Embodiment 1

[0025] Corrugated steel plate composite structure bridge deck system, such as figure 1 , 2 , 3, 6, including a corrugated steel plate 1, the corrugated steel plate 1 is provided with a reinforcement skeleton 2 and a stud 4, and the reinforcement skeleton 2 and the stud 4 are poured into the concrete. The corrugated steel plate is also used as a formwork, and studs and triangular truss steel bars are welded on the top surface of the corrugated steel plate to increase the structural strength of the composite deck system. The corrugated steel plate is not only used as a stress-bearing member of the bottom plate, but also as a formwork, and has the advantages of low maintenance cost in the later period, less safety hazards in the use of the bridge, convenient construction, and good overall economy. When used as a stressed member of the bottom plate, it improves the connection strength between the corrugated steel bottom plate and concrete and has good shear resistance. At the sam...

Abstract

The invention relates to bridges in civil engineering, and discloses a corrugated sheet steel composite structure bridge deck system. The corrugated sheet steel composite structure bridge deck system comprises corrugated sheet steel (1). A rebar framework (2) and toggle pins (4) are arranged on the corrugated sheet steel (1) and poured into concrete. The corrugated sheet steel serves as not only a bottom plate stress component but also a formwork in use and has the advantages of being low in maintenance cost in the later period, small in the number of potential safety hazards in use of a bridge, fast and convenient to construct, good in overall economical efficiency and the like, meanwhile wave troughs of the corrugated sheet steel play a role of stiffening ribs, so good diffusion of bridge deck loads is facilitated.

Description

technical field [0001] The invention relates to a bridge in civil engineering, in particular to a corrugated steel plate composite structure bridge deck system. Background technique [0002] Existing bridge decks all adopt reinforced concrete structures. The bottom of the bridge deck is shaped by supporting plates or formwork, and then reinforced concrete is poured. After the concrete is dry, the supporting plates or formwork are removed, leaving the bottom surface of the poured concrete. The concrete bridge bottom, after long-term use, the concrete is prone to fall off, which poses a threat to pedestrians or vehicles under the bridge. Contents of the invention [0003] Aiming at the concrete structure used on the bottom surface of the bridge in the prior art, the concrete is easy to fall off after long-term use and poses a threat to people or objects under the bridge. The maintenance cost is low, there are few safety hazards in the use of the bridge, the construction is ...
