Abstract

Provided is a sealing door of a basement. The sealing door comprises concrete sealing door blank and a titanium alloy sheet externally wrapped by the concrete sealing door blank. The concrete sealing door blank comprises circular steel pipes and concrete wrapping the circular steel pipes. The outer surface of the titanium alloy sheet is coated with an anticorrosion coating. The sealing door of the basement has following beneficial effects: mixed material of various kinds is adopted by concrete material and reaches the compressive strength of 7d:31MPA; 28d:52MPa; and the anticorrosion coating ensures weather fastness of the outside of the titanium alloy sheet.

Description

technical field [0001] The invention relates to a basement airtight door, which belongs to the field of door manufacturing. Background technique [0002] A hermetic door is a door that can meet the requirements of airtightness, stability and isolation within a certain period of time. It is located in a channel with a certain degree of airtightness such as a vertical shaft. Analyzing the mechanical characteristics of the airtight door, it can be found that when the airtight door is subjected to an impact load, the door body will bear a large out-of-plane bending moment, and it is unreasonable to use steel beam concrete columns to resist this bending moment: the steel beam is due to Its material characteristics have good bending performance, and it is easy to buckle under compression. With the occurrence of various safety incidents, the requirements of fire protection engineering for door safety and sound insulation are also constantly increasing. The traditional design has ...
