Holder frame for building riser during fixing - has articulating traverse beam on legs allowing post bracing from irregular ground

摘要

The holder frame has two struts (2a,2b), the top (5) and bottom (6) ends of which are bevelled to press onto the inside and outside faces of the riser and onto the ground respectively. The traverse beam (3) is fixed laterally to the struts and can articulate on them. When the post to be supported is a single one, not braced in any direction, a support leg can be added to the holder which is fixed articulating to the centre of the traverse and has its base bevelled to sit squarely on the ground.
