Constructional column fixing formwork used in winter

The invention discloses a constructional column fixing template used in winter. The constructional column fixing template comprises a first combined permanent magnet template, a second combined permanent magnet template and a temperature sensor, the first combined type permanent magnet formwork and the second combined type permanent magnet formwork are arranged on the two sides of the masonry walls correspondingly, and a constructional column pouring space is formed by the first combined type permanent magnet formwork, the second combined type permanent magnet formwork and the two masonry walls. Iron core coils, namely a first iron core coil and a second iron core coil, are respectively arranged in the two combined permanent magnet templates; the first iron core coil, the first parallel circuit, the mobile distribution box, the transformer, the main switch, the ampere meter, the second parallel circuit and the second iron core coil are connected in sequence; the temperature sensor collects the temperature of
