PURPOSE: A mold for installing a machine device is provided to be repeatedly used although the diameter of a concrete structure is variously transformed by being easily expanded lengthwise and breadthwise. CONSTITUTION: A mold for installing a machine device comprises a plurality of corner members (10), a plurality of extension plates (20), fixing units (30,40), and a height control member. The corner member comprises a first plate unit (11) and a second plate unit (12) and includes a first connection protrusion (13) and a first connection groove (14) on both ends. The extension plate vertically and horizontally expands the mold by being included between the corner members and includes a second connection protrusion (21) and a second connection hole (22) on both ends. The fixing unit fixes the extension plate to the corner member. The height control member controls the height of the concrete injected into the inner space of the mold. |
