AI Technical Summary

Technical Problem

Existing formwork devices for constructing staircases are cumbersome, expensive, and require separate installation of piles and steps, leading to inefficiencies and increased material usage.

Method used

A formwork device comprising first and second pillar formworks with integrated lower and front walls that allow simultaneous construction of pillars and steps, reducing the need for piles and minimizing material bulk, while using lightweight materials and reinforcement to enhance robustness.

Benefits of technology

The device enables efficient, cost-effective, and robust construction of staircases with reduced concrete usage, as pillars and steps are built simultaneously, resulting in a stronger structure that is easier to transport and assemble.
