Description

Technical Field

[0002] Currently, the main structural systems of railway passenger station canopies include steel structure canopies, cast-in-place concrete structure canopies, prefabricated monolithic concrete structure canopies, and fully prefabricated concrete canopies. Among them, fully prefabricated concrete structure canopies are gradually increasing in proportion due to their high construction efficiency. However, the existing methods for constructing expansion joints in canopy roofs have the following problems: (1) When the roof panel of the canopy is displaced due to temperature deformation, the waterproof layer on the cross joint return water board is easily damaged by pulling, resulting in the failure of the waterproof function; (2) The waterproof protective layer of the steel plate is easy to fall off, which poses a threat to the safety of the existing line; (3) The problem of backflow from the bottom of the beam to the column at the expansion joint has not been effectively solved.

[0003] Therefore, how to solve the waterproofing problem of the prefabricated concrete canopy roof structure has become a technical challenge that urgently needs to be overcome by those skilled in the art. Utility Model Content

This patent uses concrete covers independently anchored to the vertical rail beams to cover the cross-joints, completely separating the waterproof structure from the roof panels that may shift, thus avoiding damage to the waterproof layer due to temperature deformation. The concrete covers replace easily detachable steel plates, eliminating the safety threat to the downstream lines. This patent also uses a system of drip lines, water-blocking lines, and water-guiding lines to form a multi-layered waterproof system that combines isolation, obstruction, and guidance, effectively organizing rainwater paths and solving the technical problem of rainwater flowing back into the columns from the bottom of the beams.

[0005] This utility model is achieved through the following technical solution: A prefabricated concrete canopy waterproof roof structure includes vertical rail beams, longitudinal rail beams, edge beams, and roof panels. The vertical rail beams are fixedly assembled on piers along the vertical rail direction.

[0010] According to the above technical solution, preferably, when the edge beam is a composite edge beam including an upper return beam and a lower return beam, and the height of the roof water return plate at the cross joint is flush with the edge beam, the concrete cap extends horizontally outward from the end near the edge beam to form a cantilevered horizontal plate, the drip line is set at the bottom of the cantilevered horizontal plate, and the water-blocking line is set on the top surface of the edge beam.

The concrete cap replaces the easily detachable steel plate, eliminating the safety threat to the downline. (2) This patent forms a multi-layered waterproof system that combines isolation, obstruction and guidance through the drip line, water blocking line and water guiding line set by the system. It can effectively organize the rainwater path and effectively solve the technical problem of rainwater flowing back into the column from the bottom of the beam.
