fireproof prefabricated houses

Introduction to fireproof prefabricated houses

Fireproof prefabricated houses are a type of prefabricated houses with fire resistance. It has many excellent characteristics, including but not limited to easy installation, high flexibility, good insulation, good weather resistance, good fire resistance, reasonable price, reusability, strong adaptability and beautiful appearance. This type of prefabricated house uses color steel plates as the skeleton and sandwich panels as the enclosure material. The space combination is combined with standard modular series and bolt components for quick assembly and disassembly. It not only realizes the universal standardization of temporary buildings, but also establishes the concept of environmental protection, energy saving, fast and efficient construction, and becomes a standardized product with serialized development, integrated production, supporting supply, inventory matching and multiple turnover. ‌

Characteristics of fireproof prefabricated houses

The fire resistance of prefabricated buildings is one of its important characteristics. By using specific refractory materials and refractory technologies, the spread of flames and fire hazards are effectively prevented, thereby ensuring the safety of users. In addition, this type of prefabricated house also has good sealing performance, which can effectively prevent wind and rain from entering the room. It is also equipped with windproof brackets and fixings to ensure stability under severe weather conditions. ‌

In terms of fire prevention measures, the mezzanine of the prefabricated house should meet the A-level fire protection requirements, such as the use of flame-retardant rock wool materials, and the thickness and rigidity of the color steel plate should also meet the requirements. In addition, the distance between the prefabricated house and dangerous sources such as warehouses for flammable and explosive items should not be less than 25m to reduce safety hazards. The demolition of the prefabricated house shall be undertaken by a construction unit with corresponding qualifications. Before the demolition construction, a demolition construction plan and various safety and technical measures should be formulated and implemented to ensure construction safety. ‌

There are usually several types of fireproof materials for prefabricated houses

Glass wool: Glass wool is a very common thermal insulation material that can not only effectively prevent fires, but also has a very good thermal insulation effect.

Refractory rock wool: Refractory rock wool is a high-efficiency fire-resistant thermal insulation material with excellent fire resistance, which can effectively prevent the occurrence of fire accidents.

Magnesium oxide board: Magnesium oxide board has excellent fireproof performance and can effectively resist the invasion of fire. At the same time, it can also be used as a wall panel material to provide pressure support.

Fireproof coating: Fireproof coating can form a layer of fireproof barrier on the wall and play a certain fireproof role. It is commonly used for fireproof treatment of roofs, walls, steel structures and other parts of prefabricated houses.

Choosing suitable fireproof materials can effectively improve the safety of prefabricated houses and reduce the probability of fire accidents. Selection and construction need to be based on actual conditions.

Standard Specifications for Fireproof Mobile Houses

Fireproofing Grades of Commonly Used Materials

1. Steel: There is no fireproofing grade. However, some special-purpose steels, such as steel used for fireproof doors, can be specially treated to enhance their fire resistance.

2. Sandwich panels: Generally, B1-grade fireproofing materials are used, but A-grade, B2-grade and other materials are also used. Among them, A-grade sandwich panels have the highest fireproofing grade, but the price is relatively high.

3. Fiberglass: B1 or A2-grade materials are usually used.

4. Gypsum board: The commonly used fireproofing grade is A2.

5. Light steel keel: The light steel keel itself has no fireproofing grade, but if it is outer packaged with sandwich materials with good fire resistance, the entire system can reach B1 or A-grade fireproofing grades.

Standard prefabricated house size

Colored steel activity rooms generally use double-sided color steel 5cm thick EPS composite board as wall panels. The most common colors are milky white for the exterior wall and white-gray for the interior wall. Other colors can also be customized. The ground beams, columns, herringbone beams, and straight beams are mainly processed and welded with No. 8 C-shaped steel, and the floor is processed with 15mm thick wood plywood.

The standard size is the outer size plus 160mm. For example, the commonly used width of the gable is 3800mm for 2K, 5620mm for 3K, 7440mm for 4K, and the building interval is 3640mm.

If the 3K * 2K * 3P house has only one room, then the outer wall size of the gable is 5620mm, and the outer wall size in the opening direction is 3800mm.

Of course, the convenience of prefabricated houses lies in their flexible combination, and various sizes can be customized.
