Container Stacked House
Container stacked houses are vertically stacked living spaces transformed from shipping containers, featuring modularity, flexibility, portability, and cost-effectiveness. They are widely used in engineering camps, commercial pop-ups, and temporary government and enterprise constructions. The following provides an introduction from aspects such as structure, installation, performance, and application cases:
Structural Aspect: Common structural types of container houses include welded integral boxes and bolt-connected assembled boxes. Welded boxes are formed by integral welding in factories, with a direct load path. The roof load is transferred through sidewall columns to the bottom sill, and then evenly distributed to the ground through the bottom sill, providing strong resistance to deformation and suitability for frequent lifting and relocation. Assembled boxes, on the other hand, use standard panels connected by bolts, with multiple connection nodes in the load path. The tightness of each node directly affects the overall stability.
Installation Aspect: Installation involves multiple technical steps. Ground preparation should provide a uniform load-bearing foundation for the container house. For long-term fixed use, a concrete strip foundation should be poured, while for short-term use, prefabricated concrete pads or steel plates can be used. During lifting and positioning, the contact state between the box and the foundation should be precisely controlled, using steel wire ropes with sufficient load-bearing capacity to ensure synchronous force application at all lifting points. After the box is positioned, check the fit between the bottom sill and the foundation pad, and use a level to detect horizontal errors.
Performance Aspect: Structural stability is a core safety indicator, with varying wind and earthquake resistance among different brands of products. For example, the product from Suzhou Zhongnan Steel Structure Co., Ltd. exhibits a maximum frame deformation of only 2mm under the action of a 12-level strong wind. In terms of thermal performance, metal containers have high thermal conductivity coefficients, so a three-layer structure is commonly used to improve insulation performance. Some enterprises also add an elevated layer at the bottom of the container to block cold bridge conduction from the ground.
Application Case Aspect: There are cases such as a family of four in a Jiangsu town using containers to build a rustic cottage on the original foundation; a Danish man transforming nine containers into a family residence; and a mountain hotel abroad composed of six containers.
