Abstract

The invention discloses a post-poured hidden coping construction method for converting simply supported beam into continuous beam. Plate girders are precast in a plant, are then connected with precast plate girders at two sides thereof via cast-in-situ copings so as to convert the precast plate girders into continuous beams, wherein the method of combining supports is adopted to carry out construction, in the method, a temporary support for installing the precast plate girders and a formwork support for installing the post-poured hidden copings are combined to be one, thus obtaining excellent effect.

Description

technical field

[0001] The invention relates to a construction method for municipal bridge construction, in particular to a construction method for a post-cast concealed cover beam in which simply supported beams are converted into continuous beams. Background technique

[0002] With the development of a large number of urban municipal construction projects, the construction quality and progress requirements of municipal bridge construction have also gradually increased. The traditional simply supported slab girder only adopts continuous bridge deck, and its stress structure needs to be improved. At present, in bridge construction, people have adopted a simple-supported variable-continuous bridge construction technology, that is, prefabricated prestressed concrete hollow slab girders in the factory, and erected temporary brackets on site to install them in place, and the slab girders on both sides are prefabricated through on-site pouring. The stress-reinforced concrete cov...
