3INTRODUCTION TO CHANNELS

Wincro channels provide positive anchorage for fixing components and allow generous tolerances for setting-out. The use of Wincro channels often eliminates the need for the costly and time consumingprocedure of site drilling of either concrete or steelwork. Wincro supply a range of stainless steel channelsections either for casting into concrete or surface fixing to the face of a structure.

The Wincro Channels range include: Light duty self anchoring channels for restraining masonry through to Heavy duty channels complete with welded wavy tail anchors.

All cast-in channels will not produce expansive forces and enable closer edge fixing than expansion anchors.

Our cast-in range are supplied with nail holes for securing to shuttering and are filled with expandedpolystyrene to prevent the ingress of concrete during casting.

INTRODUCTION TO CHANNELS

SURFACE FIXED

Plain back channels can be surface-fixed to concrete and to steelwork, and in certain situations to masonry(normally as a wall starter for use with ties).

Wincro’s WC27 Channel system has been developed to fix back to steel studwork using the WincroWBSDD65ZP to prevent any crushing of the insulation batts (for further details on this particular system please see our Ties and Restraints Section).

FIXING GUIDE FOR CAST-IN CHANNELS

MINIMUM EDGE DISTANCES

Dimensions from the centre of the channel to the edges of the concrete should not be less than the minimum edge distance stated, applicable to the range of channels in pages 5-7.

Fixing Timber Shuttering

Wincro Cast-in Channels are generally supplied in 3m lengthswith welded wavy tail anchors, nail holes and polystyrene infill.

To prevent the channel from pulling away from the shutteringand to avoid the ingress of concrete, Wincro recommendthat all nail holes be used.

To assist with the removal of the shuttering and to ensure thestability of the channel, Wincro recommend that all nails havea plain shaft and be installed at right angles to the channel.

Installation for Steel Shuttering

Wincro standard T Head Bolts can be used when fixing to steel shuttering through pre-drilled holes.

Fabrication

Wincro recommend that if channels with wavy tail anchors are required to be cut on site, there must be a completeanchor retained inside 50mm from the end of the channel.

A welded corner fabrication must be used on all externalcorners where horizontal cast-in channel is used with theWincro Masonry Support Systems.

Taking away Shuttering

Care should be taken to ensure that when the concrete is poured,that it is completely compressed around the rear of the channelparticularly adjoining the wavy tail anchors. When the concretehas cured, the shuttering is removed, the nails can either becut or turned away from obstructing any tie or T Head bolt.

9WBEB EXPANSION BOLT TECHNICAL GUIDE

WBEB EXPANSION BOLT TECHNICAL GUIDE

DIRECTION OF LOADING: The direction of the applied load must be considered to determine the most appropriate anchor.The tension and shear components must be less than the recommended safe working loads in the direction concerned.TENSILE LOAD: Tensile loads are applied along the axis of the fixing. Common examples include suspended ceilingapplications and the suspension of mechanical services, pipework and ductwork etc. Tensile load performance dependson the correct installation of the anchor.SHEAR LOAD: Shear loads act at right angles to the axis of a fixing and directly against the face of the structural material.Shear performance is governed mainly by the shear strength of the bolt material and in close edge distances compressivestrength of the supporting substrate.OBLIQUE/COMBINED LOADS: Oblique loads are a combination of tension and shear components. If the angle of applied oblique load is within 10º of pure tension or pure shear, the safe working load for that direction maybe assumed. Otherwise, the applied oblique load should be resolved into its shear and tensile components which must be less than the appropriate safe working loads.OFFSET LOADS: Offset loads act at right angles to the fixing axis but are offset from the surface. This is effectively a bending Moment and the load carrying capacity of the anchor in this condition is reduced from its capacity in shear. Correct guidance is available from our Technical Design Team.

RECOMMENDED TIGHTENING TORQUE: In torque controlled expansion anchors a clamping force is exerted through the fixture to the base material. The clamping force is proportional to the tightening torque. Tightening the anchor hexbolt or hexnut enables the expander to key into the surrounding substrate providing a secure fixing.

Tightening to Wincro’s recommended torques ensures the clamping force is greater than the published safe working loads.The torques should not be exceeded as this may overstress the bolt material.

Adjustable torque wrenches of the ‘break back’ type are recommended for setting fixings.

EXPANDED FIXINGS: Torque controlled expansion anchors transmit expansion forces by locally compressing thesubstrate. The expansion forces are exerted at the point of expansion, not over the whole length of fixing.

On applying the load to the anchor, additional forces are exerted as shown by the projected area, i.e. concrete cone.It is this projected areas which relates to the performance of the anchor. Therefore, as embedment depth is increased thelarger cone and the performance of the anchor is increased until the mode of failure changes to steel failure.

Any reduction in the projected area, for example when anchors are placed too close together or too near the edge ofconcrete will result in reduced performance and should be avoided if possible. Where unavoidable, the appropriate reductionfactors shown for reduced spacing or edge distance (tables 2.0 & 3.0) should be applied for the safe working load shownin table 4.0.

To establish safe working loads the following criteriaare to be met:

SAFETY MARGINSafe working load = x –KS

Where: x = The main ultimate load at failure

K = statistical confidence factor relating to sample size testedS = Standard deviation of test results found by statistical analysis

= Factor safety of 3 for torque controlledexpansion anchors

For Bonded Anchors Wincro suggest a safetymargin of greater than 4 to take account of variations to site conditions and operatortechnique.

FIXTURES WILL NOT MOVESafe Working Load < mean load at 0.1mm axialmovement of anchor due to tensile load

OR

Average Loading at 1.0mm movementperpendicular to the axis of the bolt due to shear loading, whichever is lower

ANCHOR MATERIAL WILL NOT BEOVERSTRESSED

Safe Working Load < the specified maximumworking tensile and shear stress for the particular bolt material in question, all inaccordance with the relevant material standard.

Note 1: The lowest value produced by these threemethods is used as the safe working load

Note 2: Other manufacturers and distributors may notapply the same stringent criteria to establishment of safe working loads as Wincro

Care should be exercised when comparingWincro Anchor performance to that of othercompanies.

CONCRETE STRENGTHThe safe static load (SSL) and failure loads shown in the product specific tables are for 30N/mm2

concrete unless otherwise stated. For other strengthconcrete (between 20 and 50N/mm2) the equivalenttensile load can be calculated using the followingempirical formula:

Tensile SSL = Tensile X Substrate strength

SSL in 30N/mm2 concrete 30

For example:

Tensile SSL in = Tensile SSL in

50N/mm2 concrete 30N/mm2 concrete x 50

30

= Tensile SSL in 30N/mm2 concrete x 1.29

Hence the tensile safe working load in 50N/mm2 concretewill be 29% greater than the figure shown in the table for 30N/mm2 concrete.

This calculation is only valid to tensile loads and cannot be applied to shear loads or failure loads. The formula is empirical, based on test results, in accordance withM.O.A.T. 49, and is intended for guidance only. A site test is recommended to validate these tests.

For further guidance contact our Technical Design Team.

SAFE WORKING LOADS: The recommended safe working loads published in this guide are for static application.Static applications include dead loads, sustained loads and variable loads where the peak load is lower than the safeworking load. Dynamic applications are generally not covered by this guide due to the range and complexity of theapplication. For guidance on dynamic applications contact our Technical Design Team.

DESIGN DATAConcrete

Loads shown are for 30N/mm2 (C20/25) concrete. For othergrades of concrete between 20 and 50N/mm2 where theanchor is in tension the load can be calculated using thefollowing empirical formula:

Combined Load (concrete only)

When selecting an anchor which will carry a combined load,ensure that the bolt size selected satisfies the following equation:

Edge and Spacing Distances

The loads shown are applicable to characteristic edge andspacing distances. For reduced edge and spacing distances,reduction factors must be calculated from the appropriate tables.

Reduction Factors – Edge and Spacing Distances

The characteristic edge and spacing distances quoted in thetable are the minimum allowable for the quoted safe loads toapply. Where the design dictates reduced edge and spacingdistances, the appropriate reduction factor/s from the tablesshown on page 12 must be applied to the safe working load.Choose the required bolt diameter across the top of the tableand read down the left hand column until actual edge orspacing distance is found. Read off the reduction factorwhere the two lines intersect (interpolate as required).Multiply this factor by the safe working load quoted in thetable. On the occasion that multiple close edge and/orspacing distances occur, the appropriate reduction factorsmust be applied.

Combined Load (concrete only)

When selecting an anchor which will carry a combined load, ensure that the bolt sizeselected satisfies the following equation:

WINCRO WBRG GLASS CAPSULE ANCHORS16


Wincro Glass Capsule is a high performance resin bonded anchor system that is used for safety-critical,structural applications. It does not expand and relies on the adhesion of the resin to the concrete, thereforeproviding a stress-free fixing. It can be used with studs or sockets in a wide range of good quality solid basedmaterials including stone, masonry, concrete and brickwork.

Wincro capsules contain epoxy acrylate resin and quartz granules plus a phial of hardener. The capsule andphial are broken and mixed in the hole by the action of driving the stud in with a drilling machine. The strength of the resin is unaffected by clean water but setting times will be longer.

DESIGN DATAConcrete

Loads shown are for 30N/mm2. For other grades of concreteplease contact our Technical Design Team.

Edge Distance and Spacing

The loads shown are applicable to normal edge and spacingdistances. For closer spacing and edge distances, reductionfactors must be calculated from the appropriate tables.
