Problems solved by technology

The main disadvantage is that when the load acts locally, the FRP bridge deck will be bent laterally, and at the same time be punched or squeezed; when the non-aligned load is applied, there will be torque on the section, and the feasibility of the processing technology is poor. Simple construction and insufficient applicability
[0006] 3. At present, the existing FRP composite bridge deck, because the size of a single bridge deck is too large, the prefabricated components are not easy to install and construct, so it is mainly cast-in-place structure, the construction period is long and the construction quality is difficult to guarantee

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] Prefabricated assembled FRP-reinforcement-concrete composite bridge deck, including, including prefabricated components of FRP-concrete composite panel with reserved channels ( figure 1 ) and transverse prestressed steel bars 8 and anchors 10. The FRP-concrete composite panel prefabricated component with reserved channels includes a semi-closed FRP groove 5, the two side plates of the FRP groove 5 are inverted L-shaped, and the upper edge of the inverted L-shaped side plate 1 is flush with the upper edge of the concrete 2, forming The three-sided FRP groove wraps the concrete structure. There is a T-shaped rib 4 in the middle of the FRP groove. The T-shaped rib 4 is connected to the upper surface of the FRP groove 5 bottom plate. The height is slightly lower than the inverted L-shaped side plate. The transverse prestressing tendon channel 6 is reserved in the r...

Abstract

The invention discloses a prefabricated assembly FRP-reinforcing steel-bar-concrete combined bridge deck and a construction method. The prefabricated assembly FRP-reinforcing steel-bar-concrete combined bridge deck comprises a semiclosed FRP groove and concrete inside the FRP groove, wherein the bottom surface and two side surfaces of the concrete are wrapped by the FRP groove to form the combined panel, a transverse through reinforcing steel bar reserved tunnel is formed in a transverse setting position of the combined panel, a transverse prestress reinforcing steel bar is arranged in the reinforcing steel bar reserved tunnel to connect a plurality of FRP-concrete combined panel prefabricated components to form an integral bridge panel structure in a needed size. The construction method comprises the steps: firstly producing the semiclosed FRP groove; arranging an FRP rib and an embedded corrugated pipe, and fixing the FRP rib and the embedded corrugated pipe; pouring concrete; splicing a plurality of prefabricated FRP-concrete combined deck components into a whole by utilizing the prestress after the strength of the concrete reaches the requirement. The factorization prefabrication and on-situ assembling of the FRP combined bridge deck are realized, the structure is simple, and the construction is convenient.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prefabricated assembled FRP-rebar-concrete composite bridge deck and a construction method. Background technique [0002] Corrosion damage of infrastructure caused by corrosion of steel bars and its impact on the economy have become prominent problems in the world today. Fiber reinforced polymer / plastic (FRP) is a new type of high-performance material formed by mixing fiber material and matrix material in a certain proportion and compounding through a certain process. It has the advantages of high strength, light weight, corrosion resistance, and fatigue resistance. , is a potential material to replace steel bars and prestressed steel bars in civil engineering structures, and can well solve the corrosion problem of ordinary steel bars and prestressed steel bars. [0003] At present, the research on the application of new FRP materials in civil engineering at home and...
