Partition wall
Highly fluid ready-mix concrete seeps into the gap between the sponge mold and the slab bottom (formwork), causing the sponge mold to lift. Furthermore, labor costs are currently incurred for chipping away the concrete that leaks out after it has hardened. [Solution] By using the present invention product instead of the conventionally installed rafters, it is possible to prevent the intrusion of fresh concrete into the slab bottom (formwork) and the bottom of the sponge mold, thereby preventing the sponge mold from floating. Previously, rafters were lined up to secure the pouring height (slab height) of the fresh concrete, but by using the present invention product, the pouring height of the fresh concrete can be secured, and because it adheres closely to the slab bottom (formwork), it is possible to prevent the sponge mold from floating. This eliminates the need to hire specialized contractors and leads to a reduction in unexpected labor costs due to chipping work after pouring, making it economical. Furthermore, since rafters are not required, it is characterized by a reduction in building material costs, a reduction in industrial waste, and a significant reduction in time, cost, and labor costs.
