Antiskid device of movable formwork in heavy wind environment

The invention discloses an antiskid device of a movable formwork in the heavy wind environment. The antiskid device comprises a hook plate, a pull rod and a pin shaft. The hook plate is composed of abent plate and a side plate. The bent plate sleeves a flange of a box girder. The pin shaft is used for connecting the pull rod with the hook plate and connecting the pull rod with the movable formwork. Embedded angle iron is arranged at the contact position of the bent plate of the hook plate and the upper right corner of the flange of the box girder. A rubber cushion is arranged at the contact position of the inner side of the bottom of the bent plate of the hook plate and the bottom of the flange of the box girder. Four reinforcing ribs are welded between the bent plate and the side plate.The movable formwork can be temporarily fixed to the upper side of the box girder, the transverse collapsing of the movable formwork on the upper side of the box girder under the influences of typhoons, monsoons and other heav
