Below are examples of commonly used connections.

Simple connection

Bolted at an intersection with end plates, with the possibility of stiffener plates behind. If you have beams that are different depths – these can be made flush top or bottom to suit your needs.

FULL Spliced connection

Used with HSFG bolts – this connection is used to split beams into smaller, more manageable sizes.

Angle

To connect to brickwork or concrete, an angle connection is simply drilled with slotted holes.

Box Frame

This structure is often used when a wall is removed. It involves incorporating two columns with a ground and header beam.

Simple connection

Bolted where two beams meet with end plates – with the possibility of stiffener plates. On differing sized beams, these can be flush top or bottom.

 

Roof structure

A typical Mansard type roof frame – supplied in smaller manageable parts for easier construction.

Goalpost

Similar to a Box Frame – it involves incorporating two columns with a header beam. The header beam can be spliced if too long or heavy to erect in one.

Flitch beam

A compound beam often used in house construction. A flitch plate is predrilled and then inserted between two timber beams when on site – these three layers are held together with bolts.

Seating plates

Plates can be welded to the top or underside of beams – centrally or offset. This is typically done to support brickwork or timber framing.

Butt joint

A splice for connecting two lengths of steel to aid carrying and installation. This is not a full splice and will have to be agreed with an engineer.

Spaced beam

Used for where height is restricted – a pair of beams are bolted together with either tubular or PFC spacers.

Bearing Plates

Supplied either loose or welded to a beam to spread load bearing at each end.

Seating angle

Used to support metal decking or pre-cast concrete floor planks – can be fixed to either one or both sides of a beam.

Raking end

A beam end cut to match the pitch of a roof timbers.

Simple connection

Bolted at the intersection with one beam, notched with a welding end plate. Where joists are of different depth, these can be flush top or bottom to meet your requirements.

Base Plate

This plate is welded to the bottom of a column or post to allow fixing to a foundation or concrete pad. This is a regular practice to allow a gap to the underside for dry packing/grout.
