Abstract

The invention provides a fireproof door with a protective titanium alloy plate. The door comprises the external protective titanium alloy plate, a fireproof coating arranged on the outer surface of the titanium alloy plate in a coating manner and a concrete door blank wrapped in the protective titanium alloy plate. The concrete door blank comprises concrete and a round steel pipe in the concrete. Iron-based materials are adopted in the steel pipe so that the requirement for the bearing strength can be effectively met, and the steel pipe is good in corrosion resistance when making contact with the concrete. According to the fireproof door with the protective titanium alloy plate, the concrete is made of multiple mixings, and the compressive strength is achieved

Description

technical field [0001] The invention relates to a fireproof door with a protective titanium alloy plate, which belongs to the field of door industry manufacturing. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. Analyzing the mechanical characteristics of fire doors, it can be found that when the fire doors are subjected to impact loads, 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: steel beams are 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 d...
