10 Shear Load Connectors Beam Reinforcement The main consideration for beams is usually the design reinforcement to carry the shear load. This is provided in accordance with well established procedures set out in international codes, and will require shear links local to the Ancon DSD units. In addition to this reinforcement, particularly in thin beams, reinforcement must be added to prevent vertical splitting of the concrete. The reinforcement should be located as shown in the diagrams below.

The system eliminates the need to drill shuttering and can simplify formwork design, thereby accelerating the construction process. The Ancon Eazistrip is available in both standard units and special configurations. Reinforcing Bar Couplers The use of reinforcing bar couplers can provide significant advantages over lapped joints. Design and construction of the concrete can be simplified and the amount of reinforcement required can be reduced. Because the strength of a mechanical splice is independent of the concrete in which it is located, the joint can also remain unaffected by any loss of cover. The range includes threaded and mechanically bolted couplers. Punching Shear Reinforcement Used within a slab to provide additional reinforcement around columns, Ancon Shearfix is the ideal solution to the design and construction problems associated with punching shear. The system consists of double-headed studs welded to flat rails, positioned in a symmetrical pattern around the column head. The shear load from the slab is transferred through the studs into the column. Insulated Balcony Connectors Ancon Isolan connectors join external concrete balconies to internal floor slabs. Used to minimise cold bridging, they provide continuity to the thermal insulation. Standard systems, comprising rigid CFC-free polystyrene insulation and duplex stainless steel shear reinforcement, suit most depths of free cantilever and propped cantilever balconies. Conventional reinforcing bars are used to provide the tension and compression reinforcement. Channels and Bolts for Fixings to Concrete Cast-in channels are used for fixing masonry support systems to the edges of concrete floors and beams. Channels are available in different sizes ranging from simple self anchoring channels for restraints, to large capacity channels with integral anchors. A selection of channels can also be supplied plain-backed for surface fixing. Expansion bolts, resin anchors and set screws in stainless steel complete the range of fixings. 11
