The invention provides a connecting structure of precast concrete bridge deck plates. The connecting structure comprises the first precast bridge deck plate and the second precast bridge deck plate and further comprises a plurality of press type steel bars. The multiple press type steel bars are anchored on the side portion of the second precast bridge deck plate, and reserved holes correspondingto the press type steel bars are formed in the side portion of the first precast bridge deck plate. The press type steel bars are pressed into the reserved holes and then are connected with hole wallsof the reserved holes in a fastening mode after the shape is recovered. Compared with the prior art, the connecting structure and a connecting method of the precast concrete bridge deck plates have the beneficial effects that a clamping structure is formed by arranging the reserved holes and the press type steel bars, so that the connection between the first precast bridge deck plate and the second precast bridge deck plate is more fastened, the integrity of the bridge deck plates is improved, and meanwhile, stress at seam positions is relieved.
Description
technical field [0001] The invention relates to the technical field of roads and bridges, in particular to a connection structure and connection method of prefabricated concrete bridge decks. Background technique [0002] In the existing prefabricated bridges, the conventional connection method of prefabricated bridge decks is: the upper and lower steel bars protruding from the two prefabricated bridge decks are arranged alternately, and the two prefabricated bridge decks overlap each other in the longitudinal position. The overlapping steel bars are welded together. Then concrete is poured at the joint of the two prefabricated bridge decks, and the connection is completed after vibration and curing. However, there are certain defects and deficiencies in this connection method. First, it is difficult to arrange the longitudinal reinforcement of the two prefabricated bridge decks in a staggered manner. Moreover, there will be a large gap between the staggered steel bars, whi...
