CAVITY WALL TIE SELECTIONThe selection and spacing of wall ties dependon many factors. These include type ofbrick/block to be tied, cavity width, type andheight of building, location, and design life.There are several documents which need to be consulted.

BS 5628 : The Use of Masonry :Part 1 : 1992The Masonry Code allows wall ties to eitherDD140 or BS1243 to be used.Recommendations are given on embedment,length of tie, density and positioning.

DD140 : Part 2 : 1987 : Recommendationsfor the Design of Wall TiesThis document gives recommendations for thedesign of wall ties for use in masonry andtimber construction in the UK. Ties areclassified by type. The relevant classification isdetermined by strength, function and use.Types 1 to 4 cover masonry-to-masonry ties,Types 5 and 6 cover masonry-to-timberconstruction.

The majority of Ancon and Staifix cavity wallties are designed to the requirements ofDD140: Part 2. These ties provide cost savingsover the BS1243 equivalents.

Density & Positioning of Ties For walls in which both leaves are 90mm orthicker, ties should be used at not less than2.5 per square metre (900mm horizontal x450mm vertical centres). This spacing may bevaried when required by the BuildingRegulations. Ties should be evenly distributedover the wall area, except around openings,and should preferably be staggered.

In cases where insulation board is incorporatedwithin the cavity and restrained by ties withinsulation retaining clips, it may be necessaryto reduce the horizontal spacing of the ties to600mm. At vertical edges of an opening,unreturned or unbonded edges, and verticalexpansion joints, additional ties should beused at a rate of one per 300mm height,located not more than 225mm from the edge.A typical layout is shown below. Various detailsincorporating debonding ties at verticalmovement joints are shown on page 12.

Length of Tie & EmbedmentWall ties should be of the correct length toensure they are properly embedded in themasonry. The tie should have a minimumembedment of 50mm in each leaf but alsotake site tolerances into account for bothcavity width and centring of the tie. For thisreason we suggest tie lengths which achievean embedment of between 62.5mm and75mm.

Recommended lengths to suit various cavitywidths are shown for masonry-to-masonry wall ties.

BUILDING REGULATIONS PART E:RESISTANCE TO THE PASSAGE OFSOUND

The 2003 edition of Part E of the BuildingRegulations includes new requirements for wallties. There are two classifications: Type A andType B. Two new logos are shown throughoutthis brochure to indicate the Ancon and Staifixwall ties that meet these requirements.

Type A for separating or external wallsThese ties must either be butterfly ties toBS1243, and only used in 50mm to 75mmcavities, or ties with a measured dynamicstiffness of <4.8MN/m3 taking both cavitywidth and tie density into account.

This logo indicates theties with a measureddynamic stiffness of<4.8MN/m3 for the

specified minimum cavity and at a density of2.5ties/m2 (900mm x 450mm centres).

Type B for external walls where a type Atie is not suitableThese ties must either be double triangle tiesto BS1243, and only used in 50mm to 75mmcavities, or ties with a measured dynamicstiffness of <113MN/m3 taking both cavitywidth and tie density into account.

This logo indicates theties with a measureddynamic stiffness of<113MN/m3 for the

specified minimum cavity and at a density of2.5ties/m2 (900mm x 450mm centres).

Independent tests have proven that thefollowing groups of Ancon and Staifix wall tieseasily meet the new Part E requirements foruse in external cavity masonry walls:

• Wire Ties

• Helical Ties

• Timber Frame Ties

• Flat Ties (including Two-Part Ties, Frame Cramps and Channel Ties)

To ensure cavity wall ties are effective at tyingthe leaves together they should be installed asthe inner leaf is constructed and not simplypushed into a joint. To encourage good sitepractice, all cavity wall ties which could bepushed into the mortar joints of a pre-constructed wall are manufactured withspread safety ends. If installed in this way thewidest part of the safety end leaves a mark inthe mortar each side of the tie.

Ancon frame ties and channel ties aremanufactured with a non-spread safety endallowing the use of a debonding sleeve. Thistype of safety end reduces the variety of tiesrequired on site.

INSTALLATION GUIDANCEWall ties are important to the stability ofmasonry and failure to install them correctlymay lead to damp penetration, cracking oreven the collapse of walls.

Wall ties should be pressed down in freshmortar. They should be surrounded by mortarand not simply positioned directly ontomasonry with mortar placed around them.

Ideally, ties should be installed with a slight fallto the outer leaf, not towards the inner leaf asthis could provide a path for moisture to crossthe cavity.

The drip part of the tie should point downwardand be positioned near the centre of the opencavity. Ties with multiple drips, like the StaifixRT2, can often be positioned centrally as partof the drip will normally be near the centre ofthe open section of a partial fill cavity.

Installed ties should be clear of mortardroppings to allow the drip to function andprevent water from crossing to the inner leaf of masonry.

The practice of bending up installed wire tiesshould be discouraged. This can adverselyaffect the performance of the tie and weakenthe embedment in the inner leaf. Rigid ties likethe Ancon SD1 and ST1 should never be benton site.

TIES FOR THIN-JOINT BLOCKWORKThin-joint construction prevents the use oftraditional cavity wall ties requiring embedmentin 10mm joints and coursing between the innerand outer leaves. The joints in the inner leaf ofblockwork are reduced to 3mm or less by theuse of special thin-joint mortar designed tospeed the rate of construction.

Staifix-Thor Helical TJ2 Wall TieThe TJ2 wall tie hammers directly into aeratedconcrete blocks, through insulation material,and is built into the bed joints of the outer leafof brickwork. It is ideal for thin-joint blockworkand other applications where the joints in theinner and outer leaves are not aligned. This tiemeets the requirements of the NHBC, BS EN845-1 and DD140 : Part 2 as a type 2, 3 or 4wall tie depending on the block used. Tools areavailable to simplify installation.

TIES FOR STEEL STUDWORK

Ancon 25/14 Restraint SystemThe Ancon 25/14 channel system is designedto tie brickwork to steel studding. Self-drill self-tap screws fix through the channel and theinsulation material, into the steel. Once thechannel is installed, Ancon SD25 wall ties canbe positioned at any point along its length andare built into the bed joints of the outer leaf ofbrickwork.

The spacing of ties is based on the height ofbuilding and its geographical location. The tablebelow should be used in conjunction with thewind speed map on page 4.

Ancon recommends that wall ties achieve aminimum embedment of 62.5mm in the outerleaf of brickwork. Applications with a 50mmopen cavity require 100mm long ties.

25/14 channel features pre-punched holes atclose centres to ensure a fixing position isalways located near the end, even when it iscut on site. It should be fixed to steel studworkat 450mm vertical centres.

Screws are available to accommodate aninsulation thickness of up to 60mm. Anconrecommends the use of stainless steel fixingscrews. Alternative screws are available.

The channel has a 16mm opening to easilyaccommodate a drive socket and washer forthe fixing screws.

This system has been independently tested atCERAM Building Technology and meets thetechnical requirements of the NHBC.

ANCON FRAME CRAMPSFrame cramps can be fixed to concrete,steelwork or masonry and have a single 7mmdiameter hole or an 8mm x 30mm vertical slot.Ancon M6 Single Expansion bolts arerecommended for fixing to concrete, setscrews or self-drilling screws for steelwork,and suitable plugs and screws for fixing tomasonry. Large washers must be used with allSDVs and similar ties with a slot. Other fixingsmay also be suitable.

Poor substrates will limit the capacity of framecramps and site testing may be advisable insome cases. The performance will also bedetermined by the position of the fixing. SDVties fixed to steelwork or concrete at thelowest point of the slot will have a safe workingload of approximately 1kN. The capacity willreduce as the fixing is moved further awayfrom the bend and greater movement must beexpected than with other types of wall tie.

Ancon isolation sleeves and pads are suppliedblank for use with self-drilling screws to isolatestainless steel frame cramps from mild steel.

Ancon ISO-TW Isolation WasherThe ISO-TW Isolation Washer has beendesigned for use with Ancon frame crampsreferenced _ _ V when fixing to steel frames. In addition to separating the dissimilarmaterials it allows cramps to be fixed to steelcolumns in advance of the masonry. Finaladjustments to suit mortar joint levels can bemade within the 30mm range of the slotwithout affecting the integrity of the fixing. The practice of pre-fixing frame cramps canspeed the construction process.

Ancon HiT - Hammer-in TieThe Ancon HiT fixes masonry cladding toconcrete. It can reduce the variety of tielengths required on site and speed the rate ofconstruction. The HiT is available in a standardlength of 310mm that is bent on site with aspecial installation tool to suit all cavities up to150mm. Unlike conventional frame cramps itdoes not require a mechanical fixing, but ishammered into a plug. The Ancon HiT meetsthe requirements of DD140 as a Type 2 tie. Aneoprene 'O' ring must be installed on the tieto prevent moisture crossing the cavity.

Note: Frame cramps should have a minimum embedment of 50mm in the outer leaf. Taking site tolerances into account,Ancon suggests tie lengths which achieve a greater embedment.

ANCON BRICLOKTraditional methods of fixing masonry tosteelwork, using frame cramps which are boltedto the column, can be difficult, time consumingand expensive. This slows down the laying ofbricks, wasting valuable production time on site.

Ancon BriclokLengths 150, 200mm

Ancon Briclok offers simplicity by eliminatingthe need for specialist tools and complexoperations. The tie is positioned with the mostsuitable notch around the column flange withno less than 10mm engagement. The tie mustnot be forced onto the flange.

Bi-metallic contact in damp conditions maycause the column to suffer some slight surfacecorrosion. This will not affect the structuralperformance of either the Briclok or thecolumn. Mild steel columns will usually beprotected. However, bitumen paint, applied bybrush at the contact area will help alleviatecorrosion of the column. Briclok Ties restrainthe inner leaf and sustain loads which exceedthe requirements for a Type 2 tie to DD140.

ANCON COLUMN TIESAncon Column Ties, which clamp to theflanges of structural steel columns, can beused across the cavity to the brickwork orback into the blockwork.

These are available in different lengths and willaccommodate flanges from 6mm to 25mm.

ANCON SLIP-BRICK TIESAncon Slip-Brick Ties are bolted directly toblockwork or concrete to give both supportand restraint to thin slip brick facings. Inaddition to the standard three brick version,slip brick ties can be manufactured in othermultiples on request.

RESTRAINTS FOR STONE CLADDINGReference should be made to BS 8298 : 1994“Design and installation of natural stonecladding”, when selecting ties for restrainingstone cladding. Restraints should be designedto resist wind loads and any imposed loadsfrom, for example, window cleaning equipment.

Each stone will normally be restrained in fourplaces, two at the top and two at the bottom.These are usually situated in the horizontaljoints. The restraints should be located in pre-formed mortices or holes positioned in thecentre of the thickness of the stone panel, andlocated at 1/4 points for half bonded stonesand 1/5 points for stack bonded stones.Restraints should be kept at least 75mm fromany corner with the peripheral distances betweenany two restraints not exceeding 1200mm.

The embedment of restraint dowels and lips into the stone should be at least 20mm. To achieve this lipped ties, (LPBs) have a25mm downstand and dowelled ties (DPBsand YPBs) have 60mm long dowels.

Ancon FHR - Head RestraintThe Ancon FHR Head Restraint is used forrestraining the top of internal walls or theinternal leaf of a cavity wall. The two anglesclamp the top of the wall and have 10mmdiameter holes to suit M8 bolts. They aresupplied with two holes in the longer angle toallow the restraint to fit 100mm and 140mmblockwork. Each restraint can resist a serviceload of 1kN.

ANCON HEAD RESTRAINTS Ancon Head Restraints provide the necessaryrestraint to the top of masonry walls. Theyallow for vertical movement to accommodateshrinkage or thermal movement of the wall orstructural frame, while restraining wind loads.

Ancon IHR - Internal Head RestraintThe Ancon IHR is used for restraining the topof internal walls or the top of the inner leaf of acavity wall. The opening at the front of thechannel stem is sealed to prevent mortaringress and to ensure that vertical movementcan take place between the blockwork and thestructure. The base of the stem must be builtwithin a bed joint with the centre of the stemno closer than 50mm from the edge of theblock. The vertical joint should be filled withmortar each side of the stem. The maximumjoint between the top of the blockwork and theunderside of the frame should not be greaterthan 25mm.

The sliding tie can be provided with either ahole or slot to suit M8 bolts, or with a notchend to fix directly into a 38/17 or 30/20 cast-inchannel. The standard Ancon IHR will suit a215mm high block and can resist a load of1.5kN. Other sizes between 150 - 250mm are available.

Installation of Remedial Wall TiesMechanical ties are easily installed by meansof two Setting Tools. The tie is fitted to thesetting tool for the inner leaf and inserted intoa pre-drilled hole in the wall. The required drilldepth for each tie is shown in the table below.The inner shell is expanded by turning thehandle until the correct torque is reached. The tool for the outer leaf, with a hexagonal-shaped end, is then fitted and adjusted toexpand the outer shell. The process is quickand simple and ensures that each tie iscorrectly installed.

REMEDIAL WALL TIES

Corrosion of Cavity Wall TiesWall ties are an essential element in thestability of masonry panels. Prior to 1978, wallties were usually manufactured from galvanisedmild steel. These ties were expected to last thelifetime of the building, but for many years ithas been recognised that some of these wallties have corroded after only 15 or 20 years.

When these ties corrode, they can expand to seven times their original thickness. This causes the brickwork to crack at themortar joints and can result in major damageand sometimes the collapse of walls.

It is crucial that the problem is identified asquickly as possible and the correct remedialaction undertaken.

Ancon 63 RangeThis is the original remedial wall tie which hasbeen used in various forms since 1972. The Ancon 63 range has been continuallyimproved to keep pace with changingrequirements. These ties are easy to install anda secure fixing is achieved with a minimumamount of disturbance.

Highly corrosion-resistant materials are usedthroughout the 63 range. The grade 304stainless steel body of the MM 63 hasexpansion shells at both ends for installationinto a 10.5mm diameter hole. A neoprene ringprevents moisture travelling past the centre ofthe tie.

Test ResultsThe '63 ties have been tested independently ina variety of materials using the standard '63tie, a summary of results is given in the table.The failure loads noted in the table areobtained from couplet tests in accordance withDD140 : Part 1 and provide indicative values oftie performance. The couplet test producesresults of a conservative nature compared toactual wall tests. Due to the variability ofmaterials, it is often prudent to undertake apull-out test on site, to verify the selection ofan appropriate tie.
