12.0.1 The fire protection design of low-rise cold-formed thin-walled steel buildings (light steel villas) shall not only comply with the provisions of this Regulation, but also comply with the relevant provisions of the current national standard 'Code for Fire Protection of Building Design' GB50016. 12.0.2 The following parts in the light steel villa building shall be separated from other parts by non-combustible walls and floor plates with a fire resistance limit of not less than 1.00h (mandatory requirements): 1. Power distribution room, boiler room, motor vehicle garage. 2 database (room), archives (room), storage room. 3 communal kitchens. 12.0.3 For a motor vehicle garage attached to a cold-formed thin-walled steel residence (light steel villa) and used only for the residence, the door connected to the living part shall be a Class B fire door, and the partition wall of the garage shall be within 100mm of the ground. No openings should be made. 12.0.4 The horizontal spacing between the closer edges of door and window openings on both sides of the wall between residential units shall not be less than 1.0m. 12.0.5 For a cold-formed thin-walled steel building (light steel villa) composed of different heights, the smaller distance between the skylight on the roof of the lower part and the door and window openings on the outer wall of the higher part should not be too small. less than 4.0m. When one of the following conditions is met, the distance may not be limited: 1. The lower part is equipped with an automatic sprinkler system or the skylight is a fixed Class B fire window. 2 The doors on the outer walls of the higher part are Class B fire doors that can be automatically closed in case of fire, and fixed Class B fire windows are provided at the windows and openings. 12.0.6 The vertical exhaust pipes of bathrooms, toilets and kitchens shall take measures to prevent backflow or set fire dampers on branch pipes. A fire damper with an operating temperature of 150 degrees Celsius should be installed at the branch pipe connecting the oil fume exhaust pipe and the vertical exhaust pipe in the kitchen. 12.0.7 When pipelines in buildings pass through floors, walls between residential building units and household walls, fire-proof sealing materials shall be used to fill the gaps tightly; when the crowns are made of flame-retardant or combustible plates, two holes shall be installed at the penetration parts. Fire prevention measures are taken on the side. 12.0.8 Fire alarm devices can be installed in low-rise cold-formed thin-walled steel residences (light steel villas). The following is the description of this chapter: 12.0.1 This article specifies the scope of application of the fire protection design of this regulation, and clarifies the relationship with the current national standard 'Code for Fire Protection Design of Buildings' GB50016. Cold-formed thin-walled steel buildings (light steel villas) have their own structural characteristics, and the provisions of this chapter should be implemented in the fire protection design of buildings. For those not specified in this chapter, such as the fire resistance rating of the building, fire separation distance, safe evacuation, fire protection facilities, etc., it shall be designed in accordance with the relevant provisions of the current national standard 'Code for Fire Protection of Building Design' GB50016. 12.0.2, 12.0.3 This article specifies the fire separation requirements for the more dangerous places attached to cold-formed thin-walled steel residential buildings (light steel villas) and other parts of the building. For the doors and windows opened due to the needs of use, appropriate fire protection measures should be considered. In order to prevent the fuel vapor leaked from the motor garage from entering the residential part, it is required that no holes should be opened on the partition wall within 100mm of the garage floor. In the case of a large number of vehicles, or the fire protection design of the garage that is not only used for the residence, the fire protection design should be implemented in accordance with the provisions of the 'Code for Fire Protection Design of Garages, Repair Garages, and Parking Lots' GB50067. 12.0.4 In order to prevent adjacent units from being affected by fire smoke when a fire occurs in a light steel villa residence, this article specifies the horizontal distance between the closer edges of the windows on both sides of the wall between units. In addition, the wall between the units should be built to the bottom of the roof panel, so that the partition wall can really play the role of fireproof partition, so as to limit the fire to one unit, prevent the spread and reduce the loss. In unit dwellings, the walls between units should be free of door and window openings for fire separation purposes. If the fire resistance of the roof panel cannot meet the corresponding requirements, it is necessary to consider measures such as taking partition walls out of the roof to prevent the spread of fire between units. 12.0.5 This article is mainly to prevent the flame from rapidly burning through the skylight and spreading to the wall of the higher part of the building during a fire. Setting up automatic sprinkler systems or fixed fire windows can effectively prevent the spread of fire. 12.0.6 In order to prevent the fire from spreading through the vertical exhaust ducts (natural exhaust or mechanical exhaust) of the bathrooms, toilets and kitchens in the light steel villa building, it is required that the vertical exhaust ducts in these parts should take anti-reflux measures or be installed in their branch pipes. Install fire dampers. Due to the high temperature of the exhaust gas discharged from the normal operation in the kitchen, if a fire damper that operates at 70 degrees Celsius is set on the vertical exhaust pipe, it will affect the exhaust air in the usual kitchen operation. , This article stipulates that the connection between the branch pipe of the lampblack exhaust pipe and the vertical exhaust pipe of the light steel residential kitchen should be equipped with a fire damper that operates at 150 degrees Celsius. 12.0.7 Pipes such as water pipes in the light steel villa residential building must be limited by conditions. When passing through walls between units and division walls,Use non-combustible materials such as cement mortar or fire-resistant materials to tightly fill the gaps around the pipes. For pipes made of materials such as plastics that are prone to shrinkage, deformation or ablation when exposed to high temperature or flame, in order to reduce fire and smoke from passing through the fire burp body, measures should be taken to enable such pipes to be sealed after being exposed to fire. Thermal expansion type flame arrester, etc. 12.0.8 Considering that the users in the residence may be in a sleeping state, a fire alarm device should be set up, which can alarm in time when a fire occurs, and provide favorable conditions for the safe escape of the personnel.
