The contents of this application are incorporated herein by reference in their entirety.

The present invention relates to container assemblies. More particularly, the present invention relates to a container assembly for concrete formwork and/or the absence of a shoring or scaffolding system for supporting the formwork.

During the construction of buildings, formwork is used in concrete construction to provide a surface or mold into which wet concrete can be poured to form structures such as, for example, floor slabs and beams. In the case of floor slabs, it is commonly used in the formwork to be installed on the previous floor to form the floor of a multi-story building to be formed sequentially and the sequentially higher floor.

Generally, post or scaffold systems are used to support elevated forms, including formwork that can be removed from a concrete slab when concrete is laid, or formwork that has been lost (ie not reusable). The reusable formwork may include an aluminum formwork pan secured to the top of the scaffold. Also, sheets or boards may be used on top of the framework.

The shorting scaffold system assembly process, and sequential formwork, require numerous essential elements (or parts) to be raised to the required heights. This is usually done using pallets.
