A DROP DOWN SUPPORT OF FLAT EURO FORM FALL PREVENTION

摘要

A drop-down support apparatus for preventing a euro-form from falling down on the bottom is provided to prevent a euro-form from falling down directly on the bottom when dismantling a euro-form, to improve workability and work efficiency by preventing impact sound, to have the effect of noise reduction and to exclude the public grievance of the surrounding areas, and to separate a drop-down support apparatus simply from a timbering in case of dismantlement. A drop-down support apparatus for preventing a euro-form from falling down on the bottom comprises a fixed pipe(2) formed on the upper part of a connection plate(5) to be projected in the longitudinal direction, a hanger piece operator installed to the inside of the fixed pipe and positioning a movable pipe to the top and the bottom selectively, and a lever operator(6) installed to the lower part of the fixed pipe and operating the hanger piece operator selectively. The lever operator comprises a rotary shaft penetrating two ends of the lower part of the fixed pipe, a rotary hanger piece(6c) provided to two outer circumferential surfaces of the fixed pipe to rotate together with the rotary shaft, a connection piece provided to two ends or one side of the rotary hanger piece, and a lever(6a) connected to the outside of the connection piece to operate with hands. The hanger piece operator comprises an operating bar connected to the rotary shaft, formed long in the longitudinal direction and provided with a long hole on the upper part, a hinge shaft inserted to the long hole and provided to the top of the fixed pipe, and a pair of hanger pieces(7-6) installed to the hinge shaft and provided with a support at the top and a hanging projection at the bottom.
