Tongchuan Container House Design

The design of container houses in Tongchuan requires comprehensive planning that takes into account functional requirements, structural safety, material characteristics, and localized service resources. The following elaborates on this from three dimensions: design essentials, material selection, and utilization of localized resources.

I. Core Design Essentials

1. Functional Adaptability
   The design of container houses must clearly define their usage scenarios, such as temporary offices, residences, commercial operations (e.g., milk tea shops, homestays), or warehousing. For example, Shaanxi Huateng Box-type Mobile House Co., Ltd. offers packing-box units that can be modularly combined to flexibly divide spaces like office areas, dormitories, and conference rooms. Qihong Integrated Housing Co., Ltd., on the other hand, designs mobile panel houses with corridors for construction site needs, integrating security doors and fire-resistant floors to meet safety and convenience requirements.

2. Structural Safety
   The design must comply with building mechanics standards to ensure earthquake resistance, wind resistance, and load-bearing capacity. Local enterprises in Tongchuan mostly adopt galvanized steel frame structures. For instance, Huateng's products use cold-formed galvanized steel members paired with bolt connection technology to avoid deformation risks associated with traditional welding. Qihong enhances earthquake resistance through a fully steel welded structure, with products capable of withstanding over 20 years of use.

3. Environmental Protection and Energy Efficiency
   Preference should be given to non-combustible or flame-retardant materials, such as sandwich panels and rock wool boards, to improve fire resistance. Air insulation design or double-wall structures can enhance sound and thermal insulation. For example, a container warehouse in Yintai District, Tongchuan, achieves energy efficiency through air insulation design, while Huateng's packing-box units use entirely non-combustible materials for their enclosure, meeting environmental standards.

II. Material and Process Selection

1. Main Structural Materials
   Galvanized steel serves as the primary frame, complemented by color steel plates or sandwich panels as enclosure materials. Huateng's packing-box units feature profiles with a thickness of 2.3 cm and a width of galvanized special-shaped sections, incorporating built-in drainage slots to reduce errors. Qihong uses a combination of fire-resistant boards and flame-retardant foam boards to enhance safety.

2. Connection and Assembly Processes
   Bolt connections or quick-assembly techniques are employed to avoid on-site welding, reducing construction difficulty and costs. Huateng's packing-box units are fully screw-assembled, allowing ordinary workers to operate them. Four standard units can be packed into 1/4 the volume of a 20-foot container, facilitating transportation. Qihong's mobile houses feature modular designs that support horizontal and vertical combinations to form stacked spaces.

III. Utilization of Localized Resources

1. Supplier Collaboration
   Tongchuan boasts several professional enterprises offering integrated design, production, and installation services. For example, Shaanxi Huateng Box-type Mobile House Co., Ltd. covers Shaanxi and the Northwest region, providing full-process services from scheme design to after-sales warranty. Tongchuan New Area Yonggu Steel Structure Engineering Co., Ltd. holds container modification qualifications and can customize special-function houses.

2. Second-hand Resource Utilization
   Second-hand railway container trading markets exist in Tongchuan and surrounding areas (e.g., Xi'an), with prices ranging from 6,500 to 7,000 yuan, suitable for budget-constrained projects. Modified second-hand containers can be used for warehousing or temporary buildings, but structural integrity (e.g., rust, deformation) and airtightness must be thoroughly inspected.

3. Policy and Regulatory Support
   Design must comply with local building codes in Tongchuan, such as fire protection drawing submissions and construction drawing approvals. Local enterprises (e.g., Huateng, Qihong) are usually familiar with approval requirements and can assist in drawing design and compliance submissions, shortening project cycles.
