The invention relates to a lightweight compartment bottom plate with high corrosion resistance. The lightweight compartment bottom plate comprises a bottom plate assembly, a plurality of cross beams arranged at the lower part of the bottom plate assembly and playing a supporting role, a plurality of reinforcing blocks arranged at the joints of the cross beams and a girder of a vehicle body, and edge sealing plates arranged on the two sides of the bottom plate assembly in the length direction respectively. The lightweight compartment bottom plate is characterized in that the bottom plate assembly is formed by connecting a plurality of bent bottom plates in parallel; the bent bottom plates, the cross beams, the reinforcing blocks and the edge sealing plates are all formed by bending plate materials. According to the lightweight compartment bottom plate with the high corrosion resistance, the whole lightweight compartment bottom plate is manufactured through plate bending, splicing and assembly welding, under the condition that the compressive strength meets the use requirement, the flatness, the light weight, the corrosion resistance and the applicability of the bottom plate are greatly improved, according to the actual use condition of a vehicle, the optimal bending height and width are selected within a certain range, the manufacturing and processing procedures are simpler, the welding deformation is smaller, and the performance is better.

    本发明涉及一种具有较强防腐性能的轻量化车厢底板,包括:底板组件、以及设置在底板组件下部起支撑作用的若干横梁、以及在横梁与车身大梁连接处设置的若干加强块、以及在底板组件长度方向的两侧分别设置的封边板,其特征在于,所述底板组件由若干折弯底板平行连接组成;所述的折弯底板、横梁、加强块、封边板均由板料折弯而成。本发明的具有较强防腐性能的轻量化车厢底板,通过整体采用板材折弯、拼接、组焊制作,在抗压强度满足使用情况下,底板的平整度、轻量化、防腐性能、适用性得到大幅增强,还能够根据车辆使用的实际情况,在一定范围内选择最佳折弯高度和宽度,并且制作加工工序更加简单、焊接变形更小,性能更好。
