Description

Technical Field

[0001] This utility model belongs to the field of bridge expansion joint water guiding technology, specifically a railway bridge expansion joint water guiding device. Background Technology

[0002] To accommodate deformation caused by stress and temperature, gaps must be left between bridge beams to allow for expansion and contraction. Installing expansion joints at these gaps prevents water leakage, corrosion, and damage to the beams (piers), supports, and inspection equipment.

[0003] The expansion joints widely used in railway bridges generally meet daily usage requirements, but they share a common weakness: difficulty in inspection and maintenance. The waterproof rubber strips in these joints have a short lifespan and are prone to detachment, damage, and aging, leading to leaks and failing to achieve the intended protective effect. Leaks can damage both the expansion joint and the bridge structure. In such cases, it is necessary to dismantle and replace track components, which is difficult and disrupts normal train operation.

[0004] Therefore, it is particularly important to develop a stretching device that is not easily damaged, easy to install, easy to replace, easy to maintain, easy to guide, and has a long service life. Utility Model Content

[0013] A T-groove is provided on one side of the steel section A along its length. The stainless steel water guide plate is fixed between the other side of the steel section A and the steel section B. The anchoring component is a T-bolt. One end of the T-head of the T-bolt slides in the T-groove and is fixed to the steel reinforcement embedded in the bridge body after sliding into place.

[0014] The dust cover is connected to the steel section A by connecting bolts. The dust cover has a waist-shaped hole, through which the connecting bolt passes and can slide.

[0015] One end of the connecting bolt is connected to section A, and the other end of the connecting bolt is fitted with a nut, and a cotter pin is provided at the end of the other end of the connecting bolt.

[0016] The advantages and positive effects of this utility model are as follows:

[0017] 1. The steel profile of this utility model is made by pressing steel profile A and steel profile B together, which makes installation convenient, quick and safe; the stainless steel water guide plate greatly increases the service life of the telescopic water guide device and solves the problems of aging and weathering that easily occur in rubber strips during use.
