Embodiment 1

[0056] A truck compartment floor modular construction structure, the truck compartment floor module includes: a floor 1, a front beam 2, a rear beam 3 and a side panel 4; The two ends of 3 are connected, and the tops of the front beam 2, the rear beam 3 and the two frames 4 are respectively fixedly connected with the bottom edge of the floor 1.

[0057] The front end of the front beam 2 is evenly provided with a plurality of positioning bosses 5, the positioning boss 5 includes a cone 51 and a positioning pin 52 connected with the cone 51, one end of the positioning pin 52 is connected with the cone 51, and the positioning pin 52 is connected to the cone 51. The other end is connected with the front beam, and the diameter of the frustum 51 becomes larger gradually from the far beam end to the near beam end.

[0058] The front beam 2 is provided with a plurality of bolt connection holes 7 , and the bolt connection holes 7 and the positioning bosses 5 are alternately arranged on...

Embodiment 2

[0070] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0071] The upper surface of the floor 1 is a smooth surface or a patterned surface, the floor 1 is a hollow floor, and its hollow structure is a square through hole, and the opening direction of the square through hole is parallel to the short side of the floor 1; The lower part of the floor 1 is provided with reinforcing ribs 9, the reinforcing ribs 9 are bow-shaped, the height of the middle part is higher, and the height of both sides is lower, and the section of the reinforcing ribs 9 is an inverted T shape.

Embodiment 3

[0073] Embodiment 3 is basically the same as Embodiment 2, and its difference is:

[0074] The outside of the side plate 4 is provided with a hinge for fixing the side wall panel of the compartment.

Abstract

The invention discloses a modular construction and assembly method of a boxcar bottom plate. The boxcar bottom plate comprises a floor, a front cross beam, a rear cross beam and side plates. Wherein the two ends of the front cross beam are connected with the two ends of the rear cross beam through side plates respectively, and the tops of the front cross beam, the rear cross beam and the two frames are fixedly connected with the bottom edge of the floor respectively. According to the method, the to-be-produced boxcar bottom plate is formed by combining the pre-produced modules with different sizes, so that the serialization production of the boxcar bottom plates with different sizes is conveniently realized, the mounting process can be simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for modular construction and assembly of the bottom plate of a truck compartment, and is particularly applicable to the field of assembly accessories of trucks. Background technique [0002] A truck is a commercial vehicle designed and equipped mainly for carrying goods, also known as a truck, which refers to a car mainly used to transport goods, sometimes also refers to a car that can tow other vehicles, and belongs to the category of commercial vehicles. Trucks are roughly divided into four categories according to their compartments: box trucks, tank trucks, flatbed trucks, and slab trucks. [0003] The truck compartment is an important structure to ensure the transportation of goods. The structure and size of the truck compartment affect the stability and safety of cargo transportation. However, the load-bearing floor of the existing truck compartment usually needs to use metal materials to make longitudinal beams a...
