Assembly type steel plate combined beam bridge based on reinforced concrete combined bridge deck slab and construction method of assembly type steel plate combined beam bridge

Abstract

The invention discloses an assembly type steel plate combined beam bridge based on a reinforced concrete combined bridge deck slab and a construction method of assembly type steel plate combined beam bridge. The steel plate combined beam bridge comprises a main beam supporting structure composed of multiple main steel beams, and multiple reinforced concrete combined bridge deck slab sections installed on the main beam supporting structure from front to back, wherein the multiple main steel beams are I-beam main beams distributed in the longitudinal bridge direction. The reinforced concrete combined bridge deck slab sections comprise multiple reinforced concrete combined bridge deck slab units distributed from left to right. Longitudinal cast-in-place concrete structures are evenly distributed over the main steel beams. The construction method includes the steps of firstly, bridge lower portion supporting structure construction, secondly, main steel beam erection construction, thirdly, reinforced concrete combined bridge deck slab section installation, fourthly, longitudinal connecting reinforcing steel bar penetration, and fifthly, longitudinal cast-in-place concrete structure pouring construction. The assembly type steel plate combined beam bridge is reasonable in design, easy and convenient to construct, good in use effect, excellent in mechanical performance, high in installing and detaching construction speed, short in construction period and capable of effectively solving the problem that the main beam interval is too large.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an assembled steel plate composite girder bridge based on a steel-concrete composite bridge deck and a construction method thereof. Background technique [0002] Steel plate composite girder bridges are composed of steel girders, concrete bridge decks and connecting systems. For bridge decks with a large width, it is usually connected in the form of longitudinal wet joints. At the wet joints, it is necessary to build formwork, connect reserved steel bars, and pour wet joint concrete. This construction method has complicated procedures and requires on-site operations. The amount is large, and it is not convenient for secondary replacement of the bridge deck. [0003] The rapid assembly construction of steel plate composite girder bridges is a construction method that develops relatively rapidly at home and abroad. It is widely used in rapid construction of...
