Container House Wall Installation

The installation of container house walls should follow professional steps and pay attention to key details according to different types and scenarios:

I. Pre-installation Preparations

1. Foundation Inspection and Treatment
   Ensure that the ground is level, with an axis dimension deviation not exceeding ±25mm and a wall height deviation of ≤10mm. Select either a brick or concrete foundation based on the site conditions and pre-embed drainage pipes to avoid water accumulation. For example, the construction plan of Zhongnan Steel Structure clearly states that the flatness of the foundation directly affects the stability of the walls.

2. Material Inspection and Handling
   Handle materials with care upon arrival at the site to avoid damaging the steel structures. Focus on inspecting the welding quality, the tightness of the screws, and whether the component dimensions meet the drawing requirements. For example, all screws for assembling square tube columns and steel beams should be tightly fastened.

II. Core Steps of Wall Installation

1. Steel Structure Frame Construction

   • First, install the chassis and fix it to the foundation with expansion screws. Then, assemble the steel beams and square tube columns one by one, using a plumb line to adjust the verticality.
   • Weld the horizontal supports and insert them into the steel beams to ensure the overall rigidity of the frame. For example, the packing boxes of Suzhou Zhongnan adopt a full steel structure frame with a wind resistance rating of up to Level 12, and strict frame precision is required for their wall installation.

2. Wall Panel and Roof Panel Installation

   • Reserve positions for doors and windows during wall panel installation. After the exterior walls are completed, install the roof panels and reserve positions for roof equipment (such as solar panels or lightning rods).
   • Ensure that the connections between wall panels are tight and seamless. After window installation, perform waterproofing treatment, and ensure that the doors are straight and have no gaps with the wall panels. For example, Shanghai Yaotuo Containers emphasizes that sealant should be applied at the joints of wall panels to prevent leakage.

3. Concealed Work Treatment

   • Pre-embed water and electricity lines inside the walls and provide moisture-proof and waterproof layers. For example, apply PVC special floor adhesive before laying the floor and weld the joints of the floor adhesive.
   • Add soundproof and thermal insulation cotton for the thermal insulation layer, especially paying attention to the fact that containers themselves do not have thermal insulation functions.

III. Key Considerations

1. Wind and Earthquake Resistance Design
   For long-term outdoor use scenarios, reinforce the corners with steel frames and build concrete piers at the bottom. For example, the fan village project of the Qatar World Cup adopts the 'factory prefabrication + on-site rapid assembly' mode and ensures safety under extreme conditions by quantitatively collecting the frame deformation rate (only 0.18%).

2. Drainage and Lightning Protection Measures

   • The ground level should be higher than the surrounding area. Dig drainage ditches around the container and cover the top with a 'gable' canopy.
   • Install lightning rods in mountainous and wild areas as iron containers are prone to becoming lightning targets during thunderstorms.

3. Compliance and Safety
   Give priority to products that have passed national certification and avoid using non-standard white-label containers (with a frame deformation rate generally exceeding 1.2%, posing safety hazards). For example, a construction site in Shandong suffered a collapse due to the use of thin steel frame containers during a typhoon, resulting in direct economic losses of over 200,000 yuan.
