Abstract (en)

[origin: EP4112815A1] The present invention discloses a double-span movable formwork of lower bearing type and a construction method. The formwork includes a main girder, a main bridging beam, a bracket, a propelling flat wagon, a cross beam, an outer shuttering, a front hanging beam and a rear hanging beam. Two main girders are provided, the main girders are connected through a plurality of pairs of cross beams, and the cross beams are in group in pairs with bottom ends thereof connected by bolts. The main bridging beam is fixedly connected to either end of the main girder, three pairs of brackets are provided at bottoms of the main girder and of the main bridging beam at either end of the main girder respectively, for supporting the main girder and the main bridging beam, each pair of brackets are connected through a connecting plate, and the propelling flat wagon is slidably connected to the top of the respective bracket. According to the present invention, through the arrangement of a close jointing apparatus, after the two parts of the outer shuttering are closed by the hydraulic device on the propelling flat wagon, the two cross beams of the same pair can be simultaneously fixed, and the top of the close jointing apparatus is embedded into the joint of the outer shuttering, so that a gap at the joint cannot be communicated up and down, preventing continuous leakage and improving safety.
