Description

[Detailed description of the invention] This invention relates to an assembly lid for a container.

It is already practiced to assemble large containers such as tanks from a large number of unit plates. Various types of unit plates are known, but the typical one is a right-angled rectangular plate whose four circumferences are all bent to the same side to provide a joint edge, and the whole It is shaped like a shallow box. With unit plates of this type, containers of various sizes can be assembled by using unit plates of the same shape and size and simply increasing or decreasing the number of unit plates. Therefore, this type of unit plate was extremely convenient as a unit plate for assembling containers.

The unit plate described above was used not only for the container body but also for assembling the lid. In this case, the joining edge was directed downward to prevent rainwater etc. from accumulating on the lid. However, in order to assemble a lid with the joint edges facing downward from the above-mentioned unit plates, first align the unit plates vertically and horizontally on the same plane with the joint edges facing upward, and then After connecting the edges with bolt-like connections, the resulting large slab must be turned upside down, with the joined edges facing down. However, turning such a large plate upside down is not only dangerous, especially when the wind is blowing, but also poses a risk of damaging the plate. Additionally, when configuring the lid with the joining edge facing downward, when it became necessary to tighten the bolts, scaffolding had to be assembled on the underside of the lid, which required extremely complicated work. . This invention was made to improve the above-mentioned drawbacks.

In other words, this idea bends the parts along two opposite sides of a square plate upward, makes one bent piece an upwardly protruding edge, and bends the tip of the other bent piece further downward to form a chevron shape. A projecting edge, the top of the chevron-shaped projecting edge is higher than the upper end of the upwardly projecting edge, and the corner of the chevron-shaped projecting edge and the corner of the upward projecting edge on one diagonal are cut out, and the unit plate is a plurality of unit plates. unit plates are arranged along the inclined surface, both protruding edges are aligned in the inclined direction, and the notch of the chevron-shaped protruding edge is positioned above the slope, and below the chevron-shaped protruding edge of the horizontally adjacent unit plate. Insert the upper protruding edge, overlap the lower end of the unit plate located on the upper side of the slope with the upper end of the unit plate located on the lower side, and align the notches of the chevron-shaped protruding edge and the upper protruding edge of the diagonally adjacent unit plates. It is an assembly lid for a container that is attached together.
