Masonry HangersMasonry Hangers for Solid JoistsSFJC Safety Fast Joist CapThe SFJC is an innovative and unique product which enables a safe, practicaland robust solution that satisfies the requirements of ‘Approved Document B &L’ of the Building Regulations.The SFJC is designed to be used where timber joists are built into a masonryexternal wall and eliminates the air leakage problems associated with shrinkageof timber joists. It also provides resistance to fire for up to 60 minutes whengaps are filled in with mineral wool.CERTIFICATE No 04/4170••••SFJC305/50, SFJC305/100 and SFJC225/100 models accomodate a largerange of joists types and sizes.SFJC225/50 specifically designed for 50mm solid sawn joists up to225mm deep.Air leakage around the joist end is eliminated.Wide face flanges provide an air tight seal.MATERIAL: Black Polypropylene.The SFJC does not provide any lateral stability to the joists during constructionphase. It is therefore necessary to install temporary bracing in accordance withthe joist manufacturers instructions and/or standard construction practice, toensure temporary stability of the floor joists.• Place floor joist onto wall and adjust to ensure correct bearing at each end.• Lift the floor joist and install SFJC over the end of the joist, ensuring theSFJC face flanges are tight against the inner face on the masonry wall.SFJC225/50: SOLID SAWN JOISTS• Solid sawn joists up to 50mm wide and 225mm high can be installed directly into theSFJC225/50.SFJC305/50 & SFJC225/100: SOLID SAWN JOISTSSFJCPATENT GB2392928,GB2393459Typical SFJC225/50 Installation••Solid sawn joists up to 50mm wide and 300mm high can be installed directly intothe SFJC305/50. For narrower joist widths use the wedge cut outs to pack thejoist.Nail in place with 2 No 3.75 x 30mm square twist nails per plate.SFJC305/100 & SFJC225/100: SOLID SAWN JOISTS• Steel joist plates slides into the slots within the SFJC and are fixed to the top andbottom of the floor joists.• Nail in place with 2 No 3.75 x 30mm square twist nails per plate.• Install horizontal restraint straps at maximum 2m centres• Nail to the timber joists with 8 No 3.75 x 30 square twist nails.• Build up masonry between SFJC and continue with wall construction.• Ensure all joints between the masonry and SFJC are fully filled with mortar.• With the SFJC305/50 check the tightness of the wedges once wall is completed.• If necessary, hammer wedges in tight and adjust retaining nail.• Also if necessary, fill the void around the joist with mineral wool or expanding foam.Model No. Dimensions (mm) Hanger Dimension (mm)Solid Sawn Joist Sizes(mm)Width Height Width Height Web Width HeightSFJC225/50 50 225 - - - 50SFJC225/100 100 225 - - - 100SFJC305/50 50 305 up to 50up to 50up to 302 9 to 12SFJC305/100 100 305 up to 100 up to 100up to 225up to 300Typical SFJC305/100 InstallationTypical SFJC305/50 InstallationCatalogue C-UK10 © 2010 SIMPSON STRONG-TIE COMPANY INC.1.2.2 No SFJC Wedges supplied with each SFJC305/50.2 No Steel Joist Plates supplied with each SFJC305/100 and SFJC225/100.18
Masonry Hangers for Solid JoistsJHM/HJHM Masonry Supported Joist HangersJHMs and HJHMs are one piece non-welded joist hangers for supporting timber joists,beams and trussed rafters from masonry walls.• Built-in inspection slot at the base of the hanger to aid inspection from the ground.• HJHM: Heavy duty masonry hanger for higher load carrying capacity.• Top flange provides widest area in contact with masonry support allowing superiorperformance. Embossments on JHM stiffen top flange and holes allow improvedmortar keying.• JHM side flange on deeper hangers is much higher than traditional style, providinggreatly enhanced resistance to joist rotation.• Regularised Timber: we have added new sizes to our JHM range to suit regularisedtimber. Use 47mm or 91mm width hangers for this new application.MATERIAL:JHM129-150Masonry HangersJHM and HJHM: Pre-galvanised mild steel.INSTALLATION:• Use all specified fasteners. See "General Notes" (page 12).• Set hanger back flange tight against block wall when built to desired level, thencontinue with additional courses to complete wall height. Joist should be tight intoback of hanger when possible. Maximum gap permitted is 6mm.• MINIMUM 3 COURSES OF SOLID BLOCK (675MM MASONRY) REQUIRED ABOVEHANGER WITH MORTAR FULLY CURED BEFORE APPLYING LOAD.• Do not stack blocks or heavy loads on the joists during construction unless thejoists have additional support to take the full load of the blocks vertically andhorizontally.• The JHM joists hangers can be fixed to steel beams by means of power actuatedfasteners.• The shot-fired pins must be installed by a qualified person in accordance with themanufacturer’s installation requirements.HJHMOPTIONSCatalogue C-UK10 © 2010 SIMPSON STRONG-TIE COMPANY INC.• Return configuration provides additional support by wrapping around three sides ofthe block.
