1.0Density and Positioning of Ties

This diagram shows the typical positioning anddensity of ties for standard situations. BS5628: Part 1 recommends that where both leaves of a wall are at least 90mm, tie density should be no less than 2.5 ties per square metre (900mmhorizontal x 450mm vertical centres). Where thecavity width exceeds 75mm, building regulationsrequire the horizontal spacing to be 750mmmaximum, although all can vary if building regulationsrequire. Ideally the ties should be staggered andevenly distributed over the wall area, except whereopenings do not allow this to happen. Extra ties atone per 300mm height should be used at thevertical edges of an opening, unreturned or unbondededge and vertical expansion joints. In these cases,the ties should be less than 225mm from the edge.If insulation board is used in the cavity and restrainedby ties using insulation retaining clips, the horizontaltie spacing may have to reduce to 600mm.

RELEVANT BRITISH STANDARDS: BS1243: 1978 Specification of Metal Ties For Cavity Wall Construction. This now largely out-dated standard has been superseded by DD140 in most respects. It specifiesthe three traditional types of wall tie (i.e. vertical twist, double triangle and butterfly) and defines the shape, material and manufacturing tolerances for each tie.

BS5628: Part 1: 1992 Structural use of Unreinforced Masonry. This is the standard masonry construction code, providing recommendations on density, positioning, embedment and lengths of ties.

Building Regulations 2000 Approved. Document E: Resistance to the Passage of sound. Provides procedures for sound insulation testing and the measurement of dynamic stiffness of wall ties.

DD140: Part 2: 1987 Recommendation for the Design of Wall Ties. Provides recommendations for the design of wall ties for use in masonry and timber construction in the UK. Allows for the designof new wall ties which are then performance tested to determine classification in accordance with end use. Classification type 1 to type 4 cover masonry construction. Ties must meet minimum characteristic tensile and compressive force requirements noted in DD140

Building Regulations Approved Documents: 1995 BRE Digest 329: Installing wall ties in existing construction recommendations on density, positioning, embedment and lengths of ties.

9WINCRO MOVEMENT TIES > VERTICAL MOVEMENT JOINTS

WINCRO MOVEMENT TIESVERTICAL MOVEMENT JOINTS

At vertical movement joints the use of de-bonding sleeves on plain ended wall ties play a dual role, masonryis allowed to expand or contract while at the same time the tie restrains the masonry against lateral wind loads.The Wincro WDS de-bonding sleeves, are used at joints where there can be horizontal movement. Wincrorecommends that de-bonding sleeves are installed with a 10mm gap at the end to allow for expansion.

All structures are subject to movement after construction because of influences ranging from temperature to ground movement and differential settlement. It is essential, therefore, that provision for movement is made at the design stage, and that it is made bearing in mind the overall stability of the structure.

WINCRO FRAME CRAMPSCRAMP FIXING APPLICATIONS FOR FIXING TO CONCRETE AND STEELWORK

Wincro’s standard frame cramp has two outer 6mm diameter holes and one central 7mm diameter hole.Different methods are recommended for use in fixing to steelwork and fixing to concrete.

When frame cramps are fixed to steelwork, the following is recommended:Use a WBSD zinc-plated carbon steel self-drilling/self-tapping screw complete with a neoprene isolationwasher and a neoprene isolating patch between the frame cramp and the steel section. This eliminates the possibility of bi-metallic corrosion.

When frame cramps are fixed to concrete the following is recommended:Use a WBPS Plug and screw using either the 7mm diameter central hole or the two 6mm diameter holesor use WBEB M6 expansion bolt through the 7mm diameter central hole.

Wincro recommend large plate washers should be used as this increases the tensile load capacity of frame cramps.

Please contact our Technical Design team for further guidance.

UNIVERSAL COLUMN TIE

Wincro’s universal column tie is a simple and time-saving answer to tying masonry to steelwork. It is better than the traditional bolted or shot-fired ties and cramps. Benefits include:

4 different fitting optionsEase of installation with no fitting tools or equipment requiredAllows for variation in coursingEasy to handleExcellent pull-out strengthExceeds the requirements of DD140 for a Type 2 tieManufactured from high quality grade 1.4301 (304) stainless steel

Variation in notch sizes means the Wincro universal column tie can be slotted easily around the flange of a column and so provide an effective restraint between the inner and outer leaves of masonry cavity walls.

Note: Where the tie is used with untreated mild steel structural steelwork, it is advisable to paint the flange with a bitumen coat where the two materials come into contact.

12 WINCRO FASTRACK TIE SYSTEM


WINCRO FASTRACK TIE SYSTEM

The Fastrack Systems are designed to overcome common site problems in differential coursing when using different masonry types/sizes or when one leaf of the cavity is built prior to the other. This method ofconstruction also eliminates the extra hazard of ties projecting from the inner leaf. A short lengths of WC28Channel with one restraint tie welded to the rear of the channel is used in conjunction with a WT##C28Channel tie, available in various outer fixing ends and lengths (see page 7-8 for selection).

Wincro’s Fastrack Channel and Ties are available in various lengths and exceed the requirements for a Type 2 tie to DD140.

15WINCRO HEAD RESTRAINTS

WINCRO HEAD RESTRAINTSThe Wincro WT75HR blockwork head restraint is designed to span a standard 215mm deep block, but canbe adjusted for block depths between 190mm and 275mm. It is made from high quality grade 1.4301 (304)stainless steel and provides both a fast and economic alternative to traditional restraint methods such asbolted angles and can eliminate costly fire protection.

It is designed to be built into the perpend joint at the head of non loadbearing, internal blockwork walls,incorporating soffit movement and providing resistance to lateral loads up to 1.5kN.

Normally used at 900mm centres, it can be used with the WBEB M8 expanding bolt or with a Wincro channeltie fixed into a Wincro WC28 or WC38 cast-in channel (see Channel and Bolt Fixings section). The WincroWT75HR can be also fixed to steel framework with a setscrew and using a neoprene patch to separate thedissimilar metals.

The Wincro WT75BHR is a Universal Head Restraint and is designed to withstand a 1kN safe working load.Positioning/spacings of the WT75BHR are normally at 600-900mm centres although this detail is normallyrecommended by the Structural Engineer.

WINCRO SLIDING BRICK ANCHORSWT75 SLIDING BRICK ANCHORS

Sliding brick anchors are lateral restraint fixings which provide a mechanical tie between masonry claddingpanels and the steel or concrete frame where a movement joint is used. The anchor allows movementbetween the masonry and frame structure as well as improving resistance to wind loadings. The anchor fixesto the face or soffit of a structure and has one way or two way ties into the panel courses.

Wincro’s standard range of sliding brick anchors have a 350mm stem and will resist wind loads of up to1.5kN. If required, longer stems can be provided, and while a wide range of head fixings is available, specialholes can be made to produce a bespoke product where required.

The stems fit within the cavity and take ties that can slide up and down to account for vertical movement.

All components are made from high quality type 1.4301 (304) stainless steel.

18 WINCRO STONE FIXING TIES & CRAMPS


WINCRO STONE FIXING TIES & CRAMPSWincro has developed a range of stone fixing ties and cramps to meet the every increasing demand for stoneclad features. The most appropriate stone tie will vary according to the type of cladding or features being used.

The selection of both ties and restraints should take into account both natural wind loads and any artificiallycreated loads, such as from window cleaning equipment.

Our Technical Design Team are available to discuss how best to meet your requirements, either from ourstandard range or by the production of bespoke solutions for your particular application.

BS8298:1994 ‘Design and installation of natural stone cladding’ should be consulted when making your choice of ties and restraints.

WINCRO MASONRY REINFORCEMENTWincro masonry reinforcement has a number of applications such as providing additional strength to masonrycladding panels, strengthening both inner and outer leaves of cavity walls and offering an alternative cavityrestraint fixing. The masonry reinforcement system permits larger cladding panel spans to be incorporatedand also gives the option of using narrower inner blocks than those used with un-reinforced panels.

Wincro has developed a range of welded Masonry Reinforcement to overcome structural problems as well as crack control.

The Wincro Reinforcement range is available in high quality 1.4301(304) stainless steel and in a full range of widths to suit any brick or block thicknesses.

BS5628 Part 2 recommends that stainless steel material should be used in external walls, including the innerleaf of the cavity. Wincro can supply a suitable alternative to any Specified Reinforcement. If required designcalculations for approval can be submitted.
