Detailed Description
The utility model will be further described with reference to specific examples and figures.
As shown in fig. 1 and 2, a prefabricated key groove plate bridge deck structure comprises a main beam 1 and a prefabricated key groove plate 2. The prefabricated key groove plate 2 is made of steel plates, and is transported to a construction site for paving after being processed and produced in a factory. The prefabricated key way plate 2 is provided with a depressed portion 21 and a protruding portion 22 along its length direction. The prefabricated key groove plates 2 are arranged in a plurality, and the prefabricated key groove plates 2 are continuously paved on the main beam 1 along the length direction of the main beam 1 and are fixed with the main beam 1 through bolts. The sunken parts 21 and the raised parts 22 on the plurality of the connected prefabricated key groove plates 2 are sequentially and circularly arranged at intervals to form a wave-shaped bending structure, and non-shrinkage steel fiber concrete is poured on the plurality of the connected prefabricated key groove plates 2 to form the concrete bridge deck 3.
