Container floor unit, underframe and method for producing container and underframe

Abstract

A container floor unit, a chassis, and a method for producing the container and the chassis, the container floor unit comprises: a base plate with a flat upper surface and at least two bottom beams protruding at the bottom of the base plate, the base plate and the bottom The beam is integrally formed. The container chassis includes a chassis main body, and the chassis main body is composed of at least one container floor unit. When the chassis main body is composed of more than two container floor units, the container floor units are arranged in order in the longitudinal direction. In a row, the bottom beams of each container floor unit face the lateral direction, and the adjacent container floor units are connected together by the bottom beams. The integrated container floor unit greatly simplifies the structure of the container floor, revolutionizes the complicated and complicated container production process in the past, greatly improves the efficiency of container production, and greatly reduces the cost of container manufacturing.

Description

technical field [0001] The invention relates to the field of containers, in particular to an integrated prefabricated underframe structure and a production method of the underframe and the container. Background technique [0002] At present, the main structure of a standard container is mainly surrounded by five parts: the bottom frame, the front end, the rear end, the side wall, and the roof. The chassis mainly includes two bottom side beams arranged longitudinally, a plurality of bottom beams vertically fixed between the two bottom side beams and arranged at intervals, and a floor laid on the bottom beams. [0003] Common dry container floors are mainly divided into two types, one is wood flooring and the other is steel flooring. [0004] When producing the underframe of the wooden floor structure, the bottom side beam and the bottom beam are generally welded into a steel structure first, then the wooden floor is laid on the steel structure, and then the wooden floor is s...

AI Technical Summary

Problems solved by technology

This structure is currently the most widely used container underframe structure, but this structure has the following disadvantages: (1) The number of bottom beams is large, the amount of welding with the bottom side beams is large, and it is difficult to realize automatic welding, and the labor cost is high. serious pollution

(2) It takes a lot of manpower and material resources to lay the floor, and it also needs to use a large number of floor nails to connect with the bottom beam. After drilling, arranging nails, locking nails and cleaning, the process is complicated and the labor cost is high

(3) The wooden floor and the bottom beam are connected at points. The floor and the bottom beam cannot be an integral force-bearing part. The moment of inertia and the bending section coefficient of the bottom beam are relatively low. There are problems such as jumping nails, slipping wires, delamination, cracking or even breaking

[0005] When producing the underframe of the steel floor structure, it is also necessary to weld the bottom side beam and the bottom beam to form a steel structure first, and then lay the steel floor. Although the steel floor underframe cancels the drilling, nail row, locking nail and Cleaning and other processes also avoid the phenomenon of floor delamination, breakage, jumping nails, slipping wires, etc., but there are also cumbersome procedures for laying the floor, and additional processes such as welding, sanding, and painting are added. The sand after the sanding process It is also difficult to clean. At the same time, because the steel floor and the bottom beam are connected by flower welding, the stress is concentrated on the weld during use, which makes the weld easy to crack, and this kind of crack is generally difficult to find, which is likely to cause safety hazards
