Highrise is the 10 tier and 10 storey residential buildings (including the first-tier set of business service network of residential) and building height more than 24 metres and two levels above the public building and a height exceeding 24 m two-tier and two-storey house, Treasury. Along with the rapid development of the Socialist market economy, the pace of modern urban construction, high-rise buildings in China, in China's great wall inside and outside the country. Only as far as Guangzhou statistics, there are about 7000 high-rise building, 100 meters above the sea level there are 360 super high-rise building. In 1992, the country completed skyscraper is 13000 buildings, height more than 100 m high building only 70 blocks. Due to the high-rise building fires was on fire, evacuation difficult, fighting is difficult, many fire etc. characteristics, national on high-rise building fire safety design and fire safety management strict technical specifications and regulatory requirements. Fire safety design of tall building of many years of practice, as well as the occurrence of painful Highrise lessons, people have enough knowledge, but for high-rise building construction construction site but failed to build due to fire, and construction units and departments of sufficient importance, the high-rise building construction site fire occurred from time to time, to people's lives and property of the tremendous threats.

Data show August 2002-October, Nanjing occurs fenghui mansion, huijie Plaza, and so many high-rise building site fire. 29 October 2004, 4: 00, Shanxi Taiyuan slope child street 15, a construction of high-rise residential building site 13-fire. 17 January 2005 15: 00 am, the most prosperous region in Nanjing at the mouth of the mountain a high-rise construction sites for welders welding sparks when the job falls below the elevator on the ignite flammable of tarp tarpaulin disaster, persuaded to stop watching caused. 25 April 2005 1: 00 am, Henan development building fire, the 120-metre-high building, very difficult to fight. May 11, 2005 14: 20, Hebei province Shijiazhuang city administration of high-rise office building construction site in case of fire. June 7, 2005 1: 53 am, Shanghai jiangpu, zizania Park Road junction, a building under construction in high-rise buildings by electric welding sparks ignite fire protection mesh nylon. 2 August 2005 8: 50 cent, Zhejiang Hangzhou new Toro day • wind up behind the times building, a building of 15 floors high-rise building site in case of fire. November 13, 2005 2: 40 am, Shanxi Taiyuan Nanneihuan Street is construction of wealth building, 13th floor, fire, fire officers and soldiers fight to control the fire until dawn, the building, 12, 13 two-layer was burnt, according to the survey, 12, 24: 00, some workers welding job. December 2, 2005 21: 52, Henan province, Zhengzhou city, the three-way and weier road intersection a 20-storey building in the 65-metre high building site in case of fire, fire officers and soldiers to fight in a timely manner, and evacuation of workers, 16. Therefore, through this high-rise building site fire accidents, strengthening on high-rise building site fire danger and fire response analysis of extremely important.

1. high-rise construction construction site fire risk analysis

First, welders are thrown high-rise construction construction site the "culprit" fire. High-rise building construction, on-site rebar connections, ventilation, heating, water supply and drainage equipment installation, pipe connections, and projects are widely used in decoration of welders, welding operations Sparks, hot melt beads splash scattered, very easily lead to fuel combustion, causing fire. I see a lot of high-rise building construction site in case of fire, electric welding jobs fire of more than 90%.

The second is the high-rise building construction site where a large number of flammable and combustible materials, to provide necessary conditions for the fire. High-rise building construction site where a large number of linoleum, wood, foam board, paint, adhesive and protective NET, insulation materials, and other flammable and combustible materials, such as exposure to open flame of fire, a fire can occur.


The third is the high-rise building construction site Windows and doors, staircases, various types of pipe wells, holes not closed, air horizontal, vertical circulation quickly, chimney effect obvious, in the event of fire, the fire development quickly, spread quickly around, in the short time it is possible to set up a body of the extensive development of fires.

4 fire forces fire rescue is difficult. Due to the high-rise building construction site around the complex, special fire-fighting vehicles difficult to close to high buildings, plus the construction Interior uncompleted opened automatically fire facilities, fire-fighting water scarcity, water pressure, when the attack to satisfy the need for fire, causing the high-rise building construction site fire suppression of great difficulty, particularly in the construction of a late-occurring in the middle and upper even top fire, fire extinguishing is more difficult.

Fifth, the construction of evacuation difficult. High-rise building construction site stairs, evacuation signs, emergency lighting, evacuation facilities did not complete, if there is fire, plus a variety of on-site storage, the hole is not blocking building materials, both for builders or fire rescue workers, evacuation and rescue in difficulty are very large, very easily lead to loss of life.

VI is the high-rise building construction jobs, construction workers face, fire potential risk areas, coupled with the construction of many leaders still do not fully understand and be familiar with the characteristics of a high-rise building and the fire of fire, when the construction site of a fire, often lack the experience and capacity of emergency treatment, resulting in inefficient easy conductor fighting small fire causing disaster. The lack of fire safety of construction workers, thought not ready, if the construction units and lack of appropriate fire-fighting, evacuation preCase and the Organization of construction workers for the walkthrough, in the event of fire, more flustered helpless, will result in the confusion of evacuation.

2. high-rise construction construction site fire fire prevention measures.

First, the construction units to establish fire safety of construction site, the organization responsible for defining the rules and regulations for construction site fire safety, fire safety practice and fire-fighting, evacuation emergency plans; responsible for construction site daily fire safety checks and inspections; organization of emergency fire evacuation drill and fire safety of construction workers; education and training is responsible for construction site fire equipment equipped and maintenance; supervise the implementation of construction site fire hazard rectification work.

The second is the construction unit according to the high-rise building construction in all phases of installation, decoration, timely submission of corresponding fire prevention and emergency plan, and implement walkthrough in place.

Third, the strict implementation of fire safety regulations and procedures for fire safety. To put the fire responsibility in every construction of specific charge and each construction personnel. Strengthen the site check up inspections to check the fire safety regulations and fire safety procedures are in place, the timely detection of fire hazards, implement and supervise reform personnel, careful rectification.

Fourth, strengthen the construction site of ignition and power management. High-rise building construction during the temporary electricity lines, welding, electric Planer, electric saws, drills, electric equipment, paint, etc. using blowtorch flame technology to manage the power supply and the open fire, is strictly prohibited without authorization and privacy la chaos power, unauthorized use of the open fire, is strictly prohibited to smoke in the construction site.

The fifth is to focus on preventing welders to strictly manage the object. Welders should strictly implement the People's Republic of China Fire Services Act, the organs, organizations, enterprises and institutions to fire safety management regulations and other regulations that implement various security measures. Level of the job, you must use the alternate fire damper, shaft, cracks, holes, a job, you should use the next fire bucket, prevent electric welding sparks spilled into the lower work surface.

Sixth, strengthen the construction site of combustible, flammable materials management. Materials management to fixed positioning, fixed people management, classification, storage, away from the power supply and the ignition source. Renovation site of sawdust, sawdust, various combustible packaging to keep clean.

Seven is equipped with all adequate temporary fire fighting facilities. High-rise building facilities construction site should match the Qi adequate type of fire fighting equipment. In equipment installation and decoration should first install the fire water supply facilities ensure fire water, if necessary at each floor reserves the right amount of water used in fire. Site to set up a temporary evacuation signs, emergency lighting, eye-catching marked floors and staircases, installation of temporary fire broadcasting. Various types of equipment and facilities used for any other purposes is strictly prohibited.

Eight is the high-rise building facilities within the site materials, garbage, junk clogging channel is strictly prohibited, to guarantee the construction personnel to access shortcut around, make sure that in the event of a fire personnel evacuated. At the same time, to ensure that construction site around the fire trucks channel, a variety of fire-fighting vehicle can be convenient.
