Problems solved by technology

Moreover, when the pre-loaded static load method is used for construction, the ballast is added to the structure, and measures must be taken to control the ballast value, and the bridge deck needs to be laid intermittently, which makes the construction process extremely inconvenient and the workload is also very large

Abstract

The invention discloses an assembly type steel-concrete combined continuous beam bridge deck formed by exerting prestress to a concrete bridge deck in a hogging moment region. The deck comprises a hogging moment region concrete segmental plate, a hogging moment region concrete end plate and a sagging moment region segmental plate. The manufacturing method comprises the following steps of erecting of shuttering, pouring and curing; the deck is applied to the construction of a steel-concrete combined continuous beam bridge. Prestress is exerted to the inner part of the concrete bridge deck of the hogging moment region, but a tendon beam is not used, so that material consumption is reduced, the crack resistance and the bending resistance bearing capacity in the hogging moment region are effectively improved, and the condition that prestress beams rust is avoided; during construction of the steel-concrete combined continuous beam bridge, an assembled type prefabricated prestressed concrete deck is adopted, so that the factory degree is high, the quality of structural members is guaranteed, and the durability of a concrete bridge deck is improved. The assembly type steel-concrete combined continuous beam bridge deck disclosed by the invention is simple in method, convenient to construct, and high in quality, the construction period is greatly shortened, and the comprehensive economic benefits are improved.

Description

technical field [0001] The present invention relates to a steel-concrete composite beam, in particular to a steel-concrete composite continuous girder bridge deck and its manufacturing method and application, in particular to a method of applying prestress in the concrete bridge deck in the negative moment zone Prefabricated steel-concrete composite continuous girder bridge deck and its manufacturing method and application. Background technique [0002] Steel-concrete composite beam is a new type of structure developed on the basis of steel structure and concrete structure. It mainly resists the lifting and relative slippage at the interface between the steel beam and the concrete bridge deck by setting shear connectors (bolts, channel steel, bending bars, etc.), making it a whole and common Work. Compared with reinforced concrete beams, steel-concrete composite beams can reduce the weight of the structure, reduce the earthquake action, reduce the size of the section, incr...
