Range of Shear Connectors

Ancon’s range of shear connectors offers significant advantages over conventional single dowels. These Shear Connectors are more effective at transferring load, simpler to install and ensure the necessary alignment required for movement.

Solutions for Suspended Slabs

Ancon DSD
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 loads from around 20kN to over 950kN. The larger connectors can be used in joints up to 60mm wide

Ancon DSDQ
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 loads from around 30kN to over 950kN.

Ancon ESD
The ESD is a single dowel shear connector and is available in four sizes. Ancon ESD shear connectors are used where the slab or wall is too thin for Ancon DSD, and where loads are small.

Ancon ESDQ
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 or rotation in addition to longitudinal movement.

Ancon ED
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. The sleeve component is made from a durable plastic and features an integral nail plate. The dowel component is Duplex stainless steel.

Ancon Staisil-HLD Acoustic Dowel
The Ancon Staisil-HLD Acoustic Dowel is designed to reduce the oscillation of impact sound through a building by isolating concrete components, such as stair landings from the main structural frame. The 22mm diameter stainless steel dowel bar is located in a sound absorbing sleeve.

Solutions for Post-Tensioned Concrete Frames

ESDQ-L20 Lockable Dowel
The ESDQ-L20 Lockable Dowel allows initial movement to take place and then, after a predetermined time period (generally 90-120 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 500MPa 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 500MPa coil bar like in the slab-to-slab system but is shorter in length. One end of the pin screws directly into a 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.

Solutions for Ground-Bearing Concrete Slabs

Ancon MultiJoint System
Ancon MultiJoint is an all-in-one solution to load transfer, concrete contraction, armoured edge protection and formwork. It is ideal for use in factories, warehouses, distribution centres and other applications where floor slabs are subject to high loads and wheeled traffic. Its use can minimise slab depth, saving time and materials, and prevent uneven

Ancon ADD 75/10
Ancon individual plate dowels are a cost-effective means of transferring shear loads and accommodating movement in load bearing ground floors. The Ancon ADD 75/10 is suitable for the majority of applications.

Ancon AHM 100/10
Where a greater capacity is required or wider than average joint widths are anticipated, the Ancon AHM 100/10 system should be considered. The larger steel plate of this system provides a greater surface area to reduce bearing stresses on the concrete. This dowel typically provides a 30% increase in capacity for joints of over 20mm in slabs greater than 250mm.
