PREFABRICATED FORMS FOR A SEWER

摘要

The formwork system comprises two lower haunch form members (10) with holes (12) to receive anchor bolts in the bottom slab, wall panels (25) combined sequentially up right, two upper haunch form members each having (1) support arms for mounting holding members (3) (2) on both sides, slab panels (20) mounted on upper beams (30) each telescopically flexible in length. The prefabricated form members are easily assembled at construction sites to remove the need of skilled workers and expedites the work.
