Halfen - CRET Shear Dowel Connector

Introduction

Halfen CRET is a high load shear connector system to support floor slabs at movement joints. Each part of the shear connector, whether the sleeve or the dowel, is supplied complete with support box and vertical anchor rods allowing high shear loads to be transferred efficiently between concrete members.

Method of use

The support box and sleeve (either round or oval) are nailed to the formwork and cast into the first pour. The formwork is stripped, and the dowel pin and its support box are inserted ready for the second pour. Design gap and filler material specified by others.

Advantages

• More efficient shear load transfer across the movement joint than a simple dowel
• Vertical anchor rods and support box activate the maximum amount of the slab and reinforcement is simplified
• Fewer columns are required and more floor space gained
