摘要： 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.

摘要： An installation method of a bent cap for mutually restraining adjacent pier studs in a prefabricated and assembled bridge is provided. A bent cap mold base is configured in a form of a bent cap, which includes fixedly arranging limiting steel rings at two ends of a rectangular frame and vertically arranging steel bar sleeves in the limiting steel rings, hoisting the cap bent mold base on top portions of adjacent two prefabricated pier studs, such that pier stud pre-embedded steel bars protruding from the top portions of the two prefabricated pier studs are correspondingly inserted into the steel bar sleeves at two ends of the bent cap mold base one by one, and limiting the adjacent two prefabricated pier studs in the bent cap mold base. Through the method provided by the disclosure, construction efficiency of bent cap installation may be significantly improved, and engineering quality may also be ensured.
