Formwork for casing open ended cells esp. concrete garages

摘要

The formwork has outer sideforms supported on transverse guides so that the distance between them can be varied. An inner former (15) sits on a prefabricated soffit form which can be set in at least two vertical positions on a frame (30) w.r.t. the side and end walls. The sidewalls (24,24') and rear wall components (26,28,26') of the inner former are adjustable in position to allow various widths of central void to be cast. By adjustment of the positions of the side walls and height and width of the inner former a range of sizes and section thickness can be mfd.
