Lower side beam structure of side-opening container

Abstract

The invention discloses a lower side beam structure of a side-opening container. The lower side beam structure of the side-opening container aims at being simple in structure, convenient to manufacture and high in strength and rigidity. The lower side beam structure of the side-opening container comprises I-shaped steel which is formed by welding an upper wing plate, a lower wing plate and a web plate between the upper wing plate and the lower wing plate, wherein the cross section of the I-shaped steel is in an I shape. The lower side beam structure is characterized in that a strengthening plate parallel to the web plate is welded to the outer side end between the upper wing plate and the lower wing plate; the length and the height of the strengthening plate are the same with those of the web plate; and the upper wing plate, the lower wing plate, the web and the strengthening plate are flat steel. According to the lower side beam structure of the side-opening container, due to the fact that the strengthening plate parallel to the web is added on the bases of the original I-shaped steel, the modulus of a bending resistance section of the lower side beam is effectively increased, a whole lower side beam becomes a closed frame type structure, strength and rigidity of the lower side beam are improved, and the requirement for mechanical performance for the side-opening container lower side beam bearing heavy cargoes can be met.

Description

technical field [0001] The invention relates to a container, in particular to a lower side beam structure of a side-opening door container. Background technique [0002] Containers have become an international standard means of transport for multimodal transport. A common container includes a bottom plate and side plates on both sides of the bottom plate, a top plate fixed to the two side plates opposite to the bottom plate, an end plate at one end of the bottom plate and fixed to the two side plates and the top plate, and an end plate opposite to the end plate. Openable door panels are respectively fixed on the corner posts at the other end. A locking device fixed to the base plate and the door plate is arranged on the door plate. This kind of container is our common back door container. Since the size of the opening of the end door is limited by the width of the box, goods that need to be shipped with dimensions exceeding the width of the box cannot be loaded into the b...
