[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments only are part of the embodiments of the utility model, not all the embodiments.
[0020] Embodiment 1: refer to Figures 1-3A kind of expansion joint waterproof structure, including mounting frame 1, mounting frame 1 is fixedly connected to the upper end of two buildings 2, expansion joint is provided between two buildings 2, the bottom end of mounting frame 1 is fixedly connected with connecting plate 3, the bottom end of connecting plate 3 is fixedly connected with telescopic sealing element 4, telescopic sealing element 4 is located in expansion joint, the bottom end of both sides of mounting frame 1 is connected with elastic sealing plate 5, the bottom end of each elastic sealing plate 5 is contacted with the upper end of building 2, and elastic sealing plate 5 is anticorrosive rubber sealing plate.
[0021] Working process:
[0022] When waterproofing expansion joint, mounting frame 1 drives connecting plate 3 to move, connecting plate 3 drives telescopic sealing element 4 to move, so that telescopic sealing element 4 moves to expansion joint, mounting frame 1 continues to move downwards, when the bottom end of mounting frame 1 is contacted with the upper end of building 2, building 2 supports mounting frame 1, mounting frame 1 is installed on the upper end of building 2 by fixed bolt, mounting frame 1 connects telescopic sealing element 4 by connecting plate 3, so that telescopic sealing element 4 is located in expansion joint, two buildings 2 extrude telescopic sealing element 4, and telescopic sealing element 4 is tightly attached to the inner wall of expansion joint after being pressed, so as to seal and waterproof expansion joint, two elastic sealing plates 5 seal both sides of mounting frame 1, so as to improve the waterproof effect of expansion joint.
[0023] Example 2: in example 1, when mounting frame 1 installs and fixes telescopic sealing element 4, water cannot be effectively drained, referring to Figure 2 , as another preferred embodiment of the utility model, and the difference from example 1 is that mounting frame 1 includes baffle 11, baffle 11 is sprayed with anticorrosive layer on the upper end, the bottom end of baffle 11 is fixedly connected with mounting plate 12 on both sides, two mounting plates 12 are fixedly connected to different buildings 2, the upper end of baffle 11 is fixedly connected with side plate 13 on both sides, water falls on the upper end of baffle 11, two side plates 13 shield the side edge of baffle 11, baffle 11 cooperates with side plate 13 to guide water, which is convenient for draining rainwater.
