Joist Hanger is a single piece timber to masonry hanger. 75mm Design Features Installation Requirements - Single-piece, non- welded construction. The back face of hanger must be flush against the wall. Standard Type ‘S’ - Wider masonry flange to increase loadings on masonry of compressive strength 2.8N/mm2 and greater. - Manufactured from 2mm thick pre-galvanised mild steel to BS EN 10142 : 1991, DX51D + Z600. - 75mm load bearing surfaces. - All hangers 150mm deep and over are manufactured 10mm less to allow for notching and regularisation of timber joists. 04 - Gusset nail holes are non coaxial. - Standard available widths 38, 44, 50, 63, 75, 100, 125, 150mm. 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. Return Type ‘R’ (‘R’ Type is a Standard type ‘S’ with Return Plate added), fixed by riveting. Type ‘R’ and ‘ST’ provide additional location and alignment during construction. - Hangers to suit Ι joists and extra wide sizes (150mm - 225mm) available to special order. Price and delivery on application. 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) – If you require advice on applications of joist hanger types, Expamet’s Technical Department will be pleased to assist.

Design Features - 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. Installation Requirements 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) 28 - 34 65 x 2.65 35 or greater 75 x 3.75 Alternatively, comparable corrosion resistant screws with pilot holes can be used. 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. 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. 23 CERTIFICATE No. 99/3574 EXPAMET Wall Movement Joint System For professional control of movement in masonry.

Certificate No. 99/3574. Instructions For In-Line Wall Expansion Joints For Single Walls 1. Build one side of expansion joint wall, building in Expamet Cobra Movement Ties at maximum 450mm centres (every other block course) 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 centre of 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 intumescent foam above the first and complete the full wall height up to 2.4m. Additional Expamet Cobra Movement Ties will be needed if the wall exceeds 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. 24 5. For External Walls (additional protection) if joint is open to direct moisture use a silicone mastic seal from top 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 allow a cavity wall tie to be built at 225mm centres. For Column or 90° Wall Expansion Joints 1. Drill and fix the 5 No. Expamet Cobra Movement Ties to the column or existing wall at 450mm maximum centres leaving the coachscrew lightly tightened to allow the tie to slide into position easily. When the course 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 Joints Rake 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 the backing for the mastic. BUILDERS METALWORK 450 2400 Intumescent foam to inside. Fig. 2 225 Fig. 1 Push standard foam into outer face of wall after wall has set.

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 is easily cut on site with tin snips. 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. 27 Using stainless steel Exmet in brickwork and blockwork 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 from the face of the masonry. Where it is necessary to join the strips at ends, an overlap of not less than 75mm should be provided. In all cases the reinforcement must be completely embedded in the mortar. 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 Starters/UniStarters (5 screws, plugs and washers) Ref: WSF Wall Starter & UniStarter Installation 30 • 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. BUILDERS METALWORK Multi-Starters Featuring a ‘turn-n-slide tie’ to accommodate all sizes of brick/block. The Multi-Starter is suitable for all wall widths from 60mm-250mm.
