Bridge expansion joint device with multiple water stop structures

Abstract

The invention discloses a bridge expansion joint device with multiple water stop structures. The bridge expansion joint device comprises a first anchor plate and a second anchor plate, wherein the first anchor plate and the second anchor plate are located on the two sides of an expansion joint. First F-type steel is arranged on the first anchor plate, second F-type steel is arranged on the second anchor plate, first F-type adhesive tape and second F-type adhesive tape are arranged in a groove of the first F-type steel and a groove of the second F-type steel respectively, the first anchor plate and the second anchor plate are welded with a first anchor bar and a second anchor bar respectively, a cover plate supporting block and third F-type steel are arranged on the upper portion of the second anchor plate, and third F-type adhesive tape is arranged on the third F-type steel. A cover plate installing plate is arranged on the top of the first anchor plate, a waterproof cover plate is installed on an installing cover plate through a bolt connecting assembly, a rubber pad is arranged between the installing cover plate and the waterproof cover plate, a pressed plate is arranged on the waterproof cover plate, and the cover plate installing plate and a cover plate supporting plate are respectively of a step type. The bridge expansion joint device with the multiple water stop structures has the advantages of being simple in structure, convenient to construct, good in waterproof effect, and capable of avoiding leakage or straight drainage towards the outside of a bridge in the using process.

Description

technical field [0001] The invention relates to the field of bridge engineering construction, in particular to a bridge expansion joint device with multiple water-stop structures. Background technique [0002] The water-stop structure of the existing bridge expansion joints mainly includes the water-stop structure of special-shaped steel bridge expansion joints with a "V"-shaped structure and the water-stop structure of comb-tooth plate bridge expansion joints. Among them, the waterstop of the special-shaped steel bridge expansion joint is a "V"-shaped structure, and the two sides are respectively embedded in the installation groove of the special-shaped steel, and the water is directly drained on both sides of the bridge or extended to the outside of the bridge. If it is tilted upward, it will not have drainage. Function, rainwater accumulated in the waterstop is prone to leakage or freezing; and in the process of use, all kinds of garbage is easy to fall into the structure...

Problems solved by technology

Among them, the waterstop of the special-shaped steel bridge expansion joint is a "V"-shaped structure, and the two sides are respectively embedded in the installation groove of the special-shaped steel, and the water is directly drained on both sides of the bridge or extended to the outside of the bridge. If it is tilted upward, it will not have drainage. Function, rainwater accumulated in the waterstop is prone to leakage or freezing; and in the process of use, all kinds of garbage is easy to fall into the structure, and after being rolled by vehicles, it will accumulate too much in the "V" shaped waterstop It is not easy to clean, and can cause the telescopic device to lose its telescopic function, and the "V" shaped waterstop will also be damaged and leak due to extrusion, losing its waterstop function

In addition, the waterstop structure of comb-tooth plate bridge expansion joints is generally installed on the lower part of the comb-tooth plate, or directly auxiliary on the lower part of the comb-tooth plate, fixed by the mounting bolts of the comb-tooth plate, or fixed on the expansion joint by an independent anchor structure. After the waterstop is used for a certain period of time, the rainwater will leak out through the joint between it and the beam body; and the waterstop will drain directly on both sides of the bridge or extend to the outside of the bridge. The tilting leads to poor drainage function, and rainwater accumulates in the waterstop, which is prone to leakage or freezing

[0003] It can be seen that the above two different waterstop structures cannot achieve ideal and effective waterstopping, and the drainage function is not good enough to meet the complete water tightness in the existing urban viaducts. Requirements for in-line rows outside the bridge
