear Connectors are more effective at transferring load and accommodating movement, and are more simple to install.

The DSD is the original two-part, double dowel, shear load connector. The dowel component can move longitudinally within the sleeve to accommodate movement. The connector is available in ten standard sizes and can transfer design loads from around 20kN to over 950kN. The larger connectors can be used in joints up to 60mm wide.
The DSDQ shear load connector 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. Nine standard sizes can be used to transfer design loads from around 30kN to over 950kN.
The Ancon HLD 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.
The Ancon HLDQ, high load shear connector 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.
The ESD is a single dowel shear connector and is available in four sizes with each size available in two lengths. Ancon ESD shear connectors are used where the slab or wall is too thin for Ancon DSD, and where loads are small.
The ESDQ shear load connector uses the same dowel as the Ancon ESD, but the cylindrical sleeve is contained within a rectangular box section to allow lateral movement in addition to longitudinal movement.
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.
Ancon Staisil-HLD Acoustic Dowel
The Ancon Staisil-HLD Acoustic Dowel is designed to dampen impact noise in multi-storey developments by decoupling concrete components such as stair landings. The 22mm diameter stainless steel dowel bar is located in a sound absorbing sleeve.
The Ancon E-HLD 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.
Solutions for Post-Tensioned Concrete Frames
Ancon ESDQ-L20 Lockable Dowel
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.
Ancon HLDQ-L30 Lockable Dowel
The HLDQ-L30 is a high load Lockable Dowel with a design capacity of up to 136kN.
Ancon ESDQ-L20W 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 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.
Ancon ALP Locking Pin
The pin component is manufactured from grade 500 coil bar which comprises a constant rolled thread. One end of the pin features a hot forged head and the other end features a notch to accept the Ancon locking plate. The sleeve allows lateral and some rotational movement of the pin, in addition to longitudinal movement, prior to locking. The sleeve features the standard Ancon void former. A blue lid allows easy identification on site, differentiating it from a Lockable Dowel in a cast slab.
Ancon ALP-W Locking Pin
For walls, the pin component is manufactured from grade 500 coil bar like in the slab-to-slab system but is shorter in length. One end of the pin screws directly into a coil threaded anchor (product ref. ALP19TA) that is cast into the face of the concrete wall and the other end features a notch to accept the proprietary Locking Plate. The sleeve component is the same as used in the standard slab-to-slab ALP system.
Designed to minimise thermal bridging in masonry cavity walls, the patented Ancon Thermal Windpost (TWP2) from Leviat offers up to an impressive 70% reduction in thermal transmission through the span of the windpost.
