The height that a high-level fire water tank should set in a building has always been a subject of controversy. The location and volume of the high-level fire water tank have a great influence on the effectiveness of fire fighting work. In order to maximize its function, the fire safety department responds to the related settings of water tanks. The content is carefully studied, and whether the high-level fire-fighting tank water storage system needs to be separated from the fire hydrant water storage, or the water storage requirements and the tank volume are carefully discussed, so that the fire can be effectively controlled after the fire in the building to avoid the spread of the fire. , resulting in greater economic losses and casualties. High-level fire water tanks are important water storage equipment in fire protection work. There are certain requirements in the relevant “Building Fire Protection Code†in China. Therefore, relevant designers need to set up the water tanks in accordance with the rules and regulations so as to ensure the high level of fire tanks . Items are up to standard.

1.Installation and debugging <br> The foundation can use concrete bar beam, or I-beam. Diagonal corners of modular stainless steel water tanks are provided with air permeable air filtering devices, the size and quantity of which are determined by the user according to the size of the inlet. Lacing is used inside the combined stainless steel water tank. Each nozzle flange is 1.0MPa standard flange. In the arrangement of the position of the combined stainless steel water tank, reference shall be made to the hygiene specification of the secondary water supply facility of GB 17051-1997. When the specification or orientation of the combined stainless steel water tank is not suitable for actual use, the stainless steel water tank designer shall put forward the determination according to actual needs.
2.Scope of action <br> Combined stainless steel water tank is widely used in real estate, industrial and mining, enterprises, residential, hotels, restaurants and other buildings, as drinking water, fire water and food quality, water, food, health And other water storage facilities.
3. The box process <br> The lightweight, beautiful and high-quality stamping process of the box body not only ensures the maximum pressure requirement of the box body, but also reduces the material thickness and meets the beautiful and practical requirements of the box body.
High-level fire-fighting water tank structure features <br> High-level FRP fire-fighting water tank structure is unique: With special sealing strips, full bolt connection structure, easy assembly, no leakage and incomplete sealing phenomenon, plus the special inner tie rod structure, so that the mechanical properties are more reasonable . The high-level fire-fighting water tank box of FRP is quick to construct: standard molded plate; it can be assembled arbitrarily without lifting equipment. The styling should meet the requirements of users, and the volume can meet all design requirements. There is no special requirement on the installation site.
High-level fire-fighting water tank capacity provisions <br> A high-rise public building, should not be less than 36T, but when the building height is greater than 100 meters, should not be less than 50T, when the building height is greater than 150 meters, should not be less than 100T.
Multi-storey public buildings, Class II high-rise public buildings and a high-rise residential building should not be less than 18T. When a high-rise residential building is more than 100 meters in height, it should not be less than 36T.
Second-class high-rise residential should not be less than 12T.
Multi-storey houses with a building height of more than 21 meters should not be less than 6T
When the design flow of industrial building indoor fire water supply is less than or equal to 25L/S, it shall not be less than 12T, and when it is greater than 25L/S, it shall not be less than 18T
Stores with a total construction area greater than 10,000 m2 and less than 30000 m2 should not be less than 36T, shops with a total construction area greater than 30000 m2 should not be less than 50T, and should be larger when inconsistent with the first paragraph of this Article.
High-level fire water tank setting height <br> High-level fire water tank is generally set at the highest point of the building. Most of the building projects in China are designed in this way. However, some high-rise buildings do not consider the use of water tanks when setting high fire tanks. , and there is no pressurization facility, sometimes the tank will not work. The pressure of municipal water supply networks in many cities in China cannot bring the fire protection system into a state of constant high pressure, and the fire protection system in a general building uses a temporary high-pressure water supply system. However, the reliability of the water supply system for the temporary high-pressure water supply system is relatively low. Therefore, a high-level fire water tank should be installed in the building using the system. In a high-rise building, the most unfavorable hydrostatic pressure of hydrant generally cannot be lower than 0.07 MPa, while the most unfavorable point water pressure of automatic sprinkler system cannot be lower than 0.05 MPa. Therefore, when a high-level fire water tank is installed in a building, it needs at least Above 7.5m, the minimum water level is too high if this requirement cannot be met. When the pressure of the automatic sprinkler system is in use, it belongs to dynamic pressure. Therefore, when designing, it is necessary to consider the loss during water spraying. The length of such a system is relatively long. In the process of circulation, the head loss is relatively large, in order to ensure the water spray. The pressure also needs to consider the gravity flow, so when setting the height of the fire tank, it will generally be higher than the fire hydrant system. However, after investigation, most of the construction units did not design this way, but set up booster facilities in the building, so as to meet the requirements of the fire fighting system for water pressure.
Pressurized facility is a relatively common object in high-rise buildings. It has a great influence on the effectiveness of fire-fighting facilities, and it is a tool that the high-level fire-fighting water tank needs to reach the water pressure. It is usually a booster pump or a pressure water tank. Constituted. The pressurization setting is a facility for maintaining the pressure of the fire protection system. If there is no pressurization setting, the high fire water tank can not be set at the highest position of a high-rise building. Therefore, the height of the high fire tank is higher than that of the pressurization facility. relationship. The gravity flow of the water storage tank in the water tank cannot meet the requirements of the fire system for the water pressure. As long as it is equipped with pressurized facilities, the position of the high fire water tank can be adjusted at will. In order to ensure the beauty of the building, some building units do not have functional rooms on the roof of the building. However, considering the safety of fire protection in buildings, the position of the fire tank must be adjusted. It is better to set it on the top floor of the house and it needs to be increased. The number of pressurized facilities to ensure the function of the fire fighting system. Therefore, the setting of the height of the high-level fire water tank is also related to the preferences of the architectural designers. The function and structure of the building are different, and the design of the roof is also quite different. When the high-level fire water tank is installed, the building safety must be ensured. One principle. High-level fire water tanks have a direct bearing on the safety of high-rise buildings. In order to ensure the fire pressure of the fire fighting system and automatic sprinkler system, booster facilities must be added at appropriate locations so that the height of the high-level fire tanks can be set. Adjust freely to ensure the appearance of the building under the premise of safety.
“Building Design Fire Protection Codeâ€, Item 8.3.3 stipulates that fire-fighting hose reels shall be provided for the personnel-intensive public buildings with indoor fire hydrants and other public buildings below the size of Article 8.3.1 of this Code; the building area is greater than 200m2. Commercial service outlets should be equipped with fire hose reels or portable fire hoses.
"High-rise Civil Building Design Fire Prevention Code," the provisions of Article 7.2.4: high-level hotels, important office buildings, a type of building commercial buildings, exhibition buildings, comprehensive buildings, and other high-rise buildings with a height of more than 100m, fire reel should be set The amount of water used may not be included in the total amount of firefighting water. Article 7.4.9 stipulates that the distance between the fire reel should ensure that one flow of water can reach any part of the indoor floor, and the installation height of the fire reel should be easy to access.
