A separate box-type parking guide signboard structure

Abstract

The disclosure of the present invention relates to a separated box-type parking guide signboard structure, which relates to the field of signboards, including the secondary lining of tunnels. The separated box-type parking guide signboard structure includes: an aluminum alloy frame assembly, and the aluminum alloy frame assembly includes : aluminum alloy frame, the aluminum alloy frame is arranged on the surface of the secondary lining of the tunnel; aluminum alloy bottom plate, the aluminum alloy bottom plate is connected with the lower part of the aluminum alloy frame; at least one reinforced steel plate, at least one reinforced steel plate is arranged on Inside the aluminum alloy frame. The structure of the disclosed technical solution provides a parking guide signboard structure of a railway tunnel emergency rescue station with a stable and firm structure and good visibility.

Description

technical field [0001] The invention discloses and relates to the field of signs, in particular to a split box type parking guide sign structure. Background technique [0002] As part of the railway tunnel emergency rescue station system, the parking guide sign of the railway tunnel emergency rescue station plays an extremely important role in the safe parking of railway traffic, especially fire trains. Most of the existing parking guide signs are of the rectangular overall structure type with the text area size of 700mm × 2300mm and 700mm × 2680mm (width × height) specified in the "Railway Tunnel Disaster Prevention, Evacuation and Rescue Engineering Standards" (TB10020-2017). Although the sign board of this structure is easy to make, it is often installed in close contact with the inner surface of the lining when installing the curved wall lining surface of the railway tunnel, which causes the text area of ​​the sign board to be parallel to the center line of the line, and...

AI Technical Summary

Problems solved by technology

Although the signboard with this structure is easy to manufacture, it is often installed on the lining surface of the curved wall of the railway tunnel by being installed close to the inner surface of the lining, which causes the text area of ​​the signboard to be parallel to the center line of the line, and the visibility is poor. It is beneficial for the train driver to quickly extract the information on the sign board and make a correct judgment

[0003] In order to improve the visibility of the signboard, the signboard will also be rotated at a certain angle and installed on the side wall of the tunnel, but this rectangular overall structure signboard occupies a large clearance in the tunnel, which is not conducive to the induction of piston wind and fatigue for a long time Under the action, it is easy to be twisted, deformed, damaged and dropped, which will affect driving safety
