Container Mobile House Joint
The container mobile house joint is a key component used to connect various structural parts of container houses. Common types include corner joints and connecting hardware fasteners. Most of these joints are made of steel, with some undergoing fire-resistant and anti-corrosion treatments, directly affecting the structural stability and safety of the house.
Types and Functions of Joints
Container mobile house joints can be classified into corner joints, edge connectors, base connectors, etc., based on their connection positions and functions. Corner joints are the most common type, used to connect the columns and beams of containers. They typically employ square tube welding processes and are surface-painted to enhance corrosion resistance. For example, white-painted packing box corner joints and quick-assembly box upper and lower corner joint connecting hardware fasteners all fall into this category. Connecting hardware fasteners are used to secure the joints between adjacent containers, ensuring the overall structural stability.
Material and Process Requirements
The material of the joints directly affects the durability and safety of container houses. High-quality joints are mostly made of high-strength steel, such as Q235 or Q345, with welds meeting the GB/T 19001-2016 standard to ensure wind and earthquake resistance. For example, the container activity houses of Suzhou Zhongnan Steel Structure Co., Ltd. adopt a full steel structure frame with exquisite corner joint welding processes. Under the action of a 12-level strong wind, the maximum deformation of the frame is only 2mm, far below the national standard limit. In addition, some joints undergo fire-resistant treatments with a fire rating of B1 or above, effectively delaying the spread of fire.
Selection and Installation Considerations
When selecting joints, it is necessary to pay attention to the manufacturer's qualifications and product certifications. Compliant manufacturers should possess domestic and foreign certifications, such as ISO quality management system certification and CE certification, to ensure that their products meet building safety regulations. During installation, it is essential to strictly follow operational procedures to avoid structural looseness due to improper jointing. For example, quick-assembly boxes adopt a modular design and can be assembled by bolting the corner joints without complex welding processes, improving installation efficiency and reducing safety risks.
Market Applications and Trends
With the development of the modular building industry, the joints of container mobile houses are also constantly being upgraded. Leading manufacturers are improving the design of joints to increase the number of times a house can be repeatedly assembled and disassembled. For example, the quick-assembly box products of Suzhou Zhongnan can be repeatedly assembled and disassembled more than 15 times, with the cost per use being only one-third of that of a brand-new product. In addition, the trend towards miniaturization and standardization of joints is evident, facilitating transportation and storage and further reducing overall costs.
