Container bottom plate and container bottom plate unit made of novel composite material for container bottom plate

Abstract

The invention relates to a container bottom plate unit made of a novel composite material. The novel container bottom plate unit is made of the fiber strengthening polymer matrix composite material and comprises a panel and a plurality of webs, the bottom of the panel downwards extends to form the webs, the webs comprise two end webs located at two ends of the panel and a middle web located in the middle of the panel, and the heights of the two end webs are equal to or lower than the height of the middle web. Container bottom plate units can be in lap joint along transverse inner fasteners or / and are spliced with 'Omega'-shaped container steel center sills in a matched manner to form an total container bottom plate. The container bottom plate unit is made of the fiber strengthening polymer matrix composite material, a bottom plate unit structure and a splicing mode thereof, which correspond to the material, are adopted, and accordingly the container bottom plate unit has an excellent environmental protection performance, an excellent lightweight performance and an excellent installation performance.

Description

technical field [0001] The invention relates to a container bottom plate and a container bottom plate unit thereof, in particular to a container bottom plate unit made of fiber-reinforced polymer-based composite material and a container bottom plate spliced ​​by the container bottom plate unit. Background technique [0002] In the existing container structure, the bottom structure of the container is the main bearing part. The bottom structure of the container includes an underframe and a bottom plate laid on the underframe of the container. The underframe of the container includes two parallel and longitudinally arranged bottom side beams, several bottom cross beams arranged transversely between the two bottom side beams, and At least one mid-ground beam in the shape of "Ω" or in-line arranged longitudinally. [0003] The bottom structure of the container is the main load-bearing part of the container, so it puts forward higher requirements for the strength and good appear...

Problems solved by technology

[0006] 3. Installation features: Traditional wooden container floor units need to lay at least 12 floor panels in a 40-foot standard container. The installation process is to use manual or equipment to spread the floor units on the bottom frame of the box, and insert the front, rear, left, and right positions (manually) , drawing lines and drilling positioning, drilling, nailing, locking and other processes, the labor intensity is high and the efficiency is low

[0007] 4. Splicing method: The traditional container floor unit assembly method is generally to set a tenon on one side of the floor unit and "Ω"-shaped or in-line center beam or bottom side beam angle steel to be spliced ​​with each other through sealant. The method can effectively play a sealing role, but when two adjacent bottom plates are subjected to asynchronous force, a single bottom plate unit will be deformed or slightly displaced, and then form a squeeze on the adjacent bottom plate unit, resulting in Local damage or delamination at the contact position between two adjacent floor units

The traditional container bottom plate is often scrapped due to local damage at the assembly interface, which affects the service life of the bottom plate
