Description
Technical Field
The invention relates to a fire-resistant end wall of a rail transit vehicle structure and a rail transit vehicle, and belongs to the field of rail vehicle cab structures.
Background
The cab and the passenger compartment of the rail transit vehicle are arranged in a separated mode, when unstable factors such as artificial disorder or spontaneous combustion occur in the passenger compartment, flames or other dangerous factors can be effectively prevented from spreading to the cab through the rear end wall of the cab, and therefore the effect of protecting safety of vehicle operation equipment and drivers is achieved.
According to EN 45545-3:2013 railway applications-railway vehicle fire protection part 3: the fire resistance requirement of the fire barrier is specified to carry out a fire test of a fire partition wall, the fire resistance integrity requires that a cotton pad on the back fire surface is not allowed to be ignited, flame lasting for 10s or more than 10s does not appear on the back fire surface, when a crack penetrating into the test furnace appears on the back fire surface of the sample, a probe with the diameter of 6mm penetrates through the crack to enter the furnace, the moving distance along the length direction of the crack is not more than 150mm, and a probe with the diameter of 25mm cannot pass through the crack to enter the furnace; the fire resistance and heat insulation require that the average temperature rise of the back fire surface is not more than 140 ℃; the highest temperature rise of any point of the back fire surface of the end wall is not more than 180 ℃. The surface layer of the rear end wall of the cab of the existing rail transit vehicle mainly adopts a steel plate or fireproof coating scheme to meet the requirement on the fire resistance of the structure, and the whole fire-receiving surface is made of fireproof coating to increase the weight of the end wall; in addition, the construction of the fireproof coating has more or less quality problems of sagging, cracking, pinholes and the like, and the adhesive force of the coating also influences the quality of the whole coating system. Along with the reduction of the physicochemical property and the fireproof performance of the coating in different degrees, the fire resistance limit of the coating is obviously reduced. Accelerated aging tests show that some fireproof coatings have the phenomena of early foaming, powdering and even shedding. The fire insulation time of the fireproof coating is the inspection result of 1-2 months after the coating is coated, and the occurrence of fire is probably after the service of the coating for several years. If the coating has poor aging resistance, the due fire-proof capability of the coating is weakened or even lost, and if a fire occurs, the later case is not imaginable.
