Design of Container Houses in Dongcheng District
The design of container houses in Dongcheng District requires comprehensive consideration of factors such as compliance, spatial planning, climate adaptation, and safety details. Here are the specific design points:
Compliance: It is necessary to strictly follow the 'Beijing Temporary Construction Project Management Measures'. The site selection should avoid urban roads, green spaces, and permanent building red lines. The height should not exceed 2.8 meters, and the area of a single container should be ≤15㎡. Before design, it is required to register with the local street or park management committee and provide site usage certificates to ensure legal compliance.
Spatial Planning: Choose between a compact or multi-functional design based on needs. The compact version (10㎡ single container) can achieve an integrated 'sleeping + storage' space, with 30cm of storage space reserved under the bed and a foldable table installed on the wall (60cm wide when unfolded and 30cm when folded) to save space. The multi-functional version (20㎡ double containers spliced) has a bedroom and open kitchen in the front container and a bathroom area (waterproof walls + folding toilet) in the rear container, with a glass partition in the middle for ventilation and lighting, meeting diverse functional needs.
Climate Adaptation: The walls are made of 10cm thick rock wool sandwich panels (thermal conductivity ≤0.04W/(m·K)), which warm up quickly by 2℃ in winter. The roof is equipped with an openable aluminum alloy skylight (with a sunshade), and the side walls have 30cm×50cm ventilation openings (with insect screens). In summer, a combination of opening windows and using fans can reduce the perceived temperature by 3-5℃. The floor is laid with a 3cm thick insulation layer + 2cm anti-slip tiles to enhance winter comfort.
Safety Details: In terms of fire protection, one ABC dry powder fire extinguisher should be provided for every 10㎡. The electrical circuits should be laid in concealed conduits + flame-retardant pipes, and private connections are strictly prohibited. The electrical design should include dual-circuit power supply (including emergency sockets), with a separate 16A circuit for the kitchen. High-power equipment (such as refrigerators and water heaters) should have separate switches. The doors and windows should be made of 5mm tempered glass doors (with C-level lock cylinders), and anti-theft chains should be reserved on the windows to ensure anti-theft safety.
Appearance and Integration with the Surroundings: The exterior walls can be pasted with imitation brick texture real stone paint (off-white/light gray) or wood veneer panels + green plant walls. A 15cm wide eave should be added on the top for sunshade and rain protection, and vine planting slots should be reserved on the walls (reducing the temperature by 1-2℃ in summer). Reflective strips or park-specific numbers should be printed on the sides of the containers, taking into account both compliance and management convenience.
Structural Safety and Wind Resistance: Choose containers with fixing devices at the bottom to prevent movement or overturning caused by winds of level 8 or above. Before customization, verify the conditions of lifting and transportation channels to ensure that the column wall thickness is ≥2.3mm and the frame is fully welded, meeting the load and anti-overturning standards of JGJ/T 435-2018.
Material Environmental Protection and Fire Resistance Performance: The core material of the sandwich panels must be Class A non-combustible material (rock wool or glass wool), and the use of EPS polystyrene foam is strictly prohibited. Welding operations around the containers are prohibited, and high-temperature-resistant sleeves should be added to metal pipes passing through the walls. The enclosure structure mostly uses cotton color steel plates, and the frame keels are made of galvanized square steel pipes. Manufacturers are required to provide material environmental protection certificates to ensure no emission of harmful substances and no pollution during the construction process.
