General Guidelines

Design InformationThe integrity of the building or structure must be validated by a suitably qualifi ed Building Designer or Engineer (the “Designer”).The Designer is responsible for (i) determining that the appropriate connector and/or hanger has been selected and (ii) ensuring that the selected connector and/or hanger has been installed correctly.Location and spacing of straps to be specifi ed by the Designer.When selecting the appropriate connector and/or hanger, consideration must be given to the safe working load required, bearing support and connection details within the building or structure.Cullen reserve the right to (i) change the design specifi cations and applications of any connector/hanger, or (ii) withdraw any connector or hanger without giving prior notice. Cullen recommends the hanger height be at least 60% of the joist height for lateral stability.

••

Technical InformationThe technical information contained in this brochure is correct at the time of printing, (1st) January 2008. Cullen reserve the right to amend, change or update the technical information without giving prior notice. For current product updates and technical information, visit our website cullen-bp.com (the “Website”).

The contents of this brochure and the latest product updates posted on the Website supersede all previous Cullen publications including all brochures, installation guides, manuals and information sheets.

If you would like to receive technical bulletin updates and industry news, or would like to be informed of new Cullen products coming to the market, please register with us online or by e-mailing [email protected].

All safe working loads derived from tests witnessed & verifi ed by TimberSolve Ltd.

NB. Any modifi cation to any Cullen custom-made or manufactured connector and/or hanger product will void any warranty given by Cullen in relation to that particular connector and/or hanger product.

Custom Design ServicesIf required, Cullen can work with you to design connectors and hangers to meet your specifi c requirements. Our design and

technical department is available at 01592 777570 or e-mail at [email protected].

Proper product installation and construction practices must be followed at all times.Timber members and Engineered Wood Products may split when nailed; this may reduce their safe working load. To achieve the safe working loads published all specifi ed nails and fastenings must be used and installed as per the instructions set out in this brochure.Failure to follow proper nailing procedures and instructions will reduce the safe working load.Only bend Cullen connectors when directed to by the appropriate Cullen installation guide, and when necessary “only bend once”

General Guidelines

To achieve the safe working loads published in this technical manual, connections must be installed using the correct number and type of fasteners. Ensure all nails or screws are correctly installed prior to applying a load to the connector. Using alternative nails or screws from those specifi ed may alter the safe working load of the hanger connection.

Fastener Installation

3.75 x 30mm sherardised square twist nails are the standard fastener for Cullen and offer proven performance and ease of installation.

3.35 x 50mm stainless steel annular ring shank nails.

3.75 x 75mm round wire nails provide enhanced performance for certain connectors.

FastenMaster Connector Screws (FCS35) 35mm - For high-load applications, high performance FastenMaster Connector Screws are easily installed using a 18V cordless drill with a hex bit without the need for pre-drilling and provide excellent withdrawal and shear characteristics for a robust connection.

Steel Information

GALVANISED PROTECTION

Z275 galvanised coating is the minimum corrosion protection recommended in structural applications for use with untreated wood in many interior and exterior dry conditions.

Z600 galvanised coating gives greater corrosion protection with some treated wood applications and service environments.

Stainless steel fasteners should NOT be used with galvanised connections.

STAINLESS STEEL

Stainless steel provides the highest level of corrosion protection for certain exterior applications and timber treatments.

The treatment given to the timber may contain chemical elements that could cause a corrosive reaction to our connectors and specifi ed fasteners, in this case the wood treatment supplier should provide data sheets and recommendations of a compatible connector-coating product. If there is any doubt we recommend the use of stainless steel connectors and fasteners.

NB. Stainless steel fasteners must be used with stainless steel connections.NB2. Stainless steel fasteners do not have the same withdrawal capacity as regular nails. Safe working loads of stainless connectors available on request from Cullen.

Galvanised fasteners should NOT be used with stainless steel connections.

NB. Certain pneumatic nailing options can be used in conjunction with Cullen connectors, please contact Cullen Technical for further information on 01592 777570.

1200mm Minimum

A minimum number of connections should be made between the timber frame wall leafs of attached

dwellings, the purpose of which is to minimise the risk of sound transfer, therefore do not fi x the AWS at

horizontal centres closer than 1200mm.

Separating wall to intermediate fl oorWhere the separating wall meets an intermediate fl oor, the AWS is to be installed at or near ceiling level. Only one row of Acoustic Wall Straps to be installed per storey height.

Reducing horizontal impact noise transmission from sockets, switches and cupboards. Improving sound insulation against horizontal impact noise from plugs being inserted into sockets, wall mounted switches, doors and cupboard doors closing is a key

feature which many clients wish to have within their homes. The above graph illustrates the effective improvement by using the Cullen AWS versus standard separating wall straps and ties. Collectively over this important sound frequency range the AWS has

been found to improve impact noise insulation by 25 dB.

= =

Fix the panel closer across the panels to be joined using

4no. 3.35 x 50mm annular ring shank nails (nail holes in red).

Centrally position the panel closer between

panels. Drive the top plate onto the panel closer drawing the 2 panels together. The unique crumple zone will deform to

allow any gaps between the panels to be closed.

Once the top plate has been fully driven into position and the panels are tightly joined fi x the top plate by nailing

2no. 3.35 x 50mm annular ring shank nails into the permanent fi xing holes (nail holes in red).

Finally the panel closer must be nailed using 12no. 3.35 x 50mm annular ring shank nails to achieve the stated safe

working load (nail holes in red).

Meets the Requirements of EN 1995-1.1:2004 “The required vertical strength between 2 panels should be evaluated but should have a design strength of at least 2.5kN/m” For typical 2.5m panel height 2 panel closers will be required.

RD-DCR - Disproportionate Collapse Restraint

Disproportionate Collapse

The RD-Range was developed for joist to rim beam connections. The concept behind this design is that the fl oors are constructed as normal with the joists bearing onto the wall panel and the RD-DCR is then fi xed into position to restrain the joist. In the event of a disproportionate collapse situation arising (fi re, explosion etc.) the RD-DCR, although not normally used as a hanger, will act as a hanger to transfer the fl oor load to the rim beam which will have been designed to carry this load across the length of the panels.

The disproportionate collapse restraint system (RD range) is a multi-compliant solution that meets:

ADVANTAGESPermits increased standardisation of details for all storey heights.Improves low frequency sound insulation performance.Improves stiffness of the fl oor.

MATERIAL1.2mm galvanised mild steel - Z275

PERFORMANCE5.4kN Accidental safe working load

•••

The solid or engineered joist is supported on the timber frame below. The RD-DCR is connected to the rim beam and joist. This permits the timber separating fl oor to comply with the sound insulation requirements of Robust Details for Part E (RD Handbook E-FT-1 and E-FT-2) for all storey heights and comply with Part A disproportionate collapse requirements.

InstallationStage 1 Stage 2 Stage 3

Timber frame constructed as per manufacturer’s details. Rim beam sitting

onto head binder of panel.Floor joists sitting onto head binder of

panel allowing timber to timber bearing as per Robust Details E-FT-1 and E-FT-2.

Once joist is in place and abutting rim beam RD-DCR restraint is put in place

from the underside of joists.

Once RD-DCR restraint is in place then fully fi x to rim beam using 6no. 3.75 x

30mm square twist nails.

Nail 2no. 3.75 x 30mm square twist nails into joist.

Patent Pending

Part A: Compliant with Disproportionate Collapse requirements for 5 storeys or more

Part E: Compliant with Robust Details (E-FT-1 and E-FT-2) for timber frame structural junctions between timber separating fl oors and external walls

Part E - assisting towards compliance for Approved Document E performance requirements

Part L - Corner bracket system improves air tightness performance

JH/JHI - Masonry Joist Hangers

The JH/JHI timber - masonry hanger range is a single piece, non-welded connector. The higher side flanges help resist rotation while the wider masonry top flange spreads the loading over a greater surface area.

ADVANTAGESThe performance of the JH range is neither width nor depth dependent. It can therefore offer a single safe working load regardless of the situation.

General Notes1. Joist hanger must abut face of masonry wall to perform as quoted. Specifying return style hangers improves the chances of on-site compliance and produces a more robust detail.2. All hangers to suit timbers 150mm deep and above are manufactured with their H dimension 10mm undersize to allow for notching to provide a fl ush ceiling line.3. In order to achieve the stated safe working loads all masonry must be fully cured and a minimum of three block course (675mm) must be constructed above hanger. Where no masonry exists above see Cullen’s RA or RB-JH.4. R dimension stands for return tab only and does not provide restraint.

** 2.8N/mm², 3.8N/mm² and 7.0Nmm² indicate masonry crushing strength.

RA Installation

Stage 1 - Pre-Fitting

Ensure joists just fi t between the walls.

If using I-Joists and they are too long, trim to fi t.

Position joist against location tab.

Pre-fi x RA to each end of pre-cut joist, nailing through slotted holes in baseplate and side fl ange only, as shown.

Slide to opposite side of slots to provide full 6mm adjustment on wallhead.

Always pre-fi x hangers at ground level or on scaffolding.

Stage 2 - Adjustment

Locate assembled joist on wallhead allowing equal adjustment at both ends.

Adjust each end by tapping with a hammer until return fl ange is correctly positioned tight against blockwork.

This stage provides a maximum horizontal adjustment of 12mm and suits blockwork built to BS5606:1990 Accuracy in Building.

Ensure return fl ange abuts masonry.

Stage 3 - Final Adjustment

Fully nail using 3.75 x 30mm square twist nails.

DO NOT apply any load to joist prior to RA being fully nailed.

The performance of RA Range is not width or depth dependant, therefore, the above values can be attributed to all sizes of joist product (195 to 302mm deep). The S.W.L fi gures are applicable up to, and including, a 6mm gap between the end of the joist and the inside of inner leaf of masonry.

Refer to table below for mortar curing times to allow RA range to be used as a working platform.

Page 30: Uk Truss Brochure

The FMH masonry hanger evolved through regular requests for a connector capable of supporting loads for multiple and irregular depth connections. In order to maximise the load carrying capacity at a single point it was necessary to increase the masonry support fl ange to allow the load to be dispersed over a larger surface area.Adopting one standard design which is both width and depth variable without performance penalty increases the design fl exibility of the product.

ADVANTAGESFlexibility of design.

MATERIALBeam support – 3.0 - 6.0mm mild steel [A] depending on hanger widthMasonry fl ange – 4.0mm mild steel [B]Finish – Zinc undercoat with an organic bituminous top coat to BS 5268-3:2005Alternative fi nish on request - hot dipped post galvanised to BS5729

IFI hangers can be manufactured in depths of 190mm, 215mm, 230mm and 295mm, as demonstrated, to accommodate I-Joist depths ranging from 195mm deep to 302mm. Hanger widths available range from 39mm to 100mm.

I-Joist to I-Joist

Using standard face fi x hangers, in an application where 90mm or less is the required spacing between joists, will cause the side fl anges to overlap or ‘clash’.

Using IFI hangers in this application will eliminate overlapping or ‘clashing’ of the side fl anges.

GENERAL NOTESAll I-Joist to I-Joist safe working loads are based on I-Joist headers with fully nailed backer blocks (refer to I-Joist manufacturer’s fi xing details).No web stiffeners were used to achieve safe working loads stated (I-Joist manufacturer may require web stiffeners).Safe working loads quoted are the maximum hanger capacity.When multiple joists are used they must be connected together to act as a single unit (refer to I-Joist manufacturer’s fi xing details)Safe working load allowed without backer blocks is 1.8kN up to 245mm deep joists and 1.4kN on joists greater than 245mm deep.Where fi xings are required to a steel beam a minimum of 38 x 89mm timber wallplate must be fi xed to the steel and the TFI fi xed to this using the top nails and the upper face nails only (8no. nails in total) fi g 1. & fi g 2. In this situation the safe working load is 4.2kN.Where fi xings are required directly to a steel beam the TFI can be shot fi red directly into the steel beam (maximum steel thickness 12mm) using 4no. X-EDNI16 Hilti nails or equivalent, into the top fi x hanger top fl anges (2no. fi xings per leg). In this situation the safe working load is 6kN.

Cullen has created a lightweight yet high performance product which accommodates various incoming girder widths. For instances beyond the HGG performance band Cullen has developed a standard high load design (VHGG) to accommodate loads up to 40 kN at various widths. The adoption of this semi-standard concept will help eliminate costly bespoke design charges.

ADVANTAGESVHGG can accommodate loads up to 40kN.All bolts/washers supplied with hangers.

LedgerLok - Procedure For Designing Connections of Multiple Girder Roof-Trusses

Top Chord Dead Load (kN/m² on slope) 0.685

Top Chord imposed (snow) load (kN/m² plan)

For pitches ≤30˚ 0.75

For pitches >30˚ 0.75 [(60 - pitch) / 30]

Bottom chord dead load (kN/m²) 0.25

Bottom chord imposed (storage) load (kN/m²)Water tank loads as BS5268-3 0.25

Design assumptions:The connection details given are applicable to trusses with pitches between 15˚ and 45˚ and supporting the following loadings:

Design procedure:Step 1: Design the girder truss in accordance with the software provided by your system-owner.Step 2: Determine the appropriate LedgerLok fastener length and the spacing required in the girder truss bottom chord for the relevant return span of the incoming trusses using Table 1 for 2-ply girders and Table 2 for 3-ply girders. The layout of the fasteners is to be as per Figure 1 for bottom chord depths ≤97mm or as per Figure 2 for bottom chord depths >97mm.Step 3: Determine the LedgerLok fastener spacing and layout required in the girder truss top chords and webs based on Figure 3 for member depths ≤97mm or based on Figure 4 for member depths >97mm.

HMT-50 In-situAccommodates maximum differential movement of 75mm

The HMT is a higher performance wall tie that allows the differential movement in medium to high-rise structures to be accommodated.

The HMT range is a two-piece design with the channel section being fi tted plumb to the structure and secured with two standard wall tie nails. The tie element interlocks and provides a sliding arrangement which doesn’t cause the historic binding problems normally associated with dovetail type ties when used in timber frame.

ADVANTAGESAccommodates maximum differential movement of 75mm.

MATERIALHMT - 1.2mm austenitic stainless steel.

HMT - High Movement Wall Tie

InstallationStage 1

Stage 2

Nail channel into wall panel using slotted nail hole only, with nails provided (3.35 x 50mm stainless steel annular ring shank).

Position nail to bottom of slot to allowfor full 30mm vertical adjustment if required.

Allow adequate space above masonry to hammer fi x.

Position channel by lightly tapping with a hammer until channel is in correct position at its lower extremity.

Once channel is in position fi x the top round hole into the wall panel using nails provided. (Ensure channel is fi tted plumb).

Position tie into channel between the high & low markers. Build up next row of masonry.

Ensure both nails are fi tted

Applications and Installation

UWV - Universal Wall Vent

The UWV is used to drain cavity trays at lintels and to provide ventilation to cavity walls in timber frame construction.

The UWV is to be installed in orientation (A) when used as awall vent and in orientation (B) when used as a weep vent.

ADVANTAGESDual function ensures both positive drainage and ventilation.Grille design resists wind driven rain and protects against insect penetration & clogging.Quick & easy to install.Maintenance free.

The UWV is available in a variety of colours to matchsurrounding mortar, grey (GR), brown (BR), black (BL), blue/black (BB), buff (BU), white (WH) & terracotta (TE).

All are supplied in boxes of 50 units.

••

••

Wall vent orientation (A) Weep vent orientation (B)

To provide drainage to lintels above all windows & doors install the UWV (weep vent orientation B) securely into the vertical mortar joints of the outer leaf of masonry above the lintel at 450mm maximum centres, providing at least 2 per opening, ensuring that the grille is free of mortar.

UWV installed above metal lintel

Install the UWV (weep vent orientation B) into cavity trays to prevent water build-up by allowing the discharge of any collected moisture. It is recommended that 1 weep vent is installed per cavity tray to ensure that moisture is effectively diverted onto the lead fl ashings.

UWV installed into cavity tray

The UWV provides ventilation to cavity walls to dissipate any moisture that may collect. The UWV should be installed (wall vent orientation A) into vertical joints of the masonry outer wall at 1500mm centres both at eaves level and below the DPC level.

Ensure this end is notobstructed by mortar tomaintain requiredventilation

PFS - Pre-Formed Strap

The PFS is a single piece, 1.5mm galvanised steel strap, designed to provide enhanced performance and greater fl exibility of use.

It exceeds the performance of the traditional 30 x 5mm lateral restraint strap. When you combine its improved strength, lighter weight, increased corrosion resistance (Z600 material) and ease of use, specifi cation of the Cullen PFS strap becomes the preferred choice for all restraint strap applications.

ADVANTAGESIts shallow depth allows it to run on the surface of traditional timber joists/ trusses without the need for notching.Lighter weight.

MATERIAL1.5 mm galvanised mild steel – Z600Also available in 1.2 mm austenitic stainless steel.

NP - Nail Plate

The NP allows the connection of timber joints by using perforated plates on each face of the joint, nailed together through the jointed timber. For fi xing the NPs we suggest 3.75 x 30mm square twisted nails, hand fi xed through the pre-stamped nail holes.

MATERIAL1.0mm galvanised mild steel - Z275•

Nail plates available to order in 80, 100, 150, 200, 250 and 300mm widths and any length in increments of 100mm.

DESIGN AND SIZING OF NAILING PLATES FOR TIMBER TO TIMBER JOINTSAll timber to timber joints for use on trussed rafter roofs must be designed in accordance with guidelines given in BS5628 Part 3:1998.Careful consideration must be given to end and edge distances, as no nails can be fi xed within these areas without the possibility of the timber splitting, so no load carrying capacity should be taken for these areas. A nailing plate should be positioned on each side of the joist, with nail fi xings from alternate faces to avoid nails clashing. Care should be taken to ensure equal numbers of nails are fi xed from each side.

TYPICAL JOINT ARRANGEMENTSOn butt joints fi x nails only in hatched area of timber.BS 5268 Part 3: CI 6.5.6 states that irrespective oftheoretical design requirements, the minimum dimensions ofthe nailing plate should be taken as:WIDTH = NOT LESS THAN 0.7hLENGTH = NOT LESS THAN (0.8h + 80mm).Where h is the depth of the member in millimetres.Careful consideration should be applied to butt joints carryingmoments, where polar moment design checks should be applied.

TYPICAL JOINT ARRANGEMENTS – Heel Joints Additional Design/Detailing RulesBS 5268 Part 3: CI 6.5.6 states that irrespective of theoretical design requirements, the minimum bite of the nailing plate into a chord member should be taken as the greater of the following:

(0.2L + 15)mm Where L is the overall size of the nailing plate in millimetres (mm) measured at right angles to the chord member30mm, or 0.25h Where h is the depth of the member in millimetres (mm).
