1. Smoke -proof power distribution does not meet the requirements of norms
First, the power supply of the fan does not meet the requirements of high -level civil building load levels.Some power supply lines are not connected to the fire power supply, but to the floor lighting distribution box, some are designed with single -circuit power distribution lines, and some designs have no end -end power supply automatic switching device, which can not reach the first or secondary power supply power supply.The dedicated dual circuit requirements are required to set the regulations for automatic switching devices.The second is that the installation of the light -matching line does not meet the requirements.Some of the power distribution lines of anti -exhaust fan wearing PVC plastic pipes, and some wearing metal tube without painting fireproof coatings, which does not meet the fire performance requirements of pipe pipes.
The part of the mechanical anti -exhaust facilities should be set up without the requirements of the specifications:
1. High -rise civilian building smoke -proof staircases and front rooms with skirt rooms, or the front room of the fire elevator room may be used in the front room. When the podium is used, the outer window can be opened for natural smoke.When conditions, the front room or the front room does not set up a positive pressure supply system in accordance with the requirements of the specification.
2. Internal aisle that exceeds 20 meters without natural smoke, some designers have natural smoke due to the connected smoke -proof staircase. They believe that it has the conditions for natural smoke and fail to set up mechanical tobacco facilities in accordance with the requirements of the specificationsEssenceIn response to the above -mentioned problems, the fire supervision department should strengthen the supervision and management of the design and construction of construction smoke discharge facilities from the following aspects:
① The business guidance and training of the design and construction personnel of smoke -proof facilities should be strengthened.The fire departments of various places generally attach great importance to the business guidance and training of fire alarms and electrical, fixed (automatic) fire extinguishing facilities. The design and construction personnel of smoke -proof facilities are often ignored during the training process.
② The construction of the construction unit shall be implemented by the construction unit of the fire -proof facilities shall be implemented.Anti -anti -exhaust facilities are an important part of the automatic fire protection facility of the building. The construction unit shall be borne by the fire protection facility construction unit in accordance with the regulations. However, the construction of non -smoking facilities in many projects is installed by the air -conditioning professional construction unit.
③ When the construction map is reviewed by the construction drawing, the fire supervision department shall pay attention to the review of the design of smoke -proof facilities.Type, the setting of the smoke exhaust port, and the smoke -proof partition, etc. are conducted until review, and the supervision and management of smoke -proof facilities should be strengthened during the construction.The problem, guide and urge the construction unit to carry out rectification.
The above is the problems that may be encountered and solved the countermeasures that the fire exhaust fan may be encountered. If you want to know more related issues, please pay more attention to us —
