With the intensification of global climate change, extreme weather is frequent, especially natural disasters such as strong winds, typhoons and hurricanes, which put forward higher requirements for the safety of houses. Traditional buildings are often severely damaged by structural design defects, insufficient material strength, or improper construction when faced with strong winds. As a new form of construction, the container house exhibits excellent wind resistance thanks to its modular design, advanced materials and precision construction technology. This article will introduce in detail the design strategies and technical improvement methods of container houses in terms of wind resistance.
1. How to improve wind resistance in the structural design of container houses
(1) Reduce gaps and wind resistance
In wind-resistant design, the shape of the building's exterior is crucial. The sharp corners, protruding eaves, and complex façade design of traditional houses tend to form wind concentration points, increasing wind pressure, which can lead to structural damage. In the design of DXH container houses, wall panels are used as roofs to reduce the protruding parts such as eaves and balconies, and the façade of the house is designed to be smooth and concise, which effectively reduces wind resistance and reduces the impact of strong winds on the building.
Common streamlined design strategies include:
Panel roof design: The use of wall panels as the roof can effectively reduce the gaps in the roof, avoid the direct impact of wind on the roof, and reduce the risk of overturning. At the same time, it can increase the load-bearing and thermal insulation capacity of the roof.
Add more wind-resistant columns: Adding additional wind-resistant columns on different exterior walls can make the whole wall more evenly stressed by the wind and better resist the impact of strong winds, and at the same time, a layer of metal carved panels is laid on the wind-resistant columns to cover the entire detachable container house, and edging pieces are used to cover the joints of the metal carved panels of the two wall panels. Combined with the customized non-perforated corner head, it can greatly improve the wind resistance of the house.
(2) Light steel structure to improve overall stability
Prefab houses usually use light steel structure as the core frame. Compared with the traditional brick-concrete structure, the light steel structure has higher tensile strength and shear strength, which can maintain the overall stability of the house in a strong wind environment and prevent the structure from deforming or collapsing.
The wind-resistant advantages of light steel structures include:
High-strength steel: The light steel materials used in prefab homes are often galvanized to resist corrosion and high strength to withstand extreme weather.
Frame structure: The light steel frame is bolted and nested to form a stable whole, which can effectively resist the horizontal impact and vertical tension of the wind.

(3) Modular design to enhance the integrity of the structure
The detachable container house is modular prefabricated technology, and the individual modules are produced in the factory and subjected to strict quality inspection. The advantages of the modular design are:
High-precision assembly: The connection between the modules adopts high-strength bolts, steel plates and sealing strips to ensure the tightness and wind resistance of the joints.
Monolithic structure: The modules of the detachable container house are assembled on site to form a monolithic structure, which is more resistant to the impact of wind than the brick wall structure of traditional buildings.
2. How to choose materials to improve wind resistance
In the selection of materials, prefab houses focus on lightweight, high strength and durability to ensure that the house remains stable in strong winds.
(1) High-strength wall materials
Composite panels are usually selected for the wall materials of prefab houses, such as:
Magnesium sulfur oxide composite panel: It has the ability of waterproof, fireproof and windproof, and can effectively resist the impact of flying rocks, branches and other debris in the storm.
Polyurethane composite panel: It has good thermal insulation and wind resistance, and has high compressive strength.
These high-strength materials not only improve the wind resistance of the wall, but also reduce the impact of wind pressure on the interior, improving the safety of the occupants.
(2) Windproof glass and window frame design
Windows are the weak link in the wind-resistant design of the house. In strong winds, traditional glass windows are prone to breaking, causing the interior of the house to be damaged by the wind. prefab houses are typically designed with windows that:
Double-layer or three-layer tempered glass: Tempered glass has high impact resistance, and is reinforced with square pipes at the junction of windows and wall panels, which can effectively resist the impact of wind and flying objects.
Aluminium window frames: Compared with traditional wooden window frames, aluminium window frames have higher strength and airtightness, which can reduce wind penetration.

(3) Optimization of roofing materials
The roof is the part of the house that is most susceptible to wind damage. In order to improve wind resistance, the roof of an integrated house usually uses:
Metal roofing panels: Metal roofing panels are usually bolted and have good wind resistance, corrosion resistance and durability.
Windproof fasteners: Use windproof fasteners during the installation of the roof to ensure that the roof panels will not be overturned or displaced in strong wind environments.
3. How to improve the wind resistance of the construction process
In addition to the optimization of design and materials, the construction process is also a key factor in improving the wind resistance of the portable container house.
(1) Foundation reinforcement
In order to prevent the house from being overturned or slid in strong winds, the foundation of the portable container house is usually designed to be reinforced. Common methods of ground reinforcement include:
Ground anchor technology: through screw ground piles or ground anchors, the house is firmly fixed to the ground and increases wind resistance.
Reinforced concrete foundation: In areas with frequent strong winds, the use of reinforced concrete foundation can effectively enhance the stability of the house.
(2) Reinforced connections between modules
During the on-site assembly process, high-strength connectors are used between the individual modules of the prefabricated house, such as:
Bolted joint: The tightness and tensile ability of the bolt can effectively enhance the stability between the modules.
Welding technology: For important connection parts, welding process is used to ensure the connection strength between modules.
4. Application of smart technology
In order to further improve the wind resistance of integrated houses, modern integrated houses have also introduced intelligent monitoring technology. Through the installation of wind sensors and structural monitoring systems, the force of the house can be monitored in real time, and strong winds can be warned in advance to ensure the safety of residents.
Conclusion:
With its modular design, advanced materials and high-precision construction technology, detachable container homes excel in improving wind resistance. By optimizing the structural design, material selection and construction process of the house, the integrated house can not only effectively resist strong winds, but also provide a safe, stable and comfortable living environment for residents. In the future, with the further application of intelligent technology, the wind resistance of detachable container houses will continue to improve, becoming an ideal housing choice in extreme weather environme
