Abstract

The invention relates to a self-compacting concrete aluminum alloy edge-sealing formwork for a ballastless track. The self-compacting concrete aluminum alloy edge-sealing formwork for the ballastless track comprises two end molds, four standard side molds, two adjusting side blocks, four corner formworks, and four inserting boards, which are symmetrically assembled into the quadrilateral self-compacting edge-sealing formwork, wherein the end mold comprises a panel and upper and lower frame plates, a reinforcing rib is arranged in the middle part of the panel to form a groove shape, and the end mold is integrally molded by extrusion once through an aluminum profile extrusion device; the standard side molds and the adjusting side molds are made of square tube aluminum profiles, and are molded by extrusion once through the extrusion equipment, the corner formworks and the inserting boards are made of arc-shaped aluminum profiles, and are molded by extrusion once through extrusion equipment. The self-compacting concrete aluminum alloy edge-sealing formwork for the ballastless track provided by the invention solves the problems of slow turnover of the formwork, fewer use times, easy deformation, easy rusting, formwork swelling and mortar leakage of self-compacting concrete, poor exhaust effect, uneasy installation, great waste of human resources and the like under construction.

Description

technical field [0001] The invention relates to a ballastless track self-compacting concrete aluminum alloy edge-sealing template. 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, ...
