Fire engineering construction significance and matters needing attention

The most important thing in fire protection construction is to do a good job in fire safety work. With the continuous development of China's construction engineering field, building fire protection engineering has become an important part of construction. Due to the complex volume of buildings, complex structures and extensive coverage of fire protection systems, the demand will naturally increase. People have also put forward higher requirements and standards for the fire safety of buildings and the reliability of fire protection systems. In addition to the optimization of engineering design, equipment and materials, fire protection engineering will also require the safety of fire protection construction quality. The quality of the project directly affects the normal operation of the fire fighting facilities, and even leads to the occurrence of fire.

The construction process of fire engineering construction must be carried out in accordance with certain specifications. First of all, installation preparation and preparation of relevant materials must be carried out before construction. Before fire fighting construction, Party A must be assisted in the design review of fire fighting facilities. Without design review or unqualified design review, Party A shall not carry out construction without authorization. Relevant materials must be reported to the fire department and fire fighting construction mobilization permit must be obtained. Materials selected for fire fighting construction must be registered with the fire department and have the permit issued by the fire department. After the fire fighting construction, the debugging and acceptance of the fire fighting system should also be carried out.

With the continuous development and progress of society, modern buildings continue to stand, the quality of fire construction has become an important guarantee for building safety. Standardized and safe fire fighting construction can prevent and control the occurrence of fire in time and effectively. When a fire occurs, the fire alarm system will detect the fire in the first time, and remind people of the occurrence of fire through the signal alarm. People can control and extinguish the fire in time through the fire extinguishing system such as fire pump and fire hydrant, so as to minimize the loss of people's life and property safety caused by the fire, it is necessary in fire safety. 1. The air duct shall be tested for light leakage and air leakage. The light leakage test shall be done by the construction unit, with no more than one light leakage point per 10M (not after the installation of fans and air valves). The energy-saving model shall be used for the first light leakage test. The air leakage test shall be entrusted by the construction unit to a third party (reason: if smoke leaks during smoke exhaust, losses will be caused); to master the essentials and methods of light leakage air leakage test;

2. There should be unpacking inspection records when the machine arrives. It is necessary to check whether the machine power is greater than the design power. In addition, the conformity of the brand should be checked;

3. Domestic water quality test report (water inlet: water pump, water outlet: end of residence, one for households less than or equal to 500, two for households greater than or equal to 500 than or equal to 1000, and so on);

4.PPR and steel-plastic pipes shall have hygiene and performance inspection reports (one for each general contractor and one for each material of different materials);

5. There shall be special joint review records of drawings for fire fighting, and the thickness of galvanized layer shall be detected for galvanized steel pipes;

6. The drain pipe larger than Φ110 shall be provided with door-type hanger at intervals, instead of only using clamp hanger;

7. Iron casing shall be installed when the air duct enters the fan room, and hanger shall be set separately for the fire damper (in the fan room);

8. Disinfection shall be carried out by the construction unit (washing with bleaching powder water);

9. Nozzle shall be made under the air duct larger than 1200, and anti-sway bracket shall be made for the air duct (usually done at the time of final fixation);

10. The casing of the electrical circuit should use the same kind of pipe, not a steel pipe, a plastic pipe;

11. The length of the straight section of the bridge is greater than 30 meters, and the expansion joint shall be set.

12. The fire-fighting flexible joint shall have a non-combustible certificate, and finally can be ignited on site.
