Arc formwork invert trestle that radially overturns

The utility model discloses an arc formwork invert trestle that radially overturns, including main bridge and fixed mounting bracket, the radial tilting mechanism of arc formwork is used for radiallyoverturning to two sections articulated formula arc formwork of corresponding side, and the radial tilting mechanism of arc formwork is including activity cantilever, first lift cylinder, second liftcylinder, swing hydro -cylinder, first upset hydro -cylinder and second upset hydro -cylinder, two sections articulated formula arc formwork are held by an arc formwork's the outside and form with the2nd arc formwork's medial extremity is articulated. Adopt two sections articulated formula arc formwork to combine each self -correspondingly radially to be overturn with radial tilting mechanism ofarc formwork that the activity cantilever constitutes by a plurality of hydro -cylinders, furthest vacates the space of inverted arch arc formwork and rebar installation, the ligature scope of operation, makes inverted arch arc
