Prefabricated plate bolt connection system of fabricated composite beam bridge and construction method of prefabricated plate bolt connection system

Abstract

The invention relates to the field of bridge engineering, in particular to an assembly type composite beam bridge prefabricated slab bolt connection system and a construction method thereof.The assembly type composite beam bridge prefabricated slab bolt connection system comprises a plurality of prefabricated bridge deck slabs with holes and bolt fasteners arranged between the adjacent slabs, and steel beams are connected with the prefabricated bridge deck slabs with the holes through bolt shear keys; the prefabricated bridge deck slabs with the holes are connected through the bolt fasteners, the two ends of each bolt fastener are located in the corresponding horizontal preformed hole, the epoxy resin layers are laid in gaps between the slabs, and water leakage is prevented. The device is applied to beam bridge construction and has the advantages of simple structure, convenience in assembly, high implementation speed and the like.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to an assembled composite girder bridge prefabricated slab bolt connection system and a construction method thereof. Background technique [0002] With the further advancement of bridge industrialization, the construction method has gradually changed from the traditional on-site pouring of all components to factory prefabrication of some or most of the components, and then transported to the site for installation; compared with traditional construction methods, the industrial prefabrication method first requires What is solved is the connection between the various prefabricated components. At present, the bridge deck of the bridge mainly adopts the cast-in-place construction method. Due to the large operating area of ​​the bridge deck, a large number of dry shrinkage cracks and temperature cracks are prone to appear during the concrete pouring of the bridge deck, which seriously af...

Problems solved by technology

At present, the bridge deck of the bridge mainly adopts the cast-in-place construction method. Due to the large operating area of ​​the bridge deck, a large number of dry shrinkage cracks and temperature cracks are prone to appear during the concrete pouring of the bridge deck, which seriously affects the durability of the bridge, and the partial damage of the bridge deck in the later stage is difficult to replace.
