In order to meet the requirements for accommodating flat stretchers, the dimensions of the car must be determined first. Through the comparison of stretchers of different specifications, the stretcher after reconstruction has the characteristics of being close to the human body and being portable, and it is most reasonable to use it as a stretcher to rescue critically injured persons. In the fire elevator car, a stretcher with a diagonally flattened modification is utilized to fully utilize the car space and reduce the car size as much as possible. According to the shape and dimensions of the stretcher, it can be seen that when the net size (width×depth) of the fire elevator cage is 1 600 mm×1 580 mm, the net entrance width of the car is 900 mm, and the elevator door is centered. The modified stretcher can be placed flat in the fire elevator car.

The provision of a fire-extinguishing elevator capable of accommodating flat stretchers is not only a fire-fighting high-rise building fire, but also a practical need for rapid rescue of critically wounded people. It is also in line with the fundamental purpose of "people-oriented, life-orientated" to ensure the safety of people's lives. Article 6.4.2 of the “Residential Design Code” stipulates that for buildings with more than 12 floors and more than 12 floors, each building shall have no less than two elevators, and an elevator that can accommodate stretchers shall be installed. The fire elevator car can meet the needs of accommodating flat stretchers. It not only can quickly rescue critically injured people in a state of fire in high-rise buildings, but also plays an important role in quickly rescuing critical patients. Therefore, the author proposes that in the revision of the current "High-rise Civil Building Design Fire Protection Code", the fire elevator car size, the size of the opening of the ladder door and the minimum size of the fire-fighting elevator's exclusive flat stretcher to make specific provisions, so that the fire elevators can accommodate flat The function of the stretcher is put into full play to play an important role in firefighting and rescue.
