Abstract

The invention discloses a basement sealing door. The sealing door comprises a concrete sealing door blank and a titanium alloy board by which the concrete sealing door blank is wrapped. The concrete sealing door blank comprises circular steel pipes and concrete by which the circular steel pipes are wrapped. The outer surface of the titanium alloy board is coated with a corrosion resistant coating. As the steel pipes are made of iron-based materials, the requirement for the load bearing strength can be effectively guaranteed, and as the steel pipes are in contact with the concrete, the corrosion resistance is good; the concrete of the basement sealing door is made of various mixed materials, and the compressive strength reaches 31 MPa under the 7-d condition and 52 MPa under the 28-d condition.

Description

technical field [0001] The invention relates to a basement airtight door, which belongs to the field of door manufacturing. Background technique [0002] Hermetic door refers to 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...
