Problems solved by technology

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

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...

Abstract

The invention discloses an anti-falling type waterproof device for the beam end of a large-span bridge. The invention belongs to the technical field of bridge beam end waterproofing. A support plate is arranged to define an accommodating space with the beam end on one side, one end of the water stop belt can extend into the accommodating space in a sliding manner to be connected with the heavy object arranged in the containing space in a matched mode , so that the water stop belt located outside the containing space is always in a stretched state and is prevented from falling downwards to form a concave area where water and dust accumulate easily under the action of dead weight, and the service life of the whole waterproof device is effectively prolonged; meanwhile, a cover plate coveringthe top of the containing space is further arranged in a matched mode so that water and dust accumulation of the water stop belt in the containing space can be avoided.

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...
