Description

Technical Field

[0001] The invention relates to an insulation device and method between an end door of a subway platform door and an equipment wall. Background Art

[0002] In recent years, subway platform doors have become essential equipment for newly built subways in China. The insulation of subway platform doors is a critical issue for the safety of the platform door system and, consequently, for the personal safety of passengers. Platform door insulation aims to insulate the entire platform door structure from the civil engineering. To achieve this, effective insulation between the platform door structure and the civil engineering must be first addressed. As part of the platform door structure, the platform door end doors must not only be insulated from the upper roof beam and the lower platform civil engineering, but also from the lateral equipment walls. However, due to significant on-site construction errors in the end door and equipment walls, the distance between the end door structure and the equipment walls cannot be guaranteed. Furthermore, the installation schedule of the platform door and equipment wall is determined by the progress of each specialized project, making it difficult to control the order of construction. This results in uneven gaps between existing subway platform door end doors and the equipment walls. If the gap is too small, insulation between the end door and the equipment wall cannot be guaranteed; if the gap is too large, subsequent gap sealing becomes a construction issue on-site, leading to frequent disputes between the platform door and decoration professionals. Furthermore, the uneven insulation gaps of the end doors affect the appearance of the platform door end doors. Summary of the Invention
