About This Product
■Summary
1. Labor saving on site
Σbase is a solution to the labor shortage at construction sites due to work style reforms and the aging of skilled craftsmen. Compared to conventional cast-in-place foundations, the man-hours needed to construct a foundation for a single-family house can be reduced by more than 30%, and the construction period can also be cut in half.
2. High strength and high precision
Obtained evaluation from Japan Architectural Center Foundation. In terms of durability and construction accuracy, it has performance equivalent to or better than general residential foundations.
3. I-Construction
Σbase is currently the only solution that can save labor, encourage the advancement of women, and introduce systems in housing foundation construction.
■Features
1. Differences from general housing foundations
A typical housing foundation is called a "cast-in-place foundation," which is a construction method in which concrete is poured into formwork assembled at the construction site. On the other hand, precast concrete foundation Σbase is a construction method in which concrete blocks (precast concrete) manufactured in advance at a factory are assembled at the construction site like Lego blocks to create a high-quality foundation for a home.
2. Sliding rail joint
The simple structure of simply inserting the male mold into the female mold of the metal fittings and injecting grout streamlines installation work. Dimensional accuracy can be adjusted in millimeter increments, and the finished form is rated as more accurate than cast-in-place foundations.
3. Wave cotter
A cotter is a structural part that is necessary to withstand the shear force applied when connecting blocks. Normal cotters are box-shaped, but compared to that, the wave-shaped cotter is an invention of our company that has approximately 1.6 times the shear strength.
