Embodiment 1
[0022] Such as figure 1 As shown, the anti-falling waterproof device for long-span bridge girder ends provided by this embodiment 1 includes a water stop 2 and a support plate 3 arranged between the left and right girder ends 1, and the The two ends of the waterstop 2 are respectively connected to the beam ends 1 on both sides. The support plate 3 is fixed to the beam end 1 on the left side and both of them enclose a storage space with an open top. The support plate 3 is located in the waterstop 2, and its top constitutes a sliding part that slides in contact with the waterstop 2. The waterstop 2 extends into the storage space, and the waterstop 2 is hooked on the part extending into the storage space. The counterweight 4 is used to keep the waterstop 2 between the sliding part and the right beam end 1 in a stretched state, and also includes a cover plate 5 covering the top of the accommodation space.
[0023] Among them, the waterstop 2 between the sliding part and the right...

The invention discloses an anti-falling waterproof device for long-span bridge girder ends, which belongs to the technical field of bridge girder end waterproofing. By arranging support plates, it is enclosed with one side of the girder end to form a storage space, and the water stop One end of the belt can be slidably extended into the storage space, and is hooked with the heavy object in the storage space, so that the waterstop outside the storage space is always in a straight state, preventing it from being under the action of its own weight. , falling down to form a sunken area that is easy to accumulate water and dust, thereby effectively improving the service life of the entire waterproof device; at the same time, the present invention is also equipped with a cover plate on the top of the storage space to avoid Waterstops accumulate water and dust.
Description
technical field [0001] The invention relates to the technical field of bridge girder end waterproofing, in particular to an anti-drop waterproof device for long-span bridge girder end. Background technique [0002] With the continuous development of bridge structures, beam end telescopic devices have gradually entered the era of standardization. In the comb-tooth plate type telescopic device, the installation method of the beam end waterproof device is mainly to arrange a waterproof rubber skin under the tooth plate to achieve the purpose of waterproof and dustproof. However, due to the natural hanging state of the rubber, if the installation does not meet the design requirements, the rubber will fall under the action of its own weight to form a sunken area where water and dust accumulate, which will affect the service life of the waterproof device and also affect the maintenance access at the beam end. setting. Contents of the invention [0003] In summary, the technica...
