Grassland Mobile Container House
The grassland mobile container house is a mobile temporary or long-term residential building unit transformed on the basis of containers. It is widely used in grassland areas for characteristic accommodations, temporary camps, construction site housing, and other scenarios.
Design and Structural Features
The grassland mobile container house is not simply using containers directly as houses. Instead, it undergoes secondary design and system integration from three dimensions: structural mechanics, material thermal engineering, and assembly processes. For example, to address the issue of insufficient floor stiffness caused by the large spacing between the longitudinal beams of the traditional container's bottom frame, C-shaped steel purlins are added between the bottom beams to evenly distribute the load to each main beam, enabling the container body to maintain structural stability even when stacked three layers high. At the same time, after shot blasting and rust removal, the container body surface is coated with protective paint, allowing the steel to maintain an effective service life of more than 15 years in the northwest's windy and sandy environment with large temperature differences.
Thermal Insulation Performance
The metal container body has a high thermal conductivity coefficient, and relying solely on panel insulation is difficult to cope with the severe cold in northern winters. For this reason, a three-layer structure is adopted. The outer layer is galvanized sheet to resist wind and sand erosion, the middle layer is filled with rock wool as the main insulation layer, and the inner layer uses PVC-coated steel plate to reduce thermal radiation. Some companies also add an elevated layer at the bottom of the container body to block the conduction of ground cold bridges. The improved solution adopts a broken-bridge lining structure, that is, filling hard polyurethane foam between the steel frame and the inner wall panel and adding rubber thermal insulation pads at the connection points of the keels, reducing the heat exchange efficiency between the inside and outside of the container by about 40%. In winter without heating, the indoor temperature can be 8 to 10 degrees Celsius higher than the outside.
Application Scenarios
In grassland areas, mobile container houses have various application forms. For example, the designer container hotel on the shore of Lake Buir lights up the grassland with bright colors, creating a unique contrast between the rigid steel and the soft lake water, which is deeply loved by young tourists. There are also tent camps and starry sky bubble houses in grassland scenic spots, and container houses can serve as supporting facilities to provide tourists with a variety of accommodation experiences. On construction sites, container construction site houses can be built in multiple layers and installed conveniently, serving as field construction housing, construction office dormitories, etc.
Environmental Protection Advantages
The core value of container houses lies in the full life-cycle recycling of their materials. Each standard 20-foot container consumes about 1.2 tons of steel. If a one-time poured concrete temporary house is used, the carbon emissions of concrete and steel bars required for the same area are 2.3 times that of a container house. Moreover, when the camp is relocated or the project is completed, the container house can be hoisted as a whole to a new site, with the disassembly and assembly loss rate controlled within 5%, greatly reducing the generation of construction waste.
