Rectangular panel assembled concreting formwork - has anchor holes at corners and away from them, for tiered panels (BR 23.12.80)

摘要

A frame structure, and form skin with apertures for penetration by anchors located on two opposite edges, are incorporated in a system of formwork with rectangular panels. On each of these two edges there is one aperture (1) directly in one corner of the panel, and another (2) at an interval from the other corner. The apertures pref. have a tube-type sheathing (6,7) round them, terminating flush with the frame structure (3,4) on the side opposite to the form skin. With form panels arranged on top of each other, this enables both the top and bottom ones to be held with a single row of anchors in the horizontal joint area, whether they are upright or flat.
