Description

Technical Field

[0001] The utility model relates to the field of track plate steel cages, in particular to a track plate steel cage fixing mechanism. Background Art

[0002] The track slab steel cage is a very important part of the railway track structure. It is mainly used to fix and support the track slab to ensure the stability and bearing capacity of the track. The steel cage is usually composed of steel bars and concrete, and can resist various forces generated when the train is running, including longitudinal tension and lateral shear force. During the construction process, the steel cage will be precisely placed in the predetermined position, and then concrete will be poured to make it firmly combined with the track slab. The track slab can withstand the weight of the train and the vibration during operation, ensuring the safe and smooth running of the train.

[0003] The existing track slab steel cage structure generally weaves and welds steel bars into a cage-like structure on the plate body, which is then placed in a pre-built concrete frame and fixed. Concrete is then poured, and the concrete fills the gaps in the steel cage and is tightly combined with the steel to form a solid whole. During the installation process, the track slab steel cage generally connects the grounding terminal on the steel cage to the underground grounding system through a wire to ensure that the generated static electricity or fault current can be introduced into the earth in time, thereby protecting the safety of equipment and personnel. However, the installation process of this structure is relatively cumbersome and is easily affected by aging, corrosion or mechanical damage, which may cause the performance of the wire to deteriorate or break, posing certain safety hazards.
