basic information
The FA box is a construction method that combines precast components divided into three parts with cast-in-place concrete to create large-section boxes. By adopting a separated structure for the top slab and side walls, it has become possible to standardly accommodate sites with slopes. ○ The product's composition is a combination of slabs, which results in low manufacturing costs. ○ Traditionally, the connection of precast components often used PC steel materials, but the FA box integrates them using loop joints with cast-in-place concrete, making construction easier. ○ In addition to water-stopping gaskets at the joints between components, waterproofing materials are applied, and water-stopping sheets are used to enhance the water-stopping effect.
