Hebei Container House Standard

The Hebei container house standard mainly covers aspects such as design, materials, structure, performance, and construction acceptance, as detailed below:

Design and Acceptance Basis

It is necessary to comply with current national, industry, and local regulatory standards, as well as the construction plan confirmed by Party A. The explicitly required standard is the 'Technical Standard for Temporary Buildings in Construction Projects' (DB11 - 693 - 2017). If there is an update, the latest version shall be followed. At the same time, it should meet the general product quality requirements of the movable panel house industry and satisfy Party A's normal usage needs.

Material Standards

• Thermal Insulation Materials: They should meet the requirements of national and project location standards regarding oxygen index and flame retardancy. The oxygen index (OI) should not be lower than 30, and the combustion performance rating should reach Class A or above. Additionally, the materials should comply with environmental protection requirements to safeguard the health of users.
• Rock Wool Panels: For the rock wool partition panels in the house, columns must be installed for support at the first layer in the middle section. The thickness of the iron sheets of the rock wool partition panels should be no less than 0.5mm and be flat without deformation. The thickness of the iron sheets of the rock wool exterior wall panels should be no less than 0.5mm. After installation and acceptance, the overall panels should be flat without any deformation or unevenness. The raw materials of the rock wool exterior trim panels entering the site must comply with relevant national quality standards, and the material quality should be defined according to the mutually agreed standards of both parties.
• Other Materials: The thickness of the roof truss steel beam material, the thickness of the column C-shaped steel material, the truss material, steel stairs, and doors and windows should comply with relevant national quality standards, with positive and negative errors within the specified range. The thickness of the ground cement fiber board material should be no less than 18mm, and the thickness of the decorative panel should be no less than 2.0mm. After installation, the overall settlement at the center position should be no more than 1cm. Qualified panels should be used, and the anchor screws must be tightly fastened.

Performance Standards

• Structural Safety: It is essential to ensure structural safety, with all parts firmly installed, free from deformation and open welds. It should be able to cope with weather changes in different seasons and meet basic requirements such as fire prevention, thermal insulation, wind resistance, and earthquake resistance.
• Load Standard: The standard value of the live load on the floors of dormitories, offices, and other buildings should be taken as 2.0kN/㎡.
• Usage Comfort: It should have basic thermal insulation capabilities to ensure居住 (living) comfort. At the same time, it should support rapid assembly and be able to match the project schedule.
