With the development of urban commercialization, many large and medium-sized shopping malls, office buildings, KTV private rooms, hotels and other buildings are rapidly emerging. Taking into account factors such as sound insulation, easy installation, and price, many enterprises use movable partition walls for space separation. Partition wall design is widely used in the interior decoration of modern buildings. Therefore, the reasonable selection and installation of partition materials will directly affect the carrying capacity of buildings, the safety of evacuation of personnel during fires, fire protection zones, fire detection and alarm areas.
The movable partition wall can be divided into three types according to its structure: block partition wall, skeleton partition wall and panel partition wall. According to fire performance, building partitions can be divided into non-fire partitions and fire partitions. Fire partitions can be divided into two types: fire partitions and non-load-bearing firewalls. The fire resistance of non-load-bearing firewalls can reach more than 3 hours. The fire protection zoning shall meet the specifications of different fire protection requirements and have fire protection functions. It should be set strictly according to the specifications.
1. Block wall
The movable partition wall is a non-load-bearing partition wall composed of various blocks. Block partition wall is mainly composed of clay brick partition wall, block partition wall, hollow brick partition wall and so on. When the thickness of the partition wall is the same, the fire resistance depends on the type of block. Different types of partition walls have different fire resistance. Another factor affecting the fire resistance of the partition wall is the block method. The fire resistance ratio of the empty partition wall is lower than that of the filled partition wall. The block partition wall has high fire resistance and good thermal performance, but its unit density is larger than other types of partition walls.
2. Skeleton partition
Skeleton partition wall is a lightweight partition wall composed of skeleton and panel. The column partition wall structure is flexible, can be installed to any height and thickness, and can be filled with fire insulation materials. According to the bolt type, the bolt partition wall can be divided into steel bolt partition wall, wood bolt partition wall and gypsum bolt partition wall.
The flammability of the bolt material affects the fire resistance. The steel bolt partition wall has the best fire resistance, followed by the gypsum bolt partition wall, and the wooden bolt partition wall is the worst. The type and thickness of the wallboard material also affect the fire resistance of the partition wall. For non-combustible material panels, the greater the thickness, the better the fire resistance. The fire resistance of 15 mm double-layer fire-resistant gypsum board is 2.00 hours, and the fire resistance of 12 mm fire-resistant gypsum board is 1.00 hour: the fire resistance of steel bolt partition wall is 1.50 hours and 0.90 hours, respectively.
Therefore, under the same conditions, wood bolts have better fire resistance than steel bolts, so it is necessary to provide necessary fire protection for steel bolts. The structure of the skeleton partition wall, such as packaging thickness, fire prevention, wall decoration, etc., will also affect the fire resistance of the skeleton partition wall. The skeleton partition wall material can meet the requirements of light weight, sound insulation, heat insulation, fire prevention and waterproof, and is easy to disassemble.
