Corrugated plate steel mold integrated composite structure bridge deck system and construction technology thereof

Abstract

The invention relates to a corrugated sheet steel bridge deck system, and discloses a corrugated plate steel mold integrated composite structure bridge deck system and a construction technology thereof. The bridge deck system comprises corrugated sheet steel (1), a bent rebar (5), a straight rebar (6) and concrete (2). The bent rebar (5) is connected with the straight rebar (6) which is connected with the corrugated sheet steel (1), and the concrete (2) is poured to the upper portion of the corrugated sheet steel (1). The construction technology comprises the steps of assembling the corrugated sheet steel (1) on scene, welding the rebar or toggle pins, pouring the concrete (2) and welding steel stiffening ribs (3) on the lower side of the corrugated sheet steel (1). The corrugated sheet steel is adopted to serve as not only a bridge deck steel concrete combination structural part but also a bridge deck concrete formwork, meanwhile wave troughs of the corrugated sheet steel form multiple rib beams, so the system has good resistance to bending, especially bent force transferring rebars are configured on the corrugated sheet steel, and the phenomenon of poor combination of the bridge deck system is eliminated.

Description

technical field [0001] The invention relates to a corrugated steel plate bridge deck system, in particular to a corrugated plate steel mold integrated structure bridge deck system and its construction technology. Background technique [0002] At present, the bridge deck system is an important structure that bears the live load of the bridge deck and distributes the bridge deck load through the force transmission mechanism. Most of the traditional structures are pure reinforced concrete structures or flat-plate steel-concrete composite structures. The durability of the bridge deck system is directly related to Until the service life of the bridge, the deck system of pure reinforced concrete structure is not only thick, but also has poor force transmission performance of the bridge deck, and the falling of concrete debris also poses a safety hazard to descending vehicles and people. The deck system of the flat-plate steel-concrete composite structure is not strong in bending r...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the shortcomings of the common bridge deck system in the prior art that are not only thick and heavy, but also have poor force transmission performance of the bridge deck, and the falling of concrete debris also poses safety hazards to the descending vehicles and people. As a steel-concrete composite structure of the bridge deck, it is also used as a bridge deck concrete formwork. At the same time, the wave troughs of the corrugated steel plates form multiple rib beams, which have good bending resistance. The poor combination of surface systems has been better solved. The bridge deck system and its construction technology of the corrugated plate steel formwork integrated structure
