Lightweight compartment bottom plate with high corrosion resistance

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of trucks, and in particular relates to a lightweight carriage floor with strong anti-corrosion performance. Background technique [0002] The weight of the traditional truck compartment is heavy, which reduces the cargo weight of the truck, and the main weight of the compartment is on the floor. The traditional cargo floor process generally uses thicker square pipes and channel steel to form a frame by welding, welding pads, straight beams, and then laying iron plates on the frame surface, adding welding reinforcements and other supporting parts. , heavy weight, cumbersome workmanship, and limitations in overall height design. [0003] On the other hand, the bottom plate is flatly laid on the frame formed by the combination of square tubes, relying on enough contact area with the square tubes to meet the requirements of strength and flatness. Therefore, the square tubes need to be densely arranged, which m...

AI Technical Summary

Problems solved by technology

[0005] 1. No matter how the rust is removed, the inner side of the square tube cannot be rusted;

[0006] 2. The interlayer between structural parts cannot achieve anti-corrosion coating

[0007] In addition, the wall thickness of the square pipe and channel steel is much thicker than that of the bottom plate laid on the upper part. Materials with a large difference in thickness will affect the welding performance and cause large deformation after welding.
