Container House Piping Module

The piping modules of container houses are typically installed during the factory prefabrication stage, including water and electricity pipelines, bathroom equipment, etc. After being transported to the site, they are quickly connected to the main structure through standardized interfaces to form a complete living unit.

Prefabrication and Integration of Piping Modules

The piping system of container houses adopts a highly prefabricated design. The main structure, water and electricity pipelines, bathroom waterproofing, bathroom equipment (such as toilets and sinks), cabinets, etc., are all installed on the factory assembly line. For example, in a steel structure modular production line of a smart factory in Guangdong, through the collaborative operation of welding, assembly, and grinding robots, the house is disassembled into six components: the bottom, top, and four sides. These components are produced simultaneously on multiple sub-production lines and finally assembled into a complete container at the end of the production line, with the piping module integrated. This mode ensures the standardization of piping layout and construction accuracy, with manufacturing errors stably controlled within 1-2 millimeters.

On-site Connection of Piping Modules

After being transported to the project site, the piping modules are quickly connected to the main structure through standardized interfaces. For example, corner fittings serve as the only stacking force transmission points, bearing the force transmission between the upper and lower containers while integrating piping connection functions. For multi-story stacked container structures, the corner fittings and corner columns must be aligned and locked vertically to ensure vertical piping continuity; horizontal container connections are achieved through transverse打通 (transverse connection) designs to connect the piping systems of large spaces such as conference rooms and exhibition halls. In addition, modular houses adopt a parallel operation mode, with piping installation and structural assembly progressing simultaneously, significantly shortening the on-site construction period.

Technical Specifications for Piping Modules

According to the "Technical Specification for Modular Combined Houses", piping modules must meet the following requirements:

• Material and Durability: The container body steel adopts welding weathering steel (GB/T 4171), and non-container body components use Q235B/Q345B to ensure the stability of the piping supports; the enclosure filling prohibits the use of flammable core materials such as EPS. For crowded places, Class A rock wool/glass wool is used, with a fire resistance limit of ≥0.5 hours.
• Seismic Resistance and Leak Prevention: The piping layout must consider seismic fortification requirements (≤8 degrees). When large openings weaken the stiffness, a staggered and symmetrical arrangement of perforated and non-perforated containers is adopted; bathroom waterproofing is ensured through factory prefabrication processes to prevent leaks.
• Modular Interfaces: Piping connections adopt quick-connect couplings or flange designs, supporting rapid on-site assembly, reducing welding operations, and improving construction efficiency.
