Abstract

The invention relates to a high-speed railway aluminium alloy track plate pressing device. The device comprises a tie down block, landing legs, side fixing plates, pressing pull rods and pushing screws; the device is characterized in that the tie down block and the landing legs are welded perpendicularly to form a shape of a door; the side fixing plates are arranged at the lower ends of the landing legs in parallel and connected with the landing legs through bolts; the pressing pull rods are connected with a track base plate and the tie down block and connected with reserved openings of the track base plate in a suspended mode through rebar; the pushing screws push an edge sealing formwork through the side fixing plates; the landing legs and the side fixing plates are made from aluminum alloy materials. Accordingly, it is guaranteed that ballastless track construction is conducted smoothly, the self-compacting concrete pouring quality is guaranteed, and the working efficiency is improved; construction installation and transportation are convenient, operation is easy, learning is fast, and the self-compacting concrete pouring quality and the fixed track plate space position are guaranteed; turnover is conducted many times, and the phenomena of track plate floating, the self-compacting concrete layer open joint and the like are avoided.

Description

technical field [0001] The invention relates to a pressing device for a high-speed iron aluminum alloy track plate. Background technique [0002] As an important structural component of the CRTSⅢ slab ballastless track structure, the self-compacting concrete layer plays a key role in linking the up and down and transmitting the longitudinal, transverse and vertical loads from the upper track structure. Its construction quality determines the CRTSⅢ slab ballastless track structure. success or failure. As the key material of this structural layer, self-compacting concrete cannot be vibrated because it needs to be poured after the fine adjustment of the track slab is completed. Therefore, the requirements for construction materials and ratio of self-compacting concrete layer are high, and the technical requirements for tooling and pouring technology are also quite strict. Self-compacting concrete is capable of flowing and self-compacting under its own gravity, and can be comp...
