Description

Technical Field

[0001] The utility model relates to the technical field of assembled beam bridges, in particular to a fully assembled steel plate beam bridge structure. Background Art

[0002] Conventional bridges generally use reinforced concrete or prestressed concrete structures, which need to be cast on site or prefabricated and then erected in one piece. The construction period of the cast-on-site construction method is long, which is not conducive to the requirements of rapid road traffic. In the method of erecting in one piece, the beam section is prefabricated in the prefabrication plant, and the prefabricated beam section is transported to the construction site for erection. The construction progress is fast and the construction period is short, which can meet the requirements of rapid road traffic. However, for large-span bridges, the transportation difficulty of the beam section will increase due to the large length of the beam, and stability problems are prone to occur during the erection process. Since the composite structure bridge gives full play to the good tensile properties of steel and the good compressive properties of concrete, it has the advantages of light weight, high bearing capacity, simple structure, convenient construction, and low noise of traffic blocking. It is more and more widely used in highways and municipal engineering.

[0003] The existing bridge deck body still has some shortcomings. The process is relatively complicated and the construction time is very long, which greatly prolongs the construction period. During installation, holes need to be drilled on the main beam, which reduces its load-bearing capacity. Utility Model Content
