There are installation height requirements for fire sprinkler heads with and without suspended ceili

In places with suspended ceilings, the sprinkler heads are arranged under the ceiling, and they can be arranged at a certain distance and equal distance according to the danger level of the building. The sprinkler head is available in a droop type or a ceiling type. In places without suspended ceilings, spray on the sprinkler.

In addition to arranging according to a certain spacing, the influence of beams or other obstacles should also be considered, and the design code section "the distance between the sprinkler head and the obstacle" has been specified in detail.

Article 1 of the design code stipulates that in addition to the sprinkler head installed under the ceiling, the distance between the splash tray and the roof of the upright and drooping standard sprinkler head shall be 75mm and 150mm. It further specifies the layout requirements in several cases:

1. When the sprinkler head is arranged on the plane below the bottom surface of the beam or other obstacles, the distance between the splash tray and the top plate should be 300mm, and the vertical distance between the splash tray and the bottom surface of the beam and other obstacles should be 25mm and 100mm.

2. When the sprinkler head is arranged between the beams, it should comply with the provisions of this specification. When there is real difficulty, the distance between the splash tray and the top plate should be 550mm. When the sprinkler head arranged between the beams, and the distance between the sprinkler splash tray and the roof reaches 550mm, the sprinkler head should be added below the bottom surface of the beam.

3. The vertical distance between the splash tray and the bottom surface of the ribbed beam plate should be 25mm and 100mm.

4. In places where the clearance height is not more than 8m, and the spacing is not more than 4m and 4m are arranged, one sprinkler can be arranged between the beams, but the water spray intensity should still meet the regulations.

1. The arrangement of upright and drooping nozzles, including the same water distribution 32313133353236313431303231363533e78988e69d8331333365653238

The spacing of the sprinklers on the branch pipe and the spacing of the adjacent water distribution branches should be determined according to the water spray intensity of the system, the flow coefficient of the sprinkler and the working pressure.

2. In addition to the ceiling-type sprinkler and the sprinkler installed under the ceiling, the distance between the splash tray and the roof of the upright and drooping standard sprinkler should not be less than 75mm and should not be greater than 150mm.

3. When the sprinkler head is arranged on the plane below the bottom surface of the beam or other obstacles, the distance between the splash tray and the top plate should not be greater than 300mm, and the vertical distance between the splash tray and the bottom surface of the beam and other obstacles should not be less than 25mm and should not be greater than 1OOmm.

Extended information: fire sprinkler is used in the fire sprinkler system, when a fire occurs, the water is sprinkled through the sprinkler splash tray to extinguish the fire, which is currently divided into drooping sprinkler head, vertical sprinkler head, ordinary sprinkler head, side wall sprinkler head, etc.

1. The drooping sprinkler is the most widely used sprinkler, which is installed on the water supply branch pipe by sagging, and the shape of the sprinkler is a parabolic shape, spraying 80 100% of the total water volume to the ground. To protect the room with a suspended ceiling, a sprinkler head should be arranged under the ceiling, and a drooping sprinkler head or a ceiling-type sprinkler head should be used.

2. The upright sprinkler head is installed upright on the water supply branch pipe, the sprinkling shape is a parabolic shape, and 80 100% of the total water volume is sprayed downward, and at the same time, there is a part of the vertical sprinkler head sprayed to the ceiling, which is suitable for installation in places with more moving objects and easy to impact, such as warehouses, and can also be concealed at the roof in the ceiling mezzanine of the room to protect the boron of the ceiling with more flammable materials. (In places where the ceiling is not made, when the water distribution branch pipe is arranged under the beam, the upright type should be used.) For areas that are susceptible to collisions, a sprinkler head with a protective cover or a ceiling-type sprinkler should be used).

Depending on the country. This specification is based on the spirit of our Ministry of Jianbiao [1996] No. 4 document.

Accumulated many years of experience in building water supply, drainage and heating engineering design, materials and construction, in accordance with"Verification of dissociation

Strengthen acceptance, improve means, and process control"policy, carried out a complete revision, added the building water system and.

Installation of swimming pool water systems, heat exchange stations, installation of low-temperature hot water radiant floor heating systems, and new materials such as:

composite pipes, plastic pipes, copper pipes, new radiators, quick-assembly pipe fittings, etc.), and more.

In August 2001, the main issues were repeatedly revised after extensive consultation with relevant units across the country

Menstrual review finalized.

This specification mainly stipulates the division of project quality acceptance, procedures and organization should be in accordance with the national standard "Construction Worker.

The provisions of the unified standard for construction quality acceptance GB50300; The use of functions within the inspection and inspection is proposed.

Appearance; The quality inspection methods of the main control project and the general project in each sub-project are listed.

This Code may need to be partially revised in the future, and the information and content of the provisions regarding the partial revisions will be published here.

Engineering Construction Standardization" magazine.

The provisions of this specification marked in bold font are mandatory provisions and must be strictly enforced. In order to improve the quality of the specification, all units are requested to pay attention to summarizing experience and accumulating information in the process of implementing this specification.

The suggestions are fed back to the Shenyang Municipal Urban and Rural Development Committee and the national standard "Construction Quality of Building Water Supply and Drainage and Heating Engineering".

Acceptance Specification" management group.

It depends on the situation in which there is one in every place: the construction worker, you go and ask him.

In general: the spray is 5-15 cm.

In the case of compulsion: 8-15 cm.

In fact, suspended ceilings and.

The height requirements for the fire sprinkler head without a ceiling are strictly regulated. When in the beam specialty.

When the sprinkler head is arranged, it should be in accordance with the provisions of the specification. The distance between the splash tray and the top plate is 550mm, and the distance between the sprinkler head and the top plate is still not in accordance with the regulations, and the sprinkler head should be added under the measuring ground. In places with a clearance height of no more than 8 meters, the distance between them should not exceed 4 meters or 4 meters.

It makes sense that the dry installation height of the fire sprinkler head of the red chandelier is not very demanding.

The installation height of the fire sprinkler with a suspended ceiling is about the same as that of a fire sprinkler without a suspended ceiling, which seems to be a data. I remember that even if you have a suspended ceiling in the position of the suspended ceiling, the fire sprinkler must be opened there and leak out, as if the data I have seen is 2.7 meters, meters.
