ELEVATOR PIT STRUCTURE

摘要

An elevator pit supporting structure is provided to decrease construction cost and a construction period by reducing depth of a floor installation part more than thickness of a pit supporting bottom part. An elevator pit supporting structure includes a pit lower end(100), a bottom installation unit(200), a pit supporting bottom part(300), and a pit supporting wall(400). The pit lower end includes an inner space surrounded with a side wall. The pit lower end is arranged on the bottom installation unit. The pit supporting wall extended from the pit supporting bottom part supports an outer circumference of an elevator moving space. A supporting reinforcing rod(S) is arranged inside the supporting bottom part vertically and horizontally.
