Introduce the body structure of the dining car
The car body is an all-steel welded thin-walled cylindrical structure without a center beam, the side wall panels are flat plates, and the floor is corrugated steel plates. High-strength weathering steel is used for plates and pressed parts with a thickness of 6 mm or less; ordinary carbon steel is used for those with a thickness of more than 6 mm. Stainless steel is used for corrosion-prone parts such as the flat roof of the roof air conditioner and the kitchen floor.
There are rain eaves on both sides of the roof and the rain eaves on the door. The side doors are equipped with straight-up pedals and the three-position corners are set on the roof. Fixed escalator. There are roof parking spaces within 2 m on both sides of the corbel, and running zone card sockets on both sides of the wall, and side light sockets and sequence card sockets near the four-position side doors. In order to ensure that the steel structure is not severely corroded within 15 years, the steel surface is pretreated.
After thorough drying, apply 604 heavy-duty anti-corrosion paint to the inner surface of the steel structure and the outside of the underframe, the thickness of which is greater than or equal to 200 μm; Greater than or equal to 60μm. The topcoat is made of high-grade polyurethane paint, the roof is painted three times, the thickness is greater than or equal to 90 μm, and the side walls are painted twice.
The car body heat insulation material adopts tightly packed ultra-fine glass wool board, and aluminum foil is added to the inside of the wall and roof heat insulation material. All the heat insulation materials are installed firmly and tightly. To ensure a good thermal insulation effect. The wooden frame of the whole vehicle is treated with anti-corrosion and fire prevention. The wooden frame and the steel frame are firmly connected by bolts, and the wooden frame is connected to the wall to enhance the sound insulation and vibration reduction effect. The partition wall behind the kitchen stove and the boiler is equipped with heat insulation and fire protection devices, and the stove chimney and boiler chimney are equipped with fire protection devices on the top of the car to ensure safety.
