Superhangers for Supporting Joists from Walls and Beams
Available in full compliance with BS 6178:Part 1:1982. (Joisthangers for building into masonry walls of domestic buildings).
Type W: The ‘build in’ type provided with a specially ribbed top flange for building into the mortar joints of a masonry wall.
Type H: Similar to Type W but with the addition of a return flange to hood over a wall or structural member.
Type FF: The face fixing for fastening to a vertical surface through holes located in the back plate.
Straddle Type (ST): A double version of Type W to support joists either side of a wall or structural member.
Superhangers are manufactured from galvanised steel sheet to BS2989:1982, and are available upon request to BS6 178:Part1:1982. In type G.600 heavy galvanised finish.
They are fully pressed from 2.5mm thick material with no welding or riveted joints whatsoever and with uniformity of strength, quality and finish always guaranteed.
Superhangers are suitable for masonry, having a minimum crushing strength of 2.8 Newtons/mm and above. They are economical in cost, easy to handle to fix, and neatly packed in boxes for convenient storage.
Lightweight Joist Hangers
Beamfix Lightweight Joist Hangers for Medium Duty Applications
Ultimate load per hanger: 20.58 Kilo-Newtons. Eurometals’ Beamfix lightweight joisthangers are manufactured from 1.0mm thick galvanised mild steel to BS2989:1982. They provide a cheap and efficient method for connecting medium duty timber joists of various widths and from 125mm deep and above.
Eurometals’ Beamfix lightweight joisthangers offer considerable timesaving in on-site labour as their side straps are easily bent by hand around the supporting member and the connection quickly secured by nailing with 3.75mm x 30mm sq. twisted sheradised nails. Non-standards with extended side straps can also be supplied.
Please note that the ultimate loads stated for the components illustrated were obtained from destructive hydraulic testing with all nails fixed. An appropriate factor of safety should be applied in order to determine safe working loads for design purposes.
Safe Working Loads
Actual safe working loads for hangers depend on ultimate on-site loading capabilities and factors of safety applied.
Since the ultimate on-site loading capability of any joint hanger is dependent on the strength characteristics of its associated building materials, and the method of fixing employed, considerable variations are possible.
For general information, a programme of destructive testing was undertaken on hydraulic test apparatus in order to determine the ultimate structural capability independent of variable site conditions.
With flanges securely clamped in position, and the loading applied to a timber beam supported by two 165 deep joist hangers, the following results were recorded:
|Hanger width (mm)||44||50||75||100|
|Ultimate load per hanger (KiloNewtons)||24.60||25.39||28.87||30.85|
|Nominal Timber Depth||100||125||150||175||200||225||250||275||300|
|Internal Superhanger Depth||100||125||140||165||190||215||240||265||290|
