The BAT S.P.H. Joist Hanger is a single piece

timber to masonry hanger.

Straddle Type ‘ST’

(‘ST’ Type is two Standard Joist Hangers joined

together with Jointing Plate), fixed by riveting.

Return Type ‘R’

(‘R’ Type is a Standard type ‘S’ with Return

Plate added), fixed by riveting.

75mm

Standard Type ‘S’

Both the ‘R’ and ‘ST’ Type enables the hangers to be

positioned accurately whilst the masonry is built above.

How to Order/Specify BAT

SPH Joist Hangers

TYPE ‘S’ –

Please state dimensions of joist

(a) depth

(b) width

Minimum box quantity dependent on hanger size.

TYPES ‘R’ & ‘ST’ (made to order) –

Please state dimensions of joist

(a) depth

(b) width

(c) top flange (to suit wall width)

Quantity made to order

The back face of hanger must be flush

against the wall.

The timber joist should be square cut and

butting to the back face of the hanger

(maximum permitted gap 6mm).

A minimum height of 675mm of set masonry

must be in position above the supporting

flange before any load is applied.

Fixing: Nail to the joist through the nail holes

in each side gusset with BAT 3.75 x 30mm

long square twisted sherardised nails.

It is recommended that joists are notched

for the base of the hanger to achieve a level

surface for plasterboarding.

Type ‘R’ and ‘ST’ provide additional location

and alignment during construction.

Installation Requirements

Concrete, etc with provision for Nailing or Bolting.

How to Order/Specify – BAT Maxi Speedy

- Manufactured from 1.5mm thick pre-galvanised mild steel to

BS EN 10142 : 1991, DX51D + Z275.

- Available in 6 types: MS240; MS335; MS380; MS500; MS560

& MS620.

- Nail hole diameter: 4.5mm Bolt hole diameter: 14mm

- Available widths: 38, 50, 63, 75, 100mm (122 + 150 for

Design Features

Fixing: use BAT 3.75 x 30mm long square twisted sherardised nails.

M12 Bolts or Coach screws as specified by fixing manufacturer.


Steps to specify requirements:

1. Joist dimensions:

Double joist depth and add joist width,

ie for joist 225 deep x 38mm wide then:

225 (d) + 225 (d) + 38 (w) = 488mm.

2. The Maxi Speedy blank length

must be less than total calculated

in step 1, therefore select MS38038

(not MS500 as the joist hanger

would stand proud).

BAT straps are manufactured in two types. The

M305 to provide horizontal restraint and Standard

to provide vertical restraint against wind pressure

and uplift forces.

OrderingWhen ordering quote the overall length and distance

of bend/twist from END of strap. eg. overall length,

bent at 100mm, bent at 250mm, twisted at 400mm.

If in doubt, provide sketch.

Anchorage of gable end to roof

structure, M305.

Floor level straps M305 notched

into parallel joists. Note: Gaps

between masonry and adjacent

joists must be packed.

Fixing to wall plate and wall with

one bend.

Floor level straps M305. 150 x 650mm

long once bent and once twisted fixed

to perpendicular joists.

Note: Turn down of the strap must

be in contact with the masonry.

M305 STRAPSTANDARD STRAP

- The straps are manufactured from pre-galvanised steel strips

with zinc coated edges to BS EN 10142 : 1991, DX51D + Z275

or stainless steel to BS EN 10088-1 : 1995 : 1.4301.

- Nominal Dimensions

M305 - 27.5 x 5.0mm

Standard - 27.5 x 2.5mm

- Hole diameters are 6mm and they are holed at 12.5mm

grouped in threes, diagonally across the width of the strap.

Design Features

The installation of restraint straps must comply with the current

Building Regulations, British Standards BS 5628 : Part 1 and

Part 3 and BS 8103 : Part 1, as well as NHBC recommendations.

When straps are being fixed across joists or trussed rafters

which are parallel with the wall, and where there is a gap

between the wall and the first joist or truss, the gap must

be packed. Noggins must be provided between each joist

or truss.

Fixing for M305 and Standard Straps: use either

No 12 x 50mm wood screws or 4.00 dia x 75mm corrosion

resistant nails.

For stainless steel straps, stainless steel fixings must be used.

Herringbone Joist Struts

Truss Clip- Manufactured from 0.9mm thick pre-galvanised


- Hole diameter: 4mm Height: 117mm

- Available in 2 sizes:

- Other thicknesses of trussed rafters may be

fixed using pairs of BAT Framing Anchors,

type MFAAL and MFAAR.

Fixing: use BAT 3.75 x 30mm long square

twisted sherardised nails.

All nail holes must be filled.

Safe Working Load – 1.3kN uplift.

The timber wall plate must be securely held

down onto the supporting masonry.


Herringbone Joist Struts provide stability to floor joists. Expamet Herringbone Joist

Struts significantly reduce labour content in fixing strutting on site.

The Bat Truss Clip eliminates the disadvantages

of skew nailing trussed rafters to timber wall

plates; damaged connector plates; split rafters

or wall plates.

The provision of eaves vents to limit condensation risk is a

requirement of the Building Regulations.

Expamet expanded stainless steel is used over the vents to exclude birds

and insects. This mesh is an economical material for the purpose. It is

readily adaptable to various eaves details, is light in weight and easy to

handle on site. Coils of mesh in convenient dispensers make site work

easier and avoid wastage.

Stainless steel nails or staples should be used for fixing the eaves

vent mesh.

Bat Timber Decking Clips enable the installation of

deckboards to be quick and simple.


Design Features

A Note on Butting Deckboards

Unless your deck size uses standard timber lengths, you will need to stagger boards to cover the

deck area. For safety and to prevent movement, staggered deckboards must meet over a joist.

Nail two short lengths on either side of the joist, for an adequate skew-nailing surface.

Deckboards can be laid in a number of different ways. It is important that you decide on the

deckboard layout before assembling the support joists, as some patterns will affect the spacing

and number of joists, e.g. a double joist will be needed for a chevron style layout.

- Easy to install deckboards - clip one side and skew-nail fix

the other side.

- Ensures an unmarked deck surface

• no visible nail holes • no water pools

• no hot spots • no rust stains

- Galvanised for corrosion protection.

- Suitable for use with complex patterns.

1. Fasten both edges of the first deckboard to each joist by skew-nailing with hot-dipped

galvanised nails.

2. Set the deckboard on edge and use the locator prongs to position the timber decking clip tight

against the bottom of the deckboard (within 50mm of each joist - but not on the joist itself ).

Fasten with 30 x 2.65mm dia hot-dipped galvanised nails. These must be fitted as tightly as

possible to the bottom of the deckboard.

3. Place the deckboard so that the timber decking clips slide tightly under the previously

anchored deckboard.

4. Ensure the new deckboard sits tight against the anchored deckboard.

5. Skew-nail the front edge of the deckboard into the top of each joist. The deckboard is now

tightly anchored on both edges.

6. Repeat the above steps for each board on the deck and anchor the final edge by skew-nailing.

The result is a smooth, unmarked deck surface with a longer life and easier maintenance.

Board Thickness (mm) Nail size (mm)

EXPAMET

For In-Line Wall Expansion JointsFor Single Walls

1. Build one side of expansion joint wall, building in Expamet Cobra Movement Ties at maximum 450mm centres (every other blockcourse) with the non-sleeved end of the tie fully embedded up to the location lugs/sleeve stop (see Fig. 1). Position the tie in the centreof the wall to allow for the expansion foam strips either side (see Fig. 2).

2. When the first wall has set, build the second side of the expansion joint wall to the desired gap (10-16mm).

3. The 1.2m intumescent foam must always be placed to the inner side of the wall. Butt joint the second 1.2m length of intumescentfoam above the first and complete the full wall height up to 2.4m. Additional Expamet Cobra Movement Ties will be needed if the wallexceeds 2.4m high.

4. When the wall has set, compress and feed the 2.4m outer foam into the gap from top to bottom cutting off any surplus foam. Rebate approximately 6mm in from the external face of the wall.

5. For External Walls (additional protection) if joint is open to direct moisture use a silicone mastic seal fromtop to bottom of the wall joint, the standard foam will act as the backing for the mastic joint.

Cavity Walls

Fix as above but stagger Expamet Cobra Movement Ties (225mm vertical offset between leaves) to allowa cavity wall tie to be built at 225mm centres.

For Column or 90° Wall Expansion Joints1. Drill and fix the 5 No. Expamet Cobra Movement Ties to the column or existing wall at 450mm maximumcentres leaving the coachscrew lightly tightened to allow the tie to slide into position easily. When thecourse is level tighten up the coachscrew fully. Repeat to full wall height.

2. Build the new wall allowing 10-16mm gap between new and existing wall/column.

3, 4, 5 as above

Repair of Existing Failed Wall Expansion JointsRake out the old joint from the wall, compress and push in the standard or intumescent foam strips into the gap from top to bottom.Rebating approximately 6mm from the external face of the wall.

If the joint is exposed to direct moisture use a silicone mastic seal from top to bottom of the rebated gap. The foam will act as thebacking for the mastic.

Reinforced brickwork is preferable to unreinforced in all types of building

because steel reinforcement adds tensile strength to the inherent compressive

strength of this traditional construction method.

Reasons why you should select stainless steel Exmet for

reinforcing brickwork.

- Exmet is a length of expanded steel mesh with continuity of steel throughout.

- Exmet has no joints, welds or interweaving to fail under stress.

- Once mortared into brickwork the diamond-shaped meshes are anchored

immovably so that the reinforcement cannot slip under tension.

Exmet Reinforcement

Stainless steel Exmet for brickwork

Stainless steel Exmet is manufactured from stainless steel to BS EN 10088-1 : 1995 : 1.4301, (grade 304/S15).

Exmet is easily cut on site with tin snips.

In stainless steel for brickwork,

blockwork and partitions

(conforms to the requirements

of BS5628: Part 3: 1985).

Reinforcement at special points

Past experience has shown that Exmet is particularly desirable in footings, sleeper walls, cornices and parapets; also over

openings for windows, doors, etc.

Solid and hollow walls

Normally the brickwork alone is of sufficient strength but in circumstances where greater strength is required to allow for

uneven settlement and movement in buildings it is desirable to use Exmet reinforcement in the joints. Exmet not only assists

in distributing the loads evenly but reduces the possibility of cracking so common in these conditions.

BUILDERS METALWORK

28

Location of the reinforcement in brickwork and blockwork

When laid flat it should be set in the bed joints with its outer edge about 25mm fromthe face of the masonry.

Where it is necessary to join the strips at ends, an overlap of not less than 75mmshould be provided.

In all cases the reinforcement must be completely embedded in the mortar.

Using stainless steel Exmet in brickwork and blockwork

Effective quantities of reinforcement

Exmet should be placed in every third brickwork bed joint or every blockwork bed joint.

Combinations of different widths of Exmet may be used to suit any wall thickness.

Wall Starter & UniStarter Installation

• Suitable for both metric and imperial brick/block sizes.

• Integral ties are designed to tie into every (225mm deep)

block course or every third course of (75mm deep) bricks.

• Each pack contains two 1175mm lengths. Slotted holes at

each end allow easy connection of one length to the next.

• Full fixing instructions and all necessary coach screws,

washers and plugs are provided. Only 5 fixings are

needed for the two lengths (Type 120 and 185 Wall

Starters are supplied with 10 fixings). The only tools

you need are: spirit level, drill (with 10mm masonry bit)

and 10mm spanner.

• Miscoursing of up to 50mm can be solved by simply

bending integral ties to suit. This will reduce the length

of ‘built-in’ tie, but it still meets relevant test criteria.

• All products are designed to allow up to 10mm vertical

movement.

• If the upper end of the product extends past the top line

of your wall, use tin-snips or a hacksaw to cut off the

excess and attach using the remaining top fixing hole.

• Align the centreline of the UniStarter with the centre of

the new wall. Align the flanged edge of the Wall Starter

to the front or back of the new wall.

• For cavity walls, each leaf will require a separate starter.

• All external walls require a 10mm wide weather seal

to be fitted between the product and the existing wall.

• In exposed locations (or to meet Local Authority

specifications), a vertical DPC should be cut into the

existing wall prior to fixing the product.
