Space Creation In Existing Buildings

What is Pynford Beam and the Pynford Support System?

Pynford beams at high level may bear on the brickwork at either end or may be supported by concrete columns at the ends and/or in intermediate positions. The columns in turn may be supported by new foundations or spreader beams that redistribute the loads at a lower level to avoid altering existing foundations.

The existing wall is cut away at intervals and Pynford Stools inserted along the line of the required beam. The lower section of the wall and its foundation still support the load so needling and shoring is unnecessary.
When all of the Pynford Stools are in place the remaining sections of wall between them can be safely removed. At this stage the loads and stresses are still largely unchanged.
The reinforcement, designed and detailed for specific loads and spans, is then fixed through and around the stools, forming the normal cage. If columns are required to form the multi-storey frames starter bars are also fixed at this stage.
The form work is fixed and the beam is concreted. The wall and any piers beneath are then removed creating space.

 Load calculated by Pynford engineers is jacked into the stool to ensure settlement criteria is met.
