SHEAR LOAD CONNECTORS

SHEAR LOAD CONNECTORSAncon shear connectors offer significant advantages overconventional single dowels. The two-part construction meansthat the sleeve component can be simply nailed to theformwork, drilling or either formwork or concrete is notrequired. The dowel unit can then be inserted into the sleeve.The engineered nature of the two components ensuresalignment, vital where movement is required.

DSDThe DSD is the original two-part, double dowel, shear load connector. The dowel component can move longitudinally within the sleeve to accommodate movement.

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

ESDThis single dowel shear connector is available in three sizes with each size available in two lengths. ESD shear connectors are used where the slab or wall is too thin for DSD, and where loads are small.

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

DOWEL BAR CRADLESDowel Bar Cradles are used to support dowel bars in contraction and expansion joints. When ordering please confirm type, height (which is from base of cage to bottom of dowel bar) and quantity required. Manufactured to customer requirements. Sold per metre.

STRIP JOINT CORNERSThis provides the benefits of an armoured joint arris for tied or free contraction joints and is designed to be used with traditional timber forms. It is manufactured from 10mm thick x 50mm deep square edged bright mild metal strip which has a very flat top surface (unlike hot rolled strip or angle, which produces a radiused top edge). 10mm diameter x 100mm long shear studs are stud-welded to the strips to ensure maximum keying into the slab. Angle metal strips are supplied for tied joints with shear studs welded on both sides of the strip to tie into the concrete on either side of the joint. Double Metal Strips are supplied for free contraction joints which have shear studs welded on one side of each strip. The two strips are hollow dowelled together and an 8mm nylon bolt passes through the dowel which shears when the joint opens.

TIEFILLFor the filling of tie-holes formed by formwork bolts in new construction, particularly where a rapid setting, durable, waterproof mortar is required. Tiefill is a single component, polymer modified, fibre reinforced, Portland cement based repair compound, which exhibits unique hydraulic properties to produce a rapid curing mortar with enhanced polymer properties. It only requires the addition of clean water to give a rapid setting, yet durable high strength mortar and is ideally suited for the filling of voids particularly in new construction which need to be rapidly put into service, such as tie-holes, grout holes and voids around fixings. For the treatment of tie-holes formed by through-ties, any remaining plastic tube should be cut back and removed to approximately 40-50mm from the concrete face. To eliminate the possibility of water tracking around the plastic tube, it should be plugged with cork or a proprietary stopper. Tiefill is a WRAS approved product confirming suitability for use in contact with potable water and it is CE Marked in compliance with EN 1504-3 Class R4.

METAL FORMWORK

PERMANENT FORMWORKAn expanded metal sheet product, specifically developed for use as permanent formwork to concrete. The profile of the open mesh, in combination with tangs, allow the development of dense concrete nodules and indents on the face, forming an enhanced mechanical key for the second phase pour. In the case of visible elements, the resulting surface is suitable to receive a rendered or tiled finish.

Primarily used in construction joint applications but it is also used to form wall, beam & column surfaces and slabs soffits, where the formed surface will not be seen.

POLYTHENE SHEETING

POLYTHENEOn the roll polythene is the ideal general protection product. We can supply centre folded, for example a four metre wide sheet of plastic would be folded onto a one metre roll for ease of storage and transportation. This product eliminates the multi-fold creases that act as crack inducers.

Rolls can also be supplied in larger sizes where mechanical handling facilities are available on site. The use of a larger roll reduces laying time and the quantities of tape used for joints.

REINFORCEMENT CONTINUITY SYSTEMSEAZISTRIP CONTINUITY SYSTEMEazistrip Reinforcement Continuity Systems are designed to maintain continuity of reinforcement at construction joints in concrete. Formwork design is simplified and there is no need to drill shuttering. Each unit consists of a galvanised steel casing which is dimpled to provide an effective concrete bond. Pre-bent bars are housed within the box and are secured by a protective cover. When the cover is removed the bars can be straightened ready for lapping onto the main reinforcement. Bars must be straightened only once, using an Eazistrip re-bending tool.

When the potential for water ingress through the construction joint is a major concern, Eazistrip can be supplied with a Pentaflex hydrostatic seal which provides protection against moisture permeation along the joint face.

Eazistrip Reinforcement Continuity systems are CARES approved. The grade of reinforcing bar used is Grade 500B, minimum yield 500N/mm2, minimum uniform elongation Agt 5%. The bars are bent in accordance with BS8666.Applications• Walls• Floor slabs• Stairwells• Slip forms• Gutters

The positional couplers are suitable for a bent or straight reinforcement bar, of which neither can be rotated, and where the space for the connected bar is limited. Please refer to data sheet for correct installation instructions.

MBT COUPLERSThe MBT range of couplers provides a cost-effective method of joining reinforcing bars, particularly when the fixed bar is already in place. They are easy to install and achieve failure loads higher than 115% of the characteristic yield strength of grade 500 reinforcing bar. Neither bar end preparation to form threads, nor bar rotation are required. MBT couplers can also be used to join imperial, plain round or deformed reinforcing bars.

When the pre-determined tightening torque for the bolts is reached, the heads shear off leaving the top of the installed bolt slightly proud of the coupler. This provides an instant visual check of correct installation.

MBT ET SERIESET series couplers are used to connect reinforcing bars of the same diameter. They can be used when neither bar can be rotated and are available in sizes 10mm to 40mm.

MBT HEADED ANCHORSMBT Headed Anchors are designed to provide dead end embedment for bars in concrete. This helps to reduce congestion and simplify the placement of rebars by removing the need for hooked ends. The anchor comprises half an MBT coupler with a plate welded to one end which carries the full tension load of the bar when it is bearing against the concrete. The MBT Headed Anchor also has the added advantage of requiring no special bar end preparation.

INSULATED AND REINFORCED BALCONY CONNECTORS

ANCON ISOLANThe Ancon Isolan system joins external concrete balconies to internal concrete floor slabs. It provides continuity to both the reinforcement and the thermal insulation of the wall protecting the building against the effects of cold bridging. Standard systems, comprising rigid CFC-free polystyrene insulation and stainless steel shear reinforcement, are available in five heights to suit different slab depths. Conventional reinforcing bars (supplied by others) provide the tension and compression reinforcement.

System BenefitsAncon Isolan connectors use conventional reinforcing bars (grade 500B to BS4449: 2005) to provide the tension and compression reinforcement. When compared to systems where this reinforcement is an integral component, the Ancon Isolan solution can provide substantial cost savings and simplify specification, scheduling, transportation, handling and installation.

MV SystemThe Ancon Isolan MV system is used for the transfer of moment and shear forces in cantilevered balconies.

V SystemThe Ancon Isolan V system is used for the transfer of shear forces in simply supported balconies.

PUNCHING SHEAR REINFORCEMENTANCON SHEARFIXAncon Shearfix is used within a slab to provide additional reinforcement around a column head or base. The system comprises double-headed studs welded to flat rails. Studs are manufactured from high strength steel bar in six diameters and in lengths to suit the depth of slab. Shearfix rails are manufactured from strips of steel, 16mm wide. The quantity of studs and rails, their dimensions and spacings, and the layout pattern around the column is determined by calculation.Ancon Shearfix

ACCESSORIESFROST BLANKETSApplication: Laying concrete at temperatures below 5ºC generally requires special precautions (such as special concrete additives, heating devices, hot vapour equipment etc.). An easy and inexpensive solution is the use of Frost Blankets. The thermal insulation effect of the Frost Blanket significantly reduces the loss of natural concrete hydration heat and thereby keeps the concrete warm long enough for a safe curing.

BenefitsConcrete laying in summer and winter season. The combination of their excellent thermal insulation performance, their negligible water absorption and their flexibility make Frost Blankets ideal for improved concrete curing.• Negligible water absorption.• Excellent thermal insulation.• Excellent chemical resistance.• Fast laying from the roll.

• Lightweight, easy to handle and cut.• Good mechanical resistance.• Flexible at very low temperatures.

Frost blankets from SIG CA can be directly rolled onto the wet concrete. Wind conditions might necessitate the mats being held in place by suitable loading at the contractor’s discretion. Beware not to walk on the mats during installation and before hardening of the concrete.

Available in roll size 6m x 1.2m x 48m (+/-5% tolerance on width and length).
