Design Drawings for Kang (Heated Brick Bed) in Container Houses

Currently, there are no standardized design drawings specifically for kangs in container houses. However, adaptive planning can be carried out by combining the design principles of conventional kangs with the characteristics of container houses. The key points are as follows:

1. Kang Position Selection
Priority should be given to the internal space layout and functional zoning of the container house. It is generally recommended to place the kang near the center of the house or in the main activity area (such as the bedroom) to enhance heating efficiency. At the same time, ventilation needs should be considered to avoid direct opposition between the kang and doors/windows, which could lead to heat loss. If the container house has a multi-story structure, the kang should be avoided in areas with weak load-bearing capacity, and the direction of the flue should be ensured not to conflict with the structural safety of the house.

2. Floor Plan Layout
Container houses are mostly rectangular in structure, and the design of the kang should be coordinated with the overall space. For example, the kang can be arranged along the length of the container, utilizing its narrow and long space to form a continuous heating surface; or, by combining the modular characteristics of the container, the kang can be separated from adjacent functional areas (such as the kitchen or storage room) by partitions, ensuring functional independence while facilitating heat sharing. Sufficient activity space should be reserved to avoid the kang occupying too much area and affecting daily use.

3. Structural Adaptation and Insulation Treatment
The walls of container houses are made of metal, which has high thermal conductivity. Therefore, it is crucial to address the connection and insulation issues between the kang and the walls. Connection Method: A light steel keel frame can be used to fix the kang structure, with the keels anchored to the container walls using expansion bolts to ensure stability. Insulation Treatment: Lightweight insulation materials such as rock wool boards or glass wool can be laid on the contact surface between the kang and the walls to reduce heat transfer to the walls. At the same time, fireproof boards or aluminum foil thermal insulation films can be covered on the outer layer to enhance fire resistance.

4. Roof and Flue Design
Container roofs are mostly flat or sloped, and the design of the flue should ensure smooth smoke exhaust without damaging the roof structure. Flat-roofed houses: A vertical chimney can be installed on the roof, with an anti-backdraft device installed at the bottom of the chimney to prevent cold air from flowing backward. Sloped-roofed houses: Metal flue pipes can be laid along the slope of the roof, utilizing the natural slope to accelerate smoke exhaust. At the same time, waterproof sealing treatment should be carried out at the contact points between the flue pipes and the roof. The interior of the flue should be regularly cleaned of soot to prevent blockage and affect combustion efficiency.

5. Selection of Interior Decoration Materials
Fireproof and insulation materials should be used on the surface and surrounding areas of the kang. Kang Surface: It is recommended to use cement pressure boards or tiles for paving, which are both heat-resistant and easy to clean. Enclosing Structure: The inner layer should be wrapped with fireproof boards, and the outer layer can be fitted with wooden decorative panels to enhance aesthetics. Insulation Layer: Insulation materials such as perlite or expanded vermiculite can be filled inside the kang to reduce heat loss. In addition, maintenance access ports should be reserved around the kang for easy post-maintenance.
