Other pipes should not pass through the firewall, and when they must be crossed, the voids around them should be filled with non-combustible materials. The insulation material of the pipe passing through the firewall should be made of non-combustible material.

4. When the pipeline passes through the partition wall and floor, the gap around it should be filled with non-combustible materials. The partition wall in a high-rise building should be built to the bottom of the beam slab and should not leave gaps.

5. The equipment room, ventilation and air-conditioning room of the automatic fire extinguishing system located in the high-rise building shall be separated from other parts by partition walls with fire resistance limits not lower than the fire resistance limit.

6. Building height.

For high-rise buildings not exceeding 100m, cable wells and pipeline wells should be separated by non-combustible bodies equivalent to the fire resistance limit of the floor slabs every 2 or 3 floors. The voids of cable wells, pipe wells and rooms, walkways, etc., should be filled with non-combustible materials. The wall of the well shall be a non-combustible body with a fire resistance limit not lower than that; The inspection door on the wall of the inspection well should be a Class C fire door.

7. The garbage chute should be set up against the outer wall, and should not be located in the stairwell. The exhaust vent of the garbage chute should be opened directly to the outside. The garbage hopper should be located in the front room of the garbage channel, and the front room should be equipped with a Class C fire door.

8. The fire doors of walkways, stairwells and front rooms used for evacuation should have the function of self-closing. Double and multi-leaf fire doors should also have the function of sequential closing. Normally open fire doors, when a fire occurs, should have the function of self-closing and signal feedback.

9. Fire shutters set on the evacuation walkway.

Opening and closing devices should be provided on both sides of the roller shutter and should have automatic, manual and mechanical control functions.

In order to strengthen the fire safety management of high-rise civil buildings, prevent fires and reduce fire hazards, these regulations are formulated in accordance with the "Fire Protection Law of the People's Republic of China" and other laws, administrative regulations and relevant regulations.

Regulations on Fire Safety Management of High-rise Civil Buildings

Article 2 These provisions apply to the fire safety management of high-rise civil buildings (including high-rise residential buildings and high-rise public buildings) that have been completed and put into use in accordance with the law.

Article 3 The fire safety management of high-rise civil buildings implements the principle of giving priority to prevention and combining prevention and elimination, and implements a fire safety responsibility system.

High-rise civil buildings with a building height of more than 100 meters should implement stricter fire safety management.

Legal analysis: 1. There should be at least two places in the annular fire lane that are connected with other lanes.

2. The end of the fire lane should be set up with a return lane or a return yard, and the area of the return yard should not be less than 12mx12m, and for high-rise buildings, it should not be less than 15mx15m; The area of the return yard for large fire trucks should not be less than 18 18 square meters.

3. When the fire lane passes through the door opening of the building, its net height and net width should not be less than 4 meters; The net width between the door stacks should not be less than meters.

Legal basis: Article 48 of the Land Management Law of the People's Republic of China Where land is expropriated, compensation shall be given in accordance with the original use of the expropriated land. The compensation fee for the expropriation of cultivated land includes land compensation fee, resettlement subsidy fee, and compensation fee for ground attachments and green cherry seedlings.

The land compensation fee for the expropriation of cultivated land shall be six to ten times the average annual output value of the cultivated land in the three years prior to the expropriation. The subsidy for the resettlement of cultivated land shall be calculated according to the number of agricultural population to be resettled. The number of agricultural population to be resettled shall be calculated by dividing the amount of cultivated land expropriated by the average amount of cultivated land occupied by the expropriated units before land requisition.

The standard of resettlement subsidy for each agricultural population to be resettled shall be four to six times the average annual output value of the cultivated land in the three years preceding the expropriation. However, the resettlement subsidy per hectare of expropriated cultivated land shall not exceed 15 times the average annual output value of the three years preceding the expropriation.

High-rise civil building fire safety management regulations: high-rise civil building fire control and destruction room to implement a 24-hour daily duty system, each shift should not be less than 2 people, and each shift working time should not exceed 8 hours, can be through the urban fire remote monitoring system to achieve remote operation of all control functions of the fire control room, each shift should not be less than 1 person.

Article 26 of the Regulations on Fire Safety Management of High-rise Civil Buildings.

The fire control room of high-rise civil buildings shall be managed by it, and a 24-hour duty system shall be implemented in place, and each shift shall not be less than 2 personnel on duty. The operators on duty in the fire control room shall obtain the corresponding level of professional qualification certificate for the specific type of work in the fire protection industry in accordance with the law, be proficient in the fire alarm disposal procedures and requirements, and check the operation of automatic fire protection facilities and linkage control equipment in accordance with the relevant provisions to ensure that they are in normal working condition. The fire control room shall keep the general layout of high-rise civil buildings, floor plans and fire protection facilities system diagram and control logic relationship description, building fire protection facilities maintenance records and test reports and other information.

Code for Fire Design of Buildings This code is formulated in order to prevent and reduce building fire hazards, protect the safety of people and property, and prevent and reduce fire hazards. So what are the contents of the latest building fire code? The following is the relevant interpretation of the building fire code by Zhongda Consulting:

Recently, the new version of the national standard "Code for Fire Protection Design of Buildings" (GB50016-2014) was promulgated, which will be implemented from May 1, 2015.

The new code merges the Code for Fire Protection Design of Buildings (GB50016-2006) and the Code for Fire Protection Design of High-rise Civil Buildings (GB50045-95 (2005 version)), and the main changes in the new code are as follows:

1.The requirements for the inconsistency between the two standards have been adjusted, and the classification of residential buildings has been unified according to the building height;

2.Two chapters on fire fighting and rescue facilities and wood structure buildings have been added, the requirements for fire fighting and rescue have been improved, and the fire protection requirements for wood structure buildings have been systematically standardized.

3.Supplementing the fire protection requirements of the external thermal insulation system of the building;

4.The setting of fire-fighting facilities is an independent chapter and the relevant content is improved; Cancel the requirements for the design of fire water supply system and smoke prevention and exhaust system, and make provisions by the corresponding national standards;

5.The fire protection technical requirements for high-rise residential buildings and high-rise civil buildings with a building height greater than 100m have been appropriately improved;

6.Supplemented the fire protection requirements when using covered pedestrian streets for safe evacuation; adjusted and supplemented the design staff density of building materials, furniture, lighting stores and exhibition halls;

7.The fire protection requirements of underground warehouses, logistics buildings, large combustible gas storage tanks (areas), liquid ammonia storage tanks, and liquefied natural gas storage tanks have been supplemented, and the fire spacing of liquid oxygen storage tanks has been adjusted;

8.The requirements for preventing the vertical or horizontal spread of building fires have been improved.
