Side frame for large-scale box

Abstract

The invention relates to a side wall used in a large-scale case, comprising a plurality of unframed lateral plates which are mutually spliced and a splice structure for connecting the splice ends of two adjacent unframed lateral plates; the splice structure consists of an inner connecting piece which is clamped at both sides of the splice ends of two adjacent unframed lateral plates and positioned in the case, an outer connecting piece which is positioned at the outside of the case and a rivet used for connecting the inner connecting piece, the outer connecting piece and the splice ends of the unframed lateral plates, and the cross section of the overlap section of the inner connecting piece and the splice end of the unframed lateral plate is corrugated. The side wall used in a large-scale case in the invention adopts a corrugated inner connecting piece to replace the original inner connecting piece with a convex wave shape, thus the strength and rigidity of the connecting structure both meet the requirements of the case, steps projected from the inner side of the side wall can be eliminated, mutual collision and damage between cargoes and the steps at the side wall can be avoided, and the loading space of the case can be enlarged; moreover, as the overlap section of the inner and outer connecting pieces and the splice ends of two adjacent unframed lateral plates adopts inosculated corrugation for matching, the shearing stress of the rivet is reduced and the transverse connecting strength and connecting reliability of the side wall can be improved.

Description

technical field [0001] The present invention relates to a large box structure for loading goods, and more particularly relates to a side wall for a large box. Background technique [0002] Large boxes are widely used in the storage and transportation of goods, such as container boxes, van semi-trailer compartments, van compartments, etc. The side wall structure of large boxes needs to meet the strength requirements for storing and transporting goods, so higher requirements are put forward for the side wall structure. [0003] For example, the side wall of a traditional van-type semi-trailer body is composed of a skeleton structure plus an inner and outer skin (steel plate or aluminum plate) to form a side plate, and the side plates are riveted with each other to form a side wall. This structural feature of the side wall makes it thicker Large, heavy weight, difficult to maintain, and the width of the box is limited, so the side wall of this skeleton structure has gradually ...

[0005] 1. In order to make the frameless side plate connection structure meet the strength and rigidity requirements of the car body, the cross-section of the inner connector 11 of the side wall of the existing car body adopts a wave-shaped structure in which the middle part protrudes into the car body. In this way, the car body There are protruding steps on the inner surface of the side wall, which makes it easy to rub or even jam between the goods and the steps of the side wall during loading and unloading, which is easy to cause damage to the side wall structure and the goods;
