Technical Manual For Double-Wing Expandable Container House Product

I.Product Description

1. Product Positioning

The double-wing expandable container house is a modular building with a frame made of high-strength steel, which realizes flexible space conversion through mechanical expansion devices. It combines convenient transportation and comfortable use, and is suitable for multiple scenarios such as temporary residence, construction site offices, emergency disaster relief resettlement, and commercial exhibition halls. Its core advantages lie in the small space occupied during folded transportation; after unfolding, it can achieve a 2-2.3 times space expansion. Moreover, it is prefabricated in the factory and then quickly deployed on-site, significantly reducing time and cost investment.

2. Core Features

Efficient Expansion: Driven by machinery, the double wings unfold synchronously, and installation and shaping can be completed within 15-20 minutes, with the number of repeated folding reaching more than 500 times.

Durable and Economical: It has a service life of over 40 years. Compared with traditional prefabricated houses, it saves two-thirds of the temporary construction costs and reduces transportation costs by 70%.

Superior Performance: It has the characteristics of wind resistance, earthquake resistance, waterproofing, and thermal insulation, and is suitable for complex environments such as plateaus and coastal areas.

Flexible Customization: The internal layout, wall panel thickness, and supporting facilities can be adjusted according to needs.

II. Product Principles

1. Core Expansion Mechanism

A mechanical expansion system is adopted to realize the opening and closing of the side wings:

Expanded State: After activating the expansion device, the side wings are unfolded and flipped along the rails to a vertical position, forming a flat surface with the main container body. At the same time, the side wings are fixed to ensure structural stability.

Folded State: The side wings are retracted and flipped downward, covering both sides of the main container body to form a compact size for hoisting and transportation. The width after folding is only 2200mm, which complies with the standard container transportation specifications.

2. Structural Stability Principle

The frame is made of Q235/Q355 high-strength steel, which undergoes hot-dip galvanizing and electrostatic powder coating to form multiple anti-corrosion protections. The roof and floor adopt a precise load-bearing design, and combined with sealing strips and connecting devices, structural waterproofing and airtightness are ensured.

IV. Key Points for Installation and Maintenance

1. Installation Process

On-site hoisting and positioning → Unfolding the double wings → Fixing the side wings → Connecting water and electricity → Sealing inspection

2.Maintenance Requirements

Check the lubricating oil level of the expansion mechanism quarterly.

Regularly clean the floor drains to prevent the water seal from drying out.

Inspect the grounding reliability of the electrical system every six months.

3.Precautions

Before expansion, confirm that the ground is level (slope ≤ 3‰).

Operation of the expansion module is prohibited in strong wind weather (wind force ≥ Level 7).

Avoid impact on the enclosure wall panels by sharp objects.
