Construction Method of Tram Slab Girder

Abstract

The invention provides a construction method of a tramcar plate beam. The construction method includes the steps that firstly, the size of notches formed in a plate beam body is determined; secondly, twisted steel is bound, a formwork is fixed, space of the notches is reserved, and rail structure connecting steel bars need to be embedded in grooving positions; thirdly, concrete is poured to the twisted steel, the formwork and the rail structure connecting steel bars, prestressed bundles of bars are tensioned, the plate beam body is formed, and the two pairs of notches are formed in the plate beam body; fourthly, the twisted steel is bound into the notches, concrete is poured, and rail structures are laid, wherein the rail structures comprise rail bearing tables and rails arranged on the rail bearing tables; fifthly, a waterproof layer and a protective layer are sequentially laid on the plate beam body, and after the waterproof layer and the protective layer are laid, the top faces of the rails and the top face of the plate beam body are flush with the bridge floor of an existing highway bridge. The invention further discloses the tramcar plate beam.

Description

technical field [0001] The invention relates to the field of bridge structures, in particular to a tramway plate girder and a construction method thereof. Background technique [0002] Tram is a light-duty small-group rail transit vehicle driven by electricity and running on the track. Tram is a kind of public transportation, also known as streetcar or tram for short, which is a kind of light rail. Since trams are driven by electricity, the vehicles do not emit exhaust gas, so they are a pollution-free and environmentally friendly means of transportation. In recent years, tram, as a new type of urban rail transit, has developed rapidly. [0003] Tram line laying is characterized by laying on the bottom surface, and laying along the middle of the existing road. In this way, it will often encounter the situation that the line passes through the middle of the existing road bridge, and the middle of the existing road bridge needs to be installed. Parts were reinforced or demo...

Problems solved by technology

For the existing small-span highway bridges, because the height of the small-span simply supported plate girder structure of the highway bridge is small, the conventional tram bridge is to lay the track structure on the top of the plate girder, so that even the tram bridge can To achieve the same structural height as the highway bridge, it is also difficult to achieve the level of the track elevation and the existing highway bridge elevation, so the mixed right of way on the bridge cannot be realized, and the beauty of the bridge structure is also affected
