Adjustable divided mould for concrete bend - has double shell with overlapping faces opposite hinge pin

摘要

A mould for a concrete bend with an outlet opening in two of the faces nominally at right angles, has an inner wall (10) and an outer wall (4) forming two mould halves which can be swung about a hinge (5) to vary the angle between the two faces. The outer edges (7) of the two outer halves move over the inside of a curved member (7) forming a port of the mould. The inner mould halves have curved forming one outer face of the mould. These two curved halves overlap at the middle. In this region, the two curved inner halves are flanged (14), with holes (15) for securing bolts. The mould halves are swung by an external actuator cylinder (6) or spindle.
