Abstract
21,706. Hansen, H. Oct. 1. Moulding structures in situ.-In apparatus for moulding concrete partition-walls in situ, pairs of vertical posts a, which may be in sections bolted together, are spaced apart and support pivoted levers c, g, which have projections e, f to support the moulding-boards k and hold them in place. The boards are raised as the work proceeds by cords passing over pulleys on the upper ends of the posts, and in rising push aside the levers c, which move in guides i and automatically fall down when released. Fig. 3 shows a modification in which the levers g are dispensed with, the levers e being formed with sloping projections p to engage the boards k which are grooved to take these projections.
