General Specification for fire protection for construction, GB55037-2022, implemented on 1/6/2023, 6.3.1: the elevator shaft should be independently arranged, and the inside of the elevator shaft should not be laid or penetrated by combustible gas or liquid pipelines of A, B and C types, wires or cables irrelevant to the operation of the elevator, and the like. The fire-resistant integrity of the elevator landing door should not be below 2.00h. In addition, according to national standard "building design fire Specification" GB50016-2014 (2018 edition) 6.2.9: the elevator shaft should be independently arranged, and combustible gas, first, second and third class liquid pipelines and cables, wires and the like irrelevant to the elevator should not be laid in the shaft. The walls of the hoistway should not be provided with other openings except for the elevator door, the security escape door and the ventilation holes. The codes require that the elevator hoistway be provided independently, allowing the design of the ventilation holes of the elevator hoistway.

According to national standard "building design fire protection Specification" GB50016-2014 (2018 edition) 3.2.1 and 5.1.2 are defined in primary, secondary and tertiary fire-resistant grade buildings, the fire-resistant limit of the elevator shaft wall should not be lower than 2.00h, 2.00h and 1.50h respectively, and the combustion performance should be incombustible. For underground construction and underground engineering, the fire resistance limit of the elevator shaft wall is not lower than 2.00h, and the combustion performance is incombustible.

According to the general Specification for fire protection of buildings 6.3.4: the electric lines and various pipelines pass through the fire wall, the fire-proof partition wall, the shaft wall, the deformation joint of the building and the pore of the floor slab to take fire-proof plugging measures.

In the conventional fireproof measures that the opening on the fireproof partition wall can be closed when firing, firstly, a fireproof door and a fireproof window are adopted, if the fireproof door and the fireproof window are adopted, the wall of the well is only 200mm wide, and in the normal use state, the fireproof door and the fireproof window are required to be opened and protrude out of the inner wall of the well, so that the use of the elevator well is affected. The practical use requirements cannot be met. Secondly, the fire damper is plugged, and according to the working principle of the fire damper, the fire damper is usually arranged on a pipeline of a ventilation and air conditioning system with fire-fighting requirements; a valve used on pipeline features that the air pipe passes through the wall and no joint is allowed in the wall. The fire damper is mounted no more than 200mm from the wall surface. The elevator is also installed by protruding the wall surface, and can not meet the use requirement of an elevator shaft. Thirdly, installing the fireproof roller shutter. Above way is because the structure setting needs installation space big, needs protrusion elevator shaft setting, in order to dodge the setting of elevator car and other structures, needs the size of enlarging the elevator shaft, increases the user shared area, has increased manufacturing cost.
