Problems solved by technology
[0004] 1. When the staff installed the device, due to the uneven ground, they could not support the structure used by the device well, thus affecting the effect of the device;
[0005] 2. The overall stability of the device is general and the protection effect is poor, which affects the service life of the device. For this reason, we propose the aluminum material design of the ballastless expansion joint device to solve the existing problems

The invention discloses an aluminum material design for a ballastless expansion joint device, which includes a concrete layer, a foundation and a base. A support frame is fixedly installed on the top, a protective cover is slidably installed on the top of the casing through a limit rod, a long bar is fixedly installed on the top of the fixed seat, and a connection is slidably installed on the other side of the long bar through a connecting groove. block, the other side of the connection block is fixedly installed with an adjustment platform, the surface of the other side of the limit bolt is rotatably installed with a connecting sleeve, the other side of the connecting sleeve is fixedly installed with a steel bar, and the There is a waterproof belt through the sealing head. The present invention is provided with a series of structures so that the device can be adjusted according to the actual installation situation in the process of use, and has the advantages of strong overall stability of the device and good protection effect, and optimizes the use process.
Description
technical field [0001] The invention relates to the technical field of ballastless expansion, in particular to the design of an aluminum material for a ballastless expansion joint device. Background technique [0002] Ballastless track (Ballastless track) refers to the track structure that uses concrete, asphalt mixture and other integral foundations to replace the loose-grained gravel track bed. It is also called ballastless track. It is an advanced track technology in the world today. Ballastless track and ballasted track Compared with the ballastless track, it avoids ballast splashing, has good smoothness, good stability, long service life, good durability, less maintenance work, and the train can run at a speed of more than 350 kilometers per hour. Expansion joints refer to preventing construction Due to climate temperature changes (thermal expansion, cold contraction), the structure will crack or be damaged, and a structural joint set at an appropriate part along the di...
