Office area fire protection design code, office building fire protection design code?

One: the problem of fire sprinklers in office decoration.

Before the office renovation and renovation, usually the fire protection renovation of the whole building has passed the acceptance; The property company or developer will have a copy of the fire acceptance speech that can be provided. Shaanxi recommended Shaanxi Wanpu Fire Protection for the secondary fire protection, for fire protection design, review, declaration, filing, drawing review, review, installation, transformation, testing, acceptance procedures, opening permits, safety inspections, maintenance and other fire protection renovation construction projects and interior decoration design and construction can be done. Many owners or decorators mistakenly think that the office can be renovated directly without fire renovation, which is an extremely wrong concept, because the state stipulates that the house must be renovated again when it is renovated.

One of the most important is the problem of fire sprinkler, we all know that the ceiling is usually suspended during decoration, which leads to the sprinkler sealed into the ceiling layer, which is extremely incorrect and should be moved to the sprinkler head below the ceiling to be considered a qualified sprinkler transformation.

2: Set up fire hydrants for office decoration.

There are strict requirements for the setting of office fire hydrants, which can not be designed at will, and there are usually three requirements: first, the location of fire hydrants should be in public places, such as office halls, corridors, etc., and should not be designed in closed rooms; Second, the height of the fire hydrant must comply with the relevant specifications, and the height cannot be arbitrarily set according to your own ideas; Third, the water in the fire hydrant cannot be used except for emergency fire extinguishing.

Three: office decoration emergency light problem.

Emergency lights are one of the equipment that must exist in the office fire renovation, and their role is to facilitate temporary lighting in the event of a fire and power failure, so as to ensure that personnel can escape in a visual situation. Hyatt Decoration reminds you that, like fire hydrants, emergency lights have clear regulations on the location of the device, the height of the device, and the distance between the lights.

Four: Office decoration and safe entrance consideration.

Obviously, the office is a public space with a high population density, so the number of safe entrances must be kept at two or more to facilitate the evacuation of people in case of emergencies. Many people at the beginning of the office decoration, only retain a safe entrance or simply the entrance gate is the entrance, such a fire design must be unreasonable designer introduction, if the office of the safe entrance is not enough, the need to carry out a certain transformation of the house structure, to ensure the existence of more than two or two safe entrances.

Five: the problem of smoke detectors in office decoration.

Smoke detector is a kind of fire-fighting equipment that measures the concentration of smoke, and it is usually installed at the top in the office space, and you may find that there is such equipment before the decoration construction and mistakenly think that there is no need to adjust it during the decoration. This is not standardized, because the fire protection stipulates the area used for each smoke detector, and if the functional space partition changes, the corresponding number of smoke detectors should be increased or adjusted.

Six: Evacuation distance and smoke exhaust problems in the office.

If the distance is more than 20 meters and the conditions for natural smoke exhaust are not met, mechanical smoke exhaust needs to be considered.

1. If the construction site of the office decoration unit is within 500 square meters, it must be equipped with at least two fire extinguishers of more than 4 kg.

firecracker must be within the validity period.

2. The office decoration unit is strictly forbidden to cap the additional isolation wall to the ceiling or the top, and each additional isolation room must be equipped with at least one independent smoke detector and one sprinkler. At least one smoke and one shower must be set up for every 50 square meters, and the area of less than 50 square meters is calculated as 50 square meters.

3. All smoke detectors in the unit must be able to connect with the fire control system.

4. Sprinkler, sprinkler pipe, fire hose, fire hydrant and other fire-fighting facilities cannot be damaged, and it is strictly forbidden to change their direction and use.

5. During the construction of the decoration unit, if open flame operation is required, an application must be submitted to the management office in advance. After the approval of the management office, the open flame operation can be carried out.

6. It is strictly forbidden to occupy the fire escape of the construction tools, materials, garbage and other materials of the office decoration unit. Fire water shall not be used for any reason.

Although the building fire protection design code has a certain inhibitory effect on the building in the event of a fire, there are still many problematic provisions in it. When designers design for these regulations, it is easy to be misled or overwhelmed, so as to subjectively set up fire protection facilities, resulting in the high number of accidents caused by fire. Therefore, in order to effectively control this problem, the building design and building use should be comprehensively improved to make the regulations of the problem be revised, so as to effectively prevent and control the fire, reduce the number of accidents, ensure the safety of people's lives and property, and create a harmonious and beautiful society.

Code for fire protection design of office buildings:

1. The office building should be determined according to the nature of use, the scale of construction and the different standards.

2. The office building should be determined according to the building modulus according to the use requirements, base area, structure selection and other conditions, and should create conditions for future transformation and flexible separation.

3. When office buildings, apartments and hotels are built together, they should comprehensively consider the mutual relationship in plane function, vertical transportation, fire evacuation, construction equipment, etc., and make reasonable arrangements. The comprehensive office building should be divided into entrances and exits according to different functions, and organize internal and external traffic routes.

4. Generally, the departments with more external contacts should be arranged near the main entrances and exits. Confidential departments should be relatively concentrated and appropriately separated from other departments.

The fire-fighting facilities that need to be on the office building generally include: fire alarm system, fire alarm button, fire extinguisher, fire alarm display and fire water pipeline, fire cable, fire hydrant belt, etc., and also need to install some keys and intelligent fire fighting equipment, such as fire alarm controller, intelligent fire alarm control system, intelligent smoke alarm system, intelligent fire door, etc.

Problem-related suggestions: Before carrying out the installation of fire-fighting facilities and facilities, you should apply to a professional fire-fighting company for a by-side defense design scheme to meet the fire protection requirements of the building, install qualified fire-fighting facilities in accordance with the requirements of the fire-fighting design plan, and regularly maintain fire-fighting facilities to ensure fire safety.
