Benefits of technology

This new technology solves problems by replacing complicated steps involved during casting-on-site concrete structures while maintaining their strength over time without requiring expensive specialized tools like bolts. It also simplifies the structure's manufacturing process compared to traditional methods that require multiple stages before it can be used for use on other projects due to its improved durability against corrosion caused by water ingression from cracks formed at joint interfaces when exposed to rainwater.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance and durability of large span structures made up entirely of reinforced cables (referred to hereinafter also called rebar). These structural components require connections between them during building stages for effective functioning. However current methods have limited success because they involve multiple steps involved before final placement, which makes these connections difficult and slow down overall production times. Therefore there needs an improved methodology to connect these parts together more efficiently without requiring excessive manual effort.

Abstract

The invention discloses a fully-assembled prefabricated concrete girder bridge superstructure and further provides a construction method of the fully-assembled prefabricated concrete girder bridge superstructure. The fully-assembled prefabricated concrete girder bridge superstructure comprises prefabricated concrete box girder single bodies, prefabricated concrete guardrails and a bridge deck paving layer. The prefabricated concrete box girder single bodies comprise prefabricated concrete box girder bodies; flange plates are arranged on the two sides of top plates of the prefabricated concretebox girder bodies; transverse splicing rigid prefabricated pieces are pre-embedded in the flange plates; the prefabricated concrete box girder single bodies further comprise transverse partition plates, and transverse partition plate splicing rigid prefabricated pieces are pre-embedded in the transverse partition plates; longitudinal splicing rigid prefabricated pieces are pre-embedded in the twoends of the prefabricated concrete box girder bodies; the adjacent prefabricated concrete box girder single bodies are transversely and longitudinally spliced; and the prefabricated concrete guardrails are connected with the prefabricated concrete box girder single bodies, and guardrail locking nuts are assembled on guardrail connecting bolts. Through the structure, cast-in-place concrete and negative moment prestressed ribs of the prefabricated concrete girder bridge superstructure in the connecting construction process can be omitted, and all components of the superstructure are fully assembled.
